Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a high-precision fully automated CNC machine tool. Background Technology

[0002] Currently in the field of mechanical manufacturing, round rod parts are core basic components for industries such as automobiles, aerospace, construction machinery, and home appliances. Their processing quality directly determines the operational stability, transmission accuracy, and service life of the entire equipment. As the manufacturing industry transforms towards intelligence, efficiency, and high precision, the market demand for round rod parts continues to grow. Simultaneously, more stringent requirements are being placed on the dimensional tolerances, geometric tolerances, and surface roughness of these parts. Traditional processing methods are gradually becoming inadequate for the current industry development needs. The processing of round rod parts generally adopts a traditional model of multi-process decomposition and multi-equipment collaboration. This means that, based on the part's processing technology, the complete processing flow is broken down into 3-5 independent processes, each corresponding to a dedicated processing machine. Taking a cylindrical transmission rod requiring a center hole as an example, its processing flow requires the following steps: a bar cutting machine to cut long raw materials into rough blanks of a preset length; a conventional lathe to rough and finish turn the outer diameter of the blank to ensure the accuracy of the outer diameter; a vertical drilling machine to manually clamp and fix the semi-finished product, drilling the center holes at both ends; a grinding machine to grind the key outer cylindrical surfaces; and for some complex parts, milling machines, tapping machines, and other equipment are needed to further extend the process chain. This traditional processing model suffers from three core problems that severely restrict production efficiency and processing quality. First, it occupies a large area and has low space utilization. Each specialized piece of equipment requires independent installation space, and at least 0.8 to 1.2 meters of operating aisle and parts transfer space must be reserved between equipment. For small and medium-sized manufacturing enterprises, the limited workshop area often can only accommodate 2 to 3 incomplete processing lines. This not only limits the expansion of production scale but may also restrict operator movement due to the compact equipment layout, increasing the risk of mechanical injury. Second, it has a high dependence on manual labor and rising production costs. The transfer of parts between processes relies entirely on manual labor. Enterprises need to allocate dedicated personnel to handle semi-finished products, loading and unloading materials, and coordinating processes between equipment. For example, a production line producing 500 round rod parts per day requires at least 3-4 workers operating in shifts, resulting in a high proportion of labor costs. Furthermore,... Manual transfer has an unavoidable efficiency bottleneck. After the previous process is completed, the parts need to wait for workers to move them to the next machine. Each transfer takes about 1 to 2 minutes. If the equipment is scattered in the workshop, the transfer time can be extended to 3 to 5 minutes. This results in the waiting time between processes being extended as a percentage of the total production cycle time, and the overall processing efficiency is greatly reduced. Thirdly, the processing accuracy is easily affected and the scrap rate is high. During manual transfer, the outer surface of the parts is easily scratched or deformed due to collisions and vibrations. Especially for semi-finished products that have been precision turned, surface damage directly leads to the scrapping of the parts. More importantly, the clamping and positioning benchmarks of each machine are different. When manually transferring the parts from the lathe to the drilling machine, it is difficult to ensure the coaxiality of the part axis and the drilling machine spindle. This can easily cause the center hole position to deviate. During subsequent assembly, it is impossible to accurately match the bushing, requiring rework or direct scrapping, which significantly increases production costs. Currently, the processing of round rod parts requires dividing the entire process into multiple steps, each using different processing equipment, which occupies a large area. After each step is completed, workers need to transport the parts to the next piece of equipment, resulting in high labor costs. Although some companies have tried to introduce semi-automated equipment in recent years, such equipment can only automate a single process and cannot integrate multiple processing steps. The transfer between processes still requires manual intervention, failing to fundamentally solve the pain points of multiple equipment, high labor costs, and low precision. The industry urgently needs a high-precision processing equipment that can integrate multiple core processing steps of round rod parts and automate the entire process from raw material feeding to finished product collection, in order to break through existing technological bottlenecks and meet the urgent needs of the manufacturing industry for efficient, high-precision, and low-cost processing of round rod parts. To address the aforementioned issues, this application proposes a high-precision, fully automated CNC machine tool. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-precision fully automated CNC machine tool, which solves the problems of large footprint, low space utilization, high reliance on manual labor leading to rising production costs, and high scrap rate due to susceptibility to processing accuracy issues.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a high-precision fully automated CNC machine tool, comprising a machine tool, a housing, and a feeding device. The upper surface of the machine tool is fixedly connected to the housing. The feeding device is located at the feed inlet of the housing. The feeding device includes a first rotating rod, an upper pressure roller, a second rotating rod, and a lower pressure roller. The side surface of the first rotating rod is fixedly connected to the upper pressure roller, and the side surface of the second rotating rod is fixedly connected to the lower pressure roller. A bracket is fixedly connected to the upper surface of the machine tool, and the side surfaces of the first and second rotating rods are rotatably connected to the bracket. The outer casing is internally equipped with a fixing device, a drilling device, and a cutting device. The fixing device includes a bevel ring, a first bevel gear, and a threaded rod. The outer surface of the bevel ring is rotatably connected to the outer casing. The side surface of the first bevel gear meshes with the bevel ring. The inner wall of the first bevel gear is threadedly connected to the threaded rod. There are three first bevel gears and three threaded rods arranged in a circular array.

