The utility model discloses a tooling fixture for machine tools that is convenient for taking and placing workpieces. It is mainly used to clamp the workpiece by two groups of symmetrically arranged cylinders and pressing plates in cooperation with the electric cylinder and pressing plates above. After the workpiece is clamped and processed, the pressing plates move away from each other and the workpiece falls on the support. A manual arm needs to be extended into the space formed by the clamping plates to take out the workpiece, which is a scene in which taking and placing the workpiece is relatively troublesome.

With reference to Figures 1, 2 and 3, a fixture for machine tools that is convenient for picking up and placing workpieces comprises a base 1 and a carrying plate 4 arranged above the base 1, a fixed clamp 5 is fixedly arranged on the upper end of the carrying plate 4, a vertical seat 6 is fixedly arranged on the upper end of the carrying plate 4 away from the fixed clamp 5, a threaded rotating rod 7 is internally threadedly connected to the vertical seat 6, and a movable clamp 8 is rotatably connected to one end of the threaded rotating rod 7, and also comprises: a workpiece moving mechanism: the workpiece moving mechanism comprises a through groove 11 opened at the upper end of the carrying plate 4, a supporting frame 12 is fixedly arranged in the through groove 11, a guide member is fixedly arranged on the inner side wall of the supporting frame 12, a push plate 15 is fixedly arranged on one side of the guide member, a movable plate 16 is fixedly arranged on the upper end of the push plate 15, the movable plate 16 is located at the upper end of the carrying plate 4, and a linkage member for transmission is internally threadedly connected to the movable plate 16; an angle adjustment mechanism: the angle adjustment mechanism is arranged between the base 1 and the carrying plate 4, and the angle adjustment mechanism is used to adjust the angle of the workpiece.

In this solution, the linkage rotates following the movement of the movable clamping plate 8, pushing the push plate 15 to move along the support frame 12, driving the movable plate 16 to move, so that the fallen workpiece is pushed out between the fixed clamping plate 5 and the movable clamping plate 8, thereby facilitating the picking and placing of the workpiece. The display surface of the workpiece can be adjusted through the angle adjustment mechanism, thereby facilitating multi-angle processing of the workpiece.

Among them, a T-shaped guide rod 9 is fixedly set on one side of the movable splint 8, and the T-shaped guide rod 9 is slidably connected in the guide plate 10, and the guide plate 10 is fixedly set on the upper end of the supporting plate 4. Through two groups of T-shaped guide rods 9, the suspended movable splint 8 will not rotate at will, and can follow the rotation of the threaded rotating rod 7 to approach or move away from the fixed splint 5.

3 and 4 , in a preferred embodiment, the guide member includes a slide rail 13 fixedly disposed on the inner wall of the support frame 12, a slider 14 is slidably connected to the slide rail 13, the slider 14 is fixedly disposed on one side of the push plate 15, and a set of slide rails 13 and sliders 14 are fixedly disposed on both sides of the interior of the support frame 12, and the length of the slide rail 13 is equal to the internal length of the support frame 12.

Specifically, two groups of sliders 14 and slide rails 13 symmetrically arranged inside the support frame 12 can limit the push plate 15 so that the push plate 15 can stably move forward and backward along the support frame 12 .

1 and 3 , in a preferred embodiment, the linkage member includes a threaded rod 17 threadedly connected to the push plate 15 , one end of the threaded rod 17 is rotatably connected to the inner wall of the support frame 12 , a gear 18 is welded to the other end of the threaded rod 17 , a gear plate 19 is meshedly connected to the lower end of the gear 18 , a special-shaped cantilever 24 is fixedly arranged below the gear plate 19 , and the special-shaped cantilever 24 is fixedly arranged at one end of the T-shaped guide rod 9 .

Furthermore, the special-shaped cantilever 24 moves along with the T-shaped guide rod 9, thereby pushing the toothed plate 19 to move. When the toothed plate 19 moves, it pushes the gear 18 to rotate, thereby pushing the threaded rod 17 to rotate, so that the push plate 15 drives the moving plate 16 to rotate at the same time.

1 , in a preferred embodiment, the angle adjustment mechanism includes a vertical frame 2 fixedly provided at the upper end of a base 1, a vertical plate 3 is rotatably connected inside the vertical frame 2, the vertical plate 3 is fixedly provided at the lower end of a load-bearing plate 4, a power member for driving the angle change is fixedly provided at the lower end of the support frame 12, the power member includes a hollow plate 20 fixedly provided at the lower end of the support frame 12, a through shaft 21 is penetrated and connected inside the hollow plate 20, an L-shaped frame 22 is fixedly provided at one end of the through shaft 21, and a telescopic rod 23 is fixedly provided at the lower end of the L-shaped frame 22.

It is worth noting that the end of the telescopic rod 23 is fixedly set on the upper end of the base 1, and the minimum angle between the telescopic rod 23 and the upper end of the base 1 is 45°. Therefore, when the telescopic rod 23 is extended, the through-shaft 21 can be pushed obliquely upward to move along the hollow plate 20, and then push the supporting plate 4. The supporting plate 4 rotates in the vertical frame 2 through the vertical plate 3 below, thereby changing the overall angle, and then changing the display angle of the workpiece clamped above, so as to facilitate multi-angle processing of the workpiece.

Working principle: When in use, place the workpiece between the fixed clamping plate 5 and the movable clamping plate 8, rotate the threaded rotating rod 7 counterclockwise to push the movable clamping plate 8 close to the fixed clamping plate 5 until the workpiece is clamped. While the movable clamping plate 8 moves, its T-shaped guide rod 9 drives the special-shaped cantilever 24 to move to one side, and the special-shaped cantilever 24 drives the toothed plate 19 to drive the gear 18 to rotate. While the gear 18 rotates, it pushes the movable clamping plate 8 to move forward so that the movable clamping plate 8 is under the workpiece. When the processing is completed, rotate the threaded rotating rod 7 clockwise to move the movable clamping plate 8 away from the fixed clamping plate 5, and the workpiece falls on the movable clamping plate 8. Continue to rotate the threaded rotating rod 7, and its movable clamping plate 8 drives the workpiece to move backward, so that the workpiece is away from the clamping surface, which makes it easier to pick up and put the workpiece.

The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
