Abstract

The utility model relates to an interlocking structure of knife changing device, which is arranged between the knife changing mechanism and the knife loosing mechanism of the processing machine of the vertical synthesis center. A second cam arranged at one side of the machining shaft is rotated synchronously along with a first cam of the knife changing mechanism by the drive of chains and sprockets, in order that the second cam can drive simultaneously a knife loosing seat sleeved on the machining shaft to work when a knife clamping part of the knife changing arm driven by the knife changing mechanism is rotated to the lower position of the knife tool of the machining shaft. The knife beating shaft of the knife loosening mechanism is pressed by the knife loosening seat to release the clamp of the knife tool, thereby achieving the object of releasing synchronously the knife tool.

Description

The serial verb construction of tool changing device

Technical field

The utility model relates to the automatic tool changer of vertical integrating center processing machine, refer to especially a kind of at tool changing device cutter-removing mechanism and cutter-exchange mechanism between be provided with the serial verb construction of the tool changing device of serial verb construction.

Background technology

The tool changing device of general known vertical integrating center processing machine is by a cutter-exchange mechanism basically, in order to do the cutter exchange between cutter tower and the processing axle, an and cutter of going up clipping by cutter-removing mechanism cooperation release processing axle, when moving to below the cutter of processing axle with tool change arm at cutter-exchange mechanism, can cooperate the action under forging a knife axially, make its holder loosen the cutter of institute's clipping, to finish the action of tool changing.

Wherein, the cutter-exchange mechanism of commonly using mainly drives combined type gear hobbing cam rotation by motor, this combined type gear hobbing cam is provided with groove and gear hobbing, the center of its tool change arm then is installed with a rotating shaft, and be provided with a rocking arm of the interlock that is meshed with the groove of combined type gear hobbing cam, an and rotary column that is meshed with the gear hobbing of combined type gear hobbing cam, so that when combined type gear hobbing cam rotates, transmission by groove and rocking arm, make the upper and lower displacement of this tool change arm, and, make the tool change arm rotation by the transmission between gear hobbing and rotary column.

As for, to commonly use cutter-removing mechanism and then be by hydraulic cylinder or pneumatic cylinder and drive the action that the axle of forging a knife is made downward loose cutter, and sense after tool change arm arrives the location really by inductor, the side drives cutter-removing mechanism and moves; So, whole processing machine not only needs to possess the equipment that hydraulic system is arranged, and it also need be connected complicated pipeline road with the between centers of forging a knife, and the drive unit that makes the axle of forging a knife is tending towards complicated loaded down with trivial details, increase the difficulty of equipment cost and maintenance, and when running can't be immediately and the tool changing component synchronization move, and influence the operating efficiency of whole processing machine.

And for example, No. the 367906th, Taiwan patent announcement " the cutter conversion is with moving device ", this novel patent be provided with one can with the device for loosing knife of tool change arm synchronization action; Wherein the manner of execution of tool change arm is identical with the manner of execution that aforementioned combined type gear hobbing cam is driven, do not give unnecessary details in addition: it mainly is that periphery at combined type gear hobbing cam is provided with plane cam, drive a pine folder cutter by plane cam and make swinging arm, constitute the interlock of pine folder cutter swing arm and main tapping again by an interlock assembly, so that when combined type gear hobbing cam rotates, but the action of the pine of Synchronization Control main tapping folder cutter.

But, the tool changing of its whole linkage, withdrawing cutter, and the action of pine folder cutter, be the control that is subjected to gear hobbing, groove and the plane cam of same combined type gear hobbing cam, therefore, when the dimensional accuracy at one of them position has deviation or wearing and tearing slightly, will influence whole tool changing accuracy of action, and can't proofread.

Especially, the composition member complexity of interlock assembly, not only size, precision are difficult to control, and volume, activity space that all members are formed are too huge, do not meet the design requirement of processing machine.

Summary of the invention

Main purpose of the present utility model is to provide a kind of serial verb construction of tool changing device, and it is provided with serial verb construction between the cutter-removing mechanism of vertical integrating center processing machine tool changing device and cutter-exchange mechanism.

The serial verb construction of this kind tool changing device, it is sheathed one loose tool rest on the processing axle of processing machine, this pine tool rest ring set is in the outside of processing axle, and the top position of forging a knife in the processing axle wears a briquetting, side at the processing axle is provided with one second cam, second cam rotates synchronously through first cam of transmission component and cutter-exchange mechanism, one side of this processing axle is provided with first swing arm that contacts with second cam in addition, and above loose tool rest, be pivoted with second swing arm, other is provided with and makes first, one connecting rod of two swing arm interlocks can constitute one and can accurately cooperate cutter-exchange mechanism to carry out the serial verb construction of loose cutter action synchronously.

Because the utility model is provided with serial verb construction between cutter-removing mechanism and cutter-exchange mechanism, so can accurately cooperate cutter-exchange mechanism to carry out the action of loose cutter and clipping cutter synchronously, can satisfy simultaneously the demand of production technology, improve the accuracy and the precision of whole tool changing work, improve the operating efficiency of whole processing machine.
