Description

Technical Field

[0001] This invention relates to the field of tapping machine technology, and in particular to a high-precision AI intelligent positioning tapping machine. Background Technology

[0002] Tapping is a crucial step in sheet metal fabrication. It involves using a specific torque to screw a tap into a pre-drilled hole to create an internal thread. Tapping machines are the primary equipment for sheet metal tapping, and they can be categorized into manual, semi-automatic, and fully automatic tapping machines based on their level of automation.

[0008] As a further aspect of the present invention: the tool holder has a through-hole for the tapping tool to pass through, and the tool holder has an installation groove and a rotating groove at both ends. The top of the rotating groove has a plurality of radial sliding grooves evenly arranged around the clamping hole. A radial slider is adapted to be slidably installed in each radial sliding groove. A first pulley is rotatably installed in the installation groove, and a second pulley is rotatably installed in the rotating groove. A transmission belt is provided between the first pulley and the second pulley. The output end of the clamping motor is fixedly connected to the first pulley. A turntable is fixedly installed at the top of the second pulley. The turntable drives the radial slider to realize the radial clamping action.

[0009] As a further embodiment of the present invention: a clamping block is fixedly provided at the front end of the radial slider, the clamping block passes through the tool clamping member and extends into the clamping hole, the tail end of the radial slider is connected to the radial slide groove through a reset spring, a limit pin is fixedly provided at the bottom of the radial slider, and a plurality of oblique grooves are uniformly provided circumferentially on the turntable, and the limit pin is adapted to slide and install in the corresponding oblique groove.

[0010] As a further aspect of the present invention: the tapping tool includes a tool body, a connecting seat is provided at the top of the tool body, the output end of the tapping tool is connected to the connecting seat, a rotating sleeve is rotatably installed on the outer side of the tool body, the clamping block is clamped and abutted against the outer wall of the rotating sleeve, and a cutting head is provided at the bottom of the tool body.

[0011] As a further aspect of the present invention: one end of the mounting bracket is respectively provided with an oil injection pipe and an air jet pipe, and both the oil injection pipe and the air jet pipe are oriented toward the tapping tool.

[0012] As a further embodiment of the present invention: the linear motion pair includes a drive motor and a pair of mating gears. The output end of the drive motor is connected to one of the mating gears. A gear belt is provided between the two mating gears. A lifting frame is fixedly provided on the gear belt. A mounting base is slidably mounted on one side of the lifting frame. Imaging devices are fixedly provided on both sides of the mounting base.

[0013] As a further aspect of the present invention: the loading and unloading assembly includes a pair of suction cup cylinders, the suction cup cylinders are fixedly mounted at both ends of the mounting bracket, the output end of the suction cup cylinders is fixedly connected to a suction cup mounting plate, and a vacuum suction cup is fixedly mounted on the suction cup mounting plate.

[0014] The beneficial effects of this invention are:

[0015] (1) Sheet metal parts are placed on the pneumatic suction cup at the top of the workbench by the loading and unloading assembly for adsorption and fixation. During the tapping process, the movable seat is moved laterally and longitudinally along the horizontal and vertical guide rails respectively by the back-end control center, so that the tapping tool is aligned with the tapping hole on the sheet metal part. The tapping motor drives the tapping tool to rotate, and then the lifting cylinder drives the tapping tool to gradually feed downward until it is close to the sheet metal part and the tapping process is carried out. When the tool needs to be changed, the displacement motor drives the displacement gear to rotate, so that the mounting bracket moves horizontally and linearly relative to the base plate until the tool magazine moves to the bottom of the tool changing assembly. The rotary motor drives the tool magazine to rotate, and the tool changing assembly selects the appropriate tapping tool from the tool magazine and clamps it. The whole process does not require manual intervention and can realize the integrated automated tapping process of loading, positioning, tapping, tool changing and unloading. The degree of automation is high, which greatly improves the efficiency and accuracy of sheet metal tapping.

