Embodiment Construction

[0026] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:

[0027] Such as Figure 1~6 As shown, an internally supported positioning point solid welding device includes two longitudinal beams 1 placed in parallel at a certain distance, and two beams 2 are respectively arranged at the two ends of the two longitudinal beams 1, and the longitudinal beams 1 are horizontal beams. The section is a hollow square steel, and the shape of the beam 2 is an inverted "]" shape.

[0028] A plurality of evenly distributed grooves 11 (fourteen in total in the present invention) are formed on the upper end surfaces of the two longitudinal beams 1, and a plurality of through holes 12 are formed between the two grooves 11 on the upper end surfaces of the two longitudinal beams 1 (four in total in the present invention), form the threaded hole screwed into the set bolt 4 at the lower end faces of the two longitudinal beams 1 and the through...

Abstract

The invention discloses an interior bracing type locating point solid welding device. The interior bracing type locating point solid welding device comprises two longitudinal beams arranged at a certain distance and in parallel, two cross beams are arranged at two ends of the two longitudinal beams respectively, the longitudinal beam is square steel with hollow cross section, a plurality of grooves distributed uniformly are formed in the upper end surface of each longitudinal beam, a plurality of through holes are formed between two grooves in the upper end surface of each longitudinal beam, a threaded hole in which a positioning bolt is screwed is formed in the lower end surface of each longitudinal beam, corresponding to the through hole, an inverted L-shaped locating plate is arranged at the lower part of the left end of each longitudinal beam, an end plate is arranged at the right ends of two longitudinal beams, an adjusting bolt is fixed with a base plate by a screw hole of the end plate, a locating plate directly faces the base plate, and a square pipe fitting is arranged at the lower parts of the two longitudinal beams and between the locating plate and the base plate. The interior bracing type locating point solid welding device can reduce the locating difficulty of operators, improve the workpiece position precision, reduce the personal error and meet the large-scale batch production.

Description

technical field [0001] The invention belongs to a spot welding fixture, in particular to an inner support type positioning spot welding device. Background technique [0002] Welding is a process and connection method that produces an interatomic bond between two workpieces by heating, pressure, or both. Welding is used in a wide range of applications, both on metals and non-metals. [0003] Metal welding, according to the characteristics of its process, can be divided into three categories: fusion welding, pressure welding and brazing. [0004] In industrial production, due to technological requirements, it is often necessary to weld one or more ear-shaped workpieces with one end open on the surface of a rectangular pipe. Due to the requirements of its installation accuracy, the current conventional method is to mark and align on the surface of the longitudinal arm of the spot welding device, and then weld the free end of the ear-shaped workpiece with one end open on the s...
