Clamping structure for barrel and trough welding equipment

Abstract

This invention discloses a clamping structure for a barrel / tank welding equipment, which is assembled below the platform of the equipment. It includes a hanger, a traction mechanism, a first gripper mechanism, a second gripper mechanism, and a power source. The hanger is connected to the platform and suspended below it. The traction mechanism and the first gripper mechanism are respectively assembled on the hanger. The second gripper mechanism is connected to the power source and is respectively assembled on the first gripper mechanism. Through this structure, a single power source drives the first and second gripper mechanisms to clamp the workpiece for welding.

The first gripper arm is positioned at a preset location; a second gripper mechanism is positioned on the first gripper mechanism, comprising: a second rigid rail, positioned on the first gripper base; a second slide, slidably mounted on the second rigid rail; a second gripper base, upright on the second slide; a second gripper assembly, comprising: a second gripper arm, horizontally positioned and mounted on the second gripper base; and a plurality of second grippers, each positioned at a preset location on the second gripper arm; and a power source, positioned in one of the upright sections, not overlapping with the configuration of the first gripper assembly, and connected to the second gripper base, selectively tractioning the second gripper base to move.

2. The clamping structure for the tank welding equipment as described in claim 1, wherein the hanger assembly is provided with a traction mechanism, comprising: A guide frame is assembled on one side of the assembly plate and has a plurality of stop portions formed at both ends of the guide frame; A stop block is disposed between each of the stop parts and moves in tandem with the horizontal section; a guide rod extends through the stop block and is respectively connected to each of the stop parts at both ends; and a plurality of elastic members are respectively sleeved on the outer periphery of the guide rod and disposed on both sides of the stop block.

3. The clamping structure of the tank welding equipment as described in claim 1, wherein the first claw arm comprises: A first adjusting screw, with threaded sections in opposite directions at its two ends; a first arm section, horizontally arranged and connected to one of the vertical sections, with a preset end face screwed to one end of the first adjusting screw; a second arm section, horizontally arranged and screwed to the other end of the first adjusting screw, and arranged away from the first arm section; and a first limiting rod, one end of which is attached to the second arm section, and the other end of which abuts against the preset end face of the first arm section.

4. The clamping structure of the tank welding equipment as described in claim 1, wherein the second claw arm comprises: A second adjusting screw, with opposite threaded sections at both ends in opposite helical directions; A first arm is horizontally configured and connected to the second gripper seat, and a preset end face is screwed to one end of the second adjusting screw; a second arm is horizontally configured and screwed to the other end of the second adjusting screw, and is configured away from the first arm; and a second limiting rod is configured at one end of the second arm and at the other end against the preset end face of the first arm.

5. The clamping structure of the tank welding equipment as described in claim 1, wherein the assembly plate is connected to a support mechanism, comprising: One extension base, one end of which is connected to the assembly plate; A plurality of support arms, one end of which is respectively mounted on both sides of the extension base, and the other end facing the platform; And a plurality of rollers, each pivotally mounted on the upper section of the respective support arm.

6. The clamping structure of the tank welding equipment as described in claim 1, wherein the hanger is connected to the table via a plurality of guide rail assemblies, wherein each guide rail assembly includes: A plurality of guide rails are symmetrically arranged at preset positions on both sides of the platform, and each guide rail has: a sliding groove section recessed on one end face along the extension direction of each guide rail and a rigid rail section protruding on the lower end face along the extension direction of each guide rail; and a plurality of sliding blocks respectively slidably disposed on the rigid rail section to provide for the assembly of each boom.

7. The clamping structure for the tank welding equipment as described in claim 6, wherein each upper section of the boom is provided with a limiting group including: A baffle plate is attached to the boom at one end and parallel to the slide section at the other end; and a limiting member is screwed onto the baffle plate and abuts against the slide section.
