Abstract
The utility model discloses a round tube welding location device, including a lock rod, a concentric locking collar and an elastic lock sleeve. The lock rod consists of a plurality of cone-shaped sections with the same direction. One end of the lock rod is matched with a lock nut. The other end is equipped with a circumferential convex edge. An external screw thread is arranged on the concentric locking collar. One end of the concentric locking collar is equipped with a releasing nut. The sections of the concentric locking collar relative to the cone-shaped sections on the lock rod are circumferentially equipped with at least three communicating grooves. Steel balls are arranged in the communicating grooves. The quantity of the elastic lock sleeves is equal to the quantity of the cone-shaped sections on the lock rod. The same directional ends of the elastic lock sleeves are axially fixed on the same sides of the communicating grooves on the concentric sleeve. The sections of the elastic lock sleeves relative to the communicating grooves are equipped with arches uplifting outward. The steel balls are respectively against the cone-shaped sections of the lock rod and the uplifting outward sections of the elastic lock sleeves. With the round tube welding location device adopted for welding two sections of round tubes, the location is precise, the docked pipelines are ensured to be concentric, the quality of the docked pipelines is improved, and the working efficiency is greatly improved. The utility model is applied to the end-to-end dock of the round tubes.
Description
Technical field
The utility model relates to a kind of positioner.Be that two sections circular pipes are the end-to-end pipe welded retainer that welds together usefulness specifically.
Background technology
At present, it all is artificial positioning mode that two sections circular pipes are the end-to-end method that welds together location usefulness, promptly welds after the pipeline outside adopts manual method that two sections pipes are fixed together again.Also can realize location, the butt joint of two sections pipes though adopt artificial localization method, but need many people to help just can finish positioning and fixing during welding, not only can't realize one man operation, artificial many, the inefficiency that needs, and be difficult to accurate location, can not guarantee the pipeline that docks with one heart, the feasible pipeline quality that docks is relatively poor.
The utility model content
Problem to be solved in the utility model provides a kind of pipe welded retainer.Use this pipe welded retainer that two sections pipes are positioned, can not only locate accurately, guarantee that the pipeline that docks is concentric, improve the pipeline quality of butt joint, and can increase work efficiency greatly.
For addressing the above problem, the utility model is taked following technical scheme:
Characteristics of the present utility model are to comprise check lock lever, and there is concentric locking collar the outside of check lock lever.There is screw thread the outside of concentric locking collar, its outer flexible lock sleeve, and the one end has the release nut.Said check lock lever is made of some conical sections in the same way, and the one end is that cylinder, the other end have circumferential chimb, is processed with external screw thread on its cylindrical end and is furnished with locking nut, and circumferential chimb diameter wherein is greater than the internal diameter of concentric locking collar.Conical section maximum diameter on the check lock lever equates with the internal diameter of concentric locking collar and the two is and is slidingly matched.And have three grooves at least on corresponding that section concentric locking collar of each conical section on the check lock lever, these three grooves are equidistant layout along the circumferencial direction of concentric locking collar; The quantity of elasticity lock sleeve equates that with conical section quantity on the check lock lever their end in the same way all is on the groove homonymy that is axially fixed on the concentric locking collar.Putting with corresponding that section elasticity locking of groove all has arc outwards to swell, and a steel ball is all arranged in each groove, the relative two sides of this steel ball respectively with check lock lever on the uplift sector of a corresponding conical section and an elasticity lock sleeve offset.
Take such scheme, have the following advantages:
Because the utility model is provided with concentric locking collar in the outside of check lock lever, the flexible lock sleeve in the outside of concentric locking collar.Said check lock lever is made of some conical sections in the same way.Conical section maximum diameter on the check lock lever equates with the internal diameter of concentric locking collar and the two is and is slidingly matched.And have three grooves at least on corresponding that section concentric locking collar of each conical section on the check lock lever, putting with corresponding that section elasticity locking of groove all has arc outwards to swell, a steel ball is all arranged in each groove, this steel ball all with check lock lever on the uplift sector of a corresponding conical section and an elasticity lock sleeve offset.The check lock lever that employing is made up of some conical sections in the same way utilizes the steel ball of different-diameter, is being realized location and fixing by weldering pipe inside.Thereby can utilize slew gear to realize the continuous revolution welding of pipe.Do not need other people to help just can finish positioning and fixing during welding, not only can realize the one man operation, need manually less, high efficiency, and the pipeline that can accurately locate, guarantee to demonstrate,prove butt joint with one heart, make the pipeline quality of butt joint improve greatly.
Description of drawings
Fig. 1 is a pipe welded retainer structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, pipe welded retainer of the present utility model contains check lock lever 3, concentric locking collar 1 and elasticity lock sleeve 6.Check lock lever 3 wherein by 4 in the same way conical section constitute, the one end is that cylinder, the other end have circumferential chimb 10, is processed with external screw thread on its cylindrical end and is furnished with locking nut 2.Said concentric locking collar 1 is enclosed within the outside of check lock lever 3, and its outside is processed with screw thread, and the one end is rotary with and discharges nut 4, and circular diameter equals the conical section maximum diameter on the check lock lever 3 in it, is slidingly matched so that can be between the conical section on itself and the check lock lever 3.The diameter of said circumferential chimb 10 is greater than the internal diameter of concentric locking collar 1, in case check lock lever 3 skids off from concentric locking collar 1.Be processed with three grooves 8 on corresponding that section concentric locking collar 1 of each conical section on the check lock lever 3, these three grooves are equidistant layout along the circumferencial direction of concentric locking collar 1.The quantity of elasticity lock sleeve 6 equates with conical section quantity on the check lock lever 3, all is processed with screw thread on the circle in their end in the same way, and they screw corresponding groove 8 upsides at concentric locking collar 1 by this screw thread respectively.Arc is outside to swell 7 with all being processed on groove 8 corresponding that section elasticity lock sleeves 6, a steel ball 9 all is installed in each groove 8, these steel balls 9 respectively with check lock lever 3 on a corresponding conical section and the arc of an elasticity lock sleeve 6 outwards protuberance 7 offset.That section external diameter that elasticity lock sleeve 6 is connected with concentric locking collar 1 is less than the internal diameter that is welded pipe 5, so that make this section elasticity lock sleeve 6 and 5 of soldered pipes form the gap.
When need are end-to-end when welding together with two sections by weldering pipes 5, as long as be enclosed within the outside of elasticity lock sleeve 6 by weldering pipes 5, and screw locking nut 2 with two sections, can make two sections to be axially aligned by weldering pipes 5, realizes two sections by weldering pipes 5 the location and fix.
