Power tool rest used for driving and replacement of power tools

Abstract

The invention provides a power tool rest used for driving and replacement of power tools. The power tool rest is used for turning-milling composition machining and comprises multiple power tool holders arranged on the power tool rest. The power tools are installed in the multiple power tool holders. The power tool rest is characterized by further comprising a servo motor, a transmission shaft I, a transmission shaft II, a synchronous pulley I, a synchronous pulley II, a ball bearing I, a ball bearing II and a synchronous belt. According to the power tool rest used for driving and replacement of the power tools, power transfer from a power source of the power tool rest to the power tool holders is achieved through an adopted synchronous belt structure, and working noise of the power tools is effectively lowered; by the adoption of a guide disc structure and a way of conducting match grinding on an adjusting pad during assembling, smooth disengagement and engagement of linear keys at the ends of input shafts of the power tool holders and a linear key slot in the transmission shaft II during rotary tool replacement of a tool disc are guaranteed, and tool replacement of the power tool rest is achieved; and compared with a transmission structure, the structure is simple, and the mechanical failure rate is low.

Description

technical field [0001] The invention relates to the field of turning and milling compound processing, in particular to a power tool holder for driving and replacing a power tool. Background technique [0002] The manufacturing fields of aerospace, military industry and ship products have always been an important stage where advanced manufacturing technology plays a role. Turn-milling compound machining center has been widely used in these fields by virtue of its superior turning-milling compound An important part of a compound machining center, usually a number of powered tool holders are installed on the powered tool holder, and different types of powered tools are installed on each powered tool holder. Realize the milling process of different processes, so how to realize the power transmission from the power source of the power tool post to the power tool seat and the smooth tool change of the power tool post is the key to the performance of the power tool post.

[0002] The manufacturing fields of aerospace, military industry and ship products have always been an important stage where advanced manufacturing technology plays a role. Turn-milling compound machining center has been widely used in these fields by virtue of its superior turning-milling compound An important part of a compound machining center, usually a number of powered tool holders are installed on the powered tool holder, and different types of powered tools are installed on each powered tool holder. Realize the milling process of different processes, so how to realize the power transmission from the power source of the power tool post to the power tool seat and the smooth tool change of the power tool post is the key to the performance of the power tool post. At present, the power source of the power tool post to the The power transmission of the power tool holder and the tool change of the power tool holder are usually realized by the gear transmission structure and the hydraulic pressure clutch device. Through these structures, although the power transmission and the tool change of the power tool holder can be realized, the following problems will occur : 1) Due to the existence of gear transmission, the power tool is noisy when it is working; 2) The structure of the hydraulic clutch device is relatively complex, and the mechanical failure rate is high; 3) The hydraulic clutch device is affected by factors such as system hydraulic pressure when it is working, and its reliability is not high
