Description

Technical Field

[0001] This utility model relates to the field of boring machine technology, specifically a four-servo automatic cutting head boring machine. Background Technology

[0002] A boring machine is a specialized device for machining deep holes in hydraulic cylinders, air cylinders, and gas cylinders. It can also machine spindle holes, blind holes, and stepped holes for machine tools. It combines drilling, boring, and roll forming functions and can be applied in the fields of automobile manufacturing, aerospace, shipbuilding, and machinery manufacturing. The machine bed has high rigidity, good precision retention, and a wide spindle speed range. The feed system is driven by an AC servo motor and can adapt to the needs of various deep hole machining processes. The oil feeder is fastened and the workpiece is clamped by a hydraulic device. The instrument display is safe and reliable. The boring machine is also used to bore cylinder holes and cylinder liner inner holes of internal combustion engines such as automobiles and tractors, and can also be used for precision boring of inner holes of other mechanical parts.

[0003] Existing boring machines require operators to perform additional head-cutting on the workpiece after boring, which not only affects the dimensional accuracy and reduces consistency, but also increases workload and is not conducive to improving work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a four-servo automatic head-cutting boring machine to solve the problem mentioned in the background art that requires workers to perform additional head-cutting on the workpiece after boring, which not only affects the dimensional accuracy of the machining and reduces consistency, but also increases the workload and is not conducive to improving work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-servo automatic cutting head boring machine, including a support frame, a hydraulic oil tank and a hydraulic oil pump body installed at the lower part of the support frame, and the hydraulic oil tank is connected to the hydraulic oil pump body through an oil pipe. An upper protective cover is provided in the upper processing area of ​​the support frame. A feeding robot arm is provided on one side of the support frame. A feeding support frame is fixed on the side of the support frame near the feeding robot arm. A cross slide is provided on the worktable at the top of the support frame. A mold clamping arm is provided on the surface of the support frame for clamping the workpiece to be processed. A double-head power head and a boring power head are respectively installed on both sides of the worktable at the top of the support frame.

[0006] Preferably, the working range of the loading robotic arm covers the area above the feeding support and the cross slide.

[0007] By adopting the above technical solution, it is ensured that the workpiece can be accurately aligned with the feeding support and the cross slide, avoiding processing errors caused by loading misalignment. The adjustable clamping force structure breaks the limitation of gripping workpieces of a single specification, allowing the equipment to adapt to workpieces of different sizes and weights without frequent fixture changes, thus improving the flexibility of the equipment in processing different demonstration parts in automotive teaching. Preferably, the output end of the hydraulic pump body is connected to the mold clamping arm via a hydraulic pipeline to provide hydraulic power for the clamping action of the mold clamping arm.

[0008] By adopting the above technical solution, the cross slide is equipped with a servo motor drive, lubrication structure and limit components. The servo motor drive directly responds to the core characteristics of the equipment, "four servos", ensuring the displacement accuracy of the slide and providing a foundation for the precise machining of the dual-head power head and the boring power head.

[0009] Preferably, the machining axes of the dual-head power head and the boring power head are both adapted to the sliding direction of the cross slide, so as to realize the cutting and boring machining of the workpiece on the cross slide.

[0010] By adopting the above technical solution, heat dissipation components are added to the dual-head power head and the boring power head to specifically solve the problem of "overheating of the power head during long-term processing". The cooling fan accelerates airflow and the heat dissipation fins expand the heat dissipation area. The two work together to quickly remove the heat generated by the motor operation and prevent the power head from experiencing performance degradation due to high temperature.

[0011] Preferably, the cross slide is driven by a servo motor, and a lubricating oil pipe is provided on the sliding track of the cross slide.

[0012] By adopting the above technical solution, a safety sensing component is added to the inside of the upper protective cover and a transparent observation window is set on the outside. The safety sensing component is linked with the main control system. When the protective cover is not closed or a foreign object enters the processing area, it can immediately trigger an emergency stop, which makes up for the lack of basic protection of "only covering the processing area" and greatly reduces the risk of accidental contact by operators.

[0013] Preferably, both the dual-head power head and the boring power head are equipped with independent heat dissipation components. The heat dissipation components include a cooling fan and cooling fins. The cooling fan is installed on the outside of the housing of the dual-head power head and the boring power head, and the cooling fins are attached to the surface of the motor housing of the dual-head power head and the boring power head.

[0014] By adopting the above technical solution, a filter component is added to the hydraulic oil tank. The filter component can filter impurities in the hydraulic oil, prevent impurities from entering the hydraulic oil pump body and the hydraulic pipeline of the mold clamping arm, avoid pipeline blockage and component wear, ensure stable power supply of the hydraulic system, and ensure that the mold clamping arm can reliably clamp the workpiece.

[0015] Preferably, the hydraulic oil tank is equipped with a filter screen, and the bottom of the feeding support is equipped with a rubber buffer pad to reduce the impact generated when the workpiece is placed on the support.

