Description

Technical Field

[0001] This application belongs to the field of valve core processing, specifically an automatic valve core grinding machine. Background Technology

[0002] As the core component of a valve that enables flow control and sealing, the dimensional accuracy, coaxiality, and surface finish of its outer surface directly determine the valve's sealing performance, response sensitivity, and service life. Especially in high-precision applications, the machining tolerance of the valve core is typically required to be controlled at the micrometer level. This is crucial for subsequent assembly accuracy and overall valve performance. Therefore, grinding and polishing are indispensable key processes in valve core manufacturing.

[0003] Traditional valve core grinding relies heavily on manual operation or semi-automatic equipment. When the valve core moves to the grinding area of ​​the grinding wheel, some of the un-grinded valve core outer walls are difficult to push into the grinding area due to rust and dirt, causing jamming. Workers need to use long poles to push it into the grinding area. At the same time, the metal shavings generated during the grinding process are easy to fly, which not only pollutes the working environment but may also embed into the valve core surface, affecting product quality and even shortening the service life of the equipment. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by designing an automatic valve core grinding machine that automatically pushes the valve core into the grinding area using an automatic extrusion method. This solves the problem that some valve cores, whose outer walls are difficult to push into the grinding area due to rust and dirt, are not being ground.

[0005] To achieve the above objectives, the following technical solution is adopted: An automatic valve core grinding machine includes a frame, a conveyor frame mounted on the upper surface of the frame, baffles fixedly connected to both sides of the conveyor frame, an adjustable grinding frame mounted on the upper surface of the frame, a grinding wheel mounted on the inner wall of the adjustable grinding frame, a support plate fixedly connected to the inner wall of the frame, and a feeding and collecting mechanism provided on the inner wall of the frame, the feeding and collecting mechanism including a pushing component and a collecting component.

[0006] Preferably, the pushing component includes a support frame, which is fixedly connected to the upper surface of the frame. A motor is mounted on the outer wall of the support frame, and a rotating disk is fixedly connected to the output shaft of the motor. A connecting rod is fixedly connected to the inner wall of the rotating disk, and a push rod is rotatably connected to the outer wall of the connecting rod. A magnetic block is fixedly connected to the inner wall of the push rod. A sliding rod is slidably connected to the inner wall of the support frame, and a stop block is fixedly connected to the bottom of the sliding rod. The sliding rod and the support frame are elastically connected by a spring. Preferably, the collection assembly includes a collection cover and a shielding cover. The collection cover is fixedly connected to the upper surface of the frame, the shielding cover is rotatably connected to the inner wall of the adjusting grinding frame, a collection hopper is fixedly connected to the bottom of the collection cover, and a collection box is slidably connected to the inner wall of the frame.

[0007] Preferably, the connecting rod is located at the eccentricity of the rotating disk, and there are two sets of rotating disks, which are symmetrically arranged about the center line of the connecting rod as the axis of symmetry.

[0008] Preferably, the inner wall of the collection hood is rotatably connected to a support roller, and the top shape of the collection hood is set to be arc-shaped.

[0009] Preferably, the magnetic block is fixedly connected to the inner wall of the rotating disk, and the magnetic block is located at the end of the rotating disk away from the connecting rod.

[0010] Preferably, a receiving plate is fixedly connected to the outer wall of the frame, and an inclined push plate is fixedly connected to the end of the receiving plate away from the frame. The inclined push plate is disposed on the upper surface of the conveyor frame. Preferably, the stop block is shaped like an inverted U, the side of the stop block near the rotating disk is inclined, and the push rod is shaped like an arc.

[0011] Compared with the prior art, the beneficial effects of this application are: 1. This application achieves automatic and stable pushing through a pushing component. The motor drives the rotating disk, which in turn drives the push rod through the eccentric connecting rod. The magnetic block ensures the stability of the pushing, and the inclined surface of the stop block causes the push rod to disengage from the magnetic block and adjust the angle. This allows the valve core with rust or dirt to be smoothly pushed into the grinding area, solving the problem of material jamming. No manual intervention is required, improving the reliability of the conveying and the efficiency of process automation.

[0012] 2. This application effectively handles the grinding area covered by the collection hood and shielding hood through the collection component. The arc-shaped top guides the debris to fall and is collected into the collection box through the collection hopper, realizing debris blocking and automatic collection, avoiding environmental pollution and debris embedding into the valve core, reducing equipment wear and extending service life.

[0015] Reference Figures 1-5 An automatic valve core grinding machine includes a frame 1 for mounting and supporting other components. A conveyor frame 2 for transporting valve cores is mounted on the upper surface of the frame 1. Baffles 3 for limiting valve cores are fixedly connected to both sides of the conveyor frame 2. An adjustable grinding frame 4 is mounted on the upper surface of the frame 1. The adjustable grinding frame 4 is used to adjust the grinding position of the grinding wheel 5. The inner wall of the adjustable grinding frame 4 is equipped with the grinding wheel 5 for grinding the valve core. A support plate 11 is fixedly connected to the inner wall of the frame 1. The support plate 11 is used to support the valve core during the grinding process. A feeding and collecting mechanism is provided on the inner wall of the frame 1. The feeding and collecting mechanism includes a pushing component 6 and a collecting component 7. The pushing component 6 is used to push the valve core to be ground to the grinding wheel 5.

