Description

Technical Field

[0001] This invention relates to the field of surface treatment equipment technology, and in particular to a high-efficiency surface treatment device and process for precision parts. Background Technology

[0002] Precision components are widely used in industries such as automotive, telecommunications, medical, watchmaking, mobile phones, and computers. Unlike ordinary components, precision components are more precise and better suited for industries with high accuracy requirements. Precision component grinding equipment plays a crucial role in people's lives. Grinding is applied in various automated industries to remove burrs generated after component processing, optimizing components to make them more aesthetically pleasing and practical.

[0003] An existing high-efficiency precision parts surface treatment device (publication number: CN114536135A) has at least the following drawbacks:

[0004] When the above-mentioned patent is used, workpieces of different sizes are effectively clamped by the cooperation of a servo motor, a bidirectional threaded rod, a threaded sleeve, a moving track, and a T-shaped clamping plate. Then, the upper surface of the part is polished by the grinding disc above. Since the above patent can only polish the upper surface of the part, the inner wall and other outer surfaces of the part need to be polished multiple times. Polishing the inner and outer surfaces of the part multiple times will increase the time and cost of surface treatment and greatly reduce production efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the prior art, only the upper surface of the part can be polished, while the inner wall and other outer surfaces of the part need to be polished multiple times. Polishing the inner and outer surfaces of the part multiple times will increase the time and cost of surface treatment and greatly reduce production efficiency. Therefore, this invention proposes a high-efficiency precision parts surface treatment device and process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency precision component surface treatment device and process includes a worktable and multiple legs equidistantly fixed on the outer circumference of the worktable.

T-shaped arc sliders are slidably mounted on the inner walls of each T-shaped arc groove. A second rotating shaft is rotatably mounted on the upper surface of each T-shaped arc slider. A V-shaped drive wheel is fixedly mounted on the outer surface of the second rotating shaft near its top. A circular workpiece is rolled between the V-shaped drive wheels. A third rotating shaft is rotatably mounted on the upper surface of the worktable. A first polishing wheel is fixedly mounted on the outer surface of the top of the third rotating shaft. The outer surface of the first polishing wheel has a contour groove matching the shape of the circular workpiece. A mounting bracket is fixedly mounted on the inner wall of the worktable. A first rotating shaft is rotatably mounted on the upper surface of the mounting bracket. A second polishing wheel is fixedly mounted on the outer surface of the top of the first rotating shaft. The second polishing wheel abuts against the inner wall of the circular workpiece, and the contour groove on the outer surface of the first polishing wheel abuts against the outer surface of the circular workpiece.

[0008] As a further embodiment of the present invention, a rotating ring is rotatably mounted on the lower surface of the worktable, and a plurality of arc-shaped limiting grooves are equidistantly opened in the circumferential direction on the lower surface of the rotating ring. A plurality of limiting posts are fixedly installed equidistantly in the circumferential direction on the lower surface of the worktable, and the limiting posts are slidably installed with the inner wall of the arc-shaped limiting grooves.

[0009] As a further embodiment of the present invention, a fixing sleeve is fixedly installed on the lower surface of the T-shaped arc slider, and multiple driving grooves are equidistantly opened in the circumferential direction on the lower surface of the rotating ring. The fixing sleeve is slidably installed with the inner wall of the driving groove, and the center line of the driving groove passes through the center of the T-shaped arc groove.

[0010] As a further embodiment of the present invention, a drive column is fixedly installed on the outer circumference of the rotating ring, and a cylinder is rotatably installed on the outer surface of one of the legs, with the telescopic end of the cylinder rotatably installed with one end of the drive column.

[0011] As a further embodiment of the present invention, a plurality of support blocks are fixedly installed at equal intervals on the inner wall of the rotating ring, and a fifth gear is rotatably installed on the lower surface of each of the plurality of support blocks. A second pulley is fixedly installed on the lower surface of the rotation center of the fifth gear, and a first pulley is fixedly installed through the inner wall of the fixed sleeve at the bottom end of the second rotating shaft. A belt is sleeved on the outer surface of the first pulley and the second pulley.

