Description

Technical Field

[0001] This invention relates to the field of loading and unloading machines, specifically to a loading and unloading machine for an engine intake valve body lathe. Background Technology

[0002] The engine intake valve is a core component of the engine intake system. The machining precision and surface quality of its valve body directly determine the engine's intake efficiency and operational stability, which is crucial to the vehicle's power. The initial product of the intake valve body is a cast or forged blank. Due to process limitations, these blanks generally have problems such as low dimensional accuracy and poor surface quality. Specifically, they have oxide scale on the surface, burrs on the edges and corners, and large dimensional deviations on key mating surfaces. They cannot be directly assembled and must be machined using equipment such as lathes to remove oxide scale and burrs, and turn key surfaces to achieve the required precision and control dimensional tolerances to ensure compatibility with the valve seat and valve core.

[0003] In the existing processing flow, the removal of burrs and oxide scale from blanks, as well as the inspection of flatness, largely rely on manual labor: burrs and oxide scale are removed by manual grinding, followed by manual inspection of flatness. This method is time-consuming, labor-intensive, inefficient, and lacks consistency, easily leading to incomplete burr removal and large inspection errors, affecting the accuracy of subsequent lathe machining. Furthermore, the process connections are cumbersome, and manual handling of workpieces is prone to damage from bumps and knocks, severely restricting the automation level and production efficiency of the production line, and failing to meet the demands of high-volume, high-precision production. Furthermore, although integrated processing is not present in existing technologies, relatively stable hydraulically driven grippers are used for auxiliary operations to reduce manual labor intensity. However, existing hydraulically driven grippers still have many drawbacks and fail to adequately meet the processing requirements of intake valve bodies. Specific defects are as follows: First, loading and unloading machines mostly use a single gripper to complete the clamping operation of blanks and smooth finished parts. Due to the burrs on the surface of the blanks, the burrs will directly scratch the clamping surface of the gripper during the clamping process. After long-term use, the wear of the clamping surface of the gripper will intensify, resulting in a decrease in clamping accuracy and seriously affecting the stability of subsequent gripping. For smooth finished parts that have undergone grinding, their smooth surface and low friction make them prone to slippage during clamping, affecting the stability of workpiece transfer. Secondly, in existing technologies, to avoid the aforementioned slippage and scratching problems, the basic clamping pressure of the grippers is often changed by adjusting the hydraulic system. That is, the pressure is increased when clamping blanks and decreased when clamping finished parts. However, during long-term continuous operation, the hydraulic system is affected by factors such as oil compressibility, oil circuit damping, oil temperature changes and component wear, which can lead to slow response and delayed action. Moreover, relying solely on oil pressure to maintain pressure depends on the hydraulic valve group, and the pressure is prone to fluctuation, which can cause the grippers to loosen slightly and the workpiece to slip and fall. This not only fails to fundamentally solve the slippage and scratching problems, but also increases the complexity of hydraulic system control, and increases the equipment failure rate and maintenance costs. More importantly, during the actual operation of hydraulic grippers, continuous gripping / releasing actions are required. If the hydraulic system malfunctions due to PLC dead loops, pump valve jamming, or delayed oil pressurization control, the grippers may be forced to over-clamp due to continuous pressure application. This results in static compression between the workpiece (intake valve body) and the grippers. Under static compression, mechanical damage such as valve body deformation, surface scratches, local cracking, gripper bending, permanent deformation, and even root fracture can occur. These situations not only lead to batch scrapping of workpieces and gripper failure, but also seriously affect the positioning accuracy and operational reliability of subsequent loading and unloading operations, causing problems such as lathe machining deviations, station interference, and equipment jamming, further restricting production efficiency and increasing production costs.

