Description

Technical Field

[0001] This invention mainly relates to the field of motor assembly, and specifically to a motor shaft retainer press-in device. Background Technology

[0002] During the assembly of the motor shaft and the front frame, a bearing needs to be installed between the shaft and the front frame. In order to lock the bearing in place, a retaining ring needs to be installed at the connection between the shaft and the bearing. This step is usually completed at the end of the motor production process. In this step, the retaining ring installed outside the shaft is an external retaining ring.

[0003] Currently, the production process of installing retaining rings on motor shafts mostly involves manual assembly. This requires workers to manually pick out the outer retaining rings from the material box on the assembly line, and then manually use retaining ring pliers to adjust the curvature of the outer retaining rings and assemble them onto the shaft. In some cases, the outer retaining rings are over-expanded, resulting in an increased assembly gap between them and the shaft, rendering them ineffective. In addition, the heavy workload of the assembly line production means that workers need to perform the installation operation of the outer retaining rings and shafts.

[0004] To address the process issues affecting product quality in the assembly steps of the external retaining ring and the rotating shaft, the inventors proposed a motor rotating shaft retaining ring pressing device. This device employs a semi-automatic assembly method to complete the feeding and assembly of the external retaining ring, reducing the probability of external retaining ring failure due to individual worker operation issues.

Example

[0047] Reference Figure 1-9 A motor shaft retainer pressing device includes a vibratory feeder and a conveyor belt 2, and also includes the following structure:

[0048] The base 4 has a PLC controller fixedly mounted on its exterior. The PLC controller is electrically connected to the conveyor belt 2. The top of the base 4 is movably connected to a frame 41. The top of the frame 41 is fixedly mounted with an electric push rod 42, which is electrically connected to the PLC controller.

[0049] Two mounting brackets 5 are provided, and a slide block 6 is movably connected to the left side of the mounting bracket 5. The front and rear ends of the slide block 6 are both fixed with inclined guide rails 7.

[0050] The crank 8 has an internal spline 81 fixed at the top of its front end and an extension claw 82 fixed at the bottom of its rear end.

[0051] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a slide rail 3 is fixed on the left side of the conveyor belt 2, and an RFID reader is fixed on the inner side of the conveyor belt 2. The RFID reader faces the bottom of the extension claw 82 located above the conveyor belt 2. The identification part of the RFID reader is arranged close to the top belt of the conveyor belt 2. The RFID reader is connected to the PLC controller. The front end of the slide rail 3 is higher than its rear end. A mold 31 is slidably connected to the top of the slide rail 3. An RFID tag is fixed to the bottom of the mold 31. At least three connecting rods 32 are movably connected to the bottom of the mold 31. A return spring 33 and a clamping plate 34 are fixed to the middle and top of the connecting rods 32, respectively. The bottom of the return spring 33 is fixedly connected to the bottom of the mold 31.

[0052] The conveyor belt 2 transports the mold 31. During the operation of this equipment, at least one worker needs to be assigned to each of the feeding and discharging directions of the conveyor belt 2. In the feeding direction, the worker places the motor inside the mold 31. The return spring 33 and the connecting rod 32 work together to clamp and position the motor inside the mold 31 with the clamping plate 34. In the discharging direction, the worker removes the motor from the mold 31 and places the empty mold 31 on the slide rail 3 to slide back to the feeding direction of the conveyor belt 2.

[0053] The RFID reader is located below the top belt of the conveyor belt 2. When the conveyor belt 2 conveys the mold 31 past the RFID reader, the RFID reader reads the RFID tag. The PLC controller works with the conveyor belt 2 to pause the conveying of the mold 31, preparing for the assembly of the outer retaining spring.

[0054] The design of the slide 3 makes it convenient for workers to return the mold 31 from the discharge direction of the conveyor belt 2 to the feed direction of the conveyor belt 2.

[0055] In this embodiment, as Figure 4 and Figure 5 As shown, a toothed ring 4a is fixed on the top of the base 4, and the top of the base 4 passes through the middle of the bottom end of the frame 41.

[0056] The base 4 is used for mounting support and motion guidance of the frame 41.

[0057] In this embodiment, as Figure 5 As shown, a drive motor 41a is fixed on the left side of the frame 41. The drive motor 41a is electrically connected to the PLC controller. A spur gear 41b is fixed on the output end of the drive motor 41a. The right side of the spur gear 41b meshes with the left side of the gear ring 4a.

[0058] The PLC controller works in conjunction with the drive motor 41a. The drive motor 41a changes the rotation design of the frame 41 on the base 4 through the flat gear 41b and the gear ring 4a. The electric push rod 42 on the frame 41 changes the working height of the mounting brackets 5 on its left and right sides.

