Description
Technical Field
The utility model belongs to the technical field of screw tap positioning mechanism, especially, relate to a positioning mechanism for processing screw tap.
Background
In the current chinese patent database, disclosed the patent of a screw tap positioner, application number is CN201120456674.4, and application date is 2011.11.17, and the publication number of authorizing is CN202317319U, and the publication date of authorizing is 2012.07.11, and this patent includes the body, is equipped with the dress hole of wearing on the body, and the dress is worn at dress hole front end to the handle of screw tap, is equipped with the location structure of circumference location screw tap between body and the screw tap, wear to be equipped with the elastic device that promotes the screw tap after the pressurized and outwards move along dress hole axial in the dress hole, its weak point lies in: when the device is used for clamping and machining the screw tap, one section of the screw tap is suspended in the air, the screw tap is subjected to larger tangential force and is easy to break, and the machining precision is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that current screw tap positioner has the location incomplete, and adds man-hour, and the processingequipment clamping can produce wearing and tearing to screw tap body on the screw tap body itself, in order to improve its weak point, the utility model provides a positioning mechanism for processing screw tap.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
the utility model provides a positioning mechanism for processing screw tap, is including the column body, and the spacing hole of scarf joint screw tap stalk portion is seted up to column body one end, and the round hole that holds screw tap working part is seted up to the other end, spacing hole, round hole and the coaxial setting of column body center pin, spacing hole and round hole switch-on are located the column body that the round hole corresponds and have been seted up a plurality of axial open slots, the open slot is used for the awl tooth of scarf joint screw tap working part, and each open slot evenly sets up on the circumferencial direction that uses column body center pin as the center.
The utility model discloses the during operation, the screw tap stalk portion that will wait to process the screw tap is embedded into the spacing downthehole of columnar body, and the awl tooth part that will wait to process the screw tap simultaneously along the open slot direction scarf joint on the columnar body in the columnar body, waits to process the screw tap whole and just fixes a position completely in the columnar body this moment, and the external diameter of waiting to process screw tap awl tooth department is greater than the external diameter of columnar body.
Compared with the prior art, the beneficial effects of the utility model are that: because the setting of spacing hole and open slot in the column for wait to process the screw tap and can stabilize and have the location of direction, the setting of column body has avoided the clamping instrument direct and wait to process the contact of screw tap outer wall simultaneously, prevents to wait that the outer wall of processing the screw tap from producing wearing and tearing because of the clamping is out of position, and the column body is connected with the screw tap and becomes a whole, and intensity is high, and the device is applicable to in the industrial production, has very strong practicality.
Be equipped with the spacing of laminating with peripheral hardware screw tap chip guide groove on the round hole inner wall between the adjacent open slot, spacing cross section is oval form, and an arcwall face laminates with the round hole inner wall, and another arcwall face laminates with peripheral hardware screw tap chip guide groove. The gap between the chip groove of the screw tap to be processed and the cylindrical round hole is filled due to the arrangement of the limiting strips, the screw tap to be processed is more stable, and the processing precision is improved.
The surface of the columnar body is provided with anti-skid grains convenient for clamping. The anti-slip lines are arranged so that the cylindrical body is more stable during clamping.
The open slot is provided with three.
