Field of the Invention The present invention relates to an apparatus for testing durability of automotive parts, in particular door opening and closing grommet and wires disposed inside the grommet, and more particularly, external environmental conditions and opening and closing conditions of the door. The present invention relates to a durability test apparatus for automobile parts capable of testing the durability of the test object under the same conditions.

In general, many electric appliances are installed in automobiles. A number of wires are used to connect these electronics and also to connect the electronics to the battery. The wires are fixed and arranged in an uncluttered state and when the wire passes through the hole formed in the body panel Grommets are used to prevent damage to the sheath of the wires by the sharp edges of the holes formed in the panel, or to extend the wires undisturbed from the vehicle body to the side of the swinging door.

The grommet has a ring-shaped grommet formed with a wire through-hole in the center and a fitting groove formed in a hole formed in the body panel on the outer circumferential surface thereof, and flanges fitted to the body panel and the door panel at both ends thereof. The grommet of corrugated pipe shape to connect is distinguished.

Since the tubular grommet described below among the grommet is mounted on the moving part unlike the ring grommet, the durability test of the grommet and the wire penetrating the inside of the grommet must be performed.

Conventional durability test equipments typically turn one end of the grommet and the wire while fixing both ends of the grommet and the wire to grasp the grommet leak, mountability, assembly, flexibility, and flexibility of the wire.

However, the durability test equipment has a problem in that it is difficult to obtain accurate test values because it is different from the operation of various actual car doors because only one side of the grommet and wire gripping portion is adjusted in distance and height.

In addition, since the grommet is always mounted only in a certain direction when the grommet is mounted, there is a problem that the grommet may be twisted to the wire and the stress may be affected if the grommet is slightly angled when the grommet is mounted.

In addition, since the test is always performed under the same temperature and the same environmental conditions, there was a problem that various durability tests cannot be made according to environmental changes.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is the durability test for automotive parts that can be tested for durability of the test object under the same conditions as the external environmental conditions and opening and closing of the door (door) To provide a device.

In order to achieve the object of the present invention as described above, the present invention,

Under the condition that the third fixing nut 184a and the fourth fixing nut 184b fastened to the fixing bolt 182b are unscrewed, the first rotating disk 174a and the second rotating disk 174b may be moved to the first vertical moving hole ( 168a) and the second fixing disk 168b and the first rotating disk 174a and the second rotating disk 174b at the same time, and then the third fixing bolt 182a and the fourth fixing bolt ( The third fixing nut 184a and the fourth fixing nut 184b are fastened to 182b. Here, when the first rotating disk 174a and the second rotating disk 174b are rotated, the fixing direction of the grommet G is adjusted. As described above, when the first rotating disk 174a and the second rotating disk 174b are variable, the first fixed plate 176a and the second rotating disk 174a and the second rotating disk 174b are similarly changed. The fixed plate 176b is also variable.

As described above, when the grommet G and the wire W passing through the grommet G are mounted on the test apparatus 100 under the same condition as the opening and closing conditions of the actual car door, the controller 120 is mounted. Run to test durability of grommet (G) and wire (W). In order to perform the durability test, the chamber 114 is closed by turning the opening / closing door 116. When the chamber 114 is limited by the opening / closing door 116, the controller 120 operates the temperature and humidity controller 122 to maintain a constant temperature and humidity in the chamber 114. The temperature and humidity in chamber 114 are set to maintain a preset temperature and humidity prior to the endurance test. As such, when the temperature and humidity in the chamber 114 maintain a predetermined value, the controller 120 operates the driving cylinder 194 of the driving unit 190. As the driving cylinder 194 operates, the driving cylinder rod ( 196 is extended and retracted repeatedly into and out of the chamber 114, so that the rack gear 197 rotates the pinion gear 193 forward and reverse. At this time, as the drive cylinder rod 196 extends, the pinion gear 193 which is rotated forward by the rack gear 197 rotates the drive shaft 192 forward, and the drive shaft 192 forward rotates. The rotating stage 152 of the connected rotating frame unit 150 is pivoted to one side. In addition, the pinion gear 193 reversely rotated by the rack gear 197 as the drive cylinder rod 196 contracts reversely rotates the drive shaft 192, and the drive shaft 192 reversely rotates. The connected rotary stage 152 is returned. Herein, the number of expansion and contraction times of the driving cylinder 194 is set by the controller 120.

On the other hand, the amount of rotation of the rotating stage 152 is adjusted by the control block 198 mounted on the other end of the drive cylinder rod 196, the control block 198 is mounted on the other end of the drive cylinder rod 196 When the rotating stage 152 has the maximum amount of rotation, and is mounted adjacent to the drive cylinder 194 at the other end of the drive cylinder rod 196 of the control block 198 has a minimum amount of rotation.
