Description

Technical Field

[0001] This invention belongs to the technical field of cookware polishing equipment, specifically a cookware surface fine grinding and polishing processing device. Background Technology

[0002] Currently, in the manufacturing process of cookware such as frying pans, fine grinding and polishing of the inner wall is a crucial surface treatment step. Its purpose is to remove machining marks, improve surface smoothness, and enhance the adhesion of non-stick coatings. In existing technology, for workpieces like frying pans with complex inner wall structures such as side walls, curved transition angles, and flat bottoms, traditional processing methods typically involve manual grinding with handheld polishing tools or sequential processing using a single-station dedicated machine.

[0003] Most equipment only has a single clamping station and a single polishing station. Clamping, positioning, polishing and unloading processes must be carried out sequentially at the same station, making it impossible to achieve synchronous operation of loading and polishing. This results in long downtime and low production efficiency, making it difficult to meet the needs of continuous mass production. Secondly, since the inner wall of the pan contains multiple areas with different geometric features, such as the side wall, the arc transition area and the flat bottom, existing equipment often uses a single-shaped polishing head to process multiple times and from multiple angles. After each processing, the workpiece posture or polishing tool position needs to be readjusted. This is not only cumbersome, but also the repeated clamping and positioning can easily produce seam marks or inconsistent polishing depths in adjacent processing areas, seriously affecting the consistency and smoothness of the overall surface quality of the inner wall. Summary of the Invention

[0004] The purpose of this invention is to enable the pan to circulate between the "loading-grinding and polishing-unloading" stations, allowing loading, unloading and polishing operations to be carried out simultaneously, which greatly improves continuous processing efficiency. At the same time, through the cooperation of the grinding and polishing mechanism and the cookware self-rotating clamping mechanism, the entire irregular inner wall can be ground and polished in one go. This avoids positioning errors caused by multiple clamping and ensures that the polishing of each area of ​​the inner wall is uniform and consistent, ultimately effectively improving processing quality and automated production efficiency.

[0005] The technical solution adopted in this invention is as follows: A cookware surface fine grinding and polishing processing device, comprising:

[0006] A base plate is provided, with a switching control box fixedly connected to its top. A switching transmission worm gear is rotatably connected between the switching control box and the base plate. A switching transmission worm is rotatably connected between the inner walls of both sides of the switching control box, and the switching transmission worm meshes with the switching transmission worm gear. A cross-shaped workstation plate is rotatably connected to the top of the switching control box, and the cross-shaped workstation plate is fixedly connected to the switching transmission worm gear. Two support rods are fixedly connected to the top of the base plate, and a top plate is fixedly connected to the upper ends of the two support rods.

[0007] Two sets of fine grinding and polishing mechanisms, both sets of which are located at the bottom of the top plate; and

[0008] Four sets of cookware self-rotating clamping mechanisms are all located on the top of the cross-shaped workstation plate.

[0009] The cookware self-rotating clamping mechanism includes a self-rotating control box, a supporting disc plate, a self-rotating transmission worm gear, a self-rotating transmission worm, a clamping control box, a bidirectional threaded rod, two clamping transmission blocks, and two clamping arc plates. The self-rotating control box is fixedly connected to the top of the cross-shaped workstation plate. The supporting disc plate is fixedly connected to the top of the self-rotating control box. The self-rotating transmission worm gear is rotatably connected between the supporting disc plate and the cross-shaped workstation plate. The self-rotating transmission worm is rotatably connected between the two inner walls of the self-rotating control box. The clamping control box is rotatably connected to the top of the supporting disc plate and is fixedly connected to the self-rotating transmission worm gear via a rotating shaft. The bidirectional threaded rod is rotatably connected between the two inner walls of the clamping control box. Both clamping transmission blocks are threadedly connected to the bidirectional threaded rod. Both clamping arc plates are slidably connected to the top of the clamping control box, and the two clamping arc plates are fixedly connected to the two clamping transmission blocks respectively.

