Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a multi-functional multi-axis device for drilling and wire winding. Background Technology

[0002] Many products manufactured today require drilling and wire reeling. Because of the differences in products, the number of holes and the spacing between them vary. Drilling one hole at a time is inefficient and time-consuming. Therefore, a multi-spindle drill that can drill multiple holes simultaneously and whose hole positions can be adjusted is needed. Summary of the Invention

[0003] In view of the above, it is necessary to provide a multi-functional multi-spindle drill for drilling and wire reeling, which can drill multiple holes or reel wire simultaneously and has adjustable hole positions.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A multi-functional multi-spindle drilling and wire reeling device mainly includes a fixed frame and a connecting plate. The fixed frame mainly includes a fixed plate and supports. Multiple supports are arranged around the outer edge of the fixed plate, and the lower ends of the supports are mounted on the ring frame. The connecting plate is fixed to the fixed plate by multiple studs. Multiple connecting holes are provided on the connecting plate, and the studs are inserted into the connecting holes. Upper and lower nuts are threaded onto the studs, respectively abutting against the upper and lower end faces of the connecting plate to fix the connecting plate above the fixed plate. The upper end face of the connecting plate is provided with screws for connecting to the spindle box of an external radial drilling machine. Shaft holes are provided on both the connecting plate and the fixed plate, and a rotating shaft passes through the shaft holes. The rotating shaft connects to the external... The radial drilling machine is connected to the main drive shaft. A drive gear is installed at the lower end of the shaft, and a first connecting shaft is installed at the lower end of the drive gear. A plurality of fixing holes are provided around the fixing plate. A plurality of adjusting blocks are detachably installed on the lower end face of the fixing plate. Two parallel through slots are provided on each adjusting block, namely a first through slot and a second through slot. A fixing rod is inserted into the fixing hole, and a fixing block is provided at the end of the fixing rod. The fixing rod passes through the first through slot and the fixing hole in sequence. The fixing block abuts against the lower end face of the adjusting block. A first nut is threaded onto the fixing rod, and the lower end face of the first nut abuts against the upper end face of the fixing plate. An annular sliding groove is provided on the lower end face of the fixing plate, and the cross-sectional shape of the sliding groove is inverted. The T-shaped structure includes a fixed column slidably connected within the groove. The lower end of the fixed column passes through a first through groove. A second nut is threaded onto the fixed column, abutting against the lower end face of an adjusting block. A protrusion is provided at the end of the adjusting block, and a countersunk hole is formed on the protrusion. A first connecting rod is inserted into the countersunk hole. A first locking block is provided at the upper end of the first connecting rod, engaging within the countersunk hole. The upper end face of the first locking block is flush with the upper end face of the adjusting block. A third nut is threaded onto the first connecting rod, abutting against the lower end face of the protrusion. A first gear with a bearing is detachably mounted at the lower end of the first connecting rod. The first gear meshes with a driving gear. A second bearing is mounted on the lower end face of the first gear. The two connecting shafts have a groove on the upper end face of the adjusting block at the edge of the second through groove. A second connecting rod is slidably connected in the second through groove. A second locking block is provided at the end of the second connecting rod and engages in the groove. The upper end face of the second locking block is flush with the upper end face of the adjusting block. A fourth nut is threaded onto the second connecting rod and abuts against the lower end face of the adjusting block. A second gear with a bearing is installed at the lower end of the second connecting rod and meshes with a first gear. A third connecting shaft is installed on the lower end face of the second gear. Drill bits are detachably installed at the lower ends of the first, second, and third connecting shafts. Both the first and second gears are available in various diameter sizes.

[0006] Furthermore, taps are detachably installed at the lower ends of the first connecting shaft, the second connecting shaft, and the third connecting shaft.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] In this invention, the first gear meshes with the driving gear, and the second gear meshes with the first gear. When the rotating shaft is connected to the main drive shaft of an external radial drilling machine, the driving gear drives the first gear to drill, and the first gear drives the second gear to rotate, causing the first connecting shaft, the second connecting shaft, and the third connecting shaft to rotate. The drill bit or tap connected to the lower end of the first connecting shaft, the second connecting shaft, and the third connecting shaft can perform drilling or wire reeling.

[0009] In this invention, the first gear is connected to the protrusion of the adjusting block via a first connecting rod. The position of the adjusting block is adjusted according to the diameter of the first gear to allow the first gear to mesh with the driving gear. The adjusting block is slidably connected to the slide groove via a fixing rod and a fixing post, and then fixed by a first nut and a second nut, thus fixing the position of the adjusting block. Changes in the diameter of the first gear alter the distance between the second and first connecting shafts, resulting in different drilling positions. Furthermore, sliding the adjusting block changes the relative position of the second and first connecting shafts, also altering the drilling position. Sliding the adjusting block also allows the line connecting the second and first gears to form an angle with the line connecting the first and driving gears. When the angle is 180 degrees, the distance between the second and driving gears is greatest, resulting in the furthest drilling position formed by the first and third connecting shafts. Changes in the diameter of the second gear also adjust the relative position of the drilling holes. The drilling position can be achieved by adjusting the diameter of the gears or the position of the sliding adjusting block, allowing for adjustment of the position between holes while simultaneously drilling. Furthermore, the first, second, and third connecting shafts all rotate vertically, and the force is perpendicular during drilling, which can reduce the jamming phenomenon caused by the use of universal joints in existing technologies.

