Detailed Description
Referring to fig. 1 to 3, the present invention provides a workpiece fixture for numerical control machining, including a fixed platform 1, a plurality of rotating rods 2 and a driving element, wherein:
the fixed station 1 is horizontally arranged, a plurality of rotating shafts 3 are fixed on the top surface of the fixed station 1, and the plurality of rotating shafts 3 are distributed in a circumferential mode. The fixed table 1 is provided with a plurality of arc-shaped grooves 6 penetrating through the upper surface and the lower surface of the fixed table, the arc-shaped grooves 6 are distributed in a circumferential manner, the circumference where the arc-shaped grooves 6 are located and the circumference where the rotating shafts 3 are located are concentrically arranged, the arc-shaped grooves 6 are located outside the rotating shafts 3, and the arc-shaped openings of the arc-shaped grooves 6 face the circle center of the circumference where the arc-shaped grooves 6 are located.
A plurality of 2 one ends of rotary rod are articulated and a plurality of 2 other ends of rotary rod all rotate with a plurality of rotation axes 3 respectively and install spacing ball 4, and spacing ball 4 has elasticity, and rotary rod 2 is arc and a plurality of rotary rod 2's arc opening orientation the same.
The driving member is used for driving the plurality of rotating rods 2 to rotate, and comprises a rotating table 5 and a driving motor. The revolving stage 5 is located 1 below of fixed station, be fixed with a plurality of dwang 7 that are the circumference and distribute on the revolving stage 5, a plurality ofly stretch into respectively in a plurality of arc walls 6 and a plurality of dwang 7 can make a round trip to rotate respectively in a plurality of arc walls 6, a plurality of dwang 7 respectively with a plurality of rotary rod 2 be connected and a plurality of dwang 7 can slide respectively on a plurality of rotary rod 2, specifically, the arc outside of rotary rod 2 is equipped with spout 8, sliding connection has slider 9 in the spout 8, slider 9 and dwang 7 fixed connection. The driving motor is used for driving the rotating table 5 to rotate.
