Description

Technical Field

[0001] This utility model relates to the field of composite milling machining technology, and in particular to a composite milling gate machining equipment with dual closed-loop control. Background Technology

[0002] In the field of modern precision manufacturing, during the production of injection molded and die-cast parts, sprue gates, as residual parts of the mold gating system, need to be removed by specialized processing equipment to ensure product precision and appearance quality. The dual closed-loop control composite milling sprue gate processing equipment is a high-precision automated equipment developed to meet this need. It integrates mechanical structure design, servo drive technology and intelligent control algorithms. Through the coordinated closed-loop feedback of position loop and speed loop, it realizes real-time correction of tool trajectory. It is widely used in industries with stringent requirements for machining precision, such as aerospace, automobile manufacturing and medical devices, and provides core technical support for efficient and precision milling of complex milling.

[0003] Early sprue machining equipment was mostly modified from ordinary milling machines, mainly consisting of a single-axis feed mechanism, a common asynchronous motor drive system, and an open control system. During machining, manual tool setting and parameter adjustments were relied upon, resulting in low positioning accuracy, low machining efficiency, and poor surface quality. To address these issues, existing dual-closed-loop control composite milling equipment generally adopts an integrated cast iron bed to improve rigidity, incorporates a high-precision linear scale and servo motor to establish a dual-closed-loop system for position and speed, and integrates milling-turning composite functions to reduce process changeover time, significantly improving machining accuracy and stability. However, the design of existing equipment's cooling and chip removal systems still presents challenges. There are still obvious shortcomings. Its cooling system mostly adopts a fixed-direction coolant direct jet structure, and chip removal relies on a single screw conveyor. During the processing, when milling the sprue of magnesium alloy and aluminum alloy materials, a large number of fine metal chips are generated. These chips will adhere to the surface of the worktable guide rail or wrap around the screw blades, resulting in incomplete chip removal. As the processing time accumulates, the accumulation of fine chips will jam the movement of the worktable, causing a sudden change in the friction coefficient of the guide rail, interfering with the position detection signal of the grating ruler, and thus damaging the feedback accuracy of the dual closed-loop control system, causing the processing error to be amplified, and even causing the risk of rigid collision between the tool and the workpiece. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a composite milling gate processing equipment with dual closed-loop control, which aims to improve the problems in the existing technology where the cooling and chip removal system is poorly designed, the fine metal chips are not completely removed, and the accumulation of chips will jam the worktable movement and interfere with the feedback accuracy of the position closed loop.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite milling gate processing equipment with dual closed-loop control, including a straight rail, a worktable slidably connected to the top of the straight rail, a draining mechanism provided at the top of the worktable, and stabilizing blocks fixedly connected to the left and right sides of the straight rail, with a protective mechanism provided on the inner wall of the stabilizing blocks. The excretion mechanism includes a vacuum cleaner, the outer wall of which is located at the top of the inner wall of the workbench. A limit block is fixedly connected to the bottom of the vacuum cleaner, and a baffle is fixedly connected to the bottom of the inner wall of the limit block. A mixer is located at the middle of the bottom of the vacuum cleaner, and a rotating shaft is rotatably connected to the middle of the bottom of the mixer. A turbine blade is fixedly connected to the outer wall of the rotating shaft. A guide tube is fixedly connected to the bottom of the outer wall of the baffle, and a conveying assembly is located at the bottom of the guide tube.

[0006] As a further description of the above technical solution: The protective mechanism includes two fixed blocks. The outer walls of the two fixed blocks are respectively fixedly connected to the inner walls of the two stable blocks. A locking block is slidably connected to the inner wall of each adjacent side of the two fixed blocks. A second spring is provided on each adjacent side of the two locking blocks. A force-bearing block is slidably connected to each adjacent end of each second spring. A pad is fixedly connected to each adjacent side of each force-bearing block. A first spring is provided at the front and rear ends of each opposite side of the two pads.

[0007] As a further description of the above technical solution: The conveying assembly includes a conveying pipe, the top end of the inner wall of the conveying pipe is connected to the bottom end of the conduit, a second rotating shaft is provided at the right end of the inner wall of the conveying pipe, a second turbine blade is fixedly connected to the outer wall of the second rotating shaft, and a discharge port is connected to the left end of the second rotating shaft.

[0008] As a further description of the above technical solution: Handrails are fixedly connected to the top of both stabilizing blocks, and suction cups are fixedly connected to the bottom of both stabilizing blocks.

[0009] As a further description of the above technical solution: Both of the two stabilizing blocks are fixedly connected to baffles on their front and rear sides. A toolbox is provided on the right end of the front baffle, and a timer is provided on the left end of the front baffle.

