Abstract
Description
Technical Field
[0001] This utility model relates to the field of watch case processing technology, specifically a watch case positioning fixture. Background Technology
[0002] Watch case positioning fixtures are devices used to fix and position watch cases for subsequent processing or inspection. Below are some common watch case positioning fixtures and their characteristics: Polygonal internal hole watch case positioning fixture: A related patent of Han's Laser Technology Industry Group Co., Ltd. This fixture includes a platform, a first positioning element, a second positioning element, a third positioning element, a fourth positioning element, and a drive assembly. The platform is used to place the watch case. Each of the four positioning elements has a positioning surface. The drive assembly can drive the positioning elements closer to or further away from the watch case, so that the positioning surface fits or separates from the corresponding inner surface of the polygonal internal hole, thereby achieving precise positioning of watch cases with polygonal internal holes. It is suitable for processing scenarios such as laser marking.
[0003] The patent publication number "CN216748449U" discloses "This utility model applies to the field of positioning fixture technology, and provides a positioning fixture for processing smart watch cases, including: a worktable; a fixed base, which is fixedly connected to the top of the worktable, and the fixed base has symmetrically opened limit grooves at both ends; two clamping blocks, which are slidably connected in the limit grooves; and a limiting mechanism. This utility model, by setting a limiting mechanism, places the material to be processed between the two clamping blocks, causing the clamping blocks to move along the inner wall groove of the fixed base under the action of external force. At this time, the clamping blocks will drive the movable rod to move and apply pressure from the first spring. At the same time, the slot on the outer wall of the movable rod will apply a pushing force to one end of the positioning insert plate, causing the positioning insert plate to move under the action of external force and inclined plane until it contacts the other slot on the outer wall of the movable rod, making it difficult for the movable rods to get close to each other, and the clamping blocks no longer to move away from each other, thus achieving the purpose of quickly clamping and fixing the material."
[0004] In the aforementioned patent, the existing positioning fixture does not have a good flipping function, which makes it difficult to process the back of the watch case. It also does not have a good function to improve stability, and any shaking during the processing will affect the processing effect.
[0005] To address these issues, this invention provides a watch case positioning fixture. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a watch case positioning fixture, which solves the problem that the existing positioning fixtures do not have a good flipping function, making it very troublesome to process the back of the watch case.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a watch case positioning fixture, comprising a worktable, a flipping assembly fixedly mounted on the top of the worktable, clamping assemblies threadedly connected to both sides of the flipping assembly, and a stabilizing assembly fixedly mounted on the inner bottom wall of the worktable; the flipping assembly comprises a stabilizing frame and a rotating shaft, the stabilizing frame fixedly mounted on the top of the worktable, the rotating shaft connected to the inner side wall of the stabilizing frame via a bearing, a flipping frame fixedly connected to one end of the rotating shaft, a worm gear fixedly connected to the side wall of the rotating shaft, a connecting frame fixedly mounted on one side of the stabilizing frame, a motor fixedly mounted on one side of the connecting frame, a worm fixedly connected to the output end of the motor, and the worm gear meshing with the worm wheel.
[0008] Furthermore, the stabilizing component includes a second motor and a second threaded rod. The second motor is fixedly installed on the inner bottom wall of the workbench. The second threaded rod is fixedly connected to the output end of the second motor. A lifting plate is threadedly connected to the side wall of the second threaded rod. A locking rod is fixedly connected to the top of the lifting plate. Locking blocks are fixedly installed at the four corners of the tilting frame. The locking rod and the locking blocks are locked together.
[0009] By adopting the above technical solution, the shaking of the tilting frame can be stably limited, ensuring processing accuracy.
[0010] Furthermore, the stabilizing component also includes a stabilizing rod, which is fixedly installed on the inner bottom wall of the worktable, and the lifting plate is slidably connected to the stabilizing rod.
[0011] The above technical solution enhances the stability of the lifting platform and prevents it from shifting.
