Abstract

The utility model discloses a screwing frame for processing inner thread and outer thread; the functions of a screw tap twisted handspike and a die handle are connected into integration in the screwing frame; the screwing frame is composed of a main body, a handle, an adjusting screw tap clamping head, or a die sheathing ring; the adjusting screw tap clamping head or the die sheathing ring are arranged in the centre hole of the main body; when the inenr thread is tapped, the adjusting screw tap clamping head is adopted; when the outer thread is processed, the die sheathing ring is adopted; all the screw tap clamping heads and the die sheathing rings share one handle and one main body together; the utility model has the advantages of simple structure, convenient operation, reduction of tool carrying amount.

Description

A kind of turntable of processing internal and external threads

The utility model relates to a kind of turntable that the wired awl of internal and external threads fashionable dress or screw die are used of processing.

Be screw tap to be installed in carry out manual processing on the clutch tap holder during machining internal thread of production scene at present, used clutch tap holder is divided into two kinds on fixing strand thick stick and adjustable strand thick stick, fixing strand thick stick can only be used for the processing of maximum three kinds of specification screw taps, though adjustable strand thick stick range of application is wideer slightly, but because its structural limitations, make screw tap add stressed difficult equilibrium in man-hour, thereby influenced screw thread processing to a certain extent; Screw die is generally adopted in external screw thread processing at present in the production scene, specifically be that screw die load plate retainer is carried out, and die handle is according to the configuration design of screw die, and a kind of screw die of external diameter just needs a die handle.From as can be seen last, for adapting to the needs of producing, the production scene must be equipped with the clutch tap holder and the die handle of all size, and this has caused great inconvenience to the producer.

The purpose of this utility model is to provide a kind of turntable of processing internal and external threads, and the function of this turntable collection clutch tap holder and die handle is an one, and is not only easy to use, reliable, but also has significantly reduced the amount of carrying and the use amount of instrument.

For achieving the above object, the solution that the utility model adopts is: adjustable-tap dop or screw die lasso are installed in the main center hole, and two head of screws on adjustable-tap dop or the screw die lasso lay respectively in two earholes on the main body

Above-mentioned adjustable-tap dop is made up of disk, adjustable fixture block and adjustment screw, and wherein disk central authorities have a mounting hole, and two adjustable fixture blocks are positioned at mounting hole, and two adjustment screw lay respectively at the top of two adjustable fixture blocks.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Structure chart when Fig. 1 installs the adjustable-tap dop for the utility model.

Structure chart when Fig. 2 installs screw die for the utility model.

Fig. 3 is the profile of Fig. 1 along the I-I line.

What install in the main body shown in Figure 1 is the screw tap dop, uses when it is used to attack the strand internal thread, and what install in the main body shown in Figure 2 is the screw die lasso, uses when it is used for threading.From Fig. 1, Fig. 3 can find out, the utility model is by handle 1, main body 2 and adjustable-tap dop are formed, wherein handle 1 is symmetrically fixed on main body 2 both sides, be symmetrically distributed with two earholes on the main body 2, the adjustable-tap dop is installed in the centre bore of main body 2, and it is fixing with dog screw 3, among the figure, the adjustable-tap dop is by disk 4, adjustable fixture block 5 and adjustment screw 6 are formed, wherein disk 4 central authorities have a mounting hole, two adjustable fixture blocks 5 (V-arrangement slide block and M shape slide block) are positioned at mounting hole, adjustment screw 6 is positioned at the top of two adjustable fixture blocks 5, and it can regulate the gap between the two adjustable fixture blocks 5, with the screw tap of clamping different size size, adopt this two adjustable fixture block structure can also easily screw tap be fixed on the turntable center in addition, the balance of strength when being beneficial to hank knotting, when specifically installing, the head of two adjustment screw 6 is loaded on respectively in two earholes, such two adjustment screw 6 not only can play the effect of regulating fixture block 5, also can play the effect of carry-over moment when attacking the strand internal thread.Structure chart when Fig. 2 is the utility model threading, as can be seen from Figure, the utility model is made up of handle 1, main body 2 and screw die lasso 7, screw die lasso 7 is pressed the screw die specifications design, pair of screws 8 is arranged as clamping screw die usefulness on it, after screw die lasso 7 was put into main body 2, the head of screw 8 was positioned at two earholes of main body 2, when threading, this screw 8 can play the effect of carry-over moment.Above-mentioned screw tap dop and screw die lasso can a shared main body 2 and handles 1, the screw tap dop is installed on the main body when attacking internal thread, main body upper mounting plate facing circle when the needs threading, like this with replacing seven, eight die handles and strand thick stick once the cover turntable, under the situation that guarantees screw processing quality, significantly reduced the amount of carrying of instrument.

The utility model compared with prior art has following advantage: (1) structure letter Single, dependable performance; (2) integrate the function of clutch tap holder and die handle, use Scope is wide; (3) easy to use, greatly reduced the amount of carrying of instrument.
