Description

Technical Field

[0001] The invention relates to the technical field of automobile rear axle processing, and in particular to a cutting device for an electric vehicle rear axle with a feeding mechanism. Background Art

[0002] In the processing of rear axle shafts of electric vehicles, the fixation of the rear axle shaft is a key link in the cutting process. Traditional clamps require manual adjustment of the clamping force, which is cumbersome to operate and difficult to ensure clamping stability. Especially during high-speed cutting, the shaft is easily displaced or deflected due to vibration. The clamping mechanism may also loosen due to reverse force under continuous external force, affecting the processing accuracy. At the same time, when the shaft needs to be rotated, the traditional fixing device needs to be removed and rotated again. The existing technology makes it difficult to flexibly switch the rotation state of the shaft during the processing process. If rotary cutting is required, it depends on an additional drive device, which makes the equipment structure complex.

[0003] When cutting shafts, existing cutting equipment mainly uses a three-jaw chuck and a cylinder to clamp the shaft, which makes it difficult to quickly disassemble and assemble the rear axle shaft. At the same time, loading is mostly done manually, which is also relatively difficult. Therefore, we propose a cutting device for the rear axle shaft of an electric vehicle with a loading mechanism.

The outer wall of the sliding sleeve is fixedly connected to the fixed plate, and the outer wall of the fixed plate is rotatably connected to the inner wall of the rotating plate. The outer wall of the rotating plate is rotatably connected to the inner wall of the rotating plate, and the sliding rod is rotatably connected to the cover plate. The rotation of the motor drives the rotating rod to rotate, so that the mutually meshing convex plate and the concave plate meet and rotate, and drive the ratchet to rotate. When the rotating rod is moved, the convex plate and the concave plate fail to mesh, the ratchet stops rotating, and the limit block and the ratchet are locked with each other to prevent reversal.

Since the shaft and the sleeve are in direct contact, the cutting shaft is rotated to achieve a better cutting purpose. At the same time, when the shaft does not need to rotate, the limit rod is rotated, the inner gear disc is rotated, and the gear is rotated, and the toothed plate starts to rotate until the outer gear cylinder is fixed, thereby achieving the purpose of fixing the sleeve, thereby controlling whether the shaft rotates.

When the cylinder is started, the cylinder extends to push the processing shaft out. Due to the action of the inclined plate, the processing shaft rolls into the guide block. At this time, the push rod is compressed under the action of the gravity of the processing shaft, causing the triangular plate to move downward, and the roller starts to slide on the triangular plate, thereby causing the gripper to rotate on the support rod. At this time, the processing shaft is clamped by the gripper, and the telescopic rod extends from the limit plate, and at the same time drives the fixed rod to slide on the limit plate, thereby causing the positioning rod to rotate in the slot, thereby driving the baffle to rotate, and the gripper starts to rotate, thereby causing the compression spring to move and be tightened until the processing shaft is sent to the fixing device.

[0010] Preferably, the end of the compression spring away from the baffle is rotatably connected to the outer wall of the telescopic rod, the outer wall of the positioning rod is rotatably connected to the inner wall of the telescopic rod, the inner wall of the baffle is rotatably connected to the outer wall of the grip, the outer wall of the baffle is rotatably connected to the outer wall of the fixing rod, and the outer wall of the roller is rotatably connected to the inner wall of the grip.

[0013] The present invention has the beneficial effects: 1. The present invention provides a fixing device. When the fixing device starts working, the fixing device is moved to one side of the shaft by rotating the handle. At this time, the conveyor belt rotates, which in turn drives the turntable to rotate, thereby moving the sliding rod, and then clamping the shaft to achieve the effect of fixing the shaft. When the sliding rod is moved, the convex plate and the concave plate lose engagement, and the rotation stops at this time. Under the action of the ratchet, the turntable is prevented from reversing, making the shaft clamping ineffective. This mutual extrusion generated by the contact between the sliding rod and the shaft prevents the shaft from shaking during cutting.

[0014] 2. The present invention sets a fixing device. When the shaft is clamped by the sliding rod, the shaft is in direct contact with the sleeve. At this time, the shaft is cut and the shaft will rotate to achieve a better cutting purpose. At the same time, when the shaft does not need to rotate, the rotation limit rod rotates the inner gear disc and drives the gear to rotate. At the same time, the tooth plate starts to rotate until the outer gear cylinder is fixed, thereby achieving the purpose of fixing the sleeve, thereby controlling whether the shaft rotates.

