As can be seen from figure 1, the bottom of the blade is an inclined plane, and a plurality of fixing holes are distributed in the middle of the blade along the central line.
Generally, a special clamp is manufactured according to the angle of a grinding surface, the clamp is poor in universality, a tiltable bench vice can be used for clamping, and when a long workpiece is ground, vibration is generated to affect machining precision due to the limitation of the width of a jaw. In order to make up for the above deficiencies, a universal fixture needs to be designed to fulfill the purpose of one fixture for multiple purposes.
Disclosure of Invention
The utility model discloses a lack a general fixture's technical problem when solving present cross shear blade grinding, provide an auxiliary device of cross shear cutting edge grinding.
The utility model discloses an adopt following technical scheme to realize: an auxiliary device for grinding the cutting edge of a cross shear comprises a base; a pair of parallel side plates is vertically arranged on the base; the side plates comprise a first side plate and a second side plate, and a plurality of first bolt holes are horizontally formed in the position, close to the vertical edge of one side, of the first side plate; second bolt holes are also formed in the positions, corresponding to the first bolt holes, of the second side plate in a one-to-one mode; the second side plate is also provided with a plurality of jacking screw holes; a rotating shaft bolt passes through the first bolt hole and the second bolt hole and is provided with a rotating shaft nut; the jacking screw hole is provided with a jacking bolt.
When the cutter is used, a blade to be processed is clamped between the first side plate and the second side plate, one fixing hole in the blade is selected to be aligned with the first bolt hole and the second bolt hole, then a rotating shaft bolt penetrates through the three holes, and the rotating shaft bolt is screwed by a rotating shaft nut. Then the position of adjustment blade (revolute the pivot bolt), make its knife face of treating the processing be the level and be higher than the curb plate top surface, then through the tight bolt in the top on the third bolt hole with the blade top tight (top tight on first curb plate), place knife sharpening device in flat grinder work platform this moment, alright carry out grinding work. A plurality of first, second bolt holes and the tight screw hole in top that set up on two curb plates can be selected according to actual need to satisfy the blade of different specifications.
The utility model discloses simple structure, it is very convenient to operate and use, can be applicable to the centre gripping of the cross shear blade of multiple specification, and then accomplishes the grinding.

Detailed Description
An auxiliary device for grinding the cutting edge of a cross shear comprises a base 6; a pair of parallel side plates is vertically arranged on the base 6; the side plates comprise a first side plate 7 and a second side plate 8, and a plurality of first bolt holes 9 are horizontally formed in the position, close to the vertical edge of one side, of the first side plate 7; second bolt holes 10 are also formed in the positions, corresponding to the first bolt holes 9, of the second side plate 8; the second side plate 8 is also provided with a plurality of jacking screw holes 11; a rotating shaft bolt 1 is arranged through the first bolt hole and the second bolt hole, and a rotating shaft nut 2 is arranged on the rotating shaft bolt 1; the jacking screw hole 11 is provided with a jacking bolt 5.
The first bolt holes 9 and the second bolt holes 10 are three and vertically arranged.
The jacking screw holes 11 are divided into three rows, each row is arranged in parallel with the first bolt holes 9, and each row of jacking screw holes 11 is provided with four jacking screw holes and the distance between every two adjacent jacking screw holes 11 is the same.
The length of the two side plates is 600 mm.
When the tool is manufactured, grooves are formed in the bottom edges of the two side plates and are welded with the bottom plate vertically, through holes, namely holes (first bolt holes and second bolt holes) of the rotating shaft, are machined in the two side plates and are perpendicular to the vertical plate, and tightly-jacking threaded holes are machined in the plate surface on the other side. The length of the cross shear blade is generally within 500mm, for this reason, the length of the clamp is selected to be about 600mm, and the width of the bottom surface of a bottom plate (the bottom plate is made of a material capable of being absorbed by magnetic force) is set to be 200mm, so as to ensure the binding force with the magnetic suction disc of the grinding machine. The both sides inboard side interval is greater than blade thickness commonly used, in order to adapt to the requirement of different grinding face angles, adopt a fixed orifices on the blade of choosing to be the pivot, grind face adjustment level, the cross shear blade leans on in one of them curb plate one side, it is tight with many bolts (puller bolt) on another curb plate face top, place the frock in flat grinder work platform, when using this anchor clamps, should clean up the magnetic force sucking disc of grinding machine, adjust the depth of parallelism of anchor clamps grinding face and emery wheel, then adsorb anchor clamps on the disk. The grinding work can be performed. If the batch size is large, the limiting device can be arranged at the lower part of the blade, and the blade does not need to be aligned again during clamping every time, so that the quality can be effectively ensured, and the efficiency can be greatly improved.
The utility model discloses simple structure, convenient to use, the practicality has gained better effect. FIG. 3 is a schematic structural view of the tool of the present application, wherein two side plates are arranged vertically and in parallel; and a jacking bolt is arranged in the jacking screw hole on the second side plate. FIG. 4 is a schematic structural view of the second side plate, on which second bolt holes and tightening screw holes are arranged; FIG. 5 is a schematic view of a first side plate structure with only first bolt holes formed therein; FIGS. 6 and 7 are schematic views showing the structure of the clamped blade, in which the bolt of the rotating shaft passes through the first and second bolt holes and the fixing hole, and the blade can rotate around the rotating shaft; the knife face of the blade to be ground is adjusted to be horizontal and higher than the top surface of the side plate; the puller bolt can jack the blade tightly.
