Abstract
The utility model discloses a kind of encoder and machine tool chief axis jockey, comprise machine tool chief axis, encoder, encoder support and shaft coupling, spindle seat for machine tool is fixed on lathe one end, encoder frame bottom two ends are fixed on spindle drum one end, encoder is fixed on the encoder support other end, encoder power shaft puts in encoder support, and flexible clutch two ends are fixedly connected with machine tool chief axis termination, encoder power shaft respectively by the mode be fixedly connected with that expands.The utility model structure is simple, easy to use, the flexible clutch that encoder power shaft adopts oil resistant rubber to make with machine tool chief axis is connected, overcome the defect that the jockey encoder power shaft that causes easily damages or fractures due to machine tool chief axis side knock vibration, extend the service life of encoder, ensure lathe stable operation.
Description
Technical field
The utility model relates to a kind of jockey of lathe output, is especially a kind ofly arranged on the encoder of principal axis of pressing machine or Digit Control Machine Tool termination and the jockey of main shaft, belongs to metal forming machinery technical field.
Background technology
Encoder is a kind of high precision test instrument for detected pressures machine, Digit Control Machine Tool movement velocity, position, and the jockey of principal axis of pressing machine or main shaft of numerical control machine tool and encoder directly affects serviceability and the security performance of forcing press or Digit Control Machine Tool.The connection of existing principal axis of pressing machine or main shaft of numerical control machine tool and encoder main shaft adopts universal joint or metal axle sleeve to connect, the rigidity of encoder support is poor, when particularly forcing press carries out stamping press, principal axis of pressing machine is subject to lateral impact loading and creates more greatly larger vibration, larger owing to installing rear encoder main shaft and principal axis of pressing machine or main shaft of numerical control machine tool connection coaxiality deviation, under the effect of principal axis of pressing machine side knock vibration, easy damage even fractures encoder main shaft, affects the normal work of forcing press.
Utility model content
the purpose of this utility model is to provide and a kind ofly provides encoder power shaft and the machine tool chief axis jockey that structure is simple, easy for installation, can avoid damaging encoder power shaft.
The utility model is achieved by the following technical programs:
A kind of encoder and machine tool chief axis jockey, comprise machine tool chief axis, encoder, encoder support and shaft coupling, described machine tool chief axis one end is by bearings in spindle seat for machine tool, and described spindle seat for machine tool is fixed on lathe one end; Described encoder support is several fonts of evagination, encoder frame bottom two ends are fixed on spindle drum one end, encoder is fixed on the encoder support other end, the encoder power shaft relative with machine tool chief axis end face puts in encoder support, and flexible clutch two ends are fixedly connected with machine tool chief axis termination, encoder power shaft respectively by the mode be fixedly connected with that expands.
The purpose of this utility model can also be realized further by following technical measures.
Aforesaid encoder and machine tool chief axis jockey, wherein said flexible clutch adopts oil resistant rubber to make, and the hardness of described oil resistant rubber is greater than shore hardness 80.
The utility model structure is simple, easy to use, and encoder is fixed on lathe one end by the encoder support that rigidity is larger, and fixing-stable is reliable.The flexible clutch that encoder power shaft adopts oil resistant rubber to make with machine tool chief axis is connected, overcome under the effect of machine tool chief axis side knock vibration, the defect that existing jockey causes encoder power shaft easily to damage or fracture, extend the service life of encoder, ensure lathe stable operation.
Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises machine tool chief axis 1, encoder 2, encoder support 3 and shaft coupling 4, machine tool chief axis 1 right-hand member end is supported in spindle seat for machine tool 6 by bearing 5, spindle seat for machine tool 6 left end is positioned in installing hole 7, and the flange circle 61 that its right-hand member radial direction extends is fixed on lathe right-hand member by 4 screws.
Become two ends bottom the encoder support 3 of a few font evagination to be fixed on spindle drum 6 right-hand member end face by trip bolt 8 with steel plate bending, encoder 2 is fixed on encoder support 3 right-hand member, encoder support 3 rigidity is comparatively large, and encoder 2 fixed thereon is solid and reliable.The encoder power shaft 21 of encoder 2 left end is relative with machine tool chief axis 1 right-hand member end face, encoder power shaft 21 puts in encoder support 3 left, and flexible clutch 4 two ends are fixedly connected with machine tool chief axis 1 right-hand member termination, encoder power shaft 21 respectively by the mode be fixedly connected with that expands.When lathe runs, flexible clutch 4 can reduce vibration, guarantees lathe stable operation.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
