Description
Technical Field
[0001] This utility model belongs to the field of automotive parts manufacturing technology, and in particular relates to a high-efficiency deburring device for steering rocker arms. Background Technology
[0002] Steering rocker arm burrs are the process of removing burrs, flash, sharp angles, and other irregular excess metal from the surface and hole edges after casting, forging, or machining.
[0003] The widely used method of manually grinding and deburring steering rocker arms with a handheld grinder has a particularly prominent drawback: the large amount of high-speed flying metal shavings and dust generated during the process. Under the strong centrifugal force of the high-speed rotation of the grinder, these shavings are sprayed outwards in a disorderly and scattered manner, which not only directly threatens the health of the operators (easily causing eye damage, skin scratches or burns), but also causes the working environment to be filled with harmful dust. At the same time, the flying shavings will contaminate the equipment, the ground and surrounding workpieces, greatly increasing the difficulty and frequency of on-site cleaning and reducing the overall work efficiency. The safety risks, environmental degradation and inefficiency caused by shavings are key pain points that the existing manual grinding process urgently needs to solve. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency deburring device for steering rocker arms to solve the problems existing in the prior art.

The output end of the second electric cylinder passes through the bottom of the slide plate and is connected to the end of the slide plate away from the second electric cylinder. At least two bearing seats are provided on the slide plate. A drill bit is connected to one end of the bearing seat and a brush is provided on the drill bit. A combined transmission wheel is provided on the output end of the second motor and is connected to the end of the bearing seat away from the drill bit. A blower is provided above the support frame and a blower mechanism is provided on the blower. A baffle is provided on the side of the support frame away from the blower mechanism. The blower mechanism can blow debris to the inside of the baffle. A discharge port is provided below the baffle and a dust suction pipe is provided below the discharge port. A support plate is provided between the support frames and a vacuum cleaner is provided above the support plate. The vacuum cleaner is connected to the dust suction pipe.
[0006] Preferably, the clamping mechanism includes a lower plate, a clamping platform, a movable clamping plate, a limiting block, and a limiting groove. The lower plate is L-shaped and is positioned above the first sliding mechanism. The clamping platform is L-shaped and positioned above the lower plate. The movable clamping plate is slidably positioned above the lower plate. The limiting groove is opened above the lower plate, and the limiting block is slidably positioned within the limiting groove.
[0007] Preferably, the first sliding mechanism includes a first electric cylinder, a T-plate, brush bristles, a ground rail, a moving block, a compression spring, and a connecting block. The first electric cylinder is disposed inside the sliding chamber, the T-plate is disposed on the output end of the first electric cylinder, the brush bristles are disposed below the T-plate, the ground rail is symmetrically disposed above the support frame, the moving block is slidably disposed above the ground rail, a lower plate is disposed above the moving block, one end of the compression spring is connected to one side of the moving clamp, one end of the connecting block is connected to the end of the compression spring away from the moving clamp, and the other end of the connecting block is connected to the lower plate.
[0008] Preferably, a support plate is provided between the support frames, and a worm motor is provided above the support plate. The output end of the worm motor is connected to the bottom of the sliding chamber.
[0009] Preferably, a receiving bin is provided on one side of the support frame, and the receiving bin is located adjacent to one end of the sliding bin.
[0010] Preferably, the blower mechanism includes an air supply pipe, a horizontal pipe, a nozzle, and a clamp. The air supply pipe is positioned above the blower, the horizontal pipe is positioned horizontally above the fixed platform, the nozzle is positioned obliquely around the horizontal pipe, and the clamp is positioned on the air supply pipe for fixing the air supply pipe.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] This invention uses a movable clamping mechanism to fix the workpiece, and a first sliding mechanism to feed it under the grinding wheel and a drill bit with a brush for automatic grinding and deburring of the hole edges. This completely avoids the operator's direct exposure to the dangerous environment of the high-speed rotating grinding wheel and flying debris, fundamentally eliminating the risk of eye and skin injuries or burns from metal debris. The integrated vacuum cleaner and suction pipe directly extract the grinding dust at the source of the material, significantly reducing the possibility of the operator inhaling harmful metal dust and developing respiratory illnesses. The directional airflow generated by the blower and air blowing mechanism forcibly blows away the grinding debris. Inside the baffle, the physical baffle effectively prevents debris from scattering randomly in all directions, strictly confining the debris to a specific path and area. The debris blown towards the baffle eventually falls into the discharge port and is collected by the vacuum cleaner through the connected suction pipe. The combined transmission wheel drives at least two grinding wheels and a drill bit with a brush to work simultaneously, enabling rapid and continuous processing of key parts of the steering rocker arm, such as the surface and hole edges. This significantly shortens the processing time per piece, reduces reliance on skilled workers, lowers labor intensity, and improves production cycle and consistency. Automated debris collection saves the cost and time of manual cleaning.
