Description

Technical Field

[0001] The present application relates to the technical field of automotive stabilizer bars, and particularly to a method and device for quickly disassembling and assembling a bonding fixture for an automotive stabilizer bar bushing. Background Art

[0002] The stabilizer bar is a torsion bar spring made of spring steel, shaped like a "U", and horizontally arranged on the front and rear suspensions of the vehicle. In the middle of the bar body, it is hinged to the vehicle body or frame with a rubber bushing, and both ends are connected to the suspension guide arm through rubber pads or ball joint pins at the side wall ends. The function of the stabilizer bar is to prevent the vehicle body from experiencing excessive lateral roll during a turn, keep the vehicle body as balanced as possible, make the car drive smoothly during turning and bumpy roads, and improve the ride comfort.

[0003] Among them, the bushing is fixed to the stabilizer bar by being installed on the subframe of the suspension system through a fixing clip. During the operation of the stabilizer bar, the bushing provides support, buffering, vibration isolation, and noise reduction functions for the stabilizer bar. The processing flow of bushing bonding is: press-fitting - heating - pressure holding - disassembly and assembly. When press-fitting the bushing, a fixture is required. The fixture includes an upper die, a lower die, and two rotating pins. Among them, the two rotating pins are respectively rotatably connected to both ends of the lower die. After the upper die and the lower die are spliced, the upper die and the lower die are spliced and fixed by rotating the rotating pins and buckling them on the upper die. However, once the rotating pins are buckled on the upper die, they are very tight. When the fixture enters the disassembly and assembly process, the operator cannot manually disassemble and assemble it, and other disassembly and assembly tools are needed, resulting in low efficiency. Therefore, the present application proposes a new technical solution. Summary of the Invention

Detailed Description of the Embodiment

[0036] The following further describes the present application in detail Figures 1-4 with reference to the attached

[0037] The embodiment of the present application discloses a quick disassembling and assembling device for a bonding fixture of an automotive stabilizer bar bushing.

[0038] Refer to Figure 1 and Figure 2, since two bushings need to be bonded and pressed onto the stabilizer bar, it is necessary to disassemble the two jigs on the stabilizer bar synchronously. In this embodiment, the structure of the jig includes an upper die 81, a lower die 82, and two rotating pins 83. Among them, the two rotating pins 83 are respectively rotatably connected to both ends of the lower die 82. After splicing the upper die 81 to the lower die 82, by rotating the rotating pins 83 upward, they are buckled onto the protruding parts on both sides of the upper die 81, thereby buckling and fixing the upper die 81 and the lower die 82. At the same time, a die groove is pre-opened at the top of the upper die 81 and a die hole runs horizontally through the upper die 81. This application disassembles and assembles this type of jig.

[0039] Refer to Figure 1 and Figure 2 , the quick disassembly and assembly device for the bushing bonding jig of the automotive stabilizer bar includes a frame 1, a positioning mechanism 2, an execution mechanism 3, and a conveying mechanism 4. Among them, the frame 1 includes a machine table board 11, a machine body board 12, and a guide rail assembly. The machine table board 11 is used to support the entire disassembly and assembly device. There are two groups of machine body boards 12. One group is vertically fixed on the machine table board 11, and the other group is vertically connected to the guide rail assembly. Among them, there are two groups of guide rail assemblies (each group has two guide rails). One group is horizontally installed on the machine table board 11, and the sliding part of the guide rail assembly is connected to the bottom of one group of machine body boards 12, so that this group of machine body boards 12 can move horizontally. The frame 1 also includes a lead screw and a handwheel. The lead screw is installed on the machine table board 11, parallel to the guide rail assembly on the machine table board 11. The nut seat of the lead screw is fixedly connected to the horizontally movable machine body board 12, and the handwheel is installed at one end of the lead screw, so as to meet the universality requirements of the disassembly and assembly device and adapt to stabilizer bars of different lengths. The main bodies (two guide rails) of the other group of guide rail assemblies are respectively installed vertically on the two groups of machine body boards 12.

[0040] Refer to Figure 1 and Figure 2 , the positioning mechanism 2 includes a fixed seat 21 and a positioning rod 22. There are two groups of fixed seats 21, which are respectively installed on the two groups of machine body boards 12, and ensure the positioning of the jig during the disassembly and assembly process through a three-point positioning method. The positioning rod 22 is arranged on the machine body board 12 and has the ability to adjust in three spatial dimensions. Its function is to support the ends of different stabilizer bars through quick adjustment and improve stability.

