Novel rack processing device

Abstract

The invention discloses a novel rack processing device, which comprises a base, a slider, a rack processing device, a fixture seat, a pressure bar, a support bar, a dowel bar and an electromagnet. The top of the base is slidably connected to the slider, and the slider The rack processing device is provided at the end of the base, the fixture seat is provided on the side of the base, and the fixture seat and the rack processing device are located on the same side of the base, and the corresponding rack processing device is provided with a gap for placing the rack to be processed on the fixture seat. One end is fixed on the fixture seat, the other end is rotatably connected to the middle of the dowel bar, the pressure bar is fixed on the top of the dowel bar, and the end of the pressure bar corresponds to the notch, and the bottom end of the dowel bar is a free end, corresponding to the bottom end of the dowel bar An electromagnet is installed on the side of the fixture seat, and the dowel bar has ferromagnetism. The invention has the advantages of simple structure, reasonable design and simple operation, which is beneficial to reduce production cost and daily maintenance, is convenient to fix the rack to be processed, and is beneficial to improving processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a rack processing device for processing racks. Background technique [0002] The racks in the prior art are generally divided into straight toothed racks and helical toothed racks, which are paired with straight toothed cylindrical gears and helical toothed cylindrical gears respectively; the tooth profile of the toothed rack is a straight line rather than an involute In other words, it is a plane), which is equivalent to a gear with an infinite radius of the indexing circle. [0003] Before the blank of the rack is processed, the blank needs to be rough-machined. After the initial processing is completed, the upper and lower surfaces of the workpiece are plane-milled. The teeth on the machine are qualified. If the machining of the upper and lower planes of the workpiece is unqualified, it is easy to "knife" during the process of gear hobbing or gear shaping.

Problems solved by technology

This fixing method has the disadvantage of low fixing efficiency. Every time a workpiece is processed, the pressure plate needs to be disassembled and installed once, which affects the processing efficiency.

[0005] As a general mechanical component, racks and gears are widely used in various transmission machinery equipment in industrial production. At present, most racks use milling cutters of different standards to directly grind the rack blanks. However, the existing technology The complex structure of processing equipment is not conducive to daily maintenance, and the cost is high
