Abstract

The utility model discloses a clamping tool used during milling a hexagon nut. The clamping tool comprises a pair of clamp plates and a hexagon screw arranged between the clamp plates, wherein an external thread of a stud of the hexagon screw is in threaded fit with an internal thread of a workpiece; a group of V-shaped grooves with 120 DEG included angles and uniformly distributed along a straight line are formed in opposite end surfaces of the two clamp plates; the spacing between bottoms of every two adjacent V-shaped grooves is greater than the spacing between two opposite positioning surfaces at the head part of the hexagon screw; and the V-shaped grooves of the two clamp plates are in one-to-one correspondence to form a clamping space for clamping the head part of the hexagon screw. The clamping tool with the structure relies on positioning fit between the nut of the hexagon screw and the clamping space, ensures the accuracy of the rotation angle of the workpiece, consequentially reduces the machining error of each positioning surface of the workpiece, and ensures that the six positioning surfaces of the machined hexagon nut meet the specified requirement.

Description

The clamping tooling that a kind of hex nut Milling Process is used
Technical field
The utility model relates to six aspect Milling Process of hex nut, is specifically related to the clamping tooling that a kind of Milling Process is used.
Background technology
Hex nut is to use with bolt, screw fit, works the parts of the effect of being fixedly connected with, and as standard component, six aspects of hex nut must satisfy specification requirement.Six locating surface processing of tradition hex nut, adopt single locating surface to carry out one by one the method for milling, first being processed directly fixes to clamp workpiece with clamping device, because clamping device only plays clamping action, can't directly position workpiece, face of every processing all wants turning of work piece again to manually locate, this just easily produces larger error, finally cause the symmetry of any two opposite faces of the hex nut after the processing lower, precision does not reach requirement yet, and a face of a face carry out milling, working (machining) efficiency is also low.
The utility model content
The purpose of this utility model provides the clamping tooling that a kind of hex nut Milling Process is used, and can't directly position workpiece in order to solve existing clamping device, the problem that causes the hex nut after the processing not meet the demands.
The utility model adopts following technical scheme: the clamping tooling that a kind of hex nut Milling Process is used, comprise a pair of clamping plate and be located at hex screw between the clamping plate, the external screw thread of the double-screw bolt of described hex screw is used for the internal thread threaded engagement with workpiece, all offering one group on the opposing end surface of two clamping plate is 120 ° V-shaped groove along the uniform angle of straight line, the bottom land spacing of adjacent two V-shaped grooves is used for the spacing greater than two relative positioning faces of head of hex screw, and the V-shaped groove of two clamping plate is the corresponding grasping part that is formed for clamping hex screw head one by one.
Also be fixed with on the double-screw bolt of described hex screw and paste friction tight for keeping off the edge with workpiece spindle to the annular that block cooperates with the head of hex screw.
The clamping tooling that the hex nut Milling Process of employing said structure is used, owing to offering respectively one group of angle on the opposing end surface of two clamping plate and be 120 ° V-shaped groove, when two clamping plate are oppositely arranged, two relative V-shaped grooves cooperate the grasping part that forms just in time adaptive with the head of hex screw, when two clamping plate are applied relative active force, grasping part can be realized the clamping and positioning of hex screw, what simultaneously grasping part can guarantee that the anglec of rotation of hex screw is workpiece rotates to the anglec of rotation of another locating surface by a locating surface, therefore can guarantee that workpiece is transformed into the locating surface of another direction fast by the locating surface of a direction, in addition, the double-screw bolt of hex screw can be realized the detachable fixing of workpiece, thus the accurate location of realizing workpiece.The clamping tooling of this structure, rely on the nut of hex screw and the location of grasping part to cooperate, guarantee the accuracy of workpiece rotating angle, finally reduce the mismachining tolerance of each locating surface of workpiece, guaranteed six locating surface requirements up to specification of the hex nut that processes.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the assembling schematic diagram of hex screw and workpiece.
The specific embodiment
The embodiment of the clamping tooling that the utility model hex nut Milling Process is used: as shown in Figure 1 and Figure 2, comprise clamping plate 1 and hex screw 2, the internal thread threaded engagement of the external screw thread of the double-screw bolt of hex screw 2 and workpiece 4, workpiece 4 is screwed on the double-screw bolt of hex screw 2, and then realizes the location of workpiece 4.Offer respectively six on the opposing end surface of two clamping plate 1 along the uniform V-shaped groove 11 of straight line, the angle of V-shaped groove 11 is 120 °, and the bottom land spacing of two adjacent V-shaped grooves 11 is greater than the spacing of two relative positioning faces of workpiece 4 heads, when two clamping plate 1 are oppositely arranged, V-shaped groove 11 separately is six grasping parts of corresponding formation one by one, the head of six hex screws 2 is put into respectively grasping part, grasping part is just in time adaptive with the head of hex screw 2, by clamping two clamping plate, can realize the clamping and positioning of hex screw 2, the bottom land spacing of adjacent two V-shaped grooves 11 can prevent that greater than the spacing of two relative positioning faces of workpiece head two adjacent hex screws from interfering.
Add man-hour, in order to prevent workpiece 4 because stressed generation rotation causes mismachining tolerance, be fixed with on the double-screw bolt outer peripheral face of hex screw 2 with the friction tight annular of head subsides of hex screw 2 and keep off along 3, the annular gear can prevent the further axially precession of workpiece along 3.
When above-described embodiment specifically uses, quantity according to grasping part, six workpieces to be processed are screwed in respectively on the double-screw bolt of six hex screws 2 until hold out against along 3 with the annular gear, then the head of six hex screws 2 is put into respectively six grasping parts, and make double-screw bolt away from nut one end up, by the vice on the milling machine two clamping plate 1 are clamped.Add man-hour, adopt double milling cutter that two unidirectional locating surfaces of each workpiece to be processed are processed simultaneously, can finish the time processing of two relative positioning faces of workpiece to be processed, then unclamp vice, the rotation hex screw, repeat said process, finish the processing of two other relative positioning face of workpiece to be processed, until six whole millings of locating surface are complete.In process, the annular gear is along preventing that workpiece to be processed from rotating the mismachining tolerance that causes because being subject to the milling active force.
