Description
Technical Field
[0001] The invention relates to the technical field of lock nail assembly, and in particular to an assembly tool and method for a spring lock nail assembly. Background Art
[0002] In some application environments, electronic equipment needs to be quickly installed and disassembled, such as in airborne environments. The spring lock pin assembly is a commonly used quick lock assembly on the panel of electronic equipment. The spring lock pin assembly consists of a lock pin, a spring, and a sleeve. The current installation method is to first use a riveting tool to rivet the sleeve on the panel, put the spring into the sleeve, and then pass the lock pin through the spring and sleeve, and then use a closing tool to close the sleeve inward. This assembly method mainly has the following three problems:
[0003] (1) It is necessary to make one set of riveting tooling and one set of closing tooling. Both tools are simple tools that are hammered manually, which requires high skills of the operator. Otherwise, it is difficult to ensure quality consistency.
[0004] (2) Two assembly steps are required to complete, and the assembly efficiency is low.
[0005] (3) Since the surface of the equipment panel has been sprayed with paint, the paint layer is easily damaged by clamping twice and manual knocking.
[0006] It can be seen that the current spring lock nail assembly solution still has room for improvement and needs to be optimized to improve assembly efficiency and reduce assembly procedures. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the prior art. Summary of the invention
[0007] In order to overcome at least one of the defects mentioned above, the present invention proposes an assembly tool and method for a spring lock nail assembly, which can achieve simultaneous completion of the riveting and closing processes by adjusting the stamping structure, thereby saving operating procedures and improving assembly efficiency.
[0008] In order to achieve the above-mentioned purpose, the assembly work disclosed in the present invention can adopt the following technical solutions:
[0009] A tool for assembling a spring lock nail assembly comprises a workbench, on which a riveting assembly for riveting operations is formed, the riveting assembly comprising a riveting top head and a supporting member that cooperate with each other, a riveting forming surface being formed on the riveting top head; a closing assembly opposite to the riveting assembly is also arranged above the riveting assembly, the closing assembly comprising a closing punch and a guide cylinder that cooperate with each other, a closing protrusion being formed on the closing punch; a guide structure is arranged on the workbench, and when the closing assembly approaches the riveting assembly along the guide structure, the riveting and closing of the spring lock nail assembly are synchronously completed.
[0010] The assembly tool disclosed above provides a support surface through a workbench as a load-bearing structure during assembly; the rivet assembly is located below the closing assembly, and the rivet head of the rivet assembly is sleeved with a support member. When the panel fits the support member and moves down along the rivet head, the rivet head passes through the rivet hole and contacts and presses against the sleeve to be riveted. When the force of the rivet head on the sleeve reaches the rivet requirement, the sleeve is pressed and deformed to achieve rivet. The closing guide cylinder is located below the closing protrusion. When the closing punch and the closing guide cylinder move down, the sleeve to be closed enters the closing guide cylinder and presses against the closing punch. When the force of the closing punch on the sleeve reaches the closing requirement, the sleeve is pressed and deformed to achieve closing. The whole process only requires the closing assembly to be pressed down close to the rivet assembly to achieve simultaneous rivet and closing, thereby completing the original two sets of operations on one device, which can save the steps of operation and improve the efficiency of rivet and closing.
[0011] Furthermore, the cooperation between the rivet assembly and the workbench can be realized through a variety of schemes, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: a rivet installation groove is formed on the workbench, the rivet head is arranged in the rivet installation groove, the support member is arranged at the notch of the rivet installation groove, and the support member is formed with a rivet hole for the rivet head to pass through, and a support surface for cooperating with the support panel of the locking nail assembly. When the above scheme is adopted, the rivet head includes a fixing part and a head part, the fixing part fits the inner bottom of the rivet installation groove and is fixed by a fastener; the head part extends toward the notch of the rivet installation groove, and the head part is provided with a receiving channel for accommodating the locking nail when performing the rivet closing operation.
[0012] Furthermore, in order to maintain a good fit between the panel and the support member and the rivet head, and to better perform the rivet operation, the structure of the rivet assembly can be constructed in a variety of forms, and its structure is not limited to a single one. Here, an optimization is performed and one of the feasible options is proposed: a rivet elastic member is provided between the support member and the rivet head, and the rivet elastic member applies an elastic support force to the support member; a lower pressure ring is also provided at the notch of the installation groove, and the lower pressure ring is used to cooperate with the support member and prevent the support member from detaching from the installation groove. When the above scheme is adopted, the rivet elastic member can be a spring, which applies an elastic force to the support member to keep the support member and the panel in close contact, thereby synchronously moving downward to realize the rivet action; the lower pressure ring applies a clamping force from top to bottom to limit the support member from moving upward to leave the rivet installation groove, and keep the overall structure of the rivet assembly stable and reliable.
