A vehicle mechanical bolt dismounting device

Abstract

The invention discloses a vehicle mechanical bolt demounting and mounting device which comprises a base, a hole groove a, a hole groove b, a rotary shaft, a gear a, an inner hexagonal sleeve, a drivemotor and a gear b. The hole groove a and the hole groove b are formed in the left side and the right side of the upper end of the base correspondingly. The rotary shaft is vertically mounted in the hole groove a. The gear a is inserted to the outer wall of the middle of the rotary shaft in a sleeving manner. The inner hexagonal sleeve is connected to the upper end of the rotary shaft in an inserted manner. The drive motor is vertically and fixedly mounted in the hole groove b. The gear b is mounted on a rotary shaft of the drive motor. A handle is vertically mounted at the lower end of the base. A rail sliding groove is fixedly mounted in the upper side of the left end of the base. A device box is mounted at the upper end of the rail sliding groove in parallel. According to the vehicle mechanical bolt demounting and mounting device, the drive motor in the hole groove b on the right side of the upper end of the base operates to drive the rotary shaft in the hole groove a to rotate, theinner hexagonal sleeve at the top end of the rotary shaft is driven to rotate synchronously to fast demount a bolt, the bolt demounting and mounting efficiency can be improved easily, the work intensity of workers is reduced, and the device is quite practical and suitable for wide use and popularization.

Problems solved by technology

[0002] At present, most of the parts on the car are fixed by bolts. When it needs to be disassembled for maintenance, a hexagonal wrench is often used to dismantle the bolts. At present, the hexagonal wrench is a curved rod with a regular hexagonal cross section and a right angle. In this method, the principle of leverage is used to disassemble, but because the arm distance of the hexagon wrench is too short, a lot of force is required for disassembly, and when there are many bolts, this method of operation is not only slow, but also takes a long time and is inefficient. , plus bolts of different specifications need to be disassembled with different hexagonal wrenches. The existing hexagonal wrenches cannot meet the interchangeability of various bolt disassembly. Secondly, some bolts on the car are embedded in narrow and long spaces, and ordinary tools can be used to remove them. During disassembly and assembly, it is often very difficult to disassemble due to the insufficient length of the connecting rod or the obstruction of other parts around it. It is also often the case that the newly removed bolts fall into some hidden gaps in the machine during disassembly and assembly. It is difficult to find, or it is difficult to remove the bolts if found, so we propose a mechanical bolt removal device
