Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical clamping jaws, in particular to a shock absorber piston clamping jaw with intelligent detection function for assembly and an assembly equipment. BACKGROUND

[0002] The assembly of a shock absorber needs to be meticulous. First, prepare the required piston, cylinder barrel, sealing element and other parts, carefully check their quality, and eliminate defective parts. Then, accurately install the sealing element to the specified position of the cylinder barrel to ensure good sealing. Then carefully assemble the piston into the cylinder barrel, paying attention to the fit clearance between the piston and the cylinder barrel. Then install the guide seat and other parts, and tighten the connecting bolts according to the standard torque. After assembly, preliminary function test is required to check whether the piston moves flexibly and whether there is oil leakage, etc., to ensure the assembly quality.

[0003] For the installation of the piston and the piston rod, an installation device is needed, such as the patent CN115139085A, an automobile shock absorber piston rod assembly device and production process, which comprises: a rack; a clamping seat provided on the rack, the side of the clamping seat away from the rack is provided with a plug-in groove for the non-threaded end of the shock absorber piston rod; a clamping mechanism provided on the rack to clamp the shock absorber piston rod inserted into the plug-in groove; a tightening drive source provided on the rack, the tightening drive source is connected with the rack in the vertical direction; an internal hex sleeve detachably connected to the output shaft of the tightening drive source, the internal hex sleeve is provided towards the rack and concentrically with the plug-in groove; and a lifting mechanism provided on the rack and transmission connected with the tightening drive source to drive the tightening drive source to approach or move away from the shock absorber piston rod. It has the effect of tightening the nut on the threaded end of the shock absorber piston rod to fix the piston.

[0004] When installing the piston and the piston rod, the piston is clamped and moved to the upper end of the piston rod by the clamping jaw, and then the piston is sleeved on the piston rod by hydraulic means, and is limited by a circlip or a bolt. The above device and the existing piston clamping jaw only have the effect of clamping and pushing, and cannot automatically detect and correct problems that occur during assembly, making it difficult to ensure the reliability and efficiency of automated production. SUMMARY

[0005] The present application aims to provide a shock absorber piston clamping jaw with intelligent detection function for assembly and an assembly equipment to solve the problems raised in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shock absorber piston clamping claw with intelligent detection function for assembly, comprising a connecting plate, a vertically distributed pressure rod slidably disposed at the front end of the connecting plate, and a first cylinder for controlling the lifting and lowering of the pressure rod installed above the connecting plate, a plurality of infrared sensors for positioning fixed at the front end of the connecting plate, a push plate slidably sleeved on the pressure rod, the push plate being located below the connecting plate, and a lifting rod fixed at the upper end of the push plate, the lifting rod slidingly penetrating through the connecting plate, a second cylinder for controlling the up and down movement of the lifting rod installed on the upper surface of the connecting plate, an adjustment mechanism disposed at the lower end of the connecting plate, and a pneumatic clamping claw connected below the adjustment mechanism, two moving claws disposed at the front end of the pneumatic clamping claw, a clamping claw disposed on the outer side of the moving claw, and a lifting mechanism disposed between the moving claw and the clamping claw, a correction plate disposed below the pneumatic clamping claw, and a telescopic mechanism for controlling the movement of the correction plate disposed below the pneumatic clamping claw.

[0007] Preferably, the lifting mechanism includes a vertical slide rail fixed to the inner side of the gripping claw and a slider fixed to the outer side of the moving claw. The slider is slidably mounted on the vertical slide rail. A fixing plate is fixed to the upper end of the vertical slide rail by bolts. Compression springs are provided between the moving claw and the fixing plate, and between the moving claw and the bottom of the gripping claw.

[0008] Preferably, the moving claw and the slider are provided with through holes, and the vertical slide rail and the clamping claw are provided with long slots, the width of which is smaller than the diameter of the through holes. A double-headed motor is fixed at the middle of the front end of the pneumatic gripper, and flat rods are fixed at both ends of the double-headed motors. The flat rods pass through the through holes and the long slots, and the minimum radial width of the flat rods is smaller than the width of the long slots, while the maximum radial width of the flat rods is greater than the width of the long slots.

