Low-cost modular drop hammer type impact fixture with non-single impact position point

Abstract

The invention discloses a low-cost modular drop hammer type impact fixture with a non-single impact position point, which is used for solving the technical problem that an existing fixture is poor inpracticability. According to the technical scheme, the fixture comprises a standard clamp, a supporting plate, a cover plate and rubber pads. The supporting plate is inlaid into a groove of the standard clamp and is capable of moving forth and back in the length direction of the groove; a test piece is arranged in the groove of the supporting plate to perform impact on different positions of the test piece; and the cover plate is arranged at the upper surface of the test piece to ensure the contact of the rubber pads at the two sides of the bottom portion of the cover plate and the test pieceand ensure the alignment of the four sides of the cover plate and the four sides of the groove of the standard clamp. The supporting plate with a customizable size solves the problem of supporting test pieces with different sizes; the rubber pads on the two sides of the cover plate solve the problem of keeping the same boundary condition of the test piece when different positions of the test pieceare impacted; the supporting plate and the cover plate which are easy to machine solve the problem that the overall cost of the clamp is too high, and practicability is good.

Description

technical field [0001] The invention relates to a jig, in particular to a low-cost, modular, non-single impact position drop-weight impact jig. Background technique [0002] refer to Image 6 . The document "Chinese Invention Patent with Application Publication No. CN106918503A" discloses a design and manufacturing method of a drop-weight impact fixture with a non-single impact position point. The fixture includes a pressing module 1 , a lateral movement module 2 , a longitudinal movement module 3 , a support base 4 and a positioning baffle 5 . The pressing module 1 is placed above the lateral movement module 2 , and the longitudinal movement module 3 is placed below the lateral movement module 2 . [0003] Place the test piece in the groove of the compression module 1, and change the impact point on the test piece by adjusting the positions of the lateral movement module 2 and the longitudinal movement module 3, so as to achieve the purpose of impacting different position...
