Description
Technical field
The utility model relates to runner processing technical field of auxiliary equipment, especially relates to the manual positioner of a kind of small-sized cast welding runner.
Background technology
Runner is the core component of the hydraulic turbine, and its quality influence the normal operation of whole unit.Cast welding runner is that complex-shaped francis turbine runner is divided into several independent foundry goods, after machined again assembly welding integrally, runner is integrated primarily of crown, blade, lower ring assembly welding.Adopt the runner foundry goods of cast-weld construction little, shape is comparatively simple, easily ensures castability, is conducive to improving the accuracy of manufacture and reasonable employment material, reduces the requirement to casting ability simultaneously, shorten the manufacturing cycle.This structure can adopt different steel grades to different parts, as crown and lower ring adopt normal steel casting and blade adopts stainless steel, so both improves the anti-cavitation corrosion ability of runner, in turn saves the stainless steel material that price is relatively high.Therefore cast-weld construction runner is widely used in Francis turbine.Small-sized cast-weld construction runner because of compact conformation, blade openings is compared with little, welding limited space and welding job amount is large, welding quality requires higher, usually by positioner, need weld to reach ideal position.Conventional commercially available positioner build is comparatively large, cost is higher and keep in repair also more complicated.
Utility model content
The utility model overcomes shortcoming of the prior art, provide a kind of structure simple, easy to maintenance, with low cost and be easy to operate the manual positioner of small-sized cast welding runner.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The manual positioner of a kind of small-sized cast welding runner, it comprises base, be arranged at the support on base, bar portion rotates and is arranged at pedestal upper end and the fork rotated along vertical plane, rotated by bearing and be installed on fork upper end, along the supporting disk that fork axis rotates, be fixedly installed on the screw rod at supporting disk center straight up, screw the flange nut on screw rod, to be fixedly installed on fork and to be positioned on the downside of supporting disk for locking the clamp ring of supporting disk, to be arranged on base and to be positioned at the supporting seat of fork rotation direction side, rotate the worm gear be installed on supporting seat, be installed on and engage with worm gear with on supporting seat and one end arranges the worm screw of rotating disk, be fixedly installed in the rolling wheel of worm wheel shaft one end, connect the steel cable of rolling wheel and fork lower end, and the fixed pulley group be arranged at for steel cable guiding on base, the lower end of described supporting disk arranges the tight lock part stretching into clamp ring.
Preferably, described rotating disk is substituted by bar handle.
Preferably, described support is positioned at fork to rotate close side and be provided with buffer unit.
Preferably, described buffer unit is block rubber.
Preferably, described buffer unit is spring.
Compared with prior art, the utility model tool has the following advantages:
(1) the utility model is simple and convenient, safe and reliable and be easy to operation, it solves the weldering that causes because welding position is improper less than problems such as, not weld penetrations, thus improves runner weldquality.The utility model adopts rollover before and after supporting disk, rotatable version, can complete the welding displacement requirement of below 5T runner.
(2) manual positioner of the present utility model can be used for the workpiece welding various weld seam more complicated.In welding job, positioner distortion is very clear, and can overhaul manual positioner in time, renewal part cost is also lower.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the sectional view of A-A in Fig. 2, wherein illustrate only part-structure.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The manual positioner of small-sized cast welding runner shown in Fig. 1-3, it comprises base 1, be arranged at the support 2 on base 1, bar portion rotates and is arranged at support 2 upper end and the fork 3 rotated along vertical plane, rotated by bearing 4 and be installed on fork 3 upper end, along the supporting disk 5 that fork 3 axis rotates, be fixedly installed on the screw rod 6 at supporting disk 5 center straight up, screw the flange nut 7 on screw rod 6, to be fixedly installed on fork 3 and to be positioned on the downside of supporting disk 5 for locking the clamp ring 8 of supporting disk 5, to be arranged on base 1 and to be positioned at the supporting seat 10 of fork 3 rotation direction side, rotate the worm gear 12 be installed on supporting seat 10, be installed on and engage with worm gear 12 with on supporting seat 10 and one end arranges the worm screw 11 of rotating disk 13, be fixedly installed in the rolling wheel 14 of worm gear 12 rotating shaft one end, connect the steel cable 15 of rolling wheel 14 and fork 3 lower end, and the fixed pulley group 16 be arranged at for steel cable 15 guiding on base 1, the lower end of described supporting disk 5 arranges the tight lock part 9 stretching into clamp ring 8.
