Description

A door cover edge thickness detection device Technical Field

[0001] This application relates to the field of measurement technology, specifically to a device for detecting the thickness of a door cover edge. Background Technology

[0002] Vehicle door hoods are assembled by using an edge-wrapping process to join the inner and outer panels together. The inner and outer panels are sheet metal parts. Edge wrapping refers to the method of connecting two sheet metal parts by wrapping the periphery of one part with the folded edge of the other part. Edge wrapping is a common process in traditional vehicle door hood manufacturing, with robot rolling or mold pressing accounting for a large proportion. However, manual edge wrapping is used during part trial production or small-batch production.

[0003] In actual vehicle production, some door hood edges are finished with a teardrop-shaped edging. This type of edging creates a teardrop-shaped curve on the edge of the hood, which is not only aesthetically pleasing but also adds a smooth, blunt feel, helping to reduce pedestrian injuries in traffic accidents. The effective compression area of ​​the teardrop-shaped edging is at the root of the outer panel trim, not at the crease. The thickness at the crease is greater than the thickness of the compressed trim area. Therefore, when using measuring tools like calipers, it is often difficult to accurately measure the thickness of the actual compressed edging area due to the obstruction at the crease. Summary of the Invention

[0004] This application provides a door cover edge thickness detection device, which is applicable to most edge types and measurement locations for measuring the thickness of door cover edges. In particular, it can also accurately monitor and measure the actual pressing part of teardrop-shaped edges.

[0005] In a first aspect, embodiments of this application provide a door cover edge thickness detection device, comprising: a measuring block having a first measuring arm at one end of its back side, the first measuring arm extending vertically outward from the back side and having a first measuring head at its end, and a marking line on the front side of the measuring block; a base block slidably fitted onto the measuring block, the base block having a slot penetrating both ends, and the marking line of the measuring block being exposed in the slot, the slot having a scale line on at least one side, a second measuring arm extending vertically outward from the back side of the base block, and a second measuring head at the end of the second measuring arm opposite to the first measuring head; when the two measuring heads contact each other, a receiving space is formed between the two measuring arms to accommodate the corner of the door cover edge, and the marking line corresponds to the initial scale value of the scale line.

[0006] In some embodiments, the base block has a threaded through hole on its side, and a locking bolt for fixing the position of the measuring block is provided in the threaded through hole.

[0007] In some embodiments, the slot is provided along the path of movement of the base block.

[0008] In some embodiments, both measuring heads are hemispherical structures.

[0009] In some embodiments, the base block has a through groove communicating with the slot, the measuring block is disposed in the through groove, and the length of the measuring block is greater than the length of the base block.

[0010] In some embodiments, the first measuring arm is located on the center line of the back of the base block, and the second measuring arm is located on the center line of the back of the measuring block.

[0011] In some embodiments, the measuring block has a protrusion on its front side, the protrusion is located in the slot, and the marking is disposed on the front side of the protrusion.

[0012] In some embodiments, the axial length of the bump is less than the length of the slot.

[0013] In some embodiments, the front surface of the protrusion is on the same plane as the front surface of the base block.

[0014] In some embodiments, the bump and the measuring block are an integral structure.

[0015] The beneficial effects of the technical solutions provided in this application include:

[0016] By slidably fitting the base block onto the measuring block, the distance between the first and second measuring heads can be flexibly adjusted, making it suitable for measuring the thickness of most different sizes of door cover edging. By setting markings on the front of the measuring block and opening a slot through both ends on the base block, the markings of the measuring block are exposed in the slot, and a scale line is provided on at least one side of the slot. The slot places the markings and scale lines on the same visual plane, allowing users to directly read the value by observing the position of the markings on the scale lines, avoiding reading errors caused by oblique viewing or blurred scales. This is especially suitable for rapid measurement in bright or dim environments.

[0017] When the two measuring heads come into contact, it indicates that the door cover edge thickness measurement has not yet begun. At this time, a receiving space is formed between the two measuring arms to accommodate the corner of the door cover edge. The initial scale value of the mark corresponds to the scale line, and the door cover edge thickness detection device is calibrated. During measurement, the measuring block and the base block slide relative to each other. The corner of the door cover edge is located within the receiving space and no longer affects the actual pressing part of the inner and outer panels of the door cover edge held by the two measuring heads. The scale value of the mark on the scale line is read, thereby measuring the true door cover edge thickness. With this application, compared with measuring tools such as vernier calipers, the thickness of the actual pressing part of the teardrop-shaped edge can be directly measured, and the measurement is not limited by the edge type. At the same time, this application has a simple structure, is easy to use, and has a lower manufacturing cost than electronic edge measuring instruments. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0026] This application provides a door cover edge thickness detection device, which is applicable to most edge types and measurement locations when measuring the thickness of door cover edges. In particular, it can also accurately monitor and measure the actual pressing part of teardrop-shaped edges.

