Description
Technical Field
[0001] This invention belongs to the technical field of watch case processing equipment, and particularly relates to a polishing device for processing stainless steel watch cases. Background Technology
[0002] In the field of precision manufacturing, stainless steel watch cases are core components of high-end watches, and their surface finish and processing efficiency directly affect product quality and market competitiveness.
[0003] Traditional watch case polishing has long relied on manual operation. Workers need to hold the watch case and use tools such as sandpaper and polishing wheels to polish it repeatedly, which has significant drawbacks: manual polishing is inefficient and cannot meet the needs of large-scale production; at the same time, the operation is inconsistent and the surface finish is uneven due to differences in worker experience, and even scratches or over-polishing may occur, which significantly affects the product yield and appearance quality.
[0004] With technological advancements, existing technologies have shifted towards using mechanical equipment to replace manual polishing. For example, robotic arms hold watch cases and work with rotating polishing wheels to automate the process. While such equipment improves processing efficiency and consistency, it still has significant limitations: current polishing equipment typically can only handle a single watch case at a time, unable to process multiple workpieces simultaneously. In mass production scenarios, this single-piece processing mode leads to low equipment utilization, and frequent material loading / unloading and waiting times significantly extend the overall production cycle, severely restricting capacity expansion. Furthermore, the single-clamping method increases equipment idle time, resulting in energy waste and increased production costs.
[0005] Therefore, the current stainless steel watch case polishing industry urgently needs an innovative device that can break through the limitations of traditional single-piece processing, realize the simultaneous batch processing of multiple materials, significantly improve production efficiency, reduce energy consumption, and meet the dual demands of precision and efficiency for the high-end watch manufacturing industry.

[0036] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0037] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.
[0038] Examples, such as Figures 1-15 As shown, a polishing device for processing stainless steel watch cases includes a polishing device body, which includes a worktable 1. A material storage component integrating receiving and feeding functions is located on the front upper side of the worktable 1. A material transfer component integrating clamping and feeding functions is located on the rear upper upper side of the worktable 1. This component allows adjustment of the position of the clamped workpiece material to facilitate polishing when it is close to the grinding component. Furthermore, a material guide hood is provided on the worktable 1 on the side of the material transfer component to receive the processed workpiece and guide its discharge direction. That is, when the workpiece clamped by the clamping mechanism 7 moves to a position close to the material guide hood, the material on the clamping mechanism 7 is guided through the material guide hood to the external workpiece placement area for convenient collection. A grinding component is located on the worktable 1 on the side of the material storage component. The material storage component includes a rotating disk 2, on which a material holding mechanism 3 is provided to receive batches of materials in sequence, ensuring the stability of their placement position. The material holding mechanism 3 is equipped with a rotating opening and closing drive mechanism 4 on its outer side. On the one hand, it can provide driving power to the material holding mechanism 3, and on the other hand, it can reverse the driving power to act on the tilting mechanism 10. The tilting mechanism 10 can tilt the batch of materials, placing them at an inclined angle to ensure the comprehensiveness of the workpiece grinding and polishing and reduce polishing dead corners. The worktable 1 located below the material holding mechanism 3 is equipped with a material lifting mechanism 5, which can push out the tilting mechanism 10 carrying materials and, with the cooperation of the clamping mechanism 7, clamp the placed batch of materials and transport them towards the grinding mechanism 9 to ensure the smooth progress of the grinding work. The material transfer component includes a three-axis moving component 6, and the output end of the three-axis moving component 6 is equipped with a clamping mechanism 7 to stably clamp the batch of materials to ensure the smooth progress of the processing work. The grinding component includes a two-axis moving component 8, and the moving end of the two-axis moving component 8 is equipped with a grinding mechanism 9, which can perform comprehensive grinding of the workpiece from the top and bottom sides to ensure the comprehensiveness of the processing and improve the work process.