[0041] There are two groups of execution mechanisms 3, which are respectively arranged on the two machine body boards 12 and are used to disassemble the two bushing jigs on the stabilizer bar. Among them, each group includes a separation component 31, a power unit 32, and a controller. The separation component 31 is respectively installed on the sliding parts of the guide rail assemblies on the two groups of machine body boards 12. The power unit 32 is installed on the top of the machine body board 12 and is used to drive the separation component 31 to move up and down along the guide rail assembly of the machine body board 12 and disassemble and separate the upper die 81 from the stabilizer bar. The controller is electrically connected to the separation component 31 and the power unit 32.

[0042] The conveying mechanism 4 is arranged on the machine table board 11 and on one side of the fixed body board 12. The operator can transfer the disassembled fixture to the press-fitting process through the conveying mechanism 4, improving the recycling rate of the fixture. In this embodiment, the conveying mechanism 4 can be a roller conveyor, and the discharge end of the roller conveyor extends towards the direction of the press-fitting process.

[0043] Through the above settings, place the bushing bonding fixture to be disassembled and assembled on the fixed seat 21, make the actuator 3 move vertically downward to the specified position, the separation component 31 contacts the surface of the upper die 81 of the fixture, and applies a force to the upper die 81 of the fixture, so that the originally tightly fitted upper die 81 and lower die 82 are separated. After that, the disassembled and assembled fixture flows back to the press-fitting process through the conveying mechanism 4, realizing the recycling of the fixture.

[0044] Regarding the three-point positioning method of the fixed seat 21, the description is as follows:

[0045] Refer to Figure 2 , the fixed seat 21 includes a lower base 211, a plurality of fixing blocks 212 and a pressing cylinder 213. The lower base 211 is horizontally arranged on the body board 12. There are three fixing blocks 212, which are distributed on the side of the lower die 82 and can abut against the side walls of the lower die 82 in three directions. The pressing cylinder 213 is fixedly installed on the lower base 211. In order to facilitate placing the fixture in the positioning area formed by the three fixing blocks 212, the output shaft of the pressing cylinder 213 is fixed to one of the fixing blocks 212, and the other two fixing blocks 212 are fixed to the lower base 211 by bolts.

[0046] Through the above settings, the fixture can be abutted against the fixing blocks 212 at two of the fixed positions, and then the movable fixing block 212 can be driven by the pressing cylinder 213 to abut tightly against the fixture, thus completing the positioning.

[0047] Refer to Figure 2 And Figure 3 , the separation component 31 includes an upper base 311, two air grippers 312, a mold separating cylinder 313 and a top mold cylinder 314. The upper base 311 is installed on the sliding part of the guide rail component on the body board 12. The power output end of the power unit 32 is connected to the top of the upper base 311, enabling the upper base 311 to move vertically up and down. In this embodiment, the power unit 32 can be a gas-liquid booster cylinder. The two air grippers 312 are respectively fixedly installed on both sides of the upper base 311, and the installation positions of the two air grippers 312 correspond to the positions of the two rotating pins 83 of the lower die 82. A vertical push rod is fixed to the action end of the air gripper 312.

[0048] In this embodiment, a ranging sensor is installed on the body of the power unit 32. The detection end of the ranging sensor faces downward and measures the distance between it and the lower base 211. When the distance value reaches the threshold, the descent stops. At this time, the air claw 312 is located at a position close to the rotating pin 83, and the push rod on the air claw 312 is inserted into the mold groove of the upper mold 81 (at this time, the rotating pin 83 is located outside the push rod). By controlling the movement of the air claw 312, the push rod is driven to push outward, applying a force to the rotating pin 83 to push the rotating pin 83 away from the protruding part of the upper mold 81.

[0049] The mold splitting cylinder 313 is fixed to the upper base 311. A mold splitting rod is fixed to the output shaft of the mold splitting cylinder 313. The moving direction of the mold splitting rod is perpendicular to the moving direction of the push rod of the air claw 312. The mold splitting cylinder 313 is used to drive the mold splitting rod to pass through the pre-opened mold hole of the upper mold 81, and the upper mold 81 can be pulled up by the reset of the power unit 32.

