Description

Technical Field

[0001] This utility model relates to the field of non-standard automated mechanical equipment, specifically to an automatic metal rod milling machine. Background Technology

[0002] In the modern kitchenware manufacturing industry, metal mesh frames and baskets have become core components in kitchen appliances, cookware accessories and other products due to their excellent durability and ventilation. They are widely used in various scenarios such as oven racks, dishwasher baskets, and wok guards. Their structural stability directly affects the service life and safety of kitchenware products.

[0003] To ensure the structural strength of metal mesh frames and baskets meets the load-bearing requirements of daily use, traditional manufacturing processes typically use solid metal rods as the external frame or internal support rods. However, this design has significant drawbacks in practical applications: Firstly, the high density of solid metal rods results in a larger amount of raw materials required per product, directly increasing raw material procurement costs. For the large-scale mass production model prevalent in the kitchenware industry, a small increase in unit product cost can be amplified into a significant increase in overall production costs, severely compressing manufacturers' profit margins and weakening the product's price competitiveness in the market. Secondly, the weight of solid metal rods makes the finished metal mesh frames and baskets heavier, reducing the convenience of product use, increasing the difficulty and cost of warehousing and transportation, and also causing inconvenience during installation. Especially for kitchenware accessories that require frequent movement, the excessively heavy structural design clearly contradicts the trend of lightweight product development.

[0004] In recent years, to reduce costs and weight while ensuring product structural strength and performance, optimized design solutions have emerged in the industry. These solutions utilize a composite structure with an outer metal tube and an inner metal rod to replace traditional solid metal rods, forming the frame and support rods of metal mesh frames or baskets. This hollow composite structure reduces the total amount of metal material used while maintaining overall structural strength and stability, effectively lowering raw material costs. Simultaneously, the hollow design significantly reduces the overall weight of the product, making the metal mesh frames and baskets easier to handle, transport, and install. This aligns with the modern demand for lightweight and convenient kitchenware and has gradually become the mainstream design direction in the industry.

[0005] However, regardless of whether it's a traditional solid metal rod or a new type of hollow composite metal rod, after the main structure is processed, its ends require precision machining such as cutting, milling, and grinding to achieve specific dimensions and surface precision that meet subsequent assembly requirements. Specifically, the ends of the metal rods need to be cut to a preset length to match the splicing dimensions of the mesh frame, specific shaped interfaces need to be milled to meet the needs of tube assembly, and burrs need to be removed by grinding to avoid scratching users or affecting assembly accuracy during use. Currently, the cutting, milling, and grinding of metal rod ends in the industry is still mainly done manually. Operators need to use simple cutting tools, hand-held milling cutters, grinding wheels, and other equipment to complete the processing step by step. This processing method is inefficient, manual operation depends on the operator's skill level, and the processing cycle for a single metal rod is long. It is difficult to meet the high-efficiency processing requirements of large-scale production of metal mesh frames and baskets, easily causing production bottlenecks and affecting the overall production progress. Secondly, processing quality is difficult to guarantee. The stability of manual operation is affected by various factors such as the operator's experience, physical condition, and adherence to operating procedures. This leads to inconsistent processing dimensional accuracy and surface smoothness at the ends of metal rods from different batches, and even within the same batch. Some products may have issues such as tilted end cutting, milling dimensional deviations, or incomplete grinding. These quality defects not only make subsequent pipe assembly difficult, requiring additional rework and correction, but in severe cases, mismatched end dimensions can result in excessive gaps in the mesh frame splicing, affecting the product's structural stability. Furthermore, incomplete removal of end burrs can pose safety hazards to users, hindering the consistency and stability of metal mesh frames and baskets.

[0006] Therefore, how to overcome the above-mentioned defects and provide a device that can automatically cut, mill, and grind the ends of metal rods in an integrated manner to solve the shortcomings of existing processing methods and meet the industry's needs for large-scale, high-precision, and high-efficiency production has become an important issue that needs to be addressed by those skilled in the art. Utility Model Content

