A kind of machine tool chief axis axial float failure warning device; It is characterized in that: the alarming device that can report to the police when the tail end face of said machine tool chief axis is equipped with the main shaft play; Said alarming device is installed in the main spindle box sidewall end and covers, and said end cap is fixedly mounted on the main spindle box shell.
The utility model can also adopt following technical measures:
Machine tool chief axis axial float failure warning device according to claim 1 is characterized in that: said alarming device adopts the once-through type alarming device, mainly comprises the shake pin of gathering the play signal; Said shake pin is installed in the end caps of main spindle box, and the shake needle gage has with a certain distance from the main shaft end face, current-limiting resistance of said shake pin series connection; Current-limiting resistance connects the trigger electrode of one-way SCR, a parallelly connected dividing potential drop electric capacity between trigger electrode and the power cathode, one-way SCR anode connection fuse; Fuse connects alarm; Alarm series connection press button, press button connects the positive pole of dc source, and the negative pole of dc source connects the negative electrode of one-way SCR.
Said shake needle gage is from main shaft end face 2 ~ 3mm.
Said shake pin place mounting spring.
Said alarming device adopts the AC type alarming device, mainly comprises the 220V AC power, a series connection microswitch, a button and alarm between the 220V AC power; Said microswitch is installed in the end caps of main shaft, apart from main shaft end face certain distance.
Said microswitch is apart from main shaft end face 2 ~ 3mm.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Can reduce other hidden danger or accident that plant equipment main shaft fault can not in time be found and warn and bring effectively; Can make the safety in production and the High-efficient Production of company be able to ensure like this, and its stable performance, alarm failure effectively in time; The while long service life, device is changed advantages such as convenient.
Description of drawings
Fig. 1 is the utility model embodiment 1 circuit diagram;
Fig. 2 is the utility model embodiment 2 circuit diagrams.
Among the figure: 1, machine tool chief axis; 2, alarming device; 2-1, shake pin; 2-2, microswitch; 3, spring.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Embodiment 1: see also Fig. 1; A kind of machine tool chief axis axial float failure warning device; It is characterized in that: the alarming device 2 that can report to the police when the tail end face of said machine tool chief axis 1 is equipped with the main shaft axial float; Said alarming device is installed in the main spindle box sidewall end and covers, and said end cap is fixedly mounted on the main spindle box shell.Alarming device described in the present embodiment adopts the once-through type alarming device; Mainly comprise the shake pin 2-1 that gathers the play signal; Said shake pin is installed in the end caps of main spindle box; The shake needle gage has with a certain distance from the main shaft end face, and the shake needle gage to leave the main shaft endface position be mechanical sliding adjustable, the size of this distance is generally at 2 ~ 3mm.The current-limiting resistance of 220 a Ω/1W of said shake pin series connection, current-limiting resistance connects the trigger electrode of one-way SCR, and one-way SCR adopts BT151-500R; A parallelly connected dividing potential drop electric capacity between trigger electrode and the power cathode, capacitance size is 0.22 μ F/63V, the one-way SCR anode connects fuse; The fuse blows electric current is 1A; Fuse connects alarm, and it is LTE-1084J that alarm adopts model, alarm series connection press button; Press button connects the positive pole of 12V dc source, and the negative pole of 12V dc source connects the negative electrode (BT151-500R) of one-way SCR.
In order to ensure not fractureing said shake pin place mounting spring 3 at main shaft axial float fault time shake pin.
Embodiment 2: see also Fig. 2; A kind of machine tool chief axis axial float failure warning device; The alarming device 2 that can report to the police when the tail end face of said machine tool chief axis 1 is equipped with the main shaft axial float; Said alarming device is installed in the main spindle box sidewall end and covers, and said end cap is fixedly mounted on the main spindle box shell.Alarming device described in the present embodiment adopts the AC type alarming device, mainly comprises the 220V AC power, a series connection microswitch 2-2, a button and alarm between the 220V AC power; Alarm employing model is LTE-1081J in the present embodiment; Said microswitch is installed in the end caps of main shaft; Apart from main shaft end face certain distance, said microswitch is apart from main shaft end face 2 ~ 3mm, and microswitch contact distance main shaft endface position is mechanical sliding adjustable.
Because former alarm just to the electric part fault, does not have warning function to the mechanical part fault, for addressing this problem so design the utility model device.What this product was directed against is when machine tool chief axis generation axial float, can in time report to the police, to reach the purpose of safety in production.This product one has two kinds, and a kind of is once-through type, and a kind of is AC type.What once-through type adopted is that the shake pin triggers the IGCT conducting, connects direct current and reports to the police.AC type triggers microswitch for the play main shaft, and turning circuit sends warning.Like this, used the function of alarm to solve the defective that mechanical breakdown can not in time be found and warn.
The utility model can reduce other hidden danger or the accident of bringing after the plant equipment main shaft fault effectively in sum; Can make the safety in production and the High-efficient Production of company be able to ensure like this; And its stable performance; Alarm failure effectively in time, long service life simultaneously, device is changed advantages such as convenient.
