Abstract
It the utility model is related to a kind of frock for the numerical control borer hand tapping for ensureing hole processing quality requirement, the shank body being assembled together including top body, with top body, one end of top body is top, and the other end is internal thread hole, and handle is welded with one end of the internal thread hole of top body is cylindrical；One end of shank body is installed on by its external screw thread in the internal thread hole of top body, the other end of shank body is No. 4 taper shanks of Mohs, acted on using screw thread rotation feeding, apply certain pressure to the screw tap afterbody for carrying out screw thread process, and it is always maintained in whole process, screw tap is set to keep plumbness with machine direction all the time during whole screw thread process, prevent screw tap crooked and fracture, it is preferable to process rear thread surface quality, machining accuracy has reached drawing requirement, avoids the quality problems of threaded hole dimension overproof.
Description
Technical field
It the utility model is related to hole processing field, more particularly to a kind of numerical control for ensureing hole processing quality requirement
The frock of boring machine hand tapping.
Background technology
In the product processing of numerical control borer, the processing of threaded hole can be all run into.In general, larger-diameter screw thread
Processed using screw cutter, less screw thread is processed using molding thread tap.When common boring machine is processed, main shaft top is used
The centre bore of screw tap afterbody is lived on pinnacle, and swivel feeding handle holds out against screw tap afterbody while the process of screw tap rotation tapping, and one
Appropriate pressure is directly kept, screw tap uniform force in tapping process can be made, avoid threaded hole crooked, ensure threaded hole
Processing quality requirement.
Numerical control device developed rapidly in recent years, and most equipment realizes the renewal of numerical control device.Boring machine is even more to realize
Full-numerical-control is processed.But it have been found that in the process using tap tapping, the control of numerical control program and the swivel feeding of screw tap
Matching has some setbacks.For example be very easy to realize on common boring machine keeps appropriate in screw tap afterbody using feeding handle and holds out against
The operation of power, on numerical control borer just it is extremely difficult, can only crawl main shaft microfeed, operating personnel cannot get pressure it is anti-
Feedback, is unable to control the size of pressure.During screw tap rotates tapping, spindle top and screw tap afterbody are without the common boring of the image of Buddha
Bed effectively coordinates like that.It is top screw tap to be followed to feed when axis feeding is excessively slow, separate with screw tap afterbody, can be made in processing
Crooked into screw tap, there are quality problems in threaded hole；It is top excessive with the pressure of screw tap afterbody when axis feeding is too fast, can be straight
Connect and cause the damage of screw tap blade to cause the rotten tooth of screw thread, screw tap can directly fracture sometimes.Now need combine common boring machine manually into
To the characteristics of, redesign on numerical control borer utilize hand feed carry out hole processing frock.
The content of the invention
There is provided one kind the purpose of the utility model is to overcome above-mentioned deficiency of the prior art utilizes hand feed to carry out
The frock of the numerical control borer hand tapping of hole processing.
What the technical solution of the utility model was realized in：A kind of frock of numerical control borer hand tapping, including it is top
Body, the shank body being assembled together with top body, one end of top body is top, and the other end is internal thread hole, in top body
Handle is welded with one end of threaded hole is cylindrical；One end of shank body is installed on by its external screw thread in the internal thread hole of top body, handle
The other end of body is No. 4 taper shanks of Mohs.
The top of described top body one end is that surface is top by 60 ° quenched, and the internal thread hole of the top body other end is
The internal thread hole of M48 × 2.
Four, the handle point, is symmetrically and evenly welded on top external circle.
The external screw thread of one end of shank body is the external screw thread of M48 × 2.
The good effect that the technical solution of the utility model produces is as follows：Acted on using the screw thread rotation feeding of M48 × 2,
Apply certain pressure to carrying out the screw tap afterbody of screw thread process, and be always maintained in whole process, make silk
Cone keeps plumbness with machine direction all the time during whole screw thread process, it is therefore prevented that screw tap is crooked and fractures, after processing
Thread surface quality is preferable, and machining accuracy has reached drawing requirement, avoids the quality problems of threaded hole dimension overproof.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the use state diagram of the utility model.
Embodiment
As shown in Figure 1, a kind of frock of numerical control borer hand tapping, including top body 1, it is assembled together with top body
Shank body 2, one end of top body 1 is top, and the other end is internal thread hole 4, is welded on one end of the internal thread hole of top body 1 is cylindrical
There is handle 3；One end of shank body 2 is installed on by its external screw thread in the internal thread hole 4 of top body, and the other end of shank body 2 is Mohs 4
Number taper shank.
Top 60 ° of top, internal thread holes 4 of top 1 other end of body for passing through quenching for surface of described 1 one end of top body
For the internal thread hole of M48 × 2.
The handle 3 divides four, is symmetrically and evenly welded on top external circle.
The external screw thread of one end of shank body 2 is the external screw thread of M48 × 2.
The top external footpath of the frock is φ 70, and one end is top for 60 ° of surface by quenching, and the other end is in M48 × 2
Threaded hole, close to threaded hole one end it is cylindrical on be welded with 4 handles.Shank body one end is No. 4 taper shanks of Mohs, and the other end is M48 × 2
External screw thread.The external screw thread of M48 × 2 is common angular thread, and angle of thread is 60 degree, major diameter 48mm, pitch 2mm, and path is
45.9mm。
First the internal and external threads of top body 1 and the M48 of shank body 2 × 2 are assembled together during use, then by the Mohs 4 of shank body 2
Number taper shank is assembled on numerical control borer main shaft 9, and main shaft 9 and frock are moved to Working position.Screw tap 6 is placed on adding for workpiece 8
The oral area of the good thread Pilot hole 7 of work, rotational handle 3, makes the top centre bore for heading into 6 afterbody of screw tap in frock and keeps suitable
When pressure.Screw tap 6 is rotated using screw tap bracket 5 and starts tapping, while the handle 3 of rotary tooling, makes top one in frock
Directly keep certain pressure.Handle 2 is inverted after the completion of screw thread process, top body 1 departs from screw tap 6, uses screw tap bracket 5
Screw tap 6 is exited, removes frock, is machined.
