An automatic grinding machine for gear parts

Abstract

The invention relates to an automatic grinding machine for gear-like parts. The automatic grinding machine comprises a machine frame and a distribution control box. A workboard is arranged at the upper part of the machine frame. A clamping and rotating device matched with a product is arranged in the middle of the workboard. Grinding devices matched with the clamping and rotating device are arranged on two sides of the worktable. Each grinding device comprises a grinding seat arranged on the worktable. A grinding longitudinal feeding device and a longitudinal feeding seat, which are matched with each other, are arranged on each grinding seat. A grinding and lifting device is arranged on each longitudinal feeding seat. A grinding shaft mounting seat is arranged on each grinding and lifting device. A grinding shaft is mounted on each grinding shaft mounting seat. The outer side of each grinding shaft is matched with a grinding motor on the each longitudinal feeding seat by means of a transmission component. A grinding wheel which is matched with the product on the clamping rotating device is arranged on the inner side of each grinding shaft. The grinding wheels of the grinding devices on two sides are in the same vertical plane. Through two groups of grinding knives matched in position, the fact that the positions of an upper arc groove and a lower arc groove, formed through processing, are corresponding is ensured, and the processing efficiency and the processing precision are greatly improved.

Description

Technical field [0001] The invention relates to the field of processing equipment for special parts, in particular to an automatic grinding machine for gear-like parts. Background technique [0002] In the field of parts processing, sometimes it is necessary to process some non-standard special parts, such as Figure 7 The part shown includes a shaft with two gear-like disks sleeved on the shaft. The upper and lower surfaces of the disk are provided with arc-shaped tooth grooves. Most of the existing machining of such parts is similar to gears. The casting of the blank is carried out first, and then the treatments such as grinding and polishing are carried out. However, the structure of such parts is more complicated than that of gears. Therefore, a specific casting mold is required during the casting process, and the accuracy of the casting mold is relatively high. Therefore, Inferior products are often produced, and they need to be polished and polished at the same time, which i...

[0002] In the field of parts processing, sometimes it is necessary to process some non-standard special parts, such as Figure 7 The part shown includes a shaft on which two discs similar to gears are sleeved. Arc-shaped tooth grooves are opened on the upper and lower sides of the discs. Most of the existing parts are processed similar to gears. The rough casting is carried out first, and then grinding and polishing are carried out. However, the structure of this type of parts is more complicated than that of gears, so a specific casting mold is required in the casting process, and the precision of the casting mold is relatively high. Therefore, Defective products are often produced, and they need to be ground and polished at the same time, which is relatively difficult, time-consuming and labor-intensive, and the yield and processing accuracy are not high
