Description

Technical Field

[0001] This utility model relates to the field of iron pad processing technology, specifically to a special machine tool for processing turnout iron pads. Background Technology

[0002] A turnout is a track connection device that allows locomotives and rolling stock to switch from one track to another. It is also one of the weakest links in the track. The turnout pad is an important component of railway turnouts. Its function is to support and lock the rails on the upper part and connect to the lower turnout sleepers through turnout sleeper bolts. During processing, holes are drilled using a special machine tool.

[0003] However, existing machine tools suffer from poor longitudinal symmetry due to difficulties in datum positioning and clamping, which affects processing efficiency.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN209811757U discloses a hole-processing device for turnout pads, comprising a base, four support columns, a fixed clamping plate, a movable clamping plate, a positioning column, and a locking mechanism. The four support columns are fixed to the base and support the four corners of the turnout pad to be processed. The fixed clamping plate is fixed to the base and abuts against one side of the turnout pad to be processed. The movable clamping plate is parallel to the fixed clamping plate and can reciprocate towards the fixed clamping plate. The locking mechanism can lock the position of the movable clamping plate. At least two support plates extending towards the movable clamping plate are provided at the top of the fixed clamping plate. The side of the support plate facing the movable clamping plate abuts against the draft angle of the turnout pad to be processed. The bottom of the positioning column is fixed to the base. This device solves the problem of longitudinal symmetry deviation caused by difficulties in datum positioning and clamping, while improving production efficiency.

[0005] The aforementioned device uses the pad spring seat close to the rail groove surface as a positioning reference during use. However, the device uses a single station for processing, resulting in low processing efficiency and affecting the overall production progress. Utility Model Content

[0013] Furthermore, the outer surface of the support plate is provided with a drilling assembly, and the inner side of the support plate is provided with a limiting rod, which is located on the inner side of the machine tool body.

Detailed Implementation

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: a special processing machine tool for turnout iron pads, including a machine tool body 1, two sets of symmetrical track seats 2 are provided on the inner side of the machine tool body 1, two sets of symmetrical movable plates 3 are provided on the outer surface of the track seats 2, and sliding blocks 4 are provided on the bottom surface of the movable plates 3; a servo motor 15 is provided at the top of the machine tool body 1, and an auxiliary positioning processing mechanism is provided at the output end of the servo motor 15.

[0028] The machining mechanism enables precise positioning and efficient machining of turnout iron pads. The lead screw 16 in the machining mechanism rotates under the drive of the servo motor 15, causing the support plate 17 to move along a preset trajectory, thereby adjusting the position of the drilling assembly 18. The limiting rod 19 on the inner side of the support plate 17 cooperates with the corresponding structure on the inner side of the machine tool body 1, ensuring the stability and accuracy of the support plate 17's movement and avoiding offset during machining. The cooperative design of the track seat 2 and the movable plate 3 allows the movable plate 3 to slide along the track seat 2 in a specific direction, further expanding the working range of the machining mechanism. The sliding block 4 on the bottom surface of the movable plate 3 is connected to the transmission system composed of the lead screw 5 and the drive motor 6. Through the forward and reverse rotation of the drive motor 6, the sliding block 4 reciprocates on the lead screw 5, thereby driving the movable plate 3 and its clamping components. The device is positioned to accommodate the processing requirements of turnout iron pads of different sizes. Another transmission system, consisting of the fixed seat 7 at the top of the movable plate 3, the lead screw 8, and the linear motor 9, is responsible for controlling the precise movement of the moving block 10 on the lead screw 8. A hydraulic pump 12 is installed on the mounting seat 11 at the top of the moving block 10. The hydraulic pump 12 drives the clamping plate 14 to open and close through the telescopic rod 13, thereby achieving a stable clamping of the turnout iron pad. The machine tool body 1 adopts a dual-station design, and the two stations can simultaneously perform processing operations on different turnout iron pads. This effectively avoids the time wasted due to frequent workpiece changes during single-station processing, significantly improving the overall processing efficiency. The dual stations operate independently yet cooperate with each other, greatly enhancing the flexibility and capacity of the production line while ensuring processing quality. This is especially suitable for the large-scale, high-efficiency production needs of turnout iron pads.

