Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] Please refer to Figure 1 and Figure 2 , the present utility model provides a grease application integrated machine for actuator assembly, including a robotic arm 1, and a support base 11 is fixedly installed at the output end of the robotic arm 1; the support base 11 is used to provide an installation foundation for other components, a grease gun 4 is fixedly installed on the left side of the support base 11, the grease gun 4 is in a can shape and the lower end is conical, and can compact the lubricating grease conveyed inside. The upper end of the grease gun 4 is connected and assembled with an external grease mixer through a delivery pipe 17. During operation, the grease mixer can pump lubricating grease to the grease gun 4 through the delivery pipe 17. The robotic arm 1 is an existing device and can flexibly move the grease gun 4 to a specified position in three-dimensional space and complete the grease application operation by walking along a preset trajectory. The above is the prior art and will not be described in detail here.

[0024] Please refer to Figure 3 , the lower end of the grease gun 4 is inserted and assembled with an adapter tube 14. The lower end of the outer circumference of the adapter tube 14 is provided with a hemispherical head 12. The adapter tube 14 is sleeved with a spring 13, and the spring 13 abuts between the grease gun 4 and the hemispherical head 12; the spring 13 is used to generate a downward resetting force on the hemispherical head 12. Correspondingly, the adapter tube 14 can slide adaptively in the grease gun 4.

[0025] A support frame 6 is fixedly installed on the left side of the grease gun 4. The lower end of the support frame 6 is rotatably installed with a turntable 7 through a bearing. A hemispherical groove is formed on the upper side of the turntable 7, and the hemispherical grooves are evenly distributed in a circumferential manner. The hemispherical head 12 abuts against one of the hemispherical grooves. A nozzle 3 communicating with the hemispherical groove is installed on the lower side of the turntable 7. A driving assembly 5 for rotating the turntable 7 is installed on the left side of the support frame 6; the turntable 7 can be rotated through the driving assembly 5, and in cooperation with the hemispherical head 12 that can move up and down, the adapter pipe 14 can be connected and docked with different nozzles 3 to change the output mode of the grease.

[0026] Specifically, the nozzle 3 includes a connecting pipe 34 and an arc-shaped output pipe 31, a claw-shaped output pipe 32, and a single-point output pipe 33 that are respectively and communicatively installed at the lower end of the connecting pipe 34. The number of hemispherical grooves is three. The upper end of the connecting pipe 34 is respectively connected and assembled with the hemispherical groove in a threaded connection manner. The threaded connection method facilitates the installation and disassembly of the connecting pipe 34, making maintenance or replacement operations more convenient.

[0027] A first output port is evenly formed on the inner arc of the arc-shaped output pipe 31. The grease output from the arc-shaped output pipe 31 through the first output port is distributed in an arc shape on the vertical plane, which is conducive to greasing at the horizontal shaft component (such as the motor output end); the lower ends of the claw heads (3 to 6 distributed in a circumferential manner) of the claw-shaped output pipe 32 are respectively provided with second output ports. The grease output from the claw-shaped output pipe 32 through each second output port is distributed in a circumferential shape on the horizontal plane, which is conducive to greasing at the vertical shaft component (such as the pin shaft); the lower end of the single-point output pipe 33 is provided with a third output port. The grease output from the single-point output pipe 33 through the third output port can form a characteristic planar pattern along the movement track of the grease gun 4, which is conducive to greasing at the mating part of irregular components (such as the worm teeth of a sector worm gear).

[0028] The driving assembly 5 includes a motor 51 and a driven gear 53. The motor 51 is fixedly assembled with the support frame 6. A driving gear 54 is fixedly installed at the output end of the motor 51 through a transmission rod 52. A driven gear 53 is fixedly installed on the upper side of the turntable 7. The driving gear 54 is meshed and assembled with the driven gear 53; the diameter of the driving gear 54 is smaller than that of the driven gear 53, which plays a role in reducing speed and increasing torque. When the motor 51 rotates the driving gear 54 through the transmission rod 52, the turntable 7 can be rotated through the meshed driven gear 53.

[0029] In addition, to ensure the rotational stability of the transmission rod 52, a bearing seat is also fixedly installed on the support frame 6, and the transmission rod 52 is rotatably installed in the bearing seat through a bearing.

[0030] A reference block 16 is fixedly installed on the upper side of the driven gear 53. There are three reference blocks 16 evenly distributed in a circumferential manner, and the three reference blocks 16 are respectively arranged corresponding to the three hemispherical grooves. A first position sensor 15 is fixedly installed on the right side of the support frame 6, and the first position sensor 15 is aligned with one of the reference blocks 16. The first position sensor 15 is used to identify the positions of the three reference blocks 16 in sequence to know which nozzle 3 is currently in use.

