Description

Technical Field

[0001] The present application relates to the technical field of hydraulic shock absorbers, and in particular to an installation structure for facilitating replacement of hydraulic shock absorber clamps. Background Art

[0002] In the machinery manufacturing industry, hydraulic shock absorbers are important vibration-damping components on the primary and secondary suspension devices of bogies (axles) of locomotives (diesel locomotives, electric locomotives), subway vehicles, urban light rail vehicles and large passenger vehicles on highways. They achieve the purpose of vibration reduction by forming hydraulic damping force through the reciprocating motion of the stretching and compressing piston rods. They have good vibration damping effect and flexible vibration reduction effect. They are key components for improving the stability, comfort and safety of high-speed operation of locomotives and vehicles. In the process of producing and repairing hydraulic vibration reduction equipment, it is generally necessary to disassemble the hydraulic shock absorbers. The disassembly method needs to take different disassembly measures according to different types of hydraulic shock absorbers.

[0003] After checking the announcement number: CN 213054630 U, a hydraulic shock absorber disassembly device for locomotives is disclosed. This technology discloses "an operating table, a clamping mechanism and a disassembly mechanism; the operating table surface is provided with a through hole for facilitating the up and down movement of the hydraulic shock absorber, the hydraulic shock absorber is vertically arranged in the through hole, the clamping mechanism is arranged below the through hole, and is used to clamp the protective cover shell of the hydraulic shock absorber; the disassembly mechanism is arranged above the through hole, and the disassembly mechanism includes a wrench for disassembling the hydraulic shock absorber protective cover, and the wrench is arranged vertically downward, etc., which can replace the existing disassembly method using a wrench, reduce the manual disassembly labor of workers, save time and effort; the use of hydraulic and pneumatic systems can provide stable output force and torque, and improve work efficiency; the utility model can save the heating shock absorber link in the disassembly process, has the technical effects of reducing damage to the shock absorber and simplifying the disassembly steps, etc.";

[0004] With respect to the above-mentioned related technologies, the inventors believe that different hydraulic shock absorbers have different outer shell diameters. When faced with different hydraulic shock absorbers, the inner diameter of the clamping claws of the clamping mechanism of the same disassembly device is fixed, which makes the disassembly device unable to be applied to the disassembly of hydraulic shock absorbers of different sizes and types. In addition, the disassembly and replacement of the clamping mechanism is complicated, and often requires multiple workpieces to assist in disassembly, which takes a long time and affects work efficiency. Utility Model Content

[0005] The purpose of the present application is to provide a mounting structure that is convenient for replacing a hydraulic shock absorber clamp, so as to improve the problem of inconvenience in disassembling hydraulic shock absorbers of different sizes and inconvenience in replacing the clamping mechanism.

[0006] The present application provides an installation structure for replacing a fixture, which adopts the following technical solution:

[0007] The top end of the support plate is fixedly provided with a cylinder, and the output end of the cylinder passes through the connecting plate and is fixedly connected to the connecting plate. The outer surface of the support plate is fixedly provided with four quick connectors, one end of the back plate is fixedly connected to an electric slide rail, the outer surface of the electric slide rail is slidably sleeved with an electric slider, one end of the electric slider is fixedly connected to a connecting plate, the bottom end of the connecting plate is provided with an internal support device, the top end of the bottom plate is fixedly sleeved with a plurality of locking rings, the internal support device comprises a support kit, a telescopic rod is inserted and connected to the outer surface of the middle portion of the support kit, a cylinder is fixedly provided on the top of the connecting plate, the output end of the cylinder passes through the connecting plate and is fixedly connected to the telescopic rod, the outer surface of the support kit is rotatably connected to three first connecting plates, one end of the three first connecting plates are rotatably connected to the support plate, one end of the three support plates are rotatably connected to the second connecting plate, and one end of the three second connecting plates are rotatably connected to the telescopic rod.

[0008] By adopting the above technical solution, after the hydraulic shock absorber is fixed, the inner support device is placed in the inner diameter of the hydraulic shock absorber, and the cylinder is started, and the output end of the cylinder pushes the telescopic rod vertically inside the support kit. During the pushing process, the telescopic rod drives the second connecting plate rotatably connected to it to rotate upward, and the three rotating second connecting plates thereby drive the three support plates connected to the second connecting plates to expand. The three expanded support plates are kept balanced by the three first connecting plates, and the hydraulic shock absorber is internally supported and fixed, and then the connecting plate is driven to move upward by the electric slider on the electric slide rail, thereby driving the inner support device to move upward, and the outer shell and inner shell of the hydraulic shock absorber are separated.

[0009] Optionally, the locking ring includes a locking sleeve, a connecting groove is provided on a middle outer surface of the locking sleeve, and a clamping groove is provided on an outer surface of the connecting groove.

[0010] By adopting the above technical solution, a quick replacement operation is performed through the cooperation of the locking sleeve and the quick connector. The knob is pressed down and rotated to drive the main shaft fixedly connected to the knob to rotate. The force of the spring of the main shaft sleeve drives the locking pin to contract, thereby causing the locking pin to disengage from the connecting groove, thereby achieving the purpose of quick disengagement.

[0011] Optionally, the fixing device includes a fixing plate, the top of the fixing plate is fixedly connected to four quick connectors, the top of the fixing plate is fixedly connected to a support plate, both ends of the support plate are jointly interspersed and rotatably connected with a bidirectional threaded rod, the different thread directions engraved on the outer surface of the bidirectional threaded rod are all sleeved with clamping plates, and one end of the bidirectional threaded rod is fixedly connected to a rotating handle.

