[0002] Clamping clamps are commonly used in mechanical manufacturing processes to fix or grip workpieces. In the prior art, clamping clamps typically include two clamping elements arranged opposite each other and a drive mechanism. The clamping clamp uses the drive mechanism to cause the two clamping elements to move relative to each other, thereby clamping the workpiece.

[0003] For example, Chinese patent CN220575264U discloses a centering clamping mechanism, including two clamping modules arranged opposite each other, which clamp the workpiece; and a drive module connected to the two clamping modules, which drives the two clamping modules to close or separate, so that the clamping mechanism can adapt to workpieces of different shapes and sizes. However, the above-mentioned centering clamping mechanism may have the following problems: since the drive module can only drive the two clamping modules to move relative to or away from each other in a straight line, the clamping modules cannot further adjust their angles, making it difficult for the centering clamping mechanism to fit the tapered workpiece, resulting in poor clamping effect on tapered workpieces.

[0004] In view of this, the present invention proposes a clamping clamp adapted to workpieces with tapered shape to solve the above problems. Utility Model Content

[0024] Referring to Figures 1 to 3 , an embodiment of the utility model is proposed, which is a clamping clamp suitable for workpieces with taper:

[0025] A clamping clamp suitable for workpieces with taper comprises two clamping modules 1 arranged oppositely. The clamping module 1 comprises a fixing member 2, a swing member 3 and a clamping member 4 in sequence along the X-axis direction. One end of the swing member 3 is fixedly connected with the clamping member 4, and the other end of the swing member 3 is provided with a hinged protrusion 31 and a swing recess 32 located on both sides of the hinged protrusion 31 along the Y-axis direction. One end of the fixing member 2 is provided with a hinged recess 21 and a swing protrusion 22 located on both sides of the hinged recess 21 along the Y-axis direction. The hinged protrusion 31 is hinged with the fixing member 2 in the hinged recess 21, and the swing protrusion 22 is arranged in the swing recess 32. There is an angle adjustment gap 33 between the swing protrusion 22 and the swing recess 32, the hinged protrusion 31 can rotate around the Y-axis within the angle adjustment gap 33, and because the clamping member 4 is fixedly connected with the swing member 3, the swing member 3 can drive the clamping member 4 to rotate around the Y-axis within the angle adjustment gap 33. The angle adjustment gap 33 is provided with an elastic component.

[0026] During the process of fixing or grabbing the workpiece with taper by the clamping clamp, the two clamping modules 1 move relatively, the clamping member 4 contacts the workpiece, and the clamping member 4 can automatically rotate around the Y-axis according to the taper of the workpiece, so that the clamping member 4 is attached to the surface of the workpiece, thereby improving the clamping effect of the clamping clamp on the workpiece with taper. Moreover, the clamping member 4 is self-adaptive to the taper of the workpiece, so that the clamping clamp can clamp workpieces with different tapers, thereby improving the applicability of the clamping clamp. At the same time, during the process of pressing the workpiece by the clamping member 4, the elastic component is pressed by the swing member 3, so that the elastic component generates a restoring force towards the workpiece, and the clamping member 4 can further clamp the workpiece under the action of the restoring force.

[0029] Along the Z axis direction, the distance between the swing protrusion 22 and the swing member 3 gradually increases from the center to the upper and lower ends, forming the angle adjustment gap 33. The swing protrusion 22 is symmetrically provided with two spring plungers 5 along the Y axis direction. When the diameter of the workpiece gradually increases along the vertical direction upwards, the gripping member 4 rotates around the Y axis upwards to attach to the surface of the workpiece. When the diameter of the workpiece gradually increases along the vertical direction downwards, the gripping member 4 rotates around the Y axis downwards to attach to the surface of the workpiece.

[0030] The gripping clamp further comprises a rotating shaft 6, one end of the rotating shaft 6 is provided with a clamping head 61, the rotating shaft 6 penetrates the swing protrusion 22 and the hinged protrusion 31 along the Y axis direction, the clamping head 61 does not penetrate the swing protrusion 22, and the other end of the rotating shaft 6 is fixedly connected with the swing protrusion 22 through a fastening member 62. When the gripping clamp needs to clamp workpieces with large diameter difference, different sizes of gripping members 4 can be replaced to adapt to workpieces of different sizes.

[0031] The gripping clamp further comprises a driving module for moving the clamping module 1 along the X axis direction. The fixed member 2 is provided with a connecting portion 23 for transmission connection with the driving module at the end away from the swing member 3.
