The side of the moving chuck close to the fixed chuck is also provided with an arc-shaped groove matching the workpiece. The drive cylinder with the protruding end facing upward is fixed on the frame. A rack is fixed on the protruding end of the drive cylinder, a gear matching the rack is fixed on the rotating shaft, and the gear is meshed with the rack.

In order to facilitate the positioning of the frame after turning over 180°, further, the outer periphery of the rotating shaft is fixed with a limit rod, and both ends of the limit rod are screwed with a screw, and the rotating shaft is located between the two screws at the two ends of the limit rod. In between, a limit block is arranged below the rotating shaft on the frame.

Further, the rack is a cylindrical rack.

Further, a box body is fixed on the outside of the frame, the gear is located in the box body, a guide sleeve is fixed on the box body, and a guide cavity matching the rack is provided in the guide sleeve. The rack is slidably arranged in the guide cavity, and the service life of the rack can be improved through the cooperation of the guide sleeve and the rack, preventing the rack from being subject to a large lateral load.

Further, a proximity switch is fixed at the end of the guide sleeve away from the rack.

The beneficial effects of the utility model are: the disc-shaped workpiece turning mechanism of the utility model drives the moving chuck to move closer to the fixed chuck through the clamping cylinder to clamp the disc-shaped workpiece on the frame, and then drives the gear through the jacking cylinder. The bar moves along a straight line, and the rack drives the gear to rotate, so as to realize the 180° flip of the frame and the workpiece. The utility model has the advantages of simple structure, convenient operation, time saving and labor saving, and greatly improves the production efficiency.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These accompanying drawings are all simplified schematic diagrams, and only illustrate the basic structure of the utility model in a schematic way, so it only shows the composition, direction and reference (for example, up, down, left, right, etc.) related to the utility model May only be used to aid in the description of features in the drawings. Accordingly, the following Detailed Description is not to be taken in a limiting sense, and the scope of claimed subject matter should be defined only by the appended claims and their equivalents.

Example 1

As shown in Figure 1-5, a disc-shaped workpiece turning mechanism includes a frame 1 and a frame 2. The frame 2 is installed on the frame 1 through a rotating shaft 8, and a fixed chuck 3 is fixed on one side of the frame 2. The other side is provided with the clamping cylinder 5 with the protruding end facing the fixed chuck 3, the protruding end of the clamping cylinder 5 is fixed with the movable chuck 4, and the side of the fixed chuck 3 close to the movable chuck 4 is provided with a The arc-shaped groove 6 that matches the workpiece, the side of the movable chuck 4 close to the fixed chuck 3 is also provided with an arc-shaped groove 6 that matches the workpiece, and the drive cylinder 7 with the protruding end facing upward is fixed on the frame 1. A rack 12 is fixed on the protruding end of the driving cylinder 7 , and a gear 13 matched with the rack 12 is fixed on the rotating shaft 8 , and the gear 13 is meshed with the rack 12 .

The outer circumference of the rotating shaft 8 is fixed with a limit rod 9, and the two ends of the limit rod 9 are screwed with a screw 10, the rotating shaft 8 is located between the two screws 10 at the two ends of the limit rod 9, and the frame 1 is arranged below the rotating shaft 8 Limited block 11.

The rack 12 is a cylindrical rack.
