[0002] During the existing wheel hub processing process, it is necessary to cut the spokes and other parts. The wheel hub is generally installed in a machining center for processing. After the processing is completed, a large amount of cutting material will remain on it. If these cutting materials are not removed, it will affect the subsequent machining operations.

[0003] Therefore, the existing method is that after the robot is taken out, it needs to be manually blown off with an air gun, but the manual operation is labor-intensive and inefficient, and cannot meet the needs of automated continuous processing. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic unit blowing tool, which can be installed on one side of a manipulator. The manipulator moves the processed wheel hub to the top of the manipulator for automatic blowing. Subsequently, the manipulator only needs to place the wheel hub on a subsequent conveying mechanism. The utility model has a high degree of automation and is suitable for automated continuous processing. At the same time, it reduces the amount of manual labor and does not require manual blowing.

[0005] The solution of the utility model to solve the technical problem is:

[0006] An automatic unit air blowing tool comprises a fixed mounting plate, a ventilation connection seat is fixed to the middle of the top surface of the fixed mounting plate, a bottom center through hole is formed in the middle of the bottom surface of the ventilation connection seat, an upper mounting groove extending downward is formed in the middle of the top surface of the ventilation connection seat, the top end of the bottom center through hole is communicated with the upper mounting groove, a rotating shaft is movably connected to the upper mounting groove via a bearing, the upper part of the rotating shaft extends out of the top surface of the ventilation connection seat, an upward extending air guide hole is formed in the middle of the bottom surface of the rotating shaft, and the air guide hole is communicated with the bottom center through hole;

[0007] The upper portions of the left and right side walls of the rotating shaft are each formed with a screw-through hole, which is connected to the air guide hole. One end of the two transverse tubes is fixed in the corresponding screw-through hole and is connected to the air guide hole.

[0008] A plurality of air blowing pipes are connected to or formed on the top side wall of the transverse tube.

[0011] A lower screw connection hole is formed in the middle of the bottom surface of the fixed installation plate. The lower screw connection hole is located directly below the bottom center through hole and communicates with the bottom center through hole.

[0012] A lower connector is screwed to the bottom of the lower screw-connected through hole, and an air inlet pipe is screwed to the outer end of the lower connector.

[0013] The outstanding effects of the utility model are:

[0014] Compared with the existing technology, it can be installed on one side of the robot arm. The robot arm moves the processed wheel hub to the top of it for automatic blowing.

[0022] The lower screw through hole 11 is located directly below the bottom center through hole 21 and communicates with the bottom center through hole 21. A downwardly extending upper mounting groove 22 is formed in the middle of the top surface of the ventilation connection seat 20. The top of the bottom center through hole 21 communicates with the upper mounting groove 22. A rotating shaft 30 is movably connected to the upper mounting groove 22 through a bearing. The upper part of the rotating shaft 30 extends out of the top surface of the ventilation connection seat 20. An upwardly extending air guide hole 31 is formed in the middle of the bottom surface of the rotating shaft 30. The air guide hole 31 communicates with the bottom center through hole 21.

[0023] The upper portions of the left and right side walls of the rotating shaft 30 are each formed with a screw-through hole, which communicates with the air guide hole 31. One end of the two transverse tubes 40 is fixed in the corresponding screw-through hole and communicates with the air guide hole 31.

[0024] The outer end of the transverse tube 40 is bent upward and outward obliquely to form a first air outlet pipe portion 42 , and a plurality of air blowing pipes 41 are connected to or formed on the top side wall of the transverse tube 40 .

[0025] Furthermore, the air blowing pipe 41 is a pipe body extending obliquely upward and outward, the air blowing pipe 41 and the first air outlet pipe portion 42 on the left are inclined backward, and the air blowing pipe 41 and the first air outlet pipe portion 42 on the right are inclined forward.

[0026] Each transverse tube 40 is provided with two air blowing tubes 41 , the bottom ends of the two air blowing tubes 41 are welded and fixed on the top plate of the corresponding transverse tube 40 and communicate with corresponding through holes formed on the top plate of the corresponding transverse tube 40 .

[0027] The upper ends of all the air blowing pipes 41 and the first air outlet pipe portion 42 are screwed with the upper connector 2 .

[0028] The upper connector 2 can be connected to a flat blowing head 9 as needed, such as Figure 3 As shown, there may also be a blowing head 9 with a central through hole smaller than the inner diameter of the blowing pipe 41, such as Figure 4 As shown, different blowing heads 9 can be selected according to the blowing needs.

[0029] Furthermore, the outer ring of the bearing is clamped on the inner wall of the upper mounting groove 22, and the inner ring of the bearing is clamped on the outer wall of the rotating shaft 30. A lower radial extension edge is formed on the bottom outer wall of the rotating shaft 30, and the lower radial extension edge is pressed against the bottom surface of the inner ring of the bearing. The top surface of the ventilating connection seat 20 is fixedly connected to the top fixing cover 80 by bolts, and the rotating shaft 30 is inserted into the middle through hole of the top fixing cover 80, and its upper part extends out of the top surface of the top fixing cover 80; a retaining spring is clamped in the annular groove formed on the middle outer wall of the rotating shaft 30, and the outer top surface of the retaining spring is close to the bottom surface around the middle through hole of the top fixing cover 80, and the outer bottom surface of the retaining spring is close to the top surface of the inner ring of the bearing.

[0030] Furthermore, an external thread is formed on the outer side wall of the inner end of the transverse tube 40, one end of the connector 1 is screwed onto the external thread, and the other end of the connector 1 is screwed into the screw-through hole, and the transverse tube 40 is connected to the air guide hole 31 through the connector 1.

[0031] In this embodiment, sealing members such as sealing rings can be provided between various connecting components for sealing (partially omitted in the accompanying drawings). Of course, a sealing device may not be provided. Without a sealing device, gas may leak from the gaps between the components, but the leakage is not large and does not affect the overall air volume blown to the hub 100. It can still ensure that the debris on the hub 100 is blown off.

[0032] When this embodiment is in use, the hub 100, on which the spokes and other top structures have been processed, is moved by a robot to the top of this embodiment, close to all the blowing pipes 41 and the first air outlet pipe portion 42, but not touching them. Then, the corresponding solenoid valve is opened, allowing air to enter the air inlet pipe 13, which enters the bottom central through hole 21 through the lower screw hole 11, and then enters the rotating shaft 30. It is then blown out from all the blowing pipes 41 and the first air outlet pipe portion 42, blowing air onto the hub 100 above it, so that all the chips on it are blown off.

[0033] Among them, since the blowing pipe 41 and the first air outlet pipe part 42 on the left are tilted backward (about 5°), and the blowing pipe 41 and the first air outlet pipe part 42 on the right are tilted forward (about 5°), at this time, the rotating shaft 30 rotates, so that the wheel hub 100 can be rotated and blown, so that the blowing area is large, the blowing is uniform, the blowing effect is improved, and the debris on the spokes and the inner wall of the rim of the wheel hub 100 is blown off, which facilitates the subsequent normal processing of the inner wall of the rim and the bottom surface of the spokes, and ensures the processing effect.

[0034] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
