Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As it is shown in figure 1, for processing the fixture of connecting hole on weld yoke on a kind of lathe of the present invention, described weld yoke has central siphon connecting portion 400 and cross axle connecting portion 500, and central siphon connecting portion 400 is fixedly connected on the bottom of cross axle connecting portion 500. Cross axle connecting portion 500 is provided with two engaging lugs 501, these two engaging lugs 501 is respectively equipped with a connecting hole 502 to be processed, is formed with the end face A of arc-shaped between two engaging lugs 501.
On above-mentioned weld yoke, the clamped one time of the fixture being processed by the present invention of connecting hole is on lathe. Such as Fig. 2 to Fig. 5, clamping device of the present invention includes second gripper shoe the 21, second depression bar the 24, second pressing plate 25, setting circle boss 26, push rod 27 and is provided with the mounting body 1 of rectangle installing hole 11, second gripper shoe 21 is fixed in the installing hole 11 of mounting body 1, setting circle boss 26 is fixed in the second gripper shoe 21, and some push rods 27 are distributed in the second gripper shoe 21 along the circumferencial direction of setting circle boss 26. Four second depression bars 24 are one group between two is fixedly connected on the both sides, front and back of the second gripper shoe 21 respectively, second pressing plate 25 is rotatably coupled on the second depression bar 24, and the second pressing plate 25 pressure is touched on the end face A of cross axle connecting portion 500 and is closely against on push rod 27 by cross axle connecting portion 500.
The present invention installs in installing hole 11 inner position of mounting body 1 for ease of the second gripper shoe 21, is provided with step groove 12 in installing hole 11, corresponds ground, is provided with the positioning step 210 suitable with step groove 12 in the lower surface of the second gripper shoe 21.
