Currently, usual clamping is in shank 81 in processing for ears part, since 81 length of shank is shorter, clamping is inconvenient,
It is also easy to the phenomenon that parts fixation shift in position occur in process；Liang Ge ear 82 does not obtain clamping and positioning, processing
When the stress that is subject to it is larger, be easy to appear deformation after processing, it is difficult to guarantee geometric tolerance.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a kind of ears for being easy to guarantee geometric tolerance
Part special fixture, it is easily-deformable after solving the problems, such as current ears part clamping being inconvenient in process and processing.
The technical solution of the utility model is: it is easy to guarantee the ears part special fixture of geometric tolerance, including positioning plate,
Supporting block, pressing plate, ear's top plate and shank locating piece；Supporting block is fixed in positioning plate lower end, and lower surface is parallel to positioning plate
Upper surface；Two pressure plates, which are arranged symmetrically, is movably connected in positioning plate upper end, is used to compress one piece of ear of ears part
On the upper surface of positioning plate；Ear's top plate and shank locating piece are respectively and fixedly connected on the opposite side wall in two sides of positioning plate；It is fixed
Position plate, ear's top plate and shank locating piece three surround to form the clamping section that can accommodate ears part.
The further technical solution of the utility model is: ear's top plate is equipped with threaded hole；It further includes press bolt；Top
Pressure bolt thread is connected in the threaded hole of ear's top plate, and the end of screw rod is protruded into clamping section, is used to withstand ears
The ear of part.
Further technical solution is the utility model: pressing plate is equipped with the waist-shaped hole passed through for bolt；Two pressure plates
Positioning plate upper end is movably connected in by fastening bolt respectively.
The further technical solution of the utility model is: between being equipped between pressing plate and positioning plate for adjusting between the two
The roll adjustment component connect, roll adjustment component include being threaded in screw rod and the nut screwed with screw rod on pressing plate.
The utility model has the advantages that compared with prior art
Special fixture provided by the utility model is used for clamping ears part, is positioning base with the ear of ears part
Standard integrally can apply pressing force to ears part in the horizontal and vertical directions, and clamping is solid and reliable, effectively solve ears part
Stress concentration leads to the problem of part deformation after processing when processing, and the dimensional accuracy and geometric tolerance of ears part are easier to control
System.
The utility model is further described below in conjunction with figure and embodiment.

Specific embodiment
Embodiment 1:
As Figure 4-Figure 6, it is easy to guarantee the ears part special fixture of geometric tolerance, including positioning plate 1, supporting block 2, pressure
Plate 3, ear's top plate 4, shank locating piece 5 and press bolt 71.
Positioning plate 1 is in cuboid.Supporting block 2 is fixed in 1 lower end of positioning plate, and lower surface is parallel to the upper of positioning plate 1
Surface.Two pressure plates 3, which are arranged symmetrically, is movably connected in 1 upper end of positioning plate, is used to for one piece of ear of ears part being pressed on
On the upper surface of positioning plate 1.On the side wall opposite with the two sides that shank locating piece 5 is respectively and fixedly connected to positioning plate 1 of ear's top plate 4.
Ear's top plate 4 is equipped with threaded hole, and shank locating piece 5 is equipped with threaded hole B.Positioning plate 1, ear's top plate 4 and shank locating piece 5
