Description

Technical Field

[0001] This invention relates to the field of parts processing technology, specifically a polishing device for processing mechanical parts. Background Technology

[0002] After machining, mechanical parts typically require surface polishing to remove burrs, improve smoothness, enhance appearance, or prepare for subsequent processing (such as electroplating or spraying). Uniform polishing of the outer surface is particularly crucial for parts with rotating characteristics, such as sleeves and tubing.

[0003] Currently, polishing of such parts mainly relies on manual polishing by operators using handheld angle grinders and polishing wheels. This method is not only labor-intensive and inefficient, but the polishing quality also largely depends on the worker's experience and skill, making it difficult to guarantee the consistency and uniformity of polishing across the entire workpiece surface. This is especially true for long workpieces, which are more prone to localized over-polishing or under-polishing. Furthermore, manual polishing generates a large amount of dust, posing a threat to the health of operators and polluting the workshop environment. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a polishing device for machining mechanical parts that has good polishing effect, can improve work efficiency, effectively reduce polishing dust, and improve the working environment.

[0014] 2. This device significantly reduces the labor intensity of operators and improves production efficiency. The workpiece is securely clamped by the parts clamping mechanism, and the polishing process is automatically completed by the drive assembly, replacing the traditional manual operation mode using hand tools. This makes polishing operations more labor-saving and efficient, and is conducive to continuous processing.

[0015] 3. The integrated dust collection system effectively collects dust generated during the polishing process. The dust hood is positioned close to the polishing point, and the dust is drawn into the dust collection box by a vacuum cleaner, significantly improving the working environment, reducing health hazards to operators, and meeting the environmental protection requirements of clean production.

[0016] 4. The device has good adaptability and versatility.

[0017] 5. The entire device has a coordinated structure and stable operation. The drive assembly simultaneously drives the workpiece rotation, polishing head rotation, and polishing unit feed via sprockets and chains, realizing the linkage of multiple actions, ensuring the smoothness and reliability of the polishing process, and contributing to obtaining stable processing results.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-8 The present invention provides a polishing device for machining mechanical parts, including a machining table 1, a part clamping mechanism 2, and a progressive polishing device 3. The machining table 1 is the basic platform of the entire device, which is usually made of metal sheet by welding or casting, and has sufficient rigidity and stability. The part clamping mechanism 2 is fixedly connected to one side of the upper end of the machining table 1 for fixing the part to be polished. The progressive polishing device 3 is fixedly connected to the machining table 1 on one side of the part clamping mechanism 2 for realizing progressive polishing operation on the clamped part.

[0022] Please see Figure 2 and Figure 3Specifically, the progressive polishing device 3 includes a side plate 101, a translation plate 102, a sliding sleeve 103, a spline sleeve 104, a polishing shaft 105, a polishing head 106, and a first cylinder 107. Two sets of symmetrical side plates 101 are fixedly connected to the processing table 1. To improve the structural strength and stability of the side plates 101, a bent plate 204 is usually fixedly connected between the side plates 101 and the processing table 1. Several reinforcing ribs 205 are fixedly connected between the bent plates 204. The side plates 101 are connected by sliding members. The sliding plate 102 is dynamically connected. In this embodiment, the specific structure of the sliding member includes: at least two sets of sliding rails 201 are fixedly connected to the front and rear sides of the sliding plate 102, and sliding blocks 202 are fixedly connected to the opposite side of the side plate 101. A plurality of sliding grooves 203 matching the sliding rails 201 are opened on the opposite side of the sliding blocks 202, and the sliding rails 201 are slidably connected in the corresponding sliding grooves 203, thereby realizing the smooth linear movement of the sliding plate 102 relative to the side plate 101.

[0023] Please see Figure 3 The upper and lower edges of the translation plate 102 are respectively fixedly connected to the sliding sleeve 103. The sliding sleeve 103 is rotatably connected to the spline sleeve 104 through the bearing (such as the deep groove ball bearing). The spline shaft 108 is slidably connected inside the spline sleeve 104. That is, the outer spline of the spline shaft 108 meshes with the inner spline of the spline sleeve 104, so that the spline shaft 108 can both drive the spline sleeve 104 to rotate and slide axially inside the spline sleeve 104. One end of the spline shaft 108 passes through the spline sleeve 104 and is connected to the drive assembly 109 to obtain rotational power. One end of the spline sleeve 104 passes through the sliding sleeve 103 and is connected to the polishing shaft 105 through the universal joint 110. The polishing head 106 is fixedly connected to the end of the polishing shaft 105 through the flange or thread. The polishing head 106 can be equipped with different polishing tools such as grinding wheels, cloth wheels, and polishing paste wheels as needed.

