[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-4 As shown, a CNC machined workpiece positioning chuck shown in the figure comprises a base 1 and a clamping mechanism arranged on the top of the base 1, wherein the clamping mechanism comprises a working component and a clamping component;

[0026] The working assembly includes a motor 2. The motor 2 is arranged on the top of the base 1. The top of the motor 2 is fixedly connected to a connecting plate 3. The top of the connecting plate 3 is fixedly connected to a fixing ring 4. One end of the motor 2 is fixedly connected to a rotating disk 5.

[0027] The clamping assembly includes a sliding column 6, the inner wall of the rotating disk 5 is slidably connected to the sliding column 6, the top of the sliding column 6 is fixedly connected to a pushing block 7, and the bottom of the pushing block 7 is slidably connected to a placing plate 8.

[0028] Among them, Figure 3 As shown, the rotating disk 5 is provided with a sliding groove which matches the sliding column 6. The rotating disk 5 and the sliding column 6 form a sliding structure through the motor 2, which is conducive to driving the sliding column 6 to slide in the groove through the rotation of the rotating disk 5.

[0029] Among them, Figure 3 As shown, the placement plate 8 is provided with a sliding groove that matches the sliding column 6. The sliding column 6 forms a sliding structure with the placement plate 8 through the rotating disk 5, which is conducive to keeping the sliding column 6 in the groove of the placement plate 8 and moving in a straight line.

[0030] Among them, Figure 2As shown, the placement plate 8 is provided with a sliding groove that matches the push block 7. The push block 7 forms a sliding structure with the placement plate 8 through the sliding column 6, which is beneficial to ensure the direction of the push block 7 when sliding and prevent deviation.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, the inner wall of the push block 7 is fixedly connected with a hollow column 9, the inner wall of the hollow column 9 is provided with a spring 10, one end of the spring 10 is fixedly connected with a telescopic column 11, and one end of the telescopic column 11 is fixedly connected with a clamping piece 12.

[0033] Among them, Figure 4 As shown, the push block 7 is provided with a groove that matches the hollow column 9, which is beneficial to saving space and reducing the length of the clamping mechanism.

[0034] Among them, Figure 1 As shown, the hollow column 9 is provided with a sliding groove that matches the telescopic column 11. The telescopic column 11 forms a sliding structure with the hollow column 9 through the spring 10 and the clamping piece 12, which is conducive to clamping the material through the clamping piece 12 to drive the telescopic column 11 to retract into the groove of the hollow column 9.

[0035] When in use: first, the motor 2 fixed at the bottom of the connecting plate 3 is operated to drive the rotating disk 5 to rotate, so that the sliding column 6 moves in the sliding groove opened in the rotating disk 5, and also moves in the sliding groove opened in the placement plate 8, and performs linear motion, and connects to drive the push block 7 to slide in the groove of the placement plate 8 and move in the opening direction;

[0036] Finally, the pushing block 7 is driven to move by the sliding column 6, so that the clamping piece 12 clamps the material. Due to the different shapes of the materials, some of the materials are irregular. At this time, the clamping piece 12 touches the material, driving the telescopic column 11 to shrink into the groove of the hollow column 9, relying on the elastic force of the spring 10 to play a supporting role, and stably fix the material on the base.
