Description

Technical Field

[0001] The present application relates to the technical field of shock absorber maintenance auxiliary tools, and in particular to a shock absorber separation clamp. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after absorbing shock, as well as the impact from the road surface. They are used in many fields, such as automobiles and train tracks.

[0003] The most common shock absorber is the hydraulic shock absorber, which mainly includes an oil storage cylinder, a pressure cylinder fixedly connected to the inside of the oil storage cylinder, and a piston rod slidingly fitted in the pressure cylinder. When the piston rod moves relatively, the oil can flow from one cavity to another through different pores and repeatedly flow. The friction between the pores and the oil and the friction between the oil molecules form a damping force to achieve a shock absorption effect.

[0004] When shock absorbers are used on railway tracks, they usually need to be regularly maintained and inspected. During the removal of the piston rod, the oil storage cylinder needs to be fixed, and then the piston rod is pulled by equipment. Due to the resistance between the piston rod and the pressure cylinder, the pressure cylinder and the piston rod are easily pulled out, which causes certain inconveniences during the maintenance of the shock absorber. Utility Model Content

[0005] In order to facilitate the staff to disassemble the shock absorber piston rod, the present application provides a shock absorber separation clamp.

[0006] The shock absorber separation fixture provided in this application adopts the following technical solution:

[0007] A shock absorber separation clamp comprises a first clamping mechanism for clamping an oil storage cylinder of the shock absorber and a second clamping mechanism for clamping a pressure cylinder of the shock absorber, wherein the second clamping mechanism is connected to the first clamping mechanism.

[0008] By adopting the above technical solution, when disassembling the shock absorber, the first clamping mechanism is used to clamp on the oil storage cylinder, and the second clamping mechanism is used to clamp on the pressure cylinder, so as to achieve further connection between the pressure cylinder and the oil storage cylinder, thereby preventing the pressure cylinder and the oil storage cylinder from separating during the process of pulling out the piston rod.

[0009] Optionally, the first clamping mechanism includes two clamping members, one end of the two clamping members are rotatably connected, and rotating the clamping members can make the two clamping members move closer to or farther away from each other.

[0010] By adopting the above technical solution, the oil storage cylinder is arranged between the two clamping members, and the clamping members are rotated to make the two clamping members approach each other to achieve clamping of the oil storage cylinder.

[0011] Optionally, the two clamping members are provided with fitting grooves, and the side walls of the fitting grooves can fit with the side walls of the oil storage cylinder.

[0012] By adopting the above technical solution, the movement of the oil storage cylinder can be limited by the fitting groove, and at the same time the contact area between the clamping member and the oil storage cylinder is increased, thereby improving the stability of the clamping.

[0013] Optionally, the first clamping mechanism also includes a locking assembly, which includes a threaded rod and a locking rod, defining two clamping members as a first clamping member and a second clamping member, one end of the threaded rod is connected to the first clamping member, and the other end passes through the second clamping member and extends to a side away from the first clamping member, the locking rod is screwed to the threaded rod, and rotating the locking rod can make the locking rod press against the second clamping member.

[0014] By adopting the above technical solution, the locking rod is rotated to make the locking rod press against the clamping member, thereby preventing the two clamping members from rotating away from each other, thereby improving the stability of the clamping member clamping the oil storage cylinder.

[0015] Optionally, the threaded rod can rotate around an axis parallel to the rotation axis of the clamping member, and a connecting hole is opened on the second clamping member corresponding to the threaded rod. The connecting hole forms an opening on the side away from the rotation axis of the clamping member itself, and rotating the threaded rod can cause the threaded rod to disengage from the connecting hole.

[0016] By adopting the above technical solution, rotating the threaded rod can disengage the threaded rod from the connecting hole, thereby eliminating the limit on the rotation of the clamping member, making it convenient for workers to disassemble the clamping member or set the clamping member outside the oil storage cylinder.

[0017] Optionally, the locking assembly further includes a rocker arm, which is arranged on the locking rod along a direction perpendicular to the length of the threaded rod.

[0018] By adopting the above technical solution, the staff can drive the locking rod to rotate by toggling the rocker, and the rocker increases the force arm when the staff rotates the locking rod, thereby making it easier for the staff to press the locking rod against the clamping piece.

[0019] Optionally, the second clamping mechanism has the same structural principle as the first clamping mechanism, and the threaded rod of the locking assembly in the second clamping mechanism is connected to the second clamping member.

[0020] By adopting the above technical solution, the threaded rod of the second clamping mechanism is connected to the second clamping member, so that the positions of the first clamping mechanism and the second clamping mechanism are staggered, thereby reducing the interference between the two rockers during the rotation process.

[0021] Optionally, a connecting assembly is provided between the first clamping mechanism and the second clamping mechanism, and the connecting assembly includes a connecting rod, and the clamping members of the first clamping mechanism and the second clamping mechanism are rotatably sleeved on the connecting rod.

[0022] By adopting the above technical solution, the clamping member is rotatably sleeved on the connecting rod, thereby realizing the rotational connection of two clamping members in the same group and realizing the connection between the two groups of clamping mechanisms.

[0023] In summary, the present application includes the following beneficial technical effects: the positions of the oil storage cylinder and the pressure cylinder are fixed by the first clamping mechanism and the second clamping mechanism, thereby reducing the occurrence of the pressure cylinder and the oil storage cylinder being detached during the piston rod extraction process, making it easier for staff to repair the shock absorber.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] An embodiment of the present application discloses a shock absorber separation clamp.

