Description

Technical Field

[0001] This utility model relates to the field of rail vehicle assembly technology, and in particular to rail vehicle assembly auxiliary devices. Background Technology

[0002] The opening and closing mechanism is installed at the front of the driver's cab and car body structure of rail vehicles (such as bullet trains and high-speed trains). Its main functions are to meet the aesthetic requirements and streamlined aerodynamics of the vehicle's front end, protect other components at the front of the rail vehicle, and prevent debris such as flying stones and branches from entering the rail vehicle. Typically, after the opening and closing mechanism, driver's cab, and car body structure are assembled as a whole, the gap between the opening and closing mechanism and the car body structure must be between 10mm and 2mm. Furthermore, the driver's cab and car body structure must smoothly transition to the opening and closing mechanism, with a height difference not exceeding 2mm. If the installation of the opening and closing mechanism is poor, misalignment will occur with the front of the driver's cab and car body structure, preventing a smooth transition and severely affecting the overall shape of the front of the rail vehicle.

[0003] Currently, in existing technologies, when installing the opening and closing mechanism at the front end of the driver's cab and vehicle body structure, an angle detection template and an opening and closing mechanism mounting base positioning template are first designed. Then, the angle detection template is used to measure and adjust the position of the driver's cab at multiple points. The driver's cab is then welded and fixed to the chassis of the vehicle body structure. The opening and closing mechanism mounting base positioning template is then used to measure and adjust the position of the opening and closing mechanism mounting base at multiple points. The mounting base is then welded and fixed to the front ramp of the driver's cab. The opening and closing mechanism is then connected to the mounting base. Finally, the outer contours of the driver's cab and the vehicle body structure are bonded to the outer contour of the opening and closing mechanism, ensuring that the relative positions of the opening and closing mechanism, driver's cab, and vehicle body structure meet the requirements after assembly. However, this method is inefficient, and the accuracy of positioning the relative positions of the opening and closing mechanism, driver's cab, and vehicle body structure needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for assembling rail vehicles to solve the above-mentioned problems existing in the prior art when the opening and closing mechanism is installed at the front end of the driver's cab and the car body structure.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A rail vehicle assembly auxiliary device includes a positioning frame, the positioning frame including a frame body, and a first positioning structure, a second positioning structure and a third positioning structure fixedly connected to the same side of the frame body along a first orientation;

[0007] The first positioning structure is used to position the relative position of the positioning frame and the end plate at the front end of the frame body in the length direction;

[0008] The second positioning structure is located above the first positioning structure along the second orientation. The second positioning structure is used to position the relative position of the driver's cab and the vehicle frame body. The first orientation and the second orientation are perpendicular.

[0009] The third positioning structure is used to position the mounting base of the opening and closing mechanism to fit against the front inclined plate of the driver's cab at the expected position.

[0010] As a preferred embodiment of the above-mentioned rail vehicle assembly auxiliary device, the first positioning structure includes a first reference positioning plate. The first reference positioning plate is provided with a first positioning surface, at least two insertion positioning holes and at least two first connecting holes. The first positioning surface is used to fit against the end plate along the first orientation. The insertion positioning holes are used to position the relative positions of the end plate and the positioning frame. The first connecting holes are used to detachably connect the first reference positioning plate to the end plate.

[0011] As a preferred embodiment of the above-mentioned rail vehicle assembly auxiliary device, the first positioning structure further includes a first contour positioning plate fixedly surrounding the outer periphery of the first reference positioning plate; when the front panel surrounds the side of the frame body in the width direction, the outer peripheral wall of the first contour positioning plate is coplanar with the outer side wall of the front panel.

[0012] As a preferred embodiment of the above-mentioned auxiliary device for assembling rail vehicles, the outer contour line of the first reference positioning plate is consistent with the outer contour line of the first contour positioning plate, and the distance between the outer contour line of the first reference positioning plate and the outer peripheral wall of the first contour positioning plate is equal to the thickness of the first contour positioning plate.

[0013] As a preferred embodiment of the above-mentioned rail vehicle assembly auxiliary device, the positioning frame further includes a first reinforcing rib, and the first contour positioning plate and the first reference positioning plate are fixedly connected to the frame body through the first reinforcing rib.

