Technical Field

[0001] This utility model relates to the technical field of steel reinforcement cage welding devices, and in particular to a cage traction device used in an automatic welding station for box girder steel reinforcement cages. Background Technology

[0002] Reference Figure 1 As shown, during the welding process of the box girder reinforcement cage, several longitudinal bars need to be welded parallel to the U-shaped stirrups along the outline of the U-shaped stirrups.

[0003] In the welding of the steel reinforcement cage of the box girder, the welding of U-shaped stirrups and longitudinal bars is usually completed by a multi-axis robot in an automated welding workstation.

[0004] However, the multi-axis robot is fixed in its installation position within the automated welding station. As the welding process proceeds, the entire box girder steel reinforcement skeleton needs to be moved along the axial direction of the longitudinal reinforcement so that the multi-axis robot can weld and install several stirrups in the axial direction of the longitudinal reinforcement.

[0005] Therefore, how to move the steel reinforcement cage of the box girder within an automated welding workstation is an urgent problem to be solved. Utility Model Content

[0006] In view of the above problems, this utility model provides a skeleton traction device for use in an automatic welding station for box girder steel skeleton, the purpose of which is to realize the traction of the box girder steel skeleton.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A skeleton traction device for use in an automatic welding station for box girder reinforcement skeletons includes: a slide rail, disposed within the automatic welding station; a slide block, slidably disposed on the slide rail; a guide seat, detachably mounted on the slide block; a clamping assembly, disposed on the guide seat, for clamping the end of each longitudinal reinforcement bar; and a driving assembly for driving the slide block to move linearly on the slide rail.

[0008] Furthermore, the clamping assembly includes: a plurality of clamping holes, corresponding to each longitudinal rib, formed within the clamping assembly for the end of the longitudinal rib to pass through; a plurality of threaded holes, corresponding to each clamping hole, formed within the clamping assembly, with one end of the threaded hole connected to the clamping hole; and a limiting screw, installed within the threaded hole via a threaded connection, with one end of the limiting screw used to abut against the longitudinal rib.

[0009] Furthermore, the central axis of the clamping hole is perpendicular to the central axis of the threaded hole.

[0010] Furthermore, the clamping assembly includes: several first clamping blocks distributed on both sides of the guide seat, each first clamping block having a clamping hole and a threaded hole; second clamping blocks and third clamping blocks, strip-shaped, distributed on the bottom side of the guide seat, each having several clamping holes and several threaded holes.

[0011] Furthermore, the drive assembly includes: a servo motor mounted on a slide; a meshing gear and rack, the gear being mounted on the output shaft of the servo motor, and the rack being mounted on one side of the slide rail parallel to the central axis of the longitudinal rib.

[0012] Furthermore, the drive assembly includes: a plurality of rollers that can roll in contact with the slide rail and are rotatably mounted on the slide block.

[0013] Furthermore, the device also includes a bracket, on which a slide rail is mounted.

[0014] The beneficial effects of this utility model are as follows: by using this utility model, the longitudinal rib and the multi-axis robot can be pulled to generate relative displacement, so that the multi-axis robot can weld a number of U-shaped stirrups along the axial direction of the longitudinal rib; moreover, it can also meet the clamping requirements of longitudinal ribs with different distribution conditions, thereby improving the applicability of this utility model.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 2 and Figure 3 As shown in the embodiment of this application, a skeleton traction device for an automatic welding station for box girder reinforcement skeletons includes: a slide rail 21, disposed inside the automatic welding station; a slide seat 22, slidably disposed on the slide rail 21; a guide seat 23, detachably mounted on the slide seat 22; a clamping assembly, disposed on the guide seat 23, for clamping the end of each longitudinal reinforcement bar; and a driving assembly for driving the slide seat 22 to move linearly on the slide rail 21.

