Embodiment
Referring to accompanying drawing 1.
A kind of device for testing compression height of cylinder body is made up of detection components and positioning component;
Described detection components is by the detection positioning plate 13 that center pit is arranged, with the detection mandrel 6 of the center pit pivot bush unit of detection positioning plate 13, the indicator bracket 12 fixedlyed connected with detection positioning plate 13 in two ends, be connected the dial gauge 10 on the indicator bracket 12 and the spacer pin 2 that is connected on the indicator bracket 12 by clamping screw 1 constitutes by lock-screw 11;
Described positioning component is made of positioning core axle 14, the positioning core axle handle 9 of fixedlying connected with positioning core axle 14 1 ends;
Described positioning core axle handle 9 is threaded with positioning core axle 14 1 end center fixation, and connection of thread be provided with plain washer 8 with spring washer 7, make be connected more firm;
Also have on the binder bolt 1 of described binding indicator bracket 12 and detection positioning plate 13 spring washer 4 with plain washer 5, make be connected more firm.
During use, " detection components " in this device for testing compression height of cylinder body part vertically is provided with, as shown in Figure 1, follows these steps to manipulate:
1, setting theoretical inspection mandrel axial location and " detection components ", self to carry out the distance setting of " corrections ", " to 0 " position (that is: detection mandrel 6, detection positioning plate 13 are close to position) be fixed value H;
2, according to the relevant physical size after detection mandrel 6, detection positioning plate 13, the positioning core axle 14 processing completions, the H value of setting is revised.The revision value is H '.H ' is " calibration value " that detects.
3, in the process that detects, should carry out following step:
A. at first " detection components " carried out self " correction ", (that is: detection mandrel 6, detection positioning plate 13 are fitted good position with the dial gauge 10 " to 0 " that detects);
B. with the cylinder block horizontal positioned, positioning core axle 14 with positioning component (spring washer 7, plain washer 8, positioning core axle handle 9, positioning core axle 14) is put in (cylinder block front end or rear end) in the crankshaft hole again, then detection components (clamping screw 1, spacer pin 2, binder bolt 3, spring washer 4, plain washer 5, detection mandrel 6, dial gauge 10, lock-screw 11, indicator bracket 12, detection positioning plate 13) is put on the positioning core axle 14 by casing bore by shown in Figure 1, and makes the locating surface of detection positioning plate 13 and the last plane of cylinder block fit good;
C. actual read number and the H ' with dial gauge 10 compares, and its deviate is K: pointer is that pointer is a negative value (-) at H ' left side K on the occasion of (+) at H ' right side K.The indicating accuracy of dial gauge 10 is the accuracy of detection of testing result;
If d. the theoretical value of compression height is A, the actual compression height is A '.Then:
A′＝A-K
Result according to above-mentioned steps detects compares with the product drawing designing requirement, then illustrate that as dimensional discrepancy product processing meets the requirements in the designing requirement scope, otherwise the explanation product is defective.That this device is manipulated is very convenient, labour intensity is low, can be accurately in the cylinder block process, easily compression height is detected and controls.