[0014] As a preferred embodiment of the aforementioned rail vehicle assembly auxiliary device, the second positioning structure includes:

[0015] The second reference positioning plate has a second positioning surface, which is distributed at a preset obtuse angle with the first positioning surface. The second positioning surface can fit against the front inclined plate along the first orientation.

[0016] The second contour positioning plate is fixedly disposed on the outer periphery of the second reference positioning plate; when the driver's cab is disposed on the vehicle frame body, the outer peripheral wall of the second contour positioning plate is coplanar with the outer peripheral wall of the driver's cab.

[0017] As a preferred embodiment of the above-mentioned auxiliary device for assembling rail vehicles, the outer contour line of the second reference positioning plate is consistent with the outer contour line of the second contour positioning plate, and the distance between the outer contour line of the second reference positioning plate and the outer peripheral wall of the second contour positioning plate is equal to the thickness of the second contour positioning plate.

[0018] As a preferred embodiment of the above-mentioned rail vehicle assembly auxiliary device, the third positioning structure includes a third reference positioning plate. The third reference positioning plate is provided with a third positioning surface and a positioning pin. The third positioning surface is used to fit against the mounting seat along the first orientation, and the positioning pin is used to insert and position with the mounting seat, so that when the driver's cab is set on the frame body, the mounting seat fits against the front inclined plate at the expected position.

[0019] As a preferred embodiment of the above-mentioned rail vehicle assembly auxiliary device, the frame body has a process surface formed at the bottom along the second orientation, and the process surface can abut against the top wall of the obstacle remover from top to bottom along the second orientation.

[0020] As a preferred embodiment of the aforementioned auxiliary device for assembling rail vehicles, the frame body is fixedly connected with lifting rings.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides an assembly auxiliary device for rail vehicles, used to assemble the rail vehicle frame body, driver's cab, and opening / closing mechanism into a whole. When assembling the driver's cab and opening / closing mechanism onto the frame body, the mounting seat of the opening / closing mechanism is pre-positioned on the third positioning structure. Then, the positioning frame is moved to the front end of the frame body along its length. The relative position of the end plate at the front end of the frame body along its length and the positioning frame is positioned by the first positioning structure. Since the end plate is fixedly connected to the frame body, when the relative positions of the end plate and the positioning frame are positioned, the relative positions of the frame body and the positioning frame are also positioned. Next, the driver's cab is moved above the frame body and supported on it. The relative position of the driver's cab and the frame body is positioned by the second positioning structure. When the relative positions of the driver's cab and the frame body are positioned, the third positioning structure simultaneously positions the mounting seat on the third positioning structure. The driver's cab is aligned with the front ramp plate at the intended location. The driver's cab is then initially welded and fixed to the frame body, and the mounting base is initially welded and fixed to the front ramp plate. The rail vehicle assembly auxiliary device is then detached from the end plate and mounting base, and moved away from the frame body and driver's cab. The portion of the driver's cab obscured by the rail vehicle assembly auxiliary device is welded and fixed to the frame body, and the portion of the mounting base obscured by the rail vehicle assembly auxiliary device is welded and fixed to the front ramp plate, thus completing the assembly of the driver's cab, mounting base, and frame body. After the driver's cab, mounting base, and frame body are painted as a whole, the opening and closing mechanism is fixedly connected to the mounting base, completing the assembly of the opening and closing mechanism. Because the relative positions of the driver's cab, mounting base, and frame body are accurately positioned, the positioning of the opening and closing mechanism is also accurate. Therefore, compared to existing technologies, this method effectively improves the accuracy and efficiency of positioning the relative positions of the frame body, driver's cab, and opening and closing mechanism, thereby effectively improving the efficiency and quality of assembling the frame body, driver's cab, and opening and closing mechanism into a whole.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] like Figure 1-7 As shown, this utility model provides a rail vehicle assembly auxiliary device, which includes a positioning frame 1. The positioning frame 1 includes a frame body 11 and a first positioning structure 12, a second positioning structure 13, and a third positioning structure fixedly connected to the frame body 11 on the same side along a first orientation. This rail vehicle assembly auxiliary device is used to assemble the rail vehicle frame body 100, driver's cab, and opening / closing mechanism 200 into a whole. By using this rail vehicle assembly auxiliary device to assemble the rail vehicle frame body 100, driver's cab, and opening / closing mechanism 200 into a whole, the accuracy and efficiency of positioning the relative positions of the frame body 100, driver's cab, and opening / closing mechanism 200 can be effectively improved, thereby effectively improving the efficiency and quality of assembling the frame body 100, driver's cab, and opening / closing mechanism 200 into a whole. The specific structures of the frame body 100, driver's cab, and opening / closing mechanism 200 are all prior art, and therefore will not be described in detail here.

