Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment

[0025] Please refer to Figures 1 to 5 , which is an embodiment of the present invention. This embodiment provides a technical solution: a pressure rotor positioning device for a bearing grinding machine, including

[0026] Two positioning rollers 12 respectively located above and below the bearing 4 to be processed, and the positioning rollers 12 are rotatably installed on one side of the pallet 11 through a rotating shaft. The pallet 11 is fixed on the grinding machine frame, and the upper and lower positioning rollers 12 can position the bearing 4 to be processed;

[0027] And a front idler roller 22 located on the right side of the bearing 4 to be processed, and the front idler roller 22 is rotatably installed on the front baffle 21 through a rotating shaft. The front baffle 21 is fixed on the grinding machine frame, and the front idler roller 22 can position one side of the bearing 4 to be processed;

[0028] And a rear substrate 31 fixed on the grinding machine frame and located on the left side of the bearing 4 to be processed, a movable shaft 32 movably penetrating the surface of the rear substrate 31, a pressure base plate 33 mounted on the right end surface of the movable shaft 32, and a contact plate 34 mounted on the right side surface of the pressure base plate 33 and in extrusion contact with the bearing 4 to be processed. A regulating ring 36 and a first spring 35 are also sleeved on the surface of the movable shaft 32 relative to the right side of the rear substrate 31, and the first spring 35 is located between the regulating ring 36 and the pressure base plate 33. Under the pushing of the first spring 35, it can ensure that the contact plate 34 and the bearing 4 to be processed always maintain a good degree of fit during the grinding process of the grinding machine, ensure the positioning effect of the bearing 4 to be processed, and at the same time, the position of the regulating ring 36 is adjustable, which is convenient for adjusting the tightening force of the first spring 35 later.

[0029] In this embodiment, preferably, an end block 38 is fixed to the left end of the movable shaft 32 relative to the left side of the rear substrate 31, so that the movable shaft 32 will not fall off and separate from the rear substrate 31.

[0030] In this embodiment, preferably, two adjusting screws 37 are rotatably mounted on the left side surface of the regulating ring 36, and the left ends of the two adjusting screws 37 penetrate to the left side of the rear substrate 31 and are threadedly connected to the rear substrate 31. Subsequently, the operator can rotate the adjusting screws 37 to adjust the position of the regulating ring 36. When the position of the regulating ring 36 changes, the extrusion force of the regulating ring 36 on the first spring 35 changes, which also makes the pushing force of the first spring 35 on the pressure base plate 33 and the contact plate 34 change, thereby adjusting the extrusion force of the contact plate 34 on the bearing 4 to be processed and achieving the effect of adjustable tightening force. Two threaded holes 311 for the adjusting screws 37 to penetrate are formed through the surface of the rear substrate 31, so that the adjusting screws 37 can be smoothly rotated and screwed on the surface of the rear substrate 31.

[0031] In this embodiment, preferably, a hexagonal groove 371 is formed on the left end surface of the adjusting screw 37, which is convenient for the subsequent operator to rotate and screw the adjusting screw 37 with an internal hexagonal bolt.

[0032] In this embodiment, preferably, two connecting insertion rods 341 are symmetrically welded and fixed to the left side surface of the contact disk 34, and two connecting insertion holes 331 for the connecting insertion rods 341 to insert are formed on the surface of the pressure base disk 33 for the preliminary connection between the contact disk 34 and the pressure base disk 33. A disassembly and assembly structure 39 is further provided between the pressure base disk 33 and the contact disk 34 for the subsequent separate disassembly, replacement of the contact disk 34. The disassembly and assembly structure 39 includes a movable notch 391 penetratingly formed on the surface of the pressure base disk 33, and two movable base strips 392 movably arranged inside the movable notch 391. A limiting clamping rod 394 is welded and fixed to one side surface of the movable base strip 392. A limiting clamping hole 395 corresponding to the limiting clamping rod 394 is penetratingly formed on the surface of the connecting insertion rod 341. The end of the limiting clamping rod 394 penetrates into the limiting clamping hole 395, which can realize the stable limitation of the connecting insertion rod 341 and the contact disk 34, ensure the installation stability of the contact disk 34. A second spring 393 is further installed inside the movable notch 391 between the two movable base strips 392. Under the pushing of the second spring 393, the end of the limiting clamping rod 394 can be stably clamped in the limiting clamping hole 395 during daily use, ensuring the limiting stability of the connecting insertion rod 341. The two ends of the movable base strip 392 respectively extend to the two ends of the movable notch 391. When an operator needs to remove and replace the contact disk 34 later, only need to use a finger to move the movable base strip 392 towards the center of the movable notch 391, so that the second spring 393 is gradually compressed until the end of the limiting clamping rod 394 moves out of the limiting clamping hole 395, then the limitation of the connecting insertion rod 341 is released. At this time, the contact disk 34 can be laterally moved to complete the separate disassembly of the contact disk 34, which is convenient for the separate disassembly and replacement of the contact disk 34, without replacing the pressure base disk 33 together, that is, it reduces the maintenance cost and simplifies the subsequent maintenance steps.

[0033] In this embodiment, preferably, a guide rod 396 is fixed inside the movable notch 391, and the movable base strip 392 and the second spring 393 are both slidably sleeved on the guide rod 396, so that the movable base strip 392 can be guided and supported by the guide rod 396 when sliding inside the movable notch 391, and at the same time, the second spring 393 will not fall off from the guide rod 396.

[0034] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
