Its function is to efficiently transmit the power of the motor to the sunroof glass, while achieving smooth and reliable operation of the sunroof through precise motion constraints.

[0003] Currently, the production process requires the manufacture of multiple sets of tooling to simulate the installation points of the system under various conditions. The tooling cost is high, and the measurement process requires switching the product between different toolings, resulting in a long measurement time. In addition, due to the large number of toolings and the existence of tolerances at the positioning points of each tooling, the measurement results are significantly affected. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology that require the manufacture of multiple sets of tooling to simulate the installation points of the system in various states during the production process, resulting in high tooling costs. Furthermore, the measurement process requires switching between different toolings, which leads to a long measurement time. Additionally, due to the large number of toolings and the existence of tolerances at the positioning points of each tooling, the measurement results are significantly affected. Therefore, this utility model proposes a measuring tooling for automotive sunroof transmission systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A measuring fixture for an automotive sunroof transmission system includes a base plate. Two first supports and a second support are fixedly connected to the upper surface of the base plate. A guide rail is provided at the gap between the two first supports and the two second supports on the base plate. A sliding plate is slidably mounted on the rail wall of the guide rail. A first bracket, a partition, and a second bracket are fixedly connected to the upper surface of the sliding plate. A sliding mechanism is provided at the top of each of the two first supports, and a flipping mechanism is provided at the top of each of the two second supports. A first detection block is installed at the connection between the sliding mechanism and the flipping mechanism. A second detection block is located above the first detection block. A first connecting seat and a second connecting seat are provided at the top of the first and second connecting seats. Positioning plates are slidably mounted on the tops of the two positioning plates.

[0007] Preferably, multiple reference sleeves are provided around the corners of the base plate, and handles are fixedly connected to both sides of the base plate.

[0008] Preferably, the first detection block has a first detection pin inside, and the second detection block has a second detection pin inside.

[0009] Preferably, the top of the partition is provided with a pad, and the connection point of the two positioning plates is provided with a connecting pin.

[0010] Preferably, the top end of the second bracket is fixedly provided with a first positioning seat and a second positioning seat, the top ends of the first positioning seat and the second positioning seat are respectively provided with a first positioning rail and a second positioning rail, and the top ends of the first positioning rail and the second positioning rail are respectively provided with a first positioning block and a second positioning block.

[0011] Preferably, the side wall of the slide plate is provided with a plug-in pin, and the upper surface of the base plate located on one side of the guide rail is fixedly connected with a plurality of limiting blocks, and the interior of the plurality of limiting blocks is provided with limiting slots that match the plug-in pins.

[0012] Compared with the prior art, this utility model provides a measuring fixture for automotive sunroof transmission systems, which has the following advantages:

[0013] 1. The measuring fixture for the automotive sunroof transmission system uses a first detection block and a second detection block as the core detection carriers. They are connected to the top of the first support and the second support respectively through a sliding mechanism and a flipping mechanism. The sliding mechanism can slide horizontally along the first support, and the flipping mechanism can rotate around the second support.

[0014] 2.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A measuring fixture for an automotive sunroof transmission system includes a base plate 1. Two first supports 10 and two second supports 11 are fixedly connected to the upper surface of the base plate 1. A guide rail 4 is provided at the gap between the two first supports 10 and the two second supports 11 on the base plate 1. A slide plate 25 is slidably provided on the rail wall of the guide rail 4. A first bracket 24, a partition plate 18, and a second bracket 30 are fixedly connected to the upper surface of the slide plate 25. A sliding mechanism 3 is provided at the top of each of the two first supports 10. A flipping mechanism 5 is provided at the top of each of the two second supports 11. A first detection block 12 is installed at the connection between the sliding mechanism 3 and the flipping mechanism 5. A second detection block 13 is provided above the first detection block 12. A first connecting seat 20 and a second connecting seat 23 are provided at the top of the first connecting seat 20 and the second connecting seat 23. A positioning plate 21 is provided at the top of each of the two positioning plates 21. A positioning connecting block 19 is slidably provided at the top of each of the two positioning plates 21.

[0023] The top of the second bracket 30 is fixedly provided with a first positioning seat 16 and a second positioning seat 26. The top of the first positioning seat 16 and the second positioning seat 26 are respectively provided with a first positioning rail 15 and a second positioning rail 27. The top of the first positioning rail 15 and the second positioning rail 27 are respectively provided with a first positioning block 14 and a second positioning block 28.

[0024] The first detection block 12 has a first detection pin 8 inside, the second detection block 13 has a second detection pin 9 inside, the top of the partition 18 has a pad 17, and the connection point of the two positioning plates 21 is provided with a connecting pin 22.

