Description

Drilling machine belt tension tunable arrangement
Technical field
The utility model belongs to field of mechanical technique, designs a kind of tensioner tunable arrangement, particularly is applied to the belt tension tunable arrangement on the drilling machine.
Background technology
As everyone knows, drilling machine is when work, and drill bit is realized cutting and tapping by the rotation of main shaft, finishes feed by moving down of main shaft again.In existing drilling machine, the rotation of main shaft is to realize by the belt gear that is connected with motor.Belt gear is generally worm reduction gear, be fixed with connecting plate at the main spindle box sidepiece, and worm reduction gear and motor is fixed on the connecting plate.Motor is connected with cone pulley on the worm reduction gear by belt, and main shaft links to each other with another cone pulley on the worm reduction gear by belt, just can drive the rotation of main shaft like this by motor.Drilling machine is after working long hours, and becoming flexible can appear in the belt between main shaft and the worm reduction gear, and just need carry out tensioner again to belt this moment.Because connecting plate is direct by being bolted to the main spindle box sidepiece, when regulating or change belt, will prize whole connecting plate like this, accuracy is low, poor stability, and waste time and energy.
Summary of the invention
The purpose of this utility model is to exist above-mentioned problem at existing drilling machine, the drilling machine belt tension tunable arrangement that provide a kind of and regulate and control conveniently, accuracy is high.
The purpose of this utility model can realize by following technical proposal: a kind of drilling machine belt tension tunable arrangement, be arranged on the main spindle box of support body, described main spindle box sidepiece is equipped with the connecting plate that is used for fixing motor and worm reduction gear, described worm reduction gear has driving shaft and driven shaft, described driving shaft links to each other by belt with motor, driven shaft links to each other by belt with main shaft, it is characterized in that, this device comprises that four connectors and four holders and described holder are symmetricly set on the both sides of the same end of main spindle box, described connector the inner is plugged on the corresponding holder, the outer end is connected on the connecting plate, all be interspersed with adjusting bolt and described adjusting bolt the inner on described each holder and contact with connector the inner, described holder sidepiece also is provided with clamping screw and described clamping screw the inner is resisted against on the connector.
When the belt tension between needs adjusting main shaft and the worm reduction gear is spent, earlier clamping screw is unclamped, back and forth move axially in holder by rotating adjusting bolt promotion connector again, thus the spacing between control worm reduction gear and the main shaft, the tensioner degree of control belt.After adjustment finishes, again clamping screw is screwed, thereby connector is locked on the holder, so just make connecting plate to move again.
In above-mentioned drilling machine belt tension tunable arrangement, described connector outer end is fixed on the connecting plate by nut.
In above-mentioned drilling machine belt tension tunable arrangement, described connector is the diameter of shaft-like and described connector greater than the diameter of regulating bolt.
In above-mentioned drilling machine belt tension tunable arrangement, described four holder lines are arranged and are formed " mouth " font.Can guarantee like this to be fixed on and keep stability when motor on the connecting plate and worm reduction gear are installed.
Compared with prior art, this drilling machine belt tension tunable arrangement is by being provided with four holders at the main spindle box sidepiece, thereby and intert by four connectors and in holder, to support whole connecting plate, regulate the stroke of connector in holder by regulating bolt simultaneously, thereby the spacing between control worm reduction gear and the main shaft, the tensioner degree of control belt, but also pin connector by clamping screw, make that connecting plate can't move again behind the tensioner degree adjust belt, regulation and control are convenient, high, the good stability of accuracy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a plan structure schematic diagram of the present utility model.
Among the figure, 1, support body; 2, main spindle box; 21, holder; 3, connecting plate; 4, motor; 5, worm reduction gear; 7, connector; 8, clamping screw; 9, regulate bolt; 10, nut; 11, cone pulley; 12, belt; 13, main shaft.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, this drilling machine belt tension tunable arrangement is arranged on the main spindle box 2 of support body 1, at main spindle box 2 sidepieces connecting plate 3 is installed, on connecting plate 3, is fixed with motor 4 and worm reduction gear 5, and motor 4 is connected by belt 12 with worm reduction gear 5.
Drill press spindle 13 runs through main spindle box 2 and has cone pulley 11 in main shaft 13 ends, worm reduction gear 5 has driving shaft and driven shaft and driving shaft perpendicular to driven shaft, all be provided with cone pulley 11 on driving shaft and motor 4, driven shaft and the main shaft 13, and connect by belt 12 respectively.The rotation of motor 4 can make after by worm reducer main shaft 13 also rotate together, and the deceleration of main shaft 13 greatly reduces.
This device comprises that four are the both sides that shaft-like connector 7 and four holders 21 and four holders 21 are symmetricly set on main spindle box 2 one ends, and four holder 21 lines are arranged and formed " mouth " fonts.Each holder 21 all has large through-hole and the small through hole that is on the same axial line, and each connector 7 the inner all is plugged in the large through-hole on the corresponding holder 21, and connector 7 outer ends all are fixed on the connecting plate 3 by nut 10.Also be provided with on each holder 21 and regulate bolt 9 and regulate bolt 9 the inners and intert in small through hole and can contact with connector 7 the inners, regulate bolt 9 and be threaded with holder 21, the diameter of connector 7 is greater than the diameter of adjusting bolt 9.Be provided with clamping screw 8 and clamping screw 8 the inners are resisted against on the connector 7 at each holder 21 sidepiece, clamping screw 8 is threaded with holder 21, can can't move so that connector 7 is axially fixed in the large through-hole of holder 21 by screwing clamping screw 8.
When belt 12 tensioners between needs adjusting main shaft 13 and the worm reduction gear 5 are spent, earlier clamping screw 8 is unclamped, move in holder 21 by rotating adjusting bolt 9 promotion connectors 7 again, thus the spacing between control worm reduction gear 5 and the main shaft 13, the tensioner degree of control belt 12.After adjustment finishes, again clamping screw 8 is screwed, thereby connector 7 is locked on the holder 21, so just make connecting plate 3 to move again.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
