Description

Technical Field

[0001] This utility model relates to the field of motor equipment technology, and in particular to a snap ring mounting mechanism. Background Technology

[0002] The motor includes a housing, an electronic component housed within the housing, and a rotor located within the stator. The rotor is connected to a shaft, and at least one end of the housing is connected to a retaining circlip. The shaft passes through the retaining circlip. In traditional motor assembly, calipers are used to pry open the retaining circlip for assembly. However, some motors require the product to be installed first before the retaining circlip is assembled. This results in limited space during subsequent retaining circlip assembly. When assembling the retaining circlip on a shaft with limited installation space, the calipers obviously cannot meet the assembly requirements. Therefore, a retaining circlip mounting mechanism is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a snap ring mounting mechanism to solve the problem of snap ring assembly on motors in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A snap ring mounting mechanism, comprising:

[0006] A transplanting frame, on which an upper transplanting platform that can be raised and lowered is connected, and a lower transplanting module is provided on the lower side of the transplanting frame;

[0007] The lower transplanting module includes a lower transplanting platform located on the lower side of the transplanting machine frame. The lower transplanting platform is equipped with a product platform and a retaining spring platform. The retaining spring platform is equipped with a liftable pusher platform. The pusher platform is equipped with a tensioning claw, which extends out of the pusher platform. The bottom of the upper transplanting platform is equipped with a retaining spring column. The pusher platform pushes the retaining spring on the tensioning claw into the retaining spring column. The upper transplanting platform is equipped with a retaining spring pushing cylinder, which pushes the retaining spring into the product in the product platform.

[0008] To achieve the above technical solution, a transplanting frame is set up to support the transplanting machine. The lower transplanting module then assembles the retaining ring on the motor shaft. The product motor is placed on the product platform, and the retaining ring is first placed on the tensioning claw. The lower transplanting platform moves horizontally, causing the tensioning claw to move to the underside of the retaining ring column. The tensioning claw then expands the retaining ring, and the pusher pushes the retaining ring from the tensioning claw into the retaining ring column. The lower transplanting platform then moves horizontally, causing the product platform to move to the underside of the retaining ring column. Finally, the spring-push-in cylinder pushes the retaining ring into the product motor within the product platform, thus completing the retaining ring assembly. The retaining ring column can penetrate deep into the product, thus solving the problem of traditional clamps being unable to reach the motor shaft due to limited working space.

[0009] In one embodiment of the present invention, a tensioning cylinder is provided inside the snap ring platform, the tensioning claw is located at the movable end of the tensioning cylinder, and the tensioning claw is circumferentially fitted with the pusher table.

[0010] To achieve the above technical solution, a tensioning cylinder is set up, which drives the tensioning claw to open the retaining spring. The gap between the tensioning claw and the pusher table in the circumferential direction can provide sufficient opening space for the tensioning claw.

[0011] In one embodiment of this utility model, the lower side of the snap ring platform and the lower transplanting platform are fitted at an interval.

[0012] The above technical solution involves a spaced fit between the lower side of the snap ring platform and the lower transplanting platform, which provides ample assembly space for the lower side of the snap ring platform and facilitates the installation of the tensioning cylinder's drive components.

[0013] In one embodiment of the present invention, a snap ring upper push cylinder is provided on the lower side of the snap ring platform, and the pusher platform is located at the movable end of the snap ring upper push cylinder.

[0014] To achieve the above technical solution, a spring-loaded cylinder is set up to drive the pusher platform to move up and down, thereby pushing the spring on the tensioning claw into the spring column. A guide column is set at the movable end of the spring-loaded cylinder. The guide column passes through the spring platform and is connected to the pusher platform, which can guide the lifting and lowering movement of the pusher platform and improve the stability of the lifting and lowering movement of the pusher platform.

[0015] In one embodiment of the present invention, when the pusher pushes the retaining ring on the tensioning claw into the retaining ring post, the inner diameter of the retaining ring supported by the tensioning claw is larger than the outer diameter of the retaining ring post.

