Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting technology for tool changing mechanisms, specifically a casting for a machining center tool changing mechanism that is easy to adjust. Background Technology
[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then grinding.
[0003] For example, patent document CN 211991980 U discloses a tool changing mechanism for machining centers that facilitates quick tool replacement. It includes a cylinder and a clamping disc. The cylinder's output flange is connected to a pneumatic rod, and a connecting rod is provided at the top of the pneumatic rod. A base is welded to the top side wall of the connecting rod, and a seat is provided on the inner side of the base. A slide rail is provided on the outer edge of the outer wall of the seat. The clamping disc is welded to one outer wall of the base. This invention, through the cooperation between the slide rail and the pulley, increases the lubrication of the base's vertical movement, preventing jamming during lifting. Furthermore, during the vertical sliding of the base driven by the pneumatic rod, it avoids uneven loading due to space limitations. Within a certain range, the cylinder can maintain normal operation. Simultaneously, the same cylinder ensures smooth tool changing for heavy tools, preventing the tool holder from tilting upwards after installation.
[0004] However, in actual use, due to its own structural limitations, this structure can only perform simple switching and limiting operations on the tool changing mechanism casting of the machining center. After switching, the tool changing mechanism casting as a whole cannot obtain stable limiting protection, which easily leads to abnormal vibration during subsequent machining. At the same time, the equipment cannot perform stable connection limiting operations after switching, which cannot meet the daily use needs. Therefore, it is urgent to design a machining center tool changing mechanism casting that is easy to adjust to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an easily adjustable machining center tool changing mechanism casting to solve the problem mentioned in the background art. In actual use, due to the limitations of its own structure, the existing structure of the machining center tool changing mechanism casting can only perform simple switching and limiting operations. After switching, the tool changing mechanism casting cannot obtain stable limiting protection, which easily leads to abnormal shaking during subsequent processing. At the same time, the equipment cannot perform stable connection limiting operations after switching, which cannot meet the daily use needs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a casting of a tool changing mechanism for a machining center that is easy to adjust, including a mounting shaft seat, a drive motor being provided at one end of the mounting shaft seat, a tool changing assembly being sleeved on the outer surface of the mounting shaft seat, and a locking assembly being provided at one end of the mounting shaft seat;
[0007] The tool changing assembly includes a switching sleeve, and the outer surface of the switching sleeve is fitted with the switching sleeve.
[0008] The locking assembly includes a locking sleeve, and the other end of the mounting shaft is provided with a locking sleeve, and one end of the locking sleeve is provided with a hydraulic push rod.
[0009] Preferably, the locking sleeve is provided with an elastic rubber ring at one edge near the mounting shaft seat, and a top connecting ring seat is provided at one end of the elastic rubber ring.
[0010] Preferably, the locking sleeve is internally fixedly connected to a positioning inner liner, and the inner wall of the positioning inner liner is provided with positioning slots on all four sides.
[0011] Preferably, a locking seat is fixedly connected to all four sides of the locking sleeve, and a locking block is fixedly connected to one end of the locking seat.
[0012] Preferably, a mounting tool holder is fixedly connected to the side of the switching bushing, and a mounting screw hole is provided at one end of the mounting tool holder.
[0013] Preferably, one end of the switching bushing is fixedly connected to a positioning socket, and the four sides of the positioning socket are fixedly connected to positioning clips.
[0014] Preferably, the switching bushing and the locking sleeve are adapted to each other.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This easily adjustable machining center tool changing mechanism casting, through its mounting bearings, drive motor, switching sleeve, locking sleeve, hydraulic push rod, locking seat, locking block, tool holder, and mounting screw holes, allows the equipment to perform more suitable switching and limiting operations on the tool changing mechanism casting. In actual use, the operator first installs four sets of tools of different specifications on the four sides of the switching sleeve at the tool holders and mounting screw holes. Then, the drive motor is started directly, causing it to rotate the entire switching sleeve on the outer surface at the mounting bearing, thus realizing the switching operation of the four sets of casting tools. After switching, the hydraulic push rod at one end of the locking sleeve can be activated, so that it fits and abuts at one end of the mounting bearing. The locking seats and locking blocks on the four sides of the locking sleeve can fit and lock onto the tool holders on the four sides of the switching sleeve, thus locking the tool changing mechanism and demonstrating the practicality of the equipment design.
