Trolley device for automatic replacement of machine tool accessories

Abstract

The invention discloses a trolley device for automatic replacement of machine tool accessories. The trolley device comprises a guide rail which is fixed to a machine tool foundation, an accessory dismounting trolley, an accessory mounting trolley, as well as an exchange station and a parking lot which are respectively arranged on the guide rail, wherein the accessory dismounting trolley and the accessory mounting trolley are movably mounted on the guide rail; the parking lot is provided with a parking lot position detecting device, and the exchange station is provided with an exchange station position detecting device. When the accessories of a machine tool are required to be replaced, the accessory dismounting trolley is moved to the exchange station; after the position is detected by the exchange station position detecting device, an end cover of a main shaft box of the machine tool is demounted, and the accessories are placed on the accessory dismounting trolley, the accessory dismounting trolley is moved to the parking lot, and the position is detected by the parking lot position detecting device; the accessory mounting trolley is moved to the exchange station, and after the position is detected by the exchange station position detecting device, the accessories on the accessory mounting trolley are mounted on the machine tool, and the accessory mounting trolley is moved to the parking lot. After the position is detected by the parking lot position detecting device, the machine tool can be started to process workpieces.

Description

Technical field [0001] The invention relates to the field of machine tool accessories, and more particularly to a device for automatically replacing a trolley for machine tool accessories. Background technique [0002] With the development of industry and the continuous improvement of automation, CNC machine tools are equipped with special machine tools such as vertical milling heads, universal milling heads, elongated milling heads, and flat rotary disks in order to further expand the scope of processing and use of machine tools. In order to automatically replace these machine tool special accessories, the headstock is often used to place and fix the machine tool special accessories. Some problems were discovered after the head magazine was used in conjunction with the machine tool: the machining range of the machine tool was lost, and the X-direction stroke was occupied by more than 1 meter; the number of special accessories for the replacement of the machine tool was limited; ...

AI Technical Summary

Problems solved by technology

Some problems were found after the head magazine was used together with the machine tool: the machining range of the machine tool was greatly lost, and the X-direction stroke was occupied by more than 1 meter; the number of special accessories for the machine tool was limited; the long workpiece was limited by the interference of the head magazine when clamping; It is difficult to install and debug the special accessories of the machine tool; the manufacturing cost of the head library is high, etc.