[0004] In summary, there is an urgent need for an engine intake valve body lathe loading and unloading machine that can integrate loading and unloading, adapt to two workpiece shapes, effectively avoid mechanical damage caused by hydraulic system miscontrol and pressurization lag, and improve work efficiency, stability and machining accuracy. This is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, an engine intake valve body lathe loading and unloading machine is proposed to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an engine intake valve body lathe loading and unloading machine, comprising: a workpiece, and further comprising: a first component; The first component includes an instrument cabinet, a machine tool is provided on one side of the instrument cabinet, and a vibrating feeding device, a feeding hopper, a picking plate, a storage tray, a detection driver, a placement table and a robotic arm are provided inside the instrument cabinet. The material picking plate, detection driver, placement platform, and storage tray are arranged in sequence, and the robotic arm is located in the inner cavity of the instrument cabinet and fixed to the side close to the processing machine tool. The detection driver is equipped with a contact bias probe.

[0007] As a preferred option, a second component is also included; The second component includes a horizontal plate disposed at the end of the robotic arm, an air gun component disposed on the horizontal plate, the air gun component being connected to an external air pump via an air pipe, and grippers symmetrically fixedly connected to the horizontal plate; Both of the grippers are vertically provided with sliding grooves, and disc springs are fixedly connected to the inner walls of both sliding grooves at equal intervals.

[0008] Preferably, a serrated anti-slip toothed plate is slidably connected in one of the sliding grooves, and a buffer pad is slidably connected in another of the sliding grooves, the buffer pad being made of rubber.

[0009] As a preferred option, a third component is also included; The third component includes an oil pipe disposed on the side wall of the horizontal plate. One end of the oil pipe is connected to an external oil pump body, and the other end is inserted and fixed to one of the valve ports of a three-way valve. A three-way valve is fixedly connected to the side wall of the horizontal plate, and a transmission pipe is inserted and fixed inside the valve port of the three-way valve. The oil pipe and the transmission pipe are on the same straight line. The three-way valve contains a ball. A pressure relief bladder is fixedly connected to the valve port of the three-way valve by screws, and the inner cavity of the pressure relief bladder is connected to the inner cavity of the three-way valve.

[0010] Preferably, the detection driver, the placement stage, and the contact bias probe constitute a flatness detection device.

[0011] Preferably, the serrated anti-slip plate and the buffer pad are slidably fitted and installed inside the sliding groove; and the sum of the thickness of any two plates after sliding into the sliding groove and the thickness of the disc spring in the uncompressed state is equal to the opening width of the sliding groove.

[0012] Preferably, the sphere has three openings that are interconnected.

[0013] Preferably, the ball exists in three position states within the three-way valve; State 1: none of the three ports are connected to the inlet direction of the oil pipe; State 2: two of the ports are on the same straight line as the oil pipe and the transfer pipe, and the last port is attached to the inner wall of the three-way valve; State 3: half of one port is connected to the delivery direction of the oil pipe, and the other half is connected to the direction of the pressure relief bladder.

[0014] Compared with the prior art, the present invention provides an engine intake valve body lathe loading and unloading machine, which has the following beneficial effects: 1. This invention, through its integrated design, offers the following advantages compared to the manual operation mode in existing technologies: This design achieves fully integrated operation, significantly improving work efficiency: It integrates loading and unloading operations with valve body burr and oxide scale removal, surface finishing, and precision inspection into one process, linking various related equipment to form an automated production line. This replaces the traditional mode of manual grinding to remove burrs and oxide scale, followed by manual flatness inspection, avoiding the tedious process of manual operation, effectively reducing labor input and labor intensity. At the same time, the integrated operation reduces the gap between processes, avoids the time-consuming manual transfer of workpieces, and significantly improves overall work efficiency, making it suitable for the needs of large-volume valve body processing. Improving the smoothness of process connections and reducing the risk of workpiece damage: In existing technologies, manual handling of the connection between processes is cumbersome, and manual transfer of workpieces is prone to collisions and scratches, affecting the accuracy of subsequent processing; This integrated design achieves seamless connection between the processes of loading, deburring, surface finishing, inspection, and unloading through automated linkage control, eliminating the need for manual intervention in transfer, effectively avoiding collisions and damage to workpieces during transfer, ensuring the surface quality and structural integrity of the valve body, and providing a guarantee for the accuracy of subsequent processing.

