[0029] Specifically, the sheet metal is placed on the pneumatic suction cup 5 at the upper end of the workbench 1 through the loading and unloading assembly for adsorption and fixation. During the tapping process, the movable seat 8 realizes lateral displacement and longitudinal displacement along the lateral guide rail 4 and the longitudinal guide rail 3 respectively through the background control center, so that the tapping tool 25 is aligned with the tapping hole on the sheet metal, and the tapping tool 25 is driven to rotate by the tapping motor 13, and then the lifting cylinder 9 is used to drive the tapping tool 25 to gradually feed downward until it approaches the sheet metal and performs the tapping process. When the tool needs to be replaced, the displacement motor 19 drives the displacement gear 20 to rotate, so that the mounting bracket 15 as a whole moves horizontally and linearly relative to the base plate 7 until the tool magazine 18 moves to the bottom of the tool replacement assembly, and the rotating motor 17 is used to drive the tool magazine 18 to rotate, and the tool replacement assembly selects a suitable tapping tool 25 from the tool magazine 18 and clamps it. The whole process does not require human intervention, and can realize an integrated automated tapping process of loading, positioning, tapping, tool changing and unloading, with a high degree of automation, which greatly improves the efficiency and accuracy of sheet metal tapping.

[0030] like Figure 5 As shown, the tool changing assembly includes a tool changing cylinder 10, which is fixedly arranged on a cylinder seat, and the cylinder seat is fixedly connected to a movable seat 8. An output end of the tool changing cylinder 10 is fixedly connected to a motor seat, and a clamping motor 11 is fixedly arranged on one side of the motor seat, and the bottom of the motor seat is fixedly connected to a tool clamping member 12.

[0031] Specifically, during the tool changing process, the tool magazine 18 first moves along the limit slide 16 to the bottom of the tapping motor 13, and rotates the appropriate tapping tool 25 to the clamping station through the rotating motor 17, and uses the tool changing cylinder 10 to push the tool clamping member 12 downward to the clamping station, and then the clamping motor 11 clamps and positions the tapping tool 25 on the station, and then pulls the tool clamping member 12 upward through the tool changing cylinder 10, so that the tapping tool 25 is detached from the tool magazine 18, and the tool changing clamping member continues to move upward until the output end of the tapping motor 13 is clamped with the top of the tapping tool 25, and then the tool magazine 18 retreats in the opposite direction along the limit slide 16 to make enough feeding space for the next tapping process.

[0032] like Figure 6 and Fig.10 As shown, the tool holder 12 is penetrated by a clamping hole 1201 for the threading tool 25 to pass through, and an installation groove 1202 and a rotating groove 1203 are respectively provided at both ends inside the tool holder 12, and a plurality of radial slide grooves 1204 are evenly arranged around the clamping hole 1201 at the top of the rotating groove 1203, and a radial slider 124 is slidably installed in each radial slide groove 1204, a first pulley 121 is rotatably installed in the installation groove 1202, and a second pulley 122 is rotatably installed in the rotating groove 1203, a transmission belt is arranged between the first pulley 121 and the second pulley 122, the output end of the clamping motor 11 is fixedly connected to the first pulley 121, and a turntable 123 is fixedly arranged on the top of the second pulley 122, and the turntable 123 drives the radial slider 124 to realize the radial clamping action.

[0033] like Fig. 9 and Fig.10 As shown, a clamping block 1241 is fixedly provided at the front end of the radial slider 124, the clamping block 1241 passes through the tool clamping piece 12 and extends into the clamping hole 1201, the rear end of the radial slider 124 is connected to the radial slide groove 1204 through a reset spring 1242, a limiting pin 1243 is fixedly provided at the bottom of the radial slider 124, and a plurality of oblique grooves 1231 are evenly arranged circumferentially on the turntable 123, and the limiting pins 1243 are adapted to be slidably installed in the corresponding oblique grooves 1231.

[0034] Specifically, by setting the tool clamping part 12, during the tool changing process, the tapping tool 25 to be replaced is coaxially inserted into the clamping hole 1201. At this time, the clamping motor 11 drives the first pulley 121 to rotate, and the first pulley 121 drives the second pulley 122 to rotate through the transmission belt, and the second pulley 122 will drive the turntable 123 to rotate synchronously. When the turntable 123 rotates, the sliding cooperation between the oblique groove 1231 and the limit pin 1243 will drive multiple groups of radial sliders 124 to slide synchronously along the radial slide groove 1204 until the clamping block 1241 extends out and abuts against the tapping tool 25, thereby realizing the clamping and positioning of the tool, and the radial clamping movements of the multiple groups of clamping blocks 1241 are kept synchronous and the feed amount is the same, so that the coaxial centering clamping process can be realized for different tapping tools 25, and the tapping center of any tapping tool 25 is kept on the same axis, which is beneficial to improving the tapping accuracy.

[0035] like Figure 7 and Figure 8 As shown, the tapping tool 25 includes a tool body 2501, a connecting seat 2502 is arranged at the top of the tool body 2501, the output end of the tapping tool 25 is connected to the connecting seat 2502, a rotating sleeve 2503 is rotatably installed on the outer side of the tool body 2501, the clamping block 1241 is clamped against the outer wall of the rotating sleeve 2503, and a tool head 2504 is arranged at the bottom end of the tool body 2501.

