Specific implementation mode
Illustrate the utility model below in conjunction with the accompanying drawings.
It is a kind of transmission shaft fixed clamping device as shown in Figs. 1-5,1 left side of bottom plate is equipped with baffle 11；Baffle 11 is from left-hand
The right side is equipped with tapped through hole 12；Tapped through hole 12 is equipped with the screw rod 2 being threadedly coupled；Cylindrical outer sleeve 3 is equipped with above bottom plate；
3 center of outer sleeve is machined with conical first through hole 31；First through hole 31 and tapped through hole 12 are concentric；First through hole 31 is cut
Face diameter gradually increases from left to right；3 right end outer surface of outer sleeve is machined with the first screw thread 32；Wedge shape is placed in first through hole
Block 5；5 lateral surface of wedge block is circular conical surface, coordinates with 31 inner wall of first through hole and moves, and medial surface is circular arc concave surface；Outer sleeve 3 is right
Side is equipped with sleeve 4；4 center of sleeve is equipped with screw-threaded counterbore 41；Screw-threaded counterbore 41 is threadedly coupled with the first screw thread 32；Screw thread is heavy
41 end face of hole is equipped with cylinder 42；42 center of cylinder is equipped with perforative second through-hole 43；It is logical that 42 lower end of cylinder is located at first
In hole；Support plate 6 has three pieces to be fixed on bottom plate 1, and supports outer sleeve 3.
In use, after transmission shaft 7 is passed through the second through-hole 43, it is then passed through first through hole 31, at this time turn sleeve 4,
Under the promotion of screw-threaded counterbore 41 and the first screw thread 32, cylinder 42 moves forward in first through hole 31, and end face pushes wedge shape
Block 5 moves inward, and since 31 inner wall of first through hole is taper, constantly transmission shaft 7 is given to apply pressure under 5 active force of wedge block,
Transmission shaft 7 is promoted to clamp；When needing to unclamp transmission shaft, after unclamping sleeve 4, screw rod 2 is screwed, 2 end face of screw rod pushes transmission
Axis 7 is displaced outwardly, and then transmission shaft 7 is released.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：This practicality is new
Type steps up that fixture structure is simple, and easy to operate, clamping force size can be adjusted according to the actual needs of transmission shaft, no
Transmission shaft surface is damaged, clamping stability is good, and convenient disassembly.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and be implemented, the scope of protection of the utility model can not be limited with this,
It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover in the scope of protection of the utility model
It is interior.
