Abstract
The invention provides a device for coaxially detecting the coaxial errors of inner holes and outer circles, in particular to a device which has high detection efficiency and can accurately and rapidly detect the coaxiality of the inner holes and the outer circles of workpieces. In the invention, the lower side of the axial direction of a movement rest is provided with an elongated slot; a ladder-shaped lever (6) the lower base of which extends toward both sides is movably connected in the elongated slot; a cylindrical pin (7) connected on a ladder-shaped boss of the lever (6) is the rotating fulcrum of the lever (6) and forms a mechanical lever dial indicator together with a dial indicator connected on the rear ladder-shaped sunken extension end of the lever (6); a locating shaft pin (1) sleeved with the detection workpieces is also fixedly connected above a sunken slotted hole of the front end of the lever (6). The detection tool has simple structure, convenient operation and strong practicability, can be widely applied to detecting similar workpieces and can be standardized and universalized.
Description
Technical field
The invention relates to the pick-up unit of measuring endoporus and outer circles error.
Background technology
Detect the measuring method of drill bushing, lining endoporus and outer circles in the prior art, be to utilize machine tool three-jaw chuck to clamp an end of drill bushing, after looking for interior hole circle with clock gauge earlier, the clock gauge gauge outfit is placed on drill bushing, lining cylindrical place, the rotation machine tool chief axis, with the maximum difference of clock gauge indicating value as the tested part coaxiality error.Another kind method adopts unit clamp alignment holes axis and clamps part, goes up the three-dimensional machines again and detects.Above-mentioned detection method needs the workman constantly to adjust the position of detection when detecting, and efficient is low, and the correctness of detection and accuracy be cannot say for sure to demonstrate,prove.
Summary of the invention
The objective of the invention is to, propose a kind of detection efficiency height, can detect the axiality detection device of workpiece endoporus and cylindrical quickly and accurately.
The technical solution adopted for the present invention to solve the technical problems is: the device of a kind of coaxial detection endoporus and outer circles error, comprise, a clock gauge that has dial framework, it is characterized in that, axial downside at dial framework has elongated slot, be connected with the trapezoidal lever of going to the bottom and extending in the elongated slot to both sides, the straight pin that connects on this lever trapezoid boss is the rotating fulcrum of described lever, and the clock gauge on being vertically connected on the sagging extended end in the trapezoidal back of lever is formed the mechanical type lever clock gauge; Above the slotted eye that this lever front end sink, also be fixedly connected with the location axle pin that a suit detects workpiece.
The present invention has following beneficial effect than prior art.
This testing tool utilizes the lever principle of mechanical type lever clock gauge, introduce and measure the drill bushing location axle pin, but the right alignment of fast detecting drill bushing, lining endoporus and cylindrical improves detection efficiency.This testing tool is simple in structure, and is easy to operate, and manufacturing expense is low, practical, with short production cycle, can be widely used in the detection of similar part, can standardization, universalization.
Description of drawings
Fig. 1 is the organigram of the device of coaxial detection endoporus of the present invention and outer circles error.
Among the figure: 1 location axle pin, 2 dial frameworks, 3 clock gauges, 4 holding screws, 5 survey pin, 6 levers, 7-straight pin, 8 gauge heads.
Embodiment
In Fig. 1, be used for the device of coaxial detection endoporus and outer circles error, comprise a clock gauge 3 that has dial framework 2.Dial framework 2 is special hole end face agent structures to axially bored line verticality cubing.Axial downside at dial framework 2 has the elongated slot that extends to big end, rear portion vertically, is connected with the trapezoidal lever 6 of going to the bottom and extending to both sides in the elongated slot.Lever 6 is connected firmly on above-mentioned elongated slot one sidewall by straight pin 7.The straight pin 7 that connects on lever 6 trapezoid boss is rotating fulcrums of this lever 6.The gauge outfit of clock gauge is by the axial vertical aperture of vertical dial framework on the big end step of above-mentioned dial framework 22, is vertically connected on above-mentioned trapezoidal lever 6 by the survey pin 5 of surveying the pin termination and sink on the ends that prolong, and forms the mechanical type lever clock gauge together.On going to the bottom this lever 6 that forward end extends, trapezoidal lever 6 also is shaped on gauge head 8.Detect the slotted eye of the location axle pin 1 of workpiece,, connect firmly on the upper wall plane of dial framework above the elongated slot by preventing that location axle pin 1 from rotating trip bolt 2/4 in dial framework 2 by the trapezoidal sagging formation of elongated slot front end.During detection, workpiece is sleeved on the location axle pin 1.On the dial framework above the baseplane on the above-mentioned trapezoidal lever 6, be provided with the dormant screw 1/4 of an adjustment (adjusting) lever.Clock gauge 3 one ends are placed in the upper end hole of dial framework 2 big end steps.End face at big end step is provided with the holding screw 4 that prevents that clock gauge from rotating in dial framework.
In testing process, tested part is located with the testing tool location axle pin, and location axle pin is rotated in the tested part hole.During detection, tested part is put into location axle pin 1, with clock gauge zeroing, and the contact screw of adjustment and lever 6 front ends, gauge head 8 contact with the tested part outer rim, survey and sell 5 and contact, rotation dial framework 2 or tested part turned round 180 ° with the contact of clock gauge.Utilize gauge head 8 on the lever front end and the survey pin 5 on lever 6 ends, transmit the contact point with the clock gauge contact, clock gauge is in the indicating value of a plurality of positions of tested part outer rim.Write down the maximum difference of the indicating value of clock gauge, the maximum difference of indicating value is exactly the tested part coaxiality error.This its value is directly read by the clock gauge instrument, directly measures measured parameter, is called direct measuring method.
Above-described only is the preferred embodiments of the present invention.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, can also make some distortion and improvement, such as, the arch that has certain radian or arc can also be adopted such as described trapezoidal lever.These changes and change should be considered as belonging to protection scope of the present invention.
