DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 , an engine bench test connection plate removal tool, including a base 1, an engine body is placed on the upper end of the base 1, the engine body is an existing well-known technology, and its specific structure and working principle are not elaborated in detail here.

[0021] An arc groove 2 is provided at the upper end of the base 1, and the shape of the arc groove 2 is adapted to the shape of the engine body, and the engine body is located at the upper end of the arc groove 2. By setting the arc groove 2, the cylindrical engine body can be limited to prevent the engine body from rolling forward and backward, which is convenient for limiting the lower connecting plate 4.

[0022] An engine power output terminal 3 is provided at the right end of the engine body, and a connecting disk 4 is provided at the right end of the engine power output terminal 3. A U-shaped frame 5 is fixedly connected to the upper end of the base 1, and the connecting disk 4 is located directly below the U-shaped frame 5. A positioning assembly is provided on the U-shaped frame 5, and the positioning assembly includes a rotating motor 6 fixedly installed at the front end of the U-shaped frame 5. A bidirectional threaded rod 7 is rotatably provided on the U-shaped frame 5, and the front end of the bidirectional threaded rod 7 passes through the U-shaped frame 5 and is fixedly connected to the output end of the rotating motor 6. The rod body of the bidirectional threaded rod 7 is symmetrically slidably sleeved with two threaded sleeves 8. A guide rod is fixedly provided on the U-shaped frame 5, and the guide rod is provided through the two threaded sleeves 8 to ensure that when the bidirectional threaded rod 7 rotates, the threaded sleeve 8 can slide horizontally on the rod body of the bidirectional threaded rod 7.

[0023] When limiting the connection disk 4, the rotating motor 6 drives the bidirectional threaded rod 7 to rotate, driving the two threaded sleeves 8 to move relative to each other, and drives the two positioning plates 10 to move relative to each other through the lower connecting block 9 to clamp and position the connection disk 4.

[0024] The lower end of the threaded sleeve 8 is fixedly connected to a connecting block 9, and the lower end of the connecting block 9 is fixedly connected to a positioning plate 10. Anti-slip pads are fixedly bonded to the opposite ends of the two positioning plates 10. On the one hand, the connecting disk 4 is protected by the elastic contact between the elastic pad and the connecting disk 4, and on the other hand, the limiting effect on the connecting disk 4 is increased by increasing the static friction force.

[0025] The positioning plate 10 is in an arc shape, which matches the shape of the connecting disk 4 , thereby increasing the fitting area between the two and improving the effect of limiting the connecting disk 4 .

[0026] A disassembly assembly is provided at the upper end of the base 1 on the right side of the U-shaped frame 5. Specifically, the disassembly assembly includes a fixing plate 11 fixedly connected to the base 1, a screw hole 12 is provided on the fixing plate 11, a screw rod 13 is slidably connected to the screw hole 12 and the two are threadedly matched, a through hole is provided on the connecting disk 4, and the through hole corresponds to the horizontal position of the screw rod 13. The screw rod 13 is moved to the left to push the engine power output end 3, so that the engine body 3 moves to the left, while the position of the connecting disk 4 remains unchanged, thereby separating the connecting disk 4 from the engine power output end 3.

[0027] A hexagonal slot 14 is formed at the right end of the screw rod 13 . The hexagonal slot 14 is used in conjunction with a hexagonal wrench. The hexagonal wrench is inserted into the hexagonal slot 14 , and the screw rod 13 is rotated by rotating the hexagonal wrench.
