Description
Technical field
The present invention relates to the honing head air measuring device of a kind of measurement mechanism, particularly a kind of extension type.
Background technology
The radial feed of dual-feed honing head oilstone relies on moving axially of tapered sleeve, cone to make the conical surface act on to promote it on the oil stone base oblique angle face and radially swells, and realizes rough honing feeding and microhoning feeding respectively.And adopt contactless pneumatic gauging, and make the honing head work in-process realize measuring automatically, avoided contact measuring head to the scuffing of workpiece and the wearing and tearing of gauge head, reduced the influence to certainty of measurement such as machine vibration, thermal deformation simultaneously again.Therefore, can realize the dual-feed honing head of measurement automatically, represent the advanced level of honing head technology.
In the honing process, carrying out at present pneumatic gauging generally is to be employed in fixing pneumatic gauging nozzle and guiding baffle are set on the honing head; Pneumatic measuring instrument through linking to each other with the pneumatic gauging nozzle carries out non-contact measurement to honing bores; This metering system has higher certainty of measurement; Be generally about 0.004-0.008mm; But require gap between pneumatic gauging nozzle and the workpiece less than 0.1 ㎜ in the above-mentioned measuring process, introduce workpiece or in honing processing with measure in the process of accomplishing back honing stone withdrawal at honing head like this, gaging nozzle and guiding baffle are easily with manufactured bore area scuffing workpiece.How to address the above problem, become one of moving difficult point of measuring use of restriction.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists; Provide a kind of at honing head introducing workpiece or after honing processing and measuring completion; Pneumatic gauging nozzle and guiding baffle regracting scratch the honing head air measuring device of the extension type of manufactured bore area to avoid pneumatic gauging nozzle and guiding baffle.
For realizing the foregoing invention purpose; Technical scheme of the present invention is: a kind of honing head air measuring device of extension type; Comprise the guiding baffle and the pneumatic gaging nozzle that are installed on the honing head; It is characterized in that pneumatic gauging nozzle and guiding baffle interfix, on honing head, be provided with the mobile device that can move radially along honing head with guiding baffle opposite position, mobile device links to each other with the guiding baffle.
Above-mentioned mobile device is made up of hole of on honing head, opening and the piston that is installed in the hole; The piston rod of piston one end links to each other with the guiding baffle; The stage clip that can make piston reset is installed on piston rod, in honing head, have with above-mentioned honing head on the pipeline that moves of the promotion piston that is connected of the hole of opening.
The exit end face of above-mentioned pneumatic gauging nozzle is lower than the face relative with the workpiece to be machined endoporus on the guiding baffle.
The inlet end of above-mentioned pneumatic gauging nozzle links to each other with pneumatic gauging passage in the honing head through flexible pipe.
Adopt removable being tightly connected between the periphery of above-mentioned pneumatic gauging nozzle and the honing head.
The present invention makes fixing pneumatic gaging nozzle on the present honing head and guiding baffle into packaged type; So just can effectively avoid honing head introduce workpiece or in honing processing and measure accomplish after; Honing stone withdrawal and honing head withdraw from the process of workpiece, and gaging nozzle the problem that manufactured bore area scratches occurs with the guiding baffle.Because the structure of honing head is very complicated; The present technique scheme utilizes honing head body as cylinder body; Piston is installed in cylinder body, is utilized moving of piston, drive gaging nozzle and guiding baffle are introduced workpiece or withdrawal after honing processing and measurement completion at honing head; When measuring, radially outward reach the measuring position, and existing hydraulic pressure or baric systerm on the power that piston the moves honing head capable of using.Characteristics such as that this device has is rational in infrastructure, novel, practicality is good can effectively solve the problem that air measuring device on the existing honing head scratches manufactured bore area easily.
