Description

Technical Field

[0001] This utility model belongs to the field of applicable measuring tools technology for welding and assembly production lines in the automobile manufacturing industry, and specifically relates to a vehicle body matching degree measuring device. Background Technology

[0002] Currently, in the mass production of automobiles, the welding and assembly process requires assembly of parts from one workstation to the next according to a set production rhythm and process standards in order to improve labor productivity. During assembly, to facilitate worker operation, improve production rhythm, and ensure assembly quality, a body matching degree measuring device is needed for rapid data monitoring and self-inspection. In actual production, measuring each large batch of products individually using graduated measuring tools (such as vernier calipers, dial indicators, and triangular clearance gauges) is inefficient. Therefore, a measuring device suitable for large-scale matching degree measurement is needed. Utility Model Content

[0003] This utility model utilizes the welding and assembly process in the automotive manufacturing industry to provide a vehicle body matching degree measuring device that can effectively identify the body matching gap status under assembly line operation conditions in a short time. Its working part is manufactured according to the dimensions required by standard processes. The technical solution is as follows:

[0004] A vehicle body matching degree measuring device, see attachment. Figure 1 The main body is a hollow inner circle with six convex corner disc-shaped structures around the perimeter. Each convex corner contains two stepped detection surfaces: a first detection surface and a second detection surface, for a total of 12 detection surfaces. Each detection surface has the same shape, length, and width, but a different thickness, and can measure or calibrate 12 gaps of corresponding sizes. Two dimensions are also marked on the two detection surfaces at each corner.

[0005] The device also includes six grooves for easy insertion of a hanging rope and hanging; the hollow round hole in the middle makes it easy to grip and hold, and can also be slipped on the finger for easy carrying.

[0006] Furthermore, in order to accommodate the measurement and calibration of gap sizes of connecting parts with larger or smaller values, the device of this invention can be made larger or smaller by simply changing the thickness of the 12 detection surfaces of the device of this invention.

[0007] By manufacturing this utility model device with different measuring ranges and thicknesses, it is possible to detect and calibrate the gap dimensions of connecting parts of all sizes. This device can be manufactured using only 45# steel according to standard process drawings, making it both practical and cost-effective. It reduces rework time and resources caused by assembly errors, improving assembly time and efficiency. Furthermore, to protect the paint from scratches on the tested connecting parts, the device can be made of polyoxymethylene, nylon, or other special materials to meet specific needs.

Moreover, the materials are easy to obtain, the manufacturing process is simple, the manufacturing cost is low, and the durability is high. Detailed Implementation

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] See appendix Figure 2 The main body has a central inner circular hole 5 and a six-convex-corner disc-shaped structure around the perimeter. Each convex corner contains two stepped detection surfaces: a first detection surface 1 and a second detection surface 2, for a total of 12 detection surfaces. The thicknesses of the 12 detection surfaces are 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, and 6.0mm, respectively. Each detection surface has the same shape, length, and width, but a different thickness. It can measure or calibrate 12 corresponding gaps. At the same time, two dimensions are marked on the two detection surfaces at each corner, specifically 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, and 6.0mm, in millimeters. This makes it easy to see the thickness of each detection surface. For example, if you need to measure or calibrate the gap between two connecting parts that is 3.0mm, you can immediately find the detection surface marked 3.0mm, insert the 3.0mm detection surface into the gap between the connecting parts, and immediately determine whether the gap between the connecting parts is 3.0mm.

[0030] This vehicle body fit measurement device can measure gaps from 0.5 to 6 mm. Specifically, the measurements are 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, and 6.0 mm, all in millimeters. For example, 4.5 mm means the upper half of the feeler gauge is 4.5 mm thick, 5.0 mm means the lower half is 5 mm thick, and so on. This vehicle body fit measurement device can measure gaps of 0.5-6 mm, but the measuring range can be adjusted or expanded depending on the application. To expand the measurement range to 6.0mm-12mm, 12.0mm-16.0mm, or 16.0mm-22.0mm, simply change the material thickness of the outer and second detection surfaces of the measuring device to meet the corresponding measurement range requirements. Therefore, this vehicle body matching degree measuring device can theoretically meet the needs of measuring, comparing, and calibrating gaps of any size.

[0031] For example, if it is necessary to measure and calibrate the gap size between connecting parts between 0.08mm and 1mm, the thickness of the 12 detection surfaces can be made to be 0.08mm, 0.09mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm. At the same time, the markings on the 12 detection surfaces can be made to be 0.08mm, 0.09mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm.

[0032] For example, if it is necessary to measure and calibrate the gap between connecting parts between 6mm and 17mm, the thickness of the 12 detection surfaces can be made to be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, and 17mm. At the same time, the markings on the 12 detection surfaces can be made to be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, and 17mm.

[0033] When it is necessary to measure and calibrate the gap between connecting parts with a diameter between 10mm and 120mm, the thickness of the 12 detection surfaces can be made into 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, and 120mm. At the same time, the markings on the 12 detection surfaces can be made into 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, and 120mm.

[0034] See appendix Figure 1-5 During specific testing, each first detection surface 1 corresponds to a measurement value. When a first detection surface 1 is inserted into a gap in the object being tested and completely fills the gap, the value on that first detection surface is the gap value of the object being tested. Each second detection surface 2 corresponds to a measurement value. When a second detection surface 2 is inserted into a gap in the object being tested and completely fills the gap, the value on that second detection surface is the gap value of the object being tested. The measuring tool's handle 3 is convenient for gripping. The lanyard groove 4 is used to thread the lanyard through this groove, and the inner circular hole 5 facilitates hanging it on the object.

[0035] The measurement steps are as follows:

[0036] (a) Measuring the size of the gap

[0037] 1. First, estimate the size of the gap between the objects being measured;

[0038] 2. Insert the first detection surface 1 or the second detection surface 2, which corresponds to the estimated value, into the gap of the object being measured;

[0039] 3. If it cannot be inserted, replace the first detection surface 1 or the second detection surface 2, which is one size smaller than the estimated value, and insert it into the gap of the object being tested.

[0040] 4. If it still cannot be inserted, continue to replace the first side detection surface 1 or the second detection surface 2, which is one size smaller than the estimated value, and insert it into the gap of the object being tested until it can be inserted just right. At this time, the value on the vehicle body matching degree measuring device is the gap value of the object being tested.

[0041] 5. If there is still a gap after inserting it, replace the first detection surface 1 or the second detection surface 2, which is one size larger than the estimated value, and insert it into the gap of the object being tested.

[0042] 6. If there is still a gap after inserting, continue to replace the first detection surface 1 or the second detection surface 2, which is one size larger than the estimated value, and insert them into the gap of the object being tested until they fit perfectly. At this point, the value on the vehicle body matching degree measuring device is the gap value of the object being tested.

[0043] (ii) Compare and verify whether the size of the gap is up to standard.

[0044] 1. First, read the gap size value of the object being measured;

[0045] 2. Insert the first or second detection surface of the measuring device corresponding to the reading into the gap of the object being measured;

[0046] 3. If it cannot be inserted, the object being tested is unqualified;

[0047] 4. If there are still gaps after inserting the needle, the tested object is unqualified;

[0048] 5. If it fits perfectly, the gap size of the object being tested is acceptable.
