Abstract
The utility model provides a fixture, including axis body and nut, axis body structure as an organic whole, the first part of is the circular cone, and the latter half is the cylinder, the circular cone is opened along the axial lead direction has polygon centre gripping chamber, and the circular cone front end has an opening, the nut is located the tail end and cylinder handing -over department of circular cone. The utility model has the advantages of with positive effect be: the mode of doing all can is given to the three direction of material jointly to the adoption, has reduced the skew at material center and anchor clamps center, makes the material of processing out more accurate, the first part of is cone structure, and it is tight that the front end makes anchor clamps can be applicable to the clamp of unidimensional material not, presss from both sides more easily in addition, outside screw thread design collocation taper nut presss from both sides tightly more firmly.
Description
Technical field
This utility model belongs to apparatus processing field, especially relates to one and fixes to clamp fixture.
Background technology
The clamping device of the existing material bar-shaped for cylinder or polygon, some employing column structures, then with bolt, it is fixed again.So due in insertion apparatus the size of material be certain to less than device inside dimension, then with bolt, it is fixed, the central axis of material will offset with the central axis of clamping device, causes centralized positioning deviation occur, brings loss to production.
Summary of the invention
In view of this, this utility model is directed to a kind of stationary fixture, it is possible to accurate, stable location, it is prevented that owing to positioning the loss being forbidden to cause.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that a kind of stationary fixture, including axis body and nut, axis body is structure as a whole, first half is circular cone, and latter half is cylinder, and described circular cone has polygon holding chamber along direction of axis line, and conical nose has opening, described nut to be positioned at tail end and the cylinder junction of circular cone.
Further, described conical outer wall is furnished with screw thread.
Further, being taper inside described nut, nut is connected with tapered tread.After material enters holding chamber, nut starts to turn clockwise, and clamps material.
Further, described polygon holding chamber overlaps with axis body axial line.
Further, length and the axis body axial length of described polygon holding chamber are equal, and polygon holding chamber radial dimension in cylinder is equal to polygon holding chamber radial dimension of minima in circular cone.
Further, described circular cone has the opening that end-grain cutting is opened in the past, and opening direction is circular cone radial direction, and opening is vertical with the cross section of axis body.
Further, described opening has 3, is uniformly distributed on circular cone.
Further, described opening axial length is equal with circular cone axial length.
Relative to prior art, stationary fixture described in the utility model has the advantage that
Stationary fixture described in the utility model: adopt three directions of material jointly to the mode of power, reduce the skew of material center and clamp central, make the material processed more accurate；First half is conical structure, and front end makes fixture go for the clamping of different size material, and is easier to folder；External screw-thread design collocation tapered cup nut, clamps more firm.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the stationary fixture schematic perspective view described in this utility model embodiment；
Fig. 2 is the stationary fixture axial section described in this utility model embodiment.
Description of reference numerals:
1-axis body, 2-circular cone, 3-cylinder, 4-nut, 5-polygon holding chamber, 6-opening, 7-screw thread.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1, a kind of stationary fixture, including axis body 1 and nut 4, axis body 1 is structure as a whole, first half is circular cone 2, and latter half is cylinder 3, and described circular cone 2 has polygon holding chamber 5 along direction of axis line, and circular cone 2 front end has opening 6, described nut 4 to be positioned at tail end and cylinder 3 junction of circular cone 2.
Above-mentioned circular cone 2 outer wall is furnished with screw thread 7.
Being taper inside above-mentioned nut 4, nut 4 is threadeded with circular cone 2.
Above-mentioned polygon holding chamber 5 overlaps with axis body 1 axial line.
Length and axis body 1 axial length of above-mentioned polygon holding chamber 5 are equal, and the polygon holding chamber 5 radial dimension in cylinder 3 is equal to polygon holding chamber 5 radial dimension of minima in circular cone 2.
Above-mentioned circular cone 2 has the opening 6 that end-grain cutting is opened in the past, and opening 6 direction is circular cone 2 radial direction, and opening 6 is vertical with the cross section of axis body 1.
Above-mentioned opening 6 has 3, is uniformly distributed on circular cone 2.
Above-mentioned opening 6 axial length is equal with circular cone 2 axial length.
To process hexagonal rod:
When hexagonal rod processed by needs time, stretching in hexagon holding chamber 5 by its one end from the corresponding good angle of circular cone 2, tapered cup nut 4 turns clockwise clamping hexagonal rod.Again this stationary fixture axis body 1 being fixed on the three of lathe and grab on chuck, hexagonal rod just can be processed by lathe.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
