The utility model integrates the knife-change actuating device in the inner of the head portion body to save the outer space, gripping jaws of the knife-change actuating device is driven by a motor and a cam, at the same time of the action of the knife-change actuating device generates elevate and descend to catch reserve cutter, the actuating device can be used to drive the other cam to rotate synchronously. A compression bar can press a clamp of the main shaft at the proper time to loose cutter which needs to be changed, which enables the gripping jaws to proceed the actions of rotating catch and change knives synchronously, thereby the effects that the utility is easy in structure and can change knife quickly with low change efficiency can be achieved.

Description

The cutter shifting transmission mechanism of comprehensive machine

The utility model relates to a kind of cutter shifting transmission mechanism of comprehensive machine, especially refer to that a kind of use is on the comprehensive machine of automatic tool changer, the cutter shifting transmission mechanism that this processing machine head body external space structure is simplified, the action of its main shaft chuck pine cutter and jaw tool changing is driven by a motor synchronously, reaches the rapid changing knife effect.

Existing comprehensive machine cutter shifting transmission mechanism, usually the action that must carry out comprises: the tool changing tool is got in the get loose lifting and the revolution of cutter, a jaw of a main shaft chuck, also promptly the cutter that must will change of this main shaft chuck unclamps, allow jaw take off cutter again, in tool magazine, get a new cutter in addition and change, to realize the automatic tool changer function.

The transmission device of two actions of conventional art knowledge control is separately independently, also promptly make the main shaft chuck cutter that gets loose by the oil pressure control mode action of forging a knife respectively, take out cutter by control cutter pawls such as a motor of an other self-contained unit, cams from tool magazine again and change, both do not have the synchronous interaction relation; Because two devices move separately, the motor of therefore controlling the cutter pawl must utilize modes such as Electronic Control, makes the time that its running is moved to be had the wait of resting, cooperate main shaft chuck pine cutter, with smooth tool changing; Because of this motor must stop, waiting for the action of main shaft chuck again and again, thus existing tool changing action institute's consumption time between 3 seconds one 4 seconds, big and need will influence output in the processing of frequent tool changing at output.

Thereafter the relevant designed comprehensive machine tool changing device of industry, being about to forge a knife structure function that action and cutter pawl get cutter of oil pressure control forms and links, when making main shaft chuck get loose cutter to forge a knife in oil pressure control, the cutter pawl is got new cutter and is turned round preparation at tool magazine synchronously and exchanges for, shortening its tool change time thus is between 1 second one 1.5 seconds, and the output of its comprehensive machine is improved.This design mainly is to make oil pressure tool striking device and the run-in synchronism of cutter pawl tool changing device, therefore structural design is still established a cutter pawl and a linkage in addition for the head body outside at main shaft chuck, or establish a cutter pawl and a linkage in addition at the head body upside, therefore structure is more loaded down with trivial details, and the mode of forging a knife is still kept oil pressure control, the oil pressure assembly of its increase (comprising oil storage equipment, oil hydraulic cylinder, control valve etc.) will increase cost, and often leakage of oil is arranged and influence the situation of environment.

Main purpose of the present utility model is to provide a kind of cutter shifting transmission mechanism of comprehensive machine, and its tool change time is short, simple in structure.

The purpose of this utility model is achieved in that a kind of cutter shifting transmission mechanism of comprehensive machine, comprises a head body, a tool changing device and a main shaft device for loosing knife; Wherein: head body is the hollow, rectangular housing, and its internal vertical is provided with a main shaft chuck, and its axle body is provided with one and can borrows downforce to make the get loose device for loosing knife of cutter of end taper hole; Tool changing device comprises motor, transverse axis, bevel gear group, roller finger cam group, jaw axle and stirs connecting rod; Wherein: motor is located at head body, establish a cone pinion at the output axle head, in head body, be provided with the transverse axis and the large bevel gear that drive by cone pinion, the transverse axis axle body is provided with one and makes the directed rotating roller finger cam group of jaw axle constant speed, and the large bevel gear back side is provided with and drives the cam groove of stirring connecting rod that is hubbed in the head body; The main shaft device for loosing knife comprises a cam and a depression bar, and the curve shape of this cam matches with jaw axle rotation time; Depression bar is a Y shape, is pivoted one in the depression bar rear end for the runner that compresses the cam wheel face, and its two rod end inside, front side are established a boss post respectively; Cam is fixed in the transverse axis axle body, and the centre of depression bar is hubbed on the head body madial wall, and its nose circle projection is folded on the device for loosing knife of main shaft chuck axle body.

Described roller-dear cam set comprises a cam and a roller-dear, this cam is installed in the transverse axis axle body, roller-dear is fixed in the power transmission shaft axle body, power transmission shaft is perpendicular to be located in the head body, its upper shaft extends to outside the head body, and establish an external gear at axle head, this external gear jaw axle head external gear outer with extending to head body is meshed.

The described connecting rod of stirring is a rectangle stock, distolaterally thereafter is hubbed on the head body internal side wall by a pivot, and its shaft one side is provided with a projection that stretches in the cam groove of the large bevel gear back side, and its front end one side is provided with the projection that a contract is gone into the jaw axle in addition.

The lower end axle body of described jaw axle is installed a jaw and is turned round the axostylus axostyle of getting the tool changing tool, the perpendicular side that is located at power transmission shaft of this jaw axle, the axle body epimere is the axostylus axostyle of croze axle construction, establish one in addition at croze axle axle body and extend the tubular croze shell on head body top, establish an external gear that is meshed with the gear of power transmission shaft in croze shell upper end, the axle body chosen place of this jaw axle is installed with one in addition and goes into to drive the H shape ring set that stretches for stirring connecting rod front end projection contract

Because the utility model is integrated cutter shifting transmission mechanism in the head body of main shaft chuck, overall space is dwindled, this transmission device can be driven by a motor simultaneously, the generation main shaft chuck is forged a knife and the cutter pawl exchanges synchronization action for, forge a knife synchronously whereby and the cutter pawl exchanges for, it is surplus at 1 second to keep tool change time, can save oil pressure control part simultaneously, reaches the effect of simplified structure, rapid changing knife.