[0012] As a further embodiment of the present invention, a base plate is fixedly installed between the legs, the base plate is located below the rotating ring, a first gear is rotatably installed on the upper surface of the base plate, a drive motor is fixedly installed on the lower surface of the base plate, the output end of the drive motor passes through the upper surface of the base plate and is fixedly installed with the rotation center of the first gear, the first gear meshes with a fifth gear, a second gear is fixedly installed on the upper surface of the rotation center of the first gear, and a third gear is fixedly installed at the bottom end of the first rotating shaft through the lower surface of the mounting bracket, the third gear meshes with the second gear.

[0013] As a further embodiment of the present invention, a fourth gear is fixedly installed at the bottom end of the third rotating shaft through the lower surface of the worktable. The fourth gear meshes with an adjacent fifth gear. A notch is provided on the outer surface of the rotating ring near the fourth gear, and the fourth gear is disposed inside the notch.

[0014] As a further embodiment of the present invention, the T-shaped arc groove and the fifth gear are located at the same center.

[0015] A high-efficiency surface treatment process for precision parts includes the following steps:

[0016] S1: When installing the ring workpiece, the operator inserts one side of the ring workpiece into the contour groove of the first polishing wheel, and then places the ring workpiece between several V-shaped drive wheels.

[0017] S2: The extension movement of the cylinder extension end causes the drive column to drive the rotating ring to rotate. The rotating ring drives the T-shaped arc slider to move closer to each other along the T-shaped arc groove through the drive groove and the fixed sleeve. The T-shaped arc slider drives the V-shaped drive wheel to move closer to each other through the second rotating shaft. The V-shaped drive wheel clamps the ring workpiece in its V-shaped opening.

[0018] S3: The first gear is driven to rotate by the drive motor. The first gear drives the second pulley to rotate through the fifth gear. The second pulley drives the first pulley to rotate through the belt. The first pulley drives the V-type drive wheel to rotate in the same direction through the second rotating shaft. The V-type drive wheel drives the circular workpiece to rotate, so that the first polishing wheel and the second polishing wheel can polish and grind its outer surface evenly.

[0019] S4: The fifth gear drives the fourth gear to rotate, which in turn drives the first polishing wheel to rotate via the third shaft. At the same time, the first gear drives the second gear to rotate, which in turn drives the first shaft to rotate via the third gear. This causes the first shaft to drive the second polishing wheel to rotate. The rotation of the first polishing wheel polishes the outer surface of the circular workpiece, while the rotation of the second polishing wheel polishes the inner wall of the circular workpiece.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] A V-shaped drive wheel rotates the annular workpiece, allowing the first and second polishing wheels to evenly polish its outer surface. A fifth gear drives a fourth gear, which in turn drives the first polishing wheel via a third shaft. Simultaneously, the first gear drives the second gear, which in turn drives the first shaft via the third gear. This shaft then drives the second polishing wheel. The rotation of the first polishing wheel polishes the outer surface of the annular workpiece, while the rotation of the second polishing wheel polishes its inner surface. This device ensures that both the inner and outer surfaces of the annular workpiece can be polished simultaneously, avoiding the time and cost associated with multiple polishing processes and thus improving production efficiency.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Reference Figures 1-9A high-efficiency precision parts surface treatment device and process includes a worktable 1 and multiple support legs 2 equidistantly fixed on the outer circumference of the worktable 1. Multiple T-shaped arc grooves 17 are equidistantly opened along the circumference of the upper surface of the worktable 1. T-shaped arc sliders 18 are slidably mounted on the inner walls of each T-shaped arc groove 17. A second rotating shaft 19 is rotatably mounted on the upper surface of the T-shaped arc slider 18. A V-shaped drive wheel 9 is fixedly mounted on the outer surface of the second rotating shaft 19 near its top. A circular workpiece 6 is rolled between the V-shaped drive wheels 9. A third rotating shaft 20 is rotatably mounted on the upper surface of the worktable 1. A first polishing wheel 7 is fixedly mounted on the outer surface of the top end of the third rotating shaft 20. The outer surface of the first polishing wheel 7 has a contour groove that matches the shape of the annular workpiece 6. A mounting bracket 15 is fixedly mounted on the inner wall of the worktable 1. A first rotating shaft 16 is rotatably mounted on the upper surface of the mounting bracket 15. A second polishing wheel 8 is fixedly mounted on the outer surface of the top end of the first rotating shaft 16. The second polishing wheel 8 abuts against the inner wall of the annular workpiece 6, and the contour groove on the outer surface of the first polishing wheel 7 abuts against the outer surface of the annular workpiece 6.

