Abstract

A lathe includes a machine support, a work table, two cross beams and a feeding device. The work table is positioned on the machine support. The two cross beams are mounted on the machine support above the work table. The feeding device includes a cutter. The feeding device is slidably assembled between the two cross beams to obtain support from opposite sides of the two cross beams.

First claim

What is claimed is:

1. A lathe, comprising:
a machine support;
a work table positioned on the machine support;
two cross beams separately mounted on the machine support above the work table; and
a feeding device comprising a cutter,
wherein the feeding device is slidably assembled between the two cross beams to obtain support from opposite sides of the two cross beams, the feeding device further comprises a feeding mechanism, a mounting seat sleeved on the feeding mechanism and a tool holder slidably positioned in the mounting seat, the mounting seat is slidably assembled between the two cross beams, the cutter is fixedly installed on the tool holder, and the feeding mechanism drives the tool holder and the cutter to move back and forth, each of the two cross beams comprises a sliding surface, the two sliding surfaces of the two cross beams are positioned face to face, two second sliding rails are positioned on the sliding surfaces, two second guiding blocks are positioned parallel on each of the opposite sides of the mounting seat positioned adjacent to the cross beams, and the two second guiding blocks slidably engage with the two second sliding rails.

2. The lathe of claim 1 , further comprising a rotating driver to rotate the work table.

3. The lathe of claim 1 , wherein the machine support comprises a base and two support bodies positioned substantially parallel on the base, and the two cross beams slidably mounted on the pair of support bodies.

4. The lathe of claim 3 , wherein a pair of first sliding rails are positioned substantially parallel on each of the pair of support bodies away from the base, each of the two cross beams comprises a support portion and two fixing portion positioned at opposite ends of the support portion, and two first guiding blocks are positioned on each of the two fixing portions to slidably engage with the pair of first sliding rails.

5. The lathe of claim 4 , wherein the lathe further comprises two driving mechanisms for driving the cross beams to move along the pair of first sliding rails, each of the two driving mechanisms comprises a rotor and a stator, a first receiving groove is formed on each of the pair of support bodies between the pair of first sliding rails, the stator of each of the two driving mechanisms is received in the first receiving groove, and the rotor of each of the two driving mechanisms is fixedly mounted on each of the fixing portions of one cross beam.

6. The lathe of claim 1 , wherein the feeding device further comprises a mounting seat and a tool holder positioned in the mounting seat, the mounting seat is slidably assembled between the two cross beams, and the cutter is fixedly installed on the tool holder.

7. The lathe of claim 1 , wherein the lathe further comprises two driving mechanisms for driving the feeding device to move along the two second sliding rails, each of the two driving mechanism comprises a stator and a rotor; a second receiving groove is formed on each two of second sliding rails, the stator of each of the two driving mechanisms is received in one second receiving groove, and each rotor of the two driving mechanisms is fixedly mounted on each of the opposite sides positioned adjacent to the cross beams of the feeding device.

8. A lathe, comprising:
a machine support;
a work table positioned on the machine support;
two cross beams mounted on the machine support above the work table; and
a feeding device comprising a cutter,
wherein the feeding device is slidably assembled between the two cross beams to obtain support from opposite sides of the two cross beams, and the feeding device is capably of being driven to move along the three axes, X, Y, and Z, the feeding device further comprises a feeding mechanism, a mounting seat sleeved on the feeding mechanism and a tool holder slidably positioned in the mounting seat, the mounting seat is slidably assembled between the two cross beams, the cutter is fixedly installed on the tool holder, and the feeding mechanism drives the tool holder and the cutter to move back and forth, each of the two cross beams comprises a sliding surface, the two sliding surfaces of the two cross beams are positioned face to face, two second sliding rails are positioned on the sliding surface, two second guiding blocks are positioned parallel on each of the opposite sides of the mounting seat positioned adjacent to the cross beams, and the two second guiding blocks slidably engage with the two second sliding rails.

9. The lathe of claim 8 , further comprising a rotating driver to rotate the work table.

10. The lathe of claim 8 , wherein the machine support comprises a base and a pair of support bodies positioned substantially parallel on the base, and the two cross beams are slidably mounted on the pair of support bodies.

11. The lathe of claim 10 , further comprising a pair of first sliding rails positioned substantially parallel on each of the pair of support bodies away from the base, each of the two cross beams comprises a support portion and two fixing portion positioned opposite ends of the support portion, and two first guiding blocks are positioned on each of the two fixing portions to slidably engage with the pair of first sliding rails.

12. The lathe of claim 11 , further comprising two driving mechanisms for driving the cross beams to move along the pair of first sliding rails, each of the two driving mechanisms comprises a rotor and a stator, a first receiving groove is formed on each of the pair of support bodies between the pair of first sliding rails, the stator of each of two driving mechanisms is received in the first receiving groove, and the rotor of each of the two driving mechanisms is fixedly mounted on each of the fixing portions of one cross beam.

13. The lathe of claim 8 , wherein each of the two cross beams comprises a sliding surface, the two sliding surfaces of the two cross beam are positioned face to face, two second sliding rails are positioned on the sliding surface, two second guiding blocks are positioned substantially parallel on each side of the opposite sides of the mounting seat which are positioned adjacent to the cross beams, and the two second guiding blocks slidably engage with the two second sliding rails.

14. The lathe of claim 13 , further comprising two driving mechanisms for driving the feeding device to move along the two second sliding rails, each of the two driving mechanisms comprises a stator and a rotor; a second receiving groove is formed on each of the two second sliding rails, the stator of each of the two driving mechanisms is received in the second receiving groove, and the rotor of each of the two driving mechanisms is fixedly mounted on each of the opposite sides positioned adjacent to the cross beams of the mounting seat.
