Description
Technical Field
[0001] This application relates to the technical field of watch repair, and particularly to a pointer disassembly machine for watch movements. Background Art
[0002] A watch is a precision product. When the inside of the watch is damaged, the watch is likely to have inaccurate timekeeping, and at this time, the watch needs to be disassembled for repair.
[0003] In the related art, when repairing a watch, a repairman needs to use tweezers, insert the pointed head of the tweezers into the gap between two pointers, and lift the tweezers upward to remove the pointer at the upper position from the fixed shaft of the watch.
[0004] Regarding the above related art, the inventor believes that a watch is a precision product, the gap between two pointers is small, and when the repairman inserts the tweezers into the gap between the two pointers, the hand is likely to shake, resulting in the tweezers colliding with the pointers; and the pointers are thin and light watch parts, which are easily deformed under the collision of the tweezers. Summary of the Invention
[0005] In order to reduce the situation where the pointer is damaged by collision during watch repair, this application provides a pointer disassembly machine for watch movements.
[0006] The pointer disassembly machine for watch movements provided by this application adopts the following technical solutions: 1. A pointer disassembly machine for watch movements, including a machine base, a support frame is arranged on the machine base; a measuring component and a disassembly component are arranged on the support frame; The measuring component includes a measuring rod and a measuring piece, and the measuring piece is connected to the lower end of the measuring rod; the upper end of the measuring rod passes through the support frame, and an adjusting component for driving the measuring rod to move downward is arranged on the top wall of the support frame; The disassembly component includes a disassembly rod and a disassembly fork, and the disassembly fork is connected to the lower end of the disassembly rod; the upper end of the disassembly rod passes through the support frame, an adjusting tube is rotatably connected to the top wall of the support frame, the disassembly rod passes through the adjusting tube and is threadedly connected to the adjusting tube, a limiting rod for limiting the disassembly rod is arranged on one side of the disassembly rod, and the limiting rod is telescopic; a driving component for driving the disassembly component to move is arranged on the support frame; A positioning piece for positioning the relative positions of the measuring rod and the disassembly rod is arranged on the disassembly component.
[0007] By adopting the above technical solution, when the watch needs to be repaired, first open the watch cover, then fix the watch on the base, start the adjusting component to drive the measuring rod to drive the measuring piece to move downward. When the measuring piece moves to the same height as the gap between two adjacent pointers, the measuring rod stops moving; turn the adjusting tube to drive the disassembly rod to drive the disassembly fork to move downward. The positioning piece can position the disassembly rod, so that the disassembly rod can only move downward to the position where the disassembly fork is at the same height as the measuring piece. Then use the driving component to drive the disassembly rod to drive the disassembly fork, so that the disassembly fork is inserted between two watch pointers, and then turn the adjusting tube to drive the disassembly rod to drive the disassembly fork to move upward, and the pointer can be removed from the fixed shaft.
[0008] The measuring component can position the position between two adjacent pointers before the pointer is disassembled; it can reduce the situation where the disassembly fork collides with the pointer when the disassembly component disassembles the pointer, thereby reducing the situation where the pointer is damaged by collision during the watch repair process.
[0009] Preferably, an adjusting sleeve is rotatably connected to the top wall of the support frame. The measuring rod is inserted into the adjusting sleeve and is threadedly connected to the adjusting sleeve. The limiting rod can limit the measuring rod. The adjusting component includes a knob, a main gear and a sub-gear. The knob is rotatably connected to the top wall of the support frame. The main gear is coaxially arranged with the knob, and the sub-gear is coaxially arranged with the adjusting sleeve; the main gear meshes with the sub-gear.
[0010] By adopting the above technical solution, turning the knob drives the main gear to drive the sub-gear to rotate, and the sub-gear drives the adjusting sleeve to rotate, so as to drive the measuring rod to move downward.
[0011] Preferably, the number of teeth of the main gear is less than the number of teeth of the sub-gear.
