Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, 1-7 and specific embodiment carry out clear, complete description to utility model below in conjunction with the accompanying drawings.

A kind of thread tapping fixture as illustrated in figs. 2-7, it includes base 1, vertical set 2, elastic clamping body 3 and pressure female 4, it is provided with round platform 1-1 on described base 1, it is provided with centre bore 1-2 on described round platform 1-1, described vertical set 2 is fixed in described centre bore 1-2, described vertical set 2 center is pilot hole 2-1, and the oral area 2-2 of described pilot hole 2-1 is tapered.

Described elastic clamping body 3 is fitted in described pilot hole 2-1, elastic clamping body 3 lower end is to be suitable for the oral area 2-2 cone table 3-2 with described taper with described cylinder 3-1 suitable for pilot hole 2-1, upper end, described elastic clamping body 3 central upper portion is to be used for clamping the shoulder hole 3-3 of workpiece (such as feeler lever 7), the groove 3-4 from top to bottom extended of one or more is set on its sidewall, in the present embodiment, described groove 3-4 is three, article three, groove 3-4 is uniformly distributed on elastic clamping body 3 sidewall, and described groove 3-4 width is 2mm, the degree of depth is 25mm.Described vertical set 2 upper end is provided with pressure female 4, and described pressure female 4 applies downward pressure to the top of described cone table 3-2.It is provided with handle 5 on female 4 sidewalls of described pressure.Pressure female 4 is rotated by handle 5 is convenient.

Described round platform 1-1 sidewall is provided with location hole 1-3, is provided with connecting hole 2-3 bottom described vertical set 2, and hole, described location 1-3 content is connected with connecting hole 2-3 by location screw 6.It is provided with for the through hole 1-4 through bolt on described base 1.Fixing bolt is connected fixing with drilling machine pedestal 9 for base 1 through described through hole 1-4, and the feeler lever 7 being fixedly clamped by device is by drilling machine drive system 8 tapping in the central blind hole 7-1 of feeler lever 7.

Base 1 material is No. 45 steel, and base 1 surrounding has the through hole 1-4 of 4 ￠ 6.5mm for being connected and fixed this fixture through fixing bolt 10 and drilling machine pedestal 9.Round platform 1-1 external diameter on base 1 is ￠ 48mm, and centre bore 1-2 a diameter of ￠ 28mm, centre bore 1-2 of round platform 1-1 is used for and vertical set 2 is equipped with and supports vertical set 2.The hole, two location of round platform 1-1 lateral surface is the screwed hole of M6, after vertical set 2 and base 1 are equipped with, with the screw of 2 M6, through this hole, vertical set 2 and base 1 is positioned fastening.

Vertical set 2 materials are No. 45 steel, and its underpart is equipped with in the cylindrical centre bore 1-2 with the ￠ 28mm on base, and vertical set 2 has the connecting hole 2-3 of the location of 2.Vertical set 2 outer surface of upper are M26 screw thread, and central upper portion has the pilot hole 2-1 of ￠ 16, and the oral area 2-2 of pilot hole 2-1 is in the cone conical surface, and its tapering is 30, and the degree of depth is 5mm.

The material of elastic clamping body 3 is copper material, and its underpart cylinder 3-1 external diameter is ￠ 16, and the pilot hole 2-1 of the ￠ 16 of cylinder 3-1 and vertical set 2 is equipped with, and structure is as shown in Figure 2.Elastic clamping body 3 top is cone 3-2, and the big footpath of taper is ￠ 19.5, path is ￠ 14, tapering is 30, the degree of depth is 9mm.Elastic clamping body 3 central upper portion is ￠ 14, the shoulder hole 3-3 of ￠ 8.5.

The inner conical surface of the cone 3-2 on elastic clamping body 3 top and vertical set is equipped with.￠ 14, the shoulder hole of ￠ 8.5 need the feeler lever part of tapping for placement.The outer surface of elastic clamping body uniformly opened 3 width be 2mm, the degree of depth be the groove 3-4 of 25mm, therefore elasticity has been arranged at the top of elastic clamping body 3, when it is by radially outward force effect, contraction distortion can be produced, contraction is diminished by the hole of middle ￠ 14, give feeler lever part one circumferential pressure, thus feeler lever part is uniformly held tightly, it is achieved fixing of feeler lever part.

Having the centre bore of ￠ 15 in pressure female 4, there is M26 screw thread inner side, is used for and vertical set 2 connection.When the pressure that turns clockwise is female, pressure mother moves down, and when pressing mother to move to certain position, pressure mother contact with elastic clamping body, drives elastic clamping body 3 to move downwardly together.Handle 5 and pressure female 4 thread connection, be used for rotating pressure female 4.

During assembling, first vertical set 2 and base 1 are equipped with, then are screwed into hole, the location 1-3 of base from side with two location screws, until screw end face contacts with by the locating surface of vertical set 2, vertical set 2 and base 1 are fixed.Then elastic clamping body 3 is loaded in the pilot hole 2-1 of vertical set 2.Make the conical surface and the taper-face contact of elastic clamping body of vertical set 1.Again handle 5 and pressure female 4 are fixed by thread connection, finally pressure female 4 is screwed on vertical set 2 by thread connection.

This fixture working example figure is as shown in Figure 7.During work, first this fixture is placed on drilling machine pedestal, adjusts the position of this fixture, with screw, this fixture and drilling machine pedestal will be fastened behind this fixture elastic clamping body center and drilling machine drilling rod central alignment.Then the feeler lever part of machined good bottom outlet is placed in elastic clamping body ￠ 14 centre bore, now, between elastic clamping body and feeler lever part, there is gap, so feeler lever is in free state.When needing tapping, rotating clockwise handle with hands, pressure mother just moves down along vertical set axial direction, and when pressing mother to move to certain position, pressure mother contact with elastic clamping body.While pressure mother continues to move down, elastic clamping body is driven also to move down, while elastic clamping body moves down, the circumferential thrust given by vertical set, so, elastic clamping body circumference uniform shrinkage, ￠ 14 bore dia will diminish, and uniformly be clamped by feeler lever.Feeler lever is in tightening state, now, utilizes drilling machine and screw tap they can be carried out tapping work.Owing to elastic clamping body material is copper material, hardness is relatively low, so elastic clamping body is when clamping feeler lever, feeler lever surface will not be produced impression, can well ensure that the surface quality of feeler lever.After tapping completes, the rotation direction of wraparound drill press belt pulley, after being exited by screw tap, rotate counterclockwise handle, pressure mother is upper to move.Meanwhile, elastic clamping body relies on the elastic force of self, returns to initial condition, relieves the thrust to feeler lever.Now operator can take out feeler lever part with hands or accessory, completes the tapping work of a feeler lever part.Operator can be with the same next feeler lever part of method processing.

Carry out the screwing operation of feeler lever part with this fixture, working (machining) efficiency is the highest, can process about 300 per hour.

Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in previous embodiment still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model embodiment technical scheme.
