Description
Technical field
The utility model relates to indexing mechanism technical field used in industrial production, in particular to a kind of precision round subsection
Mechanism.
Background technique
Indexing mechanism, especially index dial are the intermittent motion mechanisms in a kind of machinery field, are by the continuous of driving link
Conversion of motion is the mechanism for the cycle movement that driven member has interval.
Common mechanical dividing disk has with the movement of mouse dentition formula method, has with the movement of Worm-gear type method, also
Have with the movement of positioning pin method.These in the prior art, due to the demand of each component placement installation site, use space
Very big, mechanism is not compact, especially substrate with move etc. the distance between scoreboards it is larger, and due to the displacement of driving force
Bigger, precision just becomes lower and lower.Simultaneously as indexing mechanism carries out one-way movement except through driving mechanism, it can be with
Move back and forth, if substantially with etc. distance is larger between scoreboards, wait component efficiencies extremely low, precision cannot reach requirement.
Utility model content
The utility model provides a kind of precision round subsection mechanism, simple and compact for structure, and precision is easy calibration when installation, reaches
Efficient and high-precision mechanical equal part.
The utility model is realized through the following technical scheme:
A kind of precision round subsection mechanism, including substrate and etc. scoreboards, there is on the ontology of the scoreboards such as described locating slot, it is described
Substrate by central axis with it is described etc. scoreboards are parallel assembles, a driving motor is installed on the substrate bottom surface and described in passing through
Synchronous with the one sliding tooth wheel connection of the ontology of substrate, a synchronous driven gear be assemblied on the central axis and with the synchronous drive
Moving gear engages, and positioning pin is installed on the substrate and gos deep into the locating slot by a hydraulic pushing device or returns former
Position.
The hydraulic pushing device and the positioning pin are installed on the substrate by positioning pin cushion block.
The hydraulic pushing device includes a positional cylinder, and the piston being mounted on the positional cylinder releases oil
Road pipe and piston retract oil-way pipe and a cylinder piston rod installed with the positioning pin tail portion.
The positioning pin is rested under non-release state in a location key seat.
The inside of the locating slot has correction block.
The beneficial effects of the utility model are:
1. the utility model by the substrate of indexing mechanism with etc. the distance between scoreboards reduce, make the structure of the indexing mechanism
Simpler and compact, applicable range is more extensive.
2. passing through the adjustment of hydraulic-driven and structure, the precision of the indexing mechanism is higher.

Specific embodiment
Below in conjunction with above-mentioned attached drawing, the utility model is described further.
It is a kind of precision round subsection mechanism, such as Fig. 2 and Fig. 3 institute as shown in Figure 1, being the structural assembly figure of the utility model
Show, is demonstrated by its mounting means.The precision round subsection mechanism include substrate 1 and etc. scoreboards 2, have on the ontology of the scoreboards 2 such as described
Have a locating slot 3, substrate 1 by a central axis 14 with etc. scoreboards 2 are parallel assembles.As shown in Figure 3, etc. outside the centre bore of scoreboards 2
The scoreboards 2 such as edge has equal part plate core axis 12, and the pedestal and substrate 1 of central axis 14, which are stablized, to be installed, and the ontology of central axis 14 passes through
Centre bore make substrate 1 with etc. scoreboards 2 form parallel assembly relation, and the dress that bearing 13 and bearing lock nut 15 guarantee
The stability matched.One driving motor 21 is installed on the bottom surface of substrate 1 and passes through the ontology company of sliding tooth wheel 20 synchronous with one of substrate 1
It connects, a synchronous driven gear 18 is assemblied on central axis 14 and engages with synchronous driving gear 20, and synchronous toothed belt 19 is also protected
Driving and driven fastening and stability are demonstrate,proved.Positioning pin 5 is installed on substrate 1 and is deeply determined by a hydraulic pushing device
Position slot 3 returns in situ.
As shown in Fig. 2, this hydraulic pushing device and positioning pin 5 are installed on substrate 1 by positioning pin cushion block 16.This
Sample make positioning pin 5 with etc. scoreboards 2 be located at the same level height.Hydraulic pushing device includes a positional cylinder 7, and installation
Piston on positional cylinder 7 releases oil-way pipe 10 and piston retracts oil-way pipe 9 and one installed with 5 tail portion of positioning pin
Cylinder piston rod 6.In Fig. 2, positioning pin 5 is rested under non-release state in a location key seat 4.The inside of locating slot 3
With correction block 22.
At work, driving motor 21 is started, synchronous driving gear 20 drives synchronous driven tooth by synchronous toothed belt 19
Wheel 18, the scoreboards 2 such as driving rotate an angle, and the electric system of driving motor 21, which can control after it rotates an angle, to stop
Under, positioning pin 5 is under the driving of positional cylinder 7 at this time, by being forced into locating slot 3 for cylinder piston rod 6, by equal part
Plate 2 is accurately positioned.When etc. scoreboards 2 need to be rotated again when, hydraulic pushing device further works, positioning pin 5
Exit locating slot 3, at this time etc. scoreboards 2 start to continue to rotate an angle, and so on realize that duplicate indexing positions.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
