[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a robotic arm for machining, including a fixed base 1 and a drive base 2 installed at the upper middle part of the fixed base 1. A robotic arm body 3 is rotatably mounted on the drive base 2, and a workpiece chuck 4 is installed on the robotic arm body 3. The drive base 2 is provided with a drive device for driving the robotic arm body 3 to rotate. After the drive device inside the drive base 2 is started, it provides power to the robotic arm body 3, driving it to perform rotation and other actions. The robotic arm body 3 drives the workpiece chuck 4 at the end to move, realizing machining operations such as clamping, handling, loading and unloading of the workpiece.

[0026] The mounting base 1 is equipped with a heat dissipation assembly, which includes a heat dissipation plate 5 and a cooling pipe 7. The cooling pipe 7 is located inside the heat dissipation plate 5. The two ends of the cooling pipe 7 are connected to an inlet pipe 71 and an outlet pipe 72, respectively. Both the inlet pipe 71 and the outlet pipe 72 are equipped with connecting flanges 73. The cooling pipe 7 has a spiral design. The bottom of the drive base 2 is in close contact with the upper end of the heat dissipation plate 5. An external cooling medium (such as coolant) is drawn by a water pump. The coolant enters the spiral cooling pipe 7 inside the heat dissipation plate 5 from the inlet pipe 71. Because the bottom of the drive base 2 is in close contact with the heat dissipation plate 5, the cooling medium in the cooling pipe 7 can efficiently absorb the heat generated by the drive equipment. The cooled medium after absorbing heat is discharged through the outlet pipe 72.

[0027] Heat dissipation fins 21 are installed on the outer wall of the drive base 2 to increase the contact area with air and help dissipate heat;

[0028] A mounting groove 6 is provided in the middle of the upper surface of the mounting base 1, and the heat sink 5 is placed in the mounting groove 6;

[0029] The heat sink 5 has a receiving groove 8 inside, and the cooling pipe 7 is located in the receiving groove 8. The receiving groove 8 is spiral in shape and matches the shape of the cooling pipe 7.

[0030] Extension blocks 51 are fixedly installed at both ends of the heat sink 5. The liquid inlet pipe 71 and the liquid outlet pipe 72 pass through the extension blocks 51 respectively to protect the liquid inlet pipe 71 and the liquid outlet pipe 72.

[0031] The upper surface of the mounting base 1 has grooves 61 on both sides that communicate with the mounting slot 6. Two extension blocks 51 are placed in the grooves 61 respectively to facilitate the positioning and installation of the heat sink 5.

[0032] The upper surface of the fixed base 1 is provided with four sets of bolt holes 12 at equal intervals around the circumference, and the outer wall of the drive base 2 is provided with four mounting plates 22 at equal intervals around the circumference. Each mounting plate 22 is screwed with a bolt 23 that matches the bolt hole 12 for fixing the drive base 2.

[0033] Mounting holes 13 are equidistantly opened on the upper surface of the fixed base 1, and a shock-absorbing pad 11 is provided at the bottom of the fixed base 1 to reduce the vibration generated when the robot is working and ensure the stability of operation.

[0034] The working principle of this embodiment:

[0035] Step 1: Fix the entire robotic arm device to the designated position of the machining equipment through the mounting holes 13 on the fixed base 1. After the drive device inside the drive base 2 is started, it provides power to the main body 3 of the robotic arm, driving it to rotate and perform other actions. The main body 3 of the robotic arm drives the workpiece chuck 4 at the end to move, realizing the machining operations such as clamping, handling, loading and unloading of the workpiece. The drive base 2 is connected to the bolt holes 12 on the fixed base 1 through the mounting plate 22 on the outer wall, and is tightened by bolts 23 to ensure that the drive base 2 is stably connected to the fixed base 1 during operation.

[0036] Step 2: The heat dissipation components work synchronously. The external cooling medium (such as coolant) is drawn by the water pump. The coolant enters the spiral cooling pipe 7 inside the heat dissipation plate 5 from the inlet pipe 71. Since the bottom of the drive seat 2 is in close contact with the heat dissipation plate 5, the cooling medium in the cooling pipe 7 can efficiently absorb the heat generated by the drive equipment. The cooled medium after absorbing heat is discharged through the outlet pipe 72. At the same time, the heat dissipation fins 21 on the outer wall of the drive seat 2 increase the contact area with the air, which helps to dissipate heat and together ensures that the drive equipment operates stably at a suitable temperature.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
