Abstract
The invention relates to the field of measuring devices and in particular relates to a device for measuring a run-out parameter of an internal end surface of a pin boss on the basis of a pin hole; the device comprises a cylindrical measuring main body, wherein an upper measuring bar and a lower measuring bar parallel to each other are arranged on the section in which the internal axis of the measuring main body is disposed; the left ends of the upper measuring bar and the lower measuring bar are respectively connected with a measuring head; a handle is respectively connected with the positions on the other ends of the two measuring bars and close to the tail ends; and the tail ends of the two measuring bars are respectively connected with a data receiving and displaying device. When the internal end surface of the pin seat is detected to be qualified or not by the device, the step of selecting a block with proper size is avoided, the work load is reduced, in addition, the run-out parameter of the internal end surface of the pin seat can be measured out, the technical obstacle that the run-out parameter can not be measured in the prior art is broken out, and a contribution is made to industrial production and technologies.
Description
Technical field
The present invention relates to the measurement mechanism field, relate in particular to a kind of take the device of pin-and-hole as reference measurement key seat inner face jitter parameter.
Background technology
The requirement that do not reach certified products end face out-of-flatness, plane, inner face place and key seat bottom surface off plumb problem can appear and in the inner face of key seat.Measurement means of the prior art is, gets a sizeable chock and inserts from the key seat upper open end, in the middle of the chock hole arranged, and the diameter in hole is identical with the pin-and-hole diameter of key seat, and vertical with plug face in the chock; Look for one and pin-and-hole that the plunger in 0.02 gap is arranged; Pin-and-hole and chock interstitial hole can be certified products by plunger smoothly, otherwise are unacceptable product.Whether prior art can be test out plane, key seat inner face place vertical with the key seat bottom surface, and inspection whether do not measure the key seat inner face smooth; And need to seek suitable chock and the plunger of size, it is loaded down with trivial details time-consuming to work, and makes troubles to the staff.If want production technology is improved, the technician must obtain the design parameter of beating of key seat inner face and key seat pin-and-hole, and this point also is that prior art can't be accomplished.
Summary of the invention
The purpose of this invention is to provide a kind of take the device of pin-and-hole as reference measurement key seat inner face jitter parameter.
For solving the problems of the technologies described above, the present invention adopts following scheme:
Key seat inner face measurement mechanism, comprise the cylindrical measurement main body, the cross section of measuring body interior axis place is provided with the upper and lower measuring staff that is parallel to each other, the left end of upper and lower measuring staff is connected with respectively a gauge head, the two measuring staff other ends are connected with respectively one handle near end, and two measuring staff ends are connected with respectively the data receiver display device.
During measurement, measure main body and insert the key seat hole, pass through control handle, realize the movement of the probe on the measuring staff, after making probe be adjacent to the inner face of the key seat that will measure, circumferential 360 ° of wheel measuring main bodys realize probe along the circumferential movement on 360 ° on inner face surface, and the measured data of popping one's head in reach the data receiver display device and show.
Described key seat inner face measurement mechanism, its data receiver display device are meter or electronic sensor receiving trap.Meter can be rough the demonstration jitter parameter, if go for more accurate parameter, the electronic sensor receiving trap can reach this requirement better.No matter be any device, all reached the purpose of measuring jitter parameter, broken through the technology barrier of prior art, for contribution has been made in commercial production and technological improvement.
Described key seat inner face measurement mechanism, cover has the first spring on the upper measuring staff, and the first spring is in compressive state.
Described key seat inner face measurement mechanism, lower measuring staff is connected with the end of gauge head one end, is connected with the second spring, and the second spring is in compressive state.First, second spring of compression can be so that the gauge head of duty be adjacent to inner face, so that the principle of work of measurement mechanism is more reasonable, the data of measuring are more accurate.
Described key seat inner face measurement mechanism is characterized in that, measures main body one end and is provided with data receiver display device bracing frame.Bracing frame is used for supporting, the locator data receiving and displaying device, has determined the position of data receiver display device, has also prevented the error of bringing to measurement data because of itself weight simultaneously.
Described key seat inner face measurement mechanism, the position of measuring the corresponding gauge head of body surfaces has groove.When measurement mechanism not in working order or in the process of inserting to the key seat pin-and-hole, gauge head can be along with the handle that connects measuring staff, rotate bus position around the measuring staff place, so that gauge head is hidden in the groove of measuring the corresponding probe location of body surfaces wearing and tearing and the breaking-up of avoiding gauge head to cause because of unexpected collision.
The present invention compared with prior art has following advantage:
Whether qualified the present invention detecting the key seat inner face when, omitted the step of the chock of selecting suitable dimension, reduced workload, and can measure the jitter parameter of key seat inner face, broken through the technology barrier that to measure jitter parameter in the prior art, for commercial production and technological improvement are made contributions.
