Technical Field

[0001] The utility model relates to the technical field of rust removal, and more specifically, to a sandblasting rust removal device for the surface of workpieces to be processed. Background Art

[0002] After metal rusts, rust removal must be carried out to keep the metal in its original properties. At present, industrial rust removal methods include manual rust removal, mechanical rust removal, and chemical rust removal. In mechanical rust removal, sandblasting rust removal technology is widely used. Sandblasting rust removal uses compressed air as the power to form a high-speed jet beam to spray abrasive materials (garnet sand, copper ore sand, quartz sand, emery, iron sand, Hainan sand) at high speed onto the surface of the workpiece to be processed, causing changes in the outer surface or shape of the workpiece surface.

Specific embodiments

[0023] The following specific embodiments illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] With reference to Figures 1-5, the present utility model provides a sandblasting and rust removal device for the surface of a workpiece, including a support plate 1 and a sandblasting gun 7 for sandblasting and rust removal of the workpiece. A handle can be provided on the sandblasting gun 7 for hand-held operation. One end of the sandblasting gun 7 is provided with a compressed inlet pipe 71, and the inlet end of the compressed inlet pipe 71 can cooperate with an air compressor device and a sandblasting material feeding device for material transportation. Universal moving wheels 2 are provided at the corners of the bottom of the support plate 1, and brake pads can be provided on the universal moving wheels 2 to lock the movement of the support plate 1. A height adjustment structure 3 is provided on the support plate 1, a support frame 4 is provided on the height adjustment structure 3, a rotating support structure 5 is rotatably connected inside the support frame 4, a fixed pipe 6 is provided on the rotating support structure 5, the fixed pipe 6 is rotatably connected to the support frame 4 through the rotating support structure 5, the sandblasting gun 7 is arranged inside the fixed pipe 6, and a sandblasting installation structure 8 for fixing the sandblasting gun 7 is provided on the fixed pipe 6.

[0025] The height adjustment structure 3 includes an inner column 31 fixedly connected to the upper surface of the support plate 1, an outer sleeve 32 sleeved on the inner column 31, and a first fastening bolt 33 threadedly penetrating and connected to the outer sleeve 32. The support frame 4 is fixedly connected to the top end of the inner column 31.

[0026] A plurality of fixing grooves for threaded connection of the first fastening bolt 33 are formed on the inner column 31.

[0027] Specifically, by adjusting the telescopic distance between the inner column 31 and the outer sleeve 32 and using the first fastening bolt 33 to fasten with the corresponding fixing groove in the horizontal direction, the height of the sandblasting gun 7 at the position of the fixed pipe 6 can be stably adjusted, thus meeting the operation requirements for the sandblasting height of the workpiece; the first fastening bolt 33 can adopt a butterfly bolt for manual rotation control by workers.

[0028] The rotating support structure 5 includes a support ring 51 arranged inside the support frame 4, a pair of first shaft rods 52 fixedly connected to the outer surface of the support ring 51, and a pair of second shaft rods 53 rotatably connected to the inner surface of the support ring 51. The support ring 51 is rotatably connected to the support frame 4 through the first shaft rods 52, the fixed pipe 6 is fixedly connected to the pair of second shaft rods 53, and the fixed pipe 6 is rotatably connected to the support ring 51 through the second shaft rods 53. In the present utility model, both the first shaft rods 52 and the second shaft rods 53 are rotatably connected through bearings. By using the support ring 51 to be rotatably connected to the support frame 4 through the first shaft rods 52 and the fixed pipe 6 to be rotatably connected to the support ring 51 through the second shaft rods 53, the position of the fixed pipe 6 can be adjusted for rotation in the horizontal and vertical directions, thus facilitating the operation of holding the sandblasting gun 7 with controllable sandblasting angles.

[0029] A fastening bolt II (9) is threadedly connected to the support frame (4). One end of the fastening bolt II (9) contacts a shaft rod I (52) rotatably connected to the support frame (4). A fastening bolt III (10) is threadedly connected to the support ring (51). The fastening bolt III (10) contacts a shaft rod II (53) rotatably connected to the support ring (51). Since the rotation points of the shaft rod I (52) and the shaft rod II (53) are rotatably connected through bearings, the fastening bolt III (10) or the fastening bolt II (9) should avoid the bearing positions of the shaft rod I (52) or the shaft rod II (53) for abutting. In the present utility model, both the fastening bolt III (10) and the fastening bolt II (9) are butterfly bolts that can be manually controlled.

[0030] Anti-slip pads (11) are fixedly connected to one end of each of the fastening bolt II (9) and the fastening bolt III (10). The anti-slip pads (11) can increase the contact friction between the corresponding shaft rod I (52) and shaft rod II (53) of the fastening bolt III (10) and the fastening bolt II (9). In this way, the rotation of the shaft rod I (52) and the shaft rod II (53) can be conveniently locked. By limiting the rotation of the rotary support structure (5), the sandblasting gun (7) in the fixed pipe (6) can have its sandblasting angle limited. In this way, for workpieces with a relatively flat surface, simply moving the universal moving wheels (2) can perform linear sandblasting on the workpiece surface, which is convenient to operate and has high efficiency.

[0031] The sandblasting installation structure (8) includes a lead screw (81) threadedly penetrating and connected to the fixed pipe (6), a pressing plate (82) rotatably connected to one end of the lead screw (81), and a rotating disc (83) fixedly connected to the other end of the lead screw (81). The pressing plate (82) is in close contact with the sandblasting gun (7) disposed in the fixed pipe (6). The end of the lead screw (81) can be rotatably connected to the pressing plate (82) through a bearing. The pressing plate (82) can be an annular plate, which can increase the contact area for clamping the sandblasting gun (7).

[0032] Specifically, after the sandblasting gun (7) is installed in the fixed pipe (6), at this time, the rotating disc (83) can be controlled to drive the lead screw (81) to be screwed into the fixed pipe (6) threadedly. In this way, the pressing plate (82) can be driven to move downward until the lead screw (81) cannot be screwed downward any further. At the same time, the pressing plate (82) tightly presses on the surface of the sandblasting gun (7). In this way, the assembly of the sandblasting gun (7) can be completed. Subsequently, the rotary support structure (5) can be used to provide rotation and support for the sandblasting gun (7) to achieve a more labor-saving sandblasting operation effect.
