DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0028] Example

[0029] like Figure 3As shown, in this embodiment, a new type of connecting rod ball pin dust cover 4 assembly mechanism is mainly disclosed, which is mainly used for the installation of dust covers 4 with a small thickness and width ratio. It should be emphasized that other matching devices can be set before and after this device. For example, after the dust cover 4 is installed, a metal coil 3 is also provided to fix the two ends of the dust cover 4, such as Figure 1 , 2, the connecting rod ball pin includes a ball pin seat 2 and a ball pin rod 1, the small end 41 of the dust cover 4 is fixed on the ball pin rod 1, and the large end 42 of the dust cover 4 is fixed on the ball pin seat 2.

[0030] Specifically, the new connecting rod ball pin dust cover assembly mechanism includes: a blow pipe 10, a pushing component 20 and a cone sleeve 30; wherein the air inlet end of the blow pipe 10 is connected to the air supply device 28, and the air outlet end is provided with a tapered hole 122, wherein the diameter of the tapered hole 122 becomes larger and larger outward to abut against the top of the cone sleeve 30 to ensure the connection strength and sealing; In addition, the pushing component 20 is sleeved on the outside of the blow pipe 10 and the two are slidably arranged, and a compression spring 11 is provided between the pushing component 20 and the blow pipe 10 along the axial direction of the blow pipe 10. It should be emphasized here that the compression spring 11 is provided between the pushing component 20 and the blow pipe 10. The main execution action of the spring 11 is compression. At the same time, the compression spring 11 is arranged between the pushing component 20 and the blow pipe 10. When the pushing component 20 moves, the blow pipe 10 does not move. At this time, the compression spring 11 will be squeezed. Under the action of the compression spring 11, the blow pipe 10 begins to move with the pushing component 20; in addition, one end of the pushing component 20 is provided with a telescopic rod 211 that drives the pushing component 20 to move along its own axial direction. The telescopic rod 211 uses but is not limited to an electric telescopic rod 211, a pneumatic telescopic rod 211 or a hydraulic telescopic rod 211.

[0031] For the placement piece cone sleeve 30 of the dust cover 4, as shown in FIG. Figure 10 , as shown in 11, it is a frustum structure with a small upper part and a large lower part and is provided with a vent hole 31 and a mounting hole 32 inside. The mounting hole 32 is arranged in conjunction with the ball pin rod 1. Generally, the ball pin rod 1 is arranged vertically, and the cone sleeve 30 is placed on the ball pin rod 1 through the mounting hole 32; after the mounting hole 32 is fitted with the ball pin rod 1, the air inlet end of the air hole 31 is connected to the air outlet end of the blowpipe 10, and the air outlet end of the air hole 31 is located at the installation position of the dust cover 4 (large mouth end 42).

[0032] The whole working process is as follows: Figure 6-9As shown, first place the cone sleeve 30 on the vertically arranged ball pin rod 1, then place the dust cover 4 on the cone sleeve 30, drive the telescopic rod 211 to drive the push assembly downward, and under the action of the compression spring 11, the blow pipe 10 moves downward along with the push assembly 20, and the blow pipe 10 abuts the top of the cone sleeve 30 through the tapered hole 122, and then the push assembly 20 contacts the dust cover 4, continue to drive the telescopic rod 211, and the push assembly 20 drives the dust cover 4 to move downward together, and expands the diameter through the cone sleeve 30 until the dust cover 4 The large-mouthed end of the dust cover 4 is separated from the cone sleeve 30 and is located on the ball pin seat 2. At this time, air is supplied to the blowpipe 10 through the air supply device 28, and the large-mouthed end of the dust cover 4 is expanded by air pressure and is sleeved on the ball pin seat 2. Then the air is released, the equipment is restored, and the cone sleeve 30 is pulled out. It should be emphasized that a device can be provided later to ensure that the small-mouthed end 41 of the dust cover 4 is accurately positioned and the metal coil 3 is bundled. However, this does not affect the implementation of the present invention, so the subsequent device will not be described in detail here, and existing equipment or manual methods can be used.

