Description

Technical Field

[0001] This invention relates to the field of stabilizer bar bushing vulcanization equipment, and more particularly to a stabilizer bar clamp operating device. Background Technology

[0002] A stabilizer bar is an auxiliary elastic element in a car suspension. Its main function is to prevent excessive lateral roll of the vehicle body during cornering, thus maintaining vehicle balance as much as possible. Bushings and stabilizer bars are mounted on the auxiliary frame of the suspension system via clamps. When the stabilizer bar is in operation, the bushings provide support, cushioning, vibration isolation, and noise reduction. The bushing manufacturing process is: press-fitting - heating - pressure holding - disassembly / removal. Most domestic manufacturers use hydraulic press-fitting machines in the first stage—press-fitting the bushings—and hydraulic disassembly / removal machines in the final stage—disassembly / removal.

[0003] Hydraulic press fitting machines and disassembly / removal machines have the following disadvantages:

[0004] 1. Prone to oil leakage, resulting in reduced efficiency.

[0005] 2. The oil is flammable and poses a risk of explosion.

[0006] 3. Maintenance is not simple and requires professional personnel. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned problems in the prior art and to provide a stabilizer bar clamping operating device.

[0008] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

Two symmetrical vulcanizing clamp positioning supports are mounted on each platform. A support rod is suspended from each gantry frame via a balancer assembly. Two pneumatic manipulators capable of moving along the long axis of each support rod are mounted at the bottom of each support rod. A pneumatic manipulator is positioned directly above each vulcanizing clamp positioning support. The two pneumatic manipulators mounted on the bottom of one of the support rods have two symmetrical pressing jaws hinged to their bottoms. The first head of each pressing jaw has an arc-shaped inner groove. The two pneumatic manipulators mounted on the bottom of the other support rod have two symmetrical disassembly jaws hinged to their bottoms. The first head of each disassembly jaw has an arc-shaped outer groove.

[0010] The balancer assembly includes two square rings and two spring balancers. The two square rings are fitted onto the crossbeam at the top of the portal frame.

The cylinder mounting plate is installed at the top of the cylinder body, and the manipulator bracket is installed at the bottom of the cylinder body. The piston rod of the cylinder is connected to the top of the Y-type connector via a floating connector. The bottom of the Y-type connector is hinged to the head of the H-type connecting rod and the head of the Y-type connecting rod via a pivot. The manual directional valve is installed on the manipulator bracket via a valve seat and screws. A speed control valve is installed on each of the two ports on the side of the cylinder. The two cylinder ports of the manual directional valve are connected to the ports on the sides of the two speed control valves via air hoses. The air inlet of the manual directional valve is connected to a high-pressure air source via an air inlet pipe.

[0012] The two ends of the robotic arm support are respectively hinged to the first heads of two pressing jaws via rotating shafts, the tail of the H-shaped link is hinged to the second head of a pressing jaw via rotating shafts, and the tail of the Y-shaped link is hinged to the second head of a pressing jaw via rotating shafts.

[0013] The two ends of the robotic arm support are respectively hinged to the first heads of two disassembly grippers via rotating shafts, the tail of the H-shaped link is hinged to the second head of a disassembly gripper via a rotating shaft, and the tail of the Y-shaped link is hinged to the second head of a disassembly gripper via a rotating shaft.

[0014] The beneficial effects of this invention are: This stabilizer bar bushing vulcanizing fixture assembly and disassembly machine uses a pneumatic manipulator in conjunction with pressing jaws and disassembly jaws to press and disassemble the stabilizer bar bushing vulcanizing fixture, which has a simple structure, low cost, simple maintenance, fast pneumatic drive, and high working efficiency.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 9As shown, a stabilizer bar clamp operating device includes two rectangular worktables 1, with a rectangular plate 2 and a gantry frame 3 mounted on the top of each worktable 1.

[0028] Two symmetrical vulcanizing fixture positioning supports 4 are installed on each platform 2. The top of the vulcanizing fixture positioning support 4 is provided with a recessed vulcanizing fixture slot 39 for mounting the stabilizing rod bushing vulcanizing fixture 100. The middle of the vulcanizing fixture positioning support 4 is provided with a rectangular hollow hole 40. The bottom of the vulcanizing fixture positioning support 4 is connected to the platform 2 with screws.

[0029] Each portal frame 3 is suspended by a balancer assembly. The balancer assembly includes two square rings 11 and two spring balancers 12. The two square rings 11 are fitted onto the crossbeam at the top of the portal frame 3. A circular ring 13 is welded to the bottom end of each square ring 11. The upper hook of the spring balancer 12 is hooked onto the circular ring 13. A ring bolt 14 is screwed to the top of each end of the support rod 5. The lower hook of the spring balancer 12 is hooked into the ring bolt 14.

