Technical field
The utility model relates to a kind of supporting annex of using on radial drilling machine, relate in particular to the drilling tool of closed or semi-enclosed box body hole processing usefulness.
Background technology
For closed or semienclosed casing, housing series products, the moment of torsion Transfer Gearbox of U.S. Ka Si Imtech for example is because structural reason, the hole site is more special, process as radial drilling machine, certainly will cause drilling machine and part to be processed to collide, cause security incident by routine.
Summary of the invention
Goal of the invention of the present utility model is to avoid the defective of prior art and provides a kind of closed or semi-enclosed box body hole that can do the processing of ad-hoc location hole to process drilling tool.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of closed or semi-enclosed box body hole processing drilling tool, it comprises and connects the radial drilling machine gear drive and drive the main shaft of rotation and elevating movement by it, the main shaft endoporus is a taper hole, it is characterized in that also being provided with on the described radial drilling machine main shaft chuck with the main shaft synchronization lifting, described main shaft chuck below is provided with the support plate that is connected by support bar; Being fitted in end bearing under the rotating shaft in the spindle taper hole is connected in the pair of bearings in the support plate, described support plate cantilever end is provided with the drilling tool axle of band drill chuck, the supporting of this drilling tool axle be connected the support plate cantilever end another in the bearing, and between rotating shaft and drilling tool axle, be provided with the driving member of transferring power.
Described driving member is belt wheel pair or chain wheel pair.
Described support bar is provided with 2～4.
Be arranged with spring on the described support bar.
The driving member of described transferring power is connected with rotating shaft, drilling tool axle key respectively.
Compared with prior art, the utility model provides a kind of specific drilling tool for closed or semi-enclosed box body hole processing, this drilling tool is as the annex of acorde bur bed apparatus, utilize the transmission of power of the power of drilling machine by driving member, solved the special and difficult problem that is difficult to finish processing in hole site in the closed or semi-enclosed casing by plain radial drilling machine, for closed or semi-enclosed box body hole processing technology provides the frock assurance, and safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
As shown in Figure 1, among the figure: 1, main shaft chuck, 2, spring, 3, support bar, 4, main shaft, 5, rotating shaft, 6, pair of bearings, 7, support plate, 8, the belt wheel pair, 9, pad, 10, screw, 11, another is to bearing, 12, drill chuck, 13, the drilling tool axle.
Closed or semi-enclosed box body hole processing drilling tool, comprise and connect the radial drilling machine gear drive and drive the main shaft 4 of rotation and elevating movement by it, this main shaft endoporus is a taper hole, can be equipped mutually with the tapering of unit-type drill head, and this moment, radial drilling machine can be done plain bore processing.When using as closed or semi-enclosed box body hole processing drilling tool, what be equipped with in the spindle taper hole is rotating shaft 5, while is connected with the main shaft chuck 1 with main shaft 4 synchronization liftings on the radial drilling machine after the repacking, be provided with the support plate 7 that is connected by support bar 3 below the main shaft chuck; A rotating shaft 5 identical with the drill bit standard taper is fitted in the spindle taper hole, by main shaft driven rotary and elevating movement, the following end bearing of rotating shaft is connected in the pair of bearings 6 in the support plate 7, support plate stretches out into cantilever end according to the needs of hole Working position, be Long Circle, be provided with band drill chuck 12 so that the drilling tool axle 13 of clamping drilling bit at cantilever end, 11 supportings connect this drilling tool axle to bearing with in the support plate 7 another equally, the driving member of transmission of power is set between rotating shaft and drilling tool axle simultaneously, this driving member can be belt wheel pair or chain wheel pair, present embodiment adopts belt wheel pair 8, belt wheel in the rotating shaft all is connected with key with belt wheel on the drilling tool axle, can be singly-bound or spline, form drive connection.The drilling tool axle is fixed on the drilling tool axle 13 with pad 9, screw 10 after connecting upper belt-wheel, prevents that belt wheel transferring power process from flying out.The rotary power of main shaft 4 passes to drilling tool axle 13 by this belt wheel pair 8, realizes drill tasks thereby drive the drill bit that is clamped by drill chuck 12.
Support bar 3 is provided with 2～4, is that circumference uniform distribution connects or other symmetry connects, and present embodiment is selected 2 for use, is arranged with spring 2 simultaneously on support bar, with the caused vibration of holing of buffering cantilever beam.
