[0031] When quasi-spherical core needs to be polished, at this time, workers can place the quasi-spherical core to be polished in the mold, and start electric push rod 125, promote the front end of swing frame 121 to swing upwards, when the mold containing quasi-spherical core is placed on the upper surface of grinding component 11, the moving end of electric push rod 125 drives the front end of swing frame 121 to descend, so that the bottom of the front end of swing frame 121 is located at the center of the mold, when the output shaft of first motor 122 drives extrusion rod 123 to rotate, the outer surface of the rear end of extrusion rod 123 extrudes the inside of the rear side of swing frame 121, so that swing frame 121 reciprocates on the upper surface of swing component 12, at this time, the front end of swing frame 121 can drive the mold to swing on the upper surface of grinding component 11, promote grinding component 11 to rotate to grind quasi-spherical core in the inside of the mold.
[0032] When different radii of quasi-spherical cores need to be polished, the bottom end of the threaded rod 124 can be rotated at this time to cause the extrusion rod 123 to slide inside the output shaft of the first motor 122, change the rotation radius of the extrusion rod 123 driven by the first motor 122, thereby changing the extrusion distance of the extrusion rod 123 to the swing frame 121, further changing the radius of the reciprocating swing of the swing frame 121, and according to different quasi-spherical cores for polishing, the rear side of the swing assembly 12 can be lifted upward, so that the rear side of both ends of the swing assembly 12 slides upward in the sliding groove of the arc-shaped disc 126, and the rear side of the swing assembly 12 is lifted upward. When the swing assembly 12 is lifted upward, the swing frame 121 is also moved, so that the swing frame 121 can move the mold at different angles.
[0033] As described in the background, in the process of using the grinding device to polish the quasi-spherical core, debris particles will be generated, if these particles cannot be removed in time, they may reattach to the surface of the quasi-spherical core being processed, causing surface defects such as scratches and pits, thereby affecting the smoothness and precision of the finished product, in addition, the residual particles may also cause excessive wear or irregular wear in the local area during the grinding process, reducing the consistency and repeatability of the processing.
[0034] Reference is made to the accompanying drawings Figures 2-4To solve the problem of residual debris particles, the embodiment adopts the technical scheme as follows: the outer surface of the grinding assembly 11 is rotationally connected with a protective shell 24, the protective shell 24 is used for blocking the debris particles generated during grinding, the lower surface of the protective shell 24 is symmetrically and throughly provided with a plurality of liquid outlet holes, the upper surfaces of the two sides of the protective shell 24 are fixedly connected with sliding rails 22, the inner sides of the sliding rails 22 are rotationally connected with first screws 23, the rear ends of the first screws 23 are fixedly connected with transmission wheels 28, the transmission wheels 28 are used for driving the first screws 23 to rotate, the outer surfaces of the transmission wheels 28 are transmissionally connected with a belt 21, the belt 21 is used for driving the transmission wheels 28 to rotate at the same time, the right end of the belt 21 penetrates through the right side of the shell 14, the right side of the shell 14 is fixedly connected with a second motor 2, the right end of the belt 21 is transmissionally connected to the outer surface of the output shaft of the second motor 2, the second motor 2 is used for driving the belt 21 to transmission, the outer surfaces of the rear ends of the first screws 23 are threadedly connected with sliding blocks 27, the outer surfaces of the bottoms of the sliding blocks 27 are slidingly connected to the inner sides of the sliding rails 22, the first screws 23 are used for causing the sliding blocks 27 to slide back and forth on the inner sides of the first screws 23, the ends of the adjacent sliding blocks 27 close to each other are slidingly connected with telescopic rods 26, the lower surfaces of the ends of the telescopic rods 26 close to each other are rotationally connected with first scraping pieces 25, the sliding blocks 27 are used for driving the first scraping pieces 25 to move through the telescopic rods 26, the rear sides of the first scraping pieces 25 are slidingly connected to the outer surfaces of the protective shell 24, the front sides of the bottoms of the protective shell 24 are throughly connected with discharge pipes 291, the outer surfaces of the discharge pipes 291 are throughly connected to the front side of the frame 1, the discharge pipes 291 are used for guiding the debris particles, and the front side of the frame 1 is detachably connected with a collecting box 29, the collecting box 29 is used for collecting the particles.
[0035] When the swing assembly 12 grinds the ball core, the protective shell 24 can block the debris particles generated during grinding, prevent them from spreading, and make the debris concentrate and fall into the inside of the protective shell 24, and the cutting fluid will be discharged through the liquid outlet holes in the bottom of the protective shell 24.
[0036] When the second motor 2 starts, its output shaft drives the transmission wheel 28 to rotate through the belt 21, thereby driving the first screw rod 23 fixedly connected with the transmission wheel 28 to rotate synchronously. When the first screw rod 23 rotates, the sliding block 27 slides forward on the inner side of 22. When the sliding block 27 slides, it drives the first scraping piece 25 to slide synchronously through the telescopic rod 26. Since the rear side of the first scraping piece 25 is slidingly connected to the outer surface of the top of the protective shell 24, the first scraping piece 25 slides along the outer surface of the protective shell 24. During the sliding process of the first scraping piece 25, the bottom of the first scraping piece 25 extrudes the particles in the interior of the protective shell 24, thereby facilitating the particles to be transported forward on the inner side of the protective shell 24, so that the particle residues generated in the grinding process in the interior of the protective shell 24 can be effectively scraped off, thereby preventing the particles from flying and adhering again, and significantly improving the surface quality and processing consistency of the workpiece.
