Problems solved by technology

[0004] Aiming at the defects and deficiencies of the existing servo-powered tool holders, the present invention provides a single-servo powered tool holder. The power tool holder mounting holes on the cutter head are arranged in the axial direction of the cutter head, and a single servo motor simultaneously drives the cutter head to index and The cutting action of the power tool solves the problem of the transmission mechanism design and power switching of the cutterhead indexing and power tool drive

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like figure 1 As shown, for a single servo power tool post, the servo motor 1 is connected to the power input shaft 3 of the tool post body through the torque limiter 2, and the transmission torque on the torque limiter 2 is measured through the proximity switch Is1 to see if it is overloaded; When the torque is less than the preset value, the torque limiter 2 rotates normally, and the proximity switch Is1 has no induction signal; when the torque is overloaded, that is, the torque is greater than the preset value, the internal structure of the torque limiter 2 slips, and the proximity switch Is1 generates an induction signal.

[0020] like figure 2 As shown, the slip gear clutch device includes power input shaft 3, input shaft cutterhead side gear G11, slip gear G6, power switching gear IG7, power switching gear IIG1, shift fork 4 and piston IL...

Abstract

The invention belongs to the field of a tool rest for a numerically-controlled machine tool, and in particular relates to a single-servo power tool rest. In the invention, a tool disk and a power tool are driven by the same servo motor, and the power switchover problem of the tool rest is solved by a sliding gear clutch, wherein, the servo motor is connected with a power input shaft through a moment limiter, the tool disk is transposed through secondary gear transmission, and the power tool is driven by tertiary gear transmission; and the working conditions of the clutch, a triple fluted discand the power tool are controlled by a hydraulic system. Compared with the common servo power tool rest, the single-servo power tool rest has the advantages of low cost, light weight, small volume and the like, and adds an overload protection function.

Description

technical field [0001] The invention belongs to the technical field of tool holders for numerically controlled machine tools, in particular to a single-servo power tool holder. Background technique [0002] With the development of industry, higher requirements are put forward for the performance of machine tools such as processing time and processing accuracy. Important functional components of milling and milling complex machining centers. Traditional CNC tool holders can only be equipped with turning tools or boring tools for the most basic turning functions. For turning centers or turning-milling machine tools that can perform turning, drilling, milling, etc., in addition to requiring tool holders to have indexing In addition to the function, the driving function of the live tool is also required. [0003] Dual servo powered tool post, the tool post indexing mechanism and the driven knife driving mechanism are driven by two servo motors respectively. The use of two ser...
