Description

Technical Field

[0001] The utility model relates to the field of drag-type polishing machines, and more specifically to a multi-angle adjustment mechanism of a drag-type polishing machine. Background Art

[0002] A drag polisher is a mechanical device used for surface treatment. It mainly clamps the workpiece on a fixture and makes it rotate and drag at high speed in the abrasive. It uses the pressure and high-speed relative motion generated by the contact between the workpiece and the abrasive to remove burrs, scratches, oxide layers and other defects on the workpiece surface to achieve the purpose of improving the surface quality of the workpiece.

[0003] In the prior art, in the actual polishing work using a drag-type polisher, the shapes of the workpieces are varied. For workpieces with complex shapes, such as workpieces with multiple curved parts or surfaces with different inclination angles, the inability to adjust the angle of the chuck rod will cause certain parts of the workpiece to be unable to fully contact the abrasive. For example, when polishing a metal ornament with a concave arc, the chuck rod with a fixed angle may not allow the abrasive to reach the concave part, resulting in incomplete polishing, leaving unpolished areas on the workpiece surface. Therefore, we propose a multi-angle adjustment mechanism for a drag-type polisher to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multi-angle adjustment mechanism for a drag-type polishing machine, which adjusts the angle of the connecting head. The rotation of the connecting head will drive the rotation of the chuck rod and then drive the rotation of the arc slide rail. Since a plurality of positioning holes are provided on the surface of the arc slide rail, the chuck rod can be adjusted to a plurality of angles. After the chuck rod is adjusted to a suitable angle, a pin is used to fix the angle of the arc slide rail and then the chuck rod. At this time, when the workpiece to be polished is fixed on the chuck rod, it can be polished at a suitable angle, thereby improving the polishing effect of the workpiece.

[0022] Example 1: Please refer to Figure 1 - Figure 5 A multi-angle adjustment mechanism of a dragging polishing machine includes a connection plate 1 and a chuck rod 2. A plurality of fixing bolts 3 are installed on the surface of the connection plate 1. The end of the fixing bolt 3 away from the connection plate 1 is fixedly connected to a frame 4. The inner wall of the frame 4 is rotatably connected to a fixing plate 5. One side of the fixing plate 5 is fixedly connected to a connector 6. The chuck rod 2 is fixedly connected to the connector 6. The surface of the connector 6 is fixedly connected to two arc-shaped slide rails 7. The arc surface of the fixing bolt 3 is fixedly connected to a fixing ring 8. The arc surface of the fixing ring 8 is fixedly connected to two round rods 9. The round rods 9 are slidably connected to the inner wall of the arc-shaped slide rail 7. The arc surface of the fixing bolt 3 is fixedly connected to a ring 10. Two latches 11 are slidably penetrated on the surface of the ring 10. The surface of the arc-shaped slide rail 7 is provided with a plurality of positioning holes 12. The size of the latch 11 matches the size of the positioning hole 12. The arc surface of the latch 11 is sleeved with a spring 13. The two ends of the spring 13 are fixedly connected to the latch 11 and the ring 10, respectively. One end of the latch 11 is fixedly connected to a pull ring 14. The arc surface of the round rod 9 is sleeved with a sleeve 15, and the outer arc surface of the sleeve 15 slides with the arc slide rail 7. The surface of the connector 6 is fixedly connected to a telescopic sleeve 16, and the end of the telescopic sleeve 16 close to the connecting disk 1 is fixedly connected to an iron ring, and the surface of the connecting disk 1 is fixedly connected to a plurality of magnetic blocks 17. The surface of the connector 6 is fixedly connected to a plurality of baffles 18, and the baffles 18 are respectively located on both sides of the inner wall and the outer wall of the telescopic sleeve 16.

[0023] Working principle: When the angle of the chuck rod 2 needs to be adjusted during polishing of the drag polisher, first pull the telescopic sleeve 16, which will drive the iron ring to separate from the magnetic block 17. When the iron ring is separated from the magnetic block 17, the telescopic sleeve 16 will shrink. The shrinkage of the telescopic sleeve 16 will drive the iron ring to move away from the connecting plate 1. The telescopic sleeve 16 will slide along the surface of the baffle 18. The baffle 18 can limit the moving path of the telescopic sleeve 16, thereby preventing the telescopic sleeve 16 from twisting when shrinking. When shrinking, the telescopic sleeve 16 will cause the fixing bolt 3 to move. Gradually exposed, when the telescopic sleeve 16 is compressed to a suitable size, the two pull rings 14 are pulled at this time, the movement of the pull ring 14 will drive the bolt 11 to move, the movement of the bolt 11 will slide in the ring 10 and gradually come out of the positioning hole 12, the bolt 11 will stretch the spring 13 when moving, when the bolt 11 comes out of the positioning hole 12, the connector 6 is rotated, the connector 6 will drive the fixing plate 5 to rotate in the frame 4, the rotation of the connector 6 will drive the clamp rod 2 to rotate, and at the same time the connector 6 will drive the arc slide rail 7 to rotate, the arc The slide rail 7 will slide along the surface of the sleeve on the round rod 9 when it rotates. The sleeve will rotate on the arc surface of the round rod 9 with the help of the force of the arc slide rail 7. The round rod 9 can limit the rotation path of the arc slide rail 7. The sleeve can reduce the friction between the round rod 9 and the arc slide rail 7 when sliding, thereby facilitating the rotation of the connecting head 6. When the clamp rod 2 is rotated to a suitable angle, the pull ring 14 is released, and the pin 11 is inserted into the positioning hole 12 with the help of the contraction force of the spring 13. Because a plurality of positioning holes 12 are provided on the surface of the arc slide rail 7, the clamp rod 2 can be 2 is adjusted to multiple angles, the latch 11 limits the rotation of the arc-shaped slide rail 7, and then limits the chuck rod 2 after it rotates to a suitable angle. At this time, the chuck rod 2 is adjusted to a suitable angle, and then the telescopic sleeve 16 is pulled in the direction close to the connecting plate 1. The movement of the telescopic sleeve 16 drives the iron ring to move in the direction close to the magnetic block 17 until the iron ring is adsorbed on the surface of the magnetic block 17. The telescopic sleeve 16 is convenient for covering the fixing bolt 3, thereby preventing the polishing sand from entering the gap between the parts on the fixing bolt 3 when polishing the workpiece.

[0024] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