[0044] like Figure 1-7As shown, the first positioning structure 12 is used to position the relative position of the end plate 110 at the front end of the frame body 100 along its length and the positioning frame 1; the second positioning structure 13 is located above the first positioning structure 12 along a second orientation, and is used to position the relative position of the driver's cab and the frame body 100, with the first and second orientations being perpendicular; the third positioning structure is used to position the mounting base 210 of the opening and closing mechanism 200 to fit against the front ramp 300 of the driver's cab at the expected position. Specifically, the included angle between the end plate 110 and the front ramp 300 is equal to a preset obtuse angle.

[0045] When assembling the driver's cab and the opening / closing mechanism 200 onto the frame body 100, the mounting base 210 of the opening / closing mechanism 200 is pre-positioned on the third positioning structure; or, after the relative positions of the frame body 100 and the positioning frame 1 are positioned, the mounting base 210 of the opening / closing mechanism 200 is positioned on the third positioning structure.

[0046] Taking the assembly of the driver's cab and the opening / closing mechanism 200 onto the frame body 100 as an example, the mounting base 210 of the opening / closing mechanism 200 is pre-positioned on the third positioning structure. The positioning frame 1 is moved to the front end of the frame body 100, and the relative position of the end plate 110 at the front end of the frame body 100 along its length and the positioning frame 1 is positioned by the first positioning structure 12. Since the end plate 110 is fixedly connected to the frame body 100, when the relative position of the end plate 110 and the positioning frame 1 is positioned, the relative position of the frame body 100 and the positioning frame 1 is also positioned. The driver's cab is then moved above the frame body 100 and supported on it. The relative position of the driver's cab and the frame body 100 is positioned by the second positioning structure 13. When the relative position of the driver's cab and the frame body 100 is positioned, the third positioning structure simultaneously causes the mounting base 210 to fit against the front ramp 300 of the driver's cab at the expected position. The driver's cab is then initially... The mounting base 210 is initially welded and fixed to the front inclined plate 300, and then the rail vehicle assembly auxiliary device is removed from the end plate 110 and the mounting base 210, and moved away from the rail vehicle assembly auxiliary device from the rail vehicle body 100 and the driver's cab. Then, the part of the driver's cab that is covered by the rail vehicle assembly auxiliary device is welded and fixed to the rail vehicle body 100, and the part of the mounting base 210 that is covered by the rail vehicle assembly auxiliary device is welded and fixed to the front inclined plate 300 to complete the assembly of the driver's cab, the mounting base 210 and the rail vehicle body 100. After the overall assembly of the driver's cab, the mounting base 210 and the rail vehicle body 100 is painted, the opening and closing mechanism 200 is fixedly connected to the mounting base 210 to complete the assembly of the opening and closing mechanism 200. Because the relative positions of the driver's cab, mounting base 210, and frame body 100 are accurately positioned, the opening and closing mechanism 200 is also accurately positioned. Therefore, compared with the prior art, the accuracy and efficiency of positioning the relative positions of the frame body 100, driver's cab, and opening and closing mechanism 200 can be effectively improved, thereby effectively improving the efficiency and quality of assembling the frame body 100, driver's cab, and opening and closing mechanism 200 into a whole.

[0047] Among them, such as Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the first positioning structure 12 includes a first reference positioning plate 121. The first reference positioning plate 121 is provided with a first positioning surface 12111, at least two insertion positioning holes 12112 and at least two first connecting holes 12113. The first positioning surface 12111 is used to fit against the end plate 110 along a first orientation. The insertion positioning holes 12112 are used to position the relative positions of the end plate 110 and the positioning frame 1. The first connecting holes 12113 are used to detachably connect the first reference positioning plate 121 to the end plate 110. Specifically, when assembling the driver's cab and opening / closing mechanism 200 onto the frame body 100, the positioning frame 1 is moved to the front end of the frame body 100 along its length, so that at least two insertion positioning holes 12112 are inserted and positioned one-to-one with each pin on the end plate 110. Then, the position of the positioning frame 1 is finely adjusted so that the first positioning surface 12111 is in contact with the end plate 110 along the first orientation, and at least two first connecting holes 12113 are connected one-to-one with each through hole on the end plate 110. Then, the end plate 110 and the frame body 100 are detachably connected through the first connecting holes 12113 to fix the relative position of the frame body 100 and the positioning frame 1. Specifically, a first bolt passes through the first connecting hole 12113 and the corresponding through hole on the end plate 110 and is threadedly connected to a first nut to achieve a detachable connection between the end plate 110 and the frame body 100 through the first connecting hole 12113. The pins on the end plate 110 are pins that the end plate 110 itself has.

