Description

Technical Field

[0001] The utility model relates to the field of stator assembly, in particular to a servo motor stator assembly mechanism. Background Art

[0002] The stator of the motor is the stationary part of the motor. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate current. The stator consists of three parts: the stator core, the stator winding and the base. The stator core is usually made of silicon steel sheets. A bearing chamber is provided in the middle of the core. Bearings need to be installed in the bearing chamber. When the bearings are installed, they need to be sleeved on the rotating shaft. If they are not aligned during installation, the installation will fail. However, in actual operation, different positioning seats need to be replaced for motor stators of different specifications, which is too cumbersome. Secondly, the overall equipment needs to remain relatively still when assembling the motor stator to prevent errors in the stator assembly, which may cause assembly failure or poor assembly quality. In order to solve the above problems, we propose a servo motor stator assembly mechanism. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In this embodiment, a mounting groove 4 is opened at the upper end of the assembly mechanism body 1, and a bidirectional screw rod 7 is rotatably connected to the inner side of the mounting groove 4. The outer sides of the bidirectional screw rod 7 are threadedly connected to the left clamping plate 5 and the right clamping plate 6. The rear end of the bidirectional screw rod 7 passes through the assembly mechanism body 1 and is fixedly connected to an eccentric wheel 8.

[0021] Specifically, by rotating the eccentric wheel 8 to drive the bidirectional screw rod 7 to rotate, the left clamping plate 5 and the right clamping plate 6 can be easily slid on the inner side of the installation groove 4.

[0022] In this embodiment, a driving wheel 9 is fixedly connected to the outer side of the bidirectional screw rod 7, a belt 10 is rotatably connected to the outer side of the driving wheel 9, the driving wheel 9 is rotatably connected to the driven wheel 11 through the belt 10, a rotating rod 12 is fixedly connected to the inner side of the driven wheel 11, the rotating rod 12 is rotatably connected to the assembly mechanism body 1, a gear 13 is fixedly connected to the outer side of the rotating rod 12, a rack 14 is meshed with the outer edge of the gear 13, and the lower end of the rack 14 is fixedly connected to the conical cylinder 18.

[0023] Specifically, through the cooperation of the driving wheel 9, the belt 10 and the driven wheel 11, the rotating rod 12 can easily drive the gear 13 to rotate, thereby driving the rack 14 and the conical cylinder 18 to move up and down.

[0024] In this embodiment, the front and rear ends of the rack 14 are fixedly connected to the limit rod 15, and the front and rear ends of the inner wall of the installation box 17 are provided with limit grooves 16, and the limit rod 15 is slidably connected to the installation box 17 through the limit grooves 16.

[0025] Specifically, the cooperation between the limiting rod 15 and the limiting groove 16 can facilitate the up and down movement of the rack 14 .

[0026] In this embodiment, two groups of round rods 19 are arranged on the outside of the conical cylinder 18, and two groups of pull rods 20 are fixedly connected to the outside of the two groups of round rods 19. The ends away from each other of the four groups of pull rods 20 are fixedly connected with abutment plates 21, which are adapted to the rollers 22.

[0027] Specifically, the cooperation between the round rod 19 and the pull rod 20 facilitates the contact or separation between the abutment plate 21 and the roller 22 .

[0028] In this embodiment, sliders 24 are fixedly connected to both sides of the two groups of round rods 19, and slide grooves 23 are opened on both sides of the assembly mechanism body 1.

[0030] It should be noted that the utility model is a servo motor stator assembly mechanism. The user places the motor stator to be assembled on the upper end of the placement plate 3. At this time, the eccentric wheel 8 is rotated. The rotation of the eccentric wheel 8 will drive the bidirectional screw rod 7 to rotate. The rotation of the bidirectional screw rod 7 will drive the left clamping plate 5 and the right clamping plate 6 to move in relative directions, thereby clamping the stator. The rotation of the bidirectional screw rod 7 will also drive the driving wheel 9 to rotate. The rotation of the driving wheel 9 will drive the belt 10 to rotate. The rotation of the belt 10 will drive the driven wheel 11 to rotate. The rotation of the driven wheel 11 will drive the rotating rod 12 to rotate. The rotation of the rotating rod 12 will drive the gear 13 to rotate. The rotation of the gear 13 will drive the rack 14 to rotate. The movement of the round rod 19 will drive the pull rod 20 to move, and the movement of the pull rod 20 will drive the abutment plate 21 to abut against the roller 22, thereby limiting the roller 22 and preventing the stator processing end 2 from being unstable during the stator assembly, which will cause the stator assembly quality to be unqualified. When the stator is assembled, the eccentric wheel 8 is rotated in the opposite direction to release the clamping of the left clamping plate 5 and the right clamping plate 6 on the motor stator, and the gear 13 drives the rack 14 to move upward. Through the cooperation of the spring 25 and the slider 24, the abutment plate 21 can release the limit on the roller 22, which is convenient for moving the assembly mechanism body 1, which is more practical.
