The assembly device has a simple structure and can quickly position the speed regulator, bearing and oil seal ring, so that they can be press-fitted at one time. The assembly device has a simple structure and can quickly position the speed regulator, bearing and oil seal ring, so that they can be press-fitted at one time. However, the force and distance of the press-fit plate of this assembly structure cannot be controlled and adjusted. Once the positioning of each component is offset, the components will be directly damaged during press-fitting.

DETAILED DESCRIPTION

[0024] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example: Figure 1-6 As shown, an automatic pressing device for a motorcycle gear cover of the present invention comprises a frame 1, which is composed of a support rod 2 and a sealing plate 3. A control box 4 is installed in the frame 1, a bottom plate is installed on the top of the frame 1, and a support rod 2 and a top sealing plate 5 are also arranged on the outer contour of the bottom plate. A pressing mechanism 6, a limiting mechanism 7, an adjusting mechanism 8 and a blanking mechanism 9 are arranged on the bottom plate. The limiting mechanism 7 is installed in the pressing mechanism 6 to perform limit detection on the pressing mechanism 6. The adjusting mechanism 8 is located at the left and right ends of the pressing mechanism 6 to control the downward pressure and distance during pressing. The blanking mechanism 9 is located at the front end of the pressing mechanism 6 to clamp and transfer the workpiece after pressing. The pressing mechanism 6, the limiting mechanism 7, the adjusting mechanism 8 and the blanking mechanism 9 are all electrically connected to the control box 4.

[0026] The pressing mechanism 6 includes two vertical support plates 10, and a pressing plate 11 is transversely fixed on the upper end of the support plate 10. Three parallel upper fixed plates 12, a middle fixed plate 13 and a lower fixed plate 14 are arranged in sequence on the upper end of the pressing plate 11. Guide rods 15 are vertically connected to the left and right ends of the three fixed plates. The lower end of the guide rod 15 is connected to the lower fixed plate 14, and the upper end is connected to the top sealing plate 5 located at the top of the frame 1. A positioning fixture 16 is arranged at the center of the upper end of the lower fixed plate 14, a connecting seat 17 is arranged on the middle fixed plate 13, and a punch 18 is also arranged at the lower end of the middle fixed plate 13. A linear drive component 19 fixedly connected to the top sealing plate 5 is arranged on the upper end of the upper fixed plate 12, and the lower end of the linear drive component 19 is connected to the connecting seat 17. The upper fixing plate 12 and the lower fixing plate 14 on the guide rod 15 are fixed, and the middle fixing plate 13 is slidably connected along the guide rod 15. The linear drive assembly 19 is extended by the control box 4 to drive the middle fixing plate 13 to move downward. At the same time, the punch 18 at the lower end will approach the positioning fixture 16 on the lower fixing plate 14. When the workpiece is placed in place, the gradually approaching middle fixing plate 13 and lower fixing plate 14 will squeeze the workpiece together to complete the press fitting; conversely, when the linear drive assembly 19 is retracted, the distance between the middle fixing plate 13 and the lower fixing plate 14 increases, and gradually returns to its original position.

[0027] The limiting mechanism 7 includes a limiting support rod 20 installed on the pressure plate 11. The lower end of the limiting support rod 20 is screwed and fixed to the pressure plate 11, and the upper end is screwed with a top cap 21. A pressure sensor is installed in the top cap 21. The overall length of the limiting mechanism 7 is changed by the spiral movement of the top cap 21 and the limiting support rod 20. Specifically, when the lower fixed plate 14 and the middle fixed plate 13 are close to each other for press-fitting, the position of the top cap 21 on the limiting support rod 20 is exactly the same as the distance between the two, so that even if the press-fitting mechanism 6 continues to move downward, it will be supported by the limiting mechanism 7 to prevent the press-fitting force from being too large and damaging the workpiece. The installed pressure sensor can also detect the pressure size and transmit it to the control box 4 in time to prevent excessive downward pressure.

[0028] The adjusting mechanism 8 comprises a supporting seat plate 22, a connecting plate 23, a linear drive component 19, an adjusting rod 24 and a connecting seat 25. The supporting seat plate 22 is fixed on the bottom plate, the linear drive component 19 is installed on the supporting seat plate 22, the connecting plate 23 is vertically installed on one side of the supporting seat plate 22, and a circular arc slot is opened in the center of the supporting seat plate 22, a connecting seat 25 is arranged in the slot, the upper end of the connecting seat 25 is fixed to the top sealing plate 5 by the adjusting rod 24, and the side is connected to the pressing mechanism 6. The linear drive component 19 is driven to extend and retract by the control box 4 to change the distance with the connecting seat 25. The downward pressure at the pressing mechanism 6 can be offset by the lifted linear drive component 19, and the downward pressure distance can be controlled. Specifically, when the lower fixed plate 14 and the middle fixed plate 13 are close to pressing, the adjusting mechanism 8 can further control the downward pressure and distance during pressing to protect the workpiece from damage.

[0029] The unloading mechanism 9 includes a fixed seat 26, a rotating connection 27, a linear drive component 19, a clamping member 28, a material box 29 and a discharge chute 30. The fixed seat 26, the discharge chute 30 and the material box 29 are sequentially installed on the front section of the bottom plate. The rotating connection 27 is installed on the fixed seat 26, the linear drive component 19 is fixed on the rotating connection 27, and the clamping member 28 is installed on the linear drive component 19, wherein the discharge chute 30 is inclined toward the direction of the material box 29. The rotating connection 27, the linear drive component 19 and the clamping member 28 are controlled by connecting to the control box 4 to operate, so that the clamping member 28 clamps the workpiece located at the pressing mechanism 6 and moves it to the discharge chute 30 and collects it in the material box 29.

[0030] A positioning bracket 31 is also provided at the waist of the positioning fixture 16; the positioning bracket 31 is composed of a ring mounted on the fixture 16 and a support ring connected to the ring and located on one side of the fixture 16, and is used to install an optical sensor to detect the pressing state. The detected state can be linked with the signal of the control box 4 to facilitate the control of the downward or upward movement command.

[0031] Locking universal wheels are also provided at the four corners of the bottom of the frame 1, which can lock the moving or use state of the frame 1 for easy transfer and transportation. The pressing distance and force of the punch head can be controlled during use, and the limit mechanism can be used to protect the parts to be pressed during press-fitting, preventing accidental damage to the workpiece, improving the press-fitting efficiency of the workpiece and ensuring the product yield, and the structure is simple and easy to use.

[0032] The present invention controls the linear drive component in the press-fitting mechanism to extend through a control box, which will drive the middle fixed plate to move downward, and at the same time, the punch at the lower end will approach the positioning fixture on the lower fixed plate. When the workpiece is placed in place, the gradually approaching middle fixed plate and lower fixed plate will squeeze the workpiece together to complete the press-fitting. Compared with the traditional press-fitting structure, the press-fitting stability is better, and it can ensure that the press goes straight up and down without deviation when pressing down, and the press-fitting yield is high.

Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
