DETAILED DESCRIPTION

[0026] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example:

[0028] Please refer to the attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a bearing accessory grinder, such as Figure 1 As shown, one of its core components is a solid and stable workbench 1. The top of the workbench 1 is firmly fixed with an inclined bearing slide 2 through two strong and durable support rods 23. This inclined design utilizes the principle of gravity, so that the bearing accessories can slide down naturally, which is convenient for subsequent processing operations. Fixed material ports 3 are precisely opened on both sides of the inside of the bearing slide 2. Both sides of the bottom of the fixed material port 3 are flexibly installed to receive the movable shaft 4. The middle outer diameter of the movable shaft 4 is firmly fixed with rotating rollers 7. These rotating rollers 7 can not only provide stable support for the bearing accessories, but also cooperate with the bearing accessories to realize self-rotation during the subsequent grinding process, thereby improving the uniformity and comprehensiveness of the grinding.

[0029] Two straight guide rods 10 are firmly fixed to the rear side of the top of the workbench 1. The outer diameter of the guide rod 10 just matches the inner size of the mounting frame 11, so that the mounting frame 11 can move up and down smoothly on the guide rod 10, thereby adjusting the height of the grinding wheel to adapt to bearing accessories of different sizes. A first rotating shaft 12 is movably installed at a key position near the left feed port 3 inside the guide rod 10. A front grinding wheel 13 is tightly fixed to the front end of the first rotating shaft 12. The front grinding wheel 13 is made of high-quality grinding material. It is made of, has excellent wear resistance and grinding effect, and can effectively perform high-speed rotation grinding on the front side of the bearing accessory. The front end of the mounting frame 11 is close to the right-side fixing port 3, and a positioning frame 14 is firmly fixedly installed. The second rotating shaft 15 is accurately and movably installed inside the positioning frame 14. The outer diameters of both sides of the second rotating shaft 15 are firmly fixedly connected with side grinding discs 16. The design shape and angle of the side grinding discs 16 have been carefully optimized and can fit closely to the side of the bearing accessory, thereby ensuring the accuracy and quality of side grinding.

[0030] In this embodiment, the front ends of the movable shafts 4 on both sides are firmly fixed with the first synchronous wheels 5, and the outer diameters of the first synchronous wheels 5 are tightly connected by a tough and durable first synchronous belt 6. The combined design of the synchronous wheels and the synchronous belt can ensure the synchronous rotation of the movable shafts 4 on both sides, thereby ensuring the stability and uniformity of the bearing accessories during the grinding process. The rear ends of the two inner movable shafts 4 are firmly fixed with the second synchronous wheels 8, and the outer diameters of the second synchronous wheels 8 are connected by a second synchronous belt 9 of the same reliable quality, which further enhances the transmission stability and coordination between the movable shafts 4.

[0031] Furthermore, a powerful DC motor 17 is firmly fixed on the front end of the mounting frame 11, a first driving gear 18 is tightly fixed on the driving end of the DC motor 17, a first driven gear 19 is accurately fixed on the front outer diameter of the first rotating shaft 12, and the first driven gear 19 is precisely meshed and connected with the inner end of the first driving gear 18. When the DC motor 17 is started, the meshing transmission of the gears can stably drive the first rotating shaft 12 to rotate, thereby driving the front grinding wheel 13 to rotate at high speed, providing strong power support for the front grinding of the bearing accessories.

[0032] The rear ends of the first rotating shaft 12 and the second rotating shaft 15 are precisely extended to the rear side of the mounting frame 11, and are firmly fixedly connected with the third synchronous wheel 20. The outer diameters of the third synchronous wheel 20 are connected by a tough third synchronous belt 21. This design enables the first rotating shaft 12 and the second rotating shaft 15 to achieve synchronous rotation, ensuring that during the grinding process, the front grinding wheel 13 and the side grinding disc 16 work together to improve the grinding efficiency and quality.

