Abstract
The utility model relates to a machinery processing technology field specifically discloses a geometric tolerances guiding mechanism, includes a trimmer and an activity piece at least, and the trimmer is made by flexible material, and the activity piece is made by the rigid material, and the one side and trimmer laminating, the activity piece of activity piece pass through bolt and part connected with the trimmer. During above -mentioned geometric tolerances guiding mechanism is applied to some parts of having relatively high expectations to the straightness that hangs down in mounting surface relative shaft hole, at first be fixed in the mounting surface of part through the bolt with trimmer and activity piece on, under the initial condition, with the same moment with each bolt locking, then the decrement of the locking force regulation trimmer through each bolt of adjustment, the straightness that hangs down who keeps away from the relative part shaft hole of a side surface of trimmer until the piece that will move about adjusts to meeting the requirements. This geometric tolerances guiding mechanism simple structure, convenient to use is having now under the not enough condition of precision of the machine to cost low as far as possible makes the geometric tolerances precision of part reach the installation requirement.
Description
Technical field
This utility model relates to Machining Technology field, is specifically related to a kind of form and position tolerance guiding mechanism.
Background technology
In Machining Technology field, especially during assembling, the highest to some part Geometrical Tolerance Principle, the step surface of such as some part or plane require at a relatively high with the perpendicularity of axis hole.This type of part can complete processing by high-precision machining center, it is possible to ensures the requirement of form and position tolerance.But in some enterprises, in the case of the machining accuracy of existing lathe is insufficient for the form and position tolerance required precision of part, it is necessary to carry out accuracy compensation and adjustment by other means.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of form and position tolerance guiding mechanism, to meet in the case of the machining accuracy of lathe is the highest, meets the Geometrical Tolerance Principle of part.
In order to solve above-mentioned technical problem, the technical scheme that this utility model provides is as follows: a kind of form and position tolerance guiding mechanism, at least includes:
One tab, this tab is fabricated from a flexible material, and tab is provided with at least 4 adjusting holes；
One activity template, this activity template is made up of rigid material, and fitting with tab in the side of activity template, activity template is provided with the shoulder hole that quantity, size and location are all corresponding with adjusting hole on tab；
Bolt, the specification of this bolt and quantity all adapt with the adjusting hole on tab and the shoulder hole on activity template.
Further, the material of described tab is rubber.
Further, described activity template is made up of the metal material of rigidity.
Further, the quantity of described adjusting hole is 4.
Form and position tolerance guiding mechanism of the present utility model, it is applied to some and mounting plane is required in higher part relative to the perpendicularity of axis hole, first pass through bolt tab and activity template to be fixed on the mounting plane of part, under original state, by identical moment, each bolt is locked, then by adjusting the decrement of the coupling mechanism force regulation tab of each bolt, until activity template is adjusted to meeting the requirements away from the perpendicularity of a side surface confronting parts axis hole of tab.This form and position tolerance guiding mechanism simple in construction, easy to use, in the case of existing machine tool accuracy deficiency, make the form and position tolerance precision of part reach installation requirement with alap cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of a kind of form and position tolerance guiding mechanism.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Fig. 1 show the structural representation of the specific embodiment of a kind of form and position tolerance guiding mechanism.In this embodiment, housing 10 is provided with axis hole 11, and a side end face of housing 10 is provided with counterbore 12, and there is higher required precision the bottom surface of this counterbore 12 relative to the perpendicularity of axis hole 11.In installation process, the form and position tolerance of the bottom surface of this counterbore 12 is embodied in the perpendicularity requirement relative to axis hole 11 of plane B.Owing to the machining accuracy of machine tool is not sufficient to ensure that the required precision of above-mentioned form and position tolerance, it is specifically designed the form and position tolerance guiding mechanism 20 of the present embodiment.
Above-mentioned form and position tolerance guiding mechanism 20 includes tab 21 and activity template 22.Wherein tab 21 is fabricated from a flexible material, preferably elastomeric material.Activity template 22 is rigid material, preferably identical with the material of housing 10.The bottom surface laminating of one side surface of above-mentioned tab 21 and counterbore 12, fits with tab 21 in opposite side surface.Wherein the bottom surface of counterbore 12 is provided with at least 4 screwed holes 13, preferably 4 screwed holes.Correspondingly, tab 21 is provided with the adjusting hole that quantity, position and specification with screwed hole 13 adapt；Activity template 22 is provided with the shoulder hole that quantity, position and specification with screwed hole 13 adapt.Sequentially pass through shoulder hole, adjusting hole and screwed hole 13 by bolt 23 to be fastenedly connected.
Under original state, by identical moment, 4 bolts are locked, then by adjusting the decrement of the coupling mechanism force regulation tab of each bolt, until activity template is adjusted to meeting the requirements away from the perpendicularity of a side surface confronting parts axis hole of tab.This form and position tolerance guiding mechanism simple in construction, easy to use, in the case of existing machine tool accuracy deficiency, make the form and position tolerance precision of part reach installation requirement with alap cost.
In a word; the foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
