[0002] The mechanism of the automobile stabilizer bar mainly consists of a bar body and a ball pin arranged at the end of the bar body, and the ball pin at the end of the bar body is movably connected with the bar body. Therefore, in order to improve the safety and stability of the automobile stabilizer bar during use, a dust cover needs to be installed on the ball pin to prevent dust or other impurities from entering the installation position of the ball pin seat and the ball pin.

[0003] The existing dust cover assembling is mostly assembled by manual operation. Generally, in order to facilitate sealing, the lower lip of the dust cover is provided with a closing opening at the clamping end of the ball pin. However, the setting of the closing opening requires the fingers of the operator to pull open the lower lip of the dust cover before assembling. However, due to the hard rubber of the dust cover and the circular outer surface of the dust cover, it is difficult to operate the pulling open action of the lower lip of the dust cover during manual installation, which easily leads to the problems of improper installation and low efficiency of manual installation.

[0004] In addition, due to the non-uniform force of manual installation, the manual installation easily leads to the situations of the lower lip of the dust cover sticking to the grease of the neck of the ball pin, the improper installation of the dust cover, and the turning up of the lower lip of the dust cover, which not only increases the labor intensity, but also cannot guarantee the installation quality of the dust cover.

[0074] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0075] The present embodiment relates to a dust cover assembly device for assembling a dust cover 9 on a ball pin seat, which comprises a base body 1, a fixing seat 2, a spreading mechanism 3 and a pressing assembly mechanism 4 arranged on the base body 1. The fixing seat 2 has a fixing part 201 for fixing the ball pin seat on which a ball pin is installed. The spreading mechanism 3 comprises a first driving part 301 for outputting transverse driving force, a second driving part 302 for outputting longitudinal driving force, and a spreading claw unit arranged on the power output end of the second driving part 302.

[0076] The spreading claw unit of the present embodiment is used to support the dust cover 9 pre-assembled on the ball pin, and the spreading claw unit comprises a plurality of spreading claws 303 arranged around the fixing part 201. The first driving part 301 is connected to the spreading claw unit through a transmission unit 304, and the first driving part 301 can drive the spreading claw unit to switch between a first state and a second state through the transmission unit 304. In the first state, the plurality of spreading claws 303 are folded together to be inserted into the dust cover 9, and in the second state, the plurality of spreading claws 303 are away from each other to spread the dust cover 9.

[0077] Furthermore, the pressing assembly mechanism 4 of the present embodiment comprises a third driving part 401 for outputting longitudinal driving force, and a pressing assembly part 402 arranged on the power output end of the third driving part 401, and the pressing assembly part 402 is arranged above the fixing seat 2. The third driving part 401 can drive the pressing assembly part 402 to descend, so that the pressing assembly part 402 presses the spread dust cover 9 on the ball pin seat.

[0078] The dust cover assembly device of the present embodiment fixes the ball pin seat on the fixing part 201, drives the spreading claw unit to move upward along the longitudinal direction through the second driving part 302, and drives the plurality of spreading claws 303 to fold together through the first driving part 301, so that the folded spreading claws 303 are arranged below the dust cover 9. Then, the first driving part 301 drives the plurality of spreading claws 303 to spread away from each other to spread the dust cover 9, and then drives the pressing assembly part 402 to continue to descend to assemble the spread dust cover 9 on the mounting position of the ball pin seat.

[0079] In this way, full-automatic assembly of the dust cover 9 is achieved, and the third driving part 401 is used to control the lowering distance of the dust cover 9, so that the installation position of the dust cover 9 is accurate, and the first driving part 301 is used to drive the support claw 303 to switch between the first state and the second state, so that the lower lip of the dust cover 9 is automatically opened, thereby avoiding installation defects of the dust cover 9, improving production efficiency, and meeting the production needs of enterprises.

[0080] Based on the above overall introduction, an exemplary structure of the dust cover assembly equipment of the embodiment is shown in Figures 1 to 4 The base body 1 of the embodiment is a seat body for arranging the fixing seat 2, the opening mechanism 3, and the pressing mechanism 4. The base body 1 of the embodiment includes a base 102, a guard plate 103 arranged on both sides of the base 102, and a back plate 104 arranged on the back of the base 102. In the embodiment, the side facing the operator is the front, and the side facing away is the back.

[0081] As shown in Figure 1 , Figure 2 , Figure 5 The fixing seat 2 is cylindrical and protrudes above the base 102. The middle of the fixing seat 2 is formed with a circular hole, and the circular hole has an opening penetrating in the height direction near the front side of the base 102. The circular hole is the fixing part 201 for fixing the ball pin seat.