[0031] Embodiment 2:

[0032] The present utility model provides another grease - applying all - in - one machine for actuator assembly. The additional technical features based on Embodiment 1 are as follows:

[0033] Please refer to Figure 2 and Figure 4 , a heating component 2 for outputting hot air is installed on the upper side of the robotic arm 1. The heating component 2 includes a hot air blower 21 and a nozzle 24. The hot air blower 21 is fixedly assembled with the robotic arm 1. The output end of the hot air blower 21 is connected and installed with an annular pipe 23 through a metal hose 22. The inner side of the annular pipe 23 is fixedly assembled with a grease gun 4 through a support arm. The lower side of the annular pipe 23 is connected and installed with a nozzle 24. The nozzles 24 are evenly distributed in a circumferential manner, and the output end of the nozzle 24 is inclined and pointed at the turntable 7. When the hot air blower 21 works, the hot air generated is transported to the nozzle 24 through the metal hose 22 and the annular pipe 23 and evenly output. The output hot air blows near the turntable 7, and can heat the grease in the adapter pipe 14 and the grease in the nozzle 3 to prevent the influence of temperature difference on the fluidity of the grease.

[0034] In addition, a temperature sensor is provided on the hot air blower 21. The temperature sensor is electrically connected to the hot air blower 21 through an industrial controller to collect the room temperature of the working area and adaptively adjust the output power of the hot air blower 21, that is, when the room temperature is high, the output power of the hot air blower 21 is low, and vice versa, when the room temperature is low, the output power of the hot air blower 21 is high, so as to ensure that the temperature of the grease at the adapter pipe 14 and the nozzle 3 is around 25°C.

[0035] Please refer to Figure 2 and Figure 3, a collection component 8 is arranged below the support base 11. The collection component 8 includes a containing cup 82 and a pedestal 83. A placement ring 81 is fixedly installed on the left side of the pedestal 83, and the containing cup 82 is placed inside the placement ring 81; when in use, the pedestal 83 is installed on one side of the working area through square steel, without affecting the activity area of normal coating work. When the equipment has not been used for a long time and then resumes operation, the lubricating grease in the adapter pipe 14 and the nozzle 3 will deteriorate in quality. At this time, the robotic arm 1 moves the adapter pipe 14 above the containing cup 82 to perform discharge treatment first, that is, while discharging the lubricating grease, the nozzles 3 are switched one by one to ensure that the lubricating grease in the adapter pipe 14 and each nozzle 3 has normal quality. After completion, the coating operation is carried out; regularly take out the containing cup 82 from the placement ring 81, remove the deteriorated lubricating grease and then put it back.

[0036] A second position sensor 9 is fixedly installed on the upper side of the pedestal 83, and a reference rod 10 is fixedly installed on the lower side of the support base 11; during the process of the robotic arm 1 moving the adapter pipe 14 above the containing cup 82, the reference rod 10 will finally align with the second position sensor 9 to ensure the position accuracy of the adapter pipe 14 after movement.

[0037] Both the first position sensor 15 and the second position sensor 9 adopt inductive position sensors. Correspondingly, the reference block 16 and the reference rod 10 are made of metal materials for the purpose of coordinated use.

[0038] The electrical components such as the robotic arm 1, the motor 51, the hot air blower 21, the first position sensor 15, and the second position sensor 9 are all electrically connected to the industrial host in this process, and are uniformly controlled through the industrial host. Human-machine interaction can also be carried out through the operation interface of the industrial host.

[0039] Now, the working principle will be described with the structure of Embodiment 2:

[0040] When the coating operation is restarted after not being used for a long time, the robotic arm 1 first moves the adapter pipe 14 above the containing cup 82, and at the same time, the mixing machine pressurizes and pumps to first discharge the deteriorated lubricating grease in the adapter pipe 14 and each nozzle 3;

[0041] After completion, the robotic arm 1 moves the adapter pipe 14 above the coating area, switches the corresponding nozzles 3 through the drive assembly 5, and then performs the specific coating action. Since the coating methods of each nozzle 3 are more in line with the shapes of the parts in the coating area, the difficulty of moving the robotic arm 1 can be reduced and the coating efficiency can be improved;

[0042] At the same time, the hot air output by the heating component 2 according to the room temperature can blow near the turntable 7, which can ensure that the lubricating grease has the best fluidity.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
