Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, and more specifically, to a polishing device for machining mechanical parts. Background Technique

[0002] A polishing device for machining mechanical parts is a device used to improve the surface accuracy and quality of mechanical parts. In the field of mechanical processing, as an important component for supporting the belt on a conveyor, the surface finish of the conveying roller has relatively high requirements compared with traditional rollers. Therefore, the polishing of the conveying roller is a very important post-processing process, which can effectively improve the surface roughness and appearance quality of the parts, and even enhance the service performance of the parts.

[0003] In the prior art, the polishing wheel on the polishing device has a single structural design, mostly in the shape of a disc. When polishing a special conveying roller with a ring-shaped depression in the middle, since the special conveying roller is a round roller with frustum-shaped rollers at both ends, chamfering is often performed at the joint of the frustum-shaped roller and the round roller during the grinding stage. After entering the polishing stage, due to the problem of grinding accuracy, burrs of varying degrees are likely to appear on the chamfers generated by grinding. The traditional polishing wheel cannot synchronously grind the special conveying roller and its chamfers, and it is necessary to equip a polishing device with different polishing wheels, or manually polish with a hand-held angle grinder, resulting in an increase in the polishing operation cost of mechanical parts and low polishing efficiency. In view of this, we propose a polishing device for machining mechanical parts. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a polishing device for machining mechanical parts to solve the technical problems that the current traditional polishing wheel cannot synchronously grind the special conveying roller and its chamfers, and it is necessary to equip a polishing device with different polishing wheels, or manually polish with a hand-held angle grinder, resulting in an increase in the polishing operation cost of mechanical parts and low polishing efficiency.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A polishing device for machining mechanical parts, including a frame body composed of a rotary drive seat, a fixed frame, a telescopic mechanism, and a movable mounting plate.

[0006] The polishing mechanism includes a drive motor, a transfer rod is fixedly arranged at the output end of the drive motor, a connecting pipe is fixedly arranged at the lower end of the transfer rod, a polishing member is installed at the lower end of the connecting pipe, the polishing member includes a flat polishing part, an inclined surface polishing part is integrally formed on the flat polishing part, and a chamfer polishing part that fits the chamfer of the special conveying roller is constructed between the flat polishing part and the inclined surface polishing part.

[0007] The polishing piece structure composed of the flat polishing part, the inclined surface polishing part and the chamfer polishing part of the present utility model can improve the degree of fitting with the outer wall of the special conveying roller, reduce the existence of the fitting gap, and can perform polishing work when the driving motor rotates in the opposite direction to the rotary driving seat. The polishing effect can be improved through the surface contact of mutual fitting, reduce the probability of the chamfer on the special conveying roller not being polished, and reduce the steps of using other polishing devices or manual polishing. In this way, the cost of polishing the special conveying roller can be reduced and the polishing speed can be increased.

[0020] As Figures 1 to 4 shown, a polishing device for machining mechanical parts related to the present utility model includes a frame main body composed of a rotary drive seat 1, a fixed frame 2, a telescopic mechanism 3, and a movable mounting plate 4. A limit seat 7 is fixedly arranged at the top of the rotary end of the rotary drive seat 1, and a polishing mechanism 5 is movably arranged at the top of the movable mounting plate 4; the movable mounting plate 4 can control the up and down movement of the polishing mechanism 5 under the cooperation of the fixed frame 2 and the telescopic mechanism 3, facilitating the adjustment of the distance from the part. The part can be fixed in position and rotated under the cooperation of the rotary drive seat 1 and the limit seat 7, and the reverse rotation of the polishing mechanism 5 can improve the polishing effect on the part, increase the polishing range, and enhance the usage effect of the overall structure.

