[0042] See Figure 5 as shown Figure 5 The use process of the measuring component in the prior art is shown. In the prior art, the measuring component 903 (such as a clearance snap gauge, a steel ruler, etc.) can be understood to measure the measured part 904 through point contact. This process often causes measurement data errors due to human factors. For example, see Figure 6 as shown Figure 6This shows the generation process of the measurement error of the measurement components in the prior art. The ideal situation in the figure is shown by the pair of measurement components 903 in the middle of the figure. However, in actual situations, due to limitations such as measurement methods and working environments, the measurement components 903 may Figure 6 be in the situation shown by the pair of measurement components 903 on the right side in the figure, thus generating obvious measurement errors.
[0043] In order to measure the gap of the automotive sheet metal more accurately and stably, especially the inner gap size of the four doors, one embodiment of the present application provides a measuring device for the gap of the automotive sheet metal.
[0044] Referring to Figures 1 to 4 the embodiment shown, the measuring device for the gap of the automotive sheet metal includes:
[0045] A scale 100, having a length direction and indicating scales 101 arranged along the length direction;
[0046] A first measuring part 200, fixed to one end of the scale 100 and having a first measuring plane 201 perpendicular to the length direction;
[0047] A moving seat 300, slidably mounted on the scale 100;
[0048] A second measuring part 400, fixed to the moving seat 300 and having a second measuring plane 401 arranged opposite to the first measuring plane 201;
[0049] A locking member 500, acting between the scale 100 and the moving seat 300 to maintain their relative positions.
[0050] Through the first measuring plane 201 of the first measuring part 200 and the second measuring plane 401 of the second measuring part 400, the cooperation mode between the measuring device and the measured part can be effectively restricted, ensuring that the measuring device is stably and properly matched with the measured part according to the preset situation, thereby overcoming the errors caused by measurement methods and measurement angles. Even if a positioning error occurs, the measuring device in the present application can automatically eliminate the above-mentioned positioning error through the fitting of the first measuring plane 201, the second measuring plane 401 and the measured part, thereby improving the measurement accuracy. On this basis, the sliding fit between the moving seat 300 and the scale 100 can obtain accurate readings, thereby realizing stable and accurate measurement of the gap of the automotive sheet metal.
[0051] The measurement of the measuring device mainly depends on the cooperation between the first measurement plane 201 and the second measurement plane 401 and the measured part respectively. In the embodiment shown in the figure, the first measurement plane 201 and the second measurement plane 401 are arranged in parallel. On the sides of the first measurement part 200 and the second measurement part 400 away from the scale 100, there are guiding inclined surfaces 202 respectively. Each guiding inclined surface 202 can guide the corresponding first measurement part 200 or second measurement part 400 into the preset measurement position, improving the use experience. Further, the guiding inclined surfaces 202 of the first measurement part 200 and the second measurement part 400 are arranged back to back, and the guiding inclined surfaces 202 of both gradually approach as they are away from the scale 100.
[0052] As shown in the accompanying drawings, the scale 100 and the first measurement part 200 in the figure are of an integral structure and are integrally L-shaped. The moving seat 300 is integrally cylindrical, and the second measurement part 400 is connected to the outer peripheral side wall of the cylindrical shape. The moving seat 300 and the second measurement part 400 are of an integral structure. The integration of each component can simplify the assembly of the measuring device and reduce the maintenance difficulty. Further, the scale 100 is plate-shaped and has a width direction and a thickness direction corresponding to the length direction. The first measurement part 200 and the second measurement part 400 extend along the thickness direction of the scale 100. In the figure, compared with the positions of the first measurement part 200 and the second measurement part 400, the indicating scale 101 of the scale 100 is located on the other side of the scale 100. This setting can achieve direct reading during the measurement process without taking out the measuring device. Compared with the prior art where the indicating scale is located on the side of the measured part, the indicating scale 101 arranged in the thickness direction of the scale 100 can meet the need for quick reading, especially in some parts where the surrounding space for measurement is relatively narrow. Correspondingly, multiple indicating scales 101 can be provided in multiple directions of the scale 100, such as the width direction, thickness direction, and height direction of the scale 100, to facilitate quick reading by the operator in each direction.
