It is widely used in the field of mechanical processing and has many advantages.

[0003] When performing different processing techniques, the cutter head of a Swiss-type lathe usually needs to be replaced. Existing Swiss-type lathe cutter heads are usually installed and fixed with bolts. During the replacement process, the operator needs to use auxiliary tools to disassemble and install them, which is relatively cumbersome and easily affected by the tool holder or other structures, resulting in limited operating space, affecting installation accuracy, and reducing work efficiency and processing quality. In view of this, the present application proposes a quick-install mechanism for the cutter head of a Swiss-type lathe. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0026] The utility model provides a technical solution: Figure 1-4 As shown, a quick-install mechanism for a Swiss-type machine tool head includes a power head 1, a plug-in shaft 11 is installed on the top of the power head 1, a power gear 12 is fixedly installed on the upper end of the plug-in shaft 11, a mounting cavity 13 is opened inside the power head 1, a mounting seat 2 is provided at the bottom of the power head 1, a tool 3 is installed on the mounting seat 2, and a tool 3 is provided at one end of the tool 3 extending into the mounting cavity 13. The tool handle 31 extends into the fixture 5, and the end of the tool handle 31 away from the tool 3 is set as a wedge block, and the size of the wedge block corresponds to the size of the inclined wedge surface 62. Further, with reference to Figure 3 The side walls of the wedge block on the handle 31 are both inclined surfaces, which can contact the inclined wedge surfaces 62 on both sides of the movable block 6 respectively, and can push the movable block 6 to move with less effort, avoiding obstacles when connecting the handle 31.

[0027] like Figure 5As shown, an adjusting mechanism 4 is provided inside the mounting cavity 13, and the adjusting mechanism 4 includes a piston 41, a spring 42 is provided on one side of the piston 41, and a baffle 43 is provided on the other side of the piston 41. A connecting rod 44 is fixedly connected to the side wall of the piston 41, and the end of the connecting rod 44 away from the piston 41 is fixedly connected to the side wall of the clamp 5. The diameter of the piston 41 is equal to the diameter of the mounting cavity 13, and the baffle 43 is set to a circular ring shape, and the baffle 43 is fixedly connected to the inner wall of the mounting cavity 13, one end of the spring 42 is fixedly connected to the side wall of the piston 41, and the other end of the spring 42 is fixedly connected to the inner wall of the mounting cavity 13. It should be noted that after the clamping is completed, the pressure change on one side of the piston 41 and the elastic force of the spring 42 can make the side wall of the piston 41 resist against the side wall of the baffle 43, thereby maintaining the stability of the piston 41 and avoiding the movement of the clamp 5 during operation to cause the tool 3 to jump, thereby ensuring the processing and forming quality of the parts.

[0028] like Figure 6 and Figure 7 As shown, a clamp 5 is provided on one side of the adjustment mechanism 4, and the clamp 5 cooperates with the mounting seat 2 to realize the rapid disassembly of the tool 3. A plurality of through slots 51 are opened circumferentially on the clamp 5, and limiting slots 52 are opened on both sides of the plurality of through slots 51 respectively. A movable block 6 is jointly provided in the plurality of through slots 51 and the limiting slots 52. The limiting blocks 61 are fixedly connected to the two sides of the top of the movable block 6 respectively, and the position of the limiting block 61 corresponds to the position of the limiting slot 52. The end of the movable block 6 extending into the clamp 5 is symmetrically provided with an inclined wedge surface 62, and a card slot 63 is opened at the bottom of the movable block 6.

[0029] It should be noted that the clamp 5 is arranged in the raised portion in the mounting cavity 13 (eg Figure 2 and Figure 3 As shown in the figure, a matching groove is provided on one side of the raised portion close to the opening of the clamp 5, which can be used for the movement of the movable block 6, and the limit of the knife handle 31 can be released more flexibly. Furthermore, one end of the clamp 5 drives the movable block 6 into the matching groove, and the knife handle 31 can be directly removed. At this time, the limiting blocks 61 set on both sides of the top of the movable block 6 are in contact with the side walls of the limiting groove 52, which can limit one end of the movable block 6 to the clamp 5, preventing the movable block 6 from falling into the clamp 5 and affecting the connection of the knife handle 31.

[0030] In addition, a circulation hole 14 is provided on the other side of the adjustment mechanism 4, and the circulation hole 14 is connected to a hose 7. The other end of the hose 7 extends to the outside of the power head 1. Furthermore, the hose 7 is connected to an external vacuum device. Through the opened circulation hole 14, one end of the installation cavity 13 and the piston 41 form a closed space. The air pressure on one side of the piston 41 can be adjusted by the external vacuum setting, and the piston 41 can be driven to move by the pressure change.

[0031] The present invention provides a quick-loading mechanism for the cutter head of a Swiss-type lathe, and the specific working principle is as follows: when the cutter head needs to be replaced, the external vacuum equipment connected to the hose 7 is started to pump air to one side of the piston 41. Since the edge of the piston 41 is in close contact with the inner wall of the installation cavity 13, the internal pressure of the installation cavity 13 changes, thereby pushing the piston 41 to move, and at the same time driving the spring 42 on the other side of the piston 41 to contract, and the connecting rod 44 fixedly connected to the piston 41 drives the clamp 5 to move synchronously, and finally drives the tool handle 31 to enter the matching groove formed on the other side of the clamp 5. At this time, the tool handle 31 can be pulled outward, and the wedge block set on the top of the tool handle 31 contacts the inclined wedge surface 62, thereby pushing the movable block 6 out of the through groove 51, and at the same time releasing the fixation of the tool handle 31 by multiple movable blocks 6, so that the tool 3 can be directly removed from the mounting seat 2.

[0032] When replacing the tool 3, the fixture 5 is still in the matching groove. The tool handle 31 is inserted into the fixture 5. The wedge block on the tool handle 31 contacts the inclined wedge surface 62 on the other side, pushing the top of the movable block 6 out of the fixture 5. The external vacuum equipment is controlled to evacuate one side of the piston 41 to reduce the pressure on one side of the piston 41. With the elastic force of the spring 42, the piston 41 will move, and the fixture 5 is driven to move synchronously through the connecting rod 44, so that the side wall of the piston 41 contacts the side wall of the baffle 43 to determine the installation position. The top of the movable block 6 is against the inner wall of the raised part in the installation cavity 13 (refer to Figure 2 ), finally, the bottom of the movable block 6 abuts against the side wall of the tool handle 31, fixing the tool handle 31 and completing the installation of the tool 3.

[0033] 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.
