[0003] The honing tool is divided into two forms: single and multi-strip according to the number of honing sticks inlaid. The multiple honing sticks of the multi-strip honing tool are equally distributed on the honing head, and can always be concentric with the honing rod when expanding; but the single When the honing tool expands, it can only maintain concentricity with the honing rod at one diameter position. Therefore, when selecting a single honing tool for honing, it is necessary to use a honing tool with an optional aperture, which has strong specialization, narrow application range, and high cost.
[0004] In addition, in actual processing, the honing tool is often due to factors such as the allowance of the workpiece aperture, the size of the grinding force, and the wear of the honing rod head, which will cause the axis of the honing head to deviate from the rotation center, affecting the shape and position tolerance of the aperture and surface roughness. The degree of honing, especially the honing of small holes, will break the honing rod or honing stick
[0005] In the prior art, after the honing tool is clamped on the main shaft of the honing machine, in order to adjust the axis of the honing head, a plurality of adjusting screws are arranged on the side of the main shaft chuck of the honing machine, and the honing is adjusted by tightening or loosening each adjusting screw. The axis of the head, the adjustment is cumbersome, and the adjustment operation has high technical requirements for workers

Embodiment Construction
[0029] Such as Figure 1~9 As shown, a chuck with adjustable axial displacement of a honing tool includes a chuck main shaft 1-1, a chuck jacket 1-2, an upper adjusting nut 2-1, a lower adjusting nut 2-2, a displacement eccentric body 3, an upper The inclined pusher 4-1 and the lower inclined pusher 4-2, the lower end of the chuck main shaft 1-1 is connected with the upper end of the chuck outer 1-2, and the upper adjustment nut 2-1 and the lower adjustment nut 2-2 are respectively arranged on The upper end and the lower end of the chuck jacket 1-2 are threadedly matched with the chuck jacket 1-2, and the displacement eccentric body 3, the upward inclined push piece 4-1, and the downward slope push piece 4-2 are arranged in the chuck jacket 1-2 , the upward inclined push piece 4-1 and the downward inclined push piece 4-2 are arranged on the left and right sides of the displacement eccentric body 3, the contact surface between the upward inclined push piece 4-1 and the displace...

The invention relates to an axis displacement adjustable chuck of a honing tool. The chuck comprises a chuck main shaft, a chuck outer sleeve, an upper adjusting nut, a lower adjusting nut, a displacement eccentric body, an upper inclined pushing piece and a lower inclined pushing piece; and the displacement eccentric body, the upper inclined pushing piece and the lower inclined pushing piece arearranged in the chuck outer sleeve, and the upper inclined pushing piece and the lower inclined pushing piece are arranged on the left side and the right side of the displacement eccentric body. Whenthe upper inclined pushing piece and the lower inclined pushing piece ascend and descend in the same direction in the axial direction, the displacement eccentric body is pushed by an inclined face tohorizontally move left and right, the upper adjusting nut drives the upper inclined pushing piece to ascend and descend in the axial direction through forward and reverse rotation, and the lower adjusting nut drives the lower inclined pushing piece to ascend and descend in the axial direction through forward and reverse rotation. The chuck has the beneficial effects that the whole adjustable chuckis small in size and compact in structure. Through the axis position adjusting function of the adjustable chuck, the honing hole diameter range of the honing tool can be correspondingly enlarged, thespecification types and the storage amount of tools of the same series are greatly reduced, the use cost is reduced, the utilization rate of the tools is increased, the service life of the tools is prolonged, and the honing precision is improved.
Description
technical field [0001] The invention relates to the technical field of clamping mechanisms for honing tools, in particular to a chuck with adjustable axis displacement for honing tools. Background technique [0002] Honing process is to use one or more honing sticks inlaid on the circumference of the honing tool. Under the action of the mechanism in the main shaft of the honing machine, it expands radially and presses it against the hole wall of the workpiece. Through the rotation and reciprocating motion of the main shaft, it realizes Honing processing. [0003] The honing tool is divided into two forms: single and multi-strip according to the number of honing sticks inlaid. The multiple honing sticks of the multi-strip honing tool are equally distributed on the honing head, and can always be concentric with the honing rod when expanding; but the single The honing tool can only maintain concentricity with the honing rod at one diameter position when it expands. Therefore, ...
