Abstract
The utility model relate to a tool for detecting a gear, in particular to a tool for detecting the timing angle of a gear. A dial indicator is fixedly arranged on one end of a bottom plate, and a fixed mandrel diameter is arranged on the other end of the bottom plate; the upper end of the fixed mandrel diameter is provided with a workpiece bearing and mounting platform; a pin hole is disposed on the workpiece bearing and mounting platform; a pin hole positioning pin is movably inserted in the pin hole; a rotating crankarm is arranged on the fixed mandrel diameter; and a positioner is arranged on the rotating crankarm. The tool has simple structure and is used for directly judging whether the angle of the gear is up to the standard by fully positioning the gear and recording the value read on the dial indicator. With the design, the tool is suitable for rapidly and correctly detecting the angle of the gear, particularly the bevel gear, and is also suitable for detecting the timing angle of the gear which is positioned by key slots and teeth, particularly the bevel gear.
Description
One, technical field:
The utility model relates to the gear instruments of inspection.
Two, background technology:
Engine timing gear, gear timing angle are very crucial in engine technology, directly influence the burning performance of engine.Pin-and-hole angle requirement ± 15 on gear timing tooth and the wheel hub ' in, conventional detection method is that gear is contained on the axle, be clipped on the universal dividing head then, find the center of pin-and-hole with height gauge, press drawing angular turn dividing head at last to assigned address, on the gear teeth, draw a line with height gauge, whether the range estimation lines are at gear teeth center, thereby definite timing angle ± 15 ' whether qualified, this detection angles error is big, can not directly read numerical value, detecting workpiece wastes time and energy, and overlooker's operative skill is required high, therefore, need a kind of special-purpose angle cubing of design to come detection of gear timing angle.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of time gear angular position cubing is provided, and is simple in structure, detects automatically, and detection speed is fast, precision is high.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of time gear angular position cubing, end fixed installation dial gauge on the base plate, the other end is installed the centering diameter of axle, centering diameter of axle upper end has workpiece and takes up platform, workpiece takes up and has pin-and-hole on the platform, movable plug-in mounting pin-and-hole register pin in the pin-and-hole is installed on the centering diameter of axle and is rotated connecting lever, rotates installation positioner on the connecting lever.
Described dial gauge is fixed on the percentage gauge stand, and the percentage gauge stand is fixed on the base plate.
Described steady arm is made of tooth positioning base and tooth locating shaft, and the tooth positioning seat is fixed on and rotates on the connecting lever, and the tooth locating shaft moves forward and backward in tooth positioning seat mating holes.
The utility model is simple in structure, and the centering diameter of axle is arranged on base plate, by bore and workpiece end face gear is located, five degree of freedom of limiting gear location, with the hole register pin pin-and-hole on the wheel hub is located again, so just limited the six-freedom degree of workpiece, the location fully of having realized workpiece.One of movable set rotates connecting lever on the centering diameter of axle, rotating connecting lever can rotate a steady arm is installed on the connecting lever around the rotation of the centering diameter of axle, and the tooth locating shaft of steady arm is inserted in the teeth groove of gear, like this, just there has been desired angular relationship at pin-and-hole center and gear teeth center on the gear.On the cubing base plate design percentage gauge stand, dial gauge is fixed on the gauge stand, with standard sample to good dial gauge reading.During detection of gear, after gear located fully, the reading value of record dial gauge can judge directly whether the gear angle is qualified.By the design and use of this cubing, not only soon but also accurate, especially spiral gear and gear were suitable equally with the timing angle of keyway and tooth location to the angle cubing that makes gear.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model vertical view.
Five, embodiment:
A kind of time gear angular position cubing as shown in Figure 1, 2, the fixing percentage gauge stand 1 of an end on the base plate 8, dial gauge 9 is fixed on the percentage gauge stand 1, base plate 8 other ends are installed the centering diameter of axle 6, the centering diameter of axle 6 upper ends have workpiece and take up platform 7, workpiece takes up on the platform 7 and has pilot hole, movable plug-in mounting pin-and-hole register pin 5 in the pilot hole, rotate on the centering diameter of axle 6 to install and rotate connecting lever 2, rotate installation positioner on the connecting lever 2, steady arm is made of tooth positioning seat 3 and tooth locating shaft 4, and tooth positioning seat 3 is fixed on and rotates on the connecting lever 2 fixed teeth locating shaft 4 on the tooth positioning seat 3.
Operate in the following order during work:
A) cubing is cleaned lain on the work for inspection platform.
B) guarantee that dial gauge is not loosening, aim at dial gauge, the dial gauge reading is pulled out " 0 " position with standard sample.
C) workpiece 10 is cleaned be placed on the cubing workpiece and take up on the platform, make workpiece wheel hub pin-and-hole relative, register pin is injected in the pilot hole, realize the gear location with pilot hole on the cubing.
D) the tooth locating shaft that rotates on the connecting lever is injected in the teeth groove of gear, at this moment see the dial gauge reading, numerical value is in the 0.60mm scope, and gear timing angle is qualified.
