Abstract
The utility model discloses a bearing pedestal device of a machine tool feed system. Two supporting seats are arranged on a lathe bed and are integrated with the lathe bed. Reinforcing ribs are arranged in front of and behind the supporting seats. The upper portion of each supporting seat is provided with a notch, wherein the diameter of the notch is larger than the diameter of a lead screw. The two ends of the lead screw are arranged in the notches of the two supporting seats in a supported mode. A bearing pedestal used for installing a bearing is mounted on the outer side of each supporting seat. When feed movement starts, generated force is transmitted to the supporting seats and the reinforcing ribs, and therefore the bearing pedestal device can bear large force and is simple in structure and convenient to assemble.
Description
Technical field
The utility model relates to a kind of lathe, especially relates to a kind of bearing holder device of Machine Tool Feeding System.
Background technology
There are direct relation in the assembly precision of feed system and the precision of lathe and life-span, and the bearing block form in traditional feed system is high to center height and the requirement of end contact-making surface flatness, and difficulty of processing is larger.Simultaneously, because bearing seat is subject to tensile force, require the rigidity of leading screw seat enough large, bring certain difficulty for processing, assembling, the part of large volume has increased production cost simultaneously.
Summary of the invention
The purpose of this utility model is: the bearing holder device that a kind of Machine Tool Feeding System simple in structure, easy to assembly is provided.
The technical solution of the utility model is: comprise leading screw, bearing block and lathe bed, have two supporting seats with the lathe bed one on the lathe bed, the front and back of supporting seat have reinforcement, supporting seat top has the gap greater than the leading screw diameter, the leading screw two end supports is in the gap of two supporting seats, bearings mounted bearing block is equipped with in the outside of each supporting seat, and bearing block is bolted to connection on supporting seat, and bearing, spacer and locking nut are equipped with respectively in the leading screw two ends.
Described reinforcement is fastened on the lathe bed.
Described bearing block is a thin-wall sleeve.
The beneficial effects of the utility model: the utility model is because supporting seat and lathe bed one, the leading screw two end supports is in the gap of two supporting seats, supporting seat is supported by reinforcement, bearing block changes a thin-wall sleeve into, and structure is optimized, and processing technology is simple, precision is easy to guarantee, reduce the bearing block volume, production cost is low, economizes on resources and the energy.When feed motion occured, the power of generation was delivered to supporting seat and reinforcement, can bear larger power, and assembled simple and conveniently, had improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Can find out from the top view of structural representation of the present utility model shown in Figure 1 and Fig. 2, the utility model comprises leading screw 7, bearing block 3, bearing 4, spacer 2, locking nut 1 and lathe bed 9.In the position of needs assembling leading screw 7,6, two supporting seats of lathe bed 9 protruding a pair of supporting seats 6 are integrated with lathe bed 9, the front and back of supporting seat 6 have reinforcement 8, reinforcement 8 is supported on the inboard of two supporting seats 6, and reinforcement 8 can be integrated with lathe bed 9, also can be by bolted on lathe bed 9.Supporting seat 6 tops have the gap greater than leading screw 7 diameters, leading screw 7 two end supports are in the gap of two supporting seats 6, and bearing block 3 is equipped with in the outside of each supporting seat 6, and bearing block 3 is a thin-wall sleeve, bearing block 3 end faces contact with supporting seat 6, are bolted to connection on supporting seat 6.Bearing 4, spacer 2 and locking nut 1 are equipped with respectively in leading screw 7 two ends, and in the bearing 4 installation shaft bearings 3, spacer 2 is equipped with in the inboard of bearing 4 and the outside, and locking nut is installed in spacer 2 outsides in the outside.Then leading screw 7 and the prepackages such as bearing 4, bearing block 3 place on the supporting seat 6 on the lathe bed 9, last locking nut 1.
