Description

Technical Field

[0001] The invention belongs to the field of locomotive manufacturing, and more specifically, relates to a bogie frame assembly tool. Background Art

[0002] The bogie frame is welded from metal parts such as steel plates, steel pipes, forgings, castings, etc. It is mainly composed of crossbeams and side beams, and the process quality control requirements are strict. The assembly error during the frame welding process affects the size of the finished frame. The frame size affects whether the frame processing has sufficient processing volume or whether it will be overcut, and also affects the assembly of the bogie. The frame assembly size is mainly guaranteed by tooling, and the assembly method also affects the frame assembly accuracy.

[0003] See also Figure 1 The state of the frame when the bogie is placed upright is the frame upright state, and vice versa, the state of the frame when the bogie is placed inverted is the frame inverted state. The existing frame assembly process is: using the crossbeam assembly tool and the side beam assembly tool to respectively assemble the crossbeam assembly and the longitudinal beam assembly, and then assemble the crossbeam assembly and the longitudinal beam assembly to obtain the bogie frame.

[0004] However, when the crossbeam assembly is installed using the crossbeam assembly tool, it is installed in an inverted state (i.e., inverted installation), and when the side beam assembly is installed using the side beam assembly tool, it is installed in an upright state (i.e., upright installation), and when the crossbeam assembly and the longitudinal beam assembly are assembled to obtain the bogie frame, they are also installed in an upright state (i.e., upright installation). This brings certain difficulties to the frame assembly. Since there is no unified positioning in the entire assembly process, after assembling the crossbeam assembly and the side beam assembly, the crossbeam assembly and the side beam assembly need to be moved to the platform separately, and the crossbeam assembly and the side beam assembly need to be re-marked and positioned manually. Manual marking and positioning may increase errors and make the operation cumbersome. Summary of the invention

[0005] The object of the present invention is to provide a bogie frame assembly tool, aiming to solve or at least to a certain extent improve the technical problems existing in the existing bogie frame assembly process that the crossbeam assembly and the side beam assembly need to be marked and positioned, and the operation is cumbersome.

[0050] See also Figures 6 to 13 , an embodiment of the bogie frame assembly tool provided by the present invention is now described. The bogie frame assembly tool is used to position and assemble the crossbeam assembly and the side beam assembly to obtain the bogie frame. The bogie frame assembly tool includes a frame 100, a crossbeam accompanying clamping mechanism 200, a positioning assembly 300, a side beam assembly mechanism 400, an axial clamping mechanism 800 and an axial positioning moving mechanism 500.

[0051] Among them, the beam accompanying clamping mechanism 200 is installed on the frame 100, and is used to position and clamp the beam assembly 600, and the beam assembly 600 is assembled on the beam accompanying clamping mechanism 200. Specifically, after the beam is positioned and clamped on the beam accompanying clamping mechanism 200, the accessories in the beam assembly are positioned (and clamped) using the beam assembly tooling, and the assembly of the beam assembly 600 is completed on the beam accompanying clamping mechanism 200.

[0052] The side beam assembly mechanism 400 is installed on the axial positioning and moving mechanism 500, and is used for positioning and clamping the side beam assembly 700, and the side beam assembly 700 is assembled on the side beam assembly mechanism 400. Specifically, after the side beam 710 is positioned and clamped on the side beam assembly mechanism 400, the accessories in the side beam assembly are positioned (and clamped) by using the side beam assembly tooling, and the assembly of the side beam assembly 700 is completed on the side beam assembly mechanism 400.

[0053] The positioning assembly 300 is used to position the beam accompanying clamping mechanism 200 to a preset position on the frame 100 . In this way, the assembled beam assembly 600 is actually positioned and installed to the preset position on the frame 100 .

