, it is necessary to dismantle and erector's part carries out subsequent processing again again processing after sequence, machine tool, can be through when processing multiple operation
The position of workpiece is often needed replacing, it is more inconvenient to cause use.
The patent of applicant's first to file again, Patent No. CN201110372429.X, a kind of multi-cutter machining tool belong to
Field of mechanical technique.It is small, complicated and cannot carry out multiple working procedure processing that it solves the existing machining tool range of work
Problem.This multi-cutter machining tool includes the lathe bed laterally set, has guide rail on lathe bed, is mounted with and can be moved along it on guide rail
Planker, toolframe is fixed on planker, toolframe is equipped with several base of tools for clamping cutter, is additionally provided on toolframe
The actuator that the base of tool can be driven to rotate, all base of tools are coupled to each other by transmission mechanism and actuator and one of cutter
Seat is connected, this patent can disposably fill much knives tool, and toolframe can carry out X with cutter, Y-axis is moved, and workpiece can
Carry out the Z axis movement of vertical direction so that machining tool can carry out the workpiece of clamped one time the processing of multiple working procedure, reduce
More tool changing clamping frequency.
But follow-up in use, it has been found that above-mentioned patented product only cutter can be carried out by actuator around cutter
Axis rotates, and workpiece is processed, and workpiece is merely capable of moving in the vertical direction so that workpiece adds in progress periphery
Man-hour, which still needs to again remove workpiece, to be put into other lathes and is processed, and causes that machining accuracy decreases and process is more.

Specific embodiment
The embodiment for saving process lathe to the utility model multicutter referring to figs. 1 to Fig. 4 is described further.
A kind of multicutter saves process lathe, includes the headstock 3 of lathe bed 1, the toolframe 2 of arrangement of tool and placement workpiece,
The fixture 10 of clamping workpiece is provided on the headstock 3, the fixture 10 is connected with the driving mechanism of its rotation of driving, described
Second base of tool 15 of fixed nonrotational cutter and first base of tool 7 of several fixed rotary cutters, institute are provided on toolframe 2
It states and several nonrotational cutters is provided on second base of tool 15, positioning is provided between second base of tool 15 and toolframe 2
Rotating mechanism, several nonrotational cutters are the prior art along second base of tool, 15 rotation direction circle distribution, wherein rotary cutter
In can around the cutter that own axes are rotated, nonrotational cutter be fixed on certain position can not rotation cutter.
As shown in the figure, wherein positioning rotating mechanism is made of motor and speed reducer, motor is preferably stepper motor 14, subtracts
Fast machine is connected by axis and second base of tool 15, and the axis of preferred speed reducer and second base of tool 15 is arranged vertically, that is, is reached
Second base of tool 15 can drive several nonrotational cutters to horizontally rotate jointly, as shown in figure 4, it is specially in toolframe
2 top positions are used for fixed placement rotary cutter, and second base of tool 15 is arranged in by the lower position slot milling of toolframe 2
In this space, nonrotational cutter is provided with 6 in the present embodiment, as shown in Fig. 2, 6 nonrotational cutters are circumferentially evenly arranged,
Wherein 3 nonrotational cutters can make to need to be used non-towards workpiece one side by the action of stepper motor 14 and speed reducer
Rotary cutter forms certain angle with rotary cutter, and the processing of chamfering or surface annular groove etc. can be carried out to workpiece.
Headstock 3 is whole in portal frame " n " shape in the present embodiment, towards 2 one side of toolframe and backwards to knife on headstock 3
2 one side of tool frame is respectively provided with the Z axis slide rail 5 of vertical direction arrangement, and front slide 8 and tail skid 6 are set respectively on two groups of slides 5, preceding
Slide plate 8 is the slide plate close to 2 one side of toolframe, is worn on front slide 8 and tail skid 6 and penetrates rotation axis 13,13 both ends of rotation axis point
Front slide 8 and tail skid 6 are not pierced by, and rotation axis 13 is pierced by 8 one end of front slide as front end, and the other end is rear end, and fixture 10 is fixed
In the front end of rotation axis 13, one brake disc 9 is set in the rear end of rotation axis 13, caliper 12 is set on tail skid 6, this braking
Pincers 12 are controlled preferably through gas circuit or oil circuit, and the motor that connection driving rotation axis 13 rotates on tail skid 6, motor
Belt, chain, gear, direct axis company or other modes can be used between rotation axis 13, before being given in certain the present embodiment
The component specifically arranged on 8 tail skid 6 of slide plate, but in addition to fixture 10 is necessarily placed on front slide 8, brake disc 9, braking
Pincers 12 and motor may also be arranged on front slide 8, but whether the balance consideration of convenient and counterweight is preferred as above for space, installation
State description position;For fixture 10 is enabled to move up and down, the mode lifting motor 4 that the prior art can be used is connected with leading screw,
Leading screw is connected directly between on front slide 8, one can also be arranged in rotation axis 13 and is rotatablely connected with rotation axis 13 such as following structures
Sleeve, leading screw is connected on sleeve, this mode can ensure fixture 10 in lifting, and the both ends of rotation axis 13 can be kept as far as possible
Balance avoids one end stress larger and lifting is caused to hinder.
The present embodiment medial bed 1 is provided with the moving mechanism that headstock 3 is enable to be moved along X-axis and Y-axis, i.e. toolframe 2
Be fixed on to be fixed on lathe bed 1, wherein can make the moving mechanism that headstock 3 is moved along X-axis and Y-axis using the prior art i.e.
Can, it is no longer repeated in the present embodiment;Certainly fix headstock 3, and toolframe 2 can carry out X-axis and Y-axis is moved
It is dynamic also.
As shown in Figure 1, when to work pieces process, headstock 3 is made to be moved along Y-axis first, fixture 10 is removed into 2 institute of toolframe
In region, i.e. worker station can drop on 1 side of lathe bed without body to be probeed into 1 inside of lathe bed by clamping workpiece on fixture 10
Low worker's danger coefficient after the completion of clamping, is moved by tri- axis of XYZ, before workpiece is made to be moved to corresponding rotary cutter, by turning
Cutter carries out Drilling operation to workpiece, and caliper 12 is contradicted in brake disc 9 at this time, the rotation axis 13 for being connected fixture 10
It can not rotate, and entire rotation axis 13 is positioned simultaneously by front slide 8 and tail skid 6, ensures its balance;Completion of processing it
Afterwards, when need to carry out doing chamfering or annular groove processing to workpiece surface, pass through stepper motor 14 first and speed reducer drives the second cutter
Seat 15 rotates, and making needs some fixed cutting tool 11 to be used to turn to forms centainly with workpiece(It is required that)Angle, after then starting
Motor on slide plate 6, while take-off the brake pincers 12, make the motor on tail skid 6 that rotation axis 13 and fixture 10 be driven to be rotated,
Surface processing can be carried out to workpiece at this time, carry out individual surface without removing to be mounted on other lathes workpiece again and add
Work not only saves process, and can save clamped one time technique, the raising processing technology of high degree, improves production efficiency,
The movement of three axis ensures that workpiece can reach any position and be processed.
