Description
Technical Field
[0001] This utility model patent relates to the technical field of assembly fixtures, and more specifically, to a coaxial frame assembly fixture. Background Technology
[0002] A door lock is a device used to lock a door and prevent others from opening it. The door lock achieves locking and unlocking through various internal parts. The door lock includes a lock frame and metal plates on both sides. In production, in order to facilitate the assembly and transportation of parts, the metal plates need to be assembled on both sides of the lock frame before leaving the factory.
[0003] Currently, metal sheets and lock frames are assembled using screws, which are generally locked manually, a time-consuming, labor-intensive, and inefficient process.
[0004] To improve assembly efficiency, jigs are used to assist assembly. For example, the prior patent with authorization announcement number CN208215193U discloses a jig for fixing a lock body transmission plate, including a seat for placing the lock body transmission plate and a screwing rod. The seat has a downwardly recessed placement groove, and the placement groove has a moving block that is controlled to reciprocate by the screwing rod. The depth of the placement groove is the same as the height of the moving block. The seat has multiple first fixing grooves, and the moving block has multiple second fixing grooves. When the first fixing grooves and the second fixing grooves move towards each other, they can clamp and fix the screw assembly. When the screw assembly is in a fixed state, the lock body transmission plate is placed above the screw assembly, and the screw passes through the lock body transmission plate from top to bottom and is connected with the screw assembly.
[0005] In the existing technology, there is a lack of positioning for the thin sheet. During assembly, it is difficult to ensure that the metal sheets on both sides are coaxial with the central hole of the lock frame, which can easily cause assembly misalignment. Furthermore, the metal sheets are prone to deformation, resulting in a poor assembly qualification rate of the metal sheets and the lock frame. Utility Model Content
[0006] The purpose of this utility model is to provide a coaxial frame assembly fixture, which aims to solve the problem that metal sheets and lock frames are not easy to assemble coaxially in the prior art.

[0025] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.
[0026] A coaxial frame assembly fixture includes a fixture base 1 and a plate fixing shaft 2. The fixture base 1 has a frame fixing groove 11 and two plate fixing grooves 12. The frame fixing groove 11 is recessed downward and used to place the locking frame 3. The two plate fixing grooves 12 are arranged correspondingly on both sides and are connected to the frame fixing groove 11. The upper part of the plate fixing groove 12 forms an upper fixing surface, which extends vertically. The lower part of the plate fixing groove 12 forms a lower fixing surface. The upper fixing surface and the lower fixing surface are used to lay and abut against the metal plate 4. The plate fixing shaft 2 passes through the two metal plates 4 and the two lower fixing surfaces simultaneously. The plate fixing shaft 2 is used to position the metal plate 4.
[0027] In the aforementioned coaxial frame assembly fixture, during assembly, the locking frame 3 is first loaded into the frame fixing slot 11, then the two metal plates 4 are loaded into the plate fixing slot 12, and then the fixing shaft 2 passes through the two metal plates 4 and the fixture seat 1. At this time, the metal plates 4 and the locking frame 3 are arranged in an overlapping manner. Finally, the locking frame 3 and the two metal plates 4 are locked together by screws. In this way, under the positioning action of the fixture seat 1 and the fixing shaft 2, the offset of the metal plates 4 and the locking frame 3 is restricted. At the same time, the central holes of the metal plates 4 and the locking frame 3 are arranged coaxially, which facilitates the locking of screws. Furthermore, it improves the assembly accuracy, reduces the risk of uneven stress and deformation of the metal plates 4, and improves the product assembly qualification rate.
[0028] The metal sheet 4 has a fixing hole, which is coaxial with the central hole of the lock frame 3, which facilitates the fastening of screws and improves assembly accuracy.
[0029] The metal sheet 4 has multiple fixing holes, and the locking frame 3 has multiple central holes. Each fixing hole and each central hole of the locking frame 3 are arranged coaxially, which facilitates the fastening of screws and improves assembly accuracy.
[0030] The fixture base 1 includes a mounting platform, which is located in the mounting groove 11. The mounting platform has two platform protrusions 13, which are arranged at intervals and are protruding. The lock frame 3 has a lock seat block, and the two platform protrusions 13 are used to abut and position the lock seat block.
[0031] In this way, the two protruding strips 13 can position and limit the offset of the locking frame 3, improve the stability of the locking frame 3 during loading, and thus improve the accuracy of subsequent assembly.
