Description

Technical Field

[0001] The invention belongs to the technical field of automobile shock absorber assembly, and in particular relates to a bushing assembly device for an automobile shock absorber. Background Art

[0002] The automobile shock absorber is actually a vibration damper. The middle of the shock absorber is made of a metal block (connecting sheet metal) and its two ends are connected by a rubber structure. The shock absorber is installed on the body pipeline to buffer and reduce vibration. Due to the beneficial effects of the shock absorber, it is not only used in the suspension of the car, but also in other locations, such as in the cab, seat, steering wheel, etc. It can also be used as a buffer on the vehicle bumper.

[0003] At present, manual assembly is usually used when assembling the rubber parts of the shock absorber and the connecting sheet metal. Before assembly, lubricant is first applied to the rubber parts, and then the rubber parts are pressed into the mounting holes of the connecting sheet metal parts manually or with auxiliary tools, and then the rubber parts are completely turned out of the mounting holes through the shaping tool. Due to manual assembly, the assembly efficiency is low and the assembly quality cannot be guaranteed; and the rubber parts are prone to aging and deterioration under the action of lubricants. When there is too much lubricant, it will also affect the pull-out force, thereby affecting subsequent assembly. Summary of the invention

[0050] Furthermore, the support frame 1 includes a base 14, a first fixed plate 11 and a second fixed plate 12 from bottom to top, and also includes support rods 13 connected to both ends of the first fixed plate 11 and the second fixed plate 12.

The two first support seats 23 are located in the same horizontal direction which is parallel to the length direction of the second support plate 22, and the two first support seats 23 are used to place a connecting member 102 together; the two second support seats 24 are located on both sides of the connecting member 102, and each second support seat 24 is used to place a bushing 101. In this embodiment, one end of a second support seat 24 on one side of the connecting member 102 is flush with one end of the first support seat 23, and a fixing rod is fixedly arranged at both ends of each second support seat 24, and the two fixing rods on a second support seat 24 are used to fix the position of a bushing 101 together to prevent it from falling.

[0052] Furthermore, if Figure 1 and Figure 2 As shown, the first moving mechanism and the rotating mechanism 3 are both connected to the supporting mechanism 2, the first moving mechanism is used to drive the supporting mechanism 2 to move back and forth along the width direction of the second supporting plate 22, and the rotating mechanism 3 is used to drive the supporting mechanism 2 to rotate.

The rotating shaft is located inside the shell 31 and passes through the third support plate 911, so that the first support plate 21 and the second support plate 22 can rotate around the axis of the rotating shaft relative to the third support plate 911 under the driving action of the fourth driver 32; in addition, under the driving action of the third driver 914, the third support plate 911 can move back and forth along the length direction of the first slide rail 913, thereby driving the support mechanism 2 as a whole to move back and forth along the length direction of the first slide rail 913.

[0053] Furthermore, the fixing mechanism 5 located on one side of the supporting mechanism 2 is used to fix the position of the connecting member 102 placed on the first supporting seat 23, such as Figure 3 As shown, the fixing mechanism 5 includes a fixing shaft 51 and a driver fixedly connected to the fixing shaft 51. The driver in the fixing mechanism 5 is used to drive the fixing shaft 51 to move back and forth in a direction parallel to the length direction of the connecting member 102, so that the fixing shaft 51 can move in a direction close to or away from the mounting hole 103 to be inserted into or removed from the mounting hole 103. Specifically, the fixing shaft 51 in this embodiment includes a conical head close to one end of the connecting member 102, the outer diameter of the conical head gradually increases from the end close to the connecting member 102 to the other end, and the outer diameter of the end of the conical head away from the connecting member 102 is equal to or greater than the diameter of the mounting hole 103 of the connecting member 102. The conical head of the fixing shaft 51 can be inserted into a corresponding mounting hole 103 of the connecting member 102 to play the role of alignment, positioning and fixing.