[0015] 2. The present invention, through the synergistic design of the double grippers, serrated anti-slip plate, and rubber buffer pad in the second component, can bring the following benefits: To achieve precise adaptation between two workpiece shapes and improve clamping stability and reliability: This design uses dual jaws to correspond to burred blanks and smooth finished parts respectively, avoiding the adaptation contradictions caused by a single jaw handling both types of workpieces. The serrated anti-slip toothed plate on the clamping side of the finished workpiece can effectively increase the friction with the smooth surface of the finished part, solving the slippage problem caused by the smooth surface and insufficient friction of the finished part, ensuring the stability and non-deviation of the finished part during loading and unloading. The wear-resistant hard rubber buffer pad on the clamping side of the blank can actively avoid surface burrs when clamping the blank, while dispersing the clamping stress and preventing excessive force on a single point from crushing the edge of the blank. This not only ensures the stability of the blank clamping but also prevents burrs from directly scratching the jaws and extends the service life of the jaws. Adapting to automated loading and unloading requirements, improving operational efficiency and adaptability: Based on the first component, a dual-gripper design is adopted, which can work with the robotic arm to realize the continuous operation of loading blanks and unloading finished parts without manual intervention to switch gripping structures. It is suitable for the needs of large-volume, automated processing of engine intake valve bodies. At the same time, the structural design is simple and can be flexibly integrated into existing lathe loading and unloading machines without major modifications to the equipment. It has strong adaptability and further improves the automation level and operational efficiency of the entire production line.

[0016] 3. This invention, through the design of a third component, specifically optimizes the hydraulic gripper operation process, bringing the following benefits: Effectively avoids mechanical damage and reduces workpiece scrap rate and gripper wear: The third component can solve the problem of excessive clamping between the workpiece and the gripper in hydraulic dual-gripper operation. Through active isolation and passive pressure relief bladder diversion and transfer, combined with the design of the pressure relief valve, it prevents the gripper on the clamping side from being forced to over-clamp due to the hydraulic system's mis-control of continuous pressure clamping or the lag of oil pressure control. This avoids mechanical damage such as deformation, surface damage, local cracking, as well as gripper bending, permanent deformation, and even root fracture caused by static extrusion on the intake valve body and gripper. It significantly reduces the risk of batch workpiece scrapping, reduces the frequency of gripper maintenance and replacement, and reduces equipment wear and production costs. Ensuring the positioning accuracy of the entire machine for loading and unloading, and improving operational reliability: It avoids the adverse effects of workpiece and gripper damage on subsequent operations, effectively prevents loading and unloading positioning deviations caused by workpiece deformation and decreased gripper accuracy, avoids problems such as lathe machining deviations, station interference, and equipment jamming caused by inaccurate positioning, ensures continuous and stable operation of the entire machine for loading and unloading, improves equipment operational reliability, and ensures smooth operation of the production line. Improve the safety of hydraulic dual-gripper operation and reduce the risk of equipment failure: The third component does not rely on complex hydraulic system control or electronic control intervention. Based on the disc spring, it avoids the safety hazards caused by hydraulic system miscontrol and pressure lag through the protection of the mechanical structure itself, reduces equipment downtime for maintenance due to mechanical damage, reduces equipment failure rate, ensures the continuity and safety of industrial production, and is suitable for the large-scale, high-precision automated processing needs of engine intake valve bodies.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] Example Please refer to Figures 1 to 6 As shown: To address the problems mentioned in the technical solutions, this application provides an engine intake valve body lathe loading and unloading machine, including: workpiece 1, and further including: a first component; the first component includes an instrument cabinet 201, a machine tool 202 is arranged on one side of the instrument cabinet 201, and a vibratory loading device 203, a unloading hopper 204, a picking plate 205, a storage tray 206, a detection driver 207, a placement table 208, and a robotic arm 210 are arranged in sequence; the picking plate 205, the detection driver 207, the placement table 208, and the storage tray 206 are located in the inner cavity of the instrument cabinet 201 and fixed to the side near the machine tool 202; a contact bias probe 209 is arranged on the detection driver 207.

