Specific embodiment
The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiments without making creative work, belong to the utility model
Protection scope.
Embodiment one
A kind of magnetic core cylindrical grinder including rack, two cylindricalo grinding grinding wheels being installed in rack, is set to rack front
The V-type rail of midline position between two cylindricalo grinding grinding wheels of face is arranged in several round magnetic cores of cylinder along V-type rail
To grinding area push between two cylindricalo grinding grinding wheels to be ground.In addition, further including magnetic core outer circle grinding jig, for pressing from both sides
Hold several round magnetic cores for being arranged in cylinder, to avoid magnetic core in the honed journey of outer circle sideslip, guarantee grinding quality.
As shown in Figure 1, the magnetic core outer circle grinding jig 1 includes chuck body 11, the chuck body 11 includes setting side by side
The first clamp arm 111 and the second clamp arm 112 are set, is fixed with fixed mandril 12 on the inside of first clamp arm, described second
Be connected with movable mandril 13 on the inside of clamp arm, formed between the fixed mandril 12 and movable mandril 13 nip arrangement at
The clamping length space of several round magnetic cores of cylinder, the activity mandril 13 are connected with resiliency urged activity mandril 13 to fixation
The mobile spring 14 in 12 direction of mandril.
Therefore, movable mandril 13 cooperates resilient clamp to be arranged in cylinder under 14 thrust of spring with fixed mandril 12
Several circle magnetic cores, several circle magnetic cores axial restraints as a whole, in grinding process, single magnetic core is not easy to tilt,
It can be ground tiltedly to avoid magnetic core, improve core grinding quality.The effect of spring 14, which also resides in, will not be such that single magnetic core clamps completely
It is not able to rotate, to make magnetic core that can rotate in grinding process, completes the grinding of entire outer circle.
Wherein, the bottom of second clamp arm 112 be equipped with spring positioning slot 1121, the two of the spring positioning slot 1121
Side is respectively equipped with the first side wall and second sidewall, and the first side wall is equipped with movable span, and the activity mandril 13 is worn equipped with activity
The active segment of movable span is crossed, the active segment is circumferentially equipped with the flange abutted with the first end of spring on the inside of the first side wall
131, the activity mandril 13 is additionally provided with the spring positioning section connecting with flange, and the second sidewall is equipped with the spring positioning of protrusion
Column 1222, the first end of the spring are coated at spring positioning section, and the second end of the spring is coated at spring retention posts 1222
And it is abutted with second sidewall.Thus, above-mentioned technical proposal enables spring to position and play a role.
In addition, the bottom inside of first clamp arm is equipped with notch 1111, the fixed mandril 12 is fixed on indentation, there,
So as to increase the length in clamping length space.
In order to which after the completion of grinding, magnetic core is unclamped in movable 13 activity of mandril, alternatively, second clamp arm 112
It is hinged with control-rod 15, the first end of the control-rod 15 is connect with movable mandril 13, and control-rod 15 is rotated around hinged support
With 13 compressed spring 14 of driving activity mandril, to unclamp the clamping to several round magnetic cores.Meanwhile second clamp arm
112 offer and pass through and provide the through slot of rotation space for control-rod, and hinged screw 151 is threadedly connected to the second clamp arm 112,
Hinged support as control-rod 15.
It is not very big since spring 14 passes through the clamping force that movable mandril 13 acts on magnetic core, while magnetic core had been ground
By the active force of grinding wheel in journey, therefore it is easy bounce upwards.In order to solve this problem, first clamp arm 111 and
The excircle orientation axis 115 for positioning several round magnetic core outer circles is connected between two clamp arms 112.The excircle orientation axis
Shaft end is connect with adjusting block 114, and it is interior that the adjusting block 114 uses adjusting screw to be fixed on the first clamp arm/second clamp arm
The shaft end for stating excircle orientation axis is first connect by side with adjusting block 114, then adjusting block 115 is fixed on the first clamp arm/second folder
Tight arm, to facilitate the installation of excircle orientation axis.Further, the adjusting block is equipped with waist type groove, and adjusting screw passes through
Waist type groove adjusts 114 fixed height of adjusting block by waist type groove, so that the height of excircle orientation axis 115 is adjusted, to be suitable for not
With the magnetic core of diameter.
Embodiment two
On the basis of example 1, guiding trestle 2 shown in Fig. 2 is increased, magnetic core locating guide device is constituted.It is described
Guiding trestle 2 includes the guide pad 21 that suspension is installed on above chuck body, and the 21 guide clamp ontology of guide pad is in magnetic core
It is moved axially during peripheral milling along the grinding wheel of cylindrical grinder.Chuck body moving process can be made to keep straight line in this way and erected
Directly, magnetic core is also not easy skew, further increases grinding quality.
Cooperate to form the guiding of chuck body 11 and guiding trestle 2, the chuck body 11 further includes connection first
The directive slide track 113 of clamp arm and the second clamp arm top, it is mobile that the bottom surface of the guide pad offers guidance directive slide track 113
Guide groove 211, guide groove 211 penetrate through guide pad base length both ends.
For fixed guide block 21, the guiding trestle 2 further includes L-shaped first fixed block 22 and the second fixed block 23,
