Description
TECHNICAL FIELD
[0001] The utility model relates to the blade edge angle tester used in the blade processing process, specifically to an angle reset fine adjustment mechanism for blade edge angle tester. BACKGROUND
[0002] It is known in the blade processing field that the blade edge angle needs to be sampled and detected after the blade edge is processed to see whether it meets the specification requirements, at which time the blade edge angle tester needs to be used.
[0003] The applicant filed a utility model patent application with the application number 2025206855350 and the name "a visual blade edge angle tester" on April 12, 2025. The blade edge angle tester of this application adds an encoder and an industrial computer to the manual tester in the prior art. In the testing state, the level meter no longer needs to be placed on the test rod, which can improve the stability and working efficiency of the tester. Therefore, it needs to periodically reset the reference position of the test rod's rotation angle with the help of the level meter and make the display of the industrial computer and the level meter consistent by using the encoder, thereby improving the measurement accuracy of the blade edge angle tester. The angle reset mechanism of this blade edge angle tester includes a limiting rod, which is arranged on the rotating shaft connected to the test rod and is perpendicular to the rotating shaft. A first limiting block is fixed above the limiting rod when it is rotated to the horizontal position, and a second limiting block is fixed behind the limiting rod when it is rotated to the vertical position. The first limiting block and the second limiting block can limit the range of rotation of the limiting rod, reduce the rotation stroke of the rotating shaft, and reduce the wear of the components caused by excessive rotation of the test rod. When resetting the reference position of the test rod's rotation angle, place the level meter on the rotating end of the test rod, rotate the test rod to the horizontal position, and the limiting rod will rotate to the horizontal position at the same time and abut against the first limiting block. Observe whether the angle displayed on the level meter and the industrial computer is consistent at this time. Under normal conditions, the angle displayed on the level meter at this time should be 0 degrees. If there is a deviation in the angle displayed on the industrial computer, use the encoder to reset it to zero to make the displays of the level meter and the industrial computer consistent. Similarly, rotate the test rod to the vertical position, and the limiting rod will rotate to the vertical position at the same time and abut against the second limiting block. Observe whether the angle displayed on the level meter and the industrial computer is consistent at this time. Under normal conditions, the angle displayed on the level meter at this time should be 90 degrees. If there is a deviation in the angle displayed on the industrial computer, use the encoder to reset it to 90 degrees to make the displays of the level meter and the industrial computer consistent. Both of these two kinds of reference position adjustment are called reset adjustment.
[0004] However, no matter the first limiting block or the second limiting block, there is a possibility of position deviation during installation. If a negative angle occurs when the limiting rod abuts against the first limiting block, or an angle greater than 90 degrees occurs when the limiting rod abuts against the second limiting block, the operator needs to find the 0-degree and 90-degree reference positions by slightly rotating the test rod and using the human eye, which undoubtedly increases the difficulty of resetting and debugging. If an angle greater than 0 degrees occurs when the limiting rod abuts against the first limiting block, or an angle less than 90 degrees occurs when the limiting rod abuts against the second limiting block, the first limiting block or the second limiting block needs to be reinstalled or ground, so as to find the 0-degree and 90-degree reference positions, which not only increases the difficulty of resetting and debugging, but also wastes a large amount of manpower and time cost, which is not worth the loss. At the same time, even if the 0-degree and 90-degree reference positions are found, after the test rod is rotated for a large angle for a plurality of times, the travel loss of the test rod is increased due to the friction between mechanical components or the influence of processing precision, so that the test result deviates from the actual blade angle, which affects the test precision.

[0008] The adjusting end of the first adjusting screw protrudes above the first screw seat, the lower end of the first adjusting screw protrudes below the first screw seat and is threaded.
[0009] The first sliding block is fixed outside the first slide, so that the first limiting block and the first slide are in sliding fit.

The limiting rod and the second limiting block are in the same vertical plane, and when the limiting rod is rotated to the vertical position, the outer end edge thereof is located in the vertical plane projection of the second limiting block.
[0011] The adjusting end of the first adjusting screw protrudes above the first screw seat, the lower end of the first adjusting screw protrudes below the first screw seat and is threaded.

The limiting rod 13 and the first limiting block 5 are located in the same vertical plane, and when the limiting rod 13 is rotated to a horizontal position, the outer end edge thereof is located in the horizontal plane projection of the first limiting block 5. The adjusting end of the first adjusting screw 8 extends above the first bolt seat 7, the lower end of the first adjusting screw 8 extends below the first bolt seat 7 and is processed with threads thereon. The first limiting block 5 is processed with a vertical threaded hole, and the threaded hole of the first limiting block 5 is matched with the threads of the lower end of the first adjusting screw 8. The first sliding rail 3 has a first sliding block 4, and the first limiting block 5 is fixed outside the first sliding block 4, so that the first limiting block 5 is in sliding fit with the first sliding rail 3.
[0022] The support plate 1 has a second slide rail 14 arranged transversely below the end of the rotating shaft 12 corresponding to the limiting rod 13. The rear end of the second slide rail 14 has a second bolt seat 18, and the second bolt seat 18 has a second adjusting bolt 17 arranged transversely.

Through the above two steps, the reset debugging of the reference position can be completed. The method is simple in operation, can reduce the influence of human factors on the reset debugging, reduces the difficulty of the reset debugging, and reduces the loss of human and time cost. At the same time, when a larger angle needs to be tested, the first adjusting bolt 8 can be rotated, so that the abutting position of the limiting rod 13 and the first limiting block 5 is slightly smaller than the test angle (for example, when the test angle is 12 degrees, the small angle reference position can be debugged to 10 degrees), or the second adjusting bolt 17 can be rotated, so that the abutting position of the limiting rod 13 and the second limiting block 16 is slightly larger than the test angle (for example, when the test angle is 76 degrees, the large angle reference position can be debugged to 80 degrees). By reducing the debugging range of the reference position, the rotating stroke of the test rod 9 during testing can be reduced, the friction between mechanical parts can be reduced, and the stroke loss can be reduced, so that the test precision of the blade angle tester can be greatly improved.
