When there is a vertical steel bar to be bundled, the moving arm 403a keeps vertical under the action of the pull rope 402d and keeps parallel with the target plane to bundle.

[0071] Embodiment 2

[0072] Reference Figures 1-16For the second embodiment of the present application, the embodiment is based on the previous embodiment, and the difference between the two embodiments is that:

[0073] The steel bar bundling robot for the building machine further comprises a bundling mechanism 500.

[0074] Specifically, the bundling mechanism 500 comprises a cover 501 located outside the telescopic member 404, the cover 501 is internally provided with a wire feeding member 502, the wire feeding member 502 is externally provided with a wire twisting member 503, the wire twisting member 503 is externally provided with a wire cutting member 504, and the cover 501 is externally further provided with a winch 505.

[0076] The surface of the lower disc 502d-1 is annularly and movably embedded with a plurality of locking blocks 502d-3, the top surface of the locking block 502d-3 is upwardly inclined in the clockwise direction, the lower part of the locking block 502d-3 is provided with a supporting spring 502d-4, and the bottom surface of the upper disc 502d-2 is further provided with a groove matched with the locking block 502d-3. When the lower disc 502d-1 rotates in the forward direction of the wire feeding motor 502a, the rotation direction is consistent with the inclination direction of the locking block 502d-3, the upper disc 502d-2 is locked with the lower disc 502d-1 through the locking block 502d-3, so that the upper disc 502d-2 can rotate synchronously with the lower disc 502d-1, and the steel wire is smoothly fed out. When the motor reverses, the top surface of the locking block 502d-3 is pressed into the supporting spring 502d-4 under the action of the upper disc 502d-2 when the lower disc 502d-1 rotates, at this time, the upper disc 502d-2 and the lower disc 502d-1 are in a relative sliding state, that is, the upper disc 502d-2 is relatively stationary, so that the steel wire cannot be fed out. Through the cooperation between the rotation direction of the motor and the locking block 502d-3, the connection state between the upper disc 502d-2 and the lower disc 502d-1 can be controlled, and the purpose of controlling the wire feeding of the wire feeding device 502 is achieved.

[0077] The wire twisting device 503 includes a bevel gear set 503a coaxially arranged at the lower part of the driving tooth 502b, the bevel gear set 503a includes a first bevel gear 503a-1 coaxially arranged at the lower part of the driving tooth 502b, the outer side of the first bevel gear 503a-1 is engaged and matched with a second bevel gear 503a-2, and the outer side shaft center of the second bevel gear 503a-2 is connected with a rotating shaft 503b, the front surface of the rotating shaft 503b is threaded, the front end of the rotating shaft 503b is further connected with a return spring 503c, the other end of the return spring 503c is connected with a fixed seat 503d, the two sides of the front part of the fixed seat 503d are hinged with clamping jaws 503e, the threaded segment of the rotating shaft 503b is further sleeved with a shaft sleeve 503f, the two sides of the front end of the shaft sleeve 503f are integrally provided with push rods 503g, the front end of the push rod 503g is hinged with the inner side end of the clamping jaw 503e, and the outer side of the shaft sleeve 503f is coaxially and fixedly provided with a first friction wheel 503h, and the outer side of the shaft sleeve 503f and the fixed seat 503d is sleeved with an outer cylinder 503i.

[0078] The broken wire piece 504 comprises a second friction wheel 504a which is in close contact with the outer edge of the first friction wheel 503h, the inner side of the second friction wheel 504a is coaxially provided with a rotating sleeve 504b, the front part of the rotating sleeve 504b is provided with a sector-shaped gap, the outer side of the rotating sleeve 504b is provided with a guide cylinder 504c for guiding the extruded steel wire, the inner part of the rotating sleeve 504b is provided with a threaded through slot, the threaded through slot is matched with a screw rod 504d, and the outer edge of the screw rod 504d is symmetrically provided with two cutters 504e which can cooperate with the front gap of the rotating sleeve 504b. When the first friction wheel 503h rotates with the shaft sleeve 503f, the second friction wheel 504a can synchronously rotate, and the thickness of the second friction wheel 504a is smaller than that of the first friction wheel 503h, so that the transmission connection between the first friction wheel 503h and the second friction wheel 504a can be maintained during the rotation and translation of the first friction wheel 503h with the shaft sleeve 503f, thereby ensuring the stable use of the broken wire piece 504. The rotating sleeve 504b is driven to rotate by the second friction wheel 504a, and then the cutters 504e are driven to move into the rotating sleeve 504b by the cooperation of the threaded slot in the rotating sleeve 504b and the screw rod 504d, so that the two cutters 504e can be synchronously retracted by the extrusion force of the front sector-shaped gap of the rotating sleeve 504b during the movement, thereby cutting the steel wire. Through the transmission cooperation between the second friction wheel 504a and the first friction wheel 503h, the twisting and breaking of the steel wire can be simultaneously performed, thereby optimizing the efficiency of the steel bar bundling operation.

[0079] Further, during the wire output stage, the wire output motor 502a rotates forward, at this time the rotating shaft 503b rotates counterclockwise under the transmission of the bevel gear set 503a, at this time the rotating direction is opposite to the direction of the external threads of the rotating shaft 503b, so that the rotating shaft 503b is in an idle state at this time, that is, the shaft sleeve 503f is in a stationary state, and the clamping jaw 503e cannot be retracted and clamped. When the wire output motor 502a reverses, the rotating direction of the rotating shaft 503b matches the direction of the threads, so that the shaft sleeve 503f rotates and moves backward under the cooperation of the threads between the rotating shaft 503b and the shaft sleeve 503f, at this time the inner side end of the clamping jaw 503e moves backward under the pulling of the push rod 503g, so that the front part of the clamping jaw 503e retracts and clamps the steel wire, and the shell of the clamping jaw 503e rotates with the rotating shaft 503b to perform the twisting action. Through the cooperation of the rotating shaft 503b and the threads, the use state of the clamping jaw 503e is controlled under the cooperation of the threads between the rotating shaft 503b and the shaft sleeve 503f, thereby ensuring the smooth performance of the entire twisting process.
