[0019] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention relates to a jig for machining engine cylinder blocks, comprising a frame 1, mounting strips 2 symmetrically fixedly mounted on the bottom of the frame 1, and mounting holes 3 through both ends of the mounting strips 2, a platform 4 fixedly mounted on the top of the frame 1, a placement plate 5 fixedly mounted on the top center of the platform 4, a control switch 6 fixedly mounted on the outer center of the frame 1, and an adjusting clamping assembly 7 installed inside the frame 1, with the top of the adjusting clamping assembly 7 extending to the top of the platform 4;

[0020] The adjusting clamping assembly 7 includes a strip frame 8, which is fixedly installed in the middle of the bottom of the frame 1. An adjusting motor 9 is fixedly installed on one side of the strip frame 8. A drive double-acting screw 10 is rotatably installed inside the strip frame 8. The output shaft of the adjusting motor 9 passes through one side of the strip frame 8 and is fixedly connected to one end of the drive double-acting screw 10. A drive threaded sleeve 11 is symmetrically threaded inside the strip frame 8 and outside the drive double-acting screw 10. A positioning slider 2 is symmetrically fixedly installed outside the drive threaded sleeve 11. 1. A positioning groove 22 is symmetrically opened through the outer side of the strip frame 8, and the positioning slider 21 is slidably installed inside the positioning groove 22. A connecting block 12 is fixedly installed on the top of the drive threaded sleeve 11, and a transmission rack 13 is fixedly installed on the top of the connecting block 12. Openings 14 are opened through both sides of the frame 1, and the ends of the two transmission racks 13 that are far apart from each other are movably opened through the openings 14 and extend to the bottom of the frame 1. The tops of the ends of the two transmission racks 13 that are close to each other are meshed with transmission gears 15.

[0021] A bidirectional transmission screw 16 is fixedly installed inside the transmission gear 15, and the two bidirectional transmission screws 16 are symmetrically rotated and installed inside the frame 1. A transmission threaded sleeve 17 is symmetrically threaded on the outer side of the bidirectional transmission screw 16. A movable rod 18 is fixedly installed on one side of the transmission threaded sleeve 17. A positioning slide sleeve 23 is fixedly installed on the side of the transmission threaded sleeve 17 away from the movable rod 18. A positioning slide rod 24 is slidably installed inside the positioning slide sleeve 23. One end of the positioning slide rod 24 is fixedly connected to the inner wall of the frame 1. A positioning block 25 is fixedly installed on the other end of the positioning slide rod 24. The positioning block 25 is fixedly installed on the bottom of the platform 4.

[0022] During use, the interaction of the mounting strip 2, the fixed mounting hole 3, the frame 1, the platform 4, the placement plate 5, the control switch 6, and the adjusting clamping assembly 7 enables the engine block machining fixture to simultaneously fix and clamp both ends of the engine block, improving machining stability and facilitating better practicality. Furthermore, the interaction of the positioning slider 21 and the positioning groove 22 ensures better stability when the drive threaded sleeve 11 moves, thereby ensuring that the adjusting clamping assembly 7 can work stably.

[0023] Working Principle: During operation, firstly, fixing bolts matching the diameter of the fixing mounting hole 3 are used to fix the mounting strip 2, thus fixing the entire fixture. Then, the engine block to be clamped is placed on top of the placement plate 5, with both ends of the engine block positioned between the two clamping seats 20. Next, the adjusting motor 9 is started, driving the drive double-acting screw 10 to rotate. The drive double-acting screw 10 drives the drive threaded sleeve 11 to move. The drive threaded sleeve 11 drives the positioning slider 21 to slide inside the positioning groove 22, ensuring better stability during movement. Simultaneously, the drive threaded sleeve 11 drives the transmission rack 13 to move via the connecting block 12. The transmission rack 13 drives the transmission gear 15 to rotate, and the transmission gear 15 drives the transmission... The bidirectional screw 16 rotates, driving the transmission threaded sleeve 17 to move. The transmission threaded sleeve 17 drives the positioning slide sleeve 23 to slide outside the positioning slide rod 24, ensuring better stability during movement. Simultaneously, the transmission threaded sleeve 17 drives the movable rod 18 to slide inside the strip groove 19, which in turn drives the clamping seats 20 to move. At this time, the four clamping seats 20 move closer to each other in pairs. Through the movement of the four clamping seats 20, the two ends of the engine cylinder block are simultaneously fixed and clamped. After the fixing and clamping is completed, the adjusting motor 9 is stopped. This allows the engine cylinder block machining fixture to simultaneously fix and clamp the two ends of the engine cylinder block during use, improving machining stability and thus facilitating better practicality.
