[0003] Currently, angle grinders are mainly operated by hand, and the operator adjusts the grinding angle and position of the angle grinder by hand. The entire grinding and cutting operation is greatly interfered with by human factors. The operating accuracy and effect of different operators are also uneven, and the processing difficulty is very difficult to control. The angle grinder controlled by a robotic arm needs to be equipped with a special robotic arm, which is not only expensive, but also has low applicability and great limitations. Summary of the Invention

[0008] The upper surface of the lower assembly frame is provided with a transverse adjustment guide rail of an integrated structure, and an electrically controlled translation screw rod is movably assembled inside the transverse adjustment guide rail.

[0009] An internal thread translation block matched with the electric control translation screw rod is provided on the adjusting surface at the lower end of the upper assembly frame.

[0010] An internal thread adjustment hole is provided on the outer side of the annular assembly frame, and a lateral locking bolt is inserted into the internal thread of the internal thread adjustment hole.

[0011] An annular adjustment groove and a strip-shaped adjustment groove are provided on the outer side of the control handle.

[0012] An annular rotary switch is elastically assembled inside the annular adjustment groove, and a bar-shaped horizontal push switch is elastically assembled inside the bar-shaped adjustment groove.

[0013] An optical recognition module and an infrared monitoring probe are installed on the outer side surface of the lateral transmission seat.

[0014] An inner extrusion frame is installed at the extrusion end of the lateral locking bolt.

[0015] The beneficial effects of the present invention are:

[0026] Figure 1 、 Figure 2 and Figure 3 The electric control handle of an angle grinder shown in the figure includes an annular assembly frame 1 for being mounted on the body of the angle grinder. The outer surface of the annular assembly frame 1 has an external guide ring 2 with an integral structure. An annular external adjustment cover 3 is slidably mounted on the outer side of the external guide ring 2. The outer side of the annular external adjustment cover 3 has a lower assembly frame 4 with an integral structure. An upper assembly frame 5 is slidably mounted on the upper end of the lower assembly frame 4. The outer end of the upper assembly frame 5 has a control handle 6.

[0027] In order to cooperate with the electronic control adjustment and assembly, the outer arc surface of the annular external adjustment cover 3 is provided with a lateral transmission seat 7 of an integral structure.

[0028] In order to coordinate with the angle control, an electrically controlled worm 8 is movably mounted inside the lateral transmission seat 7 and meshes with the external guide ring 2 .

[0029] The outer guide ring 2 is located on the annular worm gear, which is engaged with the electric-controlled worm 8. The electric-controlled worm 8 rotates to drive the lateral transmission seat 7 and the annular outer adjustment cover 3 to rotate along the outer guide ring 2.

[0030] In order to cooperate with translation adjustment, the upper surface of the lower assembly frame 4 has an integrated transverse adjustment guide rail 9, and an electric-controlled translation screw rod 10 is movably installed inside the transverse adjustment guide rail 9.

[0031] In order to cooperate with the screw adjustment, the lower end adjustment surface of the upper assembly frame 5 is provided with an internal thread translation block 51 that cooperates with the electric control translation screw 10.

[0032] In order to facilitate installation and adjustment, an internal thread adjustment hole is opened on the outer side of the annular assembly frame 1, and a lateral locking bolt 11 is threadedly inserted into the internal thread adjustment hole.

[0033] In order to facilitate the assembly of the switch, an annular adjustment groove and a strip-shaped adjustment groove are provided on the outer side of the control handle 6 .

[0035] The electric-controlled worm 8 is controlled by rotating the annular rotary switch 12, and the electric-controlled worm 8 is used to control the rotation and adjustment of the external guide ring 2 that is engaged with it; by squeezing and pushing the bar-shaped translation switch 13, the electric-controlled translation screw 10 is controlled to rotate forward and reverse, thereby changing the position of the internal thread translation block 51 inside the horizontal adjustment guide rail 9, thereby adjusting the relative positions of the lower assembly frame 4 and the upper assembly frame 5.

[0036] In order to cooperate with optical monitoring, an optical recognition module 14 and an infrared monitoring probe 15 are installed on the outer side surface of the lateral transmission seat 7.

[0037] The optical recognition module 14 is an optical camera, which displays the video data of the operating position on the display screen located on the upper assembly frame 5 at close range through the optical camera, so that people can observe the operating position at close range. The infrared monitoring probe 15 determines the force applied by scanning the temperature changes on the grinding disc of the angle grinder. The greater the force applied, the higher the temperature of the grinding position.

[0038] In order to improve the assembly and locking firmness, an inner extrusion frame 16 is installed at the extrusion end of the lateral locking bolt 11.

[0039] A metal extrusion base is fixed on the outer side of the inner extrusion frame 16 , and a metal extrusion block that matches the metal extrusion base is axially fixed to the inner end of the lateral locking bolt 11 .
