[0020] Please refer to Figure 1 - Figure 4 As shown, the utility model provides a fixture for machining mechanical parts, including a fixed base plate 1 and a clamping plate 10. The fixed base plate 1 is provided with symmetrical fixing holes 2 for fixing the device on a machining table. A slide groove 4 is provided inside a slide rail 3. A limiting groove 5 is provided on the inner side wall of the slide rail 3. A movable sliding block 12 is movably provided inside the slide groove 4. A limiting block 13 is formed on the front and rear sides of the sliding block 12. The limiting block 13 extends into the limiting groove 5. The sliding block 12 slides in the slide groove 4, and the limiting block 13 slides in the limiting groove 5 at the same time. The limit groove 5 and the limit block 13 cooperate to make the sliding block 12 move more smoothly. The left and right ends of the slide rail 3 are formed with mounting blocks 7. A second motor 14 is arranged on the left side of the slide rail 3. A bidirectional lead screw 6 is installed on the output shaft of the second motor 14. The bidirectional lead screw 6 extends to the right and passes through the mounting block 7 and the sliding block 12 on the left side, so that the two sliding blocks 12 are close to each other or principle along the bidirectional lead screw 6. The bidirectional lead screw 6 is screwed with the sliding block 12 but not with the mounting block 7. The right end of the sliding block 12 is movably connected to the left side of the mounting block 7 on the right side.

[0021] When clamping and fixing the parts, the second motor 14 is controlled to rotate, and the second motor 14 rotates and engages with the two sliding blocks 12, so that the two sliding blocks 12 are close to each other, and the clamping plates 10 are close to each other to clamp the parts. When the placement state of the parts needs to be changed, the second motor 14 is controlled to rotate in the opposite direction, and the second motor 14 rotates and engages with the two sliding blocks 12, so that the two sliding blocks 12 are away from each other. After adjusting the parts, the second motor 14 is controlled to rotate again, so that the two sliding blocks 12 are close to each other to clamp the parts.

[0022] like Figure 1 - Figure 4 As shown, a slide rail 3 is provided on the upper surface of the fixed base plate 1, and two sliding blocks 12 are movably provided in the slide rail 3 and are symmetrical to each other. A mobile frame 8 is fixedly provided above the two sliding blocks 12, and a mounting hole 15 is provided on the mobile frame 8. A rotatable rotating connection member 9 is installed in the mounting hole 15.

A first motor 11 is installed on the left side of the mobile frame 8 on the left side, and the output shaft of the first motor 11 is connected to the left end of the rotating connection member 9 on the left side. The rotating connection member 9 consists of a transmission shaft and two circular baffles, and the circular baffles are arranged at both ends of the transmission shaft.

[0023] When processing a part, the first motor 11 is controlled to rotate to drive the rotating connecting member 9 connected thereto to rotate, and at the same time drives the part and another rotating connecting member 9 to rotate, so as to realize the rotation and face changing of the part;

[0024] Specific working principle:

[0025] When using the device, the second motor 14 is controlled to rotate. When the second motor 14 rotates, it is screwed with the two sliding blocks 12, so that the two sliding blocks 12 are close to each other, and the clamping plates 10 are close to each other to clamp the parts. The first motor 11 is controlled to rotate to drive the rotating connecting member 9 connected thereto to rotate, and at the same time drive the parts and another rotating connecting member 9 to rotate, so that the parts rotate to change the surface. When the placement state of the parts needs to be changed, the second motor 14 is controlled to rotate in the opposite direction. When the second motor 14 rotates, it is screwed with the two sliding blocks 12, so that the two sliding blocks 12 are away from each other. After adjusting the parts, the second motor 14 is controlled to rotate again, so that the two sliding blocks 12 are close to each other to clamp the parts.
