In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of 3D printing powder-scraping device with collision checking function, drives including actuator and by the actuator
Scraper a, which is characterized in that driving member is additionally provided between the actuator and scraper；The driving member passes through the first spring
It connect to form the first pars contractilis with actuator, the driving member connect to form the second pars contractilis with scraper by second spring；Institute
Stating the first pars contractilis further includes the first position limiting structure for limiting the first telescopic spring length；Second pars contractilis further includes
For limiting the second position limiting structure of second spring collapsing length；It is provided on the actuator for detecting actuator and passing
First displacement sensor of moving part distance, is provided with the second displacement for detecting scraper Yu driving member distance on the scraper
Sensor.
First position limiting structure includes upper locating piece and lower locating piece；The upper locating piece and lower locating piece position are opposite
It answers.
Second position limiting structure includes upper spring installation part and lower spring mount；The upper spring installation part is fixed on
On the scraper, the lower spring mount is fixed on the driver plate；The upper spring installation part has pacifies on a spring
Dress face, the lower spring mount have mounting surface under a spring, and the second spring is located at mounting surface and bullet on the spring
Under spring between mounting surface.

The displacement of the first detection plate is surveyed, the second displacement sensor is used to detect the displacement of the second detection plate.
The utility model 3D printing powder-scraping device is respectively arranged with a spring in the two sides of driver plate, and passes through the
One position limiting structure and the second position limiting structure guarantee that cutter hub only has the spring of side to be stretched when moving, and the spring of the other side
It will not continue to compress.
Compared with prior art, the utility model has the advantages that
(1) the utility model detects driving spring stress by displacement sensor and stretches change in displacement occurred.Work as knife
Body movement is there is no when collision, value detected by displacement sensor should be maintained at a lesser value, when scraping cutter hub and work
When part collides, pulling force suffered by driving spring increases, and displacement has greatly changed.Displacement sensor detects driving spring institute
The monitoring collided to scraper is realized in the displacement of generation.It is at low cost, high reliablity.
(2) the utility model real-time is high, can effectively protect cutter hub, greatly reduces the troublesome operation of cutter hub replacement, thus
Mitigate the work load of maintenance personnel.
