[0002] As a special auxiliary equipment, the double-axis positioner is suitable for welding position displacement of rotary work to obtain the ideal processing position and welding speed. When working, the two axes move together. On the one hand, there will be axial rotation, and on the other hand, there will be radial rotation. The movement in the two directions is combined together. The flipping and rotation make the workpiece fixed on the workbench reach the required welding assembly angle, which can obtain a satisfactory welding speed.

[0003] In the use of the prior art double-axis positioner, for example, the Chinese utility model patent with the authorization publication number CN 215616154 U discloses "a double-axis U-shaped servo positioner", which enables the workpiece on the workbench to reach the required welding assembly angle through flipping and rotating actions.

[0004] In the above-mentioned prior art, the load-bearing tonnage of the dual-axis positioner platform is generally about two tons, and in actual application, a fixed structure is set on the platform to fix the parts to be processed. When the platform is overloaded or the fixed structure has been used for a long time and its limit is loose, the parts to be processed will first fall from the translation and then perform movements such as sliding or rolling, which can easily harm workers or surrounding equipment. Therefore, a dual-axis platform hollow servo positioner is proposed to solve the above problems. Summary of the invention

[0009] A protective component, which is movably arranged on the base;

[0010] The transmission structure includes a speed change assembly, a transmission shaft, a gear one and a rack, wherein the rack is arranged on the protective component, the speed change assembly is driven by the servo motor, and then transmitted through the transmission shaft, gear one and the rack, thereby driving the protective component to change position in real time for protection.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the protective component includes a displacement slider and a displacement plate. A displacement chamber is opened on the base, and the cross-section of the displacement chamber is an inverted T-shape.

[0019] Furthermore, the pneumatic component includes a pneumatic box, an air plug and a connecting rod, wherein the air plug is movably arranged in the pneumatic box.

[0020] Furthermore, the lubrication component includes a lubrication box and an oil outlet pipe, wherein one end of the oil outlet pipe is located at the oil inlet, and the other end thereof is set in the lubricating oil in the lubrication box.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] like Figure 1 and Figure 2 As shown, a dual-axis platform hollow servo positioner in this embodiment includes a base 1, a processing platform 2, a rotating mechanism 3, a flipping structure 4, a protective component 5 and a transmission structure 6, wherein the base 1 consists of a seat plate and a bracket assembly, the bracket is fixed on the seat plate, the base 1 is arranged below the rotating mechanism 3, the flipping structure 4 is supported on the base 1 by the bracket, the flipping structure 4 is used to drive the rotating mechanism 3 and the processing platform 2 to flip, the rotating mechanism 3 is arranged below the processing platform 2, and is used to drive the processing platform 2 to rotate, the processing platform 2 is used to fix the parts to be processed, thereby completing the flipping and rotation of the parts to be processed, in addition, the protective component 5 can be movably arranged on the base 1, and the protective component 5 is transmitted through the transmission structure 6, and the power source of the flipping structure 4 is used to allow the protective component 5 to be displaced in real time to achieve fall protection.

[0033] It should be noted that the base 1 is fixed to the floor of the workshop by bolts, so that the dual-axis platform type hollow servo positioner has good stability.

[0034] That is, when in use, when the flipping structure 4 drives the rotating mechanism 3 and the processing platform 2 to flip, the power source of the flipping structure 4 will drive the protective component 5 to change position in real time through the transmission structure 6, so that the protective component 5 can perform fall protection, making the dual-axis platform hollow servo positioner safer and more reliable.

[0035] In this embodiment, if Figure 3As shown, the flipping structure 4 includes a servo motor 41, a reduction assembly 42 and a rotating arm 43. A cross frame is provided on one side of the bracket to support the servo motor 41. There is a distance between the servo motor 41 and the bracket so that the transmission structure 6 has sufficient assembly space. The reduction assembly 42 is partially arranged in the bracket, and the rotating arm 43 is arranged at the output end of the reduction assembly 42, so that the servo motor 41 in the flipping structure 4 can be used to drive the rotating mechanism 3 and the processing platform 2 to flip.

[0036] like Figure 5 As shown, the reduction assembly 42 includes an outer cover 421, a gear four 422 and a gear five 423, wherein an oil inlet 424 is provided at the top of the outer cover 421, an oil outlet 425 is provided at the bottom of the outer cover 421, and the gear four 422 is meshed with the gear five 423. When the gear four 422 is driven by the servo motor 41, the gear five 423 can drive the rotating arm 43, the rotating mechanism 3 and the processing platform 2 to flip.

[0037] It should be noted that the reduction assembly 42 may also include a planetary reducer for reducing the drive of the servo motor 41, and the planetary reducer is arranged between the reduction assembly 42 and the servo motor 41, for example, located in a bracket. The planetary reducer is not shown in the figure. This is the prior art and will not be elaborated here.

[0038] However, if Figure 2 and 3 As shown, the transmission structure 6 includes a speed change assembly, a transmission shaft 61, a gear 62 and a rack 63, wherein the transmission shaft 61 is arranged horizontally and located above the base 1, and the rack 63 is arranged on the protective component 5. The speed change assembly is driven by the servo motor 41, and after the speed change, it is transmitted through the transmission shaft 61, the gear 62 and the rack 63, thereby driving the protective component 5 to change position in real time for protection.

[0039] In use, when the servo motor 41 is working, the servo motor 41 will first be shifted through the speed change assembly, and then transmitted through the transmission shaft 61, gear 1 62 and rack 63, thereby driving the protective component 5 to shift position in real time for protection.

