Detailed implementation manners

[0018] The embodiments of the present application will be described below with reference to the accompanying drawings in the present application. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions of the embodiments of the present application.

[0019] Those skilled in the art of the present technology can understand that unless specifically stated, the "the" and "this" used herein may also include plural forms. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or implemented as "B", or implemented as "A and B".

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0021] In the related art, when assembling the separation spring assembly, two workers are required to cooperate. One worker compresses the spring in the separation spring assembly to the target compression length, and the other worker uses a locking member to lock it to limit the spring to maintain the target compression length, so that the pre-tightening force of the separation spring assembly reaches a predetermined value. However, such an assembly method requires the cooperation of two people to complete, with low work efficiency and high labor costs. Moreover, since the workers' hands need to directly contact the separation spring assembly during the spring compression process, the physical exertion of the personnel is relatively large. If there is a force leakage or other unexpected situation during the spring compression process, there may be a risk of injury. Therefore, this manual assembly form not only has low efficiency but also has high potential safety hazards.

[0022] The embodiment of this application provides an assembly tooling to solve the technical problems in the related art, such as low assembly efficiency, large physical exertion of manual spring extrusion, and operational risks.

[0023] An assembly tooling is used to assemble the separation spring assembly of the intermediate section. The separation spring assembly includes a base 600, a push rod 700, a spring 800, and a locking member 900. The assembly tooling includes a support base 100, a first mounting plate 200, a second mounting plate 300, a limiting guide rod 400, and a transmission member 500.

[0024] The first mounting plate 200 is arranged on the support base 100 and is configured to be detachably connected to the push rod 700. The limiting guide rod 400 penetrates the first mounting plate 200 and abuts against the support base 100, being perpendicular to the first mounting plate 200. The second mounting plate 300 is arranged in parallel with the first mounting plate 200 and is slidably matched with the limiting guide rod 400. The second mounting plate 300 is configured to be detachably connected to the base 600. An assembly hole 301 is formed on the second mounting plate 300, and the assembly hole 301 is configured to allow the locking member 900 to pass through. The transmission member 500 is used to drive the second mounting plate 300 and the first mounting plate 200 to approach each other, driving the base 600 and the push rod 700 to approach each other until the spring 800 clamped between the base 600 and the push rod 700 is compressed to the target length and then locked by the locking member 900.

[0025] In this application, by designing an assembly tooling, during assembly, since the base 600 and the ejector rod 700 of the separating spring assembly are respectively detachably connected to the second mounting plate 300 and the first mounting plate 200, during assembly, only the transmission member 500 needs to be controlled, so that the second mounting plate 300 drives the base 600 to gradually approach the ejector rod 700 until the spring 800 clamped between the base 600 and the ejector rod 700 is compressed to the target length. After that, the locking member 900 is locked with the ejector rod 700. The assembly of the separating spring assembly can be completed by only one person, which can reduce the physical consumption of the operator and effectively improve the assembly efficiency. Since the base 600 and the ejector rod 700 of the separating spring assembly are respectively limited on the second mounting plate 300 and the first mounting plate 200, the risk that the spring 800 bounces off due to the alignment deviation between the base 600 and the ejector rod 700 during the spring extrusion process or due to insufficient pressure applied by the operator is reduced. The assembly tooling of this application can effectively improve the operation safety.

[0026] Optionally, the limiting guide rod 400 includes a guiding section 410 and a limiting section 420, and the guiding section 410 and the limiting section 420 are integrally formed. The guiding section 410 passes through the guiding hole 302 of the second mounting plate 300 and is used to realize the guiding function during the movement of the second mounting plate 300 towards the first mounting plate 200. The limiting section 420 is located between the second mounting plate 300 and the first mounting plate 200. The outer diameter of the limiting section 420 is larger than the diameter of the guiding hole 302, and the length of the limiting section 420 corresponds to the target length of the spring 800.

