Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a device for measuring the bending, flattening and extension variation of automobile seat steel wires. Background Art

[0002] After the car seat steel wire is bent and formed, it needs to go through a flattening process. After the flattening process is completed, it is also necessary to test whether the extension change of the flattened part is qualified.

[0003] like Figure 2 As shown, the automobile seat steel wire is usually a non-planar structure after being bent and formed, and its left part 91 is tilted upward and cannot be stably placed on the measuring table. The flattened part 92 is located on the right part of the formed steel wire. When using a gauge to measure, the worker needs to hold the workpiece with one hand and hold the gauge with the other hand to measure the extension change of the flattened part. This measurement method is very inconvenient to operate and affects the detection efficiency. Utility Model Content

[0004] In view of the defects existing in the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a device for measuring the extension change of the flattened portion of the formed steel wire for automobile seat bending, which can improve the detection efficiency of the extension change of the flattened portion of the formed steel wire.

[0005] In order to solve the above technical problems, the utility model provides a device for measuring the bending, flattening and extension variation of automobile seat steel wire, which is characterized by comprising a base and a positioning block fixed on the base;

[0006] A scale is fixed on the base, and a slider that can slide left and right and a guide rail for guiding the slider to slide left and right are provided on the base. Graduations for measuring the left and right displacement of the slider are printed on the scale, and a pointer is fixed on the slider;

[0007] The base is provided with a zero position hole, and the slider is provided with a zero position pin that can slide up and down. When the slider slides to the right until the pointer is located directly above the zero position scale of the scale, the zero position pin is located directly above the zero position hole, so that the zero position pin can extend downward into the zero position hole.

[0008] The positioning block is provided with a first cavity groove for placing the left and middle parts of the bent steel wire, and the movable slide block is provided with a second cavity groove for supporting the right part of the bent steel wire.

[0009] The utility model provides a device for measuring the bending, flattening and extension variation of automobile seat steel wires. After the bent steel wire is placed in a cavity groove, the flattening and extension variation of the steel wire can be conveniently and quickly detected by moving a slider, thereby improving detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1It is a schematic structural diagram of a device for measuring the bending, flattening and elongation variation of a steel wire for a car seat according to an embodiment of the utility model;

[0011] Figure 2 It is a top view of the bent steel wire for the car seat. DETAILED DESCRIPTION

[0012] The following is a further detailed description of an embodiment of the utility model in conjunction with the accompanying drawings, but the embodiment is not intended to limit the utility model. All similar structures and similar changes of the utility model should be included in the protection scope of the utility model. The semicolons in the utility model all represent the relationship of and.

[0013] like Figure 1 As shown, a device for measuring the bending, flattening and elongation variation of a steel wire for a car seat provided in an embodiment of the utility model comprises a base 1 and a positioning block 2 fixed on the base 1;

[0014] A scale 4 is fixed on the base 1, and a slider 5 that can slide left and right and a guide rail 3 for guiding the slider 5 to slide left and right are provided on the base 1. A scale for measuring the left and right displacement of the slider 5 is printed on the scale 4, and a pointer 51 is fixed on the slider 5.

[0015] The base 1 is provided with a zero position hole 11, and the slider 5 is provided with a zero position pin 52 that can slide up and down. When the slider 5 slides rightward until the pointer 51 is located directly above the zero position scale of the scale 4, the zero position pin 52 is located directly above the zero position hole 11, so that the zero position pin 52 can extend downward into the zero position hole 11;

[0016] The positioning block 2 is provided with a first cavity groove 21 for placing the left and middle parts of the bent steel wire, and the movable slider 5 is provided with a second cavity groove 53 for supporting the right part of the bent steel wire.

[0017] The embodiment of the utility model is used to measure the bending, flattening and extension variation of the steel wire of the automobile seat, and the method of use is as follows:

[0018] Before testing, slide the moving slider 5 so that the zero position pin 52 on the moving slider 5 falls into the zero position hole 11. At this time, the pointer 51 points to the zero position scale of the scale 4 (that is, the pointer 51 is located directly above the zero position scale of the scale 4);

[0019] During inspection, the zero position pin 52 is pulled out from the zero position hole 11, and then the left and middle parts of the bent steel wire that have been flattened are placed in the first cavity groove 21. At the same time, the slider 5 is pushed to the left to align the right part of the bent steel wire with the second cavity groove 53 on the slider, and then the right part of the bent steel wire is placed in the second cavity groove 53. At this time, the scale indicated by the pointer 51 on the slider 5 is recorded, and the scale is compared with the scale indicated by the pointer 51 when it is at zero position. The difference between the two scale values ​​is the change in the flattening extension of the steel wire.
