Description

Technical Field

[0001] The present invention relates to the technical field of gear shaper tool setting, and particularly to a cutting machine tool for automatic tool setting type gear processing. Background Art

[0002] The workpiece blank is correctly clamped on the workbench of the gear shaper to ensure firm clamping and that the positioning reference is consistent with the machine tool coordinate system, such as positioning through a mandrel, a three-jaw chuck, etc. Install the gear shaper cutter, check whether the cutter model, number of teeth, and module match the processing requirements, and calibrate the radial runout and end face runout of the cutter with a dial indicator, usually controlled within 0.01 - 0.02 mm. Even for a new gear shaper cutter, there may be installation errors during installation, such as radial runout and axial runout of the cutter. These errors will cause tooth profile errors, tooth direction errors, etc. in the processed gears. To eliminate the influence of installation errors, it is necessary to remove the gear shaper cutter, reinstall and calibrate it to ensure that the tool installation accuracy meets the requirements.

[0003] In the process of connecting the existing gear shaper cutter to the connecting shaft, threads are used to connect and fix the cutter inside the working shaft. When the above calibration requires the gear shaper cutter to be disassembled, this will consume a lot of time during the calibration process, prolong the calibration time, and lead to a decline in the production process.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of cutting machine technology for automatic cutter-setting gear processing, by setting a non-disassembly angle adjustment design, has completely changed the cumbersome process of disassembling parts when calibrating the traditional gear cutter. When the gear cutter needs to be calibrated, there is no need to spend a lot of time disassembling related components as in the past. Just follow the operation in step 2, press the rotary handle to release the limit and turn it to drive the parts to rotate, and the angle of the bottom gear cutter can be adjusted. This greatly shortens the time required for the calibration process, avoids the time waste caused by disassembly, effectively improves the calibration efficiency, and lays the foundation for the efficient implementation of the production process.

[0016] 2. The cutting machine tool technology for automatic tool setting type gear processing fundamentally solves the pain point of traditional calibration that requires removing the cutting tool by adopting a quick clamping method in the device. When the sleeve tool holder is sleeved on the bottom of the connecting shaft, after the rotating rod fits against the side of the connecting shaft, quick clamping is achieved through the reset push of rod A, without cumbersome operations such as bolt fastening. When it is necessary to calibrate the angle of the cutting tool, only need to press the rotating handle to release the limit, and through the linkage of gear meshing and the clamping structure, the cutting tool can be driven to complete the angle adjustment. This clamping method eliminates the disassembly link in the calibration process, shortens the originally time-consuming process caused by disassembly to a minute-level operation, and avoids the decline of the production process due to calibration interruption.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The top of the tooth cutter 4 is movably connected to a sleeve handle 5, and a quick connector 6 is arranged on the side of the sleeve handle 5. The sleeve handle 5 is clamped inside the connecting shaft 3 through the quick connector 6. During the operation process, the internal structure of the sleeve handle 5 and the connecting shaft 3 is quickly clamped to complete the assembly; when it is necessary to adjust the angle of the tooth cutter 4, rotating the quick connector 6 can drive the tooth cutter 4 to perform precise fine-tuning. This design does not require manual disassembly of components, simplifies the operation steps, significantly improves the work efficiency, and optimizes the overall work process.

