Abstract

The utility model relates to a fixed type clamp in a plastic composite pipe sealing ring of a steel wire mesh, comprising a clamp main body. The clamp main body is a supporting plate provided with two-four radial moving grooves and corresponds to the moving grooves; one side of the clamp main body is provided with two-four sector-shaped clamping pieces; the diameter of the outer arc of the sector-shaped clamping piece is the same as the inner diameter of the sealing ring; the other side of the clamp main body is provided with a rotary disc with two-four sliding tracks; the rotary disc is provided with a rotary handle; and connecting screws penetrate through the sliding tracks on the rotary disc and the moving grooves on the clamp main body respectively in sequence and finally are connected and fixed together with the clamping pieces. In the fixed type clamp, the contact area of the sealing ring and the clamp is enlarged, the sealing ring can be firmly fixed on the clamp, so that the phenomenon that the sealing ring separates from the clamp is avoided, the working efficiency of the sealing procedure is improved, the condition that pipes are stocked in the sealing procedure is greatly improved, the progresses of all the procedures on a production line are also consistent, and the whole working efficiency is also improved.

Description

Steel wire mesh frame plastic composite tube material seal mouth ring internally-fixed anchor clamps

[technical field]:

The utility model relates to a kind of stationary fixture, and these class anchor clamps are mainly used in the fixing of seal mouth ring in steel wire mesh frame plastic (polyethylene) the composite pipe production process.

[background technology]:

In the production of steel wire mesh frame plastic (polyethylene) composite pipe, produce corrosion for fear of chain mark, need use seal mouth ring that the multiple tube end face is sealed at sealing process, seal mouth ring needs anchor clamps to fix in sealing process, so that utilize heating plate to dock to the seal mouth ring heating and with multiple tube.Existing anchor clamps are for fixed outward, the cylindrical that heads on seal mouth ring by six thimbles is fixed, fixed effect is relatively poor, particularly after the heating plate heating, because seal mouth ring and heating plate are fitted closely, when removing heating plate, seal mouth ring is stressed easily to come off from anchor clamps, reduced the operating efficiency of sealing process, caused tubing to overstock in this operation.

[utility model content]:

The utility model purpose is to solve steel wire mesh frame plastic (polyethylene) composite pipe to produce the problem that seal mouth ring is easy to come off in the sealing process from stationary fixture, a kind of steel wire mesh frame plastic composite tube material seal mouth ring internally-fixed anchor clamps are provided, thereby improve the operating efficiency of sealing process.

The steel wire mesh frame plastic composite tube material seal mouth ring internally-fixed anchor clamps that the utility model provides, comprise jig main body, jig main body is one and has two to four gripper shoes that move radially groove, corresponding with shifting chute, be provided with two to four fan-shaped holding pieces in jig main body one side, the external arc diameter of fan-shaped holding piece is identical with the internal diameter of seal mouth ring, the jig main body opposite side is the rotating disc that has two to four dragging tracks, rotary handle is installed on the rotating disc, it is far away that the distance in the described dragging track and the rotating disc center of circle becomes gradually, on the position of dragging track and the jig main body to move radially groove corresponding respectively, attachment screw pass successively respectively dragging track on the rotating disc and the shifting chute on the jig main body at last and holding piece be connected and fixed.

The groove that moves radially on the described jig main body is preferably three, and is corresponding with shifting chute, is provided with three fan-shaped holding pieces in jig main body one side, and the dragging track on the rotating disc is similarly three.

Advantage of the present utility model and good effect:

The utility model uses in steel wire mesh frame plastic (polyethylene) composite pipe is produced, increased the contact area of seal mouth ring and anchor clamps, can be firm seal mouth ring be fixed on the anchor clamps, the phenomenon of having avoided seal mouth ring from anchor clamps, to come off, improve the operating efficiency of sealing process, tubing is improved greatly in the situation that sealing process overstocks, make that each operation progress is consistent on the production line, also improved whole operating efficiency.

[specific embodiment]:

Embodiment 1

Fig. 1 is a structural representation of the present utility model, and Fig. 2-1, Fig. 2 the-the 2nd, the utility model left view and A-A face cutaway view.Fig. 3, Fig. 4, Fig. 5 are the schematic diagrames that the utility model splits each parts of back.The utility model comprises jig main body 1, jig main body 1 is one and has two to four circular base slabs that move radially groove 8, this example is preferably three shifting chutes, corresponding with shifting chute, one side of jig main body 1 is provided with three fan-shaped holding pieces 3, the external arc diameter of fan-shaped holding piece 3 is identical with the internal diameter of seal mouth ring 2, the opposite side of jig main body is the rotating disc 5 that has three dragging tracks 6, rotary handle 4 is installed on the rotating disc 5, and attachment screw 7 passes the last and holding piece 3 of dragging track 6 on the rotating disc 5 and the shifting chute on the jig main body 18 successively and is connected and fixed.

Dragging track 6 becomes far away gradually with the distance in rotating disc 5 centers of circle, rotate rotary handle 4 and make rotating disc 5 rotations that have dragging track 6, motion drive attachment screw 7 by dragging track 6 moves radially along the shifting chute 8 on jig main body 1 gripper shoe, drive fan-shaped holding piece 3 and on jig main body 1 gripper shoe, move, move by the fan-shaped holding piece 3 of rotation rotary handle 4 last controls and step up or loosen seal mouth ring 2.

The utility model specifically practices as Fig. 6 to shown in Figure 9, the end face of seal mouth ring 2 is fitted on the jig main body 1, make three fan-shaped holding pieces 3 be positioned at the annulus of seal mouth ring 2, rotate rotary handle 4 and make rotating disc 5 rotations, rotating disc 5 rotation makes attachment screw 7 move along dragging track 6 and drives fan-shaped holding piece 3 and move on jig main body 1, make circle applying in fan-shaped holding piece 3 external arc and the seal mouth ring 2, because of the external arc diameter of fan-shaped holding piece 3 identical with the internal diameter of seal mouth ring 2, anchor clamps can be fixed seal mouth ring 2 internally by fan-shaped holding piece 3, clamp, counter-rotation rotary handle 4 can unclamp seal mouth ring 2.
