In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
Referring to fig. 1 to 3, an embodiment of the present invention provides a novel circular cavity machining fixture, including at least three clamping assemblies 100 evenly distributed circumferentially around a center, where the clamping assemblies 100 include an air cylinder push rod 110, a clamping rod 120 installed on the air cylinder push rod 110, and a clamping head 130 hinged to a front end of the clamping rod 120; one end of the clamping head 130 is a vacuum chuck 131, and the other end is a triangular block 132 opposite to the vacuum chuck 131; the vacuum chuck 131 is connected to the vacuum generator 140 through an air pipe.
In this embodiment, the round cavity workpiece is placed in a central position. The chuck 130 is rotated so that the vacuum chuck 131 at one end of the chuck 130 faces the round cavity workpiece. The cylinder push rod 110 drives the clamping rod 120 to move towards the inner side until the vacuum chuck 131 abuts against the outer wall of the round cavity workpiece; the vacuum generator 140 operates to make the vacuum chuck 131 suck the outer wall of the round cavity workpiece, thereby firmly clamping the round cavity workpiece. The circular chamber is clamped from the outer wall thereof by the vacuum chuck 131 of the clamping head 130. The top surface and the inner wall of the round cavity workpiece are conveniently machined.
The gripper head 130 is rotated to convert the vacuum cup 131 into a triangular block 132 at the other end, and the triangular block 132 is vertically upward with respect to the gripper bar 120, with the vacuum cup 131 facing downward perpendicular to the floor. The cylinder pusher 110 pushes the clamping rod 120 to move inward, thereby approaching the plurality of triangular blocks 132. The round cavity workpiece is placed on the clamping bar 120 with the plurality of triangular blocks 132 all in the inner cavity of the round cavity workpiece. The cylinder push rod 110 drives the clamping rod 120 to move outwards until the triangular block 132 abuts against the inner wall of the circular cavity. The round cavity workpiece is held from the inner wall of the round cavity by the triangular block 132. The outer wall of the round cavity is convenient to process. To sum up, can follow outer wall and inner wall through this novel round cavity adds clamping apparatus and with the centre gripping of round cavity work piece, need not multiple anchor clamps in order to save the cost of production instrument to the centre gripping of round cavity.
In another embodiment, the front end of the clamping rod 120 is further provided with two opposite earrings 121 and a micro motor 122; the earring 121 is perpendicular to the clamping bar 120. The clamping head 130 is located between the two earrings 121; the output shaft of the micro motor 122 is mounted on the two ear rings 121 through a bearing and is fixedly connected with the clamping head 130. The clamping head 130 is rotated by the micro motor 122, so that automatic control is realized, and the precise rotation angle is more convenient and can be ensured.
Further, the triangular block 132 is a triangular prism with a right-angled triangle bottom surface; when the triangular block 132 is vertically upward, the rear end surface of the triangular block 132 is perpendicular to the clamping bar 120. When the triangular block 132 is pressed from the inner wall of the round cavity workpiece to the outer side, the round cavity workpiece is more stably clamped
Specifically, there are four clamping assemblies 100. The angle between the two clamping assemblies 100 is 90 degrees. The circular cavity workpiece is clamped from multiple directions, so that the clamping is more stable.
Above, only the preferred embodiment of the present invention has been described, the present invention is not limited to the above embodiment, and the technical effects of the present invention can be achieved by the same means, which all belong to the protection scope of the present invention.