[0027] The guiding section 410 of the limiting guide rod 400 can guide the sliding of the top plate, ensure that the axes of the ejector rod 700 and the base 600 always coincide, and ensure the qualification rate of the assembly of the separating spring assembly. Due to the diameter difference between the guiding section 410 and the limiting section 420, a limiting surface is formed between the limiting section 420 and the guiding section 410. When the second mounting plate 300 slides along the guiding section 410 until it abuts against the limiting surface, the continuous downward movement of the second mounting plate 300 can be restricted, ensuring that the spring 800 can be compressed to the target compression length in one compression without repeatedly measuring the length of the spring 800 with a vernier caliper, greatly improving the compression accuracy and compression efficiency of the spring 800.

[0028] Optionally, the limit guide rod 400 further includes a positioning section 430 disposed at one end of the limit section 420 away from the guiding section 410. The positioning section 430 is inserted into the positioning hole 204 of the first mounting plate 200, and the positioning hole 204 is used for radially limiting the positioning section 430. The positioning section 430 and the first mounting plate 200 are in an inserted and matched form, thereby restricting the radial movement of the limit guide rod 400. Optionally, the positioning section 430 and the guiding section 410 have the same diameter, so that there is a limit step between the positioning section 430 and the limit section 420, and the limit step abuts against one side of the first mounting plate 200 facing the second mounting plate 300, thereby axially limiting the limit guide rod 400.

[0029] Optionally, the first mounting plate 200 is provided with a first limiting hole 201 for limiting the assembly ring 720 of the ejector rod 700. The first surface of the second mounting plate 300 close to the first mounting plate 200 is provided with a second limiting groove 303 matching the bottom of the base 600 and an assembly hole 301 penetrating the center of the bottom of the second limiting groove 303. The assembly hole 301 is configured to allow the locking member 900 to pass through.

[0030] The first limiting hole 201 is used for axially and radially limiting the ejector rod 700, and the second limiting groove 303 is used for axially and radially limiting the base 600, thereby preventing the base 600 and the ejector rod 700 from shifting during the compression of the spring 800 and reducing the safety hazard during the compression of the spring 800. In the form of inserted and matched, it is convenient for the installation and disassembly of the ejector rod 700 and the base 600 on the assembly tooling.

[0031] Optionally, the first limiting hole 201 is a hexagonal hole, which is used to cooperate with the locking nut 730 on the side of the assembly ring 720 away from the spring 800 to limit the radial movement and circumferential rotation of the ejector rod 700.

[0032] Optionally, a plurality of first limiting holes 201 are arranged circumferentially around the first mounting plate 200, and a plurality of assembly holes 301 are arranged corresponding to the first limiting holes 201. So that multiple separated spring assemblies can be assembled simultaneously in one working step, further improving the working efficiency.

[0033] Optionally, this application takes the example that there are three first limiting holes 201 arranged circumferentially around the first mounting plate 200, and the assembly holes 301 and the second limiting grooves 303 are arranged corresponding to the first limiting holes 201 circumferentially around the second mounting plate 300. The assembly tooling of this application can assemble three separated spring assemblies simultaneously, which can effectively improve the assembly efficiency of the separated spring assemblies.

[0034] Optionally, there are also three positioning holes 204, and the first limiting hole 201 and the positioning holes 204 are arranged alternately in the circumferential direction around the first mounting plate 200, so that the separation spring assembly and the limiting guide rod 400 are evenly arranged in the circumferential direction of the assembly tooling, making the structure of the assembly tooling more stable. When the second mounting plate 300 slides downward, it always remains horizontal, ensuring that the axes of the ejector rod 700 and the base 600 always coincide, and improving the assembly qualification rate of the separation spring assembly.

[0035] Optionally, the transmission member 500 includes a fastening bolt 510 and a fastening nut 520 that is threadedly engaged with the fastening bolt 510. The head of the fastening bolt 510 is detachably connected to the first mounting plate 200, the rod body of the fastening bolt 510 passes through the second mounting plate 300, and the fastening nut 520 abuts against the second surface of the second mounting plate 300 away from the first mounting plate 200.

[0036] By screwing the fastening nut 520, the relative position of the fastening nut 520 and the rod body of the fastening bolt 510 is adjusted, so that the second mounting plate 300 can be gradually pressed closer to the first mounting plate 200, driving the ejector rod 700 and the base 600 to approach each other, converting the torque received by the fastening nut 520 into the pressure of the radially compressed spring 800, causing the spring 800 to be gradually compressed until the spring 800 is compressed to the target compression length.

