Description

Technical Field

[0001] This utility model relates to the field of automated machining equipment, and in particular to a multi-head tapping mechanism. Background Technology

[0002] Tapping machines, as specialized equipment for machining internal threads on workpieces, are widely used in various industrial fields such as machinery manufacturing, automotive parts processing, electronic device production, and hardware product processing due to their advantages such as high processing efficiency and stable thread accuracy.

[0003] However, most tapping machines on the market currently adopt a single-blade structure design, meaning that each machine is equipped with only one tapping spindle and corresponding tapping tool. When dealing with workpieces that need to be machined with multiple threaded holes, this type of single-blade tapping machine can only adopt a one-by-one tapping processing mode. This processing mode has low processing efficiency and is difficult to match the high-speed production rhythm of modern production lines. Furthermore, because one-by-one tapping requires multiple manual or mechanical switching of processing stations, it is prone to defects such as missed taps or tapping position deviations due to positioning errors, affecting product quality. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A multi-head tapping mechanism includes a machine base, a multi-head tapping head, and a wire breakage detection device. The machine base is equipped with a support seat that can reciprocate on a horizontal plane. The support seat has a tapping area and a detection area. The multi-head tapping head includes a machining seat, which is located above the support seat and can move vertically relative to the support seat. Multiple cutter shafts are rotatably mounted on the bottom of the machining seat, and each cutter shaft is equipped with a tap. The machining seat is equipped with a transmission component for driving each cutter shaft to rotate in the same direction. A drive motor is located on the top of the machining seat and is connected to the transmission component. The wire breakage detection device includes a detection seat, which is located on the detection area. The detection seat has multiple detection units, the number of which is the same as the number of taps, and each detection unit corresponds to one tap.

[0006] As a further embodiment of this utility model: multiple cutter shafts are arranged in a row and multiple columns. The transmission assembly includes a drive gear, a transmission gear, and a cutter shaft gear. The drive gear, transmission gear, and cutter shaft gear are all helical gears. The number of cutter shaft gears is the same as the number of cutter shafts, and each cutter shaft gear corresponds one-to-one with each cutter shaft. Each cutter shaft gear is respectively set on its corresponding cutter shaft. The number of transmission gears is one less than the number of cutter shaft gears. Any two adjacent cutter shaft gears are meshed and driven by a transmission gear. There is one drive gear, which meshes with one of the transmission gears and is coaxially connected to the output shaft of the drive motor.

[0007] As a further embodiment of this utility model: multiple cutter shafts are arranged in two rows and multiple columns. The transmission assembly includes a driving gear, a transmission gear, a driven gear, and a cutter shaft gear. The driving gear, transmission gear, driven gear, and cutter shaft gear are all helical gears. The number of cutter shaft gears is the same as the number of cutter shafts. The multiple cutter shaft gears are divided into two rows, with the two rows of cutter shaft gears corresponding to the two rows of cutter shafts. Each cutter shaft gear is respectively set on its corresponding cutter shaft. The number of transmission gears is two fewer than the number of cutter shaft gears. Any two adjacent cutter shaft gears in the same row are meshed and driven by a transmission gear. There is one driving gear, which is set between the two rows of cutter shaft gears and coaxially connected to the output shaft of the drive motor. There are two driven gears, and one of the cutter shaft gears in the same row is meshed and driven by a driven gear.

[0008] As a further embodiment of this utility model: the bottom of the machining base is provided with a mounting block, and a through hole extending laterally is provided on the mounting block. An oil inlet pipe is inserted through the through hole. Multiple mounting holes are provided on the side of the mounting block near the cutter shaft. The number of mounting holes is the same as the number of cutter shafts. An oil outlet pipe communicating with the oil inlet pipe is inserted into each mounting hole. Each oil outlet pipe is directed toward each tap.

[0009] As a further embodiment of this utility model: the detection unit is a tool setter, model GZ-36.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the setting of transmission components and multiple cutter shafts, can realize the synchronous processing of multiple threaded holes, adapt to the high-speed continuous production rhythm, and ensure production efficiency.

[0012] 2. With the addition of a broken tap detection device, the condition of each tap can be independently detected, accurately identifying abnormalities such as tap breakage. This allows for immediate detection of abnormalities and the shutdown or alarm to be triggered, preventing ineffective machining problems such as unmachined or incomplete machining due to the breakage of a single tool.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-7In this embodiment of the present invention, a multi-head tapping mechanism includes a machine base 1, a multi-head tapping head, and a wire breakage detection device. The machine base 1 is provided with a support seat 2 that can reciprocate on a horizontal plane. The support seat 2 is provided with a tapping area 4 and a detection area 3. The multi-head tapping head includes a processing seat 5, which is located above the support seat 2 and can move vertically relative to the support seat 2. Multiple cutter shafts 6 are rotatably arranged at the bottom of the processing seat 5, and each cutter shaft 6 is provided with a tap 7. The processing seat 5 is provided with a transmission component 8 for driving each cutter shaft 6 to rotate in the same direction. The top of the processing seat 5 is provided with a drive motor 9, which is connected to the transmission component 8. The wire breakage detection device includes a detection seat 10, which is located on the detection area 3. The detection seat 10 is provided with multiple detection units 11, the number of which is the same as the number of taps 7, and each detection unit 11 corresponds to each tap 7.