[0012] Furthermore, the number of stabilizer bars is two, and the two stabilizer bars are arranged opposite to each other.
[0013] The above technical solution ensures stability on both sides and smoother lifting.
[0014] Furthermore, the worktable is rectangular in shape, and its edges are rounded.
[0015] The above technical solution is practical, safe, and collision-resistant.
[0016] Furthermore, the clamping assembly includes a threaded rod and a clamping plate. The threaded rod is threadedly connected to both sides of the flipping frame, and the clamping plate is connected to one end of the threaded rod via a bearing. The clamping plate and the flipping frame are slidably connected.
[0017] The above technical solution allows for flexible clamping and adaptability to watch cases of different sizes.
[0018] Furthermore, the clamping assembly also includes a knob, which is fixedly connected to one end of the clamping plate.
[0019] The above technical solution is easy to operate and saves clamping time.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.
[0032] Reference Figures 1 to 4 This application provides a watch case positioning fixture, including a worktable 1. A flipping component 2 is fixedly installed on the top of the worktable 1. Clamping components 3 are respectively threaded to both sides of the flipping component 2. A stabilizing component 4 is fixedly installed on the inner bottom wall of the worktable 1. The flipping component 2 includes a stabilizing frame 21 and a rotating shaft 22. The stabilizing frame 21 is fixedly installed on the top of the worktable 1. The rotating shaft 22 is connected to the inner side wall of the stabilizing frame 21 through a bearing. A flipping frame 23 is fixedly connected to one end of the rotating shaft 22. A worm gear 24 is fixedly connected to the side wall of the rotating shaft 22. A connecting frame 25 is fixedly installed on one side of the stabilizing frame 21. A motor 26 is fixedly installed on one side of the connecting frame 25. A worm 27 is fixedly connected to the output end of the motor 26. The worm 27 and the worm gear 24 are meshed together. The worktable 1 is rectangular in shape, and the edges of the worktable 1 are rounded.
[0033] In this embodiment, the motor 26 is started, and the worm 27 fixedly connected to its output end will rotate accordingly. Since the worm 27 and the worm wheel 24 are meshed, the rotation of the worm 27 will drive the worm wheel 24 to rotate. The worm wheel 24 is fixedly connected to the side wall of the rotating shaft 22, so the rotating shaft 22 will also rotate. The rotating shaft 22 is connected to the inner side wall of the stabilizer 21 through a bearing, and one end of it is fixedly connected to the flipping frame 23. In this way, the rotation of the rotating shaft 22 will drive the flipping frame 23 to achieve a flipping action. The flipping frame 23 provides a flippable platform for the subsequent placement and fixing of the watch case, so that the watch case can be easily flipped so that both sides of the watch case can be in a suitable processing position to ensure that both sides can obtain a good processing effect. In this case, the lead angle of the worm wheel 24 and the worm 27 is less than the equivalent friction angle.
[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the stabilizing component 4 includes a second motor 41 and a second threaded rod 42. The second motor 41 is fixedly installed on the inner bottom wall of the workbench 1. The second threaded rod 42 is fixedly connected to the output end of the second motor 41. A lifting plate 43 is threadedly connected to the side wall of the second threaded rod 42. A locking rod 44 is fixedly connected to the top of the lifting plate 43. Locking blocks 45 are fixedly installed at the four corners of the tilting frame 23. The locking rod 44 and the locking blocks 45 are locked together. The stabilizing component 4 also includes a stabilizing rod 46. The stabilizing rod 46 is fixedly installed on the inner bottom wall of the workbench 1. The lifting plate 43 and the stabilizing rod 46 are slidably connected. There are two stabilizing rods 46, and the two stabilizing rods 46 are arranged opposite each other.
