[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Example 1: This example provides a feeding device for a polishing machine 2, such as... Figure 1 As shown, the polishing machine 2 includes a feeding assembly 1 and a driving component 3. The feeding assembly 1 includes a guide rail 11 and a clamping component 12. The guide rail 11 is used to be disposed on the feeding side of the polishing machine 2. The clamping component 12 is used to clamp the workpiece to be processed, and the clamping component 12 is slidably disposed on the guide rail 11. The driving component 3 is connected to the clamping component 12. The driving component 3 is used to drive the clamping component 12 to move closer to or away from the polishing machine 2 along the guide rail 11.

[0026] For example, in implementation, guide rail 11 is used to be mounted on the feed side of polishing machine 2.

[0027] The clamping member 12 can be a pneumatic gripper, hydraulic clamp, electromagnetic chuck, or other type of clamping device. The clamping member 12 is used to clamp the workpiece to be processed (such as pipe fittings, shaft parts, etc.), and it is slidably mounted on the guide rail 11. This allows the clamping member 12 to slide along one end of the guide rail 11 to the other end.

[0028] The driving component 3 can be a linear driving mechanism such as a cylinder, hydraulic telescopic rod, or other telescopic mechanism. The driving component 3 is connected to the guide rail 11 by means of screwing, welding, or other methods, and its output shaft is connected to the clamping component 12. This allows the driving component 3 to drive the clamping component 12 to reciprocate along one end of the guide rail 11 towards the other end when it operates.

[0029] During operation, the guide rail 11 is installed on the feed side of the polishing machine 2, extending from the discharge side of the polishing machine 2 towards the feed side. When polishing is required, the drive unit 3 is first operated to move the clamping member 12 along the guide rail 11 to the end of the guide rail 11 away from the polishing machine 2. Next, the clamping member 12 clamps one end of the workpiece, extending it towards the polishing machine 2. Then, the drive unit 3 is operated to move the clamping member 12 along the guide rail 11 towards the polishing machine 2. At this time, the workpiece is gradually pushed into the polishing area of ​​the polishing machine 2 for polishing. Firstly, by automatically pushing the clamping member 12 along the guide rail 11 via the drive unit 3, continuous or intermittent automatic feeding of the workpiece is achieved, aiming to reduce manual operation and improve production efficiency. Secondly, after the workpiece is clamped by the clamping member 12, it enters the polishing machine 2 along a fixed path, aiming to reduce potential positional deviations that may occur during manual feeding, thereby ensuring consistent processing quality. Thirdly, automated feeding reduces the risk of operators directly contacting the polishing equipment, aiming to improve operational safety. Fourthly, the driving member 3 can drive the clamping member 12 to different positions on the guide rail 11 to clamp the workpiece, aiming to adapt to workpieces of different lengths and thus increase the applicability of the feeding device.

[0030] Example 2: Based on Example 1 above, in this example, as follows... Figure 2 As shown, the clamping member 12 includes a slider 121 and a clamping plate 122; the slider 121 is slidably disposed on the guide rail 11 and is connected to the driving member 3; there are two clamping plates 122, which are disposed opposite to each other on both sides of the slider 121; the clamping plate 122 includes a connecting unit 1221, a clamping unit 1222, and a driving rod 1223; the connecting unit 1221 is disposed on the slider 121; the driving rod 1223 passes through the connecting unit 1221 and is screwed to the connecting unit 1221; the clamping unit 1222 is rotatably connected to the driving rod 1223 and is located between the two connecting units 1221.

[0031] For example, in implementation, the clamping member 12 includes a slider 121 and a clamping plate 122. The slider 121 is slidably mounted on the guide rail 11. For instance, a groove is formed on the lower surface of the slider 121, and the guide rail 11 is fitted into the groove to achieve the purpose of slidably connecting the slider 121 to the guide rail 11. The driving member 3 is connected to the slider 121 to drive the slider 121 to reciprocate along the guide rail 11 when the driving member 3 is operated.

