[0066] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0067] Figure 1 1 is a schematic diagram of the structure of an auxiliary device for preventing small parts from falling off a semi-automatic transmission housing according to an embodiment of the present invention. Figure 1 In the embodiment, the auxiliary device may include a protective plate 14, a connecting plate 16, a limiting assembly and a lifting assembly. Specifically, the connecting plate 16 may include an inclined plate and a flat plate.

[0068] The connecting plate 16 is arranged on the side of the protective plate, the lower end of the inclined plate is connected to the side wall of the protective plate 14, and the flat plate is connected to the upper end of the inclined plate and is parallel to the protective plate 14. The limiting assembly is arranged on the side of the flat plate away from the inclined plate, and is used to limit the height of the flat plate to drive the protective plate 14 to protect the hollow part of the gearbox housing. The lifting assembly is used to lift the connecting plate 16 to drive the protective plate 14 to return to the position to be protected.

[0069] During the assembly of the gearbox housing, the limit assembly adjusts and limits the height of the flat plate, and simultaneously adjusts and limits the height of the protective plate 14, so as to drive the protective plate 14 into the hollow position of the gearbox housing, and to block and protect the hollow position. Specifically, the shape of the protective plate 14 matches the shape of the hollow position of the gearbox housing, so as to achieve a completely sealed blockage with the hollow position. After the protective plate 14 protects the hollow position, the operator can assemble the gearbox housing. After the operator completes the assembly of the gearbox housing, the lifting assembly starts and lifts the connecting plate 16, and drives the protective plate 14 to rise synchronously through the connecting plate 16 and reset to the position to be protected, waiting for the assembly of the next gearbox housing. Specifically, the position to be protected is the initial position of the connecting plate 16.

[0070] In the production and assembly process of the traditional gearbox housing, many small screws and other parts need to be assembled manually due to the workpiece itself or the rhythm. However, such small parts are easy to fall into the hollow position of the gearbox housing and are not easy to be found, which can easily cause the gearbox to malfunction. In this embodiment of the present invention, the hollow position of the gearbox housing is blocked by the limit assembly and the protective plate 14, which can prevent small parts such as screws from falling into the gearbox housing, thereby preventing the gearbox from malfunctioning and effectively reducing the defective rate of the gearbox. In addition, the inclined plate can increase the distance between the flat plate and the gearbox housing, ensuring sufficient operating space for the assembler, thereby reducing the impact of the auxiliary device on the assembler's operation.

[0071] In this embodiment of the invention, Figures 3 to 7 As shown, the limiting assembly may include a support plate 7, a limiting seat 11, a clamping assembly and a guide assembly. Specifically, the limiting seat 11 may include a limiting hole 26 and a limiting groove 10.

[0072] The limit seat 11 is arranged on the side of the support plate 7 facing the flat plate, the bottom end of the limit seat 11 is provided with a limit hole 26, and the top end of the limit seat 11 is provided with a limit slot 10. The clamping assembly is arranged on the top of the flat plate, and is used to cooperate with the limit hole 26 or the limit slot 10 to fix the flat plate.

[0073] When the protective plate 14 needs to be driven to move to the hollow position of the gearbox housing, the driving clamping assembly is disengaged from the clamping with the top limit groove 10, and then the clamping assembly is clamped with the limit groove 10. When the clamping assembly is moved, it is guided by the guide assembly so that the clamping assembly can be smoothly moved to the clamping position of the limit groove 10 or the limit hole 26.

[0074] In this embodiment of the invention, Figure 3 , Figure 4 and Figure 5 As shown, the clamping assembly may include a clamping seat 19 , a sleeve 13 , a clamping rod 25 , a spring 24 , a driving opening 23 , a connecting column 12 and a pull rod 18 .

[0075] The clamping seat 19 is arranged on the top of the flat plate, the sleeve 13 is arranged on the side of the clamping seat 19 facing the limiting seat 11, and the open end of the sleeve 13 is in contact with the side wall of the limiting seat 11. The clamping rod 25 is arranged inside the sleeve 13, and one end of the clamping rod 25 is used to extend to the inside of the limiting hole 26 or the limiting groove 10 to limit and fix the flat plate. One end of the spring 24 is connected to the other end of the clamping rod 25, and the other end of the spring 24 is connected to the inner wall of the sleeve 13. The driving opening 23 is opened in the side wall of the sleeve 13, and the connecting column 12 movably passes through the driving opening 23, and one end of the connecting column 12 is connected to the side wall of the clamping rod 25. The pull rod 18 is arranged above the flat plate, and the end of the pull rod 18 is connected to the other end of the connecting column 12.

[0076] When it is necessary to drive the protective plate 14 to move to the hollow position of the gearbox, the operator pulls the pull rod 18 outward, drives the clamping rod 25 to move through the connecting column 12 and compresses the spring 24, drives the connecting rod 25 to move out of the limiting groove 10, and then the clamping seat 19 loses its limit. Under the action of gravity, the protective plate 14 falls to the hollow position of the gearbox housing, thereby achieving the blocking of the hollow position of the gearbox housing.

[0077] In this embodiment of the present invention, considering the convenience and stability of the operator pulling the pull rod 18, the shape of the pull rod 18 can be as follows: Figure 1 Specifically, Figure 1In the embodiment, the pull rod 18 may have an L-shape.