[0013] Furthermore, the closing component is opposite to the riveting component, and can close the mouth while riveting. A variety of schemes can be used as the composition of the closing component, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the closing component includes a lifting plate, and the closing punch and the guide cylinder are integrated on the lifting plate. When the lifting plate moves down, the closing punch approaches the guide cylinder and performs the closing action. When the above scheme is adopted, the closing punch can cooperate with the automatic stamping structure or the manual stamping structure. When the downward pressing action is performed, the closing punch can perform a stamping and closing operation on the sleeve to be riveted and closed.
[0014] Furthermore, in order to improve the overall structural reliability of the closing punch and enable rapid resetting after stamping and closing, the structure can be optimized and improved. The structure is not limited to a single one. Here, optimization is performed and one of the feasible options is proposed: a closing elastic member is provided between the closing punch and the guide cylinder, and the closing elastic member applies elastic force to the guide cylinder and the closing punch, so that the closing punch returns to the initial position after the closing action is completed. When the above scheme is adopted, the closing elastic member can be a spring, forming a certain axial gap between the closing punch and the guide cylinder. When the closing punch is pressed down, the elastic gap is reduced, and the spring provides a supporting force to keep the axial gap between the closing punch and the guide cylinder back to its original size.
[0015] Furthermore, the closing assembly is installed on the lifting plate, and the specific installation method is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: a closing installation hole is formed on the lifting plate, a guide cylinder is arranged at the opening of the closing installation hole facing the riveting assembly, and a closing punch extends from the other opening of the closing installation hole and is fixed by the upper pressure ring. When the above scheme is adopted, the guide cylinder is fixedly installed at the closing installation hole by fasteners, and the upper pressure ring is connected to the closing installation hole by fasteners, and a transverse limiting flange is formed at the part where the closing punch extends into the closing installation hole. When the closing punch moves upward to exit the closing installation hole, the limiting flange interferes with the upper pressure ring to prevent the closing punch from exiting the closing installation hole.
[0016] Furthermore, the closing component and the riveting component approach each other when performing the riveting and closing action, and move away from each other after the action is completed; the two are brought close and away from each other through a guide structure, and the guide structure can adopt a variety of schemes, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the guide structure includes a number of guide columns arranged on the workbench, and the closing component is provided with guide holes corresponding to the guide columns one by one, and the guide columns are also provided with reset elastic parts. When the closing component is pressed down, it moves along the guide columns and compresses the reset elastic parts, and after the pressing action is completed, it returns to the initial position under the elastic force of the reset elastic parts. When the above scheme is adopted, the guide holes can be set on the lifting plate, and after the guide holes cooperate with the guide columns, the lifting plate is lifted and lowered along the guide columns to realize the riveting and closing actions.
[0017] Furthermore, in order to improve the stability of the assembly process, it is necessary to fix the panel of the assembly locking pin assembly, which can be achieved through a variety of solutions. Here, one feasible option is proposed: the workbench is also provided with a positioning assembly, and the workbench is provided with an anti-slip groove; the positioning assembly includes a locking block that is arranged in the anti-slip groove and reciprocates along it, and the locking block cooperates with the stopper through a tightening screw. The stopper is located at the notch of the anti-slip groove. When the tightening screw is rotated, the locking block and the stopper are pulled close and clamp the anti-slip groove. When the above scheme is adopted, the anti-slip groove can adopt an inverted T-shaped groove, an inverted wedge-shaped groove and other structures, and a T-shaped limiting structure or an inclined limiting surface is correspondingly provided on the locking block. The tightening screw cooperates with the locking block and the stopper through a thread. When the tightening screw is rotated, the locking block and the stopper are close to each other, so as to be fastened to the anti-slip groove.
[0018] Furthermore, the layout of the anti-slip groove is not limited to a single one: the anti-slip groove includes an X-direction groove and a Y-direction groove, and positioning components are provided on the X-direction groove and the Y-direction groove to fix the panel to be assembled with the locking pin component in the X and Y directions.
[0019] The above content discloses an assembly tool for a spring locking pin assembly, and the present invention also discloses an assembly method for the spring locking pin.
[0020] A method for assembling a spring lock nail assembly, using the above-mentioned assembly tool, comprises:
[0021] Place the panel to be assembled with the locking assembly on the workbench, make the support fit the panel, and align the riveting holes of the support with the assembly holes on the panel;
[0022] Assemble the sleeve to be riveted and closed into the assembly hole, and then assemble the locking pin and spring part into the sleeve;
[0023] Press down the closing punch to make it contact and push the sleeve downward, the lower end of the sleeve is pressed by the riveting head to realize the riveting action, and the upper end of the sleeve is pressed by the closing protrusion to realize the closing action;
[0024] The closing punch is unloaded and reset to complete the riveting and closing of the spring lock pin assembly on the panel.
[0025] Compared with the prior art, some beneficial effects of the technical solution disclosed in the present invention include:
[0026] The present invention can synchronously perform riveting and closing on the locking nail assembly on a workbench by adjusting the matching mode of the riveting assembly and the closing assembly, and completes two operations by one device, thereby saving equipment, reducing construction procedures, and improving the assembly efficiency of the locking nail assembly.