[0048] Preferably, such as Figure 5 and Figure 6 As shown, the first connecting hole 12113 is an elongated hole. This facilitates adjustment so that at least two of the first connecting holes 12113 correspond one-to-one with the through holes on the end plate 110, and also facilitates the detachable connection of the first reference positioning plate 121 and the end plate 110 using the first bolt and the first nut. As an alternative, the shape and size of the first connecting hole 12113 are the same as those of the through holes on the end plate 110.

[0049] Optionally, such as Figure 5 and Figure 6As shown, the first reference positioning plate 121 includes at least two independent first sub-positioning plates 1211. A first positioning surface 12111 is formed on the at least two first sub-positioning plates 1211. This facilitates the processing of the second reference positioning plate 131. In this embodiment, the exemplary configuration of the first reference positioning plate 121 includes three independent first sub-positioning plates 1211. Two of the first sub-positioning plates 1211 are symmetrically distributed along a third orientation on both sides of another first sub-positioning plate 1211. Each first sub-positioning plate 1211 is provided with a first connecting hole 12113, and the two symmetrically distributed first sub-positioning plates 12111 are each provided with an insertion positioning hole 12112. Specifically, the location and number of the first connecting holes 12113 are determined according to the location and number of through holes on the end plate 110, and are consistent with the location and number of through holes on the end plate 110. The position and number of the insertion positioning holes 12112 are determined according to the position and number of the pins on the end plate 110, and are consistent with the position and number of the pins on the end plate 110.

[0050] In this embodiment, as Figure 5 and Figure 6 As shown, preferably, the end face of each first sub-positioning plate 1211 near the end plate 110 forms a first positioning surface 12111.

[0051] As an alternative, the first reference positioning plate 121 can also be set as a single piece, that is, the first reference positioning plate 121 can be integrally formed or formed by splicing and fixing multiple first sub-positioning plates 1211. Among them, the splicing and fixing methods are welding, threaded connection, etc.

[0052] It is understood that after the positioning frame 1 is fixed to the frame body 100, the positioning frame 1 is located at the front end of the frame body 100 in the length direction. The first orientation is parallel to the length direction of the frame body 100. The second orientation is parallel to the height direction of the frame body 100. The third orientation is parallel to the width direction of the frame body 100. Specifically, Figure 7 The direction ab in the diagram is the first orientation; Figure 5 and Figure 7 The cd direction in the diagram is the second orientation; Figure 5 and Figure 7 The ef direction in the equation is the third orientation.

[0053] Among them, such as Figure 1-7As shown, the first positioning structure 12 also includes a first contour positioning plate 122 fixedly surrounding the first reference positioning plate 121; when the front panel 400 surrounds the side of the frame body 100 in the width direction, the outer peripheral wall of the first contour positioning plate 122 is coplanar with the outer side wall of the front panel 400. Specifically, after the mounting base 210 is welded and fixed to the front inclined plate 300, and before the rail vehicle assembly auxiliary device is removed from the end plate 110 and the mounting base 210, the front panel 400 is surrounded on the side of the frame body 100 in the width direction, and the shape and setting position of the front panel 400 are adjusted until the outer peripheral wall of the first contour positioning plate 122 is coplanar with the outer side wall of the front panel 400, thereby enabling convenient, quick and accurate positioning of the relative position of the front panel 400 and the frame body 100. Specifically, the front panel 400 abuts against and is fixed to the end plate 110 along the length direction of the frame body 100.

[0054] Specifically, such as Figure 3 and Figure 4 As shown, there are two front bulkheads 400. When the two front bulkheads 400 are arranged on both sides of the frame body 100 in the width direction, the outer side walls of the two front bulkheads 400 are coplanar with the outer peripheral wall of the first contour positioning plate 122.

