Description

Technical Field

[0001] This utility model relates to a wheelset assembly / disassembly machine, specifically related to its tooling device. It is used for pressing, unloading, and back-pressure testing of HXD1 wheelsets. Background Technology

[0002] For the pressing, unloading, and back-pressing tests of general train wheelsets, existing loading and unloading machines with movable beams and insert plates can be used. However, for the HXD1 wheelset, the design process requirements do not allow pressing or unloading by pressing the insert plate against the end face of the wheel. Instead, pressing or unloading must be done by clamping the insert plate into the process groove of the wheel hub. Therefore, the aforementioned insert plate type loading and unloading machine cannot be used. However, in order to save on the cost of purchasing new machines, not to increase the footprint of new machines, and not to affect the changes in the production line, a new technical solution must be found to achieve the best of all. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a tooling device for a wheelset assembly / disassembly machine. It can be directly used on existing disassembly / disassembly machines on the production line to realize the assembly / disassembly of HXD1 wheelsets, saving costs, without increasing floor space, and without changing the production line.

[0004] To achieve the above objectives, the technical solution of this utility model is a tooling device for a wheelset assembly and disassembly machine, which consists of two bearing-shaped disassembly blocks; wherein the upper and lower ends of the first disassembly block are provided with guide posts, and the guide posts are provided with positioning grooves, and the guide posts are fixed by set screws; the upper and lower ends of the second disassembly block are provided with guide post holes, and a set handwheel is provided at the corresponding guide post holes, and a stop screw is provided in front of the set handwheel;

[0005] The back of both unloading blocks is equipped with push-pull handles and lifting lugs, and the upper and lower end faces are equipped with inserts and sliding blocks. The inner openings of the two unloading blocks are shaped to match the HXD1 wheel hub.

[0006] The beneficial effects of this utility model are that it can be interchanged with the insert plate of the movable beam, realizing the disassembly and assembly and back pressure test of all wheelsets including the HXD1 wheelset, saving investment, reducing costs, without increasing the footprint, and without changing the production line.

[0023] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] like Figures 1 to 6 As shown, this utility model discloses a tooling device 100 for a wheelset assembly and disassembly machine, which consists of two bearing-shaped disassembly blocks; wherein the upper and lower ends of the disassembly block 1 are provided with guide posts 11, and the guide posts are provided with positioning grooves 12, and the guide posts are fixed by set screws 13; the upper and lower ends of the disassembly block 2 are provided with guide post holes 21, and a set handwheel 22 is provided at the corresponding guide post holes, and a stop screw is provided in front of the set handwheel;

[0025] Both unloading blocks are equipped with push-pull handles 3 and lifting lugs 4 on their backs, and inserts 5 on their upper and lower ends. Each insert has a sliding bolster 6. The inner openings of both unloading blocks are shaped to fit the HXD1 wheel hub. The inserts facilitate insertion into the slots of the movable beam, and the sliding bolsters ensure smooth insertion. The handles facilitate manual push-pull operation.

[0026] The two bearing-shaped retraction blocks operate in an upright position. Retraction block one replaces the insert block in the original movable beam, while retraction block two is hoisted from the outside to the outer opening of the movable beam. During operation, the trolley delivers the wheelset to the center position of the wheelset assembly / disassembly machine and then retracts. The movable beam moves to the designated position, and an oil injection connector is installed on the wheel disc. The wheelset is rotated to a certain angle so that the oil injection connector protrudes from the tooling device opening for easy oil injection. The two retraction blocks are then manually closed and inserted into the retraction groove of the wheel hub. The handwheel is then rotated to secure them. When assembling / disassembling the HXD1 wheelset or performing a back pressure test, the main hydraulic cylinder is activated, and continuous force is applied to one end of the axle to complete the assembly / disassembly.

[0027] The wheelset assembly and disassembly machine uses a movable beam to lift and remove the second unloading block, completing the pressing, unloading, and counter-pressing tests of the wheelset. Then, the two unloading blocks are pulled apart to a certain position (ensuring no interference with other components), and the movable beam is moved to the designated position on the machine tool and stopped.

[0028] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
