Description

A kind of high precision sphere diameter cubing
Technical field
The present invention relates to a kind of ram pump cubing, a kind of high precision sphere diameter cubing, belongs to cubing equipment technical field specifically.
Background technology
In the production run of inclined shaft pump, often be unable to do without the processing of main shaft ball-and-socket, and ball-and-socket processing being the part that inclined shaft pump difficulty of processing is the highest, requirement is the harshest, is also directly affect the serviceability quality of inclined shaft pump, the key component of life-span length.
There are two kinds of methods detecting ball-and-socket diameter present stage: one, colouring; Two, three-dimensional inspection;
1, the measurement of interior ball-and-socket diameter dimension in the processing of production scene is always a great problem, and traditional method is manufacture one group of sphere, and painted gauge, checks by painted method.Whether the rear actual diameter size qualification of interior ball-and-socket processing is judged according to the size of the actual stained area of workpiece ball-and-socket.The measuring accuracy of colouring is often relevant with the manufacturing accuracy of the painted gauge of measuring sphere, also relevant with the factor such as thickness and granules of pigments size of smooth operation, dyed layer.General provision granules of pigments is not more than 0.5um, and painted thickness is no more than 3um.Although therefore this inspection method is relatively more directly perceived, technical difficulty is high, often not easily grasps again in practical operation, so measuring error is larger, the result recorded is again a scope, cannot measure actual value, brings difficulty to the manufacture of the high spheric motion pair of precision.
2, three-dimensional detects.Although three-dimensional detects, precision is high, and its detection time is long, and when producing, every part part all adopts three-dimensional coordinates measurement be and lose time also to be unallowed.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of easy to use, high precision sphere diameter cubing that degree of accuracy is high, easy and simple to handle is provided.
According to technical scheme provided by the invention, a kind of high precision sphere diameter cubing comprises sounding rod, cubing body, measures axle, spring, clock gauge and measuring head, it is characterized in that: measure axle top and be connected in cubing body, the upper end of sounding rod is positioned at measures axle, the middle part of sounding rod is slidably connected in cubing body, and the lower end of sounding rod is stretched out cubing body and is threaded connection measuring head; The measuring junction of clock gauge stretches into the interior also contact measurement bar of cubing body, pocketed springs on the measuring junction of clock gauge, spring upper end contact cubing body madial wall, lower spring end contact measurement bar.
Further, be provided with packing ring between cubing body and clock gauge, cubing body sidewall connects lock-screw, can by cubing body, clock gauge and washer locking by lock-screw.
Further, sounding rod is T-shaped.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, convenient, fast to spherical diameter measurement, accurate, easy to carry, can use whenever and wherever possible, substantially increases rate easy to detect.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Description of reference numerals: 1-sounding rod, 2-cubing body, 3-measure axle, 4-spring, 5-packing ring, 6-clock gauge, 7-lock-screw, 8-measuring head, 9-ball-and-socket.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises sounding rod 1, cubing body 2, measures axle 3, spring 4, clock gauge 6 and measuring head 8.
Measuring axle 3 top is connected in cubing body 2, and the upper end of T-shaped sounding rod 1 is positioned at measures axle 3, and the middle part of sounding rod 1 is slidably connected in cubing body 2, and the lower end of sounding rod 1 is stretched out cubing body 2 and is threaded connection measuring head 8.
The measuring junction of clock gauge 6 stretches into the interior also contact measurement bar 1 of cubing body 2, pocketed springs 4 on the measuring junction of clock gauge 6, spring 4 upper-end contact cubing body 2 madial wall, spring 4 lower end contact measurement bar 1.
Be provided with packing ring 5 between described cubing body 2 and clock gauge 6, cubing body 2 sidewall connects lock-screw 7, cubing body 2, clock gauge 6 and packing ring 5 can be locked by lock-screw 7.
Principle of work of the present invention is: when using this cubing, first carries out examination to the ball-and-socket of part and grinds, repeatedly send three-dimensional coordinates measurement until grinding size and required size close, part now, we are referred to as master body.
Before use sphere diameter cubing detects part sphere diameter, need first by clock gauge school zero (being convenient to gauger's reading).Concrete operations are as follows: operator holds cubing body 2, toward pressing down, measurement axle 3 top is contacted with ball-and-socket 9 sphere diameter cubing, now measuring head 8 contacts with bottom ball-and-socket 9, measuring head 8 should be stressed, sounding rod 1 moves upward, the spring 4 being now originally in free state will be compressed, on clock gauge 6, numerical value will change simultaneously, at this moment the read text scale dish of clock gauge 6 is rotated, make the pointed zero point of now clock gauge 6, then allen key is used, screw lock-screw 7, now packing ring 5 is tightened up because of the power of being squeezed, and then the height and position of clock gauge 6 is determined, after completing above operation, namely school zero completes.
After completing school zero, operator can measure the size of ball-and-socket 9 sphere diameter fast when processing ball-and-socket 9 part
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
