Description

Technical Field

[0001] The present application relates to the field of metal processing technology, and in particular to an immersion manipulator for treating the outer surface of a bearing. Background Art

[0002] Blackening of metal parts is a key surface corrosion protection process. Its core is to chemically form a dense oxide film on the metal surface, thereby blocking air from contact with the substrate and achieving rust prevention. The typical process includes degreasing, pickling, oxidation, and saponification, with immersion being the key step in forming a uniform oxide layer.

[0003] The traditional bearing immersion process has quality defects. That is, bubbles are easily generated during the immersion process, which will hinder the full contact between the solution and the surface of the parts, thus affecting the immersion effect. Alternatively, a stacking method is used to improve the immersion efficiency, so that the parts are in contact with each other. In this case, the contact surface will block the contact of the solution. In addition, the parts are prone to collision, which can easily cause damage to the formed coating and affect the reaction uniformity. At the same time, most existing immersion methods are manual hooking, which is prone to untimely discharge. In addition, the immersion chemical solution is toxic, and long-term exposure is harmful to the health of workers. Based on this, there is an urgent need for an efficient and flexible immersion manipulator structure to achieve simultaneous immersion processing of multiple bearings and improve the immersion efficiency of the bearings.

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0031] Refer to the following Figures 1 to 12 An immersion robot for treating the outer surface of a bearing provided in accordance with some embodiments of the present application is described.

[0032] like Figure 1-12 As shown, the immersion manipulator for bearing outer surface treatment provided in accordance with some embodiments of the present application includes a manipulator assembly 1, a mounting assembly 2, a support assembly 3, a transposition assembly 4, a positioning assembly 5, a docking assembly 6, and a bearing 7. The mounting assembly 2 is rotatably connected to the end of the manipulator assembly 1. The mounting assembly 2 includes: a mounting cylinder 23 for supporting and fixing the bearing 7; a support assembly 3 disposed inside the mounting assembly 2 and rotatably connected to the mounting assembly 2; a plurality of transposition assemblies 4 disposed on the mounting cylinder 23 for fixing the bearing 7; a positioning assembly 5 disposed on the mounting cylinder 23; and a plurality of docking assemblies 6 disposed on the manipulator assembly 1 for connecting and fixing the mounting assembly 2 to the support assembly 3.

[0033] It should be noted that the robotic arm assembly 1 serves as the supporting structure of the entire robotic arm, giving the robotic arm higher flexibility; the mounting assembly 2 and the supporting assembly 3 are movably connected, and the docking assembly 6 is used to adjust the mounting assembly 2 and the supporting assembly 3 between the movable and fixed states; the positioning assembly 5 is used to accurately reset the position between the mounting assembly 2 and the supporting assembly 3 to improve the accuracy of subsequent processing; the main function of the transposition assembly 4 is to fix the bearing 7.

[0034] When the immersion robot for treating the outer surface of the bearing is operating, the bearing 7 to be immersed is fixed by the transposition component 4, and the robot arm component 1 controls the movement of the installation cylinder 23 to make it enter the solution to be immersed, and rotate to make the bearing 7 evenly immersed in the liquid. After the immersion is completed, the positioning component 5 makes the installation component 2 and the support component 3 return to their initial positions, thereby controlling the docking component 6 to fix the installation component 2 and the support component 3. At the same time, the robot arm component 1 controls the installation component 2 and the support component 3 to drive the bearing 7 to rotate, thereby realizing centrifugal dehydration treatment of the bearing 7, and preventing the residual solution of the previous solution from entering the next immersion solution to cause mixing.

[0035] In some possible embodiments, such as Figure 1 As shown, the robotic arm assembly 1 includes: a base 11; a rotating base 12, which is arranged on the base 11; a first robotic arm 13, which is rotatably connected to the rotating base 12; a second robotic arm 14, which is rotatably connected to the first robotic arm 13; a third robotic arm 15, which is rotatably connected to the second robotic arm 14; a fourth robotic arm 16, which is rotatably connected to the third robotic arm 15; and a rotating motor 17, which is arranged at the end of the fourth robotic arm 16.