[0016] (2) By setting up a tool clamping component, during the tool changing process, the tapping tool to be replaced is coaxially inserted into the clamping hole. At this time, the clamping motor drives the first pulley to rotate, and the first pulley drives the second pulley to rotate through the transmission belt. The second pulley will drive the turntable to rotate synchronously. When the turntable rotates, it will drive multiple sets of radial sliders to slide synchronously along the radial groove by utilizing the sliding cooperation between the inclined groove and the limit pin until the clamping block extends and abuts against the tapping tool, thereby realizing the clamping and positioning of the tool. Moreover, the radial clamping movement of multiple sets of clamping blocks is kept synchronous and the feed amount is the same, which can realize the coaxial centering clamping process for different tapping tools. The tapping center of any tapping tool is kept on the same axis, which is beneficial to improve the tapping accuracy. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-4As shown, this invention is a high-precision AI intelligent positioning tapping machine, including a worktable 1. A frame 101 is fixedly mounted on both sides of the worktable 1. Support frames 102 are fixedly mounted on both sides of the frame 101. A linear motion pair 2 is mounted on the upper end of the support frame 102. A longitudinal guide rail 3 is fixedly mounted on the upper end of the frame 101. A transverse guide rail 4 is slidably mounted on the longitudinal guide rail 3. Multiple pneumatic suction cups 5 are arranged on the upper end of the worktable 1. A base plate 7 is slidably mounted on the transverse guide rail 4 along its length. A lifting guide rail 701 is fixedly mounted at the front end of the base plate 7. A movable seat 8 is slidably mounted on the lifting guide rail 701. The movable seat 8 is driven by a lifting cylinder 9 to slide up and down along the lifting guide rail 701. A tapping motor 13 is fixedly mounted on the movable seat 8. A tool changing assembly is provided on one side of the base plate 7. A fixed base 14 is fixedly provided at the rear end of the base plate 7. A mounting bracket 15 is provided below the fixed base 14. Limiting slide rails 16 are provided on both sides of the upper end of the mounting bracket 15. The bottom of the fixed base 14 is slidably mounted on the limiting slide rails 16 via a slider. A toothed plate 21 is fixedly provided on the upper end of the mounting bracket 15 along the length direction. A displacement motor 19 is fixedly provided on the fixed base 14. A displacement gear 20 is connected to the output end of the displacement motor 19. The displacement gear 20 meshes with the toothed plate 21. A rotary motor 17 is fixedly provided at the bottom of the mounting bracket 15. A tool magazine 18 is connected to the output end of the rotary motor 17. Several tapping tools 25 are evenly installed in the circumferential direction in the tool magazine 18. A loading and unloading assembly is provided at one end of the mounting bracket 15.

[0031] Specifically, the sheet metal parts are placed onto the pneumatic suction cup 5 at the top of the worktable 1 by the loading and unloading assembly for adsorption and fixation. During the tapping process, the movable seat 8 moves laterally and longitudinally along the horizontal guide rail 4 and the vertical guide rail 3 respectively through the back-end control center, thereby aligning the tapping tool 25 with the tapping hole on the sheet metal parts. The tapping motor 13 drives the tapping tool 25 to rotate, and then the lifting cylinder 9 drives the tapping tool 25 to gradually feed downwards until it approaches the sheet metal parts and performs the tapping process. When it is necessary to change the tool, the displacement motor 19 drives the displacement gear 20 to rotate, thereby causing the mounting bracket 15 to move horizontally and linearly relative to the base plate 7 until the tool magazine 18 moves below the tool changing assembly. The rotary motor 17 drives the tool magazine 18 to rotate, and the tool changing assembly selects the appropriate tapping tool 25 from the tool magazine 18 and clamps it. The whole process does not require manual intervention and can realize an integrated automated tapping process of loading, positioning, tapping, tool changing and unloading. The degree of automation is high, which greatly improves the efficiency and accuracy of sheet metal tapping.

[0032] like Figure 5 As shown, the tool changing assembly includes a tool changing cylinder 10, which is fixedly mounted on a cylinder seat. The cylinder seat is fixedly connected to the movable seat 8. A motor seat is fixedly connected to the output end of the tool changing cylinder 10. A clamping motor 11 is fixedly mounted on one side of the motor seat. The bottom of the motor seat is fixedly connected to the tool clamping component 12.