[0022] in: The first component is used to integrate the loading and unloading operations of workpiece 1, namely the engine intake valve body, so that the burrs and oxide scale are removed by the processing machine tool 202 and other equipment, so that the surface can achieve the precision process requirements of smoothness and flatness. This is different from the existing technology where burrs and oxide scale are manually removed and then the flatness is checked, which is time-consuming, labor-intensive and the connection between each process is also very troublesome.

[0023] The machining tool 202 is used to perform surface treatment on the blank workpiece 1 to ensure its subsequent installation accuracy requirements.

[0024] The detection driver 207, the placement stage 208, and the contact bias probe 209 constitute the flatness detection device for the workpiece 1. In use, the cylinder inside the detection driver 207 moves the contact bias probe 209 downward with the assistance of the guide rail. The contact bias probe 209 will eventually come into contact with the workpiece 1 on the placement stage 208. At this time, the contact bias probe 209 will perform flatness detection on the processed workpiece 1.

[0025] The overall operation of the loading and unloading machine is roughly as follows: the blank workpiece 1 is loaded by the vibrating loading device 203 → the processing machine tool 202 processes it → the detection driver 207 and the placement table 208 cooperate to detect the processed workpiece 1 → unloading; in the above process, the robotic arm 210 is used for the workpiece 1 to pick up, unload and transfer its position.

[0026] A further embodiment: Please refer to Figure 2 , Figure 4 , Figure 8 As shown: The second component includes a horizontal plate 301 disposed at the end of the robotic arm 210. An air gun 302 is disposed on the horizontal plate 301 and is connected to an external air pump through an air pipe. Grippers 303 are symmetrically fixedly connected to the horizontal plate 301. Each of the two grippers 303 has a vertically opened sliding groove 304. Disc springs 305 are fixedly connected at equal intervals to the inner walls of the two sliding grooves 304. A serrated anti-slip toothed plate 306 is slidably connected in the sliding groove 304. A buffer pad 307 is slidably connected in the other sliding groove 304.

[0027] in: The second component is used to adapt to two different workpiece states 1 when the robotic arm 210 indirectly drives the workpiece 1 for loading and unloading operations: one with burrs and the other with a smooth finished product state after grinding. It can specifically avoid the problem of burrs scratching the gripper 303 when holding the workpiece with a single gripper 303, which affects the stability of the equipment operation in the long term. At the same time, it solves the defect of easy slippage when holding smooth finished parts due to the smooth surface. It does not need to rely on the adjustment of the hydraulic system clamping pressure, and avoids the drawbacks of valve group pressure fluctuation, slight loosening of the gripper 303, slippage and falling of the workpiece 1 caused by oil pressure holding, as well as the disadvantages of hydraulic response lag and complex control process. It realizes stable adaptation and reliable loading and unloading of workpiece 1 in two different states.

[0028] The air gun 302 is connected to an external air pump via an air pipe and is used to clean the workpiece 1 and related equipment parts that come into contact with it before and after placement, thereby reducing the interference of external factors such as dust and debris on the overall process during loading and unloading.

[0029] Two grippers 303 are symmetrically arranged on the horizontal plate 301, and each set of grippers 303 corresponds to a hydraulic system. Except for the serrated anti-slip toothed plate 306 and buffer pad 307 that are slidably installed in the sliding groove 304, the working process of the two is the same. This design only describes one of them.

[0030] The serrated anti-slip plate 306 and the buffer pad 307 are both slidably fitted and installed inside the sliding groove 304; and the sum of the thickness of any two plates after sliding into the sliding groove 304 and the thickness of the disc spring 305 in the uncompressed state is equal to the opening width of the sliding groove 304.