[0012] By adopting the above technical solution, the sub-gear can reduce the speed of the operator turning the knob, so that the rotation speed of the adjusting sleeve is low, so that the measuring rod drives the measuring piece to move downward more slowly, and the stability of the measuring piece positioning the pointer is improved.
[0013] Preferably, the positioning piece is a positioning rod. One end of the positioning rod is fixedly connected to the disassembly rod, and the other end of the positioning rod is in contact with the upper end of the measuring rod.
[0014] By adopting the above technical solution, when the measuring rod moves downward, it will be separated from the positioning rod by a certain distance; when the measuring rod stops moving and the disassembly rod moves downward, the disassembly rod will drive the positioning rod to move downward. When the positioning rod moves downward to be in contact with the upper end wall of the measuring rod, it can stop moving, so as to realize the positioning of the relative positions of the measuring rod and the disassembly rod.
[0015] Preferably, a guide rod is arranged at one end of the positioning rod close to the measuring rod. The guide rod is inserted into the measuring rod from the upper end of the measuring rod.
[0016] By adopting the above technical solution, with the guide rod inserted into the measuring rod, the measuring rod can limit the side wall of the guide rod, further limit the positioning rod, and reduce the situation that the excessive downward movement of the disassembly rod drives the positioning rod to bend.
[0017] Preferably, the positioning member is a telescopic rod. One end of the telescopic rod is rotatably connected to the upper end of the measuring rod, and the other end of the telescopic rod is rotatably connected to the upper end of the disassembly rod; a limiting block is arranged on the side wall of the measuring rod, and the limiting block can be attached to the side wall of the telescopic rod.
[0018] By adopting the above technical solution, when the measuring rod moves downward, it will drive the telescopic rod to rotate and extend, and the telescopic tube will be disengaged from the limiting block at the same time; after the measuring rod stops moving, the disassembly rod moves downward, further driving the telescopic rod to rotate and contract. After the telescopic rod rotates to be attached to the top wall of the limiting block, the disassembly rod stops moving, thereby realizing the positioning of the disassembly rod.
[0019] Preferably, the telescopic rod includes a sleeve and an extension tube. The sleeve is connected to the measuring rod, and the extension tube is connected to the disassembly rod; the limiting block can be attached to the outer side wall of the sleeve.
[0020] By adopting the above technical solution, the outer diameter of the sleeve is larger than that of the extension tube. The connection of the sleeve to the measuring rod can make the whole telescopic tube in a horizontal state when the limiting block contacts the side wall of the sleeve, reducing the positioning error of the telescopic tube for the measuring rod and the disassembly rod.
[0021] Preferably, the driving component includes a slider and a lead screw. A chute is opened on the support frame, and the slider is inserted into the chute and can slide along the length direction of the chute; the lead screw passes through the slider and is threadedly connected to the slider; the disassembly rod and the adjusting tube are connected to the slider.
[0022] By adopting the above technical solution, when the disassembly fork moves downward to be at the same height as the gap between two adjacent pointers, the lead screw can be rotated to drive the slider to move, and the movement of the slider drives the disassembly rod to move, so that the disassembly fork can be inserted between two watch pointers.
[0023] Preferably, the measuring member is a laser emitter, and the laser beam of the laser emitter is flush with the lower end of the disassembly rod.
[0024] Generally, the measuring member is a small-diameter needle-shaped or sheet-shaped object. The operator needs to observe the position of the measuring member and the pointer with the naked eye. Limited by the support frame, the observation angle of the operator is from top to bottom obliquely, resulting in easy observation errors; by adopting the above technical solution, the operator only needs to observe that the laser beam of the laser emitter is located between two adjacent pointers, and then stop the downward movement of the measuring rod, reducing the observation error.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The measuring component can position the position between two adjacent pointers before the pointer is disassembled; it can reduce the collision between the disassembly fork and the pointer when the disassembly component disassembles the pointer, thereby reducing the damage of the pointer caused by collision during the watch repair process.
[0026] 2. The setting of the main gear and the auxiliary gear can reduce the speed when the measuring rod moves downwards and improve the stability of the measuring piece for positioning the pointer.