[0030] A set of linear guide rails 15 are installed on the inner side of the columns on both sides of the portal frame 3. A right-angle connecting block 16 is installed at the bottom of both ends of the support rod 5. The right-angle connecting block 16 is connected to the slider of the linear guide rail 15 with screws to improve the stability of the support rod 5 when it moves up and down and prevent the support rod 5 from swinging back and forth and left and right when it moves up and down.

[0031] Two pneumatic manipulators 6, capable of moving along the long axis of each support rod 5, are installed at the bottom of each support rod 5, and one pneumatic manipulator 6 is positioned directly above each vulcanizing fixture positioning support 4. Two strip-shaped holes 30 are provided on the support rod 5, arranged along its long axis, and are symmetrical about the center of the support rod 5. At least two semi-threaded bolts 31 are screwed onto the cylinder mounting plate 17, with the smooth section of each bolt fitting into the strip-shaped hole 30. Loosening the semi-threaded bolts 31 allows the pneumatic manipulators 6 to be moved, adjusting their position at the bottom of the support rod 5. Tightening the semi-threaded bolts 31 fixes the pneumatic manipulators 6 relative to the support rod.

[0032] The pneumatic manipulator 6 includes a rectangular cylinder mounting plate 17, a cylinder 18, a V-shaped manipulator bracket 19, a Y-type connector 20, a Y-type connecting rod 21, an H-type connecting rod 22, and a manual directional valve 23. The cylinder mounting plate 17 is mounted on the top of the cylinder body of the cylinder 18, and the manipulator bracket 19 is mounted on the bottom of the cylinder body of the cylinder 18. The piston rod of the cylinder 18 is connected to the top of the Y-type connector 20 via a floating connector 24. The bottom of the Y-type connector 20 is hinged to the head of the H-type connecting rod 22 and the head of the Y-type connecting rod 21 via a pivot 25. The manual directional valve 23 is mounted on the manipulator bracket 19 via a valve seat 26 and screws. A speed control valve 27 is installed on each of the two ports on the side of the cylinder 18. The two cylinder ports of the manual directional valve 23 are connected to the ports on the sides of the two speed control valves 27 via air hoses 28. The air inlet is connected to the high-pressure air source through the air inlet pipe 29; a first handle 32 is screwed to the top of one side of the robot arm bracket 19, and a V-shaped handle seat 33 is installed in the middle of the other side of the robot arm bracket 19. A second handle 34 is screwed to one end of the handle seat 33. An air inlet pipe protective plate 35 is installed on the side of the handle seat 33 away from the robot arm bracket 19. The air inlet pipe 29 is fitted into the air inlet pipe mounting hole of the air inlet pipe protective plate 35 to ensure that the air inlet pipe 29 will not be squeezed during the up and down movement of the pneumatic robot arm; a U-shaped clamping block 36 is installed at the top of the handle seat 33. An installation round rod 37 is clamped in the clamping groove of the clamping block 36. An air pipe protective rod 38 perpendicular to the installation round rod 37 is fixed to the end of the installation round rod 37 away from the clamping block 36. The air pipe protective rod 38 hooks the middle of the air delivery hose 28 to prevent the air delivery hose 28 from being squeezed.

[0033] Two pneumatic manipulators 6, mounted at the bottom of one of the support rods 5, are hinged to the bottom of two symmetrical pressing jaws 7. The first head of the pressing jaw 7 has an arc-shaped inner groove 8. The two ends of the manipulator bracket 19 are respectively hinged to the first head of the two pressing jaws 7 via a rotating shaft 25. The tail of the H-shaped link 22 is hinged to the second head of one pressing jaw 7 via a rotating shaft 25. The tail of the Y-shaped link 21 is hinged to the second head of one pressing jaw 7 via a rotating shaft 25.

[0034] Two pneumatic manipulators 6, mounted at the bottom of another support rod 5, are hinged to the bottom of two symmetrical disassembly grippers 9. The outer side of the first head of the disassembly gripper 9 is provided with an arc-shaped outer groove 10. The two ends of the manipulator bracket 19 are respectively hinged to the first heads of the two disassembly grippers 9 via a pivot 25. The tail of the H-shaped link 22 is hinged to the second head of one of the disassembly grippers 9 via a pivot 25. The tail of the Y-shaped link 21 is hinged to the second head of one of the disassembly grippers 9 via a pivot 25.

[0035] The stabilizer bar bushing vulcanizing fixture 100 includes an upper mold 101, a lower mold 102, and a connecting arm 103. The upper mold 101 and the lower mold 102 are adapted to the bushing. The upper mold 101 and the lower mold 102 are respectively inserted into half of the bushing for mating. The upper mold 101 has overlapping side ears 104 machined on both sides, and the overlapping side ears 104 have anti-detachment grooves 105. The lower mold 102 has protruding steps 106 machined on both sides. The protruding steps 106 are rotatably engaged with one end of the connecting arm 103. Specifically, the protruding steps 106 have mounting holes. The connecting arm is rotatably engaged with the protruding steps 106 through a connecting pin 107, a pin sleeve, and a washer. The mounting holes are adapted to the pin sleeve. The other end of the connecting arm 103 is rotatably engaged with a locking roller 108 through a connecting pin 103 and a washer. The locking roller 108 is adapted to the anti-detachment groove 105.

