Technical field
The present invention relates to lathe positioning fixture technical field is and in particular to a kind of hollow shaft type parts gear hobbing process is quickly fixed Position fixture.
Background technology
The large scale industry such as the energy, metallurgy, building materials, mine gear typically has that modulus is big, weight weight, high precision the features such as, Part in process, according to tapping traditional clamping centering mode such as part, alignment time length, labor strength Greatly, safety is difficult to ensure that, and easily leaves the vestige beaing on part to be processed, so that destroying the attractive in appearance of part.
Content of the invention
It is an object of the invention to overcoming drawbacks described above, provide a kind of simple, the quick positioning of structure, production efficiency high sky Heart axial workpiece gear hobbing process Quick-positioning clamp.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that:A kind of hollow shaft type parts gear hobbing process is fast Fast positioning fixture, including clamp base 1, positioning seat 2, cushion cover 3, positioning ringfeder 4, pull bar 5, upper press cover 6, under clamp base 1 End is fixed on platen 16 by 6 groups of T-slot bolts 14, hexagonal socket nut 13 and big spring packing ring 15, described fixed The lower plane of position seat 2 passes through 6 groups of positioning seat holding screws 18 and middle spring washer 19 is fixed on the upper plane of clamp base 1, pad Set 3 passes through cushion cover holding screw 10 and little spring packing ring 11 is fixed on the cascaded surface of positioning seat 2, the lower plane of positioning ringfeder 4 It is connected with cushion cover 3, the external cylindrical surface on its top inner conical surface and positioning seat 2 top is worked in coordination, and pull bar 5 sequentially passes through from top to bottom The centre bore of positioning ringfeder 4, positioning seat 2 and clamp base 1, and fixing with ringfeder holding screw 9 and positioning ringfeder 4 between, draw The lower end of bar 5 is connected with machine tool hydraulic oil cylinder 17 by screw thread, and one end of hollow shaft type parts 8 is sleeved on the outer of positioning ringfeder 4 On the face of cylinder, the other end is fitted with upper press cover 6, carries out axial restraint by lathe top 7.
Preferably, penetrate pull bar stop screw 12 in the cross through hole of positioning seat 2, and its head extends pull bar In 5 kidney-shaped slotted eye.
The present invention drives positioning ringfeder to move up and down along the conical surface using pull bar, makes hollow shaft type parts and positioning ringfeder Fiting property changes, and realizes quickly positioning during gear hobbing, greatly shortens correction time, improves gear hobbing efficiency.

Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described further.
As shown in Fig. 1~8, hollow shaft type parts gear hobbing process Quick-positioning clamp includes clamp base 1, positioning seat 2, pad Set 3, positioning ringfeder 4, pull bar 5, upper press cover 6,6 groups of T-slot bolts 14, hexagonal socket nuts 13 are passed through in the lower end of clamp base 1 It is fixed on platen 16 with big spring packing ring 15, the lower plane of described positioning seat 2 passes through 6 groups of positioning seat holding screws 18 It is fixed on the upper plane of clamp base 1 with middle spring washer 19, cushion cover 3 passes through cushion cover holding screw 10 and little spring packing ring 11 is solid It is scheduled on the cascaded surface of positioning seat 2, the lower plane of positioning ringfeder 4 is connected with cushion cover 3, its top inner conical surface and positioning seat 2 top External cylindrical surface work in coordination, pull bar 5 sequentially passes through positioning ringfeder 4, the centre bore of positioning seat 2 and clamp base 1 from top to bottom, And fixing with ringfeder holding screw 9 and positioning ringfeder 4 between, the lower end of pull bar 5 is connected with machine tool hydraulic oil cylinder 17 by screw thread, One end of hollow shaft type parts 8 is sleeved on the external cylindrical surface of positioning ringfeder 4, and the other end is fitted with upper press cover 6, by lathe top Point 7 carries out axial restraint.
Penetrate pull bar stop screw 12 in the cross through hole of positioning seat 2, and its head extends the kidney-shaped slotted eye of pull bar 5 In, play the effect limiting the upper and lower stroke of pull bar.
The lower end of hollow shaft type parts 8 is contacted with upper press cover 6 with the cooperation of positioning ringfeder 3 gap, upper end, lathe top 7 It is pressed on the centre bore of upper press cover, realize the axially position of part.When part is processed, the machine tool hydraulic oil cylinder of pull bar 5 lower end 17 is descending, realizes the drop-down action of pull bar, and pull bar drives positioning ringfeder to move down, and ringfeder is along conical surface swell, part and positioning ringfeder Gap cooperation is changed into interference fit, realizes radial positioning.The pull-down stroke of pull bar passes through kidney-shaped slotted eye and positioning on pull bar Pull bar stop screw 12 on seat limits.When part completion of processing, machine tool hydraulic oil cylinder is up, and pull bar drives positioning ringfeder along cone Move on face, part is changed into gap cooperation with the interference fit of positioning ringfeder.
The present invention is not limited to above-mentioned embodiment, the ken possessing in art those of ordinary skill Interior, can also make a variety of changes on the premise of without departing from present inventive concept and principle.
