Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a cooling device for machining a robotic arm. Background Art

[0002] A robotic arm is a machining device similar to a human arm and is widely used in fields such as industrial assembly and safety explosion protection. It is a complex system with characteristics such as high precision, high flexibility, and strong coupling.

[0003] During the machining of a robotic arm, it is necessary to cut and polish the robotic arm to improve the assembly accuracy. Cutting and polishing will generate cutting heat, and the cutting temperature will cause the machining accuracy to decrease and limit the production efficiency. Therefore, it is necessary to cool the robotic arm during machining to reduce the cutting temperature. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a cooling device for machining a robotic arm to solve the technical problems in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A cooling device for machining a robotic arm includes a machining box. Inside the machining box, there is a liquid storage tank. Inside the liquid storage tank, there are guide rods and a filter screen. On one side of the liquid storage tank, there is a motor and a collection box. The output end of the motor is connected to a reciprocating lead screw. Between the reciprocating lead screw and the guide rod, there is a slider, and an electromagnet is installed at the bottom of the slider. Above the inside of the liquid storage tank, there is a normally open switch. One end of the reciprocating lead screw is connected to a turntable. On one side of the turntable, there is an adjustment frame connected through a rotating column. At the bottom of the adjustment frame, there is a piston rod. On the other side of the liquid storage tank, there is a piston box connected through a connecting pipe. Inside the piston box, there is a piston plate sliding, and the top of the piston plate is connected to the piston rod. On one side of the piston box, there is a delivery pipe.

[0006] Further, check valves are connected to both the delivery pipe and the connecting pipe.

[0007] By adopting the above technical scheme, the check valve can prevent the coolant from flowing back, avoiding air entering the piston box due to the backflow, which may cause the piston box to lose airtightness and affect the practicality of the device.

[0008] Further, the electromagnet is electrically connected to the normally open switch.

[0009] By adopting the above technical scheme, when the slider drives the electromagnet to contact the normally open switch, the normally open switch disconnects the power supply, causing the electromagnet to lose magnetism, and the chips on the electromagnet fall into the slag discharge port. When the slider drives the electromagnet away from the normally open switch, the electromagnet is reconnected to the power supply to start adsorbing the chips.

[0010] Further, a slag discharge port is provided on one side of the liquid storage tank, and the slag discharge port is inclined.

[0011] By adopting the above technical solution, when the waste chips on the electromagnet fall into the slag discharge port, the inclined design helps to quickly remove the waste chips from the liquid storage tank and accelerate the production rate.

[0012] Further, there are two piston rods in total, and the two piston rods are symmetrically distributed.

[0013] By adopting the above technical solution, the symmetrical distribution makes the pressures exerted by the piston rods on both sides of the piston plate the same, avoiding the piston plate from tilting due to uneven force, thus affecting the practicality of the device.

[0014] Further, the length of the electromagnet is equal to the width of the filter screen.

[0015] By adopting the above technical solution, the adsorption range of the electromagnet is increased, so that the electromagnet can adsorb more waste chips and accelerate the production efficiency.

[0016] Further, a workbench is provided inside the processing box, and the top of the workbench is inclined along the direction of the liquid inlet.

[0017] By adopting the above technical solution, when processing the robotic arm, the inclined setting can accelerate the flow rate of the cutting fluid, enabling the cutting fluid to drive the waste chips to quickly flow into the liquid inlet and preventing the waste chips from accumulating on the workbench.

[0018] Further, a gooseneck tube is provided on one side of the top of the workbench, and one end of the delivery pipe is connected to the gooseneck tube.

[0019] By adopting the above technical solution, the cutting fluid in the liquid storage tank is transported into the gooseneck tube through the delivery pipe, and the angle of the gooseneck tube is adjusted so that the nozzle is aligned with the place that needs to be cooled for spraying, and then it is recycled for reuse to reduce resource consumption.

[0020] Further, a guide plate is provided on one side of the filter screen, and the guide plate is inclined, and the guide plate is connected to the slag discharge port.

[0021] By adopting the above technical solution, the waste chips brought by the electromagnet first fall onto the guide plate, then slide into the slag discharge port through the guide plate, and finally the waste chips are discharged into the collection box through the slag discharge port for recycling.

[0022] Further, the adjustment frame is slidably connected to the rotating column.

