[0002] A tapping machine is a mechanical device specifically designed to machine internal threads on workpieces. Its core function is to drive a tap (a cutting tool with spiral grooves) to rotate and feed, cutting internal threads that meet specifications on pre-drilled holes or blanks. It is widely used in machinery manufacturing, automotive parts processing, hardware tool production, aerospace and other fields.

[0003] In the existing technology, there are various types of tapping machines, including the rocker arm tapping machine. The rocker arm can rotate 360 ​​degrees around the column and has the function of vertical lifting adjustment. Combined with the spindle box that can slide along the rocker arm, it can flexibly cover a large processing range and complete multi-position thread processing without frequent workpiece movement.

[0004] However, when using a rocker arm tapping machine, tapping is mainly done manually. When the tap comes into contact with the workpiece, improper control may cause the tap to deviate excessively from the center of the hole. This deviation will not only cause uneven force when the tap cuts in and cause tap wear, but also lead to quality defects in the processed thread, thus making the workpiece unusable.

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.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a technical solution: an adaptive error-proofing calibration system for a tapping machine, including a rocker arm tapping machine 11. A connecting frame 12 is provided at the connecting end of the rocker arm tapping machine 11, and the connecting end of the rocker arm tapping machine 11 is connected to the connecting end of the connecting frame 12. An L-shaped rod 13 is provided on the inner wall of the connecting frame 12, and the inner wall of the connecting rod is connected through to the outer side of the top end of the L-shaped rod 13. A cavity 14 is provided at the bottom end of the L-shaped rod 13, and the bottom end of the L-shaped rod 13 is fixedly connected to one side of the cavity 14. A scale 15 is provided on the inner wall of the cavity 14, and the inner wall of the cavity 14 is slidably connected through to the outer side of the scale 15. A rectangular plate 16 is provided at one end of the scale 15, and one end of the scale 15 is fixedly connected to one end of the rectangular plate 16. A pressure plate 17 is provided on the top side of the rectangular plate 16, and the top side of the rectangular plate 16 is fixedly connected to the bottom end of the pressure plate 17. A push plate 18 is provided on one side of the L-rod 17, and one side of the pressure plate 17 is slidably in contact with one end of the push plate 18. A motor bracket 110 is provided on one end of the push plate 18, and one side of the push plate 18 is fixedly connected to one side of the motor bracket 110. One side of the motor bracket 110 is fixedly connected to one side of the connecting frame 12. A guide rod 19 is provided on one side of the pressure plate 17, and one side of the pressure plate 17 is fixedly connected to one end of the guide rod 19. The outer side of the guide rod 19 is slidably connected through the inner wall of the L-rod 13. A mother plate 113 is provided on the inner wall of the L-rod 13, and one side of the mother plate 113 is slidably connected to the inner wall of the connecting frame 12. One end of the mother plate 113 is fixedly connected to the inner wall of the connecting frame 12. A second spring 114 is provided on the bottom side of the mother plate 113, and the bottom side of the mother plate 113 is fixedly connected to the top end of the second spring 114. The bottom end of the second spring 114 is fixedly connected to the inner wall of the L-rod 13.

[0027] In this embodiment, when the adaptive error-proofing calibration system for this type of tapping machine is in use, the rocker arm tapping machine 11 and the connecting frame 12 are integrated. The connecting frame 12 has a motor, which is connected to the connecting frame 12 via a motor bracket 110. An L-shaped rod 13 is connected through the inner wall of the connecting frame 12, and a cavity 14 is fixed to the bottom end of the L-shaped rod 13. The cavity 14 is annular, and two scales 15 are designed to slide along the inner wall of the cavity 14. The ends of the two scales 15 are in contact with each other. This allows the hand-controlled rocker arm tapping machine 11 to... During tapping, the cavity 14 first comes into contact with the workpiece. The cavity 14 is positioned at the tap hole by manual control. The radius of the tap hole is used as the boundary. The length occupied by the scale 15 within the tap hole range is observed to be basically consistent. If the difference exceeds the allowable range, the horizontal position of the rocker arm is finely adjusted until the length occupied by the scale 15 on both sides of the tap hole is within the allowable range. This completes the error prevention calibration. By combining mechanical structure with visual scale, rapid positioning and verification before tapping can be achieved, avoiding workpiece scrapping caused by tap hole center offset.

