Description
Technical field
The utility model relates to a kind of hole making drill, specifically is bus heat-shrinkable T bush special adjustable formula hole making drill.
Background technology
Bus in the distribution electric supply installation is mains supply line, and each branch line is down drawn by main bus-bar.Bus is exposed can to exist safety problem, therefore generally is with heat-shrinkable T bush protection, stops the short trouble that toys such as mouse, snake cause, prevents chemical substances such as acid, alkali, salt to the corrosion of bus, prevents that laying dust from causing the discharge arcing.
Bus is generally by being bolted in the controller switching equipment, so offers several connecting holes usually on the bus, because bus is wrapped up by heat-shrinkable T bush, correspondingly, heat-shrinkable T bush also needs punching with construction bolt.Existing heat-shrinkable T bush perforate mode has following two kinds: one is to use sample towards the formula hole making drill, and the 2nd, directly manually cut with blade.Defective is: existing sample can not accomplish to regulate at any time the perforate size towards the formula hole making drill, sample dashes can only be towards a kind of hole of specification, and can not regulate its perforate degree of depth, the little purpose that can not reach perforate of exerting oneself, exerted oneself big and can injure bus, operate cumbersomely, it is short service life that sample dashes wearing and tearing easily; Artificial blade perforate can only opening square hole, do not open circular hole and the hole of opening irregular, can not accomplish that each hole is the same, profile is not attractive in appearance, is subjected to operator's level affects very big.
The utility model content
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of bus heat-shrinkable T bush special adjustable formula hole making drill is provided, and this hole making drill should have the perforate convenience, be easy to adjusting, high efficiency, characteristic of simple structure.
The technical solution adopted in the utility model is:
Bus heat-shrinkable T bush special adjustable formula hole making drill is characterized in that: the blade that described hole making drill comprises the rotating shaft of vertical layout, vertically the insert clamp of described axis one end is installed and vertically is fixed on the insert clamp bottom at the axis at rotating shaft middle part, by the anchor clamps fastening bolt by between centers fastening bolt horizontal lock; The top of described rotating shaft is connected with driving mechanism, and the aperture coupling of the diameter of axle of lower end and the connecting hole of bus keeps a determining deviation between described blade and the rotating shaft.
The middle part of described rotating shaft offers the horizontal through hole with the axis coupling, and the middle part of axis is installed in this horizontal through hole, and described between centers fastening bolt inserts and push against described axis from the rotating shaft outer wall towards horizontal through hole.
Offer the horizontal through hole that mates with axis on the described insert clamp, described anchor clamps fastening bolt inserts and pushes against described axis from the outer wall of insert clamp towards horizontal through hole.
The bottom of described insert clamp is provided with the blade fixture block for clamping blade, and this blade fixture block is fixed on the insert clamp by the cutter trip bolt.
Described driving mechanism is electric drill or bench drill.
Operation principle of the present utility model is:
Unclamp the anchor clamps fastening bolt, adjust the position of insert clamp on axis, make distance between blade and the shaft axis equal the circle hole radius that to open, locking fixture fastening bolt again; In case of necessity, can unclamp the between centers fastening bolt, regulate the position of axis, make axis keep balance, fastening bolt between lock shaft again;
Afterwards rotating shaft is aimed at straight down the connecting hole of bus, restart driving mechanism, by the rotation of rotating shaft, drive blade and move in a circle, the blade cuts heat-shrinkable T bush is finished out the work of circular hole like this.
The beneficial effects of the utility model are: the size that this adjustable hole making drill can circular hole that step-less adjustment is opened, and an adjustable hole making drill can have a lot of perforate specifications to regulate; And the up-down adjustment by blade, can ideally heat-shrinkable T bush be cut off and do not injure bus, it is uniform that all collar aperture of opening can be accomplished, and the efficient height.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, bus heat-shrinkable T bush special adjustable formula hole making drill described in the utility model comprises that rotating shaft 1, the level of vertical installation is installed in the axis 2 in the rotating shaft, the blade 7 that vertically is installed in the insert clamp 5 of axis one end and is installed in the 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, the rotating shaft upper end is fixed in the chuck 9 of electric drill, the aperture coupling (bottom is tapered) of the connecting hole 10-1 of the diameter of axle of rotating shaft lower end and bus 10, make the rotating shaft lower end can insert in the connecting hole, roughly with the connecting hole coaxial arrangement.The middle part of rotating shaft is flat square shape and offers the horizontal through hole (center line of horizontal through hole and the axes intersect of rotating shaft) that mates with axis, and the middle part of axis is installed in this horizontal through hole, and the axis of this horizontal through hole and the axis normal of rotating shaft are arranged.In order to prevent skidding, described axis recommends to adopt rectangular shape (horizontal through hole is the square hole that adapts to it), offer horizontally disposed screwed hole at the rotating shaft middle part, there is a between centers fastening bolt 3 to be installed in the screwed hole, this between centers fastening bolt inserts and pushes against described axis from the rotating shaft outer wall towards horizontal through hole, thereby with its locking (rotating shaft, axis, between centers fastening bolt are arranged vertically in twos).After unclamping the between centers fastening bolt, axis can slide in horizontal through hole.
Described insert clamp is the square shape, also offer the horizontal through hole (the vertical center line of the center line of horizontal through hole and insert clamp intersects) with the axis coupling on this insert clamp, the top of insert clamp offers the screwed hole of vertical layout, have an anchor clamps fastening bolt 4 to insert and push against described axis from the upper end of insert clamp towards horizontal through hole, this anchor clamps fastening bolt and shaft parallel are arranged.
