Abstract

The utility model relates to technical equipment of a combined metal structural member. The three-dimensional sizes that the metal structure requires are regulated by a pair of positioning support frames 1, positioning longitudinal beams 4 arranged on the positioning support frames, a shifting transbeam 5 and a transition plate 6; a framework structure is formed by combining and welding scattering materials on the technical equipment. The technical equipment has the advantages of high universality, long service life, small dimensional error of the combined metal structural members, convenience for mounting, dismounting and interchanging among all members, simplification of assembly technology of the metal structural members and reduction of cost.

Description

A kind of technological equipment that makes up hardware

The utility model relates to the Equipment Technology of machinery manufacturing technology field, is specially the technological equipment of cold working industry combined metal frame frame member.

The hardware combined process unit that uses in the prior art, especially the large-scale hardware that joins and combine by the more piece parts, as tower crane, arm, tower cap, counter-jib, slewing tower etc., when installing, exchange or joining, all strict controlling dimension.Existing way is to use a large amount of scattered technological equipments, each joint is all finished group technology with a cover technological equipment separately, because it is too numerous and diverse that assembled tool uses, relative error will strengthen, the parts that combination is come out, very difficult when the assembling assembling, interchangeability is relatively poor, while is owing to the locating hole on the frock, pin are less demanding on selection and precision, cause the part dimension accumulation of error that is combined into, have to that the union end of each joint parts compile is gone up behind the code name mutually correspondence and install and use, bring very big difficulty for user's installation and use, keeping.Used in addition frock is too much, has strengthened manufacturing expense undoubtedly.

The purpose of this utility model provide at above-mentioned the deficiencies in the prior art just a kind of general, assembly precision is high, can make to be combined into hardware and to reach and exchange fully and the technological equipment of long service life.

The purpose of this utility model is achieved through the following technical solutions.

The utility model adopts 2 and places the locating support on the guide rail to make up hardware symmetrically, locating support is made up of underframe, location longeron, moving beam, rebound, roller, locking device, has locating hole on location longeron, moving beam, rebound.

The utility model location longeron is fixedly installed on the underframe, and two moving beams are installed on the longeron of location, and rebound is installed on the moving beam.

Two moving beams are determined its distance apart by the locating hole location on the longeron of location.

Each rebound is determined its distance apart by the location of the locating hole on the moving beam.

Because the utility model adopts the locating support of two symmetries to make up hardware, and locating support is installed on the guide rail and can moves automatically, thereby can determine the length of the hardware that makes up as requested arbitrarily; Owing to be installed on the location longeron on the locating support, all have a lot of locating holes on moving beam and the rebound, can regulate arbitrarily between two moving beams and be equipped with distance between the rebound, thereby when the combination hardware, just can be on request the width and the thickness of definite hardware arbitrarily; To the large-scale hardware that is spliced by more piece, each joint parts is all located welding assembly with same set of frock, and each joint parts that can guarantee to be combined into are the scale error minimum each other, be convenient to assembly and disassembly from now on, and the realization each several part can exchange fully.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is a front view of the present utility model;

Fig. 2 is that A of the present utility model is to view.

For guaranteeing the rigidity of equipment, angle steel with＜125 * 125 * 12 is combined into the square steel pipe of the equal face of 130mm and makes underframe 3, location longeron 4, moving beam 5 and rebound 6 adopt the thick common low alloy structural steel of 30mm to carry out milling processing, in locating

hole

9,10,11, be bumped into the cover that comes out through heat treatment and correct grinding with tool steel, to guarantee that the aperture is not worn, increase the service life.

At first, respectively on two locating supports 1, regulate distance between two moving beams 5 according to the width dimensions of the hardware that will make up, by locating hole 9, the 10 usefulness alignment pins on moving beam 5 and the location longeron 4 moving beam is fixed on the longeron of location, regulates distance between each rebound 6 according to the gauge of combination hardware again.By locating hole 10,11 usefulness alignment pins are fixed in rebound on the moving beam, rebound can be made various profiles according to the shape of combination hardware, every combination one hardware needs the rebound more than two at least, on guide rail 2, move two locating supports 1 then, after regulating distance between the two stands by the length dimension of combination hardware, with locking device 8 with the two stands positioning and locking on guide rail 2, the diffusing material that will be used for making up hardware is at last assembled between two locating supports and is welded and gets final product, all method assembling welding like this of each joint parts later on, guarantee that fully the scale error between each parts reaches minimum, improve the interchangeability of each parts, for as tower crane, the tower arm, the tower cap, counter-jib, large-scale hardware such as slewing tower, reduced the scale error that respectively saves between the combiner, be convenient to install, dismounting, and reach fully and to exchange, not needing to number again use as each tower joint of tower crane, can install arbitrarily.The utility model has significantly reduced frock quantity and expense thereof, has simplified technology, has improved the quality of assembly, and practical application in producing proves practicable.
