Abstract
A non-machinability adjustment locating key for general assembly of a turbine partition board comprises a key main body, wherein two sides of the key main body are respectivley provided with two bolt holes, the two bolt holes on the same side of the key main body are distributed in the vertical direction and include an upper bolt hole and a lower bolt hole, each bolt hole is provided with a fastening bolt, and a plurality of washers are arranged between a nut of each fastening bolt and the key main body. The number of the washers between each fastening bolt and the key main body is adjusted, accordingly the relative position of the non-machinability adjustment locating key and a groove in outer steel and a partition board sleeve is adjusted so as to be smoothly matched with the groove in the outer steel and the partition board sleeve, cutting, welding and other complication operations are needless, match time of the adjustment locating key and the groove is effectively reduced, general assembly efficiency of the operating turbine partition board is improved, the adjustment process takes little time, and accordingly the turbine partition board can wait under a hoisted state.
Description
Technical field
The utility model relates to a kind of positioning key, and the non-processability that definite a kind of partition board of steam turbine general assembly of saying so is used is adjusted positioning key.
Background technique
In the total process of assembling of partition board of steam turbine, to be that cambered surface is corresponding is connected for outer steel and diaphragm housing ring, mobile mutually in order to prevent between outer steel and the diaphragm housing ring, generally is to offer groove respectively on steel and the diaphragm housing ring outside, placement positioning key in groove, thus moving between outer steel and the diaphragm housing ring avoided.Existing positioning key is integrated, when deviation appears in the groove location of offering on groove of offering on the outer steel and the diaphragm housing ring, the part of the sidewall of positioning key need be pruned, the part of pruning is welded on an other side of positioning key, carry out general assembly again, finish if can not produce once, need directly influence the general assembly efficient of partition board of steam turbine through repeatedly cutting welding process; Because the time of secondary operations positioning key is longer, for guaranteeing safety, the back wait positioning key that generally partition board of steam turbine need be landed machines.
The model utility content
For addressing the above problem, the purpose of this utility model provides a kind of pump wear resistance simulated environment simulator stand.
The utility model for achieving the above object, be achieved through the following technical solutions: the non-processability that a kind of partition board of steam turbine general assembly is used is adjusted positioning key, comprise the key main body, two bolts hole are all offered in key main body both sides, two bolts hole of the same side are in the distribution up and down of key main body, be respectively upper bolt hole and following bolt hole, clamping bolt all is set on each bolt hole, between the nut of clamping bolt and the key main body several pads are set.
Be further to realize the purpose of this utility model, can also be by the following technical solutions: described two upper bolt holes communicate, and two following bolts hole communicate.On the described pad through hole is set, the screw rod of clamping bolt passes pad.U type groove is set on the described pad, and the screw rod of clamping bolt passes pad.The thickness of described pad is d, d=0.1-1.0mm.The width of described key main body 1 is D, D=30-150mm.
Advantage of the present utility model is: by the quantity of pad between clamping bolt on adjusting the utility model and the key main body, thereby adjust the relative position of the utility model and outer steel and diaphragm housing ring upper groove, can cooperate smoothly with the groove on outer steel and the diaphragm housing ring, need not to cut complex work such as welding, effectively reduce the time of adjusting positioning key and groove fit, increase work partition board of steam turbine general assembly efficient, this adjustment process is shorter, can wait at the lifting state at partition board of steam turbine.The utility model also has compactness simple for structure, advantage cheap for manufacturing cost and easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the sectional structure schematic representation along Figure 1A-A line; Fig. 3 is an another kind of structural representation of the present utility model; Fig. 4 is the sectional structure schematic representation along Fig. 3 B-B line.
Reference character: 7 times bolts hole of 1 connecting key 2 clamping bolts, 3 upper bolt hole 4 pads, 5 through hole 6U type grooves, 8 diaphragm housing rings, 9 outer steel 10 grooves.
Embodiment
The non-processability that a kind of partition board of steam turbine general assembly is used is adjusted positioning key, as shown in Figure 1, comprise key main body 1, two bolts hole are all offered in key main body 1 both sides, two bolts hole of the same side are in the distribution up and down of key main body 1, be respectively upper bolt hole 3 and following bolt hole 7, clamping bolt 2 all is set on each bolt hole, several pads 4 are set between the nut of clamping bolt 2 and the key main body 1.As shown in Figure 2, on the described pad 4 through hole 5 is set, the screw rod of clamping bolt 2 passes pad 4, during conciliation, clamping bolt 2 is unloaded, by again that pad 4 is good in arranged on both sides, clamping bolt 2 is passed the through hole 5 of pad 4, clamping bolt 2 is being cooperated with key main body 1.The thickness of described pad 4 is d, d=0.1-1.0mm, d=0.1mm, 0.2mm, 0.3mm, 0.5mm, 0.7mm and 1.0mm commonly used, the width of described key main body 1 is D, D=30-150mm uses the key main body and the pad of different sizes according to the width and the precision that needs to adjust of the groove of offering on outer steel 9 and the diaphragm housing ring 8 10.All offer groove 10 on outer steel 9 and the diaphragm housing ring 8, the utility model is placed in two grooves 10, quantity by pad 4 between clamping bolt 2 on adjusting the utility model and the key main body 1, thereby adjust the relative position of the utility model and outer steel 9 and diaphragm housing ring 8 upper grooves 10, can cooperate smoothly with the groove on outer steel 9 and the diaphragm housing ring 10, need not to cut complex work such as welding, effectively reduce the time of adjusting positioning key and groove fit, increase work partition board of steam turbine general assembly efficient.
For the ease of to processing of the present utility model, as shown in Figure 3, described two upper bolt holes 3 communicate, and two following bolts hole 7 communicate, and carry out cutting of internal thread by the side in key main body 1, can finish, and guarantee bolt hole at same horizontal position.
Change pad 4 for the ease of further accelerating, as shown in Figure 4, U type groove 6 is set on the described pad 4, the screw rod of clamping bolt 2 passes pad 4.Pad 4 can be unloaded after clamping bolt 2 is unscrewed, arrange the quantity of each position Upper gasket 4, again tightening clamping bolt 2.
The technical solution of the utility model is not restricted in the embodiment's described in the utility model scope.The utility model not technology contents of detailed description is known technology.