[0024] Please see Figure 4To adjust the working angle of the polishing head 106, a rotating shaft bracket 111 is provided in the middle of the polishing shaft 105. In this embodiment, the rotating shaft bracket 111 includes a U-shaped mounting bracket 301, a rotating block 302, and ball bearings 303. The rotating block 302 is fixedly connected to the middle of the polishing shaft 105. Ball bearings 303 are rotatably connected to the polishing shaft 105 on both sides of the rotating block 302. The ball bearings 303 are all fixedly connected to the U-shaped mounting bracket 301 through bearing seats. A connecting rod 112 is rotatably connected to one end of the U-shaped mounting bracket 301. The other end is hinged to the piston rod end of the first cylinder 107 via a pin. The cylinder body of the first cylinder 107 is fixedly connected to the outer wall of the sliding sleeve tube 103 via a mounting seat. By extending and retracting the piston rod of the first cylinder 107, the connecting rod 112 can be driven to swing, thereby driving the entire U-shaped mounting bracket 301 and the polishing shaft 105 connected to it via a bearing to deflect around the center point of the rotating block 302 within a certain angle range, thereby adjusting the angle of the polishing head 106 relative to the workpiece surface, so that the polishing head 106 can contact the workpiece surface, thereby realizing the workpiece surface polishing operation.

[0025] Please see Figure 5 The drive assembly 109 provides rotational power for the polishing head 106 and feed power for the translation plate 102. Its specific structure includes a support plate 401, a synchronous sprocket 402, a first small sprocket 403, a second small sprocket 404, a first large sprocket 405, a second large sprocket 406, a drive shaft 407, and a drive motor 408. One end of the side plate 101 is fixedly connected to the support plate 401. One end of the splined shaft 108 passes through a bearing seat on the support plate 401 and is fixedly connected to the synchronous sprockets 402. The synchronous sprockets 402 are interconnected via a closed synchronous chain or chain to ensure vertical rotation. Two splined shafts 108 rotate synchronously in the same direction. A first small sprocket 403 is coaxially fixedly connected to one side of the synchronous sprocket 402 located at the bottom (or designated as the drive shaft). The first small sprocket 403 is connected to the first large sprocket 405 through the first chain. The first large sprocket 405 is fixedly connected to the drive shaft 407. One end of the drive shaft 407 passes through the support plate 401 and is connected to the part clamping mechanism 2 to drive its rotation (see below for details). The other end of the drive shaft 407 is connected to the output shaft of the drive motor 408 through a coupling. The drive motor 408 is fixedly connected to the processing table 1 through a motor base.

[0026] Please see Figure 3 and Figure 5To drive the translation plate 102 to move, a second small sprocket 404 is fixedly connected to the drive shaft 407 on the other side of the support plate 401. The second small sprocket 404 is connected to the second large sprocket 406 via a second chain. The second large sprocket 406 is fixedly connected to a threaded rod 409. One end of the threaded rod 409 is rotatably connected to the support plate 401 via a bearing. A threaded hole 410 is opened at one end of the translation plate 102 (corresponding to the position of the threaded rod 409), and the threaded rod 409 is threadedly connected to the threaded hole 410. Within 0, when the drive motor 408 starts, the power is transmitted through the drive shaft 407, the second small sprocket 404, and the second chain to the second large sprocket 406, which drives the threaded rod 409 to rotate. Since the threaded rod 409 engages with the threaded hole 410 on the translation plate 102, and the translation plate 102 is restricted by the sliding member to only move in a straight line, the rotational motion of the threaded rod 409 is converted into the linear feed or retraction motion of the translation plate 102 along the sliding rail 201, thereby realizing the gradual or reciprocating movement of the polishing head 106 relative to the workpiece.

[0027] Example 2 Based on Embodiment 1, to further optimize the working environment and collect the dust generated during polishing, the polishing device of the present invention also includes a dust collection system 4. Please refer to Embodiment 1. Figure 6 The dust collection system 4 includes a mounting plate 501, a dust collection box 502, a vacuum cleaner 503, a suction pipe 504, and a clamp assembly 505. The mounting plate 501 is fixedly connected to the upper end of the side plate 101, and the dust collection box 502 is fixedly connected to the upper end of the mounting plate 501. The vacuum cleaner 503 is fixedly connected to the mounting plate 501 on one side of the dust collection box 502. The outlet end of the vacuum cleaner 503 is connected to the inside of the dust collection box 502 via a pipe, and its inlet end is connected to the suction pipe 504 via a flexible hose. The suction pipe 504... 04 is fixedly connected to the clamp assembly 505 via the connecting rod 508. The clamp assembly 505 is fixedly connected to the cylinder body of the first cylinder 107, so that it can move synchronously with the movement of the polishing head 106 component. The other end of the dust suction pipe 504 is connected to the gooseneck pipe 506. The other end of the gooseneck pipe 506 is fixedly connected to the dust suction hood 507. The dust suction hood 507 is set on the side or obliquely above the polishing head 106, and its opening faces the contact area between the polishing head 106 and the workpiece, so as to efficiently suck up dust.

