Description

Jigs for steel pipe cutting

technical field

The utility model belongs to the technical field of steel pipe processing, in particular to a clamp for cutting steel pipes.

Background technique

Steel pipe processing is an area that is getting more and more attention in industrial processing, and its application is becoming more and more popular.

During the construction process, steel pipes are often cut on the construction site. Because of the limited tools on site, most workers use hand-held steel pipes to cut, which not only cuts flatness is not high, but also easily causes damage to the personal safety of workers.

Some existing positioning fixtures have poor applicability to steel pipes of different diameters when fixing the steel pipes.

Utility model content

Aiming at the technical problems in the prior art, the utility model provides a jig for steel pipe cutting.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A jig for steel pipe cutting, comprising a screw rod, a connecting plate, a block and a lock ring, the connecting plate is arranged at one end of the screw rod, and the block has a semicircular groove for matching with the outer diameter of the steel pipe. Cooperate to clamp the steel pipe, the side of the clamping block opposite to the clamping groove has a threaded hole to connect with the connecting plate through screws, the lock ring has internal threads, and the lock ring includes a first lock block and a second lock block , the first locking block and the second locking block are hinged at one end, and the first locking block and the second locking block are locked at the other end by a locking screw and a locking nut for fixing the screw rod.

Preferably, the first locking block and the second locking block are hinged by a pin.

Preferably, a turntable is provided at the end of the screw rod opposite to the connecting plate.

Preferably, a layer of rubber pad is laid in the card slot.

Preferably, the rubber pad is adhered to the inner wall of the slot.

Preferably, the screw rod is integrally formed with the connecting plate.

The fixture for steel pipe cutting of the utility model has the following beneficial effects: the utility model clamps the steel pipe through the block connected to the screw rod, and then fixes the screw rod to the bracket through the lock ring, and can be replaced with different radii as required. The clamping block of the clamping slot, the steel pipe is firmly fixed, and it is easy to use, and is suitable for steel pipes of various diameters.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, a fixture for steel pipe cutting includes a screw rod 1, a connecting plate 2, a block 3 and a lock ring 4, the connecting plate 2 is arranged at one end of the screw rod 1, and the connecting plate 2 and the wire The rod 1 is integrally formed, and the clamping block 3 has a semicircular clamping groove 31, which is used to cooperate with the outer diameter of the steel pipe to clamp the steel pipe. The opposite side of the clamping block 3 and the clamping groove 31 has a threaded hole, so as to connect with the screw 5 The plate 2 is connected, the lock ring 4 has an internal thread, the lock ring 4 includes a first lock block 41 and a second lock block 42, the first lock block 41 and the second lock block 42 are hinged at one end, the first lock block 41 and the second lock block The locking block 42 is locked at the other end by the locking screw 6 and the locking nut 7 for fixing the screw rod 1 .

In this embodiment, the first locking block 41 and the second locking block 42 are hinged through the pin shaft 10, and the structure is simple.

In this embodiment, a turntable 8 is provided at the end of the screw rod 1 opposite to the connecting plate 2 to facilitate pushing the screw rod 1 .

In this embodiment, a layer of rubber pad 9 is laid in the slot 31, and the rubber pad 9 is bonded to the inner wall of the slot 31. The rubber pad 9 can increase the friction when contacting the outer circumference of the steel pipe, so that the steel pipe The position remains unchanged.

The working principle of the fixture for steel pipe cutting in the utility model is: pass the screw mandrel 1 through the support (not shown in the figure), etc., so that the clamping groove 31 clamps the steel pipe, and then the screw mandrel 1 is fixed to the support by the lock ring 4 superior.

The above embodiments are only exemplary embodiments of the utility model, and are not used to limit the utility model, and the protection scope of the utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the utility model within the spirit and protection scope of the utility model, and such modifications or equivalent replacements should also be deemed to fall within the protection scope of the utility model.
