Abstract
The invention relates to a lifting lug plate machining clamp which comprises a supporting subplate used for supporting a to-be-machined lifting lug plate for machining. Geometric shape of the outer edge of the supporting subplate is identical with that of the outer edge of the to-be-machined lifting lug plate, a first positioning member and a second positioning member which are used for positioning the lifting lug plate are correspondingly arranged at positions, corresponding to two lifting holes of the lifting lug plate, on the supporting subplate respectively, a first pressing plate is arranged above the first positioning member, a second pressing plate is arranged above the second positioning member, and the first pressing plate and the second pressing plate are used for tightly pressing and fixing the lifting lug plate after being mounted on the supporting subplate. Direct machining can be realized after first-time clamping, one-pin one-plate positioning is not needed for machining, and second-time clamping is not needed, so that processing efficiency is improved; the lifting lug plate machining clamp machines according to the standard of the to-be-machined lifting lug plate, thereby being accurate in positioning, and machined lifting lug plate products are ensured to be uniform and meet requirements.
Description
Technical field
The invention belongs to clamp for machining technical field, be specifically related to a kind of shackle plate machine processing clamp.
Background technology
During CNC milling machine processing calabash shape shackle plate part, require chamfering 2mm × 45, other operations of workpiece complete, and two large faces process, two lifting hole(eyelet)s boring completion of processing, external arc surplus 2 ~ 3mm.CNC milling machine requires processing periphery circular arc and chamfering, and arc-shaped edges clamped one time can machine, but chamfering needs positive and negative twice clamping just can complete.Adding the milling cutter through thickness processing of external arc employing in man-hour diameter 40mm, not stratified in order to raise the efficiency.Concrete machining process: workpiece centering, processing excircles arc, chamfering, turn-over clamping, carries out reverse side chamfering.At this moment key is just that positive and negative two sides requires chamfering uniformity, can there is following problem in process:
(1) there is inconvenience in workpiece when centering.This workpiece can only position clamping with centre bore, and levelling two hole lines of centres are more time-consuming, bothersome, is batch production still more.
(2) even if centering workpiece, also there will be problem in processing, external arc fortunately controls, but the chamfering on both sides is just bad be ensure that.Be often front processing qualified, reverse side processing time, the circular arc of reverse side just there will be cut less than situation.
(3) this workpiece all will be processed a collection of substantially every month, often criticizes at 50 ~ 100 not etc.
In sum, designing and making simple fixture is necessary in actual process, workpiece can be made to carry out easy, positioning and clamping fast and accurately, to ensure the arc accuracy and the chamfering precision that add man-hour, and fixture to make every effort to structure simple, easy to make, there is certain versatility, can Long-Time Service be supplied.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem and a kind of shackle plate machine processing clamp is provided.
For achieving the above object, the present invention adopts following technical scheme:
A kind of shackle plate machine processing clamp, comprise one for supporting the support backing plate that shackle plate to be processed carries out processing, described support backing plate has the outer rim geometry consistent with the outer rim geometry of shackle plate to be processed, the support backing plate of this shape reserves feed space to cutter when having processing excircles arc on shackle plate, the position of two lifting hole(eyelet)s of corresponding shackle plate corresponding the first keeper be provided with for locating shackle plate respectively on described support backing plate, second keeper, the top of described first keeper is provided with the first pressing plate, top second pressing plate of described second keeper, described first pressing plate, second pressing plate is for being arranged at shackle plate after on described support backing plate, shackle plate is fixed and processes.
Described first pressing plate is by the first screw rod, the first nut check shackle plate, and described second pressing plate is by the second screw rod, the second nut check shackle plate.
Described first pressing plate has the unloading clip opening being convenient to unloading clip, and the second pressing plate has the unloading clip opening being convenient to unloading clip.
Described first keeper is a cylinder alignment pin, and the second described keeper is that a chamfered edge location is cut.
The upper bottom portion of described support backing plate is provided with two back-up blocks.
Described back-up block adopts T-shaped block.
Shackle plate machine processing clamp of the present invention is convenient is processed to form exterior arc surface on shackle plate, directly process after clamped one time, need not process a pin one plate location, also need not secondary clamping, thus improve working (machining) efficiency, and because this clamp for machining is according to shackle plate standard to be processed processing, accurate positioning, ensure that the shackle plate product processed is consistent, meet the requirements.
Accompanying drawing explanation
Figure 1 shows that the perspective view of a kind of shackle plate machine processing clamp that the embodiment of the present invention provides;
Figure 2 shows that the front view of a kind of shackle plate machine processing clamp that the embodiment of the present invention provides.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.
Shown in Fig. 1 ~ 2, a kind of shackle plate machine processing clamp, comprise one for supporting the support backing plate 1 that shackle plate to be processed carries out processing, the geometry that the outer rim of described support backing plate 1 is formed is consistent with the geometry of the outer rim of shackle plate to be processed, thus can be that processing excircles arc reserves feed space to cutter on shackle plate, the position of two lifting hole(eyelet)s of corresponding shackle plate corresponding the first keeper 2 be provided with for locating shackle plate respectively on described support backing plate 1, second keeper 3, the top of described first keeper 2 is provided with the first pressing plate 6, top second pressing plate 10 of described second keeper 3, described first pressing plate 6, second pressing plate 10 is for being arranged at shackle plate after on described support backing plate 1, shackle plate is fixed, process to facilitate.
Wherein, described first pressing plate 6 locks shackle plate by the first screw rod 4, first nut 5, and described second pressing plate 10 locks shackle plate by the second screw rod 8, second nut 9.
Further, described first pressing plate 6 has unloading clip opening 7, second pressing plate 10 being convenient to unloading clip and has the unloading clip opening 11 being convenient to unloading clip, like this, can improve efficiency of removing stage makeup and costume, thus enhance productivity.