[0059] In this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the two mounting brackets 5 are fixedly connected to the top left and right sides of the electric push rod 42 on opposite sides. A slide rod 51 is fixedly provided at the left end of the mounting bracket 5. The outer side of the slide rod 51 is movably connected to the inner side of the left end of the slide block 6. A lead screw 52 is movably connected to the middle of the mounting bracket 5. The outer side of the lead screw 52 is threadedly connected to the right end of the slide block 6. An adjusting motor 53 is fixedly provided at the bottom of the lead screw 52. The adjusting motor 53 is electrically connected to the PLC controller. The outer side of the adjusting motor 53 is fixedly connected to the bottom of the mounting bracket 5. Auxiliary rods 54 are fixedly provided on the front and rear sides of the bottom of the mounting bracket 5.

[0060] Adjust the motor 53 and lead screw 52 to change the working position of the slide block 6 outside the slide rod 51, and complete the adjustment of the working height of the inclined guide rail 7 outside the mounting base.

[0061] In this embodiment, as Figure 1 , Figure 4 , Figure 6 and Figure 8 As shown, a positioning pin 71 is slidably connected to the middle of the inclined guide rail 7, and a positioning seat 72 is fixed at the bottom of the positioning pin 71. The inner side of the right end of the positioning seat 72 is slidably connected to the outer side of the auxiliary rod 54. An external spline 73 is fixed at the inner side of the bottom of the left end of the positioning seat 72, and the external spline 73 cooperates with the internal spline 81.

[0062] The inclined guide rail 7 changes the working position of the positioning seat 72 on the auxiliary rod 54 through the positioning pin 71, and completes the working distance adjustment of the two extension claws 82. The cooperation between the external spline 73 and the internal spline 81 makes it convenient for the user to change the specific installation position of the crank 8 at the bottom of the positioning seat 72, and completes the pre-adjustment of the working distance of the two extension claws 82, which is compatible with external or internal snap rings of different specifications and sizes.

[0063] In this embodiment, as Figure 1 , Figure 4 , Figure 6 and Figure 8 As shown, a guide groove is fixed in the middle of the inclined guide rail 7, the inclined guide rail 7 is symmetrically arranged about the front and rear sides of the middle of the slide block 6, and a structural stabilizing frame is fixed on the outer side of the inclined guide rail 7.

[0064] The inclined guide rail 7 works in conjunction with the auxiliary rod 54 to change the working distance of the positioning seat 72.

[0065] In this embodiment, as Figure 1 , Figure 4 and Figure 6 As shown, a limiting spring 9 is fixedly provided at the bottom of the front end of the crank 8, and a limiting bolt 91 is fixedly provided at the bottom of the limiting spring 9. The outer side of the limiting bolt 91 is sleeved with the middle of the front end of the crank 8. The top of the limiting bolt 91 passes through the bottom left end to the top left end of the positioning seat 72. The top of the limiting bolt 91 is threadedly connected to a limiting cap 92. The bottom of the limiting cap 92 abuts against the top of the positioning seat 72.

[0066] The cooperation between the limiting spring 9 and the limiting bolt 91 facilitates the assembly and production of external snap rings of different specifications. When the crank 8 is pressed down toward the bottom of the limiting bolt 91, the limiting spring 9 is compressed, contacting the connection between the inner spline 81 and the outer spline 73. At this time, the crank 8 is rotated outside the limiting bolt 91, releasing the crank 8 through the cooperation of the inner spline 81 and the outer spline 73, completing the positioning and installation of the crank 8 on the positioning seat 72, realizing the pre-adjustment of the working distance of the two extension claws 82, and adapting to external snap rings or inner snap rings of different specifications.

[0067] In this embodiment:

[0068] The RFID reader is located below the top belt of the conveyor belt 2. When the conveyor belt 2 conveys the mold 31 past the RFID reader, the RFID reader reads the RFID tag. The PLC controller works with the conveyor belt 2 to pause the conveying of the mold 31 and prepare for the assembly of the outer retaining spring. The PLC controller works with the drive motor 41a to complete the rotation design of the frame 41 on the base 4. The electric push rod 42 on the frame 41 changes the working height of the mounting brackets 5 on its left and right sides.

[0069] Adjusting the motor 53 and lead screw 52 changes the working position of the slide block 6 outside the slide rod 51, completing the adjustment of the working height of the inclined guide rail 7 outside the mounting base. The inclined guide rail 7 changes the working position of the positioning seat 72 on the auxiliary rod 54 through the positioning pin 71, completing the adjustment of the working distance of the two extension claws 82. The cooperation between the external spline 73 and the internal spline 81 allows the user to change the specific installation position of the crank 8 at the bottom of the positioning seat 72, completing the pre-adjustment of the working distance of the two extension claws 82, and adapting to external or internal snap rings of different specifications and sizes.

[0070] At this time, the extended claw 82 towards the vibratory feeder 1 grabs the outer retaining ring, and the extended claw 82 towards the conveyor belt 2 assembles the outer retaining ring onto the motor shaft. The worker in the discharge direction takes the motor with the outer retaining ring assembled from the mold 31, and at the same time places the empty mold 31 on the slide 3 and slides it back to the feeding direction of the conveyor belt 2.

[0071] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
