Description

Technical Field

[0001] This utility model relates to a lower clamping ring assembly device for a steering and suspension ball joint dust cover, belonging to the technical field of steering and suspension ball joint dust cover assembly. Background Technology

[0002] In the field of steering and suspension ball joint assembly technology, after the dust cover is installed, a lower clamping ring needs to be installed at its lower annular groove position to clamp and fix the lower end of the dust cover. The traditional method of installing the lower clamping ring is done by hand using a hook, which currently presents the following problems in the production process: 1. Manual operation is inefficient and labor-intensive, directly affecting production efficiency; 2. The process requires highly skilled operators, and improper operation can easily damage the dust cover, leading to poor product sealing; 3. There are potential product quality risks, which may cause premature failure of the final product; 4. There are safety hazards during the operation, which may lead to personnel injury in severe cases. With technological advancements, the installation of the lower clamping ring can now be automated through mechanization, effectively solving the above problems. Existing lower collar installation equipment, such as the automatic assembly machine for tie rod dust cover retaining rings disclosed in utility model patent CN213916971U, while meeting production requirements to a certain extent, requires multiple sets of cylinders to cooperate to complete the installation. This multi-cylinder coordination is prone to errors, leading to low installation efficiency. Furthermore, in existing assembly machines, the umbrella cover is not properly positioned after being placed on the workpiece dust cover. When the chuck pushes the retaining ring along the umbrella cover, the umbrella cover is easily dislodged from the installation position, resulting in a high assembly error rate. Therefore, it is necessary to develop a new assembly method to solve the above-mentioned problems existing in the current assembly methods for lower collars of steering and suspension ball joint dust covers. Summary of the Invention

[0003] The purpose of this utility model is to provide an assembly device for the lower clamp ring of the steering and suspension ball joint dust cover with an ingenious structural design and a reasonable and compact layout, so as to solve the problems of low installation efficiency and high assembly error rate of the existing assembly method of the lower clamp ring of the steering and suspension ball joint dust cover.

[0004] The technical solution of this utility model is:

[0005] A device for assembling the lower retaining ring of a steering and suspension ball joint dust cover includes a mounting base, an umbrella cover, a compression claw, a lifting slide, a clamping mechanism, a control plate, a limiting rod, and a sliding plate. The device is characterized in that: a positioning block is mounted on the mounting base; a lifting slide is mounted on the mounting base above the positioning block via a slide rail; a lifting cylinder is mounted on the mounting base above the lifting slide; a sliding plate is slidably mounted on the lifting slide via symmetrically arranged sliding rods; the lifting cylinder is connected to the sliding plate; a return spring is fitted onto the sliding rod below the sliding plate; a compression claw and a control plate are mounted at the bottom end of the sliding plate; a limiting rod is slidably mounted on the sliding plate inside the compression claw via a guide hole; a compression spring is mounted on the limiting rod; an umbrella cover is mounted on the lifting slide below the compression claw via a clamping mechanism; and the sliding plate is connected to the clamping mechanism.

[0006] The upper and lower ends of the limiting slide rod are provided with limiting ends; the upper end of the limiting slide rod extends above the sliding plate and is fitted with a limiting end; a compression spring is fitted on the limiting slide rod below the sliding plate.

[0007] The compression claw includes multiple sets of claw segments, a circular spring, and a support lug; the multiple sets of claw segments are connected to each other to form a cylindrical structure; a circular spring is fitted on the outer side of the multiple sets of claw segments; a support lug is provided at the upper end of the claw segment; the support lug is hinged to the sliding plate by a pin.

[0008] The control plate is wider at the top and narrower at the bottom; vertical control sliding surfaces are symmetrically arranged at the lower end of the control plate; an inclined control sliding surface is connected to the upper end of the vertical control sliding surface; the control plate is slidably connected to the clamping mechanism through the vertical control sliding surface and the inclined control sliding surface.

[0026] The steering and suspension ball joint dust cover lower clamping ring assembly device includes a mounting base 1, an umbrella cover 13, a compression claw 8, a lifting slide 3, a clamping mechanism 12, a control plate 9, a limit slide bar 10, and a sliding plate 6.

[0027] Mounting base 1 is equipped with positioning block 2 (see instruction manual). Figure 1 and 2 The positioning block 2 is provided with a positioning countersunk hole 15 (see the instruction manual appendix). Figure 1 , 2 (and 4). The purpose of setting the positioning countersunk hole 15 is to ensure that the workpiece 32 can be placed on the positioning block 2 in a uniform posture through the positioning countersunk hole 15 during operation (see the instruction manual appendix). Figure 4 ).

