Description

Technical Field

[0001] The present invention relates to the technical field of assembly equipment, in particular to automobile parts assembly equipment. Background Art

[0002] The control arm, also known as the swing arm, is a core component of the vehicle's suspension system, primarily connecting the wheel knuckle to the vehicle frame. It elastically connects the wheel and vehicle body through a ball joint or bushing, transmitting various forces acting on the wheel to the vehicle body while ensuring the wheel follows a defined trajectory.

[0003] During the production and processing of the control arm, the bushing needs to be installed in the mounting hole on the surface of the control arm.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 1 and 2.

The first positioning portion 712 is used to control multiple groups of push plates 711 to be distributed in a ring shape with equal spacing on the surface of the positioning column 31. The first adjustment portion 713 is located in the positioning column 31 and is connected to the first positioning portion 712. The first adjustment portion 713 controls the multiple groups of push plates 711 to move back and forth synchronously toward the outside of the positioning column 31 by cooperating with the first positioning portion 712. The control arm positioning assembly 72 includes a cross column 721, a second positioning portion 722 The second adjusting portion 723 and the cross column 721 are provided with multiple groups. The second positioning portion 722 is located on the surface of the positioning column 31 and is connected to the cross column 721. The second positioning portion 722 is used to control the multiple groups of cross columns 721 to be distributed in a ring shape with equal intervals below the push plate 711. The second adjusting portion 723 is located in the positioning column 31 and is connected to the second positioning portion 722. The second adjusting portion 723 controls the multiple groups of cross columns 721 to move back and forth synchronously toward the outside of the positioning column 31 by cooperating with the second positioning portion 722.

[0028] When in use, the control arm body 5 is placed on the surface of the workbench 11, and the assembly seat 3 and the support seat 4 cooperate with each other to stably support the control arm body 5. At this time, the mounting hole 51 on the surface of the control arm body 5 is sleeved on the outside of the positioning column 31. During assembly, the bushing 6 is also sleeved on the outside of the positioning column 31 and placed on the upper surface of the mounting hole 51. The hydraulic cylinder 2 pushes the pushing column 21 to move vertically downward. When the pushing column 21 moves downward, the first adjusting portion 713 cooperates with the first positioning portion 712 to control multiple groups of push plates 711 to move synchronously toward the outside of the positioning column 31. The push plates 711 contact the inner wall of the bushing 6 and push the bushing 6 to move, so that the axis of the bushing 6 coincides with the axis of the positioning column 31. The second positioning portion 722 cooperates with the second adjusting portion 723 to control multiple groups of cross columns 721 to move synchronously toward the outside of the positioning column 31. Multiple groups of cross columns 721 can also adjust the position of the control arm body 5 and the mounting hole 51, so that the axis of the mounting hole 51 coincides with the axis of the positioning column 31. After the position of the bushing 6 and the mounting hole 51 is corrected, the first adjustment portion 713 cooperates with the first positioning portion 712 to control the multiple sets of push plates 711 to move in the opposite direction to their original positions. The second positioning portion 722 cooperates with the second adjustment portion 723 to control the multiple sets of crossbars 721 to move in the opposite direction to their original positions. The push post 21 continues to move downward, and the bottom end of the push post 21 presses the bushing 6, which can be easily assembled into the mounting hole 51.

[0029] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 As shown, as a preferred embodiment of the present invention, the first positioning portion 712 includes a plurality of groups of annularly distributed vertical grooves 7121 opened on the surface of the positioning column 31, and two groups of relatively distributed sliding blocks 7122 are slidably installed in the vertical groove 7121 along the vertical direction, and a push-pull rod 7123 is rotatably installed on the surface of the sliding block 7122, and the push-pull rod 7123 is rotatably connected to the push plate 711 at one end away from the sliding block 7122, and a fixed plate 7124 is fixedly installed in the middle of the vertical groove 7121, and a reset spring 7125 is fixedly installed on the surface of the fixed plate 7124, and the telescopic end of the reset spring 7125 is connected to the sliding block 7122.

