[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment proposes a disassembly fixture to solve the problems of difficult disassembly and assembly and low efficiency of the equipment to be disassembled in the prior art. The equipment to be disassembled is a pneumatic actuator, and the component to be disassembled is a spring piston cylinder 200.

[0038] like Figure 1 As shown, the disassembly fixture includes a positioning assembly 2 and a force application assembly 1. The positioning assembly 2 is used to connect with the pneumatic actuator. The force application assembly 1 is installed on the positioning assembly 2. The force application assembly 1 includes a mounting base 11, a worm gear, a worm, and a lead screw 12. The worm gear and the worm are rotatably mounted on the mounting base 11 and mesh with each other. A through hole is provided on the mounting base 11. The lead screw 12 is slidably mounted in the through hole, and the sliding direction of the lead screw 12 is perpendicular to the rotation axis of the worm. A threaded hole is provided in the center of the worm gear. The lead screw 12 is threadedly engaged with the threaded hole. The rotation of the worm can drive the worm gear to rotate, so that the lead screw 12 reciprocates in the through hole. One end of the lead screw 12 is used to abut against the spring piston cylinder 200.

[0039] Understandably, when disassembling and assembling the pneumatic actuator, it is necessary to press the spring 100 into the spring piston cylinder 200 or remove the spring 100 from the spring piston cylinder 200. Since the spring 100 is installed in a compressed state, to prevent the spring piston cylinder 200 from being suddenly ejected by the spring 100 and causing danger, it is necessary to apply or release force steadily to the spring piston cylinder 200 during disassembly and assembly. In this embodiment, a positioning component 2 and a force application component 1 are connected. The positioning component 2 is used to connect with the pneumatic actuator. When it is necessary to disassemble or assemble the pneumatic actuator, it is only necessary to rotate the worm gear to make it engage with the worm. The worm gear rotates in the meshing mechanism. Because the lead screw 12 is engaged with the threaded hole at the center of the worm gear, when the worm gear rotates, it can cause the lead screw 12 to slide back and forth in the through hole. As a result, the lead screw 12 moves relative to the mounting base 11. One end of the lead screw 12 can abut against the spring piston cylinder 200 and move gradually, causing the spring 100 inside the spring piston cylinder 200 to gradually tighten or loosen, reducing the difficulty of disassembly and assembly. Moreover, the gradual tightening or loosening of the spring 100 can be achieved simply by rotating the worm gear, which greatly improves the efficiency of disassembly and assembly. The rotation of the worm gear driven by the worm gear also greatly improves the stability of the movement of the lead screw 12, thus enhancing safety.

[0040] Regarding the installation method of the worm gear, for example, the mounting base 11 has an annular channel on the outer periphery of the through hole, and the annular channel has two limiting surfaces spaced apart along the axial direction of the lead screw 12, with the worm gear located between the two limiting surfaces.

[0041] Regarding the installation method of the worm, for example, the mounting base 11 has a mounting hole extending in a direction perpendicular to the axis of the lead screw 12, the lead screw 12 is rotatably disposed in the mounting hole, the wall of the mounting hole has an opening, the mounting hole and the annular channel are connected at the opening, and the worm and the worm wheel mesh at the opening.

[0042] Of course, the configuration of the worm gear and worm is not limited to this. As long as the two mesh smoothly and the worm gear can effectively drive the lead screw 12 to slide, there are no further restrictions.

[0043] For example, the lead screw 12 is provided with a slider, and the wall of the through hole is provided with a groove along its length, with the slider engaging with the groove. This arrangement prevents the lead screw 12 from rotating and increases the smoothness of its sliding within the through hole. Of course, in other embodiments, other structures can be used to prevent the lead screw 12 from rotating, and no further limitations are imposed here.

[0044] Optionally, the force-applying component 1 also includes a pusher 15, which is mounted on one end of the lead screw 12 to abut against the spring piston cylinder 200. This arrangement can improve the contact stability between the lead screw 12 and the spring piston cylinder 200, thereby improving the safety of the device. In addition, the pusher 15 can also prevent the lead screw 12 from damaging the spring piston cylinder 200, thus improving the user experience.

[0045] For example, the pusher 15 is plate-shaped. This arrangement reduces the overall weight of the disassembly tooling and improves portability while ensuring stability and preventing damage to the spring piston cylinder 200.

[0046] Optionally, the force-applying assembly 1 also includes a locking member 14, which is movably mounted on the mounting base 11. The axial direction of the locking member 14 forms an angle with the axial direction of the tooth groove on the lead screw 12. The locking member 14 can move along its own axis and can move into or out of the tooth groove. This arrangement allows the lead screw 12 to be locked at any time during the disassembly and assembly of the pneumatic actuator to adjust other parts of the pneumatic actuator, improving the functional rationality of the disassembly tooling.

[0047] For example, the locking member 14 is rod-shaped and has a threaded section, and the mounting base 11 is provided with a threaded locking hole. The locking member 14 cooperates with the threaded locking hole. This arrangement can further improve the locking reliability and prevent the screw 12 from moving and causing danger when locking.

[0048] Optionally, the force application component 1 also includes a gripper 13 connected to the worm gear. In a direction perpendicular to the worm gear's axis, the outer diameter of the gripper 13 is larger than the outer diameter of the worm gear. This configuration allows the operator to rotate the worm gear with less effort, thereby improving the efficiency of disassembling the tooling and enhancing the user experience.

[0049] For example, the grip 13 has a disc-shaped radial cross-section and is coaxially arranged with the worm gear. This arrangement further facilitates the operator's rotation operation, thereby improving the user experience of disassembling the tooling.

