Description

Technical Field

[0001] This utility model relates to the field of ceramic spherical blank processing technology, and in particular to a surface finishing device for large-size ceramic spherical blanks. Background Technology

[0002] The processing of ceramic balls mainly includes the sintering of ceramic ball blanks, pre-rounding of ceramic ball blanks, grinding and polishing, etc., to gradually improve the sphericity and surface quality. The working principle of ceramic ball grinding is that during grinding, under the action of processing load, the grinding wheel drives the ceramic ball blank to revolve along the annular groove of the cast iron disc, while the ball blank rotates on its own axis. As the ceramic ball circulates between the grinding disc groove and the ball conveying device, the ball blank is ground evenly.

[0003] In existing technologies, when repairing and grinding ceramic blanks, only one ceramic blank can be processed at a time. Moreover, the operator needs to raise their arm and slowly move the grinding tool upward to process the rotating ceramic blank. This not only reduces grinding efficiency but also causes discomfort to the arm during prolonged grinding. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, when repairing and grinding ceramic spherical blanks, only one ceramic spherical blank can be processed simply, and the operator needs to raise his arm to slowly move the grinding tool upward to process the rotating ceramic spherical blank. This not only reduces the grinding efficiency, but also causes discomfort to the arm after grinding for a long time. Therefore, a surface finishing device for large-size ceramic spherical blanks is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface finishing device for large-size ceramic spherical blanks includes a base and a connecting plate, wherein the connecting plate is fixedly connected between two of the bases;

[0007] Two vertical plates are fixedly connected to the two bases respectively. Limiting plates are fixedly connected to the vertical plates respectively. A sliding groove is opened at the end of the limiting plate away from the vertical plate. A rotating rod is slidably connected between the two sliding grooves. A hinge plate is hinged to both ends of the rotating rod. A grinding component is installed between the two hinge plates. The grinding component includes a sleeve, a sliding rod, a pull plate, a pressing rod, and a circular cavity. The two sleeves are respectively hinged to the hinge plates. One end of each of the two sliding rods is slidably connected inside the sleeve. The pull plate is fixedly connected to one of the sliding rods. The circular cavity is fixedly connected to one of the sleeves. One end of the pressing rod is fixedly connected to the pull plate. The other end of the pressing rod is slidably connected inside the circular cavity. The circular cavity is connected to the other sleeve through a connecting pipe.

[0008] Preferably, the grinding component further includes screws and a fixing plate, the fixing plate being fixedly connected to one of the sleeves, the pressing rod being slidably connected to the fixing plate, and the two screws being fixedly connected to the end of the sliding rod away from the sleeve.

[0009] Preferably, a spring is provided between the slide rod and the inner wall of the sleeve.

[0010] Preferably, a sealing cylinder is fixedly connected to one of the bases, a support rod is slidably connected inside the sealing cylinder, and a tray is fixedly connected to the upper end of the support rod.

[0011] Preferably, a baffle is fixedly connected between the two limiting plates, an airbag is fixedly connected between the baffle and the rotating rod, and the airbag is connected to the sealing cylinder through a connecting pipe.

[0012] Preferably, a piston rod is slidably connected to the side wall of the sealing cylinder, and the piston rod is slidably connected to the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Pull the pull plate located on the top side of the tray with your finger. Pulling the pull plate will cause the fixedly connected slide rod to slide inside the sleeve until the scraper contacts the ceramic ball blank on the turntable near the tray and grinds the ceramic ball blank.

[0015] The pull plate can pull the extrusion rod to move. The end of the extrusion rod away from the pull plate moves in the cavity and squeezes the gas in the cavity through the connecting pipe into another sleeve. This pushes the slide rod, screw and scraper in the sleeve to move. At this time, the two scrapers move away from each other synchronously until they intercept and grind the ceramic blanks on the two turntables respectively, so as to achieve the effect of grinding the two ceramic blanks at the same time and speed up the grinding efficiency of the ceramic blanks.

[0016] When the arm pushes the sleeve upward, the hinge plate can push the rotating rod to slide in the groove on the limit plate and compress the airbag. The gas in the airbag flows into the sealing cylinder through the connecting pipe and pushes the support rod and the tray upward. At this time, the upward movement of the tray can support the arm and avoid discomfort caused by raising the arm for a long time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 A surface finishing device for large-size ceramic spherical blanks includes a base 1 and a connecting plate 8, with the connecting plate 8 fixedly connected between two bases 1.

