[0020] Please see Figure 1-4 This utility model provides a technical solution: a clamping device for a magnesium alloy engine cylinder block, including a machining base 1. The upper surface of the machining base 1 has a placement groove 104. Side plates 105 are symmetrically fixedly connected to both ends of the machining base 1.

The lower surface of the guide rails 101 is fixedly connected to the upper surface of the machining base 1. The guide rails 101 are slidably connected with a moving block 1012. The moving block 1012 is threadedly connected with a lead screw 1011. One end of the lead screw 1011 is rotatably connected to the inner wall of the guide rails 101. The upper surface of the moving block 1012 is rotatably connected with a hydraulic cylinder 1013. The upper end of the hydraulic cylinder 1013 is fixedly connected with a clamping arm 1016. The lower surface of the machining base 1 is provided with a limiting mechanism.

[0021] As a technical optimization of this utility model, a screw 1015 is threadedly connected to the lower surface of one end of the clamping arm 1016, and a clamping block 1014 is fixedly connected to the lower end of the screw 1015. The engine cylinder can be clamped and fixed by the clamping block 1014. The screw 1015 can be used to easily replace the clamping block 1014 of different thicknesses, so it can clamp and fix engines of different sizes.

[0022] As a technical optimization of this utility model, the adjustment mechanism includes gear II 204. One side surface of gear II 204 is fixedly connected to the upper end of side plate 105 through a rotating shaft passing through support plate 103. Gear I 203 is meshed with the side surface of gear II 204. A drive mechanism is provided on one side surface of gear I 203. The rotation angle of the processing seat 1 can be easily adjusted by the drive mechanism and gears I 203 and II 204 in the adjustment mechanism, so the engine can be adjusted to different angles for processing.

[0023] As a technical optimization of this utility model, the drive mechanism includes a geared motor 2, which is fixedly installed on the outer surface of one of the support plates 103. One end of the geared motor 2 is fixedly connected to a worm 201, and a worm wheel 202 is meshed with the side surface of the worm 201. One side surface of the worm wheel 202 is fixedly connected to one side surface of the gear I 203. The geared motor 2, worm 201 and worm wheel 202 in the drive mechanism can drive the gear I 203 to rotate.

[0024] As a technical optimization of this utility model, the measuring component includes an angle ruler 402. One side surface of the angle ruler 402 is fixedly connected to the outer surface of another set of support plates 103 via a crossbar 403. The other side surface of the crossbar 403 is provided with a pointer 401. One end of the pointer 401 is fixedly connected to a rotating shaft 4. One end of the rotating shaft 4 passes through the support plate 103 and is fixedly connected to the side plate 105. Through the rotating shaft 4, the pointer 401 and the angle ruler 402, the operator can easily know the angle at which the machining seat 1 drives the engine cylinder block to rotate, which can improve the machining accuracy of the engine cylinder block.

[0025] As a technical optimization of this utility model, the limiting mechanism includes a limiting slide rail 3, a limiting block 302 is slidably connected inside the limiting slide rail 3, a support rod 303 is fixedly connected to the upper surface of the limiting block 302, the upper end of the support rod 303 is fixedly connected to the lower surface of the processing seat 1, an arc plate 301 is symmetrically fixedly connected to the upper surface of the limiting slide rail 3, and one side surface of the arc plate 301 is fixedly connected to the inner surface of the support plate 103 through the support rod 303. The limiting slide rail 3, the limiting block 302 and the support rod 303 can limit the processing seat 1, and improve the stability of the processing seat 1 when it rotates.

[0026] In use, the engine block to be processed is first placed in the placement groove 104 on the upper surface of the processing base 1. Then, the operator rotates the lead screw 1011 inside the guide rail 101 according to the size of the engine block. At this time, the lead screw 1011 pushes the hydraulic cylinder 1013 closer to the engine through the moving block 1012. When the hydraulic cylinder 1013 is located on one side of the engine block, the rotation of the lead screw 1011 is stopped. Then, the hydraulic cylinder 1013 is rotated so that one end of the clamping arm 1016 at the upper end of the hydraulic cylinder 1013 turns towards the engine block. Then, the hydraulic cylinder 1013 is started. 013 will pull the clamping arm 1016, so the clamping block 1014 on the lower surface of one end of the clamping arm 1016 will clamp and fix the engine cylinder block. When the engine cylinder block needs to be rotated, the reduction motor 2 is started. At this time, the reduction motor 2 drives the worm wheel 202 to rotate through the worm 201. The worm wheel 202 drives the side plate 105 and the machining seat 1 to rotate through the gear I 203 and the gear II 204. During this process, the operator can observe the rotation angle of the machining seat 1 and the engine cylinder block through the pointer 401 and the angle ruler 402 at one end of the rotating shaft 4, so as to process the engine cylinder block more accurately.
