As one of the important tools in sheet metal processing, the chamfering machine is mainly used to remove burrs on the edges of materials and form a certain chamfer to improve the aesthetics and safety of products. Especially when processing precision parts such as gears, the quality of the chamfer directly affects the performance and service life of the final product. Therefore, how to efficiently and accurately complete the chamfering processing of gears has become a key link that cannot be ignored in the manufacturing process.

[0003] There are some deficiencies in the existing sheet metal processing chamfering machines when fixing gears.

Detailed Embodiment

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a sheet metal processing chamfering machine for facilitating the fixation of gears, including a machine base 1. A processing table 2 is provided on the top of the machine base 1. Above the processing table 2, a chamfering tool 3 is installed through a driving mechanism. The driving mechanism is mounted on a hydraulic lifting column installed on the processing table 2. The chamfering tool 3 can be lifted through the driving mechanism and various angle conversions can be carried out using a rotating base. A number of strip-shaped grooves 5 are provided around the top of the processing table 2. A pushing cylinder 6 is provided at the outer end of the strip-shaped groove 5. The outer end of the pushing cylinder 6 is fixed to the inner wall at the outer end of the strip-shaped groove 5 through a fixing block in cooperation with a bolt. The output ends of the pushing cylinders 6 all face the inner end of the strip-shaped groove 5. The output ends of the pushing cylinders 6 are welded and fixed with a limiting member 7 having a right-angle structure. Inside the vertical part of the limiting member 7, a round block 8 is rotatably connected through an opening. A number of different specifications of teeth 9 are welded and fixed around the edge of the round block 8. And outside the vertical part of the limiting member 7, a servo motor 10 for driving the round block 8 to rotate is fixedly installed through a support block. Above the servo motor 10, a scale sensor 11 is fixedly installed through screws. The scale sensor 11 adopts a linear displacement sensor of model LDT045. When this structure of chamfering machine is in use, the limiting member 7 can be moved along the strip-shaped groove 5 to the periphery of the gear through the telescopic action of the pushing cylinder 6, and the servo motor 10 is synchronously started. The servo motor 10 drives the round block 8 to rotate. The round block 8 meshes with the outer edge of the gear through the teeth 9 of the appropriate specification, realizing the stable fixation of gears of different specifications. At the same time, the scale sensor 11 monitors the position change of the limiting member 7 in real time and feeds the data back to the control circuit of the servo motor 10, ensuring that the rotation angle and position of the round block 8 are accurate and error-free, thereby ensuring the stability and accuracy of the gear during the processing, reducing the influence of human factors on the processing quality, solving the problems of complex operation, insecure fixation and poor adaptability of the manual clamping or simple mechanical fixing device of the sheet metal processing chamfering machine in the prior art, and further improving the versatility and flexibility of the equipment, significantly shortening the preparation time and production cycle, reducing the production cost, and improving the overall production efficiency. A rotating shaft connected to the inside of the vertical part of the limiting member 7 is fixedly inserted through the center of the round block 8. One end of this rotating shaft is connected to the inner wall on one side of the vertical part of the limiting member 7 through a bearing, and the output end of the servo motor 10 extends into the inside of the vertical part of the limiting member 7 and is connected to one end of the rotating shaft at the center of the round block 8. When the servo motor 10 of this structure is started, its output end drives the round block 8 to rotate inside the vertical part of the limiting member 7 through the rotating shaft until the teeth 9 of the appropriate specification are switched to mesh with the outer edge of the gear, realizing the stable fixation of gears of different specifications, ensuring the stability and accuracy of the gear during the processing. A guiding block 12 is provided at the bottom of the horizontal part of the limiting member 7. The guiding block 12 and the limiting member 7 are of an integral structure, and a transverse guiding groove 13 matching the structure of the guiding block 12 is provided on the bottom wall of the strip-shaped groove 5. With this structure, the telescopic action of the pushing cylinder 6 drives the limiting member 7 to move along the strip-shaped groove 5, and the guiding block 12 will slide in the transverse guiding groove 13 synchronously.Ensure that the limiting member 7 maintains a stable and precise positioning during movement, preventing the limiting member 7 from shifting or tilting during movement, so as to ensure that the limiting member 7 can accurately reach the predetermined position, and ensure that the engaging teeth 9 on the round block 8 can be precisely engaged with the outer edge of the gear. A positioning center post 4 is provided at the center of the top of the processing table 2, and the bottom end of the positioning center post 4 is connected to the center of the top of the processing table 2 through a threaded structure. The positioning center post 4 of this structure can provide an accurate positioning reference for the gear. When the gear is placed on the processing table 2, its central hole is sleeved on the positioning center post 4 to ensure that the position of the gear during processing is accurate and error-free. This not only improves the positioning accuracy of the gear, but also simplifies the clamping process of the gear, reduces the influence of human factors on positioning, and thus ensures the stability and consistency of chamfering processing. The scale sensor 11 is connected to the control circuit of the servo motor 10 through a signal line, and the detection heads of the scale sensor 11 all face one side of the positioning center post 4. The scale sensor 11 of this structure monitors the position change of the limiting member 7 relative to the positioning center post 4 in real time, transmits the detected data to the control circuit of the servo motor 10 through the signal line, and the control circuit adjusts the rotation angle and speed of the servo motor 10 according to these data. A total of four limiting members 7 are provided on the top of the processing table 2, and the limiting members 7 are evenly distributed in a surrounding shape on the top of the processing table 2. The four limiting members 7 of this structure move closer to the gear simultaneously from four directions through the synchronous action of the pushing cylinders 6, ensuring that the gear is evenly fixed on the processing table 2, that is, each round block 8 drives the engaging teeth 9 to be precisely engaged with the outer edge of the gear, forming a stable four-point fixation, effectively preventing the displacement and vibration of the gear during processing.,

[0019] Working principle: When using this sheet metal processing chamfering machine that is convenient for fixing gears, first place the gear to be processed on the processing table 2, and its central hole is sleeved on the positioning center post 4 to ensure that the position of the gear on the processing table 2 is accurate and error-free. Subsequently, the pushing cylinder 6 is started, and its output end drives the limiting member 7 to move closer to the gear along the strip-shaped groove 5. The guiding block 12 at the bottom of the horizontal part of the limiting member 7 slides in the transverse guiding groove 13. When the limiting member 7 reaches the predetermined position, the servo motor 10 is started, and its output end drives the round block 8 to rotate inside the vertical part of the limiting member 7 through the rotating shaft. The different specifications of the engaging teeth 9 on the round block 8 are engaged with the outer edge of the gear to achieve stable fixation of the gear. At the same time, the scale sensor 11 monitors the position change of the limiting member 7 relative to the positioning center post 4 in real time, transmits the detected data to the control circuit of the servo motor 10 through the signal line, and the control circuit adjusts the rotation angle and speed of the servo motor 10 according to these data to ensure that the rotation angle and position of the round block 8 are accurate and error-free. Finally, the chamfering tool 3 is lifted and lowered through the hydraulic lifting column installed on the processing table 2, and various angle conversions are carried out by using the rotating base to perform precise chamfering processing on the gear, thus completing a series of operations.

[0020] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
