Abstract
The invention belongs to the field of tool design and particularly relates to a closing tool used for bearing mounting and fixation. Existing tools used for closing joint bearings have defects in structure and shape; six punch points of each closing tool are fine and thin in structure and easy to wear; in the previous punch-closing process, the punch points are not clear, and closing is not conducted closely, and consequently bearings fall out easily; and the manually-operated closing manner in which punches arematched with hammers is adopted for closing parts, and due to reasons, part closing quality cannot be guaranteed, and part closing efficiency is not high. The closing tool is low in labor intensity, high in work efficiency, easy to operate, reliable in positioning and capable of achieving automatic part machining.
Description
Technical field
The invention belongs to Fixture Design field, be specifically related to a kind of closing in instrument installed for bearing and fix.
Background technology
Fig. 1 and Fig. 2 is at present for the frock that joint bearing closes up, Shortcomings part in structure and profile.The structure at 6 punching point places of closing in instrument is thin and thin, easily weares and teares.When previous punching pin closes up, punching loses count of, and closes up not tight, easily causes coming off of bearing.And be utilize punching pin to the closing in of part, coordinate the manual closing in mode of hammer.The quality causing part to close up in these reasons can not be guaranteed, the efficiency that part closes up is not high yet.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of labour intensity is little, operating efficiency is high, simple to operate, location is reliable, can realize the one closing in instrument automatically processed part.
Technical scheme of the present invention is: a kind of closing in instrument, and for the installation of bearing with fixing, this closing in instrument is made up of pressure head body and die holder; Described pressure head body is cylindrical structure, and have location guide shaft, the face, outer ring of taper and inner ring face in its end, face, outer ring and inner ring face intersection circumferentially have multiple pressure head and rush a little, and pressure head body and location guide shaft are to be tightly fixed; Described die holder has shoulder hole in its one end, and the other end is closed, and on hole wall, have the axially extended draw-in groove from openend.
Face, described outer ring and the face of cylinder have the gradient being not more than 15 °, and face, outer ring and inner ring face form the angle being not more than 60 °.
Described pressure head punching point forms the semi-circular structure being not less than R1.5 vertically, and the size of R is with the size variation of institute's machining bearing.
The number of described pressure head punching point is determined according to the size of institute's machining bearing.
The dot thickness that rushes of described pressure head punching point is not less than 0.1mm, and pressure head rushes the size variation of thickness with institute's machining bearing of point.
Described pressure head punching point is connected with face, outer ring.
The diameter of described location guide shaft is with the size variation of institute's machining bearing.
The invention has the beneficial effects as follows: a kind of closing in instrument of the present invention coordinates die holder by pressure head body, utilizes forcing press to realize part automatic necking.In profile, closing in mode and closing in intensity, be obtained for obvious raising with closing in instrument before, punching point is even and deep, substantially increases crudy and efficiency, alleviates the labour intensity of operator.

Detailed description of the invention
Below the present invention is described in further details.
Please refer to Fig. 3-5, a kind of closing in instrument, for the installation of bearing with fixing, this closing in instrument is made up of pressure head body 1 and die holder 2; Described pressure head body 1 is cylindrical structure, has location guide shaft 3, the face, outer ring 4 of taper and inner ring face 6 in its end, and face, outer ring 4 and inner ring face 6 intersection circumferentially have multiple pressure head punching point 5, and pressure head body 1 and location guide shaft 3 are to be tightly fixed; Described die holder 2 has shoulder hole in its one end, and the other end is closed, and on hole wall, have the axially extended draw-in groove from openend.
Face, described outer ring 4 and the face of cylinder have the gradient being not more than 15 °, and face, outer ring 4 and inner ring face 6 form the angle being not more than 60 °.
Described pressure head punching point 5 forms the semi-circular structure being not less than R1.5 vertically, and the size of R is with the size variation of institute's machining bearing.
The number of described pressure head punching point 5 is determined according to the size of institute's machining bearing.
The dot thickness that rushes of described pressure head punching point 5 is not less than 0.1mm, and pressure head rushes the size variation of thickness with institute's machining bearing of point 5.
Described pressure head punching point 5 is connected with face, outer ring 4.
The diameter of described location guide shaft 3 is with the size variation of institute's machining bearing.
Operation principle of the present invention is: when joint bearing part closes up, be first positioned in die holder 2 by bearing parts, then put pressure head body 1; After whole instrument and part place, be placed on the workbench of forcing press; Arrange the stroke of forcing press, opening pressure machine, processes part.The manual crimping processing method utilizing the present invention more traditional is compared production efficiency and is significantly improved, and solves joint bearing part closing in punching and loses count of, and close up not tight problem, utilizes and present invention achieves the automatic necking utilizing forcing press to part; Process with closing in before, have waited until obvious reinforcement in the intensity of tool profile and service life, closing in mode and closing in intensity are obtained for obvious raising, punching point is even and deep, substantially increase crudy and efficiency, alleviate the labour intensity of operator.
