Abstract
The invention discloses a thin-walled shifting fork turning clamp, relates to the field of machining and in particular relates to the thin-walled shifting fork turning clamp which comprises a clamp main body, wherein the clamp main body is a cylindrical truncated cone; a plurality of stop dogs are arranged on one end surface of the clamp main body; two stop dogs are arranged on the clamp main body in parallel; each stop dog is connected with a bolt through a threaded hole; two cylindrical pins are also arranged on the clamp main body and are a center positioning pin and a limiting pin respectively; the center positioning pin and the stop dogs which are arranged in parallel with the center positioning pin are arranged on the circumference of a same circle; the center of the circle is coincided with the center of circle of the end surface of the clamp main body; threads are formed in the top end of the center positioning pin; and the top end of the center positioning pin is connected with a nut. The thin-walled shifting fork turning clamp has a simple structure, is convenient in operation, can well ensure the size, form and position accuracy when a workpiece is processed and improves the production efficiency.
Description
Technical field
The present invention relates to field of machining, be specifically related to thin-walled shift fork turning clamp.
Background technology
Dialling is again the strength member realizing gearbox gear, because its shape matching is special, clamping corrects more difficult, process tool to acquire a certain degree of difficulty, particularly shape is comparatively complicated, size and the accuracy of form and position require higher, this type of part that shift fork head wall thickness is thinner, adding man-hour because process is improper or the factor such as clamping deformation, be difficult to the machining accuracy ensureing part, to directly affect the gear performance of gearbox, the processing difficulties of part mainly contains the following aspects: (1) design of part is comparatively unique, the structure of this part complex-shaped is comparatively complicated, endoporus, two sides, end face, groove, hole, clamping during the shift fork head processing of two places, correct more difficult, secondly on this workpiece, between each hole, dimensional accuracy and the accuracy of form and position require higher, process is difficult to ensure.(2) because part is thinner, clamping method did not easily produce distortion at that time, during processing two sides, conventional method be adopt by use pressing plate pressure part surface on not the place of processing carry out the fastening of part, although adopt this kind of method can by fastening parts on fixture, but because part compression spot size is thinner, the mode adopting this kind to compress is easy to make part produce elastic deformation, after one, face car is complete, once unclamp fixture, elastic deformation will recover, and thus cannot ensure dimensional accuracy and the accuracy of form and position of two sides 2.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, easy to operate, and dimensional accuracy and the accuracy of form and position when well can ensure work pieces process, the thin-walled shift fork turning clamp of enhancing productivity.
Thin-walled shift fork turning clamp of the present invention, comprise jig main body, described jig main body is column round platform, described jig main body one end face is provided with some blocks, wherein two blocks are disposed in parallel on jig main body, described block is all connected with bolt by screwed hole, jig main body is also provided with two straight pins, be respectively centralized positioning pin and spacer pin, described centralized positioning pin and the block be set up in parallel are positioned at same circle circumferentially, the center of circle of this circle overlaps with the center of circle of jig main body end face, described centralized positioning pin top is provided with screw thread, and be connected with a nut.
Preferably, block is three, and the angle between another block and two blocks arranged side by side is greater than 90 ° and is less than 180 °.
Preferably, described centralized positioning pin is also provided with an opening pad.
Structure of the present invention is simple, easy to operate, and dimensional accuracy and the accuracy of form and position when well can ensure work pieces process, enhance productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of thin-walled shift fork turning clamp.
Reference numeral: 1-jig main body, 2-hold-down bolt, 3-block, 4-workpiece, 5-centralized positioning pin, 6-nut, 7-opening pad, 8-spacer pin.
Detailed description of the invention
Thin-walled shift fork turning clamp of the present invention, comprise jig main body 1, described jig main body 1 is column round platform, described jig main body 1 one end face is provided with some blocks 3, wherein two blocks 3 are disposed in parallel on jig main body 1, described block 3 is all connected with hold-down bolt 2 by screwed hole, jig main body 1 is also provided with two straight pins, be respectively centralized positioning pin 5 and spacer pin 8, described centralized positioning pin 5 is positioned at same circle circumferentially with the block 3 be set up in parallel, the center of circle of this circle overlaps with the center of circle of jig main body 1 end face, described centralized positioning pin 5 top is provided with screw thread, and be connected with a nut 6.Described block 3 is three, and the angle between another block 3 and two blocks 3 arranged side by side is greater than 90 ° and is less than 180 °.Centralized positioning pin 5 is also provided with an opening pad.
Using method is the cylindrical in three-jaw self-centering chuck clamping device main body 1, then the hole that part had cut with scissors is coordinated with the centralized positioning pin 5 on fixture, workpiece 4 end face and jig main body 1 plane are close to, turning of work piece 4, workpiece 4 side is made to be close on spacer pin 8, load onto opening pad 7 at centralized positioning pin 5 place and fastening nut 6, then tighten three hold-down bolts 2 respectively, just workpiece 4 can be fastened on fixture.Because nut 6 is from workpiece 4 axial compression part, and workpiece 4 belongs to face and contacts and coordinate in thickness comparatively large and end face and jig main body 1 surface herein, thus clamps herein and is not almost out of shape generation.Three hold-down bolts 2 are all from workpiece 4 radial compaction workpiece, even if there is distortion, this distortion also all can not affect the machining accuracy of two sides towards part radial direction, therefore, the distortion that traditional employing pressing plate mode clamping workpiece can be avoided to cause, guarantees the dimensional accuracy that two sides process and the accuracy of form and position.
