Technical Field

[0001] The utility model relates to the technical field of combined processing equipment, in particular to an assembling device for a lock core decorative cover. Background Art

[0002] The car door lock cylinder is an important component for opening and closing car doors. It includes sub-components such as the core sleeve and lock shell. Since some lock cylinders are made of plastic, metal decorative covers need to be installed for beauty. The decorative cover also has the function of protecting the lock cylinder.

[0003] The existing assembly technology is to use pliers to embed the decorative cover into the lock core by hand. This method is extremely inefficient and cannot guarantee assembly accuracy.

[0004] The prior art discloses a patent with announcement number CN209021953U, which includes a rotating seat, a support seat, and a tooling assembly arranged on the support seat. The support seat is arranged on the rotating seat, and the tooling assembly includes a frame. The frame is provided with a clamping and positioning groove seat, a first cylinder and a second cylinder. The first cylinder is a clamping and positioning cylinder, and the second cylinder is a detection cylinder. A sensor assembly is also installed on the frame. Two sets of cylinder actions are added. The first cylinder is a clamping and positioning cylinder. After the product is in place, the sensing signal of the sensor assembly is transmitted to the induction switch through the communication bus. The induction switch starts the first cylinder to clamp and position the product. The second cylinder is a detection cylinder. The second cylinder piston rod is in action to detect whether the rivets on the clamping and positioning groove seat have been riveted.

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

[0006] During the assembly of the existing lock core and lock core cover, due to the different clamping forces of the operator's handheld pliers, the lock core cover and the lock core are easily deflected, which affects the stability of the assembly.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] In response to the defects in the existing technology, the utility model provides a lock core decorative cover assembly device to solve the problem in traditional technology that during the assembly process of the lock core and the lock core cover, the lock core cover is easily skewed due to the different clamping force of the operator's handheld pliers, thereby affecting the stability of the assembly.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] The lock cylinder decorative cover assembly device includes a support platform, a fixed seat is fixed on the support platform, a support seat and a sliding seat are horizontally slidably provided on one side of the fixed seat, a positioning groove is provided on the upper end of the support seat, and an avoidance hole is horizontally provided on the opposite side wall of the positioning groove, and the side walls of the fixed seat and the sliding seat facing the support seat are respectively fixed with assembly pins, and the two assembly pins are correspondingly slidably arranged in the avoidance holes.

[0011] In a non-use state, the two assembly pins are hidden in the avoidance holes; in a use state, the two assembly pins extend into the positioning grooves.

[0012] As an optimized solution, a cylinder is horizontally fixed on the support platform, and the telescopic end of the cylinder is fixed to the sliding seat.

[0013] As an optimized solution, two horizontally arranged guide pillars are fixedly connected in parallel along the horizontal direction on the fixing seat, and guide holes matching the guide pillars are respectively opened on the supporting seat and the sliding seat.

[0014] As an optimized solution, a first rectangular sliding groove is provided in the guide hole on the support seat along its sliding direction, and a first sliding block constrained in the first rectangular sliding groove is fixedly connected to the guide column.

[0015] As an optimized solution, a second rectangular sliding groove is provided in the guide hole on the sliding seat along its sliding direction, and a second sliding block constrained in the second rectangular sliding groove is fixedly connected to the guide column.

[0016] As an optimized solution, two horizontally arranged first compression springs are vertically arranged in parallel between the fixing seat and the supporting seat, and two ends of the first compression springs are respectively against the fixing seat and the supporting seat.

[0017] As an optimized solution, first abutment grooves are respectively formed on opposite end walls of the fixing seat and the supporting seat, and both ends of the first compression spring are respectively constrained in the first abutment grooves.

[0018] As an optimized solution, two horizontally arranged second compression springs are vertically arranged in parallel between the sliding seat and the supporting seat, and two ends of the second compression springs are respectively against the sliding seat and the supporting seat.

[0019] As an optimized solution, second abutment grooves are respectively formed on the opposite end walls of the sliding seat and the supporting seat, and both ends of the second compression spring are respectively constrained in the second abutment grooves.

[0020] As an optimized solution, a push switch connected to the cylinder is further provided on the support platform.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] Before assembling the lock cylinder and the metal decorative cover, first put the metal decorative cover on the end of the lock cylinder, then buckle the lock cylinder upside down in the positioning groove of the support seat, and then press the switch. The cylinder pushes the sliding seat and the support seat toward the fixed seat. When the sliding seat and the fixed seat are respectively in contact with the support seat, the movement ends. At this time, the assembly pin extends from the avoidance hole and extends into the positioning groove. The assembly pin extends and abuts against the upper edge of the metal decorative cover. Since the upper end of the lock cylinder is provided with a limiting groove, the assembly pin will embed the upper edge of the metal decorative cover into the limiting groove, thereby realizing the rapid combination of the metal decorative cover and the lock cylinder, thereby ensuring the assembly efficiency and assembly accuracy between the metal decorative cover and the lock cylinder.

[0023] After the metal decorative cover and the lock core are assembled, the telescopic cylinder is cut off, and the support seat and the sliding seat are retracted under the action of the first compression spring and the second compression spring, and the retraction stroke of the support seat and the sliding seat is limited by the rectangular slide groove and the slider.