[0027] 3. The setting of the laser emitter can reduce the observation error of the operator during measurement. Description of the Drawings

Detailed Description of the Embodiment
[0031] The following further Figure 1-2 describes the present application in detail.
[0032] The embodiment of the present application discloses a watch movement pointer disassembly machine.
[0033] Embodiment 1: Referring to Figure 1 , the watch movement pointer disassembly machine includes a machine base 1, and a support frame 11 is welded and connected to the top wall of the machine base 1; a measuring component 2 and a disassembly component 3 are installed on the support frame 11.
[0034] Referring to Figure 1 , the measuring component 2 includes a measuring rod 21 and a measuring piece 22. The measuring piece 22 is a laser emitter, and the measuring piece 22 is connected to the lower end of the measuring rod 21 by screws; the upper end of the measuring rod 21 passes through the support frame 11, and an adjusting sleeve 13 is rotatably provided on the top wall of the support frame 11. The measuring rod 21 passes through the adjusting sleeve 13 and is threadedly connected to the inner side wall of the adjusting sleeve 13; an adjusting component 4 is also provided on the top wall of the support frame 11.
[0035] Referring to Figure 1, the adjusting assembly 4 includes a knob 41, a main gear 42 and a secondary gear 43. The knob 41 is rotatably connected to the top wall of the support frame 11. The main gear 42 is welded to the outer side wall of the knob 41 and is coaxially arranged with the knob 41. The secondary gear 43 is welded to the outer side wall of the adjusting sleeve 13 and is coaxially arranged with the adjusting sleeve 13. The main gear 42 meshes with the secondary gear 43, and the number of teeth of the main gear 42 is less than that of the secondary gear 43.
[0036] Refer to Figure 1 , the disassembly assembly 3 includes a disassembly rod 31 and a disassembly fork 32. The disassembly fork 32 is welded to the lower end of the disassembly rod 31. The upper end of the disassembly rod 31 penetrates through the support frame 11. A driving assembly is further provided on the support frame 11 to drive the disassembly assembly 3 to move horizontally.
[0037] Refer to Figure 1 , the driving assembly includes a slider 16 and a lead screw 17. A chute 15 is opened on the top wall of the support frame 11. The slider 16 is inserted into the chute 15 and can slide along the length direction of the chute 15. An adjusting tube 12 is rotatably connected to the top wall of the slider 16. The disassembly rod 31 passes through the adjusting tube 12 and the slider 16 at the same time and is threadedly connected to the inner wall of the adjusting tube 12. The lead screw 17 penetrates through the slider 16 in the horizontal direction and is threadedly connected to the slider 16. One end of the lead screw 17 is rotatably connected to the inner side wall of the chute 15, and the other end of the lead screw 17 passes through the inner side wall of the chute 15 and simultaneously penetrates through the support frame 11 and extends out from the outer side wall of the support frame 11.
[0038] Refer to Figure 1 , a limiting rod 14 is screw - connected to the bottom wall of the support frame 11. The limiting rod 14 is telescopic, and both ends of the limiting rod 14 can be respectively inserted into the pre - opened chutes 15 on the side walls of the measuring rod 21 and the disassembly rod 31.
[0039] Refer to Figure 1 , a positioning member is connected to the disassembly assembly 3. The positioning member is a positioning rod 5. One end of the positioning rod 5 is screw - connected to the end wall of the disassembly rod 31, and the other end of the positioning rod 5 can be attached to the upper end of the measuring rod 21. A guide rod 51 is welded to one end of the positioning rod 5 close to the measuring rod 21. The guide rod 51 passes through the upper end wall of the measuring rod 21 and is inserted into the measuring rod 21.
[0040] Refer to Figure 1 , a clamping assembly is provided on the top wall of the machine base 1. When the watch needs to be repaired, first open the watch cover, and then clamp the watch into the clamping assembly. Start the measuring member 22 to emit laser. The operator rotates the knob 41 to drive the main gear 42 to drive the secondary gear 43 to rotate. The secondary gear 43 drives the adjusting sleeve 13 to rotate, thereby driving the measuring rod 21 to move downward. The measuring rod 21 can drive the measuring member 22 to move downward. After the laser beam on the measuring member 22 moves between the two watch hands, stop rotating the knob 41. During the downward movement of the measuring rod 21, the guide rod 51 is simultaneously driven to move out of the measuring rod 21.
