Detailed Implementation

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0012] like Figure 1-15 As shown, this embodiment includes a base 1, a bridge plate 2, a sub-plate 3, an overall rotating mechanism, a lifting mechanism, a sub-plate rotating mechanism, and a zero-point positioning system.

[0013] The overall rotating mechanism includes a turntable 40 and a tailstock 41 fixed at both ends of the base 1, an L-plate I 16 fixed on the turntable rotating disk, and an L-plate II 17 fixed on the tailstock rotating disk. One end of the bridge plate 2 is fixed to the L-plate I 16, and the other end is fixed to the L-plate II 17. An oil distributor I 39 fixed on the turntable 40 passes through the large central hole of the turntable 40 and is fixed to the oil / gas inlet I of the L-plate I 16. An oil / gas outlet I is provided at the other end of the L-plate I 16. An oil distributor III 47 fixed on the tailstock 41 passes through the large central hole of the tailstock 41 and is fixed to the oil / gas inlet III of the L-plate II 17. An oil / gas outlet III is provided at the other end of the L-plate II 17.

[0014] The lifting mechanism includes a support 46 fixed to the bottom surface of the bridge plate 2, a cylinder support 30 hinged to the bottom of the support 46 by a first pin 51, two (or three, four, etc.) linear cylinders 45 evenly distributed and fixed to the bottom of the cylinder support 30, an oil circuit distributor II 43, and an oil circuit plate 28. Each linear cylinder 45 has a joint 23 mounted on the end of its piston rod. The joint 23 is hinged and fixed to the lower ends of both ends of the lifting plate 26 by a second pin 55. The lifting plate 26 is fixed to the lower end face of the lifting shaft 25. The bridge plate 2 and the sub-plate 3 have interconnected lifting shaft mounting holes and stepped holes at their center points. The lifting shaft 25 is slidably mounted in the lifting shaft mounting hole of the bridge plate 2, and its upper end is rotatably fixed in the stepped hole of the sub-plate 3. In this embodiment, the lifting shaft 25 is installed in the lifting shaft mounting hole via a first bearing 42. A first bearing end cap 24, fixed to the lower end face of the bridge plate 2, and a second bearing end cap 29, fixed to the upper end face of the bridge plate 2, are installed at both ends of the first bearing 42. A first dustproof ring 49 is press-fitted between the first bearing end cap 24 and the lifting shaft 25. The upper end of the lifting shaft 25 is installed in the stepped hole of the sub-plate 3 by a second bearing 44, and two (or three, etc.) locating pins are evenly fixed at its upper end, placed in the annular grooves of the oil passage plate 28 and the sub-plate 3.

[0015] A through hole is formed in the center of the lifting shaft 25. The hydraulic distributor II 43 passes through the center hole of the lifting plate 26 and the through hole of the lifting shaft 25 and is fixed to the lower end of the hydraulic circuit plate 28. Its oil / gas outlet III is connected to the oil / gas inlet IV of the hydraulic circuit plate 28. Hydraulic distributors I 39 and III 47 supply hydraulic oil to two linear cylinders 45. Each linear cylinder 45 has an oil pressure detection function. Under the action of hydraulic oil, the piston rods of the linear cylinders 45 move, driving the lifting shaft 25 up and down through a hinge mechanism, thereby driving the sub-plate 3 to move up and down. This mechanism provides smooth lifting and lowering. Simultaneously, the linear cylinders 45 have push-out and retraction signal detection functions to detect the status of this lifting mechanism, ensuring that the lifting and lowering are complete, thus meeting the needs of tooling automation.

