[0002] A drilling and tapping machine is a mechanical device that processes holes on radiator aluminum profiles and processes internal threads on the inner side of the holes by rotary cutting. It mainly includes a frame, a processing table, a drilling and tapping mechanism, and a cutting mechanism. The drilling and tapping mechanism is provided with a drilling head and a tapping head. During production, the strip-shaped radiator aluminum profile is first clamped on the drilling and tapping machine. However, traditional drilling and tapping machines mainly adopt the structure of a single drilling and tapping mechanism, and can only drill and tap one side of the radiator aluminum profile at a time. When one side of the profile is processed, the cutting mechanism is used to cut the profile into multiple independent workpieces. If multiple sides need to be processed, the workpiece needs to be manually clamped again, and the orientation of the workpiece is repeatedly adjusted to align the processed side with the drilling and tapping mechanism. Therefore, when the workpiece is processed on more than two sides, the workpiece needs to be clamped multiple times, and the clamping process is generally manual. Summary of the invention

The saw blade 41 reciprocates and moves horizontally in front of the moving fixture 5.

[0043] When the drive motor 42 drives the saw blade 41 to rotate at high speed, the saw blade moving device 43 drives the saw blade 41 to move horizontally, thereby cutting the profile into independent workpieces. In addition, the drive motor 42 and the saw blade moving device 43 are arranged below the mobile clamp 5, making the equipment layout more compact, fully utilizing the installation space, and making the equipment smaller.

[0044] The saw blade moving device 43 includes a fixed frame, on which a driving assembly 431 and a slide rail assembly 432 are arranged;

[0045] The driving assembly includes a driving motor, a coupling, a screw shaft and a screw nut.

[0048] Combined with the above structure, the working principle of the turntable receiving mechanism is as follows:

[0049] The long strip of profile is fed into the movable fixture 5, at which time the pressure cylinder 56 pushes the first pressure plate 57 downward and presses the profile on the movable bottom plate 52, and then the driving motor 42 works to drive the saw blade 41 to rotate at high speed, and then the saw blade moving device 43 drives the saw blade 41 to cut the profile, so that the profile is cut into a single workpiece.

[0050] The moving cylinder 53 works, pushing the movable bottom plate 52 to move the workpiece to the side. At the same time, the turntable motion device 23 drives the indexer 221 to slide to the loading position. During this process, the indexer 221 rotates the clamping fixture 21 to make the clamping station 201 in the first position.

[0051] The pressing cylinder 56 drives the first pressing plate 57 to release the workpiece, and then the side push cylinder 55 pushes the side push plate 59 to move sideways, thereby pushing the workpiece into the clamping station 201 of the rotating fixture 2.

[0052] The push cylinder 61 works to push the side push plate 62 to move toward the clamping station 201 to adjust the position of the workpiece, and then the clamping cylinder 213 works to move the second clamping plate 24 downward and clamp the workpiece.

[0053] The turntable motion device 23 drives the indexer 221 to slide in the processing direction to the processing position, and enables the workpiece to drill and tap the A surface at the first position, or rotate the rotary fixture 2 to enable the workpiece to drill and tap the C surface at the second position, or continue to rotate the rotary fixture 2 to enable the workpiece to drill and tap the B surface at the third position.