[0031] The finished workpiece 1 is clamped on the gripper 303 with a serrated anti-slip tooth plate 306. When clamping a smooth finished workpiece, the anti-slip tooth plate increases the friction and prevents the workpiece 1 from slipping.

[0032] The buffer pad 307 can be made of rubber. A wear-resistant hard rubber buffer pad 307 is slidably installed on the jaws 303 on the clamping side of the blank workpiece 1. When clamping the blank workpiece, the hard buffer pad avoids burrs, disperses clamping stress, avoids single-point force to crush the edge of the blank, and at the same time prevents burrs from scratching the jaws 303.

[0033] Both of the above-mentioned grippers 303 and disc springs 305 work together during operation. Depending on the specific situation, serrated anti-slip toothed plates 306 and buffer pads 307 of different thicknesses can be replaced. By replacing the pressure-adjusting disc springs 305 of different thicknesses, the clamping force can be mechanically adjusted. In the event of hydraulic system miscontrol / control pressure lag, it can also assist in the corresponding clamping work of blanks and finished parts. There is no need to adjust the hydraulic system pressure according to the usage time and cycle of the hydraulic system (the loading and unloading operation is bound to be a periodic and long-term operation; hydraulic drive will have problems such as thick hydraulic oil and drive delay under long-term use). This simplifies the operation and avoids the risk of workpiece 1 being damaged or falling.

[0034] A further embodiment: Please refer to Figure 2 , Figure 7 , Figure 9 As shown: The third component includes an oil pipe 401 disposed on the side wall of the horizontal plate 301. One end of the oil pipe 401 is connected to an external oil pump body, and the other end is inserted and fixed to one of the valve ports of a three-way valve 402. The three-way valve 402 is fixedly connected to the side wall of the horizontal plate 301. A transmission pipe 403 is inserted and fixedly connected to the valve port of the three-way valve 402. The oil pipe 401 and the transmission pipe 403 are on the same straight line. A ball 405 is disposed inside the three-way valve 402. A pressure relief bladder 404 is fixedly connected to the valve port of the three-way valve 402 by screws. The inner cavity of the pressure relief bladder 404 is connected to the inner cavity of the three-way valve 402.

[0035] in: The third component is used to avoid mechanical damage such as deformation, crushing, cracking, or even breakage of the workpiece 1 / valve body and the gripper 303 when the workpiece 1 is clamped by a single gripper 303 and the other gripper 303 is unloaded, due to the hydraulic system's miscontrol of continuous pressure clamping or the lag in oil pressure control. At the same time, it is used to avoid the workpiece 1 / valve body and the gripper 303 being affected by static extrusion during the operation of the hydraulic double gripper 303.

[0036] One end of the oil pipe 401 is connected to the external oil pump body, and the other end is connected to the three-way valve 402.

[0037] The three-way valve 402 has three ports that are respectively connected to the oil pipe 401, the transmission pipe 403, and the pressure relief bladder 404.

[0038] The pressure relief bladder 404 is used for oil transfer and storage when the non-driven gripper 303 is in operation.

