The elastic reset member is disposed between the side of the push block 21 and the inclined block 22 to push the push block 21 up. A lower groove is also provided in the inclined slide groove 221 of a pair of inclined blocks 22, and an upper groove is also provided on the inclined protrusions 211 on both sides of the push block 21. The elastic reset member is a spring and is installed in the upper groove and the lower groove on the same side. The two ends of the spring are respectively against the upper top wall of the upper groove and the lower bottom wall of the lower groove. The elastic reset member can also be a tension spring or a rubber body. The push block 21 can be driven downward by a corresponding screw or a suction nozzle. Multiple suction nozzles are connected to the suction system, and the suction system can act on multiple suction nozzles at the same time, so that the push blocks of multiple OK clips can be driven by the corresponding suction nozzles to achieve synchronous downward movement.

[0032] One or more OK clamps 2 can be selectively arranged on the fixture plate 1, and the fixture plate 1 has workpiece stations 11 on both sides of each OK clamp 2, and also includes a base 3, a machine base 4 and a rocking table 5. The fixture plate 1 can be rotatable around the Z axis and is installed on the rocking table 5 and driven by a first drive group 6. A plurality of fixture plates 1 are arranged on the rocking table 5, and the first drive group 6 can be a plurality of motors that independently drive each fixture plate 1 to rotate, or a motor that drives a plurality of fixture plates 1 to rotate simultaneously through a plurality of gear groups or a transmission pulley group;

[0033] The cradle 5 is rotatable around the X-axis and is mounted on both ends of the base 4 and driven by a second drive group 7. The second drive group 7 can be a motor connected to the cradle 5 through a gear group or a drive belt pulley group.

[0034] The machine base 4 can be slidably arranged on the bottom base 3 along the X-axis and driven by the third driving group 8. The machine base 4 and the base 3 cooperate with each other through the guide rail and guide groove group 9 arranged along the X-axis to realize sliding guidance. The third driving group 8 includes a screw rod, a nut seat and a motor that drives the screw rod to rotate. The nut seat is sleeved on the screw rod and can slide along the X-axis. The base is fixed or integrally mounted on the nut seat.

The transmission shaft 71 has a socket 711 for inserting the connecting column, and a clamping block 721 is integrally arranged on the outer periphery of the connecting column 72. A slide groove 712 is arranged along the axial direction of the inner wall of the socket 711, and the clamping block 721 slides in the slide groove 712. A clamping groove 713 is arranged at the lower end of the slide groove 712, and the clamping groove 713 is staggered with the slide groove 712. When the connecting column 72 is inserted into the socket 711, the clamping block 721 is clamped into the clamping groove 713 at the lower end of the slide groove through the circumferential rotation of the connecting column 72 to form an axial fixation. The bottom wall of the slot 713 has an arc-shaped first locking protrusion 7131, and the lower end of the block 721 has an arc-shaped second locking protrusion 7211. The two locking protrusions cooperate to prevent the block 721 from sliding out of the slot 713. There are multiple slide slots 712 on the circumference of the inner wall of the jack, and there are multiple blocks 721 on the circumference of the connecting column. Of course, the connecting column can also be provided with a socket for inserting the transmission shaft.

The utility model can slide along the X-axis through the machine base 4, and the machining head for machining the workpiece can also move along the Y-axis and the Z-axis to facilitate machining, and can also rotate around the X-axis and the Z-axis, thereby driving the clamped workpiece to rotate freely on the multi-axis, which can be suitable for machining workpieces with relatively complex geometric shapes.

[0038] Furthermore, the rotational engagement of the connecting column 72 and the transmission shaft 71 facilitates the assembly and disassembly of the fixture plate 1, and the assembly and disassembly is quick, and the fixture plate 1 with different fixtures can also be replaced. During installation, the connecting column at the bottom of the fixture plate 1 is inserted downward into the insertion hole 711 of the transmission shaft 71 at the upper end of the cradle 5, and the clamp block 721 slides downward in the slide groove 712. After that, the fixture plate 1 is rotated so that the clamp block 721 can be rotated circumferentially and clamped into the clamp groove 713 at the lower end of the slide groove to form axial fixation, thereby preventing the fixture plate 1 from being separated from the cradle 5.
