Description

Technical Field

[0001] The invention belongs to the field of welding assembly auxiliary devices for rail vehicle bogie guide wheel assemblies, and in particular relates to an assembly tool for rail passenger vehicle bogie guide wheel assemblies. Background Art

[0002] like Figures 1 to 7 As shown, the bogie guide wheel assembly of a rail vehicle is also called a bogie guide wheel mechanism. It is an integral structural member formed by assembling and welding an obtuse-angled outer plate 1, two rib plates 3, a right-angled inner plate 2, and two guide wheel connecting blocks 4. The outer plate 1 has a thickness of k1, and the inclined plate 1-1 and the forked horizontal cover plate 1-2 thereon form an obtuse angle of 110° with each other, and the two are connected by an arc plate 1-3. The vertical height from the edge of the inclined plate 1-1 to the end face of the forked horizontal cover plate 1-2 is H1, and the vertical height of the vertical plate 2-2 on the inner plate 2 is H2. The guide wheel connecting block 4 is a rectangular block with a vertical thickness of H3 and a horizontal length that is the same as the horizontal length of the forked horizontal cover plate 1-2. The inner plate 2 has a thickness of k2, and the horizontal plate 2-1 and the forked horizontal cover plate 1-2 thereon are both rectangular. The two are arranged in parallel, and the three sides of the two rectangles overlap in the vertical projection direction. The rib plate 3 is approximately a right-angled trapezoid, with a circular chamfer 3-1-4 corresponding to the circular arc plate 1-3 at the obtuse angle between its upper trapezoidal base 3-1-5 and the hypotenuse 3-1-3. The right-angled 3-1-2 sides of the rib plate 3 are welded to the outer wall of the vertical plate 2-2 and the end face of the guide wheel connecting block 4, respectively. The trapezoidal upper base 3-1-5 of the rib plate 3 is welded to the inner end face of the forked horizontal cover plate 1-2. The circular chamfer 3-1-4 of the rib plate 3 is welded to the circular arc plate 1-3, and the trapezoidal hypotenuse 3-1-3 of the rib plate 3 is welded to the inner end face of the inclined plate 1-1. The lower edges of the inclined plate 1-1 and the vertical plate 2-2 are coplanar with the outer wall of the trapezoidal lower base 3-1-1 of the rib plate 3. The two rib plates 3 must be parallel to each other according to the rib plate spacing value D1 given in the drawing, and each edge of the rib plate 3 must be completely perpendicular at the corresponding weld end face. The two guide wheel connecting blocks 4 must be arranged parallel to each other according to the rib spacing value D2 given in the drawings. The outer walls of the fork-shaped horizontal cover plate 1-2 and the horizontal plate 2-1 are coplanar, and the distance between them and the outer wall of the guide wheel connecting block 4 is the value D3 given in the drawings.

[0003] Due to the high precision requirements of subsequent welding and CNC machining processes, the required error in the assembly process of the rail passenger car bogie guide wheel assembly is 0. Any deviation will cause dimensional errors in the subsequent CNC machining, resulting in scrapped workpieces. The existing assembly method for the bogie guide wheel assembly is to manually draw lines according to well-known methods in the field of mechanical processing. The operator then places the various components of the bogie guide wheel mechanism in a given order on the drawn dimension lines for assembly and welding. The operator then performs re-measurements to confirm whether the dimensions in all directions meet the requirements of the drawings.

[0004] Since human errors are inevitable during manual assembly, measurement and line drawing deviations or assembly position and posture deviations often occur during mass production. In particular, all the edges of the right-angled trapezoid of the rib plate 3 are respectively provided with welding chamfers, resulting in narrow and sharp edges, making it difficult to position it vertically with adjacent components. It is neither convenient to align nor to measure and adjust, resulting in the inability to guarantee assembly accuracy and an extremely high rework rate, which not only increases production costs but also increases the labor intensity of operators, resulting in low work efficiency and seriously restricting the improvement of production benefits. To this end, we continue to develop a welding assembly auxiliary tooling suitable for the guide wheel assembly of rail vehicle bogies to overcome the above problems. Summary of the Invention

[0005] In order to solve the technical problem that the existing rail passenger car bogie guide wheel assembly is manually assembled by the operator by drawing lines, measurement and drawing deviations or assembly position and posture deviations often occur due to the existence of uneliminate human errors, especially the right-angled trapezoid on the rib plate has welding chamfers on each side line, which makes it difficult to vertically position the narrow and sharp component with its adjacent components, and is neither convenient for alignment nor for measurement and adjustment, resulting in the inability to guarantee the assembly accuracy and an extremely high rework rate, which not only increases the production cost but also increases the labor intensity of the operator, resulting in low work efficiency and seriously restricting the improvement of production benefits, the present invention provides a rail passenger car bogie guide wheel assembly tool.

