[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the polishing belt is rotated by the rotation of the gear liner, and the watch gear fixed on the outer periphery of the supporting vertical rod is driven to rotate by the meshing action of the gear liner, and the supporting vertical rod is further driven to rotate, so that the teeth of the gear liner drive the polishing belt to rotate and continuously contact and rub with the teeth of the watch gear, thereby polishing the watch gear. During this period, the rotation of the shaft sleeve will also drive the reciprocating cam to rotate, and under the path cooperation of the positioning pin and the surface groove wall of the reciprocating cam, the shaft sleeve is further made to reciprocate up and down while rotating, thereby driving the gear liner and the polishing belt to continuously swing up and down while rotating, which can improve the polishing effect of the watch gear.

[0019] 2. In the present invention, while the watch gear is driven to rotate by the gear liner, the supporting vertical rod drives the swash plate to rotate accordingly. Since the swash plate is inclined, the swash plate pushes the sliding balls and the sliding rods upwards cyclically and one by one during the rotation. The sliding balls pushed upwards then drive the top springs connected to them to compress and accumulate force, thereby exerting a downward pressure on the swash plate, causing the swash plate to generate a certain range of resistance during the rotation process, so that the gear liner needs to move when driving the watch gear to rotate. That is to say, there is a certain contact force between the watch gear and the polishing belt when it rotates, so as to ensure sufficient contact between the polishing belt and the teeth of the watch gear to ensure the polishing quality.

[0020] 3. In the present invention, the gear lining and the polishing belt wrapped around the outer periphery of the gear lining are driven to rotate together by the rotation of the shaft sleeve. The rotation of the gear lining also drives the rotation of the adsorption frame. The rotation of the adsorption frame drives multiple negative pressure cylinders, negative pressure pistons and counterweight balls to rotate together. The rotation of the negative pressure piston generates centrifugal force, causing the negative pressure piston to move along the inner wall of the negative pressure cylinder away from the center of the adsorption frame, causing negative pressure to be generated inside the negative pressure cylinder. The negative pressure is transmitted to the inside of the adsorption chamber through the adsorption frame and the air suction groove, and the polishing belt is firmly adsorbed on the outer periphery of the gear lining through multiple adsorption holes to ensure the stable strength of the polishing belt.

[0036] An insert shaft 207 is slidably mounted inside the shaft sleeve 202, and a plurality of key blocks 208 distributed at equal angles are fixedly mounted on the outer wall of the insert shaft 207. A plurality of key slots 209 distributed at equal angles are opened on the inner wall of the shaft sleeve 202. The specifications of the key blocks 208 match those of the key slots 209, and the key blocks 208 are slidably located inside the key slots 209.

[0037] A servo motor 2010 is fixedly mounted on one side of the side plate 102 away from the top plate 103, a driving gear 2011 is fixedly mounted on the output shaft of the servo motor 2010, a driven gear 2012 is meshed with the periphery of the driving gear 2011, and the inner wall of the driven gear 2012 is fixedly connected to the upper part of the outer wall of the insertion shaft 207;

[0038] Specifically, the present embodiment is as follows: first, the fastening nut 303 is unscrewed, and then the watch gear is sleeved on the outer wall of the holding vertical rod 301 from the bottom of the holding vertical rod 301, and then the fastening nut 303 is screwed on the lower part of the outer wall of the holding vertical rod 301 again by screwing, and the upper and lower clamping forces of the pressure plate 302 and the fastening nut 303 are cooperated to fix the watch gear on the periphery of the holding vertical rod 301, and then the polishing belt 204 is covered on the periphery of the gear lining 203, and the servo motor 2010 is started. After the servo motor 2010 is started, the driving gear 211 is driven to rotate, and the driving gear 211 rotates through the driven gear 2 012 drives the plug shaft 207 to rotate together. The rotation of the plug shaft 207 drives the sleeve 202 to rotate along the two adapter seats 201 under the torque limiting action of the key block 208 and the keyway 209. The rotation of the sleeve 202 further drives the gear lining 203 and the polishing belt 204 wrapped around the outer periphery of the gear lining 203 to rotate together. At the same time, the rotation of the gear lining 203 drives the polishing belt 204 to rotate together, and the watch gear is driven to rotate under the meshing action of the gear lining 203 and the watch gear fixed on the outer periphery of the support vertical rod 301, and further drives the support vertical rod 301 to rotate, so that the teeth of the gear lining 203 drive the polishing belt 204 to rotate. The light belt 204 rotates and continuously contacts and rubs against the teeth of the watch gear, thereby polishing the watch gear. During this period, the rotation of the shaft sleeve 202 will also drive the reciprocating cam 205 to rotate, and under the path cooperation of the positioning pin 206 and the surface groove wall of the reciprocating cam 205, the shaft sleeve 202 is further made to reciprocate up and down while rotating, thereby driving the gear liner 203 and the polishing belt 204 to continuously swing up and down while rotating, which can improve the polishing effect of the watch gear. During the period when the gear liner 203 drives the watch gear to rotate, the support vertical rod 301 drives the inclined plate 304 to rotate accordingly. Since the inclined plate 304 is The inclined distribution causes the inclined plate 304 to push the sliding ball 3010 and the sliding rod 309 upwards cyclically and one by one during the rotation. The sliding ball 3010 pushed upward then drives the top spring 3011 connected to it to compress and accumulate force, thereby causing a downward pressure on the inclined plate 304, causing the inclined plate 304 to generate a certain range of resistance during the rotation process, so that the gear lining 203 needs to move when driving the watch gear to rotate. In other words, there is a certain contact force between the watch gear and the polishing belt 204 when rotating, so as to ensure sufficient contact between the polishing belt 204 and the teeth of the watch gear to ensure the polishing quality. Embodiment 2