[0013] In summary, this device integrates key technologies such as automatic workpiece clamping and conveying, multi-head high-efficiency grinding, drill bit brush cleaning of hole edges, directional airflow to control debris, physical baffle sealing, and centralized dust collection system to construct a safe, clean, and efficient automated deburring work unit. It directly addresses and effectively overcomes the core defects of manual grinding, significantly improving the production efficiency and economic benefits of deburring steering arms while ensuring personnel safety and health and maintaining a good production environment.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, such as Figure 1-7As shown, the specific design of the above-mentioned key components is described below: A high-efficiency deburring device for a steering rocker arm includes a support frame 1. A sliding chamber 16 is provided above the support frame 1. A first sliding mechanism is provided inside the sliding chamber 16. A movable clamping mechanism 14 is provided above the first sliding mechanism. A platform 18 along the direction of the first sliding mechanism is provided above the support frame 1. A fixed platform 2 is provided above the platform 18. A first motor 3 is provided above the fixed platform 2. A combined transmission wheel 4 is provided on the output end of the first motor 3, and at least two grinding wheels 5 are provided on the combined transmission wheel 4. A platform 18 is provided above the support frame 1, and a convex rail 19 is provided above the platform 18. A slider 22 is provided above the convex rail 19. A slide plate 17 is provided above the slider 22. A second electric cylinder 35 is provided in the middle of the convex rail 19. The output of the second electric cylinder 35 is... The output end of the second electric cylinder 35 is connected to the bottom of the slide plate 17 and away from the electric cylinder. At least two bearing seats 23 are provided on the slide plate 17. A drill bit 24 is connected to one end of the bearing seat 23. A brush 25 is provided on the drill bit 24. A combined transmission wheel 4 is provided on the output end of the second motor 6 and is connected to the end of the bearing seat 23 away from the drill bit 24. A blower 12 is provided above the support frame 1. A blower mechanism 13 is provided on the blower 12. A baffle 7 is provided on the side of the support frame 1 away from the blower mechanism 13. The blower mechanism 13 can blow debris to the inside of the baffle 7. A discharge port 8 is provided below the baffle 7. A suction pipe 9 is provided below the discharge port 8. A support plate 11 is provided between the support frames 1. A vacuum cleaner 10 is provided above the support plate 11 and is connected to the suction pipe 9.
[0026] The clamping mechanism 14 moves horizontally within the sliding chamber 16 via the first sliding mechanism, precisely delivering the steering rocker arm to the processing station to ensure stable alignment of the workpiece and the cleaning tool. The first motor 3 drives the combined transmission wheel 4, synchronously driving at least two abrasive wheels 5 to rotate at high speed, covering the simultaneous removal of burrs on a large surface area of the workpiece. The second motor 6 drives the drill bit 24 to rotate via another set of combined transmission wheels 4. The drill bit 24 integrates a hard brush 25 to penetrate deep into the hole edge to remove burrs and sharp corners. The slide plate 17 is pushed by the second electric cylinder 35, causing the drill bit 24 and brush 25 on the bearing seat 23 to reciprocate along the convex rail 19, adapting to fine operations with different hole diameters. The high-pressure airflow generated by blower 12 is concentrated and sprayed through blower mechanism 13, forcibly blowing the debris in the processing area towards the inside of baffle 7 to prevent it from scattering. Baffle 7 forms a semi-enclosed barrier, constraining the movement trajectory of the debris to the discharge port 8. The debris falls into the dust collection pipe 9 through the discharge port 8 and is actively sucked up and collected by the dust collector 10, achieving dust source control, completely isolating human-machine contact, eliminating the risk of injury caused by high-speed debris splashing, and ensuring operator safety from the source. The three-level protection of airflow guidance, baffle 7 sealing, and negative pressure dust collection reduces the dust emission rate, effectively preventing the hazards of metal dust inhalation and maintaining cleanliness. In the production environment, the parallel grinding of dual grinding wheels 5 and the hole cleaning of adjustable brush 25 work together to shorten the processing time. The second electric cylinder 35 precisely controls the displacement of the slide plate 17, adapting to the processing of multiple hole specifications, reducing the time spent on changeover and adjustment, saving the cost of frequent replacement of manual protective equipment, reducing the time spent on equipment pollution cleaning, and the dust collection system centrally handles debris, reducing the cost of industrial waste disposal, while avoiding downtime losses due to work-related injuries. This device has significantly improved safety protection, environmental friendliness, and production efficiency, providing a standardized industrial solution for deburring steering rocker arms.
