Abstract
The utility model belongs to valve location mechanism. A special angle location mechanism comprises an inching switch and a location disk. The utility model is characterized in that: the location disk is divided into two layers, one is the basic layer of which the margin is provided with a location groove, the other is a sliding layer mounted in the basic layer and a location axis is fixed on the basic layer of the location disk. The utility model has the advantages that: the production and assembly processes are very simple: firstly, rotating the location axis 5 to the required angle, then aligning the basic location groove to the switch convex button and fixing the basic layer and axis. The utility model can be assembled just as required without any adjusting process, and is convenient for mass production and assembly.
Description
Technical field
The utility model belongs to the valve positioning means.
Background technique
Existing valve positioning means, it mostly is cam mechanism, as shown in Figure 1, positioning requirements for the several angle position of positioning shaft 5, be just in time to contact on convex twisting 2 edges of sensitive switch 1 by the edge that makes the positioning disk cam 4 on the positioning disk 3 to realize, in fact we in advance and the convex arc of not knowing cam 4 actually any point just make sensitive switch convex twisting 2 actions, can only be when therefore producing by the debugging decision, thereby its shortcoming is to produce debugging to install inconvenient, each all needs careful adjustment, is not suitable for producing in batches or using.
The model utility content
The purpose of this utility model is to overcome the defective of prior art, and a kind of special angular positioning mechanism is provided, and the technical solution of the utility model is:
A kind of special angular positioning mechanism comprises sensitive switch and positioning disk, and it is characterized in that: positioning disk is divided into two-layer, and one deck is the basic layer that the edge is provided with the basic fixed position groove; Another layer is for being embedded in the sliding layer in the basic layer, and positioning shaft is fixed on the basic layer of positioning disk.
Beneficial effect is: so we are very simple in the production assembly process, at first make positioning shaft 5 forward desired orientation angle to, make the convex twisting of basic fixed position groove alignment sensitive switch then, and make the basic layer and fastening the getting final product of axle of positioning disk, so there is not the process of debugging in this kind method, directly assembling gets final product on request, makes things convenient for the production assembling of typical products in mass production.
Description of drawings
Fig. 1 is the valve positioning means structural representation of prior art, wherein, and 1 sensitive switch, 2 sensitive switch convex twistings, 3 positioning disks, 4 positioning disk cams, 5 positioning shafts.
Fig. 2 is the utility model structural representation, wherein, and 1 sensitive switch, 2 sensitive switch convex twistings, 3 positioning disks, 4 grooves, 5 positioning shafts.
Fig. 3 is a kind of embodiment's of the utility model a structural representation, wherein, and 1 sensitive switch, 2 sensitive switch convex twistings, 5 positioning shafts, the basic layer of 30 positioning disks, 31 basic fixed position grooves, 300 sliding layers.
Fig. 4 is the exploded view of Fig. 3, wherein, and 5 positioning shafts, 11 baffle plates, 12,13 slide blocks, 14,15 springs, 17,16 baffle plates, the basic layer of 30 positioning disks, 31 basic fixed position grooves, 32 sliding recess, 36 lead angles, 2,37 lead angles, 1,40 sliding recess width, 41 basic fixed position recess width.
Embodiment
Referring to accompanying drawing 2, special angular positioning mechanism comprises sensitive switch 1 and positioning disk 3, and positioning shaft 5 is fixed on the positioning disk 3, is provided with a groove 4 on positioning disk 3, and its size and shape is just in time corresponding to sensitive switch convex twisting 2.
In actual use, for accurate positioning, we wish that the angle, inside edge of groove is steep, but for making cam skid off groove easily, we wish angle, the inside edge slyness of groove again, and in order to reach this two purposes simultaneously, the mode of execution an of the best as shown in Figure 3.
As seen from Figure 3: a kind of special angular positioning mechanism, comprise sensitive switch 1 and positioning disk, the 2nd, the sensitive switch convex twisting, positioning disk is divided into two-layer, and one deck is the basic layer 30 that the edge is provided with basic fixed position groove 31; Another layer is for being embedded in the sliding layer 300 in the basic layer of positioning disk, and positioning shaft 5 is fixed on the basic layer of positioning disk.
Fig. 4 decomposes Fig. 3, therefrom can see: sliding layer is made up of slide block 12,13, and is adjacent to baffle plate 11 under spring 14,15 effects, and its symmetric arrangement also forms sliding recess 32, and spring one end promotes slide block, and the other end and baffle plate 17,16 offset.Basic fixed position groove 31 has big fillet 36, so the convex twisting on the sensitive switch 1 skids off easily, sliding recess 32 has sharper fillet (being lead angle 1) 37, has guaranteed the accuracy of angular orientation when convex twisting slips into sliding recess 32 on the sensitive switch 1, and then has guaranteed accurate positioning.So basic fixed position recess width 41 sizes are greater than sliding recess width dimensions 40; And slick and sly many in 36 angles, edge, the edge of basic fixed position groove (being angle lead angle 2) (being angle lead angle 1) 37 than sliding recess.
By Fig. 3, Fig. 4 as can be seen positioning disk near locating notch near the time, positioning disk is divided into two-layer: the basic layer 30 of positioning disk, with the sliding layer 300 that is embedded in the basic layer of positioning disk, the basic layer of positioning disk has a basic fixed position groove 31; When required positioning rotating shaft 5 rotates, driving positioning disk rotates together, the surface of sensitive switch 1 is close to positioning disk and is slided, the convex twisting 2 of the sensitive switch 1 basic layer 30 of dish that is positioned is depressed, and maintenance depressed state, along with positioning disk rotates, when convex twisting 2 during near basic fixed position groove 31 and sliding recess 32, if there is not sliding recess 32, convex twisting will spring among the basic fixed position groove 31, less because of sliding recess 32 width of rebate, the angle, edge is also little, and convex twisting this moment will be supported by slide block 12 or 13, only be rotated further, when convex twisting during near sliding recess 32 centers, convex twisting just can be ejected, and extruding slide block 12,13 to two side shiftings, convex twisting 33 this moment just has certain clearance from basic fixed position groove 31 both sides, this is because the cause of basic fixed position groove 31 broads, and what this had solved simultaneously also that the rotating shaft resilience causes is pressed into action again to sensitive switch.
When rotating shaft is rotated further, because angle, sliding recess 32 edge is more steep, convex twisting will be blocked slide block 12 or 13 and promote the spring slip together, when convex twisting slides into basic fixed position groove 31, because basic fixed position groove 31 edges are comparatively slick and sly, convex twisting will skid off basic fixed position groove 31, and convex twisting will be pressed into, and continue to slide along basic layer 30.
