Description
Technical field
The utility model discloses a kind of high accurate hole apart from the processing position indicator, belong to the technical field that clamps machining tool.
Background technology
Boring is one of action of running into often in the pincers worker operation, for the porous operation that has pitch-row to require between the Kong Yukong, is technical difficulty maximum in the pincers processing.According to present processing situation, following several form processing is arranged, but all there are different pluses and minuses: 1, line location drilling: according to the drawing specification requirement, on workpiece, mark the cross position line in hole, and strike the sample dotting punch in cross position line junction, the Working position in clear and definite its hole, locate, clamp, hole in the position according to the sample dotting punch on drilling machine then.But the machining accuracy of pitch-row is lower, and beyond 0.30mm, difficulty reaches processing request to the pitch-row error substantially.2, measure plug with two and detect boring: equally also will rule, locate, the position in clear and definite its hole, subdrilling, cut with scissors what a hole, insert a plug, in the drill chuck of drill press spindle, also insert an other plug then, detect the actual size of two plugs with measurer, when actual size=pitch-row size+one diameter of mandrel, the Working position in another one hole has just been determined.The machining accuracy of this handle hole distance is than higher, and the pitch-row error is substantially in 0.10mm, but its troublesome poeration, proof time waste, unsuitable small lot batch manufacture.3, with pilot pin machining hole distance: the pilot pin clamping in the drill chuck of drill press spindle, is come rule position with dotting punch of centering with the tip of pilot pin, determine the Working position in hole with it.Though process time is shorter, its machining accuracy is lower, and the pitch-row error is substantially beyond 0.30mm, because it relates to multiple reason.4, process with numerical control (machining center) equipment: though precision can reach its pitch-row required precision fully, equipment cost is very big, be unfavorable in the production environment of small lot, because of its processing cost too high.
The utility model content
In order to overcome above-mentioned shortcoming, the high accurate hole that the utility model provides that a kind of pitch-row tolerance can be controlled within the 0.05mm, low processing cost and process time are short is apart from the processing position indicator.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of high accurate hole comprises that apart from the processing position indicator interior angle is the L type gauge block at right angle, wherein forms the vertical measuring surface of interior angle, laterally measuring surface is the measuring basis face, and L type gauge block is provided with positioner.
Described positioner comprises first positioning through hole that is arranged on the L type gauge block vertical portion, be arranged on second positioning through hole on the L type gauge block transverse part, be arranged on the 3rd positioning through hole of vertical portion and transverse part intersection, wherein is combined with first bolt, second bolt, the 3rd bolt respectively in first positioning through hole, second positioning through hole, the 3rd positioning through hole.
Offer technology groove on the handing-over end between described vertical measuring surface, the horizontal measuring surface.
Described first positioning through hole, second positioning through hole all are oval shape.
The bottom surface of described L type gauge block is the measuring basis face.
The utility model is simple in structure, low cost of manufacture, pitch-row tolerance can be controlled within the 0.05mm, low processing cost and process time are short, in being applicable to, in the small serial production occasion, be more conducive to manufacturing hole apart from drill jig.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A-A among Fig. 1 is to cutaway view;
Structural representation when Fig. 3 carries out processing work for the utility model is installed on the table surface.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model high accurate hole comprises that apart from the processing position indicator interior angle is the L type gauge block 3 at right angle, wherein forms the vertical measuring surface 9 of interior angle, laterally measuring surface 8 is the measuring basis face, and L type gauge block 3 is provided with positioner.
Further setting as this case, positioner comprises first positioning through hole 1 that is arranged on L type gauge block 3 vertical portion 2, be arranged on second positioning through hole 7 on L type gauge block 3 transverse parts 6, be arranged on the 3rd positioning through hole 4 of vertical portion 2 and transverse part 6 intersections, wherein is combined with first bolt 11, second bolt 12, the 3rd bolt 13 respectively in first positioning through hole 1, second positioning through hole 7, the 3rd positioning through hole 4.
For the corner of protecting workpiece to be machined 16 is not damaged, offer technology groove 5 on the handing-over end between vertical measuring surface 9, the horizontal measuring surface 8.
First positioning through hole 1, second positioning through hole 7 all are oval shape.
The bottom surface 10 of L type gauge block 3 is the measuring basis face.
The utility model high accurate hole is as follows apart from the operation principle of processing position indicator:
By first bolt 11, second bolt 12, the 3rd bolt 13 L type gauge block 3 is fixedly mounted on the table surface of drilling machine earlier; Utilize trigonometric function to calculate first hole 17, second hole 18 of the workpiece 16 actual x that will process, y two direction coordinate figures again; Then workpiece 16 is placed on the table surface, and two datum levels of workpiece 16 are fully contacted with the vertical measuring surface 9 of L type gauge block 3, horizontal measuring surface 8 respectively, any gap can not be arranged, otherwise will influence the pitch-row precision of processing; Use anchor clamps workpiece pressing 16 then, corresponding fluted drill is packed in the drill chuck of drill press spindle into first hole 17 in driller's part 16, after treating that first hole 17 has been bored, unclamp and remove workpiece 16, dispose the smear metal in table surface and the L type gauge block 3, if eliminate endless, will influence the pitch-row precision; After having removed, put into slip gauge 14, slip gauge 15, as shown in Figure 3, the height x2 of slip gauge 14 equal between first hole 17, second hole 18 x to difference x1, the height y2 of slip gauge 15 equal between first hole 17, second hole 18 y to difference y1, and the high base that makes slip gauge 14 fully contact with vertical measuring surface 9, the high base of slip gauge 15 fully contacts with horizontal measuring surface 8, then workpiece 16 is pressed the direction when boring first hole 17, be placed on the table surface, and two datum levels of workpiece 16 are fully contacted with slip gauge 14, slip gauge 15 respectively; Use anchor clamps workpiece pressing 16 again, bore second hole 18.After treating that first hole 17, second hole 18 are finished according to this technology, just can obtain corresponding pitch-row f size.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
