Description

Technical Field

[0001] This utility model relates to the field of ratchet gear processing technology, and in particular to a ratchet gear processing fixture device for quick clamping. Background Technology

[0002] A ratchet is a mechanical transmission component with a special tooth profile. Its core feature is that the teeth are unidirectionally inclined ratchet-shaped, which enables unidirectional intermittent motion or prevents reverse rotation. A quick-clamping ratchet machining fixture is a special fixture used to improve the installation efficiency of ratchet assemblies. Its core function is to achieve rapid positioning and clamping of the ratchet through an adjustable design, ensuring accurate installation and improving product reliability.

[0003] In existing technologies, traditional devices require specific fixtures to hold the sea buckthorn raw material in place when fixing it. Since ratchet gears come in various specifications and the thickness of the central shaft varies significantly, if the fixture lacks an adjustable clamping mechanism, it cannot flexibly adapt to different sizes of central shafts, and can only process ratchet gears of specific sizes. This fails to meet the needs of small-batch, multi-variety customized production. In automated production lines, frequent fixture changes to accommodate different ratchet gear specifications significantly increase downtime and reduce production pace. A thin central shaft may deform due to excessive clamping force, while a thick central shaft may loosen due to insufficient clamping force, both leading to processing vibration or tooth profile errors. When the clearance between the fixture and the central shaft is too large, the ratchet gear is prone to slight displacement during processing, affecting tooth surface accuracy and consistency. Therefore, it is necessary to improve the ratchet gear processing fixture device with rapid clamping to solve these problems. Utility Model Content

[0004] To overcome the limitations of quick-clamping ratchet machining fixtures in holding diverse sea buckthorn wheels, which prevents them from meeting the demands of small-batch, multi-variety customized production, and to address issues such as machining vibration or tooth profile errors affecting tooth surface accuracy and consistency.

[0005] The technical solution of this utility model is as follows: a quick-clamping ratchet machining fixture device, including a machining device, a protective partition plate disposed on the top of the machining device, a claw disk body disposed on the machining device, a mounting connection seat fixedly connected to the machining device, a cooling device disposed on the machining device, a plug-in connection plate disposed on the machining device, a machining component disposed on the mounting connection seat, an adjusting rotating rod rotatably connected inside the claw disk body, a threaded rotating disk fixedly connected to the adjusting rotating rod, a threaded adjusting rod rotatably connected inside the threaded rotating disk, a sliding threaded block slidably connected inside the claw disk body, an anti-slip pad disposed on the sliding threaded block, the threaded adjusting rod engaging with the threaded rotating disk, and the sliding threaded block engaging with the threaded adjusting rod. The rotation of the adjusting rotating rod drives the threaded rotating disk to rotate inside the claw disk body, and the engagement of the threaded rotating disk with the threaded adjusting rod drives the rotation inside the claw disk body.

[0006] Preferably, the claw disc body has a groove at the corresponding position of the sliding threaded block, and the sliding threaded block slides inside the groove.

[0007] Preferably, four sliding threaded blocks are provided, and the four sliding threaded blocks are evenly slidably connected inside the claw disk body.

[0008] Preferably, the processing device is equipped with a first electric telescopic rod, a sliding connecting seat is fixedly connected to the first electric telescopic rod, the sliding connecting seat is slidably connected inside the processing device, a support mounting seat is fixedly connected to the sliding connecting seat, a connecting support plate is fixedly connected to the processing device, a first motor is fixedly connected to one side of the connecting support plate, a rotating rod is fixedly connected to the output of the first motor, the claw disc body is fixedly connected to the rotating rod, a second motor is fixedly connected inside the claw disc body, and the output end of the second motor is fixedly connected to the adjusting rotating rod.

[0009] Preferably, the processing device has a groove at the corresponding position of the sliding connecting seat, and the sliding connecting seat slides inside the groove.

[0010] Preferably, the processing component includes a third motor fixedly connected to the mounting bracket, a rotating threaded rod fixedly connected to the output end of the third motor, a sliding threaded support seat threadedly connected to the rotating threaded rod, a sliding support plate slidably connected inside the sliding threaded support seat, a second electric telescopic rod disposed between the sliding threaded support seat and the sliding support plate, a connecting mounting bracket fixedly connected to the sliding support plate, a ratchet processing shaft rotatably connected inside the connecting mounting bracket, and a fixed connecting rod fixedly connected inside the mounting bracket. The sliding threaded support seat is slidably connected to the fixed connecting rod, and the sliding support plate is slidably connected inside the sliding threaded support seat.