[0010] The cookware self-rotating clamping mechanism also includes a drive motor, which is fixedly installed on one outer surface of the self-rotating control box, and the output end of the drive motor is fixedly connected to the self-rotating transmission worm gear.

[0011] The cookware self-rotating clamping mechanism also includes four supporting pulleys, which are fixedly installed at the bottom of the clamping control box and located at the top of the supporting disc plate.

[0012] The cookware self-rotating clamping mechanism also includes a servo motor, which is fixedly installed on one outer surface of the clamping control box, and the output end of the servo motor is fixedly connected to a bidirectional threaded rod.

[0013] The cookware self-rotating clamping mechanism also includes two limiting rods, both of which are fixedly connected between the inner walls of the two sides of the clamping control box, and each clamping transmission block is slidably sleeved on the two limiting rods.

[0014] The precision grinding and polishing mechanism includes an electric cylinder, a mounting frame, a cylindrical polishing head, and a flat polishing wheel. The electric cylinder is fixedly installed at the bottom of the top plate, and the top of the mounting frame is fixedly connected to the output end of the electric cylinder. The cylindrical polishing head and the flat polishing wheel are both rotatably connected to the bottom of the mounting frame.

[0015] The fine grinding and polishing mechanism also includes two polishing motors, both of which are fixedly installed on the inner bottom wall of the mounting frame. The output ends of the two polishing motors are fixedly connected to the cylindrical polishing head and the flat polishing wheel, respectively.

[0016] The fine grinding and polishing mechanism also includes two telescopic rods, both of which are fixedly installed between the top plate and the mounting frame.

[0017] A switching motor is fixedly installed on one side of the outer surface of the switching control box. The switching motor is fixedly installed on one side of the outer surface of the switching control box, and the output end of the switching motor is fixedly connected to the switching transmission worm gear.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, by controlling the start of the switching motor, the switching transmission worm gear is driven to rotate, which in turn drives the switching transmission worm wheel to rotate 90 degrees, thereby realizing the rotation switching of the cross-shaped workstation plate. This enables the four sets of cookware self-rotating clamping mechanisms to drive the corresponding flat-bottomed pans to circulate between the two feeding workstations and the two fine grinding and polishing workstations below the two sets of fine grinding and polishing mechanisms. When two sets of cookware self-rotating clamping mechanisms are fine grinding and polishing the two flat-bottomed pans at the fine grinding workstation, the other two sets of cookware self-rotating clamping mechanisms can simultaneously unload and re-clamp the flat-bottomed pans, effectively shortening the auxiliary working time, realizing continuous and rhythmic batch production, and significantly improving the overall processing efficiency.

[0020] (2) In this invention, the centering and clamping of the clamping arc plate under the drive of the bidirectional threaded rod and the clamping transmission block ensures the stability of the pan during the self-rotation process driven by the drive motor, the self-rotating transmission worm gear and the self-rotating transmission worm wheel to rotate the clamping control box. At the same time, after the cylindrical polishing head and the flat polishing wheel are lowered by the electric cylinder driving the mounting frame, they correspond to the inner side wall and the arc angle and the inner flat bottom wall of the pan, respectively. Combined with the uniform self-rotation of the pan body, the full coverage fine grinding and polishing of the irregular inner wall can be completed in one go. This avoids the positioning error caused by multiple clamping and ensures that the polishing of each area of ​​the inner wall is uniform and consistent, which ultimately effectively improves the processing quality and automated production efficiency.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] Example 1, refer to Figure 1-7 A cookware surface fine grinding and polishing processing device, comprising:

[0031] A base plate 1 is provided. A switching control box 2 is fixedly connected to the top of the base plate 1. A switching transmission worm gear 10 is rotatably connected between the switching control box 2 and the base plate 1. A switching transmission worm 9 is rotatably connected between the inner walls of both sides of the switching control box 2, and the switching transmission worm 9 is meshed with the switching transmission worm gear 10. A cross-shaped workstation plate 4 is rotatably connected to the top of the switching control box 2, and the cross-shaped workstation plate 4 is fixedly connected to the switching transmission worm gear 10. Two support rods 5 are fixedly connected to the top of the base plate 1, and a top plate 6 is fixedly connected to the upper end of the two support rods 5.

