Abstract
The utility model relates to a protective device for the grinding wheel of the grinding machine with a circle inside. When the grinding wheel is withdrawn from the grinding area, the grinding wheel protective device covers the surface of the grinding wheel, and is reliably connected with the in and out work piece of the grinding wheel, guaranteeing the safety of the operating stuffs, wherein, the utility model comprises a hydraulic cylinder, a pull rod of a piston rod of the hydraulic cylinder; the utility model is characterized in that: the pull rod is of rotary connection with the rotor one end of which is connected with the cover of the grinding wheel by a fixture block and a connector; a radio block is arranged at the other end of the rotor; near to the rotor is positioned a sensor which is of electronically controlled connection with the solenoid valve which controls the hydraulic cylinder.
Description
(1) technical field
The utility model relates to the accessory of internal grinder, is specially Internal Grinder Wheel Guard.
(2) background technology
Internal grinder is to be used for grinding part endoporus, and emery wheel is littler than the diameter of bore of institute grinding.Processing 100mm is during with interior hole, because grinding wheel diameter is less, this just requires emery wheel to have one to compare high rotational speed.The linear velocity of emery wheel is in 35m/s during general inner hole grinding, but part processing efficient and machining accuracy under this speed are lower, refused by increasing user, the requirement of emery wheel high speed at present is more urgent, and the linear velocity of emery wheel has been brought up in the 60m/s scope.But emery wheel is subjected to the restriction of conditions such as manufacturing process, environment for use, force-bearing situation, emery wheel inside stays crackle easily, when lathe carries out grinding, the emery wheel just inner surface of part to be processed contains, when emery wheel withdraws from grinding area, emery wheel is exposed in face of the operating personnel fully, and the raising of grinding speed stays great hidden danger to operating personnel.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of Internal Grinder Wheel Guard, and when emery wheel withdrawed from grinding area, wheel face contained by the emery wheel protector, and protector and emery wheel pass in and out workpiece and have chainly reliably, guarantees operating personnel's safety.
Its technical scheme is such: it comprises hydraulic cylinder, the piston rod cylinder lever connecting rod of described hydraulic cylinder, it is characterized in that: described pull bar and gyroaxis are rotatably connected, one end of described gyroaxis is connected with wheel guard by fixture block, connector, the other end of described gyroaxis is equipped with the sender piece, at the sensor that is attached with of described sender piece, described sensor electricly connects with the magnetic valve of the described hydraulic cylinder of control.
It is further characterized in that: described sensor is a noncontacing pickup.
The utility model is installed on the pedestal of lathe, the rectilinear motion of hydraulic cylinder output converts the gyration of gyroaxis to by pull bar, according to the message of sender piece, sensor can accurately be judged falling down and lifting of fixture block, so just can finish protective hood of grinding wheel reliably and contain emery wheel.

Fig. 1 is a vertical view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is front view of the present utility model and partial sectional view;
Fig. 4 is that the B-B of Fig. 3 is to cutaway view.
(5) specific embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises hydraulic cylinder 13, piston rod 14 cylinder lever connecting rods 10 of hydraulic cylinder 13, pull bar 10 is rotatably connected by bearing pin 9 with gyroaxis 3, one end of gyroaxis 3 is connected with wheel guard 8 by fixture block 7, connector, the other end of gyroaxis 3 is equipped with sender piece 4, sender piece 4 be attached with noncontacing pickup 5, noncontacing pickup 5 electricly connects with the magnetic valve of control hydraulic cylinder 13.1 for screw, 18 is pedestal for end cap, 17 for support, 11,12 is respectively the fuel feed hole of oil cylinder and oil outlet, 15 for screw, 16 for pedestal, 6 for cover plate, 2.Below in conjunction with accompanying drawing course of action of the present utility model is described further: the distance between noncontacing pickup 5 and the sender piece 4 is in certain scope the time, sensor 5 can detect signal, when emery wheel stops the workpiece grinding, the signal that the digital control system of grinding machine sends according to sensor 5 is accurately judged the distance between sender piece 4 and the sensor 5, and then the position of extrapolating wheel guard, by the solenoid control oil cylinder, make piston rod drive the control of pull bar realization then to wheel guard.Sender piece in the utility model can select to use iron block.
Claims (2)
1, Internal Grinder Wheel Guard, it comprises hydraulic cylinder, the piston rod cylinder lever connecting rod of described hydraulic cylinder, it is characterized in that: described pull bar and gyroaxis are rotatably connected, one end of described gyroaxis is connected with wheel guard by fixture block, connector, the other end of described gyroaxis is equipped with the sender piece, and at the sensor that is attached with of described sender piece, described sensor electricly connects with the magnetic valve of the described hydraulic cylinder of control.
