Description
Technical field
The utility model relates to a kind of balls of ball screw assembly, to slide imitative experimental appliance.
Background technique
Ball screw assembly, is the important transmission parts of numerically-controlled machine tool, precision instrument and military industry equipment, and wherein roller is most main
The transmission wanted and bearer, it directly affects the transmission accuracy and service life of ball screw assembly,.Ball is stressed upon spiral roll
Rolled in road, sliding movement when, ball and raceway can be worn, and cause the gap of ball screw assembly, to increase, transmission accuracy
It reduces, and then the service life and machining accuracy of influence numerically-controlled machine tool etc..Therefore, the ball for being badly in need of developing ball screw assembly, is sliding
Imitative experimental appliance is moved, measures pressure, the relationship of time that the abrasion of ball is born with it will pass through experiment, and then be ball
Design, processing and the maintenance of lead screw pair provide reliable experimental basis.
Utility model content
The purpose of the utility model is to provide a kind of balls of ball screw assembly, to slide simulated experiment, which can load not
Same load, to simulate the wear process that ball sliding generates under different pressures, the wear process for measuring ball is born with it
Pressure relationship, and then provide reliable experimental basis for the design, processing and maintenance of ball screw assembly,.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of ball of ball screw assembly, slides mould
Draft experiment device, composition is:
The table top of pedestal is longitudinally provided with two parallel spherical guides, and the drive end of the lead screw shaft of ball screw assembly, passes through
Bearing block one is mounted on the side of pedestal table top；The driven end of lead screw shaft is mounted on the another of pedestal table top by bearing block two
Side；Motor output shaft is connected by shaft coupling with the drive end of lead screw shaft；Ball rack is led by the sliding block of its underpart with ball
Rail is slidably connected, and the screw of ball screw assembly, is fixed on the lower part of ball rack；
Bolt block is fixed on the table top of the ball rack, longitudinal bolt is mounted on bolt block by bearing,
Probe support is threaded on bolt again；One end of guide rod is fixedly connected with bolt block, and the other end of guide rod, which passes through, to be visited
The pilot hole of head support；The probe support is also vertical to be threaded with pressure screw rod, and pressure screw rod passes through pressure sensor
Ball contact is connected, and ball contact is located at the surface of lead screw shaft.
The working process and principle of the utility model are:
Bolt on swing roller rack drives probe support to vertically move along guide rod, realizes the longitudinal direction of ball contact
Position is adjusted；Rotation pressure screw rod moves down it, and ball contact is driven to be moved in the raceway of lead screw shaft；Continue rotation to apply
Screw rod is pressed to apply the precompression of setting to ball contact；The data of precompression are read by pressure sensor.
Start motor, under the drive of the motor, lead screw shaft and the screw of ball screw assembly, relatively rotate, and make ball table
While frame is vertically moved along spherical guide, relative rolling, sliding occur in the raceway of lead screw shaft for ball contact, to carry out
The sliding wear test of ball.In experimentation, the data of pressure sensor are recorded in real time, until completing the reality of setting time
It tests.
Compared with prior art, the utility model has the beneficial effects that
One, by pressure relative rolling, the process of sliding are occurred in the raceway of lead screw shaft for this experimental bench by ball contact,
Preferably simulate slipping of the ball in ball screw assembly, raceway；Ball contact can be applied by pressure screw rod different
Precompression, ball screw assembly, ball slipping and wear process under load pressure can be simulated, and then obtain ball
The relationship for the pressure that wear process is born with it.Replace ball contact you can get it different materials, the slipping of specification and mill
Damage process.And then reliable experimental basis is provided for the design, processing and maintenance of ball screw assembly,.For research ball screw assembly,
Ball sliding and abrasion provide experimental data.
Two, the lengthwise position of ball contact, vertical position can be adjusted by bolt, pressure screw rod respectively, thus side
Just the contact for replacing different size and material, show that the slipping and wear process of different materials, specification, versatility are good.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
