Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to a wear detection mechanism for an intermediate shaft pre-installed with an EMES angle positioning tool. Background Art
[0002] The EMES angle positioning fixture is used to secure the yoke and axle tube assembly machine. During intermediate shaft assembly, the initial part angle positioning and length inspection are required to ensure the part does not fit within the EMES angle positioning fixture. A robotic arm then transfers the positioned part into the EMES angle positioning fixture for precise positioning and a second length inspection to prevent inaccurate angle positioning from causing length failures and press-fit dimensions. Before machining begins, the EMES angle positioning fixture is secured to the equipment to ensure that the sub-assembly angles meet the drawing requirements during and after machining, ensuring that the part meets customer requirements for vehicle assembly.
[0003] However, the EMES angle positioning tooling will wear out during use. If the wear is too great, the angle of the intermediate parts will be out of tolerance and unqualified, which will directly affect the customer's loading angle.
[0004] Therefore, it is necessary to design a wear detection mechanism for the EMES angle positioning tooling pre-installed on the intermediate shaft to determine whether the EMES angle positioning tooling is qualified, thereby avoiding the risk of unqualified products being discharged due to the use of unqualified tooling during the intermediate shaft pre-installation process. Summary of the Invention
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a wear detection mechanism for the EMES angle positioning tooling pre-installed on the intermediate shaft to determine whether the EMES angle positioning tooling is qualified, thereby avoiding the risk of unqualified products being discharged due to the use of unqualified tooling during the intermediate shaft pre-installation process.
[0006] In order to achieve the above-mentioned purpose, the utility model is a wear detection mechanism for an intermediate shaft pre-installed with an EMES angle positioning tooling, comprising a base plate, a slide rail, an angle measuring instrument, a connecting flange, a locating pin, a standard part locating pin, and a locating pin fixing structure. An angle measuring instrument is installed at one end of the top of the base plate, the locating pin is inserted into the locating hole of the angle measuring instrument, the measuring end of the angle measuring instrument is connected to the back of the connecting flange, the connecting piece on the surface of the connecting flange is connected to the base of the EMES angle positioning tooling, the tail of the fixed yoke standard part is inserted into the connecting hole of the EMES angle positioning tooling, a slide rail is installed at the other end of the top of the base plate, the setting direction of the slide rail is perpendicular to the measuring surface of the angle measuring instrument, the locating pin fixing structure is slidably connected to the slide rail, and the standard part locating pin passes through the through hole at the end of the fixed yoke standard part and is inserted into the mounting hole at the top of the locating pin fixing structure.
[0007] Handles are provided on both sides of the bottom plate.
[0008] The model of the angle measuring instrument is JLZF-Special-001.
[0009] The upper end of the standard part positioning pin is provided with a boss, which abuts against the upper surface of the end of the fixed yoke standard part.
[0010] Compared with the prior art, the utility model performs spot inspection on the EMES angle positioning tooling through a wear detection mechanism and monitors the service life of the EMES angle positioning tooling through the size of the angle gap, thereby eliminating the potential quality risks of the intermediate shaft product that may be caused by daily wear of the tooling.

[0019] The present invention will now be further described with reference to the accompanying drawings.
[0020] See also Figures 1 to 8The utility model is a wear detection mechanism for an intermediate shaft pre-installed with an EMES angle positioning tooling, comprising a base plate, a slide rail, an angle measuring instrument, a connecting flange, a positioning pin, a standard part positioning pin, and a positioning pin fixing structure. An angle measuring instrument 9 is installed at one end of the top of the base plate 3, and the positioning pin 1 is inserted into the positioning hole of the angle measuring instrument 9. The measuring end of the angle measuring instrument 9 is connected to the back of the connecting flange 2. The connecting piece 21 on the surface of the connecting flange 2 is connected to the base of the EMES angle positioning tooling 4. The tail of the fixed yoke standard part 5 is inserted into the connecting hole of the EMES angle positioning tooling 4. A slide rail 8 is installed at the other end of the top of the base plate 3. The setting direction of the slide rail 8 is perpendicular to the measuring surface of the angle measuring instrument 9. The positioning pin fixing structure 7 is slidably connected to the slide rail 8. The standard part positioning pin 6 passes through the through hole at the end of the fixed yoke standard part 5 and is inserted into the mounting hole 71 at the top of the positioning pin fixing structure 7.
[0021] In order to facilitate the movement of the detection mechanism, handles are provided on both sides of the bottom plate 3.
[0022] The model of the angle measuring instrument 9 is JLZF-Special-001. Other models of angle measuring instruments with positioning holes and a measuring end capable of rotating by connecting with a flange can also be selected.
[0023] A boss 61 is provided at the upper end of the standard part positioning pin 6 , and the boss 61 abuts against the upper surface of the end of the fixed yoke standard part 5 to prevent the fixed yoke standard part 5 from falling off the upper end of the standard part positioning pin 6 .
[0024] When the EMES angle positioning fixture 4 is unused or in a new state, insert the locating pin 1 into the locating hole of the angle measuring instrument 9 to zero the angle measuring instrument 9. Use the connecting flange 2 to connect the EMES angle positioning fixture 4 to the measuring end of the angle measuring instrument 9. Use the standard locating pin 6 to connect the fixed yoke standard component 5 to the locating pin fixing structure 7. Push the locating pin fixing structure 7 along the slide rail 8 to connect the fixed yoke standard component 5 to the EMES angle positioning fixture 4. Turn the EMES angle positioning fixture 4 clockwise and read the initial angle value A0 from the angle measuring instrument 9.
[0025] Before changing over the production line, rotate the EMES angle positioning fixture 4 clockwise and measure the angle value A1. Compare this value with the initial angle value A0 of the EMES angle positioning fixture 4. The difference between the two represents the angular wear of the fixture. If the difference is less than or equal to the dimensional requirement of 1°, the EMES angle positioning fixture 4 is qualified for normal use. If the difference is greater than the dimensional requirement of 1°, the EMES angle positioning fixture 4 should be replaced promptly.
[0026] By comparing the wear amount with the initial value, a relatively accurate measurement can be obtained, making this method suitable for on-site testing. In actual operation, attention should be paid to the operating procedures and the stability of the measurement environment to ensure the reliability of the test results. It is also possible to further improve the accuracy of the measurement by taking the average of multiple measurements.
[0027] The fixed yoke standard part 5 is included in the error-proofing sample management and is annually sent for three-dimensional calibration measurement. The angle measuring instrument can be regularly calibrated using standard gauge blocks or calibration parts to ensure measurement accuracy.
[0028] The utility model performs spot inspection on the EMES angle positioning tooling through the wear detection mechanism and monitors the service life of the EMES angle positioning tooling through the size of the angle gap, thereby eliminating the potential quality risks of the intermediate shaft product that may be caused by daily wear of the tooling.