[0023] By adopting the above technical solution, when processing the robotic arm, the reciprocating lead screw rotates driven by the output end of the motor, so that the turntable drives the connecting column to rotate in the adjustment frame, and the piston rod drives the piston plate to perform a piston motion in the piston box, pumping out the liquid in the liquid storage tank, and cooling the robotic arm through the nozzle on the gooseneck tube.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. In the utility model, a turntable, a rotating column, an adjusting frame, a piston rod, a piston plate and a piston box are provided. When machining the robotic arm, the output end of the motor drives the reciprocating lead screw to rotate, the reciprocating lead screw drives the turntable to rotate, the turntable drives the rotating column to rotate so that the adjusting frame swings up and down, thereby enabling the piston rod to drive the piston plate to perform a piston motion in the piston box, sucking the cutting fluid in the liquid storage tank into the piston box through the connecting pipe, and squeezing the cutting fluid through the delivery pipe into the gooseneck pipe to cool the machining position through the nozzle;

[0026] 2. In the utility model, a normally open switch and an electromagnet are provided. When machining the robotic arm, the output end of the motor drives the reciprocating lead screw to rotate, so that the slider drives the electromagnet to perform a reciprocating motion. The metal waste chips mixed in the cutting fluid are filtered through the filter screen, and the cutting fluid is recycled. Under the action of the normally open switch, the electromagnet is always in an energized state, and thus the electromagnet always maintains magnetism, and can adsorb the debris on the filter screen. When the reciprocating lead screw rotates and drives the slider to move, the slider touches the normally open switch, thereby causing the normally open switch to cut off the power supply to the electromagnet. After the power is cut off, the electromagnet loses magnetism, and the debris adsorbed on its surface is discharged from the slag discharge port. Through this method, the debris on the filter screen can be cleaned at all times, avoiding blockage of the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0034] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0035] Embodiment 1: A cooling device for robotic arm processing, as Figures 1-5 shown, includes a processing box 1. Inside the processing box 1, there is a liquid storage tank 3. Inside the liquid storage tank 3, there are a guide rod 9 and a filter screen 12. On one side of the liquid storage tank 3, there are a motor 7 and a collection box 4. The output end of the motor 7 is connected to a reciprocating screw rod 8. Between the reciprocating screw rod 8 and the guide rod 9, there is a slider 10, and an electromagnet 11 is installed at the bottom of the slider 10. Above the inside of the liquid storage tank 3, there is a normally open switch 14. One end of the reciprocating screw rod 8 is connected to a turntable 15. On one side of the turntable 15, there is a rotating column 16 connected to an adjustment frame 17. The adjustment frame 17 is slidably connected to the rotating column 16. When processing the robotic arm, the reciprocating screw rod 8 rotates driven by the output end of the motor 7, so that the turntable 15 drives the connecting column to rotate inside the adjustment frame 17, and the piston rod 19 drives the piston plate 20 to perform a piston movement inside the piston box 21, pumping out the liquid inside the liquid storage tank 3, and cooling the robotic arm through the nozzle on the gooseneck pipe 6. At the bottom of the adjustment frame 17, there is a piston rod 19. On the other side of the liquid storage tank 3, there is a piston box 21 connected through a connecting pipe 22. Inside the piston box 21, there is a slidable piston plate 20, and the top of the piston plate 20 is connected to the piston rod 19. On one side of the piston box 21, there is a delivery pipe 5.

[0036] Refer to Figure 1 and Figure 3 , in the above embodiment, check valves are connected to both the delivery pipe 5 and the connecting pipe 22. The check valves can prevent the coolant from flowing back, avoiding air entering the piston box 21 due to the backflow, which may cause the piston box 21 to lose its airtightness and affect the practicality of the device.

[0037] Refer to Figure 1 and Figure 3, in the above embodiment, a slag discharge port 13 is provided on one side of the liquid storage tank 3, and the slag discharge port 13 is inclined. When the waste chips on the electromagnet 11 fall into the slag discharge port 13, the inclined design helps to quickly remove the waste chips from the liquid storage tank 3 and accelerate the production rate.

[0038] Refer to Figure 4 and Figure 5 , in the above embodiment, there are two piston rods 19 in total, and the two piston rods 19 are symmetrically distributed. The symmetrical distribution makes the pressures exerted by the piston rods 19 on both sides of the piston plate 20 the same, avoiding the inclination of the piston plate 20 caused by uneven force and thus affecting the practicality of the device.

