Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically a boring mechanism that is easy to disassemble, assemble, and transport. Background Technology

[0002] A lathe is a machine tool primarily used to machine rotating workpieces using a cutting tool. Drills, reamers, taps, dies, and knurling tools can also be used on a lathe for various machining operations. Lathes are mainly used for machining shafts, discs, sleeves, and other workpieces with rotating surfaces. The core component of a lathe is the boring mechanism. Currently, the boring mechanisms of modern lathes are fixed in the workshop after leaving the factory, making them inconvenient to disassemble and transport when the lathe needs to be moved to another workshop or sold.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] As shown in the figure, this utility model discloses a boring mechanism that is easy to disassemble, assemble, and transport. It includes a main motor 1, a main unit 2, a main boring bar 3, and a boring bar 4. The main unit 2 includes a main unit housing 5. The main motor 1 is mounted on the outside of the main unit housing 5. A main shaft 6 is mounted on the inside of the main unit housing 5 via bearings. The main boring bar 3 is mounted on the inside of the main shaft 6. The boring bar 4 is mounted at the end of the main boring bar 3. A driven wheel 7 is mounted on the main shaft 6. A driving wheel 8 is mounted on the output end of the main motor 1. The driving wheel 8 and the driven wheel 7 are connected by a belt 9. A shaft is mounted on the inside of the main boring bar 3. A sleeve 11 is installed on the top of the axial transmission rod 10, and the sleeve 11 is connected to the lead screw nut 12. The lead screw nut 12 is connected to the lead screw 13. The top of the main boring bar 3 is installed on the axial slide plate 14, and the lead screw bracket 15 and the motor 16 are installed on the axial slide plate 14. One end of the lead screw 13 is installed on the lead screw bracket 15 through a bearing, and the driven wheel 17 is installed at the end of the lead screw 13. The output end of the motor 16 is equipped with the driving wheel 18, and a belt is provided between the driving wheel 18 and the driven wheel 17. This utility model improves the structure. The boring bar 4 is installed at the end of the main boring bar 3. During operation, both the main boring bar 3 and the boring bar 4 are located inside the workpiece 31, and the main boring bar 3 can extend, retract, and rotate.

[0022] This invention also includes an axial transmission rod 10. For smaller workpieces, a smaller boring bar 4 can be installed on the axial transmission rod 10, and machining can still be achieved. This invention has a wide range of applications. The axial transmission rod 10 can only move horizontally relative to the main boring bar 3. The main boring bar 3 can drive the axial transmission rod 10 to rotate (this is a conventional technology; alternatively, a groove could be provided on the axial transmission rod 10, and a key could be installed on the main boring bar 3, but this will not be described in detail here). This invention facilitates transport and circulation.

[0023] In one embodiment of this utility model, the axial sliding plate 14 has three protrusions, two of which are fitted with sliding sleeves 19, and one protrusion is fitted with a lead screw nut 20. A sliding rod 21 is installed at the sliding sleeve, and a lead screw 22 is installed at the lead screw nut 20. Two main sleeves 23 and one main sleeve 24 are installed on the main housing 5. One end of the sliding rod is located at the main sleeve 23, and one end of the lead screw 2 is located at the sleeve 24. The other ends of the two sliding rods and the lead screw 2 are located at the connecting plate 25. The tail of the lead screw 2 is connected to a motor 26. The motor 26 can also drive the axial sliding plate 14 to move horizontally, thereby driving the main boring bar 3 to move horizontally.

[0024] In one embodiment of this utility model, a protective cover 27 is provided on the outer side of the slide rod 21 and the lead screw 22. The protective cover 27 is installed between the main housing 5 and the connecting plate 25. A connecting block 28 is installed at the axial slide plate 14. The protective cover 27 is provided with a clearance groove 271, through which the connecting block 28 passes. The protective cover 27 serves a protective function. The connecting block 28 can also be a sensing block, used to sense the position of the axial slide plate 14, thereby indirectly determining the position of the bottom of the main boring bar 3.

[0025] In one embodiment of this utility model, the bottom of the main housing 5 is provided with an outer ring 51, and the outer ring 51 is provided with a plurality of circumferentially distributed adjustment seats 29. The adjustment seats 29 can be finely adjusted to ensure that the boring bar 4 is coaxial with the workpiece 31.