[0021] Please refer to Figure 4 and Figure 5, the interior of the sleeve shank 5 includes a movable cavity 51, a limiting cylinder 52, a limiting transverse plate 53, a built-in sleeve 54, an arc slope 55 and a guiding groove 56. A movable cavity 51 is provided inside the sleeve shank 5, and the built-in sleeve 54 is movably sleeved inside the movable cavity 51. The bottom of the built-in sleeve 54 is fixedly welded to the top of the tooth cutter 4 through a connecting rod passing through the bottom of the sleeve shank 5. A limiting cylinder 52 is fixedly installed inside the built-in sleeve 54, and a limiting transverse plate 53 is arranged at the top of the limiting cylinder 52. Guiding grooves 56 are provided at the top of the built-in sleeve 54 and inside the sleeve shank 5, and they are interconnected. The connection of the two ends of the guiding groove 56 is set as an arc slope 55. The interior of the sleeve shank 5 further includes a rod B58, a piston sleeve plate 57, a telescopic rod 510, a spring E512, a limiting plug plate 513, an expansion head 514 and a built-in cross groove 515. A rod B58 is fixedly installed inside the limiting cylinder 52. A spring D59 is movably sleeved on the outer wall of the rod B58. A piston sleeve plate 57 is movably sleeved on the top of the rod B58. A telescopic rod 510 is fixedly installed on the top of the piston sleeve plate 57. A limiting transverse plate 53 is fixedly installed on the top of the telescopic rod 510. Limiting cavities are provided on both sides of the limiting transverse plate 53. Side rods 511 are fixedly installed inside the limiting cavities. A spring E512 is movably sleeved on the outer wall of the side rod 511. The side of the spring E512 is in contact connection with the limiting plug plate 513. The interior of the limiting plug plate 513 and the outer wall of the side rod 511 are movably sleeved, and an expansion head 514 is fixedly installed on the side of the limiting plug plate 513 away from the spring E512. A built-in cross groove 515 is provided in the middle of the limiting transverse plate 53, The inside of the sleeve tool holder 5 is provided with an activity cavity 51. The built-in sleeve 54 is movably sleeved in the activity cavity 51 and is fixedly connected to the toothed cutter 4 through a connecting rod. The activity cavity 51 is sleeved at the bottom of the connecting shaft 3, and the bottom of the connecting shaft 3 can be inlaid and installed in the built-in cross groove 515 inside the limit cross plate 53; when the sleeve tool holder 5 moves to a suitable position to be clamped with the connecting shaft 3, the bottom of the connecting shaft 3 generates a thrust on the limit cross plate 53, so that the limit cross plate 53 slides into the built-in sleeve 54 along the guiding groove 56 to release the limit. Furthermore, the rotation of the bottom of the connecting shaft 3 can drive the limit cross plate 53, the limit cylinder 52 and the toothed cutter 4 to rotate to achieve angle adjustment; when the limit cross plate 53 moves downward, the telescopic rod 510 at its bottom pushes the piston sleeve plate 57 to extrude the spring D59 along the outer wall of the rod B58 to store energy. At the same time, the built-in sleeves 54 on both sides of the limit cross plate 53 slide from the guiding groove 56 in the activity cavity 51 into the guiding groove 56 in the built-in sleeve 54, prompting the expansion head 514 to push the limit plug plate 513 to contract into the limit cross plate 53 to release the limit, and the limit plug plate 513 and the expansion head 514 contract and extrude the spring E512 on the outer wall of the side rod 511 to store energy; when the bottom of the connecting shaft 3 disengages from the built-in cross groove 515, the spring D59 resets to push up the piston sleeve plate 57, and the piston sleeve plate 57 pushes the telescopic rod 510 and the limit cross plate 53 to slide back into the guiding groove 56 in the activity cavity 51. The spring E512 resets to push the limit plug plate 513 and the expansion head 514 out to be limited in the activity cavity 51. At this time, the toothed cutter 4 can only rotate with the sleeve tool holder 5. It should be noted that two symmetric long grooves are opened inside the piston sleeve plate 57 and the telescopic rod 510 and are adapted and limited by the limit pins fixedly connected to the top of the rod B58 to prevent the toothed cutter 4 from rotating by itself.