[0039] In the above process: the established material storage components include a material holding mechanism 3 that can receive batches of materials in sequence, ensuring the stability of their placement; a tilting mechanism 10 that can tilt the batches of materials, placing them at an angle to ensure the comprehensiveness of workpiece grinding and polishing and reduce polishing dead corners; and a material ejection mechanism 5 that can eject the tilting mechanism 10 carrying the materials, and with the cooperation of the clamping mechanism 7, clamp the placed batches of materials and transport them towards the grinding mechanism 9 to ensure the smooth progress of the grinding work. The established grinding mechanism 9 can perform comprehensive grinding of the workpiece from both the top and bottom, ensuring the comprehensiveness of the processing and improving the work process. This device is reasonably designed, simple in structure, and easy to process, breaking through the current limitations of single-piece processing. It can receive batches of materials and realize the synchronous batch processing of multiple materials, significantly improving production efficiency, reducing energy consumption, improving the functionality of the equipment, and effectively meeting the needs of users.
[0040] To improve the rationality of the device setup and facilitate convenient adjustment of the workpiece's position, the three-axis moving assembly 6 includes a longitudinal rodless drive cylinder 61. A longitudinal slide bar 62 is provided on one side of the longitudinal rodless drive cylinder, and a sliding block is provided on the longitudinal slide bar 62 to facilitate the longitudinal movement and adjustment of the device components. A vertical slide bar 63 is provided at the output end of the longitudinal rodless drive cylinder 61, and a sliding block is also provided on it to facilitate the vertical movement and adjustment of the device components. A vertical rodless drive cylinder 64 is provided above the longitudinal slide bar 62. A vertical moving plate 65 is provided at the moving end of the vertical rodless drive cylinder 64 and on the vertical slide bar 63. A transverse rodless drive cylinder 66 is provided on the vertical moving plate 65. A horizontal slide bar 67 is provided below the device, and a horizontal sliding plate 68 is provided on the output end of the horizontal rodless drive cylinder 66 and the horizontal slide bar 67. Specifically, the vertical rodless drive cylinder 61 can drive the device to move and adjust in the vertical direction, while the vertical rodless drive cylinder 64 can drive the device to lift and lower in the vertical direction, providing convenience for the clamping mechanism 7 to pick up and put down workpieces. The horizontal rodless drive cylinder 66 provides convenient conditions for the horizontal movement and adjustment of the clamping mechanism 7. It can both transport the workpiece held by the clamping mechanism 7 to the grinding mechanism 9 and output the ground workpiece out of the device, thereby improving the functionality of the device and meeting the usage requirements.
[0041] To clamp batches of materials and ensure smooth subsequent processing, the clamping mechanism 7 includes a rotating frame 71. A first driven gear 72 is located on the rear side of the rotating frame 71, and a first driving gear 73 is located on one side of the first driven gear 72. The first driving gear 73 receives external driving power and meshes with the first driven gear 72. The rotation of the first driven gear 72 drives the rotating frame 71 to rotate circumferentially. In particular, when the clamping mechanism 7 clamps the tilting mechanism 10 carrying the workpiece, it rotates it counterclockwise. When it rotates to a horizontal position, the three-axis moving assembly 6 is controlled to move the workpiece closer to the polishing mechanism 9, so that the workpiece completes the corresponding polishing treatment. After one side of the processing is completed, the rotating frame 71 can be rotated in the opposite direction to adjust the processing surface of the workpiece and ensure the overall polishing of the workpiece. A mounting plate 74 is located on the front side of the rotating frame 71, and a fixing plate 75 is located below the front side of the mounting plate 74. A first finger cylinder 76 is provided on the fixed plate 75. A vertical limiting slide bar 77 is provided on the upper front side of the mounting plate 74. A vertical plate 78 is provided on the two vertical limiting slide bars 77. A second finger cylinder 79 is provided on the front side of the vertical plate 78. A vertical drive cylinder 710 is provided on the upper part of the mounting plate 74 and connected to the vertical plate 78. Specifically, the first finger cylinder 76 is positioned relatively constant and mainly clamps the lower end of the tilting mechanism 10 that holds the material. The second finger cylinder 79 can be adjusted up and down under the drive of the vertical drive cylinder 710. The second finger cylinder 79 can clamp the upper end of the tilting mechanism 10 and adjust the vertical position of the device to meet different usage requirements. During use, the tilting mechanism 10 is adjusted vertically relative to the fixed plate 75 to facilitate the cooperation between its lower end and the auxiliary drive mechanism 11, providing a prerequisite for the workpiece to be unloaded after processing and meeting usage requirements.
