Technical Field
[0001] This utility model relates to the technical field of vertical machining centers, and in particular to a quick tool change structure for vertical machining centers. Background Technology
[0002] Vertical machining centers evolved from CNC milling machines. The biggest difference between them lies in their ability to automatically change cutting tools. By installing different types of tools in the tool magazine, the automatic tool changer can switch the tools on the spindle during a single setup, enabling various machining functions. They are characterized by high machining accuracy and high production efficiency. Therefore, vertical machining centers are widely used in the manufacturing industry.
[0003] The existing patent publication number CN209754723U, entitled "Multi-head Switching Vertical Machining Center", proposes that this utility model can quickly switch the cutting heads through a novel cutting head switching device, thereby improving the machining range and machining accuracy while reducing the time consumed, thus improving the machining efficiency.
[0004] However, in the process of using the tool changing structure for vertical machining centers disclosed in the above patent, since the tool protrudes from the outer ring of the rotating disk, when one tool is drilling or performing other machining operations on the workpiece, the two adjacent tools will touch the workpiece, affecting the drilling and other machining operations. Therefore, it is necessary to propose a quick tool changing structure for vertical machining centers to solve the above problems. Utility Model Content

Each slide groove extends through both sides of the rotating disk. A U-shaped frame is slidably mounted inside the slide groove. One end of each cutting tool is movably engaged inside the U-shaped frame. A fixing hole is provided inside the cutting tool. A bolt connects the U-shaped frame and the fixing hole, and a fixing nut is threaded onto the outer ring of the bolt. A through hole is provided at the end of the slide groove for the cutting tool to pass through. A spring is fixedly connected between the U-shaped frame and the end of the slide groove. A protrusion is fixedly mounted on the side of the U-shaped frame, protruding from the side of the rotating disk away from the second motor.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figures 1-6 The vertical machining center quick tool change structure shown includes a support base 1 and a second motor 5. An adjustment component is provided between the support base 1 and the second motor 5. A rotating disk 6 is fixedly provided on the side of the second motor 5. Several tools 11 are arranged in a ring and uniformly distributed inside the rotating disk 6 through an installation component. A pushing component is provided between the rotating disk 6 and the second motor 5.
[0027] The mounting components include a slide 7, which is formed inside the rotating disk 6. Several slides 7 are arranged in a circular, evenly distributed manner. The number of slides 7 is the same as the number of cutters 11. The slides 7 extend through both sides of the rotating disk 6. A U-shaped frame 10 is slidably mounted inside the slide 7, and the U-shaped frame 10 is adapted to the slide 7. Limiting grooves 9 are formed on both sides of the slide 7, and limiting blocks 17 are slidably mounted inside the limiting grooves 9. The limiting blocks 17 are fixedly connected to the U-shaped frame 10. One end of the cutter 11 is movably engaged inside the U-shaped frame 10. A fixing hole 12 is provided inside the cutter 11. A bolt 13 is connected between the U-shaped frame 10 and the fixing hole 12. A fixing nut 14 is threaded onto the outer ring of the bolt 13. A through hole 8 is provided at the end of the slide groove 7 for the cutter 11 to move through. A spring 15 is fixedly connected between the end of the U-shaped frame 10 and the end of the slide groove 7. A protrusion 16 is fixedly provided on the side of the U-shaped frame 10. The protrusion 16 protrudes from the side of the rotating disk 6 away from the second motor 5.
[0028] The pushing component includes a movable shaft 18 that rotates in the middle of the rotating disk 6. The output end of the second motor 5 is fixedly connected to the movable shaft 18. A cam 19 is fixedly provided on the outer ring of the movable shaft 18. The cam 19 and the side of the rotating disk 6 away from the second motor 5 are in contact with each other.
[0029] The adjustment component includes a first motor 2, which is fixedly mounted on the side of the support base 1. A second motor 5 has a rotating shaft 3 at one end away from the rotating disk 6. The second motor 5 and the rotating shaft 3 are fixedly connected by a connecting flange. The output end of the first motor 2 passes through the side of the support base 1 and is fixedly connected to a first gear 4. The rotating shaft 3 passes through the side of the support base 1 and is fixedly connected to a second gear. The first gear 4 and the second gear mesh with each other.
[0030] Specifically, in the initial state of use, the protrusion 16 and the end of the slide groove 7 are in contact. After the second motor 5 is started, it drives the movable shaft 18 and the cam 19 to rotate. The cam 19 pushes the protrusion 16 to move until the end of the cam 19 is in contact with the protrusion 16, so that the corresponding tool 11 protrudes from the outer ring of the rotating disk 6. At this time, the spring 15 is stretched, and the other tools 11 are retracted into the interior of the slide groove 7 under the tension of the spring 15. This will not hinder the tool 11 from drilling or processing the workpiece. This solves the problem that in the existing vertical machining center tool changing structure, when one tool 11 is drilling or processing the workpiece, the two adjacent tools 11 will touch the workpiece, affecting the drilling or processing of the workpiece.
[0031] When it is necessary to change the tool 11, start the first motor 2, drive the first gear 4 and the second gear to rotate, which in turn drives the rotating shaft 3, the second motor 5 and the rotating disk 6 to rotate, and rotate the required tool 11 to the lowest position. Then start the second motor 5. Similarly, the tool 11 is lengthened and protrudes from the outer ring of the rotating disk 6, so that it can perform drilling and other processing on the workpiece without being obstructed by other tools 11, thus improving the convenience of tool changing of the device.
[0032] When the tool 11 is damaged, unscrew the fixing nut 14, remove the bolt 13, and the tool 11 can be pulled out from the inside of the through hole 8. Replace it with a new tool 11 and install it in reverse, which improves the convenience of device maintenance.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
