Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a tooling for grooving automotive drive shafts. Background Technology

[0002] The driveshaft is a high-speed, low-support rotating body, so its dynamic balance is crucial. Generally, driveshafts undergo dynamic balancing tests and adjustments on a balancing machine before leaving the factory. For front-engine, rear-wheel-drive vehicles, it is the shaft that transmits the rotation of the transmission to the final drive. It can consist of several sections, which can be connected by universal joints. The driveshaft is an important component in the automotive transmission system for transmitting power. Its function is to work with the gearbox and drive axle to transmit the engine's power to the wheels, enabling the vehicle to generate driving force. Special-purpose vehicle driveshafts are mainly used in tank trucks, refueling trucks, water trucks, sewage suction trucks, septic tank trucks, fire trucks, high-pressure cleaning trucks, road clearing trucks, aerial work platforms, garbage trucks, and other vehicle types.

[0003] Existing drive shaft grooving fixtures, such as the one described in application number CN202320534610.4 (belonging to the field of cutting device technology), specifically an automotive drive shaft grooving fixture, address the problem of collecting the metal wires generated during cutting. The proposed solution includes a worktable, a clamping and rotating module, and a shaft. The top end of the worktable is fixedly connected to the clamping and rotating module, and the shaft is fixedly engaged inside the clamping and rotating module.

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-6 As shown, this embodiment proposes a grooving fixture for automotive drive shafts, including a distance adjustment cleaning component 1 and a grooving mechanism 4. A bolt-assembled clamping and rotating assembly 2 is provided above one end of the distance adjustment cleaning component 1, and a fixedly installed braking component 3 is provided on the outer periphery of the distance adjustment cleaning component 1. A bolt-assembled grooving mechanism 4 is provided at the top of the clamping and rotating assembly 2.

[0023] The grooving mechanism 4 includes a top base 401, a duct block 402, a gearbox 403, an output motor 404, a meshing gear set 405, a lead screw set 406, a sliding base 407, a second hydraulic cylinder 408, a lifting base 409, a servo motor 4010, and a milling cutter head 4011. The top base 401 is located at the top of the clamping rotating assembly 2, and the duct block 402 is provided on the top side of the top base 401. The gearbox 403 is provided at the outer end of the duct block 402. The speed control housing 403 is equipped with a meshing gear set 405 that connects to the output end of the output motor 404. The output end of the meshing gear set 405 is equipped with a counter-rotating lead screw set 406. The counter-rotating lead screw set 406 is threadedly connected to a sliding base 407. Below the sliding base 407 is a lifting base 409 that connects to the output end of the second hydraulic cylinder 408. Below the lifting base 409 is a servo motor 4010, and the output end of the servo motor 4010 is equipped with a milling cutter head 4011.

[0024] The eccentric lead screw assembly 406 is symmetrically distributed around the central axis of the sliding base 407, and the lifting base 409 and the central axis of the servo motor 4010 are on the same straight line.

[0025] In this embodiment, when grooving is required, the output motor 404 is used to drive the meshing gear set 405 in the gearbox 403 to drive the anti-rotation screw set 406 to move the sliding base 407 adaptively. This causes the second hydraulic cylinder 408 to extend and retract, driving the lifting base 409 to adjust to a suitable height position. Finally, through the cooperation of the servo motor 4010 and the milling cutter head 4011, the product is grooved.

[0026] The adjustable cleaning component 1 includes a table frame 101, a lead screw plate 102, a plate motor 103, a sliding bracket 104, a circular frame 105, a first pneumatic telescopic rod 106, an arc-shaped shell 107, a shaft roller 108, and a cleaning brush 109. The lead screw plate 102 is provided on the top side of the table frame 101, and the plate motor 103 is provided at one end of the lead screw plate 102. The sliding bracket 104 is provided at the output end of the plate motor 103.

[0027] In this embodiment, during use, the power output of the platform motor 103 at one end of the lead screw platform 102 drives the output end to run. After the platform motor 103 outputs power and runs, the sliding bracket 104 on the lead screw platform 102 runs and moves the circular frame 105 to a suitable spacing position.

