The utility model provides a technical scheme that above-mentioned problem adopted is: a slender shaft inserted internal spline fixture comprises a base, wherein the bottom of the base is connected with a lower positioning seat, the top of the base is connected with a positioning seat, the top of the positioning seat is connected with a support body, an expansion sleeve is arranged in the support body, and a locking sleeve is sleeved outside the expansion sleeve; the expansion sleeve comprises a pressing conical surface, a clamping conical surface and a guide surface, the upper end of the expansion sleeve is the pressing conical surface, the lower end of the expansion sleeve is the clamping conical surface, a step is arranged at the junction of the pressing conical surface and the clamping conical surface, and the lower end of the clamping conical surface is the guide surface; the locking sleeve is matched with the pressing conical surface and the clamping conical surface, and the locking sleeve is in threaded fit with the guide surface; the compression screw is arranged on the locking sleeve and matched with the step; a tip is arranged in the lower positioning seat; the locking sleeve is provided with a handle screw hole, and a handle is installed on the handle screw hole.
The utility model discloses a mode that the lock sleeve compressed tightly the cover that rises realizes the locking of work piece, has adopted the hold-down screw of 4M 5X20 of twisting on the lock sleeve, pushes up below the cover that rises compress tightly the conical surface and press from both sides the step in the middle of the tight conical surface, and processing is accomplished the back, and the lock sleeve counter-rotation drives the cover that rises, and the cover that rises is loosened through the step messenger on hold-down screw and the cover that rises, realizes loosening of work piece.
Compared with the prior art, the utility model, have following advantage and effect: the car new forms of energy variable speed part belongs to the very high part of precision, and the precision is high, longe-lived, the noise is low, the security is high is its essential requirement, owing to receive the restriction of equipment, the processing that conventional anchor clamps structure can't be realized, the utility model discloses slender axles insert the internal spline anchor clamps, has adopted the compound mode of sectional type, adopts the lock sleeve and the novel cooperation mode of cover that rises, and the preparation of conveniently processing has fine solution present automobile industry, new energy automobile a slender axles insert the difficult problem of internal spline.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic view of the connection structure of the locking sleeve and the expansion sleeve of the present invention.
In the figure: a base 1; a lower positioning seat 2; a positioning seat 3; a support body 4; an expansion sleeve 5; a locking sleeve 6; a pressing conical surface 7; a clamping conical surface 8; a guide surface 9; a step 10; a compression screw 11; a centre 12, a handle screw hole 13 and a handle 14.
Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
Referring to fig. 1-2, the slender shaft internal spline inserting clamp in the embodiment includes a base 1, a lower positioning seat 2 is connected to the bottom of the base 1, a positioning seat 3 is connected to the top of the base 1, a supporting body 4 is connected to the top of the positioning seat 3, an expansion sleeve 5 is arranged in the supporting body 4, and a locking sleeve 6 is sleeved outside the expansion sleeve 5; the expansion sleeve 5 comprises a pressing conical surface 7, a clamping conical surface 8 and a guide surface 9, the upper end of the expansion sleeve 5 is the pressing conical surface 7, the lower end of the expansion sleeve 5 is the clamping conical surface 8, a step 10 is arranged at the junction of the pressing conical surface 7 and the clamping conical surface 8, and the lower end of the clamping conical surface 8 is the guide surface 9; the locking sleeve 6 is matched with the pressing conical surface 7 and the clamping conical surface 8, and the locking sleeve 6 is in threaded fit with the guide surface 9; the compression screw 11 is arranged on the locking sleeve 6 and is matched with the step 10; a tip 12 is arranged in the lower positioning seat 2; the locking sleeve 6 is provided with a handle screw hole 13, and a handle 14 is arranged on the handle screw hole 13.
