DETAILED DESCRIPTION

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] In order to solve the problem that tapping position deformation may occur due to uneven force when relying solely on edge fixation, the following technical solution is proposed: Figure 1 - Figure 10 As shown, in this embodiment, a tapping device suitable for sheet metal processing includes a base 1 and a column 2. The column 2 is arranged in the middle of the rear end of the base 1. The upper end of the column 2 is equipped with a cross rail 3 facing the front side, and the lower side of the cross rail 3 is slidably provided with an integrated drilling and tapping module.

[0033] Reference Figure 1 and Figure 9 As shown, the integrated drilling and tapping module includes a switching block 30 and a cross-arranged tapping assembly 4 and a drilling assembly 5. A sliding block 29 is installed in the middle of the inner bottom of the cross rail 3. The switching block 30 is arranged on the front side of the lower end of the sliding block 29. The tapping assembly 4 includes a tapping cone 10 arranged at the lower end of the switching block 30. The drilling assembly 5 includes a drill bit 11 arranged on the outside of the switching block 30. A motor 3 28 connected to the sliding block 29 is provided in the middle of the rear side of the switching block 30. The output end of the motor 3 28 is connected to the switching block 30 for controlling the deflection angle of the tapping assembly 4 and the drilling assembly 5.

[0034] The integrated drilling and tapping module uses a rotating shaft flip structure to achieve rapid switching between the tapping cone 10 and the drill bit 11, and the entire module slides horizontally on the cross rail 3 to adapt to different tapping positions on the sheet metal part for tapping operations. Specifically, the motor 3 28 is started to drive the switching block 30 to rotate, and the switching block 30 drives the tapping cone 10 and the drill bit 11 on the outer ring side to change positions, thereby completing the seamless connection between drilling and tapping operations, reducing the disadvantage that drilling and tapping require the movement of the sheet metal part.

[0035] Reference Figure 1 and Figure 7 As shown, a deflection frame 6 is rotatably provided at the upper end of the base 1, and an adaptive suction clamping assembly is commonly installed between the upper ends of the deflection frames 6. The adaptive suction clamping assembly includes a wheel seat 7 rotatably provided between the deflection frames 6, and a push rod seat 13 is commonly installed between the outer edges of the inner sides of the wheel seat 7. Magnetic ring seats 12 are slidably installed at both ends of the push rod seat 13. A pair of magnetic ring seats 12 are embedded with an adsorption magnetic block 15. Support plates 14 are installed on both sides of the push rod seat 13, and a plurality of flexible support columns 16 are installed on the support plates 14, wherein the upper end height of the flexible support column 16 exceeds the upper end of the push rod seat 13 but does not exceed the upper end of the adsorption magnetic block 15.

[0036] Reference Figure 4 、 Figure 5 and Figure 6 As shown, a guide hole 19 is opened in the middle of the push rod seat 13, and a moving block 18 is installed on the push rod seat 13 through the guide hole 19. The upper end of the moving block 18 passes through the guide hole 19 and is connected to the magnetic ring seat 12. A double-threaded screw 17 is installed between the pair of moving blocks 18. The lower end of the magnetic ring seat 12 is opened with a matching groove 20 that matches the upper end of the push rod seat 13, which is used for the horizontal sliding limit of the pair of magnetic ring seats 12 to adjust the spacing;

[0037] During this process, the adaptive suction clamping component can be adaptively adjusted according to the size specifications of the sheet metal to be tapped, and a flexible support is formed by a ring-shaped electromagnet array and a positioning column structure. The clamping force is adjustable and fits the tapping area, avoiding the deformation of the tapping position caused by uneven force on thin sheet metal parts. Specifically: the rotation of the double-threaded screw 17 is controlled by a driving component preset in the wheel seat 7. The driving component can be a conventional driving motor in the prior art. A micro motor is used here and is marked as motor four. When motor four is started, it drives the double-threaded screw 17 to rotate, and the magnetic seat 12 on the double-threaded screw 17 moves in opposite or similar directions, thereby adjusting the distance between the two groups of adsorption magnetic blocks 15 until it adapts to the size of the sheet metal to be tapped. Under the cooperative clamping action of the adsorption magnetic blocks 15 distributed in the ring array, the bottom and outer sides of the sheet metal to be tapped are wrapped and clamped, avoiding the problem of deformation caused by uneven force due to relying solely on edge clamping.

