[0044] like Figure 3 and Figure 4 As shown, the measuring tool and the fixture are set to cooperate to obtain the theoretical value of the measuring tool reading when the door glass enters the sealing groove of the vehicle frame. = +w, where w is the set coefficient; then move the door glass 3 downward, snap the connecting slot 22 of the clamp onto the top of the door glass 3, lift the door glass 3 until it cannot be lifted further, use one end of the scale to press against the edge of the frame 8, and then read the scale reading on the surface of the base 1 close to the frame 8 to obtain the reading of the measuring tool 5 when the door glass 3 enters the frame 8 .calculate and The difference between ;Will Theoretical insertion length A comparison is made to determine whether the airtightness and NVH performance of the entire vehicle after the door glass 3 is closed meets the design requirements, and accurate debugging is performed on the door glass 3 that does not meet the requirements.

[0045] From the above description, it can be known that the fixture provided by the present application has a simple structure and is easy to use. It can accurately measure the amount of door glass 3 entering the groove without damaging the vehicle, which is convenient for judging whether the installation of door glass 3 meets the design requirements. By obtaining the actual amount of entry into the groove, the door glass 3 that does not meet the requirements can be accurately debugged to make it meet the design requirements, thereby ensuring the consistency of the sealing and NVH performance of the entire vehicle.

[0046] Specifically, Figure 5 and Figure 6 As shown, in a specific example provided by the present application, the measuring tool accommodating portion 11 includes a placement groove 12 extending along the Z direction and penetrating the base 1 . The clamping part 2 includes a clamping sleeve 21 connected to the base 1, and the clamping sleeve 21 has a connecting clamping groove 22 matched with the top of the door glass 3. The clamping sleeve 21 includes a connecting part 211 and a transition part 212.

The top of the arc-shaped plate is an arc-shaped surface to simulate the top of the door glass 3. The transition part 212 includes two parallel transition plates and each transition plate is smoothly connected to the corresponding end of the arc-shaped plate. A slideway 222 is formed between the two transition plates to facilitate the sliding sleeve 21 on the top of the door glass 3. It should be noted that the slideway 222 is connected to the arc-shaped clamping groove 221 to form a connecting clamping groove 22.

[0047] Embodiment 2

[0048] When different types or models of measuring tools 5 are used, since the thickness of different types or models of measuring tools 5 is different, the placement slot 12 in the first embodiment cannot be adapted, which affects the actual use. Figure 7 and Figure 8 As shown, on the basis of the first embodiment, the measuring tool accommodating portion 11 in this embodiment further includes a clamping mechanism, the clamping mechanism includes a clamping plate 61 and an adjusting mechanism, the clamping plate 61 is slidably installed in the placement groove 12, and the adjusting mechanism is installed on the base 1, and is used to drive the clamping plate 61 to move in the placement groove 12 along the X direction, the X direction and the Z direction are two directions perpendicular to each other, and in some embodiments, the X direction and the Z direction can be consistent with the directions in the actual vehicle, that is, the X direction is the length direction of the car, and the Z direction is the height direction of the car. By adjusting the position of the clamping plate 61 in the placement groove 12 by the adjusting mechanism, it is possible to achieve clamping of measuring tools 5 of different thicknesses, facilitate accurate measurement using the measuring tool 5, and expand the application scope of the clamp of the present application.