[0055] Preferably, such as Figure 4-6 As shown, the outer contour line of the first reference positioning plate 121 has the same shape as the outer contour line of the first contour positioning plate 122, and the distance between the outer contour line of the first reference positioning plate 121 and the outer peripheral wall of the first contour positioning plate 122 is equal to the thickness of the first contour positioning plate 122. That is, in this embodiment, the outer contour line formed by the three first sub-positioning plates 1211 has the same shape as the outer contour line of the first contour positioning plate 122, and the distance between the outer contour line formed by the three first sub-positioning plates 1211 and the outer contour line of the first contour positioning plate 122 is equal to the thickness of the first contour positioning plate 122. This configuration allows for a relatively intuitive determination of the relative positions of the positioning frame 1 and the end plate 110 using the outer contour of the first reference positioning plate 121, thereby improving the accuracy and efficiency of the relative positions of the positioning frame body 100 and the positioning frame 1. Secondly, when manufacturing the rail vehicle assembly auxiliary device, the shape of the first contour positioning plate 122 can be directly adjusted using the outer contour of the first reference positioning plate 121, enabling the first contour positioning plate 122 to be accurately and efficiently bent into the desired shape. It also facilitates the positioning of the first contour positioning plate 122 fixed on the frame body 11, thereby effectively reducing the processing difficulty and scrap rate of the rail vehicle assembly auxiliary device and improving its processing efficiency and quality.

[0056] Preferably, such as Figure 4 and Figure 7As shown, the positioning frame 1 also includes a first reinforcing rib 15, and the first contour positioning plate 122 and the first reference positioning plate 121 are fixedly connected to the frame body 11 through the first reinforcing rib 15. This achieves the fixed connection of the first contour positioning plate 122 and the first reference positioning plate 121 to the frame body 11, and effectively improves the reliability of the first contour positioning plate 122 and the first reference positioning plate 121, reducing the risk of deformation of the first contour positioning plate 122 and the first reference positioning plate 121. Specifically, the fixed connection method is welding, threaded connection, etc.

[0057] More preferably, such as Figure 4 and Figure 7 As shown, there are multiple first reinforcing ribs 15, which are spaced apart along the arc extension direction of the first contour positioning plate 122. This can further improve the reliability of the first contour positioning plate 122 and the first reference positioning plate 121, and further reduce the risk of deformation of the first contour positioning plate 122 and the first reference positioning plate 121.

[0058] Among them, such as Figure 1-7 As shown, the second positioning structure 13 includes a second reference positioning plate 131 and a second contour positioning plate 132. The second reference positioning plate 131 is provided with a second positioning surface 13111. The second positioning surface 13111 and the first positioning surface 12111 are distributed at a preset obtuse angle. The second positioning surface 13111 can fit against the front inclined plate 300 along the first orientation. The second contour positioning plate 132 is fixedly disposed on the outer periphery of the second reference positioning plate 131. When the driver's cab is disposed on the frame body 100, the outer peripheral wall of the second contour positioning plate 132 is coplanar with the outer peripheral wall of the driver's cab.

[0059] Specifically, after the positioning frame 1 is fixed to the vehicle frame body 100, the driver's cab is moved above the vehicle frame body 100 and supported on it. The second positioning surface 13111 is adjusted to fit against the front ramp 300 of the driver's cab along the first orientation. Then, the position of the driver's cab is finely adjusted so that the outer peripheral wall of the second contour positioning plate 132 is coplanar with the outer peripheral wall of the driver's cab. At this time, the relative position of the driver's cab and the vehicle frame body 100 is positioned. When the second positioning surface 13111 fits against the front ramp 300 of the driver's cab along the first orientation, and the outer peripheral wall of the second contour positioning plate 132 is coplanar with the outer peripheral wall of the driver's cab, the third positioning structure simultaneously makes the mounting seat 210 fit against the front ramp 300 of the driver's cab at the expected position. Then, the driver's cab is welded and fixed to the vehicle frame body 100, and the mounting seat 210 is welded and fixed to the front ramp 300 to initially fix the relative position of the driver's cab and the vehicle frame body 100, and initially fix the relative position of the driver's cab and the mounting seat 210.

