Abstract
The invention relates to a casing pipe fixing device. The casing pipe fixing device comprises a rotating shaft (1), wherein the rotating shaft is sleeved with the casing pipe (2); a sleeve (2a) is arranged on the side surface of the casing pipe; the casing pipe fixing device is characterized in that a group of grooves (2b) are formed in the inner side of the sleeve; each of the grooves is matched and connected with a convex piece (3); a group of screw holes (2c) are formed in the wall of the sleeve and are in one-to-one correspondence with the grooves; locking pieces (4) are matched and connected into the screw holes; the casing pipe is matched with the rotating shaft through the locking pieces and the convex pieces through locking. The casing pipe fixing device disclosed by the invention has the advantages that the device is simple in structure, convenient to manufacture, low in cost, and easy to machine; the device can tightly lock the casing pipe and the rotating shaft, and further cannot damage the surface of the rotating shaft.
Description
Technical field
The present invention relates to a kind of mechanical fastening system, particularly a kind of fixing device of sleeve pipe.
Background technique
The mechanical field of present stage is special, when sleeve pipe and rotating shaft fixing, most employing is provided with screw on sleeve pipe, then by screw, bolt or stud are directly locked with rotating shaft and are coordinated, and this mode is when working long hours, easily loosen, and when fastening screw, the surface of bolt or the easy countershaft of stud forms damage, and the surface of rotating shaft generally can be made to occur pit or scratch.Through extensively retrieval, not yet find ideal technological scheme.
Summary of the invention
The object of the invention is to solve the fixing insecure of present stage rotating shaft and sleeve pipe, easily there is the shortcomings such as damage in rotating shaft surface, and the fixing device of a kind of sleeve pipe of proposition.
To achieve these goals, present invention employs following technological scheme:
A kind of fixing device of sleeve pipe, comprise rotating shaft, slip joint casing in rotating shaft, the side of sleeve pipe is provided with sleeve, it is characterized in that: the inner side surface of described sleeve is provided with one group of groove, and be connected a jacking block in each groove, the barrel of sleeve is also provided with one group of screw, screw and groove one_to_one corresponding, to be connected locking element at screw, locked coordinate in sleeve pipe by locking element and jacking block with rotating shaft.
On the basis of technique scheme, following further technological scheme can be had:
The bottom surface of described groove is the circular arc concentric with sleeve, and wherein two symmetrical sides of described jacking block are respectively the circular arc corresponding with the bottom surface of groove and rotating shaft.
Described locking element adopts screw, bolt or stud.
When described locking element is tightened, locking element compresses jacking block, jacking block clamping shaft, and because the surface of jacking block and shaft contacts is arc structure, and surface of contact is larger, so locking is comparatively firm, and countershaft not damaged.
The invention has the advantages that: this apparatus structure is simple, easily manufactured, becomes not low and easily processes, the locking of this device to sleeve pipe and rotating shaft is firm, and countershaft surface nondestructive wound.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
