[0032] The utility model provides a composite clamping device, such as Figures 1 to 3 As shown, it includes a clamping seat 10, a first clamping member 20 and a second clamping member 30. The clamping seat 10 is provided with a clamping cavity 11 and a workpiece placement port 12. The workpiece placement port 12 is connected to the clamping cavity 11. The inner wall of the clamping cavity 11 is formed with a first clamping surface 111 and a second clamping surface 112 adjacent to the first clamping surface 111; the first clamping member 20 is slidably connected to the clamping seat 10 and is opposite to the first clamping surface 111, and is used to clamp the workpiece with the first clamping surface 111 by sliding in the direction of the first clamping surface 111; the second clamping member 30 is slidably connected to the clamping seat 10 and is opposite to the second clamping surface 112, and is used to clamp the workpiece with the second clamping surface 112 by sliding in the direction of the second clamping surface 112.

[0033] Specifically, by setting a clamping seat 10, a first clamping member 20 and a second clamping member 30, the clamping seat 10 is provided with a clamping cavity 11 and a workpiece placement port 12, the workpiece placement port 12 is connected to the clamping cavity 11, and the workpiece to be processed can be placed in the clamping cavity 11 through the workpiece placement port 12, and the inner wall of the clamping cavity 11 is formed with a first clamping surface 111 and a second clamping surface 112 adjacent to the first clamping surface 111, the first clamping member 20 is slidably connected to the clamping seat 10 and is opposite to the first clamping surface 111, and the second clamping member 30 is slidably connected to the clamping seat 10 and is opposite to the second clamping surface 112, and when the workpiece is being processed, During clamping, the first clamping member 20 slides toward the first clamping surface 111, driving the workpiece to abut against the first clamping surface 111, thereby clamping the workpiece in one direction; the second clamping member 30 slides toward the second clamping surface 112, driving the workpiece to abut against the second clamping surface 112, thereby clamping the workpiece in another direction, thereby stabilizing the workpiece. Since the first clamping member 20 and the second clamping member 30 are both slidably connected to the clamping seat 10, the adaptability of the clamping device can be improved, and the workpieces of different shapes and sizes can be clamped by sliding the corresponding distance according to the shapes and sizes of the workpieces.

[0034] It can be understood that the clamping seat 10 can be any seat structure that can be fixed on a machine tool.

[0035] In one embodiment, Figures 1 to 3 As shown, the workpiece placement opening 12 is located at the front and rear sides of the clamping seat 10 , the first clamping surface 111 is located at the side wall of the clamping cavity 11 , and the second clamping surface 112 is located at the top wall of the clamping cavity 11 .

[0036] In one embodiment, Figures 1 to 3 As shown, the first clamping member 20 is a rod, and the first clamping member 20 is slidably connected to the clamping seat 10 along the width direction of the clamping seat 10. The first clamping member 20 is inserted into the insertion hole of the workpiece, and while clamping the workpiece with the first clamping surface 111, it is inserted into the workpiece to limit the front and rear sides of the workpiece.

[0037] In one embodiment, Figures 1 to 3 As shown, the second clamping member 30 includes a rod body 31 and a clamping body 32, the rod body 31 is slidably connected to the clamping seat 10 along the height direction of the clamping seat 10, one side of the clamping body 32 is connected to the rod body 31, and the other side of the clamping body 32 extends to the clamping cavity 11. Specifically, the rod body 31 slides along the height direction of the clamping seat 10, thereby driving the clamping body 32 to move toward the second clamping surface 112, so that the clamping body 32 cooperates with the second clamping surface 112 to clamp the workpiece.

[0038] In one embodiment, Figures 1 to 3 As shown, a limiting protrusion 321 is provided on one side of the clamping body 32 close to the clamping cavity 11, and the limiting protrusion 321 is used to connect the workpiece. Specifically, the clamping body 32 is located on the second clamping surface 112 to cooperate with the workpiece to clamp the workpiece, and can also connect the workpiece through the limiting protrusion 321 to limit the movement of the workpiece and achieve stability of the workpiece.

