Description

Technical Field

[0001] This utility model relates to the technical field of automotive steering gear assembly equipment, and in particular to a sealing ring oiling mechanism and a sensor cover assembly device. Background Technology

[0002] The sensor cover is an essential component of a car steering system, which is composed of various parts. Therefore, steering system assembly requires the use of multiple assembly devices for different components. Applying lubricant to the sealing rings of the sensor cover is a crucial step in the assembly process. However, existing sealing ring lubrication mechanisms only work for circular sealing rings, while sensor covers contain non-circular sealing rings, such as elliptical ones. Automatic lubrication of these non-circular sealing rings typically requires planning the path of the lubrication head based on the shape of the sealing ring. While electric cylinders are commonly used, their structure is simple but costly. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a sealing ring oiling mechanism and a sensor cover assembly device, which can apply oil to non-circular sealing rings and realize sealing ring oiling and sealing plug pressing in one station.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a sealing ring oiling mechanism for applying oil to a sealing ring fitted on a workpiece, comprising: A contouring rotating wheel is provided with a fixed seat on which the workpiece is fixed. The contouring rotating wheel and the sealing ring have the same shape, and the projection of the contouring rotating wheel on the sealing ring can cover the sealing ring. The contouring rotating wheel and the sealing ring rotate coaxially and in the same phase. An oiling assembly includes a slide plate located on one side of the contouring rotating wheel. The slide plate abuts against the contouring rotating wheel and can move along a first direction on the horizontal plane under the push of the contouring rotating wheel. An oiling head is provided on the slide plate. An elastic pusher member is provided, which continuously pushes the slide plate toward the contouring rotating wheel so that the slide plate abuts against the contouring rotating wheel. The beneficial effects of this invention are as follows: A contour-following rotating wheel, similar in shape to the sealing ring, is used in conjunction with an elastic pusher to ensure that the sliding plate always abuts against the side wall of the contour-following rotating wheel. This maintains a constant distance between the oiling head and the sealing ring, meaning the oiling head is always in the oiling position for applying oil to the sealing ring. There is no need to calculate the trajectory of the sealing ring; oiling is performed using a mechanical structure. A single elastic pusher keeps the oiling head in the oiling position, simplifying the structure and saving costs.

[0005] Furthermore, the skateboard includes a skateboard body, on which rollers are rotatably connected, and the rollers and the sidewalls of the contouring rotating wheel make rolling contact. The rollers reduce friction between the skateboard and the contouring rotating wheel, and the rolling contact reduces wear on the contouring rotating wheel. Furthermore, the sealing ring oiling mechanism also includes a worktable, on which a rotary drive component is fixed to drive the contouring rotating wheel to rotate, and the elastic push component is fixed to the worktable.

[0006] Furthermore, an adjusting cylinder is fixed on the slide plate, and the oiling head is fixedly connected to the piston rod of the adjusting cylinder. The adjusting cylinder can adjust the position of the oiling head relative to the slide plate in a first direction. The adjusting cylinder adjusts the position of the oiling head according to usage requirements. Furthermore, the elastic pusher is a cylinder, the piston of the cylinder is fixedly connected to the slide plate, and the cylinder always applies a thrust to the slide plate in the first direction to move towards the contouring rotating wheel.

[0007] Furthermore, a guide rail extending along a first direction is fixed on the worktable, and the slide slides along the guide rail, which guides the movement of the slide.

[0008] Furthermore, the worktable is also equipped with a sensor, and the contouring rotating wheel is equipped with a sensing block that corresponds to and can be detected by the sensor. The sensor detects the rotation angle of the contouring rotating wheel to ensure that the contouring rotating wheel rotates one revolution.

[0009] Furthermore, a vision inspection component is also fixed on the skateboard, which takes a picture of the sealing ring.

[0010] This utility model also discloses a sensor cover assembly device, including the aforementioned sealing ring oiling mechanism. The sensor cover assembly device further includes a pressing mechanism, which includes a pressing head positioned above the workpiece and holding a sealing plug. The pressing head moves up and down under the drive of a servo press to insert the sealing plug into the mounting hole of the workpiece. The sensor cover assembly device can simultaneously oil the sealing ring and insert the sealing plug into the mounting hole, thus completing two processing steps for the steering gear.

[0011] Furthermore, the pressing mechanism also includes a clamping assembly, which includes a mounting plate fixedly connected to the pressing head. A pressure rod that can move up and down is slidably connected to the mounting plate. A spring is sleeved on the pressure rod located below the mounting plate. When the pressure rod is not against the workpiece, the lower end face of the pressure rod is lower than the lower end face of the pressing head. When the pressing head moves down, the clamping assembly first presses the workpiece onto the mounting base to position the workpiece. When the pressing head moves up, it presses down on the workpiece to prevent the workpiece and the pressing head from moving up synchronously, thus achieving separation of the workpiece and the pressing head.