The upper end of the second hydraulic cylinder is fixedly connected to the L-shaped frame. The inner wall of the L-shaped frame is fixedly connected to the cutting machine.

[0005] By adopting the above technical solution, the fixing device clamps the round rod, the drilling device drills holes in it, and after the processing is completed, the cutting device cuts off the workpiece.

[0006] Preferably, a drive device is installed on the bracket. The drive device includes a first motor, a first gear, and a second gear. The first motor is installed on the outside of the bracket. The output end of the first motor is fixedly connected to a first rotating rod. The side surface of the first rotating rod is fixedly connected to the first gear. The side surface of the second rotating rod is fixedly connected to the second gear. The side surface of the first gear is meshed with the second gear.

[0007] By adopting the above technical solution and setting up a drive device, the No. 1 motor drives the No. 1 gear on the No. 1 rotating rod to rotate, causing the No. 2 gear meshing with it to rotate in turn. This causes the round rod to be squeezed and clamped as it passes between the upper and lower pressure rollers and conveyed to the feed inlet, replacing the traditional manual feeding and thus improving the feeding efficiency.

[0008] Preferably, the outer end of the first rotating rod is provided with a cleaning device, which includes an eccentric rod, a connecting rod, a fixed rod, and a wiping sleeve. One end of the eccentric rod is fixedly connected to the first rotating rod, and the end of the eccentric rod away from the first rotating rod is rotatably connected to the connecting rod. The end of the connecting rod away from the eccentric rod is hinged to the fixed rod. The side surface of the fixed rod is fixedly connected to the wiping sleeve. The two ends of the fixed rod are hinged to a first slider. The side surface of the first slider is slidably connected to a limit frame, and the outer end of the limit frame is fixedly connected to the outer shell.

[0009] By adopting the above technical solution and setting up a cleaning device, when the feeding device is running, the No. 1 rotating rod is in a rotating state, which drives the eccentric rod to rotate. The outer end of the eccentric rod drives the connecting rod to push and pull the fixed rod back and forth. The No. 1 slider at both ends of the fixed rod slides back and forth along the predetermined track of the limit frame, thereby realizing that the fixed rod drives the wiping sleeve to slide back and forth in the horizontal direction. When the round rod passes through the wiping sleeve, the sponge or cloth set in the inner ring of the wiping sleeve is used to wipe the side surface of the round rod back and forth, so that the round rod that enters the outer shell for processing remains clean.

[0010] Preferably, a second motor, a fixing member, and a sliding bracket are fixedly connected to the left inner wall of the outer casing. A second bevel gear is fixedly connected to the output end of the second motor. The side surface of the second bevel gear meshes with a bevel gear ring. The interior of the fixing member is rotatably connected to a first bevel gear. The end of the threaded rod away from the fixing member is slidably connected to the sliding bracket. There are three fixing members and three sliding brackets, which are arranged in a circular array.

[0011] By adopting the above technical solution, a second motor is set up, which drives the second bevel gear to rotate. The second bevel gear drives the bevel ring to rotate on the inner wall of the outer shell. The bevel ring drives the first rotating rod and the first bevel gear to rotate. The threaded rod connected to the internal thread of the first bevel gear extends and retracts synchronously, thereby achieving multi-directional clamping and fixing of the round rod.

