Abstract

The utility model relates to an abrasive belt machine, especially an abrasive belt swing device of the abrasive belt machine, which comprises two swing pieces, wherein the two swing pieces are arranged on both ends of a driven wheel of the abrasive belt machine and enable the driven wheel to deviate a scheduled angle corresponding to the axial direction of a drive wheel. When abrasive belts which are sheathed on the outer of the driving wheel and the driven wheel move on the driven wheel to touch the scheduled swing pieces, the deviation angle of the driven wheel which is corresponding to the axial direction of a drive wheel is changed, the abrasive belts are moved naturally towards the other end of the driven wheel and the effect that the abrasive belts are moved in a reciprocating mode on the driven wheel is achieved. The utility model can reduce working burdens of operating staffs, and prolongs the service life of the abrasive belts.

Description

The abrasive band rocking equipment of belt sander

Technical field

The utility model relates to a kind of belt sander, particularly a kind of abrasive band rocking equipment of belt sander.

Background technology

Be pivoted with a relative driving wheel and a driven pulley on the board of existing belt sander, the abrasive band is to be nested with in the driving wheel and the driven pulley outside, when driving wheel is driven by motor and during rotation, the abrasive band that is tight state can be dragged, the operating personnel abrasive band of workpiece can being conflicted utilizes the abrasive band to carry out grinding work-piece.Because the abrasive band is when grinding work-piece, abradant surface can wear away gradually, and abrasive band face abrasion are uneven to be damaged in advance in order to avoid, and when operating personnel utilized the belt-sanding workpiece, travelling workpiece at any time will cause the burden of operating personnel on working thus.

Therefore, the technical staff in capable territory develops the belt sander that can make the reciprocal move left and right in abrasive band gradually in recent years, can alleviate the burden in operating personnel's work, but, so far, existing can make the belt sander structure of the reciprocal move left and right in abrasive band comparatively numerous and diverse, make that cost of manufacture can't effectively reduce, practical value can't effectively improve.

The utility model content

At above-mentioned deficiency, main purpose of the present utility model provides a kind of simple in structure, effective, can reduce cost of manufacture, has the abrasive band rocking equipment of the belt sander of practical value.

For achieving the above object, the abrasive band rocking equipment of the utility model belt sander is by a frame, a driving wheel, a driven pulley and be nested with at the members such as an abrasive band in this driving wheel and the driven pulley outside and formed, this abrasive band rocking equipment is arranged on the frame, include two swing components, be hubbed on relatively on this frame and be articulated in therebetween, with so that this driven pulley axial dipole field predetermined angular of driving wheel relatively for driven pulley; On driven pulley, move and when touching predetermined swing component when this abrasive band, can change the relative drive sprocket axle of this driven pulley to deviation angle, this abrasive band is moved towards the driven pulley other end naturally, reach the effect that this abrasive band is moved back and forth on driven pulley.

Adopt the cooperation of swing component, moving part and pneumatic control valve, make the relative drive sprocket axle of driven pulley to reciprocally reciprocal transformation of deviation angle, formation makes abrasive band move left and right reciprocally on driven pulley, simplified the structure of belt sander abrasive band rocking equipment, improved operating efficiency, reduced cost of manufacture, alleviated burden in operating personnel's work, prolonged service life in abrasive band.

The specific embodiment

By Figure 1 and Figure 2 as can be known, the abrasive band rocking equipment 10 of the utility model one preferred embodiment is arranged on the belt sander 12, and this belt sander 12 comprises a frame 14, be arranged on a driving wheel 16, the driven pulley 18 on this frame 14 and be looped around the abrasive band 20 and original members such as motor, air-pressure equipment (not shown) in driving wheel 16 and driven pulley 18 outsides.This frame 14 is made up of a pedestal 22 and a support 24, and this driving wheel 16 is hubbed on the pedestal 22, and this driven pulley 18 is hubbed on the support 24.

This abrasive band rocking equipment 10 is made up of two

swing components

26,28, two moving

parts

30,32 and a pneumatic control valve 34.This two

swing component

26,28 has a disk body 36 respectively and is based in a driving lever 38 of disk body 36 bottoms, respectively this disk body 36 is to be erected at support 24 top sides swingably, this driven pulley 18 is to be articulated between two disk bodies 36, respectively the pivoting point 361 of these disk body 36 pivot joint supports 24 is separated by one apart from a with the axle center 181 of driven pulley 18, and respectively this driving lever 38 is that opening 40 set on the support 24 extends to support 24 bottom sides.This two moving part the 30, the 32nd is located at support 24 bottom sides pivotly relatively respectively with corresponding each driving lever 38 of an end, this pneumatic control valve 34 is three mouthfuls of common two-position valves, be installed in these support 24 bottom sides and connect air-pressure equipment, two

touch poles

42,44 are the other end of corresponding two moving

parts

30,32 respectively.

Fig. 3 and shown in Figure 4, the manner of execution of abrasive band described in the utility model rocking equipment 10 is as follows: when this belt sander 12 does not operate, the air pressure of this air-pressure equipment can make the touch pole 42 pushing and pressing moving parts 30 of pneumatic control valve 34, make the driving lever 38 of this swing component 26 be rocked to the position of resisting opening 40 inner edges, the suitable angle of these driven pulley 18 relative driving wheel 16 axial dipole fields, when these belt sander 12 runnings, this abrasive band 20 can be moved towards swing component 28 directions in operation process naturally.

Fig. 5 and shown in Figure 6, when swing component 28 is touched in this abrasive band 20, abrasive band 20 in this revolution just can drive swing component 28 and swing along gyratory directions, with so that the driving lever 38 of this swing component 28 can resist the other end inner edge of opening 40, thus, utilize the mode of lever principle, this moving part 32 can be subjected to the promotion of driving lever 38 and pivot, form this touch pole 42 of compacting, then this pneumatic control valve 34 can move and touch pole 44 is released, impel moving part 32 to pivot, can promote this touch pole 44, swing component 28 is swung towards opposite side, like this, this driven pulley 18 is the axially oppositely skew of driving wheel 16 relatively, and this abrasive band 20 is moved towards swing component 26 directions in operation process.

As from the foregoing, abrasive band described in the utility model rocking equipment 10 utilizes the cooperation of swing component simple in

structure

26,28, moving

part

30,32 and pneumatic control valve 34, can make the axial reciprocally reciprocal transformation of deviation angle of the relative driving wheel of this driven pulley 18 16, formation makes this abrasive band 20 move left and right reciprocally on driven pulley 18, can reduce burden in operating personnel's work, prolong service life in abrasive band.

The two moving part ends that can produce leverage in the utility model also can directly be connected with the touch pole of pneumatic control valve, are subjected to the driving of swing component and swing, form and impel another swing component to swing towards different directions.Above-mentioned equalization of making according to technical solutions of the utility model changes and revises, all belong to the protection of the utility model claim scope.