[0019] A specific embodiment, as shown in the figure, represents a preferred embodiment of the present invention. A multi-functional multi-spindle drilling and wire reeling device mainly includes a fixed frame and a connecting plate 16. The fixed frame mainly includes a fixed plate 3 and supports. Multiple supports are arranged around the outer side of the fixed plate 3, and the lower ends of the supports are all mounted on the annular frame 1. The connecting plate 16 is fixed above the fixed plate 3 by multiple studs 17. The connecting plate 16 has multiple connecting holes, and the studs 17 are inserted into the connecting holes. Upper nuts and lower nuts are threaded onto the studs 17, respectively abutting against the upper and lower end faces of the connecting plate 16, thus fixing the connecting plate 16 above the fixed plate 3. The upper end face of the connecting plate 16 is provided with screws 18 for connecting to the spindle box of an external radial drilling machine. The connecting plate 16 has shaft holes 20 on the fixed plate 3. A rotating shaft 19 is inserted inside the 20, and the rotating shaft 19 is connected to the main drive shaft of the external radial drilling machine. A drive gear 13 is installed at the lower end of the rotating shaft 19, and a first connecting shaft is installed at the lower end of the drive gear 13. A plurality of fixing holes 2 are provided around the fixing plate 3. A plurality of adjusting blocks 4 are detachably installed on the lower end face of the fixing plate 3. Two parallel through slots are opened on the adjusting block 4. The two through slots are a first through slot 5 and a second through slot 6, respectively. A fixing rod 10 is inserted into the fixing hole 2. A fixing block is provided at the end of the fixing rod 10. The fixing rod 10 passes through the first through slot 5 and the fixing hole 2 in sequence. The fixing block abuts against the lower end face of the adjusting block 4. A first nut is threaded on the fixing rod 10. The lower end face of the first nut abuts against the upper end face of the fixing plate 3.The lower end face of the fixing plate 3 has an annular groove 12. The groove 12 has an inverted T-shaped cross-section. A fixing post 11 is slidably connected within the groove 12. The lower end of the fixing post 11 passes through the first through groove 5. A second nut is threaded onto the fixing post 11, and the second nut abuts against the lower end face of the adjusting block 4. The end of the adjusting block 4 has a protrusion with a countersunk hole 21. A first connecting rod is inserted into the countersunk hole 21. A first locking block is provided at the upper end of the first connecting rod, and the first locking block engages within the countersunk hole 21. The upper end face of the first locking block is flush with the upper end face of the adjusting block 4. A third nut is threaded onto the first connecting rod, and the third nut abuts against the lower end face of the protrusion. A bearing is detachably mounted on the lower end of the first connecting rod. A first gear 14 meshes with a driving gear 13. A second connecting shaft is mounted on the lower end face of the first gear 14. A groove 22 is provided on the edge of the second through groove 6 on the upper end face of the adjusting block 4. A second connecting rod 8 is slidably connected in the second through groove 6. A second locking block 8-1 is provided at the end of the second connecting rod 8, and the second locking block 8-1 is engaged in the groove 22. The upper end face of the second locking block 8-1 is flush with the upper end face of the adjusting block 4. A fourth nut 7 is threaded onto the second connecting rod 8 and abuts against the lower end face of the adjusting block 4. A second gear 15 with a bearing is mounted on the lower end of the second connecting rod 8, and the second gear 15 meshes with the first gear 14. A third connecting shaft 9 is mounted on the lower end face of the second gear 15.

[0020] In practical application, this invention incorporates a fixing frame for protection, reducing the likelihood of contact with internal parts. During use, the distance between the fixing plate 3 and the connecting plate 16 is adjusted by adjusting the positions of the upper and lower nuts. The connecting plate 16 is then connected to the external machine tool spindle box via screws 18, thus connecting the fixing frame to the spindle box of the radial drilling machine. The radial drilling machine is existing technology and will not be described in detail here. The main drive shaft of the radial drilling machine is connected to the rotating shaft 19, allowing the rotating shaft 19 to rotate, causing the drive gear 13 at its lower end to rotate. The drive gear 13 meshes with the first gear 14, and the second gear 15 meshes with the first gear 14. Driven by the drive gear 13, the first gear 14 and the second gear 15 rotate, allowing drill bits or taps to be detachably mounted on the lower ends of the first connecting shaft, second connecting shaft, and third connecting shaft 9 for drilling or wire reeling. When the drilling location changes, the first nut on the fixing rod 10 and the second nut on the fixing post 11 can be unscrewed to adjust the position of the adjusting block 4. Alternatively, a suitable fixing hole 2 can be selected to fix the fixing rod 10, further adjusting the position of the adjusting block 4. This allows the first gear 14, mounted on the protrusion at the end of the adjusting block 4, to change its relative position to the driving gear 13 while maintaining meshing with it. Since the second gear 15 is always meshed with the first gear 14, the line connecting the second gear 15 and the first gear 14 forms an angle with the line connecting the first gear 14 and the driving gear 13, thus changing the relative position of the second gear 15 and the driving gear 13, thereby changing the drilling location. A drill bit can be installed at the lower end of the first gear 14 as needed. Furthermore, both the first gear 14 and the second gear 15 are available in various diameter sizes. When adjusting the position of the drill bit or tap alone is insufficient to accommodate the changes in the drilling position, different diameter first gear 14 or second gear 15 can be used. These different diameters alter the relative positions of the second and third connecting shafts 9 and the first connecting shaft. Adjusting the position using adjusting block 4 then allows for further adjustment of the drilling position. Once the position of the drill bit or tap is adjusted, the downward movement of the spindle box of the radial drilling machine will cause the fixing plate 3 of the fixed frame to move downwards, enabling the drill bit and tap to drill or ream wire.

[0021] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
