Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a multi-station tailstock adjustment structure for machine tools. Background Technology

[0002] Currently, multi-station tailstock structures are widely used in CNC machine tool machining to improve machining efficiency and automation levels. Traditional tailstock structures mostly use hydraulic or pneumatic drives to move and position the tool, which has problems such as complex structure, slow response speed, low positioning accuracy, and high maintenance costs. Especially when multiple tools work together, the synchronization and stability between stations are difficult to guarantee, affecting the overall machining quality and efficiency.

[0003] In existing technologies, some machine tools use lead screws or linear guides to achieve linear movement of the tool, but these still suffer from problems such as insufficient transmission rigidity, susceptibility to load effects, poor protection performance, and limited service life. Furthermore, traditional structures often lack effective buffering and protection mechanisms for movement in the Y-axis direction, leading to vibration and impact during high-speed reciprocating motion, further affecting machining accuracy and equipment lifespan.

[0004] Therefore, a multi-station tailstock adjustment structure for machine tools is proposed to solve the problem of high-precision tailstock adjustment structure with stable transmission, good protection, and suitability for independent multi-station coordination, so as to meet the processing requirements of modern CNC machine tools for high efficiency, high precision and high reliability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The multi-station tailstock adjustment structure of the machine tool in this embodiment includes a machine cover 1 and an electrical control box 2. The electrical control box 2 is located at the top of the back of the machine cover 1, and the electrical control box 2 and the machine cover 1 are integrally formed and separated by a sheet metal partition. The front of the machine cover 1 is provided with an electrical control cabinet door 4, and a touch screen display 3 is also provided on one side of the front of the machine cover 1. An alarm light 5 is provided at one corner of the top of the machine cover 1.

[0024] Inside the housing 1 is a base 8, and the top of the base 8 is an arched beam 7. The arched beam 7 has three sets of tool magazine slides 9. Each of the three tool magazine slides 9 is equipped with a tool loading container 19. Each of the three tool loading containers 19 has several tools 18 on its top. Each of the three tool magazine slides 9 has an adjustment structure inside that drives the tool loading container 19 on its top to move back and forth along the Y-axis.

[0025] The housing 1 is an integral shell structure, with an electrical control box 2 integrally formed on its top back, electrically isolated from the housing by a sheet metal partition. The front of the housing 1 features an electrical control cabinet door 4 and a touchscreen display 3, with an alarm light 5 at one corner for status display and abnormal warning. Inside the housing 1, a base 8 is fixedly installed to support the entire tailstock structure. An arched crossbeam 7 is mounted on top of the base 8, with three sets of tool magazine slides 9 arranged parallel to each other on this crossbeam.

[0026] In this embodiment, each tool magazine slide 9 is equipped with an independent Y-axis adjustment structure to drive the tool loading container 19 on top of it to move back and forth. The core of this adjustment structure includes a motor 13, a worktable 11, a drive shaft 15, and two slide rods 14. The motor 13 is fixedly installed inside the tool magazine slide 9, and its output end is connected to the drive shaft 15 through a coupling to transmit power to the worktable 11. The two slide rods 14 are horizontally fixed on both sides inside the tool magazine slide 9, serving as precision guide tracks for the sliding of the worktable 11 to ensure the straightness and stability of the movement process.

[0027] In this embodiment, the worktable 11, in cooperation with the slide rod 14 via a linear bearing, can slide precisely along the Y-axis under the drive of the motor 13. Both the worktable 11 and the tool magazine slide 9 adopt an arched structure and are arranged intersectingly, with the worktable 11 located below the arched plate of the tool magazine slide 9. A connecting plate is bolted to the top of the worktable 11 for mounting the tool loading container 19. A strip-shaped through hole is opened in the middle of the connecting plate, through which the arched plate of the tool magazine slide 9 passes, maintaining a small gap between the two to ensure structural strength while preventing interference with each other's movement.

[0028] To protect the internal transmission components and prevent the intrusion of chips and coolant, Y-axis telescopic guards 16 are installed at both the front and rear ends of the worktable 11. These guards employ an accordion-style structure, extending and retracting with the movement of the worktable 11, providing excellent sealing and cushioning. Furthermore, two sets of cable chains 17 are installed inside the tool magazine slide 9 to organize and protect the air pipes, oil pipes, and cables connected to the worktable 11.

[0029] In this embodiment, a water tank 6 is located at the rear of the machine cover 1 to collect coolant and chips. Two discharge ports are located on the back of the machine cover 1, with their discharge ends facing the top of the water tank 6, facilitating direct discharge of waste materials into the water tank. An X-axis control structure 10 is located directly in front of the arched crossbeam 7. This structure typically consists of a servo motor, a lead screw, and a linear guide rail, used to control the synchronous or independent movement of the three machine head covers 12 in the X-axis direction, enabling multi-station processing.

[0030] The working principle of the above embodiments is as follows:

[0031] When the system receives the processing instruction, the controller in the electrical control box 2 controls the corresponding motor 13 to start according to the program, and drives the worktable 11 to move along the slide bar 14 in the Y-axis direction through the transmission shaft 15, thereby driving the tool loading container 19 and the tool 18 to the preset processing position.

[0032] Throughout the movement, the Y-axis telescopic shield 16 effectively protects the internal mechanisms, and the cable chain 17 ensures the safe movement of the cables. The X-axis control structure 10 can coordinate with the movement of the head cover 12 to achieve precise positioning of the tool in the XY plane, completing multi-station, high-efficiency machining tasks.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
