Description

Technical Field

[0001] This utility model belongs to the field of calibration fixture technology, and in particular relates to an EROWA calibration fixture. Background Technology

[0002] The principle of EROWA calibration fixtures is mainly based on their precise mechanical structure and positioning system to ensure the accuracy and repeatability of workpieces during the machining process.

[0003] However, existing EROWA calibration fixtures have many drawbacks. EROWA fixtures are usually placed directly on marble. Under normal circumstances, the flatness of marble has tolerances, and the accuracy of EROWA fixtures depends on the fixture feet. It is only possible to detect which foot is uneven by feeling. Without the support of accurate data, deviations are easily generated, which in turn affects the detection accuracy. Therefore, we propose an EROWA calibration fixture. Utility Model Content

[0004] The purpose of this invention is to provide an EROWA calibration fixture. By setting a dial indicator probe, specifically by loosening the dial indicator fixing screw to allow the mounting block to move up and down, the height of the dial indicator can be adjusted, thereby adjusting the height of the dial indicator probe. The dial indicator probe is positioned 0.1 mm above the testing fixture. The EROWA fixture is placed on the testing fixture, and the height of each EROWA fixture foot is recorded. This allows for the correction of each EROWA fixture foot to a uniform height, ensuring the accuracy of the EROWA fixture. This invention solves many shortcomings of existing EROWA calibration fixtures. EROWA fixtures are usually placed directly on marble, and the flatness of marble generally has tolerances. Furthermore, the accuracy of the EROWA fixture depends on the fixture foot, and the detection of uneven foot can only be done by feel, without accurate data support, which easily leads to deviations and affects the testing accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an EROWA calibration fixture, including a marble platform, the top of which contacts a detection fixture seat;

[0007] Two vertical bars are fixedly connected to the top right side of the testing fixture base. A mounting block is slidably inserted into one side of the two vertical bars opposite each other. Each of the front vertical bars has a mounting hole, and a dial indicator fixing screw is threaded into the mounting hole. A dial indicator is fixedly connected to the right side of the mounting block. A dial indicator is fixedly connected to the top of the dial indicator. A testing fixture is fixedly connected to the top of the testing fixture base. The testing fixture is disc-shaped. The height of the dial indicator probe can be freely adjusted by the dial indicator fixing screw to better meet the measurement needs of different situations.

[0008] Furthermore, the testing fixture has a test hole inside, which is inserted into the outer surface of a dial indicator probe. An EROWA fixture is set on top of the testing fixture, and four EROWA fixture feet are fixedly connected to the bottom of the EROWA fixture. The bottom of the EROWA fixture feet contacts the top of the testing fixture, and the top of the EROWA fixture contacts a copper electrode. By moving the EROWA fixture feet, the height of each EROWA fixture foot is recorded, thereby obtaining the height of each EROWA fixture foot and correcting it to be the same, ensuring the accuracy of the EROWA fixture.

[0009] Furthermore, the top of the EROWA fixture has two slidably connected clamps. The opposite sides of the two clamps contact the left and right surfaces of the copper electrode. Handles are fixedly connected to the opposite sides of the two clamps. Two sliding grooves are formed on the inner side of the top of the EROWA fixture. A sliding rod is fixedly connected inside the sliding groove. A moving ring is slidably connected to the outer surface of the sliding rod. The top of the moving ring is fixedly connected to the bottom of the clamp. Four springs are fixedly connected inside the sliding groove. The side of the springs closest to the copper electrode contacts the surface of the moving ring. The clamps can effectively fix the copper electrode and prevent slight movements during the testing process from causing the center of gravity of the EROWA fixture to deviate, thus affecting the measurement accuracy.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model uses a dial indicator probe. Specifically, by loosening the dial indicator fixing screws to allow the mounting block to move up and down, the height of the dial indicator can be adjusted, thereby adjusting the height of the dial indicator probe. The dial indicator probe is 0.1 mm higher than the testing fixture. The EROWA fixture is placed on the testing fixture, and the height of each EROWA fixture foot is recorded. The height of each EROWA fixture foot is then corrected to be the same, ensuring the accuracy of the EROWA fixture.