[0054] In addition, the push head mechanism 6 located on the other side of the support mechanism 2 is used to push one end of the bushing 101 into the interior of the bushing 101, and with the assistance of the first clamping mechanism 7 and the second moving mechanism, one end of the bushing 101 is flush with the mounting hole 103 of the connector 102. When the push head retracts, the part of the bushing 101 squeezed into the interior is pulled out and turned over to just clamp the connector 102, thereby realizing that one end of the bushing 101 is tightly assembled into the mounting hole 103 at one end of the connector 102. Specifically, as Figure 3 and Figure 4 As shown, the push head mechanism 6 of this embodiment includes a push head and a driver fixedly connected to the push head, and the driver in the push head mechanism 6 is used to drive the push head to move back and forth along a direction parallel to the length direction of the connecting member 102 to cooperate with the bushing 101. The push head includes a shaft 61 and a head 62, one end of the shaft 61 is connected to the driver, and the other end of the shaft 61 (the end close to the connecting member 102) is fixedly connected to the head 62, and the outer diameter of the shaft 61 and the outer diameter of the head 62 of the push head are both smaller than the diameter of the mounting hole 103 so that the push head can pass through the mounting hole 103; and the outer diameter of the head 62 is slightly larger than the outer diameter of the end of the bushing 101 close to the push head mechanism 6, so as to ensure that the push head can squeeze one end of the bushing 101 into the inside of the bushing 101 under the action of the driver and the second clamping jaw mechanism 8, and at the same time ensure that when the push head retracts, the head 62 of the push head can take the one end of the bushing 101 squeezed into the inside of the bushing 101 out of the bushing 101. In order to ensure that the head 62 of the pusher head can better wrap one end of the sleeve 101, thereby facilitating pushing and squeezing the sleeve 101, the head 62 of the pusher head is provided to include a plurality of evenly spaced extension pieces 621, and a side of each extension piece 621 close to the connecting piece 102 is arranged to be arc-shaped, and the plurality of arc-shaped surfaces of the plurality of extension pieces 621 cooperate with each other to enclose and form a portion for wrapping one end of the sleeve 101 squeezed by the second clamping mechanism 8.

[0055] In this embodiment, when the bushing 101 is assembled, the axis center line of the fixed shaft 51, the axis center line of the push head and the center of the mounting holes 103 at both ends of a connecting member 102 are all located on the same horizontal line.

[0056] Furthermore, the two positioning mechanisms 4 symmetrically arranged on both sides of the support mechanism 2 can ensure that the support mechanism 2 moves into position under the action of the first moving mechanism and fix the support mechanism 2 at the current position. Figure 1 and Figure 2As shown, each positioning mechanism 4 includes a fixing seat 41, a fifth driver 42 connected to the fixing seat 41, and a latch 43 connected to the fifth driver 42.

The latch 43 is located below the fifth driver 42, and one end of the latch 43 connected to the fifth driver 42 is located above the first support plate 21; the fifth driver 42 is used to drive the latch 43 to move up and down in the vertical direction (parallel to the direction of the support rod 13). In this embodiment, two plug holes 211 are respectively provided at both ends of the first support plate 21, and the plug holes 211 are used for inserting the latch 43. Before the bushing 101 is assembled, the latch 43 is inserted into a corresponding plug hole 211 on the first support plate 21 to ensure that the support mechanism 2 moves into place, which is convenient for the subsequent alignment of the fixing mechanism 5 and the push head mechanism 6 with the mounting hole 103 of the connecting member 102; at the same time, the support mechanism 2 can also be fixed to prevent it from moving or shaking during the assembly process.

[0057] Furthermore, the first clamping mechanism 7 is used to clamp the bushing 101 on the supporting mechanism 2. Figures 5 to 9 As shown, the first clamping mechanism 7 includes a top plate 71, a first driver 75, a first clamping plate 72 and a second clamping plate 73, a first connecting plate 74 slidingly connected to the first clamping plate 72, and a first clamping assembly arranged on the first clamping plate 72, wherein the first clamping plate 72 is fixedly connected to the second clamping plate 73, the first connecting plate 74 is fixedly connected to the first driver 75, and the first driver 75 is used to drive the first connecting plate 74 to move up and down along the length direction of the first clamping plate 72 (parallel to the direction of the support rod 13) to approach or move away from the support mechanism 2.

[0058] Specifically, Figure 8As shown, the first clamping jaw assembly includes two first connecting rods 76 and two first clamping jaws 77. The first connecting plate 74, the first connecting rod 76 and the first clamping jaws 77 are all located between the first clamping plate 72 and the second clamping plate 73. The two first connecting rods 76 are arranged at the bottom end of the first clamping plate 72, and the first clamping jaws 77 are arranged at one end of the first connecting rod 76 away from the first connecting plate 74.

The first connecting rod 76 is also rotatably connected to the first clamping plate 72. In addition, two grooves 721 parallel to the width direction of the first clamping plate 72 are provided at the bottom of the first clamping plate 72 corresponding to the two first clamping jaws 77, so that the first clamping jaws 77 can move in the grooves 721 along the length direction thereof, and the first driver 75 drives the first connecting plate 74 to move up and down, thereby driving the two first connecting rods 76 to rotate to approach or move away from each other, so as to drive the two first clamping jaws 77 to move in the grooves 721 in the direction of approaching or moving away from each other, and when approaching each other, the bushing 101 can be clamped between the two first clamping jaws 77; when the bushing 101 needs to be released, under the action of the first driver 75, the two first clamping jaws 77 move in the direction of moving away from each other. In this embodiment, when the first driver 75 drives the first connecting plate 74 to move upward, the two first clamping jaws 77 approach each other to clamp the bushing 101; when the first driver 75 drives the first connecting plate 74 to move downward, the two first clamping jaws 77 move away from each other to release the bushing 101.

