Embodiment 1

[0028] Such as figure 1 As shown, a test bench for wear resistance of sealing strips includes a friction member 1, a left and right moving mechanism 2, a clamping mechanism 3, a loading mechanism 4 and a friction member beam 5; the friction member 1 is fixedly installed on the friction member On the crossbeam 5, the friction member crossbeam 5 is fixedly connected with the loading mechanism 4; the left and right moving mechanism 2 is provided with an installation position 21 for placing a glass sealing strip, and the clamping mechanism 3 is fixed on the installation At both ends of the position 21, the clamping mechanism 3 fixes the glass sealing strip to the installation position 21; the vertical force generated by the loading mechanism 4 presses down the friction member beam 5, and the friction member 1 and the The glass sealing strip fixed on the installation position 21 is frictionally compressed, and the friction sheet 1 slides relative to the glass sealing strip on the i...

Embodiment 2

[0039] Such as Figure 5 and Figure 6 , Embodiment 2 of the present invention provides a test bench for wear resistance of sealing strips. The difference from Embodiment 1 is that there are two friction member columns 6 in total, and the two friction member columns 6 are respectively located on the friction member beam 5 The two ends of the friction member beam 5 are respectively slidably connected to the corresponding friction member column 6 . The left and right ends of the friction member beam 5 are provided with sliders, and the friction member column 6 is provided with a chute matched with the slider.

[0040]The friction member beam 5 can slide along the friction column 6 under the action of the loading mechanism 4 , so that the friction member 1 on the friction member beam 5 contacts the glass sealing strip on the installation position 21 by pressing down.

Embodiment 3

[0042] Such as Figure 7 , Embodiment 3 of the present invention provides a test bench for the wear resistance of sealing strips. The difference from Embodiment 2 is that the loading mechanism 4 includes a pushing cylinder 44 and a loading mechanism bracket 45 for fixing the pushing cylinder 44. The loading bracket 45 is fixed on the friction member column 6 , and the push rod 441 of the push cylinder 44 is fixedly connected with the friction member beam 5 .

[0043] The friction member beam 5 is pushed to slide along the friction member column 6 by pushing the cylinder 44 , thereby pressing down to make the friction member 1 on the friction member beam 5 contact the glass sealing strip on the installation position 21 .

Abstract

The invention discloses a sealing-strip abrasive resistance test bench. The sealing-strip abrasive resistance test bench comprises a friction piece, a lateral-moving mechanism, clamping mechanisms, aloading mechanism and a friction piece beam; the friction piece is fixedly installed on the friction piece beam, and the friction piece beam is fixedly connected with the loading mechanism; an installing position for containing a glass sealing strip is arranged on the lateral-moving mechanism; the clamping mechanisms are fixed at the two ends of the installing position and used for fixing the glass sealing strip on the installing position; vertical force generated by the loading mechanism presses the friction piece beam, the friction piece and the glass sealing strip fixed on the installing position are subjected to friction and pressed, and the friction piece and the glass sealing strip on the installing position generate relative sliding under the effect of the lateral-moving mechanism.According to the sealing-strip abrasive resistance test bench, the abrasive resistance test efficiency is improved, the test cost is saved, and the period is shortened.

Description

technical field [0001] The invention relates to a test bench, in particular to a sealing strip abrasion resistance test bench for testing the abrasion resistance of the door glass sealing strip. Background technique [0002] Whether the door glass sealing strip is smooth or frosted, it will experience countless frictions when the glass is raised and lowered. If the wear resistance is not good, the PVC on the surface of the sealing strip will be worn or the soft hair will fall off, and abnormal noise will occur when the door glass is raised and lowered. Generally speaking, the door glass sealing strip will not be tested for wear resistance alone, but will be tested for overall performance together with the reliability of the vehicle. However, such a test takes a long time, and it is generally difficult to find problems with the sealing strip. Contents of the invention [0003] The object of the present invention is to provide a test bench for wear resistance of sealing stri...
