A pneumatic measuring head is a cylinder and is internally provided with eight small nozzles and two large nozzles; the eight small nozzles are connected with a pipe pneumatic measuring instrument via an air inlet joint for realizing measurement of average diameter; and the two large nozzles are connected with another pipe pneumatic measuring instrument via air inlet joints for realizing measurement of roundness. The thin-wall cylinder liner internal diameter measuring instrument is matched with the pneumatic measuring instruments for quickly measuring the average diameter of any section of the internal diameter, roundness measurement can be realized when a workpiece is rotated for one circle, taper measurement can be realized when the workpiece is moved vertically, the measuring head is not directly contacted with the measured surface, influences of the measuring force on the measuring result are reduced, wear of the measuring head is little due to non-contact measurement, and the service life is long.
Description
Technical field
The utility model belongs to precision measuring instrument, is specifically related to a kind of simple in structure, easy to operate, degree of accuracy is high, measuring speed is fast thin-wall cylinder casing internal diameter measuring instrument.
Background technology
In China's cylinder sleeve industry production, the measurement of cylinder sleeve internal diameter is generally all used to traditional internal diameter bore gauge, this method is feasible to wet cylinder liner, still not exclusively applicable to thin-walled dry cylinder liner, especially cylinder diameter is at Φ more than 100 and the dry cylinder liner of the about 2mm of wall thickness, very poor because of its radial rigidity, although only a little newton of internal diameter bore gauge gaging pressure, cylinder sleeve still produces elastic deformation, measurement deflection approximately 10-40 μ m of different parts not etc., almost cannot interpretation.
Summary of the invention
The utility model object is the deficiency that overcomes traditional mechanical measurement, conventional gauges, and a kind of easy to operate, degree of accuracy is high, measuring speed is fast thin-wall cylinder casing internal diameter measuring instrument is provided, and solves the variety of issue that existing measuring technique exists.
For achieving the above object, the technical solution adopted in the utility model is: thin-wall cylinder casing internal diameter measuring instrument is made up of Pneumatic measuring head, giant, small nozzle, worktable, lower margin, inlet suction port, school team's ring gauge.
Described Pneumatic measuring head is right cylinder, and 8 small nozzle holes are offered in right cylinder side, is 45o and is uniformly distributed in Pneumatic measuring head transverse section; Separately offer 2 giant holes, be 180o and distribute, be positioned at the same transverse section of Pneumatic measuring head; Described giant and small nozzle are middle leachy right cylinder, are pressed into respectively separately in corresponding hole, Pneumatic measuring head side; Bottom at Pneumatic measuring head is provided with inlet suction port, and 8 described small nozzle rear portions are provided with the pore communicating with the inlet suction port of Pneumatic measuring head centre bottom; Hole respectively and communicate with the inlet suction port of Pneumatic measuring head bottom margin setting in 2 described giant rear portions.
Described Pneumatic measuring head is fixed on worktable, has below worktable four lower margins to support; Measuring instrument is furnished with two school team's ring gauges that are equivalent to the upper and lower deviation of tested cylinder sleeve internal diameter, realizes the calibration of internal diameter pneumatic gauging.
Preferably, described small nozzle is of a size of Φ 4.
Preferably, described giant is of a size of Φ 6.
The utility model adopts technique scheme to have following beneficial effect:
1, coordinate air-gauge can measure rapidly the mean diameter in the arbitrary cross section of internal diameter;
2, rotational workpieces can be realized the measurement of circularity for one week;
3, move up and down workpiece and can realize the measurement of tapering;
4, realize measuring head and directly do not contact with measured surface, reduce the impact of ergometry on measurement result;
5,, due to non-cpntact measurement, measuring head wearing and tearing are less, long service life.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Pneumatic measuring head schematic diagram.
Fig. 3 is school team's ring gauge schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of thin-wall cylinder casing internal diameter measuring instrument is as depicted in figs. 1 and 2 made up of Pneumatic measuring head 1, giant 2, small nozzle inlet suction port 31, giant inlet suction port 32, small nozzle 4, worktable 5, lower margin 6, school team's ring gauge 7.
As shown in Figure 2, Pneumatic measuring head 1 is right cylinder, and the small nozzle hole of 8 Φ 4 is offered in right cylinder side, is 45o and is uniformly distributed in Pneumatic measuring head 1 transverse section; Separately offer the giant hole of 2 Φ 6, be 180o and distribute, be positioned at the same transverse section of Pneumatic measuring head 1; Giant 2 and small nozzle 4 are pressed into respectively in Pneumatic measuring head 1 corresponding hole, side, coordinate closely air tight;
As shown in Figure 1, be provided with small nozzle inlet suction port 3 in the centre bottom of Pneumatic measuring head 1,8 small nozzle 4 rear portions are provided with the pore that leads to Pneumatic measuring head 1 center and be connected with small nozzle inlet suction port 3, are connected and can realize the measurement of mean diameter with a pipe air-gauge by small nozzle inlet suction port 3; 2 giant 2 rear lower portion are respectively equipped with 32, two giant inlet suction ports 32 of giant inlet suction port and are connected and can realize the measurement of circularity with another pipe air-gauge;
Pneumatic measuring head 1 is fixed on worktable 5, and worktable 5 has four lower margins 6 to support below; Be furnished with school team's ring gauge 7, realize the calibration of internal diameter pneumatic gauging.
School team's ring gauge 7 is as shown in Figure 3 two, and size is respectively tested cylinder sleeve internal diameter upper and lower limit;
The comparative measurement method that the utility model adopts, the plastics tracheae of drawing from the utility model inlet suction port when measurement is connected with the air outlet adapter in external equipment amount instrument body front, supply with pressurized air and guarantee that each coupling part is air tight, all normal from the pressurized air of nozzle ejection; With the multiplying power of the upper and lower limit school team ring gauge amount of carrying out instrument and the adjustment of zero-bit, after adjustment, can carry out surveying work; When measurement, replace lower school team ring gauge with tested thin-wall cylinder casing, rotational workpieces one week in measuring process, amount instrument buoy can directly be pointed out size and the roundness deviation of tested cylinder sleeve.
