Description
Technical field
The present invention relates to frock clamp field, especially a kind of ears part special fixture for being easy to guarantee geometric tolerance.
Background technique
Ears part is the kernel component on heavy duty crane, is located between mandrel and connecting rod, for transmitting power,
It is higher to dimension precision requirement.
As shown in Figure 1-3, a kind of structure of typical ears part is as shown in Figure 1, include 81 He of shank cylindrical
It is connected to the ear 82 of two pieces of parallel arrangements on 81 1 side end face of shank.A through-hole 821 is respectively equipped in Liang Kuai ear 82,
Two through-holes 821 are facing each other, open slot 83 are equipped between Liang Kuai ear 82, the axial line of through-hole 821 is perpendicular to open slot 83
Symmetrical center line.
There are plurality of specifications for ears part, and the ears part shape of each specification is different, and size difference is larger, but all have one
A general character: through-hole 821 in Ji Liangge ear 82 is coaxial, two end faces of the axial line of through-hole 821 perpendicular to ear 82.
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.
Summary of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and provide a kind of ears part for being easy to guarantee geometric tolerance
Special fixture, it is easily-deformable after solving the problems, such as current ears part clamping being inconvenient in process and processing.
The technical scheme is that being easy to guarantee the ears part special fixture of geometric tolerance, including positioning plate, support
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 the upper of positioning plate
Surface；Two pressure plates, which are arranged symmetrically, is movably connected in positioning plate upper end, and it is fixed to be used to for one piece of ear of ears part being pressed on
On the upper surface of position 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；Positioning 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 present invention is: ear's top plate is equipped with threaded hole；It further includes press bolt；Press spiral shell
Bolt is threaded 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 part
Ear.
Further technical solution is the present invention: pressing plate is equipped with the waist-shaped hole passed through for bolt；Two pressure plates difference
Positioning plate upper end is movably connected in by fastening bolt.
The further technical solution of the present invention is: being equipped between pressing plate and positioning plate indirect between the two for adjusting
Roll adjustment component, roll adjustment component include being threaded in screw rod and the nut screwed with screw rod on pressing plate.
The invention has the following advantages over the prior art:
Special fixture provided by the invention can be in water using the ear of ears part as positioning datum for clamping ears part
Pressing force is integrally applied to ears part on gentle vertical direction, clamping is solid and reliable, effectively solves to answer when the processing of ears part
Power concentration leads to the problem of part deformation after processing, and the dimensional accuracy and geometric tolerance of ears part are more easily controlled.
Below in conjunction with figure, the invention will be further described with embodiment.