[0040] In one embodiment, if Figure 2 and Figure 4 As shown, the protective component 5 includes a displacement slider 51 and a displacement plate 52. A displacement chamber 11 is opened on the base 1, which allows the displacement slider 51 to slide back and forth, and the sliding distance must not exceed the displacement chamber 11. In addition, the cross-section of the displacement chamber 11 is an inverted T-shape, which can prevent the displacement slider 51 from escaping from the displacement chamber 11.

[0041] Moreover, the displacement slider 51 is slidably connected in the displacement chamber 11, and the displacement slider 51 is fixedly connected to the displacement plate 52, so that the protective component 5 can be supported by the base 1. A boss 53 is fixed on the displacement plate 52, and a retaining frame 54 is provided on the boss 53 to prevent the part to be processed from falling.

[0042] During use, the baffle 54 in the protective component 5 protects the forward or rearward side, while the displacement plate 52 protects the downward side. When the baffle 54 and the displacement plate 52 intercept the falling parts to be processed, they prevent the parts to be processed from continuing to roll or slide, thereby ensuring the safety of workshop workers and accessory equipment.

[0043] Further, such as Figure 3 As shown, the speed change assembly includes a pulley component 64 and a gear component 65 . The pulley component 64 is used for primary speed change, and the gear component 65 is used for secondary speed change.

[0044] To further explain, after the servo motor 41 is operating, the pulley component 64 performs a first-stage speed change, and the gear component 65 performs a second-stage speed change. The gear component 65 then drives the transmission shaft 61, gear 1 62 and rack 63 to work, so that the protective component 5 can be displaced in real time for protection.

[0045] Specifically, Figure 3 As shown, in this embodiment, the pulley component 64 includes a small wheel 641, a large wheel 642, a synchronous belt 643 and a primary shaft 644, wherein the small wheel 641 is assembled at the output end of the servo motor 41 and is driven by the servo motor 41, the synchronous belt 643 connects the small wheel 641 and the large wheel 642, and the primary shaft 644 is fixed on the inner side of the large wheel 642, so that the synchronous belt 643 drives the large wheel 642 to rotate and drives the primary shaft 644 to rotate.

[0046] The primary shaft 644 is connected to the gear component 65 , and when the small wheel 641 is directly driven by the servo motor 41 , the synchronous belt 643 can drive the large wheel 642 and the primary shaft 644 to rotate.

[0047] As for the gear component 65, it includes gear 2 651 and gear 3 652, wherein gear 2 651 is fixed on the outer side of the primary shaft 644, so that gear 2 651 and the primary shaft 644 rotate synchronously, gear 3 652 is meshed with the bottom of gear 2 651, and gear 2 651 is fixed on one end of the transmission shaft 61, thereby driving the transmission shaft 61 and other structures to rotate.

[0048] Since the gear 2 651 is meshed with the gear 3 652 , when the gear 2 651 is driven by the primary shaft 644 , the gear 3 652 can drive the transmission shaft 61 , the gear 1 62 and the rack 63 to work.

[0049] To lubricate the reduction assembly 42, in one embodiment, Figure 1 As shown, the dual-axis platform hollow servo positioner also includes a self-lubricating component 7, which is arranged on the base 1. The self-lubricating component 7 forms a negative pressure during the displacement of the protective component 5, and the lubricating oil flows out through the negative pressure, so that the reduction component 42 can be lubricated, forming a lubricating protection for the reduction component 42.

[0050] Further explanation, such as Figure 2 As shown, the self-lubricating component 7 includes a pneumatic component 71 , a lubricating component 72 and a connecting pipe 73 , wherein the pneumatic component 71 is arranged on the base 1 , the lubricating component 72 is arranged at the bottom of the speed reduction component 42 , and the connecting pipe 73 connects the pneumatic component 71 and the lubricating component 72 .

[0051] During use, the gas in the pneumatic component 71 is transferred to the lubricating component 72 when the protective component 5 is displaced, so that the lubricating oil in the lubricating component 72 can flow out to lubricate the gear four 422 and the gear five 423 in the reduction assembly 42.

[0052] Specifically, Figure 5 As shown, in one embodiment, the air pressure component 71 includes an air pressure box 711, an air plug 712 and a connecting rod 713, wherein the air pressure box 711 is fixed on the base 1, the air plug 712 is movably arranged in the air pressure box 711, and the connecting rod 713 is fixedly connected to the protective component 5, for example, Figure 3 The connecting rod 713 shown is fixedly connected to the boss 53, so that when the protective component 5 is displaced, the connecting rod 713 can drive the air plug 712 to move, and by changing the amount of gas in the air pressure box 711, the lubricating component 72 lubricates the deceleration component 42.

[0053] Likewise, if Figure 5 As shown, the lubricating component 72 includes a lubrication box 721 and an oil outlet pipe 722 , wherein one end of the oil outlet pipe 722 is located at the oil inlet 424 , and the other end thereof is disposed in the lubrication oil in the lubrication box 721 .

[0054] When the gas in the air pressure box 711 is introduced into the lubrication box 721, the lubricating oil can flow from the oil outlet pipe 722 into the outer cover 421 to lubricate the gear four 422 and the gear five 423 in the reduction assembly 42, thereby reducing wear. The lubrication box 721 is arranged at the bottom of the outer cover 421 to receive excess lubricating oil, forming an oil circuit closure to avoid waste of lubricating oil.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
