Description

Technical Field

[0001] This invention relates to the field of milling machine processing equipment technology, and in particular to a tail shield grease groove processing equipment and system. Background Technology

[0002] In the machining of grease grooves and grouting grooves for tail shields, the large diameter and weight of the workpieces make it difficult for ordinary equipment to complete the milling process. Currently, the commonly used solution is to use a large floor-type boring and milling machine. Floor-type boring and milling machines do not have a movable worktable; the workpiece is fixed on a floor platform, making them suitable for machining large and heavy workpieces. The spindle head moves vertically on the column, which moves longitudinally and laterally on the bed, or only laterally. The spindle head contains a ram that extends and retracts with the milling spindle. Its cross-sectional shape can be rectangular, square, or polygonal, with rectangular being the most common. The ram is large and has high rigidity, supporting the spindle and mounting accessories, suitable for heavy-duty milling, expanding the process range and improving machining accuracy. The boring spindle is installed inside the milling spindle and can extend, retract, and feed independently. Larger floor-type boring and milling machines also have a high-speed spindle for drilling. The machine tool is equipped with accessories such as a platform, rotary table, rear column, faceplate, vertical milling head, and universal milling head. In practical use, milling usually involves a larger workload than boring, hence it is also called a floor-type milling and boring machine, which is mainly used in heavy machinery manufacturing plants.

[0003] Using large floor-type milling machines to machine the tail shield shell presents several problems: 1. It represents a waste of resources, resulting in significant operational costs. Furthermore, the investment in large floor-type milling machines is substantial, making them unaffordable for most manufacturers. 2. When machining the grease grooves on the shell, the large floor-type milling machine only feeds along the X and Z axes, neglecting the Y axis, which is a significant waste. These two points indicate substantial room for optimization and improvement in the existing machining method. Summary of the Invention

[0026] This invention proposes a tail shield grease tank processing equipment.

[0027] Reference Figures 1 to 4 In this preferred embodiment, a tail shield grease groove processing device includes a support frame, a Z-axis drive device, a spindle sliding module mounting base 7, an X-axis drive device 10, a spindle drive motor 12 (a servo drive motor), and a spindle 9.

[0028] The spindle 9 is used to mount the milling cutter. The spindle sliding module mounting base 7 is installed inside the support frame. The Z-axis drive device is connected to the spindle sliding module mounting base 7 to drive it to move up and down relative to the support frame.

[0029] The spindle 9 is fixedly connected to the output shaft of the spindle drive motor 12 (the spindle drive motor 12 drives the spindle 9 to rotate), and the X-axis drive device 10 is connected to the spindle drive motor 12 to drive it to move laterally (i.e., move in the X direction) relative to the spindle sliding module mounting base 7.

[0030] Furthermore, a first slide rail 8 is fixed to the top surface of the spindle sliding module mounting base 7, and a slider adapted to the first slide rail 8 is mounted on the bottom end of the spindle drive motor 12. Through the cooperation of the first slide rail 8 and the slider, the smooth movement of the spindle drive motor 12 is achieved.

[0031] In this embodiment, the Z-axis drive device includes a Z-axis drive motor 6 (a servo drive motor) fixed to the top of the support frame and a first lead screw 4 (two first lead screws 4) connected to the output shaft of the Z-axis drive motor 6. The first lead screw 4 is threadedly connected to the spindle sliding module mounting base 7 to drive it to move up and down.

[0032] In this embodiment, the support frame includes a foundation connecting seat 1 and a crossbeam 3 arranged opposite to each other, and two columns 2 connecting the two sides of the foundation connecting seat 1 and the crossbeam 3. That is to say, the support frame adopts a portal frame structure. The foundation connecting seat 1 is located at the bottom, and the Z-axis drive motor 6 is installed above the crossbeam 3. The foundation connecting seat 1 is connected to the foundation and serves to fix the entire device.

[0033] Furthermore, a ladder 14 is installed on the side of the column 2. The ladder 14 is for maintenance purposes. Because the support frame is quite high, the ladder 14 facilitates maintenance.

