Embodiment Construction
[0025] Below in conjunction with accompanying drawing, the present invention will be further described:
[0026] Figure 1 to Figure 2 Shown is a cleaning device for the air hole of a steering gear rack, including a support 1 and a high-pressure water jet cleaning device 2 . The workpiece rack 5 to be cleaned is placed on the left and right support plates of the support 1 , and the high-pressure water jet cleaning device 2 is arranged on the guide rail 11 of the support 1 . The longitudinal position of the high-pressure water spray cleaning device 2 on the guide rail 11 of the support 1 can be adjusted by adjusting the screw 3 of the longitudinal adjustment device, that is, the left and right positions; The angle by which the direction's axis is rotated.
[0027] The support 1 includes two guide rails 11 parallel to each other and a left support plate 12, a left baffle plate 14, a right baffle plate 15, and a right support plate 13, which are connected in series on the guide...

The invention relates to a cleaning device and method for steering engine rack ventilation holes. The cleaning device comprises a support (1) and a high-pressure water spraying cleaning device (2). The cleaning device is characterized by further comprising a longitudinal adjusting device and an angle adjusting device. The longitudinal adjusting device adjusts the longitudinal position of the high-pressure water spraying cleaning device (2) on the support (1). The angle adjusting device adjusts the angle of the high-pressure water spraying cleaning device (2) to rotate around a shaft in the front and back direction. The high-pressure water spraying cleaning device (2) comprises rotating spray heads (21), hose nozzles (22), a water storage tank (23) and a base (24). The rotating spray heads (21) are arranged on the upper end face of the water storage tank (23). The hose nozzles (22) are arranged on the rotating spray heads (21). The multiple rotating spray heads (21) and the multiple hose nozzles (22) correspond one to one. The water storage tank (23) is arranged on the base (24) in a rotating manner. The base (24) is arranged on a guide rail (11) in a sliding manner. The cleaning device improves the cleaning quality of the rack ventilation holes and the working efficiency.
Description
technical field [0001] The invention belongs to the technical field of automobile production and manufacturing, and in particular relates to a cleaning device for a vent hole of a steering gear rack. Background technique [0002] At present, the steering system in the car industry mostly adopts the rack and pinion hydraulic power steering machine. There are vent holes with a long depth to maintain a stable and unobstructed air pressure at both ends of the rack. [0003] Since the rack-and-pinion hydraulic power steering machine uses hydraulic oil as the power assist, it has certain requirements on the sealing and cleanliness of the product. During the process of machining the vent hole on the rack, impurities such as iron filings stay in the inner wall of the hole. The falling of impurities will lead to the reduction of the cleanliness and sealing of the steering gear, resulting in oil leakage and abnormal noise of the steering gear assembly in the later stage. In the curr...
