Description
Technical Field
[0001] The utility model belongs to the technical field of tooling components, and in particular relates to a dual-purpose tooling suitable for disassembly and assembly of electric motors. Background Art
[0002] The motor housing assembly contains four evenly distributed magnets, exerting a strong magnetic attraction on the armature assembly. The armature assembly and end cap assembly are connected via a main shaft, leaving no gap between the end cap and housing assembly after assembly. During disassembly and assembly, the housing assembly is a separate unit, while the armature, end cap, and main shaft are another separate unit. Currently, during motor disassembly and assembly, operators rely on their experience. After prying open the gap between the end cap and housing, they place their feet on the edge of the end cap assembly, reach into the pried-open gap, and quickly pull the housing assembly out, overcoming the magnets' attraction. This disassembly process can easily damage the end cap and is extremely dangerous, with numerous finger pinching and bleeding incidents. The assembly process is the reverse of the disassembly process. When lowering the housing assembly, operators must overcome the magnets' attraction and maintain a firm grip to prevent it from snapping together and generating a strong impact that could damage components. This results in inefficient disassembly and assembly, and can easily lead to operator injury. In order to improve the efficiency of motor disassembly and assembly operations and ensure the personal safety of operators, it is necessary to design a dual-purpose tool suitable for disassembly and assembly of motors. Utility Model Content
[0003] The purpose of the utility model is to provide a tool for disassembling and assembling an electric motor, thereby solving the problem of low quality and efficiency of the disassembly and assembly operations of the electric motor, and at the same time ensuring the personal safety of the operator.
[0004] The technical solution of the utility model is as follows: a dual-purpose tool suitable for disassembly and assembly of electric motors, comprising a base weldment, a clamping arm, a clamping claw, a cross bar and a handle threaded rod; four pillars are pre-embedded and welded on the base weldment, including two cylindrical pillars and two rectangular pillars; cross bars are installed on the two cylindrical pillars, and the handle threaded rod is installed on the cross bars, and is assembled with the cross bars through screws to form a support structure for the handle threaded rod; the two rectangular pillars are used to support the clamping arm to provide clamping force support therefor.
[0005] The clamp arm is mounted between two rectangular pillars. It consists of two front and rear arms, each with pre-embedded ball-end setscrews that secure it to the pillars. After the ball-end setscrews are inserted into the pillars, tightening and loosening the front and rear arms is achieved by rotating the screws with a wrench. The inside of the clamp arm is fitted with anti-slip and protective rubber pads to protect the motor housing assembly.
[0006] The left and right clamps are mounted on the handle's threaded rod, respectively, and tightened and released via a threaded pair. The left and right clamps are designed with through-holes and threaded holes, respectively. Screws tighten the clamps, axially positioning the motor's end cap assembly and the handle's threaded rod. The motor's housing assembly is secured to the clamp arm. After the clamps are tightened, the handle's threaded rod is rotated, allowing the threaded pair to slowly move the end cap assembly axially within the housing assembly.
[0007] The beneficial effects of the present invention are as follows: the disassembly and assembly operations of the electric motor are optimized, and the threaded rod of the handle is manually rotated, and the threaded pair can be used to slowly move the end cover assembly axially within the housing assembly. The manual rotation is highly controllable, sensitive, and easy to operate; the threaded pair design can adjust the relative position of the end cover assembly and the housing assembly at any time, preventing the problem of rapid attraction and impact damage to the product due to the inability to overcome the magnetic adsorption force when the end cover assembly is carried. Therefore, the present invention can solve the problem of damage to the end cover assembly caused by manual disassembly and assembly of the electric motor, and the quality of the components can be guaranteed during the disassembly and assembly operations, the personal safety of the operator can be guaranteed, the safety hazard of parts damage is eliminated, costs are saved, and the quality and efficiency of the disassembly and assembly of the product are improved.