[0033] Specifically, during the tool changing process, the tool magazine 18 first moves along the limiting slide rail 16 to below the tapping motor 13, and rotates the appropriate tapping tool 25 to the clamping position via the rotary motor 17. The tool changing cylinder 10 pushes the tool holder 12 downward to the clamping position, and then the clamping motor 11 clamps and positions the tapping tool 25 at the position. The tool changing cylinder 10 then pulls the tool holder 12 upward, thereby disengaging the tapping tool 25 from the tool magazine 18. The tool changing holder continues to move upward until the output end of the tapping motor 13 clamps the top of the tapping tool 25. Then, the tool magazine 18 retracts along the limiting slide rail 16 in the opposite direction, providing sufficient feed space for the subsequent tapping process.

[0034] like Figure 6 and Figure 10 As shown, the tool holder 12 has a through-hole 1201 for the tapping tool 25 to pass through. The tool holder 12 has an installation groove 1202 and a rotating groove 1203 at both ends. The top of the rotating groove 1203 has several radial grooves 1204 evenly arranged around the clamping hole 1201. Each radial groove 1204 is fitted with a radial slider 124. A first pulley 121 is rotatably installed in the installation groove 1202. A second pulley 122 is rotatably installed in the rotating groove 1203. A transmission belt is provided 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. A turntable 123 is fixedly installed at the top of the second pulley 122. The turntable 123 drives the radial slider 124 to achieve radial clamping action.

[0035] like Figure 9 and Figure 10 As shown, a clamping block 1241 is fixedly installed at the front end of the radial slider 124. The clamping block 1241 passes through the tool clamping member 12 and extends into the clamping hole 1201. The tail end of the radial slider 124 is connected to the radial slide groove 1204 through the return spring 1242. A limit pin 1243 is fixedly installed at the bottom of the radial slider 124. Several inclined grooves 1231 are evenly provided around the turntable 123. The limit pin 1243 is adapted to slide and install in the corresponding inclined groove 1231.

[0036] Specifically, by setting up the tool clamping component 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. The first pulley 121 drives the second pulley 122 to rotate through the transmission belt. The second pulley 122 drives the turntable 123 to rotate synchronously. When the turntable 123 rotates, it uses the sliding cooperation between the inclined groove 1231 and the limiting pin 1243 to drive multiple sets of radial sliders 124 to slide synchronously along the radial groove 1204 until the clamping block 1241 extends out and abuts against the tapping tool 25, thereby achieving clamping and positioning of the tool. Moreover, the radial clamping movement of multiple sets of clamping blocks 1241 is synchronized and the feed is the same, which can achieve coaxial centering clamping process for different tapping tools 25. The tapping center of any tapping tool 25 is kept on the same axis, which is beneficial to improving tapping accuracy.

[0037] like Figure 7 and Figure 8 As shown, the tapping tool 25 includes a tool body 2501, a connecting seat 2502 is provided 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 outside of the tool body 2501, a clamping block 1241 is clamped and abutted against the outer wall of the rotating sleeve 2503, and a cutting head 2504 is provided at the bottom of the tool body 2501.

[0038] Specifically, the tapping tool 25 is quickly assembled and connected to the output shaft of the tapping motor 13 via the connecting seat 2502. When clamped, the clamping block 1241 clamps and fixes the outer rotating sleeve 2503, while the inner tool body 2501 can rotate freely within the rotating sleeve 2503 without being affected by the clamping action. Thus, the tapping motor 13 can drive the bottom cutter head 2504 to rotate at high speed to achieve tapping. During the tapping process, the tool body 2501 will always be constrained to rotate within the rotating sleeve 2503, ensuring that the cutter head 2504 will not wobble, which is beneficial to improving the tapping stability.

[0039] like Figure 3 As shown, one end of the mounting bracket 15 is respectively provided with an oil injection pipe 151 and an air jet pipe 152, both of which are oriented toward the tapping tool.

