As shown in fig. 1 to 5, the automatic overturning box for the engine shock pad comprises a box body 1, wherein a guide rail 2 and a motor 3 are respectively installed on the left side inside the box body 1; the motor 3 is connected with a short shaft 4, and a cam 5 and an incomplete gear 6 are respectively arranged on the short shaft 4; the right upper end of the cam 5 is abutted with a connecting rod 7 which is vertically and slidably mounted on the guide rail 2, the upper end of the connecting rod 7 is connected with a bearing plate 8, and the right side of the bearing plate 8 is provided with a convex part 8 a.

Incomplete gear 6 meshes has straight-toothed gear 9, and straight-toothed gear 9 is connected with cross axle 10, install bevel gear 22 on the cross axle 10, bevel gear 22 meshes No. two bevel gear 11, and No. two bevel gear 11 is connected with vertical axis 12.

The transverse shaft 10, the vertical shaft 12 and the short shaft 4 are all arranged in the box body 1 through bearing seats.

A convex block 11a is arranged at the eccentric position of the upper end surface of the second bevel gear 11, and a bottom groove 1a and a top groove 1b are correspondingly arranged at the bottom and the top of the right side of the box body 1 respectively; a vertical frame 23 is arranged in the bottom groove 1a in a sliding mode, the vertical frame 23 is connected with a rack 13, the rack 13 is fixedly connected with a matching frame 14, and a matching groove 14a for installing the protruding block 11a in a sliding mode is formed in the matching frame 14.

A top plate 15 is arranged in the top groove 1b in a sliding mode, and a left shaft 16 and a right shaft 17 are respectively arranged on the top plate 15 through bearing seats; a third bevel gear 18 and a transmission gear 19 meshed and matched with the rack 13 are arranged on the right shaft 17; the left part and the right part of the left shaft 16 are respectively and correspondingly provided with an assembly frame 20 and a fourth bevel gear 21; the fourth bevel gear 21 is meshed with the third bevel gear 18; the assembly frame 20 is provided with a U-shaped clip plate 20a at both the front and rear sides.

In practice, as shown in fig. 6 and 7, a chain 23 capable of being conveyed from back to front is provided, a plurality of loading rods 24 are mounted on the chain 23, and a loading box 25 with an opening at the right side is connected to the right side of each loading rod 24. The bottom of each loading box 25 is provided with a through groove. Each cassette 25 is used to load one engine cushion and to transport the engine cushion from the rear to the front by means of the chain 23.

In the present invention, the right portion of the assembly frame 20 and the projecting portion 8a can be displaced from each other in the vertical direction at the highest limit position. The upper part of the cam 5 is provided with a distal arc edge 5 a. The transmission gear 19 can be self-locked by its own weight.

Before use, the present invention is placed on the right side of the chain 23.

In particular use, each time a loading box 25 is conveyed directly above the support plate 8, it can pass through

In actual processing, the motor 3 drives the cam 5 and the incomplete gear 6 to rotate for one circle, the rotation of the cam 5 can drive the connecting rod 7 and the bearing plate 8 to slide up and down in a reciprocating manner once in the vertical direction, wherein the bearing plate 8 moves upwards to lift the engine shock pad loaded in the loading box 25 upwards, and when the far arc edge 5a rotates to be abutted against the connecting rod 7, the bearing plate 8 and the lifted engine shock pad are located at the upper limit position to stop.

In the stop process of the bearing plate 8, the incomplete gear 6 is in meshed transmission with the straight gear 9, the second bevel gear 11 can rotate for one circle at a constant speed under the transmission action of the bevel gears, and the vertical frame 23 and the rack 13 can slide in a left-right reciprocating manner once in the horizontal direction under the sliding fit action; during the sliding process of the rack 13, the following four steps can be sequentially executed:

in the first step, during the first half of the leftward sliding of the rack 13, the transmission gear 19, the top plate 15 and the assembly frame 20 can be pushed leftward until the top plate 15 slides to the left limit position of the top groove 1 b. In this process, the assembly frame 20 slides leftward and can limit the engine cushion located on the support plate 8 together with the two clamping plates 20a, and push the engine cushion leftward away from the support plate 8.

And secondly, in the second half process of leftward sliding of the rack 13, the top plate 15 cannot slide leftward, so that the transmission gear 19 can rotate constantly, and under the transmission action of the bevel gear, the whole assembly frame 20 and the engine shock pad rotate 180 degrees together, so that the engine shock pad is turned over once.

Thirdly, in the first half process of the rightward sliding of the rack 13, the transmission gear 19, the top plate 15 and the assembly frame 20 can be pushed to the right side, the engine damping pad slides to the right side along with the assembly frame 20 under the static friction force, and when the assembly frame 20 moves over the bearing plate 8, the engine damping pad can be retained on the bearing plate 8 because the engine damping pad is blocked by the protruding part 8 a.

Fourthly, when the top plate 15 slides rightwards to the limit position, the assembly frame 20 completes 180-degree rotation reset.

After the above four steps are completed, the support plate 8 stops and drives the turned engine damping pad to descend together, so that the engine damping pad returns to the original loading box 25 again, and subsequent inspection is facilitated.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
