Abstract
The invention relates to a telescopic bracket for installing a passive abrasive belt wheel of a dual-head belt sander. The telescopic bracket comprises a guide sleeve fixed on a main bracket, wherein the lower end of the guide sleeve is rotatably provided with a telescopic drive screw; the telescopic drive screw is in threaded connection with a nut; the nut is fixed on a telescopic sleeve connecting seat; the telescopic sleeve connecting seat is matched inside the guide sleeve in a sliding manner, and extends out of the upper end of the guide sleeve, and the telescopic drive screw is connected with a screw rotating mechanism. According to the telescopic bracket, the telescopic drive screw is driven to rotate through the screw rotating mechanism, so as to drive the telescopic sleeve connecting seat to move in a straight line, thus, the distance between the connection seat on the telescopic sleeve connecting seat and the main bracket is changed, so that the distance between the passive abrasive belt wheel arranged on the telescopic sleeve connecting seat and the active abrasive belt wheel arranged on the bearing block is changed. Thus, the belt sander can utilize the abrasive belts with various specifications, and the application range of the belt sander is expanded.

Technical field
The present invention relates to the double end belt sander for buffing work-piece, specifically a kind of telescoping shoring column be used to passive abrasive belt wheel is installed.
Background technology
Existing double end belt sander, its structure is to be arranged symmetrically with two cover belt sanding devices at support, every cover belt sanding device comprises two abrasive belt wheels, the abrasive band is enclosed within on two abrasive belt wheels, wherein initiatively abrasive belt wheel links to each other with transmission mechanism, transmission mechanism drives initiatively abrasive belt wheel rotation, and and then drive abrasive band rotation.The shortcoming of this belt sander is that the spacing between two abrasive belt wheels in every cover belt sanding device can't change, and can only use a kind of abrasive band of model specification, and the scope of application of belt sander is little.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of telescoping shoring column be used to passive abrasive belt wheel is installed is provided, this support can change the spacing between passive abrasive belt wheel and the active abrasive belt wheel, in order to can use the abrasive band of Multiple Type specification, enlarges the scope of application of belt sander.
According to technical scheme of the present invention: a kind of telescoping shoring column, comprise the guide pin bushing that is fixed on the main support, the lower end of described guide pin bushing rotatably is equipped with flexible drive lead screw, screw has been threaded on the described flexible drive lead screw, described screw is fixed on the telescopic tube Connection Block, described telescopic tube Connection Block is slidingly fitted in the described guide pin bushing and from the upper end of described guide pin bushing and stretches out, and described flexible drive lead screw links to each other with the screw mandrel rotating mechanism.
Described screw mandrel rotating mechanism comprises gear-box, is fixed with handwheel on the power shaft of described gear-box, is fixed with driving gear on its output shaft, and described driving gear is meshed with driven gear on being fixed on described flexible drive lead screw.
Described gear-box adopts Bevel Gear Transmission, comprises the active bevel gear that is fixed on the described power shaft and is fixed on passive bevel gear on the described output shaft, and described active bevel gear is meshed with described passive bevel gear.
Be fixed with feather key on the described telescopic tube Connection Block, have the keyway that matches with described feather key on the inwall of described guide pin bushing.
Technique effect of the present invention is: the present invention is fixed with guide pin bushing at main support, flexible drive lead screw is installed in guide pin bushing and is threaded in telescopic tube Connection Block on the flexible drive lead screw, drive flexible drive lead screw rotation by the screw mandrel rotating mechanism, and and then drive telescopic tube Connection Block moving linearly, thereby change the Connection Block of telescopic tube Connection Block and the distance between the main support, the distance that is installed in the passive abrasive belt wheel on the telescopic tube Connection Block and is installed between the active abrasive belt wheel on the bearing block is changed, the abrasive band that makes belt sander can use plurality of specifications has enlarged the scope of application of belt sander.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1, Fig. 2, comprise telescopic tube Connection Block 1, flexible drive lead screw 2, screw 3, active bevel gear 4, passive bevel gear 5, gear-box 6, output shaft 7, feather key 8, guide pin bushing 9, driving gear 10, driven gear 11, main support 12, handwheel 13, power shaft 14 etc.
As shown in Figure 1 and Figure 2, the present invention is a kind of telescoping shoring column, be used for installing the passive abrasive belt wheel of double end belt sander, it comprises the present invention is fixed on the initiatively main support 12 on the abrasive belt wheel of double end belt sander, be fixed with guide pin bushing 9 at main support 12, flexible drive lead screw 2 is installed in the guide pin bushing 9, the lower end of flexible drive lead screw 2 is rotatably installed in the lower end of guide pin bushing 9 by bearing, the screw 3 that has been threaded on the flexible drive lead screw 2, screw 3 is fixed on the telescopic tube Connection Block 1.
Telescopic tube Connection Block 1 comprises the Connection Block that is slidingly fitted in the sleeve pipe in the guide pin bushing 9 and is fixed on the sleeve pipe upper end, and Connection Block is used for connecting passive abrasive belt wheel, and the lower end of sleeve pipe is fixed with above-mentioned screw 3, the upper end of sleeve pipe.Be fixed with feather key 8 on the sleeve pipe of telescopic tube Connection Block 1, have the keyway that matches with feather key 8 on the inwall of guide pin bushing 9, the effect of feather key 8 is to guarantee that telescopic tube Connection Block 1 can not rotate along guide pin bushing 9 moving linearlies.
Flexible drive lead screw 2 links to each other with the screw mandrel rotating mechanism, drives rotation by the screw mandrel rotating mechanism.The screw mandrel rotating mechanism comprises gear-box 6, is fixed with handwheel 13 on the power shaft 14 of gear-box 6, is fixed with driving gear 10 on its output shaft 7, and driving gear 10 is meshed with driven gear 11 on being fixed on flexible drive lead screw 2.
Gear-box 6 adopts Bevel Gear Transmission, comprises the active bevel gear 4 that is fixed on the power shaft 14 and is fixed on passive bevel gear 5 on the output shaft 7, and initiatively bevel gear 4 is meshed with passive bevel gear 5.
The course of work of the present invention is as follows: rotate handwheel 13, transmission by gear-box 6 drives flexible drive lead screw 2 rotations, and and then drive telescopic tube Connection Block 1 moving linearly be threaded on the flexible drive lead screw 2, thereby change the Connection Block of telescopic tube Connection Block 1 and the distance between the main support 12.Because main support 12 is installed on the bearing block of active abrasive belt wheel of double end belt sander, the passive abrasive belt wheel of double end belt sander is installed on the Connection Block of telescopic tube Connection Block 1, thereby change the distance between passive abrasive belt wheel and the active abrasive belt wheel, the abrasive band that makes belt sander can use plurality of specifications has enlarged the scope of application of belt sander.