[0033] A third rotating shaft 22 is flexibly and movably mounted on one side of the bottom of the mounting frame 11 near the fixing port 3, a second driven gear 25 is firmly fixedly mounted on the rear end of the third rotating shaft 22, a second driving gear 24 is firmly fixedly mounted on the rear outer diameter of the second rotating shaft 15, and the second driving gear 24 is precisely meshed and connected with the inner end of the third rotating shaft 22, a transmission shaft 27 is movably mounted on the front end of the third rotating shaft 22 through a flexible and reliable universal joint 26, and the front end of the transmission shaft 27 is also firmly connected to the rear end of the rightmost movable shaft 4 through the universal joint 26, through such a complex and precise transmission structure design, linkage between multiple rotating shafts can be achieved, so that the bearing accessories can not only rotate by themselves during the grinding process, but also accurately cooperate with the rotation of the grinding wheel, thereby ensuring the uniformity and comprehensiveness of the grinding.

[0034] A lifting cylinder 28 is firmly fixedly installed in the middle of the top of the workbench 1, and a U-shaped frame 29 is firmly fixedly installed on the driving end of the lifting cylinder 28. One side of the top of the U-shaped frame 29 is tightly fixedly installed on the bottom end of the guide rod 10, and a top frame 30 is firmly fixedly installed on the other side of the top of the U-shaped frame 29. The two ends of the top frame 30 extend precisely to the bottom of the two material fixing ports 3 respectively, and are firmly fixedly connected with a top block 31. The lifting cylinder 28 can accurately control the lifting and lowering of the U-shaped frame 29, thereby driving the mounting frame 11 and the top frame 30 to move up and down, realizing the descending grinding of the grinding wheel and the lifting and lowering operation of the top block 31, ensuring the stable positioning of the bearing accessories during the grinding process and the smooth entry and exit of the material fixing port 3.

[0035] A side frame 32 is firmly fixedly connected to one side of the bearing slide 2, a rotating rod 33 is flexibly and movably installed in the middle of the side frame 32, a swing frame 34 is firmly fixedly connected to the outer diameter of the rotating rod 33, baffles 36 are flexibly and movably installed on both sides of the swing frame 34, and a fixed plate 35 is firmly fixedly connected to the front end of the side frame 32 near the lower side of the rotating rod 33. The bottom ends of the baffles 36 accurately penetrate the interior of the fixed plate 35 and extend to the bottom of the baffle 36. The design of this baffle and swing frame ingeniously realizes intermittent transportation of bearing accessories. Through the control of the electric cylinder 38, the baffle 36 can be alternately raised and lowered, and only one bearing accessory is allowed to enter the fixed material port 3 at a time, avoiding uneven grinding or equipment failure caused by multiple accessories entering at the same time, thereby improving the reliability and accuracy of the entire grinding work.

[0036] A bracket 37 is also firmly fixedly connected to one side of the bearing slide 2 near the side frame 32. An electric cylinder 38 is firmly fixedly installed on the top of the bracket 37. The end of the electric cylinder 38 is flexibly installed on the top of the swing frame 34. The electric cylinder 38 serves as a power source and can accurately control the swing of the swing frame 34, thereby realizing the alternating lifting and lowering of the baffle 36, providing stable and reliable power support for the intermittent transportation of bearing accessories.

[0037] Working principle:

[0038] First, the staff carefully places the bearing parts to be polished on the bearing slide 2 one by one. Since the bearing slide 2 is inclined, the bearing parts will naturally slide downward along the slide direction under the action of gravity. During the sliding process, the bearing parts will be blocked by the baffle 36 on the left. At this time, the electric cylinder 38 is started. When the electric cylinder 38 controls the internal telescopic rod to perform precise reciprocating extension and retraction, it will drive the swing frame 34 to swing back and forth smoothly around the rotating rod 33. The reciprocating swinging swing frame 34 will drive the baffles 36 on both sides to rise and fall alternately. When the baffle 36 on the left rises, , the right baffle 36 descends, the first bearing accessory will slide smoothly into between the two baffles 36 and be accurately blocked by the right baffle 36; when the right baffle 36 rises, the left baffle 36 descends, the second bearing accessory will be blocked by the left baffle 36, and at the same time, the right baffle 36 releases the blocking effect on the first bearing accessory, and the first bearing accessory will be smoothly fed into the left fixed material port 3, and this cycle is repeated to achieve intermittent delivery of all bearing accessories, providing a stable and orderly material supply for subsequent grinding work, greatly improving the grinding accuracy and quality,

