Background technique
The existing servomotor for the hydraulic generator unit, comprise gray iron, piston rod, piston, guide holder and the U-shaped flashboard locking device that plays fixation.Locking device generally is placed on guide holder, and its locking performance depends primarily on following several factor: the parallelism and the gap that 1. lock flashboard inwall and piston lever brake groove plane; 2. lock plane, flashboard front and back and the parallelism and the gap that lock cylinder plane, plane, piston lever brake groove front and back; 3. running orbit of the alignment error of locking device and clamping block etc.4. the parallelism of the alignment error of guide holder and U-shaped flashboard and gap.There is the problem of two aspects in the existing servomotor for the hydraulic generator unit: one side is manufactured, the assembly technology more complicated, once the gap of locking flashboard inwall perpendicularity, roughness and flashboard fitting surface and lock groove perpendicularity, parallelism etc. are larger in the resultant error of the aspects such as manufacture, assembling, will cause the dumb or bite of the upper and lower action of clamping block.On the other hand, the lock groove matched with U-shaped flashboard is to dig on the servomotor piston rod, grind, and the extruding force that the locking flashboard can bear is very limited, and the locking flashboard is easily destroyed.
Summary of the invention
The technical problem to be solved in the present invention is: for a kind of simple in structure, easy to assembly, guide vane servomotor that lock function is safe and reliable is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of guide vane servomotor, comprise front end housing, cylinder body, back cylinder cover, piston, piston rod, guide holder and push-and-pull joint, described cylinder body is fitted between front end housing and back cylinder cover, piston and piston rod are set in cylinder body, described guide holder is fixed on the front end housing outer end, described push-and-pull joint is fixed on piston rod end, described guide holder global formation, guide holder is set in outside piston rod, offer the groove passed through successively for piston rod in guide holder, the first groove and the second groove, the width of described the first groove is identical with the diameter of groove, the width of described the second groove is greater than the width of the first groove, the guide holder bilateral symmetry is provided with for pinning the locking device of piston rod, described locking device is corresponding with the position of the second groove.This guide holder global formation, simple in structure, easy to process, two locking devices can be set, the effect of locking is better, and guide holder does not need as before by being welded to form, can prevent that guide holder is because of the distortion that welding brings, make the locking performance of locking device more safe and reliable, improve the bearing capacity of locking device, not fragile, and reduced the installation difficulty of locking device.
Described locking device comprises that the lockplate be fixed on guide holder, the guide pin bushing be fixed on lockplate reach the locking lever through guide pin bushing, described locking lever is vertical with piston rod to be arranged, locking lever one end is connected with the oil hydraulic cylinder that can make locking lever flexible, the telescopic end of locking lever and piston rod clamping, easy installation and removal, the locking performance is good.
For the ease of assembly manipulation, described guide holder end offers locating slot, and the positioning step on described locating slot and front end housing is connected.
Described guide holder top and bottom offer respectively some screws, are convenient to guide holder and front end housing is fixed.
Described guide holder cross section is rectangular.
The invention has the beneficial effects as follows: the guide holder global formation of guide vane servomotor of the present invention, simple in structure, easy to process, the locking performance of locking device is more safe and reliable, improved the bearing capacity of locking device, not fragile, and reduced the installation difficulty of locking device, make the servomotor operation more steady.