[0035] In this embodiment, the second motor 41 is started, which drives the threaded rod 42, which is fixedly connected to its output end, to start rotating. Since the lifting plate 43 is threadedly connected to the side wall of the threaded rod 42, the lifting plate 43 will move up and down along its axial direction when the threaded rod 42 rotates. At the same time, the lifting plate 43 is slidably connected to the stabilizing rod 46 fixedly installed on the inner bottom wall of the worktable 1, and there are two stabilizing rods 46 arranged opposite to each other. This ensures that the lifting plate 43 is more stable during the lifting process. The locking rod 44 fixedly connected to the top of the lifting plate 43 will engage with the locking blocks 45 fixedly installed at the four corners of the tilting frame 23 as the lifting plate 43 rises and falls. When the locking rod 44 and the locking block 45 engage, unnecessary shaking of the tilting frame 23 can be restricted, making the entire processing process more stable and avoiding the impact of shaking on the processing effect, thus ensuring processing accuracy and quality. In this case, the thread helix angle is less than the equivalent friction angle.
[0036] Reference Figures 1 to 4In one aspect of this embodiment, the clamping assembly 3 includes a threaded rod 31 and a clamping plate 32. The threaded rod 31 is threadedly connected to both sides of the flipping frame 23, and the clamping plate 32 is connected to one end of the threaded rod 31 by a bearing. The clamping plate 32 is slidably connected to the flipping frame 23. The clamping assembly 3 also includes a knob 33, which is fixedly connected to one end of the clamping plate 32.
[0037] In this embodiment, rotating the knob 33 drives the threaded rod 31 to rotate. Since the threaded rod 31 is threadedly connected to the flip frame 23, and the clamping plate 32 is connected to one end of the threaded rod 31 through a bearing and slidably connected to the flip frame 23, when the threaded rod 31 rotates, the clamping plate 32 will slide along the flip frame 23 to achieve the clamping or releasing action of the watch case.
[0038] Working principle: Rotating the knob 33 drives the threaded rod 31 to rotate. Since the threaded rod 31 is threadedly connected to the flip frame 23, and the clamping plate 32 is connected to one end of the threaded rod 31 through a bearing and slidably connected to the flip frame 23, when the threaded rod 31 rotates, the clamping plate 32 will slide along the flip frame 23 to achieve the clamping or releasing action of the watch case. Start the motor 26. The motor 26 starts to run, and the worm 27 fixedly connected to its output end will rotate accordingly. Since the worm 27 and the worm wheel 24 are meshed, the rotation of the worm 27 will drive the worm wheel 24 to rotate. Since the worm wheel 24 is fixedly connected to the side wall of the rotating shaft 22, the rotating shaft 22 will also rotate together. The rotating shaft 22 is connected to the inner wall of the stabilizer 21 via a bearing, and one end of it is fixedly connected to the flipping frame 23. In this way, the rotation of the rotating shaft 22 will drive the flipping frame 23 to achieve a flipping action. The flipping frame 23 provides a flippable platform for the subsequent placement and fixing of the watch case, so that the watch case can be easily flipped so that both sides of the watch case can be in a suitable processing position to ensure that both sides can obtain a good processing effect. In this case, the lead angle of the worm gear 24 and the worm 27 is less than the equivalent friction angle.
[0039] Motor 41 is started, which drives the threaded rod 42, which is fixedly connected to its output end, to start rotating. Since the lifting plate 43 is threadedly connected to the side wall of the threaded rod 42, the lifting plate 43 will move up and down along its axis when the threaded rod 42 rotates. At the same time, the lifting plate 43 is slidably connected to the stabilizing rod 46, which is fixedly installed on the inner bottom wall of the worktable 1. There are two stabilizing rods 46, which are arranged opposite to each other. This ensures that the lifting plate 43 is more stable during the lifting process. The locking rod 44 fixedly connected to the top of the lifting plate 43 will engage with the locking blocks 45 fixedly installed at the four corners of the tilting frame 23 as the lifting plate 43 rises and falls. When the locking rod 44 and the locking block 45 engage, unnecessary shaking of the tilting frame 23 can be limited, making the entire processing process more stable and avoiding the impact of shaking on the processing effect, thus ensuring processing accuracy and quality. In this case, the thread helix angle is less than the equivalent friction angle.
