[0024] The prior art installs a lubricating oil tank on the top of the slide, and moves the moving block back and forth to squeeze the self-lubricating mechanism at the bottle mouth of the lubricating oil tank, so that the lubricating oil drips onto the screw rod in the moving block for lubrication. However, the back and forth movement of the moving block will cause wear to the oil outlet of the self-lubricating mechanism and the moving block itself, and the oil output of the lubricating oil tank is lubricated by the moving contact with the moving block, which is not stable. Therefore, a mechanical arm lubrication mechanism that can stably lubricate the movement of the mechanical arm is needed.
[0025] like Figure 1-3 As shown, the device includes a robot body 1, a lubrication mechanism 2 is provided outside the robot body 1, and a connection mechanism 3 is provided inside the lubrication mechanism 2. The lubrication mechanism 2 can be used to add lubricating oil to the moving block 201 and the screw rod 102 in the robot body 1, and the connection mechanism 3 can facilitate the installation of the lubricating oil tank 206 on the top of the moving block 201.
[0026] First, the specific structure of the lubrication mechanism 2 is disclosed. The lubrication mechanism 2 includes a moving block 201. An oil injection channel 202 is opened inside the moving block 201. A separator 203 is fixedly installed in the middle of the inner wall of the oil injection channel 202. The separator 203 can separate the injected lubricating oil. A connecting sleeve 204 is fixedly installed on the top of the oil injection channel 202. A permeable leakage plate 205 is installed on the inner wall of the connecting sleeve 204. A lubricating oil tank 206 is installed inside the connecting sleeve 204. The permeable leakage plate 205 can allow the lubricating oil leaked from the lubricating oil tank 206 to drip slowly.
[0027] The robot arm body 1 includes a mounting frame 101, the inner wall of which is rotatably mounted a screw rod 102, which can be threadedly mounted on a moving block 201, a grabbing arm 103 is mounted at the bottom of the moving block 201, and a plurality of holes 4 are provided at the bottom of the inner wall of the oil injection channel 202, which can allow lubricating oil to flow to the contact surface between the moving block 201 and the screw rod 102.
[0028] The moving block 201 is threadedly connected to the outer surface of the screw rod 102, and the screw rod 102 is driven by a motor, so that the moving block 201 can drive the grabbing arm 103 of the robot body 1 to move left and right to adjust the position. The moving block 201 reciprocates on the screw rod 102 and needs to be filled with lubricating oil. A lubricating oil tank 206 is placed on the top of the installation frame 101 where the screw rod 102 is rotatably installed, so that the lubricating oil tank 206 can be installed to the inside of the connecting sleeve 204 through the connecting mechanism 3. A hose is installed on the top of the lubricating oil tank 206 to replenish the lubricating oil inside. The lubricating oil flows out of the bottom of the lubricating oil tank 206 to the connecting sleeve 204. The inside of the connecting sleeve 204 and the penetration leakage plate 205 on the inner wall of the connecting sleeve 204 can make the lubricating oil penetrate and drip slowly, thereby controlling the flow rate of the lubricating oil. The dripping lubricating oil falls on the separator 203, and the separator 203 separates the lubricating oil into two parts, which flow into the oil filling channels 202 on both sides of the separator 203. The lubricating oil is circulated to the threaded contact surface of the moving block 201 and the screw rod 102 through the multiple holes 4 in the oil filling channels 202. The moving block 201 moves to evenly spread the lubricating oil on the outer surface of the screw rod 102, thereby achieving the effect of stably and evenly filling the lubricating oil into the robot body 1.
[0029] The improvement of this embodiment is that through the structure of the penetration leakage plate 205 and the oil filling channel 202, the effect of stably and evenly filling the screw rod 102 and the moving block 201 of the robot body 1 is achieved, which solves the problem of unstable and uneven filling of the robot arm lubricating oil in the prior art.
[0030] Since the lubricating oil tank 206 in the prior art is installed in the moving block 201 to fill the lubricating oil, Figure 4 A second embodiment of the present utility model is shown.
[0031] The specific structure of the connecting mechanism 3 is disclosed again. The connecting mechanism 3 includes a connecting port 301, which is fixedly installed at the bottom of the lubricating oil tank 206. A clamping block 302 is fixedly installed on the outer surface of the connecting port 301. The clamping block 302 is clamped in a groove opened on the inner wall of the connecting sleeve 204. The connecting port 301 connects the lubricating oil tank 206 and the connecting sleeve 204.
[0032] By means of the clamping block 302 fixedly installed on the outer surface of the connecting port 301, the lubricating oil tank 206 can be installed on the top of the connecting port 301, and the connecting port 301 is inserted into the "L"-shaped clamping groove provided on the inner wall of the connecting sleeve 204. The connecting port 301 can be inserted and rotated to install the lubricating oil tank 206, thereby achieving the effect of quickly installing the lubricating oil tank 206 into the moving block 201 at the bottom of the connecting sleeve 204 and filling it with lubricating oil.
[0033] The improvement of this embodiment is that through the structure of the connecting port 301 and the clamping block 302, the lubricating oil tank 206 can be quickly installed into the moving block 201, solving the problem of complicated lubricating oil filling of the robot arm in the prior art.
[0034] In summary, the working principle of this solution is as follows:
[0035] The moving block 201 is threadedly connected to the outer surface of the screw rod 102, and the screw rod 102 is driven by a motor, so that the moving block 201 can drive the grabbing arm 103 of the robot body 1 to move left and right to adjust the position. The moving block 201 reciprocates on the screw rod 102 and needs to be filled with lubricating oil. A lubricating oil tank 206 is placed on the top of the installation frame 101 where the screw rod 102 is rotatably installed, and the lubricating oil tank 206 can be installed to the inside of the connecting sleeve 204 through the connecting mechanism 3. A hose is installed on the top of the lubricating oil tank 206 to replenish the lubricating oil inside. The lubricating oil flows out of the bottom of the lubricating oil tank 206 to the inside of the connecting sleeve 204. The infiltration leakage plate 205 on the inner wall of the connecting sleeve 204 is provided with multiple layers of small holes, so that the lubricating oil can slowly penetrate and drip, and the flow rate of the lubricating oil can be controlled. The dripping lubricating oil falls on the separator 203, and the separator 203 divides the lubricating oil into two parts, and flows into the oil injection channels 202 on both sides of the separator 203. The lubricating oil flows to the contact surface of the thread of the moving block 201 and the screw rod 102 through the multiple holes 4 in the oil injection channels 202. The moving block 201 moves to evenly apply the lubricating oil on the outer surface of the screw rod 102, so as to achieve the effect of stably and evenly filling the lubricating oil into the robot body 1;
[0036] By means of the clamping block 302 fixedly installed on the outer surface of the connecting port 301, the lubricating oil tank 206 can be installed on the top of the connecting port 301, and the connecting port 301 is inserted into the "L"-shaped clamping groove provided on the inner wall of the connecting sleeve 204.