[0027] Referring to Figures 1 and 2, Figure 1 is a front perspective view of the door cover edge thickness detection device in an embodiment of this application; Figure 2 is a rear perspective view of the door cover edge thickness detection device in an embodiment of this application. As shown in Figures 1 and 2, in one embodiment, the door cover edge thickness detection device includes a measuring block 1 and a base block 2. The base block 2 is slidably fitted onto the measuring block 1, and relative sliding can occur between the two. A first measuring arm 11 is provided at the rear end of the measuring block 1, extending vertically outward from the rear end of the measuring block 1, and a first measuring head 12 is provided at the end of the first measuring arm 11. Here, as can be seen from Figure 2, the first measuring arm 11 has a certain length, and the end of the first measuring arm 11 is the end of the first measuring arm 11 away from the measuring block 1. The first measuring head 12 can be a hemispherical structure, but in fact, in addition to the hemispherical structure shown in Figure 1, the first measuring head 12 can also be a "bullet head" structure.

[0028] The measuring block 1 has a straight line 13 on its front side. The base block 2 has a slot 21 that runs through both ends, exposing the measuring block 1's line 13 within the slot 21. This shows that the slot 21 is located on the front side of the base block 2, and its purpose is to facilitate direct observation of the position of the line 13. At least one side of the slot 21 has a scale line 22. When the measuring block 1 slides relative to the base block 2, the actual displacement of the line 13 (observed from the slot 21) can be read using the scale line 22.

[0029] A second measuring arm 23 extends vertically outward from the back of the base block 2. At the end of the second measuring arm 23 is a second measuring head 24 opposite to the first measuring head 12. As can be seen in Figure 2, the second measuring arm 23 also has a certain length, slightly longer than the first measuring arm 11. The end of the second measuring arm 23 is the end furthest from the base block 2. The second measuring head 24 can be a hemispherical structure or a "bullet head" structure.

[0030] When the two measuring heads come into contact, a receiving space is formed between the two measuring arms to accommodate the corner of the door cover edge, and the initial scale value of the mark 13 corresponds to that of the scale line 22. This can be understood as the initial state when the two measuring heads are in contact. During measurement, the measuring block 1 and the base block 2 slide relative to each other, and the two measuring heads no longer come into contact. The receiving space is just enough to accommodate the corner of the door cover edge, so that one measuring head contacts the outer panel of the door cover edge, and the other measuring head contacts the inner panel of the door cover edge. By reading the scale value of the scale line 22 corresponding to the mark 13, the actual pressing position of the teardrop-shaped edge can be accurately calculated.

[0031] In this embodiment, by slidably fitting the base block 2 onto the measuring block 1, the distance between the first measuring head 12 and the second measuring head 24 can be flexibly adjusted, thus making it suitable for measuring the thickness of the edging of most different specifications of door covers. By setting a mark 13 on the front of the measuring block 1 and opening a slot 21 through both ends on the base block 2, the mark 13 of the measuring block 1 is exposed in the slot 21, and a scale line 22 is provided on at least one side of the slot 21. The slot 21 places the mark 13 and the scale line 22 on the same visual plane, and the user can directly read the value of the mark 13 at the position of the scale line 22, avoiding reading errors caused by oblique viewing or blurred scale, which is especially suitable for rapid measurement in strong light or dim environments.

[0032] When the two measuring heads come into contact, it indicates that the door cover edge thickness measurement has not yet started. At this time, a receiving space is formed between the two measuring arms to accommodate the corner of the door cover edge. The initial scale value of the mark 13 corresponds to the scale line 22, and the calibration of the door cover edge thickness detection device is complete. During measurement, the measuring block 1 and the base block 2 slide relative to each other. The corner of the door cover edge is located within the receiving space and no longer affects the actual pressing position of the inner and outer panels of the door cover edge held by the two measuring heads. The scale value of the mark 13 on the scale line 22 is read, thereby measuring the true door cover edge thickness.