[0007] This invention overcomes the shortcomings of the above-mentioned technologies and provides an automatic metal rod milling machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An automatic metal rod milling machine includes a frame, which includes a mounting platform. The mounting platform is equipped with a feeding platform, a rolling mechanism mounted at the front end of the feeding platform, a receiving mechanism mounted at the front end of the rolling mechanism, a transferring mechanism mounted at the front end of the receiving mechanism, and a bench lathe mounted to the left of the transferring mechanism. The bench lathe includes a spindle box assembly mounted to the left of the transferring mechanism, a cutting mechanism mounted to the left of the spindle box assembly, and a milling mechanism. A discharge guide groove connected to the left side of the milling mechanism is also mounted on the mounting platform. The rolling mechanism transfers material from the feeding platform to the receiving mechanism. The receiving mechanism receives the material transferred from the rolling mechanism for the transferring mechanism to transfer the material to the spindle box assembly of the bench lathe. The cutting mechanism cuts the material, and the milling mechanism mills the material.

[0009] Furthermore, the feeding platform includes a fixed plate arranged symmetrically on the left and right sides. A feeding guide rail is fixedly connected to the inner side wall of the fixed plate. The feeding guide rail is inclined toward the rolling mechanism and its front end is connected to the feeding mechanism. A receiving cavity for placing materials is formed between the two feeding guide rails.

[0010] Furthermore, the rolling mechanism includes fixed seats arranged symmetrically on the left and right, a rotating shaft rotatably connected to the two fixed seats, a turntable disposed on the rotating shaft and capable of rotating synchronously with the rotating shaft, and a first motor connected to one end of the rotating shaft for driving the rotating shaft to rotate. The turntable is located between the two fixed seats, and a plurality of first receiving grooves for receiving materials are equally spaced on the outer peripheral wall of the turntable. The fixed seats include an inclined surface inclined toward the receiving mechanism and a material blocking part.

[0011] Furthermore, the turntable includes a main turntable and an auxiliary turntable with a length shorter than the main turntable. The main turntable and the auxiliary turntable are coaxially connected by a rotating shaft and rotate synchronously. Both the main turntable and the auxiliary turntable can move left and right on the rotating shaft to adjust their positions on the rotating shaft. A first slide rail is also installed on the mounting platform, and the lower end of the fixed seat on one side is slidably connected to the first slide rail by a first pneumatic slider.

[0012] Furthermore, the receiving mechanism includes a first receiving platform disposed at the front end of the rolling mechanism and a second receiving platform disposed to the left of the first receiving platform. The lower end of the first receiving platform is connected to the mounting platform through a first cylinder. Both the first receiving platform and the second receiving platform are provided with a second receiving groove. The second receiving platform is fixedly installed on the mounting platform through a fixed bracket.

[0013] Furthermore, the material transfer mechanism includes a support frame, an X-axis linear module mounted on the support frame, a slide block slidably connected to the X-axis linear module via a second pneumatic slider, a pusher head connected to the slide block, and a pusher rod mounted on the pusher head, wherein the pusher rod is detachably connected to the pusher head.

[0014] Furthermore, the spindle box assembly includes a box body and a spindle that can drive the material to rotate, which is installed through the box body from left to right. A second cylinder is also installed on the mounting platform. A connecting rod is connected to the left end of the second cylinder. The front end of the connecting rod is connected to the spindle through a collar. A chuck located on the right side of the collar is also fitted on the spindle. When the second cylinder extends or retracts, it drives the collar to swing left and right, thereby realizing the clamping / releasing of the material by the chuck.

[0015] Furthermore, the cutting mechanism includes a mounting bracket mounted on the upper left side of the spindle box assembly, a third cylinder mounted on the mounting bracket, and a first cutter slidably connected to the mounting bracket. The upper end of the first cutter is connected to the third cylinder so that it moves up and down under the drive of the third cylinder. A second slide rail is provided on the mounting bracket, and the first cutter is slidably connected to the second slide rail via a third slider.

[0016] Furthermore, the milling mechanism includes a Y-axis linear module and a milling platform slidably connected to the Y-axis linear module. The milling platform includes a turning and milling device and a grinding device arranged in front of and behind the unloading guide groove. The turning and milling device includes a second cutting tool, and the grinding device includes a second motor and a grinding wheel connected to the motor shaft of the first motor.

[0017] Furthermore, the mounting platform is also provided with a third slide rail extending to the left and right. Two third slide rails are symmetrically arranged. A base plate is slidably connected to the third slide rail. The feeding platform, the rolling mechanism, and the receiving mechanism are all fixedly installed on the base plate. The lower end of the base plate is slidably connected to the two third slide rails through a third pneumatic slider.