[0039] The adsorption component includes an adsorption chamber 2014 opened at the top of the gear liner 203, and the outer wall of the adsorption chamber 2014 is penetrated by a plurality of adsorption holes 2013 distributed at equal angles, and the adsorption holes 2013 are all located between two adjacent teeth of the gear liner 203, and the adsorption holes 2013 are divided into upper and lower multi-layer arrangements, and an adsorption circular frame 2015 is fixedly installed on the top of the gear liner 203, and an air suction groove 2016 is opened at the bottom of the adsorption circular frame 2015, and the air suction groove 2016 coincides with the adsorption chamber 2014, and a plurality of negative pressure cylinders 2017 distributed at equal angles are fixedly installed on the side wall of the adsorption circular frame 2015, and a negative pressure piston 2018 is slidably installed on the inner wall of the negative pressure cylinder 2017, and a counterweight ball 221 is fixedly installed on the end of the telescopic rod 2019 away from the negative pressure piston 2018;

[0040] Specifically, the present embodiment drives the gear liner 203 and the polishing belt 204 wrapped around the outer periphery of the gear liner 203 to rotate together through the rotation of the shaft sleeve 202. The rotation of the gear liner 203 also drives the adsorption frame 2015 to rotate. The rotation of the adsorption frame 2015 drives multiple negative pressure cylinders 2017, negative pressure pistons 2018 and counterweight balls 2021 to rotate together. The rotation of the negative pressure piston 2018 generates centrifugal force, causing the negative pressure piston 2018 to move along the inner wall of the negative pressure cylinder 2017 in a direction away from the center of the adsorption frame 2015, causing negative pressure to be generated inside the negative pressure cylinder 2017. The negative pressure is transmitted to the interior of the adsorption chamber 2014 through the adsorption frame 2015 and the air suction groove 2016, and the polishing belt 204 is firmly adsorbed on the outer periphery of the gear liner 203 through multiple adsorption holes 2013 to ensure the stability and strength of the polishing belt 204.

[0041] Furthermore, a telescopic rod 2019 is fixedly installed in the middle of one side of the negative pressure piston 2018 away from the center of the adsorption circular frame 2015, and a return spring 2020 is sleeved on the outer periphery of the telescopic rod 2019. The return spring 2020 is fixedly installed between the negative pressure piston 2018 and the inner wall of one end of the negative pressure cylinder 2017. When the negative pressure piston 2018 is subjected to the centrifugal force and moves along the inside of the negative pressure cylinder 2017, it will cause a compression effect on the return spring 2020, and then after the polishing is completed, the servo motor 20 is turned off. 10. The shaft sleeve 202 stops rotating, and the adsorption circle frame 2015 and the negative pressure cylinder 2017 stop rotating, causing the centrifugal force on the negative pressure piston 2018 to disappear, and the elastic force of the reset spring 2020 is released, pushing the negative pressure piston 2018 to complete the reset effect. According to the centrifugal force formula F=mv2 / rm, when the speed is constant, the greater the weight, the stronger the centrifugal force can be obtained. Therefore, by adding a counterweight ball 2021, the centrifugal force of the negative pressure piston 2018 can be enhanced, so that the negative pressure piston 2018 can move better. Embodiment 3

