Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, in particular to a shaft pressing motor thrust-threading machine. Background Art

[0002] The thrust stopper for the motor is an indispensable part in the motor assembly process, that is, thrust stops are respectively installed at both ends of the motor shaft to limit the motor shaft and prevent the motor shaft from slipping out of the motor body. Specifically, the thrust stopper is a key part to ensure the quality of a motor and whether it can operate normally. However, the thrust stopper is currently inserted manually, which is not only inefficient and cannot be mass-produced, but also has high labor intensity. In the process of inserting the thrust stopper, the thrust stopper opening may be small, and it may not be able to be smoothly inserted into the motor shaft, requiring a large thrust, or the thrust stopper may not be inserted in place, and the processing quality cannot be guaranteed.

After the motor shaft is inserted into the thrust, the rear end portion will extend into the avoidance hole, and the avoidance hole will perform avoidance.

[0013] In some embodiments, the bottom mold includes: a support portion for fixing the end of the power supply motor body and a limit portion surrounding the periphery of the support portion and extending upward to abut against the side wall of the motor body;

[0014] The support part and the limiting part cooperate with each other to fix the motor body in the horizontal and vertical directions, thereby ensuring the stability of the motor body during processing.

[0015] In some embodiments, a positioning hole is provided on the support portion for the end of the motor shaft to extend into when the motor body is placed on the support portion;

[0016] By providing the positioning hole, one end of the motor shaft can be avoided, and on the other hand, the position of the motor body can be limited so that the center of the motor body and the center of the power device correspond to each other.

[0017] In some embodiments, it further comprises: a mounting bracket connected to the power device and arranged vertically on the fixing seat, wherein a long strip adjustment member connected to the power device and used for adjusting the height of the power device is vertically extended from the mounting bracket;

[0018] The installation height of the power device can be adjusted by setting a long strip adjustment, thereby adjusting the pushing stroke of the thrust, and it is suitable for processing motors of different specifications, with strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] The utility model provides a shaft pressing motor thrust-threading machine, comprising: a fixing seat 1, a bottom mold 2 arranged on the fixing seat 1 for fixing a motor body 6, a motor shaft 7 passing through the motor body 6, a power device 3 movably arranged on the fixing seat 1 and arranged opposite to the bottom mold 2, and capable of pushing the thrust 8 to move downward to a predetermined position when the thrust 8 passes through the motor shaft 7.

[0027] Specifically, the power device 3 is a cylinder, which includes a cylinder body 301 and a power shaft 302 in a hollow structure connected to the cylinder body 301. The cylinder is connected to a foot switch, and the cylinder can be started and stopped by the foot switch.

[0028] Specifically, the bottom mold 2 includes: a support portion 201 fixed to the end face of the power supply motor body 6 and a limiting portion 202 surrounding the support portion 201 and extending upward to abut the side of the motor body 6. Specifically, a positioning hole 2011 is provided on the support portion 201, into which one end of the power supply motor shaft 7 extends when the motor body 6 is placed on the support portion 201.

[0029] Specifically, both ends of the motor shaft 7 need to be sleeved with thrust stops 8 for limiting. One end of the motor shaft 7 extends out of the motor body 6 for a longer length, while the other end is shorter. During assembly, the two thrust stops 8 are manually lightly sleeved on the two ends of the motor shaft 7, and then the shorter end of the motor shaft 7 is inserted into the positioning hole 2011, so that the lower end surface of the motor body 6 abuts against the support portion 201. At this time, the foot switch is stepped on, and the power shaft 302 of the power device 3 moves downward. The power shaft 302 is a hollow structure that can avoid the motor shaft 7 in the air. The power shaft 302 pushes the thrust stop 8 to the predetermined position of the motor shaft 7.

[0030] Preferably, the present application is further provided with a positioning plate 5, which is arranged below the fixing seat 1, and a plurality of avoidance holes 501 are opened on the positioning plate 5. When it is necessary to lightly put the thrust stop 8 on the motor shaft 7, it is only necessary to place the thrust stop 8 at the position corresponding to the avoidance hole 501, and then align the motor shaft 7 with the thrust stop 8 and insert it. After insertion, the end portion of the motor shaft 7 extends into the avoidance hole 501, and finally the motor is taken out upwards, so that the thrust stop 8 can be inserted with one hand.

[0031] Preferably, the power device 3 is fixed on the fixing base 1 via a mounting bracket 4, the mounting bracket 4 is arranged vertically, and the power device 3 is connected to the mounting bracket 4 via a transverse fixing plate.

[0032] Since the extension lengths of motor shafts 7 of different specifications are different, the strokes of the power device 3 pushing the thrust stop 8 are also different. Preferably, a long strip adjustment hole 401 is vertically extended on the mounting bracket 4, and the horizontal fixing plate and the power device 3 can be locked to different heights by screws to adjust the stroke of the power shaft 302 pushing the thrust stop 8.

[0033] Preferably, a plurality of axle pressing motor thrust machines can be provided and arranged side by side on the positioning plate 5 to realize multi-station simultaneous processing.

[0034] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
