A checking device for torsion beam welding structure

Abstract

The invention discloses a gauge device for a torsion beam welding structure. The gauge device comprises a base. Height-adjustable supports are symmetrically arranged on the upper surface of the base; longitudinal sliding rails are arranged on the upper ends of the height-adjustable supports; transverse sliding rails are slidably arranged at intervals between the longitudinal sliding rails; sliding blocks corresponding to four positioning holes in the lower end surface of a torsion beam are arranged on the transverse sliding rails at intervals; and the upper end of each sliding block is provided with a pressure sensor. According to the gauge device, the position and height can be adjusted, and result can be read directly, thereby providing very convenient condition for detection of the torsion beam; the gauge device is improved a lot in time and cost compared with a convention gauge, is good in universality, and can be applied to common stamping welding pieces only by determining 4 planar points; errors due to human factors can be prevented, and detection precision is improved; and the gauge device is simple to operate, obvious in effect and low in cost.

Description

technical field [0001] The invention relates to the field of automobile testing fixtures, in particular to a checking fixture device for torsion beam welding structures. Background technique [0002] The specific definition of inspection tools can be understood as simple tools used by industrial production enterprises to control various sizes of products (such as aperture, space size, etc.), improve production efficiency and control quality, and are suitable for mass-produced products, such as auto parts , to replace professional measuring tools, such as calipers, thread plug gauges, outer diameter calipers, etc. The design of a inspection tool needs to have an obvious feature, that is, it has adjustability. Most parts can be adjusted to meet the inspection of different types of products, and high precision needs to be ensured. [0003] Stamping and welding structures are widely used in the automotive field. Various structures that meet different needs can be formed by stam...

Problems solved by technology

[0005] The tooling positioning of the torsion beam welding structure is an important factor to ensure product quality, but because of the large overlapping structure and irregular shape, the tooling positioning is more complicated, and errors often occur, so the detection of the torsion beam structure is particularly critical. Finding problems in time through sampling and testing products, and then adopting solutions to solve them is the key means to avoid greater losses