[0018] Compared with the prior art, the beneficial effects of this utility model are: The automatic metal rod milling machine in this case integrates all the mechanisms required in the processing steps into a single machine, automating each step and thus achieving full automation of the metal rod milling process. The loading platform automates the manual placement of materials, followed by a rolling mechanism that transfers the material to a receiving mechanism. This receiving mechanism then picks up the material from the rolling mechanism and feeds it to a transfer mechanism, which in turn transfers it to the spindle box assembly of a bench lathe. The spindle box assembly then transports the material to the next process step, where a cutting mechanism cuts the material to the required length. Finally, a milling mechanism mills the material, and the material is automatically unloaded through a discharge guide. This automatic metal rod milling machine effectively solves the various problems associated with manual operation, significantly improves production efficiency, reduces defect rates, lowers labor costs, and brings greater economic benefits.

[0024] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art: For ease of description and understanding, please refer to the orientation shown in the attached diagram for descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside, as well as descriptions related to the X, Y, and Z axes.

[0025] The automatic metal rod milling machine in this case is an integrated processing equipment for cutting, milling and grinding the ends of round hollow or solid metal rods. The metal rod is referred to in the attached drawings of the instruction manual (hereinafter referred to as material 200).

[0026] like Figures 1 to 5 As shown, this invention provides an automatic metal rod milling machine, including a frame 100, which includes a mounting table 101. The mounting table 101 provides a mounting support surface for various mechanisms on the machine. A feeding platform 1, a rolling mechanism 2 mounted at the front end of the feeding platform 1, a receiving mechanism 3 mounted at the front end of the rolling mechanism 2, a transferring mechanism 4 mounted at the front end of the receiving mechanism 3, and a bench lathe mounted to the left of the transferring mechanism 4 are mounted on the mounting table 101. The bench lathe includes a spindle box assembly 5 mounted to the left of the transferring mechanism 4, a cutting mechanism 6 mounted to the left of the spindle box assembly 5, and a milling mechanism 7. A discharge guide groove 102 connected to the left side of the milling mechanism 7 is also mounted on the mounting table 101.

[0027] The feeding platform 1 is used for manually placing materials and provides a temporary storage station for materials 200, ensuring a sufficient supply of materials for subsequent processes. The rolling mechanism 2 is used to transfer materials 200 from the feeding platform 1 to the receiving mechanism 3. The receiving mechanism 3 is used to receive the materials 200 transferred from the rolling mechanism 2 so that the transfer mechanism 4 can transfer the materials to the spindle box assembly 5 of the bench lathe. That is, the receiving mechanism 3 connects the rolling mechanism 2 and the transfer mechanism 4, and provides a temporary storage station for materials, cooperating with the transfer mechanism 4. The cutting mechanism 6 is used to cut the ends of the materials 200 to ensure that the ends are flat and that the lengths of each material 200 are consistent. The milling mechanism 7 is used to mill the materials 200, shaping and smoothing the ends, and finally, the materials 200 are automatically unloaded through the unloading guide groove 102. In practice, a central control system is also installed on the installation platform 101. The central control system generally consists of a computer control system, sensors, actuators, etc., and is responsible for monitoring and controlling the operation of the entire automated equipment. This is a technology known to those skilled in the art, and will not be elaborated on here.

[0028] The automatic metal rod milling machine provided in this case, through the synergistic cooperation of the aforementioned technical features, forms a fully automated processing flow encompassing feeding, transfer, positioning, clamping, cutting, milling, and unloading. Compared to traditional manual processing methods, this significantly improves processing efficiency. The coordinated operation of various mechanisms enables continuous processing of material 200, greatly shortening the processing cycle and facilitating large-scale mass production. Simultaneously, the precise coordination of automated machinery effectively ensures the consistency and stability of material 200 processing compared to manual methods, greatly improving the product qualification rate.

[0029] It should be further explained that, in specific implementation, this invention uses multiple sensor switches to detect the presence or absence of objects and their positioning, thereby triggering the device's action or changing its state. This is well-known technology in the field, and will not be described in detail for each sensor switch. In specific implementation, those skilled in the art can, based on common knowledge in the field and in conjunction with this invention, set sensor switches in appropriate locations to achieve the linkage of various mechanisms.