[0021] The polishing mechanism 5 includes a drive motor 501. An adapter rod 502 is fixedly arranged at the output end of the drive motor 501. A connecting pipe 503 is fixedly arranged at the lower end of the adapter rod 502. A polishing part 6 is installed at the lower end of the connecting pipe 503. The polishing part 6 includes a flat polishing part 601. An inclined surface polishing part 602 is integrally formed on the flat polishing part 601. A chamfer polishing part 603 that fits the chamfer of the special conveying roller is constructed between the flat polishing part 601 and the inclined surface polishing part 602; the position of the polishing part 6 can be fixed through the combination of the adapter rod 502 and the connecting pipe 503. The design of the flat polishing part 601 and the inclined surface polishing part 602 can strengthen the fit with the surface of the special conveying roller. At the same time, the chamfer polishing part 603 formed between the two can strengthen the fit with the chamfer at the connection of the special conveying roller, so that the polishing range can be increased and the existence of gaps can be reduced during the rotary polishing process.

[0022] In an embodiment of the utility model, a gap polishing portion 604 is integrally formed on the top of the plane polishing portion 601, and the top surface of the gap polishing portion 604 is higher than the center point of the special conveying roller; through the design of the gap polishing portion 604, the overall length of the polishing piece 6 can be made greater than half the height of the special conveying roller, so that when the grinding end of the special conveying roller is rotated and adjusted, the polishing gap in the middle can be avoided, thereby improving the integrity of the polishing.

[0023] In the embodiment of the utility model, a connecting hole 504 connected to the transfer rod 502 is opened on the top of the connecting tube 503, and threaded holes are opened on the side walls where the transfer rod 502 and the connecting hole 504 are connected, and screws 9 are connected between the interconnected threaded holes; such a combination facilitates disassembly and assembly operations.

[0024] In an embodiment of the utility model, a locking strip 505 is fixedly provided on the rod wall of the transfer rod 502, and a locking groove 506 combined with the locking strip 505 is opened on the groove wall of the connecting hole 504; the combination of the locking strip 505 and the locking groove 506 can further strengthen the connection strength between the transfer rod 502 and the connecting tube 503, and the stability of the position of the polishing part 6 can be improved during the rotational polishing process.

[0025] In the embodiment of the utility model, an electric push rod 8 corresponding to the position of the limit seat 7 is fixed on the top of the movable mounting plate 4, and the telescopic end of the electric push rod 8 is rotatably connected to the limit rod 801, and the special conveying roller is clamped and fixed in position by the cooperation of the limit seat 7 and the electric push rod 8; the limit rod 801 structure at the bottom of the electric push rod 8 cooperates with the limit seat 7 to facilitate the clamping and limiting of the special conveying roller, so that the rotation of the special conveying roller can be controlled by the action of the rotating drive seat 1 during the polishing process, which facilitates the polishing process.

[0026] Working principle: This embodiment provides a polishing device for machining mechanical parts. When in use, first insert one end of the special conveying roller into the top of the limit seat 7, and then start the electric push rod 8 to control the lower movement of the limit rod 801 to contact the top of the special conveying roller, achieving the effect of clamping and limiting, so that the polishing part 6 is in close contact with the special conveying roller. Then, the rotation of the polishing part 6 can be controlled by starting the driving motor 501. At the same time, the rotation driving seat 1 can be started to control the special conveying roller to move in the opposite direction, so as to carry out grinding treatment. The chamfer polishing part 603 designed between the plane polishing part 601 and the inclined plane polishing part 602 can effectively polish the chamfer of the special conveying roller, reduce the existence of polishing gaps, and effectively improve the polishing effect of the chamfer of the special conveying roller. After one end is polished, the special conveying roller can be rotated to adjust the polishing end, so that the other end can be polished. The design of the top gap polishing part 604 of the plane polishing part 601 can expand the grinding range of the middle part of the special conveying roller, reduce the probability of polishing gaps in the middle part, and further improve the integrity of polishing the special conveying roller. Through such a structural cooperation, the overall polishing operation can be completed at one time, improving the polishing speed.
