Description
Technical field
The present invention relates to a kind of hole making drill, the specifically special adjustable perforator of bus heat-shrinkable T bush.
Background technology
Bus in distribution electric supply installation is mains supply line, and each branch line is down drawn by main bus-bar.There is safety problem in the exposed meeting of bus, is the most typically cased with heat-shrinkable T bush and protects, and stops the chemical substance corrosion to bus such as the short trouble that the toy such as mouse, Serpentis causes, anti-antacid, alkali, salt, prevents laying dust from causing electric arc of discharge.
Bus is typically bolted in controller switching equipment, therefore generally offers several connecting holes on bus, and owing to bus is wrapped up by heat-shrinkable T bush, correspondingly, heat-shrinkable T bush is also required to punching to install bolt.Existing heat-shrinkable T bush perforate mode has following two: one is to use sample to rush formula hole making drill, and two is that direct blade manually cuts.Defect is: existing sample rushes formula hole making drill can not be accomplished to regulate perforate size at any time, one sample punching can only rush the hole of a kind of specification, and its perforate degree of depth can not be regulated, the firmly little purpose that can not reach perforate, exert oneself the biggest and can injure bus, operating cumbersome, sample punching easily abrasion is short for service life；Artificial blade perforate can only opening square hole, do not open circular hole and the hole opened be irregular, it is impossible to as accomplishing each hole, profile unsightly, is affected the biggest by the level of operator.
Summary of the invention
It is an object of the invention to overcome the deficiency in above-mentioned background technology, it is provided that a kind of special adjustable perforator of bus heat-shrinkable T bush, this hole making drill should have perforate facilitate, can easily be accommodated, work efficiency height, the feature of simple in construction.
The technical solution used in the present invention is:
The special adjustable perforator of bus heat-shrinkable T bush, it is characterised in that: described hole making drill includes the rotating shaft vertically arranged, by between centers fastening bolt horizontal lock axis in the middle part of rotating shaft, by the insert clamp of the vertically-mounted described axis one end of clamp bolt and be vertically fixed on the blade bottom insert clamp；The top of described rotating shaft is connected with drive mechanism, and the diameter of axle of lower end mates with the aperture of the connecting hole of bus, keeps a determining deviation between described blade and rotating shaft.
The middle part of described rotating shaft offers the horizontal through hole mated with axis, and the middle part of axis is arranged in this horizontal through hole, and described between centers fastening bolt is inserted towards horizontal through hole from rotating shaft outer wall and pushes against described axis.
Offering the horizontal through hole mated with axis in described insert clamp, described clamp bolt inserts towards horizontal through hole from the outer wall of insert clamp and pushes against described axis.
The bottom of described insert clamp is provided with the blade fixture block for clamping blade, and this blade fixture block is fixed in insert clamp by cutter trip bolt.
Described drive mechanism is electric drill or bench drill.
The operation principle of the present invention is:
Unclamp clamp bolt, adjust insert clamp position on axis so that the distance between blade and shaft axis is equal to circle hole radius to be opened, then locking fixture fastening bolt；If desired, between centers fastening bolt, the position of regulation axis can be unclamped, make axis keep balance, then lock between centers fastening bolt；
Rotating shaft being directed at the connecting hole of bus afterwards straight down, restarts drive mechanism, by the rotation of rotating shaft, band cutting blade moves in a circle, such blade cutting heat-shrinkable T bush, completes out the work of circular hole.
The invention has the beneficial effects as follows: this adjustable perforator can be with the size of the opened circular hole of step-less adjustment, and an adjustable perforator can have a lot of orifice configurations to regulate；And by the up-down adjustment of blade, ideally heat-shrinkable T bush can be cut off and not injure bus, all collar aperture opened can be accomplished uniform, and efficiency is high.

Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited in following example.
As it is shown in figure 1, the special adjustable perforator of bus heat-shrinkable T bush of the present invention, the axis 2 including vertically-mounted rotating shaft 1, being horizontally arranged in rotating shaft, the insert clamp 5 being vertically installed at axis one end and the blade 7 being arranged on insert clamp lower end.
The upper end of described rotating shaft is connected with actuating unit, actuating unit is generally electric drill or bench drill, rotating shaft upper end is fixed in the chuck 9 of electric drill, the diameter of axle of rotating shaft lower end mates (bottom is tapered) with the aperture of the connecting hole 10-1 of bus 10, rotating shaft lower end is made to may be inserted in connecting hole, substantially coaxially arranged with connecting hole.The middle part of rotating shaft is flat square block and offers the horizontal through hole (centrage of horizontal through hole and the axes intersect of rotating shaft) mated with axis, and the middle part of axis is arranged in this horizontal through hole, and the axis of this horizontal through hole is arranged vertically with the axis of rotating shaft.In order to prevent skidding, described axis is recommended to use rectangular shape (horizontal through hole is the square hole adapted to therewith), horizontally disposed screwed hole is offered in the middle part of rotating shaft, a between centers fastening bolt 3 is had to be arranged in screwed hole, this between centers fastening bolt inserts towards horizontal through hole and pushes against described axis from rotating shaft outer wall, thus is locked (rotating shaft, axis, between centers fastening bolt are arranged vertically two-by-two).After unclamping between centers fastening bolt, axis can slide in horizontal through hole.
Described insert clamp is square block, also the horizontal through hole (centrage of horizontal through hole intersects) with axis coupling is offered with the vertical centrage of insert clamp in this insert clamp, the top of insert clamp offers the screwed hole of vertically layout, having a clamp bolt 4 insert towards horizontal through hole from the upper end of insert clamp and push against described axis, this clamp bolt is arranged with shaft parallel.
The bottom of described insert clamp is provided with the blade fixture block 8 for clamping blade 7, and this blade fixture block is fixed in insert clamp by two cutter trip bolts 6, and blade is between blade fixture block and insert clamp, and between two trip bolt cutters.After unclamping blade fixture block, the position of blade can be adjusted up and down.The vertical centrage of blade fixture block, the vertical centrage of blade, the vertical centrage of insert clamp, the axis of rotating shaft are positioned at same perpendicular, thus ensure the balance of hole making drill.
When the rotating shaft of hole making drill is arranged on electric drill or bench drill, by the rotation of rotating shaft, band cutting blade moves in a circle, and such blade cutting material completes out the work of circular hole.There is square hole in the middle of insert clamp and rotating shaft, be fixed together with axis by each fastening bolt.The size of opened circular hole is adjusted by the spacing adjusting insert clamp and rotating shaft；The degree of depth of perforate is regulated by regulation blade and half-breadth；Adjust the center of gravity of whole hole making drill with the relative position of fixture and rotating shaft by adjusting axis, in the hope of by gravity's center control on the centrage of rotating shaft, on-stream being maintained of the most whole hole making drill balances.
The feature of the present invention has: 1. blade is stepless adjustable with the spacing of rotating shaft；2. blade and half-breadth is stepless adjustable；3. can reach to balance the effect of whole device by regulation axis with the relative position of rotating shaft and cutting blade clip.
Figure also has, heat-shrinkable T bush 11, circular hole 11-1.