[0028] Please see Figure 7Specifically, the clamp assembly 505 includes an upper clamp 601, a lower clamp 602, a connecting plate 603, and a rubber pad 604. The two ends of the first cylinder 107 (located at both ends of the cylinder body) are respectively connected by an upper clamp 601 and a lower clamp 602 to form a clamp structure. The two ends of the upper clamp 601 extend outward to form a fastening plate 605, and the two ends of the lower clamp 602 extend outward to form a fixing plate 606. During installation, the upper clamp 601 and the lower clamp 602 are wrapped around the first cylinder 107, so that the fastening plate 605 is aligned with the corresponding fixing plate 606. Then, a connecting plate 603 is placed between the fastening plate 605 and the fixing plate 606, and rubber pads 604 are placed between the connecting plate 603 and the fastening plate 605, and between the connecting plate 603 and the fixing plate 606. Finally, bolts 607 are passed through the four parts and nuts 608 are used to tighten them. The connecting rod 508 of the dust suction pipe 504 is fixedly connected to the middle of the upper clamp 601 or the lower clamp 602.

[0029] Example 3 Based on Embodiment 1, the specific structure of the part clamping mechanism 2 is as follows: Please see Figure 8 The part clamping mechanism 2 includes a mounting platform 701, a bottom liner 702, a clamping plate 703, and a second cylinder 704. The lower end of the mounting platform 701 is fixedly connected to the processing table 1. The bottom liner 702 is fitted into the middle of the upper end of the mounting platform 701. The upper surface of the bottom liner 702 is used to support the workpiece. To facilitate the rotational polishing of cylindrical, shaft-like, and other parts, several rotating grooves 705 are provided on the bottom liner 702. Each rotating groove 705 is rotatably connected to a bottom guide roller 706 via a short shaft. The guide roller 706 is fixedly connected to the rotating shaft. One end of the rotating shaft passes through the side of the bottom liner plate 702 and is fixedly connected to a transmission gear 707. On the same side of the bottom liner plate 702, on the same side as the transmission gear 707, several linkage gears 708 are rotatably connected via shaft seats. The linkage gears 708 are meshed with adjacent transmission gears 707. A rotating shaft located in the middle passes through the bottom liner plate 702, and its end is fixedly connected to the end of the drive shaft 407 via a coupling or key. Therefore, when the drive motor 408 is running, the drive shaft 407 can drive the rotating shaft in the middle and the transmission gear 707 to rotate. Then, through the meshing linkage gears 708, the power is transmitted to all other transmission gears 707, thereby driving all the bottom liner guide rollers 706 to rotate synchronously and in the same direction, causing the workpiece placed on them to rotate.

[0030] Please see Figure 8The bottom liner 702 has two sides (or positions corresponding to the ends of the workpiece) hinged to clamping plates 703 via hinge shafts. The opposite sides (outer sides) of the clamping plates 703 are hinged to second cylinders 704 via pins. The cylinder ends of the second cylinders 704 are hinged to the two sides of the mounting platform 701 via supports. The synchronous extension and retraction of the two second cylinders 704 drives the clamping plates 703 on both sides to rotate around their hinge points with the bottom liner 702, thereby clamping (holding) or releasing (releasing) the workpiece placed on the bottom guide rollers 706. To reduce friction and assist workpiece rotation, the inner side (facing the workpiece) of the clamping plates 703 has several rotating shaft grooves 709. Each rotating shaft groove 709 is rotatably connected to a side guide roller 710 via a short shaft. When the clamping plates 703 close to clamp the workpiece, the side guide rollers 710 contact the side of the workpiece, providing clamping force and allowing the workpiece to roll during rotation, reducing resistance.

[0031] The working principle of this invention is as follows: Please see Figures 1-8 During operation, the workpiece to be polished (such as a long shaft) is placed horizontally on the bottom guide rollers 706 of the workpiece clamping mechanism 2. The two second cylinders 704 are activated, extending their piston rods and causing the side clamping plates 703 to close inwards, clamping the workpiece via the side guide rollers 710. The drive motor 408 is then activated, transmitting power in three paths: one path drives all the bottom guide rollers 706 of the workpiece clamping mechanism 2 to rotate synchronously via the drive shaft 407, driving the workpiece to rotate around its axis; the second path drives the two splined shafts via the first small sprocket 403, the first large sprocket 405, and the synchronous sprocket 402 system. The polishing head 106 rotates synchronously, and the power is transmitted to the polishing shaft 105 via the spline sleeve 104 and universal joint 110, ultimately driving the polishing head 106 to rotate at high speed. The third path drives the threaded rod 409 to rotate via the second small sprocket 404 and the second large sprocket 406, causing the translation plate 102 and the entire polishing head 106 assembly to move slowly along the workpiece axis. By controlling the first cylinder 107, the angle of the polishing head 106 can be adjusted so that it can contact the workpiece surface. As the rotating polishing head 106 moves along the workpiece axis, it performs progressive and uniform polishing on the rotating workpiece surface. At the same time, the dust collection system 4 is activated, and the dust suction hood 507 approaches the polishing point, sucking in the generated dust and collecting it into the dust collection box 502 via the dust suction pipe 504 and the vacuum cleaner 503.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
