Description

Technical Field

[0001] This utility model belongs to the technical field of tracked chassis component production equipment, and relates to a tensioning cylinder assembly fixture. Background Technology

[0002] The tensioning cylinder is a key component in a hydraulic system used to adjust the tension of chains or tracks. Its structure is as follows: Figure 2 As shown, the assembly includes a hydraulic cylinder 11, a spring 12, a ring fork 13, and a nut 14. During assembly, the spring 12 and the ring fork 13 are fitted onto the hydraulic cylinder 11, and then the spring 12 is compressed so that the threaded rod on the hydraulic cylinder 11 extends to the mounting hole of the ring fork 13. Finally, the nut 14 is used to lock the ring fork 13, so that the above components form a whole.

[0003] However, since the spring 12 on the tensioning cylinder 11 is generally quite large, if the force deviates slightly during the compression of the spring 12, the spring 12 and other parts will spring out and fly out, causing serious injury to the assembly personnel. Therefore, there is a great safety hazard. Utility Model Content

[0004] To address the issue of low safety in existing technologies, this invention provides an assembly fixture for a tensioning cylinder 11 to protect the operational safety of assembly workers and reduce employment risks.

[0005] The purpose of this utility model can be achieved through the following technical solution: a tensioning cylinder assembly fixture, characterized in that the fixture includes a rectangular cabinet, a hydraulic cylinder is vertically fixed at the top of the cabinet, the push rod of the hydraulic cylinder extends through the top plate of the cabinet into the cabinet body, a pressure plate is fixed at the bottom of the push rod, and a protective cage is welded to the bottom of the pressure plate; a countersunk hole is provided at the bottom of the cabinet body directly below the push rod.

[0006] Preferably, the cabinet has an opening at the front end, and a protective door is provided at the lower part of the opening on the cabinet; the protective door is provided with a handle with a latch.

[0007] Preferably, the protective cage includes several connecting rods and protective rings distributed on the lower surface edge of the pressure plate, with both ends of each connecting rod welded between the pressure plate and the protective ring.

[0008] The advantages of this utility model are:

[0009] Safe and reliable: The semi-enclosed cabinet, protective cage, and countersunk holes provide multiple layers of protection, effectively preventing parts from flying and ensuring the safety of assembly workers. Attached Figure Description

[0013] In the diagram, 11 is the hydraulic cylinder; 111 is the connecting assembly; 12 is the spring; 13 is the fork ring; 14 is the nut; 21 is the cabinet; 22 is the hydraulic cylinder; 23 is the push rod; 24 is the pressure plate; 25 is the protective cage; 26 is the countersunk hole; and 27 is the protective door. Detailed Implementation

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 3 As shown, a tensioning cylinder assembly fixture includes a rectangular cabinet 21. A hydraulic cylinder 22 is vertically fixed at the top of the cabinet 21. The push rod 23 of the hydraulic cylinder 22 extends through the top plate of the cabinet 21 and into the cabinet 21. A pressure plate 24 is fixed at the bottom of the push rod 23. A protective cage 25 is welded to the bottom of the pressure plate 24. A countersunk hole 26 is provided at the bottom of the inner part of the cabinet 21 directly below the push rod 23.

[0016] like Figure 3 As shown, when assembling the tensioning cylinder using this tooling, we first need to place the cylinder 11 vertically inside the cabinet 21, so that the connecting component 111 at the bottom of the cylinder 11 is inserted into the countersunk hole 26. Then, the spring 12 and the fork ring 13 are both sleeved on the cylinder 11. Next, the hydraulic cylinder 22 is activated, so that its push rod 23 extends outward, bringing the pressure plate 24 down, thereby pressing against the fork ring 13 and compressing the spring 12. Finally, the threaded rod on the cylinder 11 extends to the mounting hole of the ring fork 13. Finally, after ensuring that the position of each component is stable, the worker's hand goes into the protective cage 25 and installs the nut 14 on the expansion steel to lock the fork ring 13. This completes the assembly operation of the tensioning cylinder.

[0017] In this fixture, the inner bottom of the cabinet 21 has a countersunk hole 26, which allows the connecting component 111 at the bottom of the hydraulic cylinder 11 to be inserted into it, thereby achieving the positioning of the hydraulic cylinder 11 and the relative restriction of its bottom, thus restricting the tensioning hydraulic cylinder from below; secondly, the bottom of the pressure plate is provided with a protective cage 25, which can restrict the hydraulic cylinder 11 from above; in this way, this fixture can restrict and protect the tensioning hydraulic cylinder in both the upper and lower directions, thereby effectively preventing the splashing of parts due to the deviation of the force during the compression of the spring 12, thus ensuring the safety of the assembly operation.

[0018] like Figure 1 and Figure 3As shown, the front end of the cabinet 21 is open, and a protective door 27 is provided at the lower part of the opening on the cabinet 21; the protective door 27 is equipped with a handle with a lock. During the assembly of the tensioning cylinder, at the initial stage of the downward movement of the pressure plate, the protective door 27 needs to be opened. The operator needs to hold the cylinder 11, spring 12, and fork ring 13 inside the cabinet 21. After the pressure plate contacts the top of the fork ring 13 and the spring 12 is slightly pressed down, the operator should then step out of the cabinet 21 and close the protective door 27, allowing the pressure plate to continue pressing down until it is fully depressed. This ensures that the entire process of pressing down the spring 12 is carried out in a relatively enclosed environment, further guaranteeing the safety of the assembly. The protective door 27, which is only closed at the lower part of the opening of the cabinet 21, not only further guarantees the safety of the assembly but also allows the operator to reach into the cabinet 21 to install the nut 14 after the pressure is fully depressed.

[0019] Preferably, the protective cage 25 includes several connecting rods and protective rings distributed on the lower surface edge of the pressure plate 24, with both ends of each connecting rod welded between the pressure plate 24 and the protective ring. The protective cage 25 structure composed of connecting rods and protective rings not only restricts and protects the upper part of the hydraulic cylinder 11, but also facilitates the observation of the top of the tensioning cylinder and the installation of the nut 14 by the operators.

[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
