TECHNICAL FIELD

[0001] The present application relates to the technical field of railway frog processing equipment, in particular to an angle-adjustable processing platform for frog processing. BACKGROUND

[0002] In the current frog processing field, the angle adjustment mode of the processing platform is crucial to the processing efficiency and precision. At present, most frog processing adopts a gantry processing boring and milling machine with a manual universal accessory milling head, and the cutting of different angle processing features of the parts is realized through manual indexing positioning. This manual adjustment mode has many drawbacks. The operator needs to spend a lot of time and effort to manually adjust the angle of the milling head and position it, which is not only low in efficiency, but also difficult to ensure the accuracy of each angle adjustment due to the uncertainty of human operation, resulting in unstable control of processing precision and uneven product quality.

[0003] Therefore, it is necessary to provide an angle-adjustable processing platform for frog processing to solve the above technical problems. SUMMARY

[0004] The present application aims to provide an angle-adjustable processing platform for frog processing to solve the problems in the background art. The technical solution of the present application provides a solution significantly different from the prior art to solve the problem that the prior art solution is too single.

A gear that meshes with the toothed ring is rotatably connected inside the adjusting seat. A driving device for driving the gear to rotate is provided at one end of the adjusting seat.

[0009] Preferably, the clamping mechanism includes a hydraulic device two movably disposed on both the front and rear ends of the top of the base. A C-shaped plate is connected to the top of the hydraulic device two. A rectangular ring plate is installed on the top of the C-shaped plate.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0017] Please see Figures 1-4An adjustable machining platform for frog processing includes a base 1. A hydraulic device 2 is equidistantly mounted at the top center of the base 1. A support plate 3 is connected to the top of the hydraulic device 2. Adjustable seats 4, capable of synchronous or disjoint movement, are mounted on both sides of the top of the base 1. A circular plate 5 is mounted on the top of the adjustable seats 4. A limit component 6 is provided on the inner side of the circular plate 5. A clamping mechanism 7 is mounted at the front and rear ends of the top center of the base 1. The base 1 provides a stable support foundation. The hydraulic device 2 can flexibly adjust the height of the support plate 3 to adapt to the processing requirements of frogs of different thicknesses. The synchronous or disjoint movement design of the adjustable seats 4, combined with the circular plate 5 and the limit component 6, can adapt to the positioning of frog workpieces of different lengths and widths. The clamping mechanism 7 provides auxiliary fixation from the front and rear ends, forming an all-round fixing structure of "bottom support + side limit + front and rear clamping," effectively preventing workpiece displacement during processing, ensuring processing accuracy, and simultaneously supporting the processing of multi-specification frogs, thus improving the platform's versatility.

[0018] like Figures 1-4 As shown, the base 1 has a groove 8 at the front and rear ends of the top. A bidirectional screw 9 is rotatably connected inside the groove 8. The two ends of the outer wall of the bidirectional screw 9 are threadedly connected to threaded blocks 10 fixed to the bottom of the adjusting seat 4. Through the threaded engagement between the bidirectional screw 9 and the threaded blocks 10, the two adjusting seats 4 on both sides move synchronously in opposite directions, thereby adjusting the position between the two sets of adjusting seats 4.

[0019] like Figures 1-4 As shown, the limiting component 6 includes an annular groove 601 formed inside the annular plate 5. An arc-shaped block 603 is movably limited and installed at the upper and lower ends inside the annular groove 601. A connecting block 604 is connected to the arc-shaped block 603 facing the center of the annular plate 5. A fixing block 605 is installed at the other end of the connecting block 604. An adjusting rod 606 is threaded through the four corners of the fixing block 605 facing the inner wall of the annular plate 5. A pressure block 607 is connected to the end of the adjusting rod 606 facing the center of the annular plate 5. The annular groove 601 provides a stable movement trajectory for the arc-shaped block 603, ensuring that the arc-shaped block 603 drives the fixing block 605 to perform circumferential motion, adapting to the angle adjustment requirements of the frog's arc structure. The adjusting rods 606 at the four corners of the fixing block 605 can independently fine-tune the extension and retraction of the pressure block 607, which can accurately fit the irregular surface of the frog workpiece.

