Description

The fuselage governor motion of belt sander

Technical field

The utility model belongs to field of mechanical technique, the fuselage governor motion on particularly a kind of belt sander.

Background technology

Belt sander has advantages such as the polishing performance is good, fineness height, is used widely in industries such as five metals, hot-water heatings at present.In belt sander, the abrasive band is socketed on driving wheel and the driven pulley, and driving wheel is to be driven by belt pulley by motor to rotate.In the polishing machine use, position difference, the difference of workpiece size, the workpiece polishing requirements difference of polishing owing to surface of the work need the abrasive band that the cutting angle of workpiece is had certain variation, to obtain best polishing effect.Therefore workpiece need contact with the abrasive band at moving runner place in the polishing machine sometimes, and sometimes in workpiece and the polishing machine abrasive band between two moving runners contact more suitable.In existing polishing machine, because fuselage is fixed, therefore in order to make between workpiece and the polishing machine fuselage with a suitable cutting angle job, the workman often is in a factitious position and operates, the labour intensity of its work is big, and has influence on the quality of finish of workpiece to a certain extent.

Summary of the invention

The purpose of this utility model is in order to overcome existing the problems referred to above in the present belt sander, and a kind of fuselage governor motion of belt sander rational in infrastructure, easy to adjust is provided.

For achieving the above object, the utility model has adopted following technical proposal: the fuselage governor motion of this belt sander comprises support and the axle bed that is fixed on the support, a driven shaft runs through axle bed, one end axial restraint of driven shaft driven pulley, the other end runs through fuselage, also be provided with driving shaft on the fuselage, driving shaft runs through fuselage, and be arranged in parallel with driven shaft, driving wheel is being fixed in the end of driving shaft, and an adjustable plate is arranged on the axle bed, has adjustment hole on the adjustable plate, an adjustment screw is passed adjustment hole, connects with fuselage by screw thread.

In the fuselage governor motion of this belt sander, regulate its angle by the rotation of fuselage on driven shaft, to be fit to the polishing needs of different workpieces.After the fuselage angle mixes up, as long as tighten adjustment screw.

Sometimes, also be provided with a regulating wheel on the polishing machine, so that the replacing in abrasive band.At this moment, as long as a regulating shaft parallel with driving shaft is set on fuselage, the end that regulating wheel is axially fixed at regulating shaft gets final product.

Advantage of the present utility model is:

1, because driving wheel, driven pulley and regulating wheel on the abrasive band all are connected on the fuselage by its rotating shaft,, can not influence the rate of tension in abrasive band so three wheel relative positions are constant in the fuselage adjustment process.

2, utilize adjustment screw that fuselage is rotated and regulate its angle, easy to operate.

3, after polishing machine adopted structure of the present utility model, the workman can obtain best polishing effect according to different its cutting angles of regulating arbitrarily of polishing workpiece; Gu the time also alleviated working strength of workers, increase work efficiency.

The specific embodiment

As shown in Figure 1, the fuselage governor motion of the belt sander that the utility model provides is loaded on the support 1 of polishing machine, and it comprises parts such as axle bed 2, driven shaft 3, driven pulley 4, driving shaft 5, driving wheel 6, regulating shaft 7, regulating wheel 8, fuselage 9, adjustable plate 10.Axle bed 2 is fixed on the support 1.As shown in Figures 2 and 3, fuselage 9 is triangular in shape, and driven shaft 3, driving shaft 5 and regulating shaft 7 are arranged at the place, three bights of fuselage 9 respectively.Driving wheel 6, driven pulley 4 and regulating wheel 8 all are positioned at the same side of fuselage 9, and abrasive band 14 is socketed on these three wheels.

As Fig. 2 and shown in Figure 4, adjustable plate 10 is arranged on the axle bed 2, adjustment hole 11 is circular arc in the adjustable plate 10, and adjustment screw 12 is passed this adjustment hole 11, and connects with fuselage 9 by screw thread.Because fuselage 9 is socketed on the driven shaft 3, so fuselage 9 can rotate.But utilize adjustment screw 12 to be screwed in the fuselage 9, fuselage 9 and adjustable plate 10 are close together after, fuselage 9 will maintain static.Obviously, when needs are regulated the angle of polishing machine fuselage 9,, just can rotate as long as unclamp adjustment screw 12.

As shown in Figure 1 and Figure 4, the outer end of driven shaft 3 also is provided with spring 13, and spring 13 roof pressures are on fuselage 9.The effect of spring 13 is that fuselage 9 and adjustable plate 10 are fit together, and prevents that adjustment screw 12 from unclamping rear body 9 positions and taking place to change significantly, so that the adjusting of fuselage 9 operation.

As shown in Figure 1, in the present embodiment, regulating wheel 8 is the rates of tension that are used to regulate abrasive band 14.When polishing machine normally used, regulating wheel 8 made abrasive band 14 keep tensioning state; When needs are changed abrasive band 14,, abrasive band 14 is eased out by changing the position of regulating shaft 7 and regulating wheel 8.Because regulating shaft 7 is arranged on the fuselage 9,, also remain unchanged with regard to the rate of tension that makes abrasive band 14 so when fuselage 9 is regulated, can not have influence on the position of regulating shaft 7 and regulating wheel 8.

As shown in Figure 1, be provided with belt pulley 15 at the opposite side of driving shaft 5, the motor 17 of polishing machine connects with belt pulley 15 by belt 16.By the transmission of belt 16, whole polishing machine is turned round under the drive of motor 17.

As shown in Figure 3, in order to cooperate the adjusting of fuselage 9, also be provided with a base plate 20 between polishing machine motor 17 and support 1, this base plate 20 is hinged with support 1, and motor 17 is fixed on the base plate 20, and the edge of base plate 20 also is provided with a positioner.In the present embodiment, above-mentioned positioner is formed with a hinged positioning strip 19 and the dog screw 18 of support 1 by one, and the pilot hole 21 of a bar shaped is arranged in the positioning strip 19, and dog screw 18 passes this pilot hole 21, and connects with above-mentioned base plate 20.After fuselage 9 adjustings are finished, need do corresponding adjusting to the position of motor 17, to guarantee that belt 16 is in suitable rate of tension.After adjusted motor 17 positions, screwed in place screw 18 just can make the position of the motor 17 on base plate 20 and the base plate 20 be maintained fixed.