[0042] To facilitate the convenient acceptance of workpieces to be processed and the convenient export of workpieces after batch processing, the material holding mechanism 3 includes a positioning plate 31 with a concave cross-section, mounted on a rotating disk 2. A fixed disk 32 is installed inside the positioning plate 31, and a positioning post 33 is installed on the fixed disk 32. A sector-shaped plate 34 is installed outside the positioning post 33, and a vertical rod 35 is installed above the sector-shaped plate 34. A ring-shaped transfer frame 36 is installed inside the positioning plate 31, located outside the fixed disk 32. A keyway 361 is formed inside the ring-shaped transfer frame 36, and a limit post 37 is installed inside the positioning plate 31 corresponding to the keyway 361. A connecting rod is installed on the upper inner side of the ring-shaped transfer frame 36. Key 38, one end of which is rotatably connected to the outer side of sector plate 34. A notch 311 is provided on the outer side of positioning disk 31. A connecting plate 312 is provided on the outer side of the ring-moving frame 36 located at the notch 311. An arc-shaped rack 39 is provided on the outer side of the connecting plate 312. Specifically, the sector plates 34, when fitted together, form a disk shape design, and an arc-shaped hole is provided at its geometric center, which is adapted to the sleeve 102 in the tilting mechanism 10. The geometric center of the positioning disk 31 facilitates the placement of the tilting mechanism 10. During use, the drive gear 41 in the rotating opening and closing drive mechanism 4 rotates and acts on the arc-shaped rack 39. After receiving the driving power, the rotation will act on the connecting rod. At this time, the ring shifter 36 will rotate relative to the positioning plate 31 along with the connecting rod and under the action of the limiting post 37. The rotation of the ring shifter 36 will act on the connecting key 38. After receiving the driving power, the connecting key 38 will pull the sector plate 34 to rotate relative to the fixed plate 32. At this time, each upright 35 placed on the sector plate 34 will open in a way that rotates outward, especially providing sufficient clamping space for the tilting mechanism 10 placed in the material holding mechanism 3. That is to say, the tilting mechanism 10 placed in the material holding mechanism 3 is stably placed under the limiting of the material holding mechanism 3, and at the same time receives the driving power. After external processing, the workpieces are placed one by one onto the sleeve 102. The upright 35 in the material holding mechanism 3 limits the placement position of the workpieces to ensure their relative accuracy. When the workpiece is removed, the material holding mechanism 3 is opened by the rotation opening and closing drive mechanism 4, and the upright 35 is also opened. The clamping mechanism 7 clamps the tilting mechanism 10, making it easier to remove the material. Furthermore, when the material on the tilting mechanism 10 is processed and discharged, and then put back, the material holding mechanism 3 is closed, and the position of the tilting mechanism 10 is limited to prevent it from shifting, thus providing convenient conditions for receiving subsequent materials.
