Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to an adjustable spray gun assembly for a sandblasting machine. Background Art

[0002] A sandblasting machine is a machine that can use abrasives (such as sand, steel shot, etc.) to spray the metal surface. It can remove surface dirt, oxides, rust, etc., and improve the surface roughness and adhesion. Sandblasting machines are usually used in the fields of metal processing, automobile manufacturing, ship maintenance, construction, etc.

[0003] When common sandblasting machines are used for component processing, the components need to be placed at the nozzle of the sandblasting machine. When the components are relatively large, the operator needs to continuously move the components to enable the nozzle of the sandblasting machine to fully process the surface of the components, but this will increase the labor force. In order to improve it, an adjustable spray gun assembly for a sandblasting machine is proposed here. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an adjustable spray gun assembly for a sandblasting machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An adjustable spray gun assembly for a sandblasting machine includes a mounting frame and a spray gun. A screw rod is arranged on the mounting frame through a moving motor. A nut is threadedly sleeved on the screw rod. An adapter frame is arranged on the nut through an insertion mechanism. An extrusion groove is arranged on the outer wall of the adapter frame. A limiting block is arranged in the extrusion groove through an extrusion mechanism. A limiting port is arranged on the mounting frame. A support frame is fixedly arranged on the adapter frame. An installation ring is fixedly arranged on the support frame. A transmission gear fixedly connected with the spray gun is rotatably arranged on the support frame. A rotation motor is arranged on the support frame. The rotation motor is connected with the transmission gear through a rotation mechanism.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-6 , an adjustable spray gun assembly of a sandblasting machine, including a mounting bracket 1 and a spray gun 7. The mounting bracket 1 is installed on the outer wall of the machine body that cooperates with the spray gun 7. Both the spray gun 7 and the machine body are products of the prior art, and their specific structures and working principles will not be elaborated here. For details, reference can be made to the prior art disclosures.

[0025] A screw rod 2 is provided on the mounting bracket 1 through a moving motor 3. A nut 13 is threadedly sleeved on the screw rod 2. A connecting frame 15 is provided on the nut 13 through an insertion mechanism. An extrusion groove 16 is provided on the outer wall of the connecting frame 15. A limiting block 5 is provided in the extrusion groove 16 through an extrusion mechanism. A limiting opening 4 is provided on the mounting bracket 1. A support frame 10 is fixedly provided on the connecting frame 15. A mounting ring 11 is fixedly provided on the support frame 10. A transmission gear 6 fixedly connected to the spray gun 7 is rotatably provided on the support frame 10. A rotating motor 8 is provided on the support frame 10. The rotating motor 8 is connected to the transmission gear 6 through a rotating mechanism. A sliding sleeve 12 connected to the spray gun 7 is slidably sleeved on the mounting ring 11 through a reset mechanism.

[0026] The insertion mechanism includes an insertion block 19 provided on the cover of the connecting frame 15. A slot corresponding to the insertion block 19 is provided on the outer wall of the nut 13. After the insertion block 19 enters the slot, the connecting frame 15 can be driven to move synchronously with the nut 13 without vertically moving up and disengaging from the nut 13.

[0027] The extrusion mechanism includes an extrusion spring 20 provided in the extrusion groove 16. The two ends of the extrusion spring 20 are elastically connected to the outer wall of the limiting block 5 and the inner wall of the extrusion groove 16 respectively. The extrusion spring 20 can realize the extrusion and pushing operation of the limiting block 5, and can extrude the limiting block 5 into the limiting opening 4 to realize the vertical limit of the connecting frame 15, thereby preventing it from disengaging from the nut 13.

[0028] The rotating mechanism includes a driving gear 9 provided on the output shaft of the rotating motor 8. The driving gear 9 is an incomplete gear and meshes with the transmission gear 6. When the driving gear 9 rotates, it can drive the transmission gear 6 to rotate, thereby driving the spray gun 7 to rotate. Since it is an incomplete gear, when the part of the driving gear 9 without teeth corresponds to the transmission gear 6, it can no longer drive the transmission gear 6 to rotate.

[0029] The reset mechanism includes a retaining ring 17 fixedly provided on the mounting ring 11. A reset spring 18 is sleeved outside the mounting ring 11. Both ends of the reset spring 18 are elastically connected to the outer wall of the retaining ring 17 and the outer wall of the sliding sleeve 12 respectively. When the part of the driving gear 9 without teeth corresponds to the transmission gear 6, under the elastic potential energy provided by the above-mentioned reset spring 18, the spray gun 7 can be driven by the sliding sleeve 12 to rotate and reset.

[0030] A limiting rod 14 is provided on the mounting bracket 1. The limiting rod 14 is parallel to the screw rod 2. The limiting rod 14 slidably penetrates through the nut 13, and the limiting rod 14 realizes the limitation of the nut 13, effectively preventing it from rotating together with the screw rod 2.

[0031] The initial state of the present utility model is as Figure 6 shown. When the present utility model is in use, starting the rotating motor 8 can drive the driving gear 9 to rotate. The driving gear 9 can drive the spray gun 7 to rotate by means of the transmission gear 6, and the sliding sleeve 12 slides on the mounting ring 11 and moves away from the retaining ring 17 at the same time, and the reset spring 18 is in a stretched state. After the spray gun 7 rotates a certain amplitude, at this time, the part of the driving gear 9 without teeth corresponds to the transmission gear 6. At this time, the transmission gear 6 loses the restraint of the meshing force. At this time, under the restoring trend of the reset spring 18, the spray gun 7 is driven to rotate and reset. Repeating this process can realize the swinging of the spray gun 7.

[0032] In this solution, after starting the moving motor 3, the screw rod 2 can be driven to rotate. When the screw rod 2 rotates, in cooperation with the nut 13, the connecting frame 15 and the support frame 10, the movement adjustment of the spray gun 7 relative to the mounting bracket 1 can be realized, so as to be closer to or farther away from the workpiece to be processed.

[0033] In this solution, after pressing the limiting block 5 in the limiting port 4, the limiting block 5 compresses the compression spring 20 and disengages from the limiting port 4. Immediately, the vertical limitation of the connecting frame 15 is released. Directly lifting the connecting frame 15 can complete the disassembly of the spray gun 7 and other components from the mounting bracket 1 and other components, facilitating the overhaul, maintenance or replacement of the spray gun 7 and other components.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
