Abstract
The utility model relates to a milling pocket clamp, particularly to a coaxial milling pocket clamp for a holding rack with uniform pressure, and belongs to the field of machining precise clamps. The coaxial milling pocket clamp comprises a tire seat and a tire cover, wherein the holding rack is placed between the tire seat and the tire cover; a positioning hole is respectively formed in the center line of each of the tire seat and the tire cover; a limiting hole is respectively formed in the fourth line of each of the tire seat and the tire cover; a limiting shaft penetrates through the positioning hole of the tire cover, and is fixed on the positioning hole of the tire seat; a positioning shaft penetrates through the positioning holes in the tire cover and the tire seat, and is arranged between the tire cover and the tire seat; the clamping deformation of the milling pocket of the holding rack is analyzed and tested, the main factor for the deformation of the pocket can be conformed, which is that the pressing force of the clamp for processing the pocket is not uniform, a concentric positioning hole is processed in the center line position of the tire seat and the tire cover at the same time, the positioning shaft is mounted, so that the coaxiality of the tire seat and the tire cover under the action of the positioning shaft is guaranteed to be uniform, meanwhile one limiting hole is processed so as to mount the limiting shaft, the tire cover rotates in the axial direction of the limiting shaft, the mounting at the same position in each use is ensured, and the stability of the manufacturing process is ensured.
Description
technical field
The utility model relates to a kind of milling pocket hole fixture, specifically relates to the coaxial milling pocket of a kind of equalization of pressure retainer hole fixture, and it belongs to machined precise clamp field.
background technology
In the structure of machining high-precision retainer, there is a kind of copper cage to belong to the sophisticated product of special construction, its wall thickness is very thin, dimensional tolerance, behavior tolerance is very strict, and during due to processing retainer pocket hole, whole retainer is easy to produce distortion in process, the diameter, the position degree etc. that affect pocket hole can not meet technological requirement, need special precise clamp to guarantee product quality.
summary of the invention
In view of the defect that prior art exists, the utility model provides the coaxial milling pocket of a kind of equalization of pressure retainer hole fixture, realizes clamping product accurate, and product-free is out of shape, and reaches the object of sophisticated product standard.
For achieving the above object, the technical scheme that the utility model adopts is to be the coaxial milling pocket of equalization of pressure retainer hole fixture, and it comprises: placenta and tire lid; Between placenta and tire lid, place retainer; On placenta and tire lid center line, be respectively equipped with locating hole; Placenta and tire lid 1/4th lines are provided with spacing hole; On the limit shaft locating hole with placenta fixing through the locating hole of tire lid, locating shaft, through the locating hole of tire lid and placenta, is placed between tire lid and placenta; Locating shaft is provided with middle through hole, and trip bolt schedules locating shaft state on placenta through through hole in locating shaft, and corner nut coordinates with trip bolt, between corner nut and tire lid, is provided with plain washer.
The use procedure of the coaxial milling pocket of described equalization of pressure retainer hole fixture: placenta is fixed on lathe, adjust Working position, locating shaft is installed in the locating hole of placenta, locating shaft is that high-precision gap coordinates with placenta locating hole, and it is more reliable that rotational positioning axle makes its cooperation gently, the fastening bolt of screwing on, gently retainer is placed on again in placenta holddown groove, tire lid is inserted in locating shaft and is close to retainer, and position mounting limit axle is adjusted in rotation, puts plain washer and tightens hex nut; Retainer is fixed between tire lid and placenta, is namely fixed on equipment, neither has axial float, does not also have circumferential rotation, starts milling retainer pocket hole.
Described placenta locating hole center is provided with trip bolt locating hole, in trip bolt locating hole, is provided with screw thread, and described screw thread matches with trip bolt screw thread.
The utility model has the advantage of: retainer milling pocket hole is clamped to deformation analysis, test, confirm that pocket bore deformation main cause is inhomogeneous the causing of clamp pressing power in processing pocket hole, process a concentric locating hole at the position of center line of placenta and tire lid simultaneously, a locating shaft is installed, placenta and tire are covered and under the effect of locating shaft, ensure that axiality is consistent, process a spacing hole simultaneously and be used for mounting limit axle, with the spacing axial-rotation of tire lid, while ensureing each use, all install in same position, ensure the stable of process.When in processing the pocket hole, retainer need to be placed between fixture placenta and tire lid and clamp processing, placenta and tire lid are realized processing simultaneously, ensure placenta tire lid and base axiality, the depth of parallelism, perpendicularity, make retainer bear even clamping force, reach the requirement of pocket hole location technological requirement.
