Abstract
The utility model provides a numerical control lathe floating tapping tool which comprises a sleeve and a floating rod. The floating rod is sleeved in the sleeve, one end of the floating rod extends out of the sleeve, a gap is reserved between the outer circumference of the floating rod and the inner circumference of the sleeve, a hole with an internal thread is formed in the floating rod and close to the side face of one end of the floating rod extending out of the sleeve, a limit screw is arranged in the hole, a limit block matched with the limit screw is arranged at one end of the sleeve and can function in limiting the floating rod to move along the tangent direction during tapping, and a mounting handle is arranged at one end of the floating rod extending out of the sleeve. The numerical control lathe floating tapping tool has the advantages that the tool effectively realizes coaxiality of a screw tap and an outer circle by the aid of the floating gap, the coaxiality of the thread and the outer circle is ensured, the problem of rigid breakage of the screw tap is effectively avoided, and the service life of the screw tap is prolonged.
Description
Technical field
The utility model belongs to machine components process unit field, especially relates to a kind of numerically controlled lathe float tapping frock.
Background technology
Generally screw tap is rigidly fixed on tool rest in existing technology, utilizes program to make itself and blank thread Pilot hole centering, utilize blank rotation and screw tap axially-movable to complete tapping process.The method is fixed (depending on program) because of screw tap and blank relative position, affected by blank clamping and blank appearance and size uniformity, easily causes the distortion of processing rear thread, screw thread and cylindrical disalignment, and easily causes screw tap to fracture, and cost is higher.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of numerically controlled lathe float tapping frock.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of numerically controlled lathe float tapping frock, comprise sleeve pipe and floating lever, a described floating lever part is placed in described sleeve pipe, remainder stretches out described sleeve pipe, there is gap between described floating lever external diameter and described casing inner diameter, stretching out on described sleeve portion of described floating lever is provided with stop screw near described sleeve pipe place, described sleeve pipe one end has with described stop screw and coordinates, play the tangentially limited block of motion effect of the described floating lever of restriction when tapping, the top that described floating lever stretches out described sleeve portion has installing handle.
Advantage and the good effect that the utlity model has are: this frock manufacture is simple, easy to operate, with low cost, between each parts, can change separately, and maintenance cost is low, is applicable to numerically controlled lathe and uses; This frock is utilized flying height, has effectively solved the axiality problem of screw tap and cylindrical, has guaranteed the axiality of screw thread and cylindrical, has effectively avoided the screw tap rigidity problem that fractures simultaneously, improves screw tap service life.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the sectional view of sleeve pipe;
Fig. 3 is the partial sectional view of floating lever.
In figure:
1, sleeve pipe 2, floating lever 3, stop screw

The specific embodiment
As shown in Figures 1 to 3, the utility model provides a kind of numerically controlled lathe float tapping frock, comprise sleeve pipe 1 and floating lever 2, floating lever 2 parts are placed in 1 pipe, remainder stretches out sleeve pipe 1, there is gap between floating lever 2 external diameters and sleeve pipe 1 internal diameter, stretching out on sleeve pipe 1 part of floating lever 2 is provided with stop screw 3 near sleeve pipe 1 place, sleeve pipe 1 one ends have with stop screw 3 and coordinate, play the tangentially limited block 5 of motion effect of restriction floating lever 2 when tapping, the top that floating lever 2 stretches out sleeve pipe 1 part has installing handle 4.
The course of work of this example: sleeve pipe 1 is rigidly secured on the numerically controlled lathe tool rest; Stop screw 3 is screwed on floating lever 2 in the hole with internal thread, then floating lever 2 is inserted in sleeve pipes 1; General Mohs drill chuck is installed on floating lever 2 leading portion installing handles 4; Screw tap is installed on general Mohs drill chuck.During tapping, High Rotation Speed after the blank clamping, numerically controlled lathe utilizes program to make screw tap centering relative to the blank thread Pilot hole, and during the axial blank motion of screw tap, screw tap utilizes floating lever 2 and 1 gap of sleeve centering centering voluntarily; Because stop screw 3 is stuck on the limited block 5 on sleeve 1, make screw tap tangentially can't rotate, thereby make screw tap and blank relative motion, screw tap incision thread Pilot hole, and then process internal thread.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