[0039] Refer to Figure 1 and Figure 3 , in the above embodiment, a workbench 2 is provided inside the processing box 1, and the top of the workbench 2 is inclined along the direction of the liquid inlet 18. When machining the robotic arm, the inclined setting can accelerate the flow rate of the cutting fluid, enabling the cutting fluid to drive the waste chips to quickly flow into the liquid inlet 18 and preventing the waste chips from accumulating on the workbench 2.

[0040] Refer to 1 and Figure 3 , in the above embodiment, a gooseneck tube 6 is provided on one side of the top of the workbench 2, and one end of the delivery pipe 5 is connected to the gooseneck tube 6. The cutting fluid in the liquid storage tank 3 is conveyed into the gooseneck tube 6 through the delivery pipe 5. The angle of the gooseneck tube 6 is adjusted so that the nozzle is aligned with the place that needs to be cooled for spraying, and then it is recycled for reuse to reduce resource consumption.

[0041] Refer to Figure 1 and Figure 3 , in the above embodiment, a guide plate 23 is provided on one side of the filter screen 12, and the guide plate 23 is inclined. The guide plate 23 is connected to the slag discharge port 13. The waste chips brought by the electromagnet 11 first fall onto the guide plate 23 and then slide into the slag discharge port 13 through the guide plate 23, and finally the waste chips are discharged into the collection box 4 through the slag discharge port 13 for recycling.

[0042] Embodiment 2: On the basis of the above Embodiment 1, although the filter screen 12 can filter the cutting fluid, after long-term use, the metal waste chips are likely to block the filter screen 12. Now, by providing the electromagnet 11 and the normally open switch 14, the metal waste chips can be adsorbed by magnetism to clean the filter screen 12.

[0043] Refer to Figure 1 and Figure 3, in the above embodiment, the electromagnet 11 is electrically connected to the normally open switch 14. When the slider 10 drives the electromagnet 11 to contact the normally open switch 14, the normally open switch 14 disconnects the power supply, causing the electromagnet 11 to lose its magnetism. The waste chips on the electromagnet 11 fall into the slag discharge port 13. When the slider 10 drives the electromagnet 11 away from the normally open switch 14, the electromagnet 11 is reconnected to the power supply to start adsorbing the waste chips.

[0044] Referring to Figure 1 and Figure 3 , in the above embodiment, the length of the electromagnet 11 is equal to the width of the filter screen 12, which increases the adsorption range of the electromagnet 11, enabling the electromagnet 11 to adsorb more waste chips and improving the production efficiency.

[0045] The implementation principle of the present utility model is as follows: When machining the robotic arm, the staff starts the motor 7. The output end of the motor 7 drives the reciprocating lead screw 8 to rotate. Driven by the reciprocating lead screw 8, the turntable 15 drives the connecting column to rotate within the adjusting frame 17, causing the adjusting frame 17 to move up and down. Driven by the adjusting frame 17, the piston rod 19 drives the piston plate 20 to move up and down within the piston chamber 21. When the piston plate 20 moves upward, the cutting fluid in the liquid storage tank 3 is sucked into the piston chamber 21 through the connecting pipe 22 by suction. When the piston plate 20 moves downward, the cutting fluid in the piston chamber 21 is transported through the delivery pipe 5 to the gooseneck pipe 6 by pressure. Adjust the angle of the gooseneck pipe 6 so that the nozzle on the gooseneck pipe 6 is aligned with the machining position, and the cutting fluid is sprayed out for cooling;

[0046] At the same time, the cutting fluid mixed with metal waste chips accumulates on the workbench 2 and enters the liquid storage tank 3 through the liquid inlet 18. The filter screen 12 filters it. Driven by the reciprocating lead screw 8, the slider 10 drives the electromagnet 11 to reciprocate on the guide rod 9. When the electromagnet 11 is energized, it generates magnetism, and the metal waste chips on the filter screen 12 are adsorbed by the magnetism of the magnet. When the electromagnet 11 contacts the normally open switch 14, the normally open switch 14 causes the electromagnet 11 to disconnect the power supply and lose its magnetism, so that the metal waste chips fall onto the guide plate 23. The metal waste chips slide to the waste residue port through the guide plate 23 and finally enter the collection box 4. When the electromagnet 11 is driven by the slider 10 to leave the normally open switch 14, it is connected to the power supply to obtain magnetism.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments according to their needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