[0032] Furthermore, the raised strip 13 has a top surface, which is horizontally arranged, and the top surfaces of the two raised strips 13 are arranged flush. The top surface is used to flatly support the lock frame 3, thereby improving the stability of the lock frame 3 and thus improving the accuracy of subsequent assembly.
[0033] The raised strip 13 has a raised strip surface, which is arranged vertically and is aligned with and flush with the upper fixed surface. The raised strip surface and the upper fixed surface are laid flat and in contact with the metal sheet 4. This improves the positioning range of the metal sheet 4, enhances the stability and accuracy of the metal sheet 4 feeding, and thus improves the accuracy of subsequent assembly.
[0034] The fixture base 1 includes a front frame block 14 and a rear frame block 15, with a mounting groove 11 formed between the front frame block 14 and the rear frame block 15. The front frame block 14 has a front frame surface, which is simultaneously arranged in contact with the ends of the lock frame 3 and the metal piece 4. In this way, the front frame block 14 and the rear frame block 15 work together to position and restrict both ends of the lock frame 3, improving the loading accuracy of the lock frame 3. At the same time, since the front frame surface is simultaneously arranged in contact with the ends of the lock frame 3 and the metal piece 4, the front frame surface is aligned with the lock frame 3 and the metal piece 4, improving the loading accuracy of the lock frame 3 and the metal piece 4, thereby improving the accuracy of subsequent assembly.
[0035] The fixture base 1 includes a tail fixing block 16, and a plate fixing groove 12 is formed between the front frame block 14 and the tail fixing block 16. The tail fixing block 16 has a tail fixing surface, and the front frame surface and the tail fixing surface are respectively arranged in abutment with the two ends of the metal plate 4. In this way, under the cooperation of the front frame surface and the tail fixing surface, the two ends of the metal plate 4 are restricted and positioned to prevent the metal plate 4 from shifting, ensure the alignment of the metal plate 4 with the lock frame 3, and improve the assembly stability of the metal plate 4 and the lock frame 3.
[0036] The rear frame block 15 has a frame side, an upper fixed surface, a frame side and a lower fixed surface arranged in an integral and mating manner, and the upper fixed surface, the frame side and the lower fixed surface are simultaneously arranged to lay flat and abut against the metal sheet 4; in this way, the stability and accuracy of the metal sheet 4 are improved, and the alignment of the metal sheet 4 with the lock frame 3 is facilitated, thereby improving the assembly stability of the metal sheet 4 and the lock frame 3.
[0037] The coaxial frame assembly fixture includes a fixed plate block 5, which is assembled or separated from the fixture base 1. The fixed plate block 5 has a fixed plate groove that extends through the bottom. The fixed plate groove is used for the rear frame block 15 and two metal plates 4 to be embedded. The fixed plate groove has two fixed plate walls, which are arranged to lay flat against the two metal plates 4 respectively, and the two fixed plate walls respectively position the two metal plates 4.
[0038] Before the locking operation, the fixing block 5 and the fixture seat 1 are assembled vertically. The two fixing blocks are used to position the two metal pieces 4, which improves the feeding effect of the metal pieces 4 and ensures the alignment effect between the metal pieces 4 and the locking frame 3.
[0039] The fixture 1 has a connecting slot hole, with both ends of the connecting slot hole passing through the lower fixed surface. The connecting slot hole is used for the fixed plate shaft 2 to pass through. The metal plate 4 has a circular plate part with a circular hole groove. The diameter of the circular hole groove is arranged in the same manner as the diameter of the connecting slot hole. The fixed plate shaft 2 passes through the circular hole groove and the connecting slot hole simultaneously.
[0040] This facilitates the through-layout of the fixed plate shaft 2, thereby limiting the offset of the metal plate 4, improving the alignment between the metal plate 4 and the locking frame 3, and thus improving the accuracy of subsequent assembly.
[0041] The depth of the plate fixing groove 12 is arranged in the same manner as the thickness of the metal sheet 4, thereby improving the positioning effect of the plate fixing groove 12 on the metal sheet 4.
[0042] The coaxial frame assembly fixture includes a detection plate, which is arranged in a flat shape and is used to overlap and abut against the side of the fixture seat 1 and the metal sheet 4. Before locking, the loading effect of the metal sheet 4 can be detected by overlapping the side of the fixture seat 1 and the metal sheet 4 with the detection plate, thereby detecting whether the metal sheet 4 is deformed. After locking, the metal sheet 4 is again overlapped with the side of the fixture seat 1 and the metal sheet 4 with the detection plate to detect whether the metal sheet 4 is deformed after locking and assembly, so as to ensure the assembly qualification rate of the product.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
