Description

Technical Field

[0001] The present application relates to the technical field of rust removal equipment, and in particular to a floating rust removal device. Background Art

[0002] In order to make the rust removal head better adhere to the uneven rust removal treatment surface to achieve a better rust removal effect, the current rust removal equipment usually configures a buffer mechanism for the rust removal head, so that the rust removal head has a certain floating displacement, so that it can adapt to the uneven treatment surface and achieve the effect of adhering to the treatment surface. The commonly used buffer mechanism is a spring mechanism, and the more the spring in the spring mechanism is compressed, the greater its reaction force. Therefore, when the rust removal head is working, if it encounters a high slope treatment surface, it will adhere to the treatment surface with a larger force, and if it encounters a low slope or pit treatment surface, it will adhere to the treatment surface with a smaller force, so that the force of adhering to the treatment surface is unbalanced, and then there is a situation where the treatment surface is damaged due to excessive force or the rust is not removed thoroughly due to too small force, so that the rust removal effect is still insufficient.

[0069] The embodiment of the present application discloses a floating rust removal device.

[0070] See also Figure 1 , an embodiment of a floating rust removal device provided in the embodiments of the present application includes:

[0071] The rust removal unit includes a device body 2, an air screwdriver 1, a connecting piece 3 and a rust removal head 4.

[0072] The device body 2 is provided with a first chamber, and the air screwdriver 1 is installed on the device body 2, which is used to drive the rust removal head 4 to rotate. The first end of the connecting member 3 is restricted in the first chamber and is movably arranged relative to the output shaft of the air screwdriver 1, and the first end of the connecting member 3 also rotates synchronously with the output shaft. The first end of the connecting member 3 is restricted to move in the first chamber, which can limit the connecting member 3 and prevent the movably arranged connecting member 3 from escaping from the first chamber, and the connecting member 3 is movably arranged relative to the air screwdriver 1 and rotates synchronously with the air screwdriver 1, that is, the connecting member 3 can move with a certain displacement while being driven by the air screwdriver 1 to rotate. The second end of the connecting member 3 is located outside the first chamber and is connected to the rust removal head 4, that is, the air screwdriver 1 can drive the rust removal head 4 to rotate through the connecting member 3, and at the same time, the rust removal head 4 can move relative to the air screwdriver 1 while rotating.

[0073] The first end of the connector 3 is provided with a piston portion 31, which is in sealing and sliding cooperation with the inner circumference of the first chamber, and an extrusion air cavity 201 connected to the air batch exhaust hole 11 of the air batch 1 is formed between the top surface of the piston portion 31 and the inner circumference of the first chamber. The gas coming out of the air batch exhaust hole 11 enters the extrusion air cavity 201 to push the piston portion 31, thereby providing a downward pressure to the rust removal head 4, so that the rust removal head 4 can be close to the processing surface. Such a design also allows the extrusion air cavity 201 to form a buffer air cavity, so that the rust removal head 4 can adapt to the ups and downs of the processing surface.

[0074] A first air guide channel 32 is provided in the connector 3, and the air inlet of the first air guide channel 32 is connected to the extrusion air cavity 201, and the air outlet of the first air guide channel 32 is connected to the outside world. In this way, the force exerted by the gas in the extrusion air cavity 201 on the connector 3 can be adjusted by adjusting the size of the air outlet of the first air guide channel 32. Even if the extrusion air cavity 201 is pressurized, since the extrusion air cavity 201 is connected to the outside world through the first air guide channel 32, a stable force on the connector 3 can still be maintained. This design can make the force exerted by the gas in the extrusion air cavity 201 on the connector 3 balanced and stable, ensuring that the rust removal head 4 can stick to the treatment surface with a stable force no matter what treatment surface it encounters, avoiding damage to the treatment surface, and achieving a better rust removal effect.

[0075] The above is the first embodiment of a floating rust removal device provided in the embodiment of the present application. The following is the second embodiment of a floating rust removal device provided in the embodiment of the present application. For details, please refer to Figures 1 to 6 .

[0076] Based on the solution of the above embodiment 1:

[0077] Furthermore, in order to facilitate the installation and arrangement of the air screwdriver 1, the device body 2 is also provided with a second chamber, and the air screwdriver 1 is installed in the second chamber. At the same time, a heat dissipation air cavity 202 surrounding the air screwdriver 1 is provided between the outer circumference of the air screwdriver 1 and the inner circumference of the second chamber, and the air screwdriver exhaust hole 11 is connected with the heat dissipation air cavity 202. The device body 2 is also provided with a second air guide channel 203 for connecting the heat dissipation air cavity 202 with the extrusion air cavity 201. By providing the heat dissipation air cavity 202, and allowing the gas coming out of the air screwdriver exhaust hole 11 to first pass through the heat dissipation air cavity 202 and then be transported from the heat dissipation air cavity 202 into the extrusion air cavity 201, the gas discharged from the air screwdriver exhaust hole 11 can be further utilized, so as to cool the air screwdriver 1 and increase the service life of the air screwdriver 1.

[0078] Furthermore, in order to facilitate the conduction between the air screw exhaust hole 11 and the heat dissipation air cavity 202 , the air screw exhaust hole 11 is arranged on the outer peripheral surface of the air screw 1 at a position corresponding to the heat dissipation air cavity 202 .

