Robotic arms are widely used in many fields, including manufacturing, medical surgery, space exploration, and service robots in daily life. In the manufacturing industry, robotic arms are often used for various operations such as assembly, handling, welding, painting, and packaging. They can work continuously, improve production efficiency, and reduce labor costs. In addition, through programming, robotic arms can complete complex and precise tasks with high stability and repeatability.

[0003] When performing rotational motions, robotic arms often rely on bearings to achieve smooth rotation. However, in harsh processing environments, bearings may be damaged due to the intrusion of dust or other tiny debris. These contaminants may impair the accuracy and performance of the bearings, resulting in unstable operation or reduced efficiency of the robotic arm. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a robot arm bearing protection device, which solves the problem that the bearings may be damaged due to the invasion of dust or other tiny debris in harsh processing environments. These contaminants may damage the accuracy and performance of the bearings, resulting in unstable operation or reduced efficiency of the robot arm.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanical arm bearing protection device, comprising a base plate, a support seat connected to the base plate, two bearings connected inside the support seat, the two bearings are connected to the same rotating shaft, the rotating shaft is connected to the mechanical arm body outside, the support seat is connected to a protection device, the protection device is connected to a lubrication device, the protection device comprises two connecting plates, an upper shell is connected below the connecting plate, two fixed plates are connected outside the upper shell, a slide plate is connected below the fixed plate, a locking plate is slidably connected outside the slide plate, the two locking plates are connected to the same lower shell, a card block is slidably connected inside the slide plate, a return spring is connected inside the card block, and sealing sleeves are connected to both the upper shell and the lower shell.

[0007] As a further solution of the utility model: the rotating shaft is rotatably connected in the sealing sleeve, the clamping block is clamped under the locking plate, and the lower shell is connected in the supporting seat.

[0008] As a further solution of the utility model: the lubricating device comprises an oil tank, the oil tank is connected to the connecting plate, a grip rod is slidably connected inside the oil tank, and a sealing plug is connected under the grip rod.

[0009] As a further solution of the utility model: a leakage hole is opened in the oil tank, and the sealing plug is clamped on the leakage hole.

[0010] As a further solution of the utility model: a pipeline is connected under the leakage hole, and the pipeline corresponds to the position of the bearing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The mechanical arm bearing protection device is provided with a connecting plate, an upper shell, a fixing plate, a slide plate, a locking plate, a lower shell, a block, a pull-back spring and a sealing sleeve. When protection is needed, the upper shell is aligned with the lower shell, and then the slide plate is clamped in the locking plate. At this time, the locking plate applies an extrusion force to the block, and the extrusion drives the block to slide in the slide plate. Then, when the block is away from the locking plate, the pull-back spring applies an elastic force to the block, and the elastic force drives the block to move, so that it can be quickly reset. At this time, the block is clamped under the locking plate, and then the connecting plate can be installed on the support seat by bolts. At this time, when the mechanical arm body drives the rotating shaft to rotate, the rotating shaft will rotate through the sealing sleeve, thereby shielding the bearing and avoiding the damage of the bearing due to the invasion of dust or other tiny debris in harsh processing environments. These pollutants may damage the accuracy and performance of the bearing, resulting in unstable operation or reduced efficiency of the mechanical arm.

