Description

Technical Field

[0001] This invention relates to the field of rail vehicle manufacturing, and in particular to a method for controlling the installation of interior components in the passenger compartment of a rail vehicle. Background Technology

[0002] The interior decoration of rail vehicle passenger compartments mainly includes components such as passenger compartment end walls, driver's cab partition walls, vertical covers, side wall panels, side roof panels, air supply grilles, and central roof panels. The installation sequence is generally passenger compartment end walls, driver's cab partition walls, vertical covers, side wall panels, central roof panels, side roof panels, and air supply grilles. The traditional process is to install the passenger compartment end walls and driver's cab partition walls first. After the end walls are installed, the distance from the door center to the end wall is measured. The end walls are bolted to the floor, connected to the top of the car body at the top, and connected to the side walls of the car body at the sides. Before installation, the width of the car body door is measured to find the door centerline. The positioning dimension is the distance from the door centerline to the bottom of the end wall. This results in the end walls being inconsistent with the center of the car door after installation, with some tilting inward or outward. At the same time, the vertical cover panels are installed using the car door centerline as the reference for positioning. Due to the deflection of the car body, the center distance of each door is inconsistent with the theoretical center distance after welding. Therefore, if the interior vertical cover panels are installed using the door centerline as the reference, the spacing of the vertical cover panels will inevitably change with the center distance of the car doors after installation. Summary of the Invention

[0003] The purpose of this invention is to provide a method for controlling the installation of interior panels in a rail vehicle passenger compartment, in order to solve the problems existing in the prior art. This method ensures that the end walls are aligned vertically with the center of the car door after installation, guarantees a flat surface for the end wall cabinets, and adjusts the installation reference of the vertical cover panels according to the actual size data of the car, accurately calculates the size of each vertical cover panel, and ensures that the gaps between the vertical cover panels are uniform and the overall appearance is aesthetically pleasing after installation.

Adjust the position of the upper cabinet so that the bottom edge of the upper cabinet is flush with the top edge of the left cabinet and the top edge of the right cabinet at the docking position. Control the positional deviation of the upper cabinet to meet the requirements. Then connect the upper cabinet and the left and right cabinets together with fasteners to form the end wall of the carriage.

[0025] S206. Based on the design baseline obtained in S205, divide the left side of the design baseline into n regions. The design length of each region is c1, c2, ..., cn, respectively. The average installation deviation of each region to the left of the actual baseline is w1, where w1 = (b1w - B1) / n.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The purpose of this invention is to provide a method for controlling the installation of interior panels in a rail vehicle passenger compartment, in order to solve the problems existing in the prior art. This method ensures that the end walls are aligned vertically with the center of the car door after installation, guarantees a flat surface for the end wall cabinets, and adjusts the installation reference of the vertical cover panels according to the actual size data of the car, accurately calculates the size of each vertical cover panel, and ensures that the gaps between the vertical cover panels are uniform and the overall appearance is aesthetically pleasing after installation.

[0048] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] This invention provides a method for controlling the installation of interior components in the passenger compartment of a rail vehicle, including an end-wall installation control method, the steps of which are as follows:

[0050] S101, such as Figure 1 As shown, measure and confirm the vertical symmetrical center line of the end door of the carriage, and confirm the intersection of the vertical symmetrical center line and the upper edge of the door frame.

[0051] S102. Check the completion status of the pre-processing at the end of the car body. The pre-processing includes opening mounting holes at the end of the car body and installing wiring.

[0052] S103, such as Figure 1As shown, the upper cabinet is connected to the top of the vehicle body. The upper cabinet is close to the inner wall of the end of the vehicle body and the inner wall of the top. In this step, the upper cabinet is temporarily connected to the top of the vehicle body.

[0053] S104. Place the left cabinet below the upper cabinet and on the left side of the carriage, with the left cabinet close to the inner wall at the end and the inner wall on the side of the carriage.

[0054] S105, such as Figure 1 As shown, the horizontal distance between the end face of the left cabinet closest to the adjacent door frame and the center of the upper edge of the door frame is a1, and the horizontal distance between the end face of the left cabinet closest to the adjacent door frame and the center of the lower edge of the door frame is a2. Confirm whether the difference between a1 and a2 meets the requirements. If it does not meet the requirements, adjust the position of the left cabinet until the difference between a1 and a2 meets the requirements. In a preferred embodiment, the difference between a1 and a2 is not greater than 2mm. When the difference between a1 and a2 is greater than 2mm, adjust the tilt of the left cabinet until the deviation between a1 and a2 is not greater than 2mm. The tilt of the left cabinet can be achieved by adding shims to the bottom of the left cabinet.

