Abstract

The utility model discloses an apparatus for working pin and hole when changing turbine blade. The apparatus for working pins and holes when changing a turbine blade comprises a bed body, a lower rotator, a support bracket, a carriage and a rotating arm. The bed body and the lower rotator are connected with a positioning rabbet through a positioning bolt, and the lower rotator can rotate oppositely to the bed body. The lower part of the support bracket is provided with a dovetail groove and a bearing, and the support bracket can roll oppositely to the lower rotator. The upper end of the support bracket is provided with a rack shaft, the carriage and the rotating arm, the carriage can move linearly along the axial direction of the rack shaft, and the rotating arm can rotate through the support to the both ends of the support bracket of the carriage. The apparatus for working pins and holes when changing the turbine blade has the advantages of short processing time, strong correcting ability and stable quality, and the work efficiency can be increased by about 10 times.

Description

Equipment for working pin and hole when changing turbine blade

The utility model relates to a kind of machining equipment, particularly a kind of equipment that is used to change turbine blade time processing pin and hole,

Steam turbine generator in use, sometimes the blade and the pin that need to damage change, general at present employing ratchet wrench and screw thread feeding processing pin and pinhole are sometimes, when do not come out in the pin top, just pin is taken out with the method for boring, changing the shortcoming that new blade adopts this method is long processing time, the trimming hole ability.

The equipment in processing pin and hole when the purpose of this utility model provides a kind of replacing turbine blade that improves crudy, high efficiency.

The utility model is achieved in that it comprises lathe bed, turns down, support, planker and pivoted arm, it is characterized in that; Lathe bed with under be connected with positioning spigot by bolt between turning, under turn and can rotate relative to lathe bed, have dovetail groove and be provided with bearing in the bottom of support, support can relative under turn that doing rolls moves, upper end at support is provided with rack shaft, planker and pivoted arm, planker can along rack shaft axially do rectilinear motion, pivoted arm rotates in support two supportings by planker.

The utlity model has weak point process time, capability for correcting is strong, and stay-in-grade advantage can be increased work efficiency about 10 times.

Below in conjunction with accompanying drawing the utility model is further described,

Fig. 1 is a structural representation of processing the equipment in pin and hole when changing turbine blade,

Fig. 2 is the right view of Fig. 1,

Shown in Fig. 1-2, it comprises lathe bed 1, under turn 2, support 3, planker 5 and pivoted arm 6, lathe bed 1 with under turn and be connected with positioning spigot by bolt 7 between 2, during work, turn on bolt 7, under turn 2 relatively lathe bed 1 horizontally rotate, determine support 3 position in the horizontal direction, have dovetail groove 9 in the bottom of support 3 and be provided with bearing 10, support 3 along dovetail groove 9 relative under turn that doing rolls moves, determine the position of support 3 in vertical direction, the upper end of support 3 is provided with rack shaft 4, planker 5 and pivoted arm 6, and on rack shaft 4, be provided with two-sided clamp mechanism 11, planker 5 can drive pivoted arm 6 along rack shaft 4 axially do rectilinear motion, cutter 12 is installed in the axis hole 13 of pivoted arm 6 and can be along the axial stretching that changes hole 13.
