Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, and particularly relates to a specimen clamping mechanism suitable for a rubber bearing compression-shear test equipment. Background Technique

[0002] In the rubber bearing compression-shear test, the specimen usually refers to the rubber bearing itself that needs to be subjected to the compression-shear test. Rubber bearings, especially those used for structural isolation, such as lead-core rubber bearings and high-damping rubber bearings, are the main objects of the test. Under the action of external forces such as earthquakes, these bearings absorb and disperse energy by generating horizontal deformation, thereby protecting the safety of building structures.

[0003] The specimen clamping mechanism plays a crucial role in the rubber bearing compression-shear test. It is responsible for stably clamping the rubber bearing to ensure that the bearing can be subjected to pressure and shear forces in a predetermined manner during the test. The traditional fixing method is to manually clamp and fix it by the staff, which is inefficient and increases the burden on the staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide a specimen clamping mechanism suitable for a rubber bearing compression-shear test equipment to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A specimen clamping mechanism suitable for a rubber bearing compression-shear test equipment, including a workbench, a fixed seat is fixedly connected to the top of the workbench, a sliding and moving mechanism is arranged in the fixed seat, and a spring-back mechanism is arranged in the fixed seat;

[0006] The sliding and moving mechanism includes a sliding component and a moving component. The sliding component is arranged on the front and back sides inside the fixed seat, and the moving component is arranged on the front side of the top of the workbench;

[0007] The sliding component includes a first sliding groove, the first sliding groove is opened on the left side inside the fixed seat, a first inclined block slides back and forth in the first sliding groove, a second sliding groove is opened on the right side inside the first sliding groove, a second inclined block slides in the second sliding groove, the right side of the top of the second inclined block is fixedly connected with a sliding block, the top of the sliding block is fixedly connected with a clamping block, and a third sliding groove is opened on the left side of the top of the fixed seat.

[0008] Preferably, the inclined surface of the first inclined block corresponds to the inclined surface of the second inclined block, the front and back sides of the sliding block slide in the third sliding groove, and there are two groups of the sliding components, which are symmetrically arranged on the left and right sides inside the fixed seat.

[0009] Preferably, the moving component includes a fixed sleeve frame fixedly connected to the front of the top of the workbench. A motor is fixedly connected inside the fixed sleeve frame. The output end of the motor is fixedly connected with a screw rod. A sliding frame is threadedly connected to the surface of the screw rod. A bearing is fixedly connected to the front of the fixed seat.

[0010] Preferably, grooves matching the sliding frame are formed on the left and right sides of the front of the fixed seat, and the surface of the sliding frame penetrates and is slidably connected inside the grooves. Both ends of the sliding frame are fixedly connected to the front of the first inclined block.

[0011] Preferably, the rear end of the surface of the screw rod is fixedly connected to the inner ring of the bearing.

[0014] Compared with the prior art, the present utility model provides a specimen clamping mechanism applicable to a rubber bearing compression-shear test device, having the following beneficial effects:

[0015] 1. For the specimen clamping mechanism applicable to the rubber bearing compression-shear test device, by sliding the moving mechanism, the specimen is placed on the fixed seat and located between the two clamping blocks. Then, the motor is started to rotate the screw rod. The rotation of the screw rod will cause the sliding frame to move backward. The sliding frame drives the first inclined block to move backward in the first chute. During the backward movement of the first inclined block, it will squeeze the second inclined block, causing the two second inclined blocks to move towards each other, thereby driving the two clamping blocks to move towards each other to clamp and fix the specimen. This fixing method is simple and convenient, and does not require manual fixing, which can effectively save the physical strength of the staff.

[0016] 2. For the specimen clamping mechanism applicable to the rubber bearing compression-shear test device, through the rebounding mechanism, after the specimen test is completed, the screw rod is reversed by the motor, so that the sliding frame moves forward, and thus the first inclined block moves forward. At this time, affected by the spring force, the second inclined blocks will move in the opposite direction towards each other, so that the two clamping blocks move in the opposite direction towards each other, thereby releasing the clamping and fixing of the specimen.
