Description

Technical Field

[0001] The utility model relates to the processing of printer parts, in particular to the processing of the bottom bracket of a large printer. Background Art

[0002] For the bottom bracket of a large printer, plastic support blocks need to be installed at the bottom. The plastic support blocks are fixed to the bottom of the bottom bracket by screws. During installation, the bottom bracket needs to be fixed on the working platform. Workers place the plastic support blocks at the corresponding installation positions, and then use screws to fix the plastic support blocks to the bottom bracket. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a positioning jig for the bottom bracket of a large printer, which facilitates workers to install plastic support blocks on the bottom bracket.

[0004] To solve the above technical problem, the utility model provides the following technical solution: A positioning jig for the bottom bracket of a printer, including positioning columns, lifting seats and a pressing block mechanism installed on the working platform. Two lifting seats are located on the left and right sides of several positioning columns, and the pressing block mechanism is located beside the lifting seats. The upper surface of the lifting seat is a positioning surface, and positioning blocks are arranged on the positioning surface. After the lifting seat rises, the height of the positioning surface is lower than that of the positioning columns. After the lifting seat descends, the pressing block of the pressing block mechanism extends horizontally and can press against the top of the product on the lifting seat.

[0005] Workers stand in front of the working platform and place the bottom bracket of the large printer on the lifting seat at the highest position. The left and right sides of the bottom bracket of the large printer are supported on the positioning surfaces of the lifting seats and are positioned by the positioning blocks. Moreover, the hole positions of the bottom bracket of the large printer cooperate with the positioning columns. Then, the lifting seat descends, and the bottom bracket of the large printer also descends accordingly. When the bottom bracket of the large printer reaches the lowest position, the pressing block of the pressing block mechanism extends horizontally and presses against the top of the bottom bracket of the large printer. In this way, the bottom bracket of the large printer is fixed on the working platform. Workers place the plastic support blocks at the corresponding installation positions, screw the screws, and fix the plastic support blocks to the bottom bracket of the large printer.

[0006] Since the bottom bracket of the large printer has a certain height, when placing the bottom bracket of the large printer, the lifting seat is raised to the highest position, which is convenient for workers to position the bottom bracket of the large printer on the lifting seat and the positioning columns. After positioning, the bottom bracket of the large printer is lowered, which is convenient for workers to install the plastic support blocks on the top surface of the bottom bracket of the large printer.

[0007] The briquetting mechanism includes a vertical plate fixed on the working platform, a horizontal plate fixed on the vertical plate, a horizontal cylinder installed on the horizontal plate, a sliding seat movably matched with the horizontal plate, and a pressing plate installed on the sliding seat. The briquetting block is installed at the front end of the pressing plate, and the piston rod of the horizontal cylinder is connected to the sliding seat. Driven by the horizontal cylinder, the sliding seat moves horizontally, driving the pressing plate and the briquetting block to move horizontally, and the briquetting block presses on the top surface of the bottom bracket of the large printer. The pressing plate is fixed on the top of the sliding seat by the first bolt.

[0008] A guiding block is provided on one side of the horizontal plate, and a sliding groove is provided on one side of the sliding seat. The sliding groove is movably matched with the guiding block. The sliding groove and the guiding block guide the horizontal displacement of the sliding seat.

[0009] The horizontal cylinder is connected to the horizontal plate through a frame-shaped connecting piece. The frame-shaped connecting piece includes a frame-shaped structure and a connecting structure. The horizontal cylinder is fixed in the frame-shaped structure, and the connecting structure is connected to the horizontal plate. A second bolt is installed on the frame-shaped structure, and the second bolt fixes the horizontal cylinder in the frame-shaped structure. The connecting structure is fixedly connected to the horizontal plate through a third bolt.

[0010] An L-shaped limiting block is provided on the vertical plate. A guiding groove is provided between the L-shaped limiting block and the vertical plate. One side of the pressing plate is movably matched in the guiding groove. The briquetting block is installed on the other side of the pressing plate, and the head end of the briquetting block is provided with an inclined surface. Under the guidance of the guiding groove, the pressing plate moves horizontally, and the briquetting block moves accordingly. The inclined surface of the briquetting block contacts the edge of the bottom bracket of the large printer and presses down the bottom bracket of the large printer. After the inclined surface of the briquetting block crosses the edge of the bottom bracket of the large printer, the briquetting block presses tightly on the bottom bracket of the large printer. The L-shaped limiting block has a limiting effect on the pressing plate to prevent the end of the pressing plate with the briquetting block from tilting up. The L-shaped limiting block is fixed on the vertical plate by the fourth bolt.

[0011] Two briquetting mechanisms are provided beside each lifting seat. One briquetting mechanism is located on the front side of the lifting seat, and the other briquetting mechanism is located on the rear side of the lifting seat. In this way, the four briquetting mechanisms act on the four corners of the bottom bracket of the large printer, and the bottom bracket of the large printer is stably fixed.

Two lifting seats are located on the left and right sides of several positioning posts, and the pressing block mechanism is located beside the lifting seats. The upper surface of the lifting seat is a positioning surface 31, on which a positioning block 32 is provided. After the lifting seat rises, the height of the positioning surface is lower than that of the positioning posts. After the lifting seat descends, the pressing block 41 of the pressing block mechanism extends horizontally and can press against the top of the product on the lifting seat.

[0031] The worker 50 stands in front of the working platform 10 and places the bottom bracket 60 of the large printer on the lifting seat 30 at the highest position. The left and right sides of the bottom bracket of the large printer are supported on the positioning surface 31 of the lifting seat and are positioned by the positioning block 32. Moreover, the hole positions of the bottom bracket 60 of the large printer cooperate with the positioning posts 20. Then, the lifting seat 30 descends, and the bottom bracket of the large printer also descends accordingly. When the bottom bracket 60 of the large printer reaches the lowest position, the pressing block 41 of the pressing block mechanism 40 extends horizontally and presses against the top of the bottom bracket of the large printer. In this way, the bottom bracket 60 of the large printer is fixed on the working platform 10, and the worker places the plastic support block at the corresponding installation position and screws it to fix the plastic support block on the bottom bracket 60 of the large printer.