[0050] Due to the lateral thrust of the push rod, the rotating pin 83 will rotate obliquely downward and away from the upper mold 81. In order to ensure that the rotating pin 83 is completely separated from the protruding part of the upper mold 81, and at the same time the rotating pin 83 is not on the upward movement path of the upper mold 81 and does not hinder the upward movement of the upper mold 81, the top mold cylinder 314 is thus provided. The body of the top mold cylinder 314 is fixed to the body plate 12 and is located below the lower base 211. The output shaft of the top mold cylinder 314 faces upward and is fixed to the bottom of the lower base 211, and is used to jack up the lower base 211 upward, so that the whole fixture moves upward, enabling the push rod to completely push down the rotating pin 83.

[0051] Among them, the controller is electrically connected to the two air claws 312, the mold splitting cylinder 313 and the top mold cylinder 314 respectively. The controller is configured as follows:

[0052] 1) If a disassembly and assembly instruction triggered by the user is received, control the power unit 32 to drive the upper base 311 to move down to a preset position, control the two air claws 312 to execute the push and separation instruction, and control the top mold cylinder 314 to execute the instruction to move up the fixed seat 21;

[0053] It can be understood that the disassembly and assembly instruction can be a switch start button pre-installed on the frame 1, and the preset position is the one described above where the distance value is detected by the ranging sensor and stops when it meets the preset threshold. In this embodiment, it can be to first control the two air claws 312 to execute the push and separation instruction, and then control the top mold cylinder 314 to execute the instruction to move up the fixed seat 21 after 1 s.

[0054] 2) When the signals fed back after the air claws 312 and the top mold cylinder 314 have each executed the instruction are received, control the mold splitting cylinder 313 to execute the instruction to move the mold splitting rod;

[0055] 3) When receiving the signal feedback after the split mold cylinder 313 finishes executing the instruction, control the top mold cylinder 314 and the power unit 32 to reset.

[0056] 4) When receiving the signal feedback after the power unit 32 finishes resetting, control the split mold cylinder 313 to reset.

[0057] With the above settings, after the split mold cylinder 313 inserts the split mold rod into the mold hole of the upper mold, the power unit 32 resets, thereby moving the split mold cylinder 313 upward to reset, and then driving the upper mold to move upward, separating the upper mold from the lower mold. After the power unit 32 finishes resetting, the split mold cylinder 313 retracts the output shaft, pulls out the split mold rod from the mold hole of the upper mold, the operator catches the upper mold, then removes the lower mold from the fixed seat 21, places the upper mold and the lower mold on the conveying mechanism 4, and the conveying mechanism 4 conveys them to the pressing process.

[0058] Refer to Figure 1 , the specific structure description of the positioning rod 22 with the adjustment ability in three spatial dimensions is as follows:

[0059] The positioning rod 22 is connected with an adjustment assembly 5. The adjustment assembly 5 includes a first cross bar 51, a vertical rod 52, and a second cross bar 53. The first cross bar 51 is fixedly connected to the side wall of the fuselage plate 12 that can move horizontally. The length direction of the first cross bar 51 is set along the moving direction of the fuselage plate 12. The vertical rod 52 is slidably connected to the first cross bar 51 longitudinally. The second cross bar 53 is slidably connected to the vertical rod 52 horizontally. The length direction of the second cross bar 53 is perpendicular to the length direction of the first cross bar 51. The positioning rod 22 is slidably connected to the second cross bar 53 longitudinally. The upper end of the positioning rod 22 supports at the end of the stabilizing rod. Among them, the fixing methods between the first cross bar 51 and the vertical rod 52, the second cross bar 53 and the vertical rod 52, and the positioning rod 22 and the second cross bar 53 are all fixed by screwing, so that the position of the positioning rod 22 can be adjusted according to the positions of different ends of the stabilizing rod.

[0060] Refer to Figure 4 , in another embodiment of the present application, after the upper mold 81 is separated and taken out, the operator still needs to lift the support rod 6 to remove the lower mold 82 from the fixed seat 21. To improve efficiency, the following settings are made:

[0061] The fuselage plate 12 is provided with a support rod 6 for supporting the middle position of the stabilizing rod. In this embodiment, the support rod 6 can be arranged on any group of fuselage plates 12 and is located on the side wall facing the other group of fuselage plates 12, so that the support rod 6 can support the middle position of the stabilizing rod. The inside of the support rod 6 is hollow and the upper end is open. A vertical adjusting rod 61 is slidably inserted into the support rod 6 longitudinally. The upper end of the adjusting rod 61 extends out of the top opening of the support rod 6 and is fixed with a tray for supporting the stabilizing rod. The bottom of the adjusting rod 61 is fixed with a horizontal connecting rod 62. A strip-shaped groove communicating with its inner cavity is longitudinally formed on the side wall of the support rod 6, and the end of the connecting rod 62 extends out of the strip-shaped groove. A linkage assembly 7 is arranged between the extending end of the connecting rod 62 and the lower base 211. When the lower base 211 moves down and resets, it will drive the connecting rod 62 to move upward through the linkage assembly 7, so that the top of the adjusting rod 61 extends out of the opening end of the support rod 6 and moves upward, lifting the stabilizing rod upward by a certain height, separating the stabilizing rod from the lower die 82, which is convenient for the operator to directly take out the lower die 82 from the fixed seat 21, saving the operation steps of the operator picking up the stabilizing rod first and then removing the lower die 82, and improving the overall disassembly and assembly efficiency.

