Description

Technical Field

[0001] This utility model pertains to processing equipment and tooling in the machinery industry, and specifically relates to a multi-process integrated drilling, milling, and reaming hydraulic clamp for irregularly shaped parts. Background Technology

[0002] Irregularly shaped parts refer to parts that do not conform to national or industry standards. They are typically custom-made by companies according to their needs and have irregular shapes or special functions. Therefore, machining irregularly shaped parts, especially polyhedral copper workpieces, is challenging. Because the workpiece is made of copper, manual clamping easily causes deformation. Furthermore, the numerous machining surfaces and the time spent using calipers for clamping, alignment, and tool setting result in low production efficiency. Additionally, the high machining precision of each surface necessitates multiple separate drilling, milling, and reaming operations in the early stages. This requires significant machine tools and personnel, as each operation requires tool setting and alignment, leading to excessively long setup times and considerable labor costs, severely impacting the machining efficiency of irregularly shaped parts. Summary of the Invention

[0011] The working process of this utility model is as follows: When using the multi-process integrated drilling, milling, and reaming hydraulic chuck for irregularly shaped parts, it can operate on several workpieces simultaneously. The first workpiece 36 is placed in the first-order workpiece placement position 36-1 on the support pin 5, and the workpiece is limited by the limiting block 7 and the adjusting limiting block 2. The second workpiece 36 is placed in the second-order workpiece placement position 36-2 on the support pin 21, and the workpiece is limited by the centering shaft 32. The third workpiece 36 is placed in the third-order workpiece placement position 36-3 on the support pin 326, and the workpiece is limited by the limiting block 24. The fourth workpiece is placed in the fourth-order workpiece placement position 36-4, and the fifth workpiece is placed in the fifth-order workpiece placement position 36-5, and the workpieces are limited by the limiting blocks 31 respectively. Then, the pressing head 14 of the pressing rod 13 and the pressing head 16 of the pressing rod 27 are pressed onto the workpiece. The reference sleeve 35 is used to align the workpiece 36 with the tool and fix the coordinate point. Hydraulic system is activated, with oil entering through port 21-1 on panel 1. The oil flows through panel 21, oil circuit base plate 1, panel 2, pad 3, pad 20, and pad 3, supplying oil to hydraulic lever cylinder 12, hydraulic lever cylinder 28, hydraulic push cylinder 24, hydraulic push cylinder 3, and hydraulic push cylinder 4. This causes the piston rods of hydraulic lever cylinder 12 and hydraulic lever cylinder 28 to move, driving the pressure head 14 of pressure rod 13 and the pressure head 216 of pressure rod 27 to press the fourth and fifth workpieces 36. The piston rod of hydraulic push cylinder 24 moves, driving push block 23 towards the workpiece, and with the support of support plate 210, the third workpiece 36 is fixed in position. The process involves: moving the piston rod of hydraulic pusher cylinder 327 to drive pusher block 128 towards the workpiece, pressing the second workpiece 36 under the adjustment of centering shaft 32 of support block 33; moving the piston rod of hydraulic pusher cylinder 4 to drive pusher head 6 towards the workpiece, pressing the first workpiece 36 under the combined action of support plate 19; after all workpieces are pressed, machining the side reference surface and positioning hole of the first workpiece on pad 13; machining one side and side of the second workpiece 36 on pad 20; machining the other side and side of the third workpiece on pad 325; machining the side inclined surface of the fourth workpiece 36 on panel 121; and machining the other side inclined surface of the fifth workpiece on panel 211. This allows for simultaneous drilling, milling, and reaming of different surfaces of five workpieces 36. After machining, oil is discharged from oil port 21-2, allowing the workpieces 36 to be released and removed. This process can be repeated.
