Description
Technical field
The utility model relates to automobile connecting bar clamp for machining field, is specifically related to a kind of special fixture of connecting-rod bolts export processing.
Background technology
In the production process of automobile connecting bar, adopting two sides, a hole is the conventional positioning mode.But in up-to-date link design, cancelled the locating surface of major part both sides,, needed the new anchor clamps of design to accomplish the processing of connecting rod so the conventional positioning mode no longer is suitable for novel link for the intensity of strengthening the connecting rod pressure-bearing surface.
The utility model content
The utility model provides a kind of connecting-rod bolts outlet special fixture, the orientation problem when having solved newly designed Machining of Connecting Rod.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of connecting-rod bolts export processing special fixture; Comprise connecting rod, clamping workpiece and hydraulic cylinder, towards the workbench clamping, said clamping workpiece comprises major part alignment pin, microcephaly's alignment pin, backing plate, riser, base plate, floor and briquetting to big end down; Said riser is fixed on the base plate through floor; Base plate links to each other with the machining center workbench, and riser is vertical with base plate and workbench, and the major part alignment pin is installed in the hole of backing plate; Backing plate and microcephaly's alignment pin are connected on the riser through bolt, have four holes to link to each other with riser on the backing plate in addition; Said hydraulic cylinder drives briquetting and is pressed in the big end middle part.
Said backing plate can be around the slightly inching of microcephaly's alignment pin.
Said major part alignment pin is connected with the hole interference of backing plate.
Said major part alignment pin adopts the chamfered edge pin, and the one side that said backing plate supports major part is slightly thicker than the face that supports the microcephaly.
The utility model is simple in structure, be easy to realize that the major part alignment pin adopts the chamfered edge pin, and interference is installed in the backing plate hole; Microcephaly's alignment pin passes another hole of backing plate and adopts bolt to be connected with riser, has four holes to link to each other with riser on the backing plate in addition, and connecting rod adopts the mode of Position with One Plane and Two Holes to locate; Major part adopts the chamfered edge pin; The one side of the major part of backing plate support simultaneously should be slightly higher than the face that supports the microcephaly, effectively prevented the location, so these anchor clamps can be suitable for various connecting rods; No matter have or not side-locating face, the location is simple, reliable, accurate simultaneously.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is this practical front view;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Be labeled as among the figure:
1, major part location chamfered edge pin; 2, microcephaly's alignment pin; 3, backing plate; 4, riser; 5, base plate; 6, floor; 7, briquetting; 8, hydraulic cylinder; 9, connecting rod.
The specific embodiment
Shown in Fig. 1 to 3, provided a specific embodiment of the utility model, among the figure; Comprise connecting rod 9, clamping workpiece and hydraulic cylinder 8; Towards the workbench clamping, clamping workpiece comprises major part location chamfered edge pin 1, microcephaly's alignment pin 2, backing plate 3, riser 4, base plate 5 and floor 6 and briquetting 7 to connecting rod 9 major parts down, and wherein hydraulic cylinder 8 is the rotating hydraulic cylinder; Said hydraulic cylinder 8 is connected on the riser 4; Riser 4 is equipped with copper sheathing reaching antifriction effect, and riser 4 is installed on the base plate 5 that links to each other with the machining center workbench through floor 6, and riser 4 is vertical with base plate 5 and workbench.In the hole of chamfered edge pin 1 through interference installation and backing plate 3, major part location, the tapping hole is to guarantee detachability on the chamfered edge pin 1 of major part location; Backing plate 3 tops link to each other with riser 4 through 4 screws, and the latter half links to each other with riser 4 through microcephaly's alignment pin 2 and inner screw; Because four apertures on top are greater than the diameter of bolt, so backing plate 3 can be done the trace swing around microcephaly's alignment pin 2, so that adjustment connecting rod 9 levels, two bolts go out the unanimity of open height.
The Special Clamps Design of the utility model is " two holes one side " formula location, and hydraulic cylinder 8 drives briquetting 7 and is pressed in connecting rod 9 big centriciputs, and it is little that connecting rod is compressed the force deformation amount, prevents that the connecting rod warpage from causing mismachining tolerance.Backing plate 3 major part segment thicknesses have reduced because the position error that connecting rod 9 concentric reducer thickness errors cause a little more than microcephaly's thickness so simultaneously.
The utility model is simple in structure, be easy to realize, can be suitable for various connecting rods, no matter has or not side-locating face, and the location is simple, reliable, accurately simultaneously.
