Abstract

The utility model relates to a hydraulic welding rotator for welding main parts of a loader. The hydraulic welding rotator mainly comprises one frame and two pairs of columns. Each pair of columns comprises a driving column and a supporting column. A driving shaft on the driving column and a supporting shaft on the supporting column are controlled to be inserted into a spherical bearing on the side of a frame or withdrawn from the spherical bearing by a shaft changing cylinder and a piston rod. The rotation of the driving shaft is realized by a driving cylinder, the piston rod, a gear rack in the driving column and a gear arranged on the driving shaft. The hydraulic welding rotator has the advantages that the frame can rotate along an X and a Y coordinate axes and can be positioned in a stepless way; the obstacle surface of the operation of welders is small, which facilitates the welders to operate; simultaneously, the welding quality and the welding speed can also be relatively improved.

Description

Hydraulic welding die

The utility model relates to a kind of welding tooling equipment, particularly a kind ofly is used for welding the required water-gas welding of loading machine scraper bowl, swing arm, forebay and afer bay and switches through tire.

The loading machine that construction is used mainly contains scraper bowl, swing arm, forebay and afer bay four big parts and constitutes, the volume and the weight of these four big parts are all bigger, and top weld seam is many, direction is complicated, generally need upset repeatedly (forebay overturns nearly 8 times more than) in the ground welding, and each upset needs so not only to increase the task amount of crane greatly with the crane cooperation, and time-consuming, effort, influence production efficiency, to this, many manufacturers at present equal adapted welding positioner.Now the welding positioner that generally uses mainly contains two kinds, and a kind of is to be made of a framework and a rotating shaft; Another kind is made of two frameworks and two axes of coordinates.The former increases the difficulty of welding because the weld seam of weldment can not all forward horizontal level to, therefore not only is difficult to guarantee welding quality, and influences speed of welding; Latter welder's operating barrier face is big, makes welding job be difficult to carry out smoothly.Both common shortcomings are that support is huge, and framework can not be realized stepless location, thereby have the unhandy problem of welder.

In view of the foregoing, the purpose of this utility model provide a kind ofly save time, laborsaving and the obstacle face is little, tire is switched through in water-gas welding that make things convenient for the welder to operate.

The purpose of this utility model is achieved in that it comprises a framework and corresponding two pairs of pillars that are placed in about this framework with front and back, each is to comprising a driving pillar and a support column in the pillar, drive pillar and support column internal upper part and be provided with driving shaft bearing and supporting shaft bearing respectively, divide the driving shaft be located in driving shaft bearing and the supporting shaft bearing and its end of bolster to drive the piston rod that pillar and the support column outside changes in the shafting oil cylinder and be connected with being located at respectively, driving shaft links to each other with the spherical bearing that branch is located in the framework four side top chock respectively with the front end of bolster, drive the interior bottom of pillar and be provided with the driving oil cylinder, the upper end of this oil cylinder piston bar connects a tooth bar, and this tooth bar is meshed with gear on being located at driving shaft.When the need framework when the Building X parameter rotates, at first by pair of posts before and after the framework change the shafting oil cylinder and piston rod is released driving shaft and bolster from set up framework front and back spherical bearing separately, driving oil cylinder, piston rod and the rack drives gear drive axle that drives in the pillar by frame right rotates then, thus the Building X parameter rotation of implementation framework; When the need framework when the Building Y parameter rotates, then at first bolster and driving shaft are released from set up framework left and right sides spherical bearing separately by the shafting oil cylinder that changes of pair of right and left pillar, then by driving oil cylinder, piston rod and rack drives gear in the side drive pillar before the framework, driving shaft rotation, with the rotation of this implementation framework Building Y parameter.

The utility model has the advantages that: adopt a framework, two pairs of pillars to rotate and stepless location along X, Y two axes of coordinates by implementation framework, and driving mechanism places in the pillar, both can make the weld seam of weldment adjust to horizontal level, reduced the obstacle face of welder's operation again greatly, thereby bring great convenience for welder's operation, also improved speed of welding and weldquality simultaneously.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 drives pillar internal structure schematic diagram.

Fig. 4 is that the local K of Fig. 3 is to view.

Fig. 5 is the A-A view of Fig. 4.

Fig. 6 is a support column internal structure schematic diagram.

By accompanying drawing as can be known, the utility model is mainly by before a framework 4 and the framework 4 that is placed in, two driving pillars 1 on right side and a left side, two support columns 5 of rear side constitute, each drives pillar and each support column internal upper part is provided with driving shaft bearing 15 and supporting shaft bearing 19 respectively, driving shaft 17 is connected with the piston rod that changes in the shafting oil cylinder 2 respectively with the end of bolster 18, driving shaft 17 and the front end of bolster 18 link to each other with spherical bearing 13 in being located at framework avris top chock (internal gear) 9, are inserted in the spherical bearings 13 or from spherical bearing 13 by piston rod control driving shaft 17 that changes shafting oil cylinder 2 and bolster 18 and extract out.The tooth bar 10 that piston rod upper end in the driving pillar 1 in the driving oil cylinder 12 connects is meshed with the gear 18 on being located at driving shaft 17, this gear blocks with long keyway on the driving shaft 17 mutually by the flat key 16 on its endoporus that is connected, make it driving shaft 17 and both can rotate with gear 8, again can be parallel mobile at gear 8 endoporus.Move up and down by the piston rod control tooth bar 10 that drives oil cylinder 12, and driven gear 8 and driving shaft 17 rotations, with the rotation and the stepless location of this implementation framework 4.Sequence number 11 among the figure is a pedestal cap, and sequence number 7 is a guide pin bushing, the hydraulic pressure self-lock pin that sequence number 6 is used for the clamping weldment.