[0082] As a preferred embodiment, the base body 1 of the embodiment is provided with a support seat 7 arranged apart from the fixing seat 2, and the support seat 7 is used to support the pull rod connected to the ball pin seat. As shown in Figure 1 and Figure 2 The support seat 7 is arranged on the front of the base 102, and the support seat 7 of the embodiment includes a mounting seat 701 and a support plate 702 arranged above the mounting seat 701.

[0083] In order to facilitate arrangement, a V-shaped through slot 202 is arranged above the support plate 702. Since the assembly of the dust cover 9 is arranged after the assembly process of the pull rod and the ball pin seat, the support seat 7 is arranged to support the pull rod to make the ball pin seat parallel to the base 102 and perpendicular to the upper pressing mechanism 4, so that the position between the dust cover 9 and the ball pin seat is accurate.

[0084] As shown in Figure 1 , Figure 2 and Figure 5As shown, the fixed seat 2 of the embodiment is fixedly connected with the upper surface of the base 102 by bolts. A through slot 202 is formed on the fixed seat 2 for each supporting claw 303 to pass through, and there are four through slots 202 along the radial direction of the fixed seat 2, and each through slot 202 penetrates along the thickness direction of the fixed seat 2. When the supporting claw unit switches between the first state and the second state, each supporting claw 303 slides in the through slot 202.

[0085] As shown, Figure 1 and Figure 2 As shown, the base 102 of the embodiment is formed with an inner cavity, and the transmission unit 304 is arranged in the inner cavity of the base 102. In addition, the third driving part 401 is fixedly connected to the top of the base body 1. As shown, Figures 1 to 4 As shown, the first driving part 301, the second driving part 302 and the third driving part 401 of the embodiment all adopt telescopic air cylinders. The first driving part 301 is arranged below the back of the base body 1 and corresponds to the position of the transmission unit 304.

[0086] As shown, Figures 1 to 4 As shown, the second driving part 302 of the embodiment is fixedly connected to the top of the base body 1, and the power output end of the second driving part 302 is connected with a lifting seat 305. The lifting seat 305 of the embodiment includes a vertical plate 3051 arranged along the height direction of the base body 1 and a horizontal plate 3052 horizontally arranged in the inner cavity of the base 102, and the transmission unit 304 is arranged on the horizontal plate 3052. When the second driving part 302 drives the lifting seat 305 to move up and down, the supporting claw unit, the transmission unit 304 and the second driving part 302 can all move up and down to realize the lifting or lowering of each supporting claw 303.

[0087] As a preferred embodiment, the transmission unit 304 of the embodiment includes a transmission disc 3041 rotatably arranged below the fixed seat 2 and a driving block 3042 arranged at the power output end of the first driving part 301. As shown, Figures 3 to 7 As shown, the transmission disc 3041 is formed in a disc structure, and the driving block 3042 is formed in a U-shaped block with an upward opening. When the first driving part 301 drives the driving block 3042 to slide along the front and back direction of the base 102, the driving block 3042 can drive the transmission disc 3041 to rotate.

[0088] Further, the transmission disc 3041 of the embodiment is constrained in the groove 30421 of the driving block 3042 by a transmission member arranged at the bottom of the transmission disc 3041. The transmission disc 3041 is provided with a limiting groove 30411 corresponding to each supporting claw 303, and each supporting claw 303 is slidably arranged in the corresponding limiting groove 30411. The first driving part 301 can drive the transmission disc 3041 to rotate and switch the supporting claw unit between the first state and the second state by driving the driving block 3042 to move.

[0089] AsFigure 7 , Figure 8 as well as Figure 9 As shown, the transmission disc 3041 is positioned below the horizontal plate 3052. (Combined with...) Figure 7 and Figure 11 As shown, the limiting groove 30411 on the transmission disk 3041 is an arc-shaped long groove. The transmission component is limited in the limiting groove 30411. When the transmission disk 3041 is driven to rotate, the transmission component slides radially along the transmission disk 3041 due to the action of the limiting groove 30411.

[0090] like Figures 11 to 13 As shown, in this embodiment, a connecting shaft 3045 is connected to the transmission disk 3041, as... Figure 13 As shown, the horizontal plate 3052 has a stepped hole for accommodating the connecting shaft 3045, and the transmission disc 3041 can rotate relative to the connecting shaft 3045. Furthermore, as... Figure 12 As shown, the outer side of the connecting shaft 3045 is provided with U-shaped grooves 30451 evenly distributed along the radial circumference, and the horizontal plate 3052 is provided with a sliding groove 30521 aligned with the U-shaped grooves 30451.

