The clamping fixture comprises a clamping fixture body; the center of the clamping fixture body is provided with a central positioning block matched with a working table, and the inner side thereof is provided with a positioning block matched with the parts; the positioning block and a cylindrical bore on the part are positioned by adopting edge-cutting diamond pins; the peripheral direction of the clamping fixture body is provided with a keyway positioning block matched with a T-shaped groove of the working table; the position on the horizontal surface at the peripheral direction of the clamping fixture body, opposite to the keyway positioning block, is provided with positioning pin holes; the positioning pin hole, the keyway positioning block and the positioning block are coincided at the central line of the horizontal surface of the clamping fixture body; and the clamping fixture body is also provided with an inspecting gauge block which is connected with the clamping fixture body by the keyway on the clamping fixture body. The clamping fixture has convenient positioning when in use, can guarantee the processing quality of thin-wall holes and control the distance from the supporting positioning surface to the center of the part, reduces the working intensity of workers due to convenient and flexible operation and improves the efficiency by more than 4 times compared with the adoption of marking processing.

Description

Thin-walled parts brill, bore hole and finish-milling locating surface mold
Technical field
The utility model relates to a kind of thin-walled parts hole and locating surface processing accessory, relates in particular to a kind of thin-walled parts brill, bore hole and finish-milling locating surface mold.
Background technology
Thin-walled parts is applied in the industrial production because of it has characteristics such as in light weight, economical with materials, compact conformation increasingly extensively.But the processing of thin-walled parts is difficulty relatively, and reason is the thin-walled parts poor rigidity, weak strength, and work in-process very easily is out of shape, and the form and position tolerance of part is increased, and is difficult for guaranteeing the crudy of part.
Boring or bore hole are generally adopted in the processing in thin-walled hole, because parts good rigidity such as the main shaft of boring machine, workbench, precision is higher, so can process all higher hole of size, shape and positional precision on boring machine, is particularly useful for the fine finishining of thin-walled hole and end face.But no matter hole or bore hole, because boring or boring equipment complex structure, the process-cycle of thin-walled parts is long, requires operating personnel's technical merit higher, and location inconvenience when using, and all is difficult to guarantee the crudy in thin-walled hole.
The utility model content
The purpose of this utility model is, a kind of thin-walled parts brill, bore hole and finish-milling locating surface mold are provided, and the location was convenient when this kind mold used, and can guarantee the Working position degree of thin-walled parts radial hole and control the distance of supporting locating surface apart from the part center.
The technical solution adopted in the utility model is: a kind of thin-walled parts bores, bore hole and finish-milling locating surface mold, this kind mold includes the mold body, mold body center is provided with the centralized positioning piece that cooperates with workbench, mold body inboard be provided with cooperate with part locating piece, cylindrical hole on described locating piece and the part adopts the finger setting of chamfered edge rhombus, the mold body is circumferentially with the keyway locating piece that cooperates with workbench T type groove, the mold body circumferentially is provided with dowel hole in the horizontal plane position relative with the keyway locating piece, dowel hole, keyway locating piece and locating piece also are provided with the inspection gauge block that is connected with the mold body by the keyway on the mold body in the central lines of mold body horizontal plane on the described mold body.
Further, described dowel hole rear end is provided with feeler block.
The beneficial effects of the utility model are:
1. the setting of centralized positioning piece and keyway locating piece, the free degree of the controlled tool direction of rotation of making base, thus reach the accurate location of control mold on workbench.
2. the setting of the locating piece that cooperates with part, chamfered edge rhombus pin and dowel hole can guarantee when processing thin-walled part, and radial hole is by the axis of workpiece center, thus the free degree of control part direction of rotation.
3. check the setting of gauge block, can control the distance of supporting locating surface apart from the part center.
Description of drawings
Fig. 1 is that the utility model structure is used schematic diagram.
Reference numeral: the 1st, the centralized positioning piece, the 2nd, chamfered edge rhombus pin, the 3rd, the keyway locating piece, the 4th, part, the 5th, the mold body, the 6th, locating piece, the 7th, pressing plate, the 8th, check gauge block, the 9th, feeler block, the 10th, dowel hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of thin-walled parts bores, bore hole and finish-milling locating surface mold, include mold body 5, mold body 5 centers are provided with the centralized positioning piece 1 that cooperates with workbench, mold body inboard be provided with cooperate with part locating piece 6, locating piece 6 is located with the cylindrical hole employing chamfered edge rhombus pin 2 on the part, mold body 5 is circumferentially with the keyway locating piece 3 that cooperates with workbench T type groove, the horizontal plane position that the mold body is circumferentially relative with keyway locating piece 3 is provided with dowel hole 10, dowel hole 10 rear ends are provided with feeler block 9, dowel hole 10, keyway locating piece 3 and locating piece 6 also are provided with the inspection gauge block 8 that is connected with the mold body by the keyway on the mold body in the central lines of mold body horizontal plane on the mold body.
On boring table, accurately locate the centralized positioning piece 1 that cooperates with boring table, its tolerance fit employing H6/h5 for guaranteeing mold.
Because part is a thin-wall part, for reducing clamping deformation, install at part and to adopt clamping and cylindrical location immediately, pass through the axis of workpiece center in order to guarantee radial hole, the locating piece 6 that cooperates with part, cooperate and adopt the control of H6/js5 interference fits, and utilize the accurately machined cylindrical hole of part end face location, and with the free degree of chamfered edge rhombus pin 2 control part direction of rotation, thus the free degree of control part six direction, M24 screw rod by around part compresses part with pressing plate.The center of the center of dowel hole 10 by locating piece 6 is not more than 0.025mm to locating piece 6 position errors, bore, before the boring part radial hole, by boring machine guide pin bushing centering dowel hole 10 can bore, the bore hole radial hole.
Check that gauge block tip to face distance locating piece 6 its tolerance when frock designs is 0.03mm, when fine finishining part supporting locating surface, adopt micrometric depth gauge to measure and check that gauge block is to the distance that supports locating surface.
After adopting the utility model, than adopting its productivity ratio of line processing can improve more than 4 times.
