Abstract
The utility model relates to a crankshaft semicircular keyway depth detection tool. The crankshaft semicircular keyway depth detection tool comprises a base, a depth dialgage, and a set screw. A circular through hole is formed in the central portion of the base vertically. A screw hole is formed in the side surface of the base. The bottom surface of the base is an arc surface, wherein the arc surface is matched with the shaft neck surface of a crankshaft located at the position of a crankshaft semicircular keyway. The measuring rod of the depth dialgage is inserted into the circular through hole, and the side surface of the depth dialgage is fixed with the screw hole through the set screw in a matching and compacting manner. According to the utility model, simple construction, convenient and reliable utilization and accurate depth measurement can be realized, and fast measurements can be realized. The crankshaft semicircular keyway depth detection tool is suitable for semicircular keyway or flat key keyway depth measurements of various shafts.
Description
Technical field
The utility model relates to axial workpiece keyway dimension measuring device, specifically bent axle Woodruff key slots and keyways depth detection instrument.
Background technology
We know, the belt pulley of installing the microcephaly of engine crankshaft, and circumferentially woodruff key commonly used is fixed.Therefore on the bent axle finished figure, the keyway dimensional accuracy is claimed.In order to meet the processing technology requirement, except being controlled by equipment in process, also need its depth dimensions is measured and checked.Normally with vernier caliper or pit gauge, measure, owing to surveying chi head and the loose contact of keyway extreme lower position, cause measuring error larger.And use vernier caliper or pit gauge to measure, operation is also inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, manufacture simply, and simple operation, detection efficiency is high, measures reliably bent axle Woodruff key slots and keyways depth detection instrument accurately.
The technical scheme in the invention for solving the above technical problem is: a kind of bent axle Woodruff key slots and keyways depth detection instrument, it comprises pedestal, degree of depth dial gauge, gib screw, it is characterized in that: described pedestal intermediate vertical is provided with a manhole, side is provided with a screw, base bottom surface is arc surface, and the crankshaft journal surface of this arc surface and bent axle Woodruff key slots and keyways present position matches; The sounding rod of described degree of depth dial gauge inserts in manhole, and side coordinates and is fixed with screw by gib screw.
When the utility model is used, the pedestal of hand-held testing tool, engage the pedestal arc surface simultaneously and be adjacent to the crankshaft journal surface corresponding at the bent axle Woodruff key slots and keyways together with the measuring head of degree of depth dial gauge, writes down the reading of degree of depth dial gauge.Then the pedestal arc surface continues to be adjacent to journal surface, moves to the Woodruff key slots and keyways present position, and the measuring head of degree of depth dial gauge stretches out manhole, reaches the bottom of Woodruff key slots and keyways, again writes down the reading of degree of depth dial gauge.Twice survey measurements is poor, is the degree of depth of bent axle Woodruff key slots and keyways.Can realize convenience, depth survey accurately.
The utility model is by a pedestal matched with the crankshaft journal surface of bent axle Woodruff key slots and keyways present position is set, and this pedestal is testing tool and the main body that engages of bent axle cooperation.And can make the pedestal of different size by the crankshaft journal size.Against existing technologies, the utility model simple structure, easy to use, reliable, depth survey is accurate, can realize Quick Measurement.A kind of desirable bent axle Woodruff key slots and keyways depth detection instrument, applicable various axle class Woodruff key slots and keyways or the depth survey of flat key keyway.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is that the assembly structure master of a kind of measuring state of the utility model looks schematic diagram.
Fig. 2 is that schematic diagram is looked on the assembly structure left side of the another kind of measuring state of the utility model.
Label in figure is: 1. degree of depth dial gauge, 2. gib screw, 3. pedestal, 4. bent axle.
Embodiment
Fig. 1 is that the assembly structure master of the measuring state of the utility model measuring head while reaching the bottom position of Woodruff key slots and keyways looks schematic diagram.Schematic diagram is looked on the assembly structure left side of measuring state when Fig. 2 is the utility model measuring head contact Woodruff key slots and keyways journal surface of living in.
From Fig. 1 and Fig. 2, can find out, a kind of bent axle Woodruff key slots and keyways depth detection instrument, it comprises pedestal 3, degree of depth dial gauge 1, gib screw 2, and described pedestal 3 is square body, and to be testing tool coordinate with bent axle engages main body for it.Pedestal 3 intermediate vertical are provided with a manhole, and side is provided with a screw, and pedestal 3 bottom surfaces are arc surface, and bent axle 4 journal surface of this arc surface and bent axle Woodruff key slots and keyways present position match; The sounding rod of described degree of depth dial gauge 1 inserts in manhole, and side coordinates and is fixed with screw by gib screw 2.
When the utility model is used, the pedestal 3 of hand-held testing tool, engage pedestal 3 arc surfaces simultaneously and be adjacent to the bent axle corresponding at the bent axle Woodruff key slots and keyways 4 journal surface together with the measuring head of degree of depth dial gauge 1, as shown in Figure 2, writes down the reading of degree of depth dial gauge 1.Then the pedestal arc surface continues to be adjacent to journal surface, moves to the Woodruff key slots and keyways present position, and the extended manhole of the measuring head of degree of depth dial gauge 1 reaches the bottom of Woodruff key slots and keyways, as shown in Figure 1, again writes down the reading of degree of depth dial gauge.Twice survey measurements is poor, is the degree of depth of bent axle Woodruff key slots and keyways.
The utility model simple structure, simple operation, reliable, can realize convenience, depth survey accurately.Can make the pedestal of different size by the crankshaft journal size, applicable various axle class Woodruff key slots and keyways or the depth survey of flat key keyway.