[0043] To ensure effective transmission of driving power, the rotary opening and closing drive mechanism 4 includes a drive gear 41 that meshes with an arc-shaped rack 39. A rotating shaft 42 is located below the drive gear 41. A sleeve shaft 43 is located outside the rotating shaft 42. A drive wheel 44 is located outside the sleeve shaft 43. A first bevel gear 45 is located below the drive wheel 44. A second bevel gear 46 is located on the rotating shaft 42 below the first bevel gear 45. An I-shaped lifting sleeve 47 is located on the rotating shaft 42 between the first bevel gear 45 and the second bevel gear 46. A semi-circular clamping sleeve 48 is located outside the lifting sleeve 47. A support rod 481 is located on one side of the clamping sleeve 48. A housing 49 is located outside the rotating shaft 42. A... A third bevel gear 410 is provided on the side and connected to the support rod 481. A lifting block 411 is provided at the connection between the third bevel gear 410 and the housing 49. An electromagnetic push rod 412 is provided on the outside of the housing 49, and its output end is connected to the lifting block 411. A driven wheel 413 is provided on the rotating disk 2 located below the material holding mechanism 3. A first connecting sleeve 414 is provided above the driven wheel 413. An internal hexagonal hole is opened in the first connecting sleeve 414. Specifically, the established rotation opening and closing drive mechanism 4 can realize convenient switching of drive power to reduce the redundancy of the equipment. The rotating shaft 42 and the sleeve shaft 43 can rotate relative to each other. When it is necessary to control the opening and closing of the material holding mechanism 3, the electromagnetic push rod 412 is controlled to run, so as to push it. As the lifting block 411 and the third bevel gear 410 move downwards and mesh with the second bevel gear 46, the third bevel gear 410 is controlled to rotate. The second bevel gear 46 receives the driving power and acts on the rotating shaft 42, driving the drive gear 41 to rotate. This allows the material holding mechanism 3 to open, providing a prerequisite for the removal of the tilting mechanism 10. When it is necessary to control the tilting mechanism 10 to operate, especially to tilt and swing the position of the batch of workpieces, the control of the electromagnetic push rod 412 is disconnected, causing the lifting block 411 to move in the opposite direction and the third bevel gear 410 to mesh with the first bevel gear 45. Then, the third bevel gear 410 is controlled to rotate, the first bevel gear 45 receives the driving power, and the drive wheel 44 follows. The drive wheel 44 and the driven wheel 413 are connected by a synchronous belt to ensure the transmission of driving power. The rotation of the driven wheel 413 can drive the first connecting sleeve 414 to rotate, which in turn will act on the tilting mechanism 10, causing it to rotate and thus drive the tilting mechanism 10 to operate, ensuring that the workpiece is tilted. In other words, the lifting sleeve 47 moves vertically relative to the rotating shaft 42 and rotates together with the rotating shaft 42. The abutting sleeve 48 is placed inside the lifting sleeve 47 and the two can slide relative to each other. The support rod 481 on one side of the abutting sleeve 48 is rotatably set with the third bevel gear 410 and can be adjusted vertically with the lifting block 411 to ensure the smooth operation of the driving power reversal.
[0044] To ensure the smooth progress of workpiece polishing, considering that when batches of workpieces are placed on receiving workpieces such as rods, adjacent workpieces may come into contact, creating polishing dead zones and compromising the overall polishing effect, a tilting mechanism 10 is provided within the material holding mechanism 3. The tilting mechanism 10 includes an annular plate 101 located within the positioning disk 31, a sleeve 102 positioned above the annular plate 101, a ball screw 103 housed within the sleeve 102, and multiple equally spaced, tapered screw nut seats 104 arranged symmetrically on the outer side of the ball screw 103. The connection between these seats and the ball screw 103 utilizes existing conventional techniques. The rotation of the ball screw 103 drives the screw nut to move. The screw nut seat 104 has parallel limiting grooves 1041 on both sides. A swing rod 105 is installed within each limiting groove 1041. One end of the swing rod 105 is spherical and slides relative to the limiting groove 1041, while the other end is cylindrical. The sleeve 102 has through grooves 1021 on both sides, symmetrically arranged with respect to the screw nut, and adapted to the swing rod. The lower end of the ball screw 103 has a hexagonal rod 1031, adapted to the first connecting sleeve 414. Specifically, the through grooves 1021 and the swing rod 103... One end of the 05 is adapted, and the extension path of the balance rod 105 corresponds to the bracelet mounting position of the watch case. That is to say, the specifications and dimensions of the balance rod 105 correspond to the gaps in the bracelets of two adjacent watch cases. When the control ball screw 103 rotates, the screw nut seat 104 moves from bottom to top under its rotation. Restricted by the balance rod 105 within the limiting groove 1041, when the screw nut seat 104 moves, it pushes the balance rod 105 outward, thus acting between the bracelet mounting positions of two adjacent watch cases. One balance rod 105 on one side extends obliquely upward, and the other extends obliquely downward. In this way, the synchronous operation of each balance rod 105 is achieved. The material can be tilted synchronously so that it is arranged at an angle on the sleeve 102. This increases the gap between two adjacent workpieces and fully exposes the corners, providing convenient conditions for the subsequent grinding mechanism 9 to grind the workpiece and ensuring the quality of the processing. Furthermore, the spherical limiting groove 1041 near the end of the swing rod 105 has a circular cross-section to ensure the smoothness of the swing rod 105 under the drive of the screw nut seat 104. When the workpiece needs to be unloaded after grinding, the auxiliary drive mechanism 11 can cooperate with it to retract the position of the swing rod 105, providing convenience for the smooth unloading of the workpiece.