[0037] When the particles are transported to the front end of the protective shell 24, they are discharged through the discharge pipe 291 arranged on the bottom front side of the protective shell 24 and enter the collection box 29 through the discharge pipe 291 connected through the front side of the frame body 1, thereby completing the centralized collection of the particles and facilitating subsequent cleaning operations.
[0038] The interior of the protective shell 24 is fixedly connected with a guide ring 241. A plurality of liquid outlets are symmetrically and throughly arranged on the bottom of the guide ring 241. The liquid outlets of the guide ring 241 and the liquid outlets of the protective shell 24 are mutually through. The upper surface of the guide ring 241 is outwardly inclined. When the oscillating assembly 12 grinds the ball core, the protective shell 24 can effectively block the generated particles and prevent their diffusion. At the same time, the particles and the cutting fluid fall together on the upper surface of the guide ring 241 in the interior of the protective shell 24. Since the upper surface of the guide ring 241 is outwardly inclined, the particles slide down to the inner wall of the bottom of the protective shell 24 under the action of gravity, and the cutting fluid is discharged through the liquid outlets symmetrically arranged on the bottom of the guide ring 241 and communicated with the liquid outlets of the protective shell 24, thereby realizing the effective separation of the particles and the cutting fluid and further improving the recycling purity and the reusability of the cutting fluid.
[0039] When the particles on the inner side of the protective shell 24 are collected, the output shaft of the second motor 2 drives the transmission wheel 28 to rotate reversely through the belt 21. When the transmission wheel 28 reverses, it drives the sliding block 27 to slide backward through the first screw rod 23. When the sliding block 27 slides backward, it drives the first scraping piece 25 to slide simultaneously through the telescopic rod 26, so that the first scraping piece 25 can move backward along the outer surface of the top of the protective shell 24.
[0040] When the first scraping piece 25 scrapes the particles in the interior of the protective shell 24, the particles are easy to slide into the liquid outlets on the lower surface of the protective shell 24, thereby causing the liquid outlets to be gradually blocked and further affecting the discharge efficiency of the cutting fluid.
[0041] Reference is made to the accompanying drawings Figures 5-6 In order to solve the problem that the particles block the liquid outlet hole on the lower surface of the protective shell 24, the technical scheme is adopted in the embodiment: the side of the adjacent sliding blocks 27 away from each other is fixedly connected with a rack 3, the sliding block 27 is used to drive the rack 3 to move forward and backward, the rear side of both ends of the protective shell 24 is rotatably connected with a rotating rod 32, the top end of the rotating rod 32 is fixedly connected with a gear 31, the gear 31 is used to drive the rotating rod 32 to rotate, the side of the rack 3 away from each other is in meshing cooperation with the outer surface of the gear 31, the bottom end of the rotating rod 32 is fixedly connected with a second screw rod 33, the outer surfaces of the adjacent second screw rods 33 are threadedly connected with a lifting frame 34, the two sides of the front end of the lifting frame 34 are slidably connected to the outer surface of the protective shell 24, the second screw rod 33 is used to drive the lifting frame 34 to move up and down, the upper surface of the lifting frame 34 is fixedly connected with a plurality of blocking pieces 35 in symmetry, and the top end of the blocking piece 35 is used to block the liquid outlet hole at the bottom of the protective shell 24.
[0042] In the process that the sliding block 27 slides forward to drive the first scraping piece 25 to scrape the debris in the protective shell 24, at this time, the sliding block 27 drives the rack 3 to move at the same time, when the rack 3 moves backward, the side of the rack 3 away from each other is in meshing cooperation with the outer surface of the gear 31, and the gear 31 is rotated, and when the gear 31 rotates, the second screw rod 33 is driven to rotate at the same time through the rotating rod 32.
[0043] The synchronous rotation of the two second screw rods 33 drives the lifting frame 34 threadedly connected therewith to move upward, and the blocking pieces 35 fixed on the lifting frame 34 also rise, when the blocking piece 35 reaches the specified position, the top end of the blocking piece 35 is inserted into the liquid outlet hole at the bottom of the protective shell 24, the sealing operation of the liquid outlet hole is completed, so that the debris is prevented from entering the cutting fluid discharge channel in the process of scraping, and the problems of cutting fluid pollution and liquid outlet hole blockage are avoided.
[0044] The front end of the two sides of the lifting frame 34 is fixedly connected with a guide piece 36, the lifting frame 34 is used to drive the guide piece 36 to move up and down, the inner side of the bottom of the protective shell 24 is slidably connected with a sealing plate 37, the sealing plate 37 is used to block the bottom of the protective shell 24, the two ends of the front side of the sealing plate 37 are slidably connected between the inner sides of the guide pieces 36, the inner sides of the guide pieces 36 are in extrusion cooperation with the two ends of the front side of the sealing plate 37, and the guide piece 36 is used to drive the sealing plate 37 to slide forward and backward.
