Description

Technical Field

[0001] This utility model belongs to the field of motor assembly technology, and specifically relates to a clamping device for motor assembly. Background Technology

[0002] Motor assembly refers to the process of assembling the various components of a motor into a complete motor according to design requirements and technical specifications. This process usually includes the installation and fixing of key components such as stator, rotor shaft, end cover, and bearings to ensure that the motor can work efficiently and stably during operation. Currently, special motor assembly clamping devices are usually required when performing clamping operations.

[0003] Existing pressing devices typically use clamping mechanisms to fix relevant components, then place the rotor shaft in a predetermined position, and subsequently the die head of the pressing machine moves down to complete the pressing operation. Although this method can achieve basic pressing of the rotor shaft, some problems still exist in actual operation: During the pressing process, the die head directly contacts the rotor shaft and presses it into the motor component. Due to the lack of effective positioning of the rotor shaft, problems such as internal hole roughening, adhesion, or housing deformation can easily occur during the pressing process, thereby affecting the assembly quality and motor performance. Utility Model Content

[0004] In view of this, the present invention provides a clamping device for motor assembly, which can ensure the stability of the rotor shaft when it is pressed in through a limiting mechanism, and avoid quality problems such as inner hole roughening, adhesion, and housing deformation caused by its deviation.

[0005] To solve the above-mentioned technical problems, this utility model provides a clamping device for motor assembly, including a clamping machine and a rotating assembly mounted thereon. The rotating assembly is provided with a limiting mechanism, which includes multiple placement frames mounted on the rotating assembly. Each placement frame has multiple sliding holes, and a sliding rod is slidably connected in each sliding hole. A guide plate is provided at the upper end of the multiple sliding rods located on the same placement frame, and a guide hole is provided in the middle of each guide plate. That is, through the periodic indexing of the rotating disk and the synergistic effect of the guiding mechanism, continuous, high-precision positioning and stable clamping of the motor assembly are achieved, ensuring the stability of the rotor shaft when pressed into the motor housing, avoiding quality problems such as internal hole roughening, adhesion, and housing deformation caused by its deviation, significantly improving production efficiency and assembly quality, and ensuring the coaxiality of the rotor shaft and the parts to be clamped.

[0006] The limiting mechanism also includes an annular groove on the rotating component. An arc plate is provided on the table of the pressing machine. The arc plate is located in the annular groove. A moving rod is slidably connected in each sliding hole. The upper end of the moving rod is slidably connected to the sliding groove provided at the lower end of the sliding rod located in the same sliding hole, which plays a role in transmission.

[0007] The limiting mechanism also includes springs respectively set in the slide groove. The lower end of the spring is fixedly connected to the upper end of the vertically adjacent sliding rod, that is, to provide elastic support force.

[0008] The limiting mechanism also includes rotating balls connected to the lower end of the sliding rod, which reduces the coefficient of friction.

[0009] The rotating assembly includes a rotating disk rotatably connected to the press table, with the placement racks located on the rotating disk, and an annular groove located at the lower end of the rotating disk, providing rotational support for the auxiliary mechanisms thereon.

[0010] The rotating assembly also includes a motor located at the lower end of the press. The upper end of the motor's output shaft is fixedly connected to the lower end of the rotating disk, thus providing a drive source for the rotating disk and its auxiliary mechanisms.

[0011] The axis of the guide hole coincides with the axis of the mounting bracket it is placed on.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When the mounting frame containing the motor parts and rotor shaft is moved directly under the pressing die of the pressing machine, the pressing machine operates to press the rotor shaft into the motor parts. During this process, the guide hole of the guide plate accurately positions the rotor shaft to ensure the coaxiality of the rotor shaft and the part to be pressed. The sliding rod slides through the slide groove and the moving rod, compressing the spring to avoid collisions and ensure the stability of the rotor shaft when it is pressed in, thus preventing it from shifting and causing quality problems such as roughening of the inner hole, adhesion, and deformation of the machine casing.

