Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to a milling flat part chamfering machine. Background Technology
[0002] In the field of machining, chamfering and milling are common basic process steps for metal materials such as stainless steel round bars. They are widely used in the manufacturing process of automotive parts, medical devices, precision instruments, and automated equipment. Chamfering is mainly used to cut the edges of workpieces into a certain bevel to improve assembly performance and safety. Milling, on the other hand, is to process one or more planar structures on cylindrical workpieces to meet the functional requirements of subsequent connection, positioning, or transmission.
[0003] Traditional processing methods typically employ multiple independent machines to complete different processes. For example, the end beveling is first completed using a chamfering machine, and then the workpiece is transferred to a milling machine or a dedicated milling flattening machine for flattening. This multi-machine, step-by-step processing method requires multiple machines and corresponding operators, resulting in large equipment investment, large floor space, and high production costs. In addition, the frequent handling and re-clamping of workpieces between different machines can easily cause positioning errors, affecting processing accuracy, and making it difficult to achieve continuous and automated production, thus limiting the improvement of overall production efficiency.
[0004] Therefore, there is an urgent need to provide an integrated milling and chamfering processing equipment to achieve automated operation of the entire process from material loading, clamping, positioning, chamfering, marking to milling. Summary of the Invention

Detailed Implementation
[0024] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0025] Example 1: Please refer to Figures 1-4A milling and chamfering machine for flat surfaces includes a worktable 1, a processing chamber 2 on the surface of the worktable 1, a first lifting cylinder 3 installed at the center of the worktable 1, a lifting platform 4 fixedly connected to the lifting rod of the first lifting cylinder 3, a loading rack 5 slidably connected to the lifting platform 4, the loading rack 5 being movable horizontally relative to the lifting platform 4, and a first electric push rod 6 installed on the loading rack 5, the movable rod of the first electric push rod 6 being connected to the lifting platform 4. Through the extension and retraction of the first electric push rod 6, the loading rack 5 can be driven to reciprocate linearly on the lifting platform 4, realizing the self-reciprocating motion of the workpiece. The loading rack 5 has a dynamic propulsion function. Six or more pneumatic clamps 7 are arranged at intervals along the length of the loading rack 5 on both sides to clamp and fix the stainless steel round bars, ensuring the stability of the workpiece during processing. Four or more limiting blocks 8 are arranged at intervals along the length of the loading rack 5 on the worktable 1. Each limiting block 8 corresponds to the position of a pneumatic clamp 7 to support and assist in positioning the stainless steel round bars. Furthermore, the top of each limiting block 8 has a V-shaped limiting groove, which helps improve the support stability and repeatability of the stainless steel round bars. Symmetrically distributed... The first electric guide rail 9 and two first electric guide rails 9 are slidably connected to the moving platform 10. On the side of the moving platform 10 near the loading rack 5, three or more limiting blocks 8 are also arranged at intervals along the length direction. Their structure and arrangement are consistent with the limiting blocks 8 on the worktable 1, forming a symmetrical layout to meet the requirement of simultaneous processing at both ends of the workpiece. Two sets of chamfering tool fixtures 11 are symmetrically arranged on the left and right sides of the moving platform 10 and the worktable 1, respectively, for chamfering the ends of stainless steel round bars. Two sets of laser marking components 12 are arranged inside the two sets of chamfering tool fixtures 11, which can simultaneously complete the chamfering process. The workpiece is marked and printed to achieve traceability of processing information. A milling assembly 13 is set on the worktable 1 behind the chamfering tool fixture 11 for planar milling of the end of the stainless steel round bar. A cutting fluid tank 14 is set below the milling assembly 13 to store coolant and cool the cutting area during processing, thereby effectively extending the tool life and improving the surface quality of the machined surface. A second electric push rod 15 is set on the top of the moving platform 10, with its movable end facing the milling assembly 13, for precise positioning of one end of the stainless steel round bar during milling to prevent processing errors caused by workpiece offset.
[0026] When the equipment is running, the loading rack 5 first receives the stainless steel bars to be processed and supports and limits them with the limit blocks 8. Then, the pneumatic clamp 7 clamps and fixes them. Subsequently, the lifting rod of the first lifting cylinder 3 drives the lifting platform 4 and the loading rack 5 to rise as a whole, causing the stainless steel bars to disengage from the limit blocks 8. At this time, the movable rod of the first electric push rod 6 extends, pushing the loading rack 5 to move backward, bringing the stainless steel bars into the next workstation. Next, the first lifting cylinder 3 controls the lifting platform 4 and the loading rack 5 to descend, so that both ends of the stainless steel bars are re-clamped into the corresponding limit blocks 8. The pneumatic clamp 7 releases the stainless steel bars. Then, the movable rod of the first electric push rod 6 retracts, causing the loading rack 5 to reset, preparing for the feeding of the next stainless steel bar. In addition, the pneumatic clamp 7 in the corresponding position clamps the stainless steel bars again. This cyclical operation allows multiple stainless steel bars to be continuously advanced to the subsequent chamfering and milling stations. When the stainless steel bar reaches the chamfering station, the first electric guide rail 9 drives the moving platform 10 to move in a straight line and adjusts it to a suitable position according to the length of the workpiece so that the chamfering tool fixture 11 can perform precise chamfering on stainless steel bars of different specifications. At the same time, the laser marking component 12 is activated to complete the product marking printing operation. The stainless steel bar that has completed chamfering and marking continues to enter the milling station. At this time, the second electric push rod 15 on the moving platform 10 extends to position and clamp one end of the workpiece, while the milling component 13 performs milling on the other end. Finally, after the stainless steel bar completes the integrated chamfering, marking and milling, the finished product is sent out of the device through the loading rack 5, completing the entire automated processing process.