[0038] Basic principle: On the one hand, this embodiment uses a rotating shaft flip structure through the integrated drilling and tapping module to realize the rapid switching of the tapping cone 10 and the drill bit 11, and the whole body slides horizontally with the cross rail 3, so as to adapt to different tapping positions on the sheet metal for tapping operations; on the other hand, the adaptive suction clamping component can be adaptively adjusted according to the size specifications of the sheet metal to be tapped, and the annular electromagnet array is combined with the positioning column structure to form a flexible support. The clamping force is adjustable and fits the tapping area, avoiding the deformation of the tapping position caused by uneven force on thin sheet metal parts.

[0039] Example 2:

[0040] In order to solve the problem that metal debris in the tapping process affects the processing accuracy, the adjustable deflection structure is combined with the pneumatic suction + gravity sedimentation debris suction method to achieve comprehensive collection of metal debris; Figure 1 - Figure 8 As shown, a rotating plate 23 is installed on the inner side of the lower end of one of the deflection frames 6, and a motor 1 21 is provided above the rotating plate 23. The output end of the motor 1 21 is connected to the rotating plate 23. An arc-shaped rail groove 24 is installed on the upper surface of the base 1 corresponding to the other deflection frame 6. The deflection frame 6 rotates axially with the output shaft of the motor 1 21 through the arc-shaped rail groove 24. The upper end of the deflection frame 6 near the motor 1 21 is equipped with a motor 22 connected to the wheel seat 7 for controlling the rotation of the wheel seat 7.

[0041] When performing a tapping operation on a sheet metal workpiece to be tapped, the position of the sheet metal workpiece in the adaptive suction clamping assembly is deflected according to the position to be tapped, thereby completing accurate tapping at different positions. Specifically, the motor 21 is started to drive the deflection frame 6 to swing, and the deflection frame 6 drives the wheel seat 7 to produce a horizontal offset, so that the vertical corresponding position of the tapping cone 10 or the drill bit 11 is offset in an arc shape. The fully automatic positioning measure facilitates the accurate definition of the tapping position, which is conducive to improving the tapping efficiency.

[0042] The rotation control of the wheel seat 7 can also realize the tapping conversion of the sheet metal parts to be tapped in different adaptive suction clamping assemblies, thereby realizing continuous tapping processing and improving tapping efficiency. Specifically, the motor 22 drives the wheel seat 7 to rotate, and after the tapping of a single sheet metal part is completed, it rotates 60° to perform the tapping operation of the next sheet metal part to be tapped.

[0043] Reference Figure 2 and Figure 8As shown, a chip removal box 8 is obliquely arranged at the lower end between the deflection frame 6, a filter screen 25 is installed in the inner middle part of the chip removal box 8, a suction pipe 9 connected to the pneumatic suction device is installed at the lower end of the chip removal box 8, and a rotating rod 27 rotatably connected to the deflection frame 6 is installed at both ends of the chip removal box 8. A suction port 26 is opened in the part of the chip removal box 8 corresponding to the suction pipe 9. It is important to note that: during the tapping operation of the sheet metal parts, the metal debris generated by drilling and tapping can fall downward during the continuous flipping process, and the suction pipe 9 arranged at the bottom of the chip removal box 8 continuously sucks the small debris, and the filter screen 25 inside the chip removal box 8 can complete the interception of large spiral debris, so that large debris and small debris can be separately sucked and collected, and the entire chip removal box 8 is in an inclined state during the debris collection process, thereby improving the collection efficiency.

