[0001] The utility model relates to the technical field of combined processing equipment, in particular to an adjustable assembly device for a core sleeve and a lock shell. Background Art

[0002] The car door lock core is an important component for opening and closing car doors. It includes sub-components such as the core sleeve and the lock shell. During the assembly process of the core sleeve and the lock shell, due to the structural relationship of the assembly position, a large force is required to assemble the core sleeve to the lock shell. The core sleeve itself has a force release characteristic. After the core sleeve is assembled to the lock shell, external force is required to limit the core sleeve to prevent the core sleeve from popping out of the lock shell assembly position and causing the assembly operation to fail, which brings difficulty to the assembly operation.

[0003] The existing assembly technology is to hammer the core sleeve with a hammer by hand and embed the core sleeve into the lock shell. This method is extremely inefficient and cannot guarantee assembly accuracy.

[0004] Prior art discloses a patent with publication number CN215469410U, titled "A Device for Facilitating the Assembly of an Automobile Door Lock Cylinder," comprising a base, a slider, a pressure plate, a connecting post, and a mounting arm. This device allows for quick and stable assembly of the door lock cylinder spring and connecting rod onto the lock cylinder body, ensuring product quality, saving time and effort, and increasing assembly efficiency, facilitating assembly operations and improving labor productivity.

[0005] The existing technologies including the above patents have gradually exposed their shortcomings as they are used, mainly in the following aspects:

[0006] First, during the assembly process of the core sleeve and the lock shell, when the cylinder presses down the core sleeve and the lock shell, the stroke is prone to over-position or under-stroke, resulting in the inability to stably assemble the core sleeve and the lock shell, affecting the stability of the assembly.

[0007] Second, since the volumes of core sleeves and lock shells of different models are different, multiple assembly tools need to be set up to match the core sleeves and lock shells of different models, which not only occupies a large space but also increases the manufacturing cost.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0009] In response to the defects in the existing technology, the utility model provides an adjustable assembly device for the core sleeve and lock shell, which is used to solve the problem that in the traditional technology, during the assembly process of the core sleeve and the lock shell, the cylinder is prone to over-stroke or under-stroke when pressing down the core sleeve and the lock shell, resulting in the inability to stably assemble the core sleeve and the lock shell, affecting the assembly stability.

[0010] To achieve the above objectives, the present invention provides the following technical solutions:

[0015] As an optimized solution, a square positioning block is fixedly connected to the lower surface of the base, and a square positioning groove matching the square positioning block is provided on the base.

[0016] As an optimized solution, the positioning assembly includes pressure plates respectively located on both sides of the assembly seat, the pressure plates are arranged to slide vertically, and one end of the pressure plate is against the upper surface of the boss.

[0017] As an optimized solution, a mounting hole is opened horizontally on the upper edge of the pressure plate, a fixing bolt is inserted into the mounting hole, the lower end of the fixing bolt is threadedly connected to the base, and the handle end of the fixing bolt is against the upper surface of the pressure plate.

[0018] As an optimized solution, a stud is vertically fixed on the base, a screw sleeve is threadedly connected to the stud, and a positioning column inserted into the screw sleeve is fixed on the bottom surface of the other end of the pressure plate.