[0033] Furthermore, in one embodiment, as shown in Figure 1, a threaded through hole is provided on the side of the base block 2, and a locking bolt 3 for fixing the position of the measuring block 1 is provided in the threaded through hole. In this embodiment, through the above technical solution, when the base block 2 slides along the measuring block 1 (or the measuring block 1 slides along the base block 2) to the target position, tightening the locking bolt 3 can rigidly fix the two through the thread friction, avoiding positional deviation caused by hand force, workpiece collision or vibration during the measurement process. For example, when measuring the thickness of the actual pressed part of the door cover edge, if the base block 2 accidentally slides after the two measuring heads are clamped, the scale reading will be directly distorted, while the locking bolt 3 can ensure "adjustment and locking", so that the reading corresponds 100% to the actual size.

[0034] Furthermore, in one embodiment, as shown in Figure 1, the slot 21 is set along the path of movement of the base block 2. In this embodiment, the path of movement of the base block 2 is the axial direction of the measuring block 1. Through the above technical solution, the mark 13 of the measuring block 1 and the scale line 22 of the base block 2 form a "coaxial visible channel" within the slot 21. When the operator looks at the slot 21 at eye level, the alignment interface of the mark 13 and the scale line 22 is on the same optical axis, avoiding parallax errors caused by viewing angle tilt.

[0035] Furthermore, in one embodiment, as shown in Figure 2, both measuring heads are hemispherical structures. In this embodiment, the top of the hemispherical structure is an arc surface. When measuring the thickness of the door cover edge, the two measuring heads can accurately fit with the actual pressing parts of the inner and outer panels of the door cover at a "point" or a "small arc surface," avoiding measurement errors caused by angular deviations when in planar contact. This is especially suitable for precise positioning of complex contours.

[0036] Furthermore, in one embodiment, as shown in FIG1, the base block 2 is provided with a through groove communicating with the slot 21, the measuring block 1 is disposed in the through groove, and the length of the measuring block 1 is greater than the length of the base block 2. In this embodiment, the through groove allows the measuring block 1 and the base block 2 to slide freely, and the portions of the measuring block 1 extending out of the base block 2 at both ends also provide a buffer space for the measuring block 1 to slide on the base block 2 (and the base block 2 to slide on the measuring block 1).

[0037] Furthermore, in one embodiment, as shown in Figure 2, the first measuring arm 11 is located on the center line of the back of the base block 2, and the second measuring arm 23 is located on the center line of the back of the measuring block 1. In this embodiment, through the above technical solution, the two measuring arms are located on the center lines of the back of the base block 2 and the measuring block 1 respectively, ensuring that the axes of the measuring heads are strictly collinear and perpendicular to the actual pressing part of the door cover edge.

[0038] Furthermore, in one embodiment, as shown in Figure 1, the front of the measuring block 1 is provided with a protrusion 14, which is located within the slot 21, and a marking line 13 is provided on the front of the protrusion 14. In this embodiment, the protrusion 14 is embedded in the slot 21 of the base block 2 to form a lateral limiting structure, so that when the measuring block 1 slides, the two measuring heads are always perpendicular to the surface of the actual pressing part of the edge; in addition, the marking line 13 is provided on the front of the protrusion 14 (parallel to the measurement direction), which can be read directly by the operator.

[0039] Furthermore, in one embodiment, as shown in FIG1, the axial length of the protrusion 14 is less than the length of the slot 21. In this embodiment, since there is only one marking line 13 on the front side of the protrusion 14, setting the axial length of the protrusion 14 to be less than the length of the slot 21 can greatly save materials while ensuring that the operator can read it directly.

[0040] Furthermore, in one embodiment, as shown in FIG1, the front surface of the protrusion 14 and the front surface of the base block 2 are on the same plane. In this embodiment, through the above technical solution, the marking line 13 (set on the front surface of the protrusion 14) and the reference plane of the base block 2 are on the same optical focal plane, which is convenient for the operator to observe.

[0041] Furthermore, in one embodiment, the protrusion 14 and the measuring block 1 are an integral structure. In this embodiment, the above technical solution ensures the relative positional accuracy between the protrusion 14 and the measuring block 1, thus ensuring the reliability of the measured values.

[0042] In other embodiments, the grip portion of the base block 2 is treated with an anti-slip coating for ease of use by the operator. The outer surfaces of the base block 2 and the measuring block 1 are rounded to prevent scratches to the operator.