[0016] To achieve the above technical solution, in order to better enable the retaining ring to be pushed into the retaining ring post, the inner diameter of the tensioning claw supporting the retaining ring is larger than the outer diameter of the retaining ring post.

[0017] In one embodiment of the present invention, a ramp is provided on the inner wall of the bottom of the snap ring column.

[0018] To achieve the above technical solution, the inclined platform facilitates the connection and compatibility between the snap ring post and the motor shaft, thereby better ensuring the stability of the snap ring assembled on the motor shaft.

[0019] In one embodiment of the present invention, a positioning pin is provided on the lower side of the upper transplanting platform, and a positioning guide sleeve is provided inside the snap ring platform, with the positioning pin and the positioning guide sleeve slidingly engaged.

[0020] The above technical solution can be achieved by setting a sliding fit between the positioning pin and the positioning guide sleeve, which can improve the stability of the lifting and lowering movement of the upper transplanting platform.

[0021] In one embodiment of the present invention, a retaining ring push-in seat is provided on the lower side of the upper transplanting platform. The retaining ring push-in seat is located at the movable end of the retaining ring push-in cylinder, and the retaining ring column and the retaining ring push-in seat are in sliding fit.

[0022] To achieve the above technical solution, by setting up a circlip-pushing cylinder and cooperating with the circlip-pushing seat, a stable pushing of the circlip on the circlip column can be achieved.

[0023] In one embodiment of this utility model, a height measuring instrument is provided on the side of the transplanter frame away from the upper transplanting platform.

[0024] To achieve the above technical solution, a height measuring instrument is used to detect the position of the retaining ring pressed into the motor shaft, thereby determining the product qualification rate.

[0025] As described above, the snap ring mounting mechanism of this utility model has the following beneficial effects: by setting up a transplanting frame to support the transplanting frame, and cooperating with the lower transplanting module to realize the assembly of the snap ring on the motor shaft, the product motor is placed on the product platform, the snap ring is first placed on the tensioning claw, the lower transplanting platform moves horizontally to move the tensioning claw to the lower side of the snap ring column, then the tensioning claw opens the snap ring, the pusher pushes the snap ring on the tensioning claw into the snap ring column, then the lower transplanting platform moves horizontally to move the product platform to the lower side of the snap ring column, and then the spring pusher cylinder pushes the snap ring into the product motor in the product platform, thereby completing the assembly of the snap ring. The snap ring column can penetrate deep into the product, thereby solving the problem that traditional clamps cannot reach the motor shaft due to limited working space. Attached Figure Description

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please see Figures 1 to 4 This utility model provides a snap ring mounting mechanism, including a transplanting frame 1 with a liftable upper transplanting platform 2 connected to it. A lower transplanting module is provided on the lower side of the transplanting frame 1. The lower transplanting module includes a lower transplanting platform 3 located on the lower side of the transplanting frame 1. A product platform 4 and a snap ring platform 5 are provided on the lower transplanting platform 3. A liftable pusher 6 is provided on the snap ring platform 5. A tensioning claw 7 is provided inside the pusher 6. The tensioning claw 7 extends out of the pusher 6. A snap ring column 8 is provided at the bottom of the upper transplanting platform 2. The pusher 6 pushes the snap ring on the tensioning claw 7 into the snap ring column 8. A snap ring pushing cylinder 9 is provided on the upper transplanting platform 2. The snap ring pushing cylinder 9 pushes the snap ring into the product in the product platform 4.

[0034] By setting up a transplanting frame 1 to support the transplanting machine 1, and cooperating with the lower transplanting module to assemble the retaining ring on the motor shaft, the product motor is placed on the product platform 4, and the retaining ring is first placed on the tensioning claw 7. The lower transplanting platform 3 moves horizontally to move the tensioning claw 7 to the lower side of the retaining ring column 8. Then the tensioning claw 7 opens the retaining ring, and the pusher 6 pushes the retaining ring on the tensioning claw 7 into the retaining ring column 8. Then the lower transplanting platform 3 moves horizontally to move the product platform 4 to the lower side of the retaining ring column 8, and then the spring pusher cylinder pushes the retaining ring into the product motor inside the product platform 4, thus completing the assembly of the retaining ring. The retaining ring column 8 can penetrate deep into the product, thus solving the problem that traditional clamps cannot reach the motor shaft due to limited working space.

