The utility model has the advantages of being simple in structure and convenient in operation, combine numerical control flat grinder to use and to satisfy the three face whole abrasive machining s of a clamping in with the square hole and accomplish, guarantee the size precision requirement.
Description
Technical field
The utility model belongs to Machining Technology field, relates to a kind of square opening clamp for grinding.
Background technology
Square hole Grinding Technology has sine gauge and the grinding of accurate angle bar clamping workpiece; The grinding of sinusoidal precision flatnosed pliers sinusoidal electromagnetic sucker alive clamping workpiece; The grinding of magnetic conduction v block clamping workpiece, these three kinds of Grinding Technology are applicable to the thinner workpiece of grinding thichness.At present, square opening processing adopts common plane grinding machine, and for there being multiple the square opening workpiece needing grinding, existing processing method is behind the complete face of grinding, and replacing fixture is regrinded and cut inclined-plane.This grinding processing method not easily ensures size in hole between each face and position relationship, and operation is loaded down with trivial details, and in process, non-cutting time is long.
Utility model content
The purpose of this utility model is to provide a kind of square opening clamp for grinding, solves the problem needing multiple clamping when grinding square opening, also can realize the grinding on square hole inclined-plane.
The technical solution of the utility model is: a kind of square opening clamp for grinding, is characterized in that: comprise body 1, base 2, wear-resistant sleeve 3, latch 4, housing screw 8 and gripper shoe; Body 1 upper surface symmetry fixes four pieces of gripper shoes be adjacent to the bottom surface datum level of workpiece, the side vertically fixing support plate be adjacent to side surface of workpiece datum level of body 1; The opposite side of body 1 is vertically fixed with riser, and the head arc surface of housing screw 8 is contacted by cramping face through riser and workpiece; Body 1 is arranged on base 2 top by wear-resistant sleeve 3, and body 1 respect thereto 2 rotates; Body and base correspondence position are provided with pin-and-hole, and are fixed by latch.
Beneficial effect: clamp structure of the present utility model is simple, easy to operate, the use of combining with digital control surface grinding machine can meet clamped one time and the whole grinding in the face of three in square hole be completed, and ensures dimension precision requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
For making the purpose of this utility model, content and advantage clearly, below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of square opening clamp for grinding, comprise body 1, base 2, wear-resistant sleeve 3, latch 4, gripper shoe 5, screw 6,10, lining 7, housing screw 8 and positioning key 9; Body 1 upper surface fixes four pieces of gripper shoes 5 by screw 6 symmetry, for being adjacent to the bottom surface datum level of workpiece to be machined, the side of body 1 is vertically fixed two pieces of support plates 5 by screw 6 and is adjacent to the side datum level of workpiece to be machined, make workpiece to be machined in fixture, occupy fixing position, location is reliable; The opposite side of body 1 vertically fixes two pieces of risers, during clamping workpiece, housing screw head arc surface is contacted by cramping face through riser and workpiece, completes cramping effect, tighten screw, clamping force makes the positioning reference plane of workpiece be close to the perpendicular positioning gripper shoe of fixture.Workpiece fixing is stablized, ensures can not produce displacement, skew in process.
Body 1 is arranged on base 2 top, and centre bore and wear-resistant sleeve 3 bottom of base 2 adopt interference fit, and wear-resistant sleeve 3 top adopts interference fits to connect with the centre bore of body 1; During grinding, workpiece, in clamped one time, when grinding completes the vertical plane of workpiece, is rotated to an angle together with workpiece by body 1, makes the inclined-plane in workpiece hole rotate corresponding angle relative to machine tool chief axis, the inclined-plane of grinding workpiece.Body and base correspondence position arrange two pin-and-holes, and during the vertical plane of grinding workpiece, latch inserts in " I " number pin-and-hole 13, is linked together by body with base.During grinding inclined-plane, after body rotates to an angle, latch inserts in " II " number pin-and-hole 14.The utility model makes work pieces process operation concentrate, and is easy to ensure the position dimension between machined surface and precision.Reduce trade union college number of times, thus alleviate the labour intensity of workman, boost productivity.Meanwhile, rotating grinding head, can two other face of grinding.
Base is connected with the T-slot of platen by positioning key 9, screw 10, makes the installation base surface of clamp body and platen have good contact, ensures there is fixing position relationship between fixture and lathe.
Its course of work is as follows:
The processing preparatory stage: the clamping of clamp body and workpiece; By feather key, screw, the T-slot of clamp body with digital control plain surface grinding machine workbench is connected, makes the installation base surface of clamp body and platen have fixing position relationship.The installation base surface of Workpiece fixing basal plane and clamp body is adjacent to, by hold down gag, workpiece is fixed on clamp body.
Process segment: the seating surface of workpiece and the grinding on inclined-plane.The grinding of seating surface: latch, with after clamping workpiece, inserts in corresponding pin-and-hole and tightens up by clamp body.When grinding, power is delivered on emery wheel 11 by mill bar 12 by lathe, and emery wheel does radial feed motion, and workbench drives fixture to do straight reciprocating motion together with workpiece, realizes the grinding of workpiece seating surface.The grinding on inclined-plane: after seating surface grinding, extracted by latch, is rotated counterclockwise 1 ° 42 ' by ripping bar by the first half body of clamp body, is inserted in corresponding pin-and-hole by latch and tightens up.Make workpiece minute surface rotate corresponding angle relative to machine tool chief axis, the inclined-plane of grinding will be converted into the face paralleled with machine tool chief axis, and realize the grinding of workpiece slope.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
