Disclosure of Invention
The utility model discloses to large-scale bent axle consume a large amount of manpowers, detection efficiency is low, measured data are unstable when the circle is beated and is examined to cause the technical problem of the fish tail of bent axle journal easily, provide one kind and reduce operator intensity of labour, improve and detect precision and work efficiency, can also avoid the bent axle to be beated by the large-scale ship class bent axle of fish tail and detect positioner.
Therefore, the technical scheme of the utility model, a large-scale ship level bent axle is beated and is detected positioner, be equipped with the base, be equipped with adjusting bolt on the base, the last V type supporting seat that is equipped with of adjusting bolt, adjusting bolt can be at the base internal rotation, adjusting bolt and V type supporting seat are threaded connection, V type supporting seat is equipped with the intervalve tank, be equipped with support bearing in the intervalve tank, be equipped with the stop collar between support bearing both ends face and the V type supporting seat, be equipped with the supported hole on the V type supporting seat, be equipped with the location axle in the supported hole, support bearing suit is epaxial in the location.
Preferably, the V-shaped supporting seat is provided with a positioning hole, a set screw is arranged in the positioning hole, and the set screw can be screwed on the supporting bearing outer ring.
Preferably, two adjusting bolts are arranged on one base, a fine adjustment bearing is arranged between each adjusting bolt and the corresponding base, the outer ring of each fine adjustment bearing is in interference fit with the corresponding base, and the inner ring of each fine adjustment bearing is in interference fit with the corresponding adjusting bolt.
The utility model has the advantages that when the crankshaft is placed on the device for detection, the height of the crankshaft can be adjusted due to the adjusting bolt; the supporting bearing is arranged, so that the crankshaft can rotate conveniently during detection, and the strength of manual operation is greatly reduced; when needs examine the fixed detection of bent axle position, only need to screw holding screw, can pin the outer lane of support bearing, easily realize the fixed detection of bent axle, above device simple structure, convenient operation, the commonality is high, can greatly improve detection efficiency and degree of accuracy.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a sectional view taken along line a-a of fig. 1.
The symbols in the drawings illustrate that:
1. finely adjusting the bearing; 2, a V-shaped supporting seat; 3. a support bearing; 4. adjusting the bolt; 5. tightening the screw; 6. a limiting sleeve; 7. a base; 8. and (5) positioning the shaft.
Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1-2, a large-scale ship-class crankshaft runout detection positioning device is provided with a base 7, an adjusting bolt 4 is arranged on the base 7, a V-shaped supporting seat 2 is arranged on the adjusting bolt 4, the V-shaped supporting seat 2 is provided with an intermediate groove, a supporting bearing 3 is arranged in the intermediate groove, a limiting sleeve 6 is arranged between two end faces of the supporting bearing 3 and the V-shaped supporting seat 2, the limiting sleeve 6 can prevent the supporting bearing 3 from moving along the left and right, a supporting hole is arranged on the V-shaped supporting seat 2, a positioning shaft 8 is arranged in the supporting hole, the supporting bearing 3 is sleeved on the positioning shaft 8, the limiting sleeve 6 can be sleeved on the positioning shaft 8 with an intermediate hole, and the limiting sleeve 6 can be made into a.
Be equipped with the locating hole on the V type supporting seat 2, be equipped with holding screw 5 in the locating hole, holding screw 5 can be screwed on 3 outer races of support bearing, can be fixed 3 outer races of support bearing through the holding screw 5 of screwing, and then fixed with the bent axle.
Two adjusting bolts 4 are arranged on one base 7, a fine adjustment bearing 1 is arranged between each adjusting bolt 4 and the base 7, the outer ring of each fine adjustment bearing 1 is in interference fit with the base 7, the inner ring of each fine adjustment bearing 1 is in interference fit with the corresponding adjusting bolt 4, and the rotation of the corresponding adjusting bolt 4 in the corresponding base 7 can be realized through the fine adjustment bearing 1. Adjusting bolt 4 and V type supporting seat 2 are threaded connection, rotate adjusting bolt 4 with the spanner and can realize the upper and lower adjustment of V type supporting seat 2, and then realize the altitude mixture control of bent axle.
The fine adjustment bearing 1 adopts a deep groove ball bearing 6308, the support bearing 3 adopts a deep groove ball bearing 6311, the deep groove ball bearing has small starting friction force and strong bearing capacity, an operator can easily rotate the crankshaft, and the requirement of support strength can be completely met for a large crankshaft.
When the technical scheme of this application is used to detect large-scale bent axle, place the positioner of three same specifications on testing platform, place the 1 st main journal, middle main journal and the terminal main journal of the bent axle of being surveyed respectively on the positioner of a same specification, the positioner of middle main shaft can prevent that the bent axle warp and then avoid influencing the detection result that the bent axle beats.
After the crankshaft is placed on the device, the height gauge with the dial indicator is used for measuring the height of the crankshaft, if the heights of the crankshaft in the front, the back and the middle are not consistent, the adjustable wrench can be used for rotating the adjusting bolt 4 in the corresponding positioning device for fine adjustment, and the measurement of the runout is carried out after the central line of the crankshaft is on the same horizontal plane, so that the measurement precision is fully ensured, and the product quality and the reliability are improved.
However, the above description is only an embodiment of the present invention, and the scope of the present invention should not be limited thereto, so that the replacement of the equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should be covered by the claims of the present invention.
