Description
Technical Field
The utility model relates to a mechanical parts's machining technical field, especially high-efficient stable part conical surface position measurement device and method.
Background
The conical surface position measurement is widely applied to machining of mechanical parts such as crankshafts, and the like, and the conventional production generally adopts a universal measuring tool and a simple auxiliary tool for manual operation, has the defects of low measurement precision, low efficiency and the like, and is not suitable for the requirement of mass production, so that a quick and effective device and method are urgently needed to improve the detection quality and the detection efficiency.
Disclosure of Invention
The utility model aims at providing a simple, economy, effectual conical surface position measurement device realizes the measurement operation to part conical surface position size.
A crankshaft conical surface position measuring device comprises a zero reference base, a conical hole reference disc, a connecting shaft, a dial indicator fixing block and a digital display dial indicator. The connecting shaft is assembled on the taper hole reference disc in an interference manner; the dial indicator fixing block is fastened to the connecting shaft through a screw; the digital display dial indicator is fastened to the dial indicator fixing block through screws. The digital display dial indicator is connected with the taper hole reference disc into a whole through the connecting shaft and the dial indicator fixing block, and the center line of the taper hole reference disc and the center line of the taper surface of the part to be measured are on the same straight line. The taper hole reference disc is provided with an arc hole, a dial indicator fixing block and a connecting shaft, and the axial and radial adjustment can be carried out on the position of a measuring head of the digital display dial indicator. The conical hole reference disc and the zero point reference base are used for zero point calibration of the conical surface position of the digital display dial indicator.
The utility model has the advantages that when the measurement is not carried out, the taper hole reference disc is placed on the zero reference base, the measuring head of the digital display dial indicator contacts with the upper surface of the zero reference base, and the zero button of the dial indicator is touched to carry out zero-returning calibration; when in measurement, the dial indicator is held by a hand, the conical surface of the conical hole reference disc is matched and attached to the conical surface of the part through the conical hole reference disc fixed by the dial indicator fixing block and the connecting shaft, and the indicating numerical value of the dial indicator is the position size of the conical surface of the part. The use and operation are simple, the measurement precision is high, and the measurement efficiency and the product quality are obviously improved.

Detailed Description
As shown in fig. 1-3, a crankshaft conical surface position measuring device comprises a zero reference base 1, a conical hole reference disc 2, a coupling shaft 3, a dial indicator fixing block 4 and a digital display dial indicator 5. The connecting shaft 3 is assembled on the taper hole reference disc 2 in an interference fit mode, the dial indicator fixing block 4 is assembled on the connecting shaft 3, the digital display dial indicator 5 is assembled on the dial indicator fixing block 4, and the connecting shaft 3, the dial indicator fixing block 4 and the digital display dial indicator 5 are fixed into a whole through the hexagon socket head cap screws. The zero reference base 1 is the apparatus base and is used for zero calibration.
The position of the digital display dial indicator 5 can be adjusted through the arc-shaped hole on the taper hole reference disc 2, the connecting shaft 3 and the dial indicator fixing block 4. When in adjustment, 2 socket head cap screws on the dial indicator fixing block 4 are loosened, and the axial and radial adjustment can be carried out on the digital display dial indicator 5.
When the measurement is not carried out, the taper hole reference plate is flatly placed on the zero point reference base 1, a measuring head of the digital display dial indicator 5 is in contact with the upper surface of the zero point reference base 1, a zero point button of the digital display dial indicator 5 is touched and pressed, and zero resetting calibration is carried out; when in measurement, the digital display dial indicator 5 and the taper hole reference disc 2 fixed through the connecting shaft 3 and the dial indicator fixing block 4 are held by hand, the taper hole conical surface of the taper hole reference disc 2 is matched and attached with the conical surface of a part, and the indication value of the digital display dial indicator 5 is the position size of the conical surface of the crankshaft. The adjustment and use operations are not simple, the measurement precision is high, and the measurement yield and the product quality are obviously improved.
The structure and the method can be used for manufacturing a universal and convenient conical surface position size measuring device with low cost, and are suitable for measuring a small crankshaft with high requirements on conical surface position size precision. Use through practice and verify, the device convenient operation presss from both sides tightly reliably, obviously improves the quality of measurement of efficiency and product to reach the utility model discloses the purpose.
