Description

Technical Field

[0001] This utility model relates to a shaft production and processing equipment, specifically a cutting device for the production and processing of watch movement shafts. Background Technology

[0002] The watch crown is the shaft that connects the crown to the watch movement. The function of the crown is to transmit the power of the fingers turning it to the movement, thereby completing a series of actions such as winding the mainspring, adjusting the time, and setting the date.

[0003] During the production and processing of shafts, the raw material needs to be cut to the appropriate length to ensure that the length and diameter of the shaft meet the design requirements. Since the raw material of shafts is generally stainless steel or a special alloy, a cutting device is needed to facilitate the cutting process.

[0004] The current cutting device is inconvenient for moving the shaft material. Since the shaft material needs to be cut in multiple segments, it needs to be moved and cut again after one end is cut. Therefore, if the shaft material is long, it is difficult and inconvenient to move it manually. Utility Model Content

[0005] The main objective of this disclosure is to provide a cutting device for manufacturing and processing watch movement shafts, so as to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cutting device for manufacturing and processing watch movement shafts includes a worktable. An internal groove is formed near the left side of the worktable. A translation screw is rotatably mounted in the internal groove, and two sliding rods are fixedly mounted therein. A translation plate is threaded onto the translation screw and slidably connected to the two sliding rods. An arc-shaped groove is formed at the upper end of the translation plate, and a fixing block is provided at the upper end. A rocker wheel is rotatably mounted on the left side of the worktable and is fixedly connected to the rotating shaft of the translation screw. Clamping blocks are movable near both the front and rear sides of the upper end of the worktable. A fixed frame is fixedly installed near the right side of the upper end of the workbench. A lifting plate is provided inside the fixed frame, and a cutting motor is fixedly installed inside the lifting plate. A cutting disc is rotatably installed on the left side. The output end of the cutting motor is fixedly connected to the cutting disc. The shaft material is fixed on the translation plate. By rotating the translation screw by the first rocker wheel, the translation plate can slide on the two slide rods, thereby driving the shaft material for cutting. Then, the shaft material can be fixed by the two clamping blocks, so that the cutting disc can be rotated by the cutting motor for cutting.

[0008] Preferably, a U-shaped plate is fixedly installed at the upper end of the sliding plate, and a fixing screw is threadedly installed on the U-shaped plate. The fixing screw passes through the U-shaped plate. A fixing block is rotatably installed at the lower end of the fixing screw, and a vertical rod is fixedly installed at the upper end of the fixing block. The vertical rod passes through the U-shaped plate and is slidably connected to the U-shaped plate. A knob is fixedly installed at the upper end of the fixing screw. By turning the fixing screw, the fixing block can be lowered. At the same time, the vertical rod will slide on the U-shaped plate to make the fixing block rise and fall smoothly. When the fixing block is lowered and comes into contact with the shaft material, the shaft material can be fixed on the sliding plate for easy movement and use.

[0009] Preferably, a second built-in groove is provided near the center of the workbench, and a bidirectional screw is rotatably installed in the second built-in groove. Slide plates are threaded onto the threads on both sides of the bidirectional screw. Openings are provided near the front and rear sides of the upper end of the workbench. Two slide plates extend to the upper end of the workbench through the two openings respectively. Two clamping blocks are fixedly installed on the two slide plates by connecting rods respectively. A flat support plate is provided between the two clamping blocks. A second rocker wheel is rotatably installed on the front side of the workbench. The second rocker wheel is fixedly connected to the rotating shaft of the bidirectional screw. By rotating the bidirectional screw through the second rocker wheel, the two slide plates can be moved towards each other, thereby moving the two clamping blocks towards each other through the connecting rod. This allows for clamping, fixing, or disassembling of the shaft material for use.

