Abstract

The invention discloses a turbine shaft grinding clamp, which comprises a center, a turbine shaft and a machine tool chuck, wherein three clamping jaws are arranged at the clamping end of the clamp; a thread is formed at the other end of the clamp; the three clamping jaws are slightly opened and have the shape of a horn; a limiting step is formed at the tail end of the horn; and a through hole is formed in the middle of the clamp. The clamp has a simple structure and is easy to implement, the outer diameter of the turbine shaft is clamped through the three clamping jaws of the clamp, the turbine shaft is screwed on the thread of the grinding clamp through a threaded structure and is clamped through a pneumatic chuck of a grinding machine, the grinding length of the clamp is guaranteed by fixedly clamping the outer diameter of the turbine shaft, the stiffness of the turbine shaft is improved, the impact of the clamp on the turbine shaft in the grinding process is reduced, and working efficiency and product quality are improved.

Description

The turbine wheel shaft clamp

Technical field

The present invention relates to a kind of anchor clamps, be 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 finished whole grinding process, but 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 causing distortion, ground effect is had a strong impact on, even produces waste product.

Summary of the invention

The invention provides a kind of turbine wheel shaft clamp, when solving inefficiency, grinding workpiece is impacted the problem of considerable influence product quality.

For achieving the above object, by the following technical solutions:

A kind of turbine wheel shaft clamp comprises top, turbine wheel shaft, machine chuck, and described clamp end has three claws, and the other end has screw thread.

As this further prioritization scheme, described 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 described anchor clamps.

The present invention is simple in structure, be easy to realize, three claws by anchor clamps are clamped the turbine wheel shaft external diameter, be tightened in by helicitic texture on the screw thread of fixture for grinding machine, and clamp by 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 present invention is described in further detail below.

Fig. 1 is that the present invention assembles the application schematic diagram;

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

As shown in Figures 1 to 3, provided a specific embodiment of the present invention, an end of turbine wheel shaft 2 adopts top 1 location on the grinding machine 6 among the figure, the other end is by anchor clamps 3 clamping turbine wheel shaft external diameters, guarantee grinding length, one end of anchor clamps 3 has three claws 7, three claws 7 open flare slightly, flared end has positioning step, three claws 7 block turbine wheel shaft 2 external diameters, screw thread 5 by anchor clamps is tightened on the screw thread of fixture for grinding machine then, and by the air spider 4 on the grinding machine 6 anchor clamps 3 and turbine wheel shaft 2 is clamped.

The present invention comes turbine wheel shaft 2 is carried out grinding by 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.

Claims

1. turbine wheel shaft clamp comprises top, turbine wheel shaft, machine chuck, it is characterized in that described clamp end has three claws, and the other end has screw thread.

2. a kind of turbine wheel shaft clamp according to claim 1 is characterized in that three claws open flare slightly, at the loudspeaker end limited step are arranged.

3. a kind of turbine wheel shaft clamp according to claim 1 is characterized in that, through hole is arranged in the middle of the described anchor clamps.