[0059] The second moving mechanism is used to drive the first clamping mechanism 7 to move horizontally and vertically. Figures 5 to 7 As shown, the second moving mechanism includes a second slider 921 fixedly disposed at both ends of the top surface of the top plate 71, a second slide rail 922 slidably connected to the second slider 921, a third fixed plate 923 fixedly connected to the second slide rail 922, a third slider 924 fixedly disposed at both ends of the top surface of the third fixed plate 923, and a third slide rail 925 slidably connected to the third slider 924.

[0060] The second moving mechanism also includes a sixth driver 926 fixedly connected to the top plate 71, a seventh driver 927 fixedly connected to the third fixed plate 923, and an eighth driver 928 connected to both the first fixed plate 11 and the second fixed plate 12 of the support frame 1. The sixth driver 926 is used to drive the top plate 71 to move along the length direction of the second slide rail 922, and the seventh driver 927 is used to drive the third fixed plate 923 to move along the length direction of the third slide rail 925; the outer shell of the eighth driver 928 is fixedly connected to the second fixed plate 12, and the driving shaft of the eighth driver 928 is fixedly connected to the first fixed plate 11 to drive the first fixed plate 11 to move along the length direction of the support rod 13.

[0061] In this embodiment, in order to indicate and limit the moving position of the third fixed plate 923, the second moving mechanism also includes a vertical plate 929 fixedly arranged on the top surface of the third fixed plate 923 and two sensors 930 fixedly arranged on the top surface of the first fixed plate 11. In addition, a through slot 112 penetrating the thickness direction of the first fixed plate 11 is provided at a position corresponding to the vertical plate 929 on the first fixed plate 11 for the vertical plate 929 to pass through. The vertical plate 929 is perpendicular to the through slot 112 and the third fixed plate 923, and the length of the through slot 112 is greater than the width of the vertical plate 929. The two sensors 930 are respectively located at the two ends of the through slot 112. When the third fixed plate 923 drives the vertical plate 929 to move back and forth and touches a corresponding sensor 930, the vertical plate 929 cannot continue to move in this direction.

[0062] Furthermore, the second clamping mechanism 8 is used to squeeze the bushing 101 clamped by the first clamping mechanism 7. Figure 1 , Figures 10 to 12As shown, the second clamping jaw mechanism 8 comprises a first mounting plate 81, a third clamping plate 82 fixedly connected to the first mounting plate 81, a fourth clamping plate 83 fixedly connected to the third clamping plate 82, a second clamping jaw assembly disposed on the fourth clamping plate 83, a second connecting plate 84 slidably connected to the fourth clamping plate 83, and a second driver 85 fixedly connected to the second connecting plate 84.

One end of the second connecting rod 87 is rotatably connected to the second connecting plate 84, and the other end of the second connecting rod 87 is rotatably connected to the second clamping jaw 88, and the second clamping jaw 88 is also rotatably connected to the fourth clamping plate 83; the bottom end of the fourth clamping plate 83 is also provided with a clamping hole 831 for one end of the bushing 101 to pass through, the protrusion 86 is located above the clamping hole 831, and the two second clamping jaws 88 are located on both sides of the clamping hole 831, so that the second clamping jaw 88 and the protrusion 86 can cooperate to squeeze the bushing 101. The second driver 85 is used to drive the second connecting plate 84 to move up and down along the length direction of the first mounting plate 81, thereby driving the two second connecting rods 87 to rotate to approach or move away from each other, so as to drive the two second clamping jaws 88 to approach or move away from each other. In this embodiment, when the second driver 85 drives the second connecting plate 84 to move downward (in the direction close to the clamping hole 831), the protrusion 86 gradually approaches the clamping hole 831, and the two second clamping jaws 88 also approach each other, so that the protrusion 86 and the two second clamping jaws 88 simultaneously approach each other to squeeze one end of the bushing 101 located in the clamping hole 831, so that the push head mechanism 6 can squeeze one end of the bushing 101 into the interior of the bushing 101 through the push head and flatten it to be flush with the end surface of the mounting hole 103, and finally, through the mutual cooperation of the push head mechanism 6 and the first clamping jaw mechanism 7, the part of the bushing 101 squeezed into its interior is flanged out, and the connecting member 102 is clamped to ensure a tight fit between the bushing 101 and the connecting member 102.

