Description

Technical Field

[0001] The utility model relates to mechanical workpiece cleaning, and in particular to a fixture for cleaning and drying the inner cavity of a workpiece. The fixture is placed in a sealed device that prevents liquid splashing and is used in combination with a pressure pump. Background Art

[0002] With increasing customer demands for product cleanliness, and the frequent occurrence of quality incidents due to substandard product cleanliness, this has triggered strong user reactions. Currently, cleaning workpieces with internal cavities (such as fuel injection pump bodies, speed regulator housings, or servo oil pump housings, which have numerous channels and are made of cast iron) is primarily done manually. This not only fails to meet cleanliness requirements but is also inefficient. Therefore, a device suitable for cleaning workpiece cavities is needed.

[0003] For example, CN 212525280U discloses a "workpiece inner cavity cleaning device," which includes a support member, a gas source member, an air jet member, and a conveying member. The support member includes a horizontal support portion and a vertical support portion; the gas source member includes a gas pipeline connected to a gas source and extending through the horizontal support portion; the air jet member extends through the horizontal support portion and is connected to the gas pipeline to eject the gas within the pipeline; the conveying member has its starting end sleeved on the air jet member and sealed to the horizontal support portion, while its terminal end extends through the vertical support portion and is used to deliver gas to the workpiece to be cleaned. The conveying member can rotate the gas provided by the gas source to fully cover the surface of the workpiece's inner cavity, preventing any areas of the workpiece from being missed and improving the cleaning effect.

[0004] Another example is the "casting cavity cleaning device with a brushing mechanism" disclosed in CN 211679028U, which includes a base and a connecting plate. A rectangular opening is provided on the top of the connecting plate. A first slider is provided on the top of the rectangular opening. The first slider is sleeved on the outer wall of the first screw. The left end of the first screw is fixedly connected to the output end of the first motor. The back of the first slider is hinged to the front of the first push rod and to the back of the cylindrical block. The top of the connecting plate is fixedly connected to the bottom of the water tank. A hydraulic pump is provided inside the water tank. The water outlet of the hydraulic pump is connected to one end of the telescopic hose, and the other side of the nozzle penetrates the inner wall of the cylindrical block. This casting cavity cleaning device with a brushing mechanism simultaneously controls the first motor and the second motor to make the bristles and nozzle form an up and down reciprocating motion along with the cylinder. By starting the hydraulic pump, water is sprayed out from the nozzle, and the casting cavity is fully cleaned by the bristles.

[0005] The technical solutions disclosed in the above two patent documents are both beneficial attempts in the relevant technical field. However, there is still a need for further improvement. Utility Model Content

[0007] The utility model describes a fixture for cleaning and drying the inner cavity of a workpiece, comprising a base, a bearing seat fixedly connected to the base, a plane bearing connected to the bearing seat and a rotating disk connected to the plane bearing; a vertical washing and blowing channel is provided in the center of the upper part of the base, a liquid inlet channel communicating with the washing and blowing channel is provided on one side of the middle part, and the mouth of the liquid inlet channel is provided with a liquid inlet joint; a through hole coaxial with the washing and blowing channel is provided in the center of the bearing seat, and a through hole coaxial with the washing and blowing channel is also provided in the center of the rotating disk; it also includes a nozzle, the upper end of which is connected to the nozzle, and the lower end passes through the through hole of the rotating disk, the center of the plane bearing and the through hole of the bearing seat in sequence and is connected to the washing and blowing channel of the base; the nozzle is provided with a spray outlet.

[0008] Furthermore, an air inlet channel communicating with the washing and blowing channel is provided on the other side of the middle portion of the base, and an air inlet interface is provided at the mouth of the air inlet channel.

[0009] Furthermore, the upper end of the nozzle is threadably connected to the nozzle head, and the height of the nozzle head extending from the rotating disk can be changed by rotating the nozzle head to adapt to cleaning workpieces with different inner cavity heights.

[0010] Furthermore, the nozzle is provided with a nozzle, and the nozzle is in the shape of an elongated rectangle.

[0011] Furthermore, the width of the nozzle outlet is 2 mm and the length is 80 mm.

[0012] Furthermore, an inner stop is provided on the edge of the upper side of the bearing seat, and the outer circle of the lower support of the plane bearing is fitted and connected with the inner stop on the upper side of the bearing seat.

[0013] Furthermore, an outer stop is provided near the edge of the bottom of the rotating disk, and the inner circle of the upper support of the plane bearing is matched with the outer stop on the bottom of the rotating disk, so that the rotating disk can rotate.

[0014] Advantages of this utility model:

[0015] Since the utility model is provided with the cleaning and drying structure, the inner cavity of the workpiece can be cleaned and rinsed in 360 degrees, and the inner cavity of the workpiece can also be dried in 360 degrees.
