Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping machine technology, specifically to an automatic clamping mechanism for CNC drilling and tapping machines. Background Technology

[0002] Tapping refers to using a certain torque to screw a tap into the bottom hole to be drilled to process internal threads. A tapping machine is a machine tool that uses a tap to process internal threads. It is the most widely used type of internal thread processing machine tool. According to national mechanical industry standards, tapping machine series are divided into: bench tapping machine, semi-automatic bench tapping machine, vertical tapping machine and horizontal tapping machine.

[0003] In existing technologies, most CNC drilling and tapping machines may not be able to effectively clamp workpieces of different sizes, requiring complex manual adjustments to adapt to varying workpiece dimensions. This results in cumbersome and inefficient clamping operations. Furthermore, they lack automatic clamping capabilities, relying too heavily on manual operation, which increases labor costs and the risk of operational errors. Therefore, we have introduced an automatic clamping mechanism for CNC drilling and tapping machines. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution: an automatic clamping mechanism for a CNC drilling and tapping machine, comprising: a machine body 1, wherein a safety light curtain 4 is provided at the center of the surface of the machine body 1, and the number of safety light curtains 4 is two sets;

[0026] Side plate 12, the side plate 12 is disposed inside the body 1, and there are two sets of side plates 12, and a lifting frame 8 is disposed between the two sets of side plates 12;

[0027] Workbench 15, the workbench 15 is located at the bottom of the machine body 1, the top of the workbench 15 is provided with mounting plate 17, and a cylinder A16 is provided on one side of the mounting plate 17.

[0028] The workbench 15 has a clamping mechanism at one end of the mounting plate 17. The spring 25 of the clamping mechanism drives the moving plate 20 to move so that the moving plate 20 clamps the workpiece.

[0029] The clamping mechanism includes a mounting plate 17 with a push plate 18 connected to the output end of cylinder A16. A slider 21 is connected to the surface of the mounting plate 17 and is fixedly disposed between the slider 21 and the mounting plate 17. A movable plate 20 slides on the surface of the slider 21, and there are two sets of movable plates 20. A limit rod 24 is connected between the two sets of movable plates 20. A spring 25 is sleeved on the surface of the limit rod 24 and is located between the two sets of movable plates 20. A connecting block 22 is connected to the inner side of the movable plate 20 and is fixedly disposed between the connecting block 22 and the movable plate 20. A positioning shaft 23 is connected to the surface of the connecting block 22 and is fixedly disposed between the positioning shaft 23 and the connecting block 22. An arc-shaped slot 19 for the movement of the positioning shaft 23 is opened on the surface of the push plate 18 and is integrally formed with the push plate 18.

[0030] A cylinder B7 is connected to the inner top of the body 1. The output end of the cylinder B7 is connected to the top of the lifting frame 8. The cylinder B7 can drive the lifting frame 8 to move in the Z-axis direction.

[0031] The two ends of the lifting frame 8 are slidably connected to the inside of the side plate 12. The side plate 12 limits the movement of the lifting frame 8. The inside of the side plate 12 is connected to a light rod 13 for limiting the movement of the lifting frame 8. The light rod 13 further limits the movement of the lifting frame 8.

[0032] The lifting frame 8 is internally connected to a cylinder C9, and the output end of the cylinder C9 is connected to a drive unit 10. The cylinder C9 can drive the drive unit 10 to move in the X-axis direction. The bottom of the drive unit 10 is connected to a drilling and tapping power unit 11, and the bottom of the drive unit 10 can perform drilling and tapping.

[0033] The bottom of the body 1 is connected to the bottom of the side plate 12, and a cylinder D14 is used to drive the side plate 12. The cylinder D14 can drive the side plate 12 to move in the Y-axis direction.

[0034] A controller 2 is hinged to the side of the body 1. The controller 2 can rotate on the side of the body 1. A display screen 3 is connected to the surface of the controller 2. Buttons are connected to the surface of the controller 2 below the display screen 3.

[0035] A control handwheel 5 is connected to the surface of the body 1, and an air blowing button 6 is connected to the surface of the body 1 below the control handwheel 5.

[0036] Specifically, during use, when it is necessary to clamp the workpiece, the cylinder A16 starts to work. The output end of the cylinder A16 pushes the push plate 18 to move. When the push plate 18 moves, the arc-shaped groove 19 on its surface interacts with the positioning shaft 23. Since the positioning shaft 23 is connected to the connecting block 22, and the connecting block 22 is connected to the inner side of the moving plate 20, the positioning shaft 23 will move in the arc-shaped groove 19, thereby driving the connecting block 22 to move. The movement of the connecting block 22 will cause the moving plate 20 to slide on the slider 21. Since the slider 21 is connected to the mounting plate 17, the movement direction of the moving plate 20 is restricted by the slider 21 and can only move along a specific direction. During the movement of the two sets of moving plates 20, since they are connected by the limit rod 24 and the spring 25 is sleeved on the surface of the limit rod 24 and located between the two sets of moving plates 20, the spring 25 will be compressed.

[0037] Next, the workpiece is placed between the two sets of moving plates 20. Then, the tension of the spring 25 itself drives the two sets of moving plates 20 to move closer to each other. The movement of the moving plates 20 is limited by the limiting rod 24, so that the two sets of moving plates 20 clamp the workpiece.

[0038] The movement of the two sets of moving plates 20 can be adapted to workpieces of different sizes;

[0039] The output end of cylinder B7 is connected to the top of the lifting frame 8. When cylinder B7 works, it can push the lifting frame 8 to move up and down inside the side plate 12. The light rod 13 inside the side plate 12 plays a limiting role for the lifting frame 8.

[0040] When the cylinder C9 inside the lifting frame 8 is working, the drive unit 10 connected to its output end can move left and right, and the drive unit 10 drives the drilling and tapping power unit 11 to move, thereby realizing the drilling and tapping operation.

[0041] When the cylinder D14 located at the bottom of the side plate 12 at the bottom of the body 1 is working, it can drive the side plate 12 to move, thereby forming movement in the X, Z and Y axes.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
