Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a color-separation tooling for the side wall of a rail vehicle body. Background Technology

[0002] The sidewall paint of rail vehicle bodies often features one or more color stripes. When the door supplier delivers all the color stripe paint, the sidewall stripe and the door stripe are painted separately. After the door is installed and adjusted, the sidewall stripe needs to be aligned with the door stripe. Therefore, the accuracy of the dimensions of the stripes requiring alignment is crucial. Even without considering the alignment issue between the door and body stripes, the accurate consistency of the color stripe lines across the same vehicle and different vehicles is also important.

[0003] The vehicle body is a three-dimensional structure with many curved and sloping surfaces. The design drawings are two-dimensional perspective views. The dimensions of the perspective view cannot be directly measured on the vehicle body. The main measuring tool on the production site is a steel tape measure, which can only measure the distance from point to point along the surface of the vehicle body.

[0004] The outer contour line of the side wall of the vehicle body section is composed of one or more line segments, including vertical line segments, oblique line segments, and arcs. The color strip line is located in the middle. To accurately measure the size of the color strip, one should measure the sum of the sizes of one or more line segments, including vertical line segments, oblique line segments, and arcs, on the outer contour line of the side wall. In order to measure the size of the color strip with a steel tape measure, the perspective view size is often converted into the contour line size.

[0005] Because steel measuring tapes have poor flexibility, they cannot fit snugly along the side wall of the vehicle body where there are changes in curvature and slope, resulting in deviations from the line segments that should be measured, and making it impossible to guarantee the accuracy of color separation dimensions.

[0006] Different OEMs use different positioning benchmarks and measurement methods for color strip dimensions. Commonly used positioning benchmarks include vehicle body structures such as chassis side beams and windows. Some manufacturers also use a specific color strip line as the positioning benchmark and then measure the dimensions of other color strip lines.

[0007] The structure along the top and bottom edges of the window is discontinuous. The color strips without window positions cannot be positioned using the structure along the top and bottom edges of the window. They can only be positioned by visually pulling the color-separated tape, which involves a lot of uncertainty and ultimately leads to deviations in the size of the color strips.

[0008] Therefore, there is an urgent need to provide a color-separation tooling for the side walls of rail vehicle bodies, which improves the accuracy of color separation dimensions compared to existing technologies. Utility Model Content

[0009] This utility model solves the technical problems existing in the prior art and provides a color-separation tooling for the side wall of a rail vehicle body.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A color-separation fixture for the side wall of a rail vehicle includes a plate, a positioning plate, and multiple color-separation rulers. The positioning plate is fixedly connected to the lower end of the side wall of the plate. Multiple color-separation rulers are fixedly connected to the side wall of the plate where the positioning plate is located. Each color-separation ruler has a color-separation point at the lower end of the side wall that contacts the side wall of the vehicle. The color-separation point is used to assist in marking contour points on the side wall of the vehicle. Different color-separation points are used to mark contour points of different contours.

[0011] Furthermore, the plurality of color separation rulers include a first color separation ruler, a second color separation ruler, a third color separation ruler, and a fourth color separation ruler, which are arranged sequentially from the end closest to the positioning plate to the end furthest from the positioning plate.

[0012] Furthermore, the side wall of the first color separation ruler away from the plate is set as the first bonding wall, which is bonded to the side wall of the vehicle, and the lower end of the first bonding wall is set as the first color separation point.

[0013] Furthermore, the side wall of the second color separation ruler away from the plate is set as the second bonding wall, which is bonded to the side wall of the vehicle, and the lower end of the second bonding wall is set as the second color separation point.

[0014] Furthermore, the side wall of the third color-separating ruler away from the plate is set as the third bonding wall, which is bonded to the side wall of the vehicle, and the lower end of the third bonding wall is set as the third color-separating point.

[0015] Furthermore, the side wall of the third color-separating ruler away from the plate is set as the third bonding wall, which is bonded to the side wall of the vehicle, and the lower end of the third bonding wall is set as the third color-separating point.

[0016] Furthermore, the side wall of the fourth color-separating ruler away from the plate is set as the fourth bonding wall, which is bonded to the side wall of the vehicle, and the lower end of the fourth bonding wall is set as the fourth color-separating point.

[0017] Furthermore, the length of the positioning plate is greater than the length of any color separation ruler.

[0018] Furthermore, the plate sidewall is provided with multiple hand-held holes for holding the tool and fixing it to the vehicle sidewall. The width of the plate gradually decreases from the end near the positioning plate to the end away from the positioning plate, and the hand-held holes are gradually reduced in size along the direction of the gradually decreasing width of the plate. Alternatively, the width of the plate is consistent in the length direction, and the size of the hand-held holes on it is also consistent.

