Further, described clamp is flat rectangular body structure, and described clamp largest face has cross adjustment hole on the right side, and the right-hand member of described cross adjustment hole transverse direction is communicated with clamp right flank; Described clamp left surface upper end has U-shaped bayonet socket; Described bayonet socket snap in base plate and clamp side above bayonet socket near the vertical side of web; Described clamp is flexibly connected with the bolt hole on the moulding bed header board of workshop by the bolt through cross adjustment hole.
Further optimization, the upper-lower height of described bayonet socket is greater than base plate thickness.
Further, be placed with one between described clamp and the head of bolt and open round-meshed gripper shoe.
Further optimization, described circular hole external diameter equals the bar portion external diameter of bolt.
Further, the length in the bar portion of described bolt is greater than the thickness sum of gripper shoe, clamp, workshop moulding bed header board.
Beneficial effect of the present invention is as follows:
1. web bottom and base plate are fixed by the clamp of an adjustable position up and down by the present invention, ensure that in web bottom and base plate welding process, web plate and back plate can not move, and improves welding quality, decrease the probability of doing over again.
2. clamp of the present invention has cross adjustment hole, and utilize the bayonet socket had on the left of clamp that web is positioned at vertical position, utilize moving up and down of clamp that web bottom is fixed on appropriate location, fix overlapping the bolt hole having the gripper shoe of bolt to be close to clamp and workshop moulding bed again, web is made to be fixed on desired location, and can not offset in welding process, structure is simple, improves welding box body quality.
3. the upper-lower height of bayonet socket of the present invention is greater than base plate thickness, ensure that bayonet socket can snap in from bottom panel side smoothly.
4. in gripper shoe of the present invention, circular hole external diameter equals the bar portion external diameter of bolt, the bar portion of bolt can be inserted in this circular hole smoothly, increase this block gripper shoe, is to make the lifting surface area of clamp increase, and reduces pressure to the impact of clamp surface deformation degree.
5. the length in the bar portion of bolt of the present invention is greater than the thickness sum of gripper shoe, clamp, workshop moulding bed header board, ensure that bolt to pass after gripper shoe, clamp and workshop moulding bed by nut screwing clamping, is fixed by clamp.