[0027] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6The workbench 1 has a finished product receiving box 16 near the milling assembly 13 for collecting finished stainless steel bars. A guide plate 17 is fixed to the workbench 1 near the finished product receiving box 16 to guide the workpiece smoothly into the receiving box 16. A material box 18 is provided on the workbench 1 near the chamfering tool fixture 11. A baffle 19 is rotatably mounted on the side of the material box 18. A limiting seat 20 is fixed to the workbench 1 near the material box 18 to support one end of the stainless steel bar to be processed. A guide block 2 is fixed to the workbench 1 in front of the limiting seat 20. 1. A second electric guide rail 22 is provided on the worktable 1 behind the limiting seat 20. A third electric push rod 23 is slidably installed on the second electric guide rail 22. The end of the push rod is connected to a top block 24 for auxiliary positioning of the other end of the stainless steel bar. A top plate 25 is provided on the worktable 1 between the limiting seat 20 and the guide block 21. The top plate 25 is used to receive the stainless steel bar rolling down from the raw material box 18. A second lifting cylinder 26 is provided on the worktable 1 below the top plate 25. Its lifting rod is vertically upward and fixedly connected to the top plate 25 for driving the top plate 25 to move up and down.
[0028] Please see Figure 7 and Figure 8 The top surfaces of the guide plate 17, the limiting seat 20, the guide block 21 and the top plate 25 are all provided with downward inclined slope structures. The design of this inclined slope structure helps the stainless steel round bar to roll smoothly under the action of gravity, thereby realizing the automatic sliding and conveying of the workpiece from the raw material box 18 to the processing station, and from the processing station to the finished product receiving box 16.
[0029] The stainless steel bars to be processed are stored in the raw material box 18. When feeding is required, the baffle 19 is rotated and opened, and placed against the guide block 21, causing the stainless steel bars in the raw material box 18 to roll down one by one to the top of the top plate 25. At this time, the second lifting cylinder 26 drives the top plate 25 to perform intermittent upward movement, lifting only one stainless steel bar at a time to a position flush with the top of the limiting seat 20. The lifted stainless steel bar then rolls down to the top of the limiting seat 20, with one end abutting against the limiting seat 20, achieving initial positioning. At the same time, the second electric guide rail 22 drives the second... The three electric push rods 23 move horizontally along a straight line to the corresponding position. The third electric push rod 23 then pushes the top block 24 to extend and abut against the other end of the stainless steel round bar, completing the precise positioning of both ends so that the subsequent feeding rack 5 can clamp and pick up the material. For the stainless steel round bars that have been chamfered, marked and milled, the feeding rack 5 pushes them onto the guide plate 17, and guides them into the finished product receiving box 16 for centralized collection. This design realizes a complete automated process from automatic feeding of raw materials to automatic collection of finished products, which significantly improves production efficiency and reduces manual intervention.
[0030] Please see Figure 5 and Figure 6 On the worktable 1 behind the milling assembly 13, guide rails 27 are symmetrically arranged front and back. Two guide rails 27 are slidably mounted on a slide block 28. A blower box 29 is fixedly installed on the slide block 28. The side of the blower box 29 is provided with a feed port. An electric grinding disc 30 is embedded inside the feed port for deburring the end of the stainless steel round bar. In addition, the electric grinding disc 30 adopts a replaceable design, and the user can quickly replace the grinding disc with different grit or material according to the processing needs to adapt to deburring operations with different precision requirements. A blower 31 is installed on the top of the blower box 29 for blowing and cleaning the surface of the workpiece after grinding to remove residual debris. A fourth electric push rod 32 is also fixedly installed on the worktable 1 on the side of the blower box 29. Its movable rod is connected to the slide block 28 and is used to drive the slide block 28 to move back and forth along the guide rails 27.
[0031] After the stainless steel bar is milled and flattened, it is pushed to the grinding station by the loading rack 5. At this time, the fourth electric push rod 32 is started, and its movable rod pushes the slide 28 forward along the guide rail 27, so that the end of the stainless steel bar that has been milled and flattened passes through the feed port and enters the air box 29. During this process, the electric grinding disc 30 rotates at high speed to finely grind the milled end face of the stainless steel bar and remove burrs. Then, the blower 31 is started to blow and clean the surface of the workpiece to ensure that there are no metal debris residues and improve the quality of the finished product. After the grinding is completed, the fourth electric push rod 32 drives the slide 28 to retract and reset so that the next workpiece can enter the grinding station.
[0032] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
