Description

Technical Field

[0001] This utility model relates to the field of Swiss-type lathe technology, and in particular to a guide sleeve device for a Swiss-type lathe. Background Technology

[0002] A Swiss-type CNC lathe, also known as a headstock moving CNC lathe, is a high-precision, high-efficiency, and highly automated machine tool mainly used for machining small bar stock parts. During machining, the tool position is adjusted to remain fixed throughout the process. The machining is achieved by moving the spindle along the Z-axis and rotating the workpiece.

[0003] Patent document with application number 202322921335.4 uses multiple positioning screws in a circular array to clamp the workpiece, so as to achieve a good centering effect on workpieces of different diameters and avoid workpiece vibration during processing, which would cause damage to the workpiece.

[0004] However, in the above solution, each positioning screw needs to be turned individually to move it closer to or further away from the workpiece in order to clamp or release it, making the operation somewhat cumbersome. Furthermore, if the movement of the positioning screws is not synchronized when clamping the workpiece, the workpiece centering effect may be unsatisfactory. Utility Model Content

[0037] The embodiments of this utility model will be described in detail below.

[0038] Example

[0039] See Figures 1-3 This embodiment provides a guide sleeve device for a Swiss-type machine, including a bracket 1, a sleeve 2, a guide sleeve 3, a sliding sleeve 4, an adjusting ring 5, a clamp 6, and a connecting assembly 7.

[0040] The bracket 1 has a through hole.

[0041] The outer wall of the sleeve 2 is rotatably connected to the inner wall of the through hole, and the inner side of the sleeve 2 has several (e.g., six) guide grooves 21.

[0042] The guide sleeve 3 is sleeved with the sleeve 2. One end of the guide sleeve 3 is located outside the sleeve 2, and the other end has a positioning part 31 located inside the sleeve 2. The inner side of the positioning part 31 is tapered. The outer wall of the guide sleeve 3 has a protrusion 32, which is slidably connected to the guide groove 21. Multiple strip grooves 33 extending along the length direction are formed on the side wall of the guide sleeve 3.

[0043] The sliding sleeve 4 is slidably sleeved on the outside of the guide sleeve 3, and the sliding sleeve 4 has an insertion hole 41. The outer wall of the sliding sleeve 4 has external threads.

[0044] The adjusting ring 5 is sleeved on the sliding sleeve 4 and has an internal thread that mates with the external thread. The adjusting ring 5 and the sliding sleeve 4 are threadedly connected.

[0045] The collet 6 is inserted into the insertion hole 41 and is movably arranged along the radial direction of the sliding sleeve 4; the collet 6 passes through the strip groove 33 and can slide along the strip groove 33. There are multiple collets 6 (such as three), and the multiple collets 6 are arranged at equal intervals along the circumference of the sliding sleeve 4.

[0046] The connecting component 7 is used to connect the clamp 6 and the adjusting ring 5.

[0047] When the adjusting ring 5 moves relative to the sliding sleeve 4, the connecting assembly 7 causes the chuck 6 to move radially along the sliding sleeve 4, allowing multiple chucks 6 to simultaneously move closer or further apart, thus facilitating the clamping or loosening of the workpiece passing through the guide sleeve 3 and ensuring a centering effect. Furthermore, similar to existing technologies, in the above solution, since the sliding sleeve 4 is slidably fitted on the outside of the guide sleeve 3, and the chuck 6 is inserted into the insertion hole 41 and can slide along the strip groove 33, when the workpiece position is axially adjusted during processing, the workpiece can drive the chuck 6 and the sliding sleeve 4 to move together (left and right), avoiding damage to the workpiece surface due to relative movement between the workpiece and the chuck 6.

[0048] The connecting assembly 7 includes a connecting block 71 and a connecting rod 72. One side of the connecting block 71 has a T-shaped portion 711, which is slidably connected to the adjusting ring 5. One end of the connecting rod 72 is hinged to the connecting block 71, and the other end is hinged to the clamp 6.

[0049] Tighten the adjusting ring 5 to move it to the left, which in turn drives each clamp 6 through each connecting rod 72 to clamp the workpiece; turn the adjusting ring 5 in the opposite direction to move it to the right, which in turn drives each clamp 6 through each connecting rod 72 to release the workpiece.

[0050] In summary, this embodiment has at least the following beneficial effects:

[0051] First, by setting up the sliding sleeve 4, adjusting ring 5 and connecting component 7, each chuck 6 can be moved simultaneously, simplifying the operation of clamping or loosening the workpiece and ensuring centering effect.

[0052] Second, when adjusting the position of the workpiece axially during the processing, the workpiece can move together with the chuck 6 and the sliding sleeve 4, avoiding damage to the surface of the workpiece due to relative movement between the workpiece and the chuck 6.

[0053] Third, the sliding connection between the protrusion 32 and the guide groove 21 ensures that the guide sleeve 3 can move along the axial direction of the sleeve 2 while the sleeve 2 can drive the guide sleeve 3 to rotate.

[0054] Fourth, the inner side of the positioning part 31 is tapered, and one end of the workpiece can abut against the inner side of the positioning part 31, so that the workpiece can be better centered.

[0055] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. For those skilled in the art, this utility model can have various modifications and variations. Without conflict, the embodiments and features described in this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
