Description

Technical Field

[0001] This invention relates to the field of press-fitting equipment technology, and specifically to an automatic press-fitting equipment for motorcycle gear covers. Background Technology

[0002] Gear press fitting is a method of assembling gear bearings onto a shaft. Its principle is to compress the gear bearings with pressure, making them fit more tightly with the gears on the shaft.

[0003] For example, Chinese Patent CN220006681 U discloses a gear chamber cover press-fit assembly device, including a base plate on which bearing positioning seats and speed controller positioning seats are fixed; several guide rods fixed around the base plate, with compression springs sleeved on the outer side of the guide rods; a press-fit plate slidably connected to the outer side of the guide rods, with a positioning cavity formed on the press-fit plate, the contour of which matches the shape of the inner edge of the bottom of the gear chamber cover; and a top plate movably connected to the guide rods and positioned above the press-fit plate, with a press-fit head fixed to the top of the top plate. This assembly device has a simple structure and can quickly position the speed controller, bearing, and oil seal ring, allowing them to be press-fitted in one go. However, the pressing force and distance of the press-fit plate in this assembly structure cannot be controlled or adjusted. If the positioning of any component is misaligned, the component will be directly damaged during press-fitting.

[0004] Therefore, there is an urgent need to design an automatic pressing machine for motorcycle gear covers that can control and adjust the pressing force and distance of the pressing plate to improve the quality of the finished product. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide an automatic pressing equipment for motorcycle gear covers. During use, the pressing distance and force of the punch head can be controlled. During pressing, the limiting mechanism can protect the parts to be pressed, prevent accidental damage to the workpiece, improve the pressing efficiency of the workpiece and ensure the product yield.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic pressing device for motorcycle gear covers, comprising a frame, the frame being composed of support rods and a sealing plate, a control box installed inside the frame, a base plate installed at the top of the frame, and support rods and a top sealing plate further provided on the outer contour of the base plate. The base plate is provided with a pressing mechanism, a limiting mechanism, an adjusting mechanism, and a feeding mechanism. The limiting mechanism is installed in the pressing mechanism to perform limit detection on the pressing mechanism. The adjusting mechanism is located at both ends of the pressing mechanism to control the downward pressure and distance during pressing. The feeding mechanism is located at the front end of the pressing mechanism to feed the finished product. The workpiece is clamped and transferred after completion; the pressing mechanism includes two vertical support plates, with a pressure plate fixed horizontally at the upper end of the support plates. Three parallel upper fixing plates, a middle fixing plate and a lower fixing plate are arranged sequentially at the upper end of the pressure plates. Guide rods are vertically connected to both ends of the three fixing plates. The lower end of the guide rod is connected to the lower fixing plate and the upper end is connected to the top sealing plate located at the top of the frame. A positioning fixture is arranged at the center of the upper end of the lower fixing plate. A connecting bracket is arranged on the middle fixing plate. A punch is also arranged at the lower end of the middle fixing plate. A linear drive assembly is arranged at the upper end of the upper fixing plate and is fixedly connected to the top sealing plate. The lower end of the linear drive assembly is connected to the connecting bracket.

[0007] Furthermore, the limiting mechanism includes a limiting support rod mounted on the pressure plate. The lower end of the limiting support rod is screwed to the pressure plate, and the upper end is screwed to a top cap. A pressure sensor is installed inside the top cap. The overall length of the limiting mechanism is changed by the helical movement of the top cap and the limiting support rod.

[0008] Furthermore, the adjustment mechanism includes a support plate, a connecting plate, a linear drive assembly, an adjusting rod, and a connecting seat. The support plate is fixed on the base plate, the linear drive assembly is mounted on the support plate, the connecting plate is vertically mounted on one side of the support plate, and the support plate has an arc-shaped slot at its center. A connecting seat is installed in the slot, and the upper end of the connecting seat is fixed to the top sealing plate by the adjusting rod. The side of the connecting seat is connected to the pressing mechanism.

[0009] Furthermore, the feeding mechanism includes a fixed base, a rotary connector, a linear drive assembly, a clamping member, a material box, and a discharge slide. The fixed base, the discharge slide, and the material box are sequentially installed on the front section of the base plate. The rotary connector is installed on the fixed base, the linear drive assembly is fixed on the rotary connector, and the clamping member is installed on the linear drive assembly. The discharge slide is inclined towards the material box.

[0010] Furthermore, the pressing mechanism, limiting mechanism, adjusting mechanism, and unloading mechanism are all electrically connected to the control box.

[0011] Furthermore, the positioning fixture is also provided with a positioning bracket on its waist for mounting optical sensors to detect the pressing state.

[0012] Furthermore, locking casters are also provided at the four corners of the bottom of the frame.

[0013] Furthermore, the positioning bracket consists of a collar sleeved on the clamp and a support ring located on one side of the clamp connected to the collar.