[0028] By installing rectangular plates 16 at one end of each of the two scales 15, and fixing pressure plates 17 on the top side of each of the two rectangular plates 16, the top of the pressure plate 17 has a certain slope. The slope is mainly used as a transition surface for the push rod. The push rod is fixed on one side of the motor bracket 110. Since the L rod 13 penetrates the inner wall of the connecting frame 12, when tapping, the connecting frame 12 is fed downward as a whole by the hand-controlled rocker arm. At this time, the motor bracket 110 and the push rod move down synchronously with the connecting frame 12. Their ends gradually come into contact with each other along the slope of the top of the pressure plate 17 and apply vertical downward pressure. Under the guidance of the slope, the distance between the two rectangular plates 16 is further separated, and the rectangular plates 16 are driven until the scale 15 is completely retracted into the cavity 14 seat to avoid interference with the tap.

[0029] By installing guide rods 19 on one side of the two pressure plates 17, the guide rods 19 penetrate the inner wall of the L rod 13, so that when the two pressure plates 17 are decomposed by pressure, the guide rods 19 can ensure the stability of the movement of the pressure plates 17 and ensure that the scale plate will not be deformed.

[0030] A mother plate 113 is installed between the L rod 13 and the connecting frame 12, and a spring 114 is installed between the mother plate 113 and the L rod 13. The elastic restoring force of the spring 114 keeps the cavity 14 seat in close contact with the workpiece surface. The elastic restoring force of the spring 114 can also assist the L rod 13 in driving the cavity 14 seat to quickly reset. At the same time, the reset spring of the scale 15 can realize the automatic return of the entire calibration mechanism.

[0031] Example 2

[0032] like Figure 2-5 As shown, a sub-plate 112 is provided on the inner wall of L-rod 13. The inner wall of L-rod 13 is fixedly connected to one end of sub-plate 112. A spring 111 is provided on one side of sub-plate 112. One side of sub-plate 112 is fixedly connected to one end of spring 111. The other end of spring 111 is fixedly connected to the inner side of guide rod 19.

[0033] In this embodiment, a sub-plate 112 is fixed to the inner wall of the L-rod 13. The sub-plate 112 is located in the inner wall of the guide rod 19. There is a spring 111 between the guide rod 19 and the sub-plate 112. After the tapping operation is completed, the operator lifts the rocker arm upward, and the motor bracket 110 drives the push rod to move upward synchronously. The pressure between the push rod and the pressure plate 17 is released, and under the elastic force of the reset spring 111, they automatically slide towards each other, and their ends return to the initial contact state, preparing for the next tapping calibration.

[0034] Working principle:

[0035] like Figure 1-5As shown, when the hand-controlled rocker arm tapping machine 11 is tapping, the cavity 14 will first come into contact with the workpiece. The cavity 14 is positioned at the tap hole by hand control. Using the radius of the tap hole as a boundary, the length occupied by the scale 15 within the tap hole range is observed to be basically consistent. If the difference exceeds the allowable range, the horizontal position of the rocker arm is finely adjusted until the length occupied by the scale 15 on both sides of the tap hole is within the allowable range, thus completing the error-proof calibration. Finally, the hand-controlled rocker arm drives the connecting frame 12 to move downwards as a whole. At this time, the motor bracket 110 and the push rod move downwards synchronously with the connecting frame 12. The ends gradually come into contact with the inclined surface at the top of the pressure plate 17 and apply vertical downward pressure. Under the guidance of the inclined surface, the distance between the two rectangular plates 16 is further separated, and the rectangular plates 16 are moved until the scale 15 is completely retracted into the cavity 14 seat to avoid interference with the tap. A guide rod 19 is installed on one side of the two pressure plates 17. The guide rod 19 penetrates the inner wall of the L rod 13. When the two pressure plates 17 are decomposed by pressure, the guide rod 19 can ensure the stability of the movement of the pressure plates 17 and ensure that the scale plate will not be deformed.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
