DETAILED DESCRIPTION

[0024] The specific embodiments of the utility model are further described below in combination with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0025] Embodiment one

[0026] Please refer to Figures 1-4 , a side polishing device of flange gasket, including main body frame 1, rotating platform 2 is arranged below in the inside of main body frame 1, positioning assembly 3 is arranged between rotating platform 2 and the upper main body frame 1 thereof, the positioning assembly 3 includes movable rod 31 connected with telescopic cylinder, two round plate fixing pieces 32 are slidably connected below movable rod 31 through sleeve, and round plate fixing piece 32 is connected to the upper portion of main body frame 1 through first spring 35. The positioning assembly 3 is opposite to the rotating platform, and polishing device 4 is further arranged on the main body frame between the positioning assembly 3 and the rotating platform 2, and the rotating platform 2 is connected with telescopic cylinder, and it needs to be explained that movable rod 31 can rotate, and only the up-and-down movement is driven by telescopic cylinder.

[0027] Adjusting assembly 5 is further arranged between round plate fixing piece 32 and movable rod 31, adjusting assembly 5 includes fixing block 51 and adjusting rod 55 arranged in round plate fixing piece 32, adjusting rod 55 is provided with positioning hole 56, fixing block 51 is provided with through slot 52, limiting hole 53 is arranged in through slot 52, second spring 57 connected small ball 54 is arranged in limiting hole 53, small ball 54 partially leaks out of limiting hole 53, and the small ball that leaks out of limiting hole 53 is adapted to positioning hole 56. Adapt to different specifications of flange gasket.

[0028] A lower pressing fixed part 33 is arranged below the movable rod 31, and a buffer pad 34 is arranged below the lower pressing fixed part 33. The cross section of the circular plate fixing part 32 is designed such that the cavity between the two circular plate fixing parts 32 is in the shape of a circular truncated cone with a narrow top and a wide bottom. The inner surface of the circular plate fixing part is also provided with a buffer pad 34. The buffer pad 34 is preferably made of sponge material, and more preferably made of latex material. The buffer pad 34 is mainly arranged to prevent secondary damage to the flange gasket during machining. In addition, the buffer pad 34 can also alleviate the damage to the surface structure of the flange gasket caused by the relative rotation friction between the circular plate fixing part 32, the lower pressing fixed part 33 and the flange gasket.

[0029] In order to simplify the structure and improve the polishing effect of the polishing device on the burrs at the edge of the flange gasket, the polishing device 4 is a polishing cloth wheel. The surface of the polishing cloth wheel is a flexible polishing cloth with elasticity. Since the burrs at the edge of the flange gasket formed by the mold pressing are not obvious, the polishing device is mainly used for the high-precision requirement of the electronic-grade chemical pipeline, and the polishing thickness is about tens of microns. Therefore, the polishing device does not need to move along the radial direction of the rotating platform 2, but can be polished by the elastic effect of the polishing cloth wheel. A rotating shaft is arranged below the rotating platform 2, and the rotating shaft is connected to the polishing device 4 through a first gear 6 and a rotating shaft 62. By adjusting the gear transmission ratio, the polishing cloth wheel can be driven by a single motor, and the polishing cloth wheel can rotate.

[0030] Please refer to Figure 5 The rotating shaft 62 of the polishing cloth wheel is fixedly provided with a second gear 61, the second gear 61 is engaged with the first gear 6, and the polishing cloth wheel is driven to rotate by the motor main shaft connected to the rotating platform 2, thereby reducing the unnecessary setting of the motor.

[0031] Please refer to Figure 7 The workpiece polished by the utility model is a circular four-fluoride gasket 7 with screw holes.

[0032] Working principle:

[0033] First, the flange gasket is placed on the rotating platform, the buffer pad of the lower pressing fixed part is contacted with the flange gasket on the rotating platform, the movable rod is manually downwardly buckled with the flange gasket, the flange gasket is adjusted to be located at the center position of the rotating platform, the flange gasket is pressed tightly by the lower pressing fixed part, the circular plate fixing part is reset due to the fact that one end of the first spring is connected to the main frame, and at this time, the rotating platform rotates, the flange gasket is tangent to the polishing cloth wheel, and the polishing work is completed. The movable rod is a sleeve, the sleeve is connected with the telescopic cylinder, and the sleeve can rotate with the rotating platform to avoid damage to the flange gasket caused by the relative rotation between the rotating platform and the movable rod.

[0034] When adjusting the gaskets of different sizes, the sliding block is slid, and the force between the ball and the adjusting rod is forced, so that the ball is forced into the limiting hole of the fixed block against the elastic force of the second spring. When the adjusting rod and the ball move to the next positioning hole, the ball is clamped into the new positioning hole under the action of the elastic force of the second spring. Adjusting all the above structures can realize the polishing requirements of different sizes of gaskets.

[0035] Embodiment two

[0036] Please refer to Figure 6 Different from embodiment one, three round plate positioning members are arranged in embodiment two, and the adjusting assembly is arranged correspondingly. The arrangement of the three round plate positioning members makes the round plate fixing member have three tangent points for the smaller size gaskets after the adjusting assembly is adjusted, which is beneficial to the positioning of the gaskets.

[0037] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, some improvements and refinements can be made, and these improvements and refinements should be regarded as the protection scope of the present application.