[0053] In the assembly of the measuring device, the moving seat 300 is provided with a guiding hole 301 and is slidably sleeved on the scale 100 through the guiding hole 301. The edge of the guiding hole 301 serves as the reading reference of the scale 100. The guiding hole 301 can achieve sliding fit by the mutual adaptation of its own size and the size of the scale 100, or a sliding fitting part can be installed in the guiding hole 301, and the scale 100 is slidably fitted in the guiding hole 301 through the sliding fitting part.
[0054] In terms of the detailed settings of the locking member 500, in one embodiment, the moving seat 300 is provided with an installation hole communicating with the guiding hole 301, and the locking member 500 is in threaded fit with the installation hole. Further, one end of the locking member 500 is a limiting section extending into the installation hole and abutting against the scale 100, and the other end is an operating end located outside the installation hole, and the operating end is provided with a handle. The limiting section can limit the relative movement of the scale 100 by pressing it. In one embodiment, the scale 100 is provided with positioning holes corresponding to preset dimensions, and the limiting section and the positioning holes cooperate with each other. The cooperation between the positioning holes and the limiting section of the locking member can quickly adjust the measuring device to a preset dimension, so as to quickly confirm the dimensions of multiple measured parts. In continuous production, this function will have positive significance.
[0055] In terms of the overall dimensions of the measuring device, along the width direction of the scale 100, the widths of the first measuring plane 201 and the second measuring plane 401 are 10 mm to 30 mm. Further, the width of the first measuring plane 201 is less than the width of the second measuring plane 401, where the width of the first measuring plane 201 is 10 to 20 mm, and the width of the second measuring plane 401 is 15 to 25 mm. In the figure, the width of the first measuring plane 201 is 12 to 15 mm, and the width of the second measuring plane 401 is 15 to 17 mm. The thickness direction of the scale 100 is the height direction of the first measuring part 200 and the second measuring part 400, where the height of the first measuring part 200 is 25 mm to 75 mm, and the height of the second measuring part 400 is 15 mm to 65 mm. In the figure, the height of the first measuring part 200 is 30 mm to 60 mm, and the height of the second measuring part 400 is 25 mm to 55 mm. It can be seen from the figure that the end of the first measuring part 200 is slightly longer than that of the second measuring part 400, that is, the guiding inclined surface 202 of the first measuring part 200 contacts the measured part earlier. The length of the scale 100 is 15 mm to 45 mm. In the figure, the length of the scale 100 is 25 mm to 35 mm. Each part of the measuring device is machined from aluminum alloy material.
[0056] During use, refer to Figure 4 , the measuring device in this application performs the following operations:
[0057] Release the locking member 500, thereby allowing the first measuring part 200 and the second measuring part 400 to move relative to each other, for example, realizing the mutual approach or separation of the two;
[0058] Move the measuring device to the part to be measured, and press the first measuring plane 201 and the second measuring plane 401 against the corresponding positions respectively; for example, after the first measuring plane 201 is attached to the matching surface 901 of the inner panel of the car door, drive the moving seat 300 to slide on the scale 100 to make the second measuring plane 401 fit with the rabbet edge 902. During the fitting process of the first measuring plane 201 and the second measuring plane 401, the measuring device is automatically adjusted to the accurate measuring position;
[0059] Read the value directly from the indicating scale 101 of the scale 100 or read the value from the indicating scale 101 of the scale 100 after locking the locking member 500 to obtain the measured inner clearance dimension.
[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are reflected in the same drawing, the drawing can be regarded as simultaneously disclosing the combination examples of the respective embodiments involved.
[0061] The above-mentioned embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
