Description
Technical field
The utility model relates to a kind of hole making drill, particularly relates to a kind of hard copper bus heat-shrinkable T bush hole making drill.
Background technology
Hard copper bus (abbreviation copper busbar) general when dispatching from the factory in order to protect copper busbar, in copper busbar, coated one deck material is polyolefinic insulating barrier.At present, in the process of copper busbar heat-shrinkable T bush perforate, owing to there is no corresponding tapping equipment, cause in Tapping procedures, use easy cutter to carry out perforate, this method cause otch rough, very easily destroy copper busbar heat-shrinkable T bush and unsightly; Or use belt punch to carry out perforate, though this method aesthetically makes moderate progress, but very easily cause the damage of belt punch, and compare effort, increase labour cost, and be uneconomic for whole process.
Summary of the invention
The purpose of this utility model is to provide a kind of copper busbar heat-shrinkable T bush hole making drill, and this hole making drill is easy to use, and cost is low, improves the working (machining) efficiency of copper busbar heat-shrinkable T bush perforate.
In order to above-mentioned technical purpose, the utility model adopts following technical scheme:
A kind of copper busbar heat-shrinkable T bush hole making drill, comprise turning cylinder, alignment pin, circle roll blade, stop nut, fixed cover, handle and bolt, described turning cylinder is convex shoulder type, upper diameter is little, lower diameter is large, and lower bottom part radially has through hole, and through hole is through bottom shaft centre line, alignment pin is through turning cylinder through hole, and at alignment pin two ends, turning cylinder both sides are provided with round roll blade and stop nut successively; Described fixed cover inner face is convex shoulder type through hole, above internal diameter little, below internal diameter large, turning cylinder matches with fixed cover through fixed cover inner face, and turning cylinder can rotate in fixed cover, and turning cylinder top has screw, by bolt, handle is fixed on turning cylinder top.
Have a projection in turning cylinder bottom centre, projection top is spherical.
The structure that the utility model adopts turning cylinder, fixed cover and circle roll blade to combine, its structure is simple, easy to use, cost is low, shorten copper busbar heat-shrinkable T bush perforate process, process easy, and to have stopped in the process of copper busbar heat-shrinkable T bush perforate unsightly and uneconomic deficiency, raising working (machining) efficiency that simultaneously can be larger.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1 to Fig. 2, a kind of copper busbar heat-shrinkable T bush hole making drill, comprise turning cylinder 1, alignment pin 2, circle roll blade 3, stop nut 4, fixed cover 5, handle 6 and bolt 7, described turning cylinder 1 is convex shoulder type, and upper diameter is little, and lower diameter is large, lower bottom part radially has through hole, through hole is through bottom shaft centre line, and alignment pin 2 is through turning cylinder 1 through hole, and at alignment pin 2 two ends, turning cylinder 1 both sides are provided with round roll blade 3 and stop nut 4 successively; Described fixed cover 5 inner face is convex shoulder type through hole, above internal diameter little, below internal diameter large, turning cylinder 1 matches with fixed cover 5 through fixed cover 5 inner face, turning cylinder 1 can rotate in fixed cover 5, and turning cylinder 1 top has screw, by bolt 7, handle 6 is fixed on turning cylinder 1 top.Locate for ease of turning cylinder 1, there is a projection in described turning cylinder 1 bottom centre, and projection top is spherical.
The utility model copper busbar heat-shrinkable T bush hole making drill course of work:
See Fig. 3 and Fig. 4, during use, the utility model copper busbar heat-shrinkable T bush hole making drill 8 is vertically placed with on copper busbar heat-shrinkable T bush 9, and the ball bumps bottom turning cylinder 1 is aimed at the locating hole on copper busbar heat-shrinkable T bush 9, if there is no locating hole, then copper busbar heat-shrinkable T bush hole making drill 8 is accurately positioned over and needs tapping; A hand pins fixed cover 5, another hand is pressed and turning handle 6, circle roll blade 3 rolls along a circumference under turning cylinder 1 drives, circle roll blade 3 is evenly cut on copper busbar heat-shrinkable T bush 9, take away copper busbar heat-shrinkable T bush hole making drill 8 after rotating about 2 to 3 circles, circular hole machines, takes away after being set in copper busbar 10 thermal shrinkable sleeve pore, obtain containing the copper busbar 10 of perforate, see Fig. 4 be machine after design sketch.
Should avoid when the stop nut 4 of the utility model copper busbar heat-shrinkable T bush hole making drill screws causing round roll blade 3 stuck, stop nut 4 is torqued-up to round roll blade 3 and can rotates, can not too pine, uneven and cause accelerating the wearing and tearing of circle roll blade when preventing from cutting.The advantage of employing circle roll blade 3 is: except shear action, also have roll extrusion effect, can effectively improve machined surface quality, greatly cut down finished cost, also reduce the loss of blade, its durability is high, higher than general blade durability tens times, improve economy.
These are only preferred embodiment of the present utility model; be not intended to limit protection domain of the present utility model; therefore, all do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
