Abstract
The utility model discloses a hole digger which is formed by a guide column, an iron guide rod and a magnet. The magnet belongs to a component used in a matching mode, a cylindrical hole with the diameter being 1 mm is formed in a center opening of the top of the guide column, the depth of the cylindrical hole is smaller than the height of the guide column, the axis of the cylindrical hole coincides with the axis of the guide column, threads are tapped at the top of the cylindrical hole, the iron guide rod is inserted into the cylindrical hole, the top end of the iron guide rod is a mark painting end, the iron guide rod is in clearance fit with the cylindrical hole, and the magnetic force formed by the magnet and the iron guide rod is larger than the weight of the iron guide rod. The hole digger can effectively solve the problem of hole digging under the condition that a machined part is poor in path, and meanwhile guarantees the coaxiality and the perpendicularity of hole digging.
Description
Technical field
The utility model relates to machine tools, relates to specifically a kind ofly for aircraft assembling structure, not opening wide position and drawing aperture apparatus.
Background technology
At aviation field, when machine adds part and is connected with sheet metal component, the hole on sheet metal component is usually that the Kong Yinkong adding on part by machine makes.Due to the covering of sheet metal component, we often cannot see position, hole, can only on sheet metal component, leave marks so that drilling with the hole that pen adds part by machine.If but that machine adds part path is bad, the hole that hand cannot stretch into or machine adds on part is not that through hole just cannot ensure axiality and the perpendicularity of drawing hole.
Summary of the invention
The utility model object is to overcome deficiency of the prior art, and hole guiding device a kind of simple in structure, easy to operate is provided, and can add under the condition that part path is bad and hand cannot stretch into and draw hole at machine, and can guarantee axiality and the perpendicularity in hole.
The technical solution of the utility model: a kind of hole guiding device, by guide pillar, ironly lead rod and magnet forms, magnet belongs to and is used in conjunction with parts, it is 1mm that guide pillar top center opening is provided with diameter, the degree of depth is less than the cylindrical hole of guide pillar height, the axis of cylindrical hole and the dead in line of guide pillar, screw thread has been attacked at cylindrical hole top, in cylindrical hole, be inserted with the iron rod of leading, it is iron that to lead excellent top be that mark is smeared end, iron rod and the cylindrical hole matched in clearance led, magnet is led the magnetic force that clavate becomes and is greater than the iron excellent weight of leading with iron.
On the external diameter of described guide pillar top, attacked screw thread.
It is described that iron to lead excellent diameter be 0.95mm-0.98mm.
The utility model is simple in structure, easy to use, by magnet, excellent guide effect is led to iron in iron excellent suction and the guide pillar hole of leading, and makes to draw hole precision and greatly improves, thereby guaranteed to draw axiality and the perpendicularity in hole.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of guide pillar in the utility model.
Fig. 2 is iron main TV structure schematic diagram of leading rod in the utility model
In figure: guide pillar 1 and lead rod 2.
The specific embodiment
The utility model can specifically be implemented by the technical scheme in summary of the invention, by the following examples can the utility model will be further described.
Embodiment 1: a kind of hole guiding device, by guide pillar 1, iron lead rod 2 and magnet form, magnet belongs to and is used in conjunction with parts, and it is 1mm that guide pillar 1 top center opening is provided with diameter, and the degree of depth is less than the cylindrical hole of guide pillar 1 height, the dead in line of the axis of cylindrical hole and guide pillar 1, screw thread has been attacked at cylindrical hole top, is inserted with the iron rod 2 of leading in cylindrical hole, and iron top of leading rod 2 is that mark is smeared end, iron rod 2 and the cylindrical hole matched in clearance led, magnet and iron magnetic force of leading rod 2 formation are greater than the iron weight of leading rod 2.
On described guide pillar 1 top external diameter, attacked screw thread.
Described iron diameter of leading rod 2 is 0.95mm-0.98mm.
Design application process:
1. be illustrated in figure 1 the guide pillar 1 of hole guiding device, cylindric, diameter d customizes according to drawing hole demand with height h.It is 1mm that guide pillar 1 center is drilled with diameter, the cylindrical hole of height < h, and screw thread has been attacked at the top of cylindrical hole;
2. the iron rod 2 of leading of placing a diameter 1mm in the cylindrical hole at guide pillar 1 center, the iron rod 2 of leading can freely be come in and gone out with the iron rod 2 of leading with the matching relationship of cylindrical hole, gap little being as the criterion of trying one's best;
3. with marking pen, iron, lead excellent 2 tops and smear;
4. guide pillar 1 is put into hole to be drawn, guide pillar 1 will have certain tight plucked instrument with coordinating of hole to be drawn, and makes the top end face of hole guiding device and the end face in hole to be drawn;
5. will need the metal plate part of drilling to adjust position by product drawing requirement, magnet is placed on to part top, under the attraction of magnet, ironly leads the marking that rod 2 can knock the pen that leaves marks on panel beating, this marking is the center of circle in hole, only need be to be imprinted as center of circle drilling;
6. the screw thread that is finally screwed into hole guiding device centre bore top by screw is extracted hole guiding device;
7. if hole to be drawn is screwed hole, for improving, draw hole precision, also can on guide pillar 1 external diameter, make screw thread and coordinate with screwed hole to be drawn.
Claims (3)
1. a hole guiding device, by guide pillar (1), iron rod (2) and the magnet formation led, magnet belongs to and is used in conjunction with parts, it is characterized in that: it is 1mm that guide pillar (1) top center opening is provided with diameter, the degree of depth is less than the cylindrical hole of guide pillar (1) height, the dead in line of the axis of cylindrical hole and guide pillar (1), screw thread has been attacked at cylindrical hole top, in cylindrical hole, be inserted with the iron rod (2) of leading, iron top of leading rod (2) is that mark is smeared end, iron rod (2) and the cylindrical hole matched in clearance led, magnet and iron magnetic force of leading rod (2) formation are greater than the iron weight of leading rod (2).
