[0015] 1. In the present invention, on the one hand, the integrated drilling and tapping module adopts a rotating shaft type flipping structure to realize the rapid switching of the tapping cone and the drill bit, and the whole slides horizontally along the transverse rail, so as to adapt to different tapping positions on the sheet metal parts for tapping operations; on the other hand, the adaptive suction and clamping component can be adaptively adjusted according to the size specifications of the sheet metal parts to be tapped, and a flexible support is formed by the annular electromagnet array and the positioning column structure.

Detailed implementation manners

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] In view of the problem that relying only on edge fixation is likely to cause deformation of the tapping position due to uneven force, the following technical solutions are proposed: Refer to Figure 1 - Figure 10 As shown, in this embodiment, a tapping device adapted to sheet metal part 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 installed with a cross rail 3 facing the front side, and an integrated drilling and tapping module is slidably arranged under the cross rail 3;

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

[0034] Among them, the integrated drilling and tapping module adopts a rotating shaft type flipping structure to realize the rapid switching between the tapping tap 10 and the drill bit 11, and the whole slides horizontally along the cross rail 3, so as to adapt to different tapping positions on the sheet metal parts for tapping operations. Specifically: the motor three 28 starts to drive the rotation of the turning block 30, and the turning block 30 drives the tapping tap 10 and the drill bit 11 on the outer ring side to change positions, so as to complete the seamless connection of the drilling-tapping operation and reduce the disadvantage that the sheet metal parts need to be moved to complete the drilling and tapping;

[0035] Referring to Figure 1 and Figure 7 As shown, a deflection frame 6 is rotatably arranged at the upper end of the base 1, and an adaptive suction clamping component is jointly installed between the upper ends of the deflection frame 6. The adaptive suction clamping component includes a wheel seat 7 rotatably arranged between the deflection frames 6. A push rod seat 13 is jointly installed between the outer edges of the inner side of the wheel seat 7. Magnetic ring seats 12 are slidably installed at both ends of the push rod seat 13. Adsorption magnets 15 are embedded in a pair of magnetic ring seats 12. Support plates 14 are installed on both sides of the push rod seat 13, and a number of flexible support columns 16 are installed on the support plates 14. Among them, the upper end 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 magnet 15;

[0036] Referring to Figure 4 , Figure 5 and Figure 6 As shown, a guide hole 19 is opened in the middle of the push rod seat 13. 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 passing through the guide hole 19 is connected to the magnetic ring seat 12. A double-threaded lead screw 17 is jointly installed between a pair of moving blocks 18. A matching groove 20 matching the upper end of the push rod seat 13 is opened at the lower end of the magnetic ring seat 12 for horizontal sliding limit of the distance adjustment between a pair of magnetic ring seats 12;

[0037] In this process, the adaptive suction clamping component can be adaptively adjusted according to the size specifications of the sheet metal parts to be tapped, and a flexible support is formed by matching the annular electromagnet array with the positioning column structure. The clamping force is adjustable and fits the tapping area, avoiding the problem of deformation at the tapping position caused by uneven force on thin sheet metal parts. Specifically: the rotation of the double-threaded lead screw 17 is controlled by the driving component preset in the wheel seat 7. The driving component can be a conventional driving motor in the prior art. Here, a micro motor is used and marked as motor four. When the motor four starts, it drives the double-threaded lead screw 17 to rotate, and the magnetic adsorption seats 12 on the double-threaded lead screw 17 move in opposite or close directions, so as to adjust the distance between the two groups of adsorption magnets 15 until it adapts to the size of the sheet metal parts to be tapped. Under the combined clamping action of the adsorption magnets 15 distributed in an annular array, the bottom and the outside of the sheet metal parts to be tapped are wrapped and clamped, avoiding the problem of deformation caused by uneven force due to only relying on edge clamping.

[0038] Basic principle: On the one hand, in this embodiment, the integrated drilling and tapping module adopts a rotating shaft type flipping structure to realize the rapid switching of the tapping tap 10 and the drill bit 11, and the whole horizontally slides along the cross rail 3, so as to adapt to different tapping positions on the sheet metal parts 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 parts to be tapped, and a flexible support is formed by the annular electromagnet array in cooperation with the positioning column structure, with adjustable clamping force and fitting the tapping area, avoiding the problem of deformation at the tapping position caused by uneven force on thin sheet metal parts.

