Description

Multidigit strong point support fixed-position welding device
Technical field
The present invention relates to a kind of fixed-position welding device, especially relate to a kind of multidigit strong point support fixed-position welding device.
Background technology
In the middle of machine-building process, often need to make the support of the multidigit strong point, for the less important work in the middle of machine-building process.The main method of the welding while making support is at present: first first support arm welded on support mobile jib any direction, then adopt bevel protractor taking first as benchmark, reliablely successively weld second, again taking second as the 3rd of the reliable welding of benchmark, until the most all support arms have welded.Produce support by such method, welding sequence is comparatively loaded down with trivial details, and operator's labour intensity is also larger, and in the time producing in batches, production efficiency is comparatively low.
For convenient operation in the time welding, conventionally can manufacture special welding positioning tool positions all parts, as Chinese patent Granted publication number: CN200720076075.3, July 30 2008 Granted publication day, a kind of welding work pieces locating support is disclosed, comprise that at least two are leaned on part along the mutual pipe clamping at an angle of its trend, this card is used for buckle and stable institute tack welding fitting by part, described card is connected by bridge piece by part, bridge piece leans on part angle inner side in mutual card at an angle, card is provided with magnetic absorption part by part and welding work pieces abutted surface.The pipe clamping that is mutually angle is used for being hooked institute's weld-end fittings by part, it is angle and will arranges according to the required angle of weldment, is interconnected and is stabilized in card together and more realizes or location stable to the appropriateness of welding work pieces by the magnetic absorption part that is provided with thereon by part by bridge piece.But, because its each pipe clamping is fixing by the angle between part, can only correspondingly produce a kind of specific support.For multidigit strong point support, often need constantly to change according to actual design requirement quantity and the angle of support arm, therefore this frock is difficult to meet the necessary requirement that under actual conditions, multidigit strong point support is manufactured.
 
Summary of the invention
The present invention be for overcome in prior art multidigit strong point support production efficiency when the welding low, locate inconvenient deficiency, provide that a kind of production efficiency is higher and location is convenient, the good multidigit strong point of adaptability support fixed-position welding device.
 
To achieve these goals, the present invention is by the following technical solutions:
A kind of multidigit strong point support fixed-position welding device of the present invention, comprise annular angle limiting bracket and be positioned at the rotating disk of angle limiting bracket below, described angle limiting bracket is provided with at least three at the adjustable locating piece of angle limiting bracket upper angle, described rotating disk is provided with around the thread groove of disk upper surface central distribution, and the lower surface of described locating piece is provided with the tooth matching with thread groove.Welding locating support of the prior art, for locating between the keeper of bracket leg brace to be welded as being fixedly connected with, cannot carry out angle condition, and adaptability is poor, in position fixing process, also cannot clamp mobile jib, and locating effect is not good yet.And in the present invention, locating piece is for locating the support arm portion of multidigit strong point support to be welded, its quantity can require to select according to actual welding, and its quantity is more than or equal to three under normal circumstances, and can raise angle between whole locating piece at angle limiting bracket.In addition, the lower surface of locating piece is provided with tooth, can be with the thread groove of disk upper surface to adaptation, like this when rotating disk is in the time rotating, locating piece can move to angle limiting bracket center under thread groove effect, locating piece can also clamp the mobile jib part in multidigit strong point support to be welded in positioning support brace like this, and mobile jib part is completed to location, has ensured the accurate positioning of support.After having welded, rotate backward rotating disk, locating piece, towards moving away from the direction at angle limiting bracket center, gets loose with mobile jib part, after conveniently welding being completed, takes off support.
As preferably, described angle limiting bracket is provided with some evenly distributed, locating holes of radially running through angle limiting bracket, on described locating piece, be provided with away from the lateral surface at angle limiting bracket center the locating slot matching with angle limiting bracket thickness, between described angle limiting bracket and locating piece, connect by alignment pin, the length of described alignment pin is greater than the width of locating piece.Between locating piece and angle limiting bracket, connect by alignment pin, the location of locating piece is comparatively efficient and convenient, and the length of alignment pin is longer, and in the time that dial rotation drives locating piece to move inward, alignment pin can also play guide effect like this.
As preferably, the lower end edge of described locating piece horizontally outward extends to form guide plate, and described guide plate upper surface is provided with auxiliary positioning piece.Auxiliary positioning piece can be treated welder's part and play with locating piece the effect of supporting and location jointly, ensures positioning stablity and accurately.
As preferably, described guide plate is provided with the chute of arranging along guide plate length direction, and the bottom surface of described auxiliary positioning piece is provided with the projection matching with chute.Auxiliary positioning piece can move in the chute on guide plate like this, can adapt to the support arm of different length.
As preferably, on described locating piece and auxiliary positioning piece, be respectively equipped with V-shaped groove, coaxial, the contour layout of V-shaped groove on locating piece and auxiliary positioning piece on same described guide plate.The support arm that V-shaped groove can adapt to different size is set, there is higher applicability.
As preferably, described locating piece is provided with mobile jib locating convex block towards the inside bottom at angle limiting bracket center, the end face of described mobile jib locating convex block is provided with groove, in described groove, is provided with roller, and the end face of mobile jib locating convex block is arranged and be parallel to the axis horizontal of described roller.Mobile jib locating convex block is set, makes locating piece leave gap between the inside top at angle limiting bracket center and mobile jib, there is mistake weldering with locating piece in the support arm that can avoid being positioned on locating piece in the time of welding, and facilitates welding slag discharge.When need to be in the time that the axial diverse location of mobile jib carries out multiple welding only need to mobile mobile jib, now roller rolls, but its surface still with mobile jib laminating, therefore, without carrying out secondary location, improved production efficiency.
As preferably, the surface of described roller is provided with around roller axis arranged, the V-shaped annular groove of cross section.Roller can adapt to the positioning requirements of the mobile jib of different size like this, has also improved and the contacting of mobile jib, and ensures accurate positioning.
Therefore, the present invention has following beneficial effect: the angle of (1) locating piece is adjustable, and adaptability is higher; (2) locating piece can position mobile jib and support arm simultaneously, and position fixing process quick and precisely; (3) while carrying out multiple welding on same mobile jib, only need one-time positioning, production efficiency is higher.
