[0002] The flange fork and the universal joint fork cooperate with the transmission shaft, which is a common structure in the mechanical field.

[0003] During the production of flange forks and universal joint forks, the main parameters that need to be tested are ear hole symmetry, ear surface symmetry, ear side symmetry, ear hole parallelism, ear tip parallelism, ear hole center height and total height. Due to their complex structure, each parameter needs to be tested with different inspection tools.

[0004] At present, most flange fork inspections are done manually, which is inefficient and inaccurate. When using a measuring tool such as a three-dimensional coordinate measuring machine for inspection, on the one hand, the price is very expensive, and on the other hand, a single measuring tool requires the use of other stable components to assist in the inspection, resulting in insufficient accuracy and difficult operation, which is not practical on the production line.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0033] A multifunctional detection system, comprising: a parallelism detection component 1, such as Figure 1 and Figure 2 As shown, it includes a first base 11, a first mounting portion 12 and a detection portion 13. The first mounting portion 12 is welded on the first base 11. The first mounting portion 12 is in the shape of a hollow shell. The detection portion 13 is slidably connected to the first mounting portion 12. The lower portion of the detection portion 13 is a planar structure. The detection portion 13 is in direct contact with the workpiece. A slide groove is provided on one side of the first mounting portion 12. The detection portion 13 is located in the slide groove and can slide. Therefore, when the workpiece to be tested is placed on the first base 11, the detection portion 13 can be adjusted to the distance to the workpiece to be tested under the restriction of the first mounting portion 12. The parallelism detection assembly 1 also includes a placement block 14 and a positioning rod that can be inserted into the hole of the product to be tested. The positioning rod is a standard part, that is, it is polished into a cylindrical shape to match the hole of the product. There is a circular protrusion at the bottom of the flange fork. A positioning hole is provided on the placement block 14 for the protrusion of the product to be tested to be placed, so that when the placement block 14 is moved, the positioning rod can move on the surface of the detection portion 13. The parallelism detection method includes the following steps: first, measure the height of the positioning rod and the placement block 14 stacked together, observe the real-time value displayed on the display screen, and record it as d1; then measure the direct parallelism between the positioning rod and the placement block 14 of the product to be tested, use the positioning rod to pass through the product to be tested, place the product to be tested on the placement block 14 on the first base 11, move the placement block 14 along the axis of the positioning rod under the detection part 13, and the detection part 13 moves on the upper surface of the positioning rod, observe the real-time value displayed on the display screen, and record it as d2, define parallelism c=d2-d1, and compare c with the standard value.

[0034] Symmetry detection component 2, such as Figure 3 and Figure 4As shown, it includes a second base 21, a moving part 22 and a positioning part 23. The positioning part 23 is installed on one side of the second base 21 near the end. The positioning part 23 can be adjusted to the height of the moving part 22 according to the size of the product to be tested. The moving part 22 is used to place the component to be tested. The moving part 22 is slidably connected to the second base 21 so that when the moving part 22 is pushed, the component to be tested can be pressed against one side of the positioning part 23. In the present invention, the first base 11 and the second base 21 can be existing flat plate structures. The method of symmetry detection: the workpiece to be tested after parallelism detection is placed on the moving part 22, one side of the bottom of the product to be tested is supported on the support 223, the height of the positioning block 231 is adjusted, and then the moving part 22 is moved to press one side of the product to be tested against the positioning block 231, and the real-time value displayed on the display screen is observed, and then the product to be tested is removed, and another side is changed for measurement, and then the other two sides of the product to be tested are measured in turn (the shape of the flange fork is an existing structure), and the detected value is compared with the standard value. In actual use, the parallelism of the product to be tested can be detected first, or the symmetry of the product to be tested can be detected first, and there is no order of priority between the two.

[0035] In order to display the results more intuitively, the detection system of the present invention also includes a display component, which includes a display screen. The parallelism detection component 1 and the symmetry detection component 2 both include a grating ruler 3. Specifically, the grating ruler 3 of the parallelism detection component 1 is installed in the first installation part 12, and the grating ruler 3 is connected to the detection part 13. The movement data of the detection part 13 can be transmitted to the display screen through the grating ruler 3. The grating ruler 3 of the symmetry detection component 2 is installed on the second base 21, and the grating ruler 3 is connected to the moving part 22. In this way, when the product size changes, the moving platform 221 will move relative to the positioning block 231, and the movement data of the moving platform 221 can be transmitted to the display screen through the grating ruler 3.

[0036] Furthermore, the positioning component 23 includes a positioning block 231, a second mounting portion 232 and an adjusting wheel 233. The adjusting wheel 233 is threadedly connected to the positioning block 231 after passing through a sliding hole provided on the second mounting portion 232. The positioning block 231 and the second mounting portion 232 are both provided with bar teeth on the side close to each other, so that when the adjusting wheel 233 is rotated, the distance between the positioning block 231 and the adjusting wheel 233 can be reduced, thereby fixing the positioning block 231 and the second mounting portion 232, and when the movable component 22 is moved, the product to be tested on its upper portion can be against one side of the positioning block 231. In order to better detect and support the product to be tested, the moving component 22 includes a moving platform 221, a sliding part 222 and a support member 223. The sliding part 222 is installed at the lower part of the moving platform 221. Two parallel slide rails 211 are designed on the second base 21. The moving component 22 is slidably connected to the second base 21 through the slide rails 211. The upper part of the moving platform 221 extends upward to form a limiting part 224 that pushes the product to be tested toward the positioning component 23. A triangular groove for placing the product to be tested is opened on one side of the limiting part 224 close to the positioning block 231. The limiting part 224 is connected to the side close to the positioning part 23 with the support member 223. There are two support members 223, which are symmetrical with the middle of the moving platform 221. Each support member 223 is hinged on the limiting part 224 through a hinge hole opened on the upper part, and the hinge hole is in the shape of a bar. There is a certain damping between the support member 223 and the moving platform 221, so that the relative position of the support member 223 and the moving platform 221 can be adjusted, so that the support member 223 can be adjusted according to the different sizes of the products to be tested to adjust the products to be tested to a horizontal state.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