[0032] Two sets of fine grinding and polishing mechanisms 7 are provided, both of which are located at the bottom of the top plate 6; and

[0033] Four sets of cookware self-rotating clamping mechanisms 8 are all located on the top of the cross-shaped workstation plate 4.

[0034] In this implementation plan: the function of the fine grinding and polishing mechanism 7 is to achieve fine grinding and polishing of the inner wall of the frying pan without dead angles. The function of the cookware self-rotating clamping mechanism 8 is to clamp and fix the frying pan, and at the same time drive the frying pan to rotate so as to cooperate with the fine grinding and polishing mechanism 7 to perform comprehensive fine grinding and polishing. The lower position of the two sets of fine grinding and polishing mechanisms 7 is the fine grinding and polishing station. Two frying pans are loaded on the two sets of cookware self-rotating clamping mechanisms 8 that are not located in the fine grinding and polishing station. After the other two sets of frying pans located in the fine grinding and polishing station have been finely ground and polished, the switching transmission worm gear 9 will be controlled to rotate, driving the switching transmission worm wheel 10 to rotate 90 degrees. The two sets of cookware self-rotating clamping mechanisms 8 will drive the two frying pans into the lower side of the two sets of fine grinding and polishing mechanisms 7 for fine grinding and polishing processing. The other two sets of cookware self-rotating clamping mechanisms 8 that are detached from the fine grinding and polishing station will release the two frying pans, thereby unloading and reloading, and repeating the above process.

[0035] Specifically, the cookware self-rotating clamping mechanism 8 includes a self-rotating control box 801, a supporting disc plate 802, a self-rotating transmission worm gear 803, a self-rotating transmission worm 804, a clamping control box 806, a bidirectional threaded rod 808, two clamping transmission blocks 809, and two clamping arc plates 810. The self-rotating control box 801 is fixedly connected to the top of the cross-shaped workstation plate 4, the supporting disc plate 802 is fixedly connected to the top of the self-rotating control box 801, the self-rotating transmission worm gear 803 is rotatably connected between the supporting disc plate 802 and the cross-shaped workstation plate 4, and the self-rotating transmission worm 804... 04 is rotatably connected between the two inner walls of the self-rotating control box 801. The clamping control box 806 is rotatably connected to the top of the supporting disc plate 802, and the clamping control box 806 is fixedly connected to the self-rotating transmission worm gear 803 through the rotating shaft rod. The bidirectional threaded rod 808 is rotatably connected between the two inner walls of the clamping control box 806. The two clamping transmission blocks 809 are threadedly connected to the bidirectional threaded rod 808. The two clamping arc plates 810 are slidably connected to the top of the clamping control box 806, and the two clamping arc plates 810 are fixedly connected to the two clamping transmission blocks 809 respectively.

[0036] In this implementation plan, taking a set of cookware self-rotating clamping mechanisms 8 that are not initially in the fine grinding and polishing station as an example, the frying pan is placed on top of the clamping control box 806, simultaneously positioned between the two clamping arc plates 810. By controlling the rotation of the bidirectional threaded rod 808, the two clamping transmission blocks 809 are driven to move closer together, so that the two clamping arc plates 810 fix the frying pan. When the cross-shaped station plate 4 drives the set of cookware self-rotating clamping mechanisms 8 into the fine grinding and polishing station, the self-rotating transmission worm gear 804 is controlled to rotate, driving the self-rotating transmission worm wheel. Rotation of 803 causes the clamping control box 806 to rotate, which in turn causes the pan to rotate, making the pan fully contact the polishing parts of the fine grinding and polishing mechanism 7. After fine grinding and polishing, the cross-shaped workstation plate 4 causes the set of cookware self-rotating clamping mechanism 8 to leave the fine grinding and polishing workstation. At this time, the self-rotating transmission worm 804 stops rotating, and the bidirectional threaded rod 808 is controlled to rotate in the opposite direction, causing the two clamping transmission blocks 809 to move away from each other, so that the two clamping arc plates 810 release the pan, thereby unloading and reloading.

