Description

Technical Field

[0001] This invention relates to the field of grinding disc vibration mechanism technology, and more particularly to a vibration device for abrasive grinding tools. Background Technology

[0002] Abrasives and grinding tools are a general term for abrasives and grinding tools. In the production and preparation of grinding wheels, the feeding of abrasive grains for grinding wheels is usually done using a vibratory feeder. When abrasive grains are used repeatedly at high intensity and frequency during grinding, they are prone to clumping. They need to be broken up by vibration and then re-fed. However, the existing abrasive vibration device can only discharge the abrasive uniformly after the device is used up, break it up by vibration, and then feed it back in through a vibratory feeder. The vibration effect is not good, the clumping and breaking time is long, and there are certain limitations in its use.

[0003] Therefore, we have made improvements to this by proposing a vibration device for abrasive grinding wheels. Summary of the Invention

[0004] To achieve the above-mentioned objectives, the present invention provides a vibration device for abrasive grinding tools, comprising a support structure, the support structure comprising a fixedly connected base and a column, the upper and lower ends of the column being respectively connected to a first connecting sleeve and a second connecting sleeve, and the upper end of the base being connected to a locking block, an upper swing mechanism being sleeved inside the first connecting sleeve, a lower swing mechanism being sleeved inside the second connecting sleeve, a plurality of swing rods being connected in the middle of the upper and lower swing mechanisms, a grinding mechanism being connected in the middle of the swing rods, a feed pipe being connected in the middle of the upper swing mechanism and the grinding mechanism, and a discharge pipe being connected in the middle of the lower swing mechanism and the grinding mechanism.

[0005] The upper swing mechanism includes an eccentrically sleeved first fixed frame and a first swing frame. Several first electric push rods are connected in the middle of the first fixed frame and the first swing frame, and several first connecting lugs are installed at the bottom of the first swing frame.

[0006] The lower swing mechanism includes a second fixed frame and a second swing frame that are eccentrically connected. Several second electric push rods are connected to the middle of the second fixed frame and the second swing frame. The bottom of the second swing frame has a circular groove and an elliptical hammer plate is sleeved on it. An eccentric shaft is eccentrically connected to the bottom of the elliptical hammer plate. A servo motor is provided at the bottom of the eccentric shaft. Both the eccentric shaft and the output shaft of the servo motor are provided with pulleys. The eccentric shaft and the servo motor are connected to the same transmission belt through the pulleys. Several second connecting lugs are installed at the upper end of the second swing frame.

[0007] The grinding mechanism includes a connecting cylinder, an upper grinding disc connected to the upper flange of the connecting cylinder, a lower grinding disc connected to the lower flange of the connecting cylinder, and a connection port opened in the middle of the connecting cylinder.

[0008] The feed pipe includes a tapered folded telescopic tube, the bottom of which is connected to a flexible hose. Both the upper end of the telescopic tube and the bottom of the flexible hose are connected to metal connecting plates. The upper and lower ends of the feed pipe are welded and installed to the upper swing mechanism and the grinding mechanism through the metal connecting plates.

[0009] The swing rod has a ball joint in the middle and is connected to the outside of the connecting cylinder through the ball joint.

[0010] The feed pipe and the discharge pipe have the same structure and function, and both the feed pipe and the discharge pipe are fitted with screen filter plates inside.

[0011] The first swing frame has a funnel-shaped through groove in the middle, and the bottom opening diameter of the through groove is the same as the upper port diameter of the telescopic tube.

[0012] The upper surface of the base is inclined at 15 degrees, and the bottom of the base has a cavity, with the servo motor and eccentric shaft both sleeved in the bottom cavity of the base.

[0013] The supporting structure, grinding mechanism, and eccentric shaft are located on the same axis and remain stable.

[0014] The number of the first connecting ear, the swing rod, and the second connecting ear are all six, and the six swing rods are connected one by one to the middle of the first connecting ear and the second connecting ear on the same side.

[0015] The first and second electric actuators are equipped with couplings at both ends. There are eight of each type of actuator, and all eight first and eight second electric actuators are connected with equal rounded corners.

[0016] The vibration device for abrasive grinding wheels provided by this invention has the following advantages:

[0017] 1. By setting up a grinding mechanism to enclose the grinding disc, the abrasive material produced during grinding is prevented from splashing out and causing waste. The grinding mechanism is fixed in the center of the support structure by the drive shaft on the grinding disc and connected to the middle of the swing rod. The upper and lower swing mechanisms are respectively connected to the upper and lower swing mechanisms. The upper and lower swing mechanisms are respectively connected to the grinding mechanism by the feed pipe and the discharge pipe. The lower swing mechanism drives the upper swing mechanism to rotate eccentrically, causing the swing rod, feed pipe and discharge pipe to swing and twist. The feed pipe and discharge pipe are used for feeding and discharging the grinding disc inside the grinding mechanism.

