Technical field
The present invention relates to the turbine manufacturing equipment, relate in particular to a kind of clamping device that is used for turbine foundry goods gate cutting machine.
Background technology
Frock clamp plays crucial effect in commercial production, it refers to be used in machining piece-holder or location are reached the instrument of certain technological requirement.In the manufacture process of turbine, generally be that the mold cavity with a plurality of turbine foundry goods is installed on the tree type running gate system, said tree type running gate system connects crucible, casts.Traditional installation way is to utilize the fork-shaped anchor clamps to clamp the front and back end of turbine foundry goods respectively, and manually the ahead turbine workpiece carries out the emery wheel cutting.But there is following shortcoming in this installation way:
(1) utilizes the installation way of front and back end to lack fastness and reliability, in cutting process, be easy to generate shaking phenomenon, cause the turbine foundry goods parameters mistake after being cut.
(2) mode of manual propelling causes that easily manipulation is improper when operating personnel's dynamics is grasped inequality, and generation will be with the situation of all the other turbines accidental injurys on the string turbine workpiece.
Summary of the invention
The applicant provides a kind of clamping device of turbine foundry goods gate cutting machine to above-mentioned defective of the prior art, and is stable to the clamping of turbine foundry goods, effectively improves the cutting efficiency of turbine foundry goods cast gate.
The technical scheme that the present invention adopted is following:
A kind of clamping device of turbine foundry goods gate cutting machine comprises base, and the two ends of said base are the mounting bracket plate respectively, affixed connecting plate between the two stands plate, and the bottom surface and the base of connecting plate are affixed; Cylinder is installed on connecting plate, and the piston rod of cylinder and taper type slide block are affixed; Three-jaw mechanism is slidingly connected on the taper type slide block; Said three-jaw mechanism comprises that the position is mutually 120 ° and three pawl arms being connected with the step pin of sidewall internal face respectively; Three pawl arms connect back-moving spring each other; First end of three pawl arms connects pulley respectively; Second end of three pawl arms passes step and the outside wall surface on the sidewall internal face, between second end of three pawl arms, is being provided with the anchor ring boss that turbine foundry goods wheel hub is installed on the outside wall surface of sidewall, and said boss has the installing hole that turbine foundry goods wheel hub is installed.
It is further characterized in that:
Said supporting plate is the trapezoid support plate.
Beneficial effect of the present invention is following:
Through the present invention when the clamping with the wheel face of turbine foundry goods as datum level, make the end face of this datum level and anchor ring boss fit because boss has the installing hole that turbine foundry goods wheel hub is installed, make the side face of this hole and turbine foundry goods wheel hub fit tightly; Utilize the installation way of face type positioning reference and three-jaw to reduce the shake and the vibrations of turbine workpiece in cutting process to greatest extent simultaneously, guaranteed the depth of parallelism at the smooth and turbine back side of cutting back turbine foundry goods end face, the depth of parallelism reaches 0.07mm.And clamping is solid and reliable, and cut surface is beated less than 0.15mm.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
To shown in Figure 5, the present invention includes base 1 like Fig. 1, the difference mounting bracket plate 4 in the upper surface two ends of base 1, supporting plate 4 is the trapezoid support plate.Through the affixed connecting plate 11 of pin, the bottom surface of connecting plate and base 1 are affixed through pin between the two stands plate 4, have guaranteed the fixing reliable of clamping device.Flange 3 is installed on connecting plate 11, and cylinder 2 is installed on the connecting plate 11 through flange 3, and the piston rod of cylinder 2 and taper type slide block 6 are affixed; Three-jaw mechanism is slidingly connected on taper type slide block 6; Said three-jaw mechanism comprises that the position is mutually 120 ° and three pawl arms 7 being connected with the step 8-1 pin of the internal face of sidewall 10 respectively; First end of three pawl arms 7 connects pulley respectively; Second end of three pawl arms 7 passes step 8-1 and the outside wall surface on sidewall 10 internal faces, between second end of three pawl arms 7, is being provided with the anchor ring boss 8 that turbine foundry goods wheel hub is installed on the outside wall surface of sidewall 10, and said boss 8 has the installing hole that turbine foundry goods wheel hub is installed; The external diameter of its aperture and turbine foundry goods wheel hub 13 is suitable, makes the side face of this hole and turbine foundry goods wheel hub 13 fit tightly.The datum clamp face of the end face applying turbine foundry goods of said boss 8; Three pawl arms 7 connect back-moving spring 9 each other.Three pawl arms 7 are equipped with circular protection case 12 with the periphery of taper type slide block 6, and an end of circular protection case 12 connects connecting plate 11, and the other end is connected with sidewall 10.
In the clamping process; Earlier turbine hub 13 is placed the installing hole of the turbine foundry goods wheel hub on the clamp mechanism sidewall 10; Piston rod through cylinder 2 promotes taper type slide block 6 forward then, and pulley that three pawl arm 7 one ends connect is slided backward along the conical surface of conical sliding block 6, and the stretching of passing through on the taper type slide block of three pawl arms 6 discharges maximum grasp; To catch the turbine casting body, this installation way of three-point fix principle that utilizes makes clamping solid and reliable.As shown in Figure 5, the wheel face 14 of turbine is a datum level, the datum level when this datum level is also assembled as intensifier component.The wheel face 14 of the end face applying turbine foundry goods of said anchor ring boss 8.Adopt above-mentioned unified datum level to drop to the error of bringing in processing and the assembling process minimum.Also reduce the shake and the vibrations of turbine workpiece in the cutting process with the wheel face 14 of turbine workpiece to greatest extent as positioning reference, the turbine end face that has guaranteed to cut out smooth and with the depth of parallelism (depth of parallelism reaches 0.07mm) at the turbine back side.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of basic structure of the present invention, the present invention can do any type of modification.
