Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
As it is shown in figure 1, a kind of horizontal chasing bar of bench drill, including: base 1, fixed support 2, rotating shaft 3, passively rub
Wipe wheel 4, active friction wheel 5, fricting strip 6, connecting shaft 7, fixture 8；Described fixed support 2 is fixed on described base 1, described turn
Axle 3 is movably connected on described fixed support 2 and in being horizontally disposed with, and which is provided with driven pulley 4, and end is provided with fixture 8；Institute
Stating driven pulley 4 and have two, in cone, two driven pulley 4 coneheads are oppositely arranged, and described driven pulley 4
The axis of axis and described rotating shaft 3 is on same straight line；Described active friction wheel 5 in inverted cone, be positioned at two passive
Between friction pulley 4, leave space between the conical surface of its conical surface and two driven pulley 4, on the conical surface of described active friction wheel 5
Being provided with some annular grooves 51, described fricting strip 6 is placed in described annular groove 51；Described connecting shaft 7 is vertically fixed on actively
Friction pulley 5 top center；Described guide rail 9 is arranged on described base 1, and described workpiece clamp platform 10 is slidably arranged in described guide rail 9
Go up and just to fixture 8, be provided with driving motor 11 in described workpiece clamp platform 10 and drive described workpiece clamp platform 10.Described active friction wheel
5 buses are equal with bottom surface angle angle with driven pulley 4 bus with the angle of bottom surface.Described fixed support 2 has two, described
Driven pulley 4 is between two fixed supports 2.Described annular groove 51 has two.
The spindle operation of drilling machine, spindle nose connects active friction wheel 5 by connecting shaft 7, is allowed to turn round together.When to work
During part tapping, driving motor 11 to drive workpiece clamp platform 10 to vertically move along drilling machine, workpiece contacts with the screw tap of rotating shaft 3 end
