Abstract
The utility model relates to a kind of pipe end self clamping device, and it belongs to the technical field of automatic welding.This device is provided with two rod cylinder, and its one end is connected with handle, and the other end is provided with contiguous block.Hand propelled handle, drive contiguous block travels forward by cylinder piston rod, and because contiguous block and paw are coupled together by the first connecting pin and the second connecting pin by connecting plate, the 3rd connecting pin is fixing, and paw can rotate around the 3rd connecting pin.Cylinder piston rod travels forward and drives compact heap product piece to be compressed, and reaches self-locking when connecting plate is vertical state.The arrangement increases the precision and stability of mouth of pipe location, decrease percent defective.
Description
Technical field
The utility model relates to a kind of pipe end self clamping device, and it belongs to the technical field of automatic welding.
Background technology
in current domestic automobile gas extraction system frock clamp, mouth of pipe location is generally directly connected with locating shaft or positioning sleeve with cylinder, this structure is when workman's piece installing, workpiece through be everlasting pneumatic clamping time be subjected to displacement, weld out product after this state clamping and there will be nozzle position out-of-size scope, time serious, there will be the situation of waste product.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of pipe end self clamping device, is solved the problem of existing Tool clamp structure, to improve mouth of pipe positioning precision and stability by two rod cylinder self-locking mechanism.
The technical solution adopted in the utility model is: a kind of pipe end self-locking clamping device, it is fixed on base plate by gripper shoe, it comprises handle, and one end chain connection of handle connecting pin and lower support is passed through in the bottom of described handle, and the other end of lower support is fixed on cylinder connecting plate; One end chain connection of the 4th connecting pin and upper support is passed through at the middle part of described handle, and the other end of upper support is connected with cylinder piston rod; Described cylinder piston rod is provided with contiguous block through the end of cylinder, and contiguous block is by the first connecting pin and connecting plate chain connection, and connecting plate passes through the second connecting pin and paw chain connection, described in be provided with compact heap paw rotate around the 3rd connecting pin; Described gripper shoe is provided with back-up block, and back-up block is provided with by the fixing fixed block of fixed block bolt, fixed block is provided with the limited block by bolt-locking, and described limited block matches with contiguous block, and described back-up block is fixed with positioning head.
The beneficial effects of the utility model are: this device is provided with two rod cylinder, and its one end is connected with handle, and the other end is provided with contiguous block.Hand propelled handle, drive contiguous block travels forward by cylinder piston rod, and because contiguous block and paw are coupled together by the first connecting pin and the second connecting pin by connecting plate, the 3rd connecting pin is fixing, and paw can rotate around the 3rd connecting pin.Cylinder piston rod travels forward and drives compact heap product piece to be clamped, and reaches self-locking when connecting plate is vertical state.The arrangement increases the precision and stability of mouth of pipe location, decrease percent defective.