[0022] Please refer to Figure 4 , Figure 6 , Figure 9, the interior of the quick connector 6 includes a rotary handle 61, a sleeve 62, a rod A63, a spring A64, a movable plug 65, a rotary rod 66, and a driving block 67. The side of the sleeve handle 5 is fixedly connected to the sleeve 62. The rotary handle 61 is provided on the side of the sleeve 62. The rod A63 is movably sleeved inside the sleeve 62. The spring A64 is wound around the outer wall of the rod A63. The side of the spring A64 abuts against the movable plug 65. The interior of the movable plug 65 and the outer wall of the rod A63 are movably sleeved. A rotary rod 66 is fixedly installed on the outer wall of the movable plug 65 away from the spring A64. Driving blocks 67 are fixedly installed at both ends of the rotary rod 66. The ends of the rotary rod 66 and the driving block 67 away from the rotary handle 61 are both located inside the movable cavity 51. And the end of the rod A63 away from the driving block 67 is fixedly connected to the rotary handle 61. The interior of the quick connector 6 further includes a spring B641 and a limit block 631. A limit groove is opened inside one end of the sleeve 62 close to the rotary handle 61. The limit block 631 is clamped inside the limit groove. The bottom of the limit block 631 is fixedly connected to the outer wall of the rod A63. The spring B641 is movably sleeved around the outer wall of the rod A63 on the side of the rod A63 close to the rotary handle 61. An inner cavity 671 is opened inside the limit block 631. A limit ring 68 is fixedly installed inside the inner cavity 671. A connecting shaft rod 610 is fixedly installed on the top of the limit ring 68. A spring C69 is movably sleeved around the outer wall of the connecting shaft rod 610. The top of the connecting shaft rod 610 and the interior of the abutting block 611 are movably sleeved. When the sleeve handle 5 is connected to the bottom of the connecting shaft 3, the rotating rod 66 located inside the movable cavity 51 will fit with the side of the connecting shaft 3. When fitting, the space becomes smaller, which causes the rotating rod 66 to shrink toward the inside of the sleeve 62. During the shrinkage, the movable plug 65 fixed to the outer wall will be driven to squeeze the spring A64 along the outer wall of the rod A63. When the rotating rod 66 moves to the appropriate position, the limit is cancelled, which causes the rod A63 to reset. At that time, the sleeve 62 and the rotating rod 66 will be pushed to the inside of the connecting shaft 3, allowing the sleeve handle 5 to be quickly clamped to the bottom of the connecting shaft 3. When the toothed knife 4 at the bottom needs to be adjusted, the rotating handle can be 61 is pressed toward one side of the sleeve 62, which can squeeze the spring B641. At the same time, the limit block 631 stuck in the limit groove can extend into the interior of the sleeve 62. At this time, the limit is cancelled, and only the thumb of the cylinder needs to be turned to rotate the rotating handle 61 to drive the rod A63 to rotate, thereby driving the connected active plug 65 and the rotating rod 66 to rotate, and the angle of the toothed knife 4 connected at the bottom can be adjusted, avoiding the need for manual disassembly in the adjustment position, which can improve the overall work efficiency. When the adjustment is completed, the pressing of the rotating handle 61 can be cancelled, which causes the spring B641 to reset. When resetting, the rotating handle 61 will be pushed back to its original position, and the rod A fixedly connected to the rotating handle 61 63 will also be pulled to its original position, and the limit block 631 fixedly connected to the outer wall will be snapped into place with the inside of the limit groove, and the side slope of the block 611 movably sleeved on the top of the limit block 631 can quickly fit the block 611 with the inside of the limit groove. During the fitting process, the block 611 will move downward along the outer wall of the connecting shaft 610 to squeeze the spring C69. At that time, the friction between the block 611 and the inside of the limit groove will increase due to the rebound of the spring C69, so that the rod A63 will rotate during the working process to play a role of limiting. It should be noted that the rod A63 extends into the interior of the rotating rod 66 and the movable plug 65 and is fixed with a lateral limit The movable plug 65 and the rotating rod 66 are provided with a positioning pin, and connecting cavities are provided on both sides of the movable plug 65 and the rotating rod 66. The interior of the connecting cavity is engaged with the lateral limiting pin, and this engagement can play a limiting role, so that the rotating rod 66 can be driven to rotate when the rod A63 rotates. It should also be explained that the movable plug 65 has a mounting opening on the side facing the rod A63, and this mounting opening can only be movably connected with the outer wall of the rod A63, and the limiting pin installed on the rod A63 can only be limited in the interior of the connecting cavity. When disassembly is required, the outer wall of the rotating handle 61 can be held and pulled outward, so that the rod A63 can drive the rotating rod 66 to retract, which is convenient for disengagement and subsequent disassembly, thereby improving the use efficiency.

