When the steel claw is clamped, the steel claw is hung to a clamping station through a crane, the steel claw is clamped in a side-standing manner, the upper part and the lower part of the steel claw are respectively clamped through an upper clamp group and a lower clamp group, and in the clamping process, two nuts on a lead screw relatively move by rotating the lead screw to clamp the steel claw; the claw pole head of steel claw withstands the backup pad, and the setting up of backup pad cooperates anchor clamps group and lower anchor clamps group, prevents that the steel claw from deviating the condition of setting for the orbit appearing in welding process such as upsetting, influences the welding quality of product. One end of the screw rod is processed into a square head, and can be fastened and adjusted through a special socket wrench.

Preferably, 2-4 middle supporting laminated plates are additionally arranged between the upper clamp group and the lower clamp group, the middle supporting laminated plates are perpendicular to the supporting side plates and the supporting plates, vertical supporting rib plates are fixed between the middle supporting laminated plates, and the middle supporting laminated plates are fixedly connected with the supporting side plates on two sides through bolts. The middle supporting layer plate has a supporting function on a claw rod in the middle of the steel claw, has a load reducing function on the upper clamp group and the lower clamp group, and assists the upper clamp group and the lower clamp group to better finish clamping action on the steel claw.

Preferably, the top end of the supporting plate is additionally provided with a lifting lug. After the steel claw is clamped, the crane can move the steel claw and the steel claw clamp to the designated position of the friction welding machine together by hooking the lifting lug.

Preferably, the one side that two tong are relative be the arcwall face, the crooked radian and the steel claw phase-match of arcwall face make two tong can be better press from both sides the steel claw tightly.

Compared with the prior art, the utility model beneficial effect who has is:

the utility model has simple structure and reasonable design, is suitable for fixing the steel claw on the horizontal friction welding machine, and has simple and convenient use; and the middle supporting layer plate and the vertical supporting rib plate are arranged to support a claw rod in the middle of the steel claw, so that the load reduction effect is realized on the upper clamp group and the lower clamp group, and the upper clamp group and the lower clamp group are assisted to better finish the clamping action on the steel claw.

FIG. 2 is a schematic structural view (left side view) of the steel claw clamp;

fig. 3 is a schematic structural view (top view) of the steel claw clamp.

In the figure: 1. a support plate; 2. a fixing plate; 3. lifting lugs; 4. a lead screw; 5. a nut; 6. a middle support layer plate; 7. erecting a support rib plate; 8. an arc-shaped surface; 9. supporting the side plates; 10. clamping a hand; 11. and (4) a steel claw.

Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1-fig. 3, steel claw anchor clamps, including

backup pad

1, 1 both sides of backup pad are fixed with support curb plate 9 respectively, upper portion and lower part between two support curb plates 9 are equipped with anchor clamps group and lower anchor clamps group respectively, it all includes a lead screw 4 with anchor clamps group down to go up anchor clamps group, the screw thread opposite direction that sets up to both ends in the middle of the lead screw 4, be provided with two nuts 5 on the lead screw, two nuts 5 set up respectively in the position that screw thread opposite direction, and two nuts 5 are a tong 10 of fixedly connected with respectively, lead screw 4 both ends are fixed with two support curb plates 9 through fixed plate 2 respectively.

In this embodiment:

2-4 middle supporting laminates 6 are additionally arranged between the upper clamp group and the lower clamp group, the middle supporting laminates 6 are perpendicular to the supporting side plates 9 and the supporting plates 1, vertical supporting rib plates 7 are fixed between the middle supporting laminates 6, and the middle supporting laminates 6 are fixedly connected with the supporting side plates 9 on two sides through bolts.
