[0002] After the valve sheet is processed, it needs to be polished to remove burrs on the valve sheet and polish the cut position to improve the service life of the valve sheet. The valve sheet and abrasive are put into a finishing machine for polishing. Patent No. 201811047391.7 discloses a drum-type valve sheet finishing machine. At both sides of the top of the bracket, there are support plates. Between the two support plates, a polishing drum with a feeding port is horizontally installed. The polishing drum includes a multi-prismatic barrel with open ends. At both ends of the barrel, there are multi-pyramidal sealing parts integrally formed with the barrel. At the center of the sealing part, there is an end shaft integrally formed with the sealing part and installed on the support plate. One end shaft is connected to the output shaft of the motor. Inside the polishing drum, there is a polishing body assembly installed on the inner wall. It drives the polishing drum to rotate through the motor, and the polishing effect is enhanced by the polishing body assembly arranged on the inner wall. During the rotation of the polishing drum, the valve sheet will rotate following the polishing drum, reducing the polishing effect and the polishing efficiency. Moreover, the valve sheets are stacked together, and it is difficult for the inner-layer valve sheets to collide with the polishing body assembly, resulting in inconsistent polishing effects between the inner and outer valve sheets and uneven polishing of the valve sheets.

DETAILED DESCRIPTION

[0016] 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 explained below in conjunction with specific implementation methods.

[0017] like Figures 1-3 As shown, a swing-type valve plate polishing machine is provided, comprising a base plate 1, a stand 2 is provided on one side of the base plate 1, two swinging bodies 3 are provided on the stand 2, a polishing cylinder 4 is rotatably connected between the swinging bodies 3, the polishing cylinder 4 is a hexagonal prism structure with hexagonal pyramid structures at both ends, and a door body that can be opened and closed is provided on the polishing cylinder 4, the polishing cylinder 4 is placed horizontally, a stand 2 5 is provided on the other side of the base plate 1, a driving wheel 6 is rotatably connected to the stand 2 5, the driving wheel 6 is transmission-connected to the polishing cylinder 4 and drives the polishing cylinder 4 to rotate, the eccentric position of the driving wheel 6 is rotationally connected to the swinging body 3 through a connecting rod 7, a driving motor 8 is installed on the stand 2 5, and the driving motor 8 is connected to the driving wheel 6.

[0018] The valve plate and abrasive to be polished are placed into the polishing cylinder 4, and the driving motor 8 is started. The driving motor 8 drives the driving wheel 6 to rotate, and the driving wheel 6 drives the polishing cylinder 4 to rotate, and the driving wheel 6 drives the swinging body 3 to swing back and forth through the connecting rod 7, so that the polishing cylinder 4 swings while rotating, which increases the probability of collision between the valve plate and the polishing parts in the polishing cylinder 4, and can throw the valve plate of the inner layer of the polishing cylinder 4 to the outer layer, thereby improving the polishing effect and polishing efficiency of the valve plate, and adopts a single power to drive the polishing cylinder 4 to rotate and swing, which reduces the power source, reduces energy expenses, and saves polishing costs.

[0019] like Figure 1 , 3 As shown, two extensions 10 are provided on the stand 2, and a rotating groove 11 is provided on the extension 10. One end of the swing body 3 is placed in the rotating groove 11 and is connected to the extension 10 through a shaft 12. The connection of the shaft 12 allows the swing body 3 to swing back and forth around the rotating groove 11. The finishing cylinder 4 between the swing bodies 3 maintains a balanced state under the action of the stand 1 2, the stand 2 5 and the connecting rod 7, thereby ensuring the stability of the finishing cylinder 4 when rotating and swinging.

[0020] As Figure 1 shown, both ends of the burnishing cylinder body 4 are axially connected to the other end of the swing body 3, and a driven wheel 13 is fixedly connected to the shaft. The driving wheel 6 and the driven wheel 13 are connected by a transmission belt 14. The driving wheel 6 and the driven wheel 13 can be sprockets, and the transmission belt 14 is a chain. The chain meshes with the sprockets. When the driving wheel 6 rotates, the driven wheel 13 is driven to rotate by the chain. The driven wheel 13 is installed at the end of the burnishing cylinder body 4, thereby driving the burnishing cylinder body 4 to rotate.

[0021] As Figure 2 shown, and when the swing body 3 rotates, the transmission belt 14 will change in tightness. A tightness adjustment mechanism 15 is provided on the side of the connecting rod 7. The tightness adjustment mechanism 15 presses down on the transmission belt 14 so that the transmission belt 14 always remains in a taut state. Specifically, the tightness adjustment mechanism 15 includes a limit rod 151 fixedly connected to the side of the connecting rod 7. An outer ring 152 is provided outside the limit rod 151. The outer side surface of the outer ring 152 is in contact with the transmission belt 14. An adjustment wheel 153 is provided between the limit rod 151 and the outer ring 152. A rotating member 154 is provided on one side of the adjustment wheel 153. The rotating member 154 is connected to a rotating member 155 through a connecting belt 156. The rotating member 155 is installed on the side plate 17. The side plate 17 is fixed on the support plate 16. The support plate 16 is fixedly connected to the second vertical frame 5. Engaging teeth are provided on the outer side of the outer ring 152. The engaging teeth mesh with the chain, so that the outer ring 152 and the transmission belt 14 can always remain in an engaged state. The adjustment wheel 153 moves between the outer ring 152 and the limit rod 151, causing the outer ring 152 to change its position relative to the limit rod 151, so that the outer ring 152 follows the tightness adjustment of the transmission belt 14. And the connecting belt 156 between the rotating member 154 and the rotating member 155 is an elastic belt. The connecting belt 156 is a closed belt and is sleeved between the rotating member 154 and the rotating member 155. Both the rotating member 154 and the rotating member 155 are bearings and shallow grooves are provided on the outer side walls to facilitate the limitation of the connecting belt 156. At the same time, in order to ensure that the adjustment wheel 153 can be closely limited to the limit rod 151 and the outer ring 152, a first annular groove 157 is provided on the outer side wall of the limit rod 151, and a second annular groove 158 is provided on the inner side wall of the outer ring 152. An annular protrusion 159 is provided on the outer side wall of the adjustment wheel 153. The annular protrusion 159 is placed in the first annular groove 157 and the second annular groove 158 and rotates around the first annular groove 157 and the second annular groove 158. The annular protrusion 159 is used to limit the adjustment wheel 153 by matching with the first annular groove 157 and the second annular groove 158. And a limit disc 1510 is fixedly connected to the end face of the limit rod 151 through a pin. The inner side surface of the limit disc 1510 is in contact with the same outer side surface of the outer ring 152 and the adjustment wheel 153, further limiting the adjustment wheel 153.

[0022] Its working principle is as follows: The valve plate and abrasive are placed into the finishing cylinder body 4. The driving motor 8 is started, and the driving motor 8 drives the driving wheel 6 to rotate. The driving wheel 6 drives the driven wheel 13 to rotate through the transmission belt 14, thereby driving the finishing cylinder body 4 to rotate. Moreover, the connecting rod 7 connected to the eccentric position on the side of the driving wheel 6 drives the swing body 3 to swing reciprocally, realizing the rotation and swing of the finishing cylinder body 4. And the outer ring 152 is pressed against the transmission belt 14 under the action of the adjusting wheel 153, pressing down on the transmission belt 14 so that the transmission belt 14 always remains in a taut state, thus enabling the driving wheel 6 and the driven wheel 13 to always be in a transmission state, ensuring the stability of the overall operation.
