AI Technical Summary
The accuracy deviation of traditional steel plate laying platforms is too large and the clamping position is limited. The clamping tooling cannot be effectively used for the repair of the group, resulting in the deviation of the equipment parts group, which is long and has high cost.
A group-to-pair platform was designed, including rails, 14# channel steel, steel plates and concrete. The integrated frame was formed by welding and concrete was poured on it to ensure the high accuracy and stability of the platform.
It significantly reduces manual investment such as grinding, clamping and alignment, improves the qualification rate of finished products, and achieves that the cost is lower than that of the T-trough platform and the set accuracy is higher than that of the traditional steel plate platform.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of equipment structural parts manufacturing and repair, and in particular provides an assembly platform. It is applied to the assembly and repair of equipment structural parts. The traditional steel plate laying platform has too large precision deviation, the clamping position is limited, and the assembly and repair cannot use the clamping tooling well, resulting in too large deviation of equipment parts assembly. Background Art
[0002] Compared with steel structures, the manufacturing and repair of equipment structural parts have higher precision, and most of them are assembly parts including transmission linkage, tolerance matching connectors, etc., which require high platform precision. Traditional platforms are mainly divided into two categories: steel plate self-made platforms and T-slot platforms.
[0003] Traditional steel plate platform: In the past, the traditional steel plate platform we used would cause deformation of the platform due to heat and other reasons after long-term use, and the accuracy could not be guaranteed. The assembly using the traditional platform required the workpiece to be aligned again before completion, which greatly wasted construction time.
[0004] During the assembly and repair process, beam clamping tools such as wedges and knife handles will be used. Traditional steel plate platforms can only be fixed by welding. After the spare parts construction is completed, the platform needs to be re-polished until there are no protruding spots on the surface before the next spare parts construction can be carried out.
[0005] T-slot platform: T-slot platform, also called T-slot plate, is a cast iron plate with T-slots on the surface. It is a cast iron platform measuring tool used for assembling and debugging mechanical equipment. It is cast with high-strength cast iron, which is not only accurate and stable, but also strong and durable.
[0006] The working surface adopts the scraping process and is inspected by coloring to ensure the accuracy of the plane. The working surface generally has T-slots, and long holes and round holes can also be processed according to requirements. This platform is made of high-quality pure iron casting. It is widely used in the assembly, debugging, welding and riveting of power machinery and equipment. This product has a T-slot on the surface to fix the machinery and equipment.
[0007] This type of platform is relatively expensive and is only suitable for the assembly and production of high-precision workpieces. It is not practical for the production and repair of equipment structural parts. Utility Model Content
[0008] The purpose of the utility model is to provide an assembly platform, which overcomes the problems of large precision deviation of traditional steel plate laying platforms, limited clamping position, and inability to use clamping tools well during assembly and repair, resulting in large deviation of equipment assembly; long construction time and high cost.
[0009] The utility model comprises a steel rail (1), a 14# channel steel (2), a steel plate (3), and concrete (4); the 14# channel steel (2) and the steel plate (3) are welded to form an integral frame, that is, the steel plate (3) is located on the side of the 14# channel steel (2) and serves as a rib plate and a connecting piece; the 6M steel rail (1) is welded on the frame formed by the 14# channel steel (2) and the steel plate (3); and the concrete (4) is located 20 mm below the upper surface of the 6M steel rail (1).
[0010] The steel rail 1 is a 43 kg / m steel rail, and the steel plate 3 is 20 mm thick.
[0011] The production steps of this utility model are as follows:
[0012] The upper surface of the 6M steel rail (1) is milled in one go using a gantry milling machine, with a roughness of ▽3.2; 14# channel steel (2) and 20mm thick steel plate (3) are welded into a basic frame according to the drawings and site requirements (the specific form can be changed according to the site conditions and load-bearing requirements); after the site is leveled, civil excavation is carried out, the civil foundation is prefabricated, and the anchor plate is pre-buried; the welded frame is welded to the anchor plate, and a level ruler is used for initial alignment; two milled steel rails (1) are grouped together, welded and installed on the basic frame in parallel, and a level gauge is used for alignment (the accuracy is 0.5mm per meter allowable deviation, and the overall allowable deviation is 2.5mm), and after alignment is completed, they are welded to the frame; finally, concrete (4) is poured, and according to the concrete grade, it can be used normally after curing for a corresponding number of days.
[0013] When in use, the workpieces to be repaired and assembled are placed on the platform. After alignment, they are clamped in the gaps of double-row tracks, and then riveted and welded and assembled by benchwork to ensure accuracy.
[0014] The utility model significantly reduces the labor input of grinding, clamping, alignment and the like in the assembly and repair process, thereby improving the qualified rate of finished products.
[0015] The utility model is designed based on a T-slot assembly platform and a traditional steel plate assembly platform, is superior to the traditional assembly platform and has various advantages of the T-slot assembly platform; the cost is lower than the T-slot platform and the assembly accuracy is higher than the traditional steel plate platform.
