Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a plug alignment mechanism for testing the air tightness of automotive motors. Background Technology

[0002] In the production process of automotive motors, airtightness testing is a crucial step in ensuring motor quality and performance. Traditional airtightness testing methods often rely on manual alignment of a plug with the motor's air outlet. This is not only labor-intensive but also lacks precision, resulting in low testing efficiency and the potential for improper operation to affect the accuracy of the results. With the rapid development of the automotive industry, the requirements for motor production efficiency and quality are increasing. Traditional manual alignment methods can no longer meet actual production needs, necessitating an automated, high-precision plug alignment mechanism to improve the efficiency and reliability of automotive motor airtightness testing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a plug alignment mechanism for testing the air tightness of automotive motors, so as to improve the efficiency and reliability of testing the air tightness of automotive motors.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a plug alignment mechanism for testing the air tightness of an automotive motor, comprising a vertical support column, a horizontal beam, a horizontal slider, and a vertical slider. A horizontal guide rail is installed parallel to the horizontal beam. The horizontal slider is slidably installed on the horizontal guide rail. A lead screw is vertically installed at the front end of the horizontal slider. An air tightness plug is fixed to the lower end of the lead screw. The air tightness plug is fixedly connected to the vertical slider. The vertical slider is slidably installed on the vertical guide rail. The vertical guide rail is fixed on a vertical support block. The vertical support block is fixedly connected to the horizontal slider.

[0005] Furthermore, a rolling bearing is installed at the connection between the vertical support column and the horizontal beam, allowing the horizontal beam to rotate in a circular motion on the horizontal plane.

[0006] Furthermore, a horizontal extension block is fixed parallel above the horizontal slider, a vertical support block is fixed below the horizontal extension block, and a lead screw passes through the horizontal extension block and is arranged parallel to the vertical support block.

[0007] Furthermore, a rotating disk is installed at the upper end of the lead screw, and a rotating handle is installed on the rotating disk. By rotating the handle, the lead screw can move up and down.

[0008] Furthermore, the airtight plug is fixedly connected to the lead screw on one side and to the vertical slider on the other side via a connector.

[0009] Furthermore, a sealing ring is installed at the end of the airtight plug.

[0010] The beneficial effects of the plug alignment mechanism for testing the air tightness of automotive motors of this utility model are:

[0011] 1. Through the coordinated action of horizontal guide rails, vertical guide rails, and rolling bearings, the airtight plug can move precisely in the horizontal and vertical directions and rotate 360 ​​degrees in the horizontal beam, ensuring that the airtight plug is quickly and accurately aligned with the motor outlet, effectively avoiding detection errors caused by alignment deviations.

[0012] 2. The mechanism has a simple structure and easy-to-understand operation process. Operators only need to rotate the handle to move the airtight plug up and down, without having to manually adjust the position repeatedly. This greatly shortens the test preparation time, improves the overall efficiency of automotive motor airtightness testing, and meets the needs of large-scale automotive motor production.

[0013] 3. Reasonable connection and fixing methods are adopted between various components, such as the fixed connection between the lead screw and the airtight plug and the vertical slider, and the rolling bearing connection between the vertical support column and the horizontal beam, which ensures the stability of the mechanism during operation, reduces the occurrence of equipment failure, and extends the service life of the equipment.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] As shown in the figure, a plug alignment mechanism for testing the air tightness of an automotive motor includes a vertical support column 1, a horizontal beam 3, a horizontal slider 5, and a vertical slider 12. A rolling bearing 2 is installed at the connection between the vertical support column 1 and the horizontal beam 3, so that the horizontal beam 3 can rotate in a circular motion on the horizontal plane.

[0019] A horizontal guide rail 4 is installed parallel to the horizontal beam 3. A horizontal slider 5 is slidably installed on the horizontal guide rail 4. A horizontal extension block 6 is fixed parallel above the horizontal slider 5. A vertical support block 13 is fixed below the horizontal extension block 6. A lead screw 9 passes through the horizontal extension block 6 and is arranged parallel to the vertical support block 13.

[0020] A rotating disk 8 is mounted on the upper end of the lead screw 9, and a rotating handle 7 is mounted on the rotating disk 8. Rotating the handle 7 allows the lead screw 9 to move up and down. An airtight plug 11 is fixed to the lower end of the lead screw 9, and a sealing ring is installed at the end of the airtight plug 11. The airtight plug 11 is fixedly connected to the lead screw 9 on one side and to the vertical slider 12 on the other side via a connector 10. The vertical slider 12 is slidably mounted on a vertical guide rail 14, which is fixed to a vertical support block 13.

[0021] The installation preparation process before implementation is as follows:

[0022] 1. Securely fix the lower end of the vertical support column 1 to the workbench to ensure that it will not shake during subsequent use.

[0023] 2. Install rolling bearing 2 on the upper end of vertical support column 1, and then connect horizontal beam 3 with rolling bearing 2 so that horizontal beam 3 can achieve 360-degree circular rotation in the horizontal plane.

[0024] 3. Install the horizontal guide rail 4 parallel to the horizontal beam 3, and slide the horizontal slider 5 onto the horizontal guide rail 4.

[0025] 4. Fix the horizontal extension block 6 parallel above the horizontal slider 5, fix the vertical support block 13 below the horizontal extension block 6, and fix the vertical guide rail 14 on the vertical support block 13.

[0026] 5. Slide the vertical slider 12 onto the vertical guide rail 14, install the rotating disk 8 on the horizontal extension block 6, install the rotating handle 7 on the rotating disk 8, connect the upper end of the lead screw 9 to the rotating disk 8, and pass through the horizontal extension block 6 at the lower end. It is fixedly connected to one side of the airtight plug 11 through the connector 10. The other side of the airtight plug 11 is fixedly connected to the vertical slider 12, and a sealing ring is installed at the end of the airtight plug 11.

[0027] The implementation process is as follows:

[0028] 1. Horizontal adjustment: Based on the position of the motor's air outlet, rotate the horizontal beam 3 to make it rotate to a suitable angle in the horizontal plane to initially adjust the horizontal position of the airtight plug 11.

[0029] 2. Front and rear position adjustment: Push the horizontal slider 5 to slide along the horizontal guide rail 4, which will drive the horizontal extension block 6, vertical support block 13, vertical guide rail 14, vertical slider 12 and airtight plug 11 to move together in the horizontal direction, so as to make the front and rear position of the airtight plug 11 in the horizontal direction fine adjustment, so that it is close to the front and rear position of the motor air outlet.

[0030] 3. Adjustment of vertical position: The operator holds the rotating handle 7 and rotates the rotating disk 8 clockwise or counterclockwise. The rotating disk 8 drives the lead screw 9 to move up and down. The lead screw 9 drives the airtight plug 11 to move up and down through the connecting piece 10. At the same time, since the airtight plug 11 is fixedly connected to the vertical slider 12, the vertical slider 12 will slide up and down synchronously along the vertical guide rail 14 to further and accurately adjust the vertical position of the airtight plug 11 until the sealing ring of the airtight plug 11 is tightly fitted to the motor air outlet.

[0031] 4. Air tightness test: After the air tightness plug 11 is aligned with the air outlet of the motor, the motor is inflated with air using relevant equipment. The air tightness of the motor is then tested using an air tightness tester. After the test is completed, the rotating handle 7 is rotated in the opposite direction to remove the air tightness plug 11, thus completing one test operation.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