[0013] 2. The bearing protection device of the robotic arm is provided with an oil tank, a grip rod, a sealing plug, a leak hole and a pipeline. When lubrication is required at the connection between the bearing and the rotating shaft, lubricating oil is injected into the oil tank, and then the grip rod is pulled, which drives the sealing plug to move, and then the sealing plug moves away from the leak hole. Then the lubricating oil flows from the leak hole into the pipeline and drips on the connection between the bearing and the rotating shaft. After the grip rod is pulled up for a certain period of time, pressure is applied to the grip rod so that the sealing plug is stuck in the leak hole, thereby achieving lubrication of the connection between the bearing and the rotating shaft.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a mechanical arm bearing protection device, including a base plate 1, a support seat 2 is connected to the base plate 1, two bearings 3 are connected inside the support seat 2, the same rotating shaft 7 is connected inside the two bearings 3, the rotating shaft 7 is connected to a mechanical arm body 4 outside, a protection device 5 is connected inside the support seat 2, a lubricating device 6 is connected to the protection device 5, the lubricating device 6 includes an oil tank 61, the oil tank 61 is connected to the connecting plate 51, a gripping rod 62 is slidably connected inside the oil tank 61, a sealing plug 63 is connected under the gripping rod 62, a leakage hole 64 is opened in the oil tank 61, the sealing plug 63 is clamped on the leakage hole 64, a pipe 65 is connected under the leakage hole 64, and the pipe 65 is connected to the bearing 3 positions, the protective device 5 includes two connecting plates 51, the connecting plates 51 are installed on the support seat 2, the pull-back spring 58 is connected in the slide plate 54, the rotating shaft 7 is rotatably connected in the sealing sleeve 59, the clamping block 57 is clamped under the locking plate 55, the lower shell 56 is connected in the support seat 2, the connecting plate 51 is connected under the upper shell 52, the upper shell 52 is connected to two fixing plates 53 outside, the fixing plate 53 is connected under the slide plate 54, and the slide plate 54 is slidably connected to the locking plate 55 outside. By setting the slide plate 54 and the locking plate 55, the slide plate 54 cooperates with the locking plate 55, so that the locking plate 55 limits the slide plate 54, so as to prevent the slide plate 54 from being separated from the locking plate 55 during the processing;

[0022] The two locking plates 55 are connected to the same lower shell 56, and the slide plate 54 is slidably connected to a card block 57, and the card block 57 is connected to a pull-back spring 58. By setting the pull-back spring 58, when processing, the pull-back spring 58 applies elastic force to the card block 57 to keep it stable. When the card block 57 is away from the locking plate 55, the pull-back spring 58 applies elastic force to the card block 57, and the elastic force drives the card block 57 to move, so that it can be quickly reset.

[0023] The upper shell 52 and the lower shell 56 are both connected with a sealing sleeve 59. By arranging the sealing sleeve 59 and the rotating shaft 7, the sealing sleeve 59 cooperates with the rotating shaft 7, so that the sealing sleeve 59 can rotate the rotating shaft 7 without affecting the sealing effect.

[0024] The working principle of the utility model is:

[0025] When protection is needed, the upper shell 52 is aligned with the lower shell 56, and then the slide plate 54 is clamped in the locking plate 55. At this time, the locking plate 55 applies an extrusion force to the block 57, and the extrusion drives the block 57 to slide in the slide plate 54. Then, when the block 57 is away from the locking plate 55, the return spring 58 applies an elastic force to the block 57, and the elastic force drives the block 57 to move, so that it can be quickly reset. At this time, the block 57 is clamped under the locking plate 55, and then the connecting plate 51 can be installed on the support seat 2 by bolts. At this time, the mechanical arm body 4 drives the rotating shaft 7 to rotate When the bearing 3 and the rotating shaft 7 are moving, the rotating shaft 7 will rotate through the sealing sleeve 59. When it is necessary to lubricate the connection between the bearing 3 and the rotating shaft 7, the lubricating oil is injected into the oil tank 61, and then the grip 62 is pulled, and the grip 62 drives the sealing plug 63 to move, and then the sealing plug 63 moves away from the leakage hole 64. Then the lubricating oil flows into the pipe 65 from the leakage hole 64 and drips on the connection between the bearing 3 and the rotating shaft 7. After pulling up the grip 62 for a certain period of time, pressure is applied to the grip 62, so that the sealing plug 63 is stuck in the leakage hole 64. At this point, the protection of the bearing 3 and the lubrication of the connection between the bearing 3 and the rotating shaft 7 are completed.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
