Abstract
The utility model discloses a turbine fine turning tool with a balance device. The turbine fine turning tool with the balance device comprises a working table body (1), wherein a locating clamping device (2) is arranged in the central position of the working table body (1). The turbine fine turning tool with the balance device is characterized in that the cross section of the working table body (1) is circular-shaped, and a counter weight device (3) is arranged on the circumferential surface of the working table body (1). The turbine fine turning tool with the balance device effectively resolves the problem that a gear ring portion centrifugates in the rotating process of a tool fixture and thus influences machining precision of the turbine caused by the fact that the gear ring portion of the turbine penetrates out of a disk body in the machining process of the turbine. The turbine fine turning tool with the balance device has the advantages of being simple in structure, scientific and reasonable in design, low in manufacture cost, and convenient to promote and use.
Description
Technical field
The utility model relates to the turbine technical field of processing equipment, is specifically related to the turbine finish turning frock with bascule.
Background technology
Turbine is the rotary power machinery that a kind of power conversion with flow working medium is mechanical energy, be widely used in aero-engine, gas turbine, the fields such as steam turbine, turbine is in the finish turning process, usually it need to be passed through the anchor clamps clamping on Lathe bench, at present, lathe adopts traditional frock clamp to carry out the finish turning of turbine usually in the turbine fine finishining process, but in the finish turning process, because turbine comprises disk body part and gear ring part, and the gear ring part protrudes from the disk body part usually, thereby cause frock in rotary course, the gear ring part can produce certain centrifugal force, thereby has affected the machining accuracy in the turbine process.
Summary of the invention
The technical problems to be solved in the utility model provides the turbine finish turning frock with bascule, this technical scheme efficiently solves turbine in process, because the turbine gear ring partly protrudes from outside the disk body, frock clamp is in rotary course, gear ring partly produces centrifugal, thereby affects the problem of turbine machining accuracy.
The utility model is achieved through the following technical solutions:
Turbine finish turning frock with bascule, comprise workbench body (1), the center of workbench body (1) is provided with positioning clamping device (2), it is characterized in that: described workbench body (1) cross section is provided with counter weight device (3) for circular on the periphery of workbench body (1).
The further Technological improvement plan of the utility model is:
Described counter weight device (3) is comprised of a plurality of arched weight pieces (31), and arched weight piece (31) is fixedly connected with workbench body (1) by securing member (4).
The further Technological improvement plan of the utility model is:
The shape of described arched weight piece (31), weight all partly are complementary with the turbine gear ring.
The utility model compared with prior art, have following obvious advantage: the utility model has increased counter weight device on the basis of conventional turbine processing tool, so that turbine cartridge is clipped in when rotating on the frock clamp, increased dynamic balancing, obviously improved the precision of turbine in the finish turning process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises workbench body 1, the center of workbench body 1 is provided with positioning clamping device 2, workbench body 1 cross section is circular, be provided with counter weight device 3 on the periphery of workbench body 1, counter weight device 3 has increased the dynamic balancing of turbine frock in rotary course, counter weight device 3 is comprised of a plurality of arched weight pieces 31, arched weight piece 31 is fixedly connected with workbench body 1 by securing member 4, and the shape of arched weight piece 31, weight all partly are complementary with the turbine gear ring.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
Claims (3)
1. with the turbine finish turning frock of bascule, comprise workbench body (1), the center of workbench body (1) is provided with positioning clamping device (2), it is characterized in that: described workbench body (1) cross section is provided with counter weight device (3) for circular on the periphery of workbench body (1).
2. the turbine finish turning frock with bascule according to claim 1, it is characterized in that: described counter weight device (3) is comprised of a plurality of arched weight pieces (31), and arched weight piece (31) is fixedly connected with workbench body (1) by securing member (4).
