Technical Field
[0001] This utility model relates to the field of automatic CNC horizontal boring machine technology, specifically an automatic CNC horizontal boring machine with adaptive clamping function. Background Technology
[0002] An automatic CNC horizontal boring machine is a precision machining tool mainly used for boring operations. Its main feature is that the boring spindle is horizontal. The automatic CNC horizontal boring machine is equipped with a CNC system, which enables automated machining. Boring is a metal cutting method in which a boring bar rotates on the workpiece and makes axial feed motion to perform internal hole machining on the workpiece, such as boring cylindrical holes, conical holes, and threaded holes. The key feature of an automatic CNC horizontal boring machine with adaptive clamping function is that it has an adaptive clamping function.
[0003] However, existing automatic CNC horizontal boring machines with adaptive clamping function lack the ability to clamp irregularly shaped workpieces and workpieces of different sizes. When using them, traditional clamping structures make surface contact, line contact or even point contact between the clamping parts and the workpiece, which makes it difficult to ensure the stability of the workpiece position. During the processing, the workpiece may shift or even fall off, resulting in damage to the workpiece and the boring machine. Utility Model Content
[0004] The purpose of this invention is to provide an automatic CNC horizontal boring machine with adaptive clamping function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This automatic CNC horizontal boring machine with adaptive clamping function, through the arrangement of clamping bars, slide tubes, elastic ropes and rotating blocks, allows the workpiece to be processed to be placed on the placement plate during use. The second motor drives the bidirectional lead screw to rotate, causing the two sliders to slide towards each other, causing the two clamping plates to come together and initially clamp the workpiece. The first motor drives the connecting rod to rotate a certain amplitude, causing the rotating block to rotate, causing the elastic rope to slide inside the slide tube, and causing the clamping bars to slide inside the slide tube. When the clamping bars touch the workpiece, they are obstructed and stop sliding.

[0014] 2. This automatic CNC horizontal boring machine with adaptive clamping function, through the arrangement of a turntable, a rotating rod, and a motor, is used such that when the motor is started, it drives the rotating rod to rotate on the machine bed, which in turn drives the turntable to rotate around the rotating rod as the central axis until the workpiece being clamped faces the boring spindle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:
[0022] An automatic CNC horizontal boring machine with adaptive clamping function includes a bed 1, a turntable 2 rotatably connected to the outer surface of the bed 1, a hollow block 3 fixedly connected to the top of the turntable 2, a circular plate 4 fixedly connected to the top of the hollow block 3, several slide tubes 5 fixedly connected to the top of the circular plate 4, elastic ropes 6 slidably connected to the inner wall of the slide tubes 5, a clamping strip 7 fixedly connected to one end of the elastic rope 6 near the edge of the circular plate 4, a groove 8 opened at the top of the slide tubes 5, the clamping strip 7 slidably connected to the inner wall of the groove 8, a rotating block 9 fixedly connected to one end of the elastic rope 6 near the center of the circular plate 4, a connecting rod 10 fixedly connected to the inner top wall of the rotating block 9, and a motor output shaft 11 fixedly connected to one end of the connecting rod 10 away from the inner top wall of the rotating block 9. In use, the workpiece is placed on a placement plate 21. The starting motor 11 drives the connecting rod 10 to rotate a certain amplitude, which in turn drives the rotating block 9 to rotate, causing the elastic rope 6 to slide inside the slide tube 5, and causing the clamping strip 7 to slide inside the slide tube 5. When the clamping strip 7 touches the workpiece, it stops sliding due to obstruction. All the clamping strips 7 stop at different positions according to the outer shape of the workpiece, thus assisting in clamping the workpiece. Since different workpieces have different external dimensions and shapes, traditional clamping methods often result in planar contact, or even line or point contact, when they come into contact with such workpieces. Therefore, the clamping effect is not ideal, and the workpiece may shake or even fall off during the processing. However, the setting of many clamping strips 7 in this device can effectively assist in clamping workpieces of different sizes and shapes.
