Description
Technical field
The present invention relates to measure cubing technical field, specially a kind of crankshaft key slot length detection tool.
Background technology
Engine（Engine）Be it is a kind of can be the machine that can be converted into mechanical energy of other forms.Bent axle is engine
In most important component.It bears the power that connecting rod transmits, and is transformed into torque and is exported and driven on engine by bent axle
Other attachmentes work.Bent axle is common by the centrifugal force of gyrating mass, the gas inertia power of mechanical periodicity and reciprocal inertia force
Effect, makes bent axle bear the effect of flexion torsion load.Keyway is that a slot to match with key is processed on axis or in hole, is used
Carry out installation key, to transmit torque.
During machining crankshafts keyway, the length and size of crankshaft key slot is measured and detected；It uses
When traditional survey tool detects crankshaft key slot, measures complicated and deviation easily occur；Traditional measurement cubing efficiency is used simultaneously
It is low, it can not the efficient size for detecting crankshaft key slot.
Therefore a kind of crankshaft key slot length detection tool is needed, for improving the detection efficiency of crankshaft key slot, while facilitates bent axle
The detection of keyway.

The low problem of shaft detection efficiency.
To achieve the above object, the present invention provides the following technical solutions：A kind of crankshaft key slot length detection tool, including keyway inspection
Block is surveyed, keyway end measuring block and keyway head end measuring block, keyway end measuring block are provided in the keyway detection block
Bottom be provided with keyway end measuring mouth, keyway head end measuring mouth is provided on the left of the keyway head end measuring block, it is described
It is provided with chamfering in keyway detection block.
Preferably, the keyway detection block is L-type block structure.
Preferably, the keyway detection block, keyway end measuring block and keyway head end measuring block are an integral structure.
Preferably, it is provided with graduation mark on the left of the bottom of keyway end measuring block and keyway head end measuring block.
Preferably, there are three the chamfering is arranged altogether, and three chamferings are separately positioned on the upper left side of keyway detection block, the right side
Top and lower right.
Compared with prior art, the beneficial effects of the invention are as follows：The crankshaft key slot length detection tool is scientific and reasonable for structure, uses
It is convenient, it by the measuring mouth on keyway measuring block, conveniently detects whether crankshaft key slot is qualified, improves the effect of crankshaft key slot detection
Rate；By the graduation mark on keyway measuring block, the precision of crankshaft key slot detection is improved, the detection of crankshaft key slot is facilitated；This outcurve
Axle key geosynclinal block is an integral structure, and avoids the crash for measuring key tool, improves the practicability for measuring cubing.
