Abstract
The utility model relates to a portable electric hinge plate for pipe threads, and the utility model is an electric tool used for cutting the pipe threads. A hand hinge plate for the pipe threads used at present is large in labor intensity and low in work efficiency, and a workbench accompanied with a pipe bench clamp is also needed to be matched. The utility model is that a pipe whose threads are needed to be cut is clamped in the hinge plate for the pipe threads, an electric motor is used as power to drive tapping heads on a telescopic hinge plate for the pipe threads to turn around the pipe to cut the pipe threads, and axial stroke of pipe thread cutting is automatically completed. The utility model has the advantages of small size, simple structure and convenient operation. The electromotion of a portable tool for cutting the pipe threads is implemented, labor strength is reduced, work efficiency is enhanced, and no auxiliary tool is needed to be matched.
Description
The utility model relates to a kind of electric tool, is a kind of portable pipe threading plate of the cutting steel pipe screw thread that is used as power with motor.
At present, the cutting tube screw thread uses ministry standard GJB-2(4 usually) W type pipe threading plate, it is to be used as power with manpower, labour intensity is big, inefficiency, and when work also need with the workbench that has the pipe bench vice.
The purpose of this utility model just is at above-mentioned deficiency, and a kind of instrument of the cutting steel pipe screw thread that is used as power with motor is provided.
Novel being achieved in that of this use is equipped with pipe gripper mechanism, sleeve type pipe screw die mechanism, motor and decelerator mechanism in body, by pipe gripper mechanism the tube grip of gas thread to be cut in body, drive telescopic pipe threading plate by motor by decelerator and rotate, cut gas thread around pipe.The structure and the principle of each mechanism below are described respectively.
The pipe gripper structure: mainly contain three fan-shaped brake cam compositions that are contained in a side in the body, three brake cam are mutually 120 ° of distributions, and cam surface has anti-slop serrations, and torsionspring is housed respectively on the camshaft.The pipe of screw thread to be cut is placed between three brake cam, and three cams are by the effect of torsionspring, clamp pipe is directed automatically.
Telescopic pipe threading plate mechanism: two bearings that internal diameter is bigger are housed in body, are fixing the active sleeve that has the gear teeth in the inner ring of two bearings, driving initiatively by motor by decelerator, sleeve rotates.Be equipped with one from moving sleeve in the active sleeve, two sleeves are that helical spline connects, and when being driven rotation from moving sleeve by the active sleeve, also can move vertically in the active sleeve.At a end one cover screw die of detachable replacing is housed, rotates the cutting tube screw thread by drive the pipe of screw die in sleeve from moving sleeve from moving sleeve.Because of two sleeves are that helical spline connects, so, when initiatively the sleeve drive is rotated from moving sleeve, make from moving sleeve and produce an axial thrust load, therefore, driving screw die when pipe rotates the cutting tube screw thread,, finish the axial stroke of cutting tube screw thread according to this by advancing in the active sleeve according to the lead angle of screw die automatically from moving sleeve from moving sleeve.
Motor and decelerator mechanism: motor is fixed on body one side, and driving initiatively by motor by the decelerator in the body, sleeve rotates.In decelerator mechanism manual clutch is housed, purpose is when work, makes electrical motors after rated speed clutch be engaged, and drives pipe threading plate mechanism and rotates, and with this initial moment that increases pipe threading plate, reduces the capacity of motor.
The utility model has following advantage and effect: be power with the motor, drive screw die when pipe rotates the cutting tube screw thread, by moving axially from the lead angle drive screw die of moving sleeve according to screw die, finish the axial stroke of cutting tube screw thread automatically.The utility model volume is little, is easy to carry, simple in structure, easy and simple to handle, has realized the motorized of portable cutting tube threading tool, has alleviated labour intensity, has improved operating efficiency, and has not needed any aid of adapted.
Description of drawings:
Fig. 1 is the utility model structural principle (overlooking) figure.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Below in conjunction with description of drawings the utility model embodiment:
Pipe gripper mechanism: with reference to accompanying drawing, end in body (1) is equipped with three fan-shaped brake cam (9) that are mutually 120 ° of distributions, the convex surface of brake cam (9) has anti-slop serrations, torsionspring (8) is housed on the brake cam axle, the outside of brake cam (9) has the gear teeth, and with cam control panel (7) engagement that has internal tooth, brake cam decenter clutch (21) is equipped with in the outside of control panel (7).Rotate decenter clutch (21), three brake cam (9) are rotated synchronously; Unclamp decenter clutch (21), three brake cam (9) are returned respectively by the effect of torsionspring (8) automatically.
Telescopic pipe threading plate mechanism: with reference to accompanying drawing, two bearings (6) are housed in body (1), the active sleeve (5) that has sprocket wheel is housed in the inner ring of bearing (6), in active sleeve (5), is equipped with, connect for helical spline between two sleeves from moving sleeve (4).When being driven rotation by active sleeve (5), also can in active sleeve (5), move vertically from moving sleeve (4).Have four screw die holes that are mutually 90 ° of distributions at the end from moving sleeve (4), cover four screw die (3) are housed in the screw die hole, screw die (3) is had the control of the cam disc (2) of four cam keys.The gear teeth and bolt die decenter clutch (22) engagement that has the gear teeth are arranged in the outside of cam disc (2), rotate screw die decenter clutch (22) and can drive cam disc (2) rotation.During by dress screw die (3), rotate screw die decenter clutch (22) earlier, driving cam disc (2) rotates, make the cam key of cam disc (2) turn over screw die hole from the moving sleeve (4), four screw die (3) by its order by going into the screw die hole from sleeve (4) interpolation, backward rotation screw die decenter clutch (22) then, four cam keys of cam disc (2) are embedded respectively in the skewed slot of four screw die (3), be rotated further the eccentric wrench (22) of screw die, can control four screw die (3) and move along the direction vertical respectively, control the feed of screw die (3) according to this with the sleeve axial line, withdrawing and cutting output.The travel switch (11) that has a long closed contact is housed in body (1) connects with the power control switch of motor (18); purpose is when driving screw die (3) from moving sleeve (4) and finish the stroke of cutting tube screw thread; by from moving sleeve (4) roof pressure travel switch (11); make its power supply that cuts off motor (18), realize autostop.
Motor and decelerator mechanism: with reference to accompanying drawing, side at body (1) is equipped with single-phase series motor (18) driven gear (17) rotation, gear (17) and gear (16) engagement, side at gear (16) is equipped with thrust bearing (14), opposite side is fixed with initiatively frictional disk (13), end at axle (19) is equipped with driven friction disk (12), driven friction disk (12) is a square tooth splined with axle (19), driven friction disk (12) can move axially in axle (19) upper edge, and be subjected to the effect of spring (15), operated clutch control lever (not drawing among the figure), make driven friction disk (12) do axially-movable, realize the joint of driven friction disk (12) and active frictional disk (13) or separate.Sprocket wheel (20) is housed on axle (19), and sprocket wheel (20) drives initiatively sleeve (5) rotation by chain (not drawing among the figure).
