Jig and clamping apparatus

We had known, workpiece must have fixed position relative to cutting cutting tool, and must secure firmly be in that locally. Workpiece is underlined after ending, still be necessary to have fixed position to the motion of the machine tool, and should secure work before machine treatment begins be in that locally. When wanting to process a few identical work, use jig and clamping apparatus can be replaced what undertake lineation operating to every workpiece is necessary, but in if be in,forginging, need to undertake lineation to a test specimen, come out in order to ensure workpiece can be machined through test specimen, also ensure at the same time strengthen costal region board, model core the place that wait is proper. The same point of jig and clamping apparatus depends on them be being contained can ensure workpiece is accurate fixed position and the device that intensify, and their different the bag in depending on jig be being operated in actual cutting contains the part that leads cutting tool, and clamping apparatus is done not have. Actually, the only cutting cutting tool that can be guided when cutting is broach, wring knife and similar milling cutter, because this jig is,use at getting to cut machine and clamping apparatus is used in other treatment craft. Clamping apparatus can include the cutting tool that has installing relative to location system. The advantage of 1 jig and clamping apparatus 1) leave out underline and other measures the method with outfit clip. 2) the worker of technical inexperience arrives in understanding workpiece can allow to locate truly. And cutting tool guides well and truly or the premise of installation falls, OK also and fast and undertake self-confidently operating. 3) it is easy to make the assembly of the spare parts becomes. Because all spare partses are inside little ultimate scope,regard as identical, and spare parts trial assembly and file cut an operation but leave out. 4) make the spare parts has interchangeability. If product big range is sold, the problem of spare parts can get simplifying. Bolt aperture often stays for bolt have 1.

The clearance of 0mm, because this reader perhaps is met,suspicion makes the necessity of accurate jig to this. But we must remember, once get moulding to become, it will be used at a lot of spare partses, the premium that makes accurate jig also is apportion on a large number of products. In addition, it is small that in machinery the error in rigging a process is accumulated breathtaking. Decide when clearance, we should ensure its habit asks, is not rough lay off and treatment come out. The fixed position of workpiece. In the space the condition of completely free unit falls, it has 6 freedom to spend. We use 3 mutual and perpendicular XX, YY, ZZ axis will state these 6 freedom are spent. Unit can move along an any axes, because this has 3 translation freedom,spend. Unit also can circle any an axes roll, because this has 3 rotational freedom to spend, add up to has 6 freedom to spend. When having fixed position to workpiece, we should be restricted as far as possible much freedom spends the precision that will ensure the operation achieves a requirement. Precision is assured by fixed position face, answer to define right fixed position side as early as possible in machining a process, if do not have the word that stem from other consideration and must use face of other fixed position, we should have all fixed position with these fixed position faces. If necessary word, new fixed position range should be located by old fixed position range treatment comes out. Clamp. Clamp device should make workpiece to cutting force. Clamping force cannot too big and cause workpiece is out of shape and destroy. Workpiece should prop up what nod in clamp below, in order to ensure by jig or clamping apparatus advocate frame will assume power, pass its to the workbench of the machine tool and lathe bed. When designing jig and fixture, the design of clamp device should ensure those who provide appropriate clamping force and operation is fast with safety. The definition jig of 2 jig is one kind is used ensure workpiece is in correct locally by bore, accuse whorl or the unit that wring aperture. It basically is formed by component of a clamp. This device holds work the bottom in a sclerotic sleeve, be inside sleeve and the broach in getting empty treatment course moves along sleeve. If the construction of workpiece is simpler, the mould can be placed on workpiece directly. However, below most circumstance, the mould is to be secured in a position workpiece is stayed in by mould holder. Such workpiece are machining around to be able to guide quickly derive mould. Jig makes bore, the manual method that wrings aperture and the rate that attack whorl and precision to compare a tradition is a lot of taller. Another its advantage is to use jig to be opposite the person that machine has too high skill to ask. The fixed position precision of aperture does not rely on handlers to rely on jig to assure however. Spacing jig is used in commonly use drill, wring the empty, unit that accuses whorl to go up. It won't be secured completely to be on the machine that uses it commonly, can move on the platform that sets drill, make sleeve is in the lower part of broach directly. Spacing jig is restricted actually and controlled the athletic route of cutting tool. If a few machine include to machine a process in treatment process, for example mill, dig, shape, turning is waited a moment, spacing clamping apparatus should be used. Clamping apparatus holds work in the clip when machine treatment, but differ with jig, did not lead the unit of cutting tool technically. 3 typical jig and jig of clamping apparatus model. Use the jig that machines 4 aperture for example, this workpiece already had been machined entirely besides 4 aperture. Workpiece has the opening that an accurate cutting becomes, use had had fixed position from aperture, end panel and cylinder. Not was necessary to limit the circumferential position around aperture antrum axes, because be machined till each aperture when, it is the photograph is symmetrical to this axes. Be secured to be on jig flat with 4 lining that will control bit, jig flat can be workpiece clamp through hand nut on equipment base. Typical milling clamping apparatus. Use the simple and easy clamping apparatus of the work that milling has completed other treatment for example. This workpiece is mixed twice of 4 Kong Zhong through base of base inside side fixed position. Workpiece is held to be in by clip proper place, cutting tool installation is installing a stage to go up, installation stage assures to install or cut the position and penetration. Clamping apparatus must locate at the workbench of the machine relatively, this is two rabbets that pass a clamping apparatus bottom a chamfer on built-in machine workbench will achieve. Clamping apparatus is through T bolt close prison on workbench, also embed the chamfer in workbench to go up. CNC Milling