[0049] like Fig.10 and Fig.11As shown in a specific example of the present application, at least one slide groove 121 extending along the X direction is provided at the bottom of the placement groove 12. When there are more than two slide grooves 121, these slide grooves are arranged in parallel at different heights in the placement groove 12. The clamping plate 61 is provided with a slide bar 611 that can be placed in the slide groove 121, and the clamping plate 61 is connected to the adjustment mechanism. Please refer to Figures 7 to 9 An adjustment hole 15 extending along the X direction is provided on the base 1. The adjustment mechanism includes a slide rod 64 and an adjustment rod 63. One end of the slide rod 64 is connected to the clamping plate 61, and the other end is slidably placed in the adjustment hole 15. The adjustment rod 63 that drives the slide rod 64 to move in the adjustment hole 15 is threadedly connected to the adjustment hole 15. In actual use, the clamping process is as follows: the adjusting rod 63 is turned clockwise to change the position of the adjusting rod 63 in the adjusting hole 15, which can drive the slide bar 64 to move in the adjusting hole 15, and then drive the clamping plate 61 to move in the placement groove 12, so as to achieve the clamping of the measuring tool 5; when the measuring fixture 5 needs to be moved, the adjusting rod 63 is turned counterclockwise to move the adjusting rod 63 away from the slide bar 64, and the operator pushes the clamping plate 61 through the measuring tool 5 to move the slide bar 64 in the adjusting hole 15, and at the same time, the clamping plate 61 releases the clamping of the measuring tool 5, and the measuring tool 5 can be moved at this time. When the measuring fixture 5 moves to the desired position, the above clamping process is repeated, so that the measuring fixture 5 is clamped. Specifically, in this embodiment, the number of the slide groove 121 and the number of the slide bar 611 are both two, and one slide bar 611 is correspondingly arranged in one slide groove 121. It is worth mentioning that an elastic plate 62 is provided on the clamping plate 61, and the elastic plate 62 and the slide rod 64 are located on two opposite sides of the clamping plate 61. In this embodiment, the elastic plate 62 is a silicone pad covering the clamping plate 61, which can ensure that the measuring tool 5 is clamped in actual use, while avoiding damage to the measuring tool 5 caused by the hard contact of the clamping plate 61. In other embodiments, the elastic plate 62 is made of flexible materials such as acrylic material or polyurethane material, which is not limited in this application.

[0050] like Figure 8 and Fig. 9 As shown, the end of the adjustment rod 63 away from the slide rod 64 is covered with an anti-slip gripping sleeve 631. Specifically, the gripping sleeve is made of silicone material, and the gripping sleeve made of silicone material increases the friction of the user's twisting, which is convenient for the operator to operate. In other embodiments, elastic protrusions are evenly provided on the gripping sleeve, and the protrusions increase the friction during operation. This application does not limit this, and the specific structure that can increase the friction between the operator and the adjustment rod 63 is within the protection scope of this application.

[0051] Embodiment 3

[0052] The difference between this embodiment and the second embodiment is that, see Figures 14 to 16In this embodiment, at least one group of movable grooves 122 and limiting grooves 123 connected to the movable grooves 122 are provided at the bottom of the placement groove 12 along the X direction. The limiting grooves 123 are located in the base 1, and the cross-sectional area of ​​the limiting grooves 123 is larger than the cross-sectional area of ​​the movable grooves 122. A clamping block 612 is provided on the clamping plate 61. The clamping block 612 includes a movable block 613 located in the movable groove 122 and a limiting block 614 located in the limiting groove 123. The limiting groove 123 forms a T-shaped structure with the movable groove 122. During the movement of the clamping plate 61, the movable block 613 moves in the movable groove 122, and the limiting block 614 moves in the limiting groove 123. In this embodiment, the cooperation between the clamping block 61 and the placement groove 12 enables the clamping plate 61 to be independently and stably located in the placement groove 12. See Fig.12 and Fig.13 , a threaded hole is provided on the base 1, and the adjustment mechanism includes an adjustment column 7, and the adjustment column 7 is threadedly connected to the threaded hole. It should be noted that the adjustment column 7 is not connected to the clamping plate 61. In actual use, the adjustment column 7 on the outside of the base 1 is screwed clockwise, and the adjustment column 7 pushes the clamping plate 61 to clamp the measuring tool 5, so as to accurately obtain the actual extension length of the door glass 3 into the vehicle frame sealing groove 4; when the measuring tool needs to be adjusted or removed, the adjustment column 7 is screwed counterclockwise so that the end of the adjustment column 7 that abuts against the clamping plate 61 gradually moves away from the clamping plate 61, and the clamping plate 61 can slide in the placement groove. At this time, the measuring tool 5 can be moved or removed. When the measuring tool 5 is moved to the required position, the adjustment column 7 is screwed clockwise so that the end of the adjustment column 7 pushes the clamping plate 61 close to the measuring tool 5 to clamp the measuring tool 5.

[0053] The measuring tool accommodating parts 11 in the first embodiment, the second embodiment and the third embodiment are all placement grooves 12, and the measuring tools 5 are all scales, such as Fig.17 As shown, in other embodiments, the measuring tool 5 may also be a distance sensor. When the measuring tool 5 is a distance sensor, the measuring tool accommodating portion 11 is a mounting hole 13 that passes through the base 1 along the Z direction, and the distance sensor is disposed in the mounting hole 13. Fig.18 As shown, in another embodiment, the measuring tool 5 may also be a cylindrical telescopic ruler. When the measuring tool 5 is a cylindrical telescopic ruler, the measuring tool accommodating portion 11 is a placement hole 14 that penetrates the base 1 along the Z direction, and the cylindrical telescopic ruler is installed in the placement hole 14. Therefore, the present application does not limit the specific structure of the measuring tool accommodating portion 11, and the specific structure of the measuring tool accommodating portion 11 that is adapted to the measuring tool 5 is set.

