Abstract
The invention belongs to the technical field of broaching machine, in particular relates to a protective device used for circular grating of numeric control deep hole broaching machine. The reading head mounting base of the protective device is taken as the mounting base plane of a reading head; the spindle is connected with a transition flange to output power; the guide screw can cause a seal cover not to damage a grating bar; the reading head mounting base, the spindle, the seal cover, an O-shaped seal ring and the transition flange form a sealed space, thus providing protection for the circular grating; the discharging hole and a closing plug discharge lubrication liquid permeated into the sealed space of the circular gratin; and the reading head and the grating bar form a circular grating detection mechanism, so as to provide a closed loop detection feedback signal. The protective device of the invention has low cost, good reliability and low maintenance cost.
Description
Technical field
The invention belongs to broaching machine device technique field, the round grating that is specifically related to a kind of numerical control deep-hole broaching machine is used protector.
Background technology
Running accuracy during numerical control deep-hole broaching machine deep hole processing needs high-precision measurement mechanism feedback signal to realize that closed-loop control guarantees.At present because the structural limitations of broaching machine itself needs the round grating and the high product of shell protection grade of big latus rectum to be difficult to import, the reality use be the round grating of no shell protection.The grating chi of circle grating must be taked special measure protection, in case otherwise the grating chi receives pollution will lose certainty of measurement.
Summary of the invention
For solving the problem of above-mentioned round grating protection, the present invention provides a kind of round grating of numerical control deep-hole broaching machine to use protector.
The round grating of numerical control deep-hole broaching machine of the present invention comprises with protector:
The casing that provides support for whole device;
The read head mount pad, the main shaft that are connected respectively with casing;
Read head is fixedly connected with the read head mount pad, and seal closure is fixedly connected with the read head mount pad;
On main shaft, be disposed with an O RunddichtringO, the 2nd O RunddichtringO, the 5th O RunddichtringO and counter flange, grating chi;
Counter flange is connected with main shaft through the O RunddichtringO, and counter flange is through also being connected with seal closure through the 3rd O RunddichtringO, the 4th O RunddichtringO;
Be used to discharge the outage and the sealing-plug of the liquid that infiltrates circle grating seal cavity.
The round grating of numerical control deep-hole broaching machine of the present invention has that cost is low, good reliability, is easy to characteristics such as maintenance with protector, and the present invention preferably resolves that the high big latus rectum product of present shell protection grade is difficult to import and the grating chi of circle grating must be taked the problem of special measure protection.

Read head 4 is fixedly connected with read head mount pad 2, and seal closure 6 is fixedly connected with read head mount pad 2;
On main shaft 3, be disposed with an O RunddichtringO 7, the 2nd O RunddichtringO 8, the 5th O RunddichtringO 14 and counter flange 12, grating chi 13;
Be used to discharge the outage and the sealing-plug 11 of the liquid that infiltrates circle grating seal cavity.
Said seal closure 6 is fixedly connected with read head mount pad 2 through guide spiro rod 5.
The round grating of numerical control deep-hole broaching machine of the present invention is following with the course of work of protector:
Read head mount pad 2 is as the installation base surface of read head 4; Said main shaft 3 is connected outputting power with counter flange 12; Said guide spiro rod 5 makes seal closure 6 can not damage grating chi 13 when mounted; Said read head mount pad 2, main shaft 3, seal closure 6, an O RunddichtringO 7, the 2nd O RunddichtringO 8, the 3rd O RunddichtringO 9, the 4th O RunddichtringO 10, counter flange 12, the 5th O RunddichtringO 14 is formed seal cavities that round grating protection is provided; Said outage and sealing-plug 11 are discharged the lubricating fluid that infiltrates circle grating seal cavity; Said read head 4 is formed circle grating measuring device structure with grating chi 13 provides closed loop to detect feedback signal.
The round grating of numerical control deep-hole broaching machine of the present invention has following characteristics with protector:
Utilize the O RunddichtringO of standard component can realize the round grating protection of big latus rectum, solved the difficulty that the round grating of the band shell protection of big latus rectum is difficult to import, and reduced system cost significantly; In the actual use, its reliability and maintainability are all fine.
Embodiment according to the present invention announced can realize the present invention, but enforcement of the present invention is not limited only to above embodiment, as substituting protector of the present invention to realize the present invention through other functionally similar protectors of employing.
