Description
Technical field
The utility model relates to fin shaping machine field, is specifically related to a kind of displacement type endplay device.
Background technology
Tradition endplay device is made up of slide plate, rocking bar, cam and spacing adjusting nut; Rocking bar, spacing adjusting nut and the mechanism's stopping means that is struck need being coordinated jointly to adjust when adjusting spacing, when spacing has big difference, also needing the restructuring of dismounting rocking bar, so complicated operation, operation are loaded down with trivial details when adjusting.
In addition, traditional middle sled mechanism is made up of a slide plate, a cam and two camshaft bearings, because processing technology and allowable tolerance exist, cam coordinates difficulty with camshaft bearing, when contact gap is excessive, there is a transition gap in cam and camshaft bearing, namely in rocking bar work, there is a certain amount of neutral gear, also there is certain impact power simultaneously, cam and camshaft bearing are worn and torn and strengthens.
Summary of the invention
For the problems referred to above, technical problem to be solved in the utility model is to provide a kind of displacement type endplay device, and it is directly perceived simple that it makes fin tooth pitch adjust.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of displacement type endplay device, comprise striking gear and tooth pitch adjusting device, described striking gear comprises middle slide plate, middle slide plate base, cam, rocking bar, driving lever and slide plate, and described middle slide plate lower end is connected with middle slide plate base by line slideway; Described cam is positioned at middle slide plate, and inside described middle slide plate right-hand member, be provided with camshaft bearing, this camshaft bearing part is placed in middle slide plate, another part then with cam contact; Its design feature is, described striking gear also comprises middle slide plate resetting means, and it to be positioned on the right side of middle slide plate and to be connected with camshaft bearing; Described tooth pitch adjusting device comprises support, rocking bar distance plate, screw mandrel, guide pillar and supporting plate; Described driving lever is connected on slide plate, and described rocking bar lower end is connected with middle slide plate by oscillating bearing, and upper end is connected with slide plate, and centre is then connected with rocking bar distance plate by oscillating bearing.
Further, described support is positioned at middle slide plate upper end and is connected with supporting plate, and described guide pillar and screw mandrel are assemblied between support and supporting plate, and described screw mandrel upper end is provided with a driver plate; Described rocking bar distance plate is arranged between support and supporting plate, itself and four guide pillar recessed bond ing, is fixedly connected with screw mandrel.
Compared with prior art, the beneficial effects of the utility model are, the utility model arranges tooth pitch adjusting device, fin tooth pitch are adjusted directly perceived simple.In addition the utility model adopts a cam and a camshaft bearing and slide plate resetting means in the middle of increasing by, and under resetting means spring-force driven dual, cam and camshaft bearing remain at surface contact state, add machine operation Stability and dependability.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is sled mechanism structural representation in the middle of the utility model.
Detailed description of the invention
By detailed the utility model technology contents, architectural feature, reached object and effect, below will exemplify embodiment and coordinate Figure of description to be described in detail.
Fig. 1 is the utility model structural representation, Fig. 2 is sled mechanism structural representation in the middle of the utility model, shown in Fig. 1 composition graphs 2, the utility model comprises striking gear and tooth pitch adjusting device, wherein, striking gear comprises middle slide plate 3, middle slide plate base 1, cam 6, rocking bar 11, driving lever 16 and slide plate 15, and tooth pitch adjusting device comprises support 8, rocking bar distance plate 9, screw mandrel 10, guide pillar 12 and supporting plate 13; Middle slide plate 3 lower end is connected with middle slide plate base 1 by line slideway 2; Cam 6 is positioned at middle slide plate 3, inside middle slide plate 3 right-hand member, be provided with camshaft bearing 5, and this camshaft bearing 5 part is placed in middle slide plate 3, and another part then contacts with cam 6; Described striking gear also comprises middle slide plate resetting means 4, and it to be positioned on the right side of middle slide plate 3 and to be connected with camshaft bearing 5.
When cam 6 rotates clockwise, middle slide plate 3 moves under camshaft bearing 5 acts on; Wherein when cam 6 is rotated to peak by minimum point with camshaft bearing 5 contact surface, middle slide plate 3 moves to the right, and when being rotated to minimum point by peak, moves to the left under the effect of middle slide plate 3 spring in middle slide plate resetting means 4; When cam 6 continues to rotate, middle slide plate 3 is done left and right and is repeatedly moved.
Continue with reference to shown in Fig. 1, rocking bar 11 is connected with slide plate 15, and it is connected by oscillating bearing 7 with rocking bar distance plate 9 and middle slide plate 3; Be connected with line slideway 2 between slide plate 15 with supporting plate 13, to ensure slide plate 15 smoothly movement; When cam 6 rotates, rocking bar 11 under middle slide plate 3 acts on the oscillating bearing 7 on rocking bar distance plate 9 for fulcrum swings, drive slide plate 15 moves left and right simultaneously; Driving lever 16 is connected on slide plate 15, when slide plate 15 moves left and right, drives driving lever 16 synchronously to move left and right, makes left and right displacement to drive other mechanism.
As shown in Figure 1, support 8 is positioned at middle slide plate 3 upper end and is connected with supporting plate 13; Guide pillar 12 and screw mandrel 10 are assemblied between support 8 and supporting plate 13; Rocking bar distance plate 9 is assemblied between support 8 and supporting plate 13, and matched in clearance made by itself and four guide pillars 12, and fixing with screw mandrel 10 is connected, and when the driver plate 14 be connected on screw mandrel 10 rotates, drives rocking bar distance plate 9 to move up and down.
When driving lever 16 need be changed stir spacing, adjustment rocking bar distance plate 9 upper-lower position, that is just can achieve the goal in change rocking bar 11 swing pivot position; Spacing stirred by driving lever 16 and rocking bar 11 swing pivot exists certain ratio, and stirring spacing directly can be checked by driver plate 14 high scale.
Content is only the preferred embodiment of the utility model in sum, does not limit the protection domain of the utility model patent with this.All equivalence changes done according to the utility model the scope of the claims and description with modify, within the scope all contained in the utility model patent.
