One, technical field
The present invention relates to a kind of motor-driven tapping clamp, relate in particular to a kind of clamping screw tap that can be reliable, stable, can add man-hour at clamping screw tap again, there is the motor-driven tapping clamp of the function of overload protection and fast return.
Two, background technology
At present, in machining, often can on the equipment such as bench drill, radial drilling machine and drilling and milling machine, utilize conventional clip clamping screw tap to carry out the processing of the following minor diameter internal thread of M10, and carry out the above-mentioned following phenomenon of easy generation in man-hour that adds;
, once run in material hard spot or the larger situation of tapping surplus, easily there is the problems such as rotten tooth or screw tap fracture in the first phenomenon: for the screw tap below M10, intensity own is just not enough;
The second phenomenon: carry out in the situation of blind hole tapping, as can not be in time screw tap return time, just there will be the problems such as screw tap fractures.
The third phenomenon: current existing machine returns after tapping with tapping method, and speed is slower, and production efficiency is lower.
The 4th kind of phenomenon: when utilizing conventional clip clamping screw tap, particularly nominal diameter is slightly bigger, if in the situation that clamping not tight is prone to and skids, cannot normally complete like this processing of screw thread.
The 5th kind of phenomenon: also can utilize cubic sleeve clamping screw tap to overcome skidding in actual production and occur, but the size of the tetragonal body of the screw tap retained part of different size also can be different in the ordinary course of things, the cubic sleeve that so just need to change different size clamps, and efficiency is lower.
Three, summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of clamping screw tap that can be reliable, stable is provided, can add man-hour at clamping screw tap again, there is the motor-driven tapping clamp of overload protection and fast return function.
The technical solution adopted for the present invention to solve the technical problems is: a kind of motor-driven tapping clamp, Morse taper shank connects upper cover, upper cover is provided with upper cover locking nut, axle is installed in upper cover, axle middle part is provided with center lateral pin, on axle, cover has spring, friction plate is installed on spring, mounting block block on friction plate, copper washer is installed on stopper seat, block gear is installed on copper washer, block gear connects pinion, pinion seat is installed on pinion, little wheel shaft is installed in pinion, pinion connects internal gear, lower cover is installed on internal gear, lower cover and upper cover are installed in the enclosure, shell middle part is provided with hold-down screw, pinion seat outer wall is installed pin, pinion seat inwall connects copper sheathing, copper sheathing inwall connecting axle, axle top installing drill chuck.
The invention has the beneficial effects as follows; clamping screw tap that can be reliable, stable, can add man-hour at clamping screw tap again, has the function of overload protection and fast return; not only can on bench drill, radial drilling machine and drilling and milling machine, use, also can on lathe, use simultaneously.The present invention can enhance productivity, and reduces production costs, and guarantees Tapping Quality, alleviates operating personnel's labour intensity.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, further illustrate the structure and characteristics of the motor-driven tapping clamp of the present invention, in accompanying drawing:
Fig. 1 is the structure chart of embodiments of the invention one.
In figure: 1. Morse taper shank, 2. spring, 3. friction plate, 4. hold-down screw, 5. internal gear, 6. lower cover, 7. little wheel shaft, 8. axle, 9. drill chuck, 10. copper sheathing, 11. pinion seats, 12. pins, 13. block gears, 14. pinions, 15. copper washers, 16. stopper seats, 17. shells, 18. upper cover locking nut ，19. center lateral pins, 20. upper covers.
Five, the specific embodiment
In the embodiment shown in fig. 1, be provided with Morse taper shank (1), spring (2), friction plate (3), hold-down screw (4), internal gear (5), lower cover (6), little wheel shaft (7), axle (8), drill chuck (9), copper sheathing (10), pinion seat (11), pin (12), block gear (13), pinion (14), copper washer (15), stopper seat (16), shell (17), upper cover locking nut (18), center lateral pin (19), upper cover (20).
Implement motor-driven tapping clamp of the present invention, comprise Morse taper shank (1), it is characterized in that, at described Morse taper shank (1), connect upper cover (20), upper cover (20) is provided with upper cover locking nut (18), axle (8) is installed in upper cover (20), axle (8) middle part is provided with center lateral pin (19), the upper cover of axle (8) has spring (2), friction plate (3) is installed on spring (2), the upper mounting block block (16) of friction plate (3), the upper copper washer (15) of installing of stopper seat (16), the upper block gear (13) of installing of copper washer (15), block gear (13) connects pinion (14), the upper pinion seat (11) of installing of pinion (14), little wheel shaft (7) is installed in pinion (14), pinion (14) connects internal gear (5), the upper lower cover (6) of installing of internal gear (5), lower cover (6) and upper cover (20) are arranged in shell (17), shell (17) middle part is provided with hold-down screw (4), pinion seat (11) outer wall is installed pin (12), pinion seat (11) inwall connects copper sheathing (10), copper sheathing (10) inwall connecting axle (8), axle (8) top installing drill chuck (9).
Implement motor-driven tapping clamp of the present invention, this fixture is comprised of three parts: top is safeties, with upper cover (20), by actual conditions, regulate after tapping moment of torsion, just use cover locking nut (18) locking, when screw tap is attacked on earth or broken down, when moment of torsion is excessive, friction plate skids, screw tap does not turn, and guarantees that screw tap is unlikely to fracture.
Middle part is running part, in fixture shell (17), there is internal gear (5) to rotate with drill press spindle, because pinion seat (11) is blocked and do not turn by pin (12), pinion just plays gap bridge effect, makes block gear (13) opposite spin.When tapping, fixture is to pressing down, and spring (2) compression is blocked little axle (8) Shang center lateral pin (19) on fixture top block gear (7), little axle (8) and the synchronized rotation of drill press spindle, and during tapping, gear dallies always.Attack predetermined needs after the depth of thread, when operator mentions drill press spindle sleeve, spring (2) just unclamps, little axle (8) is moved down, make center lateral pin (19) throw off above stopper seat (16) and block with block gear (13), little axle (8) reverses immediately, and screw tap just automatically exits from workpiece hole.Because internal gear (5) is 40 teeth, block gear is 20 teeth, so screw tap is fast again while exiting than tapping.
Bottom is clamping screw tap part, utilizes the drill chuck after an improvement to clamp screw tap, can clamping M4-M10 etc. screw tap, adjust tapping moment of torsion, can carry out tapping.No matter be after through hole tapping or blind hole tapping occur that rotten tooth or screw tap fracture, under the prerequisite that does not simultaneously have to be strict with in double thread hole site, although can repair rotten tooth hole by other modes such as electric welding or electric discharges, broken tap also can be by adopting special purpose device to be taken out, or chosen position carries out tapping more separately, can reduce like this production efficiency, increase production cost.The screwed hole of processing when needs has in the situation of strict status requirement, and above-mentioned method for repairing and mending just cannot be used, and the crudy of screwed hole is just difficult to guarantee.
Implement the present invention, effect is fine.
