Description

Technical Field

[0001] The utility model relates to the technical field of motor shell processing, in particular to a shell processing device for direct current motor processing. Background Art

[0002] The housing of a DC motor is typically made of metal, such as aluminum alloy, cast iron, or steel. Its primary function is to protect the internal mechanical and electrical components while providing mechanical strength and structural support. During DC motor production, the housing undergoes sandblasting. This treatment removes dirt, oxide layers, coatings, and paint, leaving the surface clean and smooth while also increasing roughness, ensuring better adhesion for subsequent surface treatments such as painting and electroplating.

[0003] The utility model with announcement number CN221088664U discloses a casing processing device for DC motor processing, including a device main body, which includes a mounting base, a material box, a material feed channel, a sandblasting tube and a sandblasting head. The device main body also includes an anti-diffusion mechanism, which is arranged at the top of the mounting base and includes a sealed box body, a glass cover plate and a glove connector.

[0004] The existing casing processing device is equipped with a sealed box, a glass cover and a glove connector. With this design, during the actual sandblasting process, the worker can connect the operating glove body to the glove connector and use the gloves to operate to avoid leakage of sand and dust. However, this method of operation with gloves is prone to causing damage to the operator's hands due to the high-speed flow of sandblasting. On the other hand, the sand layer formed on the surface of the motor casing after sandblasting is easily damaged by hand operation, affecting the efficiency and quality of the motor casing processing.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, the utility model provides two technical solutions:

[0029] The first embodiment: A shell processing device for DC motor processing includes a processing box 1, a shell placement component 2, a driving component 3 and an adjusting component 4.

[0030] A door 11 is provided at the opening of the processing box 1. Grooves 15 are provided on the inner walls of both ends of the processing box 1. A sandblasting box 12 is provided on the top of the processing box 1. The output end of the sandblasting box 12 is connected to a sandblasting head 13, so that the device can perform sandblasting. The back of the sandblasting box 12 is connected to the lower end of the inner cavity of the processing box 1 through a circulation pipe 14. A circulation fan is provided on the circulation pipe 14, so that the sand and gravel accumulated after sandblasting can be recycled.

[0031] There are two shell placement pieces 2, which are symmetrically arranged in the inner cavity of the processing box 1 and are used to place the motor 35 shell. The shell placement piece 2 includes a connecting plate 21 arranged at both ends of the inner cavity of the processing box 1. A plurality of brackets 22 distributed in a circular array are fixed to the edge of one side of the connecting plate 21. The two adjacent brackets 22 are connected by a protective net 23 to form a cylindrical structure. A rubber block 24 is bonded to the inner side of the bracket 22. The setting of the rubber block 24 protects the motor 35 shell. The middle part of the other side of the connecting plate 21 is connected to the inner wall of the processing box 1 through a sealing belt 25.

[0032] The driving member 3 is provided at both ends of the processing box 1 for driving the outer shell placement member 2 to rotate. The driving member 3 includes a slot 31 opened at one end of the bracket 22. The opening of the slot 31 extends to the other side of the connecting plate 21. A plug-in plate 32 is inserted into the slot 31. One end of the plug-in plate 32 is connected to the bottom of the slot 31 through a spring. A ring gear 33 is fixed to the other end of the plug-in plate 32. One end of the ring gear 33 is movably connected to the side wall of the groove 15 through a sealed bearing. The top of the ring gear 33 is meshed with a driving gear 34. A motor 35 is fixed to the upper part of both ends of the processing box 1. The output shaft of the motor 35 passes through the side wall of the processing box 1 and is fixedly connected to the middle of the driving gear 34. The motor 35 drives the driving gear The wheel 34 rotates, and the driving gear 34 drives the ring gear 33 to rotate. The ring gear 33 drives the outer shell placement part 2 to rotate through multiple plug plates 32, and flips the outer shell of the motor 35 inside it so that the outer shell of the motor 35 can be sandblasted. The driving part 3 also includes a first cylinder 36 fixed to the middle part of the upper side of both ends of the processing box 1. The output end of the first cylinder 36 passes through the side wall of the processing box 1 and is movably connected to a guide wheel 37 through a pin shaft. The guide wheel 37 is fitted with the other side of the connecting plate 21. The first cylinder 36 can push the outer shell placement part 2 to move, so that the two outer shell placement parts 2 can cooperate to limit the outer shell of the motor 35. The setting of the guide wheel 37 makes the output end of the first cylinder 36 not affect the rotation of the connecting plate 21.

[0033] The second embodiment is mainly different from the first embodiment in that: the adjusting member 4 is provided at both ends of the processing box 1, a part of the adjusting member 4 is located inside the shell placement member 2, and the two adjusting members 4 are used to limit the shell of the motor 35. The adjusting member 4 includes a fixing plate 41 fixed in the middle of the two ends of the processing box 1, and the bottom end of the fixing plate 41 is fixed to the processing box 1 through a reinforcing plate 42. A linear guide 43 is provided on the upper surface of the fixing plate 41. The linear guide 43 is fixed with a second cylinder 44 by bolts, and the linear guide 43 can drive the shell with the first cylinder 36 The placement part 2 drives the second cylinder 44 to move at the same time. The output end of the second cylinder 44 passes through the through grooves opened in the middle of the processing box 1 and the connecting plate 21 in sequence and is movably connected to the movable pressure plate 45 through a bearing. The output end of the second cylinder 44 is connected to the sealing belt 25. The movable pressure plate 45 is located in the inner cavity of the outer shell placement part 2. The second cylinder 44 drives the movable pressure plate 45 to move. The two movable pressure plates 45 cooperate to limit the outer shell of the motor 35, so that the outer shell of the motor 35 can be flipped at the moving angle as the outer shell placement part 2 rotates, thereby improving the sandblasting efficiency of the device.

[0034] When the device is working, the box door 11 is first opened, and then the motor 35 housing is placed between the two housing placement parts 2, and then the first cylinder 36 is started. The first cylinder 36 drives the connecting plate 21 to move, and then drives the housing placement part 2 to move until the motor 35 housing is located between the two housing placement parts 2, and then continues to move the housing placement part 2 until the two housing placement parts 2 are located on both sides of the sandblasting head 13. During this process, the second cylinder 44 moves with the linear guide 43. When the linear guide 43 stops driving, the second cylinder 44 is started. The second cylinder 44 drives the movable pressure plate 45 to move until the two movable pressure plates 45 cooperate to limit the motor 35 housing to a certain range of areas, so that the sandblasting head 13 can sandblast the motor 35 housing. Then the motor 35 is started, and the motor 35 drives the driving gear 34 to rotate. The driving gear 34 drives the ring gear 33 to rotate. The ring gear 33 drives the connecting plate 21 to rotate through multiple plug plates 32, and then drives the housing placement part 2 to rotate, so that the motor 35 housing is flipped in the housing placement part 2, thereby improving the sandblasting efficiency of the device.
