Spindle box structure with five-surface machining

Abstract

The invention discloses a spindle box structure with five-surface machining. The spindle box structure with five-surface machining comprises a spindle box and multiple spindles arranged on the spindlebox. The spindles include one central spindle and the four side face spindles. The central spindle is arranged on the bottom surface of the spindle box. The outer end of the central spindle extends out of the spindle box and is provided with a direct connection pneumatic booster cylinder, and the inner end of the central spindle is in motor connection with the central spindle in the spindle box through a coupling. The four side face spindles are arranged on the four side faces of the lower end of the spindle box respectively, the outer end of each side face spindle extends out of the spindlebox and is provided with a direct connection pneumatic booster cylinder, and the inner end of each side face spindle is connected with a motor assembly in the spindle box through a synchronous belt. According to the spindle box structure with five-surface machining, the five spindles are installed on the five surfaces of the spindle box respectively, the five surfaces of a workpiece can be machined after one time of clamping, each spindle is high in relative position accuracy, the spindles on the side faces have identical transmission systems and are independent from one another, maintenance and usage are convenient to carry out, the structural technology is good, the production cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a spindle box structure of a gantry machining center, in particular to a spindle box structure with five-sided machining. Background technique [0002] The machining center is a highly automated multifunctional CNC machine tool. With the development of the manufacturing industry, the demand for machining centers is increasing, and the scope of use is becoming wider and wider. The spindle box is an important part of the machining center. [0003] In the process of processing parts through existing machine tools, if several processing surfaces need to be processed on the part, it is generally necessary to reposition and clamp the part before processing, which will cause multiple clamping due to multiple processes Positioning errors are generated, which affects the machining accuracy of the parts. In order to solve the above problems, the utility model patent with the publication number CN 206717493 U disclo...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that in the structure of the spindle box of the existing gantry machining center, in one clamping, the rough machining rigidity is poor, the precision is low, the disassembly and assembly are difficult, and the use is inconvenient when multiple machining surfaces are simultaneously machined. The problem of low work efficiency