[0010] As a further description of the above technical solution: A battery box is fixedly connected to the left end of the rear baffle two, and a light is fixedly connected to the top of the battery box.

[0011] As a further description of the above technical solution: A protective plate is fixedly connected to the top of the workbench, and a motor is installed on the right side of the workbench.

[0012] As a further description of the above technical solution: The outer walls of the multiple springs are respectively fixedly connected to the corresponding positions on the adjacent sides of the stabilizing block, and the bottom of the adjacent sides of the two pads are also slidably connected to the left and right sides of the straight rail.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the discharge mechanism achieves directional collection of debris through the fixed structure of the vacuum cleaner and the top of the inner wall of the workbench, combined with the guiding effect of the limiting block and the baffle. The cooperation of the mixer, the rotating shaft and the turbine blade can crush large pieces of debris and push them out through the conduit, which solves the problem of incomplete debris discharge in the prior art and improves the stability of equipment operation.

In this utility model, by fixing the fixed block and the stabilizing block, when a collision occurs, the pad first compresses the spring one for initial buffering, and the force block simultaneously squeezes the spring two to push the locking block to engage with the fixed block for limiting. This solves the problem of insufficient rigidity of the bed in the prior art, reduces the impact of collision caused by high-speed milling resonance, avoids equipment damage due to collision, and improves the safety of equipment operation.

A locking block 305 is slidably connected to the inner wall of each adjacent side of the two fixing blocks 306. The locking block 305 can slide along the inner wall of the fixing block 306 to achieve a limiting function. A second spring 304 is provided on each adjacent side of the two locking blocks 305. The second spring 304 can absorb collision energy through elastic deformation. A force-bearing block 303 is slidably connected to each adjacent end of the two second springs 304. The force-bearing block 303 transmits the collision force to the second spring 304. The adjacent sides of the two force-bearing blocks 303 are fixedly connected to the pads 301. The pads 301 directly bear the impact force of the workbench 4. The front and rear ends of the opposite sides of the two pads 301 are provided with springs 302. Springs 302 can provide a first-level buffer to reduce the impact intensity. The outer walls of multiple springs 302 are fixedly connected to the corresponding positions on the adjacent sides of the stabilizing block 5 to ensure that the springs 302 are installed firmly. The bottom of the adjacent sides of the two pads 301 are also slidably connected to the left and right sides of the straight rail 1 to ensure that the pads 301 move smoothly along the straight rail 1 when subjected to force. Specifically, the two fixed blocks 306 in the protective mechanism 3 serve as the mounting base for the protective mechanism 3. Their outer walls are fixedly connected to the inner walls of the two stabilizing blocks 5, respectively, forming a stable connection between the protective mechanism 3 and the stabilizing blocks 5, providing reliable support for the entire protective mechanism 3. The locking blocks 305, which are slidably connected to the inner walls of adjacent sides of the two fixed blocks 306, can slide along the inner walls of the fixed blocks 306, achieving a limiting function during collision.

[0020] Reference Figure 4 and Figure 6The conveying assembly 208 includes a conveying pipe 2081, which provides a final conveying channel for the debris. The top of the inner wall of the conveying pipe 2081 is connected to the bottom of the guide tube 207, so that the debris conveyed by the guide tube 207 can smoothly enter the conveying pipe 2081. A rotating shaft 2082 is provided at the right end of the inner wall of the conveying pipe 2081. The rotating shaft 2082 provides rotational driving force for the turbine blade 2083. The turbine blade 2083 is fixedly connected to the outer wall of the rotating shaft 2082. The turbine blade 2083 pushes the debris to move towards the discharge port 2084 by rotation. The left end of the rotating shaft 2082 is connected to the discharge port 2084, which discharges the debris out of the equipment to complete the chip removal process. Specifically, the conveying pipe 2081 in the conveying assembly 208 serves as the final conveying channel for debris. The top of its inner wall is connected to the bottom of the guide tube 207, allowing the debris conveyed by the guide tube 207 to smoothly enter the conveying pipe 2081, achieving orderly transfer of debris between different conveying components. The rotating shaft 2082, located at the right end of the inner wall of the conveying pipe 2081, provides rotational driving force for the turbine blade 2083, which is fixedly connected to its outer wall, causing the turbine blade 2083 to rotate. The turbine blade 2083 generates a pushing force through rotation, pushing the debris entering the conveying pipe 2081 to move to the left along the pipe, ensuring that the debris does not accumulate or block during the conveying process. The discharge port 2084, connected to the left end of the rotating shaft 2082, receives the debris pushed by the turbine blade 2083 and discharges the debris out of the equipment, completing the entire chip removal process.