[0029] Example 2: Based on Example 1, please refer to... Figure 2 - Figure 6 The fixed seat 7 is also disclosed, and its specific structure is as follows: a lead screw 5 is provided on the inner side of the sliding block 4, a drive motor 6 is provided at the connecting end of the lead screw 5, a positioning seat is provided at the end of the lead screw 5 away from the drive motor 6, the drive motor 6 is provided on the machine tool body 1, a fixed seat 7 is provided at the top of the movable plate 3, a lead screw 8 is provided on both sides of the fixed seat 7, a linear motor 9 is provided at the connecting end of the lead screw 8, a moving block 10 is provided on the outer surface of the lead screw 8, a mounting seat 11 is provided at the top of the moving block 10, and a hydraulic pump 12 is provided on the outer surface of the mounting seat 11.

[0030] Through the cooperation of the fixed seat 7, the lead screw 8, and the linear motor 9, by Figure 6It is understood that precise and stable movement control is provided for the moving block 10. The linear motor 9, as the power source, can quickly respond and drive the lead screw 8 to rotate, thereby driving the moving block 10 to move linearly along the lead screw 8. This design allows the moving block 10 to precisely adjust its position on the lead screw 8 according to the processing requirements, thereby driving the mounting base 11 and hydraulic pump 12 to move accordingly to meet the processing requirements of turnout iron pads of different sizes and shapes. The hydraulic pump 12 is connected to the clamping plate 14 through the telescopic rod 13, and can precisely control the opening and closing degree and clamping force of the clamping plate 14 according to the processing instructions, thereby achieving a stable clamping of the turnout iron pad. This design not only improves the safety and stability of the processing process, but also effectively avoids processing errors and scrap rates caused by insecure clamping. In addition, the dual-station design of the machine tool body 1 further improves the processing efficiency. The two stations can perform processing operations on different turnout iron pads simultaneously without interfering with each other. This parallel processing method significantly shortens the overall processing cycle.

[0031] Example 3: Based on Example 1, please refer to... Figure 3 - Figure 6 The clamping plate 14 is also disclosed, and its specific structure is as follows: a telescopic rod 13 is provided on the outer surface of the hydraulic pump 12, and a clamping plate 14 is provided on the outer surface of the telescopic rod 13. Two sets of clamping plates 14 are provided, and the two sets of clamping plates 14 are symmetrically designed. The machining mechanism includes a lead screw 16, which is provided at the output end of the servo motor 15. A support plate 17 is provided on the outer surface of the lead screw 16, and a drilling assembly 18 is provided on the outer surface of the support plate 17. A limit rod 19 is provided on the inner side of the support plate 17, and the limit rod 19 is provided on the inner side of the machine tool body 1.

[0032] Through the symmetrical design of the clamping plate 14, by Figure 4 It is understood that the clamping force can be applied evenly during the processing to ensure that the turnout iron pad plate remains stable during processing and will not shift or deform due to uneven force. The hydraulic pump 12 drives the telescopic rod 13 to extend and retract, thereby driving the clamping plate 14 to open and close. This design is not only responsive, but also has adjustable clamping force, which can adapt to the processing needs of turnout iron pad plates of different thicknesses and materials. The lead screw 16 in the processing mechanism, driven by the servo motor 15, can accurately control the moving distance and speed of the support plate 17. The drilling assembly 18 set on the support plate 17 is responsible for accurately drilling holes in the turnout iron pad plate. The setting of the limit rod 19 further ensures the stability and accuracy of the support plate 17 during the movement process and avoids processing errors caused by movement deviation.
