Embodiment 1

[0025] see figure 1 and 3 , in an embodiment of the present invention, a device for detecting the performance of an automobile engine baffle, comprising a lifting box 1 and a ball guide box 22, a ball discharge cylinder 12 is supported and fixed on the top of the ball guide box 22 by a support rod 9, and the ball The inner side of the discharge cylinder 12 cooperates and slides to be provided with a pusher piston rod 10, and the left end of the ball discharge cylinder 12 is provided with a first telescopic cylinder 8 for promoting the push ball piston rod 10 to move in the ball discharge cylinder 12, and the ball discharge cylinder 12 The top of the top is connected with a ball entering cylinder 13, and the left side of the ball guiding box 22 is also provided with a circulation conveying mechanism for conveying the impact ball 11 at the bottom of the ball guiding box 22 to the ball entering the cylinder 13. The inner bottom right side of 22 is provided with guide edge 23, co...

Embodiment 2

[0029] see Figure 1-4 , the difference between this embodiment and embodiment 1 is:

[0030] In this embodiment, the ball discharge cylinder 12 is a cylindrical cylinder structure arranged horizontally and opened at the right end, and the ball inlet cylinder 13 is a cylindrical cylinder structure arranged vertically and connected to the inner cavity of the ball discharge cylinder 12 at the lower end, so The inner diameters of the ball discharge cylinder 12 and the ball entry cylinder 13 are the same, so that the impact ball 11 falls into the ball discharge cylinder 12 from the ball entry cylinder 13; Figure 4 As shown, the ball pushing piston rod 10 is a cylindrical structure that is slidably connected with the inner cavity of the ball discharge cylinder 12, and the right end of the ball pushing piston rod 10 is provided with an arc-shaped groove 27, and through the arc-shaped groove 27 The effect of promoting the impact ball 11 can be improved.

[0031] In this example, i...

Abstract

The invention relates to the field of automobiles, in particular to a device for detecting the performance of an automobile engine baffle, which includes a lifting box and a ball guide box. A ball discharge cylinder is supported and fixed on the top of the ball guide box through a support rod. The inner side of the ball discharge cylinder is The ball pushing piston rod is arranged for sliding, the left end of the ball discharge cylinder is provided with a first telescopic cylinder, the top of the ball discharge cylinder is connected with a ball entry cylinder, and the left side of the ball guide box is also provided with a bottom for the ball guide box. The circular conveying mechanism for the impact ball to the ball entering the cylinder, the right side of the inner bottom of the ball guide box is provided with a sliding seat, the top of the sliding seat is provided with a stand, and the ball guide box is also provided with a mechanism for pushing the stand and sliding seat. For the third telescopic cylinder that moves as a whole, the left side of the stand supports a mounting plate through an angle adjustment mechanism, and the left side of the mounting plate supports an engine baffle fixing frame through a diagonal brace. The invention is convenient for cyclic impact test and dynamic adjustment, improves the accuracy and effect of the test, and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a device for detecting the performance of an automobile engine baffle. Background technique [0002] The car engine guard (baffle) is an engine protection device designed according to various models. Its design is first to prevent the engine from being wrapped by mud, and secondly to prevent the engine from being hit by the uneven road during driving. engine damage. Through a series of designs, the service life of the engine can be extended, and the engine can be prevented from breaking down due to external factors during travel. [0003] Automobile engine baffles need to be tested for performance during mass production. The existing performance testing devices for automobile engine baffles are not convenient for cyclic impact tests and dynamic adjustments, which affect the accuracy and effect of the test. There are limitations and need to be tested. Improvements to overcome the defi...
