On the back of the connecting plate 321, a positioning part 3 is provided. In use, the casting is first placed on the worktable 216. After the hydraulic push rod 326 is started, it drives the second slider 323 to slide down in the second slide groove 322 of the connecting plate 321. Through the transmission of the two connecting rods 324 hinged to the second slider 323, the two sliders 312 on the slide rail 311 synchronously drive the fixed plate 314 to move closer to each other. At the same time, the positioning plate 315 connected to the fixed plate 314 is slidably connected to the second slide rod 317 of the rectangular plate 316 to ensure clamping stability and finally realize the rapid clamping and positioning of the casting.
[0029] A specific application of this embodiment is: a horizontal machining center 1 for casting processing: a CNC machine tool with a horizontally arranged spindle, equipped with three linear motion axes X, Y, and Z, and can be equipped with a fourth rotary axis. It can complete multiple processes such as milling, drilling, and boring in one clamping. It is suitable for processing complex castings such as small and medium-sized box-shaped and shell-shaped parts. It has the advantages of convenient chip removal and high machining accuracy. Recommended models include: Nidec OKK HM8000S, with a standard spindle speed of 12000 min-1, which can perform heavy cutting. The X, Y, and Z axes adopt high-rigidity linear roller guides, which have good cutting performance.
[0030] In use, the casting is first placed on the worktable 216, and then the hydraulic push rod 326 is activated. The hydraulic push rod 326 will drive the second slider 323 to slide downwards in the second groove 322 of the connecting plate 321. Since the second slider 323 is hinged with two connecting rods 324, and the other ends of the two connecting rods 324 are respectively hinged to the two first sliders 312 on the slide rail 311, during the movement of the second slider 323, through the transmission action of the connecting rods 324, the two first sliders 312 will synchronously drive the fixed plates 314 on them to move closer to each other. At the same time, the two fixed plates 314 are respectively connected to the positioning plates 315, and the other ends of the two positioning plates 315 are slidably connected to the second slide rod 317 on the rectangular plate 316. This structure makes the fixed plates 314 and the positioning plates 315 more stable when clamping the casting, thereby realizing the rapid clamping and positioning of the casting. After the casting is fixed, if it is necessary to adjust the working angle of the worktable 216, the pin 223 on the limit block 221 can be pulled out to release the limit block 221 and avoid interfering with the rotation of the shaft 214 to drive the rotating block 215 to rotate. Then, the motor 213 is started. The motor 213 will drive the limit block 221 and the rotating block 215 to rotate synchronously through the shaft 214. Since the top of the rotating block 215 is connected to the worktable 216, the worktable 216 and the clamped casting will rotate synchronously with the shaft 214 to adjust the angle. After adjusting to the appropriate processing angle, the pin 223 is reinserted into the limit block 221 and the corresponding pin hole 222. The limit block 221 is locked to prevent the shaft 214 from driving the worktable 216 to shift. This angle adjustment mechanism can flexibly meet the processing requirements of different angles of the casting, effectively improving the applicability and operational flexibility of the device.
