Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a power head for a turning-milling composite machine tool. Background Technology

[0002] In the field of modern machine tool processing technology, especially in the application of mill-turning composite machine tools, the power head is a key component for realizing multiple processing functions. As a component that directly executes cutting and other processing actions, the performance and function of the power head have a fundamental impact on the processing capability and processing quality of the entire mill-turning composite machine tool.

[0003] Traditional power head installation methods often rely on bolts and other connectors for fastening. During the installation process, operators need to accurately align the bolt holes and tighten multiple bolts. This process is not only cumbersome and time-consuming, but also requires a high level of skill from the operators. If the bolts are not tightened evenly, it may affect the installation accuracy of the power head, which in turn will have an adverse effect on the machining accuracy of the milling and turning machine tool. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a power head for a turning and milling composite machine tool.

[0005] This utility model is achieved using the following technical solution: a power head for a milling and turning composite machine tool, including a mounting base. The upper surface of the mounting base is provided with a positioning groove. A first return spring is fixedly connected to both sides of the inner wall of the positioning groove. A washer is fixedly connected to the upper surface of the first return spring. An assembly seat is provided on the upper surface of the washer. The power head body is fixedly connected to the upper surface of the assembly seat. Telescopic spring buckles are provided on both sides of the assembly seat. An embedding groove is provided on both sides of the inner wall of the positioning groove.

[0006] The above technical solution uses a pressure pad under the mounting base to compress the return spring, and a telescopic snap-fit ​​is inserted into the embedded circular groove to achieve installation. When disassembling, simply remove the telescopic snap-fit ​​from the embedded circular groove, and the first return spring will automatically pop out the mounting base and the power head body, which improves the efficiency of power head replacement and reduces the time cost of equipment maintenance.

[0007] As a further improvement to the above solution, the embedded circular groove is adapted to the telescopic snap fastener, and the telescopic snap fastener is disposed inside the embedded circular groove.

[0008] Through the above technical solution, the embedded circular groove is adapted to the telescopic spring buckle and the telescopic spring buckle is set inside the embedded circular groove, which ensures that the mounting base and the power head body can be stably connected to the mounting base during installation, preventing loosening or displacement during machine tool operation, and ensuring the stability and machining accuracy of the turning and milling composite machine tool.

[0009] As a further improvement to the above solution, spring grooves are provided on both sides of the mounting base, and a second return spring is fixedly connected to the inner wall of the spring groove.

[0010] The above technical solution involves setting spring grooves on both sides of the mounting base, connecting the second return spring to the telescopic snap-fit, so that the telescopic snap-fit ​​can retract into the spring groove when subjected to pressure from the wall of the embedded circular groove. This design ensures that the telescopic snap-fit ​​can smoothly enter the embedded circular groove for installation, and also provides some room for telescopic movement when encountering slight installation deviations or vibrations during operation, preventing damage from excessive compression, thus improving the adaptability and durability of the power head structure.

[0011] As a further improvement to the above solution, a blocking ring is fixedly connected to the inner wall of the embedded circular groove, and a pressing rod is provided inside the blocking ring.

[0012] Through the above technical solution, the blocking ring can play a certain limiting role in the pressing rod, preventing the pressing rod from excessive displacement or falling out of the embedded groove when subjected to external force.

[0013] As a further improvement to the above solution, a pressing block is fixedly connected to one end of the pressing rod.

[0014] As a further improvement to the above solution, the compression block comes into contact with the surface of the telescopic spring buckle.

[0015] As a further improvement to the above solution, the blocking ring, pressing rod and squeezing block are all disposed inside the embedded circular groove.

[0016] With the above technical solution, the blocking ring, the pressing rod and the squeezing block are all set inside the embedded circular groove, and the volume of the blocking ring is larger than that of the squeezing block. This design ensures that the squeezing block can apply sufficient pressure to the telescopic snap fastener to achieve disassembly, while also preventing the squeezing block from driving the pressing rod out of the embedded circular groove when subjected to external force.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes the cooperation between a telescopic spring buckle and an embedded circular groove. During installation, simply pressing it down to the appropriate position will automatically engage it, eliminating the need for complex bolt tightening operations and significantly saving installation time and manpower. The design of components such as the pressing rod and the squeezing block allows the telescopic spring buckle to easily disengage from the embedded circular groove during disassembly. The power head is then ejected by the resetting action of the first return spring. Because the blocking ring is larger than the squeezing block, the squeezing block is blocked when it reaches the surface of the blocking ring, preventing the squeezing block from being affected by external forces and causing the pressing rod to disengage from the embedded circular groove. This facilitates quick and easy replacement and disassembly of the power head, contributing to improved equipment maintenance efficiency. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4 This embodiment of a turning-milling composite machine tool power head includes a mounting base 1. A positioning groove 2 is formed on the upper surface of the mounting base 1. First return springs 3 are fixedly connected to both sides of the inner wall of the positioning groove 2. A washer 4 is fixedly connected to the upper surface of the first return spring 3. An assembly seat 5 is provided on the upper surface of the washer 4. A power head body 6 is fixedly connected to the upper surface of the assembly seat 5. Telescopic spring clips 7 are provided on both sides of the assembly seat 5. Embedding grooves 8 are formed on both sides of the inner wall of the positioning groove 2. When the power head body 6 is installed, the assembly seat 5 presses down on the washer 4, compressing the first return spring 3, and the assembly seat 5 enters the positioning groove 2. When the assembly seat 5 is pressed down to a certain position, the telescopic spring clips 7 engage with the embedding grooves 8, completing the installation connection between the assembly seat 5, the power head body 6, and the mounting base 1. During disassembly, the telescopic spring clips 7 disengage from the embedding grooves 8, the first return spring 3 returns to its original position, causing the washer 4 to rise, ejecting the assembly seat 5 and the power head body 6, enabling quick replacement.

