As shown in Figures 1 to 6; the concrete structure of this tappet bottom surface difference in height cubing comprises: cubing body 1 and the dial framework slide block 2 being slidably matched with cubing body 1; and be laid in the dial gauge 3 on dial framework slide block 2; wherein; cubing body 1 is with direction recess, for locating and adjust the pilot hole of tested tappet height and position and the gauge outfit protector (groove depth 0.4mm) of a longitudinal the foot section brought transition arc and for convenient two holes of stepping down of taking out tested tappet, being also provided with in addition for adjusting kicker and head part spring and the tappet lock-screw of tested tappet height.Dial framework slide block 2, with adaptive two directed side of sliding of the direction recess with cubing body 1, can guarantee that gauge head is measured the path contacting at every turn identical, and measurement data is reproducible.In cubing body, design for locating and adjust the pilot hole of tested tappet, can guarantee that gauge head axis plane and tested tappet axle central plane are coplanar, guarantee the requirement of measuring condition coincidence pattern, measurement result is more accurate, measurement efficiency is high, while having avoided using with contourgraph and the measurement of three coordinate machines, Measuring Time is long, and efficiency is low, and the higher defect of measurement expense.
As shown in Figure 7 to 10, the end face of cubing body 1 offers direction recess 11 and tappet pilot hole 12, and direction recess 11 is the rectangular channel of laterally laying.Tappet pilot hole 12 is for location and adjust tested tappet height and position, enough little with the tolerance clearance of tappet circle product external cylinder, the measuring error causing to reduce tolerance clearance; Its upper port is positioned at direction recess baseplane, and port both sides offer the hole 15 of stepping down relatively, the tested tappet of convenient taking-up; Axis is perpendicular to direction recess baseplane, the measuring error causing to reduce pilot hole axis verticality error; Direction recess baseplane offers gauge outfit protector 13, and gauge outfit protector 13 is moved towards to extend along direction recess, longitudinal head and tappet pilot hole 12 interfaces, and longitudinally afterbody has transition arc (groove depth is preferably 0.4mm).The both sides of cubing body 1 offer the lock-screw hole of laterally running through tappet pilot hole 12 relatively, by tappet lock-screw 14, lock from the side the tested tappet being laid in tappet pilot hole 12.The lower port of tappet pilot hole 12 is laid with tappet head part assembly, for from the tested tappet of bottom elasticity jacking, is convenient to the tested tappet product measurement of different longitudinal lengths.Tappet head part assembly comprises: directly support the kicker 16 of tested tappet and the cover plate 17 sealing for bottom, and be laid in the spring 18 between kicker 16 and cover plate 17, and cover plate 17 is by hexagon socket cap head screw 19(M3X8) be fixed on cubing body 1 bottom surface.
As shown in Figure 11 to 14, two directed side 21 that the bottom of dial framework slide block 2 has percentage gauge outfit measuring flume and slides with direction recess 11 adaptations of cubing body 1, the lateral face tolerance clearance of direction recess 11 and two directed side is enough little, the measuring error causing to reduce lateral face tolerance clearance.The vertical direction of dial framework slide block 2 offers dial gauge mounting hole 22, and dial gauge 3 is vertically inserted in dial gauge mounting hole 22 by lining 31, and its gauge outfit stretches into percentage gauge outfit measuring flume.The both sides of dial framework slide block 2 offer the dial gauge lock-screw nail that laterally runs through dial gauge mounting hole 22 relatively, by dial gauge lock-screw 32, lock from the side the dial gauge 3 being laid in dial gauge mounting hole 22.Two of the bottoms directed side 21 of passing through of dial framework slide block 2 coordinates installation with the direction recess 11 of cubing body 1, make gauge head (gauge outfit) axis plane and the tested tappet axle central plane of dial gauge 3 coplanar, guarantee the requirement of measuring condition coincidence pattern, measurement result is more accurate, measures efficiency high.
The concrete steps of measuring are as follows:
1) cubing is placed on platform, and with clean each working surface of cotton wiped clean cubing.
2) unscrew tappet lock-screw 14, and tested tappet is put into the tappet pilot hole 12 of cubing body.
3) adjust longitudinal height of tested tappet; guarantee that sphere edge, tappet bottom is lower than direction recess 11 baseplanes; guarantee again that sphere edge, tappet bottom is higher than gauge outfit protector 13 surfaces of longitudinal the foot section brought transition arc on cubing body simultaneously; then with tappet lock-screw 14, tested tappet is locked to (so tested tappet height can guarantee that dial gauge gauge outfit can enter into low Surface Contact in slipping from high Surface Contact, reaches the object of protection dial gauge gauge outfit).
4) the dial framework slide block 2 that dial gauge 3 is housed is put into the direction recess 11 (without one end of gauge outfit protector) of cubing body 1, and by dial gauge scale zero setting position.
5), with the tight dial framework slide block 2 of hand, the direction recess 11 along on cubing body 1, makes dial framework slide block slowly slip over certain distance together with dial gauge, just can be by tested tappet bottom level difference measurements out by difference between the reading flex point of dial gauge.
6) continue dial framework slide block 2 slowly to be slided into the extreme position of one end of gauge outfit protector along the direction recess 11 on cubing body 1, now dial gauge 3 pointers should point to scale zero-bit, otherwise require to re-start measurement.
7) measure the preservation that each working surface of cubing will be oiled after finishing.Concrete operating process refers to Fig. 6.
To sum up, this tappet bottom surface difference in height cubing is simple and reasonable, by design, match the cubing body with direction recess that uses and with the dial framework slide block of two directed side, can guarantee that gauge head is measured the path contacting at every turn identical, solved the difficult problem of setting up of measuring condition, measurement data is reproducible, and dispute is few.In addition, in cubing body, design for locating and adjust the pilot hole of tested tappet, can guarantee that gauge head axis plane and tested tappet axle central plane are coplanar, guarantee the requirement of measuring condition coincidence pattern, measurement result is more accurate, measures efficiency high, while having avoided using with contourgraph and the measurement of three coordinate machines, Measuring Time is long, efficiency is low, and the higher defect of measurement expense, is applicable to using on production line.
Disclosed is above only several specific embodiment of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
