Abstract
The utility model discloses a protection apparatus which renders protections when tapping is overloaded. The apparatus comprises a knife rod which has a taper handle. One end of the knife rod is provided with a groove whose inner wall is arranged with a sliding slot; the groove is provided with a spring and the other end of the spring is provided with connection plates referred to as an upper connection plate and a lower connection plate which are engaged together; the outside screws of the groove are provided with adjusting nuts to adjust the compression degree of the spring and pressing nuts to fasten and fix. The apparatus of the utility model is not only simple in structure and convenient to use but also innovative in design, safe and reliable and protective to make a screw tap not so easily broken.
Description
Technical field
The utility model relates to a kind of device of protective effect, particularly a kind of device that when tapping is transshipped, shields.
Background technology
Current, tapping is one of important content in the pincers worker metal cutting, comprises links such as line, boring, tapping; The crudy of screw thread directly has influence on the assembly quality effect of member; When on steel components, attacking the system screw thread, can use the conventional tool of this processing column shape of screw tap and conical internal thread, because screw tap is easy to generate retardance; The cutting moment of torque is increased and the screw tap that fractures, so prior art still is not ideal enough suddenly.
Summary of the invention
The purpose of the utility model is: a kind of simple in structure, easy to operate, safe and reliable, a kind of device that when tapping is transshipped, shields of not fractureed of protection screw tap is provided, to overcome the deficiency of prior art.
The utility model is to be constructed as follows: a kind of device that when tapping is transshipped, shields; Comprise the knife bar of being with taper shank; End at knife bar is provided with groove, and the inwall of groove is provided with chute, spring is installed in groove, is provided with conjoint disk at the other end of spring; Last conjoint disk is mutually meshing with following conjoint disk, and the external screw thread of groove is provided with the adjusting nut and the clamp nut that is used for fastener of adjustable springs decrement.
Last conjoint disk is provided with the sliding handle that can in chute, slide, and following conjoint disk is provided with the square hole of the tapping screw tap of packing into.
Last conjoint disk is provided with meshing stepped tooth each other with following conjoint disk.
Owing to adopted technique scheme, when using this device, at first spring, last conjoint disk are encased in the groove of knife bar with following conjoint disk, load onto adjusting nut then; After adjusting the position, screw in clamp nut and fix the tapping screw tap of packing in the square hole; When the cutting moment of torque of screw tap affacted on the conjoint disk and is raised to a certain setting, following conjoint disk also reached a certain value to the axial force of last conjoint disk thereupon, until promoting to go up the pressure that conjoint disk overcomes spring; Last conjoint disk upwards slides along chute, and upper and lower conjoint disk is thrown off, and skids; Lift main shaft this moment, and screw tap promptly can not fracture, compared with prior art; The utility model not only has advantage simple in structure, easy to use, and design ingenious, safe and reliable, can protect advantages such as screw tap is not fractureed.

Description of reference numerals: 1-knife bar, 2-groove, 3-chute, 4-spring, the last conjoint disk of 5-, conjoint disk under the 6-, 7-adjusting nut, 8-clamp nut, 9-sliding handle, 10-square hole, 11-stepped tooth, 12-external screw thread.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The enforcement of the utility model: a kind of device that when tapping is transshipped, shields; Shown in Fig. 1～5; A kind of device that when tapping is transshipped, shields comprises the knife bar 1 of being with taper shank, is provided with groove 2 at an end of knife bar 1; The inwall of groove 2 is provided with chute 3; Spring 4 is installed in groove 2, is provided with conjoint disk 5 at the other end of spring 4, last conjoint disk 5 is mutually meshing with following conjoint disk 6, and the external screw thread 12 of groove 2 is provided with the adjusting nut 7 and the clamp nut 8 that is used for fastener of adjustable springs 4 decrements.
When using the utility model, at first mounting spring 4 in the groove 2 of knife bar 1 is installed conjoint disk 5 in a side of spring 4; Last conjoint disk 5 is connected with following conjoint disk 6 through stepped tooth 11, after installing, the adjusting nut 7 and the clamp nut 8 that is used for fastener of adjustable springs 4 decrements is installed in the outside of groove 2; During work, knife bar 1 is passed to conjoint disk 5 with the machine tool chief axis output torque through chute 3 and sliding handle 9, and the stepped tooth 11 by 6 of last conjoint disk 5 and following conjoint disks passes to down conjoint disk 6 again; And driving the screw tap cutting workpiece, the axial compressive force between the upper and lower conjoint disk can be regulated by the decrement of spring 4, the decrement of adjusting nut 7 adjustable springs 4; The conjoint disk force transfer surface is an inclined plane, and it is different to attack system screw thread inclined plane, the left and right sides, can select the conjoint disk on different inclined planes to carry out work when needing; Therefore when the cutting moment of torque of screw tap affacts on the conjoint disk 5 and is raised to a certain setting; 6 pairs of axial forces that go up conjoint disk 5 of following conjoint disk also reach a certain value thereupon, and until promoting to go up the pressure that conjoint disk 5 overcomes spring 4, last conjoint disk 5 upwards slides along chute 3; Upper and lower conjoint disk is thrown off; Skid, lift main shaft this moment, and screw tap promptly can not fracture.