[0011] Preferably, the mounting connector has a groove at the corresponding position of the sliding threaded support, and the sliding threaded support slides inside the groove.

[0012] Preferably, the sliding threaded support seat has a groove at the corresponding position of the sliding support plate, and the sliding support plate slides inside the groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. Compared to ratchet machining fixtures that cannot quickly clamp diverse sea buckthorn wheels, this device uses an adjustable rotating rod to drive a threaded rotating disk. The threaded adjusting rod, in conjunction with the threaded rotating disk, rotates within the claw disk body. The threaded adjusting rod, in conjunction with a sliding threaded block, causes the anti-slip pad on the sliding threaded block to fix the ratchet. This eliminates the need for specific fixtures to secure the sea buckthorn material, allows for flexible adaptation to different sized shafts, and meets the needs of small-batch, multi-variety customized production. It reduces downtime, accelerates production, prevents machining vibration or tooth profile errors, and ensures tooth surface accuracy and consistency.

[0015] 2. The sliding support plate is pulled by the second electric telescopic rod and slides inside the sliding threaded support seat. The sliding of the sliding threaded support seat drives the ratchet machining shaft on the connecting mounting seat to process the ratchet. The screw rotation drives the clamp or tool to move. Utilizing the self-locking characteristic of the threaded transmission, a stable force output can be maintained during clamping or cutting, reducing vibration. For example, when cutting water pipes, the screw rotation causes the clamping plate to move synchronously, ensuring that the pipe is accurately pushed to the cutting position, and the clamping force is stable during the cutting process, avoiding tooth shape errors caused by vibration. Relying on the telescopic movement of hydraulic or pneumatic cylinders, if the seals are worn or the pressure fluctuates, the clamping force may be unstable, especially during high-speed cutting, which can easily cause vibration and affect the tooth surface quality.

The upper sliding threaded block 811 is engaged with the threaded adjusting rod 810. The rotation of the adjusting rotating rod 808 drives the threaded rotating disk 809 to rotate inside the claw disk body 3. Under the condition that the threaded rotating disk 809 is engaged with the threaded adjusting rod 810, the claw disk body 3 rotates, inserting the central shaft on the ratchet gear into the inner side of the anti-slip pad 812. The rotation of the adjusting rotating rod 808 drives the threaded rotating disk 809 to rotate inside the claw disk body 3. Under the condition that the threaded rotating disk 809 is engaged with the threaded adjusting rod 810, the threaded adjusting rod 810 rotates inside the claw disk body 3. Under the condition that the threaded adjusting rod 810 is engaged with the sliding threaded block 811, the sliding threaded block 811 slides. The sliding of the sliding threaded block 811 causes the anti-slip pad 812 to clamp and fix the central shaft of the ratchet gear.

[0024] Please see Figure 2 - Figure 3 In this embodiment, the claw disc body 3 has a groove at the corresponding position of the sliding threaded block 811. The sliding threaded block 811 slides inside the groove. The groove at the corresponding position of the sliding threaded block 811 inside the claw disc body 3 makes the sliding threaded block 811 more stable when sliding inside the groove. Four sliding threaded blocks 811 are provided, and the four sliding threaded blocks 811 are evenly slidably connected inside the claw disc body 3. The four sliding threaded blocks 811 provide greater stability when clamping the ratchet gear. The processing device 1 is provided with a first electric telescopic rod 801. A sliding connecting seat 802 is fixedly connected to the first electric telescopic rod 801. The sliding connecting seat 802 is slidably connected inside the processing device 1.

The claw plate body 3 is fixedly connected to the rotating rod 806. A second motor 807 is fixedly connected inside the claw plate body 3. The output of the second motor 807 is fixedly connected to an adjusting rotating rod 808. The first motor 805 drives the rotating rod 806 to rotate inside the connecting support plate 804. The rotation of the rotating rod 806 drives the claw plate body 3 to rotate. The rotation of the claw plate body 3 drives the ratchet gear to rotate. The processing device 1 has a groove at the corresponding position of the sliding connecting seat 802. The sliding connecting seat 802 slides inside the groove. The groove at the corresponding position of the sliding connecting seat 802 inside the processing device 1 limits the sliding connecting seat 802 when it slides inside the groove.

