Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 and 2, an embodiment of the present invention includes:
a jig for machining an eccentric through hole, comprising: the clamping device comprises a fixed seat 1, a jacking device 2 and a clamping disc 3, wherein the fixed seat 1 and the jacking device 2 are fixed at the left end and the right end of the upper surface of the clamping disc 3; the jacking device comprises a jacking block 21, a jacking bolt 22 and a jacking seat 23, wherein the jacking bolt 22 is in threaded fit with the jacking seat 23 and then penetrates through the jacking seat 23 to jack the jacking block 21.
Further illustrating the principle of the jig for machining an eccentric through hole: the utility model relates to an anchor clamps for processing eccentric through-hole is used for pressing from both sides the dress and has eccentric through-hole machined part, makes its processing that is fit for ordinary lathe, and the machined part that adopts in this embodiment is box 4 is cut to the quadruple. Two positioning pins 11 are arranged on one side of the fixed seat 1 of the clamp up and down, and the positions of the two positioning pins 11 are consistent with the groove on the side surface of the four-in-one shear box body 4. When processing, the worker clamps the clamping disc 3 of the clamp for processing the eccentric through hole to the clamp of the machine tool, then uses the checking fixture to calibrate the position of the reference hole 31 by the lathe, after the positioning pin 11 on the fixed seat 1 is aligned with the groove on the side surface of the quadruple shear box 4 to position, the hexagon socket head cap screw 22 is screwed by using the hexagon socket head wrench, one end of the tightening screw 22 is tightly pressed against one side surface of the jacking block 21, the other side of the jacking block 21 is tightly pressed against the quadruple shear box 4, the quadruple shear box 4 is fixed on the clamp, at the moment, the position of the eccentric through hole 41 to be processed on the quadruple shear box 4 is matched with the processing axis of the machine tool, and then the eccentric through hole 41 on the quadruple shear box 4 can be processed.
