Description

Technical Field

[0001] The utility model relates to the technical field of clamping for rubber material performance detection, in particular to a clamping tooling for detecting the tensile resistance performance of rubber materials. Background Technique

[0002] In the process of rubber material production, the tensile resistance detection of rubber materials is one of the important processing procedures. The tensile resistance detection of rubber materials is an important testing technology. The purpose of the tensile resistance detection of rubber materials is to evaluate the material performance, ensure product quality, optimize the production process, meet industry standards and improve safety. This test is crucial for the healthy development of the rubber industry.

[0003] When detecting the tensile resistance of rubber materials, it is particularly important to fasten and fix them. The traditional clamping tooling only realizes fixation through two groups of clamping plates. However, when the rubber material is fixed by two groups of clamping plates, the rubber material is prone to falling off during the stretching process, and the clamping effect is poor. Therefore, there is an urgent need for a clamping tooling for detecting the tensile resistance performance of rubber materials to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a clamping tooling for detecting the tensile resistance performance of rubber materials is proposed. Its advantage is that it can effectively clamp and fix the rubber material during the tensile detection, ensuring the stability of the rubber material during the tensile detection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A clamping tooling for detecting the tensile resistance performance of rubber materials, including a fixed cylinder. A positioning roller is arranged inside the fixed cylinder. First positioning grooves and second positioning grooves are respectively formed on the circumferential outer wall of the positioning roller. A rubber belt passes through the inside of the first positioning groove and the second positioning groove. A pressing plate is fixedly connected to the circumferential outer wall of the positioning roller. One side of the rubber belt is in contact with the outer wall of one side of the pressing plate. A locking plate is fixedly connected to the circumferential inner wall of the fixed cylinder. A displacement component is arranged inside the fixed cylinder. A through groove is formed on the circumferential outer wall of the fixed cylinder.

[0007] Through the above technical scheme: it can effectively clamp and fix the rubber material during the tensile detection, ensuring the stability of the rubber material during the tensile detection.

[0008] The utility model is further arranged such that a connecting frame is fixedly connected to the circumferential outer wall of the fixed cylinder, and a threaded cylinder is fixedly connected to one side of the connecting frame.

[0009] Through the above technical solution, it is convenient for the subsequent clamping tooling to be firmly connected to the stretching device.

[0010] The present utility model is further configured such that the displacement assembly includes a threaded screw rod rotatably connected to the circumferential outer wall of the fixed cylinder. A threaded sleeve is engaged with the circumferential outer wall of the threaded screw rod. One outer wall of the threaded sleeve is fixedly connected to a reinforcing column, and the reinforcing column is fixedly connected to the positioning roller.

[0011] Through the above technical solution: By rotating the threaded screw rod, the threaded sleeve can be driven to move horizontally, realizing the displacement of the positioning roller, which is convenient for locking and fixing the rubber belt subsequently.

[0012] The present utility model is further configured such that one end of the threaded screw rod is fixedly connected to a turning handle, and the turning handle is located outside the fixed cylinder.

[0013] Through the above technical solution: It is convenient for the staff to rotate the threaded screw rod more easily.

[0016] The present utility model is further configured such that limiting grooves are provided on both outer walls of the sliding seat. A limiting seat is slidably connected inside the limiting groove, and the limiting seat is fixedly connected to the slider.

[0017] Through the above technical solution: By sliding the limiting seat inside the limiting groove, the situation that the slider slides out of the sliding seat can be avoided.

[0018] The present utility model is further configured such that a reinforcing rod is fixedly connected to one inner wall of the connecting frame, and one end of the reinforcing rod away from the connecting frame is fixedly connected to the other outer wall of the connecting frame.

During the displacement of the positioning roller, the pressing plate on one side thereof will also move together until the outer wall of one side of the pressing plate abuts against the outer wall of one side of the locking plate. At this time, the pressing rod on one side of the pressing plate can press the rubber belt into the locking groove on one side of the locking plate, thereby realizing further locking and fixing of the rubber belt.

A locking plate 18 is fixedly connected to the circumferential inner wall of the fixed cylinder 1. A displacement assembly is arranged inside the fixed cylinder 1. A through groove 7 is formed on the circumferential outer wall of the fixed cylinder 1, which can effectively clamp and fix the rubber material during the tensile test, ensuring the stability of the rubber material during the tensile test.

[0038] Specifically, a connecting frame 3 is fixedly connected to the circumferential outer wall of the fixed cylinder 1. A threaded cylinder 4 is fixedly connected to one side of the connecting frame 3, which facilitates the subsequent firm connection of the clamping tool to the tensile device through the threaded cylinder 4.

A threaded sleeve 12 is engaged with the circumferential outer wall of the threaded lead screw 11. A reinforcing column is fixedly connected to the outer wall of one side of the threaded sleeve 12, and the reinforcing column is fixedly connected to the positioning roller 8. By rotating the threaded lead screw 11, the threaded sleeve 12 can be driven to move horizontally, realizing the displacement of the positioning roller 8, which is convenient for subsequent locking and fixing of the rubber belt 2.

[0040] Specifically, a turning handle 6 is fixedly connected to one end of the threaded lead screw 11. The turning handle 6 is located outside the fixed cylinder 1, which is convenient for the staff to rotate the threaded lead screw 11 more easily.