[0036] The fifth gear 26 drives the fourth gear 21 to rotate, which in turn drives the first polishing wheel 7 to rotate via the third shaft 20. Simultaneously, the first gear 12 drives the second gear 13 to rotate, which in turn drives the first shaft 16 to rotate via the third gear 14. This causes the first shaft 16 to rotate, which in turn drives the second polishing wheel 8 to rotate. The rotation of the first polishing wheel 7 polishes the outer surface of the annular workpiece 6, while the rotation of the second polishing wheel 8 polishes the inner wall of the annular workpiece 6. This device ensures that the inner and outer surfaces of the annular workpiece 6 can be polished simultaneously, avoiding the time and cost of multiple polishing processes and improving production efficiency.

[0037] In this embodiment, a rotating ring 3 is rotatably mounted on the lower surface of the workbench 1. Multiple arc-shaped limiting grooves 23 are equidistantly opened in the circumferential direction on the lower surface of the rotating ring 3. Multiple limiting posts 24 are fixedly installed equidistantly in the circumferential direction on the lower surface of the workbench 1. The limiting posts 24 are slidably installed on the inner wall of the arc-shaped limiting grooves 23. A fixing sleeve 22 is fixedly installed on the lower surface of the T-shaped arc slider 18. Multiple driving grooves 25 are equidistantly opened in the circumferential direction on the lower surface of the rotating ring 3. The fixing sleeve 22 is slidably installed on the inner wall of the driving grooves 25. A driving post 4 is fixedly installed on the outer circumferential surface of the rotating ring 3. A cylinder 5 is rotatably mounted on the outer surface of one of the legs 2. The telescopic end of the cylinder 5 is rotatably installed with one end of the driving post 4.

[0038] In use, the operator inserts one side of the annular workpiece 6 into the contour groove of the first polishing wheel 7, and then places the annular workpiece 6 between several V-shaped drive wheels 9. The extension movement of the cylinder 5 causes the drive column 4 to drive the rotating ring 3 to rotate. The rotating ring 3 drives the drive groove 25 to rotate, so that the drive groove 25 drives the T-shaped arc slider 18 to move closer to each other along the T-shaped arc groove 17 through the fixed sleeve 22. The T-shaped arc slider 18 drives the V-shaped drive wheels 9 to move closer to each other through the second rotating shaft 19. The V-shaped drive wheels 9 clamp the annular workpiece 6 in its V-shaped opening. This device facilitates the clamping and fixing of the annular workpiece 6. Furthermore, the adjustable movement of the V-shaped drive wheels 9 and the V-shaped setting facilitate the clamping of annular workpieces 6 of different sizes.

[0039] In this embodiment, the center line of the drive groove 25 passes through the center of the T-shaped arc groove 17. This arrangement facilitates the drive groove 25 to drive the T-shaped arc slider 18 to slide along the T-shaped arc groove 17 through the fixing sleeve 22.

