Description

Automatic loading and unloading mechanism of a grinding machine

Technical Field

The present application relates to the technical field of grinder use, and in particular to an automatic loading and unloading mechanism of a grinder.

Background Art

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding. Using a three-jaw chuck to fix the workpiece is one of the ways to fix the workpiece on a grinder. A three-jaw chuck is mainly composed of multiple jaws and a chuck. Multiple jaws on the chuck simultaneously move toward or away from the center of the chuck. The three-jaw chuck squeezes the workpiece on the chuck by moving jaws in different directions toward the center at the same time until the workpiece is clamped in the center of the chuck and the workpiece is fixed on the grinder.

The three-jaw chuck is mainly used to fix cylindrical workpieces, among which tubular workpieces are a type of cylindrical workpieces. When the three-jaw chuck of the bedroom grinder is used to actually fix the tubular workpiece, the worker is required to hold the tubular workpiece all the time until multiple claws clamp the tubular workpiece. When the fixed tubular workpiece needs to be disassembled, it is also necessary to hold the tubular workpiece until the claws are completely loosened to prevent the tubular workpiece from falling directly to the ground. The above are the loading and unloading steps of the bedroom grinder. It can be seen that each loading and unloading of the bedroom grinder requires the participation of workers to assist. When processing multiple tubular workpieces, the loading and unloading of the bedroom grinder requires a lot of human resources.

In view of the above problems, the present application proposes an automatic loading and unloading mechanism for a grinding machine.

The embodiment of the present application provides an automatic loading and unloading mechanism for a grinding machine, which can solve the problem in the related art that a large amount of manpower is required when processing multiple tubular workpieces.

Please refer to Figures 1 to 5, an automatic loading and unloading mechanism of a grinding machine, which includes: a grinding machine, a rotating plate 2 and a plurality of placement structures, a three-jaw chuck 1 is slidably connected to the grinding machine, the rotating plate 2 is arranged relative to the three-jaw chuck and the rotating plate 2 is rotatably connected to the grinding machine, a plurality of placement structures are circumferentially arranged on the rotating plate 2, the placement structure includes a placement cylinder 3, and a surrounding space for placing a tubular workpiece is provided on the placement cylinder 3;

The grinding machine has a first position, which is located on the moving path of the three-jaw chuck 1. When the rotating plate 2 drives the plurality of placement cylinders 3 to rotate, the placement cylinders 3 pass through the first position.

During the implementation process, tubular workpieces are placed on several placement cylinders 3. By rotating the rotating plate 2, any placement cylinder 3 is located at the first position. At this time, the three-jaw chuck moves to the first position to clamp the tubular workpiece on the placement cylinder 3 at the first position and returns it for processing. After the processing is completed, the three-jaw chuck re-puts the tubular workpiece on the surrounding space at the first position, and the rotating plate 2 rotates another placement cylinder 3 to the first position, and repeats the above process. No human intervention is allowed during the processing.

Furthermore, in this embodiment, a support plate 4 and a first power source 5 are also included;

The support plate 4 is connected to the grinding machine, and the first power source 5 is arranged on the support plate 4, and the first power source 5 drives the rotating plate 2 to rotate;

The first power source 5 is a motor, which is connected to the support plate 4. The output end of the motor passes through the support plate 4 and is connected to the rotating plate 2, so that the motor drives the rotating plate 2 to rotate. At the same time, the support plate 4 lifts the rotating plate 2 to a certain height.

Furthermore, in this embodiment, the placement structure also includes a rotation hole, an adjustment shaft 7, a plurality of telescopic holes 8, a plurality of top plates 9 and a plurality of pairs of springs 10;

A rotating hole is provided on the placement cylinder 3, and the adjustment shaft 7 is rotatably connected in the rotating hole. The side surface of the adjustment shaft 7 is wavy. A plurality of telescopic holes 8 correspond to a plurality of top plates 9 one by one. A plurality of telescopic holes 8 are circumferentially opened on the placement cylinder 3 and the telescopic holes 8 are connected to the rotating hole. The top plate 9 is slidably connected in the telescopic holes 8. Each pair of springs 10 corresponds to each top plate 9. A pair of springs 10 are respectively located on both sides of the top plate 9, and the two ends of the spring 10 are respectively connected to the top plate 9 and the placement cylinder 3;

The top plate 9 is extended and retracted on the placement cylinder 3, and the spring 10 presses the bottom of the top plate 9 against the side of the adjustment shaft 7. When the adjustment shaft 7 rotates on the placement cylinder 3, the bottom of the top plate 9 rises and falls with the side of the adjustment shaft 7. The rise and fall of the top plate 9 can be adjusted for tubular workpieces with different diameters.

A plurality of top plates 9 provide support from the inside of the tubular workpiece, making it easier for the tubular workpiece to be grasped by the three-jaw chuck 1 .

Specifically, in this embodiment, the placement structure further includes a first gear 11, a driving gear 13 and a second power source 14;

Also included is a gear ring 12;

The rotating hole is opened from a side close to the rotating plate 2 to a direction away from the rotating plate 2, the adjusting shaft 7 extends from the rotating hole to the rotating plate 2, the adjusting shaft 7 passes through the rotating plate 2 and is connected to the first gear 11, the gear ring 12 is rotatably connected to the rotating plate 2, the gear ring 12 is meshed with a plurality of first gears 11, the second power source 14 is connected to the rotating plate 2, the second power source 14 drives the driving gear 13 to rotate, and the driving gear 13 is meshed with the gear ring 12;

The second power source 14 is a motor, which drives the driving gear 13, the driving gear 13 drives the gear ring 12, and the gear ring 12 drives the first gears 11 to rotate, so that the motor drives all the top plates 9 to rise and fall at the same time, that is, to support or release the tubular workpiece at the same time;

After the tubular workpiece is processed, the top plate 9 is retracted to facilitate the processing of the tubular workpiece on the placement tube 3. After the tubular workpiece is put on, the top plate 9 is extended to lift the tubular workpiece.

Here’s how this application works:

During the implementation process, a number of placement cylinders 3 are pre-placed with tubular workpieces, and the motor rotates the rotating plate 2 so that any placement cylinder 3 is located at the first position. At this time, the three-claw chuck moves to the first position to clamp the tubular workpiece on the placement cylinder 3 at the first position and returns it for processing. After the processing is completed, the three-claw chuck re-sleeves the tubular workpiece on the surrounding space at the first position, and the rotating plate 2 rotates another placement cylinder 3 to the first position, and repeats the above process. No human intervention is allowed during the processing;

It should be pointed out that in the process of placing the tubular workpiece on the placing tube 3, the top plate 9 needs to be retracted first. After the tubular workpiece is placed, the top plate 9 extends out to support the tubular workpiece. In the process of removing the tubular workpiece from the placing tube 3, after the three-jaw chuck 1 clamps it, the top plate 9 is retracted and then the three-jaw chuck 1 moves to take away the tubular workpiece for processing.
