[0002] Tapping machines are specialized equipment used for machining internal threads within forming machine tools, a sub-category of metal cutting machine tools. Their core function is to create threaded holes in metal workpieces using a rotating tap. They are widely used in industries such as machinery manufacturing, automotive parts, aerospace, and electronics.

[0003] In the prior art, when a tapping machine processes a workpiece, the workpiece is generally clamped and fixed by a vise. During use and observation, it is found that standard workpieces can be roughly divided into two types according to their shapes and sizes, namely square workpieces and cylindrical workpieces.

During the movement of the second gear 111, it can be restricted by the cooperation of the first horizontal plate 113 that is abutted against it by the limiting component, so that the second gear 111 will not rotate until the rectangular part of the clamping plate 112 contacts the workpiece and squeezes and clamps it.

Since the sphere 62 is eccentrically set, the curved plate 63 can be impacted by more liquid in the tangential direction, thereby improving its utilization of the liquid kinetic energy. When the sphere 62 rotates with the curved plate 63, it can rotate with the rubber rod 64. The rubber rod 64 will periodically hit the inner wall of the nozzle 6 and generate vibration. The vibration can be transmitted to the liquid outlet pipe 53 and the diverter plate 5, and the cuttings attached to their surfaces can be shaken off.

The cutting fluid sprayed from the outlet pipe 53 can flush the processing area on the surface of the workpiece, and the discharged cutting fluid together with the debris can be discharged through the holes on the surface of the support plate 7. The surface of the support plate 7 is sloped towards the holes to improve its discharge capacity for waste liquid. The discharged waste liquid can fall into the filter screen 73, and the filter screen 73 will intercept and collect the debris in the waste liquid. The connection between the filter screen 73 and the outer frame 72 and the connection between the support plate 7 and the placement plate 16 are all detachable, and no specific limitation is made here, so as to facilitate the subsequent removal of the debris in the filter screen 73.

[0033] Working principle: Place the workpiece on top of the placement plate 16. Taking a square workpiece as an example, start the first cylinder 17 to push the first rack 19 connected to its output end. The first rack 19 can slide along the machine tool 1 and mesh with the first gear 110. The first gear 110 will rotate and mesh with the other first rack 19. At this time, a pair of first racks 19 can move toward each other. During the movement of the first rack 19, the second gear 111 and the vertical rod 116 can bring the clamping plate 112 closer to the workpiece. During the movement of the second gear 111, it can be restricted by the cooperation of the first horizontal plate 113 that is against it through the limit assembly, so that the second gear 111 will not rotate until the rectangular part of the clamping plate 112 contacts the workpiece and squeezes it. The screw 14 can be rotated by starting the motor 13, and the mounting plate 15 can slide along the screw 14 and the vertical plate 12 under the action of the thread transmission. The mounting plate 15 can bring the processing assembly to the workpiece and tap the workpiece by the rotating tap.

Then the first cylinder 17 can be started to clamp the workpiece, and the second gear 111 will first move with the second rack 115 when it moves with the first rack 19. When the clamping plate 112 needs to be switched, the second gear 111 will first mesh along the second rack 115. At this time, the guide wheel 2 is not connected to the second cross plate 114. When the first gear 111 is in contact with the second rack 115 and the second gear 111 is in contact with the second rack 115, the second gear 111 is limited.By setting the ball 4, a certain processing gap can be left between the limit plate 32 and the square groove 3 to reserve installation space for the ball 4. The ball 4 can reduce the sliding friction between the limit plate 32 and the square groove 3, thereby reducing the wear on the surface of the limit plate 32 and the square groove 3; during the tapping process of the machining component on the workpiece, the cutting fluid can be pumped through the liquid inlet pipe 52, and the cutting fluid can be sprayed out from the end of the liquid outlet pipe 53 through the liquid inlet pipe 52 and the diverter plate 5. Since the liquid outlet pipe 53 is arranged in an arc shape, its end is directed toward the tap machining position, which can guide the cutting fluid spraying path, thereby improving the cooling effect of the cutting fluid on the tap in the machining area, and at the same time, the cutting fluid can also remove debris in the thread hole The cutting fluid can flow from the outlet pipe 53 to the inside of the nozzle 6 and be ejected from the holes on the surface of the nozzle 6. The curved plate 63 can rotate after being impacted by the liquid. Since the sphere 62 is eccentrically arranged, the curved plate 63 can be impacted by more liquid in the tangential direction, thereby improving its utilization of the kinetic energy of the liquid. When the curved plate 63 rotates, the sphere 62 can rotate with the rubber rod 64. The rubber rod 64 will periodically hit the inner wall of the nozzle 6 and generate vibration. The vibration can be transmitted to the outlet pipe 53 and the diverter plate 5, and the cutting fluid attached to its surface can be shaken off. The workpiece can be placed on the top of the support plate 7 before tapping. The size of the support plate 7 should be larger than the size of the workpiece, that is, the workpiece position Inside the support plate 7, the workpiece is tapped by the processing assembly when it is clamped by the clamping plate 112, and the cutting fluid sprayed from the liquid outlet pipe 53 can flush the processing area of ​​the workpiece surface, and the discharged cutting fluid together with the debris can be discharged through the holes on the surface of the support plate 7. The surface of the support plate 7 is sloped towards the holes to improve its discharge capacity for waste liquid. The discharged waste liquid can fall into the filter screen 73, and the filter screen 73 will intercept and collect the debris in the waste liquid. The connection between the filter screen 73 and the outer frame 72 and the connection between the support plate 7 and the placement plate 16 are all detachable, and no specific limitation is made here, so as to facilitate the subsequent removal of the debris in the filter screen 73; the waste liquid discharged from the filter screen 73 can fall to the drainage board 8 On the upper side, the drain plate 8 can isolate the waste liquid from the clamping assembly and the switching assembly. After being guided by the drain plate 8, the waste liquid can be discharged into the drain groove 82. Finally, the waste liquid can be discharged into the box body 83 through the drain groove 82 and collected by the box body 83. The sponge 9 is provided with a porous structure, which can absorb and slow down the waste liquid falling from the filter screen 73, thereby reducing the splashing of the waste liquid when it falls on the drain plate 8 and reducing the contamination of the waste liquid to other components. The accordion plate 10 is provided with a multi-layer folded structure, which can prevent dust and impurities diffused in the processing environment from contaminating the screw 14, preventing the screw from getting stuck and causing a decrease in precision.
