Abstract
The utility model belongs to the technical field of machining equipment, and particularly relates to a pneumatic grinder for the inner wall of a workpiece. The pneumatic grinder for the inner wall of the workpiece comprises a pneumatic motor, a connector is arranged on an output shaft of the pneumatic motor, an inserting hole is formed in the axis of the outer end of the connector, an extension rod is connected into the inserting hole in an inserting mode, a tool bit is arranged at the front end of the extension rod, and the tool bit comprises a grinding end socket which is placed at the front end and a connecting rod which is placed at the rear end and is fixedly connected with the extension rod. The pneumatic grinder for the inner wall of the workpiece is simple in structure and small in size, the grinding range is expanded through the arranged extension rod and the tool bit which is fixedly connected with the extension rod, and the pneumatic grinder is suitable for grinding the inner wall of the workpiece with the small hole diameter and the large depth.
Description
Technical field
The utility model machining equipment technical field, relates in particular to the pneumatic Carving grinder of a kind of workpiece inwall.
Background technology
In field of machining, often relate to the polishing to workpiece inside and outside wall, in the process of polishing, remove burr so that its roughness meets the demands.For the situation of polishing outer wall, owing to can directly externally processing, therefore operation realizes than being easier to.And for polishing inwall situation, due to needs sanding apparatus stretch into inside workpiece make processing have difficulties.Particularly, workpiece that the degree of depth large little for some apertures, carves mill to its inwall and has especially larger difficulty.
Utility model content
The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, be applicable to the workpiece of the large degree of depth in small-bore to carry out the pneumatic Carving grinder of workpiece inwall that inwall is carved mill.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: the pneumatic Carving grinder of workpiece inwall comprises air motor, on its output shaft, be provided with connector, the place, axle center of described connector outer end is provided with jack, in described jack, be plugged with extension rod, front end at described extension rod is provided with cutter head, and described cutter head comprises the connecting rod affixed with described extension rod that grinds termination the quarter that is positioned at front end and be positioned at rear end.
Advantage of the present utility model and good effect are: Carving grinder of the present utility model is simple in structure, volume is small and exquisite, by extension rod and affixed cutter head are with it set, have expanded the scope of carving mill, are applicable to the mill processing at quarter to the workpiece inwall of the large degree of depth in small-bore.
Preferably: it is cylindrical grinding termination described quarter.
Preferably: grinding termination described quarter is taper.
Preferably: described connecting rod adopts the affixed mode of welding to be connected with described extension rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is extension rod and the structural representation of carving mill end portion in Fig. 1.
In figure: 1, air motor; 2, connector; 3, extension rod; 4, cutter head.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the utility model comprises air motor 1, is provided with connector 2 on its output shaft, and place, the axle center of connector 2 outer ends is provided with jack, is plugged with extension rod 3 in this jack, at the front end of extension rod 3, is provided with cutter head 4.
In order to adapt to the needs of different workpieces, different inner wall shape, the combination of at least two kinds of extension rods of this Carving grinder setting 3 and cutter head 4, can change use.The first is that mill at quarter termination is cylindrical, grinds termination the quarter of this kind of shape and is applicable to polishing sliding inwall quarter, and process velocity can suitably be put soon; In second, be that mill at quarter termination is taper, grind the edge that termination is applicable to processing inwall the quarter of this kind of shape, the edge formation chamfering of all right processing work, process velocity need to suitably slow down.