[0028] The mounting base 1 above the positioning block 2 is equipped with a lifting slide 3 via a slide rail 34 (see instruction manual appendix). Figure 1 , 2 (and 3). The lower end of the slide rail 34 is equipped with a limit block 33 (see the instruction manual appendix). Figure 1 and 2 When the lifting carriage 3 moves to the bottom of the slide rail 34, the limiting block 33 can prevent it from moving further.

[0029] A lifting cylinder 4 is mounted on the mounting base 1 above the lifting slide 3; a sliding plate 6 is slidably mounted on the lifting slide 3 via symmetrically arranged sliding rods 5; the lifting cylinder 4 is connected to the sliding plate 6. When the lifting cylinder 4 is working, it can drive the lifting slide 3 to move together through the sliding plate 6.

[0030] A return spring 7 is fitted on the slide rod 5 below the sliding plate 6; during operation, the sliding plate 6 can overcome the elastic force of the return spring 7 and move downward relative to the lifting slide 3.

[0031] The bottom end of the sliding plate 6 is equipped with a pressing claw 8 and a control plate 9 (see the instruction manual). Figure 1 , 2 and 3).

[0032] The control plate 9 is wider at the top and narrower at the bottom; vertical control sliding surfaces 20 are symmetrically arranged at the lower end of the control plate 9; an inclined control sliding surface 21 is connected to the upper end of the vertical control sliding surface 20; the control plate 9 is slidably connected to the clamping mechanism 12 through the vertical control sliding surface 20 and the inclined control sliding surface 21 (see the appendix of the instruction manual). Figure 9 ).

[0033] The compression jaw 8 includes multiple sets of jaw flaps 16, circular springs 17, and lugs 18; the multiple sets of jaw flaps 16 are interconnected to form a cylindrical structure; circular springs 17 are fitted on the outer sides of the multiple sets of jaw flaps 16; lugs 18 are provided at the upper ends of the jaw flaps 16; lugs 18 are hinged to the sliding plate 6 via pins 19 (see the attached instruction manual). Figure 3 and 11 When the claw flap 16 is subjected to internal force, it can overcome the elastic force of the circular spring 17 and open outward; when the claw flap 16 loses its internal support, it can quickly return to its original position under the action of the elastic force of the circular spring 17. The lower end of the claw flap 16 has an inwardly bent structure (see the instruction manual appendix). Figure 11 This ensures that the lower end of the claw flap 16 remains in contact with the surface of the umbrella cover 13 during operation.

[0034] A limiting slide rod 10 is slidably mounted on the sliding plate 6 inside the compression claw 8 through a guide hole. Both the upper and lower ends of the limiting slide rod 10 are provided with limiting ends 14; the upper end of the limiting slide rod 10 extends above the sliding plate 6 and is fitted with the limiting end 14; a compression spring 11 is fitted onto the limiting slide rod 10 below the sliding plate 6 (see the attached instruction manual). Figure 7 and 8 The purpose of setting the limiting slide bar 10 in this way is that when the lower end of the limiting slide bar 10 abuts against the umbrella cover 13 during operation, the limiting slide bar 10 can maintain a fixed relative position with the umbrella cover 13. Then, the sliding plate 6 continues to move downward, and during its downward movement, it can compress the compression spring 11, so that the limiting slide bar 10 presses the umbrella cover 13 tightly under the action of the elastic force. In this way, the problem of high assembly error rate caused by the lack of limiting and pressing of the umbrella cover 13 can be avoided.

[0035] An umbrella cover 13 is mounted on the lifting slide 3 below the squeezing claw 8 via a clamping mechanism 12.

[0036] The clamping mechanism 12 includes a transverse slide 22, a clamping arc plate 23, a spreading spring 27, a guide plate 25, and a guide rod 26 (see the attached instruction manual). Figure 5 and 6 ).

[0037] The bottom end of the lifting slide 3 is symmetrically mounted with a transverse slide 22 via a guide rail; the inner side of the transverse slide 22 is equipped with a clamping arc plate 23 and a guide roller 24; the guide roller 24 is rotatably connected to the control plate 9.

[0038] A guide rod 26 is movably mounted on the lifting slide 3 outside the transverse slide 22 via a guide plate 25; the guide rod 26 is fixedly connected to the transverse slide 22; a spreading spring 27 is fitted on the guide rod 26. Under the action of the spreading spring 27, the transverse slides 22 always tend to move closer together. This serves two purposes: first, when the umbrella cover 13 is located between the clamping arc plates 23, the clamping arc plates 23 can clamp and fix the umbrella cover 13 under the action of the spreading spring 27; second, it ensures that the guide roller 24 always maintains contact with the control plate 9. When the control plate 9 moves downward relative to the lifting slide 3, the inclined control surface 21 can squeeze the guide roller 24, causing it to drive the transverse slides 22 to separate, thus achieving the purpose of releasing the umbrella cover 13 by the clamping arc plates 23.

