Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for machining centers. Background Technology

[0002] In the modern machining industry, machining centers evolved from CNC milling machines. A machining center is a CNC machine tool that integrates multiple functions such as milling, drilling, and tapping. During the machining process, a vise is needed to fix the workpiece to ensure the machining accuracy of the workpiece.

[0003] However, existing flat-jaw vises are relatively difficult to clamp round and thin workpieces. During machining in a machining center, the workpiece may fly out or shift, resulting in insufficient machining accuracy or even becoming a scrap. This not only increases factory costs but also reduces factory production efficiency. Utility Model Content

The length of the limiting block 404 is equal to the length of placement plate 403. The lengths of the 03 plates are the same. Several placement slots 5 are formed on the placement plate 403. Placement slots 5 are used to place the parts to be processed. One end of each placement slot 5 is arc-shaped. A second placement slot 6 is formed on the limiting block 404 to cooperate with the placement slots 5. One end of the second placement slot 6 is also arc-shaped. Fixing components 406 are installed on the mounting plates 401 and 402. Fixing components 406 are used to fix the placement plate 403 and push the limiting block 404 during lathe processing. The second placement slot 6 on the limiting block 404 is used to clamp the parts in the placement slots 5. The workpiece is clamped by the arc-shaped ends on the first placement groove 5 and the second placement groove 6. A through hole 7 is provided on the first placement groove 5 to discharge the waste chips during processing. A through hole 8 is provided on the first placement groove 5, located on one side of the through hole 7. A semi-circular through hole 9 is provided on the first placement groove 5.

One through hole 4 12 mates with through hole 2 8, and the other through hole 4 12 mates with semi-circular through hole 1 9 and semi-circular through hole 2 10.

[0023] Furthermore, a protrusion 13 is provided on each side of the placement plate 403, and the lower surface of the limiting block 404 slides on the protrusion 13, which makes the movement of the limiting block 404 more stable.

[0024] The fixing assembly 406 includes a first cylinder 14, a second cylinder 15, a first fixing plate 16, a second fixing plate 17, a first pressure block 18, a second pressure block 19, and a top block 20. A second mounting groove is provided on the first mounting plate 401, and the first cylinder 14 is installed in the second mounting groove. The first fixing plate 16 is fixedly connected to the output shaft of the first cylinder 14. Two pressure blocks 18 are fixedly connected to the first fixing plate 16, located between the upper and lower surfaces of the limiting block 404. A second cylinder 15 is provided on each side of the placement plate 403, and the second cylinder 15 is fixedly connected to the second mounting plate 402. A second fixing plate 17 is fixedly connected to the output shaft of the second cylinder 15, and a second pressure block 19 is fixedly attached to the lower surface of the second fixing plate 17. The second pressure block 19 is located above the placement plate 403. Two top blocks 20 are fixedly connected to the front end of the second mounting plate 402. The left end of one top block 20 is flush with the left end of the first mounting groove, and the right end of the other top block 20 is flush with the right end of the first mounting groove. After the placement plate 403 is placed in the first mounting groove, the first cylinder 14 pushes the first fixing plate 16. The first pressure block 18 on the first fixing plate 16 pushes the two limiting blocks 404 on the placement plate 403 to retract. Under the bidirectional pressure of the top block 20 and the first cylinder 14, the two limiting blocks 404 clamp simultaneously, so that the workpiece is fixed in the placement plate 403. Then the second cylinder 15 is activated. When the second pressure block 19 presses on the upper surface of the placement plate 403, the placement plate 403 can be fixed more stably.

[0025] In one embodiment, the limiting component 405 is a fixed rod 21, and a plurality of fixed rods 21 are fixedly connected to both sides of the placement plate 403, and the limiting block 404 slides on the fixed rods 21.

[0026] In another embodiment, the limiting component 405 includes a positioning rod 22, a positioning plate 23, and a spring 24. Several positioning rods 22 are fixedly connected to both sides of the placement plate 403. One end of the positioning rod 22 is fixedly connected to the placement plate 403, and the other end of the positioning rod 22 is fixedly connected to the positioning plate 23. A spring 24 is installed between the placement plate 403 and the positioning plate 23. The spring 24 is sleeved on the positioning rod 22. One end of the spring 24 is fixedly connected to the placement plate 403, and the other end of the spring 24 is fixedly connected to the positioning rod 22. When the processing is completed, the cylinder 14 will drive the pressure block 18 to retract, and under the action of the spring 24, the limiting block 404 will quickly spring back and release the clamped workpiece.

[0027] Working principle of the utility model: The workpiece to be processed is placed in the first placement slot 5 on the placement plate 403 in sequence. The fixing device will push the limiting block 404, and the second placement slot 6 on the limiting block 404 will cooperate with the first placement slot 5 on the placement plate 403. The arc end on the first placement slot 5 and the arc end on the second placement slot 6 will firmly fix the round workpiece, thereby solving the problem that existing flat-jaw pliers are relatively difficult to clamp round and thin workpieces.
