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 the support making the multidigit strong point, for the less important work in the middle of machine-building process.The main method of welding during current making support is: first welded on support mobile jib any direction by first support arm, then bevel protractor is adopted with first for benchmark, reliablely successively carry out welding second, be the reliable welding of benchmark the 3rd with second again, until the most all support arms have welded.Produce support by such method, welding sequence is comparatively loaded down with trivial details, and the labour intensity of operator is also comparatively large, and when producing in batches, production efficiency is comparatively low.
Operation conveniently when welding, usually can manufacture special welding positioning tool to position all parts, as Chinese patent Authorization Notice No.: CN200720076075.3, authorized announcement date on July 30th, 2008, disclose a kind of welding work pieces locating support, comprise at least two along the mutual pipe clamping at an angle of its trend by part, 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 is in mutual card at an angle by inside part angle, card is provided with magnetic absorption part by part and welding work pieces abutted surface.Mutual pipe clamping is angularly used for being hooked institute's weld-end fittings by part, it angularly will be arranged according to angle needed for weldment, is interconnected and the card be stabilized in together more realizes or location stable to the appropriateness of welding work pieces by magnetic absorption part be provided with thereon by part by bridge piece.But, because its each pipe clamping leans on the angle between part to be fixing, a kind of specific support correspondingly can only be produced.For multidigit strong point support, often need require according to actual design and constantly change quantity and the angle of support arm, therefore this frock is difficult to meet the necessary requirement that multidigit strong point support under actual conditions manufactures.
Summary of the invention
The present invention is that the production efficiency when welding of multidigit strong point support in prior art is low, the deficiency of location inconvenience in order to overcome, and provides that a kind of production efficiency is higher and location is convenient, adaptability good multidigit strong point 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, the angle limit support comprising annular and the rotating disk be positioned at below angle limit support, described angle limit support is provided with at least three at the adjustable locating piece of angle limit support upper angle, described rotating disk is provided with the thread groove around disk upper surface central distribution, and the lower surface of described locating piece is provided with the tooth matched with thread groove.Welding locating support of the prior art, for locate support support arm to be welded keeper between for being fixedly connected with, cannot carry out angular adjustment, 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 in 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 limit support.In addition, the lower surface of locating piece is provided with tooth, can with the thread groove of disk upper surface to adaptation, like this when rotating disk is when rotating, locating piece can move to angle limit carriage center under thread groove effect, such locating piece can also clamp the primary stem portion in multidigit strong point support to be welded while positioning support brace, completes location, ensure that the accurate positioning of support to primary stem portion.Rotate backward rotating disk after having welded, locating piece moves towards the direction away from angle limit carriage center, namely gets loose with primary stem portion, takes off support after conveniently welding being completed.
As preferably, described angle limit support is provided with some evenly distributed, locating holes that radial direction runs through angle limit support, described locating piece is provided with the locating slot matched with angle limit backing thickness away from the lateral surface of angle limit carriage center, connected by alignment pin between described angle limit support and locating piece, the length of described alignment pin is greater than the width of locating piece.Connected by alignment pin between locating piece and angle limit support, the location of locating piece is comparatively efficient and convenient, and the length of alignment pin is longer, and like this when dial rotation drives locating piece to move inward, alignment pin can also play guide effect.
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 block.Auxiliary positioning block can treat with locating piece the effect that welder's part plays supporting and location jointly, ensures that positioning stablity is with accurate.
As preferably, described guide plate is provided with the chute arranged along guide plate length direction, and the bottom surface of described auxiliary positioning block is provided with the projection matched with chute.Such auxiliary positioning block can move in the chute on guide plate, can adapt to the support arm of different length.
As preferably, described locating piece and auxiliary positioning block are respectively equipped with V-shaped groove, the locating piece on same described guide plate and coaxial, the contour layout of the V-shaped groove on auxiliary positioning block.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 of angle limit carriage center, the end face of described mobile jib locating convex block is provided with groove, is provided with roller in described groove, and the axis horizontal of described roller is arranged and is parallel to the end face of mobile jib locating convex block.Arrange mobile jib locating convex block, make locating piece leave gap towards between the inside top and mobile jib of angle limit carriage center, there is mistake with locating piece and weld in the support arm can avoided being positioned at when welding on locating piece, and facilitates welding slag to discharge.When needs only need mobile mobile jib when the axial diverse location of mobile jib carries out multiple welding, now roller rolls, but still fitting with mobile jib in its surface, therefore without the need to carrying out secondary location, improves production efficiency.
As preferably, the surface of described roller is provided with around the V-shaped annular groove of roller axis arranged, cross section.Such roller can adapt to the positioning requirements of the mobile jib of different size, also improves the contact with mobile jib, ensures accurate positioning.
Therefore, the present invention has following beneficial effect: the adjustable angle of (1) locating piece, and adaptability is higher; (2) locating piece can position mobile jib and support arm simultaneously, and position fixing process quick and precisely; (3), when same mobile jib carrying out multiple welding, only need one-time positioning, production efficiency is higher.