[0021] Reference Figure 1 , Figure 2 and Figure 3 Each of the two stabilizing blocks 5 has a handle 6 fixedly connected to its top, which facilitates the operator's movement or transport of the equipment. Each of the two stabilizing blocks 5 has a suction cup 7 fixedly connected to its bottom, which enhances the stability of the equipment during placement through suction. Each of the two stabilizing blocks 5 has a second baffle 8 fixedly connected to its front and rear sides, which prevents processing debris from splashing forward and backward. A toolbox 9 is located on the right end of the front baffle 8, used to store processing tools and spare parts. A timer 10 is located on the left end of the front baffle 8. The timer 10 can record the processing time for easy process management. The battery box 11 is fixedly connected to the left end of the rear baffle 2 8. The battery box 11 provides power for the auxiliary electrical appliances of the equipment. The top of the battery box 11 is fixedly connected to the lighting lamp 12. The lighting lamp 12 provides lighting to ensure the processing vision when the light is insufficient. The top of the worktable 4 is fixedly connected to the guard plate 13. The guard plate 13 blocks the debris that flies upward during processing. The right side of the worktable 4 is equipped with a motor 14. The motor 14 provides power output to the discharge mechanism 2 and the conveying assembly 208. Specifically, the handles 6 fixedly connected to the top of the two stabilizing blocks 5 provide a gripping fulcrum for operators to move or transport the equipment, facilitating equipment position adjustment and handling. The suction cups 7 fixedly connected to the bottom of the two stabilizing blocks 5 enhance the stability of the stabilizing blocks 5 and the entire equipment through adsorption with the placement surface, preventing displacement of the equipment during processing. The baffles 8 fixedly connected to the front and rear sides of the two stabilizing blocks 5 cooperate with the guard plate 13 on the top of the workbench 4. The guard plate 13 blocks upward-splashing debris during processing, while the baffles 8 prevent debris from splashing in the front and rear directions of the equipment, together forming an all-round anti-splash protection to prevent debris from scattering and polluting the environment or injuring operators. The toolbox 9 set at the right end of the front baffle 8 is used for centralized storage of processed materials. The necessary tools and spare parts are readily available for operators. The timer 10 installed on the left end of the front baffle 2 8 can record the processing time in real time, providing time data support for processing technology management. The battery box 11 fixedly connected to the left end of the rear baffle 2 8 provides power to the lighting lamp 12 fixedly connected to its top. The lighting lamp 12 is turned on when the light is insufficient to ensure the illumination of the processing area and ensure that the processing operation is clearly visible. The DD motor 14 with a model of 10-50N・m is installed on the right side of the worktable 4 to provide power output to the discharge mechanism 2 and the conveying component 208, driving the discharge mechanism 2 to complete the absorption, crushing and preliminary conveying of debris, and at the same time driving the conveying component 208 to finally discharge the debris from the equipment, realizing the automated cleaning of processing debris.

[0022] Working principle: When processing debris is generated on the worktable 4, the DD motor 14 (model 10-50 N·m) is activated to drive the chip removal process. The motor 14 first drives the vacuum cleaner 201 to start, absorbing the debris from the surface of the worktable 4. The debris is then conveyed through the guide channel formed by the limit block 202 and the baffle 203 to prevent it from scattering onto the straight rail 1. For large pieces of debris, the mixer 204 performs secondary crushing. The crushed debris enters the guide tube 207, where the turbine blade 206, driven by the rotating shaft 205, continuously rotates and pushes the debris through the spiral propulsion force. To prevent fine debris from accumulating in the pipe and completely avoid blockage, after the debris enters the conveying pipe 2081 through the conduit 207, the motor 14 synchronously drives the rotating shaft 2082, which in turn drives the turbine blade 2083 to further accelerate and push the debris. Finally, all the debris is discharged from the equipment through the discharge port 2084. The guard plate 13 can block the debris from splashing during processing. The discharge mechanism 2 slides synchronously along the straight rail 1 with the worktable 4 to ensure that the chip discharge is precisely aligned with the processing position throughout the process, thoroughly removing fine metal chips and preventing them from jamming the movement of the worktable 4 and interfering with the position closed-loop feedback accuracy. Furthermore, when the workbench 4 loses control and crashes into the stabilizing block 5 along the straight rail 1, the workbench 4 impacts the pad 301. After being subjected to force, the pad 301 compresses the first spring 302. The first spring 302 generates a reverse buffering force to offset the impact force. Simultaneously, the pad 301 pushes the force-bearing block 303, which squeezes the second spring 304, causing the second spring 304 to further attenuate the collision kinetic energy. During the compression process of the second spring 304, its thrust drives the locking block 305 to move and engage with the bottom of the fixed block 306, limiting the excessive displacement of the workbench 4, avoiding component misalignment or structural deformation caused by collision offset, effectively absorbing collision energy and limiting displacement, and ensuring the structural stability of the equipment.