[0030] The two groups of sliding blocks 7122 cooperate with the push-pull rod 7123 to stably support and position the push plate 711 in the vertical groove 7121. When the bushing 6 is placed to the outside of the positioning column 31 and the pushing column 21 moves downward, the first adjustment part 713 controls the two groups of sliding blocks 7122 to move relative to each other in the vertical groove 7121. The sliding blocks 7122 cooperate with the push-pull rod 7123 to conveniently push the push plate 711 to the outside of the vertical groove 7121. Multiple groups of push plates 711 move toward the outside of the positioning column 31 and contact the inner wall of the bushing 6. The push plate 711 can conveniently adjust the position of the bushing 6 so that the axis of the bushing 6 coincides with the axis of the positioning column 31. After the position of the bushing 6 is corrected, the first adjustment portion 713 releases the driving force on the sliding block 7122, and the return spring 7125 pushes the two sets of sliding blocks 7122 to move back to their original positions in the vertical slot 7121. The sliding blocks 7122 cooperate with the push-pull rod 7123 to control the multiple sets of push plates 711 to move back to the vertical slot 7121. When the pushing column 21 squeezes the bushing 6, it effectively prevents the push plates 711 from interfering with the entire squeezing process.

[0031] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown in a preferred embodiment of the present invention, the first adjusting portion 713 includes a vertical hole 7131 downwardly opened on the surface of the positioning column 31, a support spring 7135 is fixedly installed at the bottom of the vertical hole 7131, a second magnetic block 7134 is fixedly installed at the telescopic end of the support spring 7135, a first magnetic block 7132 is placed on the surface of the second magnetic block 7134, a first through hole 7133 is opened on the surface of the first magnetic block 7132, and a first wire groove extending into the vertical groove 7121 is opened outwardly on the side wall of the vertical hole 7131 7136, a first pulling rope 7137 is fixedly installed on the surface of the sliding block 7122, and the end of the first pulling rope 7137 away from the sliding block 7122 passes through the first wire groove 7136 and extends into the vertical hole 7131 and is connected to the first magnetic block 7132, and a top hole 7138 is opened upward at the bottom end of the pushing column 21, and an extrusion spring 7139 is fixedly installed in the top hole 7138, and a cushion block 71310 is fixedly installed on the telescopic end of the extrusion spring 7139, and a rough pressure rod 71311 is provided on the bottom wall of the cushion block 71310.

[0032] During assembly, the hydraulic cylinder 2 controls the pushing column 21 to move vertically downward, and the pushing column 21 drives the rough pressure rod 71311 to move downward synchronously. The rough pressure rod 71311 is inserted into the vertical hole 7131 and further passes through the first through hole 7133 to apply thrust to the second magnetic block 7134. The rough pressure rod 71311 pushes the second magnetic block 7134 to move downward in the vertical hole 7131. The second magnetic block 7134 drives the first magnetic block 7132 to move downward synchronously through the magnetic force. The first magnetic block 7132 cooperates with the first pulling rope 7137 to pull the two groups of sliding blocks 7122 to move relative to each other in the vertical slot 7121. After the two groups of sliding blocks 7122 move to the extreme position in the vertical slot 7121, the push plate 711 and the position of the bushing 6 are corrected, and the pulling force of the first pulling rope 7137 on the first magnetic block 7132 is greater than the magnetic attraction between the second magnetic block 7134 and the first magnetic block 7132. At this time, the second magnetic block 7134 and the first magnetic block 7132 are separated from each other, and the driving force on the sliding block 7122 is released. The reset spring 7125 pushes the two groups of sliding blocks 7122 to move in the opposite direction to the original position in the vertical slot 7121.

[0033] like Figure 4 、 Figure 5 、 Figure 8 As shown, as a preferred embodiment of the present invention, the second positioning portion 722 includes a plurality of groups of circularly distributed transverse holes 7221 opened on the surface of the positioning column 31, the transverse column 721 is slidably installed in the transverse hole 7221, the side wall of the transverse hole 7221 is provided with a guide groove 7222, and the surface of the transverse column 721 is fixedly installed with a guide plate 7223 slidingly connected to the guide groove 7222, and a guide spring 7224 is fixedly installed in the guide groove 7222, and the telescopic end of the guide spring 7224 is connected to the guide plate 7223.