[0037] Specifically, the cookware self-rotating clamping mechanism 8 also includes a drive motor 805, which is fixedly installed on one side of the outer surface of the self-rotating control box 801, and the output end of the drive motor 805 is fixedly connected to the self-rotating transmission worm gear 804.

[0038] In this implementation scheme: the drive motor 805 is started by controlling the start of the drive motor, which drives the self-rotating transmission worm gear 804 to rotate.

[0039] Specifically, the cookware self-rotating clamping mechanism 8 also includes four support pulleys 807, which are all fixedly installed on the bottom of the clamping control box 806 and located on the top of the support disc plate 802.

[0040] In this implementation scheme: four support pulleys 807 move on the support disc plate 802 to support the clamping control box 806 without hindering the rotation of the clamping control box 806.

[0041] Specifically, the cookware self-rotating clamping mechanism 8 also includes a servo motor 811, which is fixedly installed on one side of the outer surface of the clamping control box 806, and the output end of the servo motor 811 is fixedly connected to the bidirectional threaded rod 808.

[0042] In this implementation scheme: the servo motor 811 is started by controlling it to drive the bidirectional threaded rod 808 to rotate.

[0043] Specifically, the cookware self-rotating clamping mechanism 8 also includes two limiting rods 812, which are fixedly connected between the inner walls of the two sides of the clamping control box 806, and each clamping transmission block 809 is slidably sleeved on the two limiting rods 812.

[0044] In this implementation scheme: the two limit rods 812 keep the two clamping transmission blocks 809 stable during relative movement.

[0045] Specifically, the fine grinding and polishing mechanism 7 includes an electric cylinder 701, a mounting bracket 702, a cylindrical polishing head 704, and a flat polishing wheel 705. The electric cylinder 701 is fixedly installed at the bottom of the top plate 6, the top of the mounting bracket 702 is fixedly connected to the output end of the electric cylinder 701, and the cylindrical polishing head 704 and the flat polishing wheel 705 are both rotatably connected to the bottom of the mounting bracket 702.

[0046] In this implementation scheme: when the two sets of cookware self-rotating clamping mechanisms 8 move the frying pan to the lower side of the two sets of fine grinding and polishing mechanisms 7, the two electric cylinders 701 will drive the two mounting brackets 702 to descend, so that the cylindrical polishing head 704 and the flat polishing wheel 705 on the lower side of each mounting bracket 702 enter the frying pan. By controlling the high-speed rotation of the cylindrical polishing head 704 and the flat polishing wheel 705 in each set of fine grinding and polishing mechanisms 7, the cylindrical polishing head 704 performs fine grinding and polishing on the inner side wall and the inner wall of the arc angle of the frying pan, and the flat polishing wheel 705 polishes the inner flat bottom wall of the frying pan. After polishing is completed, the electric cylinder 701 drives the mounting bracket 702 to rise, so that the finely ground and polished frying pan can leave the fine grinding and polishing station.

[0047] Specifically, the fine grinding and polishing mechanism 7 also includes two polishing motors 706. Both polishing motors 706 are fixedly installed on the bottom inner wall of the mounting bracket 702. The output ends of the two polishing motors 706 are fixedly connected to the cylindrical polishing head 704 and the flat polishing wheel 705 respectively.