[0009] Preferably, the adjustment mechanism includes a first mounting plate disposed between the pneumatic gripper and the connecting plate. Two horizontal slide rails are fixed below the connecting plate, and two horizontal slide blocks are fixed on the first mounting plate, with the horizontal slide blocks slidably connected to the horizontal slide rails. A third cylinder is fixed below the connecting plate, located between the two horizontal slide rails, and a connecting seat is fixed at the upper end of the first mounting plate. The output shaft of the third cylinder is fixed to the connecting seat. Two side plates are fixed at the lower end of the first mounting plate, and a threaded rod and a first guide rod are fixed between the two side plates, with the first guide rod being perpendicular to the horizontal slide rails. A screw motor connected to the threaded rod and a first fixing sleeve slidably sleeved on the first guide rod are fixed above the pneumatic gripper.

[0010] Preferably, the telescopic mechanism includes a second mounting plate fixed below the pneumatic gripper, a fourth cylinder fixed below the second mounting plate, a correction plate fixed on the output shaft of the fourth cylinder, and two symmetrically distributed second fixing sleeves fixed on both sides of the fourth cylinder. A second guide rod is slidably disposed in the second fixing sleeve, and the end of the second guide rod is fixed to the correction plate.

[0011] Preferably, a rear detection mechanism is provided below the pneumatic gripper for detecting the assembly effect of the piston rod and the piston. The rear detection mechanism includes two symmetrically distributed brackets fixed below the second mounting plate. Two swing arms are rotatably mounted on the brackets, and a drive motor for driving the swing arms to rotate is mounted on the brackets. The other end of the swing arms is connected to a mounting frame. A first curved plate is fixed on one mounting frame, and two second curved plates are fixed on the other mounting frame. The second curved plates are located on the upper and lower sides of the first curved plate, respectively. A lifting cylinder is mounted on both mounting frames, and a pressure sensor is fixed to the upper end of the lifting cylinder.

[0012] Preferably, the mounting frame is rotatably provided with connecting channel steel, one of the connecting channel steels is fixedly connected to the swing arm at the corresponding position, the other connecting channel steel is provided with a lifting slot, and the end of the other swing arm is provided with a sliding member, which is slidably disposed in the lifting slot. The upper and lower ends of the connecting channel steel with the lifting slot are fixed with connecting plates, and elastic ropes are connected between the two connecting plates and the lifting slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The piston is clamped by a calibration plate and a pressure rod to ensure that the piston is level, and the piston tilt can be detected and corrected. Multiple infrared sensors detect the piston edge, and the piston position is adjusted by an adjustment mechanism to detect and correct the center position of the piston, which can improve the reliability and efficiency of automated production.

[0015] Meanwhile, once the piston is leveled, the dual-head motor drives the flat rod to rotate. By changing the width of the flat rod, the two sides of the flat rod abut against the two sides of the long slot. The friction force limits the gripping claw, preventing it from moving under the action of the compression spring. This allows it to be fixed in any position, reducing stroke error.

[0016] Furthermore, through the post-inspection mechanism, after the piston rod is clamped in the middle by the first and second bending plates, the two pressure sensors move upward synchronously. When the pressure on the two pressure sensors remains consistent, it indicates that the piston rod and piston are installed normally; otherwise, it indicates that the piston is installed at an angle. This enables post-installation inspection, timely rejection of unqualified products, and improvement of product quality.

[0017] In addition, the mounting bracket and the connecting channel steel are rotatably connected. The mounting bracket, the first bending plate, and the second bending plate can tilt. Even when the piston rod is tilted, they can still fit against the piston rod surface. Furthermore, one of the connecting channel steels can slide up and down with the swing arm. Even when the piston rod is tilted, the first bending plate and the second bending plate can still be interlaced to prevent the device from jamming and ensure the accuracy of the test.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] During piston installation, the clamping position and angle of the piston are detected by the clamping claws, which can further improve the assembly accuracy, reduce the failure rate and downtime rate, and thus ensure the reliability and efficiency of automated production.

[0029] like Figures 1-7 As shown, the present invention provides a technical solution: a shock absorber piston clamping claw with intelligent detection function for assembly, including a connecting plate 1, a vertically distributed pressure rod 2 slidably disposed at the front end of the connecting plate 1, and a first cylinder 3 for controlling the lifting and lowering of the pressure rod 2 installed above the connecting plate 1, a plurality of infrared sensors 4 for positioning fixed at the front end of the connecting plate 1, a push plate 5 slidably sleeved on the pressure rod 2, the push plate 5 being located below the connecting plate 1, and a lifting rod 6 fixed at the upper end of the push plate 5, the lifting rod 6 slidingly penetrating the connecting plate 1, a second cylinder 7 for controlling the up and down movement of the lifting rod 6 installed on the upper surface of the connecting plate 1, an adjustment mechanism disposed at the lower end of the connecting plate 1, and a pneumatic clamping claw 8 connected below the adjustment mechanism, two moving claws 9 disposed at the front end of the pneumatic clamping claw 8, a clamping claw 10 disposed on the outer side of the moving claws 9, and a lifting mechanism disposed between the moving claws 9 and the clamping claws 10, a correction plate 11 disposed below the pneumatic clamping claw 8, and a telescopic mechanism for controlling the movement of the correction plate 11 disposed below the pneumatic clamping claw 8.

