[0029] When the rotating rod 1 22 and the rotating rod 24 rotate, the worm 25 is driven to rotate synchronously, so that the worm 25 is meshed with the worm wheel 26, and the worm wheel 26 drives the sleeve 27 to rotate synchronously, so that the threaded rod 1 28 moves upward on the inner wall of the sleeve 27, and the threaded rod 1 28 drives the placement table 31 to move upward synchronously, thereby achieving the effect of adjusting the height.

[0030] like Figure 2 , Figure 4 As shown, the right end of the placement table 31 is fixedly connected to a motor 2 32, the output end of the motor 2 32 is fixedly connected to a bidirectional threaded rod 1 33, the left end of the bidirectional threaded rod 1 33 is rotatably connected to the left end of the inner cavity of the placement table 31, the left and right parts of the outer wall of the bidirectional threaded rod 1 33 are threadedly connected to a slider 1 34, the outer wall of the slider 1 34 is slidably connected to the inner cavity of the placement table 31, the top of the slider 1 34 is fixedly connected to the bottom end of the mounting plate 41, the front end of the placement table 31 is fixedly connected to a motor 35, the output end of the motor 35 is fixedly connected to a bidirectional threaded rod 2 36, the rear end of the bidirectional threaded rod 2 36 is rotatably connected to the rear end of the inner cavity of the placement table 31, the front and rear parts of the outer wall of the bidirectional threaded rod 2 36 are threadedly connected to a slider 2 37, the outer wall of the slider 2 37 is slidably connected to the inner cavity of the placement table 31, and the top of the slider 2 37 is fixedly connected to the bottom end of the mounting plate 41.

[0031] Start motor 2 32 and motor 3 35, and motor 2 32 drives bidirectional threaded rod 1 33 to rotate, so that slider 1 34 slides on the outer wall of bidirectional threaded rod 1 33, and at the same time motor 35 drives bidirectional threaded rod 2 36 to rotate, so that slider 2 37 slides on the outer wall of bidirectional threaded rod 2 36, thereby slider 1 34 and slider 2 37 drive mounting plate 41 to move, and mounting plate 41 drives clamping plate 42 to move synchronously, and when the outer wall of clamping plate 42 is in tight contact with the outer wall of engine housing, motor 2 32 and motor 3 35 can be closed, so as to achieve the effect of clamping and positioning.

[0034] The working principle of the utility model is as follows: when in use, the engine housing to be processed is placed on the cushion block 38, and then the motor 2 32 and the motor 35 are started, and the motor 2 32 drives the bidirectional threaded rod 1 33 to rotate, so that the slider 1 34 slides on the outer wall of the bidirectional threaded rod 1 33, and at the same time, the motor 35 drives the bidirectional threaded rod 2 36 to rotate, so that the slider 2 37 slides on the outer wall of the bidirectional threaded rod 2 36, thereby making the slider 1 34 and the slider 2 37 drive the mounting plate 41 to move, and the mounting plate 41 drives the clamping plate 42 to move at the same time.

The motor 1 21 drives the rotating rod 1 22 to rotate, and the rotating rod 1 22 drives the transmission belt 23 to rotate synchronously. The transmission belt 23 drives the rotating rod 24 to rotate synchronously, thereby making the rotating rod 1 22 and the rotating rod 24 drive the worm 25 to rotate synchronously, so that the worm The rod 25 is meshed with the worm gear 26, and the worm gear 26 drives the sleeve 27 to rotate synchronously, so that the threaded rod 28 moves upward on the inner wall of the sleeve 27, and the threaded rod 28 drives the placement table 31 to move upward synchronously, thereby adjusting the height. At the same time, the placement table 31 drives the limiting rod 29 to slide synchronously on the inner wall of the motor 21, and the limiting rod 29 limits the placement table 31 to prevent the placement table 31 from falling off, thereby achieving a limiting effect.
