Description

Technical Field

[0001] This utility model relates to the field of watch case processing technology, and more specifically, to a positioning component for watch case processing. Background Art

[0002] Watches are one of the most common accessories used to tell time in people's daily lives; watch cases are devices used to protect the internal parts of the watch; during the production and processing of watch cases, positioning components are used to fix them in place to prevent them from moving.

[0003] For example, CN216748449U discloses a positioning fixture for processing smartwatch cases. The key technical points of this fixture are: a worktable; a fixed base fixedly connected to the top of the worktable, with symmetrically arranged limit grooves at both ends; two clamping blocks slidably connected to the limit grooves; and a limiting mechanism located outside the fixed base and extending into the limit groove, fixedly connected to one end of each clamping block. This limiting mechanism is used to limit and fix the clamping blocks slidably connected within the limit groove, thereby ensuring that the two clamping blocks... The clamping blocks position and hold the workpiece to be processed. This is mainly achieved through a limiting mechanism. By placing the material to be processed between two clamping blocks, the clamping blocks move along the inner wall groove of the fixed base under external force. At this time, the clamping blocks drive the movable rod to move and apply pressure from the first spring. Simultaneously, the slot on the outer wall of the movable rod applies a pushing force to one end of the positioning plate, causing the positioning plate to move under the action of external force and the inclined plane until it contacts another slot on the outer wall of the movable rod. This prevents the movable rods from getting too close to each other and the clamping blocks from moving away from each other, achieving the purpose of quickly clamping and fixing the material and facilitating its removal.

[0004] The aforementioned positioning component for watch case processing also has certain shortcomings: since the positioning component does not have a rotation adjustment function, once it is necessary to change the processing direction of the watch case, the repeated disassembly and assembly of the watch case will increase the working time and thus reduce the working efficiency of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning component for watch case processing to solve the problems existing in the prior art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a positioning component for watch case processing, including a processing base, two positioning component bodies are detachably installed symmetrically along the center on the upper surface of the processing base, a direction rotation component is fixedly connected to the bottom end of the processing base, and a lubrication component is fixedly connected to one side of the upper surface of the direction rotation component.

[0007] The positioning component body includes a stabilizing block, a limiting rod, a limiting plate, and a first hydraulic telescopic rod. The limiting rod is fixedly connected to the top of the inside of the stabilizing block. Two limiting plates are symmetrically and movably sleeved on the surface of the limiting rod along the center. The first hydraulic telescopic rod is detachably installed at the bottom of the side wall of the limiting plate.

[0008] The limiting plate is fixedly connected to an L-shaped positioning plate at its top, and the side wall of the L-shaped positioning plate is bonded with an anti-slip pad. One end of the first hydraulic telescopic rod is connected to one side inside the stabilizing block.

[0009] The directional rotation assembly includes a stabilizing seat, a first bearing, and a connecting shaft. The first bearing is embedded in the middle of the upper surface of the stabilizing seat, and the connecting shaft is fixedly sleeved inside the first bearing.

[0010] The connecting shaft has a spur gear fixedly sleeved in the middle, a support plate is fixedly connected to one side of the upper surface of the stabilizer, a second hydraulic telescopic rod is detachably installed at the top of the side wall of the support plate, a gear rack is fixedly connected to one end of the second hydraulic telescopic rod, the side wall of the gear rack meshes with the side wall of the spur gear, and four grooves are formed in a rectangular array on the upper surface of the stabilizer.

[0011] The top of the stabilizing base is connected to a protective shell via a groove. The bottom of the protective shell is fixedly connected to four connecting rods in a rectangular array. A second bearing is embedded in the middle of the upper surface of the protective shell. The surface of the connecting rod is adapted to the inside of the groove. The top of the connecting shaft is connected to the lower surface of the processing base via the second bearing.

[0012] The lubrication assembly includes a first connecting plate, a second connecting plate, and a container. The top of the side wall of the first connecting plate is fixedly connected to the second connecting plate, and the bottom of the side wall of the first connecting plate is connected to the middle of the back of the protective shell.