[0037] Moreover, due to the threaded connection form of the fastening nut 520 and the fastening bolt 510, even if the force applied to the fastening nut 520 is released, the spring 800 will not rebound, enabling the spring 800 to be stably limited at the target compression length and effectively reducing the probability of the operator being injured by the rebound of the spring 800. Optionally, a backing plate 530 is provided between the fastening nut 520 and the second mounting plate 300, so that the fastening nut 520 abuts against the backing plate 530.

[0038] By providing the backing plate 530 between the fastening nut 520 and the second mounting plate 300, the contact area between the fastening nut 520 and the second mounting plate 300 is increased, the force-bearing area for the fastening nut 520 to transmit pressure is increased, and the possible pressure deformation of the second mounting plate 300 caused by the small force-bearing area is reduced.

[0039] Optionally, the transmission member 500 of the present application can also use a hydraulic power drive system, which can further save manpower and further improve the assembly efficiency.

[0040] Optionally, a third limiting groove 202 matching the head of the fastening bolt 510 and a first through hole 203 that cooperates with the rod body of the fastening bolt 510 and communicates with the third limiting groove 202 are provided on the surface of the first mounting plate 200 away from the second mounting plate 300.

[0041] The third limiting groove 202 limits the head of the fastening bolt 510, thereby restricting the circumferential rotation of the fastening bolt 510, ensuring that by screwing the fastening nut 520, the fastening nut 520 can move up and down along the rod body of the fastening bolt 510. The inner diameter of the first through hole 203 matches the diameter of the rod body of the fastening bolt 510, thereby restricting the radial movement of the fastening bolt 510.

[0042] Optionally, the axial direction of the assembly tooling of the present application can be vertical or horizontal. When the axial direction of the assembly tooling is the vertical axial direction, the second mounting plate 300 is arranged parallel above the first mounting plate 200, such that the second mounting plate 300 serves as the top plate and the first mounting plate 200 serves as the bottom plate. The base 600 of the separation spring assembly is limited on the lower surface of the top plate, and the assembly ring 720 of the ejector rod 700 is limited on the upper surface of the bottom plate. The limiting guide rod 400 is arranged vertically, and the top plate can slide vertically along the guiding section 410. By driving the transmission member 500, the top plate is pressed to gradually move downward along the guiding section 410, and the ejector rod also gradually moves downward, so that the spring clamped between the assembly ring 720 and the base 600 is gradually compressed. When the lower surface of the top plate abuts against the limiting surface, the top plate cannot continue to move downward, and the spring 800 is compressed to the target compression length.

[0043] When the axial direction of the assembly tooling is the horizontal axial direction, the first mounting plate 200 is arranged on the left or right side of the second mounting plate 300, the limiting guide rod 400 is arranged horizontally, and the second mounting plate 300 moves horizontally along the guiding section 410.

[0044] The present application will be described by taking the case where the axial direction of the assembly tooling is the vertical axial direction as an example. Optionally, the support base 100 includes a tray 110 and a plurality of legs 120. The tray 110 is annular, and the plurality of legs 120 are arranged at intervals around the circumference of the tray 110. A stepped groove 111 matching the first mounting plate 200 is provided at the inner edge of the tray 110, thereby radially limiting the first mounting plate 200.

[0045] Optionally, a gasket 130 is provided at one end of each leg 120 away from the tray 110. The gasket 130 includes but is not limited to a rubber gasket, so as to increase the frictional resistance between the support base 100 and the workbench surface, reduce the deviation of the axis of the ejector rod 700 and the base 600 caused by the displacement of the support base 100, and thus the operation risk, which is beneficial to ensuring the smooth progress of the assembly work.

[0046] Optionally, the first mounting plate 200 and the second mounting plate 300 have the same shape, and the transmission member 500 is arranged at the centers of the second mounting plate 300 and the first mounting plate 200.

[0047] The first mounting plate 200 includes a first mounting area 210 and a second mounting area 220 that are alternately arranged around its circumference. The first mounting area 210 includes an arc edge centered on the transmission member 500, and the second mounting area 220 includes a straight edge. The first limiting hole 201 is arranged within the first mounting area 210, and the limiting guide rod 400 is arranged within the second mounting area 220.

