Description

Technical Field

[0001] The utility model relates to a clamping tooling, in particular to a displacement welding clamping tooling for an extension beam. Background Technique

[0002] The extension beam is an important component of a lifting device, and this component is assembled and welded by steel plates of various different specifications and shapes. Since the design tolerance dimension accuracy requirements of the extension beam are relatively high, there are many types and positions of welding joints involved. In the manufacturing process, a large number of turning operations are required to control welding deformation. The existing turning operation schemes mostly involve workers using a traveling crane for lifting and turning.

[0003] Existing Problems:

[0004] 1. When performing riveting and welding operations, in order to prevent welding deformation and control the overall shape and position tolerance of parts, it is necessary to continuously adjust the welding sequence according to the actual situation. To ensure the weld quality, the weld position needs to be adjusted to the best welding position, and this process requires multiple turning operations. However, there are few traveling cranes in the workshop and they are used frequently. Although the turning operation is fast, the waiting time is long, resulting in a large amount of wasted man-hours.

[0005] 2. Manual operation of the traveling crane for turning is greatly affected by personal subjective factors. Coupled with the fact that this operation requires multiple turnings, the risk probability increases, and it is easy to occur safety accidents, resulting in casualties and damage to the product due to dropping.

After the workpiece is assembled, clamped and fastened with this tooling and connected as a whole, the tooling can be simply and quickly fixed on the displacement machine, and then the tooling is driven to rotate by the rotation torque of the displacement machine, thereby realizing the turning of the workpiece.

[0007] To achieve the above technical purpose, the utility model adopts the following technical scheme: A displacement welding clamping tooling for an extension beam, including a bottom plate, on which a locking screw rod and a root pressing block are bolted respectively for locking the head and root of the extension beam, and a pair of side plate stoppers are also provided for restricting the movement of the side of the extension beam.

[0008] Further, the locking screw rod is provided with a locking baffle and a locking handle.

[0009] Further, the locking screw rod is provided with an adjusting gasket, and the adjusting gasket is located below the locking baffle.

[0010] Further, the locking screw rod is also provided with a limit pin.

[0011] Further, the bottom plate is provided with threaded hole columns, and the locking screw rod is threadedly connected to the threaded hole columns.

[0012] Further, there are two root pressing blocks. The top ends are fastened by a pressing rod, and the bottom ends are fastened to the bottom plate by a fixing plate and bolts.

[0013] Further, a pressing plate is further arranged at the lower part of the root pressing block.

[0014] Further, the bottom plate is provided with waist-shaped holes, and the side plate stoppers are fastened in the waist-shaped holes.

[0015] In summary, the present utility model has achieved the following technical effects:
