Description

Motor frame axiality detection device
Technical Field
The utility model belongs to the technical field of the motor detects, concretely relates to motor frame axiality detection device.
Background
The machine base (casing) is an important component of the motor, the coaxiality of the rabbets at the two ends and the inner bore of the machine base is important, and whether the motor operates normally is directly influenced, so that the coaxiality of the machine base (casing) is imperatively detected. The coaxiality of a general engine base is ensured by a machining process, and when the machining process is accidentally fluctuated, a non-coaxial phenomenon occurs, and the current detection method mainly comprises the following steps: firstly, processing a mould matched with a spigot of a machine base on a lathe, knocking the machine base into the machine base without a gap, and detecting the spigot jump of the other end by using a dial indicator so as to determine the coaxiality deviation of the machine base; it has the disadvantages of time and labor waste, inconvenient operation and the like in the process of processing the clamping fixture; detecting by using a three-coordinate measuring instrument; the defects of expensive instrument, large measurement deviation of the workpiece such as re-elliptical deformation and the like exist.
Disclosure of Invention
An object of the utility model is to overcome prior art's shortcoming, provide a motor frame axiality detection device, solve the operation that exists among the prior art and waste time and energy, detect technical problem such as the error is big.
In order to solve the above problem, the utility model discloses a technical scheme be:
the utility model provides a motor frame axiality detection device, is dull and stereotyped, the percentage table including the installation, wherein: the coaxiality detection device of the motor base further comprises a connecting screw rod, a connecting threaded sleeve and a dial indicator mounting rod which are sequentially arranged from top to bottom;
the utility model discloses a dial indicator, including installation flat board, connecting screw, nut, connection swivel nut, dial indicator installation pole, installation flat board, connection screw, connection swivel nut, installation flat board left end be equipped with frame tang step face matched with locating pin, be equipped with a plurality of waist type holes on the installation flat board on locating pin right side, it is fixed through the nut after passing leftmost waist type hole that the upper end of connecting screw, pass through threaded connection between the upper end of connecting screw lower extreme and connection swivel nut, connection.
Further, the length of the installation flat plate is larger than the diameter of the spigot of the motor base.
The utility model adopts the above technical scheme, compare with prior art and have simple structure, with low costs, convenient operation, measure accurate, measurement accuracy not receive advantages such as frame deformation influence.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the installation position of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and fig. 2, the present embodiment includes a mounting plate 1 and a dial indicator 2, wherein: the coaxiality detection device of the motor base further comprises a connecting screw rod 3, a connecting threaded sleeve 4 and a dial indicator mounting rod 5 which are sequentially arranged from top to bottom;
the utility model discloses a dial indicator, including installation dull and stereotyped 1 left end, 6 right sides, connecting screw 3, connecting screw 4, dial indicator installation pole 5, the installation dull and stereotyped 1 left end be equipped with frame tang step face matched with locating pin 6, be equipped with a plurality of waist type holes 7 on the installation dull and stereotyped 1 on locating pin 6 right side, it is fixed through nut 8 after passing leftmost waist type hole 7 that the upper end of connecting screw passes through, pass through threaded connection between 3 lower extremes of connecting screw and the upper end of connecting swivel nut 4, connect swivel nut 4 lower extreme and 5 upper end fixed connection of dial indicator installation pole, the dial indicator 2.
Further, the length of the installation flat plate 1 is larger than the spigot diameter of the motor base.
The utility model discloses a working process and principle:
the base is vertically placed on the platform, the mounting flat plate 1 is flatly placed on the end face of the base spigot, the positioning pin 6 is close to the inner side face of the spigot, the vertical and horizontal distances of the connecting screw rod 3, the connecting screw sleeve 4 and the dial indicator mounting rod 5 are adjusted, the head of the dial indicator 2 is in contact with the surface of the inner chamber and is prepressed by 0.3-0.5 mm, the connecting screw rod 3 is locked by the nut 8, the mounting flat plate 1 is adjusted, the lowest point is found out, the reading of the head pointer is recorded, and then the head pointer is zeroed; and then the device is rotated by 180 degrees left and right, the lowest point of the side wall of the inner bore at the other side is found out by the method, the reading of the pointer at the head of the meter is recorded, and half of the difference of the two readings is the coaxiality of the spigot and the inner bore.