[0054] See also Figure 1 A sealing strip 41 is provided in the vehicle frame sealing groove 4. When the door glass 3 does not enter the vehicle frame 8, the sealing strip 41 is in an initial state and is not squeezed by the door glass 3. Figure 2When the door glass 3 enters the sealing groove 4 of the vehicle frame, the door glass 3 extends a certain length to squeeze the sealing strip 41. In order to ensure the sealing and NVH performance of the entire vehicle, the actual length of the door glass 3 entering the sealing groove 4 of the vehicle frame needs to meet the design requirements. When measuring, refer to Figure 3 The fixture of the utility model is sleeved on the top of the door glass 3, and the door glass 3 squeezes the sealing strip 41, and then the measuring tool 5 is used to measure the amount of the frameless door glass entering the groove.

It should be noted that the distance between the edge of the frame 8 and the edge of the sealing strip 41 is a fixed value c, so in this embodiment, the length L between the clamp measurement base surface and the bottom of the connection slot is = + -c, where = +w, so L=2 +wc, where The value of c is a fixed value, and thus the value of L is determined by setting the value of w. Specifically, in this embodiment, w=0, = , L = + -c=2 -c.

[0059] Step S220: Obtaining the reading of the measuring tool 5 when the door glass 3 does not enter the vehicle frame sealing groove 4 ; See Figure 6 , by cooperating with the measuring tool and the fixture, the reading of the measuring tool is obtained when the door glass enters the sealing groove of the car frame include:

[0060] Step S221: moving the door glass downward;

[0061] Step S222: buckle the connecting slot of the clamp onto the top of the door glass;

[0062] Step S223: lifting the door glass until it cannot be lifted further;

[0063] Step S224: Use the measuring tool installed in the fixture to measure the reading of the measuring tool when the door glass enters the sealing groove of the vehicle frame. Specifically, first move the door glass 3 downward, then buckle the connecting slot 22 of the clamp on the top of the door glass 3, lift the door glass 3 until it cannot be lifted further, use one end of the scale to press against the edge of the frame 8, and then read the scale reading on the surface of the base 1 close to the frame 8 to obtain the reading of the measuring tool 5 when the door glass 3 enters the frame 8 .

[0064] Step S230: Calculation and The difference between In this embodiment, since the value of L is fixed, L= + -c, in step S210, L= + -c, so + -c= + -c, and then +( ).

[0065] Step S300: determine whether the difference δ is within the allowable error range k.

[0066] Step S400: If the difference δ is within the allowable error range k, the door glass 3 meets the installation requirements, and the door glass 3 is adjusted to meet the installation requirements.

[0067] Step S500: If the difference δ is not within the allowable error range k, the door glass is adjusted until it meets the installation requirements, specifically including:

[0068] Step S510: Determine the difference δ and the allowable error range k;

[0069] Step S521: if the difference δ is less than the allowable error range k, the absolute value of the difference between the middle value of the allowable error range k and the difference δ is taken as the correction value m;

[0070] Step S522: Move the door glass 3 located at the door upward by a correction value m so that the difference δ is within the allowable error range k, and the adjustment of the door glass 3 is completed.

[0071] Step S531: if the difference δ is greater than the allowable error range k, the absolute value of the difference between the middle value of the allowable error range k and the difference δ is taken as the correction value m;

[0072] Step S532: Move the door glass 3 downward by a correction value m so that the door glass 3 meets the installation requirements, and the adjustment of the door glass 3 is completed.

In this embodiment, the preferred interval endpoint value of the correction error range n is half of the corresponding endpoint value of the allowable error range k interval. That is, the range of n is -0.5~0.5mm. It should be noted that in the process of adjusting the door glass 3 to meet the installation requirements, there are deviations in the reading of the indications and debugging errors that occur during the installation process. In order to ensure that the debugging can be successful once, the present application selects the absolute value of the difference between the middle value of the allowable difference range k and the difference δ as the correction value m, thereby ensuring that the deviation within the above correction error range can also meet the installation requirements and improve the adjustment efficiency of the door glass 3.
