[0001] The utility model relates to the technical field of processing positioning, in particular to a positioning support device used for processing single-leg channel steel of a forklift door frame. Background Art

[0002] The forklift mast is the main load-bearing structure of the forklift picking device and the mechanism for lifting goods, also known as the gantry. It consists of an inner mast, an outer mast, a fork frame, forks, sprockets, chains, lifting cylinders and tilting cylinders. Depending on the lifting height requirements of the forked goods, the forklift mast can be made into two or more levels. Common ordinary forklifts mostly use a two-stage mast.

[0003] However, in the prior art, the main component of the existing forklift mast itself is channel steel, among which the single-leg channel steel used for assembling the forklift mast is a type of channel steel. A major feature of the single-leg channel steel is that there is a protrusion on the bottom plane. When the groove surface of the single-leg channel steel needs to be deburred, it cannot be placed stably due to the protrusion on the bottom, resulting in that it is difficult for a general positioning support device to ensure the stability of the single-leg channel steel itself during processing, thereby affecting the final processing quality. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: when the groove surface of the single-leg channel steel needs to be deburred, due to the protrusion at the bottom, it cannot be placed stably, resulting in that the general positioning support device is difficult to ensure the stability of the single-leg channel steel itself during processing, thus affecting the final processing quality.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a positioning and supporting device for processing single-leg channel steel of forklift door frame, comprising a workbench, wherein four corners of the workbench are embedded and fixed with a No. 1 electric telescopic rod, and one end of the No. 1 electric telescopic rod is fixedly connected to a connecting block, the upper surface of the connecting block is fixedly connected to a fixing rod, an extension plate is slidably connected to the fixing rod, and a supporting splint is fixedly connected to one side surface of the extension plate, the upper surface of the supporting splint is slidably connected to an extrusion positioning plate, and a screw rod is rotatably connected and penetrated at the slide rail of the supporting splint, the screw rod is threadedly connected to the extrusion positioning plate, a slider is slidably connected at the lower surface of the supporting splint, and a No. 2 electric telescopic rod is fixedly connected to the lower end of the slider, the No. 2 electric telescopic rod is penetrated and fixedly connected to the workbench, and a single-leg channel steel body is placed on one side of the supporting splint and the extrusion positioning plate on the upper surface of the workbench.

[0006] As a preferred implementation, a rubber anti-slip pad is fixedly connected to the extrusion surface of the extrusion positioning plate.

[0007] As a preferred implementation, one end of the screw rod is fixedly connected to a rotating wheel.

[0008] As a preferred embodiment, a retractable platform is fixedly connected to the bottom of the second electric telescopic rod.

[0009] As a preferred implementation, a partition plate is fixedly connected to the upper surface of the storage platform.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model, with the help of the No. 2 electric telescopic rod, changes the placement height of the support splint on the workbench to achieve a height that adapts to the protrusion at the bottom of the single-leg channel steel body, so that the support splint can then stably support the single-leg channel steel body. With the help of the No. 1 electric telescopic rod and the screw rod, the support splint and the extrusion positioning plate are driven to move horizontally, so that the support splint and the extrusion positioning plate respectively squeeze and fix different parts of the single-leg channel steel body, thereby improving its stability after stably placing.
