[0011] Preferably, a T-slot is provided at one end of the turntable, and a locking block is provided at the lower end of the first movable plate, and the surface of the locking block is in contact with the surface of the T-slot. Through the coordinated use of the T-slot and the locking block, when the locking block moves inside the T-slot, a stable moving position can be maintained.

[0012] Preferably, a handle is provided at one end of the ball screw, and when the device is in use, the staff can turn the handle, making the device more convenient to operate.

[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The mechanical engineering involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 3As shown, this embodiment proposes a clamping device for processing cylindrical metal workpieces, including a chassis 1, an anti-slip pad 2 is fixed to the upper end of the chassis 1, a rotating block 3 is slidably engaged at the middle position of the chassis 1, and a turntable 4 is fixed to the upper end of the rotating block 3, one end of the turntable 4 is connected to a ball screw 5 by a bearing, and the other end of the turntable 4 is threadedly connected to a bolt 6, a support column is provided at the lower end of the chassis 1, and the support column is provided in multiple groups, and the surface of the lower end of the bolt 6 is in contact with the surface of the upper end of the anti-slip pad 2,

[0026] In this embodiment, by using the rotating block 3 and the turntable 4 in combination, when the turntable 4 is rotated, the metal workpiece can be driven to rotate, thereby adjusting the appropriate orientation to process the metal workpiece according to the needs of the staff. By using the anti-slip pad 2 and the turntable 4 in combination, when the surface of the lower end of the bolt 6 fits with the surface of the upper end of the anti-slip pad 2, the position of the turntable 4 can be fixed, which improves the convenience of the equipment to a certain extent.

[0027] Example 2

[0028] like Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: the surface of the ball screw 5 is threadedly connected to the first movable plate 7, and one end of the first movable plate 7 is hingedly connected to the first clamping plate 8, the upper end of one end of the first movable plate 7 is hingedly connected to the second movable plate 9, and one end of the second movable plate 9 is hingedly connected to the second clamping plate 10, one end of the turntable 4 is provided with a T-slot, the lower end of the first movable plate 7 is provided with a locking block, and the surface of the locking block fits the surface of the T-slot, one end of the ball screw 5 is provided with a turning handle, locking grooves are provided on both sides of the turntable 4, and the lower end of one end of the first movable plate 7 and the lower end of one end of the second movable plate 9 are both provided with locking blocks, and the surface of the locking groove is adapted to the surface of the locking block, one side of the locking groove on both sides of the turntable 4 is provided with a T-slot, and the lower end of the first clamping plate 8 and the lower end of the second clamping plate 10 are both provided with a T-slot, and the surface of the T-slot fits the surface of the T-block, and the first clamping plate 8 and the second clamping plate 10 are both arc-shaped;

[0029] When the first movable plate 7 and the second movable plate 9 are in contact with each other, the first movable plate 7 and the second movable plate 9 are moved in a forward or backward direction, thereby changing the angle of the first movable plate 7 and the second movable plate 9. At the same time, the first clamping plate 8 and the second clamping plate 10 are moved inward or outward synchronously. When the ball screw 5 and the handle are used in conjunction with each other, when the handle is turned, the ball screw 5 is rotated, thereby driving the first movable plate 7 to move forward or backward, which improves the convenience of the device to a certain extent. The engaging block provided at the lower end of the first movable plate 7 and the second movable plate 9 at the contact position of the first movable plate 7 and the second movable plate 9, when the ball screw 5 is rotated, the engaging block can be smoothly moved inside the turntable 4 through the engaging block, which improves the convenience to a certain extent. To ensure the stability of the equipment, through the coordinated use of the turntable 4, the first movable plate 7 and the second movable plate 9, when the angle of intersection of the first movable plate 7 and the second movable plate 9 changes, the positions of the first movable plate 7 and the second movable plate 9 can be restricted by the T-blocks arranged at the lower ends of the first movable plate 7 and the second movable plate 9, so that the first movable plate 7 and the second movable plate 9 are more stable when moving. Through the coordinated use of the turntable 4, the first clamping plate 8 and the second clamping plate 10, when the first clamping plate 8 and the second clamping plate 10 move synchronously, the T-blocks arranged at the lower ends of the first clamping plate 8 and the second clamping plate 10 slide inside the turntable 4, thereby clamping the metal workpiece more firmly.

[0030] Working principle: When the equipment is in use, first place the equipment in a suitable position, then rotate the ball screw 5 to move the first movable plate 7 forward or backward, and change the intersection angle of the first movable plate 7 and the second movable plate 9, thereby driving the first clamping plate 8 and the second clamping plate 10 to move inward or outward synchronously. When the inner surface of one side of the first clamping plate 8 and the second clamping plate 10 are close to each other and fit the surface of the metal workpiece, the rotation of the equipment can be stopped at this time. When other parts of the metal workpiece need to be processed, the turntable 4 can be rotated to drive the metal workpiece to rotate. When the staff adjusts to a suitable position, turn the bolt 6 downward to fix the position of the turntable 4. At this time, the metal workpiece can be processed. The above is the entire working principle of this utility model.

[0031] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
