Description

Technical Field

[0001] The utility model relates to the technical field of centers, in particular to a novel mechanical rotary center. Background Art

[0002] The top is mainly used in lathes, machining centers, milling machines, grinders, boring machines, etc. It is used to support and fix accessories when these equipment are processing accessories, so as to better and more effectively process the required accessories.

[0003] There is a new type of mechanical rotary center. With the popularization of mechanical processing, many equipments need to use rotary centers. However, the traditional centers are large in size and each type of center has different characteristics, which cannot be taken into account at the same time. This new type of center has the characteristics of the traditional center, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a new type of mechanical rotary center. Utility Model Content

[0004] The main purpose of the utility model is to provide a new type of mechanical rotary center, which can effectively solve the problems in the background technology.

[0005] The utility model is implemented by the following technical scheme: a novel mechanical rotary top, comprising a top body, a top head is fixedly connected to the surface of one side of the top body, a screw is fixedly connected to the inner surface of the top body, and a sealing ring is fixedly connected to the inner surface of the top body.

[0006] Preferably, a thrust bearing is fixedly connected to the top upper surface of the mandrel, and a needle roller is fixedly connected to one side surface of the thrust bearing.

[0007] Preferably, a screw is fixedly connected to one side surface of the mandrel, and an outer surface of one side of the screw is connected to the inner surface of the mandrel body.

[0008] Beneficial Effects

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] By assembling the top body and the top head into a whole, the top body is composed of the top head, screw, bolt, thrust bearing, needle roller and sealing ring. By installing needle rollers instead of traditional bearings, the overall outer circle of the top is effectively reduced, and the rotation speed and higher load-bearing weight are effectively increased. The top body of this new top is made into a cavity for the needle roller to rotate and bear the outer ring, and the top head of the top is made into a cavity for the needle roller to rotate and bear the inner ring, which further improves the precision.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-2 As shown, a new type of mechanical rotary top includes a top body 1, a top head 2 is fixedly connected to the surface of one side of the top body 1, a screw 3 is fixedly connected to the inner surface of the top body 1, and a sealing ring 4 is fixedly connected to the inner surface of the top body 1.

[0016] A thrust bearing 6 is fixedly connected to the top upper surface of the plug 2 , and a needle roller 5 is fixedly connected to one side surface of the thrust bearing 6 .

[0017] A screw 7 is fixedly connected to one side surface of the plug 2 , and an outer surface of one side of the screw 7 is connected to the inner surface of the top body 1 .

[0018] The overall hardness of the top body 1 is 58 RHC degrees.

[0019] Working principle and process of this utility model:

[0020] The staff assembled the top body 1 and the top head 2 into a whole. The top body 1 is composed of the top head 2, the screw 3, the screw 7, the thrust bearing 6, the needle roller 5, and the sealing ring 4. By installing the needle roller 5 instead of the traditional bearing, the overall outer circle of the top is effectively reduced, and the rotation speed and the load-bearing weight are effectively increased. The top body 1 of this new top is made into a cavity for the needle roller 5 to rotate and bear the outer ring, and the top head 2 of the top is made into a cavity for the needle roller 5 to rotate and bear the inner ring, which further improves the precision.
