Description

Technical Field

[0001] The utility model relates to a motor end cover pressing mechanism, belonging to the motor end cover pressing field. Background Art

[0002] During the assembly of the motor, it is necessary to press-fit the bearings and the motor end covers. The motor generally includes components such as the stator, rotor, casing and two end covers. The stator and rotor are fixed in the casing, and the two end covers are respectively arranged at both ends of the casing. The motor end cover and the motor casing are connected at the butt end. In order to meet the installation and tightening requirements and sealing, it is necessary to apply glue to the top of the motor casing and then fix the end cover and the casing through press-fitting and bolting.

[0003] In the prior art, since the installation of the motor and the end cover needs to be fastened by a motor end cover pressing mechanism, and the pressing mechanism is composed of a base, an end cover fixing seat, a lifting rod, a pressing plate and a support frame, when using the motor end cover pressing mechanism, it is necessary to contact the end of the motor with the end cover placed on the end cover fixing seat, and at the same time contact the motor and the end cover through the lifting rod and the pressing plate, and then fix the motor and the end cover through bolts, so that the use of the end cover pressing mechanism can be completed. However, when the end cover pressing mechanism is used, since the end cover fixing seat needs to match the shape of the end cover, the shape of the end cover fixing seat cannot be changed at will, and the motor models are various. Therefore, every time the end cover pressing mechanism presses different batches of motors and end covers, it is necessary to replace the end cover fixing seat corresponding to the motor model, which will cause the staff to spend extra time when replacing the end cover fixing seat, thereby delaying the work efficiency of the end cover pressing mechanism in pressing the motor and the end cover. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a motor end cover pressing mechanism to solve the problems raised in the above-mentioned background technology. The present invention can make the end cover fixing seat adjustable according to the size of the end cover placed on the motor of different models, thereby avoiding the time spent on replacing the end cover fixing seat when the motor and the end cover are pressed together.

[0005] In order to achieve the above object, the utility model is implemented by the following technical scheme: a motor end cover pressing mechanism, comprising a base, support plates are fixedly installed on both sides of the top of the base, a circular plate is fixedly connected to the center of the base, and a circular groove is opened in the center of the circular plate;

[0006] A connecting block is fixedly installed on the side surface of the support plate. The end of the connecting block is movably connected to a first arc plate. The top of the first arc plate is fixedly connected to a clamping plate. The back side of the clamping plate is fixedly connected to a receiving block. The surface of the receiving block is fixedly connected to an electric telescopic rod. A chute is formed on the top surface of the base. A slider is slidably connected inside the chute. The end of the top surface of the first arc plate is internally thread-connected with a bolt. A sliding rod is slidably connected inside the slider. A fixing block is fixedly connected to the center of the surface of the sliding rod.

[0007] Further, one connecting block is arranged on the side surface of each support plate. A groove matching the shape of the back side of the first arc plate is formed at the position where the connecting block contacts the first arc plate. Two symmetrically-positioned electric telescopic rods are in contact with the top of the connecting block. The ends of the two electric telescopic rods are in contact with the same support plate.

[0008] Further, two chutes are symmetrically formed on the top surface of the base. Two sliders are respectively arranged inside the two chutes. The position of the slider corresponds to the end position of the first arc plate. The bolt passes through the first arc plate and is in contact with the slider.

[0009] Further, a round block is fixedly arranged at the side end of the clamping plate. An electric push rod is fixedly connected inside the round block. The top end of the electric push rod is fixedly connected to a pressing block. The top of the pressing block is fixedly connected to a receiving plate. The bottom end of the inner wall of the receiving plate is fixedly connected to a limiting plate. A circular ring is fixedly installed at the center of the circular groove. Four convex blocks are fixedly arranged on the top of the circular ring.

[0010] Further, one round block is arranged at both ends of the same clamping plate. A groove is formed at the position where the clamping plate contacts the round block. One electric push rod is arranged inside each round block. The bottom of the receiving plate is connected to the ends of the electric push rods inside the round blocks at both ends of the same clamping plate.

[0011] Further, the circular ring fits on the inner wall of the circular groove. Four convex blocks are arranged at equal intervals on the top of the circular ring.

[0012] The beneficial effects of the present utility model are as follows: First, when the end cover is arranged on the surface of the circular plate, the electric telescopic rod is started. The electric telescopic rod pushes the clamping plate and the first arc plate to move. The slider in contact with the first arc plate moves together with the first arc plate. At the same time, the slider slides along the sliding rod. The centers of the first arc plate and the clamping plate are in contact with the surface of the end cover at the position of the circular plate. In this way, the base can adjust the size of the placed end cover according to different models of motors, thereby preventing the time consumed in replacing the base when the motor is pressed with the end cover.

[0013] Secondly, after the motor and the end cover are pressed together, the surface of the motor contacts the limiting plate at the center of the bearing plate. At the same time, the electric push rod is started. The electric push rod pushes the bearing plate and the motor to disengage from the corresponding position at the center of the circular plate. At the same time, the end of the end cover contacts the circular ring and the convex block at the center of the circular plate, thereby preventing the end cover from fitting with the circular plate. In this way, it is more convenient to remove the pressed motor and end cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , a circular block 7 is fixedly arranged at the side end of the clamping plate 402, an electric push rod 701 is fixedly connected inside the circular block 7, a pressing block 702 is fixedly connected to the top end of the electric push rod 701, a receiving plate 703 is fixedly connected to the top of the pressing block 702, a limiting plate 704 is fixedly connected to the bottom end of the inner wall of the receiving plate 703, a circular ring 8 is fixedly installed at the center of the circular groove 301, and a convex block 801 is fixedly arranged on the top of the circular ring 8.
