Description
Technical field
A kind of engine lathe tapping clamp is the utility model is related to, more particularly to lathe tapping overload protection fixture.
Background technology
In Machining operations, tapping processing, existing common tapping often are carried out to parts using engine lathe
Fixture includes the common parts such as connecting rod, tap holder, screw tap, passage taper shank, sliding sleeve, and screw tap is using rigidity when typically processing operation
Connected mode is fixed in engine lathe tailstock, and such apparatus structure design is not quite reasonable, and technique is complex, is not easy to grasp
Make, particularly in common in-vehicle height of bed rotation speed operation, screw tap breakage phenomena easily occur, screw is smaller, and screw tap broken end probability is got over
Height, higher technical requirements are so proposed not only for operating personnel, and cause processed product defect rate and reprocess
Rate is significantly increased, and wastes production factors, influences production efficiency.
The content of the invention
The purpose of this utility model is to provide a kind of lathe tapping overload protection fixture, solves to deposit in existing process technology
Above-mentioned deficiency, improve operating efficiency.
Realize that the utility model purpose is adopted the technical scheme that：It includes sliding sleeve, overload protecting mechanism and gland spiral shell
Mother, overload protecting mechanism are made up of gripping sleeve, steel ball, spring and hold-down bolt in gripping sleeve outside screw tap, screw tap, clamped in screw tap
Set is arranged in the outer gripping sleeve of screw tap, is arranged with two circular grooves, overload protecting mechanism on gripping sleeve outer wall outside screw tap
In the hole of sliding sleeve one end, outer end is fixed by gland nut, on the sliding sleeve outer wall of installation overload protecting mechanism, is provided with
Two bolt holes corresponding with circular groove on the outer gripping sleeve of screw tap, steel ball are placed in circular groove, and spring is placed on
In bolt hole above steel ball, hold-down bolt is pressed in above spring and is spun in bolt hole；The sliding sleeve other end is provided with passage and bored
Handle mounting hole.
Gripping sleeve is one group of interchangeable serial part in screw tap, comprising replaceable multiple models, gripping sleeve in each screw tap
Outside specification is identical, and the mounting hole that centre is provided with has Multiple Type.
Sliding sleeve is connected with passage taper shank using flat key.
The utility model compared with prior art, has the positive effect that：1st, simple operation, can be on engine lathe
Use；2nd, simple and practical, the tapping range of speeds is adapted to process M6, M8, M10, M12 isotactic on parts in 150Rpm
The screw of lattice；3rd, it is safe and reliable, it in High Speed Threading, can be played a protective role when by strength, effectively avoid screw tap broken end existing
As avoiding the generation of waste product；4th, it is reasonable in design, tapping efficiency high, the operation of feeding adjusting in technical process can be reduced, is improved
Production efficiency, reduce artificial input.
Brief description of the drawings
Accompanying drawing 1 is the utility model use state diagram；Accompanying drawing 2 is sliding sleeve schematic diagram of the present utility model；Accompanying drawing 3 is
The outer gripping sleeve schematic diagram of screw tap of the present utility model.
Embodiment
Below against accompanying drawing, by the description to case study on implementation, specific embodiment of the present utility model is made further
Detailed explanation.
As shown in Figure 1, it includes sliding sleeve 2, overload protecting mechanism and gland nut 5, mistake to the utility model use state
Carry protection mechanism to be made up of gripping sleeve 4, steel ball 7, spring 8 and hold-down bolt 9 in gripping sleeve outside screw tap 3, screw tap, clamped in screw tap
Set 4 is arranged in the outer gripping sleeve 3 of screw tap, is arranged with two circular grooves 12, overload protection on the outer wall of gripping sleeve 3 outside screw tap
Mechanism is arranged in the hole of the one end of sliding sleeve 2, and outer end is fixed by gland nut 5, in the sliding sleeve outer wall of installation overload protecting mechanism
On, provided with two bolt holes 11 corresponding with circular groove 11 on gripping sleeve outside screw tap 3, steel ball 7 is placed on circular groove
In 12, spring 8 is placed in the bolt hole 11 above steel ball 7, and hold-down bolt 9 is pressed in spring 8 and is spun on bolt hole 11 above
It is interior；The other end of sliding sleeve 2 is provided with the passage mounting hole of taper shank 1.
Gripping sleeve 4 is one group of interchangeable serial part in screw tap, comprising replaceable multiple models, and is clamped in each screw tap
The outside specification of set 4 is identical, and the mounting hole that centre is provided with, aperture can unrestricted choice according to the difference of connected screw tap 6.
When the present apparatus works, the moment of torsion of tapping cutting comes from hold-down bolt 9, hold-down bolt 9 active force be delivered to by
In the overload protecting mechanism that gripping sleeve 4, steel ball 7 and spring 8 form in the outer gripping sleeve 3 of screw tap, screw tap.Rotation regulation hold-down bolt
9 change the deformation of spring 8, produce moment of torsion of different sizes to meet the needs of different tapped bores.When screw tap stress is excessive,
Tapping excess load or on earth when, steel ball 7 can depart from the outer contact surface of gripping sleeve 3 of circular groove 12 and screw tap and skid, and then prevent
Screw tap 6 fractures, rate of reducing the number of rejects and seconds.
Application method of the present utility model, comprises the following steps：
1）Being made according to the tapping of parts end-face hole needs, and selects in the sizeable screw tap 6 in aperture, and the screw tap of matching
Gripping sleeve 4, screw tap 6 is inserted in screw tap in gripping sleeve 4, then gripping sleeve in screw tap 4 is installed to outside screw tap in gripping sleeve 3, revolved
Press box nut 5 and compress screw tap 6.
2）Rotatably compress bolt 9 and adjust depth, change the contracted length of spring 8, so as to control steel ball 7 with being clamped outside screw tap
The thrust of set 3, change the torque of the outer gripping sleeve 3 of screw tap, to meet that the screwed hole of different pore size is threaded.
3）Sliding sleeve 2 is enclosed on passage taper shank 1, and flat key 10 is arranged on the key mapping groove on passage taper shank 1, is blocked by flat key 10
Firmly sliding sleeve 2, passage taper shank 1 are arranged on engine lathe, it is ensured that sliding sleeve 2 can not rotate and play slips vertically.
4）The end of passage taper shank 1 is stuck in the mohs tapered bore of engine lathe tailstock, is rotated and specified using lathe chuck
It is threaded that part starts screw thread.