[0040] Specifically, when tapping sheet metal parts with high requirements, the oil spray pipe 151 will spray volatile grease, which helps to reduce friction and tapping resistance during the tapping process, reduce tap wear, and also reduce jamming during tapping, maintaining the continuity of the operation. The volatile grease also carries away some heat during evaporation, preventing overheating and damage to the tapping tool 25. The air spray pipe 152 can blow away the chips generated during the tapping process, preventing chip accumulation in the tapped hole, which affects tapping quality and accuracy. Blowing away chips also reduces wear on the tapping tool 25. Furthermore, during sheet metal tapping, the friction temperature locally increases; the air spray also carries away some of this heat, preventing excessively high temperatures that could adversely affect the operation and the tool.

[0041] like Figure 1 and Figure 2 As shown, the linear motion pair 2 includes a drive motor 201 and a pair of mating gears 202. The output end of the drive motor 201 is connected to one of the mating gears 202. A gear belt 203 is provided between the two mating gears 202. A lifting frame 6 is fixedly installed on the gear belt 203. A mounting base 601 is slidably installed on one side of the lifting frame 6. Imaging devices 602 are fixedly installed on both sides of the mounting base 601. A lighting device 603 is fixedly installed at the bottom of the mounting base 601.

[0042] 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 up to take pictures. After multiple shots are taken and the images are combined, the back-end control center performs AI intelligent analysis based on the image information (including analysis of the tapping hole size, hole spacing measurement, and automatic path analysis, etc.), and automatically programs the movement path to select the optimal working route, thereby optimizing the travel route and reducing the frequency of tool changes, saving the entire tapping operation time and improving tapping efficiency. When the brightness of the imaging device 602 is insufficient and affects the imaging effect, the lighting device 603 can be turned on to supplement the light.

[0043] like Figure 4 As shown, the loading and unloading assembly includes a pair of suction cup cylinders 22. The suction cup cylinders 22 are fixedly installed at both ends of the mounting bracket 15. The output end of the suction cup cylinders 22 is fixedly connected to a suction cup mounting plate 23. A vacuum suction cup 24 is fixedly installed on the suction cup mounting plate 23.

[0044] As an alternative to this application, the loading and unloading assembly uses a gripping robot to grip sheet metal for loading and unloading, achieving the same effect.

[0045] The working principle of this invention is as follows: Figures 1-10As shown, during use, the sheet metal parts are placed on the pneumatic suction cup 5 at the top of the worktable 1 by the loading and unloading assembly for adsorption and fixation. During the tapping process, the movable seat 8 achieves lateral and longitudinal displacement along the transverse guide rail 4 and the longitudinal guide rail 3 respectively through the background control center, thereby aligning the tapping tool 25 with the tapping hole on the sheet metal parts. The tapping motor 13 drives the tapping tool 25 to rotate, and then the lifting cylinder 9 drives the tapping tool 25 to gradually feed downwards until it approaches the sheet metal parts and performs the tapping process. When a tool change is required, the displacement motor 19 drives the displacement gear 20 to rotate, causing the mounting bracket 15 to move horizontally relative to the base plate 7 until the tool magazine 18 moves below the tool changing assembly. The rotary motor 17 then rotates the appropriate tapping tool 25 to the clamping position. The tool changing cylinder 10 pushes the tool holder 12 downwards to the clamping position, and the clamping motor 11 clamps and positions the tapping tool 25 at this position. The tool changing cylinder 10 then pulls the tool holder 12 upwards, disengaging the tapping tool 25 from the tool magazine 18. The tool changing holder continues to move upwards until the output end of the tapping motor 13 clamps the top of the tapping tool 25. The tool magazine 18 then retracts along the limit slide rail 16, providing sufficient feed space for the subsequent tapping process. The entire process requires no manual intervention, achieving an integrated automated tapping process encompassing loading, positioning, tapping, tool changing, and unloading. This high degree of automation significantly improves the efficiency and accuracy of sheet metal tapping.

[0046] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
