Description

Technical Field

[0001] The utility model belongs to the technical field of wheel hub grinding devices, and particularly relates to a grinding tool gun for facilitating the rapid grinding of wheel hub burrs. Background Technique

[0002] In the automotive manufacturing and repair industries, deburring and grinding of metal components such as wheel hubs are important steps to ensure product quality and operational safety. Sharp burrs may be generated during the manufacturing process of wheel hubs, and these burrs need to be processed by grinding tools to prevent damage to other components or cause personal injuries during assembly. Existing grinding tools, such as handheld grinding guns, have been widely used in such operations. These tools require manual control by operators to remove burrs on metal components. However, this traditional manual working method not only has low work efficiency but also easily causes operator fatigue during long-term operation, increasing the probability of errors and the risk of work-related injuries.

[0032] By providing a grip 1, a housing 2 is threadedly connected to the lower end of the grip 1.

On one side of the housing 2, a connecting member 3 is threadedly connected by a first bolt 4, and the other side of the connecting member 3 is fixedly connected to a motor 5. Therefore, the housing 2 can play a role in connecting with the motor 5. The housing 2 can provide a place for the motor 5 to operate. One side of the motor 5 is connected to a fixed rod 6. A chute 8 is provided on the outer wall of one side of the fixed rod 6. A sliding rod 9 is movably connected to the inner wall of the chute 8. One side of the sliding rod 9 is connected to a grinding mechanism 10, and the other side of the sliding rod 9 is connected to a limiting mechanism 11. The grinding mechanism 10 is correspondingly connected to the limiting mechanism 11. Specifically, the grinding mechanism 10 includes a grinding block 101. One side of the grinding block 101 is connected to a connecting rod 102. A connecting groove 104 is provided on the outer wall of the connecting rod 102. Two first limiting rings 103 are fixedly connected to the outer wall of one side of the connecting rod 102. There is a gap between the first limiting rings 103. A sleeve rod 105 is connected to the outer wall of the connecting rod 102. The connecting rod 102 can pass through the sleeve rod 105 and extend to the other side of the sliding rod 9.

The first limiting ring 103 connected to one side of the connecting rod 102 can extend to one side of the sliding rod 9 and between the two spring pieces 114. At this time, the two spring pieces 114 can be clamped with the first limiting ring 103 to limit the connecting rod 102.

[0033] As Figures 1 to 4 shown, a rotating rod 7 is connected to the outer wall of one side of the fixed rod 6. One side of the rotating rod 7 is movably connected to the motor 5. A limiting block 14 is connected to the outer wall of one side of the sliding rod 9. The limiting block 14 is provided on one side of the outer wall of the fixed rod 6. One side of the rotating rod 7 is connected to a belt 12. Tooth blocks 13 are provided on the inner wall of the belt 12. A plurality of tooth grooves 106 are annularly arranged on the outer wall of the sleeve rod 105. The tooth grooves 106 are clamped with the tooth blocks 13 provided on the inner wall of the belt 12. The connecting groove 104 is correspondingly connected to the tooth grooves 106, and the connecting groove 104 is clamped with the tooth blocks 13 connected to the inner wall of the belt 12. The belt 12 is provided between the rotating rod 7 and the second limiting ring 107.

[0034] It should be noted that a fixed rod 6 and a rotating rod 7 are respectively connected to the outer wall on one side of the motor 5. Therefore, starting the motor 5 can drive the rotating rod 7 to rotate. A belt 12 is connected to the outer wall on one side of the rotating rod 7. A number of tooth blocks 13 are arrayed on the inner wall of the belt 12. The other side of the belt 12 is connected to a sleeve rod 105 and a second limiting ring 107. A tooth groove 106 is provided in the middle of the outer wall of the sleeve rod 105. The tooth groove 106 is correspondingly connected due to the tooth blocks 13. Therefore, when the belt 12 is affected by the rotating rod 7, it can drive the sleeve rod 105 to rotate inside the inner wall of the second limiting ring 107. And the tooth blocks 13 pass through the tooth groove 106 and are clamped with a connection groove 104 opened on the outer wall of the connecting rod 102. Then it can drive the connecting rod 102 connected to the inner wall of the sleeve rod 105 to rotate, and further drive the grinding block 101 on the outer wall on one side of the connecting rod 102 to rotate. At this time, the hub can be ground.

[0035] The working principle of the above embodiment is as follows: By holding the grip 1, the device can be grasped and used. At this time, the components inside the housing 2 are activated, and the housing 2 can send an instruction to the motor 5 to make it operate. At this time, the motor 5 drives the rotating rod 7 connected to one side to rotate. The outer wall of the rotating rod 7 is connected with a belt 12, and the inner wall of the belt 12 is connected with a tooth block 13. The tooth block 13 can be clamped with the rotating rod 7. The other side of the belt 12 is clamped with the tooth groove 106 opened on the outer wall of the sleeve rod 105 through the tooth block 13, and is clamped with the connection groove 104 opened on the outer wall of the connecting rod 102 through the tooth block 13. Thus, the sleeve rod 105 can be driven to rotate inside the inner wall of the second limiting ring 107, and the connecting rod 102 drives the grinding block 101 to rotate, and then the hub can be ground. However, after long-term use, the grinding block 101 needs to be disassembled and replaced. However, the existing ones mostly adopt a threaded connection method, and the direction of rotation of the grinding block 101 should be noted during rotation. It must be rotated in the reverse direction to perform grinding, otherwise it will fall off. However, for novices, due to lack of experience, they often make operational mistakes. For this reason, a first limiting ring 103 is connected to the outer wall of the connecting rod 102 on the side far from the grinding block 101. The first limiting ring 103 can pass through the sleeve rod 105 and extend to the other side of the sliding rod 9, and is clamped with the elastic piece 114. Since the elastic piece 114 has elasticity and is in a Z shape, when the first limiting ring 103 is pulled out of the elastic piece 114, it will be deformed and contracted inward by the elastic piece 114, so that it is clamped and cannot be detached. At this time, an activity block 113 is provided. The activity block 113 is fixedly connected to the connecting shaft 112, and the connecting shaft 112 is movably connected to the fixed block 111. The activity block 113 is arranged on one side of the inner wall of the elastic piece 114. Therefore, the activity block 113 can be pushed outwards. The activity block 113 will expand the elastic piece 114 outwards. At this time, the distance between the two elastic pieces 114 becomes larger and is greater than the diameter of the first limiting ring 103. At this time, the first limiting ring 103 can be pulled out, and then the connecting rod 102 and the grinding block 101 can be disassembled and replaced, greatly increasing the practicability and avoiding the potential safety hazard problems caused by operational mistakes.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
