[0022] The following is a description of the preferred embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0023] Embodiment 1: As Figures 1 to 4 shown, a new type of multi-functional fixture for a numerical control machine tool of the present utility model includes a first clamping plate 9 and a second clamping plate 10. A connecting plate is arranged between the first clamping plate 9 and the second clamping plate 10, and the first clamping plate 9, the second clamping plate 10 and the connecting plate are all arranged on the top surface of the support base 2, and the support base 2 is located on the top surface of the machine tool body 1; a square workpiece 11 can be placed on the top surfaces of the first clamping plate 9 and the connecting plate, and then the position of the second clamping plate 10 is adjusted. By the cooperation of the second clamping plate 10 and the first clamping plate 9, the workpiece is fixed. The position of the second clamping plate 10 is adjustable, so as to facilitate the fixation of workpieces of different sizes.

[0024] One side of the top surface of the support base 2 is fixedly installed with a fixed plate 20. A second screw 7 is rotatably connected between the fixed plate 20 and the connecting plate, and the second screw 7 is threadedly connected to the second clamping plate 10. A second motor 8 is installed on the fixed plate 20. One end of the second screw 7 rotatably penetrates and extends to one end of the fixed plate 20 and is fixedly connected to the output end of the second motor 8.

[0025] When the position of the second clamping plate 10 needs to be adjusted, the second motor 8 drives the second screw 7 to rotate. The second motor 8 is a forward and reverse motor. The rotation of the second screw 7 makes the second clamping plate 10 move along the second screw 7, so as to adjust the position of the second clamping plate 10.

[0026] The first clamping plate 9 and the connecting plate are fixedly arranged on the top surface of the support base 2. A slide groove 17 is formed on one side of the top surface of the support base 2, and a slide block 18 is slidably arranged in the slide groove 17. The slide block 18 is fixedly arranged on the bottom surface of the second clamping plate 10. When the second clamping plate 10 moves, the slide block 18 slides in the slide groove 17, which can play a guiding role.

[0027] One side of the machine tool body 1 is fixedly installed with a fixed frame 3. A first screw 4 is rotatably arranged on the fixed frame 3, and the first screw 4 is threadedly connected to the support base 2; a first motor 5 is fixedly installed on the top surface of the fixed frame 3. The top end of the first screw 4 rotatably penetrates and extends to the top surface of the fixed frame 3 and is fixedly connected to the output end of the first motor 5.

[0028] The first motor 5 is a forward and reverse motor. When it works, it can drive the first screw rod 4 to rotate, thereby adjusting the height of the support base 2 to adapt to the processing of workpieces by processing equipment.

[0029] On the other side of the machine tool body 1, a limit plate 16 is fixedly arranged. A guide frame 6 is fixedly arranged on the limit plate 16, and the guide frame 6 is slidably connected to the support base 2; the guide frame 6 is U-shaped, and the distance between the two vertical sections of the guide frame 6 is greater than the width of the second clamping plate 10 to avoid affecting the movement of the second clamping plate 10. When the support base 2 moves, one end of it will move along the guide frame 6, so as to play a guiding role.

[0030] The bottom surface of the support base 2 is symmetrically and fixedly connected with telescopic rods 19; the top surface of the machine tool body 1 is symmetrically provided with installation grooves 21. The telescopic rods 19 are spring telescopic rods 19, that is, a spring (not shown in the figure) is connected between the telescopic end and the fixed end of the telescopic rod 19. The telescopic rods 19 play a certain supporting and connecting role for the support base 2 and contract correspondingly as the support base 2 moves, and the fixed ends of the telescopic rods 19 are fixed in the installation grooves 21.

[0031] Embodiment 2: As Figures 2 to 4 shown, a clamping plate 13 is detachably arranged on the opposite surfaces of the first clamping plate 9 and the second clamping plate 10; mounting plates 15 are respectively installed on the opposite surfaces of the first clamping plate 9 and the second clamping plate 10 through fastening bolts. Connecting rods 14 are fixedly connected to the opposite surfaces of the mounting plates 15, and the clamping plate 13 is fixedly connected to the opposite surfaces of the connecting rods 14. When it is necessary to clamp and fix the circular workpiece 12, the clamping plate 13 can be installed on the first clamping plate 9 and the second clamping plate 10 through the mounting plates 15, so as to realize the clamping of the circular workpiece 12.

[0032] During work, the first clamping plate 9 and the second clamping plate 10 can clamp and limit the square workpiece 11. By installing the clamping plate 13 on the first clamping plate 9 and the second clamping plate 10, the circular workpiece 12 can be clamped and limited, improving the applicability. Moreover, the position of the second clamping plate 10 is adjustable, so as to facilitate the clamping of workpieces of different sizes. And the height of the support base 2 can be adjusted by the first screw rod 4 to facilitate the processing of workpieces.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
