Perforated box machining device

Abstract

The invention discloses a perforated box machining device. The perforated box machining device is characterized by comprising a fixed chassis and a movable plate, wherein the movable plate is eccentrically arranged on the fixed chassis and is provided with a pressing plate device for fixing a gearbox; a positioning device which is used for fixing the movable plate during machining is arranged on the fixed chassis and comprises a positioning base and a clamping piece; the clamping piece is movably arranged on the positioning base; and a plurality of clamping notches which is connected with the clamping piece in a matched manner are formed in the periphery of the movable plate. A plurality of to-be-machined holes with different sizes in the gearbox can be machined by one-time clamping, inaccurate machining caused by positioning errors due to repeated clamping is overcome, operation of machining of the to-be-machined holes in the gearbox can be carried out on an operating board, waste of labor, materials and financial resources is greatly reduced, work efficiency is improved, the device conforms to mechanized production, and effects of high delivery efficiency, convenience, practicality, time saving and labor saving are achieved.

Description

technical field [0001] The invention relates to a processing mechanical equipment, in particular to the processing of a gear case. Background technique [0002] The gear box is often used in wind power generating sets, and it is an important mechanical component. The main function of the gear box is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it get corresponding speed. Usually the speed of the wind wheel is very low, far below the speed required by the generator for power generation, so it must be realized through the speed-up effect of the gear pair of the gear box, so the gear box is also called a speed-up box. The gear case includes a plurality of holes to be processed of different sizes, usually including a first processing hole, a second processing hole and a third processing hole. [0003] Traditionally, gear boxes require multiple worktables of different sizes to process. However, the traditional box turn...

Problems solved by technology

[0003] Traditionally, the gear box needs multiple worktables of different sizes to process the operation. However, the traditional box turning technology can only process one hole in the gear box to be processed. After the processing is completed, it needs to be moved to the next A program processes the second hole to be processed, which requires secondary positioning, and so on

This kind of processing will cause a certain scale of deviation, resulting in inaccurate processing, which is not only troublesome, but also greatly increases the workload of the operator, so this old model is neither scientific nor practical, which makes the overall production and processing line have production efficiency Low, low factory value, time-consuming and labor-intensive
