Description

Socket steel ring clamping clip

Technical field

The utility model relates to steel ring welding positioning fields, and in particular to socket steel ring clamping clip.

Background technique

In heavy caliber pipe-jacking production, DRCP3500 circle jacking pipe structure sets clocking requirement among the double cushion rubbers of socket Only one of steel loop is arranged at the position Jiao Tai, but in welding production, this road steel loop is difficult to hold round (easily-deformable), and push pipe is caused to stop Jiao Tai Insufficient height, can not fixing seal cushion rubber, in turn result in push pipe joint sealing failure, do not meet design requirement.It is badly in need of setting thus The auxiliary tool for counting a kind of steel ring welding positioning, it is fixed to steel loop for clamping steel loop and socket punching block in welding steel loop process Position, enables steel loop to be close to socket punching block, it is ensured that production technology reaches design requirement.

Utility model content

The utility model for the technical problems in the prior art, provides socket steel ring clamping clip, can be in welding steel Steel loop and socket punching block are clamped in ring process, are positioned to steel loop, so that steel loop is close to socket punching block, it is ensured that production technology, which reaches, to be set Meter requires.

The technical solution that the utility model solves above-mentioned technical problem is as follows:

Socket steel ring clamping clip, the clamping tong arm being hinged including two, the clamping tong arm are set to same plane, Two clamping tong arms include that a handle for being divided into hinged place both sides and a gripping section, the decreased food are greater than The clamping segment length, which is characterized in that one of gripping section is long mouth end, another gripping section is short mouth end, described short The nearly long mouth extreme direction in mouthful end is equipped with a ball bumps, when the clamping clip realizes clamping function, the ball bumps with The long mouth end is cooperated by clamping element.

This socket steel ring clamping clip clamps steel loop and socket punching block in welding steel loop process, positions to steel loop, makes steel loop It can be close to socket punching block, solve the problems, such as that steel loop deforms when welding production, it is ensured that production technology reaches design requirement.

Based on the above technical solution, the utility model can also do following improvement.

Preferably, the long mouth end and the short mouth end are arranged in U-typed, and the U-typed cooperates socket punching block thickness.

Preferably, the ball bumps are located at the short mouth end end, and save material can avoid extra short mouth end simultaneously Interference between part and socket punching block.

Preferably, the long mouth end end end side Jin Duankou carries out chamfered, can reduce in the clamping clip use process Damage is scratched to socket punching block.

Preferably, the handle be in curved design, it is described it is curved meet ergonomics and adapt to manpower grasp shape, make With process is more labor-saving, use feeling is more preferable.

In attached drawing, parts list represented by the reference numerals are as follows:

1, handle, 2, long mouth end, 3, short mouth end, 4, connection pivot pin, 5, ball bumps, 6, chamfering, 7, socket punching block, 8, steel Ring, 9, the side A, 10, the side B.

Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

As shown in Fig. 1~2, socket steel ring clamping clip, including two be set to conplane clamping tong arm, two clampings Tong arm is hinged by connection pin shaft 4 and can flexibly relatively rotate within a certain angle, to guarantee that two clamping tong arms can flexibly be beaten It opens or clamps；Two clamping tong arms include the handle 1 and gripping section for being divided into hinged place both sides, according to lever principle, handle 1 Length is greater than clamping segment length, and one of gripping section is long mouth end 2, another gripping section is short mouth end 3, and short mouth end 3 is closely long Mouthful 1 direction of end is equipped with a ball bumps 5, when clamping clip realizes clamping function, ball bumps 5 and long mouth end 2 move toward one another, And cooperated by clamping element, long mouth end 2 is matched with short 3 inner shape of mouth end with 7 shape of socket punching block of required clamping.

In the present embodiment, the long mouth end 2 is arranged with the short mouth end 3 in U-typed, and the U-typed cooperates socket punching block 7 Thickness.

In the present embodiment, the ball bumps 5 are located at short 3 end of mouth end, and it is extra that saving material can avoid simultaneously Interference between short 3 part of mouth end and socket punching block 7.

In the present embodiment, closely short 3 side of mouth end in long 2 end of mouth end carries out chamfering 6 and handles, and can reduce the clamping clip and use Sharp parts scratch damage to socket punching block 7 in journey.

In the present embodiment, the handle 1 be in curved design, it is described it is curved meet ergonomics and adapt to manpower grasp shape Shape, makes that use process is more labor-saving, use feeling is more preferable.

In the present embodiment, because of the socket punching block 7 that production needs due to is arranged, the side A 9 and the long mouth of the utility model clamping clip 1 shape is held to cooperate, the B side 10 opposite with the side A 9 and short mouth end 3 cooperate, and the side B 10 is equipped with a groove, put in this groove The steel loop 8 that need to be positioned, steel loop 8 are vertically arranged with clamping clip, when the clamping clip is clamped movement, short mouth end 3 it is spherical convex It plays 5 and steel loop 8 is pressed into groove, and fit closely the two.

In the present embodiment, because production needs, socket steel ring clamping clip is made of 45# raw steel, and long 2 length of mouth end is 135mm, long 2 end chamfering 6 of mouth end are 90 °, and 6 radius of chamfering is 15mm, and short 3 length of mouth end is 87.5mm, short 3 end ball of mouth end 5 radius of shape protrusion is 10mm, and a length of 350mm of handle 1, link 4 diameter of pin shaft is 8mm, when clamping segment length mouthful end 2 and short mouth end 3 When being arranged in parallel, two 1, the handle shortest distances (1 thickness containing handle) are 110mm.

The utility model clamping clip is using steps are as follows:

1. wherein one section of pre- socket punching block 7 that is placed on of steel loop 8 is stopped the corresponding position Jiao Tai (i.e. groove) in advance when production；

2. in the clamping clip releasing orientation will clamping segment length mouthful end 2 towards the side socket punching block A 9, short mouth end 3 is in socket 10 groove of the side punching block B puts down pliers, and 5 position of short mouth end ball bumps alignment steel loop 8 is made to need clamped position；

3. handle 1 of holding with a firm grip presses to gripping section short 3 ball bumps of mouth end, 5 position in 7 groove of socket punching block steel loop 8, makes It is close to die wall；

4. 8 shape of steel loop is fixed with position after welder has welded anchor bar, when steel loop 8 no longer loosens, Release handle 1, lifts clamping clip；

Weld is needed to continue above procedure 5. changing under steel loop 8 one, until entire 8 firm welding of steel loop.

Using effect comparison:

Before the utility model clamping clip, after steel loop 8 welds, there is partial deformation, it is larger with 7 gap of socket punching block, it leads Cause height after stopping Jiao Tai molding relatively low；

It is substantially undeformed after steel loop 8 welds after the utility model clamping clip, it is fitted closely with socket punching block 7, only Height is qualified after Jiao Tai molding, meets design requirement.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