[0036] In this embodiment, the base 11 serves as the supporting foundation of the entire robotic arm assembly 1 to ensure the stability of the robotic arm during operation; the rotating base 12 provides a rotation basis for the first robotic arm 13, the second robotic arm 14, the third robotic arm 15 and the fourth robotic arm 16, and the robotic arms can swing within a certain range, so that the end manipulator of the robotic arm assembly 1 can perform more precise movements; the rotating motor 17 is arranged at the end of the fourth robotic arm 16, and is used to drive the robotic arm assembly to perform various rotation movements, so that the robotic arm assembly 1 can perform precise movements.

[0037] In some possible embodiments, such as Figure 2-5 As shown, the mounting assembly 2 includes: a hanger 22 fixedly connected to the mounting tube 23; a center column 21 movably engaged and arranged inside the hanger 22; and a plurality of docking columns 24 arranged between the hanger 22 and the rotating motor 17.

[0038] In this embodiment, if Figure 12 As shown, the hanger 22 serves as the main supporting structure to support the dynamic load that may be generated by the entire installation assembly 2; the mounting tube 23 is fixedly connected to the hanger 22 by means of bolts to ensure the firmness of the connection; the center column 21 engages and moves inside the hanger 22, and the connection state between them can be adjusted; the docking column 24 is connected between the hanger 22 and the rotating motor 17, and plays the role of transmitting power and realizing relative movement between the two. The number of docking columns 24 is designed according to actual needs to ensure that the rotating motor 17 can stably and efficiently drive the hanger 22 and the mounting tube 23.

[0039] In some possible embodiments, such as Figure 3 As shown, the installation assembly 2 further includes: a plurality of guide bars 2301 , which are arranged outside the installation cylinder 23 .

[0040] In this embodiment, a plurality of guide bars 2301 are arranged outside the mounting cylinder 23, that is, when the mounting cylinder 23 rotates in the solution, the guide bars 2301 outside thereof move accordingly, and the guide bars 2301 will produce a certain disturbance effect on the surrounding solution.

[0041] In some possible embodiments, such as Figure 2 、 Figure 4 As shown, the support assembly 3 includes: a connecting frame 31, fixedly connected to the center column 21; a connecting plate 32, fixedly connected to the connecting frame 31; a plurality of supporting feet 33, fixedly connected to the connecting plate 32; an upper sealing cover 34, fixed to the outside of the connecting frame 31, and rotatably connected to the mounting cylinder 23; a lower sealing cover 35, fixedly connected to the connecting plate 32, and rotatably connected to the mounting cylinder 23; the upper sealing cover 34 and the lower sealing cover 35 are arranged on the top cover and bottom cover of the mounting cylinder 23.

[0042] In this embodiment, the connecting frame 31 is fixed to the bottom end of the central column 21, and the central column 21 serves as the central support point of the entire support assembly 3; the connecting plate 32 connects the connecting frame 31 and the supporting foot 33 together, and serves as the supporting base for the upper sealing cover 34 and the lower sealing cover 35; the supporting foot 33 is the bottom supporting structure of the support assembly 3, and is magnetic in itself. Most solution containers are made of metal, and the magnetic supporting foot 33 is used to contact the container to improve the stability of the device during operation; and the upper sealing cover 34 and the lower sealing cover 35 can rotate flexibly in the mounting tube 23.

[0043] In some possible embodiments, such as Figure 6 、 Figure 7 As shown, the shifting assembly 4 includes: a plurality of rotating frames 41, which are arranged on the mounting cylinder 23; a secondary bevel gear 42, which is fixedly connected to the rotating frame 41; two rotating hooks 43, which are fixedly arranged at both ends of the rotating frame 41; a limiting hook 44, which is arranged on the mounting cylinder 23 and has a space between it and the rotating hook 43; a main bevel gear 45, which is fixedly arranged on the connecting frame 31 and meshed with the secondary bevel gear 42.

[0044] The secondary bevel gear 42 rotates with the mounting cylinder 23 and moves along the main bevel gear 45. The secondary bevel gear 42 will rotate and the rotating hook 43 will rotate accordingly, making the bearing 7 dynamic, which helps to eliminate bubbles in the bearing 7 during the immersion process, thereby improving the immersion effect of the bearing 7.