[0028] A bolt-fitted circular frame 105 is provided on the upper inner side of the sliding bracket 104, and a first pneumatic telescopic rod 106 is provided on the inner side of the circular frame 105. An arc-shaped shell 107 is provided at the output end of the first pneumatic telescopic rod 106, and a shaft roller 108 is provided on the inner side of the arc-shaped shell 107. A cleaning brush 109 is provided on the inner top side of the sliding bracket 104.

[0029] In this embodiment, the circular frame 105 is then used to penetrate the product, so that the product is attached to the mounting base 205. The first pneumatic telescopic rod 106 is activated to output power and drive the output end to run, so that the product is clamped by the cooperation of the arc-shaped shell 107 and the shaft roller 108.

[0030] The clamping and rotating assembly 2 includes a bolt base 201, a protruding plate 202, a bearing sleeve plate 203, a drive motor 204, a contact base 205, a second pneumatic telescopic rod 206, and a fixed arc clamp 207. The bolt base 201 is located above one end of the lead screw platform 102. The top side of the bolt base 201 is provided with a protruding plate 202, and the inner side of the protruding plate 202 is provided with a bearing sleeve plate 203 that is bolted together. One side of the bearing sleeve plate 203 is provided with a contact base 205 that connects to the output end of the drive motor 204, and the side of the contact base 205 is provided with a second pneumatic telescopic rod 206. The output end of the second pneumatic telescopic rod 206 is provided with a fixed arc clamp 207.

[0031] In this embodiment, when it is necessary to rotate to a suitable position, the second pneumatic telescopic rod 206 outputs and runs, which moves the fixed arc clamp 207 to move the product, causing the drive motor 204 on the bearing sleeve 203 to output and run, so that the drive motor 204 drives the product attached to the inner side of the bonding base 205 to rotate to a suitable position.

[0032] The braking component 3 includes an end-mounted frame 301, a sliding bar 302, a slider 303, a first hydraulic cylinder 304, a push rod 305, and a spherical block 306. The end-mounted frame 301 is disposed on the outer periphery of the lead screw platform 102. A sliding bar 302 is disposed on the upper side of the end-mounted frame 301, and the slider 303 is slidably connected to the sliding bar 302. A push rod 305 connected to the output end of the first hydraulic cylinder 304 is disposed on the inner side of the slider 303, and a spherical block 306 is disposed on the inner end of the push rod 305.

[0033] In this embodiment, the slider 303 on the slider bar 302 is then moved to a suitable position. After the slider 303 moves to the suitable position, the first hydraulic cylinder 304 outputs and operates, so that the push bar 305 and the spherical block 306 cooperate to clamp and position the product.

[0034] The working principle of this automotive drive shaft grooving fixture is as follows: During use, the motor 103 at one end of the lead screw plate 102 outputs power to drive the output end. After the motor 103 operates, the sliding bracket 104 on the lead screw plate 102 moves, moving the circular frame 105 to a suitable spacing position. Then, the circular frame 105 passes through the product, causing the product to adhere to the bonding base 205. The first pneumatic telescopic rod 106 is then activated, driving the output end to operate. The arc-shaped shell 107 and the shaft roller 108 work together to clamp the product. When rotation to a suitable position is required, the second pneumatic telescopic rod 206 operates, moving the fixed arc clamp 207 to move the product. This causes the drive motor 204 on the bearing sleeve 203 to operate, driving the product... After the machine 204 is in operation, it drives the product attached to the inner side of the base 205 to rotate to a suitable position. Then, the slider 303 on the sliding bar 302 moves to a suitable position. After the slider 303 moves to the suitable position, the first hydraulic cylinder 304 is in operation, and the push bar 305 and the ball block 306 cooperate to clamp and position the product. When grooving is required, the output motor 404 is in operation, which drives the meshing gear set 405 in the gearbox 403 to operate, which drives the anti-directional lead screw set 406 to move the sliding base 407 adaptively. The second hydraulic cylinder 408 is in operation to extend and retract, which drives the lifting base 409 to adjust to a suitable height position. Finally, the servo motor 4010 and the milling cutter head 4011 cooperate to achieve the effect of grooving the product.
