Description

Technical Field

[0001] The present invention relates to the technical field of feeding equipment, and particularly relates to a feeding device for crankcase machining. Background Art

[0002] The crankcase is a key component in a compressor. It bears moving components such as the crankshaft and connecting rod, and connects them to other parts of the compressor (such as cylinders, pistons, etc.). The main function of the crankcase is to support the crankshaft and connecting rod, enable them to operate in the correct position, and ensure the accuracy of their relative positions and motion trajectories.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1 - 7 As shown, the present invention is a feeding device for crankcase processing, including an installation cylinder 1. A bearing plate 14 is fixedly connected to the top surface of the installation cylinder 1. A positioning seat 20 is fixedly connected to the inner side edge of the installation cylinder 1. An air guide head 31 is fixedly connected to the side surface of the installation cylinder 1;

[0028] A connecting cylinder 33 is fixedly connected to the bottom surface of the air guide head 31. A splitting frame 36 is welded and fixed to the inner surface of the connecting cylinder 33. A connecting shell 37 is fixedly connected to the top surface of the splitting frame 36. A sleeve 38 is fixedly connected to the top surface of the connecting shell 37. A clamping groove is provided inside the sleeve 38. A clamping head 45 is embedded and connected to the surface of the clamping groove. A clamping rod 46 is fixedly connected to the surface of the clamping head 45. A diversion frame 47 is fixedly connected to the surface of the clamping rod 46. A guiding block is fixedly connected to the side surface of the diversion frame 47;

[0029] A vibration bin 2 is fixedly installed on the bottom surface of the installation cylinder 1. A vibration motor is fixedly installed inside the vibration bin 2. Air valves 3 are symmetrically and fixedly connected to the side surface of the installation cylinder 1. The output end of one of the air valves 3 is fixedly connected to a nozzle 4. A limiting sleeve 5 is fixedly connected to the inner surface of the installation cylinder 1 above the nozzle 4. A guiding hose 6 is fixedly connected to the inner surface of the installation cylinder 1 at the position of the nozzle 4. After starting the vibration motor, the installed crankcase will be affected by vibration at a certain frequency and amplitude, so that the metal chips and oil stains generated during the processing will fall off, thereby keeping the bearing plate 14 clean;

[0030] One end of the guiding hose 6 is fixedly connected to a telescopic tube 7 at the edge of the side surface. One surface of one end of the guiding hose 6 is fixedly connected to a collar 8. The side surface of the collar 8 is fixedly connected to a guiding tube 9. The surface of the collar 8 is fixedly connected to a butt joint tube 10. One end of the side surface of the butt joint tube 10 is fixedly connected to an annular plate 11 at the edge. One surface of one end of the butt joint tube 10 is fixedly connected to a curved surface screen 12. The inner surface of the mounting cylinder 1 is fixedly connected to a fixed tube 13. The butt joint tube 10 is fixedly connected to the fixed tube 13. When the crankcase is placed and processed for feeding, the user can connect high-pressure air from the air valve 3 at the nozzle 4, then pass through the nozzle 4, and finally blow out from the air valve 3 at the other end. The telescopic tube 7 above the guiding hose 6 will generate a certain negative pressure, thereby adsorbing the crankcase to keep it stable during the whole process, improving the processing efficiency and reducing the defective rate. At the same time, the separated metal chips and oil stains will enter the guiding hose 6 under the influence of the negative pressure, and then be blown towards the butt joint tube 10 by the high-pressure air. Affected by the curved surface screen 12, the metal chips will be blown towards the collar 8 due to the curvature of its surface, and after the subsequent operation is completed, they will fall into the guiding tube 9 under the influence of gravity to wait for subsequent centralized collection and recycling. The separated oil stains will flow towards the air guiding head 31 along with the high-pressure air to wait for subsequent separation treatment;

[0031] A butt joint hole 15 is provided in the middle of the surface of the bearing plate 14. The side surface of the bearing plate 14 is fixedly connected to an elastic sleeve 16. The elastic sleeve 16 is fixedly connected to the mounting cylinder 1. The bottom surface of the elastic sleeve 16 is fixedly connected to a socket 17. The surface of the socket 17 is rotatably connected to a connecting rod 18. One surface of one end of the connecting rod 18 is fixedly connected to a pressing block 19. When placing the crankcase, the shaft rod on the surface of the crankcase can be inserted into the butt joint hole 15, and then the whole is placed flat on the surface of the bearing plate 14. Under the influence of gravity, the whole elastic sleeve 16 will deform, and then the telescopic tube 7 shrinks, causing the bearing plate 14 to move downward. At this time, the connecting rod 18, the socket 17 and the limiting sleeve 5 will also move vertically downward, and finally the pressing block 19 will press against the surface of the guiding hose 6, thereby further improving the negative pressure effect;

[0032] At the four corner edges of the top surface of the positioning seat 20, screw rods 21 are fixedly connected. The surface of the screw rods 21 is fixedly connected to a bottom plate 22. The top surface of the bottom plate 22 is fixedly connected to a bottom frame 23. A top frame 24 is arranged at the upper end of the bottom frame 23. The top surface of the top frame 24 is fixedly connected to a guiding rail 29. The top surface of the guiding rail 29 is fixedly connected to a cover 30;