[0039] The umbrella cover 13 has an integrated rotating structure, including an ellipsoid 28 and a guide cone 29; the guide cone 29 is provided at the lower end of the ellipsoid 28; multiple expansion joints 30 are provided on the guide cone 29; a positioning bending body 31 is provided inward at the lower end of the guide cone (see the appendix of the instruction manual). Figure 11 The purpose of setting the umbrella cover 13 in this way is that, during the downward movement of the umbrella cover 13, the dust cover of the workpiece 32 can open the guide cone 29 through the expansion joint 30. When the positioning bending body 31 moves to the assembly ring groove of the lower binding ring of the dust cover, it can be inserted into the inside of the assembly ring groove under its own elastic force. In this way, the lower binding ring can move along the outer surface of the umbrella cover 13 to the inside of the assembly ring groove of the dust cover during operation, thus completing the assembly work.

[0040] When the steering and suspension ball joint dust cover lower clamping ring assembly device is in operation, the steering and suspension ball joint (workpiece 32) to be assembled is first placed on the positioning block 2 through the positioning countersunk hole 15 (see the instruction manual appendix). Figure 3 and 4 Then, the lower band ring to be assembled is placed on the outer surface of the umbrella cover 13 and then placed on the outer surface of the clamping arc plate 23.

[0041] After the above work is completed, the lifting cylinder 4 drives the sliding plate 6 to move downwards; during the downward movement of the sliding plate 6, the compression spring 11 drives the lifting slide 3 to move downwards together. During the downward movement of the lifting slide 3, it can drive the umbrella cover 13 to move downwards together; during the downward movement of the umbrella cover 13, the dust cover of the workpiece 32 can be inserted into the interior of the umbrella cover 13. During this process, the dust cover can open the guide cone 29 through the expansion joint 30. When the positioning bending body 31 moves to the assembly ring groove of the lower binding ring of the dust cover, it can be locked into the interior of the assembly ring groove under its own elastic force. At this time, the lifting slide 3 moves to the bottom end of the slide rail 34 and abuts against the limit block 33.

[0042] When the positioning bending body 31 of the umbrella cover 13 is engaged into the assembly ring groove of the lower binding ring of the dust cover, and the lifting slide 3 abuts against the limiting block 33, the lifting cylinder 4 drives the sliding plate 6 to continue to move downward. At this time, the sliding plate 6 will drive the pressing claw 8 and the control plate 9 to move downward relative to the clamping mechanism 12.

[0043] During the downward movement of the compression claw 8 and control plate 9, when the compression claw 8 contacts the umbrella cover 13, the umbrella cover 13 can open the claw flap 16 from the inside, allowing the lower end of the claw flap 16 to slide along its surface. Simultaneously, the control plate 9, through the inclined control slide surface 21, compresses the guide roller 24, causing it to drive the transverse slide block 22 to separate, thus releasing the umbrella cover 13 from the clamping arc plate 23. During this process, the lower end of the limiting slide rod 10 abuts against the top of the umbrella cover 13, maintaining a fixed relative position. Meanwhile, the sliding plate 6 continues to move downward, compressing the compression spring 11 during this movement, causing the limiting slide rod 10 to press the umbrella cover 13 under the action of the elastic force.

[0044] As the sliding plate 6 continues to move downward, the clamping arc plate 23 releases the umbrella cover 13, the limiting slide rod 10 presses and fixes the umbrella cover 13, and the squeezing claw 8 can push the lower tie ring downward along the surface of the umbrella cover 13 until it moves into the interior of the assembly ring groove of the dust cover, thus completing the assembly of the lower tie ring.

[0045] After the assembly device completes the assembly of the lower clamping ring, the lifting cylinder 4 drives the sliding plate 6 to move upward and reset. During the upward movement of the sliding plate 6, when the pressing claw 8 moves to the upper surface of the clamping arc plate 23, the clamping arc plate 23 tightens the umbrella cover 13 again. Then the pressing claw 8 and the limiting slide rod 10 disengage from the umbrella cover 13. After that, the lifting cylinder 4 drives the sliding plate 6 to continue moving upward until the lifting slide 3 is moved to the initial position. Then a new workpiece 32 is installed, and the lower clamping ring assembly device can enter the next working cycle.

[0046] The assembly device for the lower clamp ring of the steering and suspension ball joint dust cover is ingeniously designed and has a reasonable and compact layout. The assembly of the lower clamp ring can be completed by a single lifting cylinder 4. Due to its simple structure, the product changeover speed is significantly improved. During the operation, the limiting slide rod 10 can press the umbrella cover 13 tightly under the elastic force of the compression spring 11, thus avoiding the problem of high assembly error rate caused by the umbrella cover 13 slipping off. It is particularly suitable for the needs of assembling the lower clamp ring of the steering and suspension ball joint dust cover.
