DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 The present embodiment proposes a gear hobbing machine tool holder angle adjustment mechanism, including a base 1, the top of the base 1 is fixedly connected to the operating machine 2, the top of the base 1 is provided with an adjusting device 3, the adjusting device 3 includes a track plate 31, the bottom of the track plate 31 is fixedly connected to the top of the base 1, the top of the track plate 31 is slidably connected to a movable plate 32, the top of the movable plate 32 is fixedly connected to a rectangular rod 33, the end of the rectangular rod 33 away from the movable plate 32 is fixedly connected to a cross bar 34, the side of the cross bar 34 is fixedly connected to a motor 35, a gear 36 is fixedly connected to the output shaft of the motor 35, a thin rod 37 is fixedly connected to the side of the cross bar 34, the end of the thin rod 37 away from the cross bar 34 is slidably connected to a rack 38, the side of the rack 38 is fixedly connected to a connecting rod 310, the side of the rectangular rod 33 is fixedly connected to a movable seat 315, the top of the movable seat 315 is penetrated by an upper top 311, and the end of the connecting rod 310 away from the rack 38 is fixedly connected to the top of the upper top 311.

[0029] The rack 38 and the gear 36 are meshed with each other. A switch 313 is provided on the top of the motor 35. The connecting rod 310 is made of metal. The rack 38 and the gear 36 are meshed with each other. The rotation of the gear 36 drives the rack 38 to move up and down.

[0030] The side of the base 1 is rotatably connected to a cabinet door 7, and two cabinet doors 7 are provided. An adjusting rod 9 is provided on the side of the operating machine 2, and a pressure gauge 10 is provided on the side of the operating machine 2. The design of the pressure gauge 10 is conducive to observing the air pressure of the operating machine 2.

[0031] The side of the crossbar 34 is fixedly connected to a limit rod 312 , and one end of the limit rod 312 away from the crossbar 34 is slidably connected to the side of the rack 38 . The design of the limit rod 312 is conducive to limiting the movement trajectory of the rack 38 .

[0032] The bottom of the cross bar 34 is fixedly connected to a ruler 314, the rack 38 is located on the side of the ruler 314, the top of the movable plate 32 is fixedly connected to an eccentric top seat 5, and the top of the eccentric top seat 5 is rotatably connected to a rotating rod 6. The design of the ruler 314 is conducive to observing the height adjustment of the upper top 311.

[0033] In this embodiment, after the gear hobbing machine has been used for a period of time, a coaxial error will occur between the upper center 311 and the rotary table, resulting in reduced production accuracy. By adjusting the position of the upper center 311 of the gear hobbing machine, it can be accurately aligned with the rotary table, thereby significantly reducing the coaxial error. When the position of the upper center deviates, the machine is first stopped and the motor 35 is started. The forward rotation of the motor 35 drives the gear 36 to rotate forward, and the gear 36 and the rack 38 are engaged with each other. The forward rotation of the gear 36 drives the rack 38 to move upward on the thin rod 37. The upward displacement of the rack 38 drives the upper center to move upward. The reverse rotation of the motor 35 drives the upper center 311 to move downward. The position of the upper and lower displacements can be visually measured by the ruler 314. In this way, the position of the upper center 311 is adjusted. By adjusting the position of the upper center 311, the coaxial error can be significantly reduced, which means that during the gear hobbing process, the cutting trajectory of the tool will be more precise, which can ensure that the processed gears, racks and other workpieces meet the design requirements, improve the consistency and reliability of the product, and adopt the adjustment method of the motor 35 and the gear 36 to achieve more precise and convenient adjustment. This automated adjustment method reduces the labor intensity of the operator and reduces the errors caused by manual operation, making the adjustment process more efficient and reliable. The coaxial error will cause uneven wear of the tool, thereby accelerating the failure of the tool. By adjusting the upper center 311, the stability of the cutting process can be maintained.

[0034] Example 2

[0035] like Figures 3 to 5 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes another embodiment, a clamping and locking mechanism 4 is provided on the top of the base 1, and the clamping and locking mechanism 4 includes a vertical rod 41, one end of the vertical rod 41 is fixedly connected to the top of the base 1, and the side of the vertical rod 41 is rotatably connected to a bidirectional screw rod 42, a connecting belt 45 is fixedly sleeved on the output shaft of the motor 35, and the end of the connecting belt 45 away from the motor 35 is fixedly sleeved on the circumferential surface of the bidirectional screw rod 42, a threaded sleeve 43 is threadedly connected on the circumferential surface of the bidirectional screw rod 42, and a splint 46 is fixedly connected to the side of the threaded sleeve 43. The design of the splint 46 can lock the adjusted height of the upper top 311.

[0036] There are two threaded sleeves 43 and two clamping plates 46, which are symmetrical to each other along the vertical center axis of the bidirectional screw rod 42. An extrusion block is provided on the side of the operating machine 2, and the shape of the teeth on the gear hobbing is squeezed out by the extrusion block.

[0037] A round rod 44 is fixedly connected to the side of the vertical rod 41. The end of the round rod 44 away from the vertical rod 41 passes through the side of the threaded sleeve 43. The bidirectional screw rod 42 is set to be made of metal. The bidirectional screw rod 42 made of metal is harder, convenient for long-term use, and not easy to damage.

[0038] The bidirectional screw rod 42 is located above the extrusion block, the upper top 311 is located above the eccentric top seat 5, the vertical rod 41 is set to metal material, the upper top 311 is located on the displacement track of the splint 46, and the bidirectional screw rod 42 is located above the extrusion block, which does not affect the extrusion block's extrusion of the gear hobbing.

[0039] There are several buttons 8 arranged along a linear array on the side of the operating machine 2. A warning light is provided on the side of the operating machine 2. The side of the base 1 is fixedly connected with a shell 11. The design of the shell 11 is conducive to protecting the eccentric top seat 5 and also plays a role in covering up the ugliness.

[0040] In this embodiment, the forward rotation of the above-mentioned motor 35 will drive the connecting belt 45 to rotate forward, and the forward rotation of the connecting belt 45 will drive the bidirectional screw 42 to rotate forward. The forward rotation of the bidirectional screw 42 will drive the two threaded sleeves 43 to move relative to each other, and the relative movement of the two threaded sleeves 43 will drive the two clamps 46 to move relative to each other. The limiting rod 312 also passes through the side surfaces of the two threaded sleeves 43. The upper center 311 is located in the middle of the two clamps 46. The upper center 311 is located on the movement trajectory of the clamps 46. When the two clamps 46 move relative to each other, the two sides of the upper center 311 will be clamped and temporarily fixed and locked. During the operation of the gear hobbing machine, as the use time increases, coaxial errors may occur between the upper center 311 and the rotary worktable due to wear, thermal expansion or external force. By clamping the upper center 311 through the relative movement of the clamping plates 46, its position can be effectively adjusted, thereby improving the coaxiality and ensuring the processing accuracy. When the two clamping plates 46 clamp the upper center 311, a stable fixing effect can be provided to prevent the upper center from being displaced during the processing and keep it in the ideal working position. This stability is crucial for high-precision processing.
