[0014] 1. In the utility model, when an operator needs to replace the fixture, by grasping the handle to drive the driving gear to rotate. During the rotation of the driving gear, the driven gear meshed with the driving gear will rotate following the rotation of the driving gear. During the rotation of the driven gear, the insertion rod fixedly installed with the driven gear will rotate, so that the turning plate installed on the surface of the insertion rod can be turned over, and the arc-shaped fixture assembly originally located below the turning plate and the clamping assembly are swapped in position. The arc-shaped fixture assembly is turned over above the frame for the operator to clamp and fix the processed workpiece, achieving the effect of quickly replacing the machine tool fixture.

[0015] 2. In the utility model, through the arranged assembly plate, the effect of inserting and fixing the handle can be achieved. The first bearing installed at the connection between the handle and the assembly plate will rotate following the rotation of the handle during the rotation of the handle, which can make it more labor-saving for the operator to apply pressure to the handle. Moreover, the weight feedback during the meshing rotation of the driving gear and the driven gear to drive the turning plate to turn over is lower, making it more convenient and labor-saving for the turning plate to replace the fixture.

[0016] 3. In the present utility model, through the provided connection holes, the clamping assembly and the arc-shaped fixture assembly can be fixedly installed on the flipping plate.

[0025] Example 1: A CNC machine tool fixture that is easy to replace, such as Figures 1 - 4 As shown, it includes a frame 1 and a flip plate 5 arranged inside the frame 1, a clamping assembly 6 is installed on one side surface of the flip plate 5, and an arc clamp assembly 20 is fixedly installed on one side surface of the flip plate 5. A plug-in rod 17 is inserted into the interior of the frame 1, and a driven gear 16 is fixedly installed on one end of the plug-in rod 17. The driven gear 16 is meshed and connected with the driving gear 15. The CNC lathe fixture proposed in this utility model patent, at the beginning of production, different types of clamps are set on both sides of the flip plate 5 to handle different types of workpiece clamping. When the operator needs to replace the clamp, he can grab the handle 12 with The driving gear 15 rotates, and the driven gear 16 meshing with the driving gear 15 rotates along with the rotation of the driving gear 15. The plug-in rod 17 fixed to the driven gear 16 rotates, thereby causing the flip plate 5 mounted on the surface of the plug-in rod 17 to flip, and the arc-shaped clamp assembly 20 originally located below the flip plate 5 to be swapped with the clamping assembly 6. The arc-shaped clamp assembly 20 is flipped to the top of the frame 1 for the operator to clamp and fix the workpiece, thereby achieving the effect of quickly replacing the machine tool fixture.

[0026] like Figures 1 - 4 The first bearing 14 is fixedly mounted on the bottom surface of the frame 1, and the handle 12 is plugged into the surface of one side of the assembly plate 13. One end of the handle 12 passes through the assembly plate 13 and is fixedly mounted on the driving gear 15. The first bearing 14 is rotatably mounted at the penetration point of the handle 12 and the assembly plate 13, and the second bearing 18 is rotatably mounted at the penetration point of the plug-in rod 17 and the frame 1. The flip plate 5 is fixedly mounted on the surface of the plug-in rod 17, and the clamping component 6 is fixedly mounted on the upper surface of the flip plate 5. The assembly plate 13 is set, which can achieve the effect of plugging and fixing the handle 12. During the rotation of the handle 12, the first bearing 14 installed at the connection point between the handle 12 and the assembly plate 13 will rotate with the rotation of the handle 12, which can make it easier for the operator to apply pressure on the handle 12, and the driving gear 15 is meshed with the driven gear 16 to rotate and drive the flip plate 5 to flip, so that the weight feedback is lower when the flip plate 5 is flipped, making it easier and more labor-saving to replace the fixture.

[0027] As Figures 1 - 4 shown, a plurality of connection holes 22 are formed on one side surface of the clamping assembly 6. The clamping assembly 6 is riveted and connected to the turning plate 5 through the connection holes 22. A slide rail 7 is fixedly installed on the upper surface of the clamping assembly 6. Two fixing blocks 8 are fixedly installed on the upper surface of the clamping assembly 6. A lead screw 9 is inserted into the inside of the fixing block 8. The lead screw 9 penetrates through the fixing block 8. One end of the lead screw 9 penetrating through the fixing block 8 is provided with a clamping plate 10. One end of the clamping plate 10 slides inside the slide rail 7. Through the provided connection holes 22, the clamping assembly 6 and the arc-shaped fixture assembly 20 can be fixedly installed on the turning plate 5. Through the slide rail 7 installed at the upper end of the clamping assembly 6, the clamping plate 10 can slide inside the slide rail 7 during the clamping and fixing process, making it easier and more labor-saving for the operator to clamp and fix the workpiece. Through the fixing block 8, the lead screw 9 can be inserted and fixed. When clamping a conventional workpiece, by rotating the lead screw 9 inside the fixing block 8, the clamping plate 10 is pushed forward. The clamping plate 10 is rotatably installed with the lead screw 9. During the forward movement of the lead screw 9, the clamping plate 10 does not rotate with the lead screw 9, and thus the workpiece is clamped and fixed with the other fixing block 8. The clamping method of the arc-shaped fixture assembly 20 is the same as that of the clamping assembly 6.