[0018] 2. By connecting the bottom end of the discharge pipe to the middle of the grinding mechanism and the lower swing mechanism, an elliptical hammer plate is sleeved on the bottom of the second swing frame. The elliptical hammer plate is driven to swing eccentrically by the rotation of the eccentric shaft, which rotates and impacts the second swing frame. This causes the second swing frame to compress the second electric push rod and impact the second fixed frame, generating swing and vibration. The vibration and shaking of the second swing frame drive the discharge pipe to shake and vibrate, so that the ground abrasive inside the discharge pipe can be discharged quickly. A screen can be installed at the bottom end of the discharge pipe to screen out the abrasive by shaking and vibrating the discharge pipe.

[0019] 3. Connect the second connecting ear at the upper end of the second swing frame to the second swing frame via a swing rod. The middle part of the swing rod is fixed through the center of the grinding mechanism, so that the vibration and swing on the second swing frame can be transmitted by the swing rod, so that the first swing frame can vibrate and swing accordingly. The vibration and swaying frequency generated by the shaking of the first swing frame is used to convey the abrasive inside the feed pipe connected to the upper swing mechanism downward, so as to avoid the accumulation of abrasive and ensure the production and processing of the grinding wheel.

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] like Figures 1-7 As shown, this embodiment proposes a vibration device for abrasive grinding tools, including a support structure 1. The support structure 1 includes a base 14 and a column 11 fixedly connected. The upper and lower ends of the column 11 are respectively connected to a first connecting sleeve 12 and a second connecting sleeve 13, and the upper end of the base 14 is connected to a locking block 15. An upper swing mechanism 2 is sleeved inside the first connecting sleeve 12, and a lower swing mechanism 4 is sleeved inside the second connecting sleeve 13. A plurality of swing rods 3 are connected in the middle of the upper swing mechanism 2 and the lower swing mechanism 4. A grinding mechanism 5 is connected in the middle of the swing rods 3. A feed pipe 6 is connected in the middle of the upper swing mechanism 2 and the grinding mechanism 5, and a discharge pipe 7 is connected in the middle of the lower swing mechanism 4 and the grinding mechanism 5. The upper swing mechanism 2 includes a first fixed frame 21 and a first swing frame 22 eccentrically sleeved. A number of first electric push rods 23 are connected to the middle of the fixed frame 21 and the first swing frame 22. A number of first connecting ears 24 are installed at the bottom of the first swing frame 22. The lower swing mechanism 4 includes a second fixed frame 41 and a second swing frame 42 that are eccentrically connected. A number of second electric push rods 43 are connected to the middle of the second fixed frame 41 and the second swing frame 42. A circular groove is opened at the bottom of the second swing frame 42 and an elliptical hammer plate 44 is sleeved on it. An eccentric shaft 45 is eccentrically connected to the bottom of the elliptical hammer plate 44. A servo motor 47 is provided at the bottom of the eccentric shaft 45. Both the output shaft of the eccentric shaft 45 and the servo motor 47 are provided with pulleys. The eccentric shaft 45 and the servo motor 47 are connected to the same transmission belt 46 through the pulleys. A number of second connecting ears 48 are installed at the upper end of the second swing frame 42.

[0031] The grinding mechanism 5 includes a connecting cylinder 51. An upper grinding disc 52 is connected to the upper flange of the connecting cylinder 51, and a lower grinding disc 53 is connected to the lower flange of the connecting cylinder 51. A connection port 54 is provided in the middle of the connecting cylinder 51, which allows for the separate connection of the connecting cylinder 51, the upper grinding disc 52, and the lower grinding disc 53. This facilitates the separate installation and disassembly of the grinding discs inside the upper grinding disc 52 and the lower grinding disc 53, and makes it easy to replace and maintain the grinding discs. This ensures the grinding effect of the upper grinding disc 52 and the lower grinding disc 53 on the agglomerated abrasive. The connection port 54 and the drive shaft are used to traction and position the grinding mechanism 5, which facilitates the overall stability of the device. The connection port 54 also facilitates the timely addition and replenishment of abrasive sand, ensuring the processing effect of the grinding wheel.

[0032] The feed pipe 6 includes a tapered folded telescopic pipe 61. A flexible hose 62 is connected to the bottom of the telescopic pipe 61. Metal connecting plates are connected to the upper end of the telescopic pipe 61 and the bottom of the flexible hose 62. The upper and lower ends of the feed pipe 6 are welded to the upper swing mechanism 2 and the grinding mechanism 5 through the metal connecting plates. The connection between the telescopic pipe 61 and the flexible hose 62 connects the swinging upper swing mechanism 2 with the feed port of the upper grinding plate 52, which facilitates the introduction of abrasive by the swinging of the upper swing mechanism 2 during the feeding process and avoids clogging when the abrasive is fed.

[0033] The middle part of the swing rod 3 is connected to a ball joint, and it is connected to the outside of the connecting cylinder 51 through the ball joint. Through the connection between the grinding mechanism 5 and the swing rod 3, the swing rod 3 is fixed in the middle and swings at both ends after installation, which facilitates the connection and transmission of the upper swing mechanism 2 and the lower swing mechanism 4.

