Omega-shaped sliding block type rapid inspection fixture for inspecting degree of symmetry of elastic strip and inspection method

Abstract

The invention discloses an omega-shaped sliding block type rapid inspection fixture for inspecting degree of symmetry of an elastic strip and an inspection method. The inspection fixture comprises a base, a reference locating plate, a reference shaft and sliding blocks, wherein the reference locating plate, the reference shaft and the sliding blocks are arranged on the base, the reference shaft is fixedly installed on the center line of the base, the sliding blocks are symmetrically installed on the left side and the right side of the reference shaft, a pointer is arranged on each sliding block, and scale marks corresponding to the pointers are arranged on the base. Compared with the prior art, the omega-shaped sliding block type rapid inspection fixture has the positive effects that the measurement flow is simplified, the pointers are matched with the scales of dial plates after the elastic strip is in place, no vernier caliper is needed in use, calculation is not needed, and the amplitudes of swing of the pointers are directly used to measure whether the degree of symmetry of the elastic strip is over the limit or not.

Description

technical field [0001] The invention relates to a slider-type rapid inspection tool for the symmetry of an ω-shaped spring bar and an inspection method. Background technique [0002] The existing inspection method for the symmetry index in the ω-shaped spring is too cumbersome and cannot be quickly detected in mass production. The original detection method is as follows: figure 1 As shown, first use professional molds and vernier calipers to detect and record the left dimension a1, then detect and record the right dimension a2, and calculate the absolute value of a1-a2 according to the recorded results as the value of the symmetry of the ω elastic strip. A value less than the specified value is qualified. This measurement method requires the operator to be trained in the use of the vernier caliper and requires the operator to simultaneously record and calculate during the measurement process. Contents of the invention [0003] In order to overcome the above-mentioned sho...

[0002]The existing inspection method for the symmetry index in the ω-shaped spring is too cumbersome and cannot be quickly detected in mass production. The original detection method is as As shown in Figure 1, the left Record the side dimension a1, then detect and record the right dimension a2, and calculate the absolute value of a1-a2 according to the recording result as the value of the symmetry of the ω elastic bar. If the value is less than the specified value, it is qualified

This measurement method requires the operator to be trained in the use of vernier calipers and requires the operator to record and calculate at the same time during the measurement process