[0030] Specifically, such as Figures 1-3As shown, the feeding platform 1 includes symmetrically arranged fixed plates 11, with feeding guide rails 12 fixedly connected to the inner sidewalls of the fixed plates 11. The fixed plates 11 are symmetrically arranged frame structures used to support and fix the feeding guide rails 12. The feeding guide rails 12 facilitate the smooth conveying of the material 200 and improve its conveying speed. In specific implementation, the feeding guide rails 12 are rod-shaped, and the rod-shaped design allows the material 200 to roll faster. The feeding guide rails 12 are inclined towards the rolling mechanism 2, and their front ends are connected to the feeding mechanism 2. The inclined feeding guide rails 12 can automatically guide the material 200 to slide from back to front. Through a simple structure, automatic transportation of the material 200 is achieved, which is beneficial for cost savings. A receiving cavity 13 for placing the material is formed between the two feeding guide rails 12, used to accommodate and position the material 200. Preferably, the fixing plates 11 on both sides are detachably connected to the mounting platform 101 by bolts, so that the position of the fixing plates 11 can be adjusted adaptively when materials of different lengths and sizes need to be replaced.

[0031] Continue to refer to Figures 1-3 As shown, the rolling mechanism 2 includes symmetrically arranged fixed seats 21, a rotating shaft 22 rotatably connected to the two fixed seats 21, a turntable 23 mounted on the rotating shaft 22 and rotating synchronously with the rotating shaft 22, and a first motor 24 connected to one end of the rotating shaft 22 for driving the rotating shaft 22 to rotate. In specific implementation, the fixed seats 21 provide a stable mounting reference for the rotating shaft 22 and the turntable 23, ensuring the stability of the installation. The rotating shaft 22 is used to drive the turntable 23 to transfer the material 200 from the loading platform 1 forward to the receiving mechanism 3 by rotation. In specific implementation, both ends of the rotating shaft 22 extend out of the fixed seats 21 on both sides, and one end is connected to the motor 24. The motor 24 is used to drive the rotating shaft 22 to rotate, providing a power source for the entire rolling mechanism 2. Preferably, the motor 24 is a stepper motor. The turntable 23 is located between the two fixed seats 21, and a plurality of first receiving slots 230 for receiving materials are equidistantly opened on the outer peripheral wall of the turntable 23. The first receiving groove 230 is provided to accommodate and restrict the material 200 from falling off during rotation, ensuring the stability of the conveying process. Specifically, the first receiving groove 230 is a cylindrical tube with an inclined surface, and the depth of the groove is greater than the diameter of the material 200, so that it can better hold the material 200 and facilitate its entry. The fixed base 21 includes an inclined surface 211 and a baffle 212 inclined towards the receiving mechanism 3. The inclined surface 211 guides the material 200 conveyed forward by the turntable 23 to continue sliding forward by natural gravity, resulting in a simple structure and avoiding unnecessary components. The baffle 212 blocks the material 200 sliding down the inclined surface 211 to ensure its positional accuracy and prevent the material 200 from falling off.

[0032] Furthermore, continue to refer to Figures 1-3As shown, in this embodiment, the turntable 23 includes a main turntable 231 and an auxiliary turntable 232, which is shorter than the main turntable 231. The main turntable 231 and the auxiliary turntable 232 are coaxially connected and rotate synchronously via a rotating shaft 22. Both the main turntable 231 and the auxiliary turntable 232 can be moved left and right on the rotating shaft 22 to adjust their positions on the shaft 22. In specific implementation, both the main turntable 231 and the auxiliary turntable 232 are fixed to the rotating shaft by bolts. Under normal conditions, they are fixed on the rotating shaft. When encountering materials 200 of different lengths, it is necessary to adjust the relative distance between the main turntable 231 and the auxiliary turntable 232 to accommodate the length of the metal rod. After loosening the screws, the main turntable 231 or the auxiliary turntable 232, or both, can be slid on the rotating shaft 22. This structure can adapt to materials 200 of different specifications and lengths, enabling rapid changeover operations for the equipment, reducing equipment downtime during changeovers, and improving production efficiency. To further improve changeover efficiency, a first slide rail 103 is also installed on the mounting platform 101. The lower end of the fixed seat 21 on one side is slidably connected to the first slide rail 103 via a first pneumatic slider 25. By pneumatically controlling the sliding of the fixed seat 21 on one side, the operator can directly and quickly adjust the width of the rolling mechanism 2 through the control panel.

