Description

A clamping mechanism of a blank turning machine that uses a rotating cylinder to realize blank turning in the air

technical field

The utility model relates to the technical field of blank turning machines, in particular to a clamping mechanism of a blank turning machine which utilizes a rotating cylinder to realize blank turning in the air, and is used for clamping and turning over adobes in the air.

Background technique

In the existing turning machine, in order to realize the turning of the bricks in the air, the technical means adopted are: install the motor, sprocket and hinge on the gripper, the chuck and the rotating wheel are designed together, and the chuck and the lower end of the gripper rotate connect. After the chuck clamps the brick, start the motor to drive the sprocket to rotate, and the hinge drives the rotating wheel to rotate, thereby driving the chuck to rotate to realize the blank turning in the air.

In the actual use process, it is found that such a structure is very complicated, the configuration cost is high, and it is unnecessary, and a simpler method can be used to realize the flipping in the air.

Utility model content

The purpose of the invention of the utility model is to provide a clamping mechanism of a billet turning machine which uses a rotating cylinder to realize the billet turning in the air, and has a simpler structure.

The technical scheme that the utility model adopts is such:

A clamping mechanism of a blank turning machine that uses a rotating cylinder to realize blank turning in the air, including a connecting frame, a blank clamping cylinder, grippers, chucks and a rotating cylinder. Guide rails are horizontally arranged under the connecting frame, and the upper parts of each gripper are connected in a sliding manner. The top of the gripper on the guide rail and in the middle is fixedly connected with the connecting frame, the lower part of each gripper is rotated to connect the chuck respectively, and the output ends of the two clamping cylinders are respectively connected to a pull rod, and the pull rod passes through each The gripper is fixedly connected to the end with the gripper in the middle, the upper end of the rotary cylinder is hinged with the gripper, and the lower end is hinged with the chuck.

As a preference, the chucks at the lower part of each gripper are divided into passive chucks and active chucks arranged at intervals, the rotating cylinder is hinged between the active chuck and the corresponding gripper, and there is no gap between the passive chuck and the corresponding gripper. Set up the rotary cylinder. In this preferred solution, one rotating cylinder can simultaneously drive the bricks on both sides, which can effectively reduce the number of rotating cylinders and make the structure simpler.

Preferably, except for the two outermost chucks, the other chucks all have two clamping surfaces, and the two clamping surfaces are connected by a rotating shaft, and the lower part of the gripper is connected to the rotating shaft in rotation. The position between the two clamping surfaces is relatively fixed.

Preferably, the active chuck is square, and the lower end of the rotary cylinder is hinged on one corner of the chuck. This preferred solution can utilize the rotary cylinder to rotate the chuck by ninety degrees.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: the rotary cylinder uniformly drives each adobe to turn over in the air, the structure is simple, and the equipment configuration cost is low.