[0040] In this embodiment, multiple support blocks 30 are fixedly installed at equal intervals on the inner wall of the rotating ring 3. A fifth gear 26 is rotatably installed on the lower surface of each of the multiple support blocks 30. A second pulley 29 is fixedly installed on the lower surface of the rotation center of the fifth gear 26. A first pulley 27 is fixedly installed through the inner wall of the fixed sleeve 22 at the bottom end of the second rotating shaft 19. A belt 28 is sleeved on the outer surface of the first pulley 27 and the second pulley 29. A base plate 10 is fixedly installed between the support legs 2. The base plate 10 is located below the rotating ring 3. A first gear 12 is rotatably installed on the upper surface of the base plate 10. A drive motor 11 is fixedly installed on the lower surface of the base plate 10. The output end of the drive motor 11 is fixedly installed through the upper surface of the base plate 10 and at the rotation center of the first gear 12.

[0041] After clamping the circular workpiece 6, the drive motor 11 drives the first gear 12 to rotate, which in turn drives the fifth gear 26 to rotate. The fifth gear 26 then drives the second pulley 29 to rotate, which in turn drives the first pulley 27 to rotate via the belt 28. This causes the first pulley 27 to drive the second shaft 19 to rotate, which in turn drives the V-shaped drive wheel 9 to rotate in the same direction. The V-shaped drive wheel 9 then drives the circular workpiece 6 to rotate, which facilitates the uniform polishing of its outer surface by the first polishing wheel 7 and the second polishing wheel 8, ensuring consistent polishing.

[0042] In this embodiment, the first gear 12 and the fifth gear 26 mesh with each other. The second gear 13 is fixedly installed on the upper surface of the rotation center of the first gear 12. The bottom end of the first rotating shaft 16 passes through the lower surface of the mounting bracket 15 and the third gear 14 is fixedly installed. The third gear 14 meshes with the second gear 13. The first gear 12 drives the second gear 13 to rotate. The second gear 13 drives the first rotating shaft 16 to rotate through the third gear 14, so that the first rotating shaft 16 drives the second polishing wheel 8 to rotate.

[0043] In this embodiment, the bottom end of the third rotating shaft 20 is fixedly installed with a fourth gear 21 through the lower surface of the workbench 1. The fourth gear 21 meshes with an adjacent fifth gear 26. The fourth gear 21 is driven to rotate by one of the fifth gears 26, which in turn drives the third rotating shaft 20 to rotate. The third rotating shaft 20 then drives the first polishing wheel 7 to rotate.

[0044] In this embodiment, a notch is provided on the outer surface of the rotating ring 3 near the fourth gear 21, and the fourth gear 21 is disposed inside the notch. The notch facilitates the correct rotation of the rotating ring 3.

[0045] In this embodiment, the T-shaped arc groove 17 and the fifth gear 26 are located at the same center. By being located at the same center, it is ensured that the second pulley 29 can correctly drive the first pulley 27 to rotate through the belt 28.

[0046] In this embodiment, the outer circumferential surface of the V-shaped drive wheel 9 is provided with a V-shaped opening, which is convenient for clamping circular workpieces 6 of different sizes. The V-shaped drive wheel 9 is made of rubber, which can increase the friction between it and the circular workpiece 6, making it easier to drive the circular workpiece 6 to rotate. At the same time, the flexibility of the rubber can prevent the circular workpiece 6 from being squeezed and damaged.

[0047] In this embodiment, the first polishing wheel 7 and the second polishing wheel 8 are made of relatively soft polishing cotton, which has a certain degree of flexibility and can conform to the outer surface of the annular workpiece 6.

[0048] This embodiment includes the following steps:

[0049] S1: When installing the circular workpiece 6, the operator inserts one side of the circular workpiece 6 into the contour groove of the first polishing wheel 7, and then places the circular workpiece 6 between several V-shaped drive wheels 9.

