[0027] Please refer to Figures 1 to 2 The electric-driven rotary grinding mechanism 100 shown in the first embodiment of the present invention includes a support frame 110, a rotary motor 120, a grinding assembly and a limiting assembly 150.

[0028] Fixed platforms are formed at both ends of the support frame 110, one end is used to fix the rotating motor 120, and the other end is used to fix the electric-driven rotating grinding mechanism 100, or to be connected to the robot to cooperate with the robot to more flexibly adjust the grinding angle and grinding position.

[0029] The housing of the rotating motor 120 is fixed to one of the fixed platforms along a first direction. The grinding assembly includes a grinding motor 130 fixedly connected to the rotating motor 120 along a second direction, and a grinding wheel 140 mounted on the output shaft of the grinding motor 130. In this embodiment, the first and second directions are perpendicular to each other to facilitate adjustment of the grinding angle. Of course, the angle between the first and second directions can also be other angles and can be set as needed, which is not specifically limited here.

[0030] The limiting assembly 150 is formed between the rotating motor 120 and the grinding assembly. The limiting assembly 150 includes a limiting ring 156 fixedly connected to the outer shell of the grinding motor 130, a limiting wheel 155 fixedly connected to the output shaft of the rotating motor 120, and a limiting bar 151 arranged along the first direction.

[0031] Among them, the limiting ring 156 is sleeved on the limiting wheel 155, and a first limiting block 1561 is formed in the radial direction of the limiting ring 156, and a plurality of second limiting blocks 1551 are arranged at intervals in the circumferential direction of the limiting wheel 155. Limiting grooves 1552 of different sizes are formed between the plurality of second limiting blocks 1551. The first limiting block 1561 extends into the largest limiting groove 1552, and the limiting bar 151 is configured to move along the first direction to extend into or exit the remaining limiting grooves 1552. By rotating the motor 120, the limiting wheel 155 is driven to rotate in the limiting ring 156, so that the first limiting block 1561 moves in the largest limiting groove 1552 to adjust the position of the grinding wheel 140, and the limiting bar 151 extends into one of the remaining limiting grooves 1552 to abut against the second limiting block 1551 to position the grinding wheel 140, or the first limiting block 1561 abuts against the second limiting block 1551 to position the grinding wheel 140, thereby achieving the position of the grinding wheel 140 being adjusted as needed.

[0032] In this embodiment, the limiting wheel 155 is provided with three second limiting blocks 1551, with three limiting grooves 1552 formed between the three second limiting blocks 1551. By driving the limiting wheel 155 forward and reverse, the limiting strip 151 and the first limiting block 1561 respectively abut against the sides of the three second limiting blocks 1551, thereby enabling the grinding wheel 140 to switch between six positions, thereby achieving automatic multi-position adjustment of the grinding wheel 140. Of course, in other embodiments, the number of second limiting blocks 1551 can also be other, and this can be set as needed, and is not specifically limited here.

[0033] In this embodiment, the limiting assembly 150 further includes a driving member 152 mounted on the support frame 110. The driving member 152 is connected to the limiting bar 151 to drive the limiting bar 151 to move in a first direction to extend into or out of the limiting slot 1552. The driving member 152 is a pneumatic cylinder that extends and contracts to drive the limiting bar 151 to move into or out of the limiting slot 1552, thereby facilitating automated positioning of the grinding wheel 140.

[0034] In this embodiment, the limiting assembly 150 further includes a guide assembly, which includes a slide rail 153 fixed to the support frame 110 and a slider 154 slidably connected to the slide rail 153. The slider 154 is fixedly connected to the limiting bar 151. The guide assembly is provided to guide the movement direction of the limiting bar 151 and, at the same time, to securely fix the limiting bar 151, thereby improving the positioning effect of the grinding wheel 140.

[0035] In this embodiment, the limiting strip 151 is disposed below the limiting ring 156. The limiting ring 156 is formed with a retaining groove 1562. When the limiting block extends into the limiting groove 1552, the slider 154 is received in the retaining groove 1562. The retention of the slider 154 in the retaining groove 1562 further enhances the fixing effect of the limiting strip 151, thereby improving the positioning effect of the grinding wheel 140.

[0036] In this embodiment, the grinding assembly further includes a connecting structure comprising a fixing base 123 connected to the grinding motor 130 and a connecting block 122 connected between the fixing base 123 and the output shaft of the rotary motor 120. The connecting block 122 is fixedly connected to the output shaft of the rotary motor 120 and the fixing base 123, respectively, thereby improving the fixing effect between the output shaft of the rotary motor 120 and the grinding assembly.

[0037] In this embodiment, the fixing base 123 includes a fixing base 1231 connected to the connecting block 122 and a fixing cover 1232 detachably connected to the fixing base 1231. A receiving groove 1233 for holding the grinding motor 130 is formed between the fixing base 1231 and the fixing cover 1232. The detachable connection between the fixing base 1231 and the fixing cover 1232 facilitates installation and removal of the grinding motor 130.

[0038] In this embodiment, the connection block 122 is fixedly connected to the limiting wheel 155 , thereby further improving the fixing effect between the output shaft of the rotating motor 120 and the grinding assembly.

[0039] The present application drives the grinding wheel 140 to rotate by the grinding motor 130 to grind the workpiece, and drives the grinding motor 130 to rotate by the rotating motor 120 to adjust the position of the grinding wheel 140 to grind different positions of the workpiece, thereby realizing automatic adjustment of the grinding position, improving grinding efficiency and reducing grinding costs, and setting a limit assembly 150 between the rotating motor 120 and the grinding motor 130, and drives the limit wheel 155 to rotate in the limit ring 156 by the rotating motor 120, so that the first limit block 1561 moves in the largest limit groove 1552 to adjust the position of the grinding wheel 140, and the limit bar 151 extends into one of the remaining limit grooves 1552 to abut against the second limit block 1551 to position the position of the grinding wheel 140, or the first limit block 1561 abuts against the second limit block 1551 to position the position of the grinding wheel 140, thereby improving the stability of the grinding wheel 140.