[0063] The third moving mechanism is used to drive the second clamping mechanism 8 to move up and down in the vertical direction. Specifically, Fig.10 and Fig.11As shown, the third moving mechanism includes a second mounting plate 931 fixedly connected to the top surface of the first fixing plate 11, a fourth slider 932 fixedly arranged on both sides of a side of the second mounting plate 931 close to the first mounting plate 81, a fourth slide rail 933 fixedly arranged on both sides of a side of the first mounting plate 81 close to the second clamping claw 88, and a ninth driver 934 fixedly connected to the top of the first mounting plate 81. The fourth slider 932 is slidably connected to the fourth slide rail 933, the second mounting plate 931 is parallel to the first mounting plate 81, and the third clamping plate 82 and the fourth clamping plate 83 are located between the first mounting plate 81 and the second mounting plate 931, and the ninth driver 934 is used to drive the first mounting plate 81 to move up and down along the length direction of the fourth slide rail 933, thereby driving the second clamping claw mechanism 8 to move up and down along the length direction of the fourth slide rail 933 to approach or move away from the support mechanism 2.

[0064] The working process of the bushing assembly device of the automobile shock absorber in this embodiment is briefly described below:

[0065] First, manually place the connecting piece 102 on the first support seat 23 and the two bushings 101 on the second support seat 24, and then drive the supporting mechanism 2 to move to correspond to the positioning mechanism 4 under the action of the first moving mechanism, so that the pin 43 of the positioning mechanism 4 is just inserted into the socket 211 on the first support plate 21, and the driver of the fixing mechanism 5 drives the fixing shaft 51 to extend toward the mounting hole 103 of the connecting piece 102 to be inserted into a corresponding mounting hole 103, so that the fixing mechanism 5 fixes the connecting piece 102. Under the action of the eighth driver 928, the first clamping jaw assembly is driven to descend to gradually approach the bushing 101 on the supporting mechanism 2 (a bushing 101 away from the fixing mechanism 5). When approaching the bushing 101, the first driver 75 works to make the first clamping jaw assembly grab the bushing 101; then under the action of the eighth driver 928, the first clamping jaw assembly is driven to rise and under the action of the seventh driver 927, the first clamping jaw assembly is driven to move above one end of the connecting member 102, and then under the action of the eighth driver 928, the first clamping jaw assembly is driven to descend to approach one end of the connecting member 102. Under the action of the ninth driver 934, the second clamping jaw assembly is driven to descend to approach the bushing 101 clamped by the first clamping jaw assembly, and then under the action of the second driver 85, the second clamping jaw assembly is driven to clamp and squeeze one end of the bushing 101.

[0066] Next, the driver of the push head mechanism 6 drives the push head to extend toward the bushing 101 squeezed by the second clamping assembly and pass through the mounting hole 103 at one end of the connecting piece 102. The moving push head continuously pushes and squeezes one end of the bushing 101 so that the end enters the interior of the bushing 101. Then, under the action of the second driver 85, the second clamping jaw assembly releases the bushing 101 and under the action of the ninth driver 934, the second clamping jaw assembly is driven to rise to make way.

[0067] Under the joint action of the sixth driver 926 and the driver of the push head mechanism 6, the bushing 101 is driven to move to a position flush with the mounting hole 103 at one end of the connecting member 102 (the end away from the fixing mechanism 5). At this time, the driver of the push head mechanism 6 continues to drive the push head to retract, and the first clamping jaw assembly and the bushing 101 do not move. When the push head retreats, the head 62 of the push head will gradually pull out the end of the bushing 101 located inside it, so that it will be flanged out and just catch the mounting hole 103 of the connecting member 102, so that the bushing 101 is assembled to the connecting member 102. At this point, the assembly of the bushing 101 on a mounting hole 103 at one end of the connecting member 102 is completed.

[0068] Then, under the action of the fourth driver 32, the rotating shaft is driven to rotate to drive the supporting mechanism 2 to rotate 180° as a whole, so as to realize the reversal of the two second supporting seats 24 on the second supporting plate 22, and rotate a second supporting seat 24 away from the pushing head mechanism 6 before rotation to a position close to the pushing head mechanism 6, and then complete the assembly of another bushing 101 according to the above steps, and finally, respectively assemble the two bushings 101 into the two mounting holes 103 of the connecting piece 102 to complete the assembly.

They cannot be used to limit the protection scope of the present invention.
