[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3, the utility model provides an embodiment: a pulley processing pusher device, including a base 1, a clamping mechanism 2 is arranged inside the base 1, both sides of the inner front wall of the base 1 are rotatably connected with a rotating shaft 3, the rear ends of the two rotating shafts 3 are rotatably connected to the inner rear wall of the base 1, a servo motor 2 5 is fixedly connected to one side of the front wall of the base 1, the output end of the servo motor 2 5 passes through the base 1 and is fixedly connected to one side of the rotating shaft 3, the outer periphery of the two rotating shafts 3 are sleeved with a transmission belt 4, a connecting disk 7 is arranged on the upper side of the base 1, and a connecting rod 1 8 and a connecting rod 2 9 are penetrated in the middle of both sides of the connecting disk 7, the connecting rod 1 8 and the connecting rod 2 9 are rotatably connected, one end of the connecting rod 1 8 and the connecting rod 2 9 are rotatably connected with a connecting block 10, and the two connecting blocks 10 are rotatably connected with a clamping plate 11 at the close ends; the front and rear walls of the base 1 are slidably connected with a supporting plate 16, and a locking member 15 is threadedly connected to one side of the front wall of the supporting plate 16, and the rear end of the locking member 15 passes through the base 1;

[0030] Specifically, when it is necessary to adjust the positions of both sides of the pulley to be processed, the locking piece 15 can be rotated first to withdraw it and cancel the limit of the base 1 and the support plate 16, so that the base 1 can be pushed to drive the pulley to move. When the pulley and the base 1 are moved to a suitable position, the locking piece 15 can be inserted again to fix them. After the position is adjusted, the staff can pull one end of the connecting rod 1 8 and the connecting rod 2 9 away from each other, so that the connecting rod 1 8 and the connecting rod 2 9 can be rotated with the connecting disk 7 as the axis, so that the other ends of the connecting rod 1 8 and the connecting rod 2 9 can be close to each other, and then the clamping plate 11 can be driven to approach each other through the connecting block 10 and clamp the pulley to be processed. Subsequently, by starting the servo motor 2 5, the rotating shaft 3 connected to the output end can be driven to rotate. Under the joint action of the two rotating shafts 3, the transmission belt 4 arranged on the outer periphery can be driven to rotate. When the transmission belt 4 rotates and contacts with the pulley, the pulley to be processed can be driven to rotate by itself, thereby making the processing more convenient.

[0031] Reference Figure 1-Figure 3The clamping mechanism 2 includes an inner cavity 211, which is opened in the middle of the base 1. The inner bottom wall of the inner cavity 211 is fixedly connected to an electric push rod 210. The output end of the electric push rod 210 passes through the top wall of the base 1 and is fixedly connected to the connecting plate 7. A chamber 201 is opened on one side of the inner part of the base 1. A servo motor 202 is fixedly connected to one side of the bottom wall of the base 1. The output end of the servo motor 202 passes through the inner bottom wall of the chamber 201 and is fixedly connected to a threaded rod 207. The outer periphery of the threaded rod 207 is threadedly connected to a moving rod 206. The top end of the moving rod 206 passes through the top wall of the base 1 and is fixedly connected A support block 205 is connected, and the front and rear sides of the support block 205 are both rotatably connected to the connecting strip 204, and the two connecting strips 204 are both rotatably connected to the fixed block 203 at one end away from the support block 205, and the two fixed blocks 203 are respectively fixedly connected to the connecting rod 1 8 and the connecting rod 2 9; both sides of the threaded rod 207 are provided with limiting rods 208, and the bottom ends of the two limiting rods 208 are fixedly connected to the bottom wall of the chamber 201, and the top ends of the two limiting rods 208 are penetrated into the moving rod 206; the lower periphery of the moving rod 206 is fixedly connected to the limiting plate 209, and the limiting plate 209 is slidably connected to the inner wall of the chamber 201;

[0032] Specifically, by starting the electric push rod 210, the connection disk 7 and the clamping plate 11 connected to the output end can be driven to move up and down, so that the pulleys of different specifications clamped can contact the transmission belt 4. By starting the servo motor 202, the threaded rod 207 connected to the output end can be driven to rotate, and the threaded rod 207 can drive the connected moving rod 206 to move. Since the limiting rods 208 pass through both sides of the moving rod 206, the moving rod 206 can be limited by the limiting rods 208 to prevent the moving rod 206 from rotating with the rotation of the threaded rod 207. When the threaded rod 207 rotates, the movable rod 206 can be driven to move up and down. At the same time, the movable rod 206 can be positioned under the action of the limit plate 209, thereby preventing the movable rod 206 from detaching from the base 1. When the movable rod 206 moves, the two connecting strips 204 can be pushed to rotate in opposite directions through the support block 205, so that one end of the connecting rod 1 8 and the connecting rod 2 9 can be driven to open through the fixed block 203. When one end of the connecting rod 1 8 and the connecting rod 2 9 is opened, the other end will drive the clamping plate 11 to clamp the pulley, which can be used for the clamping effect of pulleys that do not meet the specifications.

[0033] Reference Figure 1-Figure 3 A support 13 is provided at the lower side of the base 1, and an electric push rod 14 is fixedly connected to the inner bottom wall of the support 13, and the output end of the electric push rod 14 passes through the top wall of the support 13 and is fixedly connected to the bottom wall of the base 1; the bottom end of the support 13 is rotatably connected to the chassis 12; the outer periphery of the bottom end of the support 13 is fixedly connected to a limiting ring 6, and the limiting ring 6 is rotatably connected to the inner wall of the chassis 12;

[0034] Specifically, by starting the electric push rod 14, the support plate 16 connected to the output end can be driven to move up and down, so that the height of the entire device can be adjusted. Rotating the pillar 13 can adjust the angle of the entire device, and under the action of the limiting ring 6, the pillar 13 can also be limited to ensure the stability of the rotation of the pillar 13 and prevent it from detaching from the chassis 12.

[0035] Working principle: In actual use, the staff can pull the connecting rod 1 8 and the connecting rod 2 9 away from each other, so that the connecting block 10 can drive the clamping plate 11 to approach each other and clamp the pulley to be processed, and then start the servo motor 2 5 to drive the rotating shaft 3 connected to the output end to rotate, so that the transmission belt 4 set on the outer periphery can be driven to rotate, and when the transmission belt 4 contacts the pulley, it can drive the pulley to be processed to rotate by itself, so that the processing is more convenient; in addition, by starting the electric push rod 1 210, the connecting disk 7 and the clamping plate 11 connected to the output end can be driven to move up and down, and by starting the servo motor 1 202, the connected threaded rod 207 can be driven to rotate, and the connected moving rod 206 can be driven to move up and down through the threaded rod 207. When the moving rod 206 moves, the two connecting strips 204 can be pushed to rotate in opposite directions through the support block 205, so that the connecting rod 1 8 and the connecting rod 2 9 can be driven to open through the fixed block 203 and clamp the pulley through the clamping plate 11, which can be applied to the clamping effect of pulleys that do not meet the specifications.