[0030] It is important to note that the two moving claws 9 on the pneumatic gripper 8 drive the two clamping claws 10 to move, thus clamping the piston. The alignment plate 11 can extend below the piston, and then the pressure rod 2 descends, causing the piston to move downward (although the piston is clamped by the clamping claws 10, the clamping claws 10 can move up and down under the action of the lifting mechanism), so that the bottom of the piston fits against the alignment plate 11. Moreover, the two clamping claws 10 can move independently, which can prevent the piston from tilting. Then, multiple infrared sensors 4 detect the edge of the piston, and the adjustment mechanism drives the pneumatic gripper 8 to move, so that each infrared sensor 4 can detect the edge of the piston. After alignment, the lifting mechanism locks the clamping claws 10, and installation can be carried out. First, the piston is clamped above the piston rod, the clamping claws 10 are released, the pressure rod 2 pushes the piston against the upper end of the piston rod, and then the push plate 5 presses downward to install the piston onto the piston rod. During the installation process, the tilting of the piston and the center position of the piston can be detected and corrected, which can improve the reliability and efficiency of automated production.

[0031] like Figure 4As shown, the lifting mechanism includes a vertical slide rail 12 fixed inside the gripper 10 and a slider 13 fixed outside the moving gripper 9. The slider 13 is slidably mounted on the vertical slide rail 12. A fixing plate 14 is fixed to the upper end of the vertical slide rail 12 by bolts. Compression springs 15 are provided between the moving gripper 9 and the fixing plate 14, and between the moving gripper 9 and the bottom of the gripper 10.

[0032] It should be noted that the position of the clamping claw 10 is stabilized by two compression springs 15, and the clamping claw 10 can move in both the up and down directions to ensure the adjustment range of the clamping claw 10. Moreover, the fixing plate 14 is detachable. After removing the fixing plate 14, the slider 13 can be slid out and the compression springs 15 on both sides can be replaced. The operation is simple during maintenance and assembly.

[0033] like Figure 2 and Figure 4 As shown, the moving claw 9 and the slider 13 are provided with through holes 16, and the vertical slide rail 12 and the clamping claw 10 are provided with long slots 17. The width of the long slots 17 is smaller than the diameter of the through holes 16. A double-headed motor 18 is fixed at the middle of the front end of the pneumatic gripper 8, and flat rods 19 are fixed at both ends of the double-headed motor 18. The flat rods 19 pass through the through holes 16 and the long slots 17. The minimum radial width of the flat rods 19 is smaller than the width of the long slots 17, and the maximum radial width of the flat rods 19 is greater than the width of the long slots 17.

[0034] It should be noted that when the gripper 10 moves up and down, the flat rod 19 moves up and down inside the long slot 17 without obstructing the lifting and lowering of the gripper 10. However, after the piston is corrected to a horizontal state, the dual-head motor 18 can drive the flat rod 19 to rotate. By changing the width of the flat rod 19, the two sides of the flat rod 19 are brought into contact with the two sides of the long slot 17. The friction force limits the gripper 10 and prevents it from moving under the action of the compression spring 15.

[0035] like Figure 2 and Figure 3As shown, the adjustment mechanism includes a first mounting plate 21 disposed between the pneumatic gripper 8 and the connecting plate 1. Two horizontal slide rails 20 are fixed below the connecting plate 1. Two horizontal slide blocks 22 are fixed on the first mounting plate 21, and the horizontal slide blocks 22 are slidably connected to the horizontal slide rails 20. A third cylinder 23 is fixed below the connecting plate 1. The third cylinder 23 is located between the two horizontal slide rails 20, and a connecting seat is fixed at the upper end of the first mounting plate 21. The output shaft of the third cylinder 23 is fixed to the connecting seat. Two side plates 24 are fixed at the lower end of the first mounting plate 21. A threaded rod 25 and a first guide rod 26 that are parallel to each other are fixed between the two side plates 24. The first guide rod 26 is perpendicular to the horizontal slide rails 20. A screw motor 27 connected to the threaded rod 25 and a first fixed sleeve 28 that is slidably sleeved on the first guide rod 26 are fixed above the pneumatic gripper 8.