[0014] The beneficial effects of the present invention are: 1) The present invention controls the linear drive component in the pressing mechanism to extend through the control box, which will drive the middle fixed plate to move downward. 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 pressing. Compared with the traditional pressing structure, the pressing stability is better, and it can ensure that it moves straight up and down without deviation when pressing, resulting in a high pressing yield.

[0015] 2) The present invention uses a limiting mechanism to ensure that the pressing mechanism is supported even when it continues to move downwards, and the installed pressure sensor can detect the pressure in time and transmit it to the control box to prevent excessive pressing force from damaging the workpiece.

[0016] 3) The present invention offsets the downward pressure at the pressing mechanism and controls the pressing distance by adjusting the linear drive component of the mechanism. Specifically, when the lower fixed plate and the middle fixed plate are close to each other during pressing, the adjusting mechanism can further control the downward pressure and distance during pressing, protect the workpiece from damage, and has a simple structure and is easy to use.

[0024] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments.

[0025] Example: Figure 1-6 As shown, an automatic pressing device for motorcycle gear covers according to the present invention includes a frame 1, which is composed of a support rod 2 and a sealing plate 3. A control box 4 is installed inside the frame 1. A base plate is installed on the top of the frame 1. The support rod 2 and the top sealing plate 5 are also provided on the outer contour of the base plate. A pressing mechanism 6, a limiting mechanism 7, an adjusting mechanism 8 and a feeding mechanism 9 are provided on the base 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 feeding 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 feeding mechanism 9 are all electrically connected to the control box 4.

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

[0027] The limiting mechanism 7 includes a limiting support rod 20 mounted on the pressure plate 11. The lower end of the limiting support rod 20 is screwed to the pressure plate 11, and the upper end is screwed to a top cap 21. A pressure sensor is installed inside the top cap 21. The overall length of the limiting mechanism 7 is changed by the helical 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 pressing, the position of the top cap 21 on the limiting support rod 20 is exactly the same as the distance between them. This ensures that even if the pressing mechanism 6 continues to move downward, it will be supported by the limiting mechanism 7, preventing excessive pressing force from damaging the workpiece. The installed pressure sensor can also detect the pressure in time and transmit it to the control box 4 to prevent excessive downward pressure.

[0028] The adjusting mechanism 8 includes a support plate 22, a connecting plate 23, a linear drive assembly 19, an adjusting rod 24, and a connecting seat 25. The support plate 22 is fixed on the base plate, the linear drive assembly 19 is mounted on the support plate 22, and the connecting plate 23 is vertically mounted on one side of the support plate 22. The support plate 22 has an arc-shaped slot in the center, and the connecting seat 25 is installed in the slot. The upper end of the connecting seat 25 is fixed to the top sealing plate 5 through the adjusting rod 24, and the side is connected to the pressing mechanism 6. The linear drive assembly 19 is driven to extend and retract through the control box 4 to change the distance between the linear drive assembly 19 and the connecting seat 25. The lifting linear drive assembly 19 can counteract the downward pressure at the pressing mechanism 6 and control the downward pressing distance. Specifically, when the lower fixed plate 14 and the middle fixed plate 13 are close to each other during 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 base 26, a rotary connector 27, a linear drive assembly 19, a clamping member 28, a material box 29, and a discharge slide 30. The fixed base 26, the discharge slide 30, and the material box 29 are sequentially installed on the front section of the base plate. The rotary connector 27 is installed on the fixed base 26. The linear drive assembly 19 is fixed on the rotary connector 27. The clamping member 28 is installed on the linear drive assembly 19. The discharge slide 30 is inclined towards the material box 29. The rotary connector 27, the linear drive assembly 19, and the clamping member 28 are controlled by the control box 4 to move the workpiece located at the pressing mechanism 6 into the discharge slide 30 and collect it into the material box 29.

[0030] The positioning fixture 16 is also provided with a positioning bracket 31 on its waist; the positioning bracket 31 consists of a collar sleeved on the fixture 16 and a support ring connected to the collar on one side of the fixture 16, which is used to install an optical sensor to detect the pressing state. The detected state can be linked with the control box 4 signal to facilitate control of the pressing or moving commands.

[0031] Locking casters are also provided at the four corners of the bottom of the frame 1, which can lock the movement or use status of the frame 1, facilitating transfer and transportation. During use, the pressing distance and force of the punch head can be controlled. During pressing, the limiting mechanism can protect the parts to be pressed, prevent accidental damage to the workpiece, improve the pressing efficiency of the workpiece and ensure the product yield. Moreover, the structure is simple and easy to use.

[0032] This invention controls the linear drive component in the pressing mechanism to extend through the control box, which drives the middle fixed plate to move downward. At the same time, the punch at the lower end moves closer to the positioning fixture on the lower fixed plate. When the workpiece is placed in place, the gradually approaching middle and lower fixed plates will squeeze the workpiece together to complete the pressing. Compared with the traditional pressing structure, the pressing stability is better, ensuring that it moves straight up and down without deviation during pressing, and the pressing yield is high.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
