A dual-station horizontal CNC machining center

Abstract

This utility model discloses a dual-station horizontal CNC machining center, comprising: a machine tool body, a base unit, and a limiting component. The base unit is disposed on the top of the machine tool body. The limiting component includes a first limiting plate and a second limiting plate disposed on the top of the base unit. The top of the first limiting plate and the second limiting plate are provided with positioning parts, and the sides of the first limiting plate and the second limiting plate are interlocked with snap-fit ​​parts. This utility model provides a limiting component on the top of the base unit, wherein the first limiting plate and the second limiting plate together limit the sides of the workpiece. The snap-fit ​​parts on the sides of the first limiting plate and the second limiting plate, which can be interlocked and replaced, limit the side protrusions of the workpiece. Compared with directly slotting the sides of the limiting plate for limiting, this design avoids the situation where the entire limiting plate needs to be replaced after long-term wear of the directly slotted area. Moreover, the snap-fit ​​parts can be replaced separately, avoiding the material waste of replacing the entire limiting plate.

Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a dual-station horizontal CNC machining tool. Background Technology

[0002] In a dual-station horizontal CNC machining center, the positioning accuracy of the workpiece directly affects the machining efficiency and quality. Existing equipment has multiple limiting plates directly set on the side of the machining base. When the workpiece is placed, the protrusions on the side of the workpiece are interlocked with the grooves between the limiting plates, thereby limiting and positioning the workpiece relative to the machining base.

[0003] However, the existing limiting plate has a limiting groove on the side where the protrusion of the workpiece is inserted. Over a long period of time, it bears the friction and impact of the protrusion on the side of the workpiece. The groove is prone to deformation or wear, which affects the limiting and positioning of the workpiece. Moreover, the limiting plate that is partially damaged cannot be restored to its function through local repair. The entire limiting plate must be replaced, which results in a waste of steel for the limiting plate.

[0004] Therefore, how to achieve partial maintenance through replaceable limit structures and avoid waste of limit plate materials has become an urgent problem to be solved for dual-station machine tools. Utility Model Content

[0039] A dual-station horizontal CNC machining center includes: a machine body 1, a base unit 2, and a limiting assembly;

[0040] It should be noted that the base unit 2 is located on the top of the machine tool body 1. The base unit 2 is used to support and fix the workpiece to be processed, and the limiting component is used to limit the workpiece to be processed. The working principle of the overall machine tool body 1 and the base unit 2 is referenced to the BF-H6363 dual-station horizontal machining center.

[0041] Specifically, the limiting component includes a first limiting plate 3 and a second limiting plate 4 disposed on the top of the base unit 2. The top of the first limiting plate 3 and the second limiting plate 4 are provided with positioning parts, and the sides of the first limiting plate 3 and the second limiting plate 4 are each connected with a snap-fit ​​part 6 for limiting the insertion of the workpiece.

[0042] It should be noted that fixing bolts 5 are inserted and connected to the sides of the first limiting plate 3 and the second limiting plate 4. The fixing bolts 5 are used to insert and fix the base unit 2 to the first limiting plate 3 and the base unit 2 to the second limiting plate 4. Fixing holes 7 are opened on the sides of the first limiting plate 3 and the second limiting plate 4. The fixing holes 7 are used for bolts to insert and limit the processing parts.

[0043] Specifically, the first limiting plate 3 and the second limiting plate 4 have through holes for fixing bolts 5 to pass through on their sides, and the base unit 2 has threaded grooves for fixing bolts 5 to pass through on its sides. The fixing hole 7 is a reserved threaded hole for bolts to pass through and fix the first limiting plate 3, the second limiting plate 4 and the workpiece by threaded insertion. The workpiece and the base unit 2 are fixed by bolts.

[0044] Specifically, the snap-fit ​​part 6 includes: a snap-fit ​​strip 601, a snap-fit ​​groove 602, a connector, and a spring-loaded component;

[0045] It should be noted that the side of the snap-fit ​​strip 601 is inserted and connected to the side of the first limiting plate 3 and the second limiting plate 4, the snap-fit ​​groove 602 is opened on the side of the snap-fit ​​strip 601, the connector is disposed at the intersection of the snap-fit ​​strip 601 and the first limiting plate 3 and the second limiting plate 4, and the spring-loaded component is disposed on the opposite side of the connector and the first limiting plate 3 and the second limiting plate 4.

[0046] Specifically, the connector is used to fix the position of the snap-fit ​​strip 601, the spring is used to push out the snap-fit ​​strip 601, the snap-fit ​​groove 602 is set as a rectangular groove, the snap-fit ​​groove 602 is used for the insertion of the workpiece to be processed, the connector includes a fixing block 603 and a locking bolt 604, the snap-fit ​​strip 601 inserted on the side of the first limiting plate 3 and the second limiting plate 4 are only different in length, and the rest of the structure is the same;

[0047] It should be noted that the fixing block 603 is disposed on the side of the snap-fit ​​strip 601, and the side of the fixing block 603 is inserted and connected to the side of the first limiting plate 3 and the second limiting plate 4. The end of the locking bolt 604 is inserted and connected to the side of the fixing block 603. The multiple locking bolts 604 are divided into two groups. One group of locking bolts 604 is used to insert and fix the fixing block 603 and the first limiting plate 3, and the other group of locking bolts 604 is used to insert and fix the fixing block 603 and the second limiting plate 4.

[0048] Specifically, the fixing block 603 is welded and fixed to the snap-fit ​​strip 601. The sides of the first limiting plate 3 and the second limiting plate 4 are provided with grooves through which the fixing block 603 is inserted. The inner wall of the groove is provided with a threaded groove through which the locking bolt 604 is inserted, thereby fixing the position of the fixing block 603.

[0049] Example 2:

[0050] A spring-loaded component is used in the dual-station horizontal CNC machining center described in Example 1.

[0051] Specifically, the springback components include: a movable plate 605, a compression spring 606, and a compression rod 607;

[0052] It should be noted that the side of the movable plate 605 is interlocked with the side of the fixed block 603, the compression spring 606 is set on one side of the movable plate 605, and the pressing rod 607 is set on the other side of the movable plate 605. The pressing rod 607 is used to press against the first limiting plate 3 and the second limiting plate 4.

[0053] Specifically, the fixed block 603 has a groove on its side for the movable plate 605 to pass through. One end of the compression spring 606 is welded and fixed to the groove wall, and the other end of the compression spring 606 is welded and fixed to the movable plate 605. The movable plate 605 is welded and fixed to the pressing rod 607. The pressing rod 607 is pressed by the first limiting plate 3 and the second limiting plate 4, which causes the compression spring 606 to deform. This structure causes the fixed block 603 to be pushed, making the locking bolt 604 and the threaded groove more tightly engaged, preventing the locking bolt 604 from loosening. After the locking bolt 604 is removed, the compression spring 606 pushes the fixed block 603 out of the groove and out, making it easy for maintenance personnel to take it out.

[0054] In actual use, a limiting component is provided on the top of the base unit 2 of the machine tool body 1. The first limiting plate 3 and the second limiting plate 4 together limit the side of the workpiece. The snap-fit ​​part 6 on the side of the first limiting plate 3 and the second limiting plate 4 can be inserted and replaced to limit the side protrusion of the workpiece. Compared with the limiting plate directly slotting the side, this design avoids the situation that the limiting plate needs to be replaced as a whole after long-term wear of the directly slotted part. Moreover, the snap-fit ​​part 6 can be replaced separately, avoiding the material waste of replacing the entire limiting plate.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