[0039] The ball 405 has three ports that are interconnected; the ball 405 has three position states within the three-way valve 402. State 1: Oil delivery state. Control ball 405 rotates 90 degrees counterclockwise. At this time, two of the ports are on the same straight line as oil pipe 401 and transmission pipe 403. The port that originally faced the pressure relief bladder 404 is blocked by the inner wall of three-way valve 402. At this time, oil pipe 401 can deliver oil to transmission pipe 403 through three-way valve 402. The above state is opened when any gripper 303 is initially controlled by the hydraulic system to retract. This action is before state 2. State 2: Active blocking state, please refer to the appendix. Figure 9 As shown, none of the three ports are connected to the inlet direction of the oil pipe 401 at this time. At this time, the oil pipe 401 cannot deliver oil to the transfer pipe 403 through the three-way valve 402. Regardless of whether the system mis-controls the hydraulic oil transfer / control lag causes the gripper 303 to further perform a clamping action, due to its active blocking, the hydraulic oil in the pipes on both sides of the ball 405 is relatively stable (the pipe where the oil pipe 401 is located has a pressure relief valve to achieve oil stability; the oil in the transfer pipe 403 associated with the gripper 303 is stable and unchanged, and the clamping force of the gripper 303 remains unchanged). The above state is followed by the device's main controller after each time the hydraulic system controls any gripper 303 to clamp. State 3: Hydraulic system miscontrol (the gripper 303 should not be clamping the oil, but it is) / Oil pressurization control lag state. At this time, the main controller of the device will control the drive to drive the ball 405, which is not in operation, to rotate 45 degrees clockwise through the valve stem. At this time, half of one of the ports is connected to the oil pipe 401 in the direction of delivery, and the other half is connected to the pressure relief bladder 404. If the oil continues to be delivered, the inner cavity of the pressure relief bladder 404 will carry the oil storage work.

[0040] All of the above-mentioned electronic control components are electrically connected to the main controller of the device and are controlled by it in a coordinated manner.

[0041] The working principle of all the content in the above embodiments is as follows: The engine intake valve body lathe loading and unloading machine uses the first component as the core integrated platform, works with the second component to complete dual-mode workpiece clamping, and the third component to realize hydraulic overload protection. It operates automatically in the entire process of loading → processing → inspection → unloading. The specific steps are as follows: Automatic blank feeding: Vibrating feeding device 203 sends out blank workpiece 1 in an orderly manner, and robotic arm 210 drives the second component to move to the material picking position to prepare to grab the blank workpiece.

[0042] Stable clamping of blanks: The horizontal plate 301 at the end of the robotic arm 210 drives the gripper 303 to move. The gripper 303 with rubber buffer pad 307 clamps the blank. The buffer pad 307 avoids burrs and disperses stress. It works with disc spring 305 to buffer and prevent burrs from scratching the gripper 303, while ensuring stable clamping.

[0043] Finished part switching clamping and blank part surface machining: The robotic arm 210 moves the blank part to the machining machine 202; then, the existing servo flipping component at the front end of the robotic arm 210 drives the horizontal plate 310 to move, and the gripper 303 with serrated anti-slip toothed plate 306 clamps the smooth finished part processed in the previous processing cycle, and the air gun component 302 assists in blowing away the processing debris; after the finished part of the previous cycle is removed, the robotic arm 210 then controls the gripper 303 with rubber buffer pad 307 through the servo flipping component to transport the blank part to the machining machine 202, and makes it perform deburring and other surface finishing on the workpiece 1; Automated flatness inspection: Further, the robotic arm 210 clamps and transfers the finished part to the placement table 208; the inspection driver 207 drives the contact bias probe 209 to move down through the cylinder, and abuts against the surface of the workpiece 1 to complete the flatness inspection and determine whether the workpiece 1 is qualified.

[0044] Hydraulic overload protection (third component coordination): During the clamping process, the oil enters the three-way valve 402 through the oil pipe 401, and the ball 405 is in the oil delivery state to ensure the normal drive of the gripper 303; furthermore, the device's main controller will switch to state one (active isolation state); if the hydraulic system is miscontrolled or the pressurization is delayed, the ball 405 switches to the hydraulic system's depressurization state, and excess oil flows into the depressurization bladder 404 to prevent the gripper 303 from excessively clamping and damaging the workpiece 1 and the gripper 303. In the above process, the disc spring 305 / buffer pad 307 also provides assistance.

[0045] Qualified finished products unloading and storage: Qualified workpiece 1 is transferred to storage tray 206 by robotic arm 210; unqualified workpiece 1 is transferred to unloading bin 204, completing automated sorting and unloading.

[0046] Cyclic operation: The above steps are linked and repeated to achieve uninterrupted automated operation of the entire process of engine intake valve body loading → processing → inspection → unloading.

[0047] Please refer to the above work process. Figures 1 to 9 .
