Abstract
The utility model belongs to chuck class, and specifically a kind of doublet contact chuck claw, is characterized in that the side conical surface is put together by three sections of taper seats, forms two splicing lines, and the taper seat that is wherein positioned at both sides is identical, and stage casing taper seat is larger.When 3 doublet contact chuck claws in being distributed in chuck shell clamp minimum or maximum gauge work package, its side taper seat is face with chuck shell internal conical surface and contacts, contact stress is little, clamp precision is high, when clamping diameter mediates the work package of scope, the internal conical surface of its two splicing lines and chuck shell forms doublet contact, effectively shares contact stress, improves contact strength and clamping position precision.
Description
Technical field
The utility model belongs to chuck class part, specifically a kind of doublet contact chuck claw.
Background technology
Existing chuck kind is a lot, be widely used in tool industry, but its side conical surface of the chuck claw that existing chuck is joined is single taper seat, 3 chuck claw clamping minimum diameter work package (drill bits in being distributed in chuck shell, screw tap etc.) time, claw side taper seat and chuck shell inner conical surface are fitted completely, contact area is maximum, when clamping larger diameter work package, claw side taper seat with shell internal conical surface only for single line contacts, contact strength is not high enough, and affect chuck claw clamping position precision, easily produce eccentric, be unfavorable for the normal work of chuck.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of doublet contact chuck claw is provided.
Technical solutions of the utility model are as follows:
The utility model is a kind of doublet contact chuck claw, it is characterized in that: the chuck claw side conical surface is put together by three sections of taper seats, form two splicing lines, the taper seat that is wherein positioned at both sides is identical, stage casing taper seat is larger, when 3 doublet contact chuck claws in being distributed in chuck shell clamp minimum diameter work package, the internal conical surface of the taper seat of its both sides and chuck shell is fitted completely, when clamping maximum gauge work package, taper seat in the middle of it and the internal conical surface of chuck shell are fitted completely, when clamping diameter mediates the work package of scope, the internal conical surface of two splicing lines of chuck claw and chuck shell forms doublet contact.
The beneficial effects of the utility model are:
Use the utility model, when clamping minimum or maximum gauge work package, doublet contact chuck claw is face with chuck shell inner conical surface and contacts, contact stress is little, clamping position precision is high, when clamping diameter mediates the work package of scope, and two splicing lines of doublet contact chuck claw and the internal conical surface formation doublet contact of chuck shell, effectively share contact stress, improved contact strength and clamping position precision.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart
Fig. 2 is the installation diagram of the utility model in chuck
In figure, doublet contact chuck claw 1, chuck shell 2.
The specific embodiment
Below in conjunction with accompanying drawing, describe the utility model embodiment in detail
As Fig. 1, shown in Fig. 2, a kind of doublet contact chuck claw, it is characterized in that: the side conical surface of chuck claw 1 is put together by three sections of taper seats, form two splicing lines, the taper seat that is wherein positioned at both sides is identical, stage casing taper seat is larger, when being installed on interior 3 the uniform doublet contact chuck claw clamping minimum diameter work packages of chuck shell 2, the internal conical surface of the taper seat of its both sides and chuck shell 2 is fitted completely, when clamping maximum gauge work package, taper seat in the middle of it and the internal conical surface of chuck shell 2 are fitted completely, when clamping diameter mediates the work package of scope, the internal conical surface of its two splicing lines and chuck shell forms doublet contact.
The course of work of the present utility model is: as shown in Figure 2, when adjusting is installed on interior 3 uniform doublet contact chuck claws, the 1 clamping minimum diameter work package of chuck shell 2, the internal conical surface of the taper seat of its both sides and shell 2 is fitted completely, when clamping maximum gauge work package, taper seat in the middle of it and the internal conical surface of shell 2 are fitted completely, two kinds of situations are face contact, contact stress is little, clamping position precision is high, when clamping diameter mediates the work package of scope, two splicing lines that its different conical surfaces form and the internal conical surface formation doublet contact of shell 2, effectively share contact stress, improve contact strength and clamping position precision.