[0029] Reference Figure 1 The shock absorber includes an oil storage cylinder 11 and a pressure cylinder 12. Both the oil storage cylinder 11 and the pressure cylinder 12 are circular barrel structures. The pressure cylinder 12 is coaxially arranged inside the oil storage cylinder 11, and one end extends to the outside of the oil storage cylinder 11. A piston rod 13 is slidably fitted inside the pressure cylinder 12. During the maintenance of the shock absorber, the piston rod 13 needs to be pulled out of the pressure cylinder 12.

[0030] Reference Figure 1 and Figure 2A shock absorber separation clamp includes a first clamping mechanism 2 and a second clamping mechanism 3. The first clamping mechanism 2 is used to clamp an oil storage cylinder 11. The second clamping mechanism 3 is arranged on one side of the first clamping mechanism 2 and is used to clamp the end of a pressure cylinder 12. The second clamping mechanism 3 is connected to the first clamping mechanism 2, so as to achieve the fixation between the pressure cylinder 12 and the oil storage cylinder 11, and prevent the pressure cylinder 12 from escaping from the oil storage cylinder 11 during the process of pulling out the piston rod 13, so as to facilitate the maintenance of the shock absorber by the staff.

[0031] Reference Figure 1 and Figure 2 The first clamping mechanism 2 includes two clamping members 21, and the clamping members 21 are long strip structures. The two clamping members 21 are arranged in a direction perpendicular to their own length. One end of the two clamping members 21 is rotatably connected to each other. Rotating the clamping members 21 can make the two clamping members 21 approach or move away from each other, thereby clamping the oil storage cylinder 11. A fitting groove 22 is provided on the side where the two clamping members 21 are close to each other, which passes through in a direction parallel to their own rotation axis. The fitting groove 22 matches the shape of the oil storage cylinder 11. In this embodiment, the fitting groove 22 is an arc groove. After the two clamping members 21 clamp the oil storage cylinder 11, the side of the fitting groove 22 fits with the outer wall of the oil storage cylinder 11, thereby improving the stability of clamping the oil storage cylinder 11. In this embodiment, the fitting groove 22 is formed by stamping and bending the long strip clamping member 21.

[0032] Reference Figure 1 and Figure 2 The first clamping mechanism 2 further includes a locking assembly 23, which includes a threaded rod 231 and a locking rod 232. The threaded rod 231 is arranged perpendicular to the axis of the clamping member 21. For the convenience of description, the two clamping members 21 are defined as the first clamping member 21 and the second clamping member 21. One end of the threaded rod 231 is rotatably connected to the first clamping member 21. A connecting hole 233 is provided on the second clamping member 21 corresponding to the threaded rod 231. The other end of the threaded rod 231 extends through the connecting hole 233 to the side of the second clamping member 21 away from the first clamping member 21. The connecting hole 233 is formed on the side of the clamping member 21 away from its own axis. Rotating the threaded rod 231 can cause the threaded rod 231 to be disengaged from the connecting hole 233. A threaded groove is formed on the locking rod 232 , and the locking rod 232 is sleeved on the end of the threaded rod 231 . Rotating the locking rod 232 can make the locking rod 232 connect to the second clamping member 21 , so that the first clamping member 21 and the second clamping member 21 hold the oil storage cylinder 11 tightly.

[0033] Reference Figure 1 and Figure 2The locking assembly 23 also includes a rocker 234, which is inserted into the locking rod 232 in a direction perpendicular to the threaded rod 231 and can slide along its own length direction, thereby facilitating the staff to rotate the locking rod 232 so that the locking rod 232 is pressed against the second clamping member 21, thereby improving the stability of the first clamping mechanism 2 in clamping the oil storage cylinder 11.

[0034] Reference Figure 1 and Figure 2 The second clamping mechanism 3 has the same structural principle as the first clamping mechanism 2 and will not be described in detail here. It is worth noting that the threaded rod 231 in the second clamping mechanism 3 is rotatably connected to the second clamping member 21, and the locking rod 232 of the second clamping mechanism 3 is grounded on the first clamping member 21. That is, the locking rod 232 of the second clamping mechanism 3 and the locking rod 232 of the first clamping mechanism 2 are respectively located on both sides of the clamping member 21 to reduce interference in the process of rotating the two locking rods 232.

[0035] Reference Figure 1 and Figure 2 A connecting assembly 4 for connecting the first clamping mechanism 2 and the second clamping mechanism 3 is provided between the first clamping mechanism 2 and the second clamping mechanism 3, and the connecting assembly 4 includes a connecting rod 41 and a fastener. A baffle 42 is welded to one end of the connecting rod 41, and the other end passes through the clamping members 21 of the first clamping mechanism 2 and the second clamping mechanism 3 in sequence, and is rotatably connected with the clamping members 21, so as to realize the rotational connection between the two clamping members 21 in the same group; and at the same time, the connection between the first clamping mechanism 2 and the second clamping mechanism 3 is realized. A thread is provided at one end of the connecting rod 41 away from the baffle 42, and a threaded hole is provided on the fastener. The fastener is threadedly sleeved on the connecting rod 41 to prevent the clamping member 21 from being separated from the connecting rod 41, thereby improving the stability of the connection between the first clamping mechanism 2 and the second clamping mechanism 3.

[0036] The implementation principle of a shock absorber separation clamp in an embodiment of the present application is as follows: during the process of repairing the shock absorber, the first clamping mechanism 2 and the second clamping mechanism 3 respectively clamp the oil storage cylinder 11 and the pressure cylinder 12 to achieve further connection between the oil storage cylinder 11 and the pressure cylinder 12, thereby reducing the occurrence of separation of the pressure cylinder 12 from the oil storage cylinder 11 during the process of pulling out the piston rod 13.

[0037] 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.
