Description

Technical Field

[0001] This application relates to the field of machine tool processing technology, specifically to a flexible adjustable turning and milling composite machine tool. Background Technology

[0002] In the field of modern high-precision machining, mill-turning machines are widely used in the precision manufacturing of complex parts because they can perform multiple machining operations such as turning, milling, drilling, and boring in one integrated manner. Among these, the flexibility of tool adjustment directly affects the machining capability and accuracy of the machine tool and is one of the important indicators for evaluating the performance of mill-turning machines.

[0003] Currently, most milling and turning machines use a single-degree-of-freedom electric adjustment method to adjust the tool position. While this traditional method is simple in structure and low in cost, it has several shortcomings in practical applications. Although single-degree-of-freedom electric adjustment improves automation, it often only allows movement in one direction, making it difficult to meet the multi-angle, multi-directional machining needs of complex curved surfaces or irregularly shaped workpieces. Furthermore, existing adjustment mechanisms lack good guiding and support structures during movement, making them prone to inaccurate tool positioning due to vibration or misalignment, thus affecting machining quality. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a flexible and adjustable turning and milling composite machine tool, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a flexible adjustable turning and milling composite machine tool, including a vertical support, a supporting arch frame provided on the upper surface of the vertical support, a drive motor provided on the supporting arch frame, a bracket mounting plate connected to the moving end of the drive motor, guide support plates symmetrically provided on both sides of the bracket mounting plate, a tool holder support provided between the guide support plates, a lateral motor arch frame provided on one side of the guide support plate at the right end, a lateral drive motor provided on one side of the lateral motor arch frame, an adapter shaft connected to the output end of the lateral drive motor, the adapter shaft connected to the tool holder support, a mounting bracket provided at one end of the tool holder support, and a workpiece placement seat provided at the lower end of the vertical support.

[0006] As a preferred technical solution of this application, a vertical support plate is provided between the vertical supports, and a guide shaft seat is provided on the side of the vertical support plate. The sliding block in the guide shaft seat is connected to the bracket mounting plate by fasteners.

[0007] As a preferred technical solution of this application, the guide shaft seat includes a positioning seat, a vertical guide shaft and a sliding block. The positioning seats are symmetrically arranged on the side of the vertical support plate, and the vertical guide shaft is located between the positioning seats. The sliding block is slidably arranged on the vertical guide shaft.

[0008] As a preferred technical solution of this application, a through hole is provided in the middle of the tool holder support, and an adjustment motor is coaxially arranged in the through hole. The output end of the adjustment motor is connected to a mounting bracket.

[0009] As a preferred technical solution of this application, the tool holder support has a concave structure.

[0010] As a preferred technical solution of this application, the workpiece placement seat includes a longitudinal support and a transverse support, the transverse support is provided on the longitudinal support, and a placement plate is provided on the movable end of the transverse support.

[0011] As a preferred technical solution of this application, both the longitudinal support and the transverse support adopt a screw mechanism and a slide rail mechanism, the slide rail mechanism is arranged on both sides of the screw mechanism, and an intermediate support plate is provided at the upper end of the longitudinal support.

[0012] As a preferred technical solution of this application, the bottom of the vertical support is provided with a shock-absorbing pad, which is made of rubber or polyurethane material.

