[0016] Preferably, the sliding corner has a right-angle structure, and its top wall abuts against the sieve plate to form a fixed support surface.

[0017] (III) Beneficial Effects

[0018] This utility model embodiment provides a quick positioning and clamping mechanism for welding the sieve box of a sorting machine. It has the following beneficial effects:

[0019] 1. By cooperating with the upper and lower fixed components, the screen plate and the wedge block are held against the inner wall of the sliding corner, thereby realizing the rapid adjustment of the horizontal position of the screen plate. This replaces the traditional guide rail, slider and connecting rod module, significantly reducing the number of moving parts and reducing the difficulty of assembly and debugging.

[0020] 2. By vertically distributing the upper and lower fixed components at the corner of the desktop and adapting the guide groove and sliding angle, the translation component is integrated inside the workbench, avoiding the need to arrange large guide rails along the edge of the screen, significantly reducing the overall size of the equipment and saving production space.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1-4 A quick positioning and clamping mechanism for welding the sieve box of a cleaning machine. The cleaning machine, also called a powder cleaning machine or a screening machine, is used to remove impurities from grains. It includes a tabletop 1, and a lower fixing part 2 and an upper fixing part 3 set at the corner of the tabletop 1. The upper fixing part 3 and the lower fixing part 2 are distributed vertically at the upper and lower positions of the tabletop 1, and a groove for the upper fixing part 3 to move is also provided at the corner of the tabletop 1.

[0028] The lower fixing member 2 includes a platform 21, a slide 22, and a slide screw 23. The slide 22 is disposed on the upper part of the platform 21 and slides on it. The platform 21 extends upward and is connected to the bottom of the tabletop 1. The slide screw 23 is also threaded on the platform 21. One end of the slide screw 23 is connected to the slide 22 through a bearing, and the other end is connected to a handle for easy rotation. When the slide screw 23 is driven to rotate, the slide screw 23 is threadedly engaged with the platform 21, which can push the slide 22 on the platform 21 and slide along the axial direction of the slide screw 23, thereby driving the upper fixing member 3 on the upper part of the tabletop 1 to slide.

[0029] The upper fixing member 3 includes a sliding corner 31 with a right angle structure. An extension plate 32 is connected to the right angle side of the sliding corner 31, and the extension plate 32 extends upward to form a vertical plate. A push column 33 is slidably arranged on the extension plate 32. The push column 33 is connected to the push column screw 35 through a bearing. The push column screw 35 is threadedly connected to the vertical plate. That is, rotating the push column screw 35 can drive the push column 33 to slide along the extension plate 32.

[0030] A wedge 34 is connected to the right-angle side of the push column 33 near the sliding angle 31. A wedge groove 37 is provided on the sliding angle 31 opposite to the wedge 34 for the wedge 34 to enter. When the wedge 34 slides into the wedge groove 37, the screen plate can be lifted from the bottom until it abuts against the top wall of the sliding angle 31 to form a fixed position.

[0031] In order to limit the movement direction of the push column 33, a strip groove 36 is provided on the extension plate 32, and the vertically arranged limiting rod on the push column 33 is adapted to the strip groove 36.
