Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, specifically to a positioning fixture for steel grating processing. Background Technology

[0002] Steel grating, also known as steel grid plate or grating, is an open-type steel structure made of load-bearing flat steel and crossbars orthogonally combined at a certain interval and fixed by welding or press-locking.

[0003] In the existing technology, steel grating positioning fixtures mostly adopt fixed frame structures, which have limited size adjustment range. When processing steel gratings of different lengths, the entire positioning frame needs to be replaced, which is not only cumbersome to operate, but also increases equipment investment costs. Therefore, a positioning fixture for steel grating processing is needed. Summary of the Invention

[0004] The purpose of this utility model is to provide a positioning fixture for processing steel grating, which solves the problems mentioned in the background art.

[0005] This application provides a positioning fixture for processing steel grating, including a positioning table. A fixed frame is fixedly connected to the top of the positioning table. A movable frame is symmetrically slidably provided on the side of the top of the positioning table away from the fixed frame. Fixed blocks are fixedly connected to the outer walls of both the movable frame and the fixed frame. A guide rod is provided through the fixed block. A locking nut is screwed to the outer wall of the guide rod. A limiting rod is provided through the front wall of both the movable frame and the fixed frame. A locking screw is threaded through the top of both the movable frame and the fixed frame, and the locking screw abuts against the limiting rod.

[0006] In use, first place the steel grating into the fixed frame, making it abut against the inner wall of the fixed frame. Then slide the movable frame until it abuts against the end of the steel grating furthest from the fixed frame. By adjusting the distance between the movable and fixed frames, it can accommodate steel gratings of different widths. Furthermore, with the cooperation of the fixed block and guide rod, the movable frame can always slide symmetrically with the fixed frame. Then, the movable and fixed frames can be locked in place using the locking nut. Next, slide the limiting rod on one outer wall of the movable and fixed frames until it abuts against the outer wall of the steel grating. Finally, lock the limiting rod in place using the locking screw. The opening width of the movable and fixed frames can be adjusted to accommodate steel gratings of different widths. Through the cooperation of these structures, steel gratings of different widths and lengths can be positioned, making operation simple.

[0007] Optionally, both the movable frame and the fixed frame are U-shaped structures, and the openings of the movable frame and the fixed frame are arranged opposite to each other.

[0008] By adopting the above technical solution, the steel grating can be clamped and fixed by the movable frame and the fixed frame with opposite openings.

[0009] Optionally, the outer wall of the end of the limiting rod facing the steel grating is provided with anti-slip texture.

[0010] By adopting the above technical solution, the anti-slip texture can increase the friction between the limiting rod and the steel grating, thereby improving the fixing effect of the steel grating.

[0011] Optionally, the guide rod is made of stainless steel.

[0012] By adopting the above technical solutions, it is beneficial to improve the corrosion resistance and toughness of the guide rod and extend its service life.

[0013] Optionally, the outer wall of the guide rod is provided with an external thread that matches the locking nut.

[0014] By adopting the above technical solution, it is beneficial to lock and position the nut.

[0015] Optionally, support columns are fixedly connected to the four corners of the bottom of the positioning platform.

[0016] By adopting the above technical solution, it is beneficial to provide stable support for the positioning platform.

[0017] Optionally, both the movable frame and the fixed frame are provided with slots that are adapted to the limiting rod.

[0018] By adopting the above technical solution, it is beneficial for the limiting rod to slide on the movable frame and the fixed frame, and the opening width of the movable frame and the fixed frame can be adjusted.

[0019] Optionally, two guide rods are provided, and the two guide rods are arranged symmetrically on the left and right.

[0020] By adopting the above technical solution, it is beneficial for the movable frame and the fixed frame to always be in the same straight line, thereby improving the positioning effect of the steel grating.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: This technical solution utilizes a sliding movable frame to adjust the distance between the movable frame and the fixed frame, making it suitable for steel gratings of different widths. With the aid of a fixed block and guide rod, the movable frame slides symmetrically with the fixed frame. A locking nut secures the movable and fixed frames. A sliding limit rod on the movable and fixed frames allows for adjustment of the opening width. After adjustment, the limit rod is locked in place using a locking screw. Through the coordination of these structures, steel gratings of different lengths and widths can be positioned, making operation simple. Attached Figure Description
