Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to an automatic tapping machine which is convenient for fixing a workpiece. Background Art

[0002] A tapping machine is a type of machining equipment used to create internal threads, screws, or threads on the inside surfaces of various through-holes or blind holes of varying sizes, such as machine housings, equipment end faces, nuts, and flanges. It is also known as a tapping machine, thread tapping machine, thread tapping machine, or automatic tapping machine.

[0003] For example, the Chinese patent (CN113814489A) specifically describes an automatic tapping machine, comprising a box body and a clamping mechanism; a square groove is provided on the inner wall at the center of the top of the box body; a motor is provided inside the square groove; the output end of the motor is fixedly connected to a support platform; the clamping mechanism is provided on the top of the support platform; the clamping mechanism comprises a mounting seat, a fixing plate, a threaded rod, a handwheel and a fixing block; the mounting seat is fixedly connected to the top of the support platform; the fixing plate is symmetrically fixedly connected to both sides of the top of the mounting seat; the threaded rod is threadedly connected to the inside of the fixing plate; the handwheel is fixedly connected to the end of one side of the threaded rod; the fixing block is provided at the end of the other side of the threaded rod; by providing the clamping mechanism, it is convenient to clamp and fix the parts to be tapped, thereby improving the tapping processing efficiency of the parts.

[0004] However, in the above scheme, the workpiece needs to be fixed manually. During the tapping process, the operator's hands may be close to the rotating tool or machine tool, which increases safety hazards and easily leads to accidental injuries. Manual operation will significantly reduce processing efficiency in mass production, and when fixing the workpiece, it is necessary to screw the threaded rods on both sides at the same time. Once there is a lack of synchronization, the workpiece is very likely to shift, resulting in a deviation in the tapping position, affecting the tapping accuracy. In response to the above problems, an automatic tapping machine that is easy to fix the workpiece is proposed to solve them. Utility Model Content

During the tapping process, the operator's hands may be close to the rotating tools or machine tools, which increases safety hazards and easily leads to accidental injuries. Manual operation will significantly reduce processing efficiency in mass production, and when fixing the workpiece, it is necessary to screw the threaded rods on both sides at the same time. Once there is a lack of synchronization, the workpiece is very likely to shift, resulting in a deviation in the tapping position, affecting the tapping accuracy.

[0022] Furthermore, the clamping assembly 8 includes two mounting plates 801, which are respectively fixedly connected to the left and right sides of the upper surface of the support frame 1. The outer sides of the upper surfaces of the two mounting plates 801 are fixedly connected with sliders 802, and the interiors of the two sliders 802 are slidably connected with slide rods 803. The two slide rods 803 are fixedly connected with an L-shaped plate 804 on one side close to the middle of the conveyor belt 2. The design of the L-shaped plate 804 increases the clamping area and improves the clamping effect.

[0023] The inner sides of the upper surfaces of the two mounting plates 801 are rotatably connected to the first connecting rods 805, the side of the upper surfaces of the two first connecting rods 805 away from the rotating axis of the first connecting rod 805 is rotatably connected to the second connecting rod 806, the bottoms of the two second connecting rods 806 away from the side of the first connecting rod 805 are rotatably connected to the third connecting rod 807, and the other ends of the two third connecting rods 807 are rotatably connected to the left and right ends of the upper side of the L-shaped plate 804 respectively.

[0024] Specifically, an arc-shaped guide bar 808 is fixedly connected to the left side of the upper surface of the left mounting plate 801. In addition, the arc-shaped guide bar 808 ensures that the workpiece can be accurately aligned, further improving the processing accuracy.

[0025] Specifically, the drive assembly 7 includes two mounting bars 701, which are fixedly connected to the mounting plates 801 in the front and rear clamping assemblies 8, respectively. A support plate 703 is fixedly connected in the middle between the two mounting bars 701, and a fixing plate 702 is fixedly connected to the right side between the two mounting bars 701. The support plate 703 prevents damage to the device due to excessive force. It also provides a stable support surface for the workpiece, ensuring smooth tapping.

[0026] Specifically, a cylinder 704 is fixedly installed at the bottom of the fixed plate 702, and a push block 705 is fixedly connected to the output end of the cylinder 704. The front and rear sides of the bottom of the push block 705 are both rotatably connected to the fourth connecting rod 706.

[0027] Specifically, the bottoms of the two fourth connecting rods 706 are rotatably connected to push plates 707, and the tops of the two push plates 707 are fixedly connected to transmission rods 708. The left and right ends of the transmission rods 708 are rotatably connected to the middle of the bottom surfaces of the second connecting rods 806 on both sides. The driving assembly 7 provides power through the cylinder 704, and transmits the power to the L-shaped plate 804 through the connecting rod mechanism, thereby realizing the clamping and loosening operations of the workpiece.

[0028] Working principle: When the device is in use, the workpiece to be processed is transported by the conveyor belt 2, and the guide bars 808 on the front and rear sides ensure that the workpiece can be located in the middle position of the conveyor belt 2. When the infrared sensor 6 detects that the workpiece is directly below the tapping mechanism 4, the output end of the cylinder 704 contracts and pulls the push plates 707 on both sides to move inward through the push block 705 and the fourth connecting rod 706. The second connecting rod 806 is pulled by the transmission rod 708 and gradually changes from an inclined shape to a vertical shape, and enters to push the L-shaped plate 804 to approach the middle of the conveyor belt 2. The workpiece is clamped by the L-shaped plates 804 on both sides. After clamping, the workpiece is tapped by the tapping mechanism 4. During tapping, the load-bearing plate 703 is used to bear the pressure during tapping and the gravity of the workpiece. When tapping is completed, the output end of the cylinder 704 extends to open the L-shaped plates 804 on both sides, and the conveyor belt 2 resumes operation to transport the processed workpiece to the next process.