[0034] The guide spring 7224 applies a thrust to the guide plate 7223, which is located at one end of the guide groove 7222 near the center of the positioning column 31. The guide plate 7223 positions the cross column 721, and the cross column 721 is now entirely within the cross hole 7221. When the push column 21 moves downward, the second adjustment portion 723 applies a pulling force to the multiple groups of cross columns 721, and the multiple groups of cross columns 721 move synchronously toward the outside of the positioning column 31. The multiple groups of cross columns 721 contact the mounting holes 51. During the movement, the cross columns 721 adjust the position of the mounting holes 51 so that the axis of the mounting holes 51 coincides with the axis of the positioning column 31. After the position of the mounting holes 51 is corrected, the second adjustment portion 723 releases the driving force on the cross columns 721, and the guide spring 7224 cooperates with the guide plate 7223 to push the cross columns 721 to move in the opposite direction and into the cross hole 7221. During the assembly of the bushing 6 , the cross column 721 can be effectively prevented from interfering with the entire assembly process.

[0035] like Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 As shown in FIG. 7 , as a preferred embodiment of the present invention, the second adjustment portion 723 includes a vertical cavity 7231 opened inside the positioning column 31 and located directly below the vertical hole 7131. A control spring 7232 is fixedly installed at the bottom of the vertical cavity 7231. A third magnetic block 7233 is fixedly installed at the telescopic end of the control spring 7232. A fourth magnetic block 7234 is placed on the surface of the third magnetic block 7233. A second through hole 7235 is opened on the surface of the fourth magnetic block 7234. A through hole 7235 is opened on the side wall of the vertical cavity 7231 and connected to the horizontal hole 7221. The second wire groove 7236 is connected to the horizontal column 721, and a second pulling rope 7237 is fixedly installed at one end of the horizontal column 721 facing the center of the positioning column 31. The second pulling rope 7237 passes through the second wire groove 7236 and extends into the vertical cavity 7231 and is connected to the fourth magnetic block 7234. The bottom end of the vertical hole 7131 is downwardly provided with a vertical connecting hole 7238 connected to the vertical cavity 7231, and a fine hole 7239 is provided on the surface of the second magnetic block 7134. The bottom end of the coarse pressure rod 71311 is fixedly provided with a fine pressure rod 72310 that cooperates with the fine hole 7239.

[0036] The hydraulic cylinder 2 controls the pushing column 21 to move vertically downward, and the pushing column 21 drives the coarse pressure rod 71311 and the thin pressure rod 72310 to move downward synchronously. The thin pressure rod 72310 passes through the thin hole 7239 and the vertical connecting hole 7238 and then moves into the vertical cavity 7231. The thin pressure rod 72310 moves downward in the vertical cavity 7231 and then passes through the second through hole 7235 to apply a thrust to the third magnetic block 7233. The third magnetic block 7233 moves downward in the vertical cavity 7231. The third magnetic block 7233 drives the fourth magnetic block 7234 to move downward synchronously in the vertical cavity 7231 through magnetic attraction force. The fourth magnetic block 7234 cooperates with the second pulling rope 7237 to pull the horizontal column 721 in the horizontal hole 7221 toward the outside of the positioning column 31. After the position of the mounting hole 51 is corrected, the pulling force of the second pulling rope 7237 on the fourth magnetic block 7234 is greater than the magnetic attraction between the third magnetic block 7233 and the fourth magnetic block 7234. At this time, the fourth magnetic block 7234 and the third magnetic block 7233 are separated from each other, and the guide spring 7224 and the guide plate 7223 cooperate with each other to push the horizontal column 721 as a whole to move in the opposite direction into the horizontal hole 7221.

[0037] like Figure 9 As shown, as a preferred embodiment of the present invention, a threaded hole 8 is provided on the bottom wall of the cushion block 71310 , and a threaded seat 9 that cooperates with the threaded hole 8 is fixedly installed on the top of the rough pressure rod 71311 .

