[0027] The positioning mechanism includes a first positioning member and a second positioning member respectively connected to the fixed seat 3 and the movable seat 4 for positioning the transverse reinforcement 1;

[0028] The fixing mechanism includes a second electric push rod 601 fixedly connected to the top of the fixing seat 3 , and a positioning seat 602 fixedly connected to the output end of the second electric push rod 601 for limiting the longitudinal steel bar 2 .

[0029] The first positioning member includes a supporting plate 501 and a positioning plate 502 fixedly connected to the top of the fixing seat 3, the outer wall of the supporting plate 501 is provided with a through hole, and the outer wall of the positioning plate 502 is provided with a positioning groove, wherein the central axis of the through hole coincides with the central axis of the positioning groove.

[0030] The first positioning member also includes a receiving groove opened on the top of the fixing seat 3, a first electric push rod 503 fixedly connected to the bottom of the receiving groove, and a limit plate 504 fixedly connected to the output end of the first electric push rod 503. By starting the first electric push rod 503, the limit plate 504 is driven to move, thereby blocking the opening of the through hole and achieving the fixation of the transverse steel bar 1.

[0031] The second positioning member has the same structure as the first positioning member, and the second positioning member is arranged on the top of the movable seat 4 .

[0032] By passing the transverse steel bar 1 through the through hole and making the end face of the transverse steel bar 1 abut against the inner wall of the positioning groove of the positioning plate 502, the other end of the transverse steel bar 1 is flush with the outer surface of the load-bearing plate 501, and then starting the first electric push rod 503, thereby driving the limit plate 504 to move, so as to block the opening of the through hole and fix the transverse steel bar 1.

[0033] Embodiment 2: Figure 1-4 As shown, a cold-rolled ribbed steel bar welding mesh fixing device includes a transverse steel bar 1, a longitudinal steel bar 2 arranged above the transverse steel bar 1, a fixing seat 3 arranged below the transverse steel bar 1, and a movable seat 4 arranged on the side of the fixing seat 3, and also includes a positioning mechanism arranged below the transverse steel bar 1, and a fixing mechanism arranged on the outer side wall of the longitudinal steel bar 2;

[0034] The positioning mechanism includes a first positioning member and a second positioning member respectively connected to the fixed seat 3 and the movable seat 4 for positioning the transverse reinforcement 1;

[0035] The fixing mechanism includes a second electric push rod 601 fixedly connected to the top of the fixing seat 3 , and a positioning seat 602 fixedly connected to the output end of the second electric push rod 601 for limiting the longitudinal steel bar 2 .

By rotating the fixing pin 607, the clamping plate 605 is pushed to move, thereby stretching the connecting spring 606. When the fixing pin 607 is detached from the clamping plate 605, the clamping plate 605 will move upward under the action of the connecting spring 606.

[0041] When the transverse reinforcement 1 is fixed, the second electric push rod 601 is controlled according to the diameter of the reinforcement to adjust the height of the positioning seat 602. When the height adjustment is completed, the longitudinal reinforcement 2 is inserted into the positioning seat 602 and placed horizontally. At this time, the bottom surface of the longitudinal reinforcement 2 will contact the top surface of the transverse reinforcement 1. Then, the fixing pin 607 is rotated and the clamping plate 605 is pushed down until the clamping plate 605 is against the top of the longitudinal reinforcement 2, thereby fixing the longitudinal reinforcement 2.

After welding is completed, the fixing pin 607 is rotated and separated from the clamping plate 605. At this time, the clamping plate 605 will move upward under the action of the connecting spring 606, and then the second electric push rod 601 is started to extend, and the user holds the other end of the longitudinal steel bar 2, thereby driving the welded steel bar to move upward until the transverse steel bar 1 is separated from the through hole, and then the servo motor 608 is started, so that the servo motor 608 drives the ball screw 609 to rotate, thereby driving the movable seat 4 to make a linear motion. When it moves to the rotating position, the operation of Example 1 is repeated to fix the other transverse steel bar 1, and then the transverse steel bar 1 is welded to the bottom of the longitudinal steel bar 2 to form a welding network.
