Description

Technical Field

[0001] This invention relates to the field of reciprocating machine maintenance tools, specifically a quick disassembly and assembly tool for reciprocating machines. Background Technology

[0002] Because of its simple structure and few parts, the recoil mechanism is usually disassembled and assembled manually using general tools during routine repairs. However, for recoil mechanisms that use recoil springs with medium to large elastic coefficients, manual disassembly and assembly is inefficient and can easily cause physical injury to the repairman.

[0003] The sudden release of the spring force and the uncontrollable trajectory of the spring remain the main causes of personal injury. Although current maintenance work processes employ measures such as wearing protective gear, multi-person cooperation in disassembly and assembly, and using universal tools to limit injuries, these methods still cannot fundamentally solve the problem.

[0004] Chinese Patent CN219562963U discloses a recoil spring disassembly tool, which effectively solves the disassembly of the recoiler of this type and has high safety. However, the type of recoiler it disassembles is specific. The recoiler described in this patent consists of a guide sleeve 51, a slide cylinder 53, a guide rod 54, a stop head 55, a retaining ring 56, and a recoil spring 57. The recoil spring 57 is installed between the end of the guide sleeve 52 and the stop head 55. The stop head 55 can move on the guide rod 54. The slide cylinder 53 is inserted into the guide sleeve 51, and the guide rod 54 is inserted into the slide cylinder 53. The end of the guide rod 54 extends out of the slide cylinder 53 and is connected to the stop head 55 through the retaining ring 56. The disassembly of this type of recoiler requires first pressing the end of the guide rod 54 with the retaining ring 56 out of the stop head 55, that is, compressing the stop head 55 and the recoil spring 57 together, and then removing the retaining ring 56 before the disassembly of the various components of this type of recoiler can be completed. The patented technology involves compressing the stop head 55 with the designed bearing cylinder 1, which in turn compresses the recoil spring 57, exposing the retaining ring 56 for disassembly. This patent can only be used for disassembling this type of recoil machine and cannot be universally applicable. For example, if the stop head 55 is directly connected to the guide rod 54 without being connected by the retaining ring 56, the patented technology cannot be used to disassemble it.

[0005] Therefore, it is urgent to develop a fast, efficient, safe, and low-cost universal tool for disassembling and assembling recoilers. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a quick assembly and disassembly tool for a recoiling machine.

[0007] A quick assembly / disassembly tool for a reciprocating machine includes a fixed limiting outer sleeve with one end sealed and a movable limiting inner sleeve. The limiting inner sleeve can be inserted into the limiting outer sleeve. The inner sleeve has an insertion port on its wall at the end away from the limiting outer sleeve and is equipped with a detachable positioning buckle. The limiting inner sleeve is equipped with an inner sleeve moving device for controlling the movement of the limiting inner sleeve, a positioning device for positioning the limiting inner sleeve after movement, and a guiding sliding device for guiding the movement of the limiting inner sleeve.

[0008] Furthermore, the inner sleeve moving device is a vertical handle disposed on the limiting inner sleeve near the insertion port.

[0009] Furthermore, the positioning device includes a positioning rod, one end of which is hinged to the top side of the unsealed end of the limiting outer sleeve, and the other end of which is provided with a hook that can be hooked onto a vertical handle.

[0010] Furthermore, the guide sliding device includes a base located on the bottom side of the limiting outer sleeve, and the top of the base is provided with several axially vertical guide rail bearings on both sides of the limiting outer sleeve. The limiting inner sleeve is provided with guide rails that cooperate with the guide rail bearings on both sides.

[0011] Furthermore, the guide rail is provided with a track groove, and the track bearing rotates within the track groove to ensure that the guide rail moves in a straight line.

[0012] Furthermore, the sealing end of the limiting outer sleeve is sealed by a vertical plate that is fixedly connected to the base.

[0013] Furthermore, the positioning buckle includes a handle, one end of which is connected to two parallel insert rods.

[0014] Furthermore, a limiting rod for assisting in the placement of the reciprocating machine is also provided at the axis of the limiting outer sleeve.

[0015] Furthermore, a pressure sensor is provided at the sealing end inside the limiting outer sleeve, and a digital display is provided outside the limiting outer sleeve, through which the data information measured by the pressure sensor is displayed.

[0016] Advantages of this invention: This invention has a reasonable structure. By compressing the recoil spring, the detachable stop head end is separated from the recoil spring for easy disassembly, thereby making the recoil machine easy to disassemble. Furthermore, by directly compressing the recoil spring, its versatility can be improved, making it easy to disassemble various types of recoil machines.