[0044] Basic principle: On the one hand, this embodiment realizes rapid position adjustment during the drilling and tapping process through the deflectable structural design of the adaptive suction and clamping component. The fully automatic positioning measures facilitate the accurate definition of the tapping position and improve the tapping efficiency. On the other hand, the separation and collection method of pneumatic suction + gravity sedimentation is used to achieve comprehensive suction of metal debris, avoiding the problem of metal debris affecting the processing accuracy.

[0045] Example 3:

[0046] Reference Figure 1 - Figure 10 As shown, this embodiment combines the technical contents of the first and second embodiments to propose a tapping method suitable for sheet metal processing, including the following steps:

[0047] Step 1: The motor 4 preset in the wheel seat 7 controls the rotation of the double-threaded screw 17. When the motor 4 is started, it drives the double-threaded screw 17 to rotate, and the magnetic seat 12 on the double-threaded screw 17 moves in the opposite or similar directions, thereby adjusting the spacing between the two sets of adsorption magnetic blocks 15 until it is adapted to the size of the sheet metal to be tapped. Under the cooperative clamping action of the adsorption magnetic blocks 15 distributed in the annular array, the bottom and outer sides of the sheet metal to be tapped are wrapped and clamped, avoiding the problem of uneven force and deformation caused by relying solely on edge clamping;

[0048] Step 2: The motor 3 28 is started to drive the rotating block 30 to rotate, and the rotating block 30 drives the tapping cone 10 and the drill bit 11 on the outer ring side to change positions, thereby completing the seamless connection of the drilling and tapping operations, reducing the disadvantage of drilling and tapping requiring the movement of sheet metal parts;

[0049] Step 3: The motor 1 21 is started, driving the deflection frame 6 to swing, and the deflection frame 6 drives the wheel seat 7 to produce a horizontal offset, so that the vertical corresponding position of the tapping cone 10 or the drill bit 11 is offset in an arc shape. The fully automatic positioning measure facilitates the accurate definition of the tapping position, which is conducive to improving the tapping efficiency;

[0050] Step 4: During the tapping operation of the sheet metal part, the metal debris generated by drilling and tapping can fall downward during the continuous turning process. The suction pipe 9 provided at the bottom of the chip removal box 8 continuously sucks out the small debris, and the filter screen 25 inside the chip removal box 8 can intercept the large spiral debris, so that the large debris and the small debris can be sucked out separately. During the debris collection process, the entire chip removal box 8 is in an inclined state, thereby improving the collection efficiency.

[0051] Step 5: After completing the tapping operation of the sheet metal to be tapped in a single adaptive suction clamping assembly, motor 22 drives the wheel seat 7 to rotate, and after the tapping of a single sheet metal to be tapped is completed, it rotates 60° to perform the tapping operation of the next sheet metal to be tapped. After rotating 5 times, the continuous tapping operation of a group of sheet metal to be tapped is completed, thereby improving the tapping processing efficiency.

[0052] In summary, the present invention, on the one hand, realizes rapid switching between the tapping tap 10 and the drill bit 11 by adopting a rotating shaft flip structure through an integrated drilling and tapping module, and the whole body slides horizontally on a cross rail 3, thereby adapting to different tapping positions on the sheet metal part for tapping operations; on the other hand, the adaptive suction clamping component can be adaptively adjusted according to the size specifications of the sheet metal part to be tapped, and the annular electromagnet array and the positioning column structure form a flexible support, the clamping force is adjustable and fits the tapping area, avoiding the problem of deformation of the tapping position caused by uneven force on thin sheet metal parts;

[0053] The deflectable structural design of the adaptive suction clamping component can also achieve rapid position adjustment during the drilling and tapping process. The fully automatic positioning measures facilitate the accurate definition of the tapping position and improve the tapping efficiency. The combination of pneumatic suction + gravity sedimentation separation and collection can achieve comprehensive suction of metal debris, avoiding the problem of metal debris affecting the processing accuracy.