[0041] Turn the adjustment tube 12 to drive the disassembly rod 31 and the disassembly fork 32 to move downward. The disassembly rod 31 simultaneously drives the positioning rod 5 to move downward, and the positioning rod 5 drives the guide rod 51 to move and insert into the measuring rod 21. After the positioning rod 5 moves downward until it abuts against the upper end wall of the measuring rod 21, the disassembly rod 31 stops moving. At this time, the gap between the disassembly fork 32 and the two watch hands is at the same height. Turn the screw rod 17 to drive the slider 16 to move. The slider 16 drives the disassembly rod 31 to move, so that the disassembly fork 32 is inserted between the two watch hands. Then turn the adjustment tube 12 to drive the disassembly rod 31 to drive the disassembly fork 32 to move upward, and the hands can be removed from the fixed shaft.
[0042] Embodiment 2 is different from Embodiment 1 in that: Refer to Figure 1 and Figure 2 , the positioning member is a telescopic rod 6. The telescopic rod 6 includes a sleeve 61 and an extension tube 62. The extension tube 62 is inserted into the sleeve 61. The sleeve 61 is rotatably connected to the upper end of the measuring rod 21, and the extension tube 62 is rotatably connected to the upper end of the disassembly rod 31. A limiting block 211 is welded to the outer side wall of the measuring rod 21.
[0043] When the measuring rod 21 moves downward, it drives the sleeve 61 and the extension tube 62 to rotate and tilt. As the measuring rod 21 moves downward, the extension tube 62 extends out of the sleeve 61, realizing the extension of the telescopic rod 6. After the measuring rod 21 stops moving, the disassembly rod 31 moves downward, further driving the telescopic rod 6 to rotate and contract. After the telescopic rod 6 rotates until the outer side wall of the sleeve 61 abuts against the top wall of the limiting block 211, the disassembly rod 31 stops moving, thereby realizing the positioning of the disassembly rod 31.
[0044] The implementation principle of the watch movement hand disassembly machine in the embodiment of the present application is as follows: When the watch needs to be repaired, first open the watch cover, and then clamp the watch into the clamping assembly. Start the measuring member 22 to emit laser. The operator turns the knob 41 to drive the main gear 42 to drive the secondary gear 43 to rotate. The secondary gear 43 drives the adjusting sleeve 13 to rotate, thereby driving the measuring rod 21 to move downward. The measuring rod 21 can drive the measuring member 22 to move downward. After the laser beam on the measuring member 22 moves between the two watch hands, stop turning the knob 41. During the downward movement of the measuring rod 21, the guide rod 51 is simultaneously moved out of the measuring rod 21.
[0045] Turn the adjusting tube 12 to drive the disassembly rod 31 and the disassembly fork 32 to move downward. The disassembly rod 31 simultaneously drives the positioning rod 5 to move downward, and the positioning rod 5 drives the guide rod 51 to move and insert into the measuring rod 21. After the positioning rod 5 moves downward until it abuts against the upper end wall of the measuring rod 21, the disassembly rod 31 stops moving. At this time, the disassembly fork 32 is located between the two watch hands. Turn the screw rod 17 to drive the slider 16 to move. The slider 16 drives the disassembly rod 31 to move, so that the disassembly fork 32 is inserted between the two watch hands. Then turn the adjusting tube 12 to drive the disassembly rod 31 to drive the disassembly fork 32 to move upward, and the hands can be removed from the fixed shaft.
[0046] The setting of the measuring assembly 2 can position the position between two adjacent hands before the hands are disassembled, and can reduce the situation that the disassembly fork 32 collides with the hands when the disassembly assembly 3 disassembles the hands, thereby reducing the situation that the hands are damaged by collision during the watch repair process.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
