Abstract
The utility model provides a hand tapping device which comprises a fixed seat, a guiding sleeve, a tapping frame and a screw die. An installation head where the screw die is arranged is arranged in the middle of a lower layer of the tapping frame, an annular slide rail is designed at the lower portion of the installation head, an annular railway vertically penetrating through the guiding sleeve is designed in the middle of the guiding sleeve, the slide rail is in a vertical slide fit with the annular railway, and a cylindrical stripe portion of a part to be tapped penetrates through the slide rail to extend into the screw die. The hand tapping device can rotate the tapping frame to drive the screw die to tap the cylindrical stripe portion. The device can finish location in tapping through the guiding sleeve and the slide rail of the tapping frame. Thus, the device is more accurate in location and higher in thread processing quality. Meanwhile, a hand wheel structure of the tapping frame is utilized to finish rotation, so that the device is quicker and more convenient in rotation and higher in efficiency.
Description
Technical field
The utility model relates to hardware & tools spanner technical field, is specifically related to a kind of Manual tapping device.
Background technology
The process of making screw thread is called tapping, the tapping of standard component is generally completed by large-scale tapping machine, processing for screw thread on those nonstandard parts, the manual tapping of many employings completes, according to manufacturing also externally threaded difference of internal thread, select different chasing bars to complete, the tapping of internal thread completes with screw tap conventionally, and externally threaded tapping completes with screw die conventionally.The die handle that screw die generally has symmetrical stationary roll by both sides fixes, and during use, the age of a draught animal of screw die is put on the steel bar of tapping, by the die handle of screw die, to pull screw die rotation and just can on steel bar, process external screw thread.Use screw die to add man-hour requirement and the middle axial direction of screw die is guaranteed coaxial with steel bar, by hand during tapping, people need to watching by eyes, then by ceaselessly adjusting die handle, realize the centering of the two, operating difficulties, inefficiency, tapping effect is poor.
Utility model content
For above problem, the utility model provides a kind of use manual mode, and contraposition is accurate, and tapping is Manual tapping device easily.
The utility model solves the technical scheme that its technical problem adopts: this Manual tapping device comprises holder, fairlead, tapping frame, screw die; Described tapping is set up two-layer in respect of what be fixedly connected with, and upper strata is hand wheel structure, and the centre of lower floor is for installing the mounting head of described screw die; The bottom of described mounting head is designed with annular slip rail, described fairlead is fixed on the top of described holder, the centre of fairlead is designed with the circular orbit of up/down perforation, the relatively described circular orbit of described slip rail slides up and down assembling, treats that the cylindrical bars of tapping part partly gos deep in described screw die through described slip rail.
As preferably, the lower floor of described tapping frame is engraved structure.
As preferably, described holder is designed to three and grabs chuck structure, and its underpart is designed with bits hole.
The beneficial effects of the utility model are: this Manual tapping device is mainly used to the external screw thread of processing parts, add man-hour, people use described holder to treat the cylindrical bars partial fixing of tapping part, and by cylindrical bars part by described screw die together with described tapping frame jack-up; By rotating described tapping frame, just can drive screw die partly to complete tapping to described cylindrical bars.Location when the slip rail of this device by fairlead and described tapping frame completes tapping, it is more accurate to locate, and screw processing quality is higher.Use the hand wheel structure of tapping frame to complete spinning movement simultaneously, rotate more fast and easy, efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of this Manual tapping device.
The specific embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in embodiment in Fig. 1, this Manual tapping device, it comprises holder 1, fairlead 2, tapping frame 3, screw die 4; Described tapping frame 3 is designed be fixedly connected with two-layer, and upper strata is hand wheel structure, and the axial component of hand wheel structure is designed with through-hole structure.The centre of tapping frame 3 lower floors is for installing the mounting head 31 of described screw die 4; Between described screw die 4 and mounting head 31, be detachable installation, people can complete the externally threaded processing of difference by changing different screw die 4.The bottom of described mounting head 31 is designed with annular slip rail 32, described fairlead 2 is fixed on the top of described holder 1, the centre of fairlead 2 is designed with the circular orbit of up/down perforation, the relatively described circular orbit of described slip rail 32 slides up and down assembling, treats that the cylindrical bars part 5 of tapping part is goed deep in described screw die 4 through described slip rail 32.
This Manual tapping device is mainly used to the external screw thread of processing parts, adds man-hour, and people use described holder 1 that the cylindrical bars part 5 for the treatment of tapping part is fixing, and by cylindrical bars part 5 by described screw die 4 together with described tapping frame 3 jack-up; By rotating described tapping frame 3, just can drive 4 pairs of described cylindrical bars parts 5 of screw die to complete tapping.Location when the slip rail 32 of this device by fairlead 2 and described tapping frame 3 completes tapping, it is more accurate to locate, and screw processing quality is higher.Use the hand wheel structure of tapping frame 3 to complete spinning movement simultaneously, rotate more fast and easy, efficiency is higher.
The lower floor of described tapping frame 3 is engraved structure.Can be convenient for people to like this check described cylindrical bars part 5 concrete conditions in tapping process.
Described holder 1 is designed to three and grabs chuck structure, and its underpart is designed with bits hole 11.Three while grabbing chuck gripping cylindrical component, can complete self-centering operation to part.Describedly fall to consider to be worth doing the iron filings that produce when hole 11 structures can guarantee tapping and drop easily.
