Problems solved by technology

Since the outer surface of the automobile body or parts is mostly an irregular surface, it is a very laborious and cumbersome job to adjust the position between the force direction of the load loading device and each measuring point, and the rigid points that need to be tested involve The inside and outside of the body or parts, and there are a lot of them. Usually, because each measuring point is different, it is necessary to constantly adjust the position, angle and direction of the loading device. The rigidity test cycle of only one body and accessories needs at least about 15 working days, time-consuming and labor-intensive

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0017] see figure 1 The shown cantilever universal loading device includes an X-direction feed mechanism, a Z-direction feed mechanism, a universal rotation mechanism and a loading mechanism.

[0018] The X-direction feed mechanism includes a horizontal X-direction screw 3 and an upright column 7; the two ends of the X-direction screw 3 are respectively fixed on the X-direction left screw seat 2 and the X-right screw seat 22, so The left end of the X-direction screw 3 is radially fixedly connected to the X-direction feed handwheel 1 through a key; the left end of the lower part of the column 7 is fixed with an X-direction screw nut 6 by welding or screws, and the X-direction screw 3 passes through and Cooperating w...

Abstract

The invention discloses a universal loading device for a cantilever. The universal loading device comprises an X-directional feeding mechanism, a Z-directional feeding mechanism, a universal rotating mechanism and a loading mechanism; the X-directional feeding mechanism comprises an X-directional lead screw and an upright post, and the upright post can move leftwards and rightwards along the X-directional lead screw; the Z-directional feeding mechanism comprises a Z-directional lead screw and a cantilever, and the cantilever can move up and down along the Z-directional lead screw; the universal rotating mechanism comprises a universal rotating base, a second turning hand wheel and a first turning hand wheel; the first turning hand wheel is rotated to drive the universal rotating base to rotate along a first axis clockwise or anticlockwise, and the second turning hand wheel is rotated to drive a second connecting plate to rotate along a second axis clockwise or anticlockwise; and the loading mechanism comprises a loading hand wheel and a loading base, the lower part of the loading base is connected with the second connecting plate, and the loading hand wheel is rotated to drive a force application rod to move leftwards and rightwards. The universal loading device is simple in structure, convenient to operate and strong in practicability.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a cantilever universal loading device. Background technique [0002] At present, the rigidity test of the automobile body or parts adopts a combination tool installed on a fixed support to load each measuring point, and a dial indicator is arranged at the corresponding position of the measuring point to obtain the force of each measuring point - Displacement change curve. Since the outer surface of the automobile body or parts is mostly an irregular surface, it is a very laborious and cumbersome job to adjust the position between the force direction of the load loading device and each measuring point, and the rigid points that need to be tested involve The inside and outside of the body or parts, and there are a lot of them. Usually, because each measuring point is different, it is necessary to constantly adjust the position, angle and direction of the loading device....