[0038] Through the cooperation between the threaded hole 8 and the threaded seat 9, the thick pressure rod 71311 and the thin pressure rod 72310 can be easily installed and disassembled on the surface of the pad 71310.

[0039] As a preferred embodiment of the present invention, a protection wheel (not shown) is respectively provided in the first wire groove 7136 and the second wire groove 7236. The protection wheel can effectively reduce the wear of the second pulling rope 7237 and the first pulling rope 7137.

[0040] The working principle of the present invention is: when in use, the control arm body 5 is placed on the surface of the workbench 11, and the assembly seat 3 and the support seat 4 cooperate with each other to stably support the control arm body 5. At this time, the mounting hole 51 on the surface of the control arm body 5 is sleeved on the outside of the positioning column 31. During assembly, the bushing 6 is also sleeved on the outside of the positioning column 31 and placed on the upper surface of the mounting hole 51. The hydraulic cylinder 2 pushes the pushing column 21 to move vertically downward, and the pushing column 21 drives the rough pressure rod 71311 to move downward synchronously. The rough pressure rod 71311 is inserted into the vertical hole 7131 and further passes through the first through hole 7133 to apply thrust to the second magnetic block 7134. The rough pressure rod 71311 pushes the second magnetic block 7134 to move downward in the vertical hole 7131. The second magnetic block 7134 drives the first magnetic block 7132 to move downward synchronously through the magnetic force. The first magnetic block 7132 cooperates with the first pulling rope 7137 to pull the two sets of sliding blocks 7122 to move relative to each other in the vertical slot 7121. The sliding block 7122 cooperates with the push-pull rod 7123 to conveniently push the push plate 711 to the outside of the vertical slot 7121. Multiple groups of push plates 711 move toward the outside of the positioning column 31 and contact the inner wall of the bushing 6. The push plates 711 can conveniently adjust the position of the bushing 6 so that the axis of the bushing 6 coincides with the axis of the positioning column 31. After the position of the bushing 6 is corrected, the pulling force of the first pulling rope 7137 on the first magnetic block 7132 is greater than the magnetic attraction between the second magnetic block 7134 and the first magnetic block 7132. At this time, the second magnetic block 7134 and the first magnetic block 7132 separate from each other, and the driving force on the sliding block 7122 is released. The return spring 7125 pushes the two groups of sliding blocks 7122 to move back to their original positions in the vertical slot 7121.

[0041] The pushing column 21 drives the coarse pressure rod 71311 and the thin pressure rod 72310 to move downward synchronously. The thin pressure rod 72310 passes through the thin hole 7239 and the vertical connecting hole 7238 and then moves into the vertical cavity 7231. The thin pressure rod 72310 moves downward in the vertical cavity 7231 and then passes through the second through hole 7235 to apply a thrust to the third magnetic block 7233. The third magnetic block 7233 moves downward in the vertical cavity 7231. The third magnetic block 7233 drives the fourth magnetic block 7234 to move downward synchronously in the vertical cavity 7231 through magnetic attraction. The fourth magnetic block 7234 cooperates with the second pulling rope 7237 to pull the horizontal column 721 to move toward the outside of the positioning column 31 in the horizontal hole 7221. Multiple groups of cross columns 721 are in contact with the mounting holes 51. The cross columns 721 adjust the position of the mounting holes 51 during the movement so that the axis of the mounting holes 51 coincides with the axis of the positioning column 31. After the position of the mounting holes 51 is corrected, the pulling force of the second pulling rope 7237 on the fourth magnetic block 7234 is greater than the magnetic attraction between the third magnetic block 7233 and the fourth magnetic block 7234. At this time, the fourth magnetic block 7234 and the third magnetic block 7233 are separated from each other, and the guide spring 7224 and the guide plate 7223 cooperate with each other to push the cross column 721 as a whole to move in the opposite direction into the cross hole 7221.

[0042] After the position of the bushing 6 and the mounting hole 51 is corrected, the multiple push plates 711 are moved back to their original positions, and the multiple cross posts 721 are moved back to their original positions simultaneously. The push posts 21 continue to move downward, and the bottom of the push posts 21 presses the bushing 6, which can be easily assembled into the mounting hole 51.

[0043] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