[0012] Preferably, the machine tool is equipped with a discharge device, which includes a discharge hopper, a second slider, a guide rod, and a spring. The lower surface of the discharge hopper is fixedly connected to the second slider, the inner wall of the second slider is slidably connected to the guide rod, the guide rod passes through the inside of the spring, one end of the spring is fixedly connected to the second slider, the other end of the spring is fixedly connected to the machine tool, a stop block is fixedly connected to the side surface of the L-shaped frame, a stop plate is fixedly connected to the left side of the discharge hopper, and the lower surface of the stop block is in contact with the stop plate.

[0013] By adopting the above technical solution and setting up a discharge device, when the L-shaped frame descends with the No. 2 hydraulic cylinder, it will drive the abutment block to squeeze the abutment plate. The abutment plate will push the discharge hopper to slide directly below the round rod, so that the round rod to be cut falls into the discharge hopper. After the cutting is completed, the abutment block rises with the L-shaped frame, and the discharge hopper is pulled back by the spring, thereby sending out the processed round rod.

[0014] Preferably, the upper surface of the machine tool is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the second slider.

[0015] By adopting the above technical solution and setting up a chute, the second slider can slide back and forth along the chute, thereby continuously transporting materials and improving efficiency.

[0016] Preferably, the outer shell has a discharge port, a conveyor belt is provided below the discharge port, and a receiving hopper is provided at the right end of the conveyor belt.

[0017] By adopting the above technical solution and setting up a discharge port, the discharge hopper transports the material from the inside of the outer shell through the discharge port and onto the conveyor belt. The conveyor belt then transports the material to the receiving hopper for collection, which greatly improves the material collection efficiency compared to traditional manual material collection.

[0018] (III) Beneficial Effects In summary, this application includes at least one of the following beneficial technical effects: 1. A high-precision fully automated CNC machine tool, in which the first motor in the feeding device drives the first rotating rod to rotate, not only causing the first gear and the second gear to mesh, making the upper and lower pressure rollers squeeze the conveying round rod, but also simultaneously driving the eccentric rod of the cleaning device to rotate. The eccentric rod pushes and pulls the fixed rod through the connecting rod, causing the first slider at both ends of the fixed rod to slide back and forth along the limit frame, thereby causing the wiping sleeve to horizontally and reciprocally wipe the round rod that passes through. This design does not require an additional power source, which not only replaces the traditional manual feeding to improve feeding efficiency, but also removes impurities from the surface of the round rod through real-time cleaning, avoiding the impurities from affecting the subsequent processing accuracy. It solves the traditional drawbacks of separate feeding and cleaning operations. Through the mechanical linkage between the feeding device and the cleaning device, the effect of simultaneous feeding and raw material cleaning is achieved.

[0019] 2. A high-precision fully automated CNC machine tool, in which the L-shaped frame is lowered by the second hydraulic cylinder in the cutting device, not only brings the cutting machine close to the round rod to complete the cutting, but also the abutment block on the L-shaped frame squeezes the abutment plate of the discharge device. The abutment plate pushes the discharge hopper to slide along the slide groove with the second slider to the cutting position to receive the material. After the cutting is completed, the L-shaped frame rises, and the discharge hopper is reset under the tension of the spring, sending the finished product through the discharge port of the outer shell to the conveyor belt, and finally falling into the receiving hopper. This design eliminates the need for manual intervention in material receiving, achieving seamless connection between cutting, receiving, and conveying, replacing traditional manual material receiving. At the same time, the discharge hopper is automatically reset by the spring, and with the continuous conveying of the conveyor belt, the efficiency of finished product processing is greatly improved, realizing the integrated effect of cutting and automatic conveying of finished products.

By setting up the drive device, the first motor 8 drives the first gear 9 on the first rotating rod 3 to rotate, causing the meshing second gear 10 to rotate successively. This causes the round rod to be squeezed and clamped when passing between the upper pressure roller 4 and the lower pressure roller 6 and conveyed to the feed inlet, replacing the traditional manual feeding and thus improving the feeding efficiency. A cleaning device is set at the outer end of the first rotating rod 3. The cleaning device includes an eccentric rod 11, a connecting rod 12, a fixed rod 13, and a wiping sleeve 14.

