Description
Technical field
The utility model relates to testing tool manufacturing technology field, especially a kind of cubing of the dedicated test depth of parallelism of the fuselage for compressor.
Background technology
Fuselage is one of important parts of piston compressor, plays to bear support various movement parts and guarantee its position relationship effect.Therefore, the manufacturing accuracy of fuselage directly affects the installation quality of compressor.A kind of fuselage of compressor; The fuselage top is provided with two tilting middle body mounting planes, vertical towards being provided with skidway hole with middle body mounting plane; Be located at clutch shaft bearing hole and the second dead eye on fuselage; Between these planes and hole, the related of dimensional tolerence and form and position tolerance arranged; Wherein middle body mounting plane is one of important indicator that detects the fuselage form and position tolerance to the dead eye axis parallel degree, because body volume is huge, and complex structure, dimensional tolerence can be measured; Form and position tolerance uses conventional cubing to be difficult to measure, and need just can measure with special three-coordinates measuring machine, but special three-coordinates measuring machine cost is high, does not generally adopt; The precision of form and position tolerance all relies on equipment precision to ensure for a long time, this also is unfavorable for the quality control of product in manufacture process, in existing fuselage Parallel testing method, also do not have a kind of cubing and detection means to go for above-mentioned fuselage, many enterprises and forefathers solve the middle body mounting plane of this fuselage to dead eye axis parallel degree measuring method and means, carried out a large amount of tests, a kind of suitable process means of acquisition and method have not been arranged so far.
The utility model content
Technical problem to be solved in the utility model is to provide accurate, the quick checking fixture for parallelism that the middle body mounting plane of fuselage is detected the dead eye axis parallel degree of a kind of energy.
The technical scheme that the utility model technical solution problem adopts is: the technical scheme that the utility model technical solution problem adopts is: this checking fixture for parallelism comprises dial gauge, a leveling ruler is arranged, described leveling ruler bottom is provided with the first table bar and the second table bar, described the first table bar and described the second table bar include the table post and are inserted into the interior vertical supporting rod of described table post, described vertical supporting rod end is provided with clamp, described vertical supporting rod is equipped with supporting rod by clamp, and described supporting rod has clamped dial gauge.
In above-mentioned checking fixture for parallelism technical scheme, technical scheme can also be more specifically: described vertical supporting rod and described supporting rod are vertical setting.
Further, described table post is contained on described leveling ruler by screw thread.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect that has is the utility model: 1, the utility model can fast be measured simple, practical to the middle body mounting plane of body to the dead eye axis parallel degree; 2, can control the dead eye axis parallel degree the middle body mounting plane of fuselage, for the installation quality that improves compressor provides technical guarantee.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Checking fixture for parallelism as shown in Figure 1 comprises the first dial gauge 6 and the second dial gauge 7; There is a bottom to establish the leveling ruler 1 of a plurality of threaded holes, at the place, close two ends of leveling ruler 1 bottom, the first table bar and the second table bar are housed respectively, the first table bar has table post 2 and is inserted into the interior vertical supporting rod 4 of table post 2, the end of vertical supporting rod 4 is provided with clamp, vertical supporting rod 4 is equipped with supporting rod 5 by its clamp, vertical supporting rod 4 is vertical setting with supporting rod 5, and supporting rod 5 has clamped dial gauge 6; One end of table post 2 is the screw rod that is provided with one section screw thread, and table post 2 is contained in the bottom of close leveling ruler 1 one ends by screw rod.The second table bar has table post 10 and is inserted into the interior vertical supporting rod 9 of table post 10, and the end of vertical supporting rod 9 is provided with clamp, and vertical supporting rod 9 is equipped with supporting rod 8 by clamp, and vertical supporting rod 9 is vertical setting with supporting rod 8, and supporting rod 8 has clamped dial gauge 7; One end of table post 10 is the screw rod that is provided with one section screw thread, and table post 10 is contained in the bottom of close leveling ruler 1 other end by screw rod.
Fuselage as shown in Figure 2 and Figure 3 has tilting middle body mounting plane b in the both sides, top respectively, and axis a is parallel to clutch shaft bearing hole a1 and the second dead eye a2 of middle body mounting plane b; Middle body mounting plane be 0.06 to the requirement of dead eye axis parallel degree.
During work, by stent support, that fuselage is tilting, the middle body mounting plane b of fuselage is the level of state; Leveling ruler 1 is placed on the middle body mounting plane b of fuselage, the first table bar is positioned at the clutch shaft bearing hole a1 side of fuselage, and the second table bar is positioned at the second dead eye a2 side of fuselage; The first table bar is proofreaied and correct with the first adjustable stem 3, and the second table bar is proofreaied and correct with the second adjustable stem 11, as shown in Figure 4; Leveling ruler 1 is carried out laterally on the middle body mounting plane b of fuselage and stringer is moved, measure respectively to such an extent that the middle body mounting plane b of fuselage is 345.087 millimeters to the numerical value of a1 top, clutch shaft bearing hole distance L 1, the numerical value of middle body mounting plane b to the second dead eye a2 top distance L 2 of fuselage is 425.01 millimeters; Measure respectively to such an extent that the numerical value of clutch shaft bearing hole work a1 inner diameter D 1 is 400.025 millimeters, the numerical value of the second dead eye a2 inner diameter D 2 is 240.02 millimeters; The numerical value of diameter d that measures the middle body mounting plane b of described fuselage is 500 millimeters; Numerical value apart from B between clutch shaft bearing hole a1 and the outside, the second dead eye a2 two ends is 590 millimeters; As shown in Figure 5.The middle body mounting plane of fuselage is [L1+D1/2-(L2+D2/2)] * d/B to dead eye axis parallel degree e, brings measured numerical value into calculating formula:
