Problems solved by technology

However, in the actual test of the bolts, it is impossible to ensure that the angle is fixed, and in the actual assembly of the bolts, most of them are assembled at 90° to 180°, so the placement method stipulated in this standard cannot simulate the real corrosion situation, and it is easy to cause excess or insufficient functions.

Embodiment 1

[0044] like figure 1 As shown, a bolt corrosion test fixing device includes a No. 1 load plate 1, a No. 2 load plate 2, a rotating shaft 3, and a protractor 6. A number of bolt fixing holes 8 are respectively arranged on the No. 1 load plate 1 and the No. 2 load plate 2. , the rotating shaft 3 is fixed on one end of the No. 1 loading plate 1, and the No. 2 loading plate 2 is hinged to the rotating shaft to realize the relative rotation between the No. 1 loading plate 1 and the No. 2 loading plate 2. The protractor 6 is fixed on the front side of the No. 6. The center of the circle is coaxial with the center of the rotating shaft 3. The two ends of the rotating shaft 3 are coaxially fixed with a No. 1 knob 4 and a No. 2 knob 5, and a pointer 7 is coaxially fixed on the No. 2 knob 5.

[0045] The hole diameters of several bolt fixing holes 8 provided on the No. 1 bearing plate 1 and the No. 2 bearing plate 2 are not completely the same.

[0046] The bolt fixing holes 8 provided...

Embodiment 2

[0050] A kind of corrosion test equipment, it comprises the bolt corrosion test fixing device described in embodiment 1 and horizontal frame, support rod, and bolt corrosion test fixing device is placed on the horizontal frame and supported by the support rod.

Abstract

The invention discloses a bolt corrosion test fixing device which comprises a first bearing plate, a second bearing plate, a rotating shaft and a protractor, and the first bearing plate and the second bearing plate are each provided with a plurality of bolt fixing holes; the rotating shaft is fixed to one end of the first bearing plate, the second bearing plate is hinged to the rotating shaft, and relative rotation of the first bearing plate and the second bearing plate 2 is achieved; and the protractor is fixed to the front side of the second bearing plate and the center of the protractor is coaxial with the axis of the rotating shaft. According to the invention, the angle of the bolt corrosion test can be adjusted, the bolt can be fixed, the accuracy and singleness of the test are ensured, the test result is not influenced by the preparation of the corrosion-resistant material, and the test equipment is not damaged by the preparation of the light material.

Description

technical field [0001] The invention relates to a bolt anti-corrosion fixing device, in particular to a bolt anti-corrosion test fixing device, which is suitable for the technical field of surface engineering, and particularly relates to the research on the corrosion resistance degree of bolts. Background technique [0002] When the car is exposed to highly corrosive environments such as seaside or winter snowmelt adhesion for a long time, if the corrosion resistance of the bolts is not high, the bolts on the bottom of the car will be corroded and broken, causing car quality problems, and may even increase the risk of vehicle collisions. risk, there are potential safety hazards. In a product of Hongqi, the connecting bolts are made of aluminum alloy, and the connecting shell is also made of aluminum alloy. Under normal circumstances, bolts of this material will not easily cause corrosion. However, after the anti-snow agent corrosion test of the aluminum alloy bolts, the bol...
