[0002] As a core component of the automobile steering structure, the performance of the steering rod is directly related to the stability of the tires, driving stability and the service life of the vehicle. Especially in complex road conditions and changing driving environments, the role of the steering rod is particularly critical. As an important component connecting the steering shaft and the steering rod, the operating state of the automobile ball head has a direct impact on the vehicle's handling performance. Once the ball head is damaged, problems such as abnormal chassis noise, unstable driving, and brake deviation will follow, seriously affecting driving safety. Especially when driving at high speeds or emergency braking, these problems may lead to serious consequences.

[0003] In order to deal with the problems caused by ball head damage, the design of the dust cover is particularly important. The main function of the dust cover is to prevent dust and other impurities from entering the ball head pin from the mating surface, reduce the wear of the ball head pin, and thus extend its service life. In order to achieve effective fastening of the dust cover, the prior art generally adopts a structure in which the bottom protrusion of the dust cover matches the groove of the ball head seat.

[0004] However, if the attached Figure 1 As shown in the figure, the design that the outer diameter of the bottom protrusion of the dust cover is smaller than the edge diameter of the groove of the ball seat, although it enhances the sealing and assembly tightness to a certain extent, it also brings the problem of assembly difficulty. This design makes it difficult for the dust cover to be accurately embedded in the groove during the assembly process, which not only affects the assembly efficiency, but also may cause poor sealing due to improper assembly, thereby affecting the use effect of the dust cover.

DETAILED DESCRIPTION

[0026] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0027] like Figures 2 to 5 As shown, this specific embodiment provides an automobile tie rod joint assembly device, including a base 3, an assembly seat, an assembly drive assembly, an inner support plate 12, and a spreading drive assembly. The base 3 is provided with an assembly seat movably arranged up and down. In the specific embodiment, the support seat is a C-shaped structure, including an upper support plate 9, a vertical plate 10 and a lower support plate 8. The assembly seat is connected with an assembly drive assembly. An assembly hole is provided on the lower support plate 8 of the assembly seat. At least three inner support plates 12 are radially arranged around the assembly hole. In the specific embodiment, six inner support plates 12 are provided, and the angle between adjacent inner support plates 12 is 60°. The inner support plate 12 is horizontally movably arranged on the lower support plate 8. A support hook is provided at the spreading end of the inner support plate 12 and can be extended into the assembly hole. The driving end of the inner support plate 12 is connected with the spreading drive assembly, and the spreading drive assembly can drive the inner support plate 12 to move radially along the assembly hole.

[0028] In this specific embodiment, the multiple radially moving inner support plates 12 can cause the outer circle of the bottom protrusion of the dust cover to be assembled to undergo elastic deformation so that the diameter is increased, and the ball head is inserted into it under the drive of the assembly seat, which facilitates assembly and greatly improves assembly efficiency.

[0029] like Figures 2 to 5As shown, the expansion drive assembly can use a cylinder or an electric cylinder, and each inner support plate 12 is provided with a corresponding cylinder or electric cylinder for driving. However, due to the large number of inner support plates 12 in this specific embodiment, it is necessary to ensure that each inner support plate 12 moves simultaneously and has the same radial displacement in order to ensure that the elastic deformation of the dust cover to be assembled is uniform, and the diameter expansion in all directions is the same, so that it can be assembled without interfering with the ball head. For this reason, in this specific embodiment, the expansion drive assembly includes a vertically arranged first expansion cylinder 5, and the first expansion cylinder 5 is arranged downward on the assembly seat. The first expansion cylinder 5 drives a second connecting plate 16, and a driving rod 7 is vertically arranged on the second connecting plate 16. The driving rod 7 is arranged one by one with the inner support plate 12, and a driving inclined surface is arranged on the outer side of the lower end of the driving rod 7, and the driving inclined surface can abut against the vertically arranged driving arm at the driving end of the inner support plate 12. Then, the lower end of the driving rod 7 is also provided with an avoidance groove, and the inner support plate 12 can move in the avoidance groove, and the driving end of the inner support plate 12 is horizontally provided with a return spring 11; through the action of the first support cylinder 5 and the driving rod 7, the vertical drive is converted into a horizontal drive to drive the corresponding inner support rod to move radially, the structure is simple, and at the same time, it is ensured that each inner support plate 12 can synchronize the inner support of the dust cover, and ensure that the elastic deformation of the dust cover is uniform, thereby improving the assembly quality; further, an L-shaped connecting arm is provided on the second connecting plate 16, and the connecting arm can be slidably connected to the vertical plate 10 of the assembly seat through a slide rail, and the slide rail can ensure that the second connecting plate 16 moves downward smoothly without jamming, and the second connecting plate 16 will not deflect, thereby ensuring that the downward movement distance of each driving rod 7 is the same, thereby ensuring that the radial movement distance of each inner support plate 12 is the same, further improving the assembly quality.

[0030] like Figure 3 and Figure 5 As shown, further, in the present specific embodiment, in order to ensure that the inner support plate 12 moves stably and does not separate from the lower support plate 8, in the present specific embodiment, a guide groove is provided on the lower support plate 8 around the assembly hole, and the guide groove is arranged one-to-one with the inner support plate 12. The inner support plate 12 is movably arranged in the guide groove, and a cover plate 13 is arranged on the upper part of the guide groove. The return spring 11 is horizontally arranged at one end of the guide groove away from the assembly hole; at the same time, a roller 14 is arranged on the driving arm, and the guide groove includes a widened portion, and the driving arm can move horizontally in the widened portion. By arranging the roller 14, the friction between the driving rod 7 and the driving arm is reduced to ensure the smooth operation of the device.