[0048] In this implementation plan: In each set of fine grinding and polishing mechanisms 7, two polishing motors 706 control the cylindrical polishing head 704 and the flat polishing wheel 705 to rotate at high speed.

[0049] Specifically, the fine grinding and polishing mechanism 7 also includes two telescopic rods 703, both of which are fixedly installed between the top plate 6 and the mounting bracket 702.

[0050] In this implementation scheme: In each set of fine grinding and polishing mechanisms 7, two telescopic rods 703 ensure that the mounting frame 702 remains stable during lifting and moving.

[0051] Specifically, a switching motor 3 is fixedly installed on one side of the outer surface of the switching control box 2. The output end of the switching motor 3 is fixedly connected to the switching transmission worm gear 9.

[0052] In this implementation plan: the switching motor 3 is started by controlling the switching motor 3 to drive the switching transmission worm gear 9 to rotate.

[0053] Working principle: First, two frying pans are placed on the two sets of cookware self-rotating clamping mechanisms 8 located at the two grinding and polishing stations, respectively. The two corresponding servo motors 811 are started, driving the two corresponding bidirectional threaded rods 808 to rotate. Each pair of clamping transmission blocks 809 drives the corresponding two clamping arc plates 810 to move closer together, thus fixing the two frying pans on the two sets of cookware self-rotating clamping mechanisms 8. Then, the switching motor 3 is started, driving the switching transmission worm gear 9 to rotate, which in turn drives the switching transmission worm wheel 10 to rotate 90 degrees, causing the two sets of cookware self-rotating clamping mechanisms 8 containing the frying pans to enter the two sets of... On the lower side of the fine grinding and polishing mechanism 7, two drive motors 805 are started, driving two corresponding self-rotating transmission worm gears 804 to rotate, which in turn drives two corresponding self-rotating transmission worm wheels 803 to rotate, and then drives two corresponding clamping control boxes 806 to rotate. This causes two frying pans to rotate, and two electric cylinders 701 drive two mounting brackets 702 to descend. At the same time, four polishing motors 706 are started, driving two cylindrical polishing heads 704 and two flat polishing wheels 705 to rotate at high speed and enter the interior of the two frying pans. Through the rotation of the frying pans, the cylindrical polishing heads 704 perform thorough fine grinding and polishing on the inner side walls and the inner walls of the curved angle of the frying pans. The flat polishing wheel 705 thoroughly polishes the inner wall of the flat bottom of the pan. After polishing, the two electric cylinders 701 drive the two mounting brackets 702 to rise, and then the switching transmission worm gear 9 continues to rotate, driving the switching transmission worm wheel 10 to rotate another 90 degrees. The cross-shaped workstation plate 4 drives the two sets of cookware self-rotating clamping mechanisms 8 to leave the two fine grinding and polishing workstations. At this time, the self-rotating transmission worm gear 804 stops rotating, and the bidirectional threaded rod 808 is controlled to rotate in the opposite direction, driving the two clamping transmission blocks 809 to move relatively away, so that the two clamping arc plates 810 release the pan, thereby unloading the pan. Then the above process is repeated, through the cross-shaped workstation plate 4. The rotation switching enables the four sets of cookware self-rotating clamping mechanisms 8 to circulate between the "loading-fine grinding and polishing-unloading" stations, allowing loading and unloading and polishing operations to be carried out simultaneously, greatly improving continuous processing efficiency. At the same time, after the cylindrical polishing head 704 and the flat polishing wheel 705 are lowered by the electric cylinder 701 driving the mounting frame 702, they respectively fit the inner side wall, the inner wall of the curved angle, and the inner wall of the flat bottom of the pan. Combined with the rotation of the pan itself, the full-coverage fine grinding and polishing of the irregular inner wall can be completed in one go. This avoids the positioning errors caused by multiple clamping and ensures that the polishing of each area of ​​the inner wall is uniform and consistent, ultimately effectively improving processing quality and automated production efficiency.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