[0014] 2. When motor assembly is required, the outermost mounting bracket is vertically aligned with the arc-shaped plate. At this time, the rotating ball at the lower end of the moving rod contacts the upper plane of the arc-shaped plate, causing the spring, moving rod, guide plate, and sliding rod to rise as a whole, thus providing space for the motor components. The motor components are then placed in the outermost mounting bracket, and the rotor shaft is inserted into the guide hole and aligned with the corresponding installation position of the motor component. Subsequently, the motor starts, and its output shaft rotates, causing the rotating disk and its multiple mounting brackets to rotate 90 degrees synchronously. During this process, the rotating ball slides along the surface of the arc-shaped plate and eventually disengages from it. At this point, the spring, moving rod, guide plate, and sliding rod move downwards and reset under gravity, waiting for the next mounting bracket to move. When the motor is vertically aligned with the curved plate, repeat the above placement process, placing the motor parts and rotor shaft in sequence. Repeat this process until the clamping operation is complete. Then, the motor rotates 90 degrees again, completing the clamping at the current station and simultaneously starting the next feeding station, achieving parallel assembly and feeding operations. When the clamped motor returns to its initial position, the ball bearing slides along the curved plate again. When it reaches its apex, the spring, moving rod, guide plate, and sliding rod lift upwards again, making it easy for the operator to remove the parts. Then, repeat the above placement process again. The entire process, through the periodic indexing of the rotating disc and the synergistic effect of the guiding mechanism, achieves continuous, high-precision positioning and stable clamping of the motor assembly, significantly improving production efficiency and assembly quality.

[0015] 3. The rotating ball reduces the coefficient of friction between the ball and the curved plate and the press table. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a clamping device for motor assembly, such as... Figure 1-4 The device includes a pressing machine 100 and a rotating assembly mounted thereon. The rotating assembly has a limiting mechanism, which includes multiple placement racks 200 mounted on the rotating assembly. Each placement rack 200 has multiple sliding holes, and a sliding rod 201 is slidably connected within each sliding hole. Guide plates 202 are provided at the upper ends of the multiple sliding rods 201 located on the same placement rack 200, and each guide plate 202 has a guide hole in its center. The limiting mechanism also includes an annular groove 203 mounted on the rotating assembly. The pressing machine 100... An arc-shaped plate 204 is provided on the table surface. The arc-shaped plate 204 is located on the outermost side and is located in the annular groove 203. A moving rod 205 is slidably connected in each sliding hole. The upper end of the moving rod 205 is slidably connected to the sliding groove provided at the lower end of the sliding rod 201 located in the same sliding hole. The limiting mechanism also includes springs 206 respectively provided in the sliding groove. The lower end of the springs 206 is fixedly connected to the upper end of the vertically adjacent sliding rod 201. The axis of the guide hole coincides with the axis of the placement frame 200 in which it is located.

[0023] When motor assembly is required, the outermost placement rack 200 is vertically aligned with the arc-shaped plate 204. At this time, the ball bearing 207 at the lower end of the moving rod 205 contacts the upper plane of the arc-shaped plate 204, causing the spring 206, moving rod 205, guide plate 202, and sliding rod 201 to rise upwards as a whole, thus providing space for the motor components. The motor components are then placed in the outermost placement rack 200, and the rotor shaft is inserted into the guide hole and aligned with the corresponding installation position of the motor component. Subsequently, multiple placement racks are installed... The placement rack 200 rotates 90 degrees synchronously. During this process, the rotating ball 207 slides along the surface of the arc plate 204 and eventually disengages from it. At this time, the spring 206, the moving rod 205, the guide plate 202, and the sliding rod 201 move downwards and reset under gravity. When the next placement rack 200 moves to be vertically aligned with the arc plate 204, the above placement process is repeated, and the motor accessories and rotor shaft are placed in sequence. This process is repeated until the placement rack 200 containing the motor accessories and rotor shaft moves to be directly under the pressing mold of the pressing machine 100. The pressing machine 100 then... The process involves pressing the rotor shaft into the motor components. During this process, the guide hole of the guide plate 202 precisely positions the rotor shaft, ensuring the coaxiality of the rotor shaft and the component to be pressed. The sliding rod 201 slides through the slide groove and the moving rod 205, compressing the spring 206 to avoid misalignment and ensure the stability of the rotor shaft during pressing, preventing quality problems such as inner hole roughening, adhesion, and housing deformation. Then, the multiple placement racks 200 rotate 90 degrees again, completing the pressing at the current station and simultaneously starting the next feeding station, thus realizing the loading... The parallel operation of material feeding and pressing involves the rotating ball 207 sliding along the arc plate 204 again when the motor returns to its initial position after pressing. When it reaches its apex, the spring 206, moving rod 205, guide plate 202, and sliding rod 201 are lifted upwards again to facilitate the operator's removal. The above placement process is then repeated. The entire process, through the periodic indexing of the rotating disk 300 and the coordinated action of the guiding mechanism, achieves continuous motor assembly, high-precision positioning, and stable pressing, significantly improving production efficiency and assembly quality.