[0016] The sub-plate rotation mechanism includes a forward and reverse hydraulic motor 36, a gear 19, a sector rack 13, an angle baffle I 10, an angle baffle II 11, an air detection support 9, two sets of air detection components 35, and a pin mechanism 7. The bridge plate 2 and the sub-plate 3 have corresponding through mounting holes. The hydraulic motor 36 is fixed to the bottom surface of the bridge plate 2, and its output shaft and connecting shaft 15 are fixed together by screws 53 fixed to the upper end face of the connecting shaft 15. The output shaft and connecting shaft 15 are embedded in the mounting holes of the bridge plate 2 and the sub-plate 3. The upper end of the connecting shaft 15 is fitted with and fixed to the gear 19 by a retaining ring 52 snapped onto the upper end of the connecting shaft 15. In this embodiment, the output shaft and the connecting shaft 15 are fixed together by a snap-fit ​​connecting sleeve 14; the connecting sleeve 14 has a clearance fit with the through mounting holes of the bridge plate 2 and the sub-plate 3. A sector rack 13, meshing with gear 19, is fixed to the bottom surface of adapter plate 21, which is fixed to the upper surface of sub-plate 3. The central axis of sector rack 13 coincides with the central axis of lifting shaft 25. Angle baffles I 10 (clockwise rotation) and II 11 (counterclockwise rotation) are respectively installed on both sides of the upper surface of bridge plate 2. Relative to the initial position, the angles at which sub-plate 3 rotates clockwise and counterclockwise are the same. An air detection support 9 is fixed to the bottom surface of sub-plate 3, with air detection components 35 installed at both ends. When sub-plate 3 rotates clockwise until angle baffle I 10 contacts one of the air detection components 35, sub-plate 3 is in position, and hydraulic motor 36 stops working; or when sub-plate 3 rotates counterclockwise until angle baffle II 11 contacts the other air detection component 35, sub-plate 3 is in position, and hydraulic motor 36 stops working. A pin mechanism 7 is also installed on the bottom surface of the bridge plate 2. The pin mechanism 7 includes a cylinder 7-1 fixed to the bottom surface of the bridge plate 2 and a stop pin 7-3 fixed to the piston rod of the cylinder 7-1 by an adapter 7-2. The cylinder body of the cylinder 7-1 is provided with a stop pin extension air detection interface 7-7 and a stop pin retraction air detection interface 7-6. The stop pin 7-3 is slidably connected in the sliding hole of the bridge plate 2. A guide plate 8 is fixed to the end of the sliding hole. A third dustproof ring 7-5 is provided at the cylinder body opening of the stop pin 7-3 and the cylinder body opening of the cylinder 7-1. When the air detection assembly 35 contacts the extended stop pin 7-3, the sub-plate 3 rotates to the initial position, and the hydraulic motor 36 stops rotating. The air detection support 9 is provided with an air passage communicating with the air passage of the air detection assembly 35.

[0017] The zero-point positioning system includes three or more zero-point positioning units 37 evenly arranged on the top surface of the bridge plate 2, twice the number of rivet seats 4 fixed on the sub-plate 3, and rivets 38 installed on the rivet seats 4. The central angle between the central axis of the rivets 38 located at both ends of the zero-point positioning unit 37 and the central axis of the zero-point positioning unit 37 is the same and is the angle at which the sub-plate 2 rotates clockwise or counterclockwise into position.

[0018] Oil distributor I 39, oil distributor III 47, and oil circuit board 28 provide air and hydraulic oil to each linear cylinder 45, hydraulic motor 36, pin mechanism 7, and zero-point positioning unit 37. Each linear cylinder 45 and hydraulic motor 36 has an oil pressure detection function; the pin mechanism 7 and each zero-point positioning unit 37 have an air pressure detection function.

[0019] This embodiment also includes a protective system. The protective system includes a connecting plate II 34 fixed to the circumferential wall of the bridge plate 2, a connecting plate I 33 fixed to the circumferential wall of the sub-plate 3, a telescopic protective cover 32 fixed to the lower end of the connecting plate I 33, a sheet metal cover plate 20 fixed to the lower end of the protective cover 32, and an inverted L-shaped sheet metal pressure plate 18 fixed to the connecting plate II 34. The sheet metal cover plate 20 is snapped onto the L-shaped sheet metal pressure plate 18. In this embodiment, the telescopic protective cover 32 is a corrugated protective cover. This structure ensures that the protective cover 32 can rotate with the sub-plate 3, and the telescopic function of the protective cover 3 meets the requirements for lifting and lowering the sub-plate 3; the entire protective system can protect the zero-point positioning system, the center rotation mechanism, the lifting mechanism, and the sub-plate rotation mechanism, preventing impurities such as iron filings and cutting fluid from affecting these mechanisms during machining.