[0012] By adopting the above technical solution, when the hydraulic shock absorber housing needs to be disassembled, the clamping plate in the fixing device is first used to drive the bidirectional threaded rod to rotate by rotating the handle, and the rotating bidirectional threaded rod drives the two clamping plates to move horizontally in opposite directions, thereby achieving the purpose of fixing the hydraulic shock absorber housing.

[0013] Optionally, the quick connector includes a fixing ring, the inner surface of the fixing ring is interspersed with a sleeve, the inner surface of the sleeve is interspersed with a main shaft, the outer surface of the main shaft is fixedly sleeved with a spring, the top end of the main shaft is fixedly connected with a knob, the bottom end of the main shaft is fixedly connected with a locking pin, the outer surfaces of both sides of the locking pin are fixedly connected with a bayonet pin, and the locking ring is used in conjunction with the quick connector.

[0014] By adopting the above scheme, the locking pin in the quick connector is aligned with the connecting groove in the quick bolt. The operator first presses the knob downward and rotates it. The pressed knob pushes the locking pin downward through the sleeve spring of the main shaft. After rotation, the two locking pins are stuck on the inner wall of the slot, thereby achieving the purpose of quick locking.

[0015] Optionally, the three support plates are distributed in a ring array, and the outer surfaces of the three support plates are each provided with a plurality of strip grooves.

[0016] By adopting the above technical solution, the three support plates distributed in a circular array are pushed by the cylinder to move outward synchronously with the telescopic rod as the axis point, so that the three supported plates can clamp and tighten the inner wall of the hydraulic shock absorber, and the strip grooves on the surface of the support plates play a role in increasing friction.

[0017] Optionally, the clamping plate is K-shaped, and an outer surface of the clamping plate is slidably fitted with an outer surface of the support plate.

[0018] The purpose of adopting the above-mentioned technical solution is to facilitate the rotation of the two clamping plates through the bidirectional threaded rod, so that the two clamping plates can slide horizontally toward each other on the outer surface and upper outer surface of the groove at the support plate, thereby facilitating the V-shaped groove at one end of the clamping plate to clamp and position the hydraulic shock absorber at two points.

[0019] Optionally, the center point of the inner support device and the center point of the fixed plate are on the same vertical horizontal line.

[0020] The above technical solution is adopted to facilitate the center point of the oil pressure shock absorber and the center point of the inner support device to be on the same horizontal line after the oil pressure shock absorber is clamped and positioned by the inner support device.

[0021] Optionally, the diameter of the locking pin is the same as the diameter of the connecting groove, and the outer surface of the locking pin is slidably fitted with the inner surface of the connecting groove.

[0022] The above technical solution is adopted to facilitate operators to insert the locking pin into the connection groove and implement the connection locking operation more quickly and effectively.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

The utility model provides an inner support device and a fixing device so that when an operator faces a hydraulic shock absorber housing of different sizes, the fixing device can be used to clamp and position it. The outer support characteristics of the inner support mechanism are suitable for hydraulic shock absorbers of different inner diameters, thereby increasing the applicability of disassembly work.

[0025] 2. The utility model uses the cooperation of the quick connector and the locking ring to enable the fixing device and the base plate to be quickly separated and installed through the quick connectors around when the hydraulic shock absorbers of different sizes are used, so that the operator can replace the corresponding fixtures conveniently, reduce the time used for replacing the fixtures, and improve work efficiency.

Example

[0039] The difference between this embodiment and embodiment 1 is that:

[0040] Reference Figure 4 The locking ring 5 includes a locking sleeve 51 , a connecting groove 52 is formed on the outer surface of the middle portion of the locking sleeve 51 , and a clamping groove 53 is formed on the outer surface of the connecting groove 52 .

[0041] Reference Figure 4The quick connector 6 includes a fixing ring 61, the inner surface of which is interlaced with a shaft sleeve 62, the inner surface of which is interlaced with a main shaft 64, the outer surface of which is fixedly sleeved with a spring 65, the top of which is fixedly connected with a knob 63, the bottom end of which is fixedly connected with a locking pin 66, and the outer surfaces of both sides of the locking pin 66 are fixedly connected with bayonet pins 67. The locking ring 5 is used in conjunction with the quick connector 6. When it is necessary to replace the fixing device 4, a quick replacement operation is performed through the cooperation of the locking ring 5 and the quick connector 6. The knob 63 is pressed down and rotated to drive the main shaft 64 fixedly connected to the knob 63 to rotate. The rotating main shaft 64 drives the locking pin 66 and the bayonet pins 67 at both ends to rotate between the inner walls of the connecting groove 52. When the two bayonet pins 67 are level with the bayonet ports at both ends of the connecting groove 52, the main shaft 64 is in a state of being locked. The force of the spring 65 sleeved on the shaft 64 drives the locking pin 66 to retract the bayonet pin 67, so that the locking pin 66 is separated from the connecting groove 52, achieving the purpose of quick separation, thereby quickly disassembling the fixing plate 41, and facilitating the operator to replace the fixture. When installation is required, the locking pin 66 in the quick connector 6 is aligned with the connecting groove 52 in the locking ring 5. The operator first applies pressure downward on the knob 63. The pressed knob 63 pushes the locking pin 66 downward on the main shaft 64 through the sleeved spring 65. The pushed-out locking pin 66 abuts against the connecting groove 52. At this time, the two bayonet pins 67 are located at the bayonet slot 53. Then the knob 63 is rotated, thereby driving the bayonet pins 67 at both ends of the locking pin 66 to rotate in the bayonet slot 53. The two bayonet pins 67 after rotation are stuck on the inner wall of the bayonet slot 53, thereby achieving the purpose of quick locking.

[0042] Reference Figure 4 The diameter of the two latches 67 is the same as the diameter of the slot 53, so that the latches 67 at both ends can be engaged with the slot 53 through the process of pressing down and rotating, thereby achieving the locking purpose.