The first slider 15 at both ends of the fixed rod 13 slides back and forth along the predetermined track of the limit frame 16, thereby realizing that the fixed rod 13 drives the wiping sleeve 14 to slide back and forth in the horizontal direction. When the round rod passes through the wiping sleeve 14, the sponge or cloth set in the inner ring of the wiping sleeve 14 is used to wipe the side surface of the round rod back and forth, so that the round rod processed inside the outer shell 2 remains clean.

[0027] Reference Figure 1 , Figure 2, Figure 4 and Figure 6 The machine tool 1 is equipped with a discharge device, which includes a discharge hopper 29, a second slider 30, a guide rod 31, and a spring 32. The lower surface of the discharge hopper 29 is fixedly connected to the second slider 30, and the inner wall of the second slider 30 is slidably connected to the guide rod 31.

The stop plate 34 pushes the discharge hopper 29 to slide directly below the round rod, so that the cut round rod falls into the discharge hopper. In the discharge hopper 29, after cutting, the abutment block 33 rises with the L-shaped frame 27, and the discharge hopper 29 is pulled back by the spring 32, thereby sending out the processed round rod.

[0028] The implementation principle of this invention is as follows: When the first motor 8 of the driving device is energized, its output end drives the first rotating rod 3 to rotate. The first gear 9 on the first rotating rod 3 meshes with the second gear 10 on the second rotating rod 5, causing the second rotating rod 5 to rotate in the opposite direction. This causes the upper pressure roller 4 of the first rotating rod 3 and the lower pressure roller 6 of the second rotating rod 5 to rotate in the opposite direction. The round rod is squeezed by the two pressure rollers and conveyed to the feed port of the outer shell 2. At the same time, the eccentric rod 11 at the outer end of the first rotating rod 3 rotates with the rotating rod, and pushes and pulls the fixed rod 13 through the connecting rod 12. The first slider 15 at both ends of the fixed rod 13 moves along... The limiting bracket 16 slides, causing the wiping sleeve 14 to reciprocate horizontally. When the round rod passes through the wiping sleeve 14, the sponge or mesh inside wipes away surface impurities, ensuring the cleanliness of the raw material. After the clean round rod enters the outer shell 2, the second motor 20 starts, and its output drives the second bevel gear 21 to rotate. The second bevel gear 21 meshes with the bevel gear ring 17, driving the bevel gear ring 17 to rotate on the inner wall of the outer shell 2. The bevel gear ring 17 simultaneously drives the three annularly distributed first bevel gears 18 to rotate. Under the guidance of the limiting bracket 23, the threaded rod 19 on the inner wall of the first bevel gear 18 moves synchronously towards the center. The telescopic mechanism clamps the round rod from three directions to prevent it from shifting during processing. After the raw material is fixed, the first hydraulic cylinder 24 of the drilling device is energized, pushing the electric drill 25 close to the round rod. The electric drill 25 starts drilling, and after completion, the first hydraulic cylinder 24 resets. During the cutting stage, the second hydraulic cylinder 26 is energized, causing the L-shaped frame 27 to descend. The cutting machine 28 on the L-shaped frame 27 moves down and starts cutting the round rod. At the same time, the abutment block 33 of the L-shaped frame 27 presses against the abutment plate 34 of the discharge hopper 29, pushing the discharge hopper 29 to slide along the slide groove 35 and guide rod 31 of the machine tool 1 through the second slider 30 until the discharge hopper 29... 9. Move to directly below the round rod. After cutting, the piston rod of the second hydraulic cylinder 26 retracts, the L-shaped frame 27 rises, the stop block 33 rises accordingly, the spring 32 outside the guide rod 31 resets, pulling the second slider 30 to drive the discharge hopper 29 to reset, the finished product is sent out through the discharge port 36 of the outer shell 2 and falls into the lower conveyor belt 37, and is finally conveyed to the receiving hopper 38 for collection. The whole process does not require manual intervention, which greatly improves production efficiency and solves the problems of large footprint, low space utilization, high dependence on manual labor, rising production costs, and high scrap rate that are easily affected by processing accuracy.