[0025] It should be noted that by setting two sets of lead screw drive assemblies on the machine tool 1, the two sets of lead screw drive assemblies are used to drive the bearing seat 2 and the machining seat 5 to move in a preset direction respectively. During processing, the operator first places the product on the tapping area 4, and then the bearing seat 2 drives the product to move below the machining seat 5. Then the machining seat 5 moves down vertically so that each tap 7 is close to the product's thread hole processing position. The drive motor 9 starts and drives all taps 7 to rotate in the same direction through the transmission assembly 8, thereby performing synchronous tapping processing on multiple thread holes on the product. After the thread holes are processed, the machining seat 5 moves up vertically to reset, and the bearing seat 2 drives the detection seat 10 to move below the machining seat 5. Then the machining seat 5 moves down so that each tap 7 contacts each detection unit 11, and the status of each tap 7 is independently detected. If any detection unit 11 detects an abnormality such as a broken tap 7, it sends a signal to stop the machine or alarms to prompt the operator to troubleshoot the fault, avoiding invalid processing problems such as some thread holes not being processed or incomplete processing due to the breakage of a single tool.

[0026] The tool shaft 6 arrangement and transmission assembly 8 of this utility model have two implementation methods. For the first implementation method, please refer to [link to implementation method]. Figure 3Multiple cutter shafts 6 are arranged in a row and multiple columns. The transmission assembly 8 includes a drive gear 12, a transmission gear 13, and a cutter shaft gear 14. The drive gear 12, transmission gear 13, and cutter shaft gear 14 are all helical gears. The number of cutter shaft gears 14 is the same as the number of cutter shafts 6, and each cutter shaft gear 14 corresponds one-to-one with each cutter shaft 6. Each cutter shaft gear 14 is respectively set on the corresponding cutter shaft 6. The number of transmission gears 13 is one less than the number of cutter shaft gears 14. Any two adjacent cutter shaft gears 14 are meshed and driven by one transmission gear 13. There is one drive gear 12. The drive gear 12 meshes with one of the transmission gears 13 and is coaxially connected to the output shaft of the drive motor 9. During processing, the drive motor 9 drives the coaxially connected drive gear 12 to rotate. The drive gear 12 drives the transmission gear 13 that it meshes with to rotate. The transmission gear 13 then drives the remaining transmission gears 13 and all the cutter shaft gears 14 to rotate in sequence. Since the adjacent cutter shaft gears 14 are indirectly meshed through the transmission gear 13, the rotation direction of each cutter shaft gear 14 is consistent. Finally, the taps 7 on each cutter shaft 6 are driven to rotate in the same direction, thereby synchronously tapping a row of threaded holes on the product.

[0027] For a second embodiment of the arrangement of the cutter shaft 6 and the transmission assembly 8, please refer to [link / reference]. Figure 4 Multiple cutter shafts 6 are arranged in two rows and multiple columns. The transmission assembly 8 includes a driving gear 12, a transmission gear 13, a driven gear 15, and a cutter shaft gear 14. The driving gear 12, transmission gear 13, driven gear 15, and cutter shaft gear 14 are all helical gears. The number of cutter shaft gears 14 is the same as the number of cutter shafts 6. The multiple cutter shaft gears 14 are divided into two rows, and the two rows of cutter shaft gears 14 correspond to the two rows of cutter shafts 6. Each cutter shaft gear 14 is respectively set on the corresponding cutter shaft 6. The number of transmission gears 13 is two less than the number of cutter shaft gears 14. Any two adjacent cutter shaft gears 14 in the same row are meshed and driven by one transmission gear 13. There is one driving gear 12, which is set between the two rows of cutter shaft gears 14 and is coaxially connected to the output shaft of the drive motor 9. There are two driven gears 15, and one of the cutter shaft gears 14 in the same row is meshed and driven by one driven gear 15. During processing, the drive motor 9 drives the coaxially connected drive gear 12 to rotate. The drive gear 12 simultaneously drives two driven gears 15 to rotate through meshing. The two driven gears 15 transmit power to the corresponding cutter shaft gears 14. Under the transmission of the transmission gear 13, the two rows of cutter shaft gears 14 rotate. Since the adjacent cutter shaft gears 14 in the same row are indirectly meshed through the transmission gear 13, and the two rows of cutter shaft gears 14 maintain the same direction of rotation through the meshing relationship between the drive gear 12 and the driven gears 15, they ultimately drive all the taps 7 on the two rows of cutter shafts 6 to rotate in the same direction, thereby synchronously tapping the two rows of threaded holes on the product.

[0028] It should be noted that the driving gear 12, transmission gear 13, driven gear 15, and cutter shaft gear 14 are all helical gears. Compared to spur gears, helical gears have less meshing impact, resulting in significantly reduced transmission vibration and noise.

[0029] The bottom of the machining base 5 is provided with a mounting block 16. A through hole 17 extending laterally is provided on the mounting block 16, through which an oil inlet pipe 18 passes. Multiple mounting holes 19 are provided on the side of the mounting block 16 near the cutter shaft 6, the number of which is the same as the number of cutter shafts 6. Each mounting hole 19 has an oil outlet pipe 20 communicating with the oil inlet pipe 18, and each oil outlet pipe 20 faces its respective tap 7. During machining, each oil outlet pipe 20 continuously supplies lubricating medium to its corresponding tap 7, effectively reducing cutting friction between the tap 7 and the workpiece, thereby significantly improving the service life of the tap 7.

[0030] The detection unit 11 is a tool setter, model GZ-36. As a professional tool condition detection device, the tool setter can accurately detect the breakage of tap 7. After machining, the machining seat 5 moves down to bring each tap 7 into contact with the corresponding tool setter, and the tool setter can quickly complete the independent detection of multiple taps 7.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