[0036] It should be noted that the third cylinder 23 can drive the first mounting plate 21 to move along the horizontal slide rail 20, and the lead screw motor 27 can drive the pneumatic gripper 8 to move along the first guide rod 26. At the same time, when the first mounting plate 21 moves, the pneumatic gripper 8 will also move synchronously along the horizontal slide rail 20, thereby realizing the adjustment of the pneumatic gripper 8 on the two-dimensional plane, and thus realizing the adjustment of the piston position. The position of the piston can be determined by working with the infrared sensor 4.

[0037] like Figure 2 and Figure 3 As shown, the telescopic mechanism includes a second mounting plate 29 fixed below the pneumatic gripper 8, a fourth cylinder 30 fixed below the second mounting plate 29, a correction plate 11 fixed on the output shaft of the fourth cylinder 30, and two symmetrically distributed second fixing sleeves 31 fixed on both sides of the fourth cylinder 30. A second guide rod 32 is slidably disposed in the second fixing sleeve 31, and the end of the second guide rod 32 is fixed to the correction plate 11.

[0038] It should be noted that the position of the calibration plate 11 is adjusted by the extension and retraction of the fourth cylinder 30. It extends during calibration and retracts during assembly. The two second guide rods 32 provide further stabilization for the movement of the calibration plate 11, preventing it from shaking and also preventing the calibration plate 11 from tilting, thus improving structural stability.

[0039] like Figure 5 , Figure 6 and Figure 7As shown, a rear detection mechanism is provided below the pneumatic gripper 8 for detecting the assembly effect of the piston rod and the piston. The rear detection mechanism includes two symmetrically distributed brackets 33 fixed below the second mounting plate 29. Two swing arms 34 are rotatably mounted on the brackets 33, and a drive motor 35 for driving the swing arms 34 to rotate is mounted on the brackets 33. The other end of the swing arms 34 is connected to a mounting bracket 36. A first curved plate 37 is fixed on one mounting bracket 36, and two second curved plates 38 are fixed on the other mounting bracket 36. The second curved plates 38 are located on the upper and lower sides of the first curved plate 37, respectively. A lifting cylinder 39 is mounted on both mounting brackets 36, and a pressure sensor 40 is fixed to the upper end of the lifting cylinder 39.

[0040] It is important to note that after the piston is installed, the drive motor 35 drives the swing arm 34 to rotate, causing the first bending plate 37 and the second bending plate 38 to clamp the piston rod in the middle. Moreover, the first bending plate 37 and the second bending plate 38 are detached from each other and will not abut against each other. After clamping the piston rod, the lifting cylinder 39 extends, causing the two pressure sensors 40 to move upward synchronously. When the pressure on the two pressure sensors 40 remains consistent, it indicates that the piston rod and piston are installed normally. Otherwise, it indicates that the piston is installed at an angle. This allows for post-installation inspection, timely rejection of unqualified products, and improvement of product quality.

[0041] like Figure 7 As shown, a connecting channel steel 41 is rotatably mounted on the mounting frame 36. One of the connecting channel steel 41 is fixedly connected to the corresponding swing arm 34. The other connecting channel steel 41 has a lifting slot 42, and the end of the other swing arm 34 is provided with a sliding member 43. The sliding member 43 is slidably disposed in the lifting slot 42. Both the upper and lower ends of the connecting channel steel 41 with the lifting slot 42 are fixed with connecting pieces 44, and elastic ropes 45 are connected between the two connecting pieces 44 and the lifting slot 42.

[0042] It should be noted that the mounting bracket 36 and the connecting channel steel 41 are rotatably connected, allowing the mounting bracket 36, the first bent plate 37, and the second bent plate 38 to tilt. When the piston rod is tilted, they can still fit against the piston rod surface. Moreover, as the piston rod tilts, the first bent plate 37 and the second bent plate 38 still intersect each other. At this time, one of the mounting brackets 36 can move up and down along the sliding member 43 to ensure that the first bent plate 37 and the second bent plate 38 do not jam against each other, thereby ensuring the accuracy of the detection.

[0043] like Figure 8 As shown, an assembly equipment for shock absorbers with intelligent detection function is provided, which uses the aforementioned shock absorber piston clamping claw with intelligent detection function.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