[0039] In one embodiment, Figure 3 As shown, the clamping seat 10 is provided with a rotation chamber 13, the clamping body 32 is rotatably connected to the rotation chamber 13, the end of the rod body 31 close to the clamping body 32 is provided with a first arcuate abutting surface 311, and the end of the clamping body 32 close to the rod body 31 is provided with a second arcuate abutting surface 322, and the second arcuate abutting surface 322 abuts against the first arcuate abutting surface 311. Specifically, through the rotational connection between the clamping body 32 and the side wall of the rotation chamber 13, and the abutting arrangement of the first arcuate abutting surface 311 and the second arcuate abutting surface 322, when the rod body 31 drives the clamping body 32 to move toward the workpiece, the clamping body 32 can rotate according to the shape of the workpiece, so as to adapt to the limiting of workpieces of different shapes.

[0040] In one embodiment, Figure 3 As shown, the supply rotation chamber 13 is provided with a supply rotation shaft 131, and the clamping member is provided with a supply rotation straight groove 323, and the clamping member is sleeved on the supply rotation shaft 131 through the supply rotation straight groove 323. Specifically, through the provision of the supply rotation shaft 131 and the supply rotation straight groove 323, the clamping member can slide along the side wall of the supply rotation chamber 13 in the height reverse direction while being able to rotate around the supply rotation shaft 131.

[0041] In one embodiment, Figure 3As shown, the interior of the clamping seat 10 is provided with a sliding cavity 14, which extends in the height direction of the clamping seat 10, and the rod body 31 is slidably connected to the sliding cavity 14. Specifically, the sliding cavity 14 can ensure the stable sliding of the rod body 31 along the height direction of the clamping seat 10.

[0042] In one embodiment, Figure 1 and 3 As shown, the composite clamping device further includes a driving unit 40, which includes a first driving member 41, which is hinged to the clamping seat 10, one end of which extends toward the first clamping member 20 and is connected to the first driving member 41, and the first driving member 41 can drive the first clamping member 20 to slide by rotating. Specifically, while the first clamping member 20 is clamping the workpiece, the first driving member 41 can be rotated to drive the first clamping member 20 to move toward the workpiece, thereby clamping the workpiece.

[0043] In one embodiment, the first clamping member 20 is threadedly connected to the first driving member 41. Specifically, through the threaded connection between the first clamping member 20 and the first driving member 41, the length of the first clamping member 20 extending into the clamping cavity 11 can be adjusted by rotation, and then the first clamping member 20 can be adjusted according to workpieces of different sizes to adapt to the clamping of workpieces of different sizes.

[0044] In one embodiment, Figure 1 and 3 As shown, the driving unit 40 further includes a second driving member 42, which is slidably connected to the clamping seat 10, and the two ends of the second driving member 42 are respectively connected to the second clamping member 30 and the first driving member 41, and is used to drive the second clamping member 30 to slide through the rotation of the first driving member 41. Specifically, through the above structure, the first driving member 41 can also drive the second driving member 42 to slide along the clamping seat 10 during the process of rotating around the clamping seat 10, so that the second driving member 42 drives the second clamping member 30 to clamp the workpiece. Therefore, by only controlling the rotation of the first driving member 41, the synchronous driving of the first clamping member 20 and the second clamping member 30 can be achieved, which provides convenience for the clamping of the workpiece.

[0045] In one embodiment, Figure 3As shown, the second driving member 42 is provided with a first wedge surface 33 at one end close to the second clamping member 30, and the second driving member 42 is provided with a second wedge surface 421 abutting against the first wedge surface 33 at one end close to the second clamping member 30. The first wedge surface 33 can drive the second clamping member 30 to slide through the sliding of the second driving member 42. Specifically, the first driving member 41 and the second driving member 42 can convert the sliding of the first driving member 41 along the width direction of the clamping seat 10 into the sliding of the second clamping member 30 along the height direction of the clamping seat 10 through the abutment of the first wedge surface 33 and the second wedge surface 421. And through this arrangement, when the second clamping member 30 is subjected to the downward pressure of the workpiece, the second clamping member 30 generates an axial force acting on the second clamping member 30, so that the first driving member 41 generates a driving force for rotation, and the first driving member 41 generates a force acting on the first clamping member 20 in the direction of the workpiece, driving the first clamping member 20 to be tightly combined with the workpiece, thereby ensuring the stability of the workpiece.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