[0091] Furthermore, such as Figure 9 , Figure 12 , Figure 13 As shown, the U-shaped groove 30451 is aligned with the sliding groove 30521. Furthermore, as... Figure 14 As shown, the bottom of the support claw 303 is I-shaped, that is, the support claw 303 has opening slots on both sides that open outwards. The width of the opening slots is adapted to the thickness of the horizontal plate 3052. The stiffening plates between the opening slots are used to pass through the sliding groove 30521 and the U-shaped groove 30451 so that the support claw 303 can slide back and forth along the sliding groove 30521 and the U-shaped groove 30451.

[0092] In this embodiment, by setting the transmission disk 3041 and transmission component in the transmission unit 304, when the first driving part 301 drives the driving block 3042 to slide, the driving block 3042 drives the transmission disk 3041 to rotate, and each support claw 303 slides with its corresponding limiting groove 30411 to realize the switching action between the first state and the second state. Not only does it drive each support claw 303 to move closer or further apart through a single driving source, but it also ensures that each support claw 303 can slide relative to each other and move closer or further apart at the same time, improving the consistency of the gripper opening the lower lip of the dust cover 9, and preventing the dust cover 9 from popping open due to excessive force on one side.

[0093] In a specific embodiment, the transmission component includes a first rolling element 3043 rotatably disposed at the bottom of the transmission disk 3041, and a second rolling element 3044 disposed at the bottom of the support claw 303, the second rolling element 3044 being disposed within a limiting groove 30411. The first rolling element 3043 is rotatably connected to the bottom end of the transmission disk 3041 and is used to be placed within the groove 30421 of the aforementioned drive block 3042. The second rolling element 3044 is rotatably connected to the bottom of the support claw 303. When the second rolling element 3044 is disposed within the limiting groove 30411, the first driving part 301 drives the support claws 303 to retract or move away from each other.

[0094] In this embodiment, the first rolling element 3043 and the second rolling element 3044 can be deep groove ball bearings. The first rolling element 3043 or the second rolling element 3044 is fixed to its transmission disk 3041 or support claw 303 by bolts. This arrangement improves the transmission flexibility of the transmission unit 304 and avoids jamming. Alternatively, the first rolling element 3043 can be placed only at the bottom of the transmission disk 3041, and guide posts can be placed at the bottom of the support claw 303. Sliding of the support claw 303 can also be achieved by sliding the guide posts against the limiting groove 30411.

[0095] To facilitate setting the stroke of the support claw 303, a limiting part is provided on the base 1. The limiting part is used to limit the rotation angle of the transmission component. Figure 7 and Figure 8 As shown, a right mounting plate 3053 is provided on one side of the horizontal plate 3052. The right mounting plate 3053 is used to fix and connect the slide rail 3055 for guiding the sliding of the drive block 3042. A left mounting plate 3054 is provided on the other side of the horizontal plate 3052, which is used to connect the limiting part.

[0096] In this embodiment, by providing a limiting part on the base 1, the rotation angle of the transmission component is limited by the limiting part, thereby limiting the sliding stroke of the support claw 303 in the first state or the second state. Furthermore, by adjusting the position of the limiting part, it can be applied to the automatic installation of ball pin seats and dust covers 9 of different specifications, thereby improving the applicability of the dust cover assembly equipment.

[0097] Furthermore, the limiting part includes two limiting blocks 101 disposed opposite to each other on the base 1, and the transmission member is located between the two limiting blocks 101. The distance between the two limiting blocks 101 is adjustable. Figure 7 and Figure 8 As shown, the limiting block 101 is a long strip-shaped block structure, and both limiting blocks 101 are fixed to the left mounting plate 3054 by bolts.

[0098] like Figure 7As shown, the lower end of the transmission disc 3041 is also provided with a downward protruding stopper 105, which is limited between the two limiting blocks 101 when the transmission disc 3041 rotates. And the left mounting plate 3054 is provided with a long hole along the sliding direction of the driving block 3042, which can manually adjust the distance between the two transmission members when the fixing screws of the limiting blocks 101 are loosened.

[0099] Specifically, the supporting claw 303 includes a base 3031 slidingly arranged in the limiting groove 30411, and a supporting rod 3032 arranged on the top of the base 3031. The top of the supporting rod 3032 is provided with a hook body 30323 protruding away from the fixed part 201, which can be hooked on the dust cover 9 to limit the dust cover 9 from being separated from the supporting claw 303. As shown in Figure 14 And Figure 15 As shown, the base 3031 of the embodiment is arranged below the supporting rod 3032 and is bolted with the supporting rod 3032.

