Description
Technical field
The utility model belongs to the grinding machine technical field, specifically, and particularly a kind of vanelets intrados abrasive belt grinding device.
Background technology
Abrasive belt grinding machine is the grinding machine that utilizes the abrasive band of rapid movement to carry out grinding and polishing as grinding tool.Along with the fast development of grinding machine technology, abrasive belt grinding machine has developed into the finish machining equipment of high efficiency and low-power consumption.Particularly in large size plate, tubing, bar and complex-curved processing, its advantage is particularly evident.Sbrasive belt grinding is to drive the abrasive band motion by driving wheel, and regulating wheel provides the back pressure generation to the contact of workpiece and forms cutting angle by contact wheel or support plate in order to the tensioning abrasive band, finishes the grinding to workpiece.
And be the difficult problem of grinding for the intrados grinding of compressor vanelets always, because the inner arc radius of curvature of this kind blade very little (R5 is following), the radius of curvature of this type of blade of radius ratio of the contact wheel of in the past sbrasive belt grinding is large or a little bit smaller, this can occur grinding less than situation.
Therefore, need a kind of compressor vanelets intrados sbrasive belt grinding grinding machine, solve the difficult problem of this type of vanelets intrados sbrasive belt grinding.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of abrasive belt grinding machine that can carry out grinding to compressor vanelets intrados.
The technical solution of the utility model is as follows: a kind of vanelets intrados abrasive belt grinding device, comprise lathe bed (1), motor (2), driving wheel (3) and abrasive band (4), it is characterized in that: at the top of described lathe bed (1) fitting operation plate (5), the top of this operation panel (5) is provided with First Transition wheel (6) and the second transition wheel (7), First Transition wheel (6) is positioned at upper the place ahead of the second transition wheel (7), these two transition wheels all are contained on the riser (8), and riser (8) fixes with lathe bed (1), between First Transition wheel (6) and the second transition wheel (7), be provided with the low early and high after contact lever that is in tilted layout (9), the front end of this contact lever (9) is equipped with sponge bistrique (10), described sponge bistrique (10) is lower than the second transition wheel (7), and the diameter of sponge bistrique (10) is less than 10mm; At the rear of described lathe bed (1) motor (2) is set, this motor (2) is installed on the riser (8), and be set with driving wheel (3) on the output shaft of motor (2), described driving wheel (3) is connected with First Transition wheel (6), the second transition wheel (7) and sponge bistrique (10) by abrasive band (4).
Because compressor vanelets inner arc radius of curvature is very little, traditional bistrique is difficult to it is carried out grinding.Therefore, the utility model adopts diameter less than the sponge bistrique of 10mm, and this sponge bistrique is easy to machine-shaping, and the sponge bistrique can stretch in the gap of compressor vanelets, thereby realizes the grinding to compressor vanelets intrados.The sponge bistrique is installed on the contact lever, and dismounting is not only convenient but also quick.First Transition wheel, the second transition wheel, sponge bistrique and driving wheel carry out rational layout with the abrasive band, and take full advantage of the lathe bed space, and the spatial volume of compact conformation, complete machine is less so on the one hand, on the other hand, the length in abrasive band strengthens, good heat dissipation effect, long service life.Operation panel is the workbench of grinding, when needing grinding, workpiece is placed on the operation panel, and the drive motors running makes motor drive the abrasive band motion by driving wheel, can carry out grinding to workpiece.