[0023] In practical use, this device is installed in an automatic welding station, next to a multi-axis robot. The longitudinal ribs to be welded are threaded one by one into the clamping assembly, which clamps the longitudinal ribs. Then, the drive assembly is activated, which drives the slide block 22 to slide on the slide rail 21, thereby pulling the longitudinal ribs and the multi-axis robot to generate relative displacement, so that the multi-axis robot can weld several U-shaped stirrups along the axial direction of the longitudinal ribs.

[0024] It is worth mentioning that any commercially available multi-axis robot can be used. Welding stirrups using a multi-axis robot is also a well-known technology in this field, and this utility model has not made any creative contribution to it, so it will not be elaborated here.

[0025] Specifically, the clamping assembly includes: a plurality of clamping holes 31, corresponding to each longitudinal rib, which are opened in the clamping assembly for the end of the longitudinal rib to pass through; a plurality of threaded holes 32, corresponding to each clamping hole 31, which are opened in the clamping assembly, and one end of the threaded hole 32 is connected to the clamping hole 31; and a limiting screw, which is installed in the threaded hole 32 by threaded connection, and one end of the limiting screw is used to abut against the longitudinal rib.

[0026] When it is necessary to clamp the longitudinal rib, insert the end of the longitudinal rib into the clamping hole 31, and then the operator turns the limiting screw. Under the threaded transmission, the end of the limiting screw touches the longitudinal rib, clamping the longitudinal rib in the clamping hole 31.

[0027] Preferably, the central axis of the clamping hole 31 is perpendicular to the central axis of the threaded hole 32, and the screw vertically clamps the longitudinal rib.

[0028] It is worth mentioning that the longitudinal ribs can also be positioned through the clamping holes 31. For each longitudinal rib, several pneumatic grippers are set on the guide seat 23 to clamp the longitudinal ribs.

[0029] Continue to refer to Figure 3 As shown, the clamping assembly includes: a plurality of first clamping blocks 41, distributed on both sides of the guide seat 23, each of the first clamping blocks 41 having a clamping hole 31 and a threaded hole 32; second clamping blocks 42 and third clamping blocks 43, which are strip-shaped and distributed on the bottom side of the guide seat 23, each having a plurality of clamping holes 31 and a plurality of threaded holes 32.

[0030] It is worth mentioning that the first clamping block 41 is installed on the guide seat 23 by welding, and the second clamping block 42 and the third clamping block 43 are detachably installed on the guide seat 23 by bolts. For longitudinal bars with different distribution at the bottom of the U-shaped stirrup 1, the staff can replace different second clamping blocks 42 and / or third clamping blocks 43 to meet the clamping requirements of the longitudinal bars.

[0031] Combination Figure 4 and Figure 5 As shown, the guide seat 23 is also detachably mounted on the slide seat 22 by bolts. The staff can change the distribution of the first clamping block 41 by replacing different guide seats 23 to meet the clamping requirements of longitudinal bars with different distributions.

[0032] Specifically, the drive assembly includes: a servo motor mounted on the slide 22; a meshing gear 51 and a rack 52, the gear 51 being mounted on the output shaft of the servo motor, and the rack 52 being mounted on one side of the slide rail 21 parallel to the central axis of the longitudinal rib.

[0033] When the guide seat 23 needs to be moved, the output shaft of the servo motor rotates, which drives the gear 51 to move along the distribution path of the rack 52; in addition, changing the rotation direction of the output shaft of the servo motor can change the movement direction of the guide seat 23.

[0034] Specifically, the drive assembly includes: a plurality of rollers 53, which can roll in contact with the slide rail 21 and are rotatably mounted on the slide block 22.

[0035] It is worth mentioning that the roller 53 is rotatably mounted on the rotating shaft via a bearing, and the rotating shaft is fixedly mounted on the slide 22.

[0036] Specifically, the device also includes: a bracket 6, with a slide rail 21 mounted on the bracket 6, which can be directly bolted to the ground or bolted to other frames.
