Clamp for machining planetary frame main body on horizontal machining center

Abstract

The invention discloses a clamp for machining a planetary frame main body on a horizontal machining center. The clamp is characterized by further comprising two fine adjusting mechanisms located at front end; in each fine adjusting mechanism, a base comprises a base body and a connecting part, the top of the base body is an oblique plane, the connecting part vertically extends upwards from one endof the base body, a transverse hole with the aperture slightly larger than the outer diameter of an adjusting screw rod is formed in the connecting part, a slide seat comprises a slide seat body anda matched oblique plane arranged at the bottom of the slide seat body, the top surface of the slide seat is a plane, one end of the adjusting screw rod is connected with one end of the slide seat body, the other end of the adjusting screw rod penetrates through the transverse through hole in the connecting part of the base and stretches outwards, two nuts are screwed to the adjusting screw rod andare located on two sides of the connecting part of the base, the matched oblique plane arranged at the bottom of the slide seat body presses the oblique plane of the base body, and the top surface ofthe slide seat body is level with an oblique positioning surface of a positioning plate and is coplanar with an oblique positioning surface at the rear end of the corresponding positioning plate; andthe base body of the base is fixed on the positioning surface of the corresponding positioning plate.

Description

technical field [0001] The invention relates to a machining fixture for a wind power gearbox, in particular to a fixture for machining a planet carrier main body on a horizontal machining center. Background technique [0002] The large-scale wind power gearbox adopts planetary transmission, which is a typical low-speed, heavy-load, variable torque and speed-up transmission. As an important part of the planetary transmission of a large-scale wind power gearbox, the main body of the planet carrier has a complex structure and bears the largest moment. Its quality directly affects the performance and life of the gearbox. The main body of the planetary carrier in a common large-scale wind power gearbox is as follows: figure 1 with figure 2 As shown, several axial planetary holes 101 are equally distributed around the center on the planetary carrier body 100, and several axial planetary holes 101 are distributed between two adjacent axial planetary holes 101 and located in the ...

AI Technical Summary

Problems solved by technology

The technical problems of this kind of fixture are: the front end face of the planetary carrier main body 100 needs many adjustment steps to meet the specified positioning accuracy requirements, the operation process is cumbersome, the adjustment time is long, and the processing cost is high, and the processing quality is unstable.

Therefore, the overall dimensional change range of the planetary carrier body 100 is limited within the thickness range of the thin metal sheet, and the adaptability is poor.