[0033] Reference Figures 1-3 As shown, the receiving mechanism 3 of this case includes a first receiving platform 31 located at the front end of the rolling mechanism 2 and a second receiving platform 32 located to the left of the first receiving platform 31. In specific implementation, the first receiving platform 31 is used to initially receive the material 200 transferred from the rolling mechanism 2, realizing the first step of material transition from the rolling mechanism to the receiving mechanism; the second receiving platform 32 is used to receive the material from the first receiving platform 31 during the movement of the transfer mechanism 4, which is equivalent to connecting the first receiving platform 31 and the main box assembly 5. Through the joint cooperation of the first receiving platform 31 and the second receiving platform 32, the stability of the material 200 when driven by the transfer mechanism 4 is ensured. The lower end of the first receiving platform 31 is connected to the mounting platform 101 through a first cylinder 33. Through the lifting action of the first cylinder 33, the material can be lifted to a height matching the second receiving platform 32, which is convenient for subsequent transfer to the second receiving platform 32. When the first cylinder 33 descends, it is convenient to receive the material 200 conveyed by the rolling mechanism 2. The second receiving platform 32 is fixedly mounted on the mounting platform 101 by a fixed bracket 34 to ensure its height position is fixed and to facilitate matching the height of the material transfer mechanism 4. Both the first receiving platform 31 and the second receiving platform 32 are provided with a second receiving groove 312. When the first receiving platform 31 is driven to rise by the first cylinder 33, the two second receiving grooves 312 are in a coaxial and collinear position so that the axis of the second receiving groove 312 is aligned with the clamping axis of the spindle box assembly 5, ensuring that the material transfer mechanism 4 can accurately feed the material into the spindle box after picking it up.

[0034] Reference Figure 1 , Figure 2 , Figure 4 As shown, the material transfer mechanism 4 in this case includes a support frame 41, an X-axis linear module 42 mounted on the support frame 41, a slide block 44 slidably connected to the X-axis linear module 42 via a second pneumatic slider 43, a pusher head 45 connected to the slide block 44, and a pusher rod 46 mounted on the pusher head 45. Two support frames 41 are symmetrically arranged to fix and support the entire material transfer mechanism 4, ensuring stable installation of the material transfer mechanism 4. The slide block 44 reciprocates on the X-axis linear module 42, thereby transferring the material 200 from the receiving structure 3 to the spindle box assembly 5. In specific implementation, the pusher rod 46 is a vertical rod facing the receiving mechanism 3. The pusher rod 46 pushes the material 200 and moves it continuously to the left until the material 200 moves onto the spindle box assembly 5. In specific implementation, the diameter of the pusher rod 46 matches the diameter of the material to ensure precise alignment with the end of the material 200, ensuring the smoothness and accuracy of the push. The push rod 46 is detachably connected to the push head 45 so that it can be adapted to different types of materials 200 by replacing push rods 46 of different sizes. The detachable nature of the push rod 46 allows for replacement and height adjustment, making it more versatile.

[0035] Reference Figure 1 , Figure 2 , Figure 5 As shown, the spindle box assembly 5 includes a housing 51 and a spindle 52, which is installed through the housing 51 and can drive the material to rotate. In a specific implementation, the housing 51 provides the basic functions of the spindle box, mainly for clamping and rotating the material. Inside the housing 51 are also conventional components required by this mechanism, such as spindle bearing seats and transmission gear cavities. This is technology well known to those skilled in the art. Other structures of the spindle box not mentioned in this case can be adapted using the general structure of a bench lathe in this field. A second cylinder 53 is also installed on the mounting table 101. The left end of the second cylinder 53 is connected to a connecting rod 54. The front end of the connecting rod 54 is connected to the spindle 52 via a collar 55. A chuck 56 is also fitted on the spindle 52, located to the right of the collar 55. When the second cylinder 53 extends or retracts, it drives the collar 55 to swing left and right, thereby achieving the clamping / releasing of the material by the chuck 56. In a specific implementation, the chuck 56 can be a three-jaw chuck commonly used in the prior art.

