Abstract
A motorized spindle mounting structure comprises a fixed base (1), two adapter sleeves (2), adapter screws (3) and fastening screws (4). The fixed base (1) is sleeved on the outer wall of a motorized spindle (5). Two ends of the motorized spindle (5) are provided with two adapter sleeves (2) respectively. The external peripheral step of each adapter sleeve (2) is matched with an inner hole of the fixed base (1). The inner wall of each adapter sleeve (2) is matched with the outer cylindrical surface of the motorized spindle (5). The adapter sleeves (2) are axially fixed on the fixed base (1) through the fastening screws (4). The motorized spindle mounting structure has the advantages that through two-way grooves, the elasticity of the adapter sleeves is improved effectively; the adapter sleeves telescope and deform so as to self-lock and clamp the motorized spindle by the aid of the adapter screws, and positioning precision and clamping stiffness are high; stability of double-support clamping with the adapter sleeve sets at two ends is fine.
Description
Technical field
The utility model relates to a kind of electric main shaft mounting structure, a kind of high accuracy that relies on sleeve endoporus elastic shrinkage to clamp specifically, the quick electric main shaft mounting structure of high rigidity.
Background technology
The lathe equipment is subjected to the great attention of countries in the world as strategic industry all the time.In recent years lathe equipment towards high speed, height refine, intellectuality ... direction develops, and the trend of Machine Tool Main Drive high speed is to adopt " zero transmission " technology, namely adopts the electric main shaft of main shaft and motor integration.At present, electric main shaft is quite general in the application of machine industry.The electricity main shaft is as an AFU of lathe, and the user installs and uses at lathe by type selecting buying back.Provide outside cylinder and end face of flange on the general electric main shaft as the location benchmark is installed, the problem that at present common installation locate mode exists is: positioning accuracy and position stability are not high, and this may bring adverse effect to subsequent applications work.
Summary of the invention
The purpose of this utility model is to use the problem that exists in the installation at present electric main shaft, design a kind of electric main shaft mounting structure that clamps based on sleeve endoporus elastic shrinkage, thereby can realize precise and stable location and the high rigidity of electric main shaft fastening, and convenient to operation.
The technical solution of the utility model is:
A kind of electric main shaft mounting structure, it comprises fixed pedestal, sleeve, the two ends of described electric main shaft are respectively equipped with sleeve, the cylindrical seam of sleeve matches with the fixed pedestal endoporus, the endoporus of sleeve cooperates with the external cylindrical surface of electric main shaft, and sleeve is axially fixed on the fixed pedestal by trip bolt.Two sleeves have narrow groove along its axis normal direction, have another narrow groove in its cylinder seam opposite side direction that parallels to the axis, thereby can increase its elasticity, side at this groove is provided with unthreaded hole, opposite side is provided with screw, and holding screw passes unthreaded hole and packs into and fasteningly in the screw make sleeve produce distortion electric main shaft is clamped.
The beneficial effects of the utility model:
Sleeve of the present utility model effectively increases its elasticity by two-way fluting, relies on clamp screw to make it produce contraction distortion surely more electric main shaft self-locking is clamped, positioning accuracy and clamping rigidity height, reliable clamping; Two ends sleeve double base in groups clamp good stability.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2, a kind of electric main shaft mounting structure, it comprises fixed pedestal 1, two sleeves 2, holding screw 3 and trip bolt 4, described fixed pedestal 1 is sleeved on the outer wall of electric main shaft 5, the two ends of electricity main shaft 5 are respectively equipped with sleeve 2, the cylindrical seam of sleeve 2 matches with fixed pedestal 1 endoporus, and the inwall of sleeve 2 cooperates with the external cylindrical surface of electric main shaft 5, and sleeve 2 is axially fixed on the fixed pedestal 1 by trip bolt 4.Described two sleeves 2 have several narrow grooves along its axis normal direction, have corresponding narrow groove in the sleeve 2 cylinder seam opposite sides direction that parallels to the axis, side at this groove is provided with unthreaded hole, opposite side is provided with screw, and holding screw 3 passes unthreaded hole and packs into and fasteningly in the screw make sleeve 2 produce distortion electric main shaft is clamped.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