[0055] S106. Fix the left cabinet to the carriage floor. Specifically, drill and tap holes at the connection between the left cabinet and the carriage floor, then install fasteners to fix the left cabinet to the carriage floor. After fixing, retest to confirm whether the difference between a1 and a2 meets the requirements. If it does not meet the requirements, remove the fasteners and adjust according to S105.

[0056] S107. Place the right cabinet below the upper cabinet and on the right side of the carriage, with the right cabinet close to the inner wall of the end and the inner wall of the side of the carriage.

[0057] S108. The horizontal distance between the end face of the right cabinet on the side closest to the adjacent door frame and the center of the upper edge of the door frame is a1', and the horizontal distance between the end face of the right cabinet on the side closest to the adjacent door frame and the center of the lower edge of the door frame is a2'. Confirm whether the difference between a1' and a2' meets the requirements. If it does not meet the requirements, adjust the position of the right cabinet until the difference between a1' and a2' meets the requirements. In a preferred embodiment, the difference between a1' and a2' is not greater than 2mm. When the deviation between a1' and a2' is greater than 2mm, adjust the cabinet tilt of the right cabinet until the difference between a1' and a2' is not greater than 2mm. The tilt of the right cabinet can be achieved by adding shims to the bottom of the right cabinet.

[0058] S109. Fix the right-side cabinet to the carriage floor. Specifically, drill and tap holes at the connection between the right-side cabinet and the carriage floor, then install fasteners to fix the right-side cabinet to the carriage floor. After fixing, re-measure to confirm whether the difference between a1' and a2' meets the requirements. If it does not meet the requirements, remove the fasteners and adjust according to S108.

[0059] S110, such as Figure 2 As shown, the vertical flatness of the left cabinet is measured using the fourth measuring line as a reference, and the vertical flatness of the right cabinet is measured using the fifth measuring line as a reference. This confirms whether the vertical flatness of the left and right cabinets meets the requirements. Both the fourth and fifth measuring lines are perpendicular to the carriage floor and are measured using a vertical level. In a preferred embodiment, the vertical flatness of both the left and right cabinets is no greater than 2mm.

[0060] S111, such as Figure 2 As shown, the second and third measuring lines are measured to obtain the horizontal flatness of the left and right cabinets, and to confirm whether the horizontal flatness of the left and right cabinets meets the requirements. The second measuring line is located at the lower edge of the upper cabinet and is parallel to the floor of the carriage. The third measuring line is the line connecting the bent parts of the carriage side wall and is parallel to the floor of the carriage. In a preferred embodiment, the horizontal flatness of both the left and right cabinets is no greater than 2mm.

[0061] S112. Adjust the position of the upper cabinet so that the bottom edge of the upper cabinet is flush with the top edges of the left and right cabinets at the joint. Control the positional deviation of the upper cabinet to meet the requirements. The positional deviation is obtained by measuring the first measuring line, which is located on the surface of the upper cabinet and parallel to the carriage floor. Then, connect the upper cabinet to the left and right cabinets together with fasteners. Figure 3 As shown, the end wall forming the carriage, in a preferred embodiment, has a positional deviation of the upper cabinet of no more than 1 mm.

[0062] S113. Measure the vertical flatness of the upper cabinet relative to the left and right cabinets to confirm whether the flatness meets the requirements. In a preferred embodiment, the vertical flatness of the upper cabinet relative to the left and right cabinets is not greater than 2mm. When the vertical flatness of the upper cabinet relative to the left and right cabinets is greater than 2mm, adjust the front and rear positions of the upper cabinet and the vehicle body until the vertical flatness of the upper cabinet relative to the left and right cabinets is not greater than 2mm.

[0063] The present invention also includes a method for controlling the installation of the cover plate, the steps of which are as follows:

[0064] S201. Confirm the position of the design baseline of the carriage according to the drawings. The vertical distance between the design baseline and the left end wall in the horizontal direction on the drawings is B1. The vertical distance between the design baseline and the right end wall in the horizontal direction is B2.

[0065] S202. Measure the vertical distance between the design baseline and the actual horizontal direction of the two end walls. The vertical distance between the design baseline and the left end wall is b1, and the vertical distance between the design baseline and the right end wall is b2.

[0066] S203. Calculate the average difference between the design length and the actual length of the area on both sides of the design baseline. , ={(b1+b2)-(B1+B2)} / 2.

