[0002] The motor housing is used to protect the internal components and circuits of the motor from damage by the external environment and ensure the safe and stable operation of the motor. During the production and machining of the motor housing, different machining procedures are required. For example, when cutting, drilling, grinding and polishing, and welding the housing, the housing needs to be pre-fixed. The existing fixing methods generally clamp and fix the inner and outer surfaces of the housing through a fixture. When the machine tool needs to machine the outer surface of the motor housing, the fixture is likely to interfere with the cutting tool of the machine tool, affecting the machining. Summary of the Utility Model

[0003] The purpose of this application is to solve the above problems and provide a fixture for machining a motor housing, so as to solve the technical problem that the fixture interferes with the machining of the motor housing by the machine tool.

[0004] To achieve the above purpose, this application provides a fixture for machining a motor housing, including

[0005] A base, the base includes a first locking structure provided at its top and a limiting groove for clamping with the motor housing.

[0027] Please refer to Figure 1 , this embodiment provides a machining fixture for a motor housing. Specifically, the machining fixture for the motor housing includes a base 1. The base 1 includes a first locking structure provided at its top, and a limiting groove 12 for clamping with the motor housing 100. The limiting groove 12 is arranged along the length direction of the base 1, and the first locking structure is arranged at the head and tail ends of the limiting groove 12; a pressing member 2, the pressing member 2 is arranged on the base 1. The pressing member 2 includes a supporting portion 21 and a pressing portion 22. The supporting portion 21 is arranged at the head and tail ends of the limiting groove 12. The pressing portion 22 extends from the supporting portion 21 towards the middle of the base 1 to above the first locking structure. The pressing portion 22 is provided with a second locking structure, and the second locking structure cooperates with the first locking structure to lock the motor housing 100.

[0028] Among them, the base 1 is a cuboid structure, which is convenient to be fixed on a machine tool and has characteristics such as high structural stability, high space utilization rate, simple manufacturing process, easy installation and maintenance, etc. In another embodiment, the base 1 can also be a cylindrical structure or a structure of other shapes.

[0029] The number of the limiting grooves 12 is 12, and they are arranged in parallel along the width direction of the base 1. The limiting grooves 12 limit the horizontal movement of the heat dissipation ribs on the inner wall of the motor base, and limit the horizontal movement of the motor base. The number of the limiting grooves 12 matches the number of the heat dissipation ribs on the inner wall of the motor housing 100. In another embodiment, the number of the limiting grooves 12 can also be set to 10, 14 or other numbers according to the number of the heat dissipation ribs on the inner wall of the motor housing 100.

[0030] Please refer to Figure 4 , the base 1 is further provided with a limiting boss 13 for limiting the movement of the motor housing 100 along the length direction of the base 1. The limiting boss 13 is arranged at the head and tail ends of the limiting groove 12. One side of the limiting boss 13 facing the middle of the base 1 is provided with a limiting plane 131 perpendicular to the base 1. The limiting plane 131 limits the movement of the heat dissipation ribs on the inner wall of the motor housing 100 along the length direction of the base 1, thereby limiting the movement of the motor housing 100 along the length direction of the base 1. In addition, the limiting boss 13 can also play a role in positioning the motor housing 100 on the base 1, making the assembly of the motor housing 100 more convenient. In another embodiment, the limiting plane 131 can also be an inclined plane, which matches the shape of the heat dissipation ribs of the motor housing 100.

[0031] The base 1 and the limiting boss 13 are integrally formed, which is convenient for integral processing and reduces the error caused by assembly. In another embodiment, the limiting boss 13 and the base 1 are detachably assembled by fixing methods such as screwing.

[0032] The pressing member 2 has an L-shaped plate structure, the supporting portion 21 and the pressing portion 22 are perpendicular to each other, and the supporting portion 21 is vertically arranged on the base 1. The L-shaped structure can provide more stable support, help to disperse the pressure, and reduce deformation or damage caused by excessive single-point stress. In another embodiment, the pressing member 2 can also be a T-shaped structure or a structure of other shapes.

[0033] The supporting portion 21 is vertically arranged on the limiting boss 13, which can reduce the length of the base 1 and the height of the supporting portion 21, making the structure more compact and saving costs. In another embodiment, the supporting portion 21 is not arranged on the limiting boss 13, and the two limiting bosses 13 are located in the space formed by the two supporting portions 21.

[0034] The first locking structure includes a first threaded hole 11, and the second locking structure includes a first through hole 221. A screw passes through the first through hole 221 and is threadedly connected to the first threaded hole 11. Threaded connection is convenient for fixing the motor housing 100 and facilitates disassembly and assembly.

[0035] The first threaded hole 11 is arranged on the limiting boss 13, making the first threaded hole 11 closer to the middle of the base 1, enhancing the locking stability, and can reduce the length of the base 1, making the structure more compact and reducing costs. In another embodiment, the first threaded hole 11 can also not be arranged on the limiting boss 13, and the hole distance between the first threaded holes 11 at the head and tail ends of the limiting groove 12 is greater than the distance between the two limiting bosses 13.

[0036] The number of the first threaded holes 11 at any end of the base 1 is 3, which are arranged along the width direction of the base 1, and the first through holes 221 correspond to the first threaded holes 11 one by one. The 3 first threaded holes 11 can fix the motor housing 100 more firmly on the base 1. In another embodiment, the number of the first threaded holes 11 can also be 2, 4 or other numbers.

[0037] The first threaded holes 11 are arranged at equal intervals along the width direction of the base 1, so that the force on the motor housing 100 by the pressing portion 22 is balanced, and the stability during processing is maintained. Specifically, the first threaded holes 11 are symmetrically arranged on the base 1, so that the force on the motor housing 100 is balanced, which helps to reduce deformation or damage caused by uneven force. In another embodiment, the first threaded holes 11 can also be arranged at unequal intervals along the width direction of the base 1.

[0038] The aperture of the first through hole 221 is greater than or equal to the aperture of the first threaded hole 11, so as to avoid the aperture of the first through hole 221 being too small, which may cause the screw to be unable to pass through the first through hole 221 and be threadedly connected to the first threaded hole 11.

[0039] The first through hole 221 is a U-shaped hole, and the opening of the U-shaped hole faces the middle of the base 1. The relative position of the pressing member 2 and the base 1 can be adjusted through the U-shaped hole, which is more convenient for fixing, improves the stability of the overall structure and the assembly error tolerance rate. In another embodiment, the first through hole 221 may also be a strip-shaped hole or a first through hole of other shapes.

[0040] The specific examples described above further elaborate on the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. 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.
