Description

Technical Field

[0001] This utility model relates to a sandblasting device for an intermediate shell flow channel. Background Technology

[0002] The intermediate casing flow channel refers to the passageway located inside the intermediate casing of equipment such as turbochargers, used for the flow of gas or liquid. The intermediate casing flow channel plays a crucial role in turbochargers. It is a key component connecting the compressor housing and the turbine housing. Through the design of the flow channel, the smooth flow of gas or liquid within the intermediate casing can be ensured, thereby enabling the turbocharger to operate normally.

[0003] The main function of sandblasting the intermediate shell flow channel is to remove surface contaminants and oxides, and to improve the adhesion of coatings or plating. In addition, sandblasting can improve the surface quality and appearance of the intermediate shell flow channel, eliminating defects such as cracks and burrs, making the flow channel surface smoother and more even, which helps improve the overall performance and reliability of the equipment.

[0004] In existing technologies, due to the curved and winding shape of the intermediate shell flow channel, sandblasting can easily lead to incomplete sandblasting in some areas of the flow channel, resulting in uneven and rough surfaces in some areas. To solve the above technical problems, this invention proposes an intermediate shell flow channel sandblasting device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a sandblasting device for an intermediate shell flow channel.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a sandblasting device for a middle shell flow channel, including a sandblasting machine, wherein a first sandblasting station and a second sandblasting station are provided on the worktable of the sandblasting machine, a first sandblasting pipe is provided on the first sandblasting station for sandblasting one end of the flow channel at the front of the middle shell, a second sandblasting pipe is provided on the second sandblasting station for sandblasting the other opposite end of the flow channel at the front of the middle shell, and a third sandblasting pipe is provided for sandblasting the flow channel at the rear of the middle shell.

[0007] Preferably, the first sandblasting pipe and the second sandblasting pipe are driven to rise and fall by a drive mechanism.

[0008] Preferably, both the first and second sandblasting stations are equipped with a positioning structure with an intermediate shell.

[0009] Preferably, each positioning structure includes a horizontal base plate that is at the same horizontal height as the workbench and is connected to it. A vertical side plate is vertically fixed on the rear side of each horizontal base plate, and a semi-circular pre-positioning groove is provided on the front of each vertical side plate.

[0010] Preferably, inclined side strips are fixed at both ends of the upper surface of the horizontal base plate, and the left and right side strips on the same horizontal base plate form an isosceles trapezoidal structure that is wider at the front and narrower at the back.

[0011] Preferably, the third sandblasting pipe extends upwards from back to front.

[0012] Preferably, the middle of the vertical side plate of the second sandblasting station is provided with a first clearance groove that runs vertically and horizontally, and the third sandblasting pipe extends upward at an angle after passing through the first clearance groove from back to front.

[0013] Preferably, the horizontal base plate has a second clearance groove that runs vertically through the middle.

[0014] Preferably, the sandblasting machine is provided with sandblasting chambers at both the first and second sandblasting stations. The first, second, and third sandblasting pipes and the positioning structure are all located inside the corresponding sandblasting chambers. The bottom of the sandblasting chambers is hollowed out and leads to the sand collection structure of the sandblasting machine.

[0015] Preferably, each of the sandblasting chambers is provided with an entrance / exit at the front, and each entrance / exit is provided with a switch door that is driven to rise and fall by a drive mechanism.

[0016] Compared with existing technologies, this utility model has the following beneficial effects: The intermediate shell flow channel sandblasting device is equipped with first, second, and third sandblasting pipes. The first and second sandblasting pipes are for sandblasting towards the front of the flow channel inside the intermediate shell, and the third sandblasting pipe is for sandblasting towards the rear of the flow channel inside the intermediate shell. This arrangement rationally distributes the sandblasting pipes, ensuring that both the front and rear flow channels inside the intermediate shell have corresponding sandblasting pipes responsible for sandblasting, thus improving the sandblasting effect and efficiency. Furthermore, since the flow channel at the front of the intermediate shell is long and winding, two sandblasting pipes are used. The first sandblasting pipe sprays sand at one end of the flow channel at the front of the intermediate shell, and the second sandblasting pipe sprays sand at the opposite end of the flow channel at the front of the intermediate shell. This two-end sandblasting method makes the sandblasting of the inner front flow channel more complete and thorough, further improving the sandblasting effect and efficiency.