[0039] When the bearing accessory comes to the fixed material port 3 on the left, it will accurately fall onto the top block 31 in the fixed material port 3. At this time, the DC motor 17 is started, and the first driving gear 18 is driven by the DC motor 17 to rotate stably. The first driving gear 18 drives the first driven gear 19 and the first rotating shaft 12 meshing therewith to rotate synchronously, thereby driving the front grinding wheel 13 to rotate at high speed, providing powerful power for the front grinding of the bearing accessory. Subsequently, the lifting cylinder 28 controls the internal piston rod to accurately descend, driving the U-shaped frame 29 to descend smoothly. When the U-shaped frame 29 descends, it will drive the mounting frame 11 to descend synchronously, so that the front grinding wheel 13 can be accurately descended and closely attached to the surface of the bearing accessory for efficient grinding. At the same time, when the U-shaped frame 29 descends, it will also drive the top frame 30 to descend, and the top frame 30 drives the top block 31 to descend, so that the bearing accessory is stably supported by the two rotating rollers 7, ensuring that the position of the bearing accessory is stable and unchanged during the grinding process.

[0040] When the first rotating shaft 12 rotates, it will also drive the third synchronous wheel 20 on the rear side to rotate synchronously. The precise transmission of the third synchronous belt 21 is used to drive the second rotating shaft 15 to rotate. When the second rotating shaft 15 rotates, it will drive the second driving gear 24 to rotate. Through the precise transmission of the second driving gear 24 and the second driven gear 25, the third rotating shaft 22 is driven to rotate in the opposite direction. The third rotating shaft 22 drives the transmission shaft 27 to rotate through the universal joint 26, thereby driving the movable shaft 4 on the rear side to rotate. When the movable shaft 4 on the rear side rotates, the two movable shafts 4 below the right-side fixed material opening 3 are driven to rotate synchronously through the reliable transmission of the first synchronous wheel 5 and the first synchronous belt 6. Then, the stable transmission of the second synchronous wheel 8 and the second synchronous belt 9 is used to drive the two movable shafts 4 below the left-side fixed material opening 3 to rotate. When the two movable shafts 4 rotate, the bearing accessories will be driven to rotate stably. The high-speed rotating front grinding wheel 13 and the non-stop rotating bearing accessories are used to achieve efficient, uniform and fine grinding of the front side of the bearing outer ring, thereby greatly improving the grinding efficiency and quality.

[0041] After grinding is completed, the lifting cylinder 28 controls the top frame 30 and the top block 31 to rise accurately, and the polished bearing accessories are smoothly pushed out of the bearing slide 2, and slide along the bearing slide 2 to the dosing port 3 on the right. At the same time, the next bearing accessory accurately enters the dosing port 3 on the left, and then the above operation is repeated to ensure the continuity and stability of the grinding work.

[0042] When the bearing accessory enters the fixing port 3 on the right, the DC motor 17 and the lifting cylinder 28 are started again. The first rotating shaft 12 drives the second rotating shaft 15 to rotate through the precise transmission of the third synchronous wheel 20 and the third synchronous belt 21, thereby driving the two side grinding discs 16 to rotate at high speed. Similarly, the bearing accessory itself uses the rotating movable shaft 4 to rotate stably, which is conducive to the high-speed rotating side grinding disc 16 to cooperate with the rotating bearing accessory to achieve accurate and efficient grinding of the side of the bearing accessory, ensuring that the side of the bearing accessory can also be evenly and finely polished. After completion, the lifting cylinder 28 lifts the bearing accessory to make it slide out along the bearing slide 2. The entire grinding process has a high degree of automation, is easy to operate, and has excellent grinding effect.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
