DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] like Figure 1-4 As shown, an embodiment of the present application discloses a motor cover press-fitting device, including a workbench 10, on which a positioning seat 20 and a press-fitting assembly 30 are provided. The positioning seat 20 is used to place the motor housing, and the press-fitting assembly 30 is used to press the motor cover into the motor housing.

[0029] Specifically, the positioning seat 20 is arranged in the middle of the table surface of the workbench 10, and is a column with a hollow middle part and a vertical opening 21 on the front side. A limit block 22 cooperating with the motor housing is arranged on the top of the positioning seat 20, so that the motor housing can be supported and positioned by placing the motor housing on the positioning seat 20. Since the motor shaft has been assembled when the motor housing and the motor cover are assembled, the motor shaft will protrude from both ends of the assembly of the motor housing and the motor cover. A horizontal notch 11 connected to the vertical opening 21 of the positioning seat 20 is opened on the table surface of the workbench 10 from the front side to the middle, so that the assembly of the motor housing and the motor cover can be placed on the positioning seat 20 in a horizontal state, which is convenient for the robot to operate.

[0030] The press-fitting assembly 30 is arranged directly above the positioning seat 20, and includes a plurality of support columns 31 arranged on the table surface of the workbench 10. A top plate 32 is commonly arranged on the top of the plurality of support columns 31. A press-fitting motor 33 is arranged in the middle of the top plate 32. The output shaft of the press-fitting motor 33 passes through the top plate 32 downward and a guide plate 35 is arranged at the end. A plurality of guide columns 36 are arranged vertically on the guide plate 35. A guide hole 321 is opened in the top plate 32 corresponding to the position of the guide column 36. A guide sleeve 37 is arranged at the lower end of the guide hole 321. The guide column 36 passes through the guide sleeve 37 and the guide hole 321 and forms a sliding guide fit with the guide sleeve 37. A press-fitting head 34 is arranged at the bottom of the guide plate 35. In this way, when the press-fitting motor 33 drives the guide plate 35 and the press-fitting head 34 to move up and down, the press-fitting head 34 can be guaranteed to always move in the vertical direction under the cooperation of the guide column 36 and the guide sleeve 37 without deviation. The tops of the guide posts 36 are connected by a connecting plate 38, so that when the press motor 33 drives the guide plate 35 to move downward, the guide posts 36 will not separate from the guide sleeve 37. Further, a pressure sensor 39 is provided between the output shaft of the press motor 33 and the guide plate 35, so that the press force of the motor cover during each assembly can be detected.

[0031] The press head 34 is in the shape of a column with a blind hole 341 formed upward from the bottom, and a vertical notch 342 connected to the blind hole 341 is formed vertically on the front side of the press head 34. When the motor housing and the motor cover are put into the positioning seat 20, the motor shaft at the upper end can directly enter the blind hole 341 from the vertical notch 342, so when the press head 34 is pressed down, there is no need to consider the problem of the press head 34 and the motor shaft matching, which prevents the blind hole 341 of the press head 34 from misaligning with the motor shaft, making the operation more convenient.

[0032] A mounting seat 40 is provided on each side of the positioning seat 20 on the table top of the workbench 10, and a driving cylinder 41 is provided on the mounting seat 40. The telescopic rod of the driving cylinder 41 is horizontally arranged toward the positioning seat 20 and a clamping block 42 is provided at the end. After the motor cover is pressed into place, the driving cylinder 41 drives the clamping block 42 to move toward the positioning seat 20, and the buckle ears on both sides of the motor cover are clamped onto the motor casing, thereby ensuring the tight connection between the motor cover and the motor casing.

[0033] The use principle of a motor cover pressing device in the present embodiment is: first install the motor cover on the motor casing, and then put the assembly of the motor casing and the motor cover on the positioning seat 20. Due to the existence of the vertical opening 21 and the horizontal notch 11, the assembly of the motor casing and the motor cover can directly enter the device horizontally without tilting, thereby reducing the operating space; then the pressing motor 33 drives the guide plate 35 and the pressing head 34 to move downward to press the motor cover into place; finally, the driving cylinders 41 on both sides drive the clamping blocks 42 to move toward the positioning seat 20, and the buckle ears on both sides of the motor cover are clamped onto the motor casing to complete the assembly of the motor casing and the motor cover. The operation is simple, the work efficiency is high, and automated production can be achieved.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
