The specific embodiment

Embodiment, a kind of support ring assembly welding frock of squeeze rolls of twin-roll squeezer as shown in Figure 1, comprises circular drain pan 1 and the swelling device, the positioner that are arranged on the drain pan 1, positioner is provided with some groups, is evenly distributed on the periphery of swelling device; The gap that adjustable size is arranged between positioner and the swelling device.

As shown in Figure 1, described swelling device comprises main shaft 10, goes up the tensioner part, tensioner part, regulating sleeve 15, support set 7 and several are evenly distributed on the automatic tractor in the support set 7 down.

Support set 7 is fixed on the drain pan 1 by guide post 24; The bottom of guide post 24 is fixed on the drain pan 1, and the top is threaded on the support set 7.As can be seen from Figure 4, guide post 24 is provided with three.

The bottom of main shaft 10 is installed in the center of drain pan 1 by taper roll bearing 21, and the middle part flexibly connects by taper roll bearing 22 and support set 7.

Last tensioner part is located at the top of support set 7, is threaded in the top of main shaft 10; Last tensioner part comprises spiral cover 9 and last slide lid 6, and last spiral cover 9 is fixed on the center of slide lid 6 by bolt 8, is threaded with main shaft 10.

Following tensioner part is located at the below of support set 7, is threaded in the bottom of main shaft 10; Following tensioner part comprises screwed lid 20 and lower slider lid 19, and screwed lid 20 is fixed on lower slider by bolt 23 and covers 19 center, is threaded with main shaft 10.

Rotating spindle 10, main shaft 10 just drive goes up spiral cover 9 and screwed lid 20 is done reverse moving axially simultaneously, and the interior circle of last slide lid 6 and lower slider are covered distance between 19 the interior circle and contracted in will be accordingly or extend out.

Regulating sleeve 15 is enclosed within the periphery of tensioner part and following tensioner part, and regulating sleeve 15 covers 19 conical surfaces with last slide lid 6 in the last tensioner part with the lower slider in the following tensioner part and contacts.

As Fig. 1, shown in Figure 5, described automatic tractor comprises stud 14 and the spring 12 that is enclosed within on the stud 14; Stud 14 flexibly connects by axle sleeve 13 and support set 7, and its outer end passes support set 7, is threaded on the regulating sleeve 15, and the inner is provided with the back-up ring 27 and the nut 11 of shutoff spring 12.

As can be seen from Figure 4, regulating sleeve 15 is provided with positioning spigot 28, like this, when last tensioner part, the following outside tensioner of tensioner part, utilizes tapering and tapering relative motion principle, and regulating sleeve 15 also extends out thereupon; When last tensioner part, when the tensioner part inwardly shrinks down, regulating sleeve 15 inwardly shrinks under the draw of automatic tractor.

As Fig. 2, shown in Figure 3, described positioner comprises locating shaft 3, several location-plates 16 and several pressing plate 17 of string on locating shaft 3, and pressing plate 17 is located between adjacent two locating shafts 3, is movably arranged on the drain pan 1 by bolt 25.As can be seen from Figure 1, the two ends of locating shaft 3 all are threaded, and drain pan 1 is passed in the bottom, and fixing by nut 2, the upper end is provided with the compressing member that is used to compress location-plate, and compressing member comprises the nut 5 that is threaded in locating shaft 3 upper ends and is located at the location-plate of the superiors and the back-up ring 4 between the nut 5.

As can be seen from Figure 2, each location-plate be serially connected in closely contact between the end on the locating shaft 3, be provided with between the end away from locating shaft 3 and the highly corresponding gap of support ring 26.

Use the utility model as follows to the course of work that support ring carries out assembly welding:

At first, make the location-plate 16 of every group of positioner and pressing plate 17 be in relaxed state, and all depart from the operating position; Then, a support ring 26 is enclosed within regulating sleeve 15 peripheries, is placed on the drain pan 1; Then, pull all pressing plates 17, it is pressed on the support ring, and, as shown in Figure 2, make it press support ring with bolt 18 fixation clips 17; Next, the location-plate of pulling all bottoms is pressed on the support ring; After adjusting the position of bottom location-plate, place second support ring in the above; Pull the location-plate of last layer, they all are pressed on second support ring, adjusting the position of location-plate; Again next, repeat this action, be pressed on the support ring in the top up to the top one deck location-plate.Afterwards, turn the nut 5 of locating shaft 3 upper ends, location-plate 16 is compressed all support rings; Next, in support ring, evenly insert many assembly welding positioning strips.Rotating spindle 10, make spiral cover 9, screwed lid 20 drive respectively slide lid 6 interior circle, lower slider lid 19 interior circle downwards, move up.Because regulating sleeve 15 covers 19 conical surfaces and contacts with last slide lid 6, lower slider, utilize tapering and tapering relative motion principle, make regulating sleeve 15 outside tensioners, be subjected to the tensioner effect of regulating sleeve 15, the assembly welding positioning strip combines closely with support ring, and has guaranteed support ring group endoporus axiality.Under the tensioner state, each support ring is welded on the assembly welding positioning strip gets final product.After finishing assembly welding work to support ring, backward rotation main shaft 10, last spiral cover 9, screwed lid 20 drive the interior circle of slide lid 6 respectively, the interior circle of lower slider lid 19 makes progress, moves down, last slide lid 6 and lower slider lid 19 unclamp regulating sleeve 15, regulating sleeve 15 inwardly shrinks under the draw of automatic tractor automatically, so just can take out the support ring group of finishing assembly welding.