[0010] Preferably, a built-in groove three is provided near the right side of the workbench, and a translation screw two is rotatably installed in the built-in groove three. An L-shaped connecting plate is threaded onto the translation screw two. An opening is provided near the right side of the upper end of the workbench, and the L-shaped connecting plate extends to the upper end of the workbench through the opening. A stop plate is fixedly installed on the left side of the L-shaped connecting plate. A rocker wheel three is rotatably installed on the right side of the workbench. The rocker wheel three is fixedly connected to the rotating shaft of the translation screw two. By rotating the translation screw two through the rocker wheel three, the L-shaped connecting plate can be moved horizontally on the upper end of the workbench with the stop plate. The stop plate is adjusted to the appropriate length according to the required cutting length of the shaft material. Then, the shaft material is moved directly so that one end contacts the stop plate, which can limit the cutting and facilitate the use.

[0011] Preferably, a lifting screw is rotatably installed on the front inner side of the fixed frame, and a limiting rod is fixedly installed on the rear inner side. The lifting plate is T-shaped, and openings are opened on both the front and rear inner sides of the fixed frame. One side of the lifting plate is threaded onto the lifting screw, and the other side is slidably installed onto the limiting rod. By rotating the lifting screw, the lifting plate slides on the limiting rod, thereby allowing the cutting disc to be raised and lowered for cutting.

[0012] Preferably, a servo motor is fixedly installed on the upper end of the mounting bracket, and the output end of the servo motor is fixedly connected to the lifting screw shaft. The servo motor controls the forward and reverse rotation of the lifting screw for use.

[0013] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, by setting a translation plate, when the shaft material needs to be moved during cutting, the shaft material is fixed on the translation plate by fixing blocks. Then, by rotating the translation screw by the rocker wheel, the translation plate can slide on the two slide rods, thereby driving the shaft material to move for use, which is more labor-saving and convenient.

[0022] Please see Figure 1-5 The present invention provides the following embodiments:

[0023] A cutting device for manufacturing and processing watch movement shafts includes a worktable 1. An internal groove 2 is formed near the left side of the worktable 1. A translation screw 3 is rotatably installed in the internal groove 2, and two sliding rods 4 are fixedly installed therein. A translation plate 5 is threaded onto the translation screw 3 and slidably connected to the two sliding rods 4. An arc-shaped groove is formed at the upper end of the translation plate 5, and a fixing block 9 is provided at the upper end. A rocker wheel 6 is rotatably installed on the left side of the worktable 1 and is fixedly connected to the rotating shaft of the translation screw 3. A clamping block 16 is movable near both the front and rear sides of the upper end of the worktable 1. A fixed mounting bracket 24 is installed on the right side. A lifting plate 27 is provided inside the fixed bracket 24 and can be raised and lowered. A cutting motor 30 is fixedly installed inside the lifting plate 27, and a cutting disc 29 is rotatably installed on the left side. The output end of the cutting motor 30 is fixedly connected to the cutting disc 29. The shaft material is fixed on the translation plate 5. By rotating the translation screw 3 through the rocker wheel 6, the translation plate 5 can slide on the two slide rods 4, thereby driving the shaft material for cutting. Then, the shaft material can be fixed by the two clamping blocks 16, so that the cutting disc 29 can be rotated by the cutting motor 30 for cutting.

[0024] Specifically, a U-shaped plate 7 is fixedly installed on the upper end of the translation plate 5. A fixing screw 8 is threaded onto the U-shaped plate 7 and passes through the U-shaped plate 7. A fixing block 9 is rotatably installed on the lower end of the fixing screw 8, and a vertical rod 10 is fixedly installed on the upper end of the fixing block 9. The vertical rod 10 passes through the U-shaped plate 7 and is slidably connected to the U-shaped plate 7. A knob 11 is fixedly installed on the upper end of the fixing screw 8. By rotating the fixing screw 8 with the knob 11, the fixing block 9 can be lowered. At the same time, the vertical rod 10 will slide on the U-shaped plate 7 to make the fixing block 9 rise and fall smoothly. When the fixing block 9 is lowered and comes into contact with the shaft material, the shaft material can be fixed on the translation plate 5 for easy movement and use.