[0031] like Figure 2 and Figure 4As shown, when the inner support plate 12 opens the dust cover to be assembled and completes the assembly with the ball head under the drive of the assembly seat, a boss is arranged on the upper part of the joint to limit the dust cover. At this time, the assembly seat continues to move downward, and the support hook of the inner support rod can be separated from the dust cover. In order to prevent the support hook from scratching the outer surface of the dust cover during the resetting process of the assembly seat, in the present specific embodiment, the piston rod of the first support cylinder 5 is connected to the second support cylinder 6, and the second support cylinder 6 is vertically arranged on the second connecting plate 16. When the support hook is disengaged from the dust cover, the second support cylinder 6 extends out to drive the driving rod 7 to continue to move downward. At this time, the diameter of the circle surrounded by the ends of the multiple support hooks is partially enlarged and larger than the dust cover. When the assembly seat moves upward to reset, the support hook will not contact the dust cover and will not cause scratches.

[0032] like Figure 2 and Figure 3 As shown, in order to be able to position the dust cover to be assembled and avoid flanging during the diameter expansion process, the specific embodiment also includes a clamping tool, which includes a clamping cylinder 4, which is vertically arranged downward on the upper support plate 9, and the piston rod of the clamping cylinder 4 is connected to the first connecting plate 20. A connecting rod is arranged at the lower part of the first connecting plate 20. The connecting rod passes through the second connecting plate 16 and is successively connected to a pressure plate 15 and a positioning cover 17. The positioning cover 17 can wrap the dust cover to be assembled inside it, and the positioning cover 17 can move up and down driven by the clamping cylinder 4 through the connecting rod; in the specific embodiment, two connecting rods are relatively arranged, and the two ends of the positioning cover 17 are connected to the corresponding lower end of the connecting rod by a buffer spring 18. The cylinder body of the first expansion cylinder 5 is arranged on the first connecting plate 20, and the buffer spring 18 is used to avoid hard contact between the positioning cover 17 and the dust cover to be assembled, thereby reducing the force on the dust cover to be assembled.

[0033] like Figure 2 As shown, in this specific embodiment, the cylinder body of the first spreading cylinder 5 is arranged on the first connecting plate 20. By arranging the first spreading cylinder 5 on the first connecting plate 20, the clamping cylinder 4, the first spreading cylinder 5 and the second spreading cylinder 6 can be arranged in a straight line, thereby ensuring the stability of the device; the assembly drive assembly includes an assembly cylinder 1, which is vertically arranged downward on a support column 2 on a base 3, and the piston rod of the assembly cylinder 1 is connected to the upper support plate 9 of the assembly seat, and the assembly seat is slidably arranged on the support column 2.

[0034] The working process of the automobile tie rod joint assembly device is as follows:

[0035] The dust cover to be assembled is placed on the plane composed of multiple inner support plates 12 in the assembly hole, and then the clamping cylinder 4 is extended to drive the positioning cover 17 to move down to position the dust cover to be assembled; the first opening cylinder 5 is extended, and the driving rod 7 is moved down to drive the inner support rod to move in the direction away from the assembly hole. After the first opening cylinder 5 moves into place, the diameter of the dust cover to be assembled is expanded to be in place; the assembly cylinder 1 is extended to drive the assembly seat to move down, and the dust cover to be assembled is put on the ball pin until the short side of the dust cover interferes with the upper edge of the ball pin of the joint. The assembly cylinder 1 continues to move for a distance, and under the action of the resistance of the ball pin, the inner support plate 12 is separated from the dust cover. At the same time, the second inner support cylinder is extended, and the inner support plate 12 is further moved outward; after moving outward into place, the assembly cylinder 1 retracts, and the assembly seat moves up. At the same time, the clamping cylinder 4 retracts, and the positioning cover 17 moves up. Finally, the second inner support cylinder and the first inner support cylinder retract in turn, and the inner support plate 12 is reset to wait for the next installation.

[0036] From the above specific implementations, it can be seen that the utility model has the following beneficial effects:

[0037] 1. The radially arranged multiple inner support plates 12 can cause the outer circle of the bottom protrusion of the dust cover to be assembled to undergo elastic deformation so that the diameter is increased, which is convenient for assembly with the ball head;

[0038] 2. Through the action of the first opening cylinder 5 and the driving rod 7, the vertical drive is converted into the horizontal drive to drive the corresponding inner support rod to move radially. The structure is simple, and at the same time, each inner support plate 12 can achieve synchronization with the inner support of the dust cover, ensuring uniform elastic deformation of the dust cover, thereby improving the assembly quality;

[0039] 3. The friction between the driving rod 7 and the driving arm is reduced by setting the roller 14 to ensure the smooth operation of the device;

[0040] 4. The second connecting plate 16 is slidably connected to the vertical plate 10 to ensure the smooth downward movement of the second connecting plate 16, ensure the downward movement distance of each driving rod 7 is the same, and further ensure the radial movement distance of each inner support plate 12 is the same;

[0041] 5. By providing the second opening cylinder 6, a secondary opening movement can be achieved after the inner support plate 12 is detached from the dust cover to be assembled, thereby preventing the inner support rod from scratching the dust cover;

[0042] 6. The dust cover can be positioned by setting a clamping tool. On the one hand, the dust cover to be assembled can be positioned, and on the other hand, the dust cover can be prevented from flanging due to its own elasticity during the expansion process;

[0043] 7. Use the buffer spring 18 to prevent the positioning cover 17 from hard contact with the dust cover to be assembled, thereby reducing the force acting on the dust cover to be assembled;

[0044] 8. By arranging the first expanding cylinder 5 on the first connecting plate 20, the clamping cylinder 4, the first expanding cylinder 5 and the second expanding cylinder 6 can be arranged in a straight line, thereby ensuring the stability of the device.