[0028] Embodiment 2: A numerically controlled machine tool fixture that is easy to replace. As Figures 1 - 4 shown, two insertion slots 21 are formed inside the frame 1. A support leg 2 is slidably installed inside the insertion slots 21. A plurality of sliding blocks 4 are fixedly installed inside the frame 1. The sliding blocks 4 are slidably installed on one side of the support leg 2. Through the provided insertion slots 21, the support leg 2 can be inserted and fixed. The sliding blocks 4 installed inside the frame 1 can slide inside the support leg 2, which can facilitate the operator to adjust the height of the machine tool processing to reach a height suitable for their own lathe processing, achieving the effect of easy adjustment.

[0029] As Figures 1 - 4 shown, a limiting rod 19 is rotatably installed inside the frame 1. An installation plate 3 is fixedly installed at the lower end of the support leg 2. Through the provided limiting rod 19, the limiting rod 19 supports the turning plate 5. After the workpiece is clamped and fixed on the turning plate 5, by rotating the limiting rod 19 from inside the frame 1 to the lower surface of the turning plate 5, the support and limiting effect on the turning plate 5 can be achieved, preventing the turning plate 5 from turning again and causing position deviation. When the fixture needs to be replaced, the limiting rod 19 is rotated back inside the frame 1 to cancel the support for the turning plate 5, and the fixture replacement effect can be easily achieved. Through the provided installation plate 3, it can be directly installed on the ground through bolts, achieving the effect of fixing the position of the lathe fixture.

[0030] Working principle: In the numerically controlled lathe fixture proposed in this utility model patent, at the beginning of production, different types of fixtures are set on both sides of the turning plate 5 to clamp different types of workpieces. When the operator needs to replace the fixture, by grasping the handle 12 to drive the driving gear 15 to rotate, during the rotation of the driving gear 15, the driven gear 16 meshed with the driving gear 15 will rotate following the rotation of the driving gear 15. During the rotation of the driven gear 16, the insertion rod 17 fixedly installed with the driven gear 16 will rotate, thereby causing the turning plate 5 installed on the surface of the insertion rod 17 to turn, swapping the positions of the arc-shaped fixture assembly 20 originally located below the turning plate 5 and the clamping assembly 6. The arc-shaped fixture assembly 20 turns above the frame 1 for the operator to clamp and fix the processed workpiece, achieving the effect of quickly replacing the machine tool fixture. Through the provided assembly plate 13, it can achieve the effect of inserting and fixing the handle 12. During the rotation of the handle 12, the first bearing 14 installed at the connection between the handle 12 and the assembly plate 13 will rotate following the rotation of the handle 12, enabling the operator to apply pressure to the handle 12 more labor-savingly, and the weight feedback is lower when the driving gear 15 meshes and rotates with the driven gear 16 to drive the turning plate 5 to turn, making it more convenient and labor-saving for the turning plate 5 to replace the fixture. Through the provided connection holes 22, the clamping assembly 6 and the arc-shaped fixture assembly 20 can be fixedly installed on the turning plate 5. Through the slide rail 7 installed at the upper end of the clamping assembly 6, the clamping plate 10 can slide inside the slide rail 7 during the process of clamping and fixing, making it easier and more labor-saving for the operator to clamp and fix the workpiece. Through the fixed block 8, it can achieve the effect of inserting and fixing the lead screw 9. When clamping a conventional workpiece, by rotating the lead screw 9 to rotate inside the fixed block 8, the clamping plate 10 is pushed forward. The clamping plate 10 and the lead screw 9 are rotatably installed. During the forward movement of the lead screw 9, the clamping plate 10 does not rotate following the lead screw 9, thereby achieving the effect of clamping and fixing the workpiece with the fixed block 8 at the other end. The clamping method of the arc-shaped fixture assembly 20 is the same as that of the clamping assembly 6. Through the provided insertion slot 21, it can achieve the effect of inserting and fixing the support leg 2. The sliding block 4 installed inside the frame 1 can slide inside the support leg 2, facilitating the operator to adjust the height of the machine tool processing to reach a height suitable for their own lathe processing, achieving the effect of easy adjustment. By rotating the limit rod 19 from inside the frame 1 to the lower surface of the turning plate 5, it can support and limit the turning plate 5, preventing the turning plate 5 from turning again and causing position deviation. When the fixture needs to be replaced, the limit rod 19 is rotated back inside the frame 1 to cancel the support for the turning plate 5, and the fixture replacement effect can be easily achieved. Through the provided mounting plate 3, it can be directly installed on the ground through bolts, achieving the effect of fixing the position of the lathe fixture.
