Description

Technical Field

[0001] The utility model relates to the technical field of indexing plates, in particular to a continuous feeding structure of a multi-station indexing plate. Background Art

[0002] A multi-station indexing plate is a precision positioning device used in machining, capable of precise rotational indexing between multiple fixed angles. Its design typically allows multiple machining stations to be processed within a single cycle, enabling rapid workpiece switching between stations and improving production efficiency. Through its high-precision indexing control, the indexing plate allows for positioning, machining, or inspection of workpieces at each station, making it suitable for a variety of machining scenarios, including drilling, milling, and assembly. This device is widely used in automated production lines, machining centers, and CNC machine tools, significantly improving work efficiency and machining accuracy.

[0003] Most of the existing multi-station indexing plates lack a loading structure and automatic loading. Workers need to load materials manually, which increases the operation time of each process, affects the overall production rhythm, and reduces production efficiency. Further improvement is needed. For this purpose, a multi-station indexing plate continuous loading structure is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a multi-station indexing plate continuous feeding structure, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A multi-station indexing plate continuous feeding structure comprises a base plate, a indexing plate body is installed on the rear upper end of the base plate, a plurality of pneumatic chucks distributed in a circular array are installed on the upper end of the indexing plate body, a guide rail is installed on the middle upper end of the base plate, a pushing component is installed on the front upper end of the base plate, a first electric cylinder is installed on the right upper end of the base plate, a moving block is movably sleeved on the outer surface of the guide rail, a pushing groove is provided on the left upper end of the moving block, a concave plate is provided on the right upper end of the moving block, a baffle is provided on the left end of the concave plate, a bracket is installed on the right end of the concave plate, and the bracket is installed on the base plate.

[0007] Preferably, the pushing component includes a second electric cylinder, the second electric cylinder is mounted on the base plate, and the output end of the second electric cylinder is fixedly connected to a push rod.

[0008] Preferably, the output end of the first electric cylinder is fixedly connected to the right end of the moving block.

[0009] Preferably, the front and rear ends of the concave plate are both installed with a first fixing block, the interiors of the two first fixing blocks are both threaded with screws, the left ends of the two screws are movably connected to a second fixing block, and the two second fixing blocks are respectively installed at the front and rear ends of the baffle.

[0010] Preferably, a sliding groove is provided on the lower wall of the pushing trough.

[0011] Preferably, a motor is installed at the left end of the moving block, the output end of the motor extends into the slide groove and is fixedly connected to a screw rod, a threaded block is provided on the outer surface of the screw rod, and the upper end of the threaded block is fixedly connected to a moving plate.

[0012] Preferably, the right end of the screw rod is movably connected to the right inner wall of the slide groove, and the threaded block is slidably connected in the slide groove.

[0013] Preferably, a hopper is installed at the right end of the concave plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting the pusher component, the pusher trough, the concave plate, the baffle and the first electric cylinder to work together, the work efficiency can be improved. When in use, the round bar workpiece is placed in the concave plate, and the first electric cylinder is controlled to drive the moving block to move to the right, so that the pusher trough moves to the bottom between the concave plate and the baffle. The bar falls into the pusher trough under the influence of gravity. Then, the first electric cylinder is controlled to drive the moving block to the left, so that the bar moves to the front of the push rod. Finally, the second electric cylinder is controlled to drive the push rod to move forward, so that the bar enters the front pneumatic chuck. Automatic loading can be completed without manual loading, reducing the operation time of each process, ensuring the overall production rhythm, and improving production efficiency.

[0016] 2. By arranging the first fixed block, the screw, the second fixed block, the lead screw, the threaded block and the movable plate to cooperate with each other, it is convenient to load larger-sized bars. When the bar is thicker, the two screws are rotated to make the baffle away from the concave plate, so that the bar can be placed between the concave plate and the baffle. Then, the motor is controlled to drive the lead screw to rotate, and the lead screw drives the movable plate to move to the left through the threaded block, so that the volume of the push trough becomes larger, which facilitates the bar to fall to the center position of the push trough, thereby improving the applicability of the device.

As a specific embodiment, four pneumatic chucks 3 are provided, and the pneumatic chucks 3 are used to fix the bar material. A guide rail 4 is installed in the middle of the upper end of the base plate 1, and there are two guide rails 4. A pushing component 6 is installed at the front of the upper end of the base plate 1, and a first electric cylinder 9 is installed at the right upper end of the base plate 1. A moving block 5 is movably connected to the outer surface of the guide rail 4, and a pushing groove 7 is provided at the upper left end of the moving block 5.

[0026] During use, the round rod workpiece is placed in the concave plate 10, and the first electric cylinder 9 is controlled to drive the moving block 5 to move to the right, so that the push groove 7 moves to the bottom between the concave plate 10 and the baffle 11. The rod material falls into the push groove 7 under the influence of gravity, and then the first electric cylinder 9 is controlled to drive the moving block 5 to move to the left, so that the rod material moves to the front of the push rod 62.