[0078] In this embodiment of the invention, Figure 1 and Figure 2 As shown, the guide assembly may include a slide rail 8 and a slide plate 9.

[0079] The slide rail 8 is arranged on the side wall of the support plate 7 close to the flat plate, the slide plate 9 is slidably connected to the slide rail 8, and the bottom end of the slide plate 9 is fixedly connected to the top of the flat plate.

[0080] When the connecting rod 25 moves out of the limiting groove 10 or the limiting hole 26, the clamping seat 19 loses its limitation, and the flat plate descends or rises under the action of gravity or the action of the lifting assembly, driving the slide plate 9 to slide along the slide rail 8, thereby improving the stability and reliability of the movement of the protective plate 14.

[0081] In this embodiment of the present invention, the number of the slide rails 8 can be various forms known to those skilled in the art, such as 1, 2, etc. However, in a preferred example of the present invention, considering the safety and reliability of the sliding of the slide plate 9, the number of the slide rails 8 can be 2. Specifically, the two slide rails 8 are arranged in parallel.

[0082] In this embodiment of the invention, Figure 1 and Figure 2 As shown, the guide assembly may further include a limit block 21 , a hydraulic buffer 20 and a stop pin 22 .

[0083] When the lifting assembly drives the slide plate 9 to move upward and reset, the stop pin 22 first contacts the hydraulic buffer 20, and the hydraulic buffer 20 buffers the slide plate 9 to prevent the slide plate 9 from having an excessive impact force that affects its service life. In addition, the limit block 21 can limit the position of the slide plate 9, which can accurately locate the slide plate 9 and prevent the slide plate 9 from derailing.

[0084] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the lifting assembly may include a cylinder bracket 6 , a lifting cylinder 3 and a lifting plate 1 .

[0085] The cylinder bracket 6 is arranged on the side wall of the support plate 7 facing the flat plate, the lifting cylinder 3 is arranged on the cylinder bracket 6, the lifting plate 1 is arranged below the lifting cylinder 3 and connected to the output end of the lifting cylinder 3, and the end of the lifting plate 1 extends to the bottom of the flat plate.

[0086] When it is necessary to drive the protective plate 14 to reset, the lifting cylinder 3 starts and drives the lifting plate 1 to rise. The lifting plate 1 gradually contacts the bottom of the flat plate and drives the flat plate to rise synchronously. The flat plate driving slide plate 9 rises steadily along the slide rail 8 until the corresponding clamping rod 25 enters the interior of the limit groove 10, thereby achieving the purpose of driving the protective plate 14 to reset.

[0087] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the lifting assembly may include a switch bracket 4, a first proximity switch 5, a second proximity switch 2 and a detection bracket 17. Specifically, the detection bracket may include an identification block.

[0088] The switch bracket 4 is arranged on the side wall of the lifting cylinder 3, the first proximity switch 5 is arranged on the top side wall of the switch bracket 4, and the second proximity switch 2 is arranged on the bottom side wall of the switch bracket 4. The detection bracket 17 is arranged on the top of the flat plate, and the top side wall of the detection bracket 17 is provided with an identification block that cooperates with the first proximity switch 5 or the second proximity switch 2 to start.

[0089] During the up and down movement of the protective plate 14, the identification block on the flat plate and the detection bracket 17 is driven to move synchronously. The first proximity switch 5 and the second proximity switch 2 can determine whether the protective plate 14 is in a blocked state or a reset state through the identification block, so as to realize the precise control of the position of the protective plate 14, thereby further improving the effectiveness of the protective plate 14 in blocking the gearbox housing.

[0090] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the auxiliary device may further include a baffle 15. Specifically, the baffle 15 is arranged on the top side wall of the protective plate 14. Specifically, the baffle 15 and the protective plate 14 form a storage box shape, which is convenient for collecting and processing small parts such as screws, and can prevent small parts such as screws from entering between the protective plate 14 and the hollow inner wall of the gearbox housing, making it inconvenient to take out.

[0091] In this embodiment of the present invention, the specific shape of the limiting groove 10 can be various forms known to those skilled in the art, such as square, angle, etc. However, in a preferred embodiment of the present invention, considering the ease of entry of the clamping rod 25 and the stability of the support of the clamping rod 25, the specific shape of the limiting groove 10 can be as follows: Figure 1 Specifically, Figure 1 In the embodiment, the limiting groove 10 may include a U-shape.

[0092] Through the above technical solution, the auxiliary device for preventing small parts from falling of the semi-automatic transmission housing provided by the present invention limits the height of the flat plate through the limit assembly, so that the protective plate 14 falls into the hollow part of the transmission housing, and the protective plate 14 can block and protect small parts, thereby preventing the occurrence of small parts falling due to misoperation during manual assembly of small parts, thereby improving the safety and reliability of the transmission housing assembly process. After the assembly of the transmission housing is completed, the lifting assembly can lift the protective plate 14 to reset it to wait for the assembly of the next transmission housing. In addition, the inclined plate can increase the distance between the flat plate and the transmission housing, ensuring sufficient operating space for the assembler, and reducing the impact of the auxiliary device on the assembler's operation.

[0093] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0094] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
