Description

Welding method and welding system for lifting machine stand column
Technical Field
The invention relates to the technical field of machining of lifting machine stand columns, in particular to a welding method and a welding system for a lifting machine stand column.
Background
The double-column type lifter is a special mechanical lifting device commonly used by automobile repair and maintenance units, is a main type of lifter, and is widely applied to the maintenance of cars and other small-sized vehicles. The double-column type lifter has two types of symmetrical type and asymmetrical type. The arms of the four arms of the symmetrical lift are approximately equal in length so that the center (or center of mass) of the vehicle is at the center of the upright, which may be the best option for routine maintenance of pick-up and van type vehicles. The stand of machine of lifting is the main supporting component of machine of lifting promptly, and vertical sliding has the slip table that can follow vertical direction motion in the stand to can drive and connect each horizontal arm in the slip table and follow vertical direction motion, realize lifting of car.
A conventional lifting machine column 6, as shown in fig. 1, includes a base plate 61, two sides of the base plate 61 are respectively fixedly connected with a first connecting plate 62 perpendicular to the surface of the base plate 61, two sides of the first connecting plate 62 away from the base plate 61 are respectively fixedly connected with a second connecting plate 63 parallel to the surface of the base plate 61 in a direction toward away from each other, one side of the second connecting plate 63 away from the first connecting plate 62 is fixedly connected with a third connecting plate 64 parallel to the surface of the first connecting plate 62, one side of the third connecting plate 64 away from the second connecting plate 63 is further fixedly connected with a fourth connecting plate 65 parallel to the second connecting plate 63, the first connecting plate 62 and the base plate 61 cooperate to form a first groove 66, and the second connecting plate 63, the third connecting plate 64 and the fourth connecting plate 65 cooperate to form a second groove 67. At present, when the upright post 6 is processed, a steel plate is generally adopted directly, and then a bending machine is adopted to continuously bend the steel plate to form the upright post 6.
Firstly, the upright post is used as a main supporting part of a lifting machine, the structural strength of the upright post is required to be sufficient, the wall of the upright post is required to be thick in order to ensure the strength of the upright post, namely, the thickness of the selected steel plate is required to be thick, once the thickness of a plate is thick, the requirement on bending equipment is high, common bending equipment is difficult to meet, and the processing cost is obviously increased; second, because the stand structure is comparatively complicated, and the length of stand is longer, weight is great, therefore, when bending, the operation degree of difficulty is higher, and danger easily takes place, thirdly, because rather than the complex slip table in the stand, the main drive accepts the lifting of the horizontal arm of car, therefore the slip of slip table must be stable, and then, the size precision of stand must be higher, and the panel of adoption bends the fashioned stand, all need to get the size again when bending at every turn, and get the decline that the in-process very easily leads to size precision at the volume of size, finally lead to the quality decline of product.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows: the invention discloses a welding method of a lifting machine upright post, which comprises the following steps:
preparing materials, namely selecting a first channel steel and a second channel steel with different sizes as raw materials according to the sizes of a first groove and a second groove of a stand column to be processed;
step two, splicing and positioning, namely selecting two channel steels II to be respectively arranged at two sides of the outer end of the opening of the channel steel I, ensuring that the length directions of the channel steel I and the channel steel II are the same, enabling the openings of the two channel steels II to be oppositely arranged, and ensuring that one side wall of the outer end of the opening of the two channel steels II is respectively abutted against two outer side walls of the opening end of the channel steel I;
welding, namely welding the upper side and the lower side of a butt joint seam at the contact position of the first channel steel and the second channel steel along the length direction of the butt joint seam, and welding the upper side and the lower side of the butt joint seam along the two ends of the butt joint seam alternately towards the middle of the butt joint seam during welding;
and step four, detecting the strength, and after the first channel steel and the second channel steel are welded, detecting the strength of the welded joint to ensure the quality of the welded joint.
The implementation principle of the embodiment is as follows: adopt three channel-section steels to weld each other and form the stand, the shopping of channel-section steel is simple, reduce the fashioned link of bending of current stand, guarantee the wall thickness of stand, make the stand have sufficient structural strength, and avoided the stand size precision variation that leads to because of bending many times, only need weld one step process can realize the shaping of stand, in addition, because the stand is longer, adopt to weld along the middle part of the both ends of butt joint in turn trend butt joint, can reduce the stress that produces when welding through the alternate welded mode in both ends, and then reduce the dimensional error because of the welding produces, guarantee the quality of weld shaping back stand.
Example two: referring to fig. 2 and 3, a welding system of a lifter stand column comprises a base platform 1, a material carrying platform 2 is fixedly connected to one side of the upper portion of the base platform 1, the material carrying platform 2 is rectangular, the upper surface of the material carrying platform 2 is obliquely arranged, and two ends of the material carrying platform 2 extend upwards to form a first limiting plate 21. The bottom platform 1 is fixedly connected with a vertically arranged lifting cylinder 11 corresponding to the lower side position of the inclined surface of the material loading platform 2, a telescopic rod of the lifting cylinder 11 is upwards arranged and fixedly connected with a lifting plate 12 with the length direction being the same as that of the material loading platform 2, a material loading plate 13 is arranged on the upper side of the lifting plate 12, and the length direction of the material loading plate 13 is the same as that of the lifting plate 12.
Both sides of the upper surface of the lifting plate 12 extend upwards to form side plates 121, the upper sides of the two side plates 121 incline towards the direction away from each other, the lifting plate 12 descends to drive the material carrying plate 13 to descend, thereby make the curb plate 121 upside of lifting plate 12 and the downside parallel and level of carrying material platform 2, the one end of carrying material board 13 articulates in the one end of lifting plate 12, the other end downside of lifting plate 12 still vertical rigid coupling has telescopic cylinder 122, the telescopic link of telescopic cylinder 122 sets up upwards and can wear to establish overload flitch 13 lifting plate 12 and butt in carrying the flitch 13 downside, the one end that lifting plate 12 is close to telescopic cylinder 122 upwards extends and forms and decides the end plate 123, the inside wall of deciding the end plate 123 tends to the direction slope setting of keeping away from lifting plate 12, the other end of lifting plate 12 articulates has the end plate 124 of moving, the one end that lifting plate 12 is close to the end plate 124 of moving still articulates has two telescopic cylinders 125, the telescopic link of two telescopic cylinders 125 articulates in moving the end plate 124.
