Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a multi-functional power head quick-change device for combination machine tools. Background Technology

[0002] A multi-functional power head for modular machine tools is a key power component that integrates multiple functions, providing the main motion and feed motion for the machine tool. It can perform various machining functions such as drilling, boring, milling, and tapping. By changing different tools and accessories, it can adapt to the machining requirements of different types of parts and complete complex machining processes. It typically consists of a main motion component, a feed motion component, and a control system. The main motion component is generally driven by a three-phase asynchronous motor, which transmits the motor's torque to the spindle via a synchronous toothed belt and splined shaft. Different spindle speeds can be achieved by changing different synchronous toothed belt pulleys. The feed motion component often uses compressed air or hydraulic pressure as a power source to achieve the spindle's "rapid feed—working feed—" cycle. The automatic cycle of "fast return" is provided, and the feed speed and feed stroke are continuously adjustable. The control system consists of various valves, sensors, and controllers, which are used to realize the motion control, speed regulation, and position control of the power head to ensure the accuracy and stability of the machining process. At the same time, the power head is small in size, light in weight, and compact in structure, which can effectively save machine tool space and is easy to install and maintain. It has a wide range of applications and can be combined in various ways. It can be combined into various forms of combination machine tools according to user needs, which improves the versatility and flexibility of the machine tool. Its spindle speed can also be flexibly adjusted according to machining requirements, further ensuring machining efficiency and accuracy. While multi-functional power heads for combination machine tools offer comprehensive features, they suffer from significant shortcomings in rapid tool changeover. Their structural design involves relatively fixed connections between the main motion components and the feed motion components, requiring high precision in the fit between each component. Replacement necessitates the disassembly and reassembly of multiple components, including the synchronous toothed pulley and tool accessories. Furthermore, adjusting the transmission parameters corresponding to different machining functions requires additional calibration steps. Coupled with the tight linkage logic between the control system and the overall machine tool, the replacement process necessitates re-adjusting the matching parameters of sensors, valves, and other control components. This results in a lengthy and cumbersome replacement process, hindering rapid switching of tools and functional modules. In scenarios requiring frequent changes in machining operations, this significantly impacts production efficiency and increases downtime and adjustment costs. Summary of the Invention

[0016] Reference Figures 1 to 4In this embodiment of the present invention, a multi-functional power head quick-change device for a combination machine tool includes: a back plate 1 and a power head 13. A top plate 2 is fixedly connected to the top of the back plate 1. A pressing block 3 is movably connected inside the top plate 2. Four sets of guide strips 16 are vertically arranged around the side of the pressing block 3, and the guide strips 16 are adapted to the vertical guide groove inside the top plate 2. Their function is to ensure that the pressing block 3 maintains stable vertical movement in subsequent operations. Side plates 4 are fixedly connected to both sides of the top plate 2. A return spring sleeve 5 is hinged between the two sets of side plates 4 and the two sides of the pressing block 3. A locking hook plate 6 is rotatably connected below the side plate 4. A connecting post 7 is fixedly connected to the inner side of the locking hook plate 6. The side of the connecting post 7 is hinged to one end of a movable plate 8, and the other end of the movable plate 8 is hinged to the bottom hinge block of the pressing block 3. The side plate 4, the return spring sleeve 5, the locking hook plate 6, the connecting post 7, and the movable plate 8 are all present. Two sets of locking hook plates are provided, and the locking hook plates 6 are adapted to the top plate of the power head 13. When the power head 13 is installed, the locking hook plates 6 will be locked to the top plate of the power head 13 by the elastic force of the return spring sleeve 5 through the transmission of the connecting column 7 and the movable plate 8, thus achieving the initial fixation of the power head 13. When the power head 13 needs to be replaced, press down on the pressing block 3. The pressing block 3 will drive the other end of the movable plate 8 to move down through the bottom hinge block. One end of the movable plate 8 will pull the locking hook plates 6 to rotate around the rotation axis of the side plate 4 through the connecting column 7, so that the locking hook plates 6 are released from the lock of the top plate of the power head 13. At this time, the return spring sleeve 5 is stretched and stored. After replacing the new power head 13, release the pressing block 3. The elastic force of the return spring sleeve 5 will drive the locking hook plates 6 to reset and relock the top plate of the power head 13. A front plate 9 is fixed to the front side of the top plate 2. A lead screw 10 is hinged to the side of the front plate 9. A knob 11 is fixed to one end of the lead screw 10, and a stop block 12 is fixed to the other end of the lead screw 10. As a further embodiment of this utility model, the stop block 12 is attached to one side of the power head 13. After the power head 13 is initially fixed, rotating the knob 11 can drive the lead screw 10 to rotate, so that the stop block 12 at the end of the lead screw 10 moves toward the side of the power head 13 and fits tightly, further enhancing the stability of the installation of the power head 13. When replacing the power head 13, rotating the knob 11 in the opposite direction can cause the lead screw 10 to move the stop block 12 away from the power head 13, releasing the lateral fixation of the power head 13, making it easier to remove the old power head 13. Then, rotating the knob 11 in the forward direction can make the stop block 12 fit against the side of the new power head 13 again to complete the fixation. The bottom of the power head 13 is equipped with a cutting head 14 for normal processing operations. An acrylic plate 15 is installed on the outside of the power head 13 to protect the outside of the power head 13. A mounting rail 17 is installed on the upper part of the back of the back plate 1. When installing the power head 13, the entire device is first fixed in a suitable position by the mounting rail 17.

[0017] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0018] The working principle of this utility model is as follows: When installing the power head 13, the entire device is first fixed in a suitable position by the mounting guide rail 17 at the upper end of the back of the back plate 1. Then, the power head 13 is placed in the designated installation position. At this time, the locking hook plate 6, under the elastic force of the return spring sleeve 5, is initially fixed by locking the top plate of the power head 13 through the transmission of the connecting column 7 and the movable plate 8. Then, the knob 11 is rotated to drive the lead screw 10 to rotate, so that the abutment block 12 at the end of the lead screw 10 moves towards the side of the power head 13 and fits tightly to enhance the installation stability. When it is necessary to replace the power head 13, the knob 11 is rotated in the opposite direction to drive the lead screw 10 to move the abutment block 12 away from the power head 13 to release the lateral fixation. Then, the pressing block 3 is pressed down. The pressing block 3 is located inside the four sets of guide strips 16 and the top plate 2. With the cooperation of the vertical guide groove, it maintains vertical and stable movement. At the same time, the bottom hinge block drives the other end of the movable plate 8 to move down. One end of the movable plate 8 pulls the locking hook plate 6 around the rotation axis of the side plate 4 through the connecting column 7, so that the locking hook plate 6 is released from the lock on the top plate of the power head 13. At this time, the return spring sleeve 5 is stretched and stored. After the old power head 13 is removed, the new power head 13 is placed in place. The pressing block 3 is released, and the elastic force of the return spring sleeve 5 drives the locking hook plate 6 to reset and relock the top plate of the power head 13. Finally, the knob 11 is rotated in the forward direction so that the abutment 12 is attached to one side of the new power head 13 to complete the fixation. Throughout the process, the acrylic plate 15 on the outside of the power head 13 plays a protective role. The cutting head 14 at the bottom can be used for normal processing after installation.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