[0054] The axial positioning moving mechanism 500 is installed on the frame 100, and is used to drive the side beam assembly mechanism 400 to move along the axial direction of the cross beam, and move and position the side beam assembly 700 to a preset installation position relative to the cross beam assembly 600. At this preset installation position, the cross beam is inserted into the insertion hole of the side beam 710, and the side beam assembly 700 and the cross beam assembly 600 complete the positioning work, and there is no need to perform complex manual marking positioning on the side beam assembly 700 and the cross beam assembly 600 respectively as in the prior art, which simplifies the positioning operation of the side beam assembly 700 and the cross beam assembly 600. In addition, the axial positioning moving mechanism 500 is used to move and position the huge side beam assembly 700, avoiding the heavy operation of manually carrying the side beam assembly 700, and the positioning of the side beam assembly 700 and the cross beam assembly 600 is more accurate. At the same time, by using the bogie frame assembly tool provided in the embodiment of the present invention, the crossbeam assembly 600, the side beam assembly 700 and the frame can be assembled in the normal or reverse manner, reducing the flipping operation of the crossbeam assembly 600 and the side beam assembly 700 during the assembly process.

[0055] The axial clamping mechanism 800 is installed on the frame 100. The assembled side beam assembly 700 and the assembled cross beam assembly 600 (i.e., the relative positioning of the side beam assembly mechanism 400 and the cross beam accompanying clamping mechanism 200) are positioned by the axial positioning moving mechanism 500, and the axial clamping mechanism 800 is used to clamp and fix the side beam assembly 700 after being positioned relative to the cross beam assembly 600, so as to facilitate subsequent operations.

[0056] After completing the positioning and clamping of the side beam assembly 700 and the cross beam assembly 600, the operator can assemble and connect the side beam assembly 700 and the cross beam assembly 600 using the bogie frame assembly tooling provided in the embodiment of the present invention, and then obtain the bogie frame.

[0057] Compared with the prior art, the bogie frame assembly tool provided in the embodiment of the present invention realizes the positioning and assembly of the crossbeam assembly and the side beam assembly by providing a crossbeam accompanying clamping mechanism for positioning and clamping the crossbeam assembly and a side beam assembly mechanism for positioning and clamping the side beam assembly, and by providing a positioning assembly for positioning the crossbeam accompanying clamping mechanism and an axial positioning and moving mechanism for driving the side beam assembly mechanism to move and position the side beam assembly to a preset installation position relative to the crossbeam assembly, thereby avoiding complicated manual marking and positioning and cumbersome and heavy handling operations.

[0058] See also Figures 6 to 13 As a specific implementation of the bogie frame assembly tool provided by the present invention, the crossbeam assembly 600 is in a reverse assembly form on the crossbeam accompanying clamping mechanism 200; the side beam assembly 700 is in a reverse assembly form on the side beam assembly mechanism; the assembly of the frame (the assembly connection of the crossbeam assembly 600 and the side beam assembly 700 on the bogie frame assembly tool provided in the embodiment of the present invention) is also in a reverse assembly form.

[0059] See also Figures 6 to 8 and Figures 10 to 13 As a specific embodiment of the bogie frame assembly tooling provided by the present invention, the beam accompanying clamping mechanism 200 includes a first clamping block 210, a second clamping block 220 for mounting on the frame 100, and a locking assembly. The second clamping block 220 is provided with a V-shaped groove 221 for positioning the beam. The locking assembly enables the first clamping block 210 to clamp and fix the positioned beam on the second clamping block 220 (in the V-shaped groove 221). Of course, the beam assembly 600 usually includes two sets of parallel beams, so the V-shaped grooves 221 on the second clamping block 220 also have two parallel and spaced apart. After the beam is placed in the V-shaped groove 221, the beam is positioned in two degrees of freedom. The axial positioning of the beam in the beam accompanying clamping mechanism 200 (or in the V-shaped groove 221) can be ensured by marking (on the beam) or other tooling. The axial positioning of the beam is very easy to achieve in the prior art and will not be repeated here. The locking assembly and the first clamping block 210 fix the positioned crossbeam to prevent the crossbeam from moving during the subsequent assembly process.

[0060] After the crossbeam is positioned and clamped on the crossbeam accompanying clamping mechanism 200, the crossbeam assembly tooling can be used to connect and assemble the crossbeam accessories to obtain the crossbeam assembly 600. Of course, it should be understood here that before assembling the crossbeam assembly, the crossbeam accompanying clamping mechanism 200 can be positioned and installed on the frame 100, or after assembling the crossbeam assembly 600, the crossbeam accompanying clamping mechanism 200 can be positioned and installed on the frame 100.