[0033] It should also be noted that, in other embodiments, the pushing component 20 is the first contact member that contacts the dust cover 4, and its specific structure is not limited in this embodiment, as long as it meets the above-mentioned functional requirements, such as being set to a cylindrical shape; further, an elastic abutment can be provided on the cylindrical pushing component 20, and the elastic abutment is provided to abut the dust cover 4 along the movement direction of the pushing component 20; the elastic abutment can be made of rubber here.

[0034] like Figure 4-6 As shown, in this embodiment, as mentioned above, the dust cover 4 needs to be assisted by a tapered sleeve 30 with a variable diameter to ensure that the large-mouth end and the large-mouth end are expanded to complete the installation. In the process of the dust cover 4 changing its diameter, the size of the contact area between the pushing component 20 and the dust cover 4 directly ensures the reliability of the installation of the dust cover 4. Therefore, if a cylindrical pushing component 20 with a fixed diameter is used, there will be a large gap between it and the tapered sleeve 30, and there is a possibility that the dust cover 4 will be squeezed and deformed into the gap, resulting in installation failure.

[0035] Therefore, in this embodiment, the pushing components 20 are provided with a structure with a variable diameter, specifically, Figure 56, the elastic abutment includes a cylinder 25 and a push claw 24, and the pushing assembly 20 includes, from top to bottom,: a connecting cylinder 21, a connecting disk 22 and a conical seat 23; wherein, the top of the connecting cylinder 21 is connected to the movable end of the telescopic rod 211, and the fixed end of the telescopic rod 211 is fixedly set through the frame 40; the conical seat 23 is a frustum with a larger upper portion and a smaller lower portion, and the side surfaces of the conical seat 23 are evenly provided with slide rails 26, generally with 3, one end of the push claw 24 is slidably set on the slide rail 26, and the other end is abutted against the dust cover 4; one end of the cylinder 25 is connected to the connecting disk 22, and the other end is connected to the push claw 24; the telescopic rod 211 drives the pushing assembly 20 to move downward During the process, the push claw 24 contacts the dust cover 4. When the dust cover 4 changes diameter on the tapered sleeve 30, the resistance of the push claw 24 becomes larger, and the cylinder 25 is compressed to slide on the conical seat 23, thereby driving the push claw 24 to expand outward, realizing its function of following the diameter change of the dust cover 4. In addition, the cylinder 25 can also be controlled manually to achieve operational reliability; in addition, the bottom of each of the three push claws 24 is provided with an abutment block 27; the interior of the abutment block 27 is provided with a groove that fits the dust cover 4; through the groove and the elastic abutment provided with the diameter change, the contact area between the pushing component 20 and the dust cover 4 is always maintained, thereby improving the reliability of equipment installation.

[0036] In addition, in this embodiment, a bracket 50 is further provided, and the bracket 50 is connected to the fixed end of the telescopic rod 211, that is, the bracket 50 is fixedly connected to the frame 40 here; the bracket 50 is used to place the ball pin seat 2; a detection component 60 is provided on the bracket 50, and the detection component 60 is used to detect the position of the ball pin seat 2, so as to accurately locate it during the automated installation process. The detection component 60 can use the existing WRX-40N laser sensor; it should also be emphasized that, if Figure 3 As shown, a relief opening 15 is provided on the connecting tube 21 , and the air supply device 28 passes through the relief opening 15 to connect to the blowpipe 10 .

[0037] This embodiment also discloses a novel method for assembling a connecting rod ball pin dust cover, comprising the following steps:

[0038] S1: Place the dust cover 4 on the small end of the cone sleeve 30, and place the cone sleeve 30 on the ball pin rod 1;

[0039] S2: driving the pushing assembly 20 to push the dust cover 1 to the large end of the cone sleeve 30;

[0040] S3: Blow air into the dust cover 4 through the cone sleeve 30 so that the large end of the dust cover 4 is sleeved on the ball pin seat 2;

[0041] S4: Take out the cone sleeve 30 and put the small end of the dust cover 4 on the ball pin rod 1.

[0042] Finally, it should be emphasized that in this embodiment, only the main invention points are described in detail, and non-essential invention points can adopt existing technical solutions, such as: air supply device 28, etc.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