[0012] 2. This utility model, by setting up a dial indicator, specifically, only requires placing the EROWA fixture on the testing fixture, aligning the EROWA fixture feet with the dial indicator probe, and then ensuring that the four EROWA fixture feet are at the same height, greatly reducing the difficulty of operation and eliminating the need for professional inspectors.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5As shown, this utility model is an EROWA calibration fixture, including a marble platform 8, with a detection fixture seat 7 in contact with the top of the marble platform 8;

[0024] Two vertical bars 71 are fixedly connected to the top right side of the testing fixture base 7. A mounting block 61 is slidably inserted into the opposite side of the two vertical bars 71. Each of the front vertical bars 71 has a mounting hole, and a dial indicator fixing screw 9 is threaded into the mounting hole. A dial indicator 6 is fixedly connected to the right side of the mounting block 61. A dial indicator 6 is fixedly connected to the top of the dial indicator 6. A testing fixture 4 is fixedly connected to the top of the testing fixture base 7. The testing fixture 4 is disc-shaped. By setting up the dial indicator 6, this utility model only requires placing the EROWA fixture 2 on the testing fixture 4, aligning the EROWA fixture feet 3 with the dial indicator probe 5, and then ensuring that the four EROWA fixture feet 3 are at the same height. This greatly reduces the difficulty of operation and does not require a professional inspector.

[0025] The testing fixture 4 has a test hole inside, which is inserted into the outer surface of the dial indicator probe 5. An EROWA fixture 2 is set on top of the testing fixture 4. Four EROWA fixture feet 3 are fixedly connected to the bottom of the EROWA fixture 2. The bottom of the EROWA fixture feet 3 contacts the top of the testing fixture 4, and the top of the EROWA fixture 2 contacts a copper electrode 1. This utility model adjusts the height of the dial indicator 6 by loosening the dial indicator fixing screw 9 so that the mounting block 61 can move up and down. This adjusts the height of the dial indicator 6, thereby adjusting the height of the dial indicator probe 5. The dial indicator probe 5 is 0.1 mm higher than the testing fixture 4. The EROWA fixture 2 is placed on the testing fixture 4, and the height of each EROWA fixture foot 3 is recorded by moving it. The height of each EROWA fixture foot 3 is then corrected to be the same, ensuring the accuracy of the EROWA fixture 2.

[0026] The top of the EROWA fixture 2 has two sliding plates 22. The opposite sides of the two plates 22 are in contact with the left and right surfaces of the copper electrode 1. The opposite sides of the two plates 22 are fixedly connected to handles 23. The top inner side of the EROWA fixture 2 has two sliding grooves. The sliding rods 24 are fixedly connected inside the sliding grooves. The outer surface of the sliding rods 24 is slidably connected to a moving ring. The top of the moving ring is fixedly connected to the bottom of the plates 22. The sliding grooves have four springs 21 fixedly connected inside. The side of the springs 21 closest to the copper electrode 1 is in contact with the surface of the moving ring.

[0027] A specific application of this embodiment is as follows: First, the marble platform 8 is placed to provide a stable reference surface for the subsequent testing work. Next, preparation of the testing fixture begins. The testing fixture base 7 is gently placed on the marble platform 8, and the testing fixture 4 is also placed on the testing fixture base 7. Next, the dial indicator 6 is adjusted to zero. Then, the EROWA fixture 2 is placed on the testing fixture 4. Next, the two handles 23 are pulled outwards, causing the clamping plate 22 to move outwards. This step is to facilitate placing the copper electrode 1 on the EROWA fixture 2. After placing the copper electrode 1 on the EROWA fixture 2, the clamping plate 22 is released. At this time, the elastic force of spring 21 takes effect, driving the moving ring to move, which in turn drives the clamping plate 22 to clamp the copper electrode 1. Then, the dial indicator fixing screw 9 is loosened with a screwdriver, and the height of the dial indicator 6 is adjusted. The height of the dial indicator 6 is carefully adjusted. Next, the EROWA fixture foot pin 3 is moved to align with the dial indicator probe 5, and the operation is repeated multiple times. During each operation, the reading of the dial indicator 6 is recorded to ensure the accuracy and reliability of the data. By repeating the operation multiple times and recording the data of each foot pin, we can gain a more comprehensive understanding of the flatness and accuracy of the EROWA fixture 2. Finally, we compare and analyze the recorded data to draw conclusions.