[0023] See also Figure 7 and Figure 8, the interior of the connecting shaft 3 includes a threaded port 31, a nut 32, a socket 33, a top block 34, a clamping shaft 35, a clamping port 36, a driving rod 37 and a cross clamping block 38. Four symmetric threaded ports 31 are provided on the bottom circumference of the connecting shaft 3. The interior of the threaded port 31 communicates with the socket 33. A top block 34 is adaptively installed inside the socket 33. The top block 34 is fixed by the nut 32 and the internal thread of the connecting shaft 3. The bottom of the top block 34 is fixedly installed with a clamping shaft 35. A clamping port 36 is provided on the side of the clamping shaft 35. The driving rod 37 is movably sleeved inside the clamping shaft 35. Cross clamping blocks 38 are fixedly installed at the top and bottom of the driving rod 37. The cross clamping blocks 38 and the built-in cross groove 515 are adapted to each other. The interior of the connecting shaft 3 further includes a rotating rod B311, a mounting plate B312, a socket plate 315, a mounting plate A371 and a rotating rod A381. The mounting plate B312 is fixedly installed inside the clamping shaft 35. The top of the mounting plate B312 is movably connected to the rotating rod B311. A bevel gear B310 is fixedly installed at the top of the rotating rod B311. The side of the bevel gear B310 is meshed with a bevel gear A39. The side of the bevel gear A39 is fixedly connected to the rotating rod A381. The outer wall of the rotating rod A381 is movably connected to the mounting plate A371. The top of the mounting plate A371 is fixedly connected to the top of the inner cavity of the clamping shaft 35. During the sleeving process of the sleeve tool holder 5 and the connecting shaft 3, the rotating rod 66 can extend into the clamping shaft 35 through the clamping port 36, thereby realizing clamping. When the rotating rod 66 extends into the clamping port 36, the driving clamping block 67 fixedly connected to its outer wall will sequentially pass through the inside of the mounting plate A371 and the rotating rod A381 to complete clamping; at the same time, the cross clamping block 38 at the bottom of the driving rod 37 forms a clamping connection with the inside of the built-in cross groove 515. When the sleeve tool holder 5 moves upward to cause the clamping port 36 to be sleeved with the rotating rod 66, the entire driving rod 37 will also move upward accordingly. After the clamping port 36 and the rotating rod 66 are sleeved, the top of the driving rod 37 will pass through the inside of the mounting plate B312 and the rotating rod B311 to form a clamping connection. At this time, by rotating the rotating rod 66, the bevel gear A39 can be driven to rotate; when the bevel gear A39 rotates, the meshed bevel gear B310 will also rotate accordingly; and the rotation of the bevel gear B310 can drive the driving rod 37 clamped to the rotating rod B311 at the bottom to rotate, finally realizing the angle adjustment of the bottom cutter 4. In this way, the adjustment action can be completed without disassembling the components. When it is necessary to disassemble the clamping shaft 35, the nut 32 can be rotated out of the threaded port 31. At this time, the connection with the top block 34 is cancelled, and such a limit disappears, so that the clamping shaft 35 can be quickly taken out, facilitating subsequent replacement and use.

