[0002] Currently, when processing products, the processing heads, such as welding heads, fixtures, and spray guns, need to be positioned. The commonly used positioning adjustment mechanism is the XYZ movement mechanism. The XYZ movement mechanism can only perform translation and cannot adjust the processing orientation of the processing head. If multiple surfaces of a product need to be processed, and these surfaces are not parallel, it will result in the inability to process all surfaces. Therefore, it is necessary to design an additional positioning adjustment mechanism to achieve the adjustment of the processing direction. Summary of the Invention

Detailed Implementation
[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0028] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0029] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0031] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 5 As shown.
[0032] Example 1: See Figure 1 , Figure 2 as well as Figure 3 A position adjustment mechanism, comprising:
[0033] The first rotating device 1 is provided with a first rotating shaft, the first rotating shaft is connected to a first connecting plate 3 and drives the first connecting plate 3 to rotate;
[0034] The second rotating device 5 is provided with a second rotating shaft, which is connected to a second connecting plate 7 and drives the second connecting plate 7 to rotate; and the second rotating device 5 is fixed to the first connecting plate 3.
[0035] The length direction of the first rotating shaft is perpendicular to or at an angle to the length direction of the second rotating shaft.
[0036] In implementation, the second connecting plate 7 can be connected to the workpiece or processing head to drive the workpiece or processing head to rotate in two dimensions. For example, if the length directions of the first and second rotating axes are vertical, horizontal, or longitudinal respectively, the workpiece or processing head can be rotated and adjusted in any two of these directions. If combined with an XYZ movement mechanism, it will achieve five-dimensional adjustment, providing a wide range of adjustments.
[0037] It is understandable that the length direction of the first rotating shaft can also be clamped to the length direction of the second rotating shaft, such as when the two surfaces to be machined are set at an angle.
[0038] Preferably, the first rotating device 1 includes a first rotating motor 12 and a first reducer 11 fixedly connected, the first rotating motor 12 drives the first reducer 11, and the first reducer 11 includes the first rotating shaft.
[0039] The second rotating device 5 includes a second rotating motor 52 and a second reducer 51 fixedly connected. The second rotating motor 52 drives the second reducer 51, and the second reducer 51 includes the second rotating shaft.
[0040] This technical solution configures at least one of the first rotating device 1 and the second rotating device 5 as a combination of a rotary motor and a reducer, so that at least one of the corresponding first rotating device 1 and second rotating device 5 operates at a relatively slow output, making it easy to control. For example, the first rotating device 1 uses a first rotary motor 12 and a first reducer 11. The first rotary motor 12 drives the first reducer 11 to operate. The first rotary motor 12 can be a servo motor. It is understood that the second rotary motor 52 can also be a servo motor for easy control. The first shaft of the first reducer 11 drives the first connecting plate 3 to rotate, and simultaneously drives the second rotating device to rotate.
[0041] Furthermore, the first rotating shaft is connected to a first rotating disk 2, and the first rotating disk 2 is fixedly connected to the first connecting plate 3.
[0042] To facilitate the fixed connection between the first rotating shaft and the first connecting plate 3, this embodiment uses a first rotating disk 2 between the first rotating shaft and the first connecting plate 3. The first rotating shaft drives the first rotating disk 2 to rotate, and the first rotating disk 2 in turn drives the first connecting plate 3 to rotate. The connection area between the first rotating disk 2 and the first connecting plate 3 is relatively large, resulting in a stable connection. Various connection methods can be used to fix the first rotating disk 2 and the first connecting plate 3, such as welding or snap-fitting. In this embodiment, a bolt connection is used. Multiple connection holes are provided on both the first rotating disk 2 and the first connecting plate 3, and then the connection is made by bolts, facilitating assembly and disassembly.
[0043] Furthermore, the first connecting plate 3 includes a first horizontal section 31 and a first vertical section 32 fixedly connected. The first horizontal section 31 is fixedly connected to the first rotating disk 2, and the second reducer 51 is fixedly connected to the first vertical section 32. Secondly, to facilitate wiring, a through hole can be provided in the middle of the first horizontal section 31.
[0044] To facilitate connection, in this embodiment, the first connecting plate 3 is arranged in an inverted L-shape, so that the first rotating shaft and the second reducer 51 can be connected to the two sides of the first connecting plate 3 respectively without interference; at the same time, it is also convenient for installation and makes reasonable use of space. The second reducer 51 can be arranged horizontally or vertically.
[0045] Secondly, the first horizontal section 31 and the first vertical section 32 can be integrally formed, such as by bending a steel plate or by direct casting. Alternatively, they can be connected by two connecting blocks. To further facilitate efficient use of space, the second reducer 51 can be L-shaped; alternatively, it can be a horizontal straight line.
[0046] Preferably, a reinforcing piece 4 is connected between the first horizontal segment 31 and the first vertical segment 32.
[0047] Since the second reducer is connected to the vertical section, the vertical section needs to bear the weight of the second reducer and others. In order to prevent the first vertical section 32 from deforming, this embodiment has a reinforcing plate 4 connected between the first horizontal section 31 and the first vertical section 32. The reinforcing plate 4 is specifically connected to the side of the first vertical section 32 and the first horizontal end.
[0048] Furthermore, the second rotating shaft is connected to a second rotating disk 6, and the second rotating disk 6 is fixedly connected to the second connecting plate 7.
[0049] Further, the second connecting plate 7 includes a second vertical section 71 and a second horizontal section 72 fixedly connected. The second vertical section 71 is fixedly connected to the second rotating disk 6, and the second horizontal section 72 is fixedly connected to the third reducer 81. Preferably, the second vertical section 71 is provided with a groove that mates with one end of the second horizontal section 72. A wire hole 73 is also provided in the middle of the second vertical section 71 to facilitate wiring. See [reference needed]. Figure 4 A reinforcing plate 4 connects the second horizontal section 71 and the second vertical section 72.
[0050] For ease of connection, the second rotating shaft is connected to the second connecting plate 7 via the second rotating disk 6. The connection area between the second rotating disk 6 and the second connecting plate 7 is relatively large, resulting in a stable connection. Secondly, to facilitate the fixing of the second horizontal section 72, the second vertical section 71 is provided with a matching groove, into which one end of the second horizontal section 72 is inserted. Preferably, the second horizontal section 72 is connected to the second vertical section 71 by bolts.
[0051] Example 2: A spray gun device, including the above-mentioned position adjustment mechanism, further including a spray gun and a third rotary motor 8, see [link to documentation]. Figure 5 The main shaft of the third rotary motor 8 is connected to a cam 81, which abuts against the flow control valve 84 of the spray gun. The flow control valve 84 is inserted into the flow channel 83 of the spray gun. The cam 81 is used to control the insertion depth of the flow control valve 84. The flow control valve 84 is connected to an elastic element 82, which is used to push the flow control valve 84 outward, like a flow channel switch. The spray gun is connected to the main shaft.
[0052] Furthermore, the spray gun includes a spray end 20 and an operating end 10. The spray end 20 is connected to the main rotating shaft, and the operating end 10 is fixed to the second horizontal section 72.
[0053] In specific settings, the spray end 20 is used to spray paint, coatings, etc.; the spray end 20 is connected to the main rotating shaft, and the main rotating shaft drives the spray end 20 to rotate, which can make the sprayed material more uniform; the control end is used to control the working state of the spray end 20, and the control end can be an operating handle, etc., and can be controlled by a control system.
[0054] Preferably, the second horizontal section 72 is also connected to a sensing module, which detects whether the spray gun has been installed on the operating handle, thereby controlling the automatic spraying operation.
[0055] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
