Description

A kind of bent axle polishing machine

(1), technical field:

The utility model relates to the bent axle process equipment, is specifically related to a kind of bent axle polishing machine.

(2), background technology:

Bent axle is in process, because tolerance range is less, especially the part bent axle product diameter of axle is adding man-hour, and tolerance is near the high limit of size, after passing through nitriding furnace surface cure process again, diameter of axle size produces to be increased, and in addition, the bent axle surface roughness that has is poor, after these reasons produce, can't meet the quality requirement, just require to do over again, the product after doing over again is difficult to reach its intended purposes, particularly connecting rod footpath size is little adds and the surface roughness difference, accuracy is had relatively high expectations, and more is difficult to do over again, and the product reliability after doing over again is difficult to guarantee, wasted the time again, reduced efficiency, increased cost, and percent defective is higher.

(3), summary of the invention:

The purpose of this utility model is to provide a kind of bent axle polishing machine, and is easy to operate, not only reduced cost, guaranteed reliability of products, and increased substantially labor productivity.

For achieving the above object, a kind of bent axle polishing machine of the utility model comprises a body, high-speed electric expreess locomotive and abrasive band, it is characterized in that: this belt sander also comprises guide rail, rear supporting plate, rear roller, planker, planker handle, abrasive band driving wheel, abrasive band driven pulley, bow arm and the abrasive band handle on preceding supporting plate, front wheel, the bed body; Described high-speed electric expreess locomotive is fixed on the electric baseboard, and electric baseboard is fixedlyed connected with planker one end, and the planker other end and planker handle are fixed, and planker is fixed by preceding supporting plate and rear supporting plate and a bed body respectively; Described front wheel is fixedlyed connected with the rear roller support with the front wheel support by ball bearing respectively with rear roller, and front wheel support and rear roller support are fixed on the below of planker, and front wheel is movable fixing with the guide rail on the bed body, and rear roller is movable fixing with the bed body; Described abrasive band driving wheel is fixed on the motor shaft of high-speed electric expreess locomotive, and with the bow arm an end fix, the other end of bow arm is fixedlyed connected with the abrasive band driven pulley, the abrasive band activity is fixed on abrasive band driving wheel and the abrasive band driven pulley, the upper end of handle and abrasive band driven pulley are fixed, and the other end is movable fixing by ball bearing and abrasive band driving wheel; Described top being fixed on the body.

In technique scheme, the planker activity is fixed on the guide rail of a body, and because ball bearing has been adopted in planker and guide rail contact position, reduced the friction between guide rail and planker, drive planker by handle and move, thereby drive the abrasive band motion, can process any part of bent axle, operate lightly, improved production efficiency.Motor has adopted high-speed electric expreess locomotive, has increased the abrasive band linear velocity, makes the bent axle product roughness of doing over again satisfy required precision after processing, has guaranteed its reliability, has reduced cost.
