DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides a polytetrafluoroethylene sealing surface polishing device, comprising a base 1, a polishing component 3 is movably connected to the middle of the upper surface of the base 1, and a movable component 2 is arranged on the upper surface of the base 1;

[0027] The setting of the grinding component 3 makes it easy to place the polytetrafluoroethylene sealing ring, and the setting of the movable component 2 makes it easy to position it. At the same time, the grinding phenomenon is provided, so that the grinding positioning has an integrated feature.

[0028] like Figure 2 - Figure 3 As shown, the movable assembly 2 includes an L-shaped fixing frame 21, the lower end of the L-shaped fixing frame 21 in the vertical direction is fixedly connected to the upper surface of the base 1, a plate is fixedly connected to the lower right side of the L-shaped fixing frame 21 in the vertical direction, a motor 22 is fixedly connected to the right side of the plate, and a gear 23 is fixedly connected to the output shaft of the motor 22, and a connecting rod 27 is movably connected to the front of the upper surface of the L-shaped fixing frame 21 in the horizontal direction, and a thread is set in the middle of the connecting rod 27, and the thread in the middle of the connecting rod 27 is connected to the internal thread of the L-shaped fixing frame 21 The lower end of the connecting rod 27 is movably connected with a sleeve 25, the lower surface of the sleeve 25 is fixedly connected with a grinding disc 24, the front side of the upper surface of the sleeve 25 is fixedly connected with a positioning rod, the outer surface of the positioning rod passes through the interior of the movable component 2 and is slidably connected therebetween, the upper surface of the sleeve 25 is fixedly connected with a spring 26, the inner part of the spring 26 is sleeved below the outer surface of the connecting rod 27, the upper end of the spring 26 is fixedly connected to the lower surface of the L-shaped fixing frame 21 in the horizontal direction, and the lower surface of the grinding disc 24 is provided with a circular opening 241 that communicates with each other from top to bottom;

[0029] When it is needed, the polytetrafluoroethylene sealing ring is placed on the circular seat 31 in the grinding assembly 3, and then the connecting rod 27 is rotated counterclockwise for one circle, so that the threaded L-shaped fixing frame 21 in the middle of the connecting rod 27 is separated horizontally. After separation, the sleeve 25 and the grinding disc 24 are pushed downward by the elastic action of the contracted spring 26. At this time, the spring 26 changes from a contracted state to a raised state, so that the grinding disc 24 contacts the upper surface of the polytetrafluoroethylene sealing ring. Then, the motor 22 is started to drive the gear 23 to make the grinding assembly 3 move, thereby driving the polytetrafluoroethylene sealing ring to rotate, so as to facilitate the grinding of the surface. The machine 22 and the wire are electrically connected to the external power supply. After grinding, the connecting rod 27 is moved upward and rotated clockwise for one circle to drive the sleeve 25 and the grinding disc 24. At this time, the spring 26 changes from the jacking state to the contracted state, and then the polytetrafluoroethylene sealing ring is turned over and the above operation is repeated to grind the other side of the polytetrafluoroethylene sealing ring. The circular opening 241 is set so that when the grinding disc 24 is moved downward, the positioning column 34 in the grinding assembly 3 passes through the circular opening 241 and enters the inside of the sleeve 25. The positioning rod on the sleeve 25 is set to facilitate the position restriction of the grinding disc 24 and the sleeve 25.

[0030] like Figure 4 - Figure 5 As shown, the grinding assembly 3 includes a circular seat 31, a plurality of grooves 32 are provided in an annular array on the upper surface of the circular seat 31, a gear ring 33 is fixedly connected to the outer surface of the circular seat 31, and the outer surface of the gear ring 33 is meshed with the outer surface of the gear 23, a positioning column 34 is provided in the middle of the upper surface of the circular seat 31, a positioning assembly 35 is fixedly connected to the outer surface of the positioning column 34, a fixing bolt 341 is fixedly connected to the middle of the lower surface of the positioning column 34, and the outer surface of the fixing bolt 341 is connected to the inner thread of the circular seat 31, and the positioning assembly 35 includes an elastic rubber ring 351, and a plurality of top tightening blocks 352 are fixedly connected in an annular array on the outer surface of the elastic rubber ring 351, and an inclined surface 354 is provided above the outer surface of the plurality of top tightening blocks 352, and an arc surface 353 is provided below the inclined surface 354;

[0031] After the polytetrafluoroethylene sealing ring is placed on the upper surface of the circular seat 31, the positioning column 34 and the positioning assembly 35 are provided to facilitate the positioning of the polytetrafluoroethylene sealing ring. The friction between the lower surface of the polytetrafluoroethylene sealing ring and the upper surface of the circular seat 31 is increased by the provision of the groove 32, thereby improving the stability effect. After the polytetrafluoroethylene sealing ring is positioned, the motor 22 and the gear 23 cooperate with each other to drive the gear ring 33 and the circular seat 31 to rotate, thereby driving the polytetrafluoroethylene sealing ring to rotate. Due to the contact between the lower surface of the grinding disc 24 and the upper surface of the polytetrafluoroethylene sealing ring, the polytetrafluoroethylene sealing ring is rotated. The surface is in contact with each other, thereby achieving a grinding process. When the polytetrafluoroethylene sealing ring is placed and pressed downward, the inclined surface 354 and the arc surface 353 are set to facilitate the contact between the inner side of the polytetrafluoroethylene sealing ring and the tightening block 352. After the contact, the elastic rubber ring 351 is squeezed to cause deformation and contraction. After the deformation and contraction of the elastic rubber ring 351, the tightening block 352 and the inner side of the polytetrafluoroethylene are closely fitted, thereby strengthening the effect of limiting and fixing its position. When the processing is completed, the polytetrafluoroethylene sealing ring is moved upward by force to complete the disassembly and separate it from the positioning component 35.

[0032] The working principle of the PTFE sealing surface grinding device is described in detail below.

[0033] After placing the polytetrafluoroethylene sealing ring on the upper surface of the circular seat 31, the positioning column 34 and the positioning assembly 35 are arranged to facilitate the positioning of the polytetrafluoroethylene sealing ring. After rotating the connecting rod 27 counterclockwise for one circle, the sleeve 25 and the grinding disc 24 are pushed downward by the elastic action of the contracted spring 26, so that the grinding disc 24 contacts the upper surface of the polytetrafluoroethylene sealing ring. Then, the starting motor 22 drives the gear 23, the gear ring 33 and the circular seat 31 to rotate, thereby driving the polytetrafluoroethylene sealing ring to rotate. Since the lower surface of the grinding disc 24 contacts the upper surface of the polytetrafluoroethylene sealing ring, it is polished.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