[0032] The clamping plate 122 is used to clamp the workpiece to be processed (such as pipe fittings, shaft parts, etc.), and the clamping plate 122 is connected to the slider 121 by welding, screwing or other means. There are two clamping plates 122, which are symmetrically distributed on both sides of the slider 121.

[0033] The clamping plate 122 includes a connecting unit 1221, a clamping unit 1222, and a drive rod 1223.

[0034] The connecting unit 1221 is installed on one side of the upper plate of the slider 121 by means of welding, screwing, or integral molding.

[0035] The drive rod 1223 passes through the connecting unit 1221. The drive rod 1223 extends from one side of the slider 121 to the other side of the slider 121, and the drive rod 1223 is screwed to the connecting unit 1221.

[0036] The clamping unit 1222 is connected to one end of the drive rod 1223 through shaft hole connection, bearing connection or other means, and the clamping unit 1222 is located between the two connecting units 1221.

[0037] During operation, the drive unit 3 is first operated to move the slider 121 along the guide rail 11 to the end of the guide rail 11 away from the polishing machine 2, thereby moving the clamping plate 122 to the end of the guide rail 11 away from the polishing machine 2. Next, the two drive rods 1223 are rotated to move the two clamping units 1222 away from each other. Then, the workpiece to be processed is placed between the two clamping units 1222, extending along the clamping units 1222 towards the polishing machine 2, and the two drive rods 1223 are rotated in the opposite direction to bring the two clamping units 1222 closer together, thus clamping the workpiece between them. By operating the drive rods 1223, the position of the clamping units 1222 can be adjusted to ensure that the workpiece to be processed can be accurately transported into the polishing area of ​​the polishing machine 2. Next, the drive unit 3 is activated to move the slider 121 along the guide rail 11 towards the polishing machine 2, thereby driving the clamping unit 1222 to move synchronously along the guide rail 11 towards the polishing machine 2. At this time, the workpiece to be processed is gradually pushed into the polishing area of ​​the polishing machine 2 for polishing. The clamping unit 12 is divided into a modular structure of slider 121 and clamping plate 122, which makes the functional division of each component clear, in order to facilitate standardized production, assembly and subsequent replacement and maintenance.

[0038] By varying the screw distances of the two drive rods 1223, the position of the workpiece to be processed in the width direction of the guide rail 11 can be different. This is intended to facilitate the alignment of the workpiece with the processing area of ​​the polishing machine 2.

[0039] In one optional embodiment, the driving component 3 is a drive motor, and the driving component 3 is mounted on the slider 121. A rack extending along the guide rail 11 is provided, and a gear is provided on the output shaft of the driving component 3, with the gear meshing with the rack. When the driving component 3 operates, the gear moves along the rack, thereby driving the slider 121 and the driving component 3 to move synchronously.

[0040] Example 3: Based on Example 2 above, in this example, as follows... Figure 2 As shown, the clamping unit 1222 has an arc-shaped structure that bends toward the connecting unit 1221 on the side away from the connecting unit 1221.

[0041] For example, in implementation, the side of the clamping unit 1222 away from the connecting unit 1221 is formed into an arc-shaped structure that bends toward the connecting unit 1221. This is intended to facilitate clamping of workpieces with cylindrical or near-cylindrical surfaces (such as pipes, shaft parts, etc.).

[0042] Example 4: Based on Example 3 above, in this example, as... Figure 2As shown, the feeding assembly 1 also includes a limiting plate 13; the limiting plate 13 is disposed at the end of the slider 121 away from the polishing machine 2.

[0043] For example, in implementation, the feeding device also includes a limiting plate 13. The limiting plate 13 is installed on the end of the slider 121 away from the polishing machine 2 by welding, screwing, or integral molding. During the process of the driving member 3 driving the slider 121 to move the workpiece towards the polishing machine 2, the limiting plate 13 can abut against the end of the workpiece away from the polishing machine 2. This aims to reduce the risk of the workpiece sliding out of the clamping unit 1222 along the guide rail 11 in the direction away from the polishing machine 2, thereby ensuring that the workpiece can be accurately conveyed into the polishing area of ​​the polishing machine 2.

