Assembling and positioning method and device for magnesium alloy LED light box

Abstract

The invention discloses an assembling and positioning method and device for a magnesium alloy LED light box. The method comprises the following steps that (1), positioning holes are drilled; (2), a cylindrical pin is arranged; (3), a diamond pin is arranged; (4), the cylindrical pin and the first positioning hole are assembled; (5), the diamond pin and the second positioning hole are assembled; and (6), inspection and acceptance are conducted. The assembling and positioning device for the magnesium alloy LED light box comprises a light box outer frame and a light box body. The light box body is arranged on the light box frame. The positioning pins are arranged on the light box body. The positioning pins comprise the cylindrical pin and the diamond pin. The light box outer frame is connected with the light box body through the positioning pins. A front baffle is arranged on the light box outer frame. The first positioning hole corresponding to the cylindrical pin and the second positioning hole corresponding to the diamond pin are formed in the front baffle. The assembling and positioning method and device solve the problem of the angular positioning and eliminate the over-positioning, and the interchangeability is guaranteed.

Description

Technical field: [0001] The invention relates to a positioning method and device, in particular to a magnesium alloy LED light box assembly positioning method and device. Background technique: [0002] Magnesium alloy LED light box series products always have docking difficulties when they are combined and assembled in the field. The two cylindrical pins on the box and the two mounting holes on the other box cannot be connected normally. This is due to the large errors accumulated in the manufacturing process of the box , and the product design uses double cylindrical pins for positioning, which does not conform to the positioning principle of mechanical parts design, resulting in over-positioning, resulting in mismatched assembly and installation. The method of replacing the positioning pins or replacing the box is adopted. Because there is no interchangeability, many times Dismantling and assembling components for selection will damage the coating layer on the surface of t...

Problems solved by technology

[0002] Magnesium alloy LED light box series products always have docking difficulties when they are combined and assembled in the field. The two cylindrical pins on the box and the two mounting holes on the other box cannot be connected normally. This is due to the large errors accumulated in the manufacturing process of the box , and the product design uses double cylindrical pins for positioning, which does not conform to the positioning principle of mechanical parts design, resulting in over-positioning, resulting in mismatched assembly and installation. The method of replacing the positioning pins or replacing the box is adopted. Because there is no interchangeability, many times Dismantling and assembling components for selection will damage the coating layer on the surface of the box, and waste time and work, wasting resources; The size of the hole ensures that the design size of the cylindrical pin remains unchanged, which can meet the interchangeability requirements, but it brings new problems. When the two holes are at the maximum limit size, the two positioning pins are at the minimum limit size, and Due to the influence of hole distance error and pin distance error, the matching gap is too large, which causes angular displacement when the cabinets are docked. After the cabinets are combined, it is impossible to ensure that the lamp body is installed on the same plane.
