Description

Technical Field

[0001] This utility model relates to the field of machine tool processing equipment technology, and in particular to a multi-station processing head that can be moved separately. Background Technology

[0002] The machining head is an important component of a CNC machine tool, responsible for performing specific machining operations. A machining head typically consists of two parts: an outer casing and an inner core. Several drill bits are mounted on the outer casing via bearings. The rotary input shafts of these drill bits have a "I"-shaped connector at their top ends, located within the inner core. A laser head is mounted on the front of the inner core, and several pre-drilled openings are located on the outer casing directly opposite the laser head's output end. The inner core contains an internal cavity, within which a rotary shaft is mounted via bearings. A first bevel gear is located at the end of the rotary shaft. An adapter shaft is connected to the cavity opening via bearings. One end of the adapter shaft has a second bevel gear that meshes with the first bevel gear, and the other end has a mating groove adapted to the connector.

[0003] Traditional multi-station machining centers typically employ a synchronous drive structure, with each station having a fixed stroke, making it impossible to independently adjust the position according to processing requirements. This results in poor processing flexibility and low efficiency. While some existing technologies utilize servo motor drives, these suffer from structural complexity and insufficient synchronization accuracy. Furthermore, the displacement detection modules in existing multi-station machining centers often have low integration, making it difficult to achieve real-time and accurate feedback.

[0004] To address the aforementioned problems, this invention proposes a multi-station machining head that can be moved independently. Through independent linear motor drive and modular displacement detection technology, it significantly improves machining efficiency and accuracy. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a multi-station machining head that can be moved independently, thereby more accurately resolving the problems of inconvenient adjustment and poor synchronization of traditional machining heads through independent drive and high-precision detection technology.

[0025] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0026] Please refer to Figures 1-5 This utility model proposes a multi-station machining head that can be moved separately, including a base 1. A first slider assembly 2 is provided at the bottom of one side of the outer wall of the base 1, and a second slider assembly 3 is provided at the top of the first slider assembly 2 on one side of the outer wall of the base 1. A transverse drive assembly 4 is provided between the first slider assembly 2 and the second slider assembly 3 on one side of the outer wall of the base 1, and a displacement detection module 6 is provided at the top of one side of the outer wall of the base 1. The first slider assembly 2, the second slider assembly 3 and the transverse drive assembly 4 are distributed sequentially from bottom to top on the outer wall of the base 1.

[0027] The first slider assembly 2 includes a first slide rail 21 and a first slider 22. The first slide rail 21 is fixedly connected to the outer wall of one side of the base 1 by screws, and the first slider 22 is arranged in an array on one side of the first slide rail 21 and is slidably connected to the outer wall of the first slide rail 21.

[0028] The second slider assembly 3 includes a second slide rail 31 and a second slider 32. The second slide rail 31 is fixedly connected to one side of the outer wall of the base 1 by screws, and the second slider 32 is distributed in an array on one side of the second slide rail 31 and is slidably connected to the outer wall of the second slide rail 31.

[0029] The transverse drive assembly 4 includes a linear motor guide rail 41 and a linear motor body 42. The linear motor guide rail 41 is fixedly connected to the outer wall of one side of the base 1 by screws, and the linear motor body 42 is evenly distributed on one side of the linear motor guide rail 41 and fixedly connected to the outer wall of the linear motor guide rail 41 by screws.

[0030] In this embodiment, each machining head 5 achieves independent lateral movement through the linear motor body 42, and with the high-precision displacement detection module 6 providing real-time feedback of position data, the machining trajectory is dynamically adjusted by the control system. This machining head has advantages such as modularity, high precision, and easy maintenance. Through independent linear motor drive and modular displacement detection technology, it significantly improves machining efficiency and accuracy, and is suitable for complex machining scenarios of multi-spindle machine tools.

[0031] Each machining head has 5 independent drives, which can perform different stroke tasks, improving machining flexibility. High-precision displacement detection and closed-loop control ensure machining accuracy. The modular design facilitates assembly and maintenance, enabling independent control and high-precision machining of multiple workstations.

[0032] The base 1 has an array of machining heads 5 arranged on one side of its outer wall. The first slider 22 and the second slider 32 are both fixedly connected to the outer wall of one side of the machining head 5. The piston rod of the linear motor body 42 is fixedly connected to the outer wall of the machining head 5. Multiple machining heads 5 are arranged laterally along the base 1. The linear motor body 42 serves as the drive device, employing a coreless linear motor to reduce inertia and independently control the lateral movement stroke of the machining head 5.

[0033] The displacement detection module 6 uses a grating ruler, and a displacement detection sensor is set on one side of the grating ruler. The displacement detection sensor is fixedly connected to the outer wall of the machining head 5 by screws. The displacement detection module 6 contains multiple independent detection modules, each corresponding to a different machining head 5. The displacement detection module 6 uses a grating ruler with an accuracy of ±0.01mm to monitor the position information of the machining head 5 in real time.

[0034] The base 1 has a lower limiting plate 7 fixedly connected to one side of its outer wall at the bottom of the first slider assembly 2 by screws, and the machining head 5 is slidably connected to the top outer wall of the lower limiting plate 7. The lower limiting plate 7 fits against the outer wall of the machining head 5 to support the machining head 5 and prevent it from swinging downwards.

[0035] Both ends of the first slide rail 21 and the second slide rail 31 are fixedly connected to limiting end heads 8 by screws. The limiting end heads 8 can limit the maximum lateral movement distance of the machining head 5.

[0036] When using this device, the base 1 is made of high-strength aluminum alloy casting. On one side of the base 1, a first slider assembly 2, a second slider assembly 3, a transverse drive assembly 4, and a displacement detection module 6 are respectively provided. The first slider 22, the second slider 32, the linear motor body 42, and the displacement detection sensor on the first slider assembly 2, the second slider assembly 3, the transverse drive assembly 4, and the displacement detection module 6 are all fixedly connected to the processing head 5. The processing head 5 is moved by the linear motor body 42.

[0037] Each linear motor main body 42 is equipped with a coreless linear motor, which is driven independently by the control system. The movement trajectory of each machine head unit is dynamically adjusted according to the detection data. The displacement detection module 6 uses a magnetic scale to feed back the position data to the control system in real time, realizing closed-loop control. During processing, each machine head moves independently according to the preset program to complete the synchronous processing of multiple workpieces.

[0038] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