[0062] Referring to Figure 4 , the linkage assembly 7 includes an input rack 71, a gear 72, an output rack 73, a spring 74 and an electromagnet 75. The support rod 6 is provided with a bracket for supporting the input rack 71, the output rack 73 and the gear 72. Among them, the gear 72 is rotatably connected to the bracket through a bearing. The input rack 71 and the output rack 73 are slidably connected to the bracket longitudinally, and the gear 72 is located between the input rack 71 and the output rack 73 and meshes with each other. The spring 74 is located below the input rack 71, and one end of the spring 74 is fixed to the outer wall of the support rod 6 and the other end is fixed to the lower end of the input rack 71. The side wall of the output rack 73 is fixed to the extending end of the connecting rod 62.

[0063] The electromagnet 75 is installed on the side wall of the lower base 211, and the electromagnet 75 can be adsorbed on the side wall of the input rack 71 when energized. A gravity sensor is installed at the position where the lower base 211 is located at the placement position of the lower die 82. The electromagnet 75 and the gravity sensor are respectively electrically connected to the controller;

[0064] The controller is configured to:

[0065] When receiving the signal fed back by the top die cylinder 314 when it is ready to reset, control the electromagnet 75 to be energized until the preset power-off condition is met.

[0066] Through the above arrangement, when the top mold cylinder 314 lifts the lower base 211 upward, the stabilizing bar moves upward as a whole and separates from the top of the adjusting rod 61. When the output shaft of the top mold cylinder 314 is to move downward and reset, the electromagnet 75 is energized to adsorb the input rack 71. In the process of the top mold cylinder 314 driving the lower base 211 to move downward, the input rack 71 will be driven to move downward. Under the meshing action of the gear 72, the output rack 73 will move upward, thereby driving the adjusting rod 61 to be pushed upward through the connecting rod 62. At the same time, the lower base 211 drives the stabilizing bar to move downward as a whole, and the adjusting rod 61 gradually moves upward and contacts the rod part of the stabilizing bar, so that the position of the stabilizing bar is relatively fixed. The lower base 211 continues to move downward until the reset is completed. There is an operating space between the stabilizing bar and the lower mold 82 for the operator to take out the lower mold 82, thereby improving the overall efficiency.

[0067] The power outage conditions include:

[0068] Get the gravity data fed back by the gravity sensor;

[0069] When the gravity data is lower than a preset threshold, timing starts, and when the timing duration exceeds the preset waiting duration, the electromagnet 75 is controlled to be powered off.

[0070] It can be understood that the threshold value can be the total weight of the lower mold 82 and the stabilizer bar. When the gravity data fed back by the gravity sensor is lower than the threshold value, it means that the stabilizer bar is separated from the lower mold 82. At the same time, since it is also necessary to reserve time for the lower base 211 to return to its position and the operator to take the lower mold 82 and the stabilizer bar, the waiting time setting needs to include the time required for the above-mentioned operator to operate normally.

[0071] Through the above arrangement, after the operator takes out the lower mold 82 and places it on the conveying mechanism 4, the stabilizer bar is removed from the device. At this time, the electromagnet 75 is powered off, the magnetic force disappears, and the input rack 71 moves upward and resets under the elastic force of the spring 74. At the same time, the output rack 73 moves downward, causing the adjustment rod 61 to move downward and reset, ready to support the next stabilizer bar.

[0072] The embodiment of the present application also discloses a method for quickly disassembling and assembling a bonding fixture for an automobile stabilizer bar bushing.

[0073] A method for quickly disassembling and assembling a bonding fixture for a vehicle stabilizer bar bushing uses any of the above-mentioned devices for quickly disassembling and assembling a bonding fixture for a vehicle stabilizer bar bushing to disassemble and assemble the bushing fixture.

[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