[0042] Two support rods 104 are fixedly installed at the bottom of the top plate 103. The two support rods 104 are located at the periphery of the vertical support rod 301, and the two support rods 104 are symmetrically distributed about the center of the vertical support rod 301. The bottoms of the two support rods 104 are commonly connected with an adapter plate 105. The vertical support rod 301 passes through the adapter plate 105, and the vertical support rod 301 and the adapter plate 105 are rotatably connected through a bearing;

[0043] Specifically, the present embodiment provides two support rods 104 for fixing the adapter plate 105, and further ensures the rotation stability of the mounting vertical rod 301 under the lateral support of the mounting vertical rod 301 by the adapter plate 105, so as to ensure that the bottom of the mounting vertical rod 301 does not easily swing sideways when the mounting vertical rod 301 rotates.

[0044] When the precision polishing device for alloy parts of a watch of the present invention is in operation, the fastening nut 303 is firstly screwed off, and then the watch gear is sleeved on the outer wall of the support vertical rod 301 from the bottom of the support vertical rod 301, and then the fastening nut 303 is screwed on the lower part of the outer wall of the support vertical rod 301 again by screwing, and the upper and lower clamping forces of the pressure plate 302 and the fastening nut 303 are cooperated to fix the watch gear on the periphery of the support vertical rod 301;

[0045] Then, the polishing belt 204 is wrapped around the periphery of the gear liner 203, and the servo motor 2010 is started. After the servo motor 2010 is started, the driving gear 2011 is driven to rotate. The driving gear 2011 rotates through the driven gear 2012 to drive the plug shaft 207 to rotate together. The plug shaft 207 rotates through the torque limiting action of the key block 208 and the keyway 209 to drive the shaft sleeve 202 to rotate along the two adapter seats 201. The rotation of the shaft sleeve 202 further drives the gear liner 203 and the polishing belt 204 wrapped around the periphery of the gear liner 203 to rotate together. The rotation of the gear liner 203 also drives the adsorption circular frame 2015 to rotate, and the adsorption circular frame 2015 is sucked. The rotation of the attachment frame 2015 drives the multiple negative pressure cylinders 2017, the negative pressure piston 2018 and the counterweight ball 2021 to rotate together. The rotation of the negative pressure piston 2018 generates centrifugal force, causing the negative pressure piston 2018 to move along the inner wall of the negative pressure cylinder 2017 in a direction away from the center of the adsorption frame 2015, causing negative pressure to be generated inside the negative pressure cylinder 2017. The negative pressure is transmitted to the inside of the adsorption chamber 2014 through the adsorption frame 2015 and the air suction groove 2016, and the polishing belt 204 is firmly adsorbed on the periphery of the gear liner 203 through the multiple adsorption holes 2013 to ensure the stability and strength of the polishing belt 204;

[0046] At the same time, the rotation of the gear liner 203 drives the polishing belt 204 to rotate together, and the meshing action of the gear liner 203 and the watch gear fixed on the outer periphery of the support vertical rod 301 drives the watch gear to rotate, and further drives the support vertical rod 301 to rotate, so that the teeth of the gear liner 203 drive the polishing belt 204 to rotate and continuously contact and rub with the teeth of the watch gear, thereby polishing the watch gear. During this period, the rotation of the shaft sleeve 202 also drives the reciprocating cam 205 to rotate, and under the path cooperation of the positioning pin 206 and the surface groove wall of the reciprocating cam 205, the shaft sleeve 202 is further made to reciprocate up and down while rotating, thereby driving the gear liner 203 and the polishing belt 204 to continuously swing up and down while rotating, which can improve the polishing effect of the watch gear.

[0047] When the gear lining 203 drives the watch gear to rotate, the supporting vertical rod 301 also drives the swash plate 304 to rotate. Since the swash plate 304 is inclined, the swash plate 304 pushes the sliding ball 3010 and the sliding rod 309 upward cyclically and one by one during the rotation. The sliding ball 3010 pushed upward drives the top spring 3011 connected to it to compress and accumulate force, thereby causing a downward pressure on the swash plate 304, causing the swash plate 304 to generate a certain range of resistance during the rotation process, so that the gear lining 203 needs to move when driving the watch gear to rotate. That is to say, there is a certain contact force between the watch gear and the polishing belt 204 when it rotates, so as to ensure that the polishing belt 204 is in full contact with the teeth of the watch gear to ensure the polishing quality.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
