A first slide 103 is slidably provided inside the first sliding groove 102. The first slide 103 can move back and forth along the direction of the first sliding groove 102. A second sliding groove 104 is symmetrically provided on the upper surface of the first slide 103. A second slide 105 is slidably provided inside the second sliding groove 104. The second slide 105 can move back and forth along the direction of the second sliding groove 10 4 moves back and forth, and also includes a driving mechanism 200, a clamping mechanism 300 and a grinding mechanism 400. The driving mechanism 200 is arranged on one side of the first slide 103, and is used to drive the valve stem to move so as to correspond to the grinding wheel 404. The clamping mechanism 300 is arranged on the upper end of the second slide 105 to fix the position of the valve stem and avoid the phenomenon of deviation during the processing. The grinding mechanism 400 is arranged on one side of the first slide 102. Before the valve stem end chamfering device is used, first check whether the device can be used normally, and then adjust the clamping mechanism 300 so that the device enters the standby state;

[0031] The driving mechanism 200 includes an electric push rod 201 fixedly mounted on the upper end of the first slide 103. The output end of the electric push rod 201 is fixedly connected to the second slide 105. When the electric push rod 201 is started, the second slide 105 is driven to move, so that different valve stems can correspond to the positions of the grinding wheel 404. A screw 202 is fixedly provided on the end of the first slide 103 away from the grinding mechanism 400. The outer thread of the screw 202 is connected to a threaded sleeve 203.

The threaded sleeve 203 is driven to rotate by the first motor, which can drive the screw 202 to move left and right, thereby driving the first slide 103 to move, so as to facilitate the chamfering operation of the valve stem.

[0032] Among them Figure 3As shown, the clamping mechanism 300 includes a limit plate 301, and scale lines are set on the surfaces of the limit plate 301 and the L-shaped plate 303. A number of grooves 302 are evenly opened on the surface of the limit plate 301, and a spring assembly is set inside the groove 302 to facilitate clamping on both sides of the valve stem. An L-shaped plate 303 is fixedly installed on one side of the groove 302, and the internal thread of the top plate of the L-shaped plate 303 is provided with a first threaded rod 304. The lower end of the first threaded rod 304 is rotatably connected to a pressure plate 305. The shape and specifications of the pressure plate 305 are adapted to the shape of the valve stem.

[0035] Among them Figure 2 As shown, a moving groove 106 adapted to the water collecting box 402 is provided on one side of the first slide 103 close to the water collecting box 402 to avoid interference with the moving operation of the first slide 103 and ensure the overall practicality of the device.

[0036] Among them Figure 3 As shown, a guide rod is also fixedly installed on the upper surface of the pressure plate 305, one end of the guide rod passes through the L-shaped plate 303 and is fixedly connected to the limit block. The guide rod is slidably connected to the L-shaped plate 303, guiding the movement operation of the pressure plate 305, thereby enabling the pressure plate 305 to move smoothly above the valve stem.

[0037] Among them Figure 5 As shown, a filter plate 406 is provided inside the water collection box 402. The filter plate 406 and the water collection box 402 can be set to a detachable connection for easy replacement. Dust and debris are driven by the water source to flow into the water collection box 402. The filter plate 406 collects and filters the polished debris, so that the debris can be stored above the filter plate 406, and can smoothly filter the wastewater after dust reduction and cooling, so that the wastewater can be filtered, that is, the water source can be recycled. A water pump is provided on one side of the water collection box 402. The water pump is a common pump body in this field. The structure can prevent the internal structure from being damaged by smaller debris. The water pump is arranged below the filter plate 406. The output end of the water pump is fixedly connected to the water inlet pipe 407. A valve is provided on the outside of the water inlet pipe 407 to facilitate control of the water flow rate and the switching status. One end of the water inlet pipe 407 extends to the inside of the protective cover 405 and is fixedly connected to a nozzle 408. The nozzle 408 is used to cool and reduce dust on the grinding wheel 404 during operation. One side of the nozzle 408 can be set to a universal tube structure to facilitate selection of a suitable water spraying position according to demand.

[0038] Example 2

[0039] The difference from Example 1 is that Figure 6 and Figure 7 As shown, the clamping mechanism 300 also includes a plurality of second threaded rods 307 threadedly connected to the limit plate 301, and one end of the second threaded rod 307 is rotatably connected to the side clamping plate 308, and one side of the side clamping plate 308 is provided with anti-slip grooves. The side clamping plate 308 is slidably connected to the bottom wall of the groove 302. The user rotates the second threaded rod 307, thereby driving the side clamping plate 308 to move, and then adapting to valve stems of different lengths. The outer diameter of the side clamping plate 308 is smaller than the distance between the two clamping plates 306. At this time, the two clamping plates 306 are in the initial state and are not subjected to compression force.

[0040] During use, the staff fixes several valve stems inside the groove 302, rotates the first threaded rod 304 and the second threaded rod 307, so that the clamp 306 and the side clamp 308 can fix the valve stem position. When chamfering processing is required, the first motor can drive the threaded sleeve 203 to rotate, and then drive the screw 202 and the first slide 103 to move, and then push the valve stem to be processed to the position of the grinding wheel 404. When one of the valve stems is polished, the first motor can drive the threaded sleeve 203 to reverse, and then drive the screw 202 and the first slide 103 to return to their original position. At this time, the electric push rod 201 starts, driving the second slide 105 to move, so that the center of the next valve stem corresponds to the position of the grinding wheel 404, and then repeats the above-mentioned rotation operation of the first motor, thereby realizing the automated chamfering processing operation of the device.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
