[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figure 1-3 As shown, this utility model provides a multi-station synchronous grinding and polishing assembly for a collaborative robot, including a support frame 1. Movable grinding mechanisms 3 are provided on both sides of the support frame 1. Two workpiece positioning mechanisms 2 are fixedly provided on one side of the support frame 1. Each workpiece positioning mechanism 2 includes a positioning frame 20. Two symmetrically distributed positioning blocks 22 are slidably arranged on the upper surface of the positioning frame 20. Positioning inclined plates 25 are provided on the upper surface of the positioning blocks 22. Fastening bolts 24 are slidably inserted into the upper surface of the positioning inclined plates 25, and the fastening bolts 24 are threaded onto the positioning blocks 22. In conjunction with the positioning inclined plate 25, a limiting inclined plate 28 is slidably provided on one side. A limiting bolt 26 is slidably inserted into the upper surface of the limiting inclined plate 28, and the limiting bolt 26 is threadedly engaged with the positioning inclined plate 25. A limiting groove 27 is formed on the upper surface of the limiting inclined plate 28, and the inner side of the limiting groove 27 is slidably fitted with the limiting bolt 26. When using the workpiece positioning mechanism 2, firstly, according to the size of the workpiece, the two positioning blocks 22 are slidably adjusted to a suitable position in the positioning groove 21 on the upper surface of the positioning frame 20 to ensure that they can symmetrically and stably support the workpiece. Then, the workpiece is placed on one side of the positioning block 22, and the fastening bolt 24 on the positioning inclined plate 25 is adjusted to be threadedly engaged with the positioning block 22, thereby fixing the position of the positioning inclined plate 25. Next, the limiting inclined plate 28 is slid until it is in close contact with the workpiece, and the threaded engagement of the limiting bolt 26 with the positioning inclined plate 25 and the sliding engagement of the limiting groove 27 with the limiting bolt 26 further stabilizes the workpiece and prevents it from shifting during the grinding and polishing process. The anti-slip pad 29 on one side of the limiting inclined plate 28 can enhance the stability of clamping and ensure the accurate positioning and stable clamping of the workpiece during the grinding and polishing process.
[0018] The mobile grinding mechanism 3 includes two motors 30, which are fixedly connected to both sides of the support frame 1. A movable screw 32 is fixedly mounted on the output end of each motor 30. Rotating frames 34 are fixedly mounted on both sides of the support frame 1. The inner side of each rotating frame 34 is rotatably connected to one end of a movable screw 32. A movable frame 37 is fitted onto the outer sides of both movable screws 32. A mounting groove 35 is provided on one side of each movable frame 37, and a grinding device 36 is mounted inside the mounting groove 35. When using the mobile grinding mechanism 3, the grinding device 36 is first installed in the mounting groove 35 on one side of the movable frame 37. Then, the motors 30 on both sides of the support frame 1 are started, and their output ends drive the movable screws 32 to rotate within the rotating frames 34. Since the movable frame 37 is fitted onto the outer sides of both movable screws 32, and one end of it slides against the sliding grooves 33 on both sides of the support frame 1, the rotation of the movable screws 32 drives the movable frame 37 to move along the sliding grooves 33. As the moving frame 37 moves, the grinding equipment 36 will perform grinding and polishing operations on the workpiece fixed on the workpiece positioning mechanism 2, realizing synchronous grinding and polishing of multiple stations.
[0019] Multiple positioning grooves 21 are formed on the upper surface of the positioning frame 20. Through the sliding engagement of the multiple positioning grooves 21 with the positioning block 22, the position of the positioning block 22 can be flexibly adjusted to adapt to workpieces of different sizes and shapes, improving the versatility and adaptability of the equipment. Positioning holes 23 are formed on the upper surface of the positioning block 22. The positioning holes 23 engage with the threaded fastening bolts 24, allowing the positioning inclined plate 25 to be firmly fixed on the positioning block 22, thereby ensuring the stability of the workpiece during initial positioning and preventing it from shifting during subsequent operations. An anti-slip pad 29 is fixed to one side of the limiting inclined plate 28. The anti-slip pad 29 increases the friction between the limiting inclined plate 28 and the workpiece, further stabilizing the position of the workpiece and preventing it from sliding or shifting due to vibration or external force during grinding and polishing, thus improving the quality and precision of grinding and polishing.
[0020] Mounting brackets 31 fixed on both sides of the support frame 1 provide stable support for the motor 30, ensuring the stability and reliability of the motor 30 during operation, thereby guaranteeing the normal operation and efficient work of the mobile grinding mechanism 3. Sliding grooves 33 on both sides of the support frame 1 slide against one end of the moving frame 37, providing a stable moving track for the moving frame 37, ensuring its smoothness and accuracy during movement, thereby ensuring that the grinding equipment 36 performs uniform and consistent grinding and polishing operations on the workpiece.
[0021] Working Principle: When using the workpiece positioning mechanism 2, firstly, according to the size of the workpiece, the two positioning blocks 22 are slidably adjusted to a suitable position within the positioning grooves 21 on the upper surface of the positioning frame 20 to ensure they can symmetrically and stably support the workpiece. Then, the workpiece is placed on one side of the positioning block 22, and the fastening bolts 24 on the positioning inclined plate 25 are adjusted to engage with the threaded parts of the positioning block 22, thereby fixing the position of the positioning inclined plate 25. Next, the sliding limiting inclined plate 28 is slid until it is in close contact with the workpiece, and the threaded engagement of the limiting bolts 26 with the positioning inclined plate 25, and the sliding contact between the limiting groove 27 and the limiting bolts 26, further stabilize the workpiece and prevent it from shifting during grinding and polishing. The anti-slip pad 29 on one side of the limiting inclined plate 28 enhances the stability of the clamping, ensuring accurate positioning and stable clamping of the workpiece during grinding and polishing.
[0022] When using the mobile grinding mechanism 3, the grinding equipment 36 is first installed in the mounting groove 35 on one side of the mobile frame 37. Then, the motors 30 on both sides of the support frame 1 are started, and the output ends of the motors 30 drive the moving screws 32 to rotate within the rotating frame 34. Since the mobile frame 37 is sleeved on the outside of the two moving screws 32, and one end of it slides against the sliding grooves 33 on both sides of the support frame 1, the rotation of the moving screws 32 will drive the mobile frame 37 to move along the sliding grooves 33. As the mobile frame 37 moves, the grinding equipment 36 will perform grinding and polishing operations on the workpiece fixed on the workpiece positioning mechanism 2, realizing synchronous grinding and polishing at multiple stations.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