[0035] The snap ring platform 5 is equipped with a tensioning cylinder 10, and the tensioning claw 7 is located at the movable end of the tensioning cylinder 10. Furthermore, the tensioning claw 7 is circumferentially fitted with the pusher table 6. By setting the tensioning cylinder 10, the tensioning claw 7 is driven to open the snap ring. The circumferential fit between the tensioning claw 7 and the pusher table 6 provides sufficient opening space for the tensioning claw 7.

[0036] The lower side of the snap ring platform 5 is spaced apart from the lower transplanting platform 3. This spaced-apart fit provides sufficient assembly space for the lower side of the snap ring platform 5, making the installation of the drive component of the tensioning cylinder 10 convenient.

[0037] A snap ring upper release cylinder 11 is provided on the lower side of the snap ring platform 5. The pusher platform 6 is located at the movable end of the snap ring upper release cylinder 11. By setting the snap ring upper release cylinder 11, the pusher platform 6 is driven to move up and down, thereby pushing the snap ring on the tensioning claw 7 into the snap ring column 8. A guide column is set at the movable end of the snap ring upper release cylinder 11. The guide column passes through the snap ring platform 5 and is connected to the pusher platform 6. It can guide the up and down movement of the pusher platform 6 and improve the stability of the up and down movement of the pusher platform 6.

[0038] When the tensioning claw 7 pushes the retaining ring onto the retaining ring post 8 on the pusher platform 6, the inner diameter of the retaining ring supported by the tensioning claw 7 is larger than the outer diameter of the retaining ring post 8. In order to better enable the retaining ring to be pushed onto the retaining ring post 8, the inner diameter of the retaining ring supported by the tensioning claw 7 is larger than the outer diameter of the retaining ring post 8.

[0039] An inclined platform 12 is provided on the inner wall of the bottom of the snap ring column 8. The inclined platform 12 facilitates the connection and adaptation between the snap ring column 8 and the motor shaft, thereby better ensuring the stability of the snap ring assembled on the motor shaft.

[0040] A positioning pin 13 is provided on the lower side of the upper transplanting platform 2, and a positioning guide sleeve 14 is provided inside the snap ring platform 5. The positioning pin 13 and the positioning guide sleeve 14 slide together. By setting the positioning pin 13 and the positioning guide sleeve 14 to slide together, the stability of the upper transplanting platform 2 during the lifting and lowering process can be improved.

[0041] A retaining ring push-in seat 15 is provided on the lower side of the upper transplanting platform 2. A push-in drive component is provided inside the upper transplanting platform 2. The retaining ring push-in seat 15 is located at the movable end of the push-in drive component. The retaining ring column 8 and the retaining ring push-in seat 15 are slidably engaged. By setting the push-in drive component and cooperating with the retaining ring push-in seat 15, the retaining ring on the retaining ring column 8 can be stably pushed.

[0042] A height measuring instrument 16 is installed on the side of the transplanter frame 1 away from the upper transplanting platform 2. The height measuring instrument 16 is used to detect the position of the retaining ring pressed into the motor shaft, thereby determining the product qualification rate.

[0043] This invention utilizes a transplanting frame to support the transplanting machine, and in conjunction with the lower transplanting module, assembles the retaining spring on the motor shaft. The product motor is placed on the product platform, and the retaining spring is first placed on the tensioning claw. The lower transplanting platform moves horizontally, causing the tensioning claw to move to the underside of the retaining spring's column. The tensioning claw then expands the retaining spring, and the pusher pushes the retaining spring from the tensioning claw into the retaining spring's column. The lower transplanting platform then moves horizontally, moving the product platform to the underside of the retaining spring's column. Finally, a spring-push cylinder pushes the retaining spring into the product motor within the product platform, thus completing the retaining spring assembly. The retaining spring's column can penetrate deeply into the product, solving the problem of traditional clamps being unable to reach the motor shaft due to limited working space.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