[0036] The press-fitting procedure for stabilizer bar bushing vulcanizing fixture 100 is as follows:

[0037] ① Loading: First, place the lower bushing in the lower mold 102, then clamp the lower mold 102 in the vulcanizing fixture slot 39 of the vulcanizing fixture positioning support 4, then place the stabilizing rod 200 in the lower bushing, place the upper bushing in the upper mold 101, and place the upper mold 101 on the lower mold 102, ensuring that the stabilizing rod and the upper and lower bushings are properly fitted.

[0038] ② Locking: Hold the second handle 34 on the two pneumatic manipulators 6 equipped with pressure clamping claws 7 with both hands, and move the pneumatic manipulators 6 vertically downward until the inner groove of the pressure clamping claws 7 hooks onto the locking roller 108 on the stabilizer bushing vulcanizing fixture 100.

[0039] ③ Press fitting: With both hands, manually operate the reversing valve 23 on the two pneumatic manipulators 6 equipped with press fitting claws 7. The cylinder 18 retracts, driving the pneumatic manipulator 6 to retract, thereby causing the two press fitting claws on the same pneumatic manipulator to press the two locking rollers 108 on the stabilizer bar bushing vulcanizing fixture 100 towards the middle until the locking rollers 108 are stuck in the anti-disengagement groove 105, thus fastening the upper mold 101 and the lower mold 102. Under the action of external force, the interior of the upper and lower bushings are tightly fitted with the stabilizer bar 200, and the exterior is tightly fitted with the stabilizer bar bushing vulcanizing fixture 100.

[0040] ④ Release: Release the manual reversing valve 23 on the two pneumatic manipulators 6 equipped with pressing grippers 7 with both hands. The cylinder 18 extends to drive the pneumatic manipulator 6 to open, so that the pressing grippers 7 release the locking roller 108.

[0041] ⑤ Return to the initial state: Hold the second handle 34 on the two pneumatic manipulators 6 equipped with pressing jaws 7 with both hands, and move the pneumatic manipulators vertically upward until the pressing jaws 7 are away from the vulcanizing fixture 100 of the stabilizing rod bushing.

[0042] The disassembly procedure for stabilizer bar bushing vulcanizing fixture 100 is as follows:

[0043] ⑥ Loading: Place the stabilizer bar, stabilizer bar bushing and stabilizer bar bushing vulcanization fixture that have undergone vulcanization process onto the vulcanization fixture positioning support, so that the bottom of the stabilizer bar bushing vulcanization fixture is locked in the vulcanization fixture slot 39.

[0044] ⑦ Descent of the robotic arm: Hold the second handle 34 on the two pneumatic robotic arms 6 equipped with disassembly grippers 9 with both hands, so that the pneumatic robotic arms move vertically downward until the outer groove of the disassembly grippers 9 contacts the locking roller 108.

[0045] ⑧ Fixture disassembly and assembly: Press the manual reversing valve 23 on the two pneumatic manipulators 6 equipped with disassembly grippers 9 with both hands respectively. The cylinder 18 extends and drives the pneumatic manipulator 6 to open. The disassembly grippers 9 quickly push the locking roller 108 outward, so that the locking roller 108 disengages from the anti-disengagement groove 105, allowing the upper mold and the lower mold to separate from each other.

[0046] ⑨ Release the robotic arm: Release the manual reversing valve 23 on the two pneumatic robotic arms 6 equipped with disassembly grippers 9 with both hands. The cylinder 18 retracts to drive the pneumatic robotic arm 6 to retract, so that the disassembly grippers 9 are separated from the locking roller 108.

[0047] ⑩ Return the robotic arm to its original position: Hold the second handle 34 on the two pneumatic robotic arms 6 equipped with disassembly grippers 9 with both hands, and move the pneumatic robotic arms vertically upward until the disassembly grippers 9 are away from the vulcanizing fixture 100 of the stabilizer bushing.

[0048] Replacing the original hydraulic transmission with pneumatic transmission has the following advantages: 1. The air pressure entering the cylinder can be adjusted using the speed control valve 27 to regulate the cylinder's output force, making it easy to adjust the output force; 2. Due to the low viscosity of air, the pressure drop in the pipeline is small and the flow rate is fast, enabling high-speed operation and accelerating the cycle of pressing and disassembly; 3. Not only can an air compressor be used as a high-pressure air source, but a high-pressure gas can also be stored in an air tank; 4. No highly specialized knowledge or technology is required, and maintenance is simple; 5. Compared to hydraulic manipulators, pneumatic manipulators are one-tenth the price of hydraulic assembly machines, and have a simpler structure and lower cost.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