[0045] When the particles inside the protective shell 24 are scraped off, the sealing plate 37 can block the front side of the bottom of the protective shell 24 at this time, preventing the cutting fluid from entering the inside of the discharge pipe 291. When the first scraping piece 25 scrapes the particles inside the protective shell 24, the lifting frame 34 moves the guide piece 36 upward, and as the guide piece 36 moves upward, it exerts a pushing force on both ends of the front side of the sealing plate 37, causing the sealing plate 37 to slide forward and open the passage between the bottom of the protective shell 24 and the discharge pipe 291. As the first scraping piece 25 moves the particles to the front end inside the protective shell 24, the particles can pass through the open passage into the discharge pipe 291 and finally fall into the collection box 29 for centralized collection.
[0046] When the particles are cleaned up, the sliding block 27 slides the rack 3 backward, and the engagement between the rack 3 and the gear 31 causes the gear 31 to rotate in the opposite direction. When the gear 31 rotates in the opposite direction, it drives the second screw 33 to rotate in the opposite direction through the rotating rod 32. When the second screw 33 rotates in the opposite direction, it drives the lifting frame 34 to move the blocking piece 35 downward, causing the blocking piece 35 to disengage from the liquid outlet hole at the bottom of the protective shell 24, allowing the liquid outlet hole at the bottom of the protective shell 24 to discharge cutting fluid again. When the lifting frame 34 moves downward, it moves the guide piece 36, and when the guide piece 36 moves downward, it presses the sealing plate 37, causing the sealing plate 37 to slide backward and block the bottom of the protective shell 24, preventing the cutting fluid from flowing into the discharge pipe 291.
[0047] When the protective shell 24 blocks the cutting fluid and the debris particles generated during grinding, the debris particles and the cutting fluid that come into contact with the inner wall of the protective shell 24 are likely to splash, causing the particles to reattach to the surface of the quasi-spherical core being processed.
[0048] Reference is made to the accompanying drawings Figure 7To solve the problem of debris particles and cutting fluid splash, the embodiment adopts the following technical scheme: the front side of the outer surface of the protective shell 24 is symmetrically and fixedly connected with a fixed frame 401, the lower surfaces of the rear sides of the fixed frame 401 are rotatably connected with rotating pieces 4, the outer surfaces of the rotating pieces 4 are fixedly connected with buffer cloths 41, the rotating pieces 4 are used for winding the buffer cloths 41, the buffer cloths 41 are used for buffering the debris particles and the cutting fluid, the bottom ends of the buffer cloths 41 are slidably connected to the interiors of the buffer cloths 41, the ends away from each other of the buffer cloths 41 are fixedly connected to the outer surfaces of first scraping pieces 25, the first scraping pieces 25 are used for driving the one ends of the buffer cloths 41 to move synchronously, the outer surfaces of the top parts of the rotating pieces 4 are fixedly connected with torsion springs 43, the top ends of the torsion springs 43 are fixedly connected to the lower surfaces of the rear sides of the fixed frame 401, the torsion springs 43 are used for driving the rotating pieces 4 to rotate, and the sides away from each other of the fixed frame 401 are fixedly connected with second scraping pieces 42, the outer surfaces of the rear sides of the second scraping pieces 42 are in extrusion fit with the outer surfaces of the buffer cloths 41, and the second scraping pieces 42 are used for cleaning the particles adhered to the outer surfaces of the buffer cloths 41.
[0049] When the protective shell 24 blocks the debris particles and the cutting fluid generated during grinding, the substances will first contact and impact the surface of the buffer cloth 41. Since the buffer cloth 41 has a certain flexibility, it can effectively reduce the impact force of the debris and the cutting fluid, and play a preliminary buffering role to prevent the debris from splashing or the cutting fluid from scattering everywhere.
[0050] When the first scraping piece 25 slides forward to clean the debris inside the protective shell 24, the rear end of the buffer cloth 41 moves synchronously with the first scraping piece 25 and shrinks backward, at this time, the torsion spring 43 in the force storage state drives the rotating piece 4 to rotate, and the rotating piece 4 can wind the buffer cloth 41 when rotating.
[0051] During the winding of the buffer cloth 41, the outer surface of the buffer cloth 41 is closely attached to the second scraping piece 42 fixedly connected to the fixed frame 401, and the second scraping piece 42 can effectively scrape off the debris particles adhered to the surface of the buffer cloth 41 during this process, so as to keep the surface of the buffer cloth 41 clean, so that it can continuously and effectively play a blocking role, and the scraped particles can also enter the discharge pipe 291 to be collected, thereby improving the collection efficiency of the particles.
[0052] When the particle cleaning is completed, the first scraping piece 25 slides backward to reset, and drives the rear end of the buffer cloth 41 to gradually expand, with the expansion of the buffer cloth 41, the rotating piece 4 rotates, at the same time, the torsion spring 43 is driven to enter the force storage state again, so as to facilitate the subsequent winding of the buffer cloth 41 by the torsion spring 43.