[0027] The clamping mechanism 14 includes a lower plate 42, a clamping platform 30, a movable clamping plate 31, a limiting block 37, and a limiting groove 36. The lower plate 42 is L-shaped and is positioned above the first sliding mechanism. The clamping platform 30 is also L-shaped and positioned above the lower plate 42. The movable clamping plate 31 is slidably positioned above the lower plate 42. The limiting groove 36 is located above the lower plate 42, and the limiting block 37 is slidably positioned within the limiting groove 36. Both the lower plate 42 and the clamping platform 30 are L-shaped, forming a right-angle positioning reference surface. The L-shaped lower plate 42 provides bottom support to resist vertical vibrations during grinding. The upper L-shaped clamping platform 30 constrains the workpiece. The limiting groove 36 serves as a guide rail to ensure accurate movement of the clamping plate. The limiting block 37 slides within the limiting groove 36. By placing the workpiece on the clamping platform 30 and then moving the clamping plate 31, the compression spring 32 is pushed towards one end of the lower plate 42.
[0028] The first sliding mechanism includes a first electric cylinder 26, a T-plate 27, a brush 28, a ground rail 34, a moving block 29, a compression spring 32, and a connecting block 33. The first electric cylinder 26 is disposed inside the sliding chamber 16. The T-plate 27 is disposed on the output end of the first electric cylinder 26. The brush 28 is disposed below the T-plate 27. The ground rail 34 is symmetrically disposed above the support frame 1. The moving block 29 is slidably disposed above the ground rail 34. A lower plate 42 is disposed above the moving block 29. One end of the compression spring 32 is connected to one side of the moving clamp 31. One end of the connecting block 33 is connected to the end of the compression spring 32 away from the moving clamp 31. The other end of the connecting block 33 is connected to the lower plate 42.
[0029] The first electric cylinder 26 serves as the power source, pushing the T-plate 27 to move linearly along the sliding chamber 16. The brush bristles 28 at the bottom of the T-plate 27 reciprocate to scrape the surface of the ground rail 34 during the stroke, removing debris in real time and preventing the rail from jamming. The moving block 29 and the ground rail 34 form a low-friction sliding pair, and the bearing clamping mechanism 14 moves as a whole. The compression spring 32 flexibly connects the moving clamping plate 31 and the lower plate 42 through the connecting block 33.
[0030] A support plate 20 is provided between the support frames 1, and a worm gear motor 21 is provided above the support plate 20. The output end of the worm gear motor 21 is connected to the bottom of the sliding chamber 16. A receiving chamber 15 is provided on one side of the support frame 1, and the receiving chamber 15 is located close to one end of the sliding chamber 16. The blower mechanism 13 includes an air supply pipe 38, a horizontal pipe 39, a nozzle 40, and a clamp 41. The air supply pipe 38 is provided above the blower 12, the horizontal pipe 39 is horizontally provided above the fixed platform 2, the nozzle 40 is inclined and provided around the horizontal pipe 39, and the clamp 41 is provided on the air supply pipe 38 for fixing the air supply pipe 38.
[0031] The worm motor 21 converts the rotary motion into the vertical lifting of the sliding chamber 16 through the worm gear transmission. The output end is directly connected to the bottom of the sliding chamber 16, so that the sliding chamber 16 can be lifted up and down to adapt to the tool position. The airflow from the blower 12 is introduced into the horizontal pipe 39 through the air supply pipe 38, and forms a covering jet through the nozzle 40 with a circumferential tilt of 15°-30°, covering the workpiece processing area. The tilted nozzle 40 is designed so that the airflow is close to the workpiece surface, and blows the debris into the baffle 7 area. The worm lifting ensures the accuracy of the processing reference surface, while the blower mechanism 13 achieves efficient debris guidance with minimal energy consumption, providing a safe, efficient and low-consumption standardized deburring solution for the steering rocker arm.
