[0030] The utility model is further described below in conjunction with embodiments.

[0031] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0032] Example 1

[0033] Please refer to the instruction manual Figure 1-7 , a V-shaped positioning three-side processing combined tooling, comprising a device body 1, on which two sets of parallel first-order processing mechanisms 2 and two sets of parallel second-order processing mechanisms 3 are installed;

The positioning component 21 is connected to the lateral pressing component 22 . Both the positioning component 21 and the lateral pressing component 22 are connected to the equipment body 1 .

[0035] When the utility model is in use, the workpiece is placed on the equipment body 1, and the equipment body 1 drives the positioning component 21 to position and clamp the workpiece, and the lateral clamping component 22 clamps the side of the workpiece. After the workpiece is processed on the positioning component 21, the second-order processing mechanism 3 performs secondary processing. The equipment body 1 is placed on a four-axis turntable, and the positioning component 21 processes multiple planes and side holes through four-axis rotation, which effectively avoids the generation of burrs on the intersection holes. Because the second-order processing mechanism 3 completes the production, the process is more concentrated, ensuring the stability of dimensional processing.

[0038] The pneumatic cylinders 12 are provided with two, the fixture avoidance holes 13 and the electric cylinders 15 are provided with four, and the corner oil cylinders 14 are provided with two.

[0039] The positioning assembly 21 includes a V-shaped positioning seat 211, a positioning hole 212, a fixing seat 213, a connecting shaft 214, a fixing shaft 215, a rotating plate 216 and an upper pressing block 217. The V-shaped positioning seat 211 is fixedly installed on the upper end of the fixture plate 11, and the positioning hole 212 is opened on the outer side wall of the V-shaped positioning seat 211. The fixing seat 213, the connecting shaft 214, the rotating plate 216 and the upper pressing block 217 are each provided with two, and are respectively located at the front and rear ends of the fixing shaft 215.

[0040] Each group of the V-shaped positioning seats 211 and positioning holes 212 is provided with two and arranged in parallel, so as to clamp four workpieces at the same time.

[0041] The fixing seat 213 , the connecting shaft 214 , the fixing shaft 215 , the rotating plate 216 and the upper pressing block 217 are each provided in two groups and are located between the four V-shaped positioning seats 211 .

[0042] The lateral clamping assembly 22 includes a single-acting cylinder 221 and a T-shaped pressure block 222.

The upper half of the T-shaped pressure block 222 is rotatably connected to the side wall of the V-shaped positioning seat 211.

[0043] The single-acting oil cylinder 221 and the T-shaped pressing block 222 are both provided with two and are respectively located on the sides of the two V-shaped positioning seats 211 .

[0047] When the utility model is in use, the workpiece after one processing is placed on the positioning base 31 for positioning, and the angle cylinder 14 drives the double-headed pressing rod 38 to rotate, and the double-headed pressing rod 38 presses and clamps the upper end of the workpiece, offsetting the axial cutting force generated during 180° drilling; then the electric cylinder 15 is started, and the electric cylinder 15 drives the fixed block 34 to move downward, and the fixed block 34 slides downward in the first fixed seat 33, and the fixed block 34 drives the sliding block 35 to slide in the second fixed seat 36, and the sliding block 35 slides to the side away from the fixed block 34 as the fixed block 34 slides downward, thereby pushing the clamping block 37 to clamp the side wall of the workpiece, and the bottom positioning surface of the positioning base 31 reserves a through hole 32 for processing the side hole, and then the three sides are processed through four-axis rotation.