[0015] 3. The present invention is provided with a feeding device. When the cylinder is pushed out, the shaft starts to slide under the action of the inclined plate and slides into the gripper. At this time, the push rod is squeezed, causing the triangular plate to move downward, so that the gripper clamps the shaft. At this time, the telescopic rod extends and drives the gripper to rotate until the shaft is sent to the fixing device. When the shaft is clamped by the fixing device, the push rod loses the squeezing force, the gripper opens, the telescopic rod retracts, and the gripper is pulled to its original position by the spring. The device is reset, thereby achieving the purpose of feeding.

[0016] 4. The present invention is provided with a cleaning device. When the driving wheel rotates, the rocker is driven to rotate, and at the same time the slider starts to slide in the movable plate, and drives the scraper to do reciprocating motion. At this time, the cut debris is scraped to both sides by the scraper. At the same time, due to the rotation of the eccentric wheel, the vibration plate will be driven to vibrate up and down. Since the vibration plate is in an inclined state, the debris will be concentrated at one end, thereby achieving effective cleaning of the debris, and also ensuring that the equipment remains well clean.

[0029] Working principle: When the rear axle of the electric vehicle needs to be cut, the feeding device 4 is started and the cylinder 42 is opened. At this time, the cylinder 42 extends to push the rear axle of the electric vehicle out. Due to the action of the tilting frame 40, the rear axle rolls onto the guide block 41. At this time, the push rod 471 is compressed under the action of the gravity of the rear axle, thereby causing the triangular plate 472 to move downward. At the same time, the roller 475 starts to slide on the triangular plate 472, thereby causing the gripper 473 to rotate on the support rod 474. At this time, the rear axle is clamped by the gripper 473 and stretched at the same time. The retractable rod 45 extends, and at the same time drives the fixed rod 44 to slide on the limit plate 43, so that the positioning rod 48 rotates in the slot 46, and then drives the baffle 47 to rotate, and at the same time the gripper 473 starts to rotate, thereby tightening the compression spring 476 until the processed rear axle shaft is sent to the fixing device 3. When the rear axle shaft is clamped, the push rod 471 loses the extrusion force, the gripper 473 opens, and the telescopic rod 45 retracts. Under the action of the compression spring 476, the gripper 473 is pulled back to its original position, and the device is reset.

[0030] When the power device 2 is started and the motor 20 is turned on, the motor 20 starts to rotate, thereby driving the rotating rod 27 to rotate, and the convex plate 22 rotates, thereby driving the concave plate 23 to rotate, and the rotating rod 24 starts to rotate, and drives the ratchet 25 to rotate, and drives the limit block 26 to rotate. When the ratchet 25 rotates, the belt set pulley 29 starts to rotate and drives the turntable 31 to rotate, thereby driving the sliding rod 36 to rotate on the fixed plate 32, and then turning the handle 312, and the threaded rod 311 rotates. At this time, the slider 310 starts to slide, and due to the action of the fixed rod 211, the roller 210 and the belt set pulley 29 slide, and the fixing device 3 moves, and the telescopic cylinder 313 is pressed until the processing shaft is clamped by the sleeve 35. At this time, the sliding push-pull rod 21 causes the convex plate 22 to move away from the concave plate 23, thereby causing the engagement to fail. At the same time, the limit block 26 and the ratchet 25 are locked, and the fixed wheel 28 is fixed to the base 1 to prevent reversal and the tightening failure of the sleeve 35.

[0031] The cutting device 5 is started, the saw teeth begin to rotate and move in the slide until they move to the rear axle shaft. When the rear axle shaft is cut, the cleaning device 6 is started at the same time, the motor 60 is turned on, the motor 60 rotates, and drives the driving wheel 61 to rotate, and at the same time drives the rocker 62 to rotate. At this time, the moving block 64 slides in the moving plate 63, thereby driving the scraper 65 to reciprocate, scraping the debris cut on the filter plate 67 onto the vibrating plate 660. Due to the rotation of the motor 60, the eccentric rod 66 rotates, which causes the vibrating plate 660 to move up and down on the fixed block 661. At the same time, under the action of the buffer spring 662, the vibrating plate 660 can work better, so that the debris can be better collected. Under the action of the telescopic cylinder 313 and the cover plate 39, the debris can be prevented from entering the thread of the threaded rod 311 and the tooth groove of the fixing device 3.

[0032] At the same time, under the action of the sleeve 35, the rear axle shaft rotates while being cut, so that the rear axle shaft is cut more effectively. When the rear axle shaft does not need to be rotated further, the limit rod 38 is pushed, causing the inner gear plate 34 to rotate relative to the rotating plate 33, thereby driving the gear 341 to rotate. The rotation of the gear 341 causes the gear plate 342 to mesh with the outer gear cylinder 343, so that the outer gear cylinder 343 and the sleeve 35 are fixed, preventing the sleeve 35 from rotating. When the cutting is completed, the telescopic rod 45 retracts and the gripper 473 returns to its original position under the action of the compression spring 476, and the above movement is repeated.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