[0036] Specifically, the tapping tool 25 is quickly assembled and connected with the output shaft of the tapping motor 13 through the connecting seat 2502. When clamping, the clamping block 1241 will clamp and fix the external rotating sleeve 2503, while the internal tool body 2501 can rotate freely in the rotating sleeve 2503 without being affected by the clamping effect, so that the tapping motor 13 can drive the bottom cutter head 2504 to rotate at high speed to achieve tapping, and during the tapping process, the tool body 2501 will always be constrained to rotate in the rotating sleeve 2503, ensuring that the cutter head 2504 will not shake, which is beneficial to improving the tapping stability.

[0037] like Figure 3 As shown, an oil injection pipe 151 and an air jet pipe 152 are respectively provided at one end of the mounting bracket 15, and both the oil injection pipe 151 and the air jet pipe 152 are arranged toward the tapping edge.

[0038] Specifically, when tapping some sheet metal parts with higher requirements, the oil spray pipe 151 will spray volatile grease, which helps to reduce friction, tapping resistance, and tap wear during tapping. It can also reduce the jamming phenomenon during tapping and maintain the continuity of the operation. At the same time, the volatile grease can also take away some heat during the volatilization process to avoid excessive temperature and damage to the tapping tool 25. The air jet pipe 152 can blow away the chips brought by the tapping process to avoid the accumulation of chips in the tapping hole, which affects the tapping quality and accuracy. Blowing away the chips can also reduce the wear of the tapping tool 25. At the same time, the friction temperature will rise locally during the sheet metal tapping process, and the blowing can also take away some heat to avoid the temperature being high enough to have an adverse effect on the operation and the tool.

[0039] like Figure 1 and Figure 2 As shown, the linear motion pair 2 includes a driving motor 201 and a pair of matching gears 202. The output end of the driving motor 201 is connected to one of the matching gears 202. A gear belt 203 is arranged between the two matching gears 202. A lifting frame 6 is fixedly arranged on the gear belt 203. A mounting seat 601 is mounted on one side of the lifting frame 6 for sliding up and down. Imaging devices 602 are fixedly arranged on both sides of the mounting seat 601. A lighting device 603 is fixedly arranged on the bottom of the mounting seat 601.

[0040] Specifically, the imaging device 602 is an industrial camera. Depending on the size of the tapping object, two or more industrial cameras can be set to take pictures. After multiple shots and grouping, the background control center performs AI intelligent analysis based on the image information (including tapping hole size analysis, hole distance measurement, and path automatic analysis, etc.), and automatically programs the moving path and selects the best working route to optimize the walking route and reduce the frequency of tool replacement, saving the entire tapping operation time and improving the tapping efficiency. When the imaging device 602 is not bright enough during imaging, affecting the imaging effect, the lighting device 603 can be turned on for fill light.

[0041] like Figure 4 As shown, the loading and unloading assembly has a pair of suction cup cylinders 22, which are fixedly arranged at both ends of the mounting bracket 15, and the output end of the suction cup cylinder 22 is fixedly connected to a suction cup mounting plate 23, on which a vacuum suction cup 24 is fixedly arranged.

[0042] As another alternative solution of the present application, the loading and unloading assembly adopts a grasping robot to grasp the sheet metal loading and unloading, which can achieve the same effect.

[0043] The working principle of the present invention is as follows: Figure 1-Figure 10As shown, when in use, the sheet metal is placed on the pneumatic suction cup 5 at the upper end of the workbench 1 through the loading and unloading components for adsorption and fixation. During the tapping process, the movable seat 8 realizes lateral displacement and longitudinal displacement along the lateral guide rail 4 and the longitudinal guide rail 3 respectively through the background control center, so that the tapping tool 25 is aligned with the tapping hole on the sheet metal. The tapping tool 25 is driven to rotate by the tapping motor 13, and then the lifting cylinder 9 is used to drive the tapping tool 25 to gradually feed downward until it is close to the sheet metal and the tapping process is performed. When the tool needs to be replaced, the displacement motor 19 drives the displacement gear 20 to rotate, so that the mounting bracket 15 as a whole moves horizontally and linearly relative to the base plate 7 until the tool magazine 18 moves to the bottom of the tool replacement assembly, and the appropriate tapping tool 25 is rotated to the clamping station by the rotating motor 17, and the tool change cylinder 10 is used to push the tool clamp 12 downward to the clamping station, and then the clamping motor 11 clamps and positions the tapping tool 25 on the station, and then the tool change cylinder 10 pulls the tool clamp 12 upward, so that the tapping tool 25 is separated from the tool magazine 18, and the tool change clamp continues to move upward until the output end of the tapping motor 13 is clamped with the top of the tapping tool 25, and then the tool magazine 18 is reversed along the limit slide rail 16 to make enough feeding space for the next tapping process. The whole process does not require human participation, and can realize the integrated automated tapping process of loading, positioning, tapping, tool changing and unloading, with a high degree of automation, which greatly improves the efficiency and accuracy of sheet metal tapping.

[0044] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
