Description
Technical field
The present invention is a kind of linear actuator, espespecially a kind of linear actuator for having Abrasion detecting.
Background technology
Linear actuator is often referred to ball screw or linear slide rail, and the ball screw or linear slide rail by moving body,
Major axis and rolling member are constituted, and linear actuator is in order to have accurate positioning precision and a high rigidity, therefore moving body, major axis
And between rolling member certainly will with the presence of a precompression, and the precompression refer to when linear actuator is non-loaded moving body,
Between major axis and rolling member or mutual stress, and gapless is present between moving body, major axis and rolling member；And there is precompressed
When the linear actuator of power is applied to board, the rigidity and positioning precision of board can be allowed to be lifted, therefore the workpiece for being processed is also
There can be good quality, therefore the linear actuator with precompression is extremely important for precision machining table
Core component.
Hold above-mentioned, in order to the precompression for preventing the linear actuator with precompression disappears, and cause Linear transmission to fill
The positioning precision and rigidity put are reduced, therefore No. 7299703 Patent Case of U.S. Publication discloses one kind and utilize displacement meter to include contact
Formula, contactless, LVDT, optical fiber type measure the device in moving body, gap between major axis and rolling member, when gap produces change
When also represent precompression relatively and also produce change, therefore can real-time informing user carry out shutdown inspection, to prevent board to lose precision
Also persistently process workpiece, and cause workpiece quality bad, seriously then cause batch workpiece to scrap, so monitoring device is deposited in fact
Necessity.But this monitoring device has still suffered from problems with point：
Measuring instrument equipment is sufficiently expensive, is such as installed in that cost on linear actuator is too high, and client's acceptance is not high.
The measurement mode of this kind of structure actually makes very difficult, and measure position easily with foreign matter produce interference and
Corrupted or surface have oil stain to adhere to, and cause the data of monitoring and actually have drop.
The content of the invention
In view of above mentioned problem, present invention is primarily aimed at：A kind of low cost of research and development, accuracy rate Abrasion detecting dress high
Put, whether lose precompression or produced abrasion to detect linear actuator.
To reach above-mentioned purpose, solution of the invention is：
A kind of linear actuator for having Abrasion detecting, comprising：Comprising：One major axis, it is strip structure, the major axis
Outer surface is provided with rolling channel；One moving body, it is provided with the sleeved part being arranged for the major axis, and the inner edge surface of the sleeved part is provided with relatively
The rolling groove of the rolling channel, the rolling channel constitutes a load path with rolling groove；Multiple rolling members, located at the load path；One
Abrasion detecting component, located at the moving body, the Abrasion detecting component is made up of a magnetic and an insulator, the magnetic one end
Outer surface with respect to the major axis is set, and defines the end for absorption is provided with the insulator between end, and the magnetic and the moving body；
One alarm modules, there are two connection ends to be electrically connected with the moving body and the magnetic for it；The absorption end adsorb the major axis,
Abrasion iron filings between moving body and rolling member, control whether the alarm modules turn on by the iron filings number, such as the magnetic
The amount of the iron filings between moving body has more to contacted the magnetic and the moving body, then turn on the alarm modules, and triggering should
Alarm modules point out alerting.
Preferably, the moving body is provided with a mounting hole, the mounting hole is provided with internal thread, and the outer edge surface of the insulator is provided with outer
Screw thread, and the insulator is screw-locked at the mounting hole.
Preferably, the absorption end of the magnetic is set with respect to the rolling channel.
Preferably, the alarm modules include a power supply and warning component, the power supply is electrically connected with the warning component, and defeated
Go out two connection ends.
Whereby, the present invention adsorbs the major axis, the abrasion iron filings between moving body and rolling member by the magnetic, and then sentences
It is disconnected that whether abrasion have been produced between the major axis, moving body and rolling member three, contact the magnetic when the iron filings of abrasion become more
During with the moving body, that is, the alarm modules are turned on, then lose the omen of precompression soon for linear actuator, therefore by alarm mould
Block sends alerting and informs that user need to notice the precompression state of linear actuator, and Abrasion detecting device of the invention is sharp
With low cost magnetic and simple circuit design, reach actively inform linear transmission module whether may purpose, changed
It is apt to the problem of prior art high cost and because external greasy dirt or foreign matter draws the problem for ringing sensor accuracy of judgement degree.
