Description

Technical Field

[0001] The utility model relates to the field of vehicle maintenance, in particular to a bolt breaking device for vehicle maintenance. Background Art

[0002] During the maintenance process, the bolts on the parts that need to be repaired are usually removed and then repaired. However, due to severe rust on the bolts, over-tightening, aging of the material or incorrect disassembly methods, the bolt heads may be damaged, the threads may be stripped or the bolts themselves may be broken. The bolts need to be broken. Existing bolt breaking is usually carried out by maintenance personnel manually rotating and driving the breaking device. Manually breaking the bolts takes a long time and has low breaking efficiency. In addition, some bolts cannot be removed by manpower alone, and the manual breaking effect is limited.

[0003] In view of the above problems, a bolt breaking device for vehicle maintenance is now developed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing bolt breaking, which is usually carried out by maintenance personnel manually rotating and driving the breaking device, which requires a long working time, has low breaking efficiency, and some bolts cannot be removed by manpower alone, and the manual breaking effect is limited, the utility model provides a bolt breaking device for vehicle maintenance.

[0005] The technical solution of the utility model is: a bolt breaking device for vehicle maintenance, including a rotating component, a removal component is connected to the rotating component, a lower pressure frame is connected to the lower pressure frame, four racks are connected to the lower pressure frame, a mounting frame is slidably connected to the lower pressure frame, four gear parts are connected to the mounting frame, the gear parts are all meshed with adjacent racks, four cutters are slidably connected to the mounting frame, and the cutters are all threadedly connected to adjacent gear parts.

[0006] Furthermore, a driving motor is included. The driving motor is installed inside the rotating assembly. A cam is connected to the output shaft of the driving motor. A cover plate is connected to the right side of the rotating assembly.

[0007] Furthermore, a handle is provided at the lower portion of the rotating assembly for maintenance personnel to grasp.

[0008] Furthermore, a limiting plate for limiting the position of the adjacent gear parts is connected to the pressing frame.

[0009] Furthermore, the cutting tools all have inclined surface structures.

[0010] Furthermore, the cover plate is a detachable connection structure.

[0011] By adopting the above technical scheme, the utility model has the following advantages: the utility model drives the removal part to break the nut through the rotating component to deal with the situation that the bolt head is damaged, the thread is stripped or the bolt itself is broken. When the installation frame is pressed down, the gear part moves on the rack and drives the tool to tighten inward to clamp the bolt. In this way, the bolt is further clamped to speed up the speed of breaking the bolt. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A bolt breaking device for vehicle maintenance, such as Figure 1 and Figure 2 As shown, it includes a rotating component 1, a handle is provided at the lower part of the rotating component 1 for maintenance personnel to grasp, a removal component 2 is connected to the rotating component 1, a lower pressing frame 6 is connected to the rotating component 1, a limit plate for limiting the adjacent gear component 5 is connected to the lower pressing frame 6, four racks 7 are connected to the lower pressing frame 6, a mounting frame 3 is slidably connected to the lower pressing frame 6, four gear components 5 are connected to the mounting frame 3, the gear components 5 are all meshed with adjacent racks 7, four cutters 4 are slidably connected to the mounting frame 3, the cutters 4 are all inclined structures, and the cutters 4 are all threadedly connected to the adjacent gear components 5.

[0018] like Figure 3 As shown, a driving motor 8 is also included. The driving motor 8 is installed inside the rotating component 1. A cam 9 is connected to the output shaft of the driving motor 8. A cover plate 10 is connected to the right side of the rotating component 1. The cover plate 10 is a detachable connection structure.

[0019] During the maintenance process, it is usually necessary to remove the bolts on the parts that need to be repaired and then perform maintenance on them. However, the bolt head may be damaged, the thread may be stripped, or the bolt itself may be broken due to severe rust on the bolt, over-tightening, aging of the material, or incorrect disassembly methods. In this case, the bolt needs to be broken. The operator first turns on the rotating assembly 1, presses the pressing frame 6 downward at the corresponding position of the bolt, so that the gear part 5 rotates inward, and at the same time drives the tool 4 to tighten inward, so that the tool 4 clamps and fixes the bolt. When the mounting frame 3 moves to the extreme position, the mounting frame 3 contacts the limit plate on the pressing frame 6, and then the removal part 2 rotates and removes the bolt. The clamping effect of the tool 4 on the bolt can cope with the situation that the bolt is severely rusted and difficult to disassemble with an ordinary wrench. During the bolt breaking process, the drive motor 8 is started, and the output shaft of the drive motor 8 drives the cam 9 to rotate, thereby enhancing the vibration effect of the device, which is beneficial to the oxide on the surface of the rusted bolt falling off due to vibration, and is convenient for accelerating the bolt breaking speed.

[0020] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the 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.