[0033] The bottom surface of the top frame 24 is fixedly connected with an armature 25. The two short side surfaces of the top frame 24 are fixedly connected with inclined plates 27. The two long side surfaces of the top frame 24 are fixedly connected with baffles 28. The surface of the two baffles 28 is fixedly connected with an electromagnet 26. After the metal chips enter the guide rail 29 through the guide pipe 9, the user can control the electromagnet 26 to be periodically energized to generate magnetism. Under the influence of the armature 25 and in cooperation with the setting of the inclined plate 27, continuous vibration will be generated at the upper end of the entire bottom plate 22, so that the metal chips are orderly guided to one end of the guide rail 29 and finally fall off, and the user can thus collect them uniformly;

[0034] A sealing piece 32 is fixedly connected inside the air guide head 31. A filter element 39 is embedded and connected inside the connecting shell 37. The bottom surface of the splitting frame 36 is fixedly connected with a guide shell 40. An air inlet groove is provided on the side surface of the guide shell 40. The bottom surface of the guide shell 40 is fixedly connected with a sleeve frame 41. The top surface of the inner part of the sleeve frame 41 is fixedly connected with a spring 42. The bottom surface of the spring 42 is fixedly connected with a piston 43. The bottom surface of the piston 43 is fixedly connected with a blocking rod 44. The bottom surface of the connecting cylinder 33 is fixedly connected with a guide head 34. A docking head 35 is embedded and connected inside the guide head 34. The blocking rod 44 is embedded and connected with the docking head 35. After the high-pressure air mixed with oil enters the air guide head 31, it will first be affected by the sealing piece 32 and then blown towards the diversion frame 47. Under the action of the guide block, the entire diversion frame 47 will drive the embedding rod 46 to rotate self-rotationally. Affected by the centrifugal force, the oil stain will be thrown out and slide down along the inner wall of the connecting cylinder 33 and finally converge inside the docking head 35. The high-pressure air will enter the connecting shell 37 through the air inlet groove on the surface of the guide shell 40, and cooperate with the filter element 39 for final filtration, and then move upward all the way and finally blow out from the other end outlet of the air guide head 31, thus completely completing the step of separating the oil stain. In order to reduce the manual cleaning workload, after the oil stain reaches a certain degree, the piston 43 and the blocking rod 44 will gradually separate from the docking head 35 under the influence of buoyancy. After the gap leaks, the excess oil stain will flow out. A collection device can be set up in advance for collection. After that, the spring 42 resets to avoid impurities and the like from entering the inside of the connecting cylinder 33 from the lower end of the docking head 35.

[0035] Working principle of the present invention: After starting the vibration motor, the installed crankcase will be affected by vibrations of a certain frequency and amplitude, causing the metal chips and oil stains generated during the processing to fall off, thereby keeping the bearing plate 14 clean. When loading materials for processing after the crankcase is placed, the user can connect high-pressure air from the air valve 3 at the nozzle 4, then pass through the nozzle 4, and finally blow out from the air valve 3 at the other end. The telescopic tube 7 above the guiding hose 6 will generate a certain negative pressure, thereby adsorbing the crankcase and enabling it to remain stable throughout the process, improving the processing efficiency and reducing the defective rate. At the same time, the metal chips and oil stains that fall off will enter the guiding hose 6 under the influence of the negative pressure, and then be blown towards the docking pipe 10 by the high-pressure air. Affected by the arc-shaped screen 12, the metal chips will be blown towards the ring sleeve 8 on the surface of its arc, and after the subsequent operation is completed, they will fall into the guiding pipe 9 under the influence of gravity to wait for subsequent centralized collection and recycling. The separated oil stains will flow towards the air guide head 31 along with the high-pressure air to wait for subsequent separation treatment. When placing the crankcase, the shaft rod on the surface of the crankcase can be inserted into the docking hole 15, and then the whole is placed flat on the surface of the bearing plate 14. Under the influence of gravity, the entire elastic sleeve 16 will deform, and then the telescopic tube 7 will contract, causing the bearing plate 14 to move downward. At this time, the connecting rod 18, the socket 17, and the limit sleeve 5 will also move vertically downward, and finally the pressing block 19 will press against the surface of the guiding hose 6, further enhancing the negative pressure effect. After the metal chips enter the guiding rail 29 through the guiding pipe 9, the user can control the electromagnet 26 to be periodically energized to generate magnetism. Under the influence of the armature 25 and in cooperation with the setting of the inclined plate 27, the upper end of the entire bottom plate 22 will continuously vibrate, causing the metal chips to be orderly guided to one end of the guiding rail 29 and finally fall off, so that the user can collect them uniformly. The high-pressure air mixed with oil stains will be affected by the sealing piece 32 after entering the air guide head 31, and then blown towards the diversion frame 47. Under the action of the guiding block, the entire diversion frame 47 will drive the embedded rod 46 to rotate self-rotationally. Affected by the centrifugal force, the oil stains will be thrown out and slide down along the inner wall of the connecting cylinder 33, and finally converge inside the docking head 35. The high-pressure air will enter the connecting shell 37 through the air inlet groove on the surface of the guiding shell 40, and cooperate with the filter element 39 for final filtration, and then move upward all the way, and finally blow out from the other end outlet of the air guide head 31, thus completely completing the oil stain separation step. In order to reduce the manual cleaning workload, after the oil stains reach a certain level, the piston 43 and the blocking rod 44 will gradually separate from the docking head 35 under the influence of buoyancy. After the gap leaks, the excess oil stains will flow out, and a collection device can be set up in advance for collection. Then the spring 42 will reset, preventing impurities and the like from entering the inside of the connecting cylinder 33 from the lower end of the docking head 35.