[0048] By respectively setting the shapes of the first mounting area 210 and the second mounting area 220, the first mounting area 210 protrudes outward relative to the second mounting area 220. The shapes of the first mounting plate 200 and the second mounting plate 300 are non-circular, thereby avoiding relative rotation between the first mounting plate 200 and the tray 110, achieving axial limiting of the first mounting plate 200, further reducing the operation risk during the assembly process, and effectively improving the assembly efficiency.

[0049] Moreover, the area of the first mounting area 210 is larger than that of the second mounting area 220, thereby providing a larger mounting space for the separation spring assembly, facilitating the assembly of multiple separation spring assemblies in one working step, and improving the assembly efficiency. The reduction in the area of the second mounting area 220 is beneficial to reducing the overall volume and weight of the assembly tooling of the present application.

[0050] Based on the same inventive purpose, an embodiment of the present application provides an assembly system, including the assembly tooling of the above embodiment and the separation spring assembly of the inter-pole section.

[0051] The above-mentioned assembly tooling includes a support base 100, a first mounting plate 200, a second mounting plate 300, a limiting guide rod 400, and a transmission member 500.

[0052] The separation spring assembly includes a base 600, a push rod 700, a spring 800, and a locking member 900. The base 600 includes a cylindrical portion 610 and an assembly seat 620 provided at one end of the cylindrical portion 610. The push rod 700 includes a rod portion 710 and an assembly ring 720 provided on the outer circumference of a partial section of the rod portion 710. The rod portion 710 of the push rod 700 is inserted into the cylindrical portion 610, and the spring 800 is sleeved outside the cylindrical portion 610 and is arranged between the assembly seat 620 and the assembly ring 720. A limiting groove for limiting the spring 800 is provided on the assembly seat 620.

[0053] The push rod 700 is detachably connected to the first mounting plate 200, and the base 600 is detachably connected to the second mounting plate 300. The second mounting plate 300 and the first mounting plate 200 are used to approach each other under the drive of the transmission member 500, driving the base 600 and the push rod 700 to approach each other until the spring 800 clamped between the base 600 and the assembly ring 720 is compressed to the target length and is locked by the locking member 900.

[0054] Optionally, the rod portion 710 of the ejector rod 700 includes a first rod segment 711 and a second rod segment 712. The diameter of the first rod segment 711 is smaller than that of the second rod segment 712. The first rod segment 711 is integrally formed at one end of the second rod segment 712, or the second rod segment 712 is a hollow rod, and the first rod segment 711 is inserted and fitted inside the second rod segment 712. The assembly ring 720 abuts against the stepped position formed by the first rod segment 711 and the second rod segment 712. External threads are machined on the outside of the first rod segment 711, and the relative position between the assembly ring 720 and the rod portion 710 is locked by a locking nut 730 that is threadedly engaged with the first rod segment 711.

[0055] Optionally, the locking member 900 includes a pressing rod 910. Internal threads are provided on the inner wall of the pressing rod 910, and external threads are provided on the outer wall of the rod portion 710 of the ejector rod 700. The pressing rod 910 is configured to be inserted into the cylindrical portion 610 and threadedly connected to the rod portion 710 when the spring 800 is compressed to the target length.

[0056] Optionally, the pressing rod 910 includes a hollow rod segment 911. A second through hole matching the outer diameter of the hollow rod segment 911 is formed in the assembly seat 620. The inner diameter of the hollow rod segment 911 is larger than the outer diameter of the second rod segment 712, and internal threads are machined on the inner side wall of the hollow rod segment 911, and external threads are machined on the outside of the second rod segment 712, so that the hollow rod segment 911 is threadedly connected to the second rod segment 712. After the spring 800 reaches the target length, the deformation of the spring 800 is restricted to ensure the accuracy when the spring 800 is compressed.

[0057] Optionally, the pressing rod 910 further includes a retaining ring 912 provided at one end of the hollow rod segment 911. The diameter of the retaining ring 912 is larger than the diameter of the second through hole and smaller than the inner diameter of the assembly hole. When the retaining ring 912 abuts against the assembly seat 620, the relative positions of the pressing rod 910, the ejector rod 700, the base 600, and the spring 800 are restricted.

