Abstract
The invention relates to an apparatus for measuring resistance spot welding splash sizes and a use method and belongs to the spot welding technical field. The apparatus includes a supporting seat, a base plate, a clamping groove and thermal sensitive paper; the base plate is arranged on the supporting seat and is connected with the supporting seat; the clamping groove is arranged on the base plate; the thermal sensitive paper is inserted into the clamping groove, so that a cylinder of which the periphery is closed can be formed; the thermal sensitive paper is arranged at the upper part and the lower part of the cylinder, so that a fully-closed cylinder can be formed; and after spot welding, the thermal sensitive paper is removed, and the proportion of a color-changed area of the thermal sensitive paper to the area of the thermal sensitive paper is measured. With the apparatus and the use method adopted, the sizes of splashes generated when different spot welding techniques are adopted can be accurately compared quantitatively.
Description
Technical field
The invention belongs to spot-welding technology field, particularly relate to a kind of device and using method of measuring resistance spot welding splashing size.
Background technology
Spot welding is a kind of high speed, economic method of attachment, and this method is widely used in the welding of the mild carbon steel products such as automobile cab, metal compartment compound plate, furniture.During product resistance spot welding, in the short time, the interface of weld is melted rapidly, and metal heat increases instantaneously, and the liquid of fusing has little time cooling, forms iron filings and eject from fusion zone under the effect of extraneous pressure, creates spot welding and splashes.Splashing spark, is degrading the working environment of operating personnel, has influence on the safety of operating personnel, adds the risk factors of production scene, and is attached to the surface quality that product surface reduces product.
In order to reduce the size that resistance spot welding is splashed, need the influence factor studying splashing size.In actual production process and laboratory study, due to the size that spot welding is splashed cannot be measured, hinder the further research to splashing size influence factor.Therefore, the method and apparatus that a kind of measuring resistance spot welding splashing size is provided is necessary.
Summary of the invention
Object of the present invention with device and using method that a kind of measuring resistance spot welding splashing size is provided, solve the problem measured and evaluate resistance spot welding splashing size.
A device for measuring resistance spot welding splashing size, comprising: bearing 1, substrate 2, draw-in groove 3 and heat-sensitive paper 4; Substrate 2 is above bearing 1 and be connected with bearing 1; Draw-in groove 3 is side on a substrate 2; Heat-sensitive paper 4 is inserted in draw-in groove 3, forms the cylinder that surrounding is airtight; The upper and lower of cylinder places heat-sensitive paper 4 respectively, forms totally-enclosed cylinder.
Draw-in groove 3 is circular, can the distance of guarantee point weld spacing heat-sensitive paper from around certain, ensure the precision of test result.
Heat-sensitive paper 4 is 3, comprises around cylinder 1 and each 1 of upper and lower surface.
A using method for the device of measuring resistance spot welding splashing size, concrete steps are as follows:
1), under bearing 1 and substrate 2 being placed on resistance spot weld, spot-wedling electrode is made to be in the semi arch place at substrate 2 center;
2) draw-in groove 3 is placed on a substrate 2, form draw-in groove slideway, heat-sensitive paper 4 is inserted in draw-in groove 3;
3) place heat-sensitive paper 4 at the upper and lower surface of draw-in groove 3, form the airtight cylinder that is surrounded electrode points;
4) after resistance electric welding, take off heat-sensitive paper 4, carry out process of taking pictures;
5) image processing software is adopted to calculate the variable color area of heat-sensitive paper 4 total area and heat-sensitive paper 4; Adopt the numerical value of ratio as splashing size of heat-sensitive paper 4 variable color area and heat-sensitive paper 4 total area.
The invention has the advantages that: have employed heat-sensitive paper 4 and be placed on around spot welding point, rapidly, cyclically can insert heat-sensitive paper 4, effectively can contrast the splashing size of different resistance spot welding welding technology.The present invention innovates and adopts heat-sensitive paper 4 to be placed on around spot welding point, can simple and effective Record Comparison resistance spot welding splashing size.
