DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-3 As shown, a metal special-shaped parts processing fixture includes a support frame 1, on which two sliders 15 are slidably arranged, and a driving mechanism 3 for driving the two sliders 15 to move in relative directions is arranged on the support frame 1, and a fixed plate 2 is arranged above each slider 15, and an arc groove 6 is symmetrically opened on the fixed plate 2, and a clamping block 7 is rotatably arranged in the arc groove 6, and mounting plates 9 are symmetrically arranged at both ends of the clamping block 7, and sliding grooves 8 are symmetrically opened at both ends of the arc groove 6, and the mounting plate 9 is slidably installed inside the sliding groove 8, and a spring 10 is arranged on the mounting plate 9, and the other end of the spring 10 is fixedly installed inside the sliding groove 8.

[0019] In this embodiment, the clamp block 7 is rotatably installed in the arc groove 6, and its two ends are slidably connected to the slide groove 8 through the mounting plate 9, and the clamping force is provided by the spring 10. The anti-slip pad 14 is arranged at the front end of the clamp block 7 to enhance the clamping stability.

[0020] like Figure 1 As shown, the driving mechanism 3 includes a motor and a bidirectional threaded rod 5. The motor is fixedly arranged on one side of the support frame 1. The output end of the motor passes through the interior of the support frame 1 and is connected to one end of the bidirectional threaded rod 5. Threaded holes 13 are arranged on the two sliders 15, and the threaded rod is installed inside the threaded holes 13.

[0021] In this embodiment, the driving mechanism 3 is a combination of a motor and a bidirectional threaded rod 5. The motor is fixed on one side of the support frame 1, and its output end is connected to one end of the bidirectional threaded rod 5. After starting the motor, the bidirectional threaded rod 5 rotates. Since the threaded holes 13 on the two sliders 15 are respectively matched with the two sections of the thread of the bidirectional threaded rod 5, the two sliders 15 move relative to or away from each other along the axial direction of the threaded rod.

[0022] like Figure 1 As shown, a limiting groove 11 is provided at the bottom of the arc groove 6 , a limiting column 12 is provided at the lower end of the clamping block 7 , and the limiting column 12 is rotatably installed inside the limiting groove 11 .

[0023] In this embodiment, the clamp block 7 rotates around the limiting column 12 in the arc groove 6 under the action of the spring 10 to adapt to the contour of the special-shaped part, while ensuring the reliability and stability of the operation of the clamp block 7.

[0024] like Figure 2 As shown, the front end of the clamping block 7 is provided with an anti-slip pad 14 .

[0025] In this embodiment, the anti-skid pad 14 is disposed at the front end of the clamping block 7 to enhance the clamping stability.

[0026] like Figure 3 As shown, the interior of the support frame 1 is symmetrically provided with guide rods 4 along a direction parallel to the bidirectional threaded rod 5 , and two sliders 15 are both slidably connected to the guide rods 4 .

[0027] In this embodiment, the slider 15 is slidably connected to the guide rod 4 to form a precise guiding system, thereby avoiding the clamping position deviation caused by uneven force and ensuring the processing accuracy.

[0028] Working principle: When in use, first place the workpiece between the two fixed plates 2, and start the motor to drive the bidirectional threaded rod 5 to rotate, thereby driving the two sliders 15 and the fixed plate 2 to move in relative directions and contact the workpiece. The clamping block 7 rotates under the elastic action of the spring 10, fits with the workpiece, and clamps the workpiece.
