Embodiment 1

[0027] Embodiment one, see figure 1 , a drop impact test device, including a test piece resting plate 1. A column 2 is arranged on the shelf plate 1 of the test piece. The lower end of the column 2 is screwed to the shelf plate 1 for the test piece. The column 2 is provided with a ruler 21 . The upper end of the column 2 is provided with a hanging rod 3 . One end of the hanging rod 3 is slidably sleeved on the column 2 . The hanging rod 3 is locked together with the column 2 through the locking bolt 31 . The other end of the hanging rod 3 is provided with a drop ball storage tube 4 . The drop ball storage pipe 4 extends up and down. The drop ball storage pipe 4 is removably connected with a support pin 8 . The supporting pin 8 is located on the axial section of the falling ball storage pipe 4, that is, on the vertical plane passing through the axis of the falling ball storage pipe.

[0028] see figure 2 , the inner diameter D1 of the drop ball storage tube is equal t...

Embodiment 2

[0029] Embodiment two, see image 3 , The difference with the first embodiment is: it also includes a gun 5 and a fixed-point recovery mechanism 9 for the bracket pins. The gun 5 is supported on the UUT shelf 1 through the support rod 57 . The gun 5 includes a gun body 51 and a gun barrel 52 provided on the gun body 51 .

[0030] The drop ball storage pipe 4 is provided with a shooting through hole 41 .

[0031] The supporting pin recovery mechanism 9 includes a base 91 and a supporting pin recovering plate 92 . The base 91 is fixed on the DUT resting board 1 . The bracket recovery plate 92 is connected to the side of the base 91 facing the bracket through a spring 93 . The bracket recovery plate 92 is provided with a bracket fixing hole 94 . Gun barrel 52, shooting through hole 41, bracket pin 8 and bracket pin fixing hole 94 four are located on the same straight line.

[0032] see Figure 4 , The inner end face of the bracket pin 8 is provided with a bullet accommodatin...

Embodiment 3

[0048] Embodiment three, the difference with embodiment two is: see Figure 9 , the difference between the inner diameter D1 of the dropped ball storage tube minus the diameter D2 of the dropped steel ball is 2 mm. The length L of the support pin located in the drop ball storage tube is half of the inner diameter D1 of the drop ball storage tube.

Abstract

The invention relates to a test device, especially to a falling impact test device. The falling impact test device comprises a to-be-tested object accommodating plate, a column and a hanging rod, wherein the column is arranged on the to-be-tested object accommodating plate, the hanging rod is connected with the column in a liftable manner, the hanging rod is equipped with a falling ball storage pipe which can extend in the vertical direction, the falling ball storage pipe is detachably connected with a holder pin, and the column is equipped with a scale. Via the falling impact test device provided by the invention, the height of a falling ball can be conveniently obtained, and the problem that the height of the falling ball is inconvenient to obtain via a present drop hammer test device is solved.

Description

technical field [0001] The invention relates to a test device, in particular to a drop impact test device. Background technique [0002] According to QC / T15-92 "General Test Methods for Automotive Plastic Products" 5.7.3.2 Drop Impact Test Requirements and Q / JLYJ7110192A-2010 "Test Specifications for Temperature Resistance of Plastic Parts for Interior and Exterior of Automobiles" 6.1 Low Temperature Impact Resistance Test Regulations: Plastic parts Placed at room temperature for 6 hours, after being subjected to a low temperature of -30°C for 6 hours, within 60 seconds, a steel ball with a diameter of 60 mm and a weight of 0.9 kg was dropped from a height of 150 mm to impact 3 different positions on the surface of the sample. It is necessary to conduct an impact test on the plastic parts of the car to detect the impact resistance of the plastic parts. The existing common equipment for drop impact test is drop weight testing machine. However, the drop weight testing machin...
