Abstract

The utility model discloses a clamping jig for milling a hexagonal bolt, which comprises front and rear clamp bodies, wherein through grooves extending along the vertical direction and used for having engagement fit with the outer circumferential surface of a screw of the hexagonal bolt to be machined are formed on the end faces of the opposite ends of the front and rear clamp bodies; and the through grooves of the front and rear clamp bodies are correspondingly matched with each other to form a clamping space for clamping the hexagonal bolt to be machined. By clamping the hexagonal bolt to be machined in the clamping space, the stability and stress balance of the hexagonal bolt to be machined are guaranteed during machining, and the machining errors are reduced.

Description

A kind of hex bolts Milling Process is used clamping tooling

Technical field

The utility model relates on milling machine the Milling Process of hexagon bolt head, is specifically related to process the clamping tooling of usefulness.

Background technology

Hex bolts is owing to possess the locking effect of good connection; Receive application widely in fields such as Aeronautics and Astronautics, boats and ships, electronics, defence; The relevant criterion of hex bolts requires its connection, quick and easy for installation and uniformity stable; This is just very strict to the size, Geometrical Tolerance Principle on six planes of the hexagon bolt head after the processing, and six planes must be controlled within the very tight margin of tolerance, so the processing method on six planes is particularly important.Six plane surface processing methods of existing hex bolts adopt two the direct clamping of clamp body hex bolts to be processed; Through the Milling Process of milling cutter to a face of a face of hex bolts to be processed; Owing to have only the front and back side of hex bolts to be processed to be held; Discontinuity equalization in milling process, hex bolts to be processed is taken place about skew, cause six planes after the processing to have big mismachining tolerances.

The utility model content

The purpose of the utility model provides a kind of hex bolts that can guarantee and when Milling Process, keeps stable Milling Process to use frock.

The utility model adopts following technical scheme: a kind of hex bolts Milling Process is used clamping tooling; Comprise forward and backward clamp body; Offer being used for and the identical groove that cooperates of the screw rod outer peripheral face of hex bolts to be processed of vertically extending on the end face of the opposite end of forward and backward clamp body respectively, and the groove corresponding matching of forward and backward clamp body is formed for the grasping part of clamping hex bolts to be processed.

Said grasping part is along even at least one of arranging of left and right directions.

Said forward and backward clamp body is cuboid.

Adopt the frock of said structure; Owing to offer the groove that coincide and cooperate with the screw rod of hex bolts to be processed on the forward and backward clamp body respectively; And the groove corresponding matching of forward and backward clamp body has formed the grasping part of clamping hex bolts to be processed; Clamp through hex bolts to be processed is put into grasping part, guaranteed the stable and stress balance of hex bolts to be processed in process engineering, reduced mismachining tolerance.

In addition, said grasping part is a plurality of, adds man-hour, and a plurality of hex bolts to be processed of a clamping have improved working (machining) efficiency.

Description of drawings

Fig. 1 is the structural representation of the embodiment of the utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the user mode figure of the utility model.

The specific embodiment

The utility model hex bolts Milling Process is with the embodiment of clamping tooling: shown in Fig. 1-3; This frock is applied on the horizontal milling machine; Two clamp bodies of this frock are respectively fore-clamp concrete 11 and rear jig body 12; Assemble for ease and use, fore-clamp concrete 11 is that rectangular structure and size are consistent with rear jig body 12.Offer the groove 111 that coincide and cooperate with screw rod outer peripheral face hex bolts 3 to be processed vertically that extend on the end face of one end of the relative rear jig body 12 of fore-clamp concrete 11; Groove 111 is evenly spaced apart a plurality of along concrete 11 left and right directions of fore-clamp; The end face of one end of the relative fore-clamp concrete 11 of rear jig body 12 offers the groove 121 with the corresponding one by one setting of groove 111, and corresponding two grooves 111 cooperate the grasping part 2 that has formed clamping hex bolts 3 to be processed with groove 121.During concrete operations,, hex bolts to be processed is inserted clamping in each grasping part 2 one by one through parallel jaw clamping fore-clamp concrete 11 and rear jig body 12.

In the foregoing description; Said groove 111 and groove 121 corresponding matching one by one form a plurality of grasping parts 2; Time processing can a plurality of hex bolts 3 to be processed of clamping, have improved working (machining) efficiency, in other embodiments; A groove 111 and a groove 121 also can be set, and cooperate grasping part 2 of formation.

The foregoing description at first is fixed on parallel jaw on the workbench of horizontal milling machine in use, and fore-clamp concrete 11 and rear jig body 12 are placed in the jaw of parallel jaw; Then hex bolts 3 to be processed is put into each grasping part 2 one by one, tighten parallel jaw, adopt double milling cutter processing pair of parallel plane earlier; Unclamp vice then,, tighten parallel jaw 60 ° of each hex bolts 3 rotations to be processed; Beginning is processing for the second time; Repeat above-mentioned steps, accomplish processing for the third time, accomplish the processing on six planes at last.
