Background technology:
Electric driving tool post is the critical piece of Digit Control Machine Tool, and the cutting tool that machining is required is installed on electric driving tool post.After machine tool numerical control system sends and selects the cutter instruction, the electric driving tool post rotation, position detecting device with the feedback of knife rest rotating position signal in machine tool numerical control system, when turning to corresponding cutting tool position, machine tool numerical control system sends instruction, makes the counter-rotating of knife rest motor, drives electric driving tool post locking, after digital control system receives the knife rest locking signal that position detecting device sends, the lathe process of being allowed for access.
The electric driving tool post position detecting device is the sensor of knife rest station signal and locking signal in fact, and the signal correctness that is sent will influence plant equipment and personal safety.
The station detection means of electric driving tool post is made up of tool rest code tray and photo-electric knife rest encoder that magnetic switch, Hall element are formed usually.The position detecting device of existing electric driving tool post all is installed on the tool holder body, is example with vertical knife rest.Control device is installed on the top of knife rest, bear cutting and tool changing vibrations, and be among the wet environment of cooling fluid formation, work under the influence of several thermals source (conduction that heat in metal cutting is conducted, the motor feels hot etc.), facts have proved the electric driving tool post station checkout gear of forming by electronic devices and components, hold bad working environment such as can't stand high temperature, humidity, impact shock.
The utility model content
In order to solve the problem that prior art exists, the purpose of this utility model provides a kind of position detecting device that is used for the Digit Control Machine Tool electric driving tool post that can bear bad working environment such as high temperature, humidity, impact shock, prevent the contact disengaging.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
The position detecting device that is used for the Digit Control Machine Tool electric driving tool post, it comprises main shaft and insulator foot, be equipped with on the insulator foot and can form the main shaft that is rotatably assorted with it, on the different circumference of insulator foot, be inlaid with public conductive sleeve and cutter spacing conductive sleeve in two circular holes with respect to axis, by lead two conductive sleeves are linked to each other, be fixed with the strip conductor dish on the main shaft, the insulation board of strip conductor dish is provided with public strip conductor and cutter spacing strip conductor, stage clip is housed in the conductive sleeve, and stage clip is provided with and the contacted steel ball of strip conductor.
Described main shaft directly is plugged in the insulator foot.
Described lead is arranged on to be carved in the metallic channel that digs on insulator foot.
The circumference of described public strip conductor and the movement locus of public conductive sleeve are concentric circles; The movement locus of the circumference of cutter spacing strip conductor and cutter spacing conductive sleeve is a concentric circles.
Advantage and the effect that the utlity model has are:
1,, therefore is different from tool rest code tray and photo-electric knife rest encoder that magnetic switch, Hall element are formed because the critical piece that the utility model is used for the position detecting device of Digit Control Machine Tool electric driving tool post is machine components.Can bear bad working environment such as high temperature, humidity, impact shock.
2, between steel ball of the present utility model and the track be the rolling friction mode, wear-resisting, long service life.
3, the utility model utilizes stage clip with steel ball jack-up, is direct force way up and down, and contact point is reliably contacted, and is difficult for breaking away from the accuracy height of checkout gear.
