Description
Technical field
The present invention relates to measurement mechanism field, particularly relating to a kind of take pin-and-hole as the device of reference measurement internal end surface of pin seat jitter parameter.
Background technology
The inner face of key seat there will be end face out-of-flatness, inner face place plane and key seat bottom surface off plumb problem and does not reach the requirement of certified products.Measurement means of the prior art is, get a sizeable chock and insert from key seat upper open end, have a hole in the middle of chock, the diameter in hole is identical with the pin-and-hole diameter of key seat, and vertical with the plug face in chock; One is looked for have the plunger in 0.02 gap with pin-and-hole; Pin-and-hole and chock interstitial hole can be certified products by plunger smoothly, otherwise are unacceptable product.Whether prior art can test out internal end surface of pin seat place plane vertical with key seat bottom surface, and inspection whether do not measure internal end surface of pin seat smooth; And need to find the suitable chock of size and plunger, intricate operation is time-consuming, makes troubles to staff.If want to improve production technology, technician must obtain the design parameter of beating of internal end surface of pin seat and key seat pin-and-hole, and this point is also that prior art cannot be accomplished.
Summary of the invention
The object of this invention is to provide a kind of take pin-and-hole as the device of reference measurement internal end surface of pin seat jitter parameter.
For solving the problems of the technologies described above, the present invention adopts following scheme:
Internal end surface of pin seat measurement mechanism, comprise cylindrical measurement main body, the cross section measuring body interior axis place is provided with the upper and lower measuring staff be parallel to each other, the left end of upper and lower measuring staff is connected to a gauge head, the two measuring staff other ends are connected with one handle respectively close to end, and two measuring staff ends are connected with data receiver display device respectively.
During measurement, measure main body and insert key seat hole, pass through control handle, realize the movement of the probe on measuring staff, after making probe be adjacent to the inner face of the key seat that will measure, circumference 360 ° of wheel measuring main bodys, realize the circumference of popping one's head in along 360 °, inner face surface and move, the data measured by probe reach data receiver display device and show.
Described internal end surface of pin seat measurement mechanism, its data receiver display device is meter or electronic sensor receiving trap.Meter can be rough display jitter parameter, if go for more accurate parameter, electronic sensor receiving trap can reach this requirement better.No matter be any device, all reach the object measuring jitter parameter, breach the technology barrier of prior art, for contribution has been made in commercial production and technological improvement.
Described internal end surface of pin seat measurement mechanism, on upper measuring staff, cover has the first spring, and the first spring is in compressive state.
Described internal end surface of pin seat 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 make the gauge head of duty be adjacent to inner face, and make the principle of work of measurement mechanism more reasonable, the data measured are more accurate.
Described internal end surface of pin seat 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, locator data receiving and displaying device, determines the position of data receiver display device, also prevent the error brought to measurement data because of itself weight simultaneously.
Described internal end surface of pin seat measurement mechanism, the position measuring the corresponding gauge head of body surfaces has groove.When measurement mechanism not in working order or to key seat pin-and-hole insert process in, gauge head can along with the handle connecting measuring staff, rotate around the bus position at measuring staff place, gauge head is hidden in and measures in the groove of the corresponding probe location of body surfaces, the wearing and tearing avoiding gauge head to cause because of unexpected collision and breaking-up.
Compared with prior art, tool has the following advantages in the present invention:
Whether the present invention is when detecting internal end surface of pin seat and being qualified, eliminate the step of the chock selecting suitable dimension, decrease workload, and the jitter parameter of internal end surface of pin seat can be measured, breach the technology barrier cannot measuring jitter parameter in prior art, for commercial production and technological improvement are made contributions.