[0020] like Figures 1-4As shown, a connecting groove 11 is provided at the center of the outer side of the annular groove 601, and an arc-shaped through groove 12 is provided at the bottom of the connecting groove 11. A toothed ring 13 fixed to the outer side of the arc-shaped block 603 is movably arranged inside the connecting groove 11. A gear 14 that meshes with the toothed ring 13 is rotatably connected inside the adjusting seat 4. A driving device 15 is provided at one end of the adjusting seat 4 to drive the gear 14 to rotate. The driving device 15 drives the gear 14 to rotate, and the gear 14 meshes with the toothed ring 13 to drive the arc-shaped block 603 to rotate smoothly along the annular groove 601, thereby realizing the automatic adjustment of the angle of the limiting component 6, and thus adjusting the fixed angle of the fork.

[0021] like Figures 1-4 As shown, the clamping mechanism 7 includes a hydraulic device 701 movably mounted on both the front and rear ends of the top of the base 1. A C-shaped plate 702 is connected to the top of the hydraulic device 701. A rectangular ring plate 703 is mounted on the top of the C-shaped plate 702. An electric telescopic rod 704 is mounted on the inner top of the rectangular ring plate 703. The telescopic end of the electric telescopic rod 704 extends through the inside of the C-shaped plate 702 and is connected to a pressure plate 705. The hydraulic device 701 can adjust the height of the C-shaped plate 702 to accommodate forkworkpieces of different heights. The rectangular ring plate 703 provides a stable mounting base for the electric telescopic rod 704. The electric telescopic rod 704 drives the pressure plate 705 to move up and down, thereby clamping and fixing the workpiece vertically. The open structure of the C-shaped plate 702 facilitates the loading and unloading of the workpiece. The downward pressure of the pressure plate 705 can be precisely controlled by the electric telescopic rod 704 to avoid workpiece deformation due to excessive pressure.

[0022] like Figures 1-4 As shown, the top front and rear ends of the base 1 are provided with groove 2 16, and the two ends of the groove 2 16 are provided with slots 17. An electric telescopic plate 18 is installed inside the slots 17. The telescopic end of the electric telescopic plate 18 is connected to a movable block 19 fixed to the bottom of the hydraulic device 2 701. The electric telescopic plate 18 drives the hydraulic device 2 701 to move along the groove 2 16 and the slots 17 through the movable block 19, so as to realize the position adjustment of the clamping mechanism 7 in the front-back and left-right directions, adapt to the clamping requirements of fork workpieces of different lengths and widths, and expand the processing adaptation range of the platform.

[0023] like Figures 1-4 As shown, a rotating plate 20 is rotatably connected to the top of the middle support plate 3. The rotating plate 20 can rotate freely relative to the support plate 3. With the height adjustment of the hydraulic device 2 and the angle adjustment of the limiting component 6, multi-angle rotation positioning of the fork workpiece can be achieved.

[0024] Working Principle: During operation, the adjustable-angle machining platform for the frog uses base 1 as a stable support foundation. Through the coordinated operation of multiple mechanisms, it achieves precise positioning and angle adjustment of the frog workpiece. First, according to the length and width specifications of the frog, the double-direction screw 9 in groove 8 is driven to rotate. Utilizing the threaded engagement between the threaded block 10 and the double-direction screw 9, the adjusting seats 4 on both sides move synchronously towards or away from each other, so that the annular plate 5 adapts to the lateral dimensions of the workpiece. Simultaneously, the electric telescopic plate 18 in slot 17 drives the hydraulic device 701 to move along groove 16 via the movable block 19, adjusting the front-to-back and left-to-right positions of the clamping mechanism 7. In conjunction with the hydraulic device 701, the height of the C-shaped plate 702 is adjusted. The electric telescopic rod 704 pushes the pressure plate 705 to complete the vertical clamping and fixing of the front and rear ends of the workpiece. Subsequently, the hydraulic device 2... The drive support plate 3 is raised and lowered to a height suitable for the workpiece thickness. The rotating plate 20 can assist in adjusting the initial placement angle of the workpiece. If the workpiece processing angle needs to be adjusted, the drive device 15 on the adjustment seat 4 is started, which drives the gear 14 to rotate. Through the meshing transmission between the gear 14 and the gear ring 13, the arc block 603 is driven to move in a circular motion along the circular groove 601 of the circular ring plate 5. Then, through the connecting block 604 and the fixing block 605, the pressure block 607 is driven to rotate synchronously, realizing the automatic adjustment of the workpiece angle. During this period, the extension and retraction of the pressure block 607 can be independently finely adjusted by the adjustment rods 606 at the four corners of the fixing block 605 to ensure that the pressure block 607 accurately fits the irregular surface of the frog. Finally, an all-round fixing and multi-angle adjustment integrated operation mode of "bottom support + side limit + front and rear clamping" is formed to meet the angle requirements of different processing procedures of the frog.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
