Abstract
The utility model relates to a guide tap and belongs to a tapping tool. A guide pillar is arranged at the front portion of a tap body. The diameter of the guide pillar is identical with that of a bottom hole of a tapped part. Three scrap discharging faces are axially arranged on the guide pillar and evenly distributed. The guide tap solves the defect that a manual tapping tap shakes in cutting. Vertical cutting of the tap in operation is ensured. The guide tap has the advantages of being simple in manufacture, convenient to machine, capable of reducing damage in tap machining and capable of increasing success rate of part machining.
Description
Technical field
The utility model relates to a kind of guide tap, belongs to a kind of tapping tool.
Background technology
Present screw tap mainly partly is comprised of cutting tip and taper shank, and very easy that tap is askew when manual machining screw, therefore in use, the staff will aim the place first, firmly pushes down the screw tap axle center, rotates gently again.When rotating, if firmly uneven, just can not guarantee to be easy to cause screw tap crooked with one heart, so that cutting edge is damaged, cause scrapping of screw tap and processing parts, increased simultaneously operating personnel's work difficulty, reduced operating efficiency.
The utility model content
The purpose of this utility model is will solve the deficiencies in the prior art part and a kind of guide tap is provided, thereby has overcome manual screw tap for tapping pendulous shortcoming in working angles.
The purpose of this utility model is to solve by following technical proposal:
A kind of guide tap, comprise cone, be welded in the centrum afterbody taper shank, open and on cone, go out to cut groove, it is characterized in that: described cone front portion is provided with lead.
The diameter of lead described in the utility model is identical with the diameter of being attacked the part bottom outlet.
Lead described in the utility model has three discharging surfaces vertically, and three discharging surfaces evenly distribute.
Compared to existing technology, the utlity model has following advantage:
1. because the existence of lead is easier to orientation at manual tapping time ratio.
2. lead shape of the present utility model is compared to common cylinder type lead, and easier part with needing tapping matches.
3. compared to common cylinder type lead, the effect that flute has been served as in the space after being clipped by three discharging surfaces is easier to the discharge of cutting swarf.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of screw tap.
The specific embodiment
Below in conjunction with accompanying drawing the utility model solution is described in detail.
As shown in Figure 1, guide tap described in the utility model comprises cone 1, flute 2, lead 3, taper shank 4.Flute 2 leaves in cone 1, and lead 3 is arranged on cone 1 front end, and taper shank 4 is welded in centrum 1 afterbody.The diameter of lead 3 is identical with the root diameter of centrum 1 screw thread, and is identical with the diameter of the bottom outlet of attacking part.Fig. 2 is the left view of screw tap, and as shown in Figure 2, lead 3 radially has three discharging surfaces along centrum 1, and three discharging surfaces evenly distribute.The lead of this shape is compared to cylindrical lead, matches with processing parts easilier.The three discharging surface directions that cut on the opening direction of the flute 2 on the cone 1 and the lead 3 are corresponding, guaranteed that cutting swarf can discharge smoothly.
Claims (3)
1. guide tap, comprise cone, be welded in the centrum afterbody taper shank, open and on cone, go out to cut groove, it is characterized in that: described cone front portion is provided with lead.
2. guide tap according to claim 1, it is characterized in that: the diameter of lead is identical with the diameter of being attacked the part bottom outlet.
3. guide tap according to claim 1, it is characterized in that: lead has three discharging surfaces vertically, and three discharging surfaces evenly distribute.