The worktable 1 of the sandblasting machine is provided with a first sandblasting station 2 and a second sandblasting station 3. The first sandblasting station is provided with a first sandblasting pipe 6 for sandblasting one end of the flow channel 5 at the front of the intermediate shell 4. The second sandblasting station is provided with a second sandblasting pipe 7 for sandblasting the other opposite end of the flow channel at the front of the intermediate shell. A third sandblasting pipe 9 is provided for sandblasting the flow channel 8 at the rear of the intermediate shell.

[0029] In this embodiment of the utility model, the first sandblasting pipe and the second sandblasting pipe are respectively driven to rise and fall by a driving mechanism, which is a cylinder.

[0030] In this embodiment of the utility model, both the first sandblasting station and the second sandblasting station are provided with a positioning structure 10 of the intermediate shell.

[0031] In this embodiment of the utility model, the positioning structure includes a horizontal base plate 11 that is at the same horizontal height as the workbench and is connected to it. A vertical side plate 12 is vertically fixed on the rear side of the horizontal base plate, and a semi-circular pre-positioning groove 13 is provided on the front of the vertical side plate.

[0032] In this embodiment of the utility model, inclined side baffles 14 are fixed at both ends of the upper surface of the horizontal base plate, and the left and right side baffles on the same horizontal base plate form an isosceles trapezoidal structure that is wider at the front and narrower at the back.

[0033] In this embodiment of the invention, the minimum spacing between the left and right side baffles on the same horizontal base plate is adapted to the length of the corresponding middle shell end.

[0034] In this embodiment of the utility model, the third sandblasting pipe extends upward at an angle from back to front.

[0035] In this embodiment of the utility model, the vertical side plates of the first and second sandblasting stations are provided with a first clearance groove 15 that runs vertically and horizontally, and the third sandblasting pipe extends upward at an angle after passing through the first clearance groove from back to front.

[0036] In this embodiment of the utility model, a second clearance groove 16 is provided in the middle of the horizontal base plate, which is open from top to bottom, to facilitate the downward flow of sand.

[0037] In this embodiment of the utility model, the sandblasting machine is provided with sandblasting chambers 17 at both the first and second sandblasting stations. The first, second, and third sandblasting pipes and the positioning structure are all installed inside the corresponding sandblasting chambers. The bottom of the sandblasting chamber is hollowed out 20 and leads to the sand collection structure of the sandblasting machine.

[0038] In this embodiment of the utility model, each of the sandblasting chambers is provided with an inlet and an outlet, and each of the inlets and outlets is provided with a switch door 18 that is driven to rise and fall by a drive mechanism. The drive mechanism is a cylinder, and the switch door must be closed during sandblasting.

[0039] In this embodiment of the invention, the intermediate shell flow channel sandblasting device is equipped with first, second, and third sandblasting pipes. The first and second sandblasting pipes are used to sandblast the flow channel at the front of the intermediate shell, while the third sandblasting pipe is used to sandblast the flow channel at the rear of the intermediate shell. This arrangement ensures a reasonable distribution of the sandblasting pipes, guaranteeing that both the front and rear flow channels within the intermediate shell are sandblasted, thus improving the sandblasting effect and efficiency. Furthermore, since the flow channel at the front of the intermediate shell is long and winding, two sandblasting pipes are used. The first sandblasting pipe sands one end of the flow channel at the front of the intermediate shell, while the second sandblasting pipe sands the opposite end. This two-end sandblasting method ensures more complete and thorough sandblasting of the inner front flow channel, further enhancing the sandblasting effect and efficiency.

[0040] During sandblasting, the intermediate shell is first placed at the first sandblasting station.

Then, the first sandblasting pipe descends and inserts into the sandblasting hole at the top of the intermediate shell, allowing the first sandblasting pipe to spray sand into one end of the flow channel at the front of the intermediate shell. Afterward, the intermediate shell is removed from the first sandblasting station, rotated 180 degrees, and placed at the second sandblasting station. The annular protrusion on the back of the intermediate shell is embedded in the pre-positioning groove to ensure accurate placement. Then, the second sandblasting pipe descends and inserts into the sandblasting hole at the top of the intermediate shell. At the same time, the third sandblasting pipe is inserted into the inner rear flow channel through the opening at the back of the inner rear flow channel, allowing the second sandblasting pipe to spray sand into the opposite end of the flow channel at the front of the intermediate shell, and the third sandblasting pipe to spray sand into the inner rear flow channel. The third sandblasting pipe is inclined so that the sand particles bounce back to other areas of the flow channel in the inner rear flow channel.
