Description
Technical field
The present invention relates to linear guidance device technical fields, roll more particularly, to a kind of high guiding performance pearl, column mixing narrow
Width linear guide.
Background technique
Linear guide is with the high and low abrasion of its transmission efficiency, the kinematic accuracy items advantage such as good, it has also become must can not in lathe
Few crucial link member.Linear guide is also known as sliding rail, linear guides, linear slide rail, is used for straight reciprocating motion occasion, possesses
Nominal load more higher than linear bearing, while certain torque can be undertaken, high-precision can be realized in high-load situations, this
Linear motion.
The processing technology that linear guide High-speed machining has been generally considered and has improved yield, reduced manufacturing cost, straight line are led
Rail, which is used primarily on automated machine, compares more, image height precise numerical control machine, bending machine, laser-beam welding machine etc..Linear guide
Mainly in the relatively high mechanical structure of required precision, since guiding performance is machine vibration problem and lathe damping in lathe
Main source, so the high guiding performance of linear guide also becomes lathe towards high-precision, high speed development main " roadblock ".It is existing
There are four column ball-types and four column roller-type linear guides, when bearing high load and making high-speed slide, due to the guiding essence of guide rail
Degree is not high, and guiding accuracy is the order of accuarcy of its motion profile when moving link is moved along guide pass, and guide rail and installation pedestal are deposited
In gap, so that the vibration of lathe be made to increase, the kinetic damping of lathe is increased, and directly affects the machining accuracy of lathe.
To solve the above problems, needing to design, a kind of high guiding performance pearl, column mixing rolls narrow linear guide is this field
One urgent problem to be solved of technical staff.
Summary of the invention
It is an object of the invention to overcome existing four column ball-type and four column roller-type linear guides, high load is being born simultaneously
When making high-speed slide, since the guiding accuracy of guide rail is not high, guiding accuracy is that it moves rail when moving link is moved along guide pass
There are gaps for the order of accuarcy of mark, guide rail and installation pedestal, so that the vibration of lathe be made to increase, the kinetic damping of lathe is increased,
This technical problem of the machining accuracy of lathe is directly affected, provides a kind of high guiding performance pearl, column mixing rolls narrow straight line and leads
Rail solves above-mentioned technical problem.
The technical solution of the present invention is to provide a kind of high guiding performance pearl, column mixing to roll narrow linear guide, comprising: guide rail
1 and matched sliding block 2,1 top surface of guide rail be subject to move the main motion face of heavily loaded object normal pressure, have the big roller 3 of a column
Positioned at 1 top surface of guide rail, 1 two sides of guide rail are the guide surfaces of bearing capacity, have two column balls 4 to be each positioned at side, and constrained motion object is left
Right and radial rotary deviation is inclined to, and the guide rail 1 is equipped with threaded mounting hole 5 and installation pedestal is fixed, threaded mounting hole 5
Spacing be 0.5~10 times of length, 2 left and right ends of sliding block set that there are two recoverable capsules 6.
The further 5 top countersunk head depth of threaded mounting hole is 2.5~46mm.
The flatness of the further guide rail 1 is 0~0.015mm.
The further 1 main motion face groove width of guide rail and big roller 3 have the gap 0.1mm.
The further guide rail 1 and 2 surface hardness of sliding block are between HRC60-65.
The surface roughness of the further guide rail 1 is less than Ra:0.8.
Compared with prior art, the beneficial effect comprise that guide rail be equipped with threaded mounting hole and installation pedestal into
Row is fixed, and the spacing of threaded mounting hole is 0.5~10 times of length, reduces the gap of guide rail and installation pedestal, and reduction is led
Vibrating noise between rail and installation pedestal keeps the fixation of guide rail and guiding accuracy higher, when linear guide carries higher weight,
The accuracy that can guarantee the linearity of sliding trace and positioning when carrier moves along the rail, can be improved and move along guide pass
When its motion profile order of accuarcy, further promoted high-grade, digitally controlled machine tools machining accuracy, make the kinematic accuracy of linear guide
It significantly increases.
The present invention is 0~0.015mm design by the flatness of guide rail, can further shorten linear guide clipping room
Gap reduces the vibration of linear guide, linear guide is made to have preferable bearer properties, Ke Yicheng by installing the diminution in gap
By the power and torque load of different directions, the applicability of linear guide is further promoted, while also improving the essence of linear guide
Degree.
The present invention is designed between HRC60-65 by guide rail and shoe surface hardness, when linear guide is done in assigned direction
When linear reciprocating motion, because of the promotion of material hardness, the lifting capacity of linear guide is made to have obvious promotion, while made straight
The abrasion of line guide rail substantially reduces, and has given full play to the service performance of linear guide, further improves the use of linear guide
Service life.
The present invention is less than Ra:0.8 by the surface roughness of guide rail, can substantially reduce the friction of linear guide.Straight line
Guide rail is in carrying higher load, when doing linear reciprocating motion by given direction, if surface roughness is higher, and contact surface friction
It damping larger, makes contact surface strong friction, form scratch, the passage of the abrasion of linear guide at any time is gradually increased, and this stroke
Trace will form irreversible injury to linear guide, will certainly shorten the service life of linear guide.