[0024] Please refer to Figure 8The interior of the rotating rod A381 is provided with a groove A that is adapted to the top of the driving rod 37, and the interior of the rotating rod A381 is provided with a groove B that is adapted to the outer wall of the rotating rod 66. A circular opening is provided in the interior of the mounting plate A371 and the mounting plate B312 away from the rotating rod B311 and the rotating rod A381, and a connecting port is provided in the interior of the socket plate 315. The diameter of the cross block 38 fixedly connected to the top of the driving rod 37 is twice the inner diameter of the connecting port. The cross block 38 fixedly installed on the top of the driving rod 37 can be extended into the interior through the adapted groove A to form a card connection, and the driving block 67 fixedly installed on the side of the rotating rod 66 can be extended into through the groove B to form a card connection, which is convenient for subsequent rotation and adjustment, thereby improving work efficiency. By setting the circular opening, the driving rod 37 can be conveniently extended into the interior of the rotating rod B311 to form a card connection, and the circular opening can facilitate the free up and down movement of the driving rod 37, thereby improving work efficiency.

[0025] Working principle: When in use, Step 1: Component connection and initial limit The sleeve handle 5 has a movable cavity 51 formed inside, and the built-in sleeve 54 is movably sleeved in the movable cavity 51 and fixedly connected to the toothed cutter 4 via a connecting rod. The movable cavity 51 is sleeved with the bottom of the connecting shaft 3, and the bottom of the connecting shaft 3 is embedded in the built-in cross groove 515 inside the limiting horizontal plate 53. At this time, the telescopic rod 510 at the bottom of the limiting horizontal plate 53 cooperates with the piston sleeve 57, and the built-in sleeves 54, limiting plug plates 513, and expansion heads 514 on both sides of the limiting horizontal plate 53 form a limit, so that the toothed cutter 4 can only rotate with the sleeve handle 5; at the same time, during the sleeve connection of the sleeve handle 5 and the connecting shaft 3, the rotating rod 66 fits against the side of the connecting shaft 3 and retracts, driving the movable plug 65 to compress the spring A64. When the sleeve handle 5 is in the proper position, the rod A63 resets and pushes the sleeve 62 and the rotating rod 66 into the interior of the connecting shaft 3, realizing a quick engagement between the sleeve handle 5 and the bottom of the connecting shaft 3.

[0026] Step 2: Angle adjustment operation Pressing the rotating handle 61 squeezes the spring B641, and the limit block 631 engaged in the limit groove extends into the inside of the sleeve 62 to release the limit. Turning the rotating handle 61 drives the rod A63 to rotate, and then drives the movable plug 65 and the rotating rod 66 to rotate; the rotating rod 66 extends into the card interface 36, and the driving card block 67 on its outer wall passes through the mounting plate A371 and is engaged with the rotating rod A381, and the cross card block 38 at the bottom of the driving rod 37 is engaged with the built-in cross groove 515; the sleeve shank 5 moves upward to make the card interface 36 engage with the rotating rod 66, and the driving rod 37 moves upward accordingly, and the top passes through the mounting plate B312 and is engaged with the rotating rod B311; the rotation of the rotating rod 66 drives the bevel gear A39 to rotate, the bevel gear A39 drives the bevel gear B310 to rotate, and the bevel gear B310 drives the driving rod 37 to rotate, finally realizing the angle adjustment of the bottom tooth knife 4.

[0027] Step 3: Adjustment, reset and limitation Release the pressure on the rotary handle 61. The spring B641 resets and pushes the rotary handle 61 and the rod A63 back to their original positions. The limiting block 631 is engaged with the limiting groove, and the slope on the side of the abutting block 611 fits with the limiting groove, squeezing the spring C69 to increase the friction force and restricting the rotation of the rod A63. When disassembling, pull the rotary handle 61 to drive the rod A63 and the rotary rod 66 to contract, facilitating detachment.

[0028] Through the socketing, engagement, sliding and limiting structure cooperation between components, the device realizes non-detachable angle adjustment. First, the initial socketing and limitation of each component are completed to ensure a stable basic connection.
