Summary of the invention
In order to overcome the defect existing in prior art, the bevel-gear spherical clamp that the utility model object is to provide a kind of accurate positioning, can processes many parts simultaneously, working (machining) efficiency is high, qualification rate is high.
To achieve these goals, the utility model is by the following technical solutions:
The utility model provides a kind of bevel-gear spherical clamp, comprise crossed body axle, be connected to left end gland and the right-hand member gland at two ends, crossed body axle left and right, left end gland and right-hand member gland are fixed by being sleeved on hexagon nut with flange A and the hexagon nut with flange B at two ends, crossed body axle left and right.
Two ends, described crossed body axle left and right are provided with in centre bore, centre bore and are provided with screw thread, and described crossed body axle stage casing is cube structure.
The size of described cube structure depends on the size with grinding spherical diameter, cube structure is upper and lower, the dimensional tolerance L≤0.02mm of 4 the face opposite end centre bores in front and back, form and position tolerance D1≤the 0.01mm of flatness, perpendicularity, symmetry/position degree, cube structure is upper and lower, respectively there is 1 bearing pin at 4 Ge Mian centers, front and back, bearing pin perpendicularity obverse with it and position degree D2≤0.01mm.
Described crossed body axle left end head has the flat small stair of milling, fixing hoop during for grinding.
In described left end gland and right-hand member gland, be provided with internal taper hole, the tapering of internal taper hole is identical with the tapering of part.
On described left end gland and right-hand member gland, be provided with lightening core.
Described crossed body axle is threaded fixing with hexagon nut with flange A and the hexagon nut with flange B employing at two ends, left and right.
Compared with prior art, the utlity model has following advantage:
1, during clamping parts, with inner bore of part and small end face location, synchronize with detected parameters, can effectively guarantee the uniformity of sphere size, improve crudy, its qualification rate is high.
2, simultaneously clamping, process many parts, easy to loading and unloading, working (machining) efficiency is high.
3. this fixture is highly suitable for the gear of machining of bevel gears spherical grinding class, also can process other type gears.
Accompanying drawing explanation
Fig. 1 is existing clamp structure schematic diagram in background technology;
Fig. 2 is the utility model structural representation;
Fig. 3 is this crossed body mandrel structure schematic diagram;
In figure: tapering check axle 11, part 12, lathe are top 13, crossed body axle 1, hexagon nut with flange B2, right-hand member gland 3, left end gland 4, hexagon nut with flange A5, workpiece 61, workpiece 62, workpiece 63, lathe top 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
As Figure 2-3: the utility model provides a kind of bevel-gear spherical clamp, comprise crossed body axle 1, be connected to left end gland 4 and the right-hand member gland 3 at crossed body axle 1 two ends, left and right, left end gland 4 and right-hand member gland 3 are fixed by being sleeved on hexagon nut with flange A5 and the hexagon nut with flange B2 at crossed body axle 1 two ends, left and right.
Described crossed body axle 1 two ends, left and right are provided with in centre bore, centre bore and are provided with screw thread, and described crossed body axle 1 stage casing is cube structure.
The size of described cube structure depends on the size with grinding spherical diameter, cube structure is upper and lower, the dimensional tolerance L≤0.02mm of 4 the face opposite end centre bores in front and back, form and position tolerance D1≤the 0.01mm of flatness, perpendicularity, symmetry/position degree, cube structure is upper and lower, respectively there is 1 bearing pin at 4 Ge Mian centers, front and back, bearing pin perpendicularity obverse with it and position degree D2≤0.01mm.
Described crossed body axle 1 left end head has the flat small stair of milling, fixing hoop during for grinding.
In described left end gland 4 and right-hand member gland 3, be provided with internal taper hole, the tapering of internal taper hole is identical with the tapering of part.
On described left end gland 4 and right-hand member gland 3, be provided with lightening core.
Described crossed body axle 1 is threaded fixing with hexagon nut with flange A5 and the hexagon nut with flange B2 employing at two ends, left and right.
During use, the hexagon nut with flange A5 at fixture two ends and hexagon nut with flange B2 are unclamped to two ends respectively, make left end gland 4 and right-hand member gland 3 to two ends, be offset respectively 10mm, then workpiece 61,62,63,64(is not shown) be respectively charged into that square in crossed body axle 1 is upper and lower, on the bearing pin in the middle of the face of 4 of front and back, once pack 4 parts into, tighten respectively hexagon nut with flange A5 and the hexagon nut with flange B2 at two ends, make left end gland 4 and right-hand member gland 3 compressing components.With lathe top 7, holding out against crossed body axle 1 two ends centre bore can process, after process finishing, and loose ends hexagon nut with flange A5 and hexagon nut with flange B2, skew left end gland 4 and right-hand member gland 3 just can be dismantled part.
