[0023] A limiting plate 406 is fixedly connected to the bottom of the sliding block 405; rotating rollers 407 are installed on the opposite surfaces of the limiting plate 406; a connecting frame 409 is installed on the side frame body of the structural frame 403 close to the main board 1; a fixed shaft 410 is fixedly connected to the end of the frame body of the connecting frame 409; a rotating ring 411 is sleeved and installed on the outer section of the cross-section of the fixed shaft 410; a rotating rod 412 is fixedly connected to the rotating ring 411; a pushing block 413 is installed at the rotating end of the rotating rod 412; the horizontal plane where the top end face of the conveyor belt 408 is located coincides with the horizontal plane where the top end face of the main board 1 is located; the rotation trajectory of the pushing block 413 does not intersect with the operation trajectory of the drilling device 3; a clamping groove 416 is opened at the central position of the top of the main board 1; the opening space of the clamping groove 416 communicates with the opening space of the installation groove 401; the horizontal plane where the bottom end face of the inner wall of the installation groove 401 is located is lower than the horizontal plane where the bottom end face of the inner wall of the clamping groove 416 is located; a bidirectional lead screw 414 is installed in the opening space on one side of the sliding groove 404; the sliding blocks 405 are sleeved on the outer sections of both ends of the bidirectional lead screw 414; a driving motor 415 is installed on the frame body of the structural frame 403; the output shaft of the driving motor 415 is connected to the bidirectional lead screw 414;

[0024] During operation, in the process of manufacturing the cylinder block of a hydraulic cylinder, a drilling device is required to drill the cylinder block housing to facilitate subsequent assembly operations. When the above-mentioned drilling device for machining hydraulic cylinders is in use, due to the large mass of the cylinder block, the loading and unloading operations of the cylinder block are extremely inconvenient, and the position of the cylinder block needs to be repeatedly adjusted and moved, resulting in low drilling efficiency and low automation of the cylinder block. In this application, the operation is carried out through an auxiliary drilling device. The cylinder block of the hydraulic cylinder to be drilled is placed on the conveyor belt 408. According to the size of the cylinder block, the drive motor 415 on the structural frame 403 is started, the bidirectional lead screw 414 rotates, and the slider 405 drives the limit plate 406 to move towards each other along the sliding groove 404, so that the rotating roller 407 clamps the outside of the cylinder block, enabling the cylinder block to enter the working range of the installation groove 401 and the clamping groove 416 in a straight line, achieving the effect of automatic loading of the cylinder block. When drilling the next cylinder block, the cylinder block to be drilled moves along with the conveyor belt 408 and contacts the push block 413. As the cylinder block continues to move, the push block 413 drives the rotating rod 412 and the rotating ring 411 to rotate around the fixed shaft 410, so that the cylinder block that has been drilled in the clamping groove 416 is automatically pushed out, and the cylinder block to be drilled enters the inside of the clamping groove 416, achieving the effect of automatic unloading and ensuring the continuity of the drilling operation.

[0025] Please refer to Figure 3-4 As shown, telescopic cylinders 501 are installed on both side frames of the fixed frame 2; a telescopic rod 502 is installed on the structural surface of the telescopic cylinder 501; a clamping frame 503 is fixedly connected to the connecting end of the telescopic rod 502; limit blocks 504 are fixedly connected to the clamping ends of the clamping frame 503; a connecting block 505 is fixedly connected to the side plate of the clamping frame 503 away from the support frame 402; a rotating plate 506 is installed at the end of the connecting block 505 through a pin shaft; a spring 507 is installed on the plate of the rotating plate 506; the other end of the spring 507 is connected to the frame of the clamping frame 503; the spring 507 does not deform when not in operation;

[0026] During operation, after the cylinder block enters the inside of the clamping groove 416, the cylinder block will tilt due to inertia. With the cooperation of the rotating plate 506 and the spring 507, the tendency of the cylinder block to tilt is blocked and it is stably placed in the clamping groove 416, enabling the automatic loading operation to proceed smoothly. Immediately afterwards, the telescopic cylinder 501 is started, and the telescopic rod 502 drives the clamping frame 503 and the limit block 504 to clamp the outside of the cylinder block, so that the cylinder block can be clamped and fixed at the central position of the clamping groove 416. As the drilling equipment 3 operates, the drilling effect of the cylinder block is achieved.

[0027] Working principle: During the production and processing of the cylinder block of a hydraulic cylinder, a drilling device is required to drill the cylinder block housing to facilitate subsequent assembly operations. When the above-mentioned drilling device for hydraulic cylinder processing is in use, due to the large mass of the cylinder block, the feeding and discharging operations of the cylinder block are extremely inconvenient, and the position of the cylinder block needs to be repeatedly adjusted and moved, resulting in low drilling efficiency and low automation of the cylinder block. In this application, the operation is carried out through an auxiliary drilling device. The cylinder block of the hydraulic cylinder to be drilled is placed on the conveyor belt 408. According to the size of the cylinder block, the drive motor 415 on the structural frame 403 is started, the bidirectional lead screw 414 rotates, and the sliding block 405 drives the limiting plate 406 to move towards each other along the sliding groove 404, so that the rotating rollers 407 clamp the outside of the cylinder block, enabling the cylinder block to enter the working range of the installation groove 401 and the clamping groove 416 in a straight line. After the cylinder block enters the inside of the clamping groove 416, the cylinder block will tilt due to inertia. With the cooperation of the rotating plate 506 and the spring 507, the tendency of the cylinder block to tilt is blocked and it is stably placed in the clamping groove 416, achieving the effect of automatically feeding the cylinder block. Immediately afterwards, the telescopic cylinder 501 is started, and the telescopic rod 502 drives the clamping frame 503 and the limiting block 504 to clamp the outside of the cylinder block, enabling the cylinder block to be clamped and fixed at the central position of the clamping groove 416. With the operation of the drilling equipment 3, the drilling effect of the cylinder block is achieved. When performing the drilling operation on the next cylinder block, the cylinder block to be drilled moves along with the conveyor belt 408 and contacts the pushing block 413. As the cylinder block continues to move, the pushing block 413 drives the rotating rod 412 and the rotating ring 411 to rotate around the fixed shaft 410, so that the cylinder block that has been drilled in the clamping groove 416 is automatically pushed out, and the cylinder block to be drilled enters the inside of the clamping groove 416, achieving the effect of automatic discharging and ensuring the continuity of the drilling operation.