[0061] See also Figures 10 to 12As a specific embodiment of the bogie frame assembly tool provided by the present invention, the bottom surface of the second clamping block 220 abuts against the frame 100, and the second clamping block 220 can be installed on the frame 100 by threaded connection, tight connection, etc. The positioning assembly 300 includes a first positioning round pin 310, a first positioning diamond pin 330, a first round hole 320 inserted and positioned with the first positioning round pin 310, and a second round hole inserted and positioned with the first positioning diamond pin 330. Through the insertion and positioning of the two groups of pin holes and the abutment and positioning of the bottom surface of the second clamping block 220 with the frame 100, the purpose of positioning the second clamping block 220 (i.e., the beam accompanying clamping mechanism 200) to the preset position on the frame 100 is achieved. In the two groups of pin hole insertion and positioning, one group adopts round pins and round holes for positioning, and the other group adopts diamond pins 330 and round holes for positioning, so as to avoid the problem of over-positioning.

[0062] The first positioning round pin 310 and the first positioning diamond pin 330 are disposed on one of the second clamping block 220 or the frame 100 , and the first round hole 320 and the second round hole are disposed on the other of the second clamping block 220 or the frame 100 .

[0063] See also Figures 7 and 8 and Figures 10 to 12 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the frame 100 includes a base plate 110 and an adapter plate 120 fixed on the base plate 110, a first positioning round pin 310 and a first positioning diamond pin 330 are arranged on (the bottom surface of) the second clamping block 220, a first circular hole 320 and a second circular hole are arranged on the adapter plate 120, and the bottom surface of the second clamping block 220 abuts against the top surface of the adapter plate 120.

[0064] The second clamping block is provided with a first extending plate 222, and the adapter plate 120 is provided with a second extending plate 121. There is a certain gap between the second extending plate 121 and the base plate 110, and the first extending plate 222 and the second extending plate 121 are in contact with each other. The first extending plate 222 and the second extending plate 121 are provided with a first notch and a second notch, respectively, and the second clamping block 220 and the adapter plate 120 are fixedly connected by a first threaded tightening assembly penetrating the first notch and the second notch.

[0065] See also Figures 6 to 8 and Figures 10 to 13 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the locking assembly includes a first stud 230 fixed on the second clamping block 220 and a first nut 240 threadedly connected to the first stud 230, and the first clamping block 210 is provided with a first through hole for the first stud 230 to pass through.

[0066] The first nut 240 is located on a side of the first clamping block 210 away from the second clamping block 220, and the first nut 240 is threadedly connected to the portion of the first stud 230 extending out of the first clamping block 210, so that when the first nut 240 is tightened, the first nut 240 will abut against the first clamping block 210, and the first clamping block 210 will clamp the crossbeam on the second clamping block 220 (in the V-groove 221).

[0067] See also Fig.13 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the locking assembly also includes a lifting ring 250, and the lifting ring 250 is provided with a threaded hole portion for threaded connection with the first stud 230. In the prior art, since the crossbeam is relatively heavy, the operator needs to use the overhead crane hook to hook the crossbeam to move the crossbeam assembly (or the assembled bogie frame), so that the hook may scratch the crossbeam. In this embodiment, by providing the lifting ring 250, the operator can move the crossbeam assembly (or the assembled bogie frame) by hooking the lifting ring 250 and using the mobile crossbeam accompanying clamping mechanism 200 (or the bogie frame assembly tool provided by the embodiment of the present invention).

[0068] See also Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the side beam assembly mechanism 400 includes a base 410 installed on the axial positioning and moving mechanism 500, a second positioning round pin 420 fixed on the base 410, an axial positioning member 430, a support member 440 for supporting and positioning the side beam 710 in the vertical direction, and a vertical locking member 460. The axial positioning member 430, the support member 440 and the vertical locking member 460 are installed on the base 410. In order to support and position the side beam 710 in the vertical direction, the support member 440 is located at the lower part of the reversed side beam 710.

[0069] The second positioning round pin 420 is used for inserting and positioning with the vertical hole of the empty spring guide column on the side beam 710. The vertical hole of the empty spring guide column is specifically located on the side beam 710. The vertical hole of the empty spring guide column and the second positioning round pin 420 form a pin hole for inserting and positioning. The axial positioning member 430 is used for abutting and positioning with the process member 720 on the side beam 710 in the axial direction of the cross beam. In this way, the axial positioning member 430, the second positioning round pin 420 and the support member 440 form a three-degree-of-freedom positioning for the side beam 710.