[0058] The working principle of the embodiment of the present application includes: Before assembly, the assembly tooling of the present application is placed vertically on the workbench surface, and the fastening nut 520 and the second mounting plate 300 are removed in sequence. Then, the first rod segment 711 of the ejector rod 700 of the separating spring assembly is passed through the first limiting hole, so that the locking nut 730 is embedded in the first limiting hole 201. The assembly seat 620 of the base 600 is embedded in the second limiting groove 303 of the second mounting plate 300, and the spring 800 is sleeved outside the cylindrical portion 610 to complete the temporary limiting of the separating spring assembly by the assembly tooling. Then, the second mounting plate 300 is slidably connected to the limiting guide rod 400 and the rod body of the fastening bolt 510 again, and then the spacer plate 530 and the fastening nut 520 are installed in sequence to complete the assembly of the assembly tooling. At this time, the spring 800 is clamped between the assembly seat 620 and the assembly ring 720 and is in a relaxed state.

[0059] During assembly, by screwing the fastening nut 520, the torque of the fastening nut 520 is converted into a pressure that axially compresses the spring 800, causing the second mounting plate 300 to move along the guiding section 410, driving the base 600 to gradually approach the ejector rod 700 until the lower surface of the second mounting plate 300 abuts against the limiting surface of the limiting guide rod 400. At this time, the spring 800 is compressed to the target length. Due to the threaded connection form of the fastening nut 520 and the fastening bolt 510, even if the force applied to the fastening nut 520 is released, the spring 800 will not rebound, enabling the spring 800 to be stably limited at the target compression length and effectively reducing the probability of operators being injured due to accidental rebound of the spring 800. Subsequently, the pressing rod 910 is passed through the assembly hole 301 from top to bottom and threadedly connected to the second rod section 712 of the ejector rod 700 to fix the relative positions of the ejector rod 700, the base 600, and the spring 800.

[0060] After the assembly is completed, the fastening nut 520 and the second mounting plate 300 are removed again, and the separated spring assembly is taken off, and the assembly of the separated spring assembly is completed.

[0061] In summary, the beneficial technical effects brought by the technical solution provided by the embodiment of the present application include: The base 600 and the ejector rod 700 of the separated spring assembly are respectively detachably connected to the second mounting plate 300 and the first mounting plate 200 of the assembly tooling. During assembly, only the transmission member 500 needs to be controlled to cause the second mounting plate 300 to drive the base 600 to gradually approach the ejector rod 700 until the spring 800 clamped between the base 600 and the ejector rod 700 is compressed to the target length, and then the locking member 900 is locked with the ejector rod 700. The assembly of the separated spring assembly can be completed by only one person, which can effectively improve the assembly efficiency and reduce the safety risk caused by axial misalignment between the base 600 and the ejector rod 700 during the operation process.

[0062] The guiding section 410 of the limiting guide rod 400 can guide the sliding of the top plate to ensure that the axes of the ejector rod 700 and the base 600 always coincide. A limiting surface is formed between the limiting section 420 and the guiding section 410, which can limit the further downward movement of the second mounting plate 300, ensuring that the spring 800 can be compressed to the target compression length in one compression without repeatedly measuring the length of the spring 800 using a vernier caliper, greatly improving the compression accuracy and compression efficiency of the spring 800.

[0063] Using the fastening nut 520 and the fastening bolt 510 as the driving member 500, the torque received by the fastening nut 520 is converted into a pressure that radially compresses the spring 800, causing the spring 800 to be gradually compressed. Even if the force applied to the fastening nut 520 is released, the spring 800 will not rebound, enabling the spring 800 to be stably limited at the target compression length and effectively reducing the probability of operators being injured due to the rebound of the spring 800.

[0064] By respectively setting the shapes of the first installation area 210 and the second installation area 220, the first installation area 210 protrudes outward relative to the second installation area 220, and the shapes of the first installation plate 200 and the second installation plate 300 are non-circular, so that relative rotation between the first installation plate 200 and the tray 110 can be avoided, axial limit of the first installation plate 200 can be realized, the operation risk during the assembly process can be further reduced, and the assembly efficiency can be effectively improved.
