Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a drilling and tapping integrated machining device. Background Art

[0002] In the traditional machining process, drilling and tapping are two independent processes that need to be completed using a drilling machine and a tapping machine respectively. This method is not only inefficient, but also difficult to ensure machining accuracy due to the two clamping and positioning. In order to solve this problem, a drilling and tapping machine has been invented in the prior art, which can complete the two processes of drilling and tapping in one clamping and positioning. However, in the actual use of the current drilling and tapping machine, although the workpiece does not need to be clamped twice, it requires workers to manually replace the corresponding drill bit and tapping head before drilling or tapping. This replacement process not only takes up the processing time of the drilling and tapping machine, but also once the drill bit and tapping head are not fixedly installed, it will also cause the wear of the drill bit and tapping head to increase and reduce the life.

Since the nut 43 that is threadedly connected to the screw rod 42 is fixedly installed on the lifting bracket 3, and the lifting bracket 3 is slidably connected to the square pillar 2, the nut 43 will drive the lifting bracket 3 to slide up and down relative to the square pillar 2 under the rotation of the screw rod 42, thereby achieving the effect of adjusting the height of the lifting bracket 3.

One end of the rotating cylinder 82 is fixedly connected to the center of one side of the rotating exchange box 7, and the lifting rod 5 is located at the opening of the groove 81 and is screwed with a cover plate 87. Among them, the rotating exchange box 7 includes a box body 71 and a box cover 72.

[0025] like Figure 1 , Figure 2As shown, the rotating mechanism 11 includes a rotating shaft 111 that rotates through the rotating cylinder 82 and one end of which passes into the interior of the box 71, a driving bevel gear 112 that is fixedly mounted on the rotating shaft 111 and located inside the box 71, a pair of driven bevel gears 113 that are respectively rotatably arranged on the upper and lower sides of the interior of the box 71 and mesh with the driving bevel gear 112, and a worm gear reduction motor 114 that is fixedly mounted on one side of the lifting rod 5 and has its output end connected to the rotating shaft 3 84. The worm gear reduction motor 114 is located on the side of the lifting rod 5 away from the box 71, and one end of the rotating shaft 111 is fixedly plugged into the output end of the worm gear reduction motor 114. The upper and lower side walls of the box 71 are respectively rotatably passed through quick-release connectors 12, and the quick-release connectors 12 connect the driven bevel gears 113 and the drill bit 9 or the driven bevel gear 113 and the tapping head 10 on the inner and outer sides of the box 71. By adopting the above-mentioned rotating mechanism 11, not only can the drill bit 9 and the tapping head 10 on the upper and lower sides of the box body 71 be effectively driven to rotate, but the transmission structure of the active bevel gear 112 and the driven bevel gear 113 can also actively adapt to the rotation of the box body 71 to ensure the effective replacement of the upper and lower drill bits 9 and tapping heads 10 of the box body 71.

[0026] like Figure 2 , Figure 3 As shown, the quick-release connector 12 includes a fixed sleeve 121 fixedly connected to the driven bevel gear 113, a connecting head 122 movably inserted into the fixed sleeve 121 and rotated out of the side wall of the box body 71, a connecting hole 123 opened at the end of the connecting head 122 extending away from the box body 71 and for the end of the drill bit 9 or the tapping head 10 to be inserted, a pair of threaded holes 124 opened at the bottom of the fixed sleeve 121, a pair of fixing screws 125 respectively passing through the bottom of the connecting hole 123 and threadedly connected to the threaded hole 124, a pair of threaded holes 126 respectively opened on the side walls of the drill bit 9 or the tapping head 10, and a pair of fixing screws 127 respectively passing through the side walls of the connecting head 122 and entering the connecting hole 123 to respectively connect the two threaded holes 126.

[0027] The working principle of this embodiment:

[0028] When the workpiece is drilled and needs to be tapped, first the stepper motor 86 will drive the rotating shaft three 84 to rotate, so that the worm 85 on the rotating shaft three 84 engages the transmission worm wheel 83 to rotate, and then the worm wheel 83 will drive the rotating cylinder 82 connected thereto to rotate, so that the rotating cylinder 82 drives the rotary exchange box 7 to rotate, and then in this way the drill bit 9 and the tapping head 10 on the upper and lower sides of the rotary exchange box 7 are exchanged, and then when the rotating cylinder 82 rotates 180 degrees and the tapping head 10 is exchanged to the bottom of the rotary exchange box 7, the stepper motor 86 will immediately stop driving the rotating shaft three 84 to keep the tapping head 10 in a vertical downward state at this time. Since the drill bit 9 and the tapping head 10 are symmetrically located on the rotary exchange box 7, and the rotary exchange box 7 rotates around its center, the tapping head 10 exchanged to the bottom will be exactly aligned with the position where the workpiece has just been punched, and then the worm gear reduction motor 114 is started to drive the rotating shaft four 111 to rotate, so that the rotating shaft four 111 drives The driving bevel gear 112 inside the rotary exchange box 7 rotates and meshes to drive the upper and lower driven bevel gears 113 to rotate. Because the two driven bevel gears 113 are respectively connected to the tapping head 10 and the drill bit 9 through the quick-release connector 12, the drill bit 9 and the tapping head 10 on the upper and lower sides of the rotary exchange box 7 will rotate synchronously when the two driven bevel gears 113 rotate. Finally, the operator manually pulls the hand pull rod 65 on one side of the lifting bracket 3 to rotate the rotating shaft 2 63 to drive the driving gear 64 thereon to rotate and mesh with the transmission rack 62. Since the rack 62 is fixed in the long hole 61 of the lifting rod 5, and the lifting rod 5 slides through the lifting bracket 3, the entire lifting rod 5 and the rotary exchange box 7 will slide relative to the lifting frame together when the driving gear 64 meshes with the transmission rack 62. At the same time, the tapping head 10 rotating at the bottom of the rotary exchange box 7 will gradually extend into the workpiece hole during the sliding process of the above-mentioned lifting rod 5, thereby performing tapping processing on the workpiece hole. During the above-mentioned automatic replacement process of the drill bit 9 and the tapping head 10, not only the replacement speed is fast and the replacement efficiency is high, but the entire process is also mechanically controlled by the stepping motor 86, the worm gear 83 and the worm 85, so the replaced drill bit 9 or tapping head 10 has strong stability and high precision.