[0025] Specifically, a second built-in groove 12 is opened near the center of the workbench 1. A bidirectional screw 13 is rotatably installed in the second built-in groove 12. Slide plates 14 are threaded on both sides of the bidirectional screw 13. Openings are opened near the front and rear sides of the upper end of the workbench 1. The two slide plates 14 extend to the upper end of the workbench 1 through the two openings respectively. Two clamping blocks 16 are fixedly installed on the two slide plates 14 through the connecting rods 15 respectively. A flat support plate 18 is provided between the two clamping blocks 16. A second rocker wheel 17 is rotatably installed on the front side of the workbench 1. The second rocker wheel 17 is fixedly connected to the rotating shaft of the bidirectional screw 13. By rotating the bidirectional screw 13 through the second rocker wheel 17, the two slide plates 14 can be moved towards each other. Thus, the two clamping blocks 16 can be moved towards each other through the connecting rods 15. The shaft material can be clamped, fixed or disassembled for use.

[0026] Specifically, a built-in groove 3 19 is provided near the right side of the workbench 1. A translation screw 20 is rotatably installed in the built-in groove 3 19. An L-shaped connecting plate 21 is threaded onto the translation screw 20. An opening is provided near the right side of the upper end of the workbench 1. The L-shaped connecting plate 21 extends to the upper end of the workbench 1 through the opening. A stop plate 22 is fixedly installed on the left side of the L-shaped connecting plate 21. A rocker wheel 3 23 is rotatably installed on the right side of the workbench 1. The rocker wheel 3 23 is fixedly connected to the rotating shaft of the translation screw 20. By rotating the translation screw 20 through the rocker wheel 3 23, the L-shaped connecting plate 21 can be moved horizontally on the upper end of the workbench 1 with the stop plate 22. The stop plate 22 is adjusted to the appropriate length according to the required cutting length of the shaft material. Then, the shaft material is moved directly so that one end contacts the stop plate 22, which can limit the cutting and facilitate the use.

[0027] Specifically, a lifting screw 25 is rotatably installed on the front inner side of the fixed frame 24, and a limiting rod 26 is fixedly installed on the rear inner side. The lifting plate 27 is T-shaped, and openings are opened on both the front and rear inner sides of the fixed frame 24. One side of the lifting plate 27 is threaded onto the lifting screw 25, and the other side is slidably installed onto the limiting rod 26. By rotating the lifting screw 25, the lifting plate 27 slides on the limiting rod 26, thereby allowing the cutting disc 29 to be raised and lowered for cutting.

[0028] Specifically, a servo motor 28 is fixedly installed on the upper end of the mounting bracket 24. The output end of the servo motor 28 is fixedly connected to the rotating shaft of the lifting screw 25. The servo motor 28 is used to control the forward and reverse rotation of the lifting screw 25.

[0029] The working principle of this utility model is as follows: First, the shaft material is placed on the upper end of the translation plate 5 and the flat support plate 18. Then, according to the required cutting length of the shaft, the translation screw 20 is rotated by the rocker wheel 3 23 to make the L-shaped connecting plate 21 move along with the abutment plate 22 on the worktable 1. After the abutment plate 22 is moved to the appropriate position, one end of the shaft material is brought into contact with the abutment plate 22. Then, the bidirectional screw 13 is rotated by the rocker wheel 2 17 to move the two sliding plates 14 closer to each other. This is achieved by the connecting rod 15, which brings the two clamping blocks 16 closer to each other and brings them into contact with the shaft material, fixing them in the front-to-back direction. Then, the fixing screw 8 is rotated by the knob 11 to lower the fixing block 9, while the vertical rod 10 slides on the U-shaped plate 7 to make it stable. The material is lowered so that the fixing block 9 is lowered to contact the shaft material for vertical fixation. After fixation, the cutting motor 30 is turned on to drive the cutting disc 29 to rotate. At the same time, the servo motor 28 drives the lifting screw 25 to rotate, so that the lifting plate 27 slides on the limit rod 26. The lifting plate 27 lowers with the rotating cutting disc 29 to cut the shaft material. After cutting a section, the two-way screw 13 is reversed again by the rocker wheel 2 17, so that the two clamping blocks 16 move away from each other and away from the shaft material to release the front and back fixation. At this time, the translation screw 3 is rotated by the rocker wheel 1 6, so that the translation plate 5 slides on the two slide rods 4, thereby moving the shaft material to the right to cut the next section.