[0025] The base plate 1 serves as the basic carrier of the tooling, providing stable support for the measuring components. Multiple reference sleeves 2 arranged around the corners of the base plate allow the base plate 1 to be installed in the designated position. The reference coordinates of the tooling itself can be calibrated using standard gauges to ensure the accuracy of subsequent measurement data.

[0026] The positioning system consists of multiple adjustable components used to fix the automotive sunroof drive system in a preset measurement posture, providing a stable reference for testing.

[0027] The guide rail 4 and the slide plate 25 on the base plate 1 form a sliding adjustment mechanism. The slide plate 25 can move freely along the guide rail 4 to adapt to the sunroof transmission system of different sizes. The first connecting seat 20 and the second connecting seat 23 at the top of the first bracket 24 support the positioning plate 21. The positioning connecting block 19 slidably set on the positioning plate 21 can be adjusted along the plate body to clamp the slide rail or connecting rod end of the transmission system. The relative position of the two positioning plates is fixed by the connecting pin 22 to ensure the stability of the lateral positioning of the transmission system.

[0028] The first positioning seat 16 and the second positioning seat 26 at the top of the second bracket 30 are respectively connected to the first positioning rail 15 and the second positioning rail 27. The first positioning block 14 or the second positioning block 28 on the first positioning rail 15 and the second positioning rail 27 can slide along the rail body to position key components such as gearboxes and motor mounting seats of the transmission system. The structural differences of different models of transmission systems can be adapted by adjusting the position of the positioning blocks.

[0029] The pad 17 at the top of the partition 18 is used to support the middle part of the transmission system, ensuring that it is in a preset horizontal or vertical position.

[0030] The detection system uses an adjustable detection mechanism to accurately measure the key parameters of the transmission system: the first detection block 12 and the second detection block 13 are the core detection carriers, which are connected to the top of the first support 10 and the second support 11 respectively through the sliding mechanism 3 and the flipping mechanism 5. The sliding mechanism 3 can slide horizontally along the first support 10, and the flipping mechanism 5 can rotate around the second support 11. The two work together to adjust the spatial position of the first detection block 12 so that it fits the test surface of the transmission system.

[0031] The first detection pin 8 in the first detection block 12 and the second detection pin 9 in the second detection block 13 are precision gauges used to detect the hole position accuracy of the transmission system: if the detection pin can be smoothly inserted into the hole to be tested, the diameter and position tolerance of the hole meet the requirements; if there is jamming, it indicates that the hole position is offset or the diameter is out of tolerance.

[0032] By adjusting the positions of the sliding mechanism 3 and the flipping mechanism 5, the relative positional relationship of the transmission system components can be measured: for example, the center distance of the gear can be measured by the distance between the first detection block 12 and the second detection block 13, and the straightness of the slide rail can be measured by the parallelism deviation between the detection block and the positioning block.

[0033] Using a standard gauge, the reference coordinates of the base plate 1 are calibrated through the reference sleeve 2 to ensure the accuracy of the fixture itself. The sunroof transmission system to be tested is placed in the fixture, and the key parts are clamped by the positioning connecting block 19, the first positioning block 14, and the second positioning block 28. The pad block 17 is adjusted to support the middle section to ensure that the transmission system is in the preset measurement posture.

[0034] Slide the slide plate 25 to the appropriate position, insert the plug pin 6 into the slot of the corresponding limit block 29 to fix the slide plate, and adjust the position of the first detection block 12 and the second detection block 13 through the sliding mechanism 3 and the flipping mechanism 5 so that the detection pins 8 and 9 are aligned with the hole or part to be tested. By the smoothness of the insertion of the detection pin and the fit gap between the detection block and the part, determine whether the dimensional accuracy and positional tolerance of the transmission system meet the standards, and record the measurement data.

[0035] like Figure 1-4 As shown, multiple reference sleeves 2 are arranged around the corner of the base plate 1, and handles 7 are fixedly connected to both sides of the base plate 1.

[0036] The slide plate 25 is provided with a plug-in pin 6 sliding on its side wall. The bottom plate 1 is fixedly connected to a plurality of limit blocks 29 on the upper surface of the guide rail 4. The interior of the plurality of limit blocks 29 is provided with limit slots that match the plug-in pin 6.

[0037] The handles 7 on both sides of the base plate facilitate the handling and movement of the tooling, adapting to different testing scenarios. The plug-in pins 6 on the side wall of the slide plate 25 cooperate with multiple limit blocks 29 on the base plate: when the plug-in pins 6 are inserted into the limit slots of the limit blocks 29, the position of the slide plate 25 is locked; when pulled out, it can be slidably adjusted to flexibly adapt to different measurement needs.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
