[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] The specific technical solution of this utility model is as follows:

[0018] In one specific embodiment, such as Figure 1 and Figure 2 As shown, this utility model provides an industrial robotic arm joint drive flange, including a drive flange body 1, with an arm flange 2 and an actuator mounting plate 3 respectively connected to both ends of the drive flange body 1.

[0019] The drive flange body 1 has a connecting sleeve 4 and a limiting sleeve 5 in its central hole. The connecting sleeve 4 is integrally connected to the wall of the central hole of the drive flange body 1, and the wall of the connecting sleeve 4 has a plurality of locking ball holes 6 along the circumference. Locking balls 7 are movably installed in the locking ball holes 6. The limiting sleeve 5 is located between the drive flange body 1 and the connecting sleeve 4, and the limiting sleeve 5 is slidably connected to the wall of the central hole of the drive flange body 1. The wall of the central hole of the drive flange body 1 has two symmetrically arranged electric telescopic rods 8. The telescopic end of the electric telescopic rod 8 is fixedly connected to the limiting sleeve 5, and the electric telescopic rod 8 is connected to an external controller.

[0020] The actuator mounting plate 3 is integrally connected with a connecting pipe 9, which is inserted into the connecting sleeve 4. The pipe wall of the connecting pipe 9 is provided with a plurality of locking grooves 10 corresponding one-to-one with the locking beads 7.

[0021] The above solution is adopted: the actuator mounting plate 3 in this utility model is equipped with an end effector, and different end effectors can be replaced by disassembling and assembling the actuator mounting plate 3. The specific operation for installing the actuator mounting plate 3 is as follows: move the actuator mounting plate 3 close to the drive flange body 1 so that the connecting pipe 9 of the actuator mounting plate 3 is inserted into the connecting sleeve 4 of the drive flange body 1 until the connecting pipe 9 is fully inserted, so that the locking groove 10 of the connecting pipe 9 corresponds to the locking ball 7. Then, control the electric telescopic rod 8 to extend and drive the limiting sleeve 5 to move to the outside of the locking ball 7. The limiting sleeve 5 squeezes the locking ball 7 into the corresponding locking groove 10, and the limiting sleeve 5 maintains its current position and prevents the locking ball 7 from exiting from the locking groove 10. Then, the connecting pipe 9 and the actuator mounting plate 3 connected to the connecting pipe 9 are locked by the cooperation of the locking ball 7 and the locking groove 10. The specific operation for removing the actuator mounting plate 3 is as follows: control the electric telescopic rod 8 to retract and drive the limiting sleeve 5 to move away from the outside of the locking ball 7. Then the connecting pipe 9 can be removed from the connecting sleeve 4 to remove the actuator mounting plate 3.

[0022] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the actuator mounting plate 3 is symmetrically provided with two positioning posts 11, and the drive flange body 1 is provided with positioning holes corresponding to the positioning posts 11.

[0023] The above solution is adopted: by setting positioning pins 11 and positioning holes, the positioning between actuator mounting plate 3 and drive flange body 1 is achieved, so that when the connecting pipe 9 of actuator mounting plate 3 is inserted into the position, the locking groove 10 of the connecting pipe 9 can accurately correspond to the locking ball 7.

[0024] In another specific embodiment, such as Figure 1 and Figure 2 As shown, a sealing ring 12 is provided between the drive flange body 1 and the actuator mounting plate 3.

[0025] The above solution, by setting the sealing ring 12, helps to improve the assembly sealing between the actuator mounting plate 3 and the drive flange body 1.

[0026] In another specific embodiment, such as Figure 1 As shown, both the drive flange body 1 and the arm flange 2 are provided with flange holes 13.

[0027] The above solution allows the drive flange body 1 and the arm flange 2 to be fixedly assembled through the flange hole 13 and the bolt and nut assembly.

[0028] In another specific embodiment, such as Figure 1 As shown, the central hole wall of the arm flange 2 is provided with a wiring groove 14.

[0029] The above solution is adopted: wiring channels 14 are set up for laying the lines.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
