Description
Technical field
The utility model belongs to screw thread cutting device field, is specifically related to a kind of manual screw thread cutting device.
Technical background
In the processing of small lot component of machine, often to adopt hand tapping, used instrument is tap wrench, monkey wrench etc.Carry out tapping with these tool holding screw taps.This method of operating requires the operator must have higher professional technique, the good technical essential of GPRS during operation, and the perpendicularity of screw tap guarantees with estimating entirely during tapping.Defective is the quality that be difficult to guarantee tapping, and in the tapping engineering since tapping not just, firmly inhomogeneous, be easy to the screw tap that fractures, cause scrapping of part.For overcoming above-mentioned drawback, people have invented double hand tapping machine.For example notification number is that the utility model patent of 2049979U promptly discloses a kind of " hand tapping machine ".This tapping machine comprises base, column, leading screw etc., and screw tap is installed in the lower end of leading screw.Must rotate and press down leading screw during tapping drives screw tap rotation and moves down.Artificially firmly inhomogeneous when shortcoming is tapping, screw tap easily fractures.
The utility model content
For addressing the above problem, the utility model provides a kind of double hand tapping machine, and this tapping machine firmly evenly, can improve the tapping quality when tapping.
The technical scheme that its technical problem that solves the utility model adopts is: design a kind of double hand tapping machine, comprise base and column, it is characterized in that connecting on the column cantilever, one end of the cantilever empty capsid that is fixedly connected, place elastomeric sleeve in the empty capsid, elastomeric sleeve is a split-type structural, connect spring between the outer wall of elastomeric sleeve and the empty capsid inwall, penetrate leading screw in the elastomeric sleeve, suit sliding nut on the leading screw, elastomeric sleeve tightly is stuck on the sliding nut, the lower end connecting filament tapered sleeve of leading screw.
The utility model connects handwheel in the upper end of leading screw.Suit slip cap on the column is offered screwed hole on the slip cap, screw in trip bolt in the screwed hole, fixes two cantilevers on the slip cap, the end of each the root cantilever empty capsid that is fixedly connected.
The utlity model has following beneficial effect:
1. owing to change tapping by the rotating band movable wire coning of leading screw, thereby the movement velocity of screw tap is even, and the application of force during tapping is also even, has guaranteed the tapping quality, dependable performance;
2. the free centering in the time of can realizing tapping automatically increases pressure during tapping, promote leading screw when screw tap withdraws from automatically, and the gravity of having eliminated leading screw is to institute's tapping, particularly than the minor thread and the damage that may cause than the screw thread of softwood matter;
3. the control tapping degree of depth that can be convenient, flexible;
4. applied range is specially adapted to the tapping processing of the parts of blind hole, steel part, frock, mould and small lot batch manufacture.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A structural representation of Fig. 1;
1. cantilevers among the figure, 2. trip bolt, 3. slip cap, 4. handwheel, 5. empty capsid 6. elastomeric sleeves 7. springs 8. sliding nuts, 9. leading screw, 10. wire taper sleeve, 11. screw taps, 12. bases, 13. columns, 14. locating rings, 15. fastening bolts.
The specific embodiment
As shown in Figure 1: on base 12, erect a column 13, suit slip cap 3 on the column 13, slip cap 3 is offered screwed hole, screws in trip bolt 2 in the screwed hole.Fix two cantilevers 1 on the slip cap 3, the end of each the root cantilever empty capsid 5 that is fixedly connected.Place elastomeric sleeves 6 in the empty capsid 5, elastomeric sleeve 6 is the two halves split-type structural, connects spring 7 between the outer wall of elastomeric sleeve 6 and empty capsid 5 inwalls.Penetrate leading screw 9 in the elastomeric sleeve 6, suit sliding nut 8 on the leading screw 9, elastomeric sleeve 6 tightly is stuck on the sliding nut 8.The lower end connecting filament tapered sleeve 10 of leading screw 9, the screw tap 11 of packing in the wire taper sleeve 10.The upper end of leading screw connects handwheel 4.
Before the tapping, be placed on workpiece on the base 12 or clamping is placed on the base 12 after on the flat-nose pliers again, work piece positioning is held.Unclamp trip bolt 2, slip cap 3 is moved up and down along column 13 regulate height and position, tighten trip bolt 2.Then locating ring 14 is moved to below the slip cap 3, screw locating ring fastening bolt 15.The fixed-site of slip cap 3 and cantilever 1.Rotate handwheel 4, leading screw 9 rotations move down, and begin tapping after the screw tap 11 of leading screw 9 lower ends touches workpiece.Because leading screw 9 is good with the perpendicularity of base 12, guaranteed the perpendicularity of tapping, when tapping, just fundamentally solved traditional just attacking not up hill and dale like this with the tap wrench tapping, firmly inhomogeneous, the problem of frangibility screw tap has improved the tapping quality.
Can unclamp trip bolt 2 during tapping, cantilever 1 can freely rotate as required and adjust the position like this.In addition, also workpiece directly can be pressed on the base 12, compress for making things convenient for the workpiece location, many screwed holes that distribute on base 12 get final product Work-sheet pressing with bolt.
When using the tapping of this tapping machine because the pitch of sliding nut 8, leading screw 9 and screw tap 11 is often different, thereby must solve the pitch difference and cause can't the tapping phenomenon.The utility model is owing to adopted the elastomeric sleeve 6 of two halves split-type structurals, and elastomeric sleeve 6 is pressed on the sliding nut 8 by the elastic force of spring 7.During tapping, leading screw 9 rotates and moves down with screw tap 11, and sliding nut 8 can move up along elastomeric sleeve 6, and the speed that moves is according to the different free adjustment of pitch.Played the effect of regulating the displacement size of leading screw 9 at this, made leading screw 9 can follow and adjust displacement, eliminated the pitch difference caused problem of screw tap 11 with leading screw 9 according to the pitch of screw tap 11.In tapping process; elastomeric sleeve 6 moves up and applies downward power to leading screw; promptly when tapping, increased tapping power; and tapping is when withdrawing from after finishing; elastomeric sleeve 6 moves down and applies lifting force upwards to leading screw; thereby having reduced that screw tap withdraws from is the pressure of double thread, has protected screw thread.
The utility model adopts the advantage of two cover tapper mechanisms to be: reduced the replacement frequency of screw tap, increased work efficiency.
