The first sawing part is composed of two first sawing structures, and each first sawing structure comprises a first mounting block, a first X-axis sliding table, a first Y-axis sliding table, a first motor and a first saw blade. The second saw cuts the part and includes second installation piece, second Y axle slip table, X axle fixed plate and two second saw cuts the structure, and the second saw cuts the structure and includes X axle mounting panel, second X axle slip table, second motor and second saw bit. The clamping part consists of two clamping structures, and the clamping structures comprise a third mounting block, a third X-axis sliding table, a lower positioning block, a supporting block, a top block, a hydraulic cylinder and an upper compacting block. The four casting heads can be sawn simultaneously, so that sawing efficiency is improved.

However, the inventors have found that during actual use, the tail portion of the piston blank is not supported and clamped because the lower locating block and the upper compression block are clamped only to the annular head portion of the piston blank. If staff is loose after placing the piston blank on the lower positioning block, the piston blank can fall down under the action of self gravity of the tail part of the piston blank. Therefore, after the piston blank is placed on the lower positioning block, a worker is required to hold the piston blank by hand, so that the piston blank is kept stable until the upper pressing block descends and presses the piston blank on the lower positioning block. The process of placing the piston blank is time consuming and laborious, and there is a potential safety hazard.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Embodiment one:

the clamping structure for the piston blank riser cutting device comprises a clamping structure body, as shown in fig. 1-3, wherein the clamping structure body comprises a mounting block 1, an X-axis sliding table 2, a lower positioning block 3, a supporting block 4, a jacking block 5, a hydraulic cylinder 6 and an upper compacting block 7. This embodiment is an improvement of a piston blank feeder cutter of the utility model of application number CN202211404700.8, and the above-mentioned structure can refer to the related description in the piston blank feeder cutter of the utility model of application number CN202211404700.8, which is not specifically described in this embodiment.

An upper extension plate 8 is fixed to the rear side of the upper pressing block 7. The middle position of the upper extension plate 8 is provided with a first threaded rod 9 in a threaded connection. A first rotating block 10 is fixed at the top end of the first threaded rod 9. The bottom end of the first threaded rod 9 is fixed with an anti-warping plate 11.

A lower extension plate 12 corresponding to the upper extension plate 8 is fixed to the rear side of the lower positioning block 3. The top end of the lower extension plate 12 is provided with a second sliding groove 13 extending back and forth. A screw 14 is rotatably connected to the second chute 13. The front end of the screw rod 14 passes through the lower extension plate 12 and is fixed with a second rotating block 15. The screw rod 14 is externally sleeved with a nut seat 16 which moves along the second sliding groove 13 in a threaded connection manner. The outer side wall of the nut seat 16 is attached to the groove wall of the second chute 13. The top end of the nut seat 16 penetrates out of the second chute 13 and is fixed with a telescopic rod 17. The telescopic rod 17 comprises an outer tube 18 and an inner rod 19. The bottom end of the outer tube 18 is fixedly connected with the top end of the nut seat 16. The top end of the outer tube 18 is provided with a longitudinally extending first chute 20. The bottom end of the inner rod 19 is inserted into the first slide groove 20 and moves along the first slide groove 20. A tightening bolt 21 inserted into the first slide groove 20 for tightening the inner rod 19 is screwed to the outer side wall of the outer tube 18. The top end of the inner rod 19 is positioned outside the first chute 20 and is fixed with a pallet 22. A positioning plate 23 is fixed to the rear side of the top end of the pallet 22.

Working principle: the first threaded rod 9 is rotated by the first rotating block 10, and the first threaded rod 9 can move up and down, so that the warping plate 11 is driven to move up and down. The height of the rocker 11 is adjusted according to the size specification of the piston blank.

By loosening the jack bolt 21, the inner rod 19 can move up and down in the first chute 20, so that the length of the telescopic rod 17 can be adjusted, and after the adjustment, the jack bolt 21 is tightened, so that the telescopic rod 17 can be fixed at the current length. The length of the telescopic rod 17 is changed to drive the supporting plate 22 to move up and down, so that the height of the supporting plate 22 is adjusted according to the size specification of the piston blank.

After the height of the pallet 22 is adjusted, the second rotating block 15 is rotated. The second rotating block 15 drives the screw rod 14 to rotate. The screw rod 14 drives the nut seat 16 to move back and forth along the second chute 13. The nut seat 16 can drive the telescopic rod 17 to move forwards and backwards. The telescopic rod 17 drives the supporting plate 22 to move back and forth. The supporting plate 22 drives the positioning plate 23 to move back and forth. Thereby adjusting the position of the positioning plate 23.

Then the head of the piston blank is placed on the lower positioning block 3, and the tail of the piston blank is supported by the supporting plate 22, so that the piston blank is kept stable. And the rear side of the piston blank is attached to the positioning plate 23. Therefore, the piston blank is positioned rapidly, and the piston blank is prevented from shifting back and forth when being placed, so that errors are generated when the riser on the piston blank is cut. The piston blank is not required to be held by a worker until the piston blank is clamped, the process of placing the piston blank is more time-saving and labor-saving, and the safety is higher. And the upper compressing block 7 compresses the piston blank, and the warping-preventing plate 11 compresses the top end of the tail part of the piston blank. When the upper compressing block 7 is prevented from compressing the piston blank, the tail of the piston blank is prevented from upwarping.

Embodiment two:

the difference from the first embodiment is that the top end of the lower extension plate 12 is not provided with the second sliding groove 13, and the corresponding screw rod 14 and nut seat 16 are not provided. Instead, as shown in fig. 4 and 5, a slide plate 24 is fixed to the bottom end front side of the outer tube 18. The bottom end of the slide plate 24 is attached to the top end of the lower extension plate 12. A T-shaped chute 25 is provided at the top end of the lower extension plate 12. A T-shaped slide block 26 is slidably connected to the T-shaped slide groove 25. The top end of the T-shaped slider 26 is flush with the top end of the lower extension plate 12, and a second threaded rod 27 is fixed. The top end of the second threaded rod 27 passes through the slide plate 24 and is cooperatively connected with a fastening nut 28.

When the telescopic rod 17 needs to be moved back and forth, the T-shaped sliding block 26 can slide back and forth in the T-shaped sliding groove 25 by unscrewing the fastening nut 28. The T-shaped sliding block 26 drives the second threaded rod 27 to move back and forth. The second screw moves the slide plate 24 back and forth. The slide plate can drive the telescopic rod 17 to move forwards and backwards.
