Abstract
The utility model discloses a kind of hole drilling dies for the processing of helical-lobe compressor top board, multiple holes including disc-shaped body and setting on the body, it is characterised in that: the chip space that one end of the disc-shaped body is equipped with convenient for chip removal.The utility model on mold by being arranged chip space, make that there is certain clearance space between hole drilling die and workpieces processing, to make the chip drilled out largely can be successfully discharged by chip space, chip is not to be repeatedly lifted up middle extraction from drill bit, both processing efficiency can be improved, also improve the service life of drilling tool, and the mold of this utility model also very easily carries out circumferentially positioned, and processing efficiency is enable further to be promoted.
Description
Technical field:
The utility model relates to molds, the more particularly, to hole drilling die of helical-lobe compressor top board processing.
Background technique:
Pressing plate on helical-lobe compressor has porous, and size is larger, and solid capacity is big when processing.Hole adds on existing pressing plate
Work adopts drill jig, which is placed on workpiece planarization, and the chip drilled out can only be taken out of by drill bit.At the lesser hole of drill straight diameter,
Chip removal is extremely unsmooth, and when drilling need to be repeatedly lifted up drill bit constantly to take chip out of, on the one hand influences processing efficiency, on the other hand also
Cutter life；In addition, existing drill jig keeps concentric circumferentially positioned also inconvenience with workpiece, working efficiency is also affected.
Summary of the invention:
It is proposed the purpose of the utility model is to overcome the deficiency of the above-mentioned prior art a kind of for helical-lobe compressor
The hole drilling die of pressing plate processing, its technical solution is as follows:
The hole drilling die, multiple holes including disc-shaped body and setting on the body, and the one of disc-shaped body
End setting chip space.
Further, the chip space is open type annular groove.
Further, the groove depth 4-6mm of the open type annular groove.
Further, one end of the disc-shaped body is equipped with first shaft shoulder；The open type annular groove is by first shaft shoulder
Circumference side and the end face of disc shape body corresponding end are constituted.
Further, the end of first shaft shoulder, which is equipped with, is used for the second circumferentially positioned shaft shoulder.
Further, second shaft shoulder diameter is adapted with the aperture of the centre bore on pressing plate workpiece, the drilling die
Tool is positioned on pressing plate workpiece by the centre bore on the second shaft shoulder grafting pressing plate workpiece.
Further, the Kong Xiangshi to be processed in the distribution in multiple holes in the disc-shaped body and pressing plate workpiece
Match.
The utility model is made between having centainly between hole drilling die and workpieces processing by the way that chip space is arranged on mold
Gap space, so that the chip drilled out be made largely successfully to be discharged by chip space, chip is not from being repeatedly lifted up of drill bit
It draws, processing efficiency both can be improved, also improve the service life of drilling tool, and the mold of this utility model is also very convenient
Ground progress is circumferentially positioned, and processing efficiency is enable further to be promoted.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
The utility model is further described with reference to the accompanying drawings and embodiments.
The hole drilling die of the utility model is used for the hole machined to helical-lobe compressor top board, such as Fig. 1, the hole drilling die packet
It includes: the multiple holes 11 of disc-shaped body 1 and setting on the body, and it is convenient for the chip removal of chip removal in the setting of one end of disc-shaped body
Slot 12, in order to which the metal fillings for the generation that drills quickly discharges.
The chip space 12 of the present embodiment is open type annular groove, which is by being arranged in disc-shaped body 1 one
What first shaft shoulder 13 at end was realized, it is made of, is formed the circumference side of first shaft shoulder 13 and the end face of 1 corresponding end of disc-shaped body
The chip space of one circular ring shape.The axial length of first shaft shoulder constitutes the groove depth of open type annular groove, groove depth 4-6mm.
In order to facilitate the circumferentially positioned of hole drilling die, the hole drilling die of the utility model is also provided with second shaft shoulder 14, should
The end of 13 shoulder of first axle, and existing centre bore on the outer diameter of second shaft shoulder 14 and pressing plate workpiece 2 is arranged in second shaft shoulder 14
Diameter is adapted, in this way when carrying out hole machined to pressing plate workpiece 2, as long as second shaft shoulder on the drilling die of the utility model is inserted
In centre bore 21 on 14 grafting pressing plate workpiece, so that it may carry out quick week using the pressing plate workpiece 2 being located in clamping mold
Positioning.
In order to keep hole drilling die and corresponding mechanism more succinct, the hole drilling die of the present embodiment is rotated with workpiece, that is, works as pressure
On plate workpiece 2 after the completion of the hole machined of a radial position, when need to process the hole in another radial position, workpiece turns with respect to drilling tool
Dynamic, hole drilling die is rotated with workpiece at this time, therefore the institute on the distribution in multiple holes 11 in disc-shaped body 1 and pressing plate workpiece 2
The hole to be processed is adapted.
