DETAILED DESCRIPTION

[0022] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0023] Example 1

[0024] A CNC machine tool fixture that is convenient for material replacement, see Figure 1-Figure 5 As shown, it includes a base 1, a motor 2, a connecting rod 3, a guide rod 5, a moving block 6 and a vise 7. The motor 2 is arranged on the base 1 by bolt connection. The connecting rod 3 is arranged on the output shaft of the motor 2 through a coupling. The connecting rod 3 has multiple groups of reverse threads 4. The guide rod 5 is arranged on the base 1 by welding. The base 1 has a slide groove 8. The connecting rod 3 is threaded with multiple moving blocks 6. The multiple moving blocks 6 are evenly spaced on the connecting rod 3. The moving blocks 6 slide on the slide groove 8 and the guide rod 5. The moving block 6 is connected to a vise 7 for clamping the workpiece.

[0025] See also Figure 1 and Figure 2 As shown, a blocking block 17 is also included. A plurality of blocking blocks 17 for limiting the moving block 6 are arranged on the connecting rod 3 by welding, and the plurality of blocking blocks 17 are evenly spaced and distributed on the connecting rod 3 .

[0026] See also Figure 5 As shown, an anti-skid pad 18 is also included. Two anti-skid pads 18 for anti-skid are embedded at the bottom of the base 1. The anti-skid pad 18 is made of rubber. The rubber is sticky and can achieve a good anti-skid effect.

[0027] When the clamp is needed, the staff places the base 1 at a suitable position of the CNC machine tool, and the anti-slip pad 18 increases the friction between the base 1 and the CNC machine tool. Then the staff uses the tool to install the base 1 on the CNC machine tool. When the workpiece needs to be clamped, the staff places the workpiece on the base 1 so that the workpiece is placed between the corresponding two moving blocks 6, and then turns on the motor 2. The output shaft of the motor 2 rotates to drive the connecting rod 3 to rotate, so that the corresponding two moving blocks 6 drive the vise 7 to move inward to clamp the workpiece. After the clamping is completed, the staff turns off the motor 2 and then processes the workpiece. After the workpiece is processed, the staff turns on the motor 2 again, and then controls the output shaft of the motor 2 to reverse, so that the corresponding two moving blocks 6 drive the vise 7 to move outward and disengage from the workpiece. The blocking block 17 plays a limiting role to prevent the corresponding two moving blocks 6 from moving excessively outward. The staff removes the workpiece from the base 1, places a new workpiece on the base 1, and then controls the output shaft of the motor 2 to rotate forward to clamp the workpiece with the vise 7, thereby achieving the purpose of fast material replacement.

[0028] Example 2

[0029] Based on Example 1, see Figure 4 As shown, it also includes a clamping block 10, a knob 9, a pressure plate 11 and an elastic member 12. The clamping block 10 is rotatably arranged on the moving block 6 and the vise 7. The clamping block 10 is clamped with the moving block 6. The clamping block 10 is provided with a knob 9 by welding. The knob 9 increases the contact area between the staff's hand and the clamping block 10, which is convenient for rotating the clamping block 10. The clamping block 10 is provided with a pressure plate 11 by welding. The pressure plate 11 is connected to an elastic member 12 for auxiliary resetting, and the elastic member 12 is in a compressed state.

[0030] When the vise 7 clamps the workpiece, the clamping block 10 reinforces the vise 7 on the moving block 6 to prevent the vise 7 from being separated from the moving block 6 and affecting the clamping effect. When the vise 7 needs to be replaced, the staff holds the knob 9 by hand and rotates the clamping block 10 to disengage the clamping block 10 from the moving block 6, and the elastic member 12 returns to its original state, so that the pressure plate 11 pushes the clamping block 10 to move upward and disengage from the moving block 6 and the vise 7. The staff removes the vise 7 from the moving block 6, docks the new vise 7 onto the moving block 6, and then pushes the clamping block 10 downward to make the pressure plate 11 contact with the moving block 6, and the elastic member 12 is compressed accordingly. The staff rotates the clamping block 10 to a suitable angle to engage with the moving block 6, and reinforces the new vise 7 on the moving block 6, thereby achieving the effect of quickly replacing the vise 7.

[0031] See also Figure 5As shown, it also includes a material guide frame 13, a storage frame 14 and a handle 15. The material guide frame 13 is arranged inside the slide groove 8 by welding. The material guide frame 13 can guide the debris into the storage frame 14. The storage frame 14 for collecting the debris is slidably arranged inside the base 1. The storage frame 14 is provided with a handle 15 by bolt connection. The handle 15 increases the contact area between the staff's hand and the storage frame 14, which is convenient for pulling the storage frame 14.

[0032] See also Figure 5 As shown, a rubber sleeve 16 is also included, and the handle 15 is covered with the rubber sleeve 16 for anti-slip.

[0033] When the workpiece is being processed, the debris will enter the chute 8 and fall along the guide frame 13. The storage frame 14 will catch the fallen debris, thereby facilitating the timely collection of the debris. When a proper amount of debris is loaded into the storage frame 14, the staff will hold the handle 15 and pull the storage frame 14 to the right to pull the storage frame 14 out of the base 1. The rubber sleeve 16 increases the friction between the staff's hand and the handle 15, and then the debris in the storage frame 14 is poured out. After pouring out, the staff will push the storage frame 14 to the right and push it back into the base 1.

[0034] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