[0017] This invention can avoid maintenance personnel from directly contacting the control spring, ensuring the safety of maintenance personnel to the greatest extent, while further improving the disassembly and assembly efficiency of the return mechanism;

[0018] This invention allows for the assembly and disassembly of recuperative machines of different lengths by traveling different distances along the guide rail, and enables the measurement and display of the pressure torque of the recuperative spring. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 The present invention discloses a quick assembly and disassembly tool for a reciprocating machine, comprising a fixed limiting outer sleeve 1 with one end sealed and a movable limiting inner sleeve 2. The limiting inner sleeve 2 can be inserted into the limiting outer sleeve 1. The inner sleeve 2 has an insertion port 3 on the sleeve wall away from the limiting outer sleeve 1 and is equipped with a detachable positioning buckle 4. The limiting inner sleeve 2 is equipped with an inner sleeve moving device for controlling the movement of the limiting inner sleeve 2, a positioning device for positioning the limiting inner sleeve 2 after movement, and a guiding sliding device for guiding the movement of the limiting inner sleeve.

[0032] The inner sleeve moving device is a vertical handle 5 located on the limiting inner sleeve 2 near the insertion port 3.

[0033] The positioning device includes a positioning rod 6, one end of which is hinged to the top side of the unsealed end of the limiting outer sleeve 1, and the other end of the positioning rod 6 is provided with a hook 7, which can be hooked onto the vertical handle 5.

[0034] The guide sliding device includes a base 8 located on the bottom side of the limiting outer sleeve 1. The top of the base 8 is provided with several axially vertical guide rail bearings 9 on both sides of the limiting outer sleeve 1. The limiting inner sleeve 2 is provided with guide rails 10 that cooperate with the guide rail bearings 9 on both sides.

[0035] The guide rail 10 is provided with a track groove 11, and the track bearing 9 rotates in the track groove 11 to ensure that the guide rail 10 moves in a straight line on the base 8.

[0036] The sealing end of the limiting outer sleeve 1 is sealed by a vertical plate 12 that is fixedly connected to the base 8.

[0037] like Figure 3 As shown, the positioning buckle 3 includes a handle 401, one end of which is connected to two parallel insert rods 402. The two insert rods 402 are inserted into both sides of the guide rod of the recoil mechanism to facilitate the compression of the recoil spring.

[0038] The limiting sleeve 1 is also provided with a limiting rod 13 at the axis for assisting in the placement of the recoil machine, which can be used to limit the guide rod of the hollow recoil machine and is installed inside the limiting sleeve 1.

[0039] A pressure sensor 14 is provided at the sealing end inside the limiting outer sleeve, and a digital display 15 is provided outside the limiting outer sleeve. A main controller and power supply are configured, located inside the base 8. The main controller is electrically connected to the power supply, pressure sensor 14, and digital display 15. When the recoil spring is compressed, one end of the recoil guide rod inside the limiting outer sleeve 1 acts on the pressure sensor 14. The detected data is processed by the main controller and then displayed on the digital display 15. Figure 4 As shown.

[0040] Application Example 1: Disassembly of the reciprocating machine described in Chinese Patent Publication No. CN219562963U

[0041] like Figure 5 As shown, the recoiling machine is placed inside the limiting outer sleeve 1 and the limiting inner sleeve 2. One end of the recoiling machine with a retaining ring 56 is located inside the limiting inner sleeve 2, and the other end is located inside the limiting outer sleeve 1. Since this type of guide rod 54 is a new type, a limiting rod 13 can be added. The pressure sensor 14 is located on one side of the limiting rod 13.

[0042] During operation, the two insert rods 402 of the positioning buckle 4 are placed on both sides of the guide rod 54 through the insertion port 3 and fastened between the stop head 55 and the return spring 57. The vertical handle 5 is operated and the guide rail 10 and guide rail bearing 9 are used to move towards the limiting outer sleeve 1. After moving to a suitable position, the stop head 55 to be disassembled is exposed. The hook 7 at one end of the positioning rod 6 is used to intercept and prevent rebound. The exposed stop head 55 and retaining ring 56 can then be disassembled. After the stop head and retaining ring are disassembled, the vertical handle is held and the hook 7 is opened to release them slowly. After the release is completed, the return machine can be removed to disassemble the return spring, guide rod and other components.

[0043] Application Implementation 2: Disassembly of a recoiler where the stop head is not connected to the recoiler guide rod via a retaining ring.

[0044] like Figure 6 As shown, the guide rod of the recoiling machine is a non-hollow guide rod, so the limit rod 13 does not need to be set. The stop head 55 is directly connected to the guide rod 54 without the retaining ring 56. If it is threaded, the stop head 55 will not move on the guide rod 54. The disassembly process of the stop head 55 and the entire recoiling machine is similar to that in application example 2.

[0045] Regardless of the connection method between the stop and the guide rod of the recoil machine, the present invention can achieve disassembly by compressing the recoil spring, exposing the stop to be disassembled and separating it from the recoil spring, thereby achieving the disassembly of the entire recoil machine, and has strong versatility.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
