Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a polishing machine head. Background Technology

[0002] Polishing machines, also known as grinding machines, are mainly used for fully automatic surface polishing of workpieces. They are suitable for small workpieces and for automatically polishing metal workpieces to improve surface gloss and remove burrs. These machines are relatively simple to operate, require low operator skills, and can improve production efficiency, reduce labor intensity, save production costs, improve product quality, and reduce product quality differences. The polishing head is the key component of the polishing operation. Traditional polishing machines usually only include one polishing wheel. Because the polishing head and polishing wheel are usually connected by a flange or bolts, and the machine head and polishing wheel are integrated, the polishing wheel angle is fixed, making it impossible to perform targeted polishing and grinding as needed. This results in inflexible polishing and reduced effectiveness. Utility Model Content

[0007] The fixing component includes a fixing recess that is fixedly connected to the side wall of the assembly recess. The inner walls of the fixing recess are rotatably connected to the two sides of the fixing shaft, and the outer walls of the fixing shaft are fixedly sleeved with a fixing spiral plate.

[0008] As a further description of the above technical solution:

[0009] The fixed spiral plate is movably engaged with the assembly rotating block. Two fixing grooves are provided on the side wall of the fixed spiral plate. A fixed slider is slidably connected inside the fixing groove. The bottom of the fixed slider is fixedly connected to the inner wall of the fixing groove by a fixing spring.

[0010] As a further description of the above technical solution:

[0011] A fixed pull plate is fixedly connected between the two fixed sliders, and a fixed insert is fixedly connected to the bottom of the fixed pull plate. The fixed insert is movably inserted into one of the assembly holes.

[0018] This utility model has the following beneficial effects:

[0019] The fixing components—fixed recess, fixed shaft, fixed retaining plate, fixed slider, fixed spring, fixed pull plate, and fixed insert—cooperate to rotate the polishing head and polishing disc on the mounting block via the mounting block. This allows the polishing disc to be adjusted vertically to a suitable angle. Next, the fixed retaining plate is pried open and flipped, causing it to engage with the mounting block. Then, the fixed pull plate is released, allowing the fixed spring to provide a restoring force to the fixed insert, which then engages with a mounting hole on the mounting block. The driving components—the driving L-shaped block, driving insert, driving pull block, and driving spring—cooperate to rotate the polishing head along the mounting block surface to a suitable angle via the driving shaft. Then, the driving pull block is released, allowing the driving spring to provide a restoring force to the driving insert, which then engages with a driving hole on the driving shaft. This allows for targeted polishing of the polishing wheel on the head, improving performance. Attached Figure Description

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.

[0027] Reference Figure 1-4This utility model provides a polishing machine head, including a polishing machine body 1. An assembly handle 2 is fixedly connected between the two sides of the outer wall of the polishing machine body 1. An assembly recess 3 is fixedly connected to the surface of the polishing machine body 1. An assembly shaft 4 is rotatably connected between the two sides of the inner wall of the assembly recess 3. An assembly block 5 is fixedly sleeved on the outer wall of the assembly shaft 4. One end of the assembly shaft 4 passes through the assembly recess 3 and is fixedly connected to an assembly block 7. Multiple assembly insertion holes are provided on the side wall of the assembly block 7. A fixing component is connected to the side wall of the assembly recess 3, which serves to limit the adjustment of the assembly block 5. The fixing component includes a fixing recess fixedly connected to the side wall of the assembly recess 3. 8. Fixed rotating shafts 9 are rotatably connected to both sides of the inner wall of the fixed recess 8. Fixed rotating shafts 9 are fixedly sleeved on the outer wall of the fixed rotating shafts 9. The fixed rotating shafts 9 are movably engaged with the assembly rotating block 7. The side wall of the fixed rotating shafts 10 has two fixed grooves. Fixed sliders 11 are slidably connected inside the fixed grooves. The bottom of the fixed sliders 11 is fixedly connected to the inner wall of the fixed grooves through a fixed spring 12. Fixed pull plates 13 are fixedly connected between the two fixed sliders 11. Fixed inserts 14 are fixedly connected to the bottom of the fixed pull plates 13. Fixed inserts 14 are movably inserted into one of the assembly holes. The movable insertion of fixed inserts 14 into one of the assembly holes serves as a limiting action.

[0028] A polishing head 15 is rotatably connected to the surface of the assembly block 5 via a drive shaft 6. A polishing disc 16 is fixedly connected to the output end of the polishing head 15. Multiple drive insertion holes are provided on the outer side wall of the drive shaft 6. A drive assembly is connected to the back of the polishing head 15. The drive assembly includes a drive L-shaped block 17 fixedly connected to the back of the polishing head 15. A drive insert 18 is provided through the top of the drive L-shaped block 17. A drive pull block 19 is fixedly connected to one end of the drive insert 18. The other end of the drive insert 18 is movably inserted into one of the drive insertion holes. A drive spring 20 is movably sleeved on the outer side wall of the drive insert 18. The two ends of the drive spring 20 are fixedly connected to the side wall of the drive pull block 19 and the side wall of the drive L-shaped block 17, respectively. The movable insertion of the drive insert 18 into one of the drive insertion holes serves as a limiting action.

[0029] Working principle: In use, first rotate the assembly rotating block 7, which drives the assembly matching block 5 on the assembly rotating shaft 4 to rotate. Then, the assembly matching block 5 also drives the polishing head 15 and polishing disc 16 on the drive rotating shaft 6 to rotate, so that the polishing disc 16 can be adjusted up and down to a suitable angle. Then, pull the fixed pull plate 13, so that the fixed pull plate 13 drives the fixed slider 11 and the fixed spring 12 to slide inside the fixed groove. Then, bend and flip the fixed return plate 10, so that the inside of the fixed return plate 10 is movably engaged with the assembly rotating block 7. Then, release the fixed pull plate 13, so that the fixed spring 12 resets the fixed pull plate 13 and the fixed insert 14 on the fixed slider 11, so that the fixed insert 14 is movably engaged with an assembly insertion hole on the assembly rotating block 7 to ensure the adjustment and limiting effect.

[0030] Pulling the drive block 19 causes the drive insert 18 and drive spring 20 to move along the direction of the drive L-shaped block 17. Then, the drive insert 18 separates from one of the drive sockets. Then, the polishing head 15 is rotated so that the polishing head 15 rotates to a suitable angle along the surface of the mounting block 5 via the drive shaft 6. Then, the drive block 19 is released so that the drive spring 20 gives the drive insert 18 a restoring force, so that the drive insert 18 is inserted into and limited by one of the drive sockets on the drive shaft 6, ensuring further adjustment and limiting effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
