[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-5As shown, an end cover pressing device for motor assembly comprises a fixing seat 1, a first tooth comb plate 7, a second tooth comb plate 8 and a mounting plate 9, wherein the first tooth comb plate 7 is slidably connected with the second tooth comb plate 8, the upper end surface of the first tooth comb plate 7 away from the second tooth comb plate 8 is fixedly mounted with the mounting plate 9, the upper end surface of the second tooth comb plate 8 away from the first tooth comb plate 7 is fixedly mounted with the fixing seat 1, wherein a motor body 2 is arranged between the fixing seat 1 and the mounting plate 9, a limiting component is arranged at a position corresponding to the end of the motor body 2 on the fixing seat 1, a pressing component is connected at a position corresponding to the end of the motor body 2 on the mounting plate 9, and a positioning component is arranged at the end of the pressing component;

[0026] In the device, the first tooth comb plate 7 and the second tooth comb plate 8 are slidably connected. Before pressing the front end cover of the motor and the motor body 2, the user can adjust the first tooth comb plate 7 and the second tooth comb plate 8 according to the size of the motor body 2 to be processed. After the first tooth comb plate 7 and the second tooth comb plate 8 are adjusted according to the length of the motor body 2, the user can place the motor body 2 on the upper end surface of the first tooth comb plate 7 and the second tooth comb plate 8, and then fix the end of the rear end cover of the motor body 2 by the limiting component, and then press the front end cover onto the motor body 2 by the pressing component. When the front end cover is pressed onto the motor body 2, with the assistance of the alignment component, the installation position of the front end cover and the motor body 2 can be prevented from being tilted or misaligned.

[0027] like Figure 1 and Figure 3 As shown, the limit assembly includes two sets of limit clamps 6 rotatably connected to the fixed seat 1, and the limit assembly also includes a telescopic rod 3 arranged between the two sets of limit clamps 6, and one end of the telescopic rod 3 is fixedly connected to the inner wall of the fixed seat 1. In actual use, the two sets of limit clamps 6 can respectively clamp and fix the two sides of the end of the motor body 2, thereby preventing the pressing assembly from assembling the front end cover and the motor body 2.

[0028] like Figure 3As shown, a contact pad 17 is fixedly installed at the telescopic end of the telescopic rod 3, and a sliding ring 4 is slidably installed on the outer wall of the fixed end of the telescopic rod 3, a return spring 5 is arranged between the contact pad 17 and the sliding ring 4, and the two ends of the return spring 5 are fixedly connected to the contact pad 17 and the sliding ring 4 respectively. Before the front end cover of the motor body 2 is pressed, the user pushes the motor body 2 to move in the direction of the fixed seat 1, and the rear end cover of the motor body 2 squeezes the contact pad 17 to shorten the telescopic end of the telescopic rod 3. When the contact pad 17 is squeezed, the contact pad 17 synchronously squeezes the return spring 5, and the return spring 5 also synchronously squeezes the sliding ring 4. When the sliding ring 4 slides on the outer wall of the telescopic rod 3, the two sides of the sliding ring 4 contact with the ends of the two groups of limit clips 6. The cross-section of the limit clip 6 is L-shaped. When the short side end of the limit clip 6 is squeezed, the long sides of the two groups of limit clips 6 can squeeze and limit the outer wall of the motor body 2, and the end of the motor body 2 can be limited and fixed.

[0029] like Figure 3 and Figure 4 As shown, the pressing assembly includes an extension plate 16 fixedly connected to the end of the first tooth comb plate 7, and the upper end surface of the extension plate 16 is fixedly installed with a limit pile 12. The pressing assembly also includes a striker rod 10 slidably connected to the mounting plate 9, and the end of the striker rod 10 is fixedly installed with a slide bar 13 near the limit pile 12, and the slide bar 13 is slidably connected to the upper end of the limit pile 12, and the outer wall of the end of the slide bar 13 is rotatably connected with a connecting rod 15, and a rotatable turntable 14 is fixedly installed at a position corresponding to the other end of the connecting rod 15 on the upper end surface of the extension plate 16, and the connecting rod 15 is fixedly installed with a rotatable turntable 14. The other end of the rod 15 is rotatably connected to the edge outer wall of the turntable 14. In actual application, the rotation of the turntable 14 can drive the connecting rod 15 to rotate. Under the transmission action of the connecting rod 15, the sliding rod 13 can be pushed to slide back and forth in the groove opened at the upper end of the limit pile 12. In the process of reciprocating sliding of the sliding rod 13, the impact rod 10 can be pushed to reciprocate, so that the end of the impact rod 10 presses the front end cover onto the end of the motor body 2 during the reciprocating motion, completing the rapid assembly of the motor body 2 as a whole.

[0030] like Figure 5 As shown, the alignment component includes a sliding sleeve 11 slidably connected to the end of the impact rod 10, and a suction cup 18 is fixedly installed at the end of the sliding sleeve 11. Before pressing the front end cover of the motor body 2, the user can adsorb the front end cover through the suction cup 18 according to the installation position of the front end cover. The front end cover adsorbed on the suction cup 18 can always remain parallel to the end face of the motor body 2, thereby avoiding the front end cover from tilting or the installation position being misaligned during the pressing process.

[0031] like Figure 4As shown, the number of impact rods 10 is not less than three groups, and they are evenly distributed in a circular array on the mounting plate 9. Under the push of the sliding rod 13, the end of the impact rod 10 can press the front end cover of the motor body 2. When multiple groups of impact rods 10 are pressed on the front end cover, uniform force can be applied to the front end cover.

[0032] like Figure 5 As shown, a buffer pad 19 is fixedly installed at the end of the impact rod 10 located inside the sliding sleeve 11, and the buffer pad 19 is an elastic structure. The buffer pad 19 can play a buffering role when the end of the impact rod 10 contacts the suction cup 18.

[0033] The working principle of the utility model is as follows: when in use, the user places the motor body 2 on the upper surface of the combination of the first tooth comb plate 7 and the second tooth comb plate 8, wherein the first tooth comb plate 7 and the second tooth comb plate 8 are slidably connected, and the first tooth comb plate 7 and the second tooth comb plate 8 can be fixed after being adjusted according to the size and length of the motor body 2, then the rear end cover of the motor body 2 is abutted against the contact pad 17, and then the end cover of the motor body 2 is adsorbed and positioned by the alignment component, and then the user drives the turntable 14 to rotate, and under the action of the connecting rod 15, when the end of the connecting rod 15 pushes the sliding rod 13 to reciprocate, the sliding rod 13 Multiple groups of impact rods 10 can be pushed forward synchronously. When the multiple groups of impact rods 10 move forward, their ends hit the suction cup 18, and then hit the front end cover adsorbed on the suction cup 18. When the front end cover is hit, under the action of the suction cup 18, the front end cover can always maintain an installation position parallel to the main body of the motor body 2. Then, when multiple places on the front end cover are evenly hit, the front end cover can be pressed together with the motor body 2, thereby completing the assembly of the motor. During the installation of the front end cover, the limit assembly can fix the end where the rear end cover of the motor body 2 is located, and the limit assembly can be suitable for limiting the ends of motor bodies 2 of various sizes.
