Description

Technical Field

[0001] The utility model relates to the technical field of grinding blocks, in particular to a floating oil-sealed double-sided grinding block. Background Art

[0002] A floating oil seal is a special type of mechanical seal, which is a compact mechanical seal developed to adapt to harsh working environments. It has the advantages of strong anti-pollution ability, wear resistance, impact resistance, reliable operation, automatic compensation for end face wear, and simple structure. It is most commonly used in engineering machinery products, and is also widely used in various conveyors, sand processing equipment, and concrete equipment. When grinding the floating oil seal, a grinding block is required to press the floating oil seal on the grinding disc for grinding. The floating oil seal has a front sealing surface and a rear sealing surface. The front sealing surface is used for sealing between floating oil seals, and the rear sealing surface is used for sealing between floating oil seals and equipment. For example, the patent with publication number CN205226372U discloses a floating oil seal double-sided grinding block, including a block, the block is cylindrical, and a groove 1 for accommodating the front sealing surface of the floating oil seal is opened on the surface of one end of the block, and the groove 1 is close to the edge of the end face of the block. A groove 2 for accommodating the rear sealing surface of the floating oil seal is opened on the surface of the other end of the block, and the groove 2 is close to the edge of the end face of the block. This device enables the grinding block to process the two sealing surfaces of the floating oil seal, achieving the effect of double-sided processing, but the grinding efficiency is low and the front sealing surface and the rear sealing surface cannot be ground at the same time.

[0003] To this end, the utility model provides a floating oil seal double-sided grinding block. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a floating oil seal double-sided grinding block, comprising a shell 1, a mounting ring 5 is rotatably matched in the shell 1, a swivel 6 is rotatably matched in the mounting ring 5, grooves 7 are provided on both the front and rear sides of the swivel 6, a floating oil seal is placed in the groove 7, a plurality of first telescopic rods 8 are installed in the groove 7, a first connecting block 10 is installed on one side of the shell 1, a first grinding block 12 is installed on the first connecting block 10, a second connecting block 11 is installed on the other side of the shell 1, a second grinding block 13 is installed on the second connecting block 11, and a third grinding block 16 is fixed in the groove 7.

[0022] In this embodiment, two rotating shafts 2 are rotatably fitted inside the outer shell 1, one end of the rotating shaft 2 is fixedly connected to the mounting ring 5, and the other end of the rotating shaft 2 is provided with a threaded head 3, the threaded head 3 is located relatively outside the outer shell 1, a nut 4 is installed on the threaded head 3, and a gap is provided between the mounting ring 5 and the outer shell 1.

[0023] Specifically, when the mounting ring 5 needs to be flipped, it is only necessary to rotate the nut 4 so that the nut 4 is away from the outer shell 1, and the mounting ring 5 can be rotated through the rotating shaft 2. After the mounting ring 5 is flipped 180°, the nut 4 is turned so that the nut 4 is close to the outer shell 1, and the friction between the nut 4 and the outer shell 1 increases. The rotating shaft 2 is fixed, and the mounting ring 5 can be positioned.

[0024] The first telescopic rod 8 is fixed to one side of the groove 7 , and one end of the first telescopic rod 8 is in contact with the floating oil seal.

[0025] Specifically, one end of the floating oil seal is placed in the groove 7, and then the length of the first telescopic rod 8 is adjusted so that one end of the first telescopic rod 8 is against the floating oil seal, so that the floating oil seal can be clamped and fixed.

[0026] A second telescopic rod 9 is fixed to one side of the shell 1, one end of the second telescopic rod 9 is fixedly connected to the first connecting block 10, and a third telescopic rod 15 is fixed to the other side of the shell 1, one end of the third telescopic rod 15 is fixedly connected to the second connecting block 11, and a part of the third telescopic rod 15 is located inside the shell wall of the shell 1.

[0027] Specifically, when one end of the floating oil seal needs to be polished, the floating oil seal is clamped and fixed in the groove 7 by the first telescopic rod 8, and then the swivel 6 is rotated to drive the floating oil seal to rotate, so that the first grinding block 12 can grind one sealing surface of the floating oil seal, and the second grinding block 13 can grind the circumferential side of the other floating oil seal.

[0028] When the grinding efficiency needs to be improved, the first telescopic rod 8 can be shortened. At this time, the floating oil seal is no longer restricted. The floating oil seal is placed between the first grinding block 12 and the third grinding block 16. The floating oil seal can be rotated for grinding, and the two sealing surfaces of the floating oil seal can be ground at the same time.

[0029] A thread groove 14 is provided at the axial center of the swivel 6 , and a screw rod can be installed through the thread groove 14 . The swivel 6 can be driven to rotate by connecting the screw rod to the output end of the motor, thereby facilitating the grinding of the floating oil seal.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
