Description
Technical field
This utility model relates to a kind of drilling equipment, particularly relates to a kind of drill bit variable-angle rig.
Background technology
In a lot of bases or connector, in order to realize special connection, it is necessary to bore some and tilt the hole with plane, but owing to the drill bit of present rig is all vertically or horizontally, and drill bit is all fixing; So for the hole getting out workpiece surface thereof and plane, it is necessary to when clamping workpiece, make workpiece favour drill bit; Therefore for the hole of differing tilt angles on workpiece, it is necessary to design different frocks, so that relatively costly, and change to the hole of differing tilt angles, it is necessary to reinstall frock and positioning fixture, hence in so that working (machining) efficiency is relatively low.
Utility model content
This utility model is intended to provide a kind of drill bit variable-angle rig, to be completed the boring of angling hole by rotary drill bit.
Base case drill bit variable-angle rig of the present utility model, including frame, rotating seat, drive division and bore portion, described rotating seat is rotatably connected in frame, and rotating seat is driven by drive division; It is also provided with universal joint; Described bore portion includes power transmission shaft, sleeve pipe, feeding block and drill bit; Described sleeve pipe is rotatably connected in described frame, is provided with female thread in sleeve pipe, and described feeding block is provided with external screw thread, and feeding block is arranged in described sleeve pipe, and feeding block coordinates with casing threads; One end of described feeding block is provided with internal spline, described drill bit is fixedly connected on the other end of feeding block, one end of described power transmission shaft is that the spline being slidably matched is connected with feeding block, the other end of power transmission shaft is fixing with one end of described universal joint to be connected, and the other end of universal joint and described rotating seat are fixed; And it is additionally provided with trip bolt between described sleeve pipe and described frame.
In this base case, drive division is PTO, and in order to drive rotating seat to rotate, and drive division has reversing device, in order to realize the rotating of rotating seat. When needing with the angle of a certain inclination, workpiece is turned hole, rotating casing then can make drill bit point to workpiece at an angle, then trip bolt is fastened, making sleeve pipe and frame is stationary state, and make rotating seat rotate, under the effect of universal joint, rotating seat will drive feeding block to rotate, so that drill bit rotates; Feeding block rotate simultaneously as feeding block and sleeve pipe are threaded engagement, and be now stationary state due to sleeve pipe, so also will move forward in sleeve pipe when feeding block rotates, so that drill bit can realize feeding when holing; When rotating seat reverses, then drill bit can be made to exit from workpiece.
In this base case, universal joint is in order to realize the transmission of varied angle power, the sleeve pipe of bore portion and feeding block, it may be achieved when feeding block drives drill bit to rotate, and drives drill bit to realize feeding simultaneously;Owing to power transmission shaft can only rotate, it is impossible to realize axial movement, so power transmission shaft is that the spline being slidably matched is connected with feeding block, feeding block can be made to realize feeding while, power transmission shaft with feeding block without departing from being connected.
This utility model carrys out the angle of drill bit by the angle adjustable of the sleeve pipe of bore portion, the transmission of varied angle power is realized by universal joint, and the cooperation passing through sleeve pipe, feeding block and power transmission shaft can realize rotation and the feeding of drill bit, so that the boring of angling hole can be completed by rotary drill bit.
Preferred version one, as the further optimization to base case, described universal joint is ball cage type universal joint; Ball cage type universal joints structure is more stable, stuck phenomenon not easily occurs.
Preferred version two, as the further optimization to base case, the two ends of described universal joint are provided with adpting flange, and described power transmission shaft and rotating seat are also equipped with adpting flange, and described universal joint and described power transmission shaft are Flange joint with rotating seat; Universal joint is Flange joint with power transmission shaft and rotating seat, is conducive to changing universal joint, and the structure of Flange joint is relatively stable so that loosening phenomenon not easily occurs in universal joint.
Preferred version three, as the further optimization to base case, described frame is provided with graduated disc; Graduated disc is set and can determine, by the value of reading graduated disc, the angle that drill bit rotates.
Preferred version four, as the further optimization to base case, described feeding block is provided with taper hole, and described drill bit and described feeding block are taper fit; Drill bit and feeding block are the fastening that taper fit is conducive to drill bit and feeding block, and more bit change is also more convenient simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic front view of drill bit variable-angle rig embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: frame 1, rotating seat 2, universal joint 3, bore portion 4, graduated disc 5, cantilever 11, power transmission shaft 41, sleeve pipe 42, drill bit 43, feeding block 44.
Embodiment is substantially as shown in Figure 1: drill bit variable-angle rig includes frame 1, rotating seat 2, universal joint 3 and bore portion 4; Wherein having cantilever 11 in frame 1, rotating seat 2 is rotatably connected on the cantilever 11 of frame 1, and rotating seat 2 is driven by drive motor. Bore portion 4 includes power transmission shaft 41, sleeve pipe 42, feeding block 44 and drill bit 43; Its middle sleeve 42 is rotatably connected in frame 1, is provided with female thread, and feeding block 44 is provided with external screw thread in sleeve pipe 42, and feeding block 44 is arranged in sleeve pipe 42, and feeding block 44 and sleeve pipe 42 threaded engagement; One end of feeding block 44 is provided with internal spline, and the other end is provided with taper hole, and drill bit 43 and feeding block 44 are taper fit, and one end of power transmission shaft 41 is that the spline being slidably matched is connected with feeding block 44, and the other end of power transmission shaft 41 is provided with ring flange; Universal joint 3 is ball cage type universal joint 3, and the two ends of universal joint 3 have two adpting flanges, and one of them adpting flange is bolted on rotating seat 2, and another adpting flange is bolted on the ring flange of power transmission shaft 41.
It is additionally provided with trip bolt, to show that sleeve pipe 42 can be fastened in frame 1 between sleeve pipe 42 and frame 1. When needing with the angle of a certain inclination, workpiece is turned hole, rotating casing 42 then can make drill bit 43 point to workpiece at an angle, fastening trip bolt, make sleeve pipe 42 and frame 1 in stationary state, then start drive motor, make rotating seat 2 rotate, under the effect of universal joint 3, drive feeding block 44 is rotated by rotating seat 2, so that drill bit 43 rotates;Feeding block 44 rotate simultaneously as feeding block 44 and sleeve pipe 42 be threaded engagement, and due to sleeve pipe 42 now for stationary state so when feeding block 44 rotates, also moving forward in sleeve pipe 42 so that drill bit 43 can realize feeding when holing; Reverse starting drive motor after boring completes, then can make drill bit 43 exit from workpiece.
The angle that drill bit 43 rotates as it is shown in figure 1, change the angle of drill bit 43 for the ease of rotating casing 42, frame 1 is provided with graduated disc 5, thus can be read from graduated disc 5.