[0025] Two vertical plates 5 are fixedly connected to two bases 1, and limit plates 10 are fixedly connected to the vertical plates 5. A sliding groove is formed at the end of the limit plate 10 away from the vertical plate 5. The sliding groove is horizontally positioned, and a rotating rod 14 is slidably connected between the two sliding grooves. The rotating rod 14 can both slide and rotate within the sliding groove. Hinge plates 6 are hinged to both ends of the rotating rod 14. A grinding component is installed between the two hinge plates 6. The grinding component includes a sleeve 7, a sliding rod 19, a pull plate 17, a pressing rod 15, and a cavity 16. The two sleeves 7 are respectively hinged to... On the hinge plate 6, one end of each of the two slide rods 19 is slidably connected to the sleeve 7. The outer surface of the slide rod 19 is slidably connected to the inner wall of the sleeve 7. The pull plate 17 is fixedly connected to one of the slide rods 19. The circular cavity 16 is fixedly connected to one of the sleeves 7. One end of the extrusion rod 15 is fixedly connected to the pull plate 17. The other end of the extrusion rod 15 is slidably connected to the circular cavity 16. The outer surface of the extrusion rod 15 is slidably connected to the inner wall of the circular cavity 16. The circular cavity 16 is connected to the other sleeve 7 through the connecting pipe 20.

[0026] The grinding component also includes a screw 18 and a fixing plate 4. The fixing plate 4 is fixedly connected to one of the sleeves 7. The pressing rod 15 is slidably connected to the fixing plate 4. The two screws 18 are respectively fixedly connected to the end of the slide rod 19 away from the sleeve 7. A spring is provided between the slide rod 19 and the inner wall of the sleeve 7.

[0027] A sealing cylinder 21 is fixedly connected to one of the bases 1. A support rod 9 is slidably connected inside the sealing cylinder 21. A tray 3 is fixedly connected to the upper end of the support rod 9. A baffle 11 is fixedly connected between the two limiting plates 10. An airbag 12 is fixedly connected between the baffle 11 and the rotating rod 14. The airbag 12 is connected to the sealing cylinder 21 through a connecting pipe 13. A one-way valve is installed on the connecting pipe 13. A piston rod 22 is slidably connected to the side wall of the sealing cylinder 21. The piston rod 22 is slidably connected to the base 1. The piston rod 22 can seal the sealing cylinder 21.

[0028] In this invention, when in use, two ceramic blanks are first placed on turntable 2 respectively. An external servo motor drives turntable 2 to rotate, which in turn drives the ceramic blanks to rotate continuously. Then, the matching scraper is threaded onto screw 18. The operator places his arm on tray 3 and pulls the pull plate 17 located on the upper side of tray 3 with his fingers. Pulling the pull plate 17 causes the fixedly connected slide rod 19 to slide inside sleeve 7 until the scraper contacts the ceramic blank on turntable 2 near tray 3 and grinds the ceramic blank.

[0029] When the pull plate 17 located on the upper side of the tray 3 is pulled to move closer to the ceramic blank, the pull plate 17 can pull the extrusion rod 15 to move. The end of the extrusion rod 15 away from the pull plate 17 moves in the cavity 16 and squeezes the gas in the cavity 16 through the connecting pipe 20 into another sleeve 7, and pushes the slide rod 19, screw 18 and scraper in the sleeve 7 to move. At this time, the two scrapers move away from each other synchronously until they intercept and grind the ceramic blanks on the two turntables 2 respectively. When the pull plate 17 is pushed to reset, the extrusion rod 15 resets. When it stops squeezing the gas in the cavity 16, the slide rod 19 will reset under the tension of the spring. Therefore, the effect of the two scrapers moving away or moving closer to each other synchronously is achieved, and the effect of grinding two ceramic blanks at the same time is achieved, which speeds up the grinding efficiency of the ceramic blanks.

[0030] Simultaneously, when the arm pushes the sleeve 7 upward, the hinge plate 6 can push the rotating rod 14 to slide in the groove on the limiting plate 10 and compress the airbag 12. The gas in the airbag 12 flows into the sealing cylinder 21 through the connecting pipe 13 and pushes the support rod 9 and the tray 3 upward. At this time, the upward movement of the tray 3 can support the arm. When the grinding is completed, the piston rod 22 is pulled away from the sealing cylinder 21. At this time, the gas in the sealing cylinder 21 is discharged and the tray 3 falls naturally.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
