Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a machine tool slide structure. Background Art

[0002] The slide is a crucial component of CNC machine tools. After a workpiece is mounted on the slide, it reciprocates along the guide rails, carrying the workpiece. Existing slide structures typically utilize a threaded rod connected to the slide. Rotation of the rod drives the slide. However, because the rod is exposed, iron filings can easily adhere to the rod during machining, entering the connection between the rod and the slide. This can cause the rod to become stuck with the slide during rotation, preventing the slide from moving and hindering machining. Utility Model Content

[0003] The utility model aims to solve the defect in the prior art that iron chips are easily stuck in the threaded connection, resulting in the inability of the slide to move, and proposes a machine tool slide structure.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A machine tool slide structure is designed, including a base, a threaded sleeve is rotatably connected to the base through a bearing, a threaded column is internally threaded on the threaded sleeve, a connecting rod is fixedly connected to the threaded column, a slide is fixedly connected to the connecting rod, the slide is supported by a supporting mechanism, a first limiting ring is fixedly connected to the threaded sleeve, the first limiting ring abuts against the connecting rod, and the threaded sleeve is driven by a driving mechanism.

[0006] Preferably, the driving mechanism includes a motor, which is mounted on the base, and the output shaft of the motor is fixedly connected to a rotating shaft, the rotating shaft is fixedly connected to a first gear, the first gear is meshed with a second gear, and the second gear is fixedly connected to the threaded sleeve.

[0007] Preferably, a protective box is fixedly connected to the base, the protective box cover is provided on the first gear and the second gear, the rotating shaft is rotatably connected to the protective box via a bearing, and the threaded sleeve is rotatably connected to the protective box via a bearing.

[0008] Preferably, the support mechanism includes a connecting ear fixedly connected to the base, a sliding rod is provided through the connecting ear, and the sliding rod is fixedly connected to the base.

[0009] Preferably, a cleaning unit is placed on the base, and the cleaning unit is connected to the base via a connecting mechanism.

[0010] Preferably, the connecting mechanism includes a connecting column, the connecting column is fixedly connected to the cleaning part, a second limiting ring is sleeved on the connecting column, and the second limiting ring is fixedly connected to the base.

[0011] Preferably, the threaded column is a reciprocating threaded column.

[0012] The utility model proposes a machine tool slide structure, which has the beneficial effect of: using a driving mechanism to drive the threaded sleeve to rotate, thereby adjusting the position of the threaded column in the threaded sleeve, driving the connecting rod to move, and thus driving the slide to move; since the threaded connection is not exposed, iron chips are avoided from entering, thereby preventing jamming and ensuring the movement of the slide.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1

[0019] Reference Figure 1-3A machine tool slide structure includes a base 1, a threaded sleeve 6 is rotatably connected to the base 1 through a bearing, a threaded column 12 is internally threaded on the threaded sleeve 6, a connecting rod 8 is fixedly connected to the threaded column 12, and a slide 2 is fixedly connected to the connecting rod 8. The slide 2 is supported by a supporting mechanism, and a first limiting ring 9 is fixedly connected to the threaded sleeve 6. The first limiting ring 9 seals the threaded sleeve 6 to prevent iron filings from entering. The first limiting ring 9 abuts against the connecting rod 8. The threaded sleeve 6 is driven by a driving mechanism, and the threaded sleeve 6 is driven by the driving mechanism to rotate, thereby adjusting the position of the threaded column 12 in the threaded sleeve 6, driving the connecting rod 8 to move, and thereby driving the slide 2 to move. Since the threaded connection is not exposed, iron filings are avoided from entering, thereby preventing jamming and ensuring the movement of the slide 2.

[0020] The supporting mechanism includes a connecting ear 15 fixedly connected to the base 1, and a slide rod 3 is provided through the connecting ear 15. The slide rod 3 is fixedly connected to the base 1. When the slide 2 moves, the connecting ear 15 will be driven to slide on the slide rod 3, thereby supporting and limiting the slide 2.

[0021] The driving mechanism includes a motor 5, which is installed on the base 1. The output shaft of the motor 5 is fixedly connected to a rotating shaft, and the rotating shaft is fixedly connected to a first gear 13. The first gear 13 is meshed with a second gear 14, and the second gear 14 is fixedly connected to the threaded sleeve 6. When the motor 5 rotates, the first gear 13 is driven to rotate, thereby driving the second gear 14 to rotate, causing the threaded sleeve 6 to rotate.

[0022] The threaded column 12 is a reciprocating threaded column. When resetting, the motor 5 does not need to be rotated forward or reversed due to the use of the reciprocating threaded column.

[0023] When moving, the motor 5 rotates, driving the first gear 13 to rotate, thereby driving the second gear 14 to rotate, causing the threaded sleeve 6 to rotate, adjusting the position of the threaded column 12 in the threaded sleeve 6, driving the connecting rod 8 to move, and thus driving the slide 2 to move.

[0024] Example 2

[0025] In Example 1, it is easy to cause iron chips to enter between the first gear 13 and the second gear 14 during processing, causing the gears to become stuck. Figure 1-3 As another preferred embodiment of the present invention, based on Example 1, a protective box 7 is fixedly connected to the base 1, and the protective box 7 is covered on the first gear 13 and the second gear 14. The rotating shaft is rotatably connected to the protective box 7 through a bearing, and the threaded sleeve 6 is rotatably connected to the protective box 7 through a bearing. The protective box 7 plays a protective role and prevents iron chips from entering between the two gears.

[0026] Example 3

[0027] Reference Figure 1-3 As another preferred embodiment of the present invention, on the basis of Example 2, a cleaning part 4 is placed on the base 1, and the cleaning part 4 is connected to the base 1 through a connecting mechanism. The connecting mechanism includes a connecting column 10, and the connecting column 10 is fixedly connected to the cleaning part 4. A second limiting ring 11 is sleeved on the connecting column 10, and the second limiting ring 11 is fixedly connected to the base 1. By pulling the connecting column 10, the cleaning part 4 is driven to move, thereby cleaning the iron filings on the base 1.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
