Abstract
The utility model relates to a core bar and mandrel butt-welding device which comprises a rack and is characterized by also comprising a bearing sleeve I, a bearing sleeve II, a bearing sleeve III, a bearing sleeve IV, a triangular chuck I, a triangular chuck II, a connecting sleeve I and a connecting sleeve II, wherein the connecting sleeve I is sheathed in the bearing sleeve I and the bearing sleeve II, the connecting sleeve II is sheathed in the bearing sleeve II and the bearing sleeve III, the triangular chuck I is connected with the connecting sleeve I, the triangular chuck II is connected with the connecting sleeve II, and both the connecting sleeve I and the connecting sleeve II have hollow structures. By using the core bar and mandrel butt-welding device, the alignment accuracy is greatly improved after a mandrel is welded with a core bar, and the quality of the joint of the mandrel and the core bar after welding is improved, so that the probability of damaged inner surfaces of steel pipes rolled by a rolling mill is greatly reduced.
Description
Technical field
The utility model relates to a kind of welding and uses positioner, particularly core bar plug butt joint welder.
Background technology
Core bar in the bar milk adopts thread connecting mode with core bar that can not look like on the large-sized rolling mills being connected of plug and plug, and the mode that can only weld.Prior art is core bar and plug to be placed on the ground weld, but this mode of operation has following shortcoming: plug and core bar welding back centering are bad, and the surface of steel pipe is prone to go wrong when rolling; Plug and core bar need to rotate during welding, operation inconvenience; It is more to put ground welding core bar and plug junction burr, is difficult for polishing, and steel pipe internal-surface is prone to defective when making mill milling.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, and is easy to use, safe and reliable core bar plug butt joint welder.
The utility model addresses the above problem the technical scheme that is adopted: a kind of core bar plug butt joint welder; Comprise stand; It is characterized in that: also comprise a bearing holder (housing, cover), No. two bearing holder (housing, cover)s, No. three bearing holder (housing, cover)s, No. four bearing holder (housing, cover)s, a triangle chuck, No. two triangle chucks, an adapter sleeve and No. two adapter sleeves; A said bearing holder (housing, cover), No. two bearing holder (housing, cover)s, No. three bearing holder (housing, cover)s and No. four bearing holder (housing, cover)s are installed on the stand; A said adapter sleeve is sleeved in bearing holder (housing, cover) and No. two bearing holder (housing, cover)s, and said No. two adapter sleeves are sleeved in No. two bearing holder (housing, cover)s and No. three bearing holder (housing, cover)s, and a said triangle chuck links to each other with an adapter sleeve; Said No. two triangle chucks link to each other with No. two adapter sleeves, and a said adapter sleeve and No. two adapter sleeves are hollow structure.
As preferably, the axis of said adapter sleeve of the utility model and No. two adapter sleeves point-blank.
The utility model compared with prior art; Have the following advantages and effect: use the core bar plug butt joint welder in the utility model; The degree of accuracy of plug and core bar welding back centering has significant improvement; And improved the quality of welding back plug and core bar junction, thereby the probability that the steel pipe internal-surface that makes mill milling come out can throw into question significantly reduces.
Description of drawings
Fig. 1 is the structural representation of the core bar plug butt joint welder in the utility model.
Label declaration: 8, No. two adapter sleeves 9 of 7, numbers adapter sleeves of 6, No. two triangle chucks of 5, numbers triangle chucks of 4, No. four bearing holder (housing, cover)s of 3, No. three bearing holder (housing, cover)s of 2, No. two bearing holder (housing, cover)s of 1, number bearing holder (housing, cover) of stand, plug 10, core bar 11.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
As shown in Figure 1; Plug 10 in the present embodiment docks welder with core bar 11; Comprise stand 1, bearing holder (housing, cover) 2, No. two bearing holder (housing, cover)s 3, No. three bearing holder (housing, cover)s 4, No. four bearing holder (housing, cover)s 5, triangle chuck 6, No. two triangle chucks 7, an adapter sleeve 8 and No. two adapter sleeves 9; A said bearing holder (housing, cover) 2, No. two bearing holder (housing, cover)s 3, No. three bearing holder (housing, cover)s 4 and No. four bearing holder (housing, cover)s 5 are installed on the stand 1
Adapter sleeve 8 is sleeved in bearing holder (housing, cover) 2 and No. two bearing holder (housing, cover)s 3; No. two adapter sleeves 9 are sleeved in No. three bearing holder (housing, cover)s 4 and No. four bearing holder (housing, cover)s 5; No. one triangle chuck 6 links to each other with an adapter sleeve 8; No. two triangle chuck 7 links to each other with No. two adapter sleeves 9, and an adapter sleeve 8 and No. two adapter sleeves 9 are hollow structure.The axis of an adapter sleeve 8 and No. two adapter sleeves 9 point-blank.All be provided with fastener on triangle chuck 6 and No. two triangle chucks 7 and can block plug 10 or core bar 11.
When using, plug 10 is put into an adapter sleeve 8 and passed triangle chuck 6 No. one; Core bar 11 is put into No. two adapter sleeves 9 and passed triangle chuck 7 No. two.The position of adjustment plug 10 and core bar 11 makes the head of head and plug 10 of plug 10 be contacted with the point midway of No. two bearing holder (housing, cover)s 3 and No. three bearing holder (housing, cover)s 4, and a triangle chuck 6 and No. two triangle chucks 7 block plug 10 and core bar 11 respectively then.Use bonding machine that the contact site of plug 10 and core bar 11 is welded; Can rotate plug 10 in the welding process makes plug 10 and core bar 11 contacts site also rotate with core bar 11; Thereby make welding person can the position towards oneself be adjusted at the position of not welding, the carrying out of convenient welding.
Above content described in this specification only is to be illustrated what the utility model structure did.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