[0045] To facilitate the removal of workpieces from the clamping mechanism 7, an auxiliary drive mechanism 11 is provided below the clamping mechanism 7. The auxiliary drive mechanism 11 includes a longitudinal slide bar 111 positioned below the fixed plate 75. Below the slide bar 111 is a Z-shaped longitudinal transfer frame 112. A longitudinal drive cylinder 113 is located on the rear side of the fixed plate 75 and connected to the longitudinal transfer frame 112. A rotating rod 114 is positioned above the other side of the longitudinal transfer frame 112. A second connecting sleeve 115 is mounted on the rotating rod 114, and the second connecting sleeve 115 also has an internal hexagonal hole. A second driven gear 116 is positioned below the rotating rod 114, and a second driving gear 117 is positioned on one side of the second driven gear 116. Specifically, when the clamping mechanism... 7. After the polishing workpiece placed on the tilting mechanism 10 is completed, the longitudinal drive cylinder 113 is controlled to operate, driving the longitudinal transfer frame 112 to move closer to the bottom of the tilting mechanism 10, especially so that the second connecting sleeve 115 is close to the bottom of the tilting mechanism 10. Before the second connecting sleeve 115 moves to the appropriate position, the first finger cylinder 76 is released slightly, and the vertical drive cylinder 710 in the clamping mechanism 7 is controlled to operate, adjusting the position of the tilting mechanism 10, especially so that the hexagonal rod 1031 in the tilting mechanism 10 is away from the moving path of the second connecting sleeve 115. Of course, the clamping end of the first finger cylinder 76 is always close to the bottom of the tilting mechanism 10. After the second connecting sleeve 115 moves to the hexagonal rod After the vertical position of 1031 is reached, the vertical drive cylinder 710 is reversed and operated, causing the hexagonal rod 1031 to be inserted into the second connecting sleeve 115. Subsequently, the horizontal rodless drive cylinder 66 is operated to adjust the position of the end of the tilting mechanism 10 carrying the workpiece, bringing it closer to the external workpiece collection area. Then, the second drive gear 117 is controlled to rotate, acting on the second driven gear 116, causing the rotating rod 114 and the second connecting sleeve 115 to rotate. In particular, this resets the various swing rods in the tilting mechanism 10, allowing the workpiece to return to its normal placement state. Then, when one end of the top of the sleeve 102 approaches the external workpiece collection area, the second clamping cylinder is controlled to release, allowing the workpiece to be automatically and smoothly discharged vertically. The adjustment of the position of the tilting mechanism 10 is achieved by rotating the rotating frame 71. That is to say, during the grinding process, the tilting mechanism 10 and the workpiece are adjusted to be placed in a horizontal position. When the workpiece is unloaded, it can be tilted with one end of the second finger cylinder 79 pointing downwards, or it can be placed vertically downwards. Regardless of the position, the workpiece can be unloaded from the sleeve 102 by its own weight, which to a certain extent realizes the convenient unloading of the processed workpiece and meets the usage requirements. After the workpiece on the tilting mechanism 10 is completely unloaded, the rotating frame 71 adjusts its position to restore it to a vertical position and places it back into the material holding mechanism 3, waiting for the convenient placement of subsequent materials. It is highly practical.
