Abstract

The invention relates to an overturning type digital control milling clamp comprising a rotary handle (I), two rotary handles (II), two positioners, positioning holes (I), two rotating discs, two rotating shafts, two nuts, two positioning pins, two positioning support parts, a clamp plate, four positioning holes (II), two cylindrical pins and two upright columns, wherein a positioning hole (II) is respectively arranged at the clamp plate and four corners; the two upright columns are respectively arranged both ends of the clamp plate, and the upper end of each upright column is provided with the rotating shaft and the positioner; one ends of the rotating shafts are provided with the rotating discs; the edges of the rotating discs are provided with the positioning holes (I); the rotating discs are provided with the positioning support parts; the positioning support parts are provided with the nuts and the positioning pins; the upright columns are provided with the rotary handles (II); the cylindrical pins are arranged between the rotating shafts and the rotating discs; and the other end of one of the rotating shafts is provided with the rotary handle (I). The invention completes the processing of a part with multi-angle surfaces through one-time correction and one-time clamping, thereby reducing the repeated positioning errors, enhancing the processing accuracy, decreasing the tooling number and reducing the processing cost.

Description

Overturning type digital control milling clamp

Technical field:

The invention is the anchor clamps that are used for multi-angle surface parts clamping digital control milling.

Background technology:

In the digital control milling process, for processed part, need be by the frock clamping, when the part that runs into the multi-angle face, need many cover frock multiple clamping, centering working origin, finish the processing of part different angles face,, waste time and energy because of multiple clamping, centering part to be processed working origin; There is the resetting error, influences part processing precision.

Summary of the invention:

The purpose of the invention provides a kind of processing multi-angle surface parts, reduces the overturning type digital control milling clamp of frock quantity and clamping times; The purpose of the invention is to realize by following technical scheme: overturning type digital control milling clamp is characterized in that being made of rotary handle I, two rotary handle II, two locators, locating hole I, two rotating disks, two rotating shafts, two nuts, two alignment pins, two positioning supporting parts, jig plate, four locating hole II, two straight pins and two columns; Jig plate and four jiaos of places make a locating hole II respectively; Two columns are contained in respectively on the two ends of jig plate, rotating shaft and locator are installed in each column upper end, rotating shaft one end dress rotating disk, locating hole I is made at the edge of rotating disk, positioning supporting part is installed on the rotating disk, nut and alignment pin are installed on the positioning supporting part, rotary handle II is installed on column, between rotating shaft and rotating disk, straight pin is installed; A rotating shaft other end is therein installed rotary handle I.

The advantage of the invention: realize the processing that No. one time clamping is finished the multi-angle surface parts, only need digital control processing initial point of centering, reduce the resetting error, improved machining accuracy; Reduce frock quantity, reduced processing cost; Reduce in the digital control processing frock and prepared non-cutting time.

Among the figure: 1, rotary handle I 2, rotary handle II 3, locator 4, locating hole I 5, rotating disk 6, rotating shaft 7, nut 8, alignment pin 9, positioning supporting part 10, multi-angle surface parts 11 suspension ring 12, jig plate 13, locating hole II 14, straight pin 15, column

The specific embodiment:

Overturning type digital control milling clamp is made of rotary handle I, two rotary handle II, two locators, locating hole I, two rotating disks, two rotating shafts, two nuts, two alignment pins, two positioning supporting parts, jig plate, four locating hole II, two straight pins and two columns; Jig plate and four jiaos of places make a locating hole II respectively; Two columns are contained in respectively on the two ends of jig plate, rotating shaft and locator are installed in each column upper end, rotating shaft one end dress rotating disk, locating hole I is made at the edge of rotating disk, the hole count of locating hole I is fixed as required, and positioning supporting part is installed on the rotating disk, and nut and alignment pin are installed on the positioning supporting part, rotary handle II is installed on column, between rotating shaft and rotating disk, straight pin is installed; A rotating shaft other end is therein installed rotary handle I.

Four suspension ring are contained on the jig plate, are convenient to lifting.

Multi-angle surface parts two ends are contained on two positioning supporting parts, locate with alignment pin, use nut check, rotate rotating disk drive multi-angle surface parts and turn to required machining angle position, insert by the locating hole II on two rotating disks with locator, orientation angle, rotation rotary handle I, countershaft and rotating disk carry out axial locking, rotation rotary handle II countershaft and rotating disk are radially locked, and finish clamping process.Change the machining angle of multi-angle surface parts, rotation rotary handle II, unclamp the radially locking of rotating shaft and rotating disk, rotation rotary handle I, unclamp the axial locking of rotating shaft and rotating disk, extract locator from two rotating disks, with locator by the locating hole I orientation angle on two rotating disks, rotating rotating disk drive angle part passs on moving to required machining angle position, pass through locating hole I orientation angle on two rotating disks with locator, rotation rotary handle I countershaft and rotating disk carry out axial locking, rotation rotary handle II radially locks passing on axle and rotating disk, finishes clamping process, with this process, frock can be adjusted different angles, realizes that upset reaches in 360 ° of scopes.