[0036] Continue to refer to Figure 1 , Figure 2 , Figure 5As shown, the cutting mechanism 6 of this invention includes a mounting bracket 61 mounted on the upper left side of the spindle box assembly 5, a third cylinder 62 mounted on the mounting bracket 61, and a first cutter 63 slidably connected to the mounting bracket 61. The upper end of the first cutter 63 is connected to the third cylinder 62, thereby moving up and down under the drive of the third cylinder 62. A second slide rail 64 is provided on the mounting bracket 61, and the first cutter 63 is slidably connected to the second slide rail 64 via a third slider 65. In specific implementation, the third cylinder 62 is securely mounted on the upper left side of the spindle box assembly 5 housing 51 via the mounting bracket 61. When the material 200 in the spindle box assembly 5 is conveyed to the preset position, it drives the material to rotate 200, and then the third cylinder 62 drives the first cutter 63 to slide downward to perform a cutting operation on the end of the material 200, so that the length and flatness of the material 200 meet the predetermined requirements.

[0037] Continue to refer to Figure 1 , Figure 2 , Figure 5 As shown, the milling mechanism 7 includes a Y-axis linear module 71 and a milling platform 72 slidably connected to the Y-axis linear module 71. That is, the movement direction of the Y-axis linear module 71 is perpendicular to the axis of the main spindle 52, driving the milling platform 72 to move smoothly back and forth, thereby realizing the milling operation of the material 200 after the cutting process. The milling platform 72 includes a milling / turning device 73 and a grinding device 74 arranged relative to the material guide groove 102. That is, there is a certain distance between the milling / turning device 73 and the grinding device 74 to ensure that they do not interfere with each other during processing, while simultaneously achieving synchronous feeding of both through the drive of the Y-axis linear module 71, eliminating the need to adjust the positions of the two devices separately, effectively saving installation space. The reciprocating movement of the Y-axis linear module 71 realizes the process switching between the milling / turning device 73 and the grinding device 74 on the milling platform 72. The milling and turning device 73 includes a second cutting tool 731, which turns or mills the outer diameter of the material 200 to remove burrs and excess material after cutting, providing a regular reference surface for subsequent grinding. The grinding device 74 includes a second motor 741 and a grinding wheel 742 connected to the motor shaft of the first motor 741. After the milling and turning process is completed, the second motor 741 drives the grinding wheel 742 to rotate at high speed, which is driven to approach the material through the Y-axis linear module 71 to grind and polish the surface of the milled material 200, removing tool marks, improving surface finish, and meeting the appearance and assembly requirements of the product. The milling and grinding mechanism in this case achieves high-precision forming and surface treatment of materials in an automated process through integrated milling, turning and grinding and precise feed control, greatly improving processing efficiency and product quality.

[0038] As shown in the figure, another embodiment of this invention involves adjusting the distance between these mechanisms and the bench lathe, particularly the distance between these mechanisms and the spindle box 5, to better accommodate materials of different lengths. Specifically, the mounting table 101 is equipped with two symmetrically arranged third slide rails 104 extending left and right. A base plate 105 is slidably connected to each third slide rail 104. The feeding platform 1, the rolling mechanism 2, and the receiving mechanism 3 are all fixedly mounted on the base plate 105. The lower end of the base plate 105 is slidably connected to the two third slide rails 104 via a third pneumatic slider 106. This adjustment mechanism integrates the various mechanisms and achieves a one-time unified adjustment through the sliding connection of the third pneumatic slider 106 to the two third slide rails 104. When processing products of different sizes, only simple adjustments are needed, rather than replacing the entire equipment or a large number of parts, thus significantly reducing downtime and conversion costs. The adjustment function allows the equipment to quickly adapt to changes in the production line in a short time, improving the flexibility and response speed of the production line.

[0039] It should be further noted that linear modules are a well-known technology in this field. Currently, widely used linear modules can be divided into three types: synchronous belt type, ball screw type, and linear motor type, which will not be elaborated upon here. Unless otherwise specified, the linear modules mentioned in this case are preferably linear motor type linear modules, which generally include components such as linear guides, ball screws, and motors. This type of linear module has a simple structure, high acceleration, fast response, high precision, and facilitates long-stroke movement.

[0040] The following is a description of how this case works, based on the entire text: The complete working principle of the automatic metal rod milling machine in this case can be divided into three stages: initialization preparation, automated processing cycle and changeover adjustment. The various mechanisms cooperate with each other to achieve fully automated operation.

