Abstract
Provided is a turbine shaft grinding fixture, comprising a center, a turbine shaft and a machine-tool chuck. A clamping end of the fixture has three jaws, and the other end is provided with threads. The three jaws are slightly opened to form a horn shape. A limit step is provided at the end of the horn shape. The fixture has a through hole at the central portion. The turbine shaft grinding fixture of the utility model has a simple structure and is easy to realize. The external diameter of the turbine shaft is clamped by the three jaws of the fixture, and then the turbine shaft is screwed up on the threads of the grinding-machine fixture and is tightly clamped via the grinding-machine pneumatic chuck, with the grinding length being guaranteed by clamping and fixing the external diameter of the turbine shaft, thereby enhancing the rigid strength of the turbine shaft, reducing the impact on the turbine shaft during the grinding process and increasing the working efficiency and the product quality.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of turbine wheel shaft clamp.
Background technology
Because the required precision of turbine wheel shaft is higher, therefore to carry out grinding, normally adopt two thimble clamping methods to withstand the turbine wheel shaft two ends; Come the R face circular arc of grinding turbine wheel shaft, though this clamping method also can be accomplished whole grinding process, operating efficiency and crudy are all lower; And two thimble clamping methods radial impact to workpiece in the process that workpiece is processed is bigger; Tend to exceed the ability to bear of workpiece, make workpiece produce vibration, even cause distortion; Ground effect is had a strong impact on, even produces waste product.
The utility model content
The utility model provides a kind of turbine wheel shaft clamp, when solving inefficiency, grinding workpiece is impacted the problem of considerable influence product quality.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of turbine wheel shaft clamp comprises top, turbine wheel shaft, machine chuck, and said clamp end has three claws, and the other end has screw thread.
As this further prioritization scheme, said three claws open flare slightly, at the loudspeaker end limited step are arranged.
As prioritization scheme further, through hole is arranged in the middle of the said anchor clamps.
The utility model is simple in structure, is easy to realize, clamps the turbine wheel shaft external diameter through three claws of anchor clamps; Be tightened in through helicitic texture on the screw thread of fixture for grinding machine; And clamp through the air spider of grinding machine, utilize clamping turbine wheel shaft external diameter to guarantee its grinding length, improved the rigidity intensity of turbine wheel shaft; Reduce grinding process to the impact that turbine wheel shaft produces, improved operating efficiency and product quality.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is that sketch map is used in the utility model assembling;
Fig. 2 is part 3 structural representations (amplification) among Fig. 1;
Fig. 3 is the left view of Fig. 2.
Among the figure:
1, top; 2, turbine wheel shaft; 3, anchor clamps; 4, air spider; 5, screw thread; 6, grinding machine; 7, claw.
The specific embodiment
Shown in Fig. 1 to 3, provided a specific embodiment of the utility model, an end of turbine wheel shaft 2 adopts top 1 location on the grinding machine 6 among the figure; The other end is through anchor clamps 3 clamping turbine wheel shaft external diameters; Guarantee grinding length, an end of anchor clamps 3 has 7, three claws 7 of three claws to open flare slightly; Flared end has positioning step; Three claws 7 block turbine wheel shaft 2 external diameters, and the screw thread 5 through anchor clamps is tightened on the screw thread of fixture for grinding machine then, and through the air spider 4 on the grinding machine 6 anchor clamps 3 and turbine wheel shaft 2 are clamped.
The utility model comes turbine wheel shaft 2 is carried out grinding through the external diameter of clamping turbine wheel shaft 2, guarantees its grinding length, has avoided the process of cutting to the impact that turbine wheel shaft 2 produces, and has improved the rigidity intensity of turbine wheel shaft 2, has improved operating efficiency and product quality.