[0017] This easily adjustable machining center tool changing mechanism casting, through its installation bearing, switching bushing, locking sleeve, elastic rubber ring, top connecting ring seat, positioning inner liner, positioning slot, positioning socket, and positioning clips, further enhances the overall usability of the equipment. During daily use, the operator can install the positioning socket at one end of the rotating switching bushing. When the locking sleeve is fitted onto the other end of the installation bearing, the positioning clips on the four sides of the positioning socket can perform a matching limiting docking operation with the positioning inner liner and positioning slot on the inner wall of the locking sleeve, thereby further improving the limiting and locking effect after tool changing. Simultaneously, when the locking sleeve is docked to the other end of the installation bearing, it can work with the elastic rubber ring and top connecting ring seat at one end for a tight fit, preventing subsequent external interference and demonstrating the comprehensiveness of the equipment design.

A tool changing assembly is fitted onto the outer surface of the mounting base 1. A locking assembly is installed at one end of the mounting base 1. The tool changing assembly includes a switching sleeve 3. A tool holder 12 is fitted onto the outer surface of the switching sleeve 3. A mounting screw hole 13 is provided at one end of the tool holder 12. A positioning socket 14 is fixedly connected to one end of the switching sleeve 3. Positioning clips 15 are fixedly connected to the four sides of the positioning socket 14. The switching sleeve 3 and the locking sleeve 4 are compatible. When the drive motor 2 is started, it rotates the entire switching sleeve 3 fitted onto the outer surface at the mounting base 1 for adjustment, thereby realizing the switching operation of four sets of casting tools.
[0027] The locking assembly includes a locking sleeve 4. The other end of the mounting shaft seat 1 is provided with a locking sleeve 4. One end of the locking sleeve 4 is provided with a hydraulic push rod 5. An elastic rubber ring 6 is provided on the edge of the locking sleeve 4 near the mounting shaft seat 1. One end of the elastic rubber ring 6 is provided with a top contact ring seat 7. The locking sleeve 4 is fixedly connected to a positioning inner liner 8. The four sides of the inner wall of the positioning inner liner 8 are provided with positioning slots 9. The four sides of the side of the locking sleeve 4 are fixedly connected with locking seats 10. One end of the locking seat 10 is fixedly connected with a locking block 11. When the locking sleeve 4 is fitted onto the other end of the mounting shaft seat 1, the positioning strips 15 on the four sides of the positioning socket 14 can perform a matching and limiting docking operation with the positioning inner liner 8 and the positioning slots 9 on the inner wall of the locking sleeve 4, thereby further improving the limiting and locking effect after tool change.
[0028] Working principle: In use, the operator first installs four sets of tools of different specifications on the four sides of the switching sleeve 3, at the tool holders 12 and the mounting screw holes 13. Then, the operator directly starts the drive motor 2, which rotates the entire switching sleeve 3 on the outer surface at the mounting seat 1 to achieve the switching operation of the four sets of casting tools. After switching, the hydraulic push rod 5 at one end of the locking sleeve 4 is activated, so that it fits and pushes against one end of the mounting seat 1. The locking seats 10 and locking blocks 11 on the four sides of the locking sleeve 4 fit into the tool holders 12 on the four sides of the switching sleeve 3 to lock the tool changing mechanism. In daily use, the operator can install the positioning socket 14 at one end of the rotating switching sleeve 3. Then, when the locking sleeve 4 is fitted onto the other end of the mounting shaft 1, the positioning strips 15 on the four sides of the positioning socket 14 can perform a matching limiting docking operation with the positioning inner liner 8 and positioning slot 9 on the inner wall of the locking sleeve 4, thereby further improving the limiting locking effect after tool change. At the same time, when the locking sleeve 4 is docked to the other end of the mounting shaft 1, it can cooperate with the elastic rubber ring 6 and the top connecting ring seat 7 at one end to achieve a tight fit at the connection point, avoiding subsequent external influences. The above is the complete working principle of this utility model.
