Abstract
The invention provides a screw tap taking-out device which comprises a shaft provided with grooves. Clamping jaws are arranged in the grooves. The shaft is sleeved with a fixed sleeve ring which is fixed to the shaft through a screw. A sliding sleeve used for folding the clamping jaws is arranged on the position, between the fixed sleeve ring and free ends of the clamping jaws, of the shaft. Due to the fact that the grooves are formed in the shaft, the grooves obviously need to correspond to the number and shape of grooves in a screw tap, then the clamping jaws are embedded into the grooves, and the fixed sleeve ring is used for fixing the clamping jaws to the shaft. When the screw tap taking-out device is used, the clamping jaws stretch into a drilling hole, the sliding sleeve is moved to the free ends of the clamping jaws, then the free ends of the clamping jaws can be fixed in the grooves of the screw tap, and through the clamping of the sliding sleeve, the screw tap is enclasped by the clamping jaws, and therefore the screw tap broken in a product can be taken out easily.
Description
Technical field
The present invention relates to a kind of machine tools, be specifically related to a kind of device that takes out screw tap from boring.
Background technology
Tapping is the common processing mode in machining, once after still generation screw tap fractures, because the aperture of boring and the reason of the degree of depth are difficult to screw tap to be difficult to take out.Have to reselect again the place of tapping, cause substandard products.If rupture at the local screw tap of the necessary tapping of product, and cannot take out screw tap, will directly cause whole product rejection, cause serious waste.
Summary of the invention
The technical problem to be solved in the present invention is that screw tap fracture easily occurs existing product when tapping, and the screw tap of fracture is difficult to take out from product, causes substandard products or waste product, causes serious waste, has increased cost.
For achieving the above object, technical scheme of the present invention is: screw tap withdrawing device, comprise out fluted axle, and in described groove, be placed with claw, on described axle, be arranged with retaining collar, described retaining collar is fixed by screws on axle; On described axle, between retaining collar and claw free end, be provided with the sliding sleeve that draws claw in.
While adopting technique scheme, owing to offering groove on axle, obviously groove need to be corresponding with groove number and flute profile on screw tap, then be embedded in claw at groove, and utilize retaining collar that claw is fixed on axle.During use, claw is stretched in boring, sliding sleeve is shifted to the free end of claw, the free end of claw is just fixed in the groove of screw tap, and by the clamping of sliding sleeve, claw is held screw tap tightly, so just can like a cork the screw tap breaking in product be taken out like a cork.
Further, for convenient, claw is inserted in screw tap, the free-ended termination of described claw is taper.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of screw tap withdrawing device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, screw tap withdrawing device of the present invention, comprises the axle 1 that has groove 2, is placed with claw 3 in groove 2, is arranged with retaining collar 4 on axle 1, and retaining collar 4 is fixed on axle 1 by screw 5; On axle 1, between retaining collar 4 and claw 3 free ends, be provided with the sliding sleeve 6 that draws claw in.Owing to offering groove 2 on axle 1, obviously groove 2 need to be corresponding with groove number and flute profile on screw tap, then be embedded in claw 3 at groove 2, and utilize retaining collar 4 that claw 3 is fixed on axle 1.During use, claw 3 is stretched in boring, sliding sleeve 6 is shifted to the free end of claw 3, the free end of claw 3 is just fixed in the groove of screw tap, and by the clamping of sliding sleeve 6, claw 3 is held screw tap tightly, so just can like a cork the screw tap breaking in product be taken out like a cork.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. screw tap withdrawing device, is characterized in that, comprises out fluted axle, in described groove, is placed with claw, on described axle, is arranged with retaining collar, and described retaining collar is fixed by screws on axle; On described axle, between retaining collar and claw free end, be provided with the sliding sleeve that draws claw in.
2. screw tap withdrawing device according to claim 1, is characterized in that, the free-ended termination of described claw is taper.