[0024] like Figure 2-4 As shown, the limiting mechanism also includes rotating balls 207 that are rotatably connected to the lower end of the sliding rod 201.

[0025] Reduce its coefficient of friction with the curved plate 204 and the press machine 100 table surface.

[0026] like Figure 2-3 As shown, the rotating assembly includes a rotating disk 300 rotatably connected to the table of the press machine 100, and placement racks 200 are all located on the rotating disk 300. An annular groove 203 is located at the lower end of the rotating disk 300. The rotating assembly also includes a motor 301 disposed at the lower end of the press machine 100. The upper end of the output shaft of the motor 301 is fixedly connected to the lower end of the rotating disk 300.

[0027] When motor 301 starts, its output shaft rotates, causing the rotating disk 300 and its multiple placement racks 200 to rotate 90 degrees synchronously.

[0028] The working principle of the clamping device for motor assembly provided by this utility model is as follows: When the motor needs to be assembled, the outermost placement rack 200 is vertically aligned with the arc plate 204. At this time, the ball bearing 207 at the lower end of the moving rod 205 contacts the upper plane of the arc plate 204, thereby causing the spring 206, the moving rod 205, the guide plate 202, and the sliding rod 201 to be lifted upward as a whole, thus providing space for the motor parts to be placed. Then, the motor parts are placed in the outermost placement rack 200, and then the rotor shaft is inserted into the guide hole and engaged with the motor parts. The corresponding installation positions are then aligned. Motor 301 starts, and its output shaft rotates, causing the rotating disk 300 and its multiple placement racks 200 to rotate synchronously by 90 degrees. During this process, the ball bearing 207 slides along the surface of the arc-shaped plate 204 and eventually disengages from it. At this time, the spring 206, moving rod 205, guide plate 202, and sliding rod 201 move downwards and reset under gravity. When the next placement rack 200 moves to be vertically aligned with the arc-shaped plate 204, the above placement process is repeated, placing the motor components and rotor shaft sequentially. This process is repeated until the placement rack containing the motor components and rotor shaft is complete. When the mounting frame 200 moves directly under the pressing die of the pressing machine 100, the pressing machine 100 operates, pressing the rotor shaft into the motor components. During this process, the guide hole of the guide plate 202 precisely positions the rotor shaft, ensuring the coaxiality of the rotor shaft and the component to be pressed. The sliding rod 201 slides through the sliding groove and the moving rod 205, compressing the spring 206 to avoid collisions, ensuring the stability of the rotor shaft during pressing and preventing quality problems such as inner hole roughening, adhesion, and casing deformation caused by its deviation. Then, the motor 301 rotates ninety degrees again, completing the pressing at the current station and simultaneously pressing the rotor shaft into the motor components. The next material feeding station is started, realizing parallel operation of assembly and material feeding. When the motor that has been pressed returns to the initial position, the ball bearing 207 slides along the arc plate 204 again. When it moves to its apex, the spring 206, the moving rod 205, the guide plate 202 and the sliding rod 201 are lifted up again to facilitate the operator to take it out. Then the above placement process is repeated. The whole process realizes the continuous, high-precision positioning and stable pressing of motor assembly through the periodic indexing of the rotating disk 300 and the coordinated action of the guiding mechanism, which significantly improves production efficiency and assembly quality.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
