Description

Technical Field

[0001] This utility model relates to the field of steel casting cleaning technology, specifically a sandblasting cleaning device for the inner cavity of steel castings. Background Technology

[0002] If cast steel parts are not used for a long time, their surface is very prone to oxidation and rust. If not treated in time, the service life of the cast steel parts will be reduced.

[0003] Sandblasting is an extremely efficient cleaning method. Existing equipment removes dirt from the surface of cast steel parts by spraying sand at high speed. However, it is very inconvenient to clean the inner cavities of some cast steel parts. Existing equipment is not easy to put into the inner cavity, is not easy to move, and cannot quickly remove dirt from the inner cavity.

[0004] To address the aforementioned problem of inconvenient cleaning of the inner cavity of cast steel parts, a device that can be easily inserted into the inner cavity of the cast steel parts is designed to enable internal cleaning, thus avoiding the aforementioned problem. Utility Model Content

[0005] To overcome the problem of inconvenient cleaning of the inner cavity of existing cast steel parts.

[0006] The technical solution of this utility model is as follows: a sandblasting cleaning device for the inner cavity of a cast steel part, including a frame, a rack and a slider; it also includes a sandblasting gun and a connector. The rack is fixedly connected to the upper end of the frame, and the slider is slidably connected to the frame. The slider has a rectangular hole for the rack to pass through. The sandblasting gun is fixedly installed at the upper end of the slider. A through hole is provided at the center of the slider. The end of the sandblasting gun is set in the hole of the slider. The connector is fixedly installed at the upper end of the sandblasting gun. The frame is provided with a moving mechanism that fits against the inner cavity surface of the cast steel part, and one end of the frame is provided with a positioning mechanism fixed to the upper end of the cast steel part.

[0007] Preferably, the sandblasting connecting pipe is first connected to the joint. As the slider slides on the frame, the sandblasting gun on the slider cleans the inner cavity of the cast steel part through the hole of the slider. The moving mechanism drives the sandblasting gun to clean the dirt on the inner cavity of the cast steel part by moving at a constant speed, thereby achieving rapid cleaning. The positioning mechanism uses the support structure to hang the frame on the cast steel part, thereby facilitating the subsequent movement of the frame position.

[0008] Preferably, the moving mechanism includes a housing, a motor, a connecting shaft, a gear, a support frame, and a roller. The upper end of the slider is fixedly connected to the housing, and the motor is fixedly installed on one side of the housing. The output shaft of the motor passes through one side of the housing, and one end of the motor's output shaft is fixedly connected to the connecting shaft. One end of the connecting shaft is fixedly connected to the gear. The support frame is fixedly connected to one side of the frame, and the roller is rotatably connected to the support frame. When the motor on the housing is started, the motor drives the connecting shaft to rotate the gear. Under the action of the rack, the gear drives the slider to move upward. The sandblasting gun on the slider cleans the inner cavity of the cast steel part through the holes of the slider.

[0009] Preferably, the slider is provided with a rectangular through-hole for the gear to rotate. The gear meshes with the rack, and the rectangular through-hole on the frame provides space for the gear to rotate, facilitating the movement of the slider.

[0010] Preferably, the support frames are symmetrically arranged at both ends of the frame, and the height of the support frames is higher than the height of the lower end of the slider. The symmetrical arrangement of the support frames ensures the stability of the frame during the movement of the slider, and the height of the support frames is higher than the height of the lower end of the slider to provide space for the slider to move.

[0011] Preferably, the positioning mechanism includes a connecting rod, a connecting seat, a positioning bolt, a frosted ring, a rotating frame, a roller, and a positioning bracket. A connecting rod is fixedly connected to one side of the frame, and a connecting seat is fixedly connected to one end of the connecting rod. A positioning bolt is threadedly connected to the upper end of the connecting seat, and a frosted ring is fixedly connected to the lower end of the positioning bolt. A rotating frame is rotatably connected to the connecting seat, and a roller is rotatably connected to the rotating frame. A positioning bracket is slidably connected to the rotating frame, and a positioning bolt is threadedly connected to the positioning bracket. The position of the positioning bracket is determined according to the wall thickness of the cast steel part. The positioning bracket is slid to the surface of the cast steel part, and then the positioning bolts on both sides of the positioning bracket are tightened to fix the position of the positioning bracket. Then, the positioning bolts on the connecting seat are tightened one by one. The rotating frame, connecting rod, positioning bracket, and support frame form a support structure to hang the frame on the cast steel part. After cleaning one area, the rotating frame is slid, and the position of the frame moves, thereby cleaning different areas inside the cast steel part.

[0012] Preferably, the connecting seat has a cavity, the rotating shaft of the rotating frame passes through the cavity of the connecting seat, the lower end of the positioning bolt passes through the upper end of the connecting seat, the inner surface of the frosted ring is in contact with the surface of the rotating shaft of the rotating frame, and after the positioning bolt is tightened, the frosted ring and the rotating shaft of the rotating frame are rubbed together in the cavity, thereby fixing the position of the rotating frame.

[0013] Preferably, the two positioning bolts are symmetrically arranged on both sides of the positioning frame, and one end of the two positioning bolts passes through the surface of the positioning frame. Tightening the two positioning bolts fixes the position of both sides of the positioning frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model can insert the sandblasting gun into the inner cavity of the cast steel part and clean the inner cavity surface evenly. Compared with existing equipment, the sandblasting gun can be easily inserted and removed, improving work efficiency.

[0016] 2. The positioning mechanism adopted by this utility model can quickly hang the frame on the cast steel part, and clean different positions by changing the position of the frame. Furthermore, the rotating frame can be used to clean the inner wall of the cavity at different tilt angles, thereby increasing the range of applications. Attached Figure Description
