Description

Technical Field

[0001] This utility model belongs to the field of grippers, and specifically relates to a gripper mechanism. Background Technology

[0002] Pneumatic grippers are a type of pneumatic component and a key part of modern mechanical equipment. They automate the gripping process, replacing manual labor. In existing gripper devices, multiple grippers are arranged side-by-side to improve gripping efficiency. However, in these devices, the distance between the grippers is fixed. When gripping materials, the distance between the materials and the grippers must be the same. This means that if the distance between the materials and the grippers differs, the gripper distance needs to be adjusted, wasting time and increasing labor costs.

[0003] For example, a prior patent application (application number 201420740994.6) discloses a gripper and a device for picking up and placing annular workpieces. The gripper includes a wedge and a picking / placing section; the picking / placing section includes two clamping teeth, a support, two rotating shafts, and a tension spring; the two clamping teeth are respectively fixed to the support via the two rotating shafts; the two ends of the tension spring are respectively fixed to one end of each of the two clamping teeth; the wedge is clamped between the two clamping teeth, used to allow the other ends of the two clamping teeth to pick up and place the annular workpiece by opening or closing. The gripper disclosed in this prior patent suffers from the aforementioned defects of the prior art. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a gripper mechanism that can grip materials with different spacings, thus offering greater applicability.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A gripper mechanism includes a connector, a gripper body, and a plurality of gripper assemblies. The connector is fixed to the gripper body, and a plurality of supports surround the sides of the gripper body. The plurality of gripper assemblies are respectively disposed on the plurality of supports to surround the connector.

[0007] In this gripper mechanism, an external drive structure can drive the gripper mechanism through a connecting body to rotate the gripper body, and then grip the material through multiple gripper assemblies surrounding the side of the gripper body in sequence. This can meet the gripping needs of materials with different spacing and has better applicability.

[0008] Furthermore, the connecting body is located along the axial direction of the gripper body and is perpendicular to the gripper body.

[0009] Further, the support body is provided with an inclined surface inclined relative to the axial direction of the support body at one end away from the jaw body, and the jaw assembly is arranged on the inclined surface. The arrangement of the inclined surface can avoid interference of other jaw bodies with the insertion of the material piece when the jaw assembly needs to insert the material piece to be gripped into the installation position.

[0010] Further, the jaw assembly comprises a connecting seat and a jaw cylinder, one side of the connecting seat is fixed at the inclined surface, one side of the jaw cylinder is arranged at the other side of the connecting seat, and a clamping opening for clamping the material piece is arranged at the other side of the jaw cylinder.

[0011] Further, the other side of the connecting seat is provided with a sliding rail and sliding block structure, the jaw cylinder is movably arranged on the sliding rail and sliding block structure, and the end of the connecting seat is further provided with an abutting piece, and a pressure sensor is arranged between the abutting piece and the jaw cylinder. When the material piece clamped on the jaw cylinder is inserted into the installation position, whether the material piece is inserted is obtained through the pressure sensor, so as to avoid damage to the material piece.

[0012] Further, the clamping opening is provided with a anti-disengagement part on both sides for preventing the material piece from disengaging.

[0013] Further, the jaw mechanism further comprises a multi-axis mechanical arm, and one end of the connecting body away from the jaw body is connected with the multi-axis mechanical arm. The arrangement of the multi-axis mechanical arm enables the jaw mechanism to integrate the driving structure.

[0014] The beneficial effect of the utility model lies in that in the jaw mechanism, the external driving structure can drive the jaw mechanism through the connecting body to rotate the jaw body, and then sequentially clamps the material piece through the plurality of jaw assemblies around the side edge of the jaw body, so that the jaw mechanism can meet the grasping of material pieces with different distances and has better applicability.
