Description
Technical field
The present invention relates to a kind of pick-up unit, especially a kind of sphere distance that is used for gear detects frock.
Background technology
The detection method of involute cylindrical gear transverse tooth thickness is varied, and wherein Chang Yong method has common normal detection method and sphere distance detection method (spur gear also can use and stride rod apart from method).Usually, external tooth generally uses the public law collimation method, promptly detects common normal with common normal micrometer.Sometimes, because the needs of design, same external tooth also can only use the sphere distance method to come indirect detection transverse tooth thickness.Generally speaking, adopt cylindrical rod (at spur gear) or ball (at spiral gear) to use cementing agent (such as grease etc.) or adopt the magnetic force method to stick in the teeth groove for the little gear of modulus (modulus is generally less than 5), use corresponding milscale to detect then to stride rod apart from or sphere distance; For the big gear of modulus, because the weight ratio of cylindrical rod or ball is bigger, and be far longer than the load that cementing agent or magnetic force can bear, generally detect by double or many people, one people or many people hand rest cylindrical rod or ball, other personnel then use milscale to detect.All there is very big shortcoming in these methods, such as using binder method, under the very high situation of room temperature, such as summer, the viscosity of grease class reduces greatly, even has become the scattered paste shape thing, cylindrical rod or ball securely can't bond, cylindrical rod or cylinder ball are easy to be shed to other places, even fall into lathe, bring very big potential safety hazard to equipment such as lathes; If use the magnetic force method, cause gear to produce very big remanent magnetism phenomenon easily, in following process, adsorb metal dirts such as iron filings easily, the quality of gear is brought very big hidden danger; If adopt many people detection, must improve these people's mutual harmony, detection efficiency is very low in actual production, is not suitable for producing in enormous quantities.
At present, on the market existing direct detection stride rod apart from or the special detector of sphere distance have following general character shortcoming: the one, must be put into gear to be detected on the monitor station of detector and detect, this detects to product and brings very big inconvenience, particularly heavy for texture ratio, bulky product, these gears sustain damage when carrying and/or detection easily, once the rod (ball) of striding of these gears does not meet design or technological requirement after detecting with those special detectors, so because process redundancy is very little, this gear is difficult to produce again, cause scrapping, bring unnecessary cost waste to production; The 2nd, every kind of range of detector own is confined to a certain section sensing range, just needs in the actual production like this to be equipped with a large amount of special measuring tools, cause economically with the place on waste; The 3rd, the part special detector can't or very difficult gauging calibration, cause measuring cost very high.
Summary of the invention
The object of the present invention is to provide the big and sphere distance that be convenient to gauging calibration of a kind of simple in structure, easy to operate, sensing range to detect frock.
In order to achieve the above object, technical scheme of the present invention is: a kind of sphere distance detects frock, comprise milscale, the ball of two Connection Blocks and two same diameter, wherein Connection Block has the endoporus of connection and ball placed cavity, the Connection Block both sides all have the breach of putting into the ball placed cavity and connecting with the ball placed cavity for ball, the body of wall of the ball placed cavity on the Connection Block then is two carriages, the equal arc groove of the inwall of two carriages, the connection endoporus of two Connection Blocks is sleeved on to loose fit respectively on the sounding rod at two ends of milscale, also have on the Connection Block and be connected the threaded hole that endoporus communicates, holding screw is screwed into threaded hole and its end and sounding rod and offsets, the place, outer end of two carriages on the Connection Block all has the anti-lost step of ball, two balls are placed on respectively in the ball placed cavity of two Connection Blocks, during detection, ball contacts with the measurement face of the sounding rod of milscale.
Threaded hole on the described Connection Block has two or more, and a holding screw all is housed on each threaded hole.
The difference of the diameter between the connection endoporus of described Connection Block and the sounding rod of milscale is not more than the diameter of 0.02 * sounding rod.
The diameter of described ball is 1.6～1.9 * module to be detected, the radial dimension of ball placed cavity is greater than the diameter of ball, the difference of both diameters is not more than 0.01 * module to be detected, ball placed cavity length can guarantee can axially move freely along the ball placed cavity after ball is put into, and this moves freely the diameter that distance is not more than 0.2 * ball.
The radial dimension of the anti-lost step of described ball is less than the diameter of ball, and the difference of both diameters is no more than 0.006 * module to be detected.
Two end faces of each carriage of described Connection Block are parallel to each other and are symmetrical vertically, and the breach axial length is placed the length of inner chamber and the width sum of the anti-lost step of ball greater than ball.
Described ball placed cavity be connected endoporus and keep almost coaxial.
After adopting said structure, have the following advantages: simple in structure, low cost of manufacture, ratio of precision is higher; Suitable range ability is wider, and sensing range is big; Need not to work out special metrological regulation and the special gauging instrument of buying,, be convenient to gauging calibration, reduced manufacturing cost, practicality and high efficiency as long as demarcate milscale and ball by normal flow process.