[0050] S2: The extension movement of the cylinder 5 causes the drive column 4 to drive the rotating ring 3 to rotate. The rotating ring 3 drives the T-shaped arc slider 18 to move closer to each other along the T-shaped arc groove 17 through the drive groove 25 and the fixed sleeve 22. The T-shaped arc slider 18 drives the V-shaped drive wheel 9 to move closer to each other through the second rotating shaft 19. The V-shaped drive wheel 9 clamps the ring workpiece 6 in its V-shaped opening.

[0051] S3: The first gear 12 is driven to rotate by the drive motor 11. The first gear 12 drives the second pulley 29 to rotate through the fifth gear 26. The second pulley 29 drives the first pulley 27 to rotate through the belt 28. The first pulley 27 drives the V-type drive wheel 9 to rotate in the same direction through the second rotating shaft 19. The V-type drive wheel 9 drives the circular workpiece 6 to rotate, so that the first polishing wheel 7 and the second polishing wheel 8 can polish and grind the outer surface evenly, ensuring the consistency of grinding.

[0052] S4: The fifth gear 26 drives the fourth gear 21 to rotate, which in turn drives the first polishing wheel 7 to rotate via the third shaft 20. At the same time, the first gear 12 drives the second gear 13 to rotate, which in turn drives the first shaft 16 to rotate via the third gear 14. This causes the first shaft 16 to rotate, which in turn drives the second polishing wheel 8 to rotate. The rotation of the first polishing wheel 7 polishes the outer surface of the annular workpiece 6, while the rotation of the second polishing wheel 8 polishes the inner wall of the annular workpiece 6.

[0053] It should be noted that, in use, the operator inserts one side of the annular workpiece 6 into the contour groove of the first polishing wheel 7, and then places the annular workpiece 6 between several V-shaped drive wheels 9. The extension movement of the cylinder 5 causes the drive column 4 to rotate the rotating ring 3. The rotating ring 3 then rotates the drive groove 25, causing the drive groove 25 to move closer together along the T-shaped arcuate groove 17 via the fixed sleeve 22. The T-shaped arcuate slider 18, through the second rotating shaft 19, drives the V-shaped drive wheels 9 to move closer together, thus moving the annular workpiece 6 between the two wheels. The workpiece 6 is clamped within its V-shaped opening. This device facilitates the clamping and fixing of the circular workpiece 6. Furthermore, the adjustable movement of the V-shaped drive wheel 9 and the V-shaped design allow for the clamping of circular workpieces 6 of different sizes. After the circular workpiece 6 is clamped, the drive motor 11 drives the first gear 12 to rotate, which in turn drives the fifth gear 26 to rotate. The fifth gear 26 then drives the second pulley 29 to rotate, which in turn drives the first pulley 27 to rotate via the belt 28. This first pulley 27 then drives the second rotating shaft 19 to rotate, which in turn drives the V-shaped drive wheel 9 to rotate in the same direction. The V-shaped drive wheel 9 rotates the circular workpiece 6, facilitating uniform polishing of its outer surface by the first polishing wheel 7 and the second polishing wheel 8, ensuring consistent polishing. One of the fifth gears 26 drives the fourth gear 21, which in turn drives the third shaft 20. The third shaft 20 then drives the first polishing wheel 7. Simultaneously, the first gear 12 drives the second gear 13, which in turn drives the first shaft 16 via the third gear 14. This first shaft 16 then drives the second polishing wheel 8. The rotation of the first polishing wheel 7 polishes the circular workpiece 6. The outer surface of workpiece 6 is ground and polished, while the inner wall of the annular workpiece 6 is ground and polished by the rotation of the second polishing wheel 8. This device ensures that the inner and outer surfaces of the annular workpiece 6 can be ground and polished simultaneously, avoiding the problem of increasing the time and cost of surface treatment of the annular workpiece 6 by grinding multiple times, thus improving production efficiency. A dust suction head is set above the annular workpiece 6 to facilitate the adsorption of dust generated during grinding and polishing, preventing dust from spreading. After grinding is completed, the position restriction of the annular workpiece 6 can be released by the reverse movement of the cylinder 5, making it easy to replace the new annular workpiece 6.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
