Abstract
The utility model discloses a special-purpose fixture for a numerical control lathe tap, which is used as a clamping tool of a tap to process inner threads of workpiece on a numerical control lathe. The special fixture comprises a tap clamping mechanism, a guide sleeve, an elastic reset mechanism and a fixed support, wherein the guide sleeve is fixed on the fixed support, the tap clamping mechanism is sleeved in the guide sleeve, and is connected with the elastic reset mechanism. The fixture is arranged on a tool holder of the numerical control lathe to process the inner threads of the workpiece. The special fixture has simple structure and convenient making, can firmly clamp the tap, uses the numerical control lathe to accurately control the depth of screw holes, and greatly increases the processing efficiency of the inner threads of the workpiece and the processing quality.
Description
Technical field
The utility model relates to the aid of machining, and especially numerically controlled lathe screw tap special fixture is used on the numerically controlled lathe, the internal thread of clamping screw tap processing work.
Background technology
For machining internal thread carries out the tapping operation, being common processing technology on engine lathe, generally all is to be fixed on the tailstock with hand-held screw tap machining internal thread or with screw tap to process.Big and dangerous with hand tapping labour intensity; Though tapping safety on tailstock, the screw degree of depth is wayward, the workpiece of machining internal thread on the region between the heart and the diaphragm hole particularly, the accident of the careless slightly screw tap that also can fracture.If machining internal thread on numerically controlled lathe, precision standard, efficient height, but do not have the instrument of clamping screw tap, can't utilize lathe in machining efficiently.
Summary of the invention
The purpose of this utility model is the defective that exists at prior art, and numerically controlled lathe screw tap special fixture is provided, and utilizes numerically controlled lathe, improves the working (machining) efficiency of internal thread workpiece.
The present technique solution can reach above-mentioned purpose: numerically controlled lathe screw tap special fixture comprises screw tap clamping device, fairlead, elastic reset mechanism and fixed support, fairlead is fixed on the fixed support, the screw tap clamping device is set in the fairlead, and mechanism is connected with elastic reset.These anchor clamps are installed on the knife rest of numerically controlled lathe the internal thread of processing work.
The beneficial effects of the utility model are: the utility model provides the special fixture of screw tap for numerically controlled lathe, can be on numerically controlled lathe with the internal thread of screw tap processing work.This clamp structure is simple, is convenient to make, and is easy to operate.The clamping screw tap utilizes numerically controlled lathe accurately to control the degree of depth of screw securely, and the internal thread of processing blind hole or stepped hole improves the working (machining) efficiency and the crudy of workpiece internal thread greatly, has also protected screw tap simultaneously, has prolonged the service life of screw tap.
Description of drawings
Accompanying drawing is that the utility model is installed and used schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, numerically controlled lathe screw tap special fixture comprises screw tap clamping device, fairlead 2, elastic reset mechanism and fixed support 4, fairlead 2 is fixed on the fixed support 4, the screw tap clamping device is set in the fairlead 2, and mechanism is connected with elastic reset.The screw tap clamping device comprises sliding sleeve 1 and the fixing office of screw tap, and screw tap fixedly office is installed in the front end cavity of sliding sleeve 1.Screw tap fixedly office comprises fixed cover and self-locking spring, and self-locking spring is installed in the rear end of fixed cover, and the card pearl is housed in the body wall of fixed cover.Circle is provided with groove and step in the front end cavity of sliding sleeve 1, and groove is fixed the interior card pearl of machine-operated fixed cover with screw tap and cooperated, and in the place ahead of step self-locking spring is installed, and the cavity body structure at step rear cooperates with the rear end shank of screw tap 6; The rear portion cylindrical of sliding sleeve 1 is provided with keyway.Fairlead 2 is cylindrical body, and an end is provided with centre bore and cooperates with the pull bar of elastic reset mechanism; Circle being provided with keyway in its cylindrical shell, is connected, cooperates with feather key with the cylindrical of the sliding sleeve 1 of screw tap clamping device.Elastic reset mechanism comprises pull bar, spring 3 and end cap, and pull bar is connected with end cap, and spring 3 is set on the pull bar.The sliding sleeve 1 of screw tap clamping device is connected with the pull bar of elastic reset mechanism.Screw tap 6 is fixed on these anchor clamps by the screw tap clamping device, the fixing office of the screw tap of screw tap clamping device band auto-lock function, screw tap 6 is fixedly positioning, fairlead 2 guiding screw taps 6 move axially, and prevent that screw tap 6 from rotating, it is ready that elastic reset mechanism makes screw tap 6 be reset to next part part processing, and fixed support 4 is fixed on the knife rest of Digit Control Machine Tool these anchor clamps.
During use, finish the procedure of numerically controlled lathe, 6 pairs on screw tap is good, fixing.Start numerically controlled lathe, make knife rest drive these anchor clamps and screw tap 6 axial displacements, behind workpiece 5, the beginning tapping.In the time of at the bottom of screw tap 6 is near the hole of workpiece 5, the main shaft of numerically controlled lathe stops operating, and several millimeters of these anchor clamps elder generations rollbacks are to eliminate the gap.The main shaft of numerically controlled lathe counter-rotating afterwards, these anchor clamps drive screw tap 6 and press the processing request rollback simultaneously, and after screw tap 6 withdrawed from workpiece 5, under the effect of these anchor clamps elastic reset mechanism, the screw tap clamping device resetted, and finishes whole process.
