Description

A kind of normal director

Technical field

The invention belongs to general manufacturing technologies, are related to a kind of surface normal centering utensil, i.e. normal director.

Background technology

At present, hang down hole, tapping centering are processed on plane, single-curved surface, hyperbolic surface part, particularly in larger workpiece On operated with hand-operated tools, without specific purpose tool ensure, can only by virtue of experience and feel, special fixture is of high cost, poor universality.

Invention content

The purpose of the present invention is：It is proposed a kind of ginseng that can ensure quick and precisely to find different shape surface arbitrary point normal According to tool.

The technical scheme is that：A kind of normal director, it is characterised in that：It includes stent (1), angle square (2), leads To sliding block (3) and lock-screw component (4)；Stent (1) is bilateral symmetry, and locating slot is set in symmetrical centre line position, Extend support feet from locating slot to both sides, angle square (2) is placed in the locating slot of stent (1), and angle square (2) can be at this It is slided above and below in locating slot, angle square (2) includes vertical portion and lateral part, L-shaped, and the vertical portion of angle square (2) includes Waist through hole so that lock-screw component (4) can pass through the waist through hole and slide, and the vertical portion of angle square (2) further includes Milling square groove, the guide runner (3) is in the milling square groove；Guide runner (3) includes front and back, and front is tool Guide surface, the back side are T shape sliding slots so that one end of lock-screw component (4) can be limited in the T shapes sliding slot and slide.

It is an advantage of the invention that：It can guarantee the method for arbitrary point on the different curvature curved surface for rapidly and accurately find R48~∞ Line, improve drilling, tapping vertical precision, using this practicality invention, solve for a long time the drilling of heavy parts surface, tapping with By means of experience and observation, there is no the problem of quantification tool, help to improve product quality and processing efficiency.

Specific embodiment

The invention of this reality is described in further details below.It is the exploded view of normal director referring to Fig. 1, it includes branch Frame 1, angle square 2, guide runner 3 and lock-screw component 4；Stent 1 is symmetrical structure, sets and positions in symmetrical centre line position Slot extends support feet from locating slot to both sides, and angle square 2 is placed in the locating slot of stent 1, and angle square 2 can be fixed at this It is slided above and below in the slot of position, angle square 2 includes vertical portion and lateral part, and L-shaped, the vertical portion of angle square 2 is led to kidney-shaped Hole so that lock-screw component 4 can pass through the waist through hole and slide, and guide runner 3 includes front and back, and front is work The guide surface of tool, the back side are T shape sliding slots so that one end of lock-screw component 4 can be limited in the T shapes sliding slot and slide.

Particularly, stent 1 is the symmetrical stent of herringbone that support feet angle is 100 °, is positioning element, material is 45# steel, thickness 10mm, using linear cutter shape, milling depth 7mm square grooves bore 13 hole of Φ, bore 4 Φ, 4,8 Φ 5 Lightening hole (such as Fig. 4 a)；Angle square 2 is 90 ° of L-shaped parts, is positioning element, and material is 45# steel, wire cutting L-shaped shape, it is preferred that The vertical portion of angle square 2 further includes milling square groove, and the guide runner 3 is placed in the milling square groove, it is furthermore preferred that angle square 2 It the bottom of lateral part can be with milling into 120 ° of angle faces (such as Fig. 5 b)；Guide runner 3 is workpiece, can be to be processed as difference The hole of diameter provides the guiding of tool with tapping, and material is 45# steel, with linear cutter part, it is preferred that guide runner 3 wraps V-shaped groove, U-lag or drill bushing are included, by taking V-shaped groove as an example, the V-shaped groove angle line is the normal reference line of measured part, and two press from both sides Edged surface is the plane of reference, and the aperture that drill bushing processes hole as needed specially processes, and can improve the work efficiency and precision of drilling；Locking screw Screw assembly 4 includes screw and nut (Fig. 7 a and 7b), and purposes is and locking bracket, angle square and guide runner.

The present invention application method be：1, lock-screw component is unclamped, enables each component activity；2, it promotes angle square and leads To sliding block, two stabilizer blades of stent is made to fall on curved surface (plane), it is substantially vertical；3, angle square is put down, adjustment stent posture makes angle The plain line of ruler base and surface of revolution (or face of plane) coincide, it is impossible to which there are gaps；4, lock-screw component consolidates each component It is fixed motionless；5, it can be moved on the surface of same curvature and take office meaning point, ensure that two fulcrum of stent, angle square base most baseline and curved surface are kissed It closes, V-shaped groove angle line, the baseline of U-lag or the axis of Special drill bushing, is exactly the normal in song (flat) face.