Detailed Implementation The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0013] This utility model discloses an oiling mechanism for a sealing ring 72, used for oiling the sealing ring 72 fitted onto the workpiece 71. See attached document. Figure 1 As shown, the sealing ring 72 on the workpiece 71 is a non-circular sealing ring 72.

[0014] See appendix Figure 2 As shown, the sealing ring 72 oiling mechanism includes a contoured rotating wheel 1, an oiling assembly 2, and an elastic pusher 3.

[0015] See appendix Figure 3 As shown, the contouring rotating wheel 1 is equipped with a fixed seat 11 on which the workpiece 71 is fixed. The contouring rotating wheel 1 and the sealing ring 72 have the same shape, and the projection of the contouring rotating wheel 1 onto the sealing ring 72 can cover the sealing ring 72. That is, the side wall of the contouring rotating wheel 1 is located outside the sealing ring 72 in the horizontal direction, and the contouring rotating wheel 1 is larger than the sealing ring 72. The contouring rotating wheel 1 and the sealing ring 72 rotate coaxially and in the same phase. The contouring rotating wheel 1 and the sealing ring 72 are placed in the same direction, so the rotation trajectory of the sealing ring 72 is the same as and parallel to the rotation trajectory of the outer wall of the contouring rotating wheel 1.

[0016] The oiling assembly 2 includes a slide plate 21 located on one side of the contouring rotating wheel 1. The slide plate 21 abuts against the contouring rotating wheel 1 and can move along a first direction on the horizontal plane under the push of the contouring rotating wheel 1. An oiling head 22 is provided on the slide plate 21. The elastic pusher 3 always pushes the slide plate 21 toward the contouring rotating wheel 1 so that the slide plate 21 abuts against the contouring rotating wheel 1.

[0017] In this embodiment, there is no need to calculate the trajectory of the sealing ring 72. Instead, a contour-following rotating wheel 1 with a shape similar to that of the sealing ring 72 is set up. With the help of the elastic pusher 3, the sliding plate 21 is always in contact with the side wall of the contour-following rotating wheel 1. In other words, the distance between the oiling head 22 and the sealing ring 72 remains constant, meaning that the oiling head 22 is always in the oiling position to apply oil to the sealing ring 72. Using a purely mechanical structure for oiling, a single elastic pusher 3 can keep the oiling head 22 always in the oiling position, simplifying the structure and saving costs.

[0018] For example, in this embodiment, the sealing ring 72 is elliptical, and the contouring rotating wheel 1 is also elliptical or a similarly structured cam. When the workpiece 71 is fixed on the fixed seat 11, the length direction of the sealing ring 72 is also the length direction of the contouring rotating wheel 1. Initially, the elastic pusher 3 pushes the slide plate 21 and the contouring rotating wheel 1 to abut against each other, and when the contouring rotating wheel 1 rotates, it can push the slide plate 21 to move along the first direction. However, during this process, the elastic pusher 3 always applies a force on the slide plate 21 that moves towards the contouring rotating wheel 1, so that the slide plate 21 always abuts against the contouring rotating wheel 1. At this time, the distance from the oiling head 22 to the sealing ring 72 remains unchanged, and oil can always be applied to the sealing ring 72.

[0019] See appendix Figure 4 and attached Figure 5 As shown, the skateboard 21 includes a skateboard body 211, on which a roller 212 is rotatably connected. The roller 212 and the side wall of the contouring rotating wheel 1 make rolling contact. The roller 212 is provided to reduce friction between the skateboard 21 and the contouring rotating wheel 1, and the rolling contact reduces wear on the contouring rotating wheel 1.

[0020] In one embodiment, an adjusting cylinder 23 is fixed on the slide plate 21, and the oiling head 22 is fixedly connected to the output end of the adjusting cylinder 23. The adjusting cylinder 23 can adjust the position of the oiling head 22 relative to the slide plate 21 in a first direction. By setting the adjusting cylinder 23, the position of the oiling head 22 relative to the slide plate 21 can be quickly adjusted. Before oiling, the position of the oiling head 22 can be quickly adjusted to ensure that the oiling head 22 can apply oil to the sealing ring 72. See appendix Figure 6 As shown, the sealing ring 72 oiling mechanism also includes a worktable 4. A rotary drive component 42, which drives the contouring rotating wheel 1 to rotate, is fixed on the worktable 4. The rotary drive component 42 is a rotary motor, which is fixed below the worktable 4. When the motor shaft of the rotary motor rotates, it can drive the contouring rotating wheel 1 and the workpiece 71 on it to rotate synchronously.