[0060] Preferably, such as Figure 5As shown, the second reference positioning plate 131 is provided with at least two second connecting holes 13112. The second connecting holes are used to detachably connect the second reference positioning plate 131 to the front inclined plate 300. With this configuration, once the driver's cab is positioned, its position can be fixed, facilitating the initial welding and fixing of the driver's cab and the frame body 100, and facilitating the welding and fixing of the front inclined plate 300 and the mounting base 210. This avoids displacement of the driver's cab under external force during the welding and fixing process, thereby further improving the efficiency and quality of assembling the frame body 100, driver's cab, and opening and closing mechanism 200 into a whole.

[0061] More preferably, such as Figure 5 As shown, the second connecting hole 13112 is an elongated hole. This facilitates the connection of at least two second connecting holes 13112 with each of the through holes on the front inclined plate 300, and also facilitates the detachable connection of the second reference positioning plate 131 and the front inclined plate 300 using the second bolt and the second nut. As an alternative, the first connecting hole 12113 has the same shape and size as the through hole on the front inclined plate 300.

[0062] Optionally, such as Figure 5 and Figure 6 As shown, the second reference positioning plate 131 includes at least two independent second sub-positioning plates 1311. A second positioning surface 13111 is formed on the at least two second sub-positioning plates 1311. This facilitates the processing of the second reference positioning plate 131. In this embodiment, the exemplary configuration of the second reference positioning plate 131 includes three independent second sub-positioning plates 1311. Two of the second sub-positioning plates 1311 are symmetrically distributed along a third orientation on both sides of another second sub-positioning plate 1311. Each second sub-positioning plate 1311 is provided with a second connecting hole 13112. Specifically, the location and number of the second connecting holes 13112 are determined based on the location and number of through holes on the front inclined plate 300, and are consistent with the location and number of through holes on the front inclined plate 300.

[0063] In this embodiment, as Figure 5 and Figure 6 As shown, preferably, the end face of each second sub-positioning plate 1311 near the front inclined plate 300 forms a second positioning surface 13111.

[0064] As an alternative, the second reference positioning plate 131 can also be set as a single piece, that is, the second reference positioning plate 131 can be integrally formed or formed by splicing and fixing multiple second sub-positioning plates 1311. Among them, the splicing and fixing methods are welding, threaded connection, etc.

[0065] Preferably, such as Figure 5 and Figure 6As shown, the outer contour line of the second reference positioning plate 131 has the same shape as the outer contour line of the second contour positioning plate 132, and the distance between the outer contour lines of the second reference positioning plate 131 and the second contour positioning plate 132 is equal to the thickness of the second contour positioning plate 132. That is, in this embodiment, the outer contour line formed by the three second sub-positioning plates 1311 has the same shape as the outer contour line of the second contour positioning plate 132, and the distance between the outer contour line formed by the three second sub-positioning plates 1311 and the outer contour line of the second contour positioning plate 132 is equal to the thickness of the second contour positioning plate 132. This configuration allows for a relatively intuitive determination of the relative position of the positioning frame 1 and the driver's cab using the outer contour of the second reference positioning plate 131, thereby improving the accuracy and efficiency of positioning the relative position of the driver's cab and the positioning frame 1. Secondly, when manufacturing the rail vehicle assembly auxiliary device, the shape of the second contour positioning plate 132 can be directly adjusted using the outer contour of the second reference positioning plate 131, enabling the second contour positioning plate 132 to be accurately and efficiently bent into the desired shape. It also facilitates positioning the second contour positioning plate 132 and fixing it to the frame body 11, thereby further reducing the processing difficulty and scrap rate of the rail vehicle assembly auxiliary device and further improving its processing efficiency and quality.

[0066] Preferably, in this embodiment, such as Figure 4-7 As shown, the two free ends of the first profile plate are fixedly connected to the two free ends of the second profile plate in a one-to-one correspondence, forming an annular profile plate. When the driver's cab is installed on the frame body 100, the outer peripheral wall of the driver's cab and the outer peripheral walls of the two front bulkheads 400 form an integral outer wall, and the outer peripheral wall of the annular profile plate and the integral outer wall are coplanar. This can further improve the accuracy and efficiency of positioning the relative position of the driver's cab and the positioning frame 1, and can further improve the processing efficiency and quality of the rail vehicle assembly auxiliary device.