[0045] In some possible embodiments, such as Figure 8 As shown, the positioning assembly 5 includes: a first positioning sensor 51, which is arranged on the upper sealing cover 34; a second positioning sensor 52, which is arranged on the mounting tube 23; the first positioning sensor 51 and the second positioning sensor 52 work together.

[0046] In this embodiment, the first positioning sensor 51 is used to sense the position of the upper sealing cover 34, so that it can capture the displacement or rotation dynamics of the upper sealing cover 34. By docking the first positioning sensor 51 with the second positioning sensor 52, the upper sealing cover 34 is restored to its initial position in the mounting tube 23, thereby restoring the external rotating hook 43 of the mounting tube 23 to its initial position, thereby improving the positioning accuracy.

[0047] In some possible embodiments, such as Figure 9-10 As shown, the docking assembly 6 includes: a sealing seat 61, which is arranged outside the rotating motor 17; an air connection pipe 6101, which is arranged on the sealing seat 61; a piston tube 62, which is arranged inside the sealing seat 61; and a piston column 63, which is connected to the piston tube 62.

[0048] In this embodiment, the gas connection pipe 6101 serves as an interface for connecting to an external gas source; the piston tube 62 provides a sliding track for the piston column 63, and the piston column 63 can perform reciprocating motion therein by controlling the gas input.

[0049] In some possible embodiments, such as Figure 9 、 Figure 11 As shown, the docking assembly 6 further includes: a docking block 64 fixedly connected to the piston tube 62 ; a docking protrusion 65 fixedly disposed on the outside of the center column 21 ; and the docking block 64 engaged with the outside of the docking protrusion 65 .

[0050] In this embodiment, the docking block 64 is fixed to the end of the piston column 63, and the docking protrusion 65 is set on the center column 21. The docking block 64 is driven to move by the piston column 63, so that multiple docking blocks 64 contact and engage with the docking protrusion 65, thereby fixing the center column 21. This method can quickly separate or connect the center column 21.

[0051] In some possible embodiments, such as Figure 7 、 Figure 8 As shown, the bearing 7 is arranged on the rotating hook 43 and between the limiting hook 44.

[0052] In this embodiment, the bearings 7 are placed on corresponding rotating hooks 43, and multiple rotating hooks 43 are evenly arranged on the outside of the mounting cylinder 23, that is, the mounting cylinder 23 can perform immersion treatment on multiple bearings 7 in one batch at the same time. Compared with processing the bearings 7 one by one, this batch processing method significantly improves the immersion efficiency, reduces the processing time, and thus improves the overall processing efficiency.

[0053] When the immersion manipulator with the outer surface treatment of the bearing is in operation, the rotating hook 43 is rotated to a horizontal state, and the space between the rotating hook 43 and the limiting hook 44 is increased, so that the bearing 7 that needs to be immersed can be placed on the rotating hook 43. The manipulator assembly 1 adjusts the position through a multi-stage rotating structure, namely the rotating seat 12, the first manipulator 13, the second manipulator 14, the third manipulator 15 and the fourth manipulator 16, so that the mounting cylinder 23 enters the immersion solution, and the magnetic support foot 33 contacts the bottom of the solution container and is fixed, thereby starting the rotating motor 17 and driving the mounting cylinder 23 to rotate in the solution. Due to the setting of the guide bar 2301, it can cause disturbance to the surrounding solution, which helps the bearing 7 to be evenly immersed in the liquid, and then the secondary bevel gear 42 rotates with the installation cylinder 23, driving the rotating hook 43 and the bearing 7 to rotate to achieve uniform immersion. After the immersion is completed, the first positioning sensor 51 docks with the second positioning sensor 52, so that the rotating hook 43 is in a vertical state, reducing the space between it and the limit hook 44, so that the robotic arm assembly 1 controls the installation cylinder 23 to rise and lift it above the immersion solution. The piston tube 62 inputs gas to make the piston column 63 drive the docking block 64 to move, so that it engages with the docking protrusion 65, thereby fixing the center column 21 and the main bevel gear 45. The rotating motor 17 rotates to generate centrifugal force to dehydrate the bearing 7 and prevent residual solution from entering the next immersion solution to cause mixed liquid, thereby achieving efficient treatment of the bearing 7.
