Description

A kind of saddle of machining center

Technical field

This utility model is related to a kind of vertical machining centre, especially a kind of saddle of machining center.

Background technology

At present, the mounting means of the saddle translator unit of most machining center is all motor side distribution support, motor The regulation of seat adjusts the high and low position of motor cabinet by the cushion block below motor cabinet, and the tail end of running part matches somebody with somebody bearing support block, The regulation of same tail end is also required to the height up and down that cushion block below adjusts bearing support block.The processing essence of past plant equipment Degree error is larger, and the higher tooling cost of precision is too high.And this mode compensate for the error of machining, but The spacer thickness of the bearing support block of the motor cabinet pad and screw mandrel support end of constantly regulate motor side is needed in assembling mode. Working strength is high, and needs higher technical merit.

The saddle material of machining center is generally foundry goods, and the centre position of saddle needs to install motor cabinet and bearing support block And drive lead screw group, therefore saddle centre position needs to reserve position.The exactly one U-shaped foundry goods do not closed from terms of end face, and this Plant design yielding, affect machine tool accuracy.

Chinese patent once disclosed a kind of vertical machining centre entirety saddle (201320759450.X), including saddle master Body, is recessed body groove in the middle of saddle main body, and the two ends branch of the body groove is provided with bearing block and the fixation of fixing bearing The motor cabinet of motor, the saddle main body, bearing block and motor cabinet are the integrally formed monolithic construction of foundry goods.

Chinese patent once disclosed a kind of vertical machining centre integral type saddle (201420623244.0), including saddle master Body, the major trough body being arranged in saddle main body, arrange the bearing block of fixing bearing in the major trough body Single port, and the other end is arranged The motor cabinet of fixed motor, is additionally provided with the bearing block of another fixing bearing, the two bearings on the inside of the motor cabinet Seat, the pilot hole axis coaxle on motor cabinet, the casting that described saddle main body, two bearing blocks and motor cabinet are formed in one Part structure.

Utility model content

The purpose of this utility model is that the saddle structure to machining center is improved, there is provided a kind of mounting means letter It is single, the on-deformable structure of saddle.

To reach above-mentioned purpose, the solution that this utility model is taken is：A kind of saddle of machining center, it includes saddle Seat main body, integrally has additional pedestal one, pedestal two, pedestal three, in pedestal one, pedestal two, pedestal three in the middle of saddle main body O-shaped hole is provided with all, screw component is directly installed in saddle main body by pedestal one, pedestal two, pedestal three.

Described pedestal three installs the supporting bearing base of screw mandrel support end, and described pedestal two is installed and bears radial direction and axial direction The bearing block of power, described pedestal one install motor by motor plate.

The end face of described pedestal three has mounting hole site, has two installing holes in supporting bearing base.

The end face of described pedestal two has mounting hole site, and bearing block end face has six installing holes, adjusts bearing block 10 Position up and down and fixed bearing block.

The end face of described pedestal one has four installing holes, is the position up and down of motor for regulation motor plate Put.

Transmission agency is summarized as follows：Described motor plate is arranged on pedestal end face, and motor is again installed in the end of motor plate Face.Screw component two ends are provided with spring bearing and bear the bearing of radial direction and axial force, and spring bearing is arranged on spring bearing In seat groove, supporting bearing base is locked in three end face of pedestal again.Bear radially to be arranged on the bearing of axial force and bear radial direction and axle Into the bearing block groove of power bearing, bearing gland adjusts good position, and locking nut locks bearing, shaft coupling by bearing gland The torsion that driving motor is initiated to screw component, rotary screw rod component realize transmission agency.

The saddle structure of this kind of machining center compared with prior art, has the positive effect that：The structure of saddle is from U-shaped Design is changed to O-shaped, increased the integral rigidity of saddle, improves the stability of lathe.From original Split type electric support, support Bearing base is changed to existing overall structure, simple on mounting means, need not adjust the thickness of cushion block to ensure precision, to dress Skill set requirements with personnel are reduced.
