Abstract

The utility model provides a pneumatic sander which comprises a wind wheel 2, a sanding tool and a gear transmission The pneumatic sander is characterized in that one end of the wind wheel 2 is connected with compressed air through a valve 1, the other end of the wind wheel 2 is connected with a gear II 11 through a shaft I 12, the gear II 11 and the shaft I 12 are fixed on a box body 15 through bearings, the gear II 11 is meshed with a gear I 6 which is connected with a shaft II 14 and fixed on the box body 15 through bearings, the shaft II 14 is connected with the sanding tool 9 and a tool clamping chuck 8, parts are fixed by a part clamper 4 which can slide along the axis direction of the box body 15. The pneumatic sander is compact in structure, convenient to use, simple to maintain, low in manufacturing cost; and the weld fillet can be sanded uniformly, looks attractive, and is reliable in quality.

Description

A kind of pneumatic sander
Technical field
The present invention relates to a kind of pneumatic milling tools that the fillet of pipe fitting high-frequency induction brazing is polished.
Background technology
At present, mainly adopt wind milling cutter, emery wheel manual grinding for weld defects such as the irregular fillet that produces in the pipe fitting high-frequency induction brazing, overlaps, the method is because the polishing tool High Rotation Speed, manual operations is unstable and cause the mother metal matrix damage, the weld seam height that polish differs, and affects attractive in appearance and weld strength, and this class methods air exercise grinder people's technical skill relies on higher, production efficiency is low, and is of poor quality.
Summary of the invention
Purpose of the present invention: provide the weld defects such as a kind of irregular fillet to the pipe fitting high-frequency induction brazing, overlap to carry out the pneumatic tools of mechanical grinding.
The purpose of the invention is to realize by following technical scheme: a kind of pneumatic sander comprises that wind turns, gear drive, polishing tool; Wind turns from an end and connects compressed air by valve, the other end connects gear 2 11 by axle 1, gear 2 11 is fixed on the casing by bearing with axle 1, gear 2 11 and gear one 6 engagements, gear 1 links together with axle 2 14 and is fixed on the casing by bearing, axle 2 14 connects polishing tool and cutter holder cutter clamping dish 8, and part binding clasp 4 retaining elements can slide along the casing axis direction.
The advantage of the invention is: this pneumatic sander is by connecting compressed air, the band cutter moves in a circle around pipe fitting, polishing soldering fillet and overlap, and cutter and casing can be done feed motion along axis direction during work, can intuitively observe the polishing situation, the polishing amount is convenient to control; For the pipe fitting high-frequency induction brazing, there is no professional milling tools in the prior art, yet this instrument adopts cutter around part rotation mode polishing leg, compact conformation, easy to use, safeguard simple, low cost of manufacture; Simultaneously can effectively guarantee leg grinding homogeneity, attractive in appearance, reliable in quality.
Description of drawings
Fig. 1 is the structural representation of the pneumatic sander of the utility model.
The specific embodiment
Fig. 1 is pneumatic sander structural representation, in the utility model preferred embodiment pneumatic sander mainly by turned 2 by valve 1, wind, slide rail 3, part binding clasp 4, gear 1, gear 2 11, cutter clamping dish 8, polishing tool 9, casing 15 etc. form; Wind turns 2 by valve 1 connection compressed air, and band moving axis 1 rotates, and axle 1 connects gear 2 11 by key, and is fixed on the casing 15 by bearing; Gear 2 11 connects gear 1, gear 1 is fixed on the axle 2 14, axle 2 14 is fixed on the casing 15 by bearing, axle 2 14 connects cutter clamping dish 8, axle 2 14 welds together with gear 1 and knife rest plate 8, and cutter is pressed abd fixed on the knife rest plate by bolt, and part binding clasp 4 is by the spring compression retaining element, and can move along the axis direction of the slide rail on the casing 15, realize feed motion.
The above is preferred embodiment of the present utility model only, is not to limit application range of the present utility model; All other do not break away from the equivalence of finishing under the essence that the utility model discloses and change or modify, and all should be included in following claims scope.
