Its accessible screw tap or die replace lathe tool tapping cover and detain, and at tapping cover and detain the in-process, screw tap or die self-feed need not to calculate again strictly and debug repeatedly, great reduction intensity of labour, labour saving and time saving improves machining efficiency.

Description

Tapping sleeve fastener tool for machine tool

Technical Field

The utility model relates to a tapping lasso detains equipment, especially relates to a tapping lasso detains instrument for lathe.

Background

The tapping sleeve button refers to a process for processing internal threads or external threads on a workpiece. At present, a tapping threading mode is to clamp a workpiece on a chuck of a machine tool and turn internal threads or external threads of the workpiece by using a lathe tool. Because the size requirement of the internal thread or the external thread which is screwed out by the tapping sleeve is strict, the turning angle and the feeding speed of a lathe turning tool can be determined by strict calculation and repeated debugging in the tapping sleeve screwing process, so that the tapping sleeve screwing is high in labor intensity, time-consuming, labor-consuming and low in processing efficiency.

Disclosure of Invention

The utility model relates to a solve above-mentioned technical problem, provide a tapping threading instrument for lathe, its accessible screw tap or die replace lathe tool tapping threading cover to be detained, at tapping cover knot in-process, screw tap or die feed by oneself, need not again through strict calculation and debugging repeatedly, great reduction intensity of labour, labour saving and time saving improves machining efficiency.

The technical solution of the utility model is that:

tapping toggle tool for lathe, including the dead lever, its special character lies in: the front end of the fixed rod is provided with a pipe sleeve, an axially moving telescopic rod is inserted in the pipe sleeve, the front end of the telescopic rod is fixedly provided with a universal coupling, the universal coupling is sleeved with a positioning sleeve, the front end of the universal coupling is coaxially provided with a chuck, and jaws of the chuck are arranged forwards.

Further preferably, the telescopic rod is matched with the pipe sleeve through a spline, and the telescopic rod and the pipe sleeve can only axially move relatively.

Preferably, the chuck is a four-jaw chuck, and four jaws of the four-jaw chuck are matched with four positioning surfaces at the tail end of the tap.

Further preferably, the friction surface is arranged on the outer circular surface of the pipe sleeve, so that the friction force of the pipe sleeve is increased, and the pipe sleeve is prevented from slipping off by hands during carrying and mounting.

Further preferably, the fixing rod is conical, so that the fixing rod can be conveniently inserted into a chuck of a lathe.

The utility model has the advantages that:

1. because establish the pipe box at the dead lever front end, insert the telescopic link of axial displacement in the pipe box, the chuck of coaxial arrangement at universal coupling front end, when tapping hitch operation, install the dead lever at the lathe tailstock at first, install screw tap or die at the chuck, install the machined part at the lathe chuck, then axial displacement telescopic link inserts the screw tap into the internal thread machining hole of machined part or overlaps the die at the machined part disc of excircle with the die, start the lathe at last, the lathe chuck drives the machined part and rotates, in the machined part rotation process, under telescopic link and sleeve pipe axial slip effect, screw tap or die automatic axial tapping hitch replace traditional lathe tool tapping hitch processing mode, need not to again through strict calculation and debugging repeatedly, great reduction intensity of labour, time and labor saving, machining efficiency is improved.

2. Because of the universal coupling connected between the chuck and the telescopic rod and the positioning sleeve sleeved on the universal coupling, the sliding positioning sleeve is sleeved on the two connectors of the universal coupling, so that the two connectors of the universal coupling are coaxial to perform tapping processing; the sliding positioning sleeve is sleeved on one connector, so that the two connectors of the universal coupling are in a free state, the slender workpieces such as reinforcing steel bars are tapped, the dies synchronously swing along with the swinging in the sleeving and buckling process of the slender workpieces such as the reinforcing steel bars, rigid processing and flexible processing can be switched, and the processed threads are ensured to meet the requirement of thread size.

in the figure: the universal joint comprises a fixing rod 1, a pipe sleeve 2, a friction surface 3, a telescopic rod 4, a spline 5, a universal coupling 6, a positioning sleeve 7 and a four-jaw chuck 8.

Detailed Description

As shown in fig. 1-3, the tapping threading tool for machine tool comprises a conical fixing rod 1, a pipe sleeve 2 is arranged at the front end of the fixing rod 1, a friction surface 3 is arranged on the outer circular surface of the pipe sleeve 2, an axially moving telescopic rod 4 is inserted in the pipe sleeve 2, the telescopic rod 4 is matched with the pipe sleeve 2 through a spline 5, a universal coupling 6 is fixedly arranged at the front end of the telescopic rod 4, a positioning sleeve 7 is sleeved on the universal coupling 6, a four-jaw chuck 8 is coaxially arranged at the front end of the universal coupling 6, and jaws of the four-jaw chuck 8 are arranged forward.

During tapping operation, the fixing rod 1 is installed on a lathe tailstock at first, the screw tap is installed on the four-jaw chuck 8, the internal thread machined part is installed on the lathe chuck, then the sliding positioning sleeve 7 is sleeved on the two connectors of the universal coupling 6, the two connectors of the universal coupling 6 are coaxial, the telescopic rod 4 is axially moved to insert the screw tap into the internal thread machining hole of the internal thread machined part, the lathe is started at last, the lathe chuck drives the internal thread machined part to rotate, and in the rotating process of the internal thread machined part, the screw tap performs automatic axial tapping along the internal thread machining hole of the internal thread machined.

During the threading operation, at first install dead lever 1 at the lathe tailstock, install the threading die at four-jaw chuck 8, install the reinforcing bar at the lathe chuck, then slip position sleeve 7 cover is at one of them connector, make two connectors of universal coupling 6 be free state, axial displacement telescopic link 4 covers the threading die at reinforcing bar front end excircle face again, start the lathe at last, the lathe chuck drives the reinforcing bar and rotates, and in the reinforcing bar rotation process, the threading die is along the automatic axial tapping of reinforcing bar excircle face.

The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