[0013] Compared with existing technologies, the beneficial effects of this application are as follows: This application, through the design of a multi-degree-of-freedom adjustment mechanism, significantly improves the flexibility and machining accuracy of tool adjustment, overcoming the shortcomings of existing single-degree-of-freedom adjustment mechanisms that cannot meet the high-precision machining requirements of complex curved surfaces and irregular contours. By setting up a drive motor, a lateral drive motor, and an adjustment motor, the tool can be independently adjusted in the vertical, forward / backward, and left / right directions, forming a multi-degree-of-freedom adjustment system in three-dimensional space. Compared with traditional single-degree-of-freedom adjustment methods, this structure can meet the needs of diverse machining paths such as complex curved surfaces, inclined surfaces, and arcs, greatly improving the applicability and machining flexibility of the machine tool. The bracket mounting plate slides in conjunction with the vertical guide shaft through a sliding block, achieving high guiding accuracy and effectively preventing offset and shaking during movement. The adjustment motor drives the mounting bracket to rotate, ensuring the accuracy of tool angle adjustment, thereby comprehensively improving the positioning accuracy and repeatability of the tool system.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example 1, please refer to Figure 1-2 A flexible adjustable turning and milling compound machine tool includes a vertical support 6, a support arch 2 on the upper surface of the vertical support 6, a drive motor 1 on the support arch 2, the output end of the support arch 2 connected to the drive motor 1, a bracket mounting plate 4 connected to the moving end of the drive motor 1, guide support plates 11 symmetrically arranged on both sides of the bracket mounting plate 4, a tool holder support 10 arranged between the guide support plates 11, a lateral motor arch 9 arranged on one side of the guide support plate 11 at the right end, a lateral drive motor 5 arranged on one side of the lateral motor arch 9, an adapter shaft connected to the output end of the lateral drive motor 5, the adapter shaft connected to the tool holder support 10, a mounting bracket 15 arranged at one end of the tool holder support 10, and a workpiece placement seat arranged at the lower end of the vertical support 6.

[0020] The workpiece placement seat includes a longitudinal support 8 and a transverse support 14. The transverse support 14 is provided on the longitudinal support 8, and a placement plate 7 is provided on the movable end of the transverse support 14.

[0021] Both the longitudinal support 8 and the transverse support 14 adopt a screw mechanism and a slide rail mechanism. The slide rail mechanism is set on both sides of the screw mechanism. The upper end of the longitudinal support 8 is provided with a middle support plate, and the longitudinal support is set on the upper surface of the middle support plate.

[0022] By using the longitudinal support 8 and the transverse support 14, the position of the workpiece can be flexibly adjusted. Combined with the adjustment of the cutting tool, the machining accuracy and machining flexibility can be effectively improved.

[0023] Mounting bracket 15 is used to place the cutting tool for machining the workpiece, providing a mounting position for the cutting tool.

[0024] A vertical support plate is provided between the vertical supports 6, and a guide shaft seat is provided on the side of the vertical support plate. The sliding block in the guide shaft seat is connected to the bracket mounting plate 4 by fasteners.

[0025] The vertical support plate not only provides a mounting base for the guide shaft seat, but also the side wings on both sides of the vertical support plate are connected to the vertical support 6 by fasteners, which further improves the support strength of the device.

[0026] The guide shaft seat includes a positioning seat 13, a vertical guide shaft 12, and a sliding block. The positioning seat 13 is symmetrically arranged on the side of the vertical support plate, and the vertical guide shaft 12 is located between the positioning seats 13. The sliding block is slidably arranged on the vertical guide shaft 12.

[0027] When the drive motor 1 moves the bracket mounting plate 4 up and down, the sliding block slides along the vertical guide shaft 12, ensuring the vertical movement accuracy of the bracket mounting plate 4. The guiding effect of the sliding block effectively prevents the bracket mounting plate 4 from shifting or shaking during movement, thereby improving the machining accuracy of the tool.

[0028] The bottom of the vertical support 6 is provided with a shock-absorbing pad, which is made of rubber or polyurethane material.

[0029] In this embodiment, the drive motor 1 drives the bracket mounting plate 4 to rise and fall. During the rising and falling process, the height of the mounting bracket 15 is adjusted, thereby adjusting the height of the tool. When it is necessary to adjust the front and rear angle, the lateral drive motor 5 is driven to further meet the processing requirements.

[0030] Example 2, please refer to Figure 1 , Figure 2 and Figure 3 A flexible adjustable turning and milling composite machine tool is further optimized in embodiment 1. A through hole is provided in the middle position of the tool post support 10. An adjustment motor 3 is coaxially arranged in the through hole. The output end of the adjustment motor 3 is connected to the mounting bracket 15.

[0031] This mechanism allows for rotational adjustment of the mounting bracket 15 in the left and right directions. Compared to Embodiment 1, this embodiment adds an additional degree of freedom for tool adjustment, further improving the tool's flexibility. In use, when machining is required in the left and right directions, after meeting the position requirements in Embodiment 1, the adjustment motor 3 is activated to adjust the mounting bracket 15 in the left and right directions, thereby adjusting the angle of the tool to meet the machining requirements.

[0032] Furthermore, the tool holder support 10 has a concave structure.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
