Reference：Base 1, support 2, spindle motor 3, chuck 4, workpiece 5, baffle plate 6, linear electric motors 7.
Specific embodiment
Content of the present utility model is illustrated below by embodiment：
Refer to Fig. 1, a kind of quick tool setting device based on linear electric motors position and resistance feedback, including base 1, base
1 side is provided with support 2, and attaching has chuck 4 on support 2, and chuck 4 is used for attaching workpiece 5；Or as needed can be in support 2
Upper setting spindle motor 3, the output shaft of spindle motor 3 is connected with chuck 4, by spindle motor 3 workpiece 5 can be driven to rotate, and fits
For various processing occasions；The opposite side of base 1 is provided with linear electric motors 7, and attaching has vertical arrangement on the mover of linear electric motors 7
Baffle plate 6, baffle plate 6 and chuck 4 and workpiece 5 thereon are corresponding；Also include compressive strain sensor and controller, compressive strain sensor
It is connected with baffle plate 6；Controller is connected with linear electric motors 7 and compressive strain sensor.
Among the present embodiment, the positioning precision of linear electric motors 7 is 0.1 μm, and linear electric motors 7 can be with the speed of 0.1~0.2m/s
Degree drives baffle plate 6 to be advanced to workpiece 5 and performs to knife, and linear electric motors 7 do the acceleration of retarded motion more than 10m/s2.Can be real
Now rapidly slow down.
Additionally, the resolution ratio of compressive strain sensor is for 0.1N or more preferably；Controller is single-chip microcomputer or PLC, preferably PLC.
Presetting cutter method using linear electric motors position of the present utility model and the quick tool setting device of resistance feedback includes：
1) it is 0.1~0.5N to set contact limitation scope in the controller；The contact limits the meaning of scope
Be, when baffle plate 6 by the pressure value for coming from workpiece 5 fall into the contact and limited scope when, it is believed that workpiece 5 and baffle plate
6 pairs of knife successes；
2) workpiece 5 is arranged on chuck 4, the zero point of workpiece 5 is towards baffle plate 6；Linear electric motors 7 drive baffle plate 6 with 0.2m/s
Speed to the zero point of workpiece 5 advance；
3) after workpiece 5 is contacted with baffle plate 6, signal of the compressive strain sensor by pressure value more than 0 passes to controller, controller
Regulation and control linear electric motors 7 slow down；
4) pressure value that compressive strain sensor real-time detection baffle plate 6 is subject to；Controller limits pressure value and contact
Scope is compared and is regulated and controled the motion of linear electric motors 7 with this；Specifically, when pressure value is more than 0.5N, controller is judged as surpassing
Zero crossing, it is 1 μm that controller regulation and control linear electric motors 7 retreat 10 steps, then repeats the comparing of pressure value and 0.5N, until pressure
Linear electric motors 7 stop retreating when force value is less than contact 0.5N；Then the comparing of pressure value and 0.1N is proceeded by, when pressure value is small
When 0.1N, it is judged as not arriving zero point, 1 step of advance of linear electric motors 7 is 0.1 μm, then repeats the ratio of pressure value and 0.1N
Compared with until linear electric motors 7 halt when pressure value is more than 0.1N, now pressure value is fallen into the range of contact limitation, is sentenced
It is disconnected successful to knife.
The above, only the utility model preferred embodiment, therefore can not according to this limit the utility model implementation
Scope, i.e., the equivalence changes made according to the utility model the scope of the claims and description and modification, all should still belong to this practicality new
In the range of type covers.