[0044] Example 5: Based on Example 1 above, in this example, as follows... Figure 2 As shown, the feeding assembly 1 also includes a support member 14; the support member 14 includes a bracket 141 and a roller 142; the bracket 141 is disposed at one end of the guide rail 11 near the polishing machine 2; the roller 142 is rotatably disposed on the upper end of the bracket 141, and the roller 142 is used to fit against the lower surface of the workpiece to be processed.

[0045] For example, in implementation, the feeding assembly 1 further includes a support member 14. The support member 14 includes a bracket 141 and a roller 142.

[0046] The bracket 141 is connected to the end of the guide rail 11 near the polishing machine 2 by means of welding, screwing, or integral molding.

[0047] The roller 142 is rotatably connected to the upper end of the bracket 141 through bearing connection, shaft hole connection, etc., and the roller 142 extends along one side of the guide rail 11 to the other side.

[0048] During operation, when polishing is required, the drive unit 3 is first operated to move the clamping member 12 along the guide rail 11 to the end of the guide rail 11 away from the polishing machine 2. Next, the clamping member 12 clamps one end of the workpiece, causing it to extend towards the polishing machine 2, and the lower surface of the other end of the workpiece is placed against the upper surface of the roller 142. This aims to support the other end of the workpiece, thereby reducing the risk of tilting. Then, the drive unit 3 is operated to move the clamping member 12 along the guide rail 11 towards the polishing machine 2. At this time, the workpiece is gradually pushed into the polishing area of ​​the polishing machine 2 for polishing. The roller 142 begins to rotate under the friction between the roller 142 and the workpiece, providing rolling support for the workpiece. This aims to make it easier to push the workpiece into the polishing area of ​​the polishing machine 2, thereby improving overall feeding efficiency.

[0049] Example 6: Based on Examples 1 to 5 above, in this example, as follows... Figure 1 As shown, there are two feeding components 1, which are symmetrically distributed on the feed side and discharge side of the polishing machine 2.

[0050] For example, in implementation, two feeding components 1 are provided. These two feeding components 1 are symmetrically distributed on the inlet and outlet sides of the polishing machine 2. The feeding component 1 located on the inlet side of the polishing machine 2 is used to feed the workpiece to be processed into the polishing area of ​​the polishing machine 2. The feeding component 1 located on the outlet side of the polishing machine 2 is used to remove the polished workpiece from the polishing area of ​​the polishing machine 2.

[0051] During operation, when polishing is required on the workpiece, the drive unit 3 is first operated to move the clamping member 12 located on the feed side of the polishing machine 2 along the guide rail 11 to the end of the guide rail 11 away from the polishing machine 2. Next, the clamping member 12 on the feed side of the polishing machine 2 clamps one end of the workpiece, causing it to extend towards the polishing machine 2 along the clamping member 12. Then, the drive unit 3 is operated to move the clamping member 12 on the feed side of the polishing machine 2 towards the polishing machine 2 along the guide rail 11. At this time, the workpiece is gradually pushed into the polishing area of ​​the polishing machine 2 for polishing.

[0052] After polishing, the workpiece is output from the discharge side of the polishing machine 2. At this time, the clamping member 12 located on the discharge side of the polishing machine 2 clamps the other end of the workpiece and moves the workpiece away from the polishing machine 2 along the guide rail 11. By loading and unloading the workpiece from the feed side and discharge side of the polishing machine 2, it is hoped to ensure a smooth transition of the workpiece throughout the entire processing, thereby reducing the risk of operational errors caused by human intervention.

[0053] Example 7: Based on Example 1 above, in this example, as follows... Figure 3 As shown, the feeding device further includes a loading assembly 4; the loading assembly 4 includes a storage rack 41 and a loading component 42; the storage rack 41 is disposed on one side of the guide rail 11, and the storage rack 41 is used to store workpieces to be processed; the loading component 42 is disposed on the side of the storage rack 41 near the guide rail 11; the loading component 42 includes a picking plate 423, a first driving unit 421 and a second driving unit 422; the first driving unit 421 is disposed on the side of the storage rack 41 near the guide rail 11; the second driving unit 422... 422 is disposed on the first drive unit 421, and the second drive unit 422 is used to move closer to or further away from the clamping member 12 along the direction of the storage rack 41 toward the guide rail 11 under the drive of the first drive unit 421; the picking plate 423 is disposed on the upper end of the second drive unit 422, the picking plate 423 is used to pick up the workpiece to be processed from the storage rack 41, and the picking plate 423 is used to extend and retract along the direction of the lower end of the storage rack 41 toward the upper end of the storage rack 41 under the drive of the second drive unit 422.

