Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding device for automotive parts. Background Technology

[0002] Automotive parts grinding equipment is an automated or semi-automatic device specifically designed for grinding, polishing, deburring, and finishing the surfaces of automotive parts. Its core function is to use a mechanical structure to drive grinding tools to contact and move relative to the surface of the parts, removing surface defects (such as burrs, flash, oxide scale, scratches, etc.) to achieve a smooth, even, or specific roughness requirement, thus meeting the assembly precision, appearance quality, and performance standards of automotive parts.

[0003] However, existing technologies still have significant shortcomings, such as: Most grinding devices can only achieve single-direction rotational grinding. If different angles or curved surfaces of parts need to be processed, the fixed positions of the parts need to be repeatedly disassembled and adjusted manually. This is not only cumbersome, but also prone to inconsistent grinding accuracy of different parts due to positioning deviation, resulting in low overall processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for automotive parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A grinding device for automotive parts includes a frame, which is hollow and has a feed inlet. A partition plate is fixedly installed inside the frame, and a shaft frame is fixedly installed on the partition plate. A rotating shaft is rotatably installed on the shaft frame, and a grinding frame is fixedly installed at one end of the rotating shaft. A grinding drive motor is fixedly installed on the grinding frame, and a grinding wheel is fixedly installed on the shaft of the grinding drive motor. A support plate is fixedly installed between the partition plate and the frame. A second drive motor and a reducer are fixedly installed on the support plate. The input end of the reducer is fixedly connected to the second drive motor, and the output end of the reducer is fixedly connected to the rotating shaft through a coupling.

[0006] Preferably, the frame has a waste outlet on one side of the feed inlet, and a waste box is slidably disposed on the waste outlet, the waste box being disposed below the grinding wheel.

[0007] Preferably, a first protective plate is fixedly installed on the frame to protect the second drive motor.

[0008] Preferably, a second protective plate is rotatably mounted on the frame to protect the grinding drive motor.

[0009] Preferably, handles are fixedly provided on the waste box, the first protective plate, and the second protective plate.

[0010] Preferably, the first protective plate has several heat dissipation holes.

[0011] Preferably, the frame is fixedly equipped with several casters.

[0012] Preferably, a protective ring is fixedly provided at the feed inlet position, and a guide plate is fixedly provided on the protective ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Power is provided by the second drive motor, which is transmitted to the rotating shaft through the reducer and coupling, driving the grinding frame, grinding drive motor and grinding wheel to rotate as a whole. At the same time, the grinding drive motor drives the grinding wheel to rotate at high speed, so that the grinding wheel can both rotate on its own to complete the grinding action and rotate with the rotating shaft to adjust the working angle. This enables all-round rotational grinding of automotive parts, eliminating the need for repeated manual adjustment of the parts position, improving grinding efficiency and processing consistency.

[0014] 2. A waste inlet is provided on the frame and a waste box is slidably installed. The waste box is located directly below the grinding wheel. The debris generated during grinding can fall directly into the waste box under the action of gravity. The waste box can be easily cleaned by pulling it out, avoiding the scattering of waste and pollution of the environment, and reducing the intensity of manual cleaning. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: The frame 1, serving as the basic load-bearing structure of the device, adopts a hollow design, forming an internal space for accommodating various functional components. A feed inlet 2 is machined into the side wall of the frame 1, through which automotive parts enter the interior of the frame 1. This feed inlet 2 is the channel for the profiles to enter the grinding operation area.

[0019] Within the hollow cavity of frame 1, partition plate 3 is fixedly installed by bolt connection. Partition plate 3 is connected to the inner wall of frame 1, dividing the internal space of frame 1 into different areas, providing a supporting carrier for the subsequent installation of components such as shaft frame 4 and support plate 9, so that each component can be arranged in an orderly manner in the corresponding positions of partition plate 3 and frame 1 according to functional requirements, ensuring the stability and functionality of the overall structure of the device.

[0020] A shaft bracket 4 is fixed to one side of the partition plate 3. The shaft bracket 4 is fixed to the partition plate 3 by bolts to form a stable support. The rotating shaft 5 is inserted into the shaft bracket 4 and cooperates with the shaft bracket 4 through bearings, so that the rotating shaft 5 can rotate stably around its own axis.

[0021] One end of the rotating shaft 5 extends away from the partition plate 3, and the end is fixedly connected to the grinding frame 6. The grinding frame 6 rotates synchronously with the rotating shaft 5. The grinding drive motor 7 is fixed on the side of the grinding frame 6 away from the rotating shaft 5, and its housing is connected to the grinding frame 6 by bolts. The output shaft of the grinding drive motor 7 faces the feed inlet 2, and the end is fixedly connected to the grinding wheel 8. The grinding wheel 8 rotates with the rotation of the output shaft.

[0022] When the grinding drive motor 7 starts, its output shaft drives the grinding wheel 8 to rotate. At the same time, the rotating shaft 5 drives the grinding frame 6, the grinding drive motor 7, and the grinding wheel 8 to rotate as a whole under the external power drive, adjusting the working angle of the grinding wheel 8 to meet the grinding needs of automotive parts.

