Abstract
The utility model provides a center distance detecting tool for a trapezoidal sealing ring groove, which solves the technical problem that a special sample plate is adopted for detecting the center distance of a trapezoidal sealing ring groove of a high pressure compressor cylinder. While the special sample plate is not accurate, the types of the special sample plates are particularly more, and the operation and management of the special sample plates are inconvenient. The center distance detecting tool has the key points that the center distance detecting tool comprises two sets of positioning sleeves and measuring jaws; each set is installed on a jackcatch of a slide caliper; concretely, a positioning hole is arranged on the positioning sleeve; a fastening bolt is arranged on the side surface of the positioning hole so as to ensure that the measuring jaw and the jackcatch of the slide caliper are simultaneously inserted into the positioning hole of the positioning sleeve and fixed through the fastening bolts; and the interior angle of the measuring jaw is identical with the base angle of the trapezoid to be measured. The center distance detecting tool has the purpose for the detection of the center distance of the trapezoidal sealing ring groove.
Description
Technical field
The utility model relates to a kind of surveying instrument, specifically is to say the instrument of measuring keystone ring groove center distance.
Background technology
Some sealing of compressor adopts trapezoidal annular groove to add metal octangonal ring structure, obtains good sealing effectiveness.Inlet and outlet mouth as the high pressure compressor cylinder is connected sealing with subsidiary engine, generally adopt trapezoidal annular groove to add metal octangonal ring structure.This structure, its octangonal ring ring surface must have good the contact just can reach high pressure seal result with the dovetail groove side.The metal octangonal ring is the rigidity standard component, thus to the accuracy requirement of the trapezoidal closure gasket groove of cylinder than higher, must critically detect.Detecting the centre distance of trapezoidal annular groove, is the bulk that a plane and inclined-plane intersect, and uses general or etalon is difficult to reach accurate.For detecting, former employing " special-purpose model " detects.But this " special-purpose model " also out of true, and kind is many especially, uses and manages all pretty troublesome.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of keystone ring groove center apart from cubing.
The purpose of this utility model is achieved in that it has vernier caliper, it is characterized in that: it also has locating sleeve and measuring jaw, have two covers, every cover is installed on the claw of vernier caliper, specifically: pilot hole is arranged on the locating sleeve, and there is trip bolt the side of pilot hole, and the card claw of measuring jaw and slide calliper rule is inserted in the pilot hole of locating sleeve simultaneously, trip bolt is fixed, and the interior angle of measuring jaw is identical with measured trapezoidal base angle.Like this vernier caliper is placed on trapezoidal closure gasket groove top, two measuring jaws is leaned against on the trapezoidal waist of corresponding sides, on vernier caliper, can read trapezoidal closure gasket groove centre distance.
Compared with prior art, the beneficial effects of the utility model are:
(1) precision is higher, and measurement result accurately and reliably.
(2) simple in structure, easy to use, manufacturing cost is lower.
(3) versatility is good, and every suit cubing can be examined the dovetail groove of tens kinds of different centre distance, can replace the special-purpose model of cover more than 40.Good economy performance.
(4) after dovetail groove detects, unload the measuring jaw vernier caliper and be not subject to any damage, normally use by general cubing.
(5) trapezoidal closure gasket groove centre distance cubing, not only the checker can use, and operator's process is available equally, by process control, reduces unacceptable product; That measures is fast, enhances productivity.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the synoptic diagram that the utility model is measured the trapezoidal closure gasket groove of cylinder.
Fig. 2 is the A portion enlarged drawing among Fig. 1.
Fig. 3 is the synoptic diagram of locating sleeve.
Embodiment
Referring to Fig. 1 and 3, locating sleeve 3 and measuring jaw 1, have two covers, every cover is installed on the claw of vernier caliper 4, specifically: pilot hole 5 is arranged on the locating sleeve, there is trip bolt 2 side of pilot hole, the claw of measuring jaw and slide calliper rule 4 is inserted in the pilot hole of locating sleeve simultaneously, and trip bolt is fixed, referring to Fig. 2, trapezoidal closure gasket groove 6 base angle of cylinder are 113 °, and the internal angle beta of measuring jaw 1 also is 113 °.Like this vernier caliper is placed on trapezoidal closure gasket groove top, two measuring jaws is leaned against on the trapezoidal waist of corresponding sides, on vernier caliper, can read trapezoidal closure gasket groove centre distance.
Claims (2)
1. trapezoidal closure gasket groove centre distance cubing, it has vernier caliper, it is characterized in that: it also has locating sleeve and measuring jaw, have two covers, every cover is installed on the claw of vernier caliper, specifically: pilot hole is arranged on the locating sleeve, there is trip bolt the side of pilot hole, the card claw of measuring jaw and slide calliper rule is inserted in the pilot hole of locating sleeve simultaneously, and trip bolt is fixed, and the interior angle of measuring jaw is identical with measured trapezoidal base angle.
2. according to the described trapezoidal closure gasket groove centre distance cubing of claim 1, it is characterized in that: measured trapezoidal base angle is 113 °.