[0034] Furthermore, a second slide rail 5 is fixed on the column 2, and a groove (two grooves) is provided on the spindle sliding module mounting base 7 to accommodate the second slide rail 5. The second slide rail 5 is installed on both columns 2, thereby smoothly guiding the up and down movement of the spindle sliding module mounting base 7. Therefore, the Z-axis movement of the spindle sliding module mounting base 7 is smooth and reliable.

[0035] Furthermore, a second lead screw 11 is mounted on the first slide rail 8. The output shaft of the X-axis drive device 10 is connected to the second lead screw 11 to drive the main spindle drive motor 12 to move laterally relative to the main spindle sliding module mounting base 7. The second lead screw 11 is arranged parallel to the first slide rail 8. A lead screw nut is mounted on the main spindle drive motor 12; the lead screw nut and the slider are collectively referred to as the sliding module. The lead screw nut is fitted over the second lead screw 11. By rotating the second lead screw, the main spindle drive motor 12 is moved as a whole in the X-axis direction.

[0036] In this embodiment, the X-axis drive device 10 is a servo drive motor, and the motor mount of the servo drive motor is fixedly connected to the motor mount of the spindle drive motor 12.

[0037] Furthermore, an operating table 13 is fixed to the side of the support frame. The controller is mounted on the operating table 13 and is electrically connected to the Z-axis drive device, the X-axis drive device 10, and the spindle drive motor 12.

[0038] The working principle of the tail shield grease groove processing equipment is as follows: The workpiece is placed on the workpiece support and fixed by its own weight. Then, the workpiece is clamped back-to-back with the workpiece using two clamping blocks. Next, the milling cutter is installed on the spindle 9, and the path is pre-planned to determine the X-axis feed (groove depth), Z-axis feed (groove length), and processing position (indexing dimension). The spindle 9 speed and processing speed parameters are input into the controller, and the machine tool is started for processing. During processing, the first lead screw 4 drives the spindle sliding module mounting seat 7 to slide up and down relative to the second slide rail 5, completing the Z-axis feed. The second lead screw 11 drives the spindle 9 and motor to slide back and forth on the first slide rail 8 in the X-axis direction, completing the X-axis feed. The spindle 9, through rotation, drives the vertical milling cutter to rotate at high speed, thus completing the entire milling process (grease groove or grouting groove).

[0039] The tail shield grease groove machining equipment proposed in this embodiment is specifically designed for machining grooves of a given depth on the inner or outer surface of large-diameter semi-cylindrical or cylindrical shell structures, with significant advantages, particularly in machining grease grooves and grouting grooves for tunnel boring machines (TBMs). The equipment employs a lead screw and slide rail drive in the X and Z axes, coupled with a servo motor to precisely complete the tool feed in both directions. The grease groove is then milled by a 3-flute vertical milling cutter driven by a spindle 9. The entire feed and tool rotation process utilizes CNC technology, achieving high machining accuracy. The tail shield grease groove machining equipment proposed in this embodiment has the advantages of simple structure, ease of implementation, low manufacturing cost, and stable and reliable operation.

[0040] Compared to traditional floor-type boring and milling machines, this tail shield grease groove processing equipment eliminates unnecessary Y-axis feed in the process while meeting usage requirements. This simplifies and optimizes the existing equipment structure, significantly reducing the cost of grease groove processing and lowering equipment investment. It aligns with the trend towards green equipment development, further segmenting and personalizing the CNC machine tool industry, and driving its growth.

[0041] The present invention further proposes a tail shield grease groove processing system.

[0042] Reference Figures 1 to 4 In this preferred embodiment, a tail shield grease groove processing system includes the aforementioned tail shield grease groove processing equipment, and further includes a workpiece device backrest B and a workpiece support device C. The workpiece support device C is located below the workpiece to support its bottom, and the workpiece device backrest B has two clamping blocks to clamp the upper and lower ends of the workpiece respectively. The specific structure and beneficial effects of the tail shield grease groove processing equipment are as described in the above embodiment and will not be repeated here.

[0043] The tail shield grease groove processing system proposed in this invention designs the equipment clamping workbench as a support + clamping backrest, and its clamping method is stable and reliable.

[0044] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention.
