[0002] In the field of automotive manufacturing technology, it is often necessary to test and inspect various automotive components to check their dimensional accuracy and performance in order to study the failure mechanisms and analyze the causes of failure. Automotive fixtures are inspection tools with actual automotive part interface dimensions. They are used to check whether the dimensions of actual automotive parts meet standards. Some automotive parts have complex curved surfaces and require high installation precision. Therefore, the relevant interface dimensions on the fixtures used for inspecting automotive parts need to have high accuracy to ensure that the dimensions of the actual automotive parts installed on the fixture are up to standard. Because the fixtures are complex in shape and require precision control at many points, they need to be accurately positioned to inspect multiple points with dimensional accuracy requirements. However, existing fixture technologies cannot complete the inspection of multiple points in a single clamping and positioning operation. Utility Model Content

[0036] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0037] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0038] like Figures 1 to 4As shown, this utility model provides a multi-point testing device for a part fixture 2, including a mounting platform 1. The mounting platform 1 is provided with a positioning support frame 3 for positioning and mounting the part fixture 2. Multiple clamping assemblies 4 for clamping the part fixture 2 are provided around the positioning support frame 3. Multiple flipping testing arms 5 are also provided around the positioning support frame 3. At least one testing head 6 for testing the dimensional accuracy of the part fixture 2 is connected to each flipping testing arm 5. Each testing head 6 is used to test the dimensional accuracy of different testing positions on the part fixture 2.

[0039] When using the multi-point detection device of this invention to detect part fixture 2, after the positioning and clamping are completed, the accuracy of multiple detection positions on part fixture 2 can be detected simultaneously. This detection method is not only efficient, but also does not introduce errors due to changes in the positioning reference, thus achieving high detection accuracy.

[0040] In the multi-point inspection device for part fixture 2 of this utility model, the positioning support frame 3 for positioning part fixture 2, the clamping assembly 4 for clamping part fixture 2, and the flipping inspection arm 5 for inspecting part fixture 2 are integrated onto the mounting platform 1. The relative positions of the positioning support frame 3 and the flipping inspection arm 5 on the mounting platform 1 are accurately positioned, and the inspection head 6 is accurately positioned on the flipping inspection arm 5. In this way, there is an accurate positioning benchmark for clamping, positioning, and inspection of part fixture 2. Therefore, the inspection head 6 has high accuracy in inspecting part fixture 2.

[0041] To ensure accurate positioning of the part inspection fixture 2 on the positioning support frame 3, as a preferred embodiment, such as... Figure 2 As shown, the positioning support frame 3 is provided with multiple positioning block 7 interfaces (not shown in the figure). Positioning blocks 7 are detachably installed on the positioning block 7 interfaces. The positioning blocks 7 are used for positioning and connecting the part fixture 2. The positioning blocks 7 can be positioned and connected to the positioning support frame 3 using a one-sided, two-pin positioning method. This positioning method is simple and accurate. Figure 1 and Figure 2 As shown, a positioning pin 17 is provided in the middle part of the positioning support frame 3. The positioning pin 17 passes through the part inspection tool 2 and is inserted into the positioning hole of the positioning block 7 on the positioning support frame 3.

[0042] When inspecting the part fixture 2, the flip-up inspection arm 5 flips up until the inspection head 6 is aligned with the inspection position on the part fixture 2. When it is necessary to install or remove the part fixture 2, the flip-up inspection arm 5 is opened outward so that the flip-up inspection arm 5 and the inspection head 6 are moved away from the part fixture 2 to facilitate installation or removal operations. As a preferred embodiment, such as... Figure 3 and Figure 4 As shown, the flip detection arm 5 is connected to the mounting frame 9 via a rotating shaft 8, and the mounting frame 9 is provided with a limiting block 10, as shown. Figure 4 As shown, the flipping detection arm 5 can be flipped to a position against the limiting block 10 when not performing detection operations; as Figure 3 As shown, the mounting bracket 9 is also provided with a locking screw hole 11. When the flip-up detection arm 5 is rotated to the position for detection, a locking bolt 12 is passed through the flip-up detection arm 5 and screwed into the locking screw hole 11 to lock the flip-up detection arm 5 onto the mounting bracket 9. For a preferred embodiment, please refer to... Figure 1 and Figure 2 The mounting frame 9 is a vertically arranged channel steel. The flip detection arm 5 is connected to the two side walls of the channel steel through the rotating shaft 8. The locking screw hole 11 is set on the bottom of the channel steel. In order to facilitate the tightening of the locking bolt 12, a handle 13 is also provided on the head of the locking bolt 12.

[0043] To ensure accurate positioning of the detection head 6 on the flip detection arm 5, such as Figure 3 and Figure 4 As shown, a positioning detection frame 14 is connected to the flipping detection arm 5, and the detection head 6 is positioned and connected to the positioning detection frame 14. The detection head 6 has a retractable pressure detection probe 15, which is driven by a cylinder to extend and retract. When no detection is needed, the cylinder drives the pressure detection probe 15 to retract, preventing the pressure detection probe 15 from being damaged by accidental collisions. When detection is needed, the cylinder extends the pressure detection probe 15 to a set position to contact the part inspection fixture 2. If the pressure value exceeds the set range, it indicates that the error at the detection position is out of tolerance. For example, if the set acceptable pressure range is P1 to P2, if the pressure value detected by the pressure detection probe 15 is less than P1 (P1 is generally set to 0), the detection position is recessed or lacks material, resulting in insufficient size. If the pressure value is greater than P2, the detection position is protruding, resulting in excessive size.

[0044] To efficiently and conveniently detect errors in the part fixture 2, in a preferred embodiment, the detection head 6 is communicatively connected to a host computer. The host computer receives the detection signals transmitted by the detection head 6 and displays them on a monitor. This allows for a clear understanding of the error at each detection position. For ease of operation, in a preferred embodiment, the mounting platform 1 is equipped with a control button for extending and retracting the pressure probe 15. After the part fixture 2 is installed and positioned, the flip detection arm 5 is rotated to the detection position, and pressing the button causes the cylinder to drive the pressure probe to extend for detection. To promptly identify non-conforming dimensions, the mounting platform 1 is also equipped with an alarm light. When the data detected by the pressure probe 15 exceeds the error range, the alarm light displays an alarm signal. This allows the inspector to clearly see any non-conforming dimensions and prevents them from missing error data due to operator fatigue.

[0045] To facilitate zeroing of the part gauge 2, a zeroing block 16 is detachably connected to the position on the part gauge 2 where the detection head 6 needs to be detected. After the high-precision part gauge 2 with the zeroing block 16 is positioned and installed on the positioning support frame 3, the detection device is zeroed using the zeroing block 16, so that the pressure detection probe 15 contacts the zeroing block 16 on the part gauge 2, and the initial pressure of each detection head 6 is set to zero for zeroing. Then, the part gauge 2 used for zeroing is removed and the part gauge 2 to be detected is installed, so that the detection device can repeatedly detect the part gauge 2.

[0046] Based on the technical solutions of the above embodiments, the multi-point detection part fixture detection device of this utility model can simultaneously detect the accuracy of multiple detection positions on the part fixture, with high detection efficiency and high detection accuracy.

[0047] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
