Description

Technical Field

[0002] Ceramic rod is a rod-shaped product made of ceramic material. Ceramic rod is a specially manufactured welding rod-shaped flame spray material in combination with a ceramic rod flame spray gun. It has the characteristics of high temperature resistance, wear resistance, insulation, light weight, reduced raw material cost, energy saving, and easy operation.

[0003] Since the ceramic rod will bend and deform to a certain extent after high-temperature sintering, subsequent mechanical processing is required to ensure that its verticality meets the required requirements, and a ceramic rod fixing fixture is often required.

The clamping pressure between the ceramic rods will cause the ceramic rods to rub against each other, which will then cause damage to the ceramic rods, affecting the quality of ceramic rod production. Therefore, we need a ceramic rod fixing clamp. Utility Model Content

[0029] Through the above technical scheme, the first motor 401 is started to drive the screw rod 402 to rotate and the movable plate 403 to move at the same time. Since the threads on both sides of the screw rod 402 rotate in opposite directions and the two movable plates 403 are symmetrically arranged on both sides of the screw rod 402, the two movable plates 403 are relatively moved on the screw rod 402, and then the two movable plates 404 rotate in the opposite direction to drive the lifting plate 3 to move up and down. The lifting plate 3 clamps the ceramic rod downward through the outer clamp plate 406, and the inner clamp plate 408 arranged in the outer clamp plate 406 moves elastically through the elastic force of the spring 407, which can buffer the applied pressure in the process of clamping and fixing to prevent the ceramic rod from being damaged by excessive pressure.

[0030] Specifically, a slide groove 5 is provided on one side of the support plate 2 , and a lower clamping plate 6 is fixedly connected to the top of the base 1 .

[0031] Through the above technical scheme, it is convenient for the lifting plate 3 to slide through the slide groove 5 during the lifting process, thereby improving the lifting stability of the lifting plate 3, and the lower splint 6 cooperates with the top outer splint 406 to wrap the ceramic rod, and a protective pad is provided on the inner wall of the lower splint 6 to avoid scratching the ceramic rod.

[0032] Specifically, the first motor 401 forms a moving structure with the moving plate 403 through the screw rod 402 , and the external thread of the screw rod 402 matches the internal thread of the moving plate 403 , and the threads on both sides of the screw rod 402 have opposite rotation directions.

[0033] Through the above technical solution, it is convenient to start the first motor 401 to drive the screw rod 402 to rotate so that the movable plate 403 moves. Because the threads on both sides of the screw rod 402 rotate in opposite directions, the two movable plates 403 move in opposite directions, achieving the effect of reverse movement of the movable plate 403.

[0034] Specifically, the moving plate 403 forms a lifting structure with the lifting plate 3 through the movable plate 404 , and the number of movable plates 404 is two, and the movable plate 404 is arranged between the moving plate 403 and the lifting plate 3 .

[0035] The above technical solution facilitates the lifting plate 3 to move up and down by rotating the movable plate 404 during the reverse movement of the two movable plates 403 .

[0036] Specifically, the lifting plate 3 forms a fixed structure with the outer clamping plate 406 through the connecting rod 405, and the connecting rod 405 is arranged between the lifting plate 3 and the outer clamping plate 406. The outer clamping plate 406 forms an elastic structure with the inner clamping plate 408 through the spring 407, and the number of the springs 407 is multiple.

[0038] Specifically, the second motor 701 forms a moving structure through the screw rod 702 and the moving block 703 , and the external thread of the screw rod 702 matches the internal thread of the moving block 703 .

[0039] Through the above technical solution, it is convenient to start the second motor 701 to drive the screw 702 to rotate and drive the moving block 703 to move at the same time, thereby achieving the effect of moving the moving block 703.

[0040] Specifically, the moving block 703 forms a fixed structure through the slide plate 704 and the receiving plate 705 , and the slide plate 704 is arranged between the moving block 703 and the receiving plate 705 .

[0041] Through the above technical solution, it is convenient for the moving block 703 to drive the receiving plate 705 on the slide plate 704 to move, and the distance between them can be adjusted according to the length of different ceramic rods. The receiving plate 705 can receive both ends of the ceramic rod to avoid clamping the ceramic rod only at one place. The two sides of the ceramic rod may tilt, which plays an auxiliary role in the clamping and fixation of the ceramic rod.

[0042] Working principle: When using the ceramic rod fixing fixture, first, when clamping and fixing the ceramic rod, first place the ceramic rod on the lower clamping plate 6, and then start the first motor 401. The first motor 401 drives the screw rod 402 to rotate, so that the movable plate 403 moves. Because the threads on both sides of the screw rod 402 rotate in opposite directions, the two movable plates 403 move in opposite directions. Then, during the reverse movement of the two movable plates 403, the movable plate 404 rotates, so that the lifting plate 3 moves downward. The lifting plate 3 moves downward to clamp and fix the ceramic rod through the outer clamping plate 406, and when the ceramic rod contacts the inner clamping plate 408, the inner clamping plate 408 The spring 407 can perform elastic movement to buffer the pressure applied to the ceramic rod to prevent damage to the ceramic rod caused by excessive pressure, and then start the second motor 701. The second motor 701 drives the screw 702 to rotate and drives the moving block 703 to move. The moving block 703 drives the receiving plate 705 on the slide plate 704 to move. The distance between the two plates can be adjusted according to the length of different ceramic rods, and the two ends of the ceramic rod can be supported to prevent the center of gravity from being unstable and possibly tilting, thereby playing an auxiliary role in the clamping and fixing of the ceramic rod. This completes all the work. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