[0067] Preferably, such as Figure 4 and Figure 7 As shown, the positioning frame 1 also includes a second reinforcing rib 16, and the second contour positioning plate 132 and the second reference positioning plate 131 are fixedly connected to the frame body 11 through the second reinforcing rib 16. This achieves the fixed connection of the second contour positioning plate 132 and the second reference positioning plate 131 to the frame body 11, and effectively improves the reliability of the second contour positioning plate 132 and the second reference positioning plate 131, reducing the risk of deformation of the second contour positioning plate 132 and the second reference positioning plate 131. Specifically, the fixed connection method is welding, threaded connection, etc.

[0068] More preferably, such as Figure 4 and Figure 7As shown, there are multiple second reinforcing ribs 16, which are spaced apart along the arc extension direction of the second contour positioning plate 132. This can further improve the reliability of the second contour positioning plate 132 and the second reference positioning plate 131, and further reduce the risk of deformation of the second contour positioning plate 132 and the second reference positioning plate 131.

[0069] Among them, such as Figure 2 , Figure 5 and Figure 6 As shown, the third positioning structure includes a third reference positioning plate 14. The third reference positioning plate 14 is provided with a third positioning surface 141 and a positioning pin 142. The third positioning surface 141 is used to fit against the mounting seat 210 along the first orientation, and the positioning pin 142 is used to insert and position with the mounting seat 210 so that when the driver's cab is set on the frame body 100, the mounting seat 210 fits against the front inclined plate 300 at the expected position.

[0070] Specifically, when assembling the driver's cab and opening / closing mechanism 200 onto the frame body 100, the mounting base 210 is pre-inserted into the positioning pin 142 and the mounting base 210 is aligned with the third positioning surface 141 along the first orientation to define the mounting position of the mounting base 210 on the positioning frame 1. Alternatively, after the relative positions of the frame body 100 and the positioning frame 1 are determined, the mounting base 210 is inserted into the positioning pin 142 and aligned with the third positioning surface 141 along the first orientation to define the mounting position of the mounting base 210 on the positioning frame 1. Thus, when the relative positions of the driver's cab and the frame body 100 are determined, the mounting base 210 is aligned with the front ramp 300 at the expected position. The positioning pin 142 is inserted into the existing holes on the mounting base 210, facilitating the installation and removal of the mounting base 210 without requiring additional adjustments to its structure.

[0071] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, there are seven mounting bases 210, so there are seven third reference positioning plates 14. The seven mounting bases 210 and the seven third reference positioning plates 14 are set in a one-to-one correspondence.

[0072] Optionally, such as Figure 2 and Figure 6As shown, a process surface 111 is formed on the bottom of the frame body 11 along the second orientation. The process surface 111 can abut against the top wall of the obstacle remover 500 from top to bottom along the second orientation. When the rail vehicle assembly auxiliary device is moved to the front end of the frame body 100 in the length direction, the process surface 111 can roughly define the setting position of the positioning frame 1 along the second orientation, and the cooperation between the process surface 111 and the top wall of the obstacle remover 500 can support the rail vehicle assembly auxiliary device to avoid mutual interference, and facilitate the adjustment of the relative position of the rail vehicle assembly auxiliary device and the frame body 100. Specifically, when the relative position of the positioning frame 1 and the frame body 100 is positioned, the process surface 111 is located on the top wall of the obstacle remover 500 along the second orientation.

[0073] Among them, such as Figure 7 As shown, the frame body 11 is fixedly connected with lifting rings 112. In this embodiment, two lifting rings 112 are provided for example. The rail vehicle assembly auxiliary device is moved to the front end of the frame body 100 in the length direction by hoisting, and then positioned with the end plate 110 by the first positioning surface 12111, the insertion positioning hole 12112, and the end plate 110. Then, the first reference positioning plate 121 and the end plate 110 are fixed by the first connecting hole 12113 to achieve the purpose of fixing the relative position of the frame 1 and the frame body 100.

[0074] In this embodiment, as Figure 4-7 As shown, the frame body 11 is formed by welding together multiple square tubes. In other embodiments, the frame body 11 may also be formed by welding together multiple round tubes, etc.

[0075] Specifically, the rail vehicle assembly auxiliary device of this embodiment assembles the frame body 100, driver's cab, mounting base 210, and opening / closing mechanism 200 into a whole, which can save at least 1.5 hours compared with the prior art. Specifically, assembling the driver's cab to the frame body 100 can save at least 1 hour; assembling the opening / closing mechanism 200 can save at least 0.5 hours.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
