Abstract

The utility model provides a friction wear testing machine sample anchor clamps, relates to a mechanical fixture, including the anchor clamps body, twist grip, screw rod, slider mounting panel, screw. The rotary handle and the screw rod are connected with the clamp body through threads, the clamp body is provided with four rectangular holes, the sliding block penetrates through the rectangular hole and is connected with the sliding block mounting plate through a screw, the sliding block is mounted on the clamp body and can perform linear reciprocating movement, and the screw rod is moved and drives the sliding block to clamp a sample to be fixed by rotating the four rotary handles. The clamp can fix various samples for friction and wear tests, and the diversity of the samples for the friction and wear tests is increased.

Description

Sample clamp of friction wear testing machine

Technical Field

The utility model relates to a mechanical fixture, in particular to friction and wear testing machine sample anchor clamps.

Background

Most of the existing friction wear testing machines adopt a round testing stand to bear a test sample, the test sample is required to be a cylinder and the size of the test sample is fixed, and the difficulty of the friction wear testing is increased.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide an anchor clamps that can fix multiple sample, can realize the friction wear test of multiple sample to the not enough of above-mentioned prior art.

In order to solve the above problem, the utility model adopts the following technical scheme: the utility model provides a friction wear testing machine sample anchor clamps, includes the anchor clamps body 5, twist grip 1, screw rod 2, slider 3, slider mounting panel 4, screw 6, its characterized in that: the lower part of the clamp body 5 is connected with a cylindrical boss on the test bed through a round hole 8 on the cylindrical boss 7, the clamp body 5 is provided with four rectangular holes, and each rectangular hole is provided with a sliding block 3, a screw rod 2 and a rotating handle 1. The screw rod 2 is moved by rotating the four rotating handles 1, and the slide block 3 is driven to clamp the sample 7 to be fixed.

The utility model has the advantages that: the clamp is simple in structure, simple to install and convenient to operate, can clamp various samples to perform friction and wear tests, and increases the diversity of the friction and wear test samples.

Description of the reference numerals

In fig. 1, 1 rotates the handle; 2, a screw rod; 3, a sliding block;

in fig. 2, 4 slider mounting plates; 5, a clamp body; 6, a screw; 7, cylindrical bosses; 8, round holes;

in FIG. 3, 7 rectangular parallelepiped samples.

Detailed Description

The lower ends of the four sliding blocks 3 penetrate through four rectangular holes in the fixture body 5 respectively, and then are connected with the four sliding block mounting plates 4 through threads and screws 6, so that the sliding blocks 3 can reciprocate linearly along the long edges of the rectangular holes in the fixture body 5. The four rotating handles 1 are connected with the four screw rods 2 through threads, and then the four screw rods 2 are connected with the clamp body 5 through threads. The screw rod 2 is moved by rotating the four rotating handles 1, and the slide block 3 is driven to clamp the sample 7 to be fixed. The design of the 5 below of anchor clamps bodies has four cylinder boss 7 structures, is equipped with round hole 8 on the cylinder boss 7, can install fixedly with the cylinder boss on the test bench.

Claims (1)

1. The utility model provides a friction wear testing machine sample anchor clamps, its characterized in that, anchor clamps include the anchor clamps body, twist grip, screw rod, slider mounting panel, screw, and wherein twist grip and screw rod, the anchor clamps body passes through threaded connection with the screw rod, and the anchor clamps body is opened has four rectangle mouths, and the slider passes the rectangle mouth and passes through the screw to be connected with the slider mounting panel and install on the anchor clamps body and can carry out reciprocating sliding, makes the screw rod remove and drives the slider and cliies the sample and make it fixed through four twist grip of rotation.