[0019] Furthermore, a reinforcing plate is integrally connected to the side wall of the plate, and the reinforcing plate is formed by bending the end of the plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a positioning plate, which is inserted into and attached to the lower plane of the vehicle's underframe side beam. This ensures that the first, second, third, and fourth color separation rulers on the side wall of the plate are all in contact with the vehicle's side wall. The operator fixes the fixture by holding it through the hand-held hole and marks the outline points at the first, second, third, and fourth color separation points. The fixture is moved along the length of the color strip to mark multiple outline points. The position of the color separation line is determined by pasting color separation tape that passes through the outline points at the same height, thus improving the accuracy of the color separation size setting.

Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figure 1 As shown, this utility model provides a color-separation tooling for the side wall of a rail vehicle body, including a plate 1, a positioning plate 2, multiple color-separation rulers and hand-held holes 8. The lower end of the side wall of the plate 1 is integrally connected to the positioning plate 2. The lower wall of the positioning plate 2 is flush with the lower end surface of the plate 1. The plate 1 is set on the side wall of the positioning plate 2, and multiple color-separation rulers are spaced apart along its length direction. The plate 1 is provided with multiple hand-held holes 8, which are spaced apart along the length direction of the plate 1.

[0025] Multiple color separation rulers include a first color separation ruler 3, a second color separation ruler 4, a third color separation ruler 5, and a fourth color separation ruler 6, arranged sequentially from the end closest to the positioning plate 2 to the end furthest from the positioning plate 2. The side wall of the first color separation ruler 3 furthest from the plate 1 is designated as a first bonding wall, which is bonded to the vehicle side wall. The lower end of the first bonding wall is designated as a first color separation point 31, used to mark the outline of the color strip. The side wall of the second color separation ruler 4 furthest from the plate 1 is designated as a second bonding wall, which is bonded to the vehicle side wall. The lower end of the second bonding wall is designated as a second color separation point 41, used to mark the outline of the color strip. The side wall of the third color separation ruler 5 furthest from the plate 1 is designated as a third bonding wall. The third bonding wall is attached to the side wall of the vehicle, and the lower end of the third bonding wall is set as the third color separation point 51, which is used to mark the outline point of the color strip; the side wall of the third color separation ruler 5 away from the plate 1 is set as the third bonding wall, and the third bonding wall is attached to the side wall of the vehicle, and the lower end of the third bonding wall is set as the third color separation point 51, which is used to mark the outline point of the color strip; the side wall of the fourth color separation ruler 6 away from the plate 1 is set as the fourth bonding wall, and the fourth bonding wall is attached to the side wall of the vehicle, and the lower end of the fourth bonding wall is set as the fourth color separation point 61, which is used to mark the outline point of the color strip; by marking multiple outline points in the length direction of the vehicle body, the outline line can be drawn by sticking color separation tape through the outline points at the same height, thereby determining the outline line at different heights.

[0026] The length of the positioning plate 2 is greater than the length of any color separation ruler. The positioning plate 2 extends into the lower surface of the vehicle's underframe side beam and fits against it. All the color separation rulers are set to abut against the vehicle's side wall.

[0027] The width of the plate 1 gradually decreases from the end near the positioning plate 2 to the end away from the positioning plate 2. Similarly, the multiple hand-held holes 8, also gradually decreasing in size from the end near the positioning plate 2 to the end away from the positioning plate 2, are designed to facilitate hand-holding by the operator and also to reduce overall weight. Alternatively, the width of the plate 1 can remain consistent along its length, and the size of the hand-held holes 8 on it can also remain consistent.

[0028] A reinforcing plate 7 is fixedly connected to the end of the plate 1 away from the positioning plate 2. The reinforcing plate 7 is integrally connected to the plate 1. The reinforcing plate 7 is formed by bending the end of the plate 1. The purpose is to strengthen the strength of the entire plate 1 and prevent the plate 1 from deforming.

[0029] The working principle of the color-separation fixture for the side wall of a rail vehicle provided by this utility model is as follows: The positioning plate 2 is inserted into the lower plane of the side beam of the vehicle underframe and fitted together, so that the first color separation ruler 3, the second color separation ruler 4, the third color separation ruler 5 and the fourth color separation ruler 6 set on the side wall of the plate 1 are all fitted together with the side wall of the vehicle. The operator marks the contour points at the positions of the first color separation point 31, the second color separation point 41, the third color separation point 51 and the fourth color separation point 61 by holding the hand through the hand-held hole 8. The color-separation fixture is moved along the length of the vehicle body to mark multiple contour points. Color separation tape is pasted on the contour points to form contour lines, thereby obtaining the contour lines of different color bands and improving the accuracy of color separation size setting.

[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
