Description

A kind of horizontal chasing bar of bench drill
Technical field
This utility model relates to a kind of horizontal chasing bar of bench drill.
Background technology
Tapping is in parts housing, in the various sizes of through hole such as equipment end face, nut and ring flange or blind hole Revolving body processing screw thread.The Main Function of screw thread is connection, installs cover plate and fixed position etc., is that machinery manufacturing industry is indispensable A kind of processing method.
Drilling machine is a kind of boring instrument, is all vertical direction, if needing horizontal tapping, then needs other tapping Device or carry out hand tapping, the efficiency of hand tapping is low, and quality stability is poor, if additionally buying threading apparatus, then increases Add cost.
Utility model content
This utility model purpose is: in order to solve the problem that the prior art in above-mentioned background technology exists, it is provided that one Plant the horizontal chasing bar of bench drill.
This utility model solves its technical problem and be the technical scheme is that a kind of horizontal chasing bar of bench drill, Including: base, fixed support, rotating shaft, driven pulley, active friction wheel, fricting strip, connecting shaft, fixture;Described fixed support Being fixed on described base, described rotating shaft is movably connected on described fixed support and in being horizontally disposed with, and which is provided with and passively rubs Wiping wheel, end is provided with fixture;Described driven pulley has two, and in cone, two driven pulley coneheads are oppositely arranged, and The axis of the axis of described driven pulley and described rotating shaft is on same straight line;Described active friction wheel is back taper Shape, between two driven pulley, leaves space between the conical surface of its conical surface and two driven pulley, described active rubs The conical surface wiping wheel is provided with some annular grooves, and described fricting strip is placed in described annular groove;Described connecting shaft is vertically fixed In active friction wheel top center, described guide rail is arranged on described base, and described workpiece clamp platform is slidably arranged in described guide rail Go up and just to fixture, be provided with driving motor in described workpiece clamp platform and drive described workpiece clamp platform.
As further preferred version: the angle of described active friction wheel bus and bottom surface and driven pulley bus with Bottom surface angle angle is equal.
As further preferred version: described fixed support has two, described driven pulley is positioned at two fixing Between frame.
As further preferred version: described annular groove has two.
The beneficial effects of the utility model are: realize the horizontal tapping of bench drill, and simple in construction is easy to operate.
Motor drives workpiece clamp platform, and the speed of service is stable, and Tapping Quality is high.
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 Time, produced external force promotes rotating shaft 3 to move axially to the left, makes the wheel of the driven pulley 4 on active friction wheel 5 and right side Face contacts, and produces stiction, drives rotating shaft 3 to turn round clockwise, it is achieved tapping.When tapping to working depth, workpiece edge Axis direction is return, and workpiece rotating shaft 3 moves right vertically, makes the wheel face of the driven pulley 4 in active friction wheel 5 and left side Contact, makes rotating shaft 3 reversion exit screw tap, completes tapping.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people Member can carry out various change and amendment completely in the range of without departing from this utility model technological thought.This reality The content being not limited in description by novel technical scope, it is necessary to determine its technology according to right Property scope.
