Description
Technical Field
[0001] The present application relates to the field of fixing devices, and in particular to a fixing device for a coarse aggregate polishing specimen. Background Art
[0002] In materials science research, the coarse aggregate polishing test is an important means to evaluate the wear resistance of aggregates. To ensure the accuracy of the test results, the relative position of the measuring instrument and the polished specimen must be kept stable during the test to avoid relative movement.
[0003] Traditional methods usually use simple clamps or glue to fix the two sides or bottom of the coarse aggregate. However, when using the above method, the placement area of the coarse aggregate needs to be adjusted, otherwise the coarse aggregate may be unstable, resulting in the possibility of position displacement of the coarse aggregate during the test. At the same time, the coarse aggregate may be damaged, resulting in increased production costs.
[0004] Therefore, it is necessary to invent a fixing device for coarse aggregate polishing specimen to solve the above problems. Utility Model Content

[0008] By adopting the above technical solution, the lifting component is fixed to the base plate through the fixing component, and then the position of the coarse aggregate is fixed through the clamping component, so as to facilitate subsequent testing of the coarse aggregate.
[0009] Furthermore, the clamping assembly includes two fixing plates fixedly connected to the top of the bottom plate, a pressing plate is fixedly connected to the top of the fixing plate, and limiting blocks are fixedly connected to the ends of the inner cavities of the two fixing plates.

[0011] Furthermore, the fixing assembly includes a triangular bracket abutting against the top of the base plate, a first bolt is slidably connected inside the triangular part of the triangular bracket, and the first bolt is rotationally connected to the base plate through a thread.

[0013] Furthermore, the lifting assembly includes a sleeve fixedly connected to the top of the tripod bracket, and a sliding rod is slidably connected inside the sleeve.
[0014] By adopting the above technical solution, the height of the pendulum-type friction coefficient tester can be changed by pulling the sliding rod.
[0015] Furthermore, the lifting assembly also includes two clamping blocks abutting against the outer sides of the sleeve and the slide rod, the two clamping blocks are arranged opposite to each other, and two second bolts are rotatably connected to the inside of the clamping blocks through threads.
[0016] By adopting the above technical solution, the second bolt is rotated to loosen the clamping block, thereby changing the positions of the sleeve and the sliding rod.
[0017] Furthermore, the adjustment assembly includes four threaded sleeves fixedly connected to the four corners of the top of the base plate, the inside of the threaded sleeve is connected to a third bolt through threaded rotation, and the bottom of the third bolt is fixedly connected to a decompression pad.
[0018] By adopting the above technical solution, the third bolt is rotated so that the third bolt rotates inside the threaded sleeve, thereby driving the pressure relief pad to move, thereby changing the height of the bottom plate.
[0019] Furthermore, a pendulum-type friction coefficient tester is fixedly connected to the top of the slide rod.
[0020] By adopting the above technical solution, the height of the pendulum-type friction coefficient tester can be changed by a sliding rod.
[0021] Furthermore, the fixing plate and the pressing plate are both made of rubber material.
[0022] By adopting the above technical solution and setting the fixing plate and the pressure plate to be made of rubber material, the possibility of damage to the coarse aggregate when it is clamped is reduced.
[0023] In summary, the present application includes at least one of the following beneficial effects:
[0024] 1. In this application, when it is necessary to use a pendulum-type friction coefficient meter, the tripod bracket can be placed on the base plate first, and then the tripod bracket can be fixed to the base plate by a first bolt, and then the second bolt can be turned to loosen the two clamping blocks, and then the slide bar can be pulled to adjust the height of the pendulum-type friction coefficient meter, and then the second bolt can be turned to fix the position of the slide bar and the sleeve.