[0070] In the prior art, three blocks are used to limit the three degrees of freedom of the side beam 710, but one of the positioning surfaces of the side beam 710 is a plastic correction surface, which is not flat and prone to positioning errors. In this embodiment, the plastic correction surface is no longer used to position the side beam 710. Instead, the second positioning round pin 420 and the vertical hole of the empty spring guide column are used to position one degree of freedom, which makes the positioning more accurate.

[0071] The vertical locking member 460 is used to abut the side beam 710 so that the side beam 710 is abutted and fixed with the support member 440 in the vertical direction. After the side beam 710 is positioned on the side beam assembly mechanism 400 through the axial positioning member 430, the second positioning round pin 420 and the support member 440, the side beam 710 is clamped and fixed on the side beam assembly mechanism 400 through the vertical locking member 460; then, the side beam assembly tool is used to position and assemble the side beam accessories, and finally the side beam assembly 700 is obtained.

[0072] See also Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 As a specific implementation of the bogie frame assembly tooling provided by the present invention, the second positioning round pin 420 is directly fixed on the support member 440, the upper top surface of the support member 440 is used to abut against the side beam 710, and the second positioning round pin 420 protrudes upward from the upper top surface of the support member 440.

[0073] See also Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 As a specific implementation of the bogie frame assembly tool provided by the present invention, the side beam assembly mechanism 400 also includes a gantry 470, and the gantry 470 is fixed on the base 410.

[0074] As a specific implementation of the bogie frame assembly tool provided by the present invention, the axial clamping mechanism 800 and the vertical locking member 460 can be structures such as quick clamps and spiral clamps respectively.

[0075] See also Figure 2 , Figure 3 , Figure 7 and Fig. 9As a specific embodiment of the bogie frame assembly tool provided by the present invention, the axial positioning member 430 is provided with a first positioning vertical surface 432, and the process member 720 has a second positioning vertical surface 7212. The first positioning vertical surface 432 and the second positioning vertical surface 7212 are both planes in the vertical direction (at the same time, the normal directions of the first positioning vertical surface 432 and the second positioning vertical surface 7212 are parallel to or in the same direction as the axial direction of the crossbeam). When the side beam 710 is positioned, the first positioning vertical surface 432 and the second positioning vertical surface 7212 abut against each other in the axial direction of the crossbeam to form the positioning of the side beam 710 in the axial direction of the crossbeam.

[0076] See also Fig. 9 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the axial positioning member 430 also has a first positioning plane 431 and a second positioning plane 433. The first positioning plane 431 and the second positioning plane 433 are both planes parallel to the horizontal plane, and the first positioning plane 431 is higher than the second positioning plane 433. The first positioning vertical surface 432 is connected to the first positioning plane 431 and the second positioning plane 433 respectively, and the first positioning plane 431, the first positioning vertical surface 432 and the second positioning plane 433 form a step structure.

[0077] See also Figures 6 to 13 As a specific embodiment of the bogie frame assembly tool provided by the present invention, since the axial direction of the crossbeam is long, there are two sets of crossbeam accompanying clamping mechanisms 200, and the two sets of crossbeam accompanying clamping mechanisms 200 are arranged at intervals along the axial direction of the crossbeam. Correspondingly, since each set of crossbeam accompanying clamping mechanisms 200 corresponds to a set of positioning components 300, there are also two sets of positioning components 300. There are also two sets of side beams 710 in the bogie frame, so there must be at least two sets of side beam assembly mechanisms 400 and axial positioning and moving mechanisms 500.

[0078] See also Figures 6 to 13 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the axial positioning movement mechanism 500 includes a slide rail 510, a sleeve 520 slidingly matched on the slide rail 510, and a sleeve positioning member (not shown), and the side beam assembly mechanism 400 (base 410) is installed on the sleeve 520.

