Description

Technical Field

[0001] This utility model relates to the field of locomotive drive component maintenance technology, specifically a tooling for cleaning and flaw detection of locomotive drive gears. Background Technology

[0002] During the maintenance of electric locomotive drive units, driven gears require cleaning and flaw detection. The cleaning process often involves multiple flipping of the parts, leading to incomplete cleaning, incomplete flaw detection, and low efficiency. In existing HXD3B and HXD3D electric locomotive drive units, after entering the C6 maintenance phase, the driven gear is disassembled and placed horizontally before being cleaned with a high-pressure water gun and cleaning agent. After cleaning, the gear is flipped over for cleaning of the other side. Flaw detection is also performed by flipping twice, and after flaw detection, the gear is flipped twice again before cleaning the surface with magnetic suspension or contrast agent. This process of flipping the gear multiple times during continuous flaw detection results in low automation, requiring frequent manual intervention and adjustments, consuming significant time and manpower. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a tooling for cleaning and flaw detection of locomotive gears, which overcomes the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tooling for cleaning and flaw detection of locomotive gears, including a support frame and a rotating shaft. The support frame includes a base frame and two rectangular frames fixed on the base frame and spaced apart. Each rectangular frame has two spaced rubber-coated rollers and a motor at its top. One end of the rotating shaft of the two rubber-coated rollers has a pulley, and the two pulleys are connected by a belt. One of the pulleys is connected to the motor, and the motor is fixed on the rectangular frame.

[0005] Near its two ends, the rotating shaft can be placed between two rubber-coated rollers located on the same rectangular frame. The surface of the rotating shaft is in contact with the rubber-coated rollers, and a nylon sleeve is fitted on the rotating shaft.

[0006] Optionally, the base frame has casters at its bottom.

[0007] Optionally, a locking mechanism is provided on the caster wheel.

[0008] The advantages and positive effects of this utility model are: reasonable structural design, which can realize automatic rotation of the teeth, facilitates automated cleaning and flaw detection, is simple to operate, and is easy to move. It not only ensures that the teeth are cleaned without omission, but also improves the efficiency of flaw detection. Attached Figure Description

[0011] The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, 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, and therefore should not be construed as a limitation of the present invention. In the description of the present invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood through specific circumstances.

[0012] like Figure 1 As shown, this utility model provides a tooling for cleaning and flaw detection of locomotive gears, including a support frame 1 and a rotating shaft 4. The support frame 1 includes a base frame and two rectangular frames fixed on the base frame and spaced apart. Each rectangular frame has two spaced rubber-coated rollers 3 and a motor (not shown) at its top. One end of the rotating shaft of the two rubber-coated rollers 3 has a pulley 3-1. The two pulleys 3-1 are connected by a belt. One of the pulleys 3-1 is connected to the motor, and the motor is fixed on the rectangular frame.

[0013] Near its two ends, the rotating shaft 4 can be placed between two rubber-coated rollers 3 located on the same rectangular frame. The surface of the rotating shaft 4 is in contact with the rubber-coated rollers 3, and a nylon sleeve 5 is fitted on the rotating shaft 4.

[0014] The bottom of the base frame has casters with locking mechanisms (not shown in the figure).

[0015] The support frame 1 in the above structure is mainly made of high-strength alloy material. It has multiple casters with braking devices at its bottom, facilitating the movement of the entire fixture and ensuring stability when a fixed position is required. The frame structure allows the toothed gear 6 to be placed vertically. The height of the support frame 1 is larger than the diameter of the toothed gear 6, so the support frame 1 is suspended in mid-air when the toothed gear 6 is inserted, not in contact with its base. The rotating shaft 4 is a high-strength circular tube with the same length as the width of the base of the support frame 1, and a nylon sleeve 5 is fitted inside the tube. In use, the rotating shaft 4 passes through the middle hole of the driven gear 6. The driven gear 6 is lifted onto the support frame 1 using a lifting tool. Near both ends of the rotating shaft 4, it contacts four rubber-coated rollers 3, which support the rotating shaft 4. By adjusting the motor speed, the rubber-coated rollers 3 drive the rotating shaft 4 to rotate. The nylon sleeve 5 on the rotating shaft 4 drives the driven gear 6 to rotate through friction with the inner wall of the driven gear 6. This fixture is used in conjunction with a cleaning and moving flaw detector. When cleaning the driven gear 6, a high-pressure water gun can be used to clean the oil stains, magnetic suspension, or contrast agent on the surface of the driven gear 6. As the driven gear 6 rotates on the fixture, the high-pressure water gun probe can clean the driven gear thoroughly without any blind spots. When flaw detecting the driven gear 6, the magnetic particle flaw detector is started, and the motor drives the workpiece to rotate. The flaw detector probe performs flaw detection on the driven gear. If an abnormality is found during the flaw detection process, the motor rotation is stopped. After the operation is completed, use a lifting device to lift the tooth out of the cleaning and flaw detection equipment. After pulling the rotating shaft 4 out of the center hole of the tooth 6, lift the next tooth 6, pass it through the center hole of the tooth 6, and continue the next operation. Because the flaw detection of the tooth 6 is magnetic particle flaw detection, the entire part of the tooth 6 is flaw-detected during the operation. Therefore, using a mobile flaw detector is simple, lightweight, and easy to operate.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
