6)Quenching inducer is in guide rail quenching process, upper and lower, front and rear four of the limit deformation unit limitation guide rail in quenching process The deformation in a direction makes guide rail can only elongating or shortening in arranged on left and right sides direction;

7)For guide rail in quenching process before and after direction micro-deformation, guide rail is monitored using displacement sensor gauge head in real time and is existed The front and rear direction change in location of quenching process, and the digital control system of quenching machine is fed back to, real-time adjust automatically quenching inducer Coil front and rear direction position, the gap of the coil and guide rail that ensure quenching inducer is relatively uniform, to before ensureing guide rail, Rear direction hardening depth is relatively uniform, and by quenching the relatively uniform of the guide rail front and rear direction internal stress generated, with Front and rear direction micro-deformation of this control guide rail in quenching process.

The present invention has the advantages that:

1)In quenching, roller set is deformed using the special limit of several groups of position adjustables, with certain pressure extrusion in the upper of guide rail Below(Y-axis), front-back(Z axis), straight limit guide rail is above and below quenching process(Y-axis)It is Direction distortion, front and back(Z axis)Direction Deformation makes it can only be in left and right(X-axis)Direction elongation is shortened.

2)For the linear guide before and after quenching process(Z axis)Direction micro-deformation, it is real using displacement sensor gauge head When monitoring the linear guide before and after quenching process(Z axis)Direction change in location, feeds back to digital control system, and real-time adjust automatically is led Before and after rail quenching inducer coil(Z axis)Direction position ensures that the gap of guide rail quenching inducer coil and guide rail is relatively uniform, Before and after ensureing guide rail(Z axis)Direction hardening depth is relatively uniform, and before and after the guide rail by quenching generation(Z axis) Direction internal stress it is relatively uniform, the linear guide is controlled before and after quenching process with this(Z axis)Direction micro-deformation.

In figure:

Y direction be upper and lower described in the specification to;

Z-direction is front and rear direction described in the specification.

Specific implementation mode:

The present invention will be further described below with reference to the drawings.

Such as Fig. 1 to Fig. 3, a kind of small deformation quenching technical of the linear guide of the present invention, which is directed to the linear guide length With sectional area than big, quenching hardness is high, and internal stress is asymmetric, the case where being easily deformed, including:

1) several limit deformation units are arranged in the both sides of quenching inducer in quenching machine, and each deformation unit that limits includes four Roller 11, four rollers 11 are above and below respectively one group, and forward and backward is one group, and the roller position of downside and the roller position of rear side are equal Fixed, the roller of upside is fixedly connected with the cylinder axis of cylinder, and the roller of front side is connected with the adjusting lead screw with revolution meter; (The adjusting lead screw with revolution meter in the present invention is existing structure, adjusts the connection between lead screw and the roller seat of roller Structure is the conventional means of the prior art, therefore the present invention is not described in detail).

2)Before quenching, adjust in each limit deformation unit between the distance between upper and lower roller and forward and backward roller away from From so that the height and width of the distance between upper and lower roller and the distance between forward and backward roller to should be greater than guide rail are adopted It will be in guide rail push-in quenching inducer 2 and limit deformation unit with the push rod of quenching machine.

3)Adjustment front side adjusts lead screw, and the roller of front side is contradicted on the front end face of guide rail, and so that before and after guide rail Position is fixed, is compressed, adjustment upside cylinder stroke, and the roller of upside is contradicted on the upper surface of guide rail, and makes guide rail Upper and lower position, compression.

4)In the front and rear sides setting displacement sensor gauge head 3 of guide rail, the numerical control of displacement sensor gauge head and quenching machine System is connected;The displacement sensor gauge head 3 of forward and backward position is adjusted, guide rail trailing flank is compressed, in digital control system, by its position Value is set as gauge head with respect to origin elongation L, and Deformation control is required 0.3mm, is set as gauge head elongation alarming value(L-0.3, L+ 0.3).

5)The position forward and backward in guide rail of quenching inducer 2 is adjusted by the digital control system of quenching machine, ensures quenching induction Device is relatively uniform with guide rail front and rear sides gap.

6)Quenching inducer in guide rail quenching process, limit deformation unit limitation guide rail in the upper and lower, preceding of quenching process and The deformation of four direction afterwards makes guide rail can only elongating or shortening in arranged on left and right sides direction.

7)For guide rail in quenching process before and after direction micro-deformation, using displacement sensor gauge head, monitoring is led in real time Rail and feeds back to the digital control system of quenching machine in the front and rear direction change in location of quenching process, real-time adjust automatically quenching sense The coil front and rear direction position of device is answered, the gap of the coil and guide rail that ensure quenching inducer is relatively uniform, to ensure guide rail Front and rear direction hardening depth is relatively uniform, and opposite one by quenching the guide rail front and rear direction internal stress generated Cause, with this control guide rail quenching process front and rear direction micro-deformation.

Initial workpiece quenching is sliced(20mm thickness is cut in optional position, longitudinal cross-section), carry out guide rail raceway laser quenching hardened layer Depth, hardness test.Guide rail quenching distortion is checked.

According to guide rail both sides raceway hardening depth consistency(General requirement≤0.3mm), adjust quenching inducer Front and back position, to adjust L values;According to guide rail quenching distortion value, roller set pressing force is adjusted.Initial workpiece quenching, quality are carried out again Detection, until meeting hardening depth consistency, the requirement of quenching distortion value.Batch is carried out according to initial workpiece quenching process parameters Guide rail continuous quenching produces, in the process 1 inspection deflection of every 10 sampling observations, and every 40 are taken out 1 progress raceway laser quenching hardened layer Depth consistency inspection ensures batch quenching process quality stability.

The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as the present invention's Protection domain.