[0025] Please see Figure 4 - Figure 5In this embodiment, the processing component includes a third motor 901 fixedly connected to the mounting base 4, a rotating threaded rod 902 fixedly connected to the output end of the third motor 901, a sliding threaded support 903 threadedly connected to the rotating threaded rod 902, a sliding support plate 905 slidably connected inside the sliding threaded support 903, a second electric telescopic rod 906 disposed between the sliding threaded support 903 and the sliding support plate 905, a connecting mounting base 907 fixedly connected to the sliding support plate 905, a ratchet processing shaft 908 rotatably connected inside the connecting mounting base 907, and a fixed connecting rod 909 fixedly connected inside the mounting base 4. The sliding threaded support 903 is slidably connected to the fixed connecting rod 909, and the sliding support plate 905 is slidably connected inside the sliding threaded support 903. The third motor 901 drives the rotating threaded rod 902 to rotate inside the mounting base 4, and under the condition that the rotating threaded rod 902 is threadedly connected to the sliding threaded support 903, the sliding threaded support 903 is driven to rotate. The mounting connector 4 slides to a suitable position inside, and the second electric telescopic rod 906 pulls the sliding support plate 905 to slide inside the sliding threaded support 903, moving the connecting mounting seat 907 on the ratchet processing shaft 908 to a suitable height. The motor inside the connecting mounting seat 907 drives the ratchet processing shaft 908 to rotate, thus improving the ratchet processing effect. The mounting connector 4 has a groove corresponding to the sliding threaded support 903, and the sliding threaded support 903 slides inside the groove. The groove inside the mounting connector 4 corresponding to the sliding threaded support 903 makes the sliding threaded support 903 more stable when sliding inside the groove. The sliding threaded support 903 has a groove corresponding to the sliding support plate 905, and the sliding support plate 905 slides inside the groove. The groove inside the sliding threaded support 903 corresponding to the sliding support plate 905 limits the sliding threaded support 903 when sliding inside the groove.

[0026] During operation, the central shaft of the ratchet is inserted into the inner side of the anti-slip pad 812. The second motor 807 drives the adjusting rotating rod 808 to rotate inside the claw plate body 3. The rotation of the adjusting rotating rod 808 causes the threaded rotating disk 809 to rotate inside the claw plate body 3. With the threaded rotating disk 809 engaged with the threaded adjusting rod 810, the threaded adjusting rod 810 rotates inside the claw plate body 3. With the threaded adjusting rod 810 engaged with the sliding threaded block 811, the sliding threaded block 811 slides. The sliding of the sliding threaded block 811 causes the anti-slip pad 812 to clamp and fix the central shaft of the ratchet. The first electric telescopic rod 801 pushes the sliding connecting seat 802, causing the support mounting seat 803 to move inside the processing device 1. The movement of the support mounting seat 803 causes the insertion connecting plate 6 to contact and fix the ratchet. The third motor 901... The drive screw rod 902 rotates inside the mounting connector 4. With the screw rod 902 threadedly connected to the sliding screw support 903, the sliding screw support 903 slides to a suitable position inside the mounting connector 4. The second electric telescopic rod 906 pulls the sliding support plate 905 to slide inside the sliding screw support 903, moving the connecting mounting seat 907 on the ratchet processing shaft 908 to a suitable height. The motor inside the connecting mounting seat 907 drives the ratchet processing shaft 908 to rotate, thus improving the ratchet processing effect. During ratchet processing, the first motor 805 drives the rotating rod 806 to rotate inside the connecting support plate 804. The rotation of the rotating rod 806 drives the pawl body 3 to rotate, which in turn drives the ratchet to rotate, ensuring the stability of ratchet processing.

[0027] Through the above steps, the rotating rod 808 drives the threaded rotating disk 809 to rotate. With the cooperation of the threaded adjusting rod 810 and the threaded rotating disk 809, the threaded adjusting rod 810 rotates inside the claw disk body 3. With the cooperation of the threaded adjusting rod 810 and the sliding threaded block 811, the anti-slip pad 812 on the sliding threaded block 811 is fixed to the ratchet. This solves the problem that the quick-clamping ratchet processing fixture device cannot clamp diverse sea buckthorn wheels, which makes it unable to meet the customized production needs of small batches and multiple varieties, and the problems of processing vibration or tooth profile error affecting the accuracy and consistency of the tooth surface.
