Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing and design, in particular to a grinding machine for processing vibration motor bearings. Background Art

[0002] Vibration motor bearings are one of the important components of vibration screening equipment. Their quality directly affects the service life of the screening equipment. During the manufacturing process of the bearings, the inner and outer rings of the bearings must be ground to reduce the friction coefficient of the inner and outer rings of the bearings and reduce the friction coefficient during the rotation of the bearings, thereby ensuring the stability of the bearing operation.

[0003] The applicant has found that when processing the inner circle of the bearing, it is necessary to fix it to avoid the outer ring of the bearing from shifting during grinding. For example, Patent No. CN213197076U discloses an internal cylindrical grinder for processing precision bearings. Through a fixing ring and a positioning spring, the device can facilitate the handling of bearings of different sizes, greatly improving the versatility of the device and avoiding the problem of product quality degradation caused by replacing the fixture. However, this solution still has certain shortcomings. The above solution is relatively laborious to fix by manual screws, and it is relatively inconvenient to fix. It is necessary to overcome the spring force for initial positioning and then use the screw for enhanced positioning. There are many steps and it is impossible to complete the clamping quickly in one step. At the same time, there is no limit on the top of the bearing, which cannot meet the use requirements. Therefore, the applicant needs to design a grinder for vibration motor bearing processing to solve the problem. Utility Model Content

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The utility model adopts the clamping component design to place the bearing at a suitable position on the top of the bed, then starts the motor to drive the large bevel gear to rotate, and the large bevel gear drives the four small bevel gears to rotate, so that the four screw rods rotate together, thereby causing the moving block to move together, and the four arc-surface clamping plates to move together through the curved rod, and finally clamp the four sides of the bearing.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1 to 5 A grinding machine for processing vibration motor bearings includes a bed 1, a grinding frame 2 is fixed on the top of the bed 1, and the grinding frame 2 is provided with a lifting plate 3 installed on the grinding frame 2 through a hydraulic rod. An electric grinding disc 5 and a pressing assembly 8 are installed at the bottom of the lifting plate 3, and a dust collection assembly 4 is installed on the inside of the grinding frame 2. A clamping assembly 6 is installed on the bed 1, and the clamping assembly 6 includes four screw rods 61 rotatably connected to the inner cavity of the bed 1. The four screw rods 61 are designed to be perpendicular to each other, and a small bevel gear 62 is docked at one end of the screw rod 61, and the small bevel gear 62 is engaged with a large bevel gear 63. The large bevel gear 63 is rotatably connected to the bottom end of the inner cavity of the bed 1, and the motor 7 fixed at the bottom of the bed 1 is docked with the rotating shaft of the large bevel gear 63. A moving block 64 is threadedly connected to the screw rod 61, and a curved rod 65 at the top of the moving block 64 is installed with a curved splint 66.

[0024] As mentioned above, through the design of the clamping component 6, when the clamping is stable, the bearing is placed in a suitable position on the top of the bed 1, and then the motor 7 is started to drive the large bevel gear 63 to rotate, and the large bevel gear 63 drives the four small bevel gears 62 to rotate, so that the four screw rods 61 rotate together, thereby causing the moving block 64 to move together, and the four arc-surface clamps 66 are driven to move together through the curved rod 65, and finally the four sides of the bearing are clamped. This clamping is very firm and the operation is completed in one step, which effectively improves the speed and efficiency of the clamping work. Then the hydraulic rod is started to move the electric grinding disc 5 on the lifting plate 3 to the inner circle of the bearing for grinding. Note that the curved rod 65 is limited and slides in the opening of the bed 1.

[0025] Reference Figure 5 The bottom surface of the arc-surface splint 66 is provided with three ball grooves, and the inside of the ball groove is connected with steel balls 69, and the steel balls 69 roll on the top surface of the bed body 1. An opening block 67 is fixed on one side of the arc-surface splint 66, and the opening block 67 is inserted by the curved rod 65, and the opening block 67 and the curved rod 65 are fixedly connected with bolts.

[0026] As described above, the design of the clamping assembly 6 is further optimized. During installation, the opening block 67 is fixed on the outside of the curved rod 65, which makes it easy to disassemble and replace the curved splint 66. The steel ball 69 makes the curved splint 66 more stable when moving, which is very practical.

[0027] Reference Figures 1 to 2 The pressing assembly 8 includes two guide rods 81 passing through the sliding holes of the lifting plate 3. The guide rods 81 are located on both sides of the electric grinding disc 5, and a pressure ring plate 82 is fixed to the bottom of the guide rod 81. The pressure ring plate 82 and the bottom of the lifting plate 3 are connected with a spring 83 sleeved on the outside of the guide rod 81. The bottom surface of the pressure ring plate 82 and the clamping surface of the arc clamping plate 66 are both bonded with rubber pad 1 84 and rubber pad 2 68. The electric grinding disc 5 is designed to pass through the ring opening of the pressure ring plate 82 and enter the inner circle of the bearing, and the height of the electric grinding disc 5 is higher than the pressure ring plate 82.

[0028] As described above, by pressing the solid component 8, the bearing stability is further optimized in design. When it is fixed for grinding, the hydraulic rod on the grinding frame 2 is started to drive the lifting plate 3 to descend, and the pressure ring plate 82 first contacts the top surface of the bearing. As the pressure ring plate 82 further descends, the guide rod 81 slides on the lifting plate 3 and compresses the spring 83. Then the electric grinding disc 5 passes through the ring mouth of the pressure ring plate 82 and enters the inner circle of the bearing for grinding. At this time, the top surface of the bearing is also well fixed, further improving the processing stability. The rubber pad 1 84 and the rubber pad 2 68 can use elasticity to enhance the extrusion force while avoiding wear caused by direct contact.

[0029] Reference Figures 1 to 2The dust collection component 4 includes a collection box 41 fixed on the inner side of the grinding frame 2. A suction pipe is provided on one side of the collection box 41 and a filter 42 is fixed inside. The collection box 41 and the grinding frame 2 are provided with corresponding openings, and a fan 43 is installed on the outer wall of the grinding frame 2 at the opening position.

[0030] As mentioned above, through the dust collection component 4, in the optimized design of the working environment, the fan 43 is started during the operation, so that a negative pressure is generated inside the collection box 41, and the dust generated by grinding is sucked in through the suction tube and then filtered through the filter 42, thereby preventing the dust from affecting the working environment.

[0031] The operating principle of the present invention is now described as follows:

[0032] When the present invention is used, first place the bearing in a suitable position on the top of the bed 1, then start the motor 7 to drive the large bevel gear 63 to rotate, and the large bevel gear 63 drives the four small bevel gears 62 to rotate, so that the four screw rods 61 rotate together, thereby causing the moving block 64 to move together, and the four arc-surface clamping plates 66 to move together through the curved rod 65, and finally clamp the four sides of the bearing, start the hydraulic rod on the grinding frame 2 to drive the lifting plate 3 to descend, the pressure ring plate 82 first contacts the top surface of the bearing, as the pressure ring plate 82 further descends, the guide rod 81 slides on the lifting plate 3 and compresses the spring 83, and then the electric grinding disc 5 passes through the ring mouth of the pressure ring plate 82 and enters the inner circle of the bearing for grinding, finally, during the working process, the fan 43 is started, so that negative pressure is generated inside the collection box 41, and the dust generated by grinding is sucked in through the suction pipe, and then filtered through the filter 42.