[0013] The lower surface of the second connecting plate is detachably equipped with a hydraulic lifting rod, the bottom end of which is fixedly connected to an extrusion plate. The bottom end of the holding cylinder is connected to a connecting pipe. The surface of the extrusion plate is adapted to the interior of the holding cylinder. The interior of the holding cylinder is filled with lubricating oil. The bottom end of the connecting pipe is located directly above the meshing point of the spur gear and the gear rack.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. In the above solution, the positioning component is equipped with a direction rotation component. When it is necessary to change the processing direction of the watch case, the second hydraulic telescopic rod inside the direction rotation component is activated, which drives the gear rack to move. Because the side wall of the gear rack meshes with the side wall of the spur gear, and the spur gear is fixedly sleeved on the surface of the connecting shaft through the first bearing and the second bearing, the movement of the gear rack can drive the connecting shaft to rotate. Since the watch case is connected to the connecting shaft through the positioning component body and the processing seat, the rotation of the connecting shaft can change the processing direction of the watch case. Since the second hydraulic telescopic rod has an automatic extension and retraction function, it can save the time required for work, thereby improving the working efficiency of the device.

[0016] 2. In the above solution, the positioning component is equipped with a lubrication component. When the friction at the meshing point of the spur gear and the gear rack increases, the hydraulic lifting rod inside the lubrication component is activated, causing it to move the extrusion plate downwards. As the extrusion plate moves, it can squeeze the lubricating oil stored inside the holding cylinder into the inside of the connecting pipe, and then the connecting pipe drips the lubricating oil onto the meshing point of the spur gear and the gear rack, thereby reducing the friction between the two and improving the service life of the component.

One end of the first hydraulic telescopic rod 24 is connected to one side of the inside of the stabilizing block 21. The directional rotation assembly 3 includes a stabilizing seat 31, a first bearing 32, and a connecting shaft 33. The first bearing 32 is embedded in the middle of the upper surface of the stabilizing seat 31. The connecting shaft 33 is fixedly sleeved inside the first bearing 32. A spur gear 34 is fixedly sleeved in the middle of the surface of the connecting shaft 33. A support plate 35 is fixedly connected to one side of the upper surface of the stabilizing seat 31. A second hydraulic telescopic rod 36 is detachably installed at the top of the side wall of the support plate 35. A gear rack 37 is fixedly connected to one end of the second hydraulic telescopic rod 36. The side wall of the gear rack 37 meshes with the side wall of the spur gear 34. Four grooves are formed in a rectangular array on the upper surface of the stabilizing seat 31. A protective shell 38 is connected to the top of the stabilizing seat 31 through the grooves. The bottom end is fixedly connected to four connecting rods 39 in a rectangular array. A second bearing 30 is inlaid in the middle of the upper surface of the protective shell 38.

[0029] Benefits: The positioning component body 2 helps to fix the watch case and avoids displacement during processing.

[0030] The working process of this utility model is as follows:

[0031] In order to improve the working efficiency of the device, the positioning component is equipped with a direction rotation component 3. When it is necessary to change the processing direction of the watch case, the second hydraulic telescopic rod 36 inside the direction rotation component 3 is activated, which drives the gear rack 37 to move. Because the side wall of the gear rack 37 meshes with the side wall of the spur gear 34, and the spur gear 34 is fixedly sleeved on the surface of the connecting shaft 33 through the first bearing 32 and the second bearing 30, the movement of the gear rack 37 can drive the connecting shaft 33 to rotate. Since the watch case is connected to the connecting shaft 33 through the positioning component body 2 and the processing seat 1, the rotation of the connecting shaft 33 can change the processing direction of the watch case. Since the second hydraulic telescopic rod 36 has an automatic extension and retraction function, it can save the time required for work, thereby improving the working efficiency of the device.

[0032] In the above scheme, in order to improve the service life of the directional rotation component 3, a lubrication component 4 is provided when the positioning component is working. When the friction at the meshing point of the spur gear 34 and the gear rack 37 increases, the hydraulic lifting rod 43 inside the lubrication component 4 is activated, which drives the extrusion plate 44 to move downward. As the extrusion plate 44 moves, it can squeeze the lubricating oil stored inside the holding cylinder 45 into the inside of the connecting pipe 46, and then the connecting pipe 46 drips the lubricating oil onto the meshing point of the spur gear 34 and the gear rack 37, thereby reducing the friction between the two and improving the service life of the component.