[0041] During the initialization preparation phase, the operator, based on the specifications of the metal rod to be processed (material 200), first completes the adaptation and adjustment of each mechanism: adjusts the distance between the main turntable 231 and the auxiliary turntable 232 in the rolling mechanism 2 and the position of the fixed seat 21 on the same side (sliding along the first slide rail 103 via the first pneumatic slider 25), replaces the push rod 46 in the material transfer mechanism 4 with one that matches the diameter of the material 200, and drives the base plate 105 to slide along the third slide rail 104 via the third pneumatic slider 106 as needed, simultaneously adjusting the loading platform 1. The relative distance between the rolling mechanism 2, the receiving mechanism 3 and the spindle box assembly 5 is determined by the central control system. The cutting length, spindle speed 52, feed amount of Y-axis linear module 71 and action sequence of each cylinder (first cylinder 33, second cylinder 53, third cylinder 62) are preset. Then, the materials to be processed 200 are placed in batches into the receiving cavity 13 of the loading platform 1. The materials 200 are naturally attached to the guide rail under the guidance of the inclined loading guide rail 12. After the operator checks that each mechanism is reset, the equipment enters the ready-to-start state.

[0042] After entering the automated processing cycle, the process proceeds continuously according to the following steps: First, the material 200 in the receiving cavity 13 of the feeding platform 1 slides along the inclined feeding guide rail 12 to the rolling mechanism 2. The first motor 24 drives the rotating shaft 22 to rotate the main turntable 231 and the auxiliary turntable 232. The first receiving groove 230 on the outer periphery of the turntable 23 receives the material 200 and is conveyed forward with the turntable 23. When the material 200 reaches the top of the inclined surface 211 of the fixed seat 21, it slides down the inclined surface 211 under the action of gravity and is blocked by the material blocking part 212. Positioning; then, the first cylinder 33 drives the first receiving platform 31 to rise to be flush with the second receiving platform 32. After the material 200 slides into the second receiving groove 312 of the first receiving platform 31, the first receiving platform 31 detects the material 200 and sends a signal to the transfer mechanism 4; the second pneumatic slider 43 of the transfer mechanism 4 drives the slide block 44 to move to the left along the X-axis linear module 42, during which the material 200 passes through the second receiving groove 312 of the second receiving platform 32; the first receiving platform 31 descends and resets until the push rod 46 is pressed against it. Material 200 is pushed into the three-jaw chuck 56 of the spindle box assembly 5; then, the second cylinder 53 drives the collar 55 to move, causing the chuck 56 to clamp the material 200, and the material transfer mechanism 4 resets; afterwards, the spindle 52 drives the material 200 to rotate, and the third cylinder 62 of the cutting mechanism 6 drives the first cutter 63 to move downward along the second slide rail 64 to complete the fixed-length cutting of the material 200. After the first cutter 63 resets, the Y-axis linear module 71 drives the milling platform 72 to approach the material 200, and the second cylinder of the milling device 73... The cutting tool 731 first turns or mills the end of the material 200 to remove burrs and excess material. Then, the second motor 741 of the grinding device 74 drives the grinding wheel 742 to rotate at high speed to polish the surface of the milled material 200. After the milling is completed, the milling platform 72 returns to the safe position. Finally, the spindle 52 stops rotating, the chuck 56 opens, and the processed material 200 slides into the receiving box along the unloading guide groove 102 on the left side of the milling mechanism 7 under the action of gravity. The equipment then enters the processing cycle of the next material 200.

[0043] When processing materials 200 of different specifications, a changeover adjustment is initiated: For length adaptation, minor changes can be made by adjusting the distance between the main turntable 231 and the auxiliary turntable 232 (by loosening the bolts and sliding) and the position of the fixed seat 21 (via the first pneumatic slider 25); for significant changes, the base plate 105 is adjusted along the third slide rail 104 via the third pneumatic slider 106. For diameter adaptation, the push rod 46 of the material transfer mechanism 4, the turntable 23 of the rolling mechanism 2, the first cutter 63 of the cutting mechanism 6, and the second cutter 731 of the milling and turning device 73 are replaced. Simultaneously, the processing parameters are reset through the central control system. After the adjustment is completed, the processing of the new specification material 200 can be started. The entire process does not require equipment replacement; different needs can be quickly adapted through simple adjustments, achieving flexible production.

[0044] As stated above, this case protects an automatic metal rod milling machine, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
