A robot arm rotating joint 3 is installed at the center of the back of the U-shaped support 1.
[0025] The specific installation process of the above embodiment is as follows: one metal ring of the workpiece placing basket 2 is placed on the top of the U-shaped support 1, at this time the U-shaped support 1 supports the workpiece placing basket 2; the two side air cylinders 5 are started through the switch, the air cylinder 5 pushes the moving table 6 to move on the guide rail 7, during the movement of the guide rail 7, the rack 8 meshes with the gear 9, thereby driving the rotating shaft 10 to rotate, the movable pin 11 on the top rotates synchronously, and finally abuts against the metal ring of the workpiece placing basket 2, forming a clamping effect, while the movable pin 11 is fixed, the movable pin 11 also moves into the clamping groove 13 on the side of the clamping block 12, forming a limiting and fixing effect, avoiding falling off, when disassembly is needed, the air cylinder 5 is controlled to reset, the rack 8 and the gear 9 mesh reversely, driving the rotating shaft 10 to drive the movable pin 11 to reverse and orient to the side of the workpiece placing basket 2, and the workpiece placing basket 2 can be dismounted from the U-shaped support 1.
[0026] As shown in Figure 1 , in order to further improve the fixing effect of the clamp, the rack 8, the gear 9, the rotating shaft 10 and the movable pin 11 are provided with two groups on the same side of the side wall of the U-shaped support 1, the two racks 8 are cross and oppositely arranged along the moving direction of the moving table 6; the movable pins 11 are symmetrically arranged on the top of the side wall of the same side of the U-shaped support 1; the clamping blocks 12 are provided with clamping grooves 13 on the two sides for clamping cooperation with the two movable pins 11, by arranging two groups of the rack 8, the gear 9, the rotating shaft 10 and the movable pin 11 on the same side of the moving table 6, and the directions of the two racks 8 are opposite, when the moving table 6 is pushed to move on the guide rail 7 by the air cylinder 5, the two gears 9 rotate in opposite directions, at this time the two movable pins 11 on the top rotate synchronously, and finally the four movable pins 11 fix the side of the workpiece placing basket 2, and the two sides of the clamping block 12 are provided with the clamping groove 13, so that the two sides of the clamping block 12 can limit the two movable pins 11, by increasing the number of movable pins 11 and increasing the fixed contact area, the fixing effect is further improved.
[0027] As shown in Figure 3 , in order to improve the preliminary fixing effect of the U-shaped support 1, the middle and both sides of the top of the U-shaped support 1 are provided with clamping blocks 12; the movable pins 11 and the clamping blocks 12 are arranged on the top of the limiting block 14, and the rotating shaft 10 penetrates the limiting block 14; the side of the limiting block 14 facing the workpiece placing basket 2 is provided with a circular arc-shaped groove, when the workpiece placing basket 2 is placed on the U-shaped support 1, the metal ring placed on the top of the U-shaped support 1 is clamped in the circular arc-shaped grooves of the plurality of limiting blocks 14, and this structure can avoid horizontal displacement of the workpiece placing basket 2 and improve the preliminary fixing effect.
[0028] As shown in Figure 1 , the clamping block 12 is fixed on the top of the limiting block 14 by bolts, which facilitates dismounting of the clamping block 12.
[0029] As shown in Figure 2As shown, in order to further improve the safety of the fixture, detachable side plates 4 are installed on both sides of the side wall of the U-shaped bracket 1. By setting the side plates 4, the cylinder 5, moving table 6, guide rail 7, rack 8, gear 9 and rotating shaft 10 are hidden in the side wall of the U-shaped bracket 1, so as to avoid production accidents and improve safety.
[0030] Example 2:
[0031] like Figure 4 As shown, this application also provides a robotic arm for the above-mentioned metal processing handling fixture, wherein the output end of the robotic arm 15 is connected to the U-shaped bracket 1 via a robotic arm rotary joint 3.
[0032] During handling, the U-shaped bracket 1 is fixed to the output end of the robot arm 15 by rotating the joint 3. Then, a metal ring of the workpiece placement basket 2 is placed on the top of the U-shaped bracket 1. After the fixation is completed by the above-mentioned fixture structure, the robot arm 15 is driven to carry out the transfer of the metal parts. During the transfer, the fixture structure on the U-shaped bracket 1 can ensure the stability of the workpiece placement basket 2 and avoid the workpiece falling due to shaking of the workpiece placement basket 2. Compared with the existing metal parts handling, the handling robot arm with fixture fixation has a more stable effect.