[0034] The feed pipe 6 and the discharge pipe 7 have the same structure and function. The discharge pipe 7 is also fitted with a screen filter. The feed pipe 6 and the discharge pipe 7 serve as the feed end and discharge end of the grinding mechanism 5, respectively, to feed and discharge materials. The vibration of the device is used to clear and screen the abrasive, which facilitates the crushing and grinding of the abrasive.

[0035] The first swing frame 22 has a funnel-shaped through groove in the middle, and the bottom opening diameter of the through groove is the same as the upper port diameter of the telescopic tube 61. The funnel of the first swing frame 22 is connected to the feed pipe 6, so that the abrasive is automatically conveyed into the feed pipe 6 after being poured into the middle of the first swing frame 22, preventing blockage when the abrasive is fed.

[0036] The upper surface of the base 14 is inclined at 15 degrees, and the bottom of the base 14 is provided with a cavity. The servo motor 47 and the eccentric shaft 45 are both sleeved in the bottom cavity of the base 14. The upper surface of the base 14 slides the abrasive discharged from the discharge pipe 7 downward, so that the abrasive accumulates on one side, which is convenient for collecting the abrasive. The eccentric shaft 45 and the servo motor 47 are sleeved on the base 14 to facilitate the fixation of the axis of the base 14, making the use of the device more stable.

[0037] The support structure 1, the grinding mechanism 5, and the eccentric shaft 45 are on the same axis and remain stable. When the axis of the support structure 1, the grinding mechanism 5, and the eccentric shaft 45 is stationary, the upper swing mechanism 2 and the lower swing mechanism 4, together with the feed pipe 6 and the discharge pipe 7, twist at the upper and lower ends of the grinding mechanism 5 respectively. The swinging and vibration generated by the twisting facilitates the processing of the abrasive and does not interfere with the operation of the grinding disc inside the grinding mechanism 5, thereby improving the working efficiency of the device.

[0038] There are six first connecting ears 24, six swing rods 3, and six second connecting ears 48. The six swing rods 3 are connected one by one to the middle of the first connecting ears 24 and the second connecting ears 48 on the same side. The swing rods 3 connect the upper swing mechanism 2 and the lower swing mechanism 4, so that the upper swing mechanism 2 and the lower swing mechanism 4 swing and shake in linkage, which facilitates the use of the device.

[0039] Both ends of the first electric push rod 23 and the second electric push rod 43 are equipped with couplings. There are eight of each type of electric push rod. The eight first electric push rods 23 and the eight second electric push rods 43 are connected with equal rounded corners. The connection of the first electric push rods 23 and the second electric push rods 43 facilitates smooth shaking between the first fixed frame 21 and the first swing frame 22, the second fixed frame 41 and the second swing frame 42, and prevents separation and detachment between the first fixed frame 21 and the first swing frame 22, the second fixed frame 41 and the second swing frame 42.

[0040] The vibration device for abrasive grinding wheels, in use, involves installing the abrasive grinding wheel inside the grinding mechanism 5. The upper and lower grinding discs are enclosed by a connecting cylinder 51 and a lower grinding disc 53, concentrating and discharging the abrasive dust generated during grinding to prevent dust from flying. The drive shaft of the grinding disc is installed and inserted through the connecting port 54, fixing the grinding mechanism 5 at the center of the support structure 1. This ensures the effective crushing and grinding of agglomerated abrasive by the upper and lower grinding discs 52 and 53. The grinding mechanism 5 has an inlet pipe 6 and an outlet pipe 7 connected to its upper and lower ends, respectively, for feeding and discharging the grinding discs inside. The top end of the inlet pipe 6 is connected to the upper swing mechanism 2, and the bottom end of the outlet pipe 7 is connected to the lower swing mechanism 4. Several second electric push rods 43 are connected between the second fixed frame 41 and the second swing frame 42 of the lower swing mechanism 4. An elliptical hammer plate 44 is fitted at the bottom. The elliptical hammer plate 44 is driven to oscillate eccentrically by the rotation of the eccentric shaft 45, which rotates and impacts the second swing frame 42, causing vibration on the second swing frame 42. The vibration and shaking of the second swing frame 42 drive the discharge pipe 7 to shake and vibrate, so that the ground abrasive inside the discharge pipe 7 can be discharged quickly. A screen can be installed at the bottom of the discharge pipe 7 to screen out the abrasive by shaking and vibration of the discharge pipe 7. At the same time, a swing rod 3 is connected to the second connecting ear 48 at the upper end of the second swing frame 42. The middle part of the swing rod 3 is connected to the grinding mechanism 5, and the upper end of the swing rod 3 is connected to the first swing frame 22. The vibration and shaking on the second swing frame 42 are directed to the first swing frame 22. The vibration and shaking frequency generated by the shaking of the first swing frame 22 is used to convey the abrasive inside the feed pipe 6 connected to the upper swing mechanism 2 downward, avoiding abrasive accumulation and ensuring the production and processing of the grinding wheel.

[0041] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