[0067] S204. Calculate the measurement center dimension b1w on the left side of the design baseline and the measurement center dimension b2w on the right side of the design baseline, respectively. b1w = B1 + b2w = B2 + .

[0068] S205. Calculate the offset Δ of the design baseline and adjust the position of the design baseline. Δ = b1w - b1. When Δ > 0, adjust the length of |Δ| to the right of the design baseline. When Δ < 0, adjust the length of |Δ| to the left of the design baseline. When Δ = 0, do not adjust the position of the design baseline.

[0069] S206. Based on the design baseline obtained in S205, divide the left side of the design baseline into n regions. The design length of each region is c1, c2, ..., cn. The average installation deviation of each region on the left side of the actual baseline is w1, w1=(b1w-B1) / n. The actual length of each region on the left side of the actual symmetry center line is (c1+w1), (c2+w1), ..., (cn+w1). When w1 is less than 0, the actual length of each region on the left side of the actual baseline is shorter than the design length. When w1 is greater than 0, the actual length of each region on the left side of the actual baseline is longer than the design length.

[0070] Divide the right side of the design baseline into m regions, with the design lengths of each region being d1, d2, ..., dm. The average installation deviation of each region on the right side of the actual baseline is w2, where w2 = (b2w - B2) / m. The actual lengths of each region on the right side of the actual symmetrical center line are (d1 + w2), (d2 + w2), ..., (dm + w2). When w2 is less than 0, the actual length of each region on the right side of the actual baseline is shorter than the design length; when w2 is greater than 0, the actual length of each region on the right side of the actual baseline is longer than the design length.

[0071] S207. Starting from the actual baseline and based on the calculation results in S206, lay vertical cover plates that meet the size requirements along the inner wall of the carriage towards both ends of the carriage.

[0072] like Figure 4-6 As shown, assuming B1 and B2 are both 8350mm, b1 is 8352mm, and b2 is 8356mm, then ={(8356+8352)-(8350+8350)} / 2=8 / 2=4mm, b1w=8350+4=8354mm, b2w=8350+4=8354mm, then calculate Δ=b1w-b1=8354-8352=2mm. Therefore, the position of the design baseline needs to be adjusted 2mm to the right. The actual position of the baseline is marked on the carriage according to the calculated position, and the offset between the actual and calculated positions is remeasured and confirmed to meet the requirements. In a preferred embodiment, the offset between the actual and calculated positions of the baseline is no greater than 1mm. Figure 5 and 6 As shown, n takes a value of 5 and m takes a value of 5. The average installation deviation w1 in each area to the left of the actual baseline is (8354-8350) / 5 = 0.8mm, and the average installation deviation w2 in each area to the right of the actual baseline is (8354-8356) / 5 = -0.4mm. That is, the actual length of each area to the left of the actual baseline is 0.8mm longer than the design length, and the actual length of each area to the right of the actual baseline is 0.4mm shorter than the design length.

[0073] Assuming B1 is 8350mm, B2 is 8340mm, b1 is 8352mm, and b2 is 8344mm, then =3mm, b1w=8353mm, b2w=8343mm, and then calculate Δ=1mm. Therefore, the position of the design baseline needs to be adjusted to the right by 1mm. Mark the actual position of the actual baseline on the carriage according to the calculated position of the actual baseline, and remeasure and confirm whether the offset between the actual position and the calculated position of the actual baseline meets the requirements. n is 5 and m is 5. The average installation deviation w1=0.2mm in each area to the left of the actual baseline and the average installation deviation w2=-0.2mm in each area to the right of the actual baseline. That is, the actual length of each area to the left of the actual baseline is 0.2mm longer than the design length, and the actual length of each area to the right of the actual baseline is 0.2mm shorter than the design length.

[0074] Assuming B1 is 8350mm, B2 is 8340mm, b1 is 8344mm, and b2 is 8338mm, then =-4mm, b1w=8346mm, b2w=8336mm, and then calculate Δ=2mm. Therefore, the position of the design baseline needs to be adjusted to the right by 2mm. Mark the actual position of the actual baseline on the carriage according to the calculated position of the actual baseline, and remeasure and confirm whether the offset between the actual position and the calculated position of the actual baseline meets the requirements. n is 5 and m is 5. The average installation deviation w1 in each area to the left of the actual baseline is -0.8mm, and the average installation deviation w2 in each area to the right of the actual baseline is -0.8mm. That is, the actual length of each area to the left of the actual baseline is 0.8mm shorter than the design length, and the actual length of each area to the right of the actual baseline is 0.8mm shorter than the design length.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