[0050] like Figure 1 and Figure 2 As shown, optionally, the positioning component 2 includes two fixing rods 21, one end of which is movably connected to the force-applying component 1, and the other end is used to connect to the pneumatic actuator. This arrangement can reduce the weight of the positioning component 2, thereby improving the portability of the disassembly fixture, and the two fixing rods 21 can improve the force-applying stability of the force-applying component 1.

[0051] like Figure 3 and Figure 4As shown, optionally, the positioning assembly 2 also includes two adjusting members 22, which are connected one-to-one with the fixed rod 21. The force application assembly 1 also includes an adjusting rod 16, and the mounting base 11 is mounted on the adjusting rod 16. The adjusting member 22 has a first hole 221, and the adjusting rod 16 is movably inserted through the first hole 221. Understandably, the adjusting rod 16 moves in the first hole 221 of the adjusting member 22, which can adjust the up and down position of the mounting base 11, and thus adjust the contact position between the lead screw 12 and the spring piston cylinder 200. This allows for the selection of the contact position as needed according to different pneumatic actuator models, thereby improving the applicability of the disassembly fixture.

[0052] Optionally, the adjusting member 22 also has a second hole 222, which is perpendicular to and offset from the first hole 221. The fixing rod 21 is movably inserted through the second hole 222. The positioning assembly 2 also includes a plurality of locking screws 23, which have threaded sections. The adjusting member 22 has threaded holes in the direction perpendicular to the axis of the first hole 221 and in the direction perpendicular to the axis of the second hole 222. The plurality of locking screws 23 are threadedly engaged with the plurality of threaded holes one by one. One locking screw 23 abuts against the fixing rod 21, and another locking screw 23 abuts against the adjusting rod 16. Understandably, the movement of the fixing rod 21 in the second hole 222 allows the adjusting member 22 to be displaced relative to the pneumatic actuator, thereby adjusting the relative position of the mounting base 11 and the pneumatic actuator. This allows the position of the mounting base 11 to be adjusted according to the length of the spring piston cylinder 200 of different models of pneumatic actuators, thus ensuring that one end of the lead screw 12 abuts against the spring piston cylinder 200, improving disassembly and assembly efficiency, and preventing a gap between the spring piston cylinder 200 and the lead screw 12, thereby preventing the spring piston cylinder 200 from popping out and causing a hazard. Furthermore, the locking screw 23 can fix the position of the adjusting member 22 on the fixing rod 21 and also on the adjusting rod 16, preventing displacement of the adjusting member 22 that could cause the spring member 100 to pop out, further improving the reliability and safety of the disassembly tooling.

[0053] For example, two adjusting rods 16 are provided, and the mounting base 11 is installed between the two adjusting rods 16. Two first holes 221 are also provided, which are located on both sides of the second hole 222 and correspond one-to-one with the adjusting rods 16. This arrangement can improve the support strength of the adjusting rods 16 for the mounting base 11, enhance the installation stability of the mounting base 11, and thus improve the reliability of the disassembly tooling.

[0054] Optionally, the surface of the fixing rod 21 is provided with anti-slip protrusions at even intervals. This feature can further enhance the fit between the fixing rod 21 and the locking screw 23, prevent displacement of the fixing rod 21 and the adjusting member 22 that could cause the spring member 100 to pop out, and improve the safety of disassembly.

[0055] likeFigure 5 As shown, the disassembly fixture also includes multiple sets of adapters 3. Each set of adapters 3 includes two adapters 3, which are connected one-to-one with the fixing rod 21. Different sets of adapters 3 have threaded grooves 31 of different diameters, which are used to thread with the connecting parts of the pneumatic actuator. Understandably, the connecting parts of different models of pneumatic actuators have different dimensions. By setting adapters 3 with threaded grooves 31 of various diameters, the adapters 3 can be selected as needed according to the different dimensions of the connecting parts, thereby improving the applicability of the disassembly fixture.

[0056] To further enhance the flexibility of the adapter 3, for example, the adapter 3 is also provided with a threaded mounting groove 32, and the fixing rod 21 is provided with a threaded section, and the threaded mounting groove 32 is threadedly engaged with the fixing rod 21.

[0057] The disassembly process of the tooling in this embodiment is as follows:

[0058] When it is necessary to remove the spring 100 and spring piston cylinder 200 from the pneumatic actuator, fix the adapter 3 to the connector of the pneumatic actuator and connect the fixing rod 21 to the adapter 3; move the mounting base 11 up and down so that the lead screw 12 is facing the spring piston cylinder 200, and move the mounting base 11 left and right until the lead screw 12 abuts against the spring piston cylinder 200, and then tighten the locking screw 23; remove the connecting screw between the spring piston cylinder 200 and the pneumatic actuator, and the lead screw 12 begins to bear force; rotate the gripper 13 to rotate the worm gear, and then move the lead screw 12 away from the spring 100 until the spring 100 is completely relaxed, and then remove the spring piston cylinder 200 and the spring 100.

[0059] When it is necessary to install the spring 100 and the spring piston cylinder 200 on the pneumatic actuator, install one end of the spring 100 in the spring piston cylinder 200 and the other end abuts against the pneumatic actuator; fix the adapter 3 to the connector of the pneumatic actuator and connect the fixing rod 21 to the adapter 3; move the mounting base 11 up and down so that the lead screw 12 is facing the spring piston cylinder 200, and move the mounting base 11 left and right until the lead screw 12 abuts against the spring piston cylinder 200, and then tighten the locking screw 23; rotate the gripper 13 to rotate the worm gear, thereby moving the lead screw 12 towards the spring 100 until the spring piston cylinder 200 abuts against the pneumatic actuator, at which point the spring 100 is compressed into place, and then install the connecting screw between the spring piston cylinder 200 and the pneumatic actuator.