[0100] As shown in Figure 14 The base 3031 is shaped as a plate structure, the bottom of which is in the shape of an I-beam as described above, and is used to slide along the sliding groove 30521 on the horizontal plate 3052 and the U-shaped groove 30451. Therefore, the bottom of the base 3031 can also guide the sliding of the supporting claw 303. The upper part of the base 3031 is a straight plate connected to the I-beam-shaped bottom and vertically extends upward, the thickness of which is adapted to the through groove 202, and the straight plate can slide along the through groove 202 of the fixed seat 2. In this way, the upper and lower parts of the supporting claw 303 are guided by the fixed seat 2 and the horizontal plate 3052, which improves the stability of the supporting claw 303 when sliding.

[0101] As shown in Figure 15 The supporting rod 3032 is a rod body with a bend, including a vertical segment 30321, a bend segment 30322, and a hook body 30323 connected integrally. The thickness of the supporting rod 3032 of the embodiment is equal to the thickness of the straight plate, so as to facilitate the supporting claw 303 to enter the through groove 202 when falling, and provide space for placing the ball pin seat.

[0102] As shown in Figure 15 The vertical segment 30321 of the embodiment is connected to the side of the straight plate of the upper part of the base 3031, the bend segment 30322 is bent towards the center of each supporting claw 303, and the hook body 30323 is vertically arranged upward from the end of the bend segment 30322. And the side of the hook body 30323 close to the center of the fixed seat 2 is provided with a circular arc end, which is used to abut against the press-fitting rod 10.

[0103] In addition, on the opposite side of the arc end, i.e. the back of the hook body 30323, a protrusion 30324 is provided which protrudes outward from the hook body 30323. When the lower lip of the dust cover 9 is pressed on the hook body 30323, the protrusion 30324 can prevent the dust cover 9 from being disengaged when each support claw 303 is moved away from the dust cover 9. In addition, the outer diameter of the protrusion 30324 part of the four hook bodies 30323 should be smaller than the inner diameter of the lower lip of the dust cover 9. Specifically, the size of the hook body 30323 can be adjusted according to the size of the lower lip of the dust cover 9.

[0104] It should be noted that before the ball pin seat is pressed, the pressing rod 10 needs to be sleeved on the ball pin rod 8, and the dust cover 9 is sleeved on the upper part of the pressing rod 10. As shown in Figure 4 the upper part of the pressing rod 10 is conical, and the pressing member 402 has a conical pressing hole. When the pressing member 402 is pressed downward, the dust cover 9 moves downward through the pressing rod 10, and the pressing rod 10 can penetrate into the pressing hole, thereby preventing the ball pin rod 8 from rotating with the ball pin seat, and playing a guiding role for the dust cover 9 and positioning the ball pin seat.

[0105] In addition, the base body 1 is provided with a first guide part 5 for guiding the movement of the support claw unit, and the base body 1 is provided with a second guide part 6 for guiding the movement of the pressing member 402. As shown in Figures 1 to 5 the third driving part 401 of the embodiment is also arranged on the top of the base body 1, and the third driving part 401 is arranged on the side close to the front of the base body 1.

[0106] As shown in Figures 1 to 5 and Figure 10 the first guide part 5 of the embodiment includes a guide rail 601 connected to the front of the back plate 104, and a first linear bearing seat 602 arranged on the vertical plate 3051. The first linear bearing seat 602 can slide up and down along the guide rail 601, thereby ensuring that the lifting position of each support claw 303 on the lifting seat 305 remains accurate, and preventing the dust cover 9 from being pressed off due to deviation of the ball pin seat during pressing.

[0107] Further, as shown in Figures 1 to 5 the power output end of the third driving part 401 is connected to the pressing member 402, and the second guide part 6 includes a connecting plate 501 arranged on one side of the pressing member 402, and a guide shaft 502 arranged between the power output end of the second driving part 302 and the lifting seat 305. The connecting plate 501 is integrally formed with the pressing member 402, and has a via hole for accommodating the guide shaft 502. When the pressing member 402 is driven to move up and down by the third driving part 401, the connecting plate 501 and the guide shaft 502 form a sliding guide for the pressing member 402.

[0108] It should be noted that, as shown in Figures 1 to 2As shown, the lower end of the guide shaft 502 is provided with a cylindrical step column, and the vertical plate 3051 is formed with a reverse T-shaped groove 30421 matched with the step column. The guide shaft 502 moves up and down to drive the lifting seat 305 to move up and down, thereby driving the supporting claw 303 to move up and down. In this way, the function can be realized under the premise of facilitating disassembly. In addition, in order to prevent the lifting seat 305 from tilting when moving up and down, the guide rail 601 of the present embodiment is arranged at the positions of the two ends of the vertical plate 3051.

