Mill deltoid device

Abstract

A flat and square head milling device belongs to the technical field of milling machinery, and comprises a lathe body, a power transmission mechanism, a feed box shaft, a tail seat, a chuck, a main shaft seat of the chuck, and a dividing control mechanism, wherein the lathe body is provided with a feed box; a milling cutter box is mounted on the feed box; the power transmission mechanism corresponds to one end of the lathe body; the two ends of the feed box shaft are pivoted at the two ends of the lathe body in the length direction thereof, and are in transmission connection with the power transmission mechanism; the middle part of the feed box shaft is matched with the feed box; the tail seat is mounted on the lathe body; the main shaft seat of the chuck is mounted at the other end of the lathe body, and corresponds to the tail seat; the chuck is mounted at one end of the main shaft of the chuck; the middle part of the main shaft of the chuck is pivoted on the main shaft seat of the chuck; the other end of the main shaft of the chuck is extended onto the main shaft seat of the chuck and equipped with a hand wheel; and the dividing control mechanism comprises a dividing disk, a dividing disk locating frame and a locating key. The device has the advantages that the labor intensity of operators can be reduced, flat or square heads can be precisely milled at the ends of a roller or similar workpieces, and the whole structure is simple.

Description

technical field [0001] The invention belongs to the technical field of milling machines, and in particular relates to a square milling and flattening device, which is used for machining and installing planes or key grooves on necks of roller-type workpieces. Background technique [0002] The above-mentioned concept of milling and flattening refers to the milling of the necks of the two ends of the rolls used in the steel rolling industry for workpieces with large lengths and diameters, which are symmetrical to each other, that is, two square planes separated by 180° for installation. (flat head) or square planes distributed at 90° (square head). The existing technology usually uses a desktop milling machine to act as a milling flat head or a flat square or a keyway mill. However, the disadvantages of using a desktop milling machine are: after each plane is milled, the roll needs to be reinstalled. After the reinstallation, it is necessary to Re-adjustment, so the labor inte...

Problems solved by technology

The existing technology usually uses a desktop milling machine to act as a milling flat head or a flat square or a keyway milling. However, the disadvantage of using a desktop milling machine is: after each plane is milled, the roll needs to be reinstalled. Re-adjustment, so the labor intensity of the operator is high, especially because the adjustment accuracy is difficult to control, it is easy to affect the milling accuracy, and then affect the use effect of the roll in the future

Although the use of double-sided milling machines can reduce the frequency of reinstallation and adjustment, for example, there is no intermediate link of installation and adjustment for milling and flattening heads, and it can be done in one go, but there is still a reinstallation and adjustment for processing square heads. Therefore, it is still not enough to fully reduce the labor intensity of operators and to fully guarantee the processing quality; in addition, the price of double-sided milling machines is extremely expensive, which is not affordable for ordinary small and medium-sized enterprises