[0020] The operation process of this invention is as follows: For different products being processed, corresponding fixtures are installed on the top surface of the sub-plate 3 to ensure product positioning and clamping. The necessary oil and air passages on the fixtures are provided through oil and air ports on the oil passage plate 28. When the processing features of the product require two angles, the required rotation angles of the turntable 40 and sub-plate 3 are determined through calculation. The product is loaded and unloaded when the sub-plate 3 is in a horizontal state, i.e., its initial state. During operation, the product to be processed is first installed on the upper surface of the sub-plate 3. Then, the zero-point positioning units are connected to compressed air for unlocking. The sub-plate 3 is raised using the lifting mechanism. When it reaches its highest position, the linear hydraulic cylinder 45 sends a positioning signal, and simultaneously, the zero-point positioning system's positioning surface air detector also provides a feedback signal. The next operation is executed upon confirmation of these dual signals. According to the required rotation angle, the hydraulic motor 36 is connected to hydraulic oil, driving the subplate 3 to rotate through the subplate rotation mechanism. When the air detection component 35 contacts the angle baffle I 10 or the angle baffle II 11, the air detection component 35 sends a feedback signal, and the hydraulic motor 36 stops rotating. Each zero-point positioning unit is connected to compressed air to unlock, and the subplate 3 is lowered through the lifting mechanism. When it reaches the lowest position, the pull stud 38 quickly engages with the zero-point positioning unit 37, and the linear cylinder 45 sends a positioning signal. Simultaneously, the air detection of the zero-point positioning system's positioning surface also sends a feedback signal. After confirmation by these dual signals, the zero-point positioning unit cuts off the compressed air, thus ensuring that the subplate 3 is quickly positioned and locked. Then, the turntable 40 is controlled to rotate to the required angle, thereby driving the entire fixture to rotate to the designated position for machining. After machining, the turntable 40 is controlled to rotate to the initial position, and each zero-point positioning unit is connected to compressed air to unlock. The subplate 3 is raised through the lifting mechanism. When it reaches the highest position, the linear cylinder 45 sends a positioning signal, and simultaneously, the air detection of the zero-point positioning system's positioning surface also sends a feedback signal. Under the action of cylinder 7-1, stop pin 7-3 extends forward. When stop pin 7-3 extends, the air detection port 7-7 of the extended stop pin is connected to compressed air and a feedback signal is sent to ensure that stop pin 7-3 extends into place. Hydraulic motor 36 is connected to hydraulic oil, which drives subplate 3 to rotate through subplate rotation mechanism. When air detection component 35 contacts stop pin 7-3, air detection component 35 sends a signal, and hydraulic motor 36 stops rotating, thus ensuring that subplate 2 rotates to the initial position. Stop pin 7-3 retracts under the action of cylinder 7-1, and air detection interface 7-6 connects to compressed air and sends a signal to ensure that stop pin 7-3 retracts into place. Zero-point positioning units at various locations are unlocked by compressed air, and subplate 3 is lowered through lifting mechanism. When it descends to the lowest position, pull pin 38 quickly engages with zero-point positioning unit 37, linear cylinder 45 sends a positioning signal, and at the same time, air detection on positioning surface of zero-point positioning system also sends a signal. After confirmation by dual signals, zero-point positioning unit cuts off compressed air, thus ensuring that subplate 3 is quickly positioned and locked. Then the processed product is taken off, and the above steps are repeated in sequence to realize automated product processing.

[0021] This invention enables the machining of parts with inclined surfaces and inclined holes that must be processed by five-axis equipment to be realized in a common three-axis vertical machining center. It has a simple structure, low price, fast response speed, strong adaptability, good stability and high degree of automation.

[0022] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