[0054] For example, in the implementation process, the feeding device also includes a feeding assembly 4, which includes a storage rack 41 and a feeding component 42.

[0055] The storage rack 41 is installed on one side of the guide rail 11 by welding, screwing, or other methods. An appropriate distance is maintained between the storage rack 41 and the guide rail 11 to ensure that the storage rack 41 does not interfere with the normal movement of the clamping member 12 and the workpiece. The storage rack 41 is used to store workpieces to be processed.

[0056] The feeding component 42 is connected to the storage rack 41 near the guide rail 11 by welding, screwing, or other methods. The feeding component 42 includes a picking plate 423, a first drive unit 421, and a second drive unit 422. Both the first drive unit 421 and the second drive unit 422 can be linear drive mechanisms such as cylinders, hydraulic telescopic rods, or other telescopic mechanisms. The first drive unit 421 is connected to the storage rack 41 near the guide rail 11 by welding, screwing, or other methods. The second drive unit 422 is located on the side of the first drive unit 421 near the guide rail 11 and is connected to the output shaft of the first drive unit 421 by welding, screwing, or other methods. The picking plate 423 is located at the upper end of the second drive unit 422 and is connected to the output shaft of the second drive unit 422 by welding, screwing, or other methods.

[0057] During operation, the workpiece to be processed is first placed on the upper end of the storage rack 41, positioned above the loading component 42. Next, the first drive unit 421 drives the second drive unit 422 to move along the guide rail 11 towards the storage rack 41, thereby moving the picking plate 423 directly below the workpiece. Then, the second drive unit 422 drives the picking plate 423 to move from the lower end of the storage rack 41 towards the upper end, gradually bringing the upper surface of the picking plate 423 into contact with the lower surface of the workpiece until it separates from the storage rack 41. Further, the first drive unit 421 drives the second drive unit 422 to move along the storage rack 41 towards the guide rail 11 until the second drive unit 422 is positioned directly above the guide rail 11, causing the clamping component 12 to clamp one end of the workpiece. Finally, the second drive unit 422 drives the picking plate 423 to move from the upper end of the storage rack 41 to the lower end of the storage rack 41 until the picking plate 423 separates from the workpiece to be processed. Then, the first drive unit 421 drives the second drive unit 422 to move closer to the storage rack 41. This is intended to facilitate the loading of the workpiece to be processed onto the clamping member 12.

[0058] In one optional implementation, a plurality of the aforementioned feeding components 42 are arranged sequentially along the extension direction of the guide rail 11. This aims to provide support at multiple locations along the length of the workpiece to be processed, thereby reducing the risk of tilting and improving the stability of the workpiece during transport.

[0059] In one optional implementation, the upper surface of the take-up plate 423 is provided with a receiving groove for accommodating the workpiece to be processed. This aims to reduce the risk of the workpiece slipping off the take-up plate 423.

[0060] Example 8: Based on Example 1 above, in this example, as follows... Figure 1 As shown, the feeding device also includes a dust suction component 5; the dust suction component 5 is used to be installed on the polishing machine 2, and the dust suction component 5 is used to correspond to the polishing area of ​​the polishing machine 2.

[0061] For example, in implementation, the above-mentioned feeding device also includes a dust collection component 5. The dust collection component 5 can be an existing vacuum cleaner or dust collection device. This dust collection component 5 is connected to the polishing machine 2 by means of screw fixing, snap-fit, or other methods, and the feed inlet of the dust collection component 5 faces the polishing area of ​​the polishing machine 2. The aim is to adsorb and collect the debris generated during the polishing process of the polishing machine 2.