[0023] In this embodiment, preferably, a bidirectional lead screw 12 is inserted inside the hollow block 3. Both ends of the bidirectional lead screw 12 are slidably connected to sliders 13. A clamping plate 14 is fixedly connected to the top of the sliders 13. One end of the bidirectional lead screw 12 is fixedly connected to the output shaft of a second motor 15. In use, the workpiece to be processed is placed on the placement plate 21, and the second motor 15 is started to drive the bidirectional lead screw 12 to rotate, causing the two sliders 13 to slide towards each other, and causing the two clamping plates 14 to move closer together and initially clamp the workpiece. Using the rotation of the bidirectional lead screw 12 to drive the clamping plates 14 to clamp the workpiece is a common clamping method. In this device, this method is used for initial clamping.
[0024] In this embodiment, preferably, a rotating rod 16 is rotatably connected inside the turntable 2, and a circular groove 17 is provided on the side of the bed 1 near the turntable 2. The rotating rod 16 is rotatably connected to the inner wall of the circular groove 17. The output shaft of the motor 18 is fixedly connected to the end of the rotating rod 16 near the motor 11. In use, the motor 18 is started to drive the rotating rod 16 to rotate on the bed 1, which drives the turntable 2 to rotate around the rotating rod 16 as the central axis until the clamped workpiece faces the boring spindle 24. The spindle box 23 provides power to rotate the boring spindle 24 for finishing. Since the boring spindle 24 of the horizontal boring machine is placed horizontally, the surface of the workpiece to be processed must face the boring spindle 24. First, the workpiece is placed horizontally and clamped, and then the turntable 2 is rotated to a suitable position to process the workpiece, thereby achieving a more stable placement and simpler operation.
[0025] In this embodiment, preferably, a circular plate 4 is fixedly connected to the bottom of the motor 11, and a rotating groove 19 is opened on the top of the rotating block 9. A clamping block 20 is rotatably connected to the inner wall of the rotating groove 19, and a placement plate 21 is fixedly connected to the top of the clamping block 20. When in use, the motor 11 drives the rotating block to rotate, and the workpiece to be processed is placed on the placement plate 21. The workpiece to be processed is clamped by the clamping plate 14, so the placement plate 21 will not rotate with the rotating block 9, ensuring the stability of the workpiece to be processed when it is clamped.
[0026] In this embodiment, preferably, a support block 22 is rotatably connected to the outer surface of the bidirectional lead screw 12 near the slider 13. A turntable 2 is fixedly connected to the bottom of the support block 22. In use, the support block 22 supports the bidirectional lead screw 12 and does not prevent it from rotating, thus providing support for the clamping process of the clamping plate 14.
[0027] In this embodiment, preferably, a spindle box 23 is fixedly connected to the upper surface of the bed 1 away from the turntable 2. A boring spindle 24 is inserted into the side of the spindle box 23 near the turntable 2. In use, the spindle box 23 is used to install the boring spindle 24 and provide power to the boring spindle 24 to make it rotate. The boring spindle 24 performs boring operations on the workpiece.
[0028] Working Principle: In this embodiment, an automatic CNC horizontal boring machine with adaptive clamping function is used by placing the workpiece on the placement plate 21. The second motor 15 drives the bidirectional lead screw 12 to rotate, causing the two sliders 13 to slide towards each other, and causing the two clamping plates 14 to move closer together and initially clamp the workpiece. The first motor 11 drives the connecting rod 10 to rotate a certain range, causing the rotating block 9 to rotate, causing the elastic rope 6 to slide inside the slide tube 5, and causing the clamping strip 7 to slide inside the slide tube 5. When the clamping strip 7 touches the workpiece, it is blocked and stops sliding. All the clamping strips 7 stop at different positions according to the outer shape of the workpiece, and perform secondary clamping on the workpiece. The third motor 18 drives the rotating rod 16 to rotate on the bed 1, causing the turntable 2 to rotate around the rotating rod 16 as the central axis until the clamped workpiece faces the boring spindle 24. The spindle box 23 provides power to make the boring spindle 24 rotate, and the workpiece is then finished.