[0016] By adopting the above technical solution, the workpiece is prevented from shifting during the feeding process, ensuring that the loading robot arm can accurately grasp it and avoid loading failure or processing deviation caused by workpiece shift. The shock absorption and buffer components can absorb the impact force when the workpiece is placed and protect the workpiece surface from damage.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This four-servo automatic head-cutting boring machine: 1. The equipment adopts four servo drive control core motion components. The loading robotic arm, equipped with a position detection component, can accurately grab the workpiece on the feeding support and place it on the cross slide. The cross slide is driven by a servo motor to achieve high-precision displacement. With the coordinated operation of the dual-head power head and the boring power head, the error caused by manual intervention is effectively reduced, and the dimensional accuracy and consistency of cutting and boring are improved. 2. In the hydraulic system, the hydraulic oil tank's filter assembly can purify the hydraulic oil, preventing impurities from clogging the pipeline and affecting the operation of the hydraulic oil pump body and the mold clamping arm; the safety sensing component inside the upper protective cover can trigger an emergency shutdown in abnormal situations such as the protective cover not being closed or foreign objects intruding; the heat dissipation component is a dual-head power head and a boring power head for cooling, comprehensively ensuring the long-term stable operation of the equipment and the safety of the operators. 3. The adjustable clamping structure of the loading robot arm can adapt to workpieces of different specifications. The guide and limiting structure of the feeding support frame prevents workpiece displacement, and the shock absorption and buffer components protect the workpiece surface. At the same time, the transparent observation window facilitates real-time observation of the processing status, and the oil level observation window and oil temperature detection element facilitate monitoring of the hydraulic system, meeting the needs of different parts processing demonstrations and practical teaching in the teaching field.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a four-servo automatic head-cutting and boring machine, including a support frame 1, a hydraulic oil tank 2, a hydraulic oil pump body 3, an upper protective cover 4, a loading robotic arm 5, a feeding support frame 6, a cross slide 7, a double-headed power head 8, a mold clamping arm 9, and a boring power head 10. The support frame 1 has a hydraulic oil tank 2 and a hydraulic oil pump body 3 installed at its lower part, and the hydraulic oil tank 2 is connected to the hydraulic oil pump body 3 via oil pipes. The working range of the loading robotic arm 5 covers the area above the feeding support frame 6 and the cross slide 7. The output end of the oil pump body 3 is connected to the mold clamping arm 9 through a hydraulic pipeline, providing hydraulic power for the clamping action of the mold clamping arm 9. The operator places the workpiece to be processed on the feeding support 6. The guide and limit structure of the feeding support 6 positions the workpiece. The loading robot arm 5 starts and provides real-time feedback of position information through the position detection component. The servo motor drives the rotating base and telescopic arm to move. The end clamping structure adjusts the clamping force according to the workpiece specifications. After grabbing the workpiece, it is moved to the top of the cross slide 7 and accurately placed on the surface of the mold clamping arm 9.

[0022] The upper processing area of ​​the support frame 1 is equipped with an upper protective cover 4. A loading robot arm 5 is installed on one side of the support frame 1. A feeding support frame 6 is fixed on the side of the support frame 1 near the loading robot arm 5. The processing axes of the double-headed power head 8 and the boring power head 10 are adapted to the sliding direction of the cross slide table 7, so as to realize the cutting and boring processing of the workpiece on the cross slide table. The cross slide table 7 is driven by a servo motor, and a lubricating oil pipe is installed on the sliding track of the cross slide table 7. When the hydraulic oil pump body 3 is started, hydraulic oil is drawn from the hydraulic oil tank 2 and the pressure is transmitted to the hydraulic actuator of the mold clamping arm 9 through the hydraulic pipeline. The mold clamping arm 9 moves to firmly clamp the workpiece on the cross slide table 7, providing stable support for subsequent processing.

[0023] A cross slide 7 is provided on the worktable at the top of the support frame 1. A mold clamping arm 9 is provided on the surface of the support frame 1 for clamping the workpiece to be processed. Both the dual-head power head 8 and the boring power head 10 are equipped with independent heat dissipation components, which include cooling fans and heat dissipation fins. The cooling fans are installed on the outside of the housings of the dual-head power head 8 and the boring power head 10, and the heat dissipation fins are attached to the surface of the motor housings of the dual-head power head 8 and the boring power head 10. Driven by a servo motor, the cross slide 7 slides along a preset trajectory toward the dual-head power head 8. During the sliding process, the lubrication structure delivers lubricating grease to the track to reduce friction. After reaching the processing position, the dual-head power head 8 starts to perform head cutting. At the same time, the cooling fans and heat dissipation fins of the heat dissipation components cool it down. After the head cutting is completed, the cross slide 7 continues to slide to the boring power head 10. The boring power head 10 starts to complete the boring operation. The cooling system nozzles spray water onto the processing area to cool it down. The waste falls into the waste collection box at the bottom of the support frame 1.

[0024] The top worktable of the support frame 1 is equipped with a double-headed power head 8 and a boring power head 10 on both sides. The hydraulic oil tank 2 is equipped with a filter screen. The bottom of the feeding support frame 6 is equipped with a rubber buffer pad to reduce the impact when the workpiece is placed on the support frame. After processing, the boring power head 10 and the double-headed power head 8 stop running. The mold clamping arm 9 is released under the control of the hydraulic system. The loading robot arm 5 moves again to grab the processed workpiece and transfer it to the designated area. The cross slide table 7 is reset to the initial position under the drive of the servo motor, waiting for the next processing cycle to ensure operation safety.

[0025] Working Principle: When using this four-servo automatic head-cutting and boring machine, the workpiece is first placed on the feeding support 6. The loading robotic arm 5, with the help of the position detection component and servo drive, grabs the workpiece and places it on the cross slide 7. Then, the hydraulic oil pump body 3 draws oil from the hydraulic oil tank 2, driving the mold clamping arm 9 to clamp the workpiece. Subsequently, the cross slide 7 is servo-driven to the dual-head power head 8 to complete the head cutting, and then slides to the boring power head 10 for boring. Waste material falls into the collection box. After processing, the mold clamping arm 9 releases, the loading robotic arm 5 removes the workpiece, and the cross slide 7 resets. The entire process is protected by the upper protective cover 4, increasing the overall practicality.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