[0109] In addition, it is necessary to mention that, in order to ensure the axial position accuracy of the press-fitting part 402 and the supporting claw 303 when they are folded, as shown, the present embodiment is also provided with a second linear bearing seat 603 on the connecting plate 501, which is in sliding connection with the guide rail 601, thereby effectively ensuring the position of the press-fitting part 402 and the supporting claw 303 when they are lifted, and ensuring the press-fitting effect of the dustproof sleeve 9. Figures 1 to 5

[0110] As a preferred embodiment, the power output end of the second driving part 302 of the present embodiment is provided with a buffer 403 for buffering the press-fitting part 402. As shown, Figures 1 to 5 The buffer 403 is arranged at the lower part of the connecting plate 501, and in the present embodiment, the buffer 403 is a hydraulic buffer. As shown, Figure 4 , Figure 5 , Figure 10 As shown, the back plate 104 is connected with a limiting plate 106, and when the buffer 403 moves downward and abuts against the limiting plate 106, the buffer 403 forms a buffer for the press-fitting part 402, so as to prevent the press-fitting part 402 from damaging the dustproof sleeve 9 due to too high speed.

[0111] In order to further ensure that the buffer position can be adjusted, as shown in Figure 4 and Figure 5 , a long hole is arranged on the back plate 104 in the height direction, and the limiting block 101 can be adjusted up and down along the long hole, which not only can adjust the press-fitting effect of the dustproof sleeve 9 in time, but also improves the applicability of the equipment.

[0112] Based on the same design idea, the present embodiment also relates to a kind of assembling method of the above dustproof sleeve assembly equipment, and the assembling method of the dustproof sleeve 9 includes the following steps:

[0113] The dustproof sleeve 9 is sleeved on the ball pin, and the ball pin is assembled on the ball pin seat;

[0114] The ball pin seat is fixed in the fixed part 201 of the fixed seat 2;

[0115] The dustproof sleeve 9 is press-fitted to the supporting claw unit in the first state by using the press-fitting mechanism 4;

[0116] ​The first driving part 301 drives the transmission unit 304 to drive the support claw unit to switch to the second state, so as to open the dust cover 9;

[0117] The opened dust cover 9 is pressed and assembled to the ball pin seat by the pressing and assembling mechanism 4.

[0118] According to the dust cover assembling method, the dust cover 9 is assembled in the following process by using the dust cover assembling device:

[0119] As shown in the figure, Figures 1 to 10 the ball pin seat, the ball pin rod 8 and the pressing rod 10 are placed in the fixed part 201, and the dust cover 9 is sleeved on the pressing rod 10 at this time. The second driving part 302 is started to make the lifting seat 305 rise, and the transmission unit 304 and the support claw unit rise correspondingly. The support claws 303 pass through the through slot 202 and the sliding groove 30521 and protrude from the upper surface of the fixed seat 2.

[0120] Then, the first driving part 301 drives the driving block 3042 to slide along the front and back direction of the base 1, so as to drive the transmission disc 3041 to rotate, thereby driving the support claws 303 to fold. The hook bodies 30323 of the support claws 303 abut against the outer side of the pressing rod 10. The third driving part 401 is started, and the dust cover 9 located on the upper part of the pressing rod 10 is pressed downward to the top of the support claws 303 by the third driving part 401, so that the lower lip of the dust cover 9 is arranged on the outer side of the hook bodies 30323.

[0121] The first driving part 301 is started in the reverse direction to drive the transmission disc 3041, and the support claws 303 slide in the direction away from each other. The hook bodies 30323 hook the inner side of the lower lip of the dust cover 9, and the lower lip of the dust cover 9 is opened. The third driving part 401 is started, and the third driving part 401 drives the pressing and assembling body to continue to press downward. At the same time, the second driving part 302 drives the lifting seat 305 to descend, and the four support claws 303 move downward together with the pressing and assembling body 402. The opened dust cover is pressed and assembled on the ball pin seat, and the hook bodies 30323 are separated from the dust cover 9.

[0122] The dust cover assembling method of the embodiment is described above. By using the dust cover assembling device, the ball pin provided with the dust cover 9 is installed on the ball pin seat, the dust cover 9 is located above the ball pin seat, the ball pin seat is fixed, and then the dust cover 9 is pressed and assembled to the outer side of the support claw unit. After the dust cover 9 is opened, the dust cover 9 is pressed and assembled to the ball pin seat. By pressing and assembling in the above steps, the dust cover 9 can be pressed and assembled after being opened, and the pressing and assembling quality of the dust cover 9 is ensured.

[0123] The above only describes the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
