Abstract
The utility model discloses a bearing bush broaching machine clamping device which comprises a bearing bush. The bearing bush is clamped onto an inner tube film through an elastic clamping block. The elastic clamping block is connected with a split supporting seat through screws. A middle supporting seat, a base and a piston fixing block four-grade support are sequentially arranged below the split supporting seat. The split supporting seat is fixedly clamping to a piston rod in the vertical direction and the transverse direction through screws. Cylindrical-face locating bosses are respectively arranged on the base, the middle supporting seat and the split supporting seat. Steel ball spring plungers are inlaid on four corners. The bottom face of the elastic clamping block is provided with a V-shaped molded surface with clearance. The V-shaped face is in linear fit with the cylindrical-face locating boss on the split supporting seat. The middle position of the cylindrical-face locating boss on the base, the middle position of the cylindrical-face locating boss on the middle supporting seat and the middle position of the cylindrical-face locating boss on the split supporting seat are connected with one another through locating screws. An outer tube film is located on a beam of a broaching machine through a key and is fastened through four screws. The bearing bush broaching machine clamping device is used in the automobile bearing bush machining industry.
Description
Technical field:
The utility model relates to a kind of bearing shell broaching machine gripping mechanism, is specially adapted to automobile bearing processing industry.
Background technology:
Along with developing rapidly of automobile industry, bearing shell process equipment efficiency and precision are all expected to improve, current domestic bearing shell broaching has horizontal and vertical two kinds of broaching forms, bearing shell is realized broaching in fetal membrane after clamping, each operation cycle a slice of can only broaching, production efficiency is per minute only has 10-11 sheet, broaching bearing shell depth of parallelism 0.02mm, and radius is high by 0.03～0.05.Its shortcoming is: 1, gripping mechanism can only clamp a slice bearing shell at every turn, monolithic broaching; 2, clamping jacking block slotting in middle, communicates with bottom circle nest, in circle nest, puts steel ball, by piston rod, holds out against steel ball, realizes the stressed bullet of single-point and rises, and because the jacking block bullet amount of rising is inadequate, bearing shell coincide bad in fetal membrane, and bearing shell broaching dimensional uniformity is poor; 3, clamping jacking block is stressed bad closing screw, often fracture; 4, fetal membrane is directly fixed on crossbeam by four screws, and positioning precision does not have structure to guarantee, entirely by the adjustment of debugging work, and while changing product, effort when precision is adjusted.
Summary of the invention:
Task of the present utility model is to propose a kind of working (machining) efficiency to improve, and it is convenient while changing product, to change, a kind of bearing shell broaching machine gripping mechanism of failure rate is low.
Task of the present utility model completes like this, a kind of bearing shell broaching machine gripping mechanism, it comprises bearing shell, it is characterized in that: bearing shell is clamped on interior fetal membrane by elasticity clamping block, described elasticity clamping block is connected with split bearing with screw, intermediate support is housed below split bearing successively, base, piston fixed block level Four supports, with screw vertical direction and be laterally fixedly clamped on piston rod, described base, above intermediate support and split bearing, be all respectively arranged with face of cylinder positioning boss, on four angles, stud with steel ball and spring plunger, the bottom surface of elasticity clamping block has with the V-type face in gap and the face of cylinder locating convex block on split bearing and is linear fit, the centre position of base intermediate support and face of cylinder positioning boss on split bearing is connected with dog screw, outer fetal membrane is positioned on broaching machine crossbeam with four screw fastenings by key.
The utlity model has following effect: once clamp two bearing shells, two of each operation cycle broachings, realize the bearing shell 25-30 sheet per minute of broaching, working (machining) efficiency improves 2.5-2.7 doubly, broaching bearing shell depth of parallelism 0.015mm, the high 0.02mm of radius, bearing shell broaching precision improves 1 times, four one unique linear elasticity clamping structures, realize bearing shell automatic capturing in fetal membrane, be identical, guarantee the high high conformity of bearing shell broaching radius, take leave of in the past traditional monolithic single-point bullet formula clamping that rises, adopt this bearing shell broaching gripping mechanism, rational in infrastructure, failure rate is low, lathe stability is high, fetal membrane structure is unique, be refined as outer fetal membrane and interior fetal membrane.Outer fetal membrane immobilizes, precision is guaranteed by lathe processing itself, during conversion product, only need to change interior fetal membrane, the processing of bearing shell accessory is simple, and it is convenient to change, facilitate the variation of product small lot, gripping mechanism modularized design, a kind of product of every conversion, in needing to change, fetal membrane and clamping block combination are a set of, the replacing time needs only 20 minutes, greatly shortens the new product preparatory period.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the cutaway view of Figure 1A-A direction.
Drawing explanation: 1, piston rod, 2, fixed block, 3, screw, 3-4, screw, 5, base, 6, intermediate support, 7, dog screw, 8, split bearing, 9, steel ball and spring piston, 10, elasticity clamping block, 11, interior fetal membrane, 12, bearing shell, 3-13, screw, 14, outer fetal membrane, 15, key, 16, crossbeam, 17, pressing plate, 3-18 screw, 3-19 screw.
The specific embodiment:
The utility model consists of spring clamping device and fetal membrane, spring clamping device is partly by seeing shown in Fig. 1 and Fig. 2, bearing shell 12 is clamped on interior fetal membrane 11 by elasticity clamping block 10, realize bearing shell broaching, elasticity clamping block 10 use screw 3-13 are connected with split bearing 8, split bearing 8 is equipped with intermediate support 6 below successively, base 5, piston fixed block 2 level Four support, with screw 3 vertical directions and screw 3-4, be laterally fixedly clamped on piston rod 1, described base 5, above intermediate support 6 and split bearing 8, be all respectively arranged with face of cylinder positioning boss, on four angles, stud with steel ball and spring plunger 9, the supporting construction feature of this multistage form is: base 5, the every centre between the two of intermediate support 6 and split bearing 8 all adopts face of cylinder linear orientation, and four steel ball and spring plunger 9 supplemental support for angle, intermediate support 6 guarantees that bearing shells 12 are at the left and right directions centering that can float, split bearing 8 has two, realize two bearing shell clampings, guarantee that bearing shell is at fore-and-aft direction automatic capturing, the bottom surface of elasticity clamping block 10 has with the V-type face in gap and the face of cylinder locating convex block on split bearing 8 and is linear fit, when piston rod 1 rises, while realizing bearing shell 12 clamping, elasticity clamping block 10 is under the support of the face of cylinder of split bearing 8 positioning boss, realize elasticity, make 10 3 of elasticity clamping blocks together with bearing shell 12 contacts at the interior automatic capturing of interior fetal membrane 11, be identical, thereby guarantee the consistent of bearing shell 12 broaching sizes, in gripping mechanism combination, the centre position of base 5 intermediate supports 6 and face of cylinder positioning boss on split bearing 8 is connected with dog screw 7, when elasticity clamping block 10 is stressed, all bearing axial locations can not slide along the face of cylinder, guarantee bearing shell 12 centering that can only float in fetal membrane, but can not slide and come off, to realize the accurate broaching of bearing shell.