[0028] The embedded circular groove 8 is adapted to the telescopic spring buckle 7. The telescopic spring buckle 7 is set inside the embedded circular groove 8. The embedded circular groove 8 and the telescopic spring buckle 7 are adapted to each other, and the telescopic spring buckle 7 can be set inside the embedded circular groove 8. This ensures that the telescopic spring buckle 7 can be accurately locked into the embedded circular groove 8 during installation, ensuring the stability of the installation; and it can also be easily disassembled from the embedded circular groove 8 during disassembly.

[0029] Spring grooves 9 are provided on both sides of the mounting base 5. A second return spring 10 is fixedly connected to the inner wall of the spring groove 9. The second return spring 10 is fixedly connected to the surface of the telescopic snap 7. When the telescopic snap 7 is subjected to the pressure of the hole wall, it can retract into the interior of the spring groove 9 through the second return spring 10. At this time, the second return spring 10 is compressed and stores elastic potential energy.

[0030] A blocking ring 11 is fixedly connected to the inner wall of the embedded circular groove 8. A pressing rod 12 is provided inside the blocking ring 11. When the pressing rod 12 is moved by force, it can drive the squeezing block 13 to move. The squeezing block 13 is used to apply pressure to the telescopic snap 7, so that it is disengaged from the embedded circular groove 8, thereby realizing the disassembly of the power head.

[0031] One end of the pressing rod 12 is fixedly connected to the pressing block 13. When the pressing block 13 moves, it can directly exert a pressing effect on the telescopic spring buckle 7, causing the telescopic spring buckle 7 to move and disengage from the embedded round groove 8, thereby achieving the purpose of disassembling the power head.

[0032] The compression block 13 contacts the surface of the telescopic spring buckle 7.

[0033] The blocking ring 11, pressing rod 12, and squeezing block 13 are all disposed inside the embedded circular groove 8. When disassembling the power head, the operator applies force to the pressing rod 12, causing the squeezing block 13 to move inward and squeeze the telescopic spring buckle 7 to disengage it from the embedded circular groove 8. The blocking ring 11 is larger than the squeezing block 13, preventing the squeezing block 13 from being affected by external force and causing the pressing rod 12 to disengage from the embedded circular groove 8. When the squeezing block 13 moves to the surface of the blocking ring 11, it is blocked, ensuring that the pressing rod 12 and the squeezing block 13 do not disengage from the embedded circular groove 8.

[0034] The implementation principle of the power head of a milling and turning composite machine tool in this application embodiment is as follows: The operator aligns the power head body 6 and the mounting base 5 together with the positioning groove 2 on the mounting base 1, and slowly presses down the power head body 6 and the mounting base 5. At this time, the mounting base 5 will press down the pad 4, and the pad 4 will compress the first return spring 3. The mounting base 5 gradually enters the positioning groove 2. The operator continues to press down until the mounting base 5 is pressed down to a certain position. The telescopic spring buckle 7 pops out under the action of the second return spring 10 and locks into the embedded groove 8. At this time, the mounting base 5 and the power head body are installed. The mounting body 6 is connected to the mounting base 1. When it is necessary to disassemble the power head, an external force is applied to the pressing rod 12, causing the pressing rod 12 to move into the embedded circular groove 8. The pressing rod 12 drives the squeezing block 13 to move. The squeezing block 13 applies pressure to the telescopic spring buckle 7. Under the pressure of the squeezing block 13, the telescopic spring buckle 7 overcomes the elastic force of the second return spring 10 and retracts into the spring groove 9, thereby disengaging from the embedded circular groove 8. The first return spring 3 resets, causing the pad 4 to rise, popping out the mounting base 5 and the power head body 6, thus realizing the disassembly of the power head.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
