[0002] A drilling and tapping machine is a processing equipment that is used to drill holes in various structures such as machine casings, equipment end faces, nuts, flanges, etc., and to process internal threads or screws on the inner side surfaces of holes in various parts with through holes or blind holes of different specifications, such as machine casings, equipment end faces, nuts, flanges, etc.

[0003] After searching: A drilling and tapping machine with the authorization announcement number CN208322675U belongs to the technical field of mechanical automation processing equipment. The key points of its technical solution include a base and a turntable controlled by a numerical control system and rotating intermittently on the base. There are several workpiece fixtures in a circular array on the turntable. Drilling machines and tapping machines controlled by the numerical control system are arranged on the base at intervals along the circumference of the turntable. A control panel is provided on one side of the base, and the numerical control system is arranged in the control panel.

[0004] However, the above-mentioned drilling and tapping machine still has some shortcomings. Although the design has the advantages of saving manpower and improving product quality, personnel are required to load the workpiece during loading, and the workpiece fixture requires personnel to manually adjust the clamping block to clamp and disassemble the workpiece, which is not conducive to the disassembly and loading of the workpiece, and reduces the efficiency of workpiece processing. Therefore, we propose a drilling and tapping machine to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings and to provide a drilling and tapping machine.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0015] The cam is driven by a pneumatic cylinder to move the workpiece downwards and the pneumatic chuck is opened to allow the workpiece to fall into the placement slot. The servo motor in the station switching mechanism drives the counterclockwise rotation of the rotating disk, thereby switching the positions of the four positioning plates, so that the positioning plates with the workpiece are rotated to the bottom of the drilling machine, and the workpiece with the drilled hole is rotated forward to the bottom of the tapping machine, while the workpiece with the tapping is rotated to the bottom of the unloading mechanism. At this time, the two cylinders three are started, and the output shafts of the two cylinders three drive the fixing rods to extend into the through hole and firmly abut against the outside of the workpiece, thereby clamping and fixing the workpiece in the placement slot to avoid deviation and shaking that affect the accuracy of drilling and tapping.

[0016] The workpiece is then ejected from the slot and removed from the workpiece by the unloading mechanism, and the ejector is driven by the air cylinder to move the ejector rod upwards and insert the ejector rod into the chip discharge hole. The ejector rod is then removed from the slot and removed from the workpiece by the unloading mechanism. The ejector rod is then driven by the air cylinder to move downwards and out of the chip discharge hole without interfering with the rotation switching of the rotary disk. When one round of processing is completed, the air cylinder is driven by the air cylinder to move the ejector rod downwards and out of the chip discharge hole without interfering with the rotation switching of the rotary disk.

[0025] Specifically, the loading mechanism and the unloading mechanism have the same structure, both of which include a rotating motor 9 fixedly connected to the top of the base 1, and a cylinder 10 is fixedly connected to the output shaft of the rotating motor 9, and a cylinder 2 11 is fixedly connected to the output shaft of the cylinder 10, and a pneumatic chuck 12 is fixedly connected to the output shaft of the cylinder 2 11. When loading and unloading, the workpiece can be clamped or opened and lowered by the pneumatic chuck 12, and the height of the pneumatic chuck 12 can be adjusted by the cylinder 10, and the lateral position of the pneumatic chuck 12 can be adjusted by the cylinder 2 11. The orientation of the pneumatic chuck 12 can be adjusted by the rotating motor 9, so as to facilitate the clamping of the workpiece into the placement slot 6 for loading, and the workpiece can be removed from the placement slot 6 for unloading.

[0026] Specifically, two mounting grooves are provided on the top of the base 1 , and the two rotating motors 9 are fixedly connected in the corresponding mounting grooves, respectively, which is conducive to installing and fixing the rotating motors 9 .

The output shaft of the cylinder three 15 is fixedly connected to the fixing rod 14, and a through hole 17 is opened on one side of the positioning plate 5. The fixing rod 14 cooperates with the through hole 17. After the rotation switching is completed, the two cylinders three 15 are started, and the output shafts of the two cylinder threes 15 drive the fixing rod 14 to extend into the through hole 17 and firmly abut against the outside of the workpiece, so that the workpiece can be clamped and fixed in the placement groove 6 to avoid offset and shaking that affects the accuracy of drilling and tapping.

[0028] Specifically, the work station switching mechanism includes a servo motor 16 fixedly connected to the bottom of the base 1, and a rotating disk 2 is fixedly connected to the output shaft of the servo motor 16. Four positioning plates 5 are fixedly connected to the top of the rotating disk 2. The four positioning plates 5 are distributed at equal intervals on the circumference of the rotating disk 2.

[0031] The workpiece is then clamped to the top of the placement slot 6 by the loading mechanism arranged on the top rear side of the base 1, and then the pneumatic chuck 12 is moved down by the cylinder 10, and finally the pneumatic chuck 12 is opened, so that the workpiece falls into the placement slot 6, and the output shaft of the servo motor 16 in the station switching mechanism drives the rotating disk 2 to rotate 90 degrees counterclockwise, thereby switching the positions of the four positioning plates 5, so that the positioning plates 5 with the workpiece are rotated to the bottom of the drilling machine 3, and the workpiece with the drilled hole is rotated forward to the bottom of the tapping machine 4, and the workpiece with the tapping is rotated to the bottom of the unloading mechanism. At this time, the two cylinders 3 15 are started, and the output shafts of the two cylinders 3 15 drive the fixing rod 14 to extend into the through hole 17 and firmly abut against the outside of the workpiece, thereby clamping the workpiece in the placement slot 6 to avoid offset shaking and affecting the accuracy of drilling and tapping.