[0006] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0007] A rail passenger car bogie guide wheel assembly tooling is characterized in that: the tooling includes a base plate, a multi-component coplanar positioning baffle, an inner side plate horizontal support platform, two outer side plates and a guide wheel connecting block positioning baffle, a guide wheel connecting block transverse tightening screw mechanism, two rib plate positioning baffles, a rib plate transverse tightening screw mechanism, a guide wheel connecting block spacing positioning block, and a rib plate spacing positioning block, the base plate is rectangular, the multi-component coplanar positioning baffle and the inner side plate horizontal support platform are both vertically fixed to the upper end surface of the base plate, and the multi-component coplanar positioning baffle is adjacent to and parallel to a short side of the base plate;

[0008] The two outer plates and the guide wheel connecting block positioning baffle, the guide wheel connecting block transverse tightening screw mechanism, the two rib plate positioning baffles and the rib plate transverse tightening screw mechanism are all vertically fixed to the upper end surface of the base plate, and the inner plate horizontal support platform is fixed between the long side center line of the base plate and the multi-component coplanar positioning baffle; the guide wheel connecting block transverse tightening screw mechanism is located on one side of the inner plate horizontal support platform and the axis of the guide wheel connecting block transverse tightening screw mechanism screw is parallel to the end surface of the multi-component coplanar positioning baffle; the two outer plates and the guide wheel connecting block positioning baffles are located On the other side of the inner plate horizontal support platform, the guide wheel connecting block transverse tightening screw mechanism, the two outer plates and the guide wheel connecting block positioning baffles respectively constitute a guide wheel connecting block plate transverse positioning mechanism; the rib plate transverse tightening screw mechanism is located on one side of the inner plate horizontal support platform and the axis of its screw is parallel to the axis of the screw of the guide wheel connecting block transverse tightening screw mechanism; the two rib plate positioning baffles are both located on the other side of the inner plate horizontal support platform, and the two rib plate positioning baffles respectively constitute a rib plate transverse positioning mechanism with the rib plate transverse tightening screw mechanism;

[0009] The guide wheel connection block spacing positioning block and the rib plate spacing positioning block are both rectangular blocks. The guide wheel connection block spacing positioning block is placed on the inner plate horizontal support in a detachable manner and is located between the guide wheel connection block transverse tightening screw mechanism and its corresponding outer plate and the guide wheel connection block positioning baffle; the rib plate spacing positioning block is placed on the base plate in a detachable manner and is located between the two rib plate positioning baffles and their corresponding rib plate transverse tightening screw mechanisms.

[0010] The beneficial effects of the present invention are as follows: the dimension chain design of each component of the guide wheel assembly of the railway passenger car bogie is designed in accordance with the dimension parameters of the original drawing of the guide wheel assembly, and the distance value H4 from the upper end face of the side panel horizontal support to the upper end face of the base plate is equal to H2, so that the horizontal plate on the inner side panel can be placed on the upper end face of the inner side panel horizontal support and the lower edge of the vertical plate on the inner side panel is supported on the base plate; the width value d2 of the guide wheel connection block spacing positioning block is used to ensure that the spacing value of the two guide wheel connection blocks meets the spacing value D2 given in the drawing. And the width value d1 of the rib plate spacing positioning block is used to ensure the spacing value D1 given in the drawing of the two rib plates respectively. The multi-component coplanar positioning baffle is used to ensure that the front end face of the horizontal plate, the front end face of the fork-shaped horizontal cover plate and the front end faces of the two guide wheel connection blocks are strictly coplanar according to the relative position relationship given in the drawing. In the structural design of the positioning baffle of the outer plate and the guide wheel connecting block, the end faces of the first baffle and the third baffle are coplanar, and the horizontal distance value D4 from the second baffle to the first baffle is equal to D3; the vertical height value from the lower edge of the horizontal rectangular block to the bottom of the horizontal positioning baffle of the inner plate is H8, and H4+k2≤H8≤H4+H6; the vertical height value from the upper edge of the horizontal rectangular block to the horizontal positioning baffle of the inner plate is H8, and H4+k2≤H8≤H4+H6; the upper end face of the fork-shaped cover positioning plate, the upper end of the fork-shaped cover positioning plate The vertical height from the surface to the bottom of the inner side panel's transverse positioning plate baffle is H10, with H1 ≤ H10; the height difference from the upper end surface of the fork-shaped cover plate positioning plate to the upper edge of the transverse rectangular block is H9, with H10-H7-k1 ≤ H9. The combined design of the aforementioned dimension chains ensures that when the combination of the two guide wheel connecting blocks and the guide wheel connecting block spacing positioning blocks is clamped using the guide wheel connecting block plate transverse positioning mechanism, the relative positional relationships of the two guide wheel connecting blocks to the forked horizontal cover plate and the horizontal plate meet the position requirements specified in the drawings. Similarly, other structural dimension chain designs for the outer side panels and guide wheel connecting block positioning baffles can also be used to achieve transverse positioning of the side walls of the forked horizontal cover plate and the outer side walls of the horizontal plate. The rib plate transverse positioning mechanism, consisting of the two rib plate positioning baffles and the rib plate transverse tightening screw mechanism, is used to precisely position the two rib plates in the posture and position specified in the drawings, in conjunction with the rib plate spacing positioning blocks.

[0011] The structural features of the assembly tooling of the present invention are novel in conception and sophisticated in design. Without the aid of any other form of installation or removal tools, only one operator can independently complete the precise assembly positioning and preliminary welding fixation of the overall structural components of the bogie guide wheels of the rail vehicle. After replacing the traditional manual assembly process with this tooling, the operational stability and reliability of the bogie mounting seat during assembly are guaranteed, the accuracy is greatly improved, the production quality is guaranteed, and the labor intensity and skill threshold of the operator are significantly reduced, effectively saving labor and production costs. While achieving a zero rework rate, the production efficiency can also be increased by 5 to 10 times.

[0012] In addition, the bogie guide wheel assembly tooling has the advantages of simple and practical structure, easy operation, low cost, and easy promotion and popularization. BRIEF DESCRIPTION OF THE DRAWINGS
