Abstract
The utility model discloses hexagonal frock in a kind of punching of miniature screw head, it is mainly used in manufacture process, need to produce hexagonal in special non-standard screw punching, including workbench according to assembling demand, the working face of the workbench offers the positioning hole that positioning is processed screw.Accurate positioning is rapid, high in machining efficiency when the utility model is processed；Clamping process will not cause to damage to screw thread；Punching tool is guided with pilot hole, avoids punching tool stress run-off the straight during processing from causing the interior hexagonal depth out of plumb processed.
Description
Technical field
Part manufacture field is the utility model is related to, more particularly to hexagonal frock in a kind of punching of miniature screw head.
Background technology
In manufacture process, generally require to prepare some special screws according to assembling demand, but this extraordinary spiral shell
Silk can not effectively be processed using national standard production equipment, and a kind of production work of new special screw must be developed for meet demand
Dress.Existing process technology is to carry out positioning clamping to workpiece with vice, and when clamping force is excessive, workpiece external screw thread can be broken
Bad, part, which produces, to be scrapped；If clamping force is small, workpiece stress can move during processing so that workpiece is difficult to meet size, outer after processing
The all requirements such as shape, form and position tolerance, roughness；Furthermore because part comparison is small, positioning, clamp, processing all inconveniences, production
Efficiency is low.
The disclosure of background above technology contents is only used for auxiliary and understands design of the present utility model and technical scheme, and it is not
The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application in no tangible proof
In the case of disclosed, above-mentioned background technology should not be taken to evaluate the novelty and creativeness of the application.
Utility model content
The utility model purpose is to propose hexagonal frock in a kind of miniature screw head punching, to solve above-mentioned prior art
Existing positioning, clamp, processing inconvenience, the technical problem of low production efficiency.
Therefore, when being processed the utility model proposes one kind can quick and precisely positioning and clamping, improve machining accuracy and production
Efficiency rushes interior hexagonal frock.
Preferably, the utility model can also have following technical characteristic：
Hexagonal frock in a kind of miniature screw head punching, including workbench, the working face of the workbench open up
There is the positioning hole that clamping and positioning is processed screw.
Further, the positioning hole is screw；The screw matches with processed screw thread.
Further, in addition to guide sleeve, the guide sleeve are in funnel-shaped structure；The guide sleeve lower surface and the work
Make the working face fitting of platform；Pilot hole is offered on the central axis of the guide sleeve.
Further, the central axis of the guide sleeve overlaps with processed screw center line axis；The pilot hole runs through
Upper and lower two end faces of guide sleeve；The pilot hole internal diameter, which is slightly larger than, is processed screw head external diameter.
Further, in addition to some alignment pins, the working face of the workbench be further opened with several with it is described
First dowel hole of alignment pin matching, the guide sleeve bottom offer several corresponding with first dowel hole the
Two dowel holes.
Further, the length of the alignment pin is more than the depth of first dowel hole, and the alignment pin is stretched
The length for going out first dowel hole is less than the depth of the second dowel hole.
The beneficial effect that the utility model is compared with the prior art includes：1) accurate positioning is fast when the utility model is processed
It is fast, high in machining efficiency；2) clamping process will not cause to damage to screw thread；3) punching tool is guided with pilot hole, when avoiding processing
Punching tool stress run-off the straight causes the interior hexagonal depth out of plumb processed.
Brief description of the drawings

Fig. 2 is the utility model top view.
Fig. 3 is the utility model guide sleeve structure schematic diagram.
Fig. 4 is utility model works platform structure schematic diagram.
Fig. 5 is the utility model alignment pin stereogram.
Embodiment
With reference to embodiment and compare accompanying drawing the utility model is described in further detail.It should be emphasized that
It is, what the description below was merely exemplary, rather than in order to limit the scope of the utility model and its application.
With reference to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical reference represents
Identical part, unless stated otherwise.
Hexagonal frock in a kind of miniature screw head punching, including workbench 3, the working face of the workbench 3 are opened
The positioning screw hole 2 of screw is processed provided with positioning, and the positioning screw hole 2 matches with processed screw thread, can be according to difference
The positioning screw hole 2 that the size selection of screw thread matches.
Preferably, in addition to guide sleeve 1, the guide sleeve 1 is in funnel-shaped structure, the lower surface of guide sleeve 1 with it is described
The working face fitting of workbench 1；Pilot hole is offered on the central axis of the guide sleeve 1.The central axis of guide sleeve
Overlapped with processed screw center line axis, pilot hole runs through described 1 upper and lower two end face of guide sleeve；The pilot hole internal diameter omits
More than processed screw head external diameter, if in this punching hexagonal frock process be grub screw, pilot hole internal diameter is slightly larger than
The maximum gauge of positioning screw hole 2；If what hexagonal frock was processed in this punching is to have head screw, pilot hole internal diameter has slightly larger than this
Head screw head maximum outside diameter.Preferably way is：The tool body upper part that rushes of processing used is cylinder, and lower end is hexagonal in punching
Punch-pin head, and the cylinder diameter for rushing tool top matches with pilot hole internal diameter, keeps pilot hole, punching tool, is processed screw three
The central axis of person is in coincidence status as far as possible.Punching tool is guided with pilot hole, avoids punching tool stress run-off the straight during processing from causing
The interior hexagonal depth out of plumb processed.
The working face of the workbench 3 is further opened with several the first dowel holes matched with the alignment pin 5
4, the guide sleeve bottom offers several second dowel holes 41 corresponding with first dowel hole 4.The positioning
The length of pin 5 is more than the depth of first dowel hole 4, and the alignment pin 5 stretches out the length of first dowel hole 4
Depth of the degree less than the second dowel hole 41.
It would be recognized by those skilled in the art that it is possible that numerous accommodations are made to above description, so embodiment and attached
Figure is intended merely to describe one or more particular implementations.
It is counted as example embodiment of the present utility model although having been described above and describing, those skilled in the art will be bright