[0039] Embodiment 2:

[0040] Regarding the problem that metal chips in the tapping process affect the machining accuracy, the comprehensive collection of metal chips is realized through an adjustable deflection structure combined with a chip suction method of pneumatic suction + gravity sedimentation; referring to Figure 1 - Figure 8 As shown in, a rotating plate 23 is installed inside the lower end of one of the deflection frames 6, a first motor 21 is arranged above the rotating plate 23, the output end of the first motor 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, and the deflection frame 6 axially rotates around the output shaft of the first motor 21 through the arc-shaped rail groove 24. A second motor 22 connected to the wheel seat 7 is installed at the upper end of the deflection frame 6 close to the first motor 21, which is used to control the rotation of the wheel seat 7;

[0041] When performing the tapping operation on the sheet metal part to be tapped, according to the tapping position, the position of the sheet metal part in the adaptive suction clamping component is deflected, so as to complete accurate tapping at different positions. Specifically: the first motor 21 is started, driving the deflection frame 6 to swing, and the deflection frame 6 drives the wheel seat 7 to generate a horizontal offset, so that the vertical corresponding position of the tapping tap 10 or the drill bit 11 undergoes an arc-shaped offset. The fully automatic position adjustment measure is convenient for accurately defining the tapping position and is beneficial to improving the tapping efficiency;

[0042] It can also realize the tapping conversion of the sheet metal parts to be tapped in different adaptive suction clamping components through the rotation control of the wheel seat 7, so as to realize continuous tapping processing and improve the tapping efficiency; specifically: the second motor 22 drives the wheel seat 7 to rotate, and after the tapping of a single sheet metal part to be tapped is completed, it rotates 60° to perform the tapping operation on the next sheet metal part to be tapped;

[0043] Referring to Figure 2 and Figure 8As shown in the figure, a chip removal box 8 is inclined at the lower end between the deflection frames 6. A filter screen 25 is installed in the middle of the chip removal box 8. A suction pipe 9 connected to a pneumatic suction device is installed at the lower end of the chip removal box 8. Rotating rods 27 rotatably connected to the deflection frames 6 are installed at both ends of the chip removal box 8. A suction port 26 is provided in the part of the chip removal box 8 corresponding to the suction pipe 9. It should be noted that during the tapping operation of the sheet metal parts, the metal chips generated during drilling and tapping can fall downward during continuous turning. The suction pipe 9 provided at the bottom of the chip removal box 8 continuously sucks the fine chips, and the filter screen 25 inside the chip removal box 8 can intercept the spiral large chips. Thus, the large chips and the fine chips can be separately sucked and collected, and the entire chip removal box 8 is in an inclined state during the chip collection process, improving the collection efficiency.

[0044] Basic principle: On the one hand, through the deflectable structure design of the adaptive suction and clamping component in this embodiment, rapid position adjustment during drilling and tapping is realized. The fully automatic position adjustment measure facilitates the accurate limitation of the tapping position and improves the tapping efficiency. On the other hand, through the separation and collection method of pneumatic suction + gravity sedimentation, comprehensive suction of metal chips is achieved, avoiding the problem that metal chips affect the processing accuracy.

[0045] Embodiment 3:

[0046] Refer to Figure 1 - Figure 10 As shown in the figure, this embodiment combines the technical contents of Embodiment 1 and Embodiment 2 to propose a tapping method adapted to sheet metal part processing, including the following steps:

[0047] Step 1: The motor four preset in the wheel seat 7 controls the rotation of the double-threaded lead screw 17. When the motor four starts, it drives the double-threaded lead screw 17 to rotate, and the magnetic suction seats 12 on the double-threaded lead screw 17 move in opposite or close directions, thereby adjusting the distance between the two groups of adsorption magnets 15 until it adapts to the size of the sheet metal part to be tapped. Under the cooperative clamping action of the annularly arrayed adsorption magnets 15, the bottom and the outside of the sheet metal part to be tapped are wrapped and clamped, avoiding the problem of deformation caused by uneven stress due to relying only on edge clamping.

[0048] Step 2: The motor three 28 starts to drive the rotation of the turning block 30. The turning block 30 drives the tapping cone 10 and the drill bit 11 on the outer ring side to change positions, thereby achieving seamless connection of the drilling - tapping operation and reducing the drawback that the sheet metal part needs to be moved to complete drilling and tapping.

[0049] Step 3: The motor one 21 starts, driving the deflection frame 6 to swing. The deflection frame 6 drives the wheel seat 7 to generate a horizontal offset, causing an arc-shaped offset of the vertical corresponding position of the tapping cone 10 or the drill bit 11. The fully automatic position adjustment measure facilitates the accurate limitation of the tapping position and is beneficial to improving the tapping efficiency.

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

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

[0052] In summary, on the one hand, the present invention realizes the rapid switching of the tapping cone 10 and the drill bit 11 through the integrated drilling and tapping module adopting a rotating shaft type flipping structure, and the whole horizontally slides along the cross rail 3, so as to adapt to different tapping positions on the sheet metal part for tapping operations; on the other hand, the adaptive suction clamping assembly can be adaptively adjusted according to the size specifications of the sheet metal part to be tapped, and a flexible support is formed by matching the annular electromagnet array with the positioning post structure. The clamping force is adjustable and fits the tapping area, avoiding the problem of deformation at the tapping position caused by uneven stress on thin sheet metal parts;

[0053] Moreover, through the deflectable structure design of the adaptive suction clamping assembly, the rapid position adjustment during the drilling and tapping process can be realized. The fully automatic position adjustment measure is convenient for accurately defining the tapping position and improving the tapping efficiency; and the comprehensive suction removal of metal chips is realized by combining the separation and collection method of pneumatic suction + gravity sedimentation, avoiding the problem that metal chips affect the processing accuracy.