[0021] The elastic pusher 3 is fixed on the worktable 4. In one embodiment, the elastic pusher 3 is a cylinder, and the piston of the cylinder is fixedly connected to the slide plate 21. The cylinder always applies a thrust to the slide plate 21 in the first direction, moving it toward the contouring rotating wheel 1. The cylinder is a mini cylinder, meaning that the force applied by the cylinder to the slide plate 21 is small. The force applied by the cylinder to the slide plate 21 is opposite in direction to the force applied by the contouring rotating wheel 1 to the slide plate 21, and is smaller than the force applied by the contouring rotating wheel 1 to the slide plate 21. In this way, the thrust applied by the contouring rotating wheel 1 to the slide plate 21 can overcome the force applied by the elastic pusher 3 to the slide plate 21, causing the slide plate 21 to slide.

[0022] In one embodiment, the elastic pusher is a columnar spring 643, which extends along a first direction. One end of the columnar spring 643 is fixed to the worktable 4, and the other end is fixed to the slide plate 21. The columnar spring 643 is always in a compressed state.

[0023] To guide the sliding of skateboard 21 and ensure that skateboard 21 can only move in the first direction, see Appendix. Figure 5 As shown, a guide rail 41 extending in the first direction is fixed on the worktable 4, and the slide plate 21 slides along the guide rail 41.

[0024] See appendix Figure 6 As shown, a sensor 5 is also provided on the worktable 4, and a sensing block corresponding to and detectable by the sensor 5 is provided on the contouring rotating wheel 1. Initially, the sensing block and the sensor 5 rotate in opposite directions. When the contouring rotating wheel 1 rotates and the sensing block is detected by the sensor 5 again, it indicates that the contouring rotating wheel 1 has rotated one revolution, and the sealing ring 72 has completed the oiling. For example, the sensor 5 is a proximity sensor, which can detect the sensing block.

[0025] To inspect the sealing ring 72, a vision inspection component 24 is fixed on the slide plate 21. The vision inspection component 24 includes a camera and an aperture. The aperture is used to illuminate the sealing ring 72, and the camera takes a picture of the sealing ring 72. The vision inspection component 24 and the slide plate 21 move synchronously, meaning that the distance between the camera and the sealing ring 72 remains constant. This ensures that the vision inspection component 24 is always in focus when photographing the sealing ring 72, enabling the inspection of the sealing ring 72.

[0026] In one embodiment, a sensor cover assembly apparatus is also disclosed, including the aforementioned sealing ring oiling mechanism and pressing mechanism. The pressing mechanism is used to press the sealing plug 73 into the mounting hole of the workpiece 71. The sensor cover assembly apparatus can perform both oiling of the sealing ring 72 and pressing of the sealing plug 73 at one station.

[0027] See appendix Figure 7 As shown, the pressing mechanism includes a fixed frame 63 fixed on the worktable 4, a servo press 62 fixed on the fixed frame 63, and a pressing head 61 located directly above the mounting hole of the workpiece 71 connected to the output end of the servo press 62. The pressing head 61 can adsorb the sealing plug 73. The pressing head 61 moves up and down under the drive of the servo press 62 to insert the sealing plug 73 into the mounting hole of the workpiece 71.

[0028] The mounting hole is coaxial with the shaft of the contouring rotating wheel 1. At this time, the position of the mounting hole will not change during the rotation of the workpiece 71, ensuring that the mounting hole of the workpiece 71 is always aligned with the pressure head 61 in the vertical direction.

[0029] In one embodiment, the press-fitting mechanism further includes a clamping assembly 64 before the sealing plug 73 is inserted into the mounting hole, see Appendix Figure 8 As shown, the clamping assembly 64 includes a mounting plate 641 fixedly connected to the pressure head 61. A pressure rod 642 that can move up and down along the mounting plate 641 is slidably connected to the mounting plate 641. A spring 643 is sleeved on the pressure rod 642 located below the mounting plate 641. When the pressure rod 642 is not in contact with the workpiece 71, the lower end face of the pressure rod 642 is lower than the lower end face of the pressure head 61.

[0030] As the pressure head 61 moves downward under the drive of the servo press 62, the pressure rod 642 first abuts against the workpiece 71, pressing the workpiece 71 firmly onto the mounting base. At this point, the pressure head 61 continues to move downward, and the pressure rod 642 moves upward relative to the mounting plate 641, compressing the spring 643 until the pressure head 61 is pressed into the mounting hole. The servo press 62 then drives the pressure head 61 upward, separating it from the workpiece 71 initially, but the pressure rod 642 remains pressed against the workpiece 71 to prevent the workpiece 71 and the pressure head 61 from moving upward synchronously, thus achieving separation between the workpiece 71 and the pressure head 61. The servo press 62 continues to drive the pressure head 61 upward until it reaches the initial position where the pressure rod 642 and the workpiece 71 are separated.

[0031] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