[0016] In this embodiment, during use, the valve core is conveyed to the grinding area via the conveyor frame 2. The baffles 3 on both sides limit the valve core to prevent deviation. The pushing component 6 is activated, and the motor 62 drives the rotating disk 63 to rotate. The rotating disk 63 drives the push rod 65 to move via the eccentrically set connecting rod 64. During the rotation of the rotating disk 63, the magnetic block 66 installed inside it attracts the magnetic block 66 inside the push rod 65, keeping the push rod 65 in a stable state, thereby accurately pushing the valve core to the position before grinding on the grinding wheel 5. The diameter of the un-grinded valve core is slightly larger than the space provided by the grinding wheel 5. The rotating disk 63 continues to rotate, and the push rod 65 is disengaged from the magnetic block 66 under the resistance of the stop block 68. The push rod 65 moves to the lower part of the stop block 68 to push the valve core inward for grinding. During the grinding process, the valve core is supported by the support plate 11 to ensure grinding stability.

[0017] During grinding, the position of the grinding wheel 5 is adjusted by adjusting the grinding frame 4 to accommodate the grinding requirements of different valve cores. The grinding wheel 5 grinds the valve core, while the collection cover 71 and shield 72 of the collection assembly 7 cover the grinding area to prevent debris from flying. The debris falls into the collection cover 71 and is then collected into the collection box 74 through the bottom collection hopper 73, achieving automatic collection of debris and avoiding accumulation that affects the grinding effect.

[0018] After grinding, the pushing component 6 continues to work. When the rotating disk 63 rotates to a specific angle, the push rod 65 contacts the inclined surface of the stop block 68. Under the pushing action of the stop block 68, the magnetic block 66 is released from the adsorption. The push rod 65 rotates around the connecting rod 64 and is lifted to avoid obstructing the valve core. The valve core slides out along the receiving plate 8 under the guidance of the inclined push plate 9, completing the automatic material collection. The stop block 68 is elastically reset by the spring 69 to ensure the cyclical operation of the pushing component 6. Throughout the process, the support roller 10 plays an auxiliary stabilizing role for the valve core.

[0019] In a preferred embodiment, the push assembly 6 includes a support frame 61 for mounting and supporting other components. The support frame 61 is fixedly connected to the upper surface of the frame 1 and is supported and fixed by the frame. A motor 62 for driving the rotating disk 63 to rotate is mounted on the outer wall of the support frame 61. The output shaft of the motor 62 is fixedly connected to the rotating disk 63 for driving the push rod 65 to move. A connecting rod 64 is fixedly connected to the inner wall of the rotating disk 63. The connecting rod 64 is used to mount the push rod 65. The push rod 65 is rotatably connected to the outer wall of the connecting rod 64. The push rod 65 is used to push the valve core into the grinding position of the grinding wheel 5. A magnetic block 66 is fixedly connected to the inner wall of the push rod 65. The magnetic block 66 installed inside the rotating disk 63 will attract the push rod. The magnetic block 66 inside the support frame 61 is slidably connected to a sliding rod 67 for moving the stop 68. The bottom of the sliding rod 67 is fixedly connected to the stop 68. The magnetic block 66 inside the rotating disk 63 attracts the push rod 65 to keep it stable, causing the end of the push rod 65 away from the connecting rod 64 to be lifted, so that the valve core is not blocked by the push rod 65. After the valve core is processed below the push rod 65, the rotating disk 63 continues to rotate. When rotating, the inclined surface of the stop 68 abuts against the push rod 65, causing the magnetic block 66 to detach from the attraction, and then the next push can be performed. The sliding rod 67 and the support frame 61 are elastically connected by a spring 69. The spring 69 moves the stop 68 up and then resets it to avoid blocking it when the push rod 65 retracts.

[0020] As a preferred method, the collection component 7 is used to collect the debris generated during grinding to prevent debris accumulation from affecting grinding. The collection component 7 includes a collection cover 71 and a shield 72. The collection cover 71 is fixedly connected to the upper surface of the frame 1 and is supported and fixed by the frame 1. The shield 72 is rotatably connected to the inner wall of the adjustable grinding frame 4 and can cover the upper part of the grinding area by rotation to prevent debris from splashing. The bottom of the collection cover 71 is fixedly connected to a collection hopper 73, which is used to collect the fallen debris into the collection box 74. The collection box 74 is slidably connected to the inner wall of the frame 1.

[0021] As a preferred method, the connecting rod 64 is set at the eccentric position of the rotating disk 63. When rotating, it can cause the push rod 65 connected to the outer wall to extend and retract. There are two sets of rotating disks 63, which are symmetrically arranged about the center line of the connecting rod 64 to maintain the stability of the connecting rod 64 and allow the push rod 65 to rotate along the connecting rod 64.

[0022] As a preferred embodiment, the inner wall of the collection cover 71 is rotatably connected to a support roller 10 for stabilizing the grinding valve core, and the top shape of the collection cover 71 is set to be arc-shaped to prevent grinding debris from splashing and to allow the debris falling inside to fall into the collection hopper 73.

[0023] As a preferred embodiment, the magnetic block 66 is fixedly connected to the inner wall of the rotating disk 63, and the magnetic block 66 is located at the end of the rotating disk 63 away from the connecting rod 64, so that the push rod 65 that is attracted and fixed is longer.

[0024] As a preferred embodiment, a receiving plate 8 for collecting the ground material is fixedly connected to the outer wall of the frame 1. An inclined push plate 9 is fixedly connected to the receiving plate 8 away from the frame 1 to block the valve core on the conveyor frame 2 and guide it toward the receiving plate 8. The inclined push plate 9 is located on the upper surface of the conveyor frame 2.

[0025] As a preferred method, the stop 68 is shaped like an inverted U to allow the valve core to pass smoothly underneath. The side of the stop 68 closest to the rotating disk 63 is tilted to move the push rod 65 away from the magnetic block 66. The push rod 65 is shaped like an arc, and its upper surface will contact the stop 68 during retraction. The arc shape makes the contact friction process more stable.
