[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1-4As shown, this embodiment includes a chuck 10; in this embodiment, the chuck 10 is disc-shaped and is used to connect to the spindle of a CNC machine tool.

[0027] The base 20 is fixedly disposed on the side of the chuck 10; in this embodiment, the base 20 is used to support and place the workpiece.

[0028] The connecting block 30 includes a vertical part 31 and a horizontal part 32 connected to the vertical part 31. The lower end of the vertical part 31 is hinged to the side of the chuck 10 via a hinge seat 35, so that the connecting block 30 can rotate on the chuck 10 via the hinge seat 35.

[0029] The upper end of the vertical part 31 extends out to the base 20; in this embodiment, the end of the base 20 facing the chuck 10 is provided with a notch 21 for the vertical part 31 to pass through, and the lateral dimension of the notch 21 is larger than the lateral dimension of the vertical part 31; thereby, the lateral movement of the vertical part 31 is restricted within the notch 21 by the setting of the notch 21.

[0030] The drive member 40 has its output shaft passing through the chuck 10 and fixedly connected to the upper end of the vertical part 31. Thus, the operation of the drive member 40 drives the connecting block 30 to reciprocate within the notch 21, causing the horizontal part 32 of the connecting block 30 to move up and down.

[0031] The output shaft of the drive component 40 is connected to the chuck 10 through the bushing 41; thus, the stable operation of the drive component 40 can be ensured by the bushing 41; in this embodiment, the drive component 40 includes a hydraulic cylinder, a telescopic cylinder, etc.

[0032] The clamping assembly includes a longitudinal fixing rod 50 disposed at one end of the transverse portion 32 away from the vertical portion 21. In this embodiment, the longitudinal fixing rod 50 is perpendicular to the vertical portion 31 and also perpendicular to the transverse portion 32. In addition, it is parallel to the base 20.

[0033] In this embodiment, a longitudinal through hole 33 is provided at the end of the horizontal part 32 away from the vertical part 31, and a longitudinal fixing rod 50 is disposed in the longitudinal through hole 33. The diameter of the longitudinal through hole 33 is larger than the diameter of the longitudinal fixing rod 50. Thus, when the horizontal part 32 of the connecting block 30 moves up and down, it can drive the longitudinal fixing rod 50 in the longitudinal through hole 33 to move up and down.

[0034] The two ends of the longitudinal fixing rod are respectively fixedly connected to a left vertical rod 61 and a right vertical rod 62. The left vertical rod 61 passes through the base 20 and is connected to a left clamping block 63, and the right vertical rod 62 passes through the base 20 and is connected to a right clamping block 64. In this embodiment, the left vertical rod 61 is fixedly connected to the base 20 through a left bushing 71, and the right vertical rod 62 is fixedly connected to the base 20 through a right bushing 72. Thus, by setting the left bushing 71 and the right bushing 72, the left vertical rod 61 and the right vertical rod 62 can be stably raised and lowered within the left bushing 71 and the right bushing 72, respectively.

[0035] The upper part of the left vertical rod 61 is provided with a left external thread, and a left nut 75 connected to the left external thread is provided on the left vertical rod 61; the upper part of the right vertical rod 62 is provided with a right external thread, and a right nut 76 connected to the right external thread is provided on the right vertical rod 62; the left clamping block 63 is sleeved on the left vertical rod 61 and fixed on the left vertical rod 61 by the left nut 75; the right clamping block 64 is sleeved on the right vertical rod 62 and fixed on the right vertical rod 62 by the right nut 76; thus, the left clamping block 63 and the right clamping block 64 can be replaced by removing the left nut 75 and the right nut 76.

[0036] In this embodiment, the left bushing 71 can restrict the position of the left clamping block 63 on the left vertical rod 61; the right bushing 72 can restrict the position of the right clamping block 64 on the right vertical rod 62.

[0037] A left fixing ring 65 is fitted at the lower part of the left vertical rod 61, and a left base fixing ring 67 is fitted at the upper part. A left spring 68 is fitted between the left fixing ring 65 and the left base fixing ring 67 and on the left vertical rod 61. A right fixing ring 66 is fitted at the lower part of the right vertical rod 62, and a right base fixing ring 69 is fitted at the upper part. A right spring 70 is fitted between the right fixing ring 66 and the right base fixing ring 68 and on the right vertical rod 62. In this embodiment, the left fixing ring 65 is fixedly connected to the left vertical rod 61, the right fixing ring 66 is fixedly connected to the right vertical rod 62, the left base fixing ring 67 is fitted on the left vertical rod 61 and fixedly connected to the base 20, and the right base fixing ring 68 is fitted on the right vertical rod 62 and fixedly connected to the base 20.

[0038] Therefore, by setting the left spring 68 and the right spring 70, a tension force can be formed between the longitudinal fixing rod 50 and the base 20.

[0039] In addition, a transverse arc surface 22 is provided between the left clamping block 63 and the right clamping block 64 and on the base 20; thus, through the provision of the transverse arc surface 22, this utility model can process planar workpieces and also process parts with planar and curved surface connections.

[0040] The working principle of this utility model is as follows;

[0041] When the part to be processed needs to be processed, the drive unit 40 retracts, causing the vertical part 31 of the connecting block 30 to move closer to the chuck 10 within the notch 21. At the same time, the horizontal part 32 of the connecting block 30 rises through the hinge seat 35, driving the longitudinal fixing rod 50 to rise. As the longitudinal fixing rod 50 rises, the left vertical rod 61 and the right vertical rod 62 rise synchronously, causing the left clamping block 63 and the right clamping block 64 on the left vertical rod 61 and the right vertical rod 62 to rise. Then, the left clamping block 63 and the right clamping block 64 move away from the base 20 to form a placement area for placing the part to be processed. The part to be processed is then placed in the placement area.

[0042] The drive unit 40 extends again, causing the vertical part of the connecting block 30 to move away from the chuck 10 within the notch 21. At the same time, the horizontal part 32 of the connecting block 30 descends through the hinge seat 35, driving the longitudinal fixing rod 50 to descend. As the longitudinal fixing rod 50 descends, the left vertical rod 61 and the right vertical rod 62 descend synchronously, causing the left clamping block 63 and the right clamping block 64 on the left vertical rod 61 and the right vertical rod 62 to press down and clamp the workpiece to be processed, thus achieving the clamping of the workpiece to be processed.