[0079] The sleeve positioning member is fixed on the slide rail 510 and is used to abut against the sleeve 520. When the side beam assembly 700 is initially installed on the side beam assembly mechanism 400, there is a certain interval between the sleeve 520 and the sleeve positioning member. After the side beam assembly 700 is assembled, when the operator moves the sleeve 520 on the slide rail 510, when the sleeve 520 abuts against the sleeve positioning member, the positioning of the side beam assembly 700 relative to the cross beam assembly 600 is completed (that is, the side beam assembly 700 completes the axial positioning of the cross beam relative to the cross beam assembly 600, and the positioning of other degrees of freedom has been completed by the cross beam accompanying clamping mechanism 200, the positioning assembly 300 and the side beam assembly mechanism 400), that is, the side beam assembly 700 is moved and positioned to a preset installation position relative to the cross beam assembly 600, and the cross beam is inserted into the insertion hole of the side beam 710. After the side beam assembly 700 is axially positioned relative to the cross beam assembly 600, the operator can clamp and fix the side beam assembly 700 (or the side beam assembly mechanism 400) through the axial clamping mechanism 800. Specifically, the axial clamping mechanism 800 is installed on the frame 100, and the output end of the axial clamping mechanism 800 abuts against the side beam 710 along the axial direction of the cross beam. Due to the abutment force between the sliding sleeve positioning member and the sliding sleeve 520, the side beam assembly 700 (or the side beam assembly mechanism 400) is finally clamped and fixed relative to the cross beam assembly 600. After that, the side beam assembly 700 and the cross beam assembly 600 can be connected and assembled to form a bogie frame.

[0080] See also Figures 2 to 13 The present invention also provides a bogie frame assembly method, using the above-mentioned bogie frame assembly tool to perform assembly operations, comprising the following steps:

[0081] S100 obtains the crossbeam and the crossbeam accessories, positions and clamps the crossbeam onto the crossbeam accompanying clamping mechanism 200, and assembles the crossbeam assembly 600 using the crossbeam assembly tooling.

[0082] S200 obtains the side beam 710, the process part 720 and the side beam accessories, and fixes the process part 720 to a preset position on the side beam 710 (this preset position can be ensured by marking or tooling). The process part 720 has a stepped structure, and the stepped structure has a first process plane 7211, a second positioning vertical surface 7212 and a second process plane 7213. The second positioning vertical surface 7212 is connected to the first process plane 7211 and the second process plane 7213 respectively. Of course, the second positioning vertical surface 7212 is used to abut and position with the first positioning vertical surface 432 of the axial positioning member 430. The side beam 710 is positioned and clamped to the side beam assembly mechanism 400, and the side beam assembly assembly 700 is obtained by assembling using the side beam assembly tooling.

[0083] S300 uses the axial positioning movement mechanism 500 to drive the side beam assembly mechanism 400 to move along the axial direction of the cross beam, so that the cross beam is inserted into the insertion hole of the side beam 710, and the side beam assembly 700 is moved and positioned to a preset installation position relative to the cross beam assembly 600; the side beam assembly 700 and the cross beam assembly 600 are assembled and connected to obtain a primary bogie frame. At this time, the connected side beam assembly 700 and the cross beam assembly 600 are not the final bogie frame, but the primary bogie frame, because the process part 720 with a stepped structure does not meet the requirements of the drawing and needs further processing.

[0084] S300 removes the primary bogie frame from the bogie frame assembly tooling in the present invention, processes the process piece 720 to remove the stepped structure, obtains the process piece 720' after the stepped structure is removed (at this time, the shape and structure of the process piece 720' after the stepped structure is removed meet the requirements of the drawing, and the previous process piece 720 is larger in size and is mainly used for axial positioning of the crossbeam), and obtains the final bogie frame.

[0085] Compared with the prior art, the bogie frame assembly method provided in the embodiment of the present invention realizes the positioning and assembly of the crossbeam assembly and the side beam assembly by providing a crossbeam accompanying clamping mechanism for positioning and clamping the crossbeam assembly and a side beam assembly mechanism for positioning and clamping the side beam assembly, and by providing a positioning assembly for positioning the crossbeam accompanying clamping mechanism and an axial positioning and moving mechanism for driving the side beam assembly mechanism to move and position the side beam assembly to a preset installation position relative to the crossbeam assembly, thereby avoiding complicated manual marking positioning and cumbersome and heavy handling operations; at the same time, by providing process parts on the side beams and using the process parts for axial positioning of the crossbeams, it is more accurate than the positioning using the shaping and correction surface in the prior art.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
