The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.Wherein, identical parts adopt identical label.
As shown in Figure 1, bulb rotary index device of the present utility model cooperates installation with the bulb 12 of X line machine, and this device comprises that 14, one bulbs 12 of support that are connected on the bulb 12 can be around the rotating shaft 16 of its rotation.When the needs oblique line was taken the photograph sheet, bulb 12 and support 14 can turn to suitable angle around rotating shaft 16 together.Cover is fixed with not rotatable index dial 26 on the rotating shaft 16, has a plurality of stopper slots 24 on the index dial 26.
In working order down, taper pin 22 inserts in the stopper slot 24 of index dial 26, to stablize the operating position of bulb 12.Taper pin 22 is arranged on the pull bar 34, and an end of pull bar 34 links to each other with support 14 by rotating shaft 32, in concrete embodiment, pull bar 34 promptly can directly link to each other with support 14, also can link to each other with support 14 via guide type shoe 38 as shown in Figure 1, guide type shoe is arranged on the support 14.Pulling pull bar 34 can drive pull bar 34 32 rotating certain angle around the shaft.Pull bar 32 can any suitable manner spur, and for example adopts mode shown in Figure 1, and a handle 42 is set, and handle 42 is connected by a rigidity rope 44 with pull bar 32, and turning handle 42 can spur pull bar 34.As shown in the figure, the guide type shoe 38 that links to each other with support 14 is provided with an elastic component 36, and the other end of elastic component 36 is connected on the pull bar 34.
The sketch map of a kind of embodiment of the rotary index device that Fig. 2 and Fig. 3 have illustrated.As shown in Figure 3, pull bar 134 wherein is " U " shape, and two ends of pull bar 134 " U " shape connect extension spring 136 and rigidity rope 44 respectively.When the bulb machine is in running order, in the stopper slot of the distribution 22 insertion index dials 26 that link to each other with pull bar 134 (being that drawing is succinct, not shown stopper slot).Rotating shaft 32 links together guide type shoe 138 and pull bar 134.The end of one end cylinder lever connecting rod 134 of elastic component 136, the other end is connected on the guide type shoe 38.
Referring to Fig. 3, when the angle of needs change bulb is taken the photograph sheet to carry out oblique line, operator's rotary handle (referring to Fig. 1), pulling rigidity rope 44, and then drive pull bar 134 32 rotations around the shaft.At this moment the taper pin 22 that is arranged on the pull bar 134 also rotates around rotating shaft 32, and distribution 22 is withdrawed from from a stopper slot (not shown) of index dial 26.
For example in a kind of concrete rotary index device, index dial 26 is provided with a stopper slot every 15 °, and taper pin 22 only need move 8 millimeters can withdraw from a stopper slot.After taper pin 22 withdrawed from stopper slot, index dial 26 was separated with support 14, and like this, support 14 and bulb are no longer locked, and can turn to around rotating shaft 16 and take the photograph the sheet desired location.When stopper slot was withdrawed from pull bar 134 rotation drive distributions 22, pull bar 134 was stretched extension spring 136.
After bulb rotate in place, operator's release handle, pull bar 134 no longer is subjected to pulling force, and at this moment the elastic restoring force of the extension spring 136 of tension turns back to position shown in Figure 2 with pushing drawing rod 134, and taper pin 22 can slip into wherein along the stopper slot outer slope centering of index dial 26.
For making rotary index device have higher positioning accuracy, taper pin 22 can adopt the design of bipyramid face, like this, the head of taper pin 22 can automatically reset under the resilient force of extension spring 136 and enter in the stopper slot, finishes location action.Because the conical surface angle of taper pin 22 is the conelet face design through calculating, make frictional force that the radially normal pressure of taper pin 22 produces greater than tangential withdrawal force, can obtain the effect of bidirectional self-locking, realize not having the gap, location, and taper pin 22 wearing and tearing backs can compensate under extension spring 136 effects automatically, even life-time service, rotary index device still can keep very high repetitive positioning accuracy.
Pull bar can be any suitable shape, and in the specific embodiment shown in Fig. 2 and 3, pull bar is " U " type, and in another kind of example as shown in Figure 4 and Figure 5, pull bar also can be " L " shape.
As shown in the figure, pull bar 234 wherein is " L " shape, and an end of pull bar 134 " L " shape connects compression spring 236 and rigidity rope 44 simultaneously.The end of one end cylinder lever connecting rod 234 of compression spring 236, the other end is connected on the guide type shoe 238.
Referring to Fig. 5, when the angle of needs change bulb is taken the photograph sheet to carry out oblique line, operator's rotary handle (referring to Fig. 1), pulling rigidity rope 44, and then drive pull bar 234 32 rotations around the shaft.At this moment the taper pin 22 that is arranged on the pull bar 234 also rotates around rotating shaft 32, and distribution 22 is withdrawed from from a stopper slot (not shown) of index dial 26.Pull bar 234 is stretched compression spring 236 simultaneously.
After bulb rotate in place, operator's release handle, pull bar 234 no longer is subjected to pulling force, and at this moment the elastic restoring force of the compression spring 236 of pressurized turns back to position shown in Figure 4 with pushing drawing rod 234, and taper pin 22 can slip into wherein along the stopper slot outer slope centering of index dial 26.
As mentioned above, bulb rotary index device of the present utility model, the mechanism that adopts a cover to be made up of pull bar, elastic component etc. has avoided standard setting pin internal clearance to the influence that the calibration positioning accuracy produces, and realizes location, no gap and high-precision resetting.And utilized lever principle when drive promoting by pull bar, the operator only needs very little power to get final product complete operation, simultaneously, can utilize the thrust of elastic component, the location centering time when bulb rotates has been saved in effective location that contacts between the conical surface that keeps taper pin and the stopper slot of index dial.
The above only is the schematic specific embodiment of this utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations, the modification of being done under the prerequisite that does not break away from design of the present utility model and principle and combining all should belong to the scope of this utility model protection.
