Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3A damping and resetting auxiliary mechanical arm for disassembling and assembling a shield machine cutter is shown, comprising a movable base 1, a main support arm 2 is hinged on the top of the movable base 1, an L-shaped auxiliary support arm 3 is hinged on one end of the main support arm 2, a clamp 11 is provided at the bottom of the L-shaped auxiliary support arm 3, a direction adjustment component is provided at the connection between the clamp 11 and the L-shaped auxiliary support arm 3, a first spring damper 4 for pulling the L-shaped auxiliary support arm 3 toward the side of the main support arm 2 is symmetrically hinged on the front and back sides of the main support arm 2, and a second spring damper 5 for resetting the main support arm 2 is hinged on one side of the main support arm 2.

[0020] Specifically, the two first spring dampers are symmetrically hinged on the front and back sides of the L-shaped secondary support arm 3 .

[0021] It should be noted that the first spring damper 4 and the second spring damper 5 are both memory spring dampers. In the absence of human operation, they will slowly move to the initial installation position by themselves to free up working space for construction personnel; the L-shaped secondary support arm 3 is made of aluminum alloy square steel with a thickness of 2mm, a length of 50mm and a width of 50mm. It is connected to the main support 2 through a joint bearing and is provided with a set of two first spring dampers 4. The spring damper torque is set to be adjustable at 20-40kgf. The tail is fixed on the main support arm 2, and the upper and lower radius rotation of the L-shaped secondary support arm 3 is achieved through the positioning pin.

[0022] Furthermore, when the positions of the main support arm 2 and the L-shaped auxiliary support arm 3 are changed due to the use of the staff, the spring in the elastic damping block is pulled and deformed. When the use is over, the main support arm 2 and the L-shaped auxiliary support arm 3 are reset by restoring the deformation through the spring in the elastic damper. Through this design, the space originally occupied by the mechanical arm can be quickly vacated, making it convenient for construction workers to lift out the tool.

[0023] Specifically, the top of the movable base 1 is symmetrically fixedly connected with arc blocks 6 , and the second spring damper 5 is arranged on the opposite side of the two arc blocks 6 .

[0024] Specifically, a sliding groove 8 is provided in the middle of the arc block 6 , and the front and back sides of the second spring damper 5 are symmetrically fixedly connected with sliding blocks 7 , which are slidably inserted and connected inside the sliding groove 8 .

[0025] It should be noted that the movable base 1 is designed with a main support arm damper sliding rail with an arc, which can assist the main support arm to move up and down 63°, so that it can accept a larger working angle.

[0026] Furthermore, when one end of the second spring damper 5 needs to move, the second spring damper 5 drives the sliding block 7 to move in the sliding groove 8 on the arc block 6 .

[0027] Specifically, a caliper 10 is provided on one side of the movable base 1 , and an I-beam 9 for limiting the moving direction and distance of the caliper 10 is slidably interlaced with one side of the caliper 10 .

[0028] It should be noted that the caliper 10 is composed of a caliper, a locating pin, a locating pin bearing, and a sliding roller, and is installed on a sliding I-beam 9. Six sets of sliding rollers are provided in the walking area of ​​the caliper 10. When the robotic arm is under force, the caliper 10 can be easily moved on the guide rail of the I-beam 9 to adapt to various angle adjustments for tool removal and replacement. The I-beam 9 is set in an I-shape, and the caliper 10 slides on one side of the I-beam 9. Quick-release locating pins are provided on both sides of the I-beam 9 to limit the moving distance of the robotic arm.

[0029] Specifically, the adjustment assembly includes a connection frame 12 threadedly sleeved on the bottom end of the L-shaped secondary support arm 3 , and a universal ball head 13 is fixedly connected to the top end of the clamp 11 , and the universal ball head 13 is inserted and connected to the inside of the connection frame 12 .

[0030] It should be noted that a threaded thread for fixing the position of the connecting frame 12 is provided at the bottom of the L-shaped auxiliary support arm 3, and a fixing through hole is provided at the end of the threaded thread. When the position of the connecting frame 12 needs to be fixed, the connecting frame 12 is first threadedly sleeved on the outer wall of the threaded thread, and then the positioning pin is installed to lock it, thereby fixing the connecting frame 12 to the bottom end of the L-shaped auxiliary support arm 3; a hole for the universal ball head 13 to pass through is provided at the bottom of the connecting frame 12, and the diameter of the hole is smaller than the diameter of the universal ball head 13, thereby preventing the universal ball head 13 from passing through the connecting frame 12; the clamp 11 is composed of two semi-rings, which can rotate between the two. When the position of the tool needs to be fixed, the tool is first placed between the two semi-rings, and then the other ends of the two semi-rings are fixed by bolts through the side away from the rotating part of the semi-rings, thereby achieving clamping and positioning of the tool through the two semi-rings.

[0031] Specifically, a locking ball head bolt 14 for limiting the rotation of the universal ball head 13 is threadedly inserted and connected to one side of the connection frame 12 .

[0032] It should be noted that the locking ball stud 14 is provided to clamp the universal ball head 13 between the locking ball stud 14 and the inner wall of one side of the connecting frame 12 by squeezing, thereby preventing the position of the universal ball head 13 from changing.
