1 to 3 are schematic diagrams of an engine test stand according to a preferred embodiment of the present invention. The engine test bracket includes a base plate 100 fixed on a platform (not shown), two optical axes 200, a plurality of bearing blocks 300, a fixed plate 400 for installing the engine to be tested, a fixed plate adjusting device 500, four A support column 600 and an engine end plate 700. Wherein, the fixed plate 400 is arranged above the bottom plate 100 at intervals, the optical axis 300 is set between the bottom plate 100 and the fixed plate 400, part of the bearing seat 300 is fixedly installed on the upper surface of the bottom plate 100, and the other part of the bearing seat 300 is fixedly installed on the fixed plate 400. The lower surface of the bearing seat 300 is sleeved on the optical axis 200 and can slide on the optical axis 200 .

As a preferred embodiment, the engine test bracket has two parallel optical axes 200, each optical axis 200 is provided with four bearing housings 300, and a pair of bearing housings 320 spaced from each other are fixed on the bottom plate 100. , and by tightening the locking screws on the pair of bearing seats 320 to make the optical shaft 200 and the pair of bearing seats 320 into a tight fit, so that the optical axis 200 is fixed on the base plate 100 . The rest of the pair of bearing seats 340 are opposite to the bottom surface of the bearing seat 320, the bearing seats 340 are fixed on the fixing plate 400, and can slide relative to the optical axis 200 along the axial direction of the optical axis 200, so that the fixing plate 400 Sliding relative to the bottom plate 100 along the axial direction of the optical axis 200 .

The fixed plate adjusting device 500 is fixed on the platform, and is mainly used for adjusting and controlling the movement of the fixed plate 400 relative to the bottom plate 100 . In this embodiment, the fixing and adjusting device 500 includes a screw hole seat 520 fixed at the rear end of the fixing plate 400, a support seat 540 with a bearing, and a screw rod 560, and the two ends of the screw rod 560 are respectively passed through the screw hole seat 520. And in the bearing of support seat 540. The support base 540 can be fixed on the platform or the ground, or on the bottom plate 100, as long as it can be relatively positioned or fixed. The screw rod 560 is rotated by a common wrench, so that the screw rod 560 interacts with the screw hole seat 520 , so that the fixed plate 400 and the engine 800 mounted on the fixed plate 400 can move back and forth accurately and labor-savingly.

The engine 800 is suspended on the bracket through the above-mentioned four support columns 600 . These four support posts 600 are arranged on the four corners of the fixed plate 400, and each support post 600 includes a screw seat fixed base plate 620, a screw seat 640 fixed on the screw seat fixed base plate 620, a fixed screw rod 660, and a fixed screw rod 660 located on each fixed screw rod. Shock absorbing element 680 and locking element 690 on 660. The fixing screw 660 is installed in the screw seat 640 and can be screwed into and out of the screw seat 640 .

When using these four support columns 600 to hang the engine 800, the engine end plate 700 is fixedly connected to one end surface of the engine 800, and the through holes on the two ends of the engine end plate 700 are respectively sleeved on the two ends of the fixed plate 400 front end. on the two fixing screws 660, and fix the engine end plate 700 on the two fixing screws 600 by nuts and other elements. At the same time, the mounting ears 820 on both sides of the other end of the engine 800 are respectively sleeved on the two fixing screw rods 600 at the rear end of the fixing plate 400, and the bolts 900 are passed through the mounting ears 820 and then rotated into the two fixing screws 600 located at the fixing plate 400. The top of the fixing screw 600 at the rear end of the plate 400. In this way, the engine 800 can be hung on the bracket.

By adjusting the fixing screw 660 to screw it in and out of the screw seat 640, the center height of the engine 800 can be aligned with the center height of the bracket. After the center heights are aligned, the locking elements 690 (such as lock nuts, etc.) are locked to ensure that the center height of the engine 800 remains unchanged during operation. In this way, through the cooperation of the screw seat 640 and the fixed screw 660, the engine 800 can be moved up and down, and the relative height between each fixed screw 660 can be adjusted to adapt to the use of various engine models on the bracket. In addition, each component of the above-mentioned engine test bracket can be manufactured by an ordinary machinery factory, the processing technology is simple, and the production cost is relatively low.

In order to further enhance the versatility of the bracket, the fixed screw rods 660 can be moved in a predetermined direction to suit various engine models.

As shown in Figure 3, two first guiding structures corresponding to the two fixing screw rods 660 located at the rear end of the fixing plate 400 are provided at the rear end of the fixing plate 400. In this embodiment, each first guiding structure It includes two sliding slots 420 parallel to each other and spaced apart on the fixing plate 400, and the sliding slots 420 extend along the vertical direction. Guide elements 670 corresponding to the two sliding slots 420 on the fixing plate 400 are provided on the two screw seat fixing bottom plates 620 at the rear end of the fixing plate 400 . The guide element 670 is inserted into the chute 420, and can slide along the extension direction of the chute 420 in the chute 420. Through the cooperation between the chute 420 and the guide element 670, the two fixing screws 660 located at the rear end of the fixing plate 400 can Move along the direction shown by the arrow I in Figure 3, that is, the front and rear directions.

In addition, the four corners of each screw base fixed base plate 620 are respectively provided with second guide structures. In this embodiment, each second guide structure is a chute 622 opened on the screw base fixed base plate 620. The chute 622 extends along the horizontal direction, and its extending direction is perpendicular to the extending direction of the chute 420 . The guide element 670 is passed through the sliding slot 622, so that the fixing screws 660 can move along the direction indicated by the arrow II in FIG. 3 , ie, the left and right directions.

In particular, in order to ensure the perpendicularity between the end surface of the engine 800 and the coupling, the guide element 670 passing through the two screw seat fixing bottom plates 620 at the front end of the fixing plate 400 is fixed on the fixing plate 400 . In this way, the two fixing screws 660 at the front end of the fixing plate 400 can only move along the left and right directions, while the two fixing screws 660 at the rear end of the fixing plate 400 can move along the left and right directions as well as along the front and rear directions. Through the movement of these fixed screw rods 660, the distance between them can be adjusted so as to adapt to the use of various engine models on the bracket.

At the same time, the movement of these fixing screws 660 can realize the symmetrical arrangement of the elastic support arrangement according to the center of gravity, so that the force on the elastic support arrangement is equal, so that a good vibration damping effect can be obtained.

It can be understood that the above-mentioned bearing seat 300 can also be other optical axis support that is sleeved on the optical axis 200 and can support the fixing plate 400 , as long as it can drive the fixing plate 400 to move along the axial direction of the optical axis 200 .

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
