Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, specifically to an angle grinder for vehicle frame processing. Background Technology

[0002] An angle grinder is needed for cutting or grinding during the manufacturing of the vehicle frame. An angle grinder is a tool used for cutting, grinding, and brushing metals and stones.

[0003] Chinese Patent CN221604004U discloses an angle grinder for processing motorcycle frames, including a support frame. When processing a motorcycle frame, the height of the angle grinder body is adjusted according to the height of the motorcycle frame. The first motor is turned on, causing the first motor to drive the threaded disc upward via the first threaded rod. The threaded disc then drives the connecting plate upward via the sliding rod, which in turn drives the angle grinder body upward. The angle grinder body then grinds the motorcycle frame. When cutting the motorcycle frame, the grinding disc of the angle grinder body is replaced, and the second motor is turned on. The second motor drives the worm gear to rotate via the worm, which in turn drives the support plate to rotate via the short rod. The support plate then drives the angle grinder body to rotate via the fixing plate, allowing the angle grinder body to rotate into a vertical position. The angle grinder body can then cut the motorcycle frame.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: When the angle grinder body processes the frame, it will generate a large amount of debris and dust, which will not only pollute the processing table and the frame, but the debris and dust falling on the frame will also interfere with the finishing of the frame and reduce processing efficiency.

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 3 As shown, the present invention proposes an angle grinder for vehicle frame processing, including a housing 1 and a protective cover; a drive motor 101 is installed inside the housing 1, and the housing 1 is detachably installed on a fixed plate in an existing mechanism adjustment frame. The output end of the drive motor 101 extends to the outside of the housing 1 and a grinding disc 102 is detachably installed thereon; the protective cover is detachably installed on the housing 1 and covers the outside of the grinding disc 102. The protective cover consists of two sets of fitted shells 2 and a suction pipe 206 installed on the rear side wall of one set of shells 2. A disassembly and assembly mechanism is provided between the top ends of the two sets of shells 2. The two sets of shells 2 are detachably connected to the housing 1 through the disassembly and assembly mechanism. Each top end of the shell 2 is provided with a clearance opening 203. The clearance openings 203 on the two sets of shells 2 are located around the output end of the drive motor 101 to avoid affecting the drive motor 101 driving the grinding disc 102 to rotate. The other end of the suction pipe 206 is connected to an external vacuum cleaner.

[0020] Furthermore, the disassembly and assembly mechanism includes a first connecting seat 3, a second connecting seat 5, and a strap 4; the first connecting seat 3 is installed on the top of one set of housings 2; the second connecting seat 5 is installed on the top of another set of housings 2, the first connecting seat 3 and the second connecting seat 5 are in contact with the outer wall of the chassis 1, and a channel 501 is opened inside the top of the second connecting seat 5; one end of the strap 4 is installed on the first connecting seat 3, and a slot 301 is opened inside the other end of the first connecting seat 3, a limiting component is provided on the slot 301, the other end of the strap 4 passes through the channel 501 and extends into the slot 301, and the strap 4 is connected to the slot 301 through the limiting component.

[0021] Furthermore, the limiting component consists of a slidingly inserted abutment rod 302 of the first connecting seat 3 and a spring 303 sleeved on the outside of the abutment rod 302. The insertion end of the abutment rod 302 extends into the slot 301. One end of the spring 303 is connected to the end of the abutment rod 302 away from the insertion end, and the other end of the spring 303 is connected to the outer wall of the first connecting seat 3.

[0022] Furthermore, the inner wall of the strap 4 is provided with a rubber pad 402 to increase the friction at the contact point with the chassis 1 and prevent slippage. The strap 4 is made of PVC material, which has a certain degree of flexibility and hardness. The outer wall of the strap 4 is provided with an anti-slip part 401, and the insertion end of the contact rod 302 abuts against the anti-slip part 401 to increase the friction at the contact point and prevent slippage.

[0023] Furthermore, one set of housings 2 is provided with a docking groove 201, and the other set of housings 2 is provided with a corresponding insertion rod 202. The insertion rod 202 is inserted into the docking groove 201 to improve the installation stability of the two sets of housings 2 and facilitate the alignment and docking of the two sets of housings 2, which is convenient for the installation of the disassembly and assembly mechanism.

[0024] In this embodiment, the chassis 1 is installed on the fixed plate in the existing mechanism adjustment frame, the grinding disc 102 is installed on the output end of the drive motor 101, and the two sets of housings 2 are aligned and fitted together through the mating groove 201 and the insert rod 202, and the two sets of housings 2 are surrounded on the outside of the grinding disc 102. At this time, the two sets of clearance openings 203 are located on the periphery of the output end of the drive motor 101. At this time, the first connecting seat 3 and the second connecting seat 5 are fitted with the outer peripheral surface of the chassis 1, and the channel 501 is mated with the slot 301. The abutment rod 302 is held and slid along the slot 301 to stretch the spring 303. Then, the end of the strap 4 away from the first connecting seat 3 is passed through the channel 501 until it is inserted into the slot 301. In the middle, the rubber pad 402 abuts against the outer peripheral surface of the chassis 1. At this time, the abutment rod 302 is released. Under the elastic force of the spring 303, the abutment rod 302 is driven to tighten the strap 4 into the slot 301. The anti-slip part 401 increases the friction at the abutment rod 302 and the strap 4, preventing slippage. Then the protective cover can be quickly installed on the outside of the grinding disc 102. The external vacuum cleaner is connected to the vacuum pipe 206. When the controller starts the drive motor 101 to drive the grinding disc 102 to rotate, the vacuum pipe 206 can absorb the debris or dust generated during processing, avoiding contamination of the processing table and the frame, avoiding interference with the finishing of the frame, and improving processing efficiency.

The top of the guide rod 204 is slidably connected to the guide seat 205, and the guide rod 204 is designed to be L-shaped.

[0027] In this embodiment, the guide rod 204 and guide seat 205 facilitate the quick alignment and bonding of the two sets of housings 2 along the bottom of the chassis 1, and prevent the housings 2 from separating from the chassis 1 along the height direction of the chassis 1, thereby improving installation stability.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
