Description

Technical Field

[0001] The invention relates to the technical field of surface treatment, in particular to a fully automatic flexible grinding device for inner and outer rings used in bearing production. Background Art

[0002] In the field of modern mechanical manufacturing, bearings are key components that require end face grinding to improve dimensional accuracy and geometric shape and reduce assembly errors. At present, the equipment for grinding the end faces of the inner and outer rings of bearings can be divided into single-end face grinding and double-end face synchronous grinding. Double-end face grinding devices have been used on a large scale in mechanical factories due to efficiency and other reasons.

[0003] However, the existing double-end surface grinding devices for inner and outer rings of bearings still have the following technical problems in actual operation: for example, traditional clamping devices mostly use rigid gear jigs, and the jigs need to be frequently replaced for bearings of different diameter specifications. This is not only time-consuming and labor-intensive, but also mechanical clamping is prone to surface damage, making it difficult to meet the processing requirements of high-precision bearings. In addition, in order to effectively recycle debris and used grinding fluid, existing equipment usually has a filter component, but the traditional filter component lacks an effective separation mechanism. After the debris generated during the grinding process mixes with the grinding fluid, the grinding fluid easily adheres to the debris and is difficult to completely separate from the debris. When the debris is subsequently collected, the grinding fluid retained on the filter component and the debris is prone to dripping and polluting the environment. Summary of the Invention

The first drive device drives the gear fixture to rotate through the linkage disc, causing the bearing to form a planetary motion under the action of the inner and outer ring gears, while the second grinding disc maintains constant pressure contact with the upper surface of the bearing through the lifting mechanism. This structure enables double-sided processing in a single clamping and avoids secondary clamping errors.

By controlling the magnetic field switching of the first electromagnet and the third electromagnet, the first drive device can control the rotation of the first rotating seat or the second rotating seat according to the working process, that is, during the grinding of the inner and outer rings of the bearing, the first rotating seat and the linkage disk are fixed together by the first electromagnet, and the first rotating seat is controlled to rotate by the first drive device to enable the first grinding mechanism to work normally. When the grinding of the inner and outer rings of the bearing is completed, the second rotating seat and the linkage disk are fixed together by the third electromagnet, and the second rotating seat and the filter assembly are controlled to rotate by the first drive device, and the centrifugal force is used to remove the grinding fluid remaining on the debris inside the filter assembly, thereby avoiding the grinding fluid dripping into the external environment when the debris is collected, preventing the debris from sticking, and facilitating subsequent cleaning.

A group of air bags 233 are arranged at one end of each group of push rods 236 close to the axis of the annular seat 231. A first liquid storage tank 235 is arranged at the end of the annular seat 231 away from the axis. An adjustment frame 232 is arranged in the first liquid storage tank 235.

A filter screen 612 is provided in the guide groove 611, and a drainage hole 613 is provided below the guide groove 611. The annular slider 63 is arranged on the outside of the waste box 6 and is connected to the second rotating seat 52. The annular slider 63 is connected to the filter frame 61 through a connecting rod 62. During the grinding of the inner and outer rings of the bearing, the used grinding fluid will fall into the waste box 6 and pass through the filter screen 612. It will flow along the guide groove 611 and the drainage hole 613 to the grinding fluid recovery system and intercept debris through the filter screen 612. When the grinding of the inner and outer rings of the bearing is completed, the first driving device drives the second rotating seat 52 to rotate, and the filter frame 61 will rotate at high speed in the waste box 6. Under the action of centrifugal force, the grinding fluid retained in the debris and the filter frame 61 will be thrown away to facilitate subsequent collection of the debris.

[0042] like Figure 8 As shown, the waste box 6 includes an upper box body and a lower box body. The upper box body is fixedly installed below the fixed plate 21, and the lower box body is detachably installed below the upper box body by bolts. The connecting rod 62 is snap-connected with the filter frame 61. Through the above technical solution, the present invention can quickly remove the filter frame 61 from the waste box 6 by disassembling the lower box body, so as to facilitate subsequent cleaning of the filter frame 61.

[0043] The working principle of the present invention is as follows: before work, the inner ring or outer ring of the bearing is placed inside the several groups of annular seats 231, and then the lifting mechanism is turned on, and the second grinding mechanism 3 is driven to descend by the lifting mechanism until the second grinding disk 311 contacts the upper end surface of the inner and outer rings of the bearing. Then the staff turns on the second electromagnet 312. At this time, under the action of the hydraulic pressure, the first positioning frame 317 and the second positioning frame 318 will extend out of the first annular groove 315 and the second annular groove 316 and apply pressure to the adjusting frames 232 on the several groups of annular seats 231, so that the several groups of adjusting frames 232 move downward, and the hydraulic oil in the first liquid storage tank 235 is squeezed into the several groups of telescopic grooves 234 through the adjusting frames 232, so that the inner ring or outer ring of the bearing is fixed by the several groups of push rods 236 set in each group of annular seats 231. Finally, the staff can turn on the first electromagnet 241 to fix the first rotating seat 24 and the linkage disk 53 together, and drive the mounting disk 31 and the second grinding disk 53 through the second driving device. The cutting disc 311 rotates, and the first rotating seat 24 is driven to rotate by the first driving device. At this time, several gear jigs 23 will carry the inner and outer rings of the bearing to rotate between the first grinding disc 22 and the second grinding disc 311, and the upper and lower end surfaces of the inner and outer rings of the bearing are ground by the first grinding disc 22 and the second grinding disc 311. In the process of grinding the inner and outer rings of the bearing, the grinding liquid delivery system continuously delivers grinding liquid into the conduit 33, collects the used grinding liquid through the waste box 6, intercepts the debris in the used grinding liquid through the filter assembly, and recovers the purified grinding liquid through the grinding liquid recovery system. When the grinding of the inner and outer rings of the bearing is completed, the third electromagnet 521 is turned on to fix the second rotating seat 52 and the linkage disc 53 together, and the second rotating seat 52 and the filter assembly are controlled to rotate by the first driving device to remove the grinding liquid remaining on the debris inside the filter assembly, so as to avoid the grinding liquid on the debris from dripping into the external environment when the debris is collected later, and at the same time prevent the debris from sticking together and being difficult to clean.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