[0046] To facilitate the convenient unloading of materials placed on the tilting mechanism 10, the top-loading mechanism 5 includes a vertical screw movement adjustment mechanism 51 installed in the worktable 1. The moving end of the vertical screw movement adjustment mechanism 51 is equipped with a moving frame 52, and a top rod 53 is installed on the moving frame 52. A through hole 21 is opened in the rotating disk 2 corresponding to the top rod 53, and it abuts against the ring plate 101. Specifically, after the material is assisted in clamping by the clamping mechanism 7 above the tilting mechanism 10, the loading mechanism 3 opens, creating a gap between the tilting mechanism 10 and the material for unloading. Subsequently... The tilting mechanism 10 tilts the workpiece on the sleeve 102, and then the vertical screw moving adjustment mechanism 51 is controlled to move, causing its moving end to rise and act on the push rod 53. The push rod 53 passes through the rotating disk 2 and contacts the bottom of the tilting mechanism 10. In particular, it can push the sleeve 102 out of the material holding mechanism 3, providing convenient conditions for the lower device of the clamping mechanism 7 to clamp the device. Of course, when the push rod 53 passes through the rotating disk 2, it can also stabilize its position and prevent it from shifting, ensuring the convenience of workpiece loading and unloading and meeting the usage requirements.
[0047] To improve the functionality of the device, the two-axis moving assembly 8 includes a longitudinal lead screw movement adjustment mechanism 81. A support frame 82 is provided at the moving end of this mechanism, and a transverse lead screw movement adjustment mechanism 83 is provided on the support frame 82. Specifically, the lead screw movement adjustment mechanism is a conventional technique that uses the rotation of a lead screw to move equipment components. The longitudinal lead screw movement adjustment mechanism 81 allows for convenient adjustment of the longitudinal position of the grinding mechanism 9, bringing the device closer to the workpiece. The transverse lead screw movement adjustment mechanism 83 allows for adjustment of the transverse position of the grinding mechanism 9, ensuring that the grinding mechanism 9's path fully covers the multiple workpieces placed on it, thus improving the work process to a certain extent.
[0048] To ensure smooth grinding operations and improve workflow, the grinding mechanism 9 includes a carrier 91 mounted above the two-axis moving assembly 8. A longitudinal slide block assembly 92 is mounted on the carrier 91. This assembly typically comprises slides and sliders arranged longitudinally on the carrier 91, ensuring smooth longitudinal movement of the adjusting frame 93. An L-shaped adjusting frame 93 is positioned above the longitudinal slide block assembly 92, and a longitudinal rack 94 is positioned below it. A transmission gear is located on one side of the longitudinal rack 94. The grinding mechanism 95 is equipped with a first grinding head 96, a second grinding head 97, and a third grinding head 98 arranged in a triangular shape on the short side of the adjusting frame 93. The first grinding head 96 and the second grinding head 97 are respectively located on the left and right sides of the corner of the adjusting frame 93, and the third grinding head 98 is located below. A transmission wheel 99 is provided on the inner and outer sides of each of the first grinding head 96, the second grinding head 97, and the third grinding head 98, and a transmission belt 910 is provided on the outer side of the transmission wheel 99. Specifically, the grinding mechanism 9 can be moved and adjusted horizontally and vertically under the drive of the two-axis moving assembly 8. The vertical adjustment... The section allows the grinding mechanism 9 to be closer to the workpiece, and the lateral adjustment makes the grinding work more thorough. To ensure the precision of the grinding work, the transmission gear 95 is controlled to rotate, and its rotation acts on the longitudinal rack 94. This causes the adjusting frame 93 to move relative to the carrier 91 along with the longitudinal rack 94 and under the limit of the longitudinal slide block assembly 92, so that the grinding mechanism 9 is moved closer to the workpiece, especially for grinding the front and rear corners of the workpiece, ensuring the comprehensiveness of the grinding work and improving the work process. As for the implementation of the grinding work: the section located on one side of the third grinding head 98... The transmission wheel 99 is the main drive wheel and receives the driving power from an externally installed motor. The rotation of the transmission wheel 99 acts on the transmission belt 910 to drive the grinding heads to rotate synchronously. Each grinding head generally includes a rotating shaft that runs through the adjusting frame 93 and a grinding wheel located at the outer end of the rotating shaft. According to the size of the workpiece to be processed, the gap between the first grinding head 96 and the second grinding head 97 and the third grinding head 98 is adjusted so that they can contact the outer end face of the workpiece. The rotation of the grinding heads can achieve polishing processing of the workpiece surface, which greatly improves the functionality of the device and meets the usage requirements.