[0079] Furthermore, in order to make the overall structure more compact, the output shaft of the air screwdriver 1 extends into the first chamber after installation, and the first end of the connecting member 3 is movably sleeved on the output shaft along the axial direction of the output shaft, and rotates synchronously with the output shaft to achieve direct connection between the connecting member 3 and the output shaft. Of course, the connecting member 3 can also be connected to the output shaft of the air screwdriver 1 through a transmission assembly, such as a synchronous pulley, etc., without specific limitation.

[0080] Furthermore, in terms of the structural composition of the device body 2, it includes a cylindrical shell, wherein the first chamber and the second chamber can be arranged in the cylindrical shell from bottom to top.

[0082] Furthermore, the cylinder shell specifically includes a first cylinder body 21 and a second cylinder body 22. The first cylinder body 21 is provided with a through cavity, and a partition 210 is provided in the through cavity. The partition 210 divides the through cavity into an upper chamber and a lower chamber, and the upper chamber forms the second chamber. The partition 210 is provided with a first avoidance hole 213 for avoiding the output shaft, so as to facilitate the installation of the air screwdriver 1.

[0083] The second cylinder 22 is detachably mounted in the lower chamber, which is convenient for disassembly and maintenance. A concave cavity is provided on the top of the second cylinder 22, and a second avoidance hole 220 for avoiding the connecting member 3 is provided at the bottom of the concave cavity, and the concave cavity forms the first chamber. The device body 2 constructed by the above design can make the overall structure more compact and convenient for disassembly and maintenance. The diameter of the second avoidance hole 220 should be smaller than the diameter of the concave cavity, that is, to ensure that the piston part 31 will not fall out of the second avoidance hole 220, so as to achieve the purpose of limiting the connecting member 3 in the first chamber.

[0084] Furthermore, with regard to the formation of the second air guide channel 203, an air guide groove 212 is provided on the inner circumferential surface of the through cavity, one end of the air guide groove 212 is connected to the heat dissipation air cavity 202, and the other end passes through the partition 210 and is connected to the extrusion air cavity 201, and a second air guide channel 203 is formed between the air guide groove 212 and the outer circumferential surface of the air screw 1.

[0085] Furthermore, there may be multiple second air guiding channels 203 distributed in a circumferential manner, so that the gas can enter the extrusion air cavity 201 more evenly and quickly.

[0086] Furthermore, with regard to the detachable cooperation between the second cylinder 22 and the first cylinder 21, a first internal thread is provided on the inner circumferential surface of the lower chamber, and a first external thread that cooperates with the first internal thread is provided on the outer circumferential surface of the cylinder section of the second cylinder 22 extending into the lower chamber, thereby achieving detachable connection through thread cooperation.

[0087] Furthermore, with regard to the structure of the connecting member 3, it is designed as a shaft rod structure. The interior of the connecting member 3 is provided with a shaft hole 30 for the output shaft to be movably inserted and rotatably matched with the output shaft. The cross-sectional shape of the shaft hole 30 is adapted to the cross-sectional shape of the output shaft, ensuring that the output shaft can slide with the shaft hole 30 in the axial direction and can rotate synchronously in the rotational direction.

[0088] Further, as for the formation of the piston portion 31, an annular flange is provided at the first end of the connector 3 to form the piston portion 31. As for the connection between the second end of the connector 3 and the rust removal head 4, the second end of the connector 3 is provided with a connector 33, the connector 33 is provided with a second external thread, the rust removal head 4 is provided with a connecting hole 40, the connecting hole 40 is provided with a second internal thread matching the second external thread, and the detachable connection with the rust removal head 4 is also achieved through a threaded connection, which is convenient for disassembly and maintenance.

[0089] Furthermore, in order to make the connection and fixation of the rust removal head 4 more firmly and reliably, the rust removal head 4 is also provided with a locking hole 41 connected to the connecting hole 40, and a tightening screw 42 is provided on the locking hole 41, and further fixation is achieved by tightening the tightening screw 42.

[0090] Furthermore, a chamber exhaust hole 221 communicating with the outside is provided at the lower end of the inner peripheral surface of the first chamber, and the minimum height of the chamber exhaust hole 221 from the inner bottom surface of the first chamber is greater than or equal to the thickness of the piston part 31. With such a design, when the air pressure in the extrusion air cavity 201 is too high, causing the piston part 31 to contact the inner wall surface of the first chamber, the chamber exhaust hole 221 is connected to the extrusion air cavity 201, which can assist in exhausting, further improving the stability and reliability of use.

[0091] Furthermore, the chamber exhaust holes 221 may be multiple and distributed in a circular pattern, without any specific limitation.

[0092] Furthermore, in the present application, there may be multiple first air guide channels 32 distributed in a circumferential manner, without any specific limitation.

[0093] Furthermore, when there are multiple rust removal units, an integrated air intake module 5 can be additionally provided, and multiple rust removal units are mounted on the integrated air intake module 5, and the air blowers 1 of each rust removal unit are respectively connected to the air intake channel 51 on the integrated air intake module 5. In this way, the number of air pipes can be reduced, and the overall structure is simpler.

[0094] Furthermore, the rust removal head 4 is specifically a steel brush head, and may also be other rotating type rust removal structural parts, without specific limitation.

[0095] The above is a detailed introduction to a floating rust removal device provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope.