[0023] A support plate 9 is bolted between the partition plate 3 and the inner wall of the frame 1, providing a mounting platform for the second drive motor 10 and the reducer 11. The second drive motor 10 is placed on the support plate 9, and its bottom is fixed to the support plate 9 with bolts. The output shaft of the second drive motor 10 faces the reducer 11. The reducer 11 is also mounted on the support plate 9, located next to the second drive motor 10. The input shaft of the reducer 11 is coaxially aligned with the output shaft of the second drive motor 10. The two are fixedly connected by a coupling 12 or a flange to ensure stable power transmission.

[0024] The power, after the speed and torque are adjusted by the reducer 11, is output from its output shaft. This output shaft is connected to one end of the rotating shaft 5 via a coupling 12. The coupling 12 ensures that the power is transmitted to the rotating shaft 5 without significant loss, so that the rotating shaft 5 obtains continuous and stable rotational power. When the rotating shaft 5 rotates, it synchronously drives the grinding frame 6, the grinding drive motor 7, and the grinding wheel 8 to rotate, achieving an all-round rotational grinding effect on the automotive parts.

[0025] On the side wall of the frame 1, a waste inlet 13 is provided opposite to the feed inlet 2 on the same side. The opening size of the waste inlet 13 is adapted to the waste box 14. The waste box 14 is slidably mounted on the waste inlet 13 via a slide rail or slide groove. Its installation position is directly below the grinding wheel 8, so that metal shavings and dust generated during the grinding operation can fall directly into the waste box 14 under the action of gravity. When a certain amount of waste accumulates in the waste box 14, the operator can pull it out from the waste inlet 13, clean it, and then push it back to its original position along the original trajectory to achieve centralized collection and convenient disposal of waste.

[0026] On the frame 1, corresponding to the area where the second drive motor 10 and the reducer 11 are located, a first protective plate 15 is fixedly installed with bolts. The first protective plate 15 completely covers this area, forming a closed protection to prevent external debris from entering and interfering with the operation of the components, while also preventing operators from directly contacting the operating power transmission components. On the frame 1, near the grinding drive motor 7, a second protective plate 16 is rotatably connected via a hinge. The size of the second protective plate 16 covers the outside of the grinding drive motor 7. When the device is not in operation, the second protective plate 16 is rotated to close it, protecting the grinding drive motor 7; when grinding operations are performed or maintenance is required, it can be opened by rotating it in the opposite direction without affecting normal operation.

[0027] Handles 17 are bolted to the outer ends of the waste bin 14, the outer side of the first protective plate 15, and the outer side of the second protective plate 16. The handles 17 on the waste bin 14 facilitate pull-out operation, while the handles 17 on the first and second protective plates 15 and 16 facilitate opening and closing. In addition, several heat dissipation holes 18 are machined on the first protective plate 15. These heat dissipation holes 18 are evenly distributed to ensure that the heat generated by the second drive motor 10 and the reducer 11 during operation can be dissipated in a timely manner through the heat dissipation holes 18, maintaining the components within a suitable operating temperature range.

[0028] At the bottom of the frame 1, several casters 19 are fixedly installed with bolts. The casters 19 are evenly distributed at the bottom edge of the frame 1 and are in direct contact with the ground. With the help of the rolling function of the casters 19, the operator can push the frame 1 to move the entire device, realize the transfer of the device between different work sites, or flexibly adjust the placement of the device according to the operation requirements.

[0029] A protective ring 20 is installed at the edge of the feed inlet 2 by welding or bolting. The protective ring 20 surrounds the feed inlet 2, covering its edge. When automotive parts are fed through the feed inlet 2, the protective ring 20 prevents the profile from directly contacting the edge of the feed inlet 2 and causing scratches, thus preventing damage to the profile surface or the edge of the feed inlet 2. Simultaneously, a guide plate 21 is fixedly installed on the side of the protective ring 20 facing outwards from the frame 1. The guide plate 21 is bolted to the protective ring 20 and extends inwards from the frame 1 at an angle. When automotive parts enter through the feed inlet 2, the guide plate 21 contacts the profile surface and guides the profile along a preset path through its inclined structure, ensuring the profile enters the grinding area accurately and smoothly, improving the stability of the feeding process, making the relative position of the profile and the grinding wheel 8 more compatible, and ensuring the smooth progress of the grinding operation.

[0030] Working Principle: During use, automotive parts are guided into the grinding area inside the device through the feed inlet 2 and guide plate 21. The second drive motor 10 starts, and the power is transmitted to the rotating shaft 5 via the reducer 11 and coupling 12, driving the grinding frame 6, grinding drive motor 7, and grinding wheel 8 to rotate. The grinding drive motor 7 works synchronously, driving the grinding wheel 8 to rotate at high speed, grinding the passing automotive parts. The waste generated during grinding falls into the waste box 14 below for collection. The first protective plate 15 and the second protective plate 16 protect the power components and the grinding motor, respectively. The heat dissipation holes 18 ensure heat dissipation of the power components, and the casters 19 facilitate the movement of the device. All components work together to achieve efficient and stable grinding of automotive parts, as well as convenient maintenance and transfer in the later stages.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
