Description
Technical Field
The utility model relates to a motor end cover detection tool, in particular to a motor end cover concentricity detection tool.
Background
In the installation process of the motor end cover, machining errors are formed between the connecting hole positions of the motor end cover and the bearing mounting grooves in the motor end cover, so that slight dislocation is formed between the bearing inner holes of the motor end cover and the motor rotating shaft after the motor end cover and the bearing are installed, and the problem that the rotating shaft cannot be installed or interference noise exists when the rotating shaft rotates, and the installation and the operation stability of the motor are affected.
Therefore, a concentricity detection tool for a motor end cover is needed, so that the position accuracy of a bearing mounting groove and an end cover hole of the motor end cover is detected before the motor end cover is mounted, and the stability of the motor end cover during subsequent mounting and use is improved.
Disclosure of Invention
The utility model aims to provide a concentricity detection tool for a motor end cover. The motor end cover can detect the relative positions of the bearing mounting groove and the end cover hole of the motor end cover.
The technical scheme of the utility model is as follows: the utility model provides a concentricity detection instrument of motor end cover, includes the end cover mounting, is equipped with the mounting hole of connecting motor end cover around the end cover mounting, and the middle part of end cover mounting is equipped with the test hole, and the inboard rotation of test hole is connected with the pivot, and the tip of pivot is equipped with the setting element of cooperation motor end cover.
In the foregoing motor end cover concentricity detection tool, the middle part of the rotating shaft is provided with a rotary disc, the appearance of the rotary disc and the test hole is cylindrical, and the rotary disc and the test hole are mutually attached.
In the above-mentioned concentricity detection tool for motor end cover, the positioning member is a bearing sleeved outside the end part of the rotating shaft.
In the above-mentioned concentricity detection tool for motor end cover, the aperture of the test hole is larger than the outer diameter of the bearing.
In the above-mentioned concentricity detection tool for motor end cover, the handle is arranged at one end of the rotating shaft far away from the positioning piece.
Compared with the prior art, the motor end cover can be fixed on the end cover mounting piece through the mounting holes during testing by the cooperation of the end cover mounting piece, the rotating shaft and the positioning piece, and then the motor end cover extends into the rotating shaft to enable the positioning piece to be buckled with the bearing mounting groove of the motor end cover; the rotary shaft pair is rotated to test, if the rotary disc of the rotary shaft is interfered with the inner wall of the test hole during rotation, the fact that the precision difference exists between the bearing mounting groove of the motor end cover and the end cover hole is indicated, and if the rotary disc can stably rotate in the test hole for one circle, the fact that the precision of the bearing mounting groove and the end cover hole meets the requirement is indicated; under the cooperation, the motor end cover precision detection device can stably realize the precision detection of the motor end cover and is convenient for the operation of manufacturers.
Drawings
FIG. 1 is an outline view of the present utility model;
fig. 2 is a diagram of the connection structure of the present utility model and the motor end cover.
The marks in the drawings are: the device comprises a 1-end cover mounting piece, a 2-mounting hole, a 3-test hole, a 4-rotating shaft, a 5-positioning piece, a 6-rotating disc and a 7-handle.
Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. The concentricity detection tool for the motor end cover is shown in fig. 1, and comprises an end cover mounting piece 1, wherein mounting holes 2 for connecting the motor end cover are formed in the periphery of the end cover mounting piece 1, a test hole 3 is formed in the middle of the end cover mounting piece 1, a rotating shaft 4 is rotatably connected to the inner side of the test hole 3, and a positioning piece 5 matched with the motor end cover is arranged at the end part of the rotating shaft 4; the mounting holes 2 are distributed around the end cover mounting piece 1 in a ring shape by taking the center of the test hole 3 as the center of a circle.
The middle part of pivot 4 is equipped with carousel 6, and the appearance of carousel 6 and test hole 3 is cylindrical, laminates each other and rotates between carousel 6 and the test hole 3 and be connected.
The locating piece 5 is a bearing sleeved on the outer side of the end part of the rotating shaft 4, and the outer diameter of the bearing is consistent with the inner diameter of a bearing mounting groove of the motor end cover.
The aperture of the test hole 3 is larger than the outer diameter of the bearing.
The rotating shaft 4 is provided with a handle 7 at one end far away from the positioning piece 5.
The working principle of the utility model is as follows: during testing, the motor end cover is fixed on the end cover mounting piece 1 through the matching bolts of the end cover holes and the mounting holes 2, and then one end of the rotating shaft 4 passes through the testing holes 3 to enable the positioning piece 5 to be nested in the bearing mounting groove of the motor end cover. After the positioning piece 5 is completely buckled, the turntable 6 and the test hole 3 are mutually aligned and kept in fit; at this time, the tester rotates the rotating shaft 4 through the handle 7, so that the test hole 3 and the rotating disc 6 form relative rotation. If interference occurs in the rotating process of the turntable 6 and continuous action cannot be performed, the machining error exists between the bearing mounting groove and the end cover hole of the motor end cover, and the motor end cover needs to be repaired again; if the turntable 6 can smoothly rotate in the test hole 3 for a circle, the concentricity of the bearing mounting groove and the end cover hole is required to be met, and further the problem of dislocation and clamping stagnation of the motor end cover during subsequent mounting is effectively prevented.
