Abstract
The utility model discloses a multi-purpose elastic movable thimble, which includes a thimble casing (1), a casing cover (2), bearings (3) and a main shaft (4), wherein the bearings (3) are arranged at the front end inside the thimble casing (1); the main shaft (4) is installed in the thimble casing (1) through the inner diameters of the bearings (3); and the casing cover (2) is in threaded connection with the thimble casing (1). The multi-purpose elastic movable thimble is characterized in that a disk spring leaf (5) is arranged between the two bearings (3); a seal ring (6) is arranged in the casing cover (2); a needle bearing (7) is arranged at the tail end of the main shaft (4); a centre drill device (8) is arranged at the front end of the main shaft (4); and a bearing cap (9) is arranged at the rear end of the thimble casing (1). Compared with the present processing method, the multi-purpose elastic movable thimble provided by the utility model has the advantages of simple structure, convenience for use, time and labor conservation, high work efficiency and improved processing quality.
Description
Technical field
The utility model relates to a kind of improvement of active thimble, and is specifically a kind of many with the active thimble of elasticity, is applicable to machining slender shaft and shaft-like workpiece centering usefulness.
Background technology
At present, be to bore before the turning axle class with the drill point Clamping Center, first centering then withstands centre bore processing with active thimble; Above-mentioned processing method though generally apply, also has following deficiency at present: the one, and operation is many; Troublesome poeration is wasted time and energy, and production efficiency is low; The 2nd, when the turning slender axles, workpiece heating elongation strain influences crudy; The 3rd, the butter in the no oil sealing in the thimble, bearing, the back that is heated is prone to outflow and pollutes workpiece.
Summary of the invention
It is a kind of simple in structure, easy to use, time saving and energy saving that the purpose of the utility model is to provide, and work efficiency is high, improves the many with the active thimble of elasticity of crudy.
For reaching above purpose, the technical scheme that the utility model is taked is: these are many with the active thimble of elasticity, are made up of thimble housing, case lid, bearing, main shaft; Front end in the thimble housing is established bearing; Main shaft is installed in the thimble housing through the internal diameter of bearing, and case lid and thimble housing is characterized in that establishing disc spring film between two bearings with being threaded; In case lid, establish sealing ring; End at main shaft is established needle bearing, and front end is established the centre drill device, and bearing cap is established in the rear end of thimble housing.The utility model is also implemented through following measure; Described centre drill device is made up of centre drill, adapter sleeve, brill housing, and the internal thread of adapter sleeve one end is screwed on the external screw thread of thimble housing front end; The other end is established external screw thread and is connected with the internal thread that bores housing, and centre drill is installed in and bores in the housing.When using the utility model centering, centre drill is packed into bore in the housing earlier, fix with the external screw thread of adapter sleeve front end; Then internal thread is screwed on the thimble housing, punching after finishing is unloaded the centre drill device; Withstand workpiece with the active thimble of elasticity and process,, guarantee that promptly tail spindle is to enough elasticity is arranged because of having adopted disc spring film between two bearings; Can when workpiece turning is out of shape, do axially automatically adjustment again, make not reason processing heating and being out of shape of workpiece.
The beneficial effect of the utility model is: compare with present processing method, have simple in structurely, easy to use, time saving and energy saving, work efficiency is high, improves the advantage of crudy.
