Description
Technical field
The utility model belongs to screen door in rail transit process units field, is used for rail traffic screen more particularly to one kind
Cover the positioning pusher dog of a process units.
Background technique
Pusher dog is one of most common product material toggling part in automation equipment such as screen door in rail transit process units, main
Product feeding, the positioning being used in screen door in rail transit production, it is all to pass through list that conventional art pusher dog, which does not have dual contact,
Side contact product carries out feeding, leads to feeding inaccuracy, offset, debugs in production process complicated, it is also necessary to individually be equipped with product
Positioning mechanism leads to design complexity, cost increase, and is easy to damaged products.
Utility model content
The purpose of this utility model is that: in order to overcome the deficiencies of the prior art, provide a kind of for screen door in rail transit
The positioning pusher dog of process units.The utility model is simple, and processing technology is simple, and stability is good, good positioning effect, and produces
It is at low cost.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of positioning pusher dog for screen door in rail transit process units, it is characterised in that: described including pusher dog ontology
Step surface and mounting surface are offered on pusher dog ontology, the mounting surface is equipped with front and back positioning card, opens up on the pusher dog ontology
There are mounting hole and two dowel holes, mounting hole is located between two dowel holes, pusher dog slot is offered on the pusher dog ontology,
Pusher dog slot two sides offer positioning surface one and positioning surface two respectively, and guide surface one is offered on the positioning surface one, positioning
Guide surface two is offered on face two, it is described to offer the angle C one on the pusher dog ontology of positioning surface one, positioned at dialling for positioning surface two
The angle C two is offered on pawl ontology.
The angle C in the angle C one and the angle C two refers to 45 ° of chamferings.
As the above scheme is adopted, the utility model has the beneficial effects that:
1, the utility model uses and offers step surface and mounting surface on the pusher dog ontology, before the mounting surface is equipped with
Positioning card afterwards offers mounting hole and two dowel holes on the pusher dog ontology, and mounting hole is located between two dowel holes,
Pusher dog slot is offered on the pusher dog ontology, pusher dog slot two sides offer positioning surface one and positioning surface two respectively, described fixed
Guide surface one is offered on plane one, and guide surface two is offered on positioning surface two, it is described on the pusher dog ontology of positioning surface one
The angle C one is offered, offers the angle C two on the pusher dog ontology of positioning surface two；Structure is simple, and design is simple, and stability is good, resistance to
Abrasion, good positioning effect.
2, the structure of the utility model is applied in screen door in rail transit production technology, and not only plant maintenance is simple, also
Substantially increase production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference: 1- pusher dog ontology, 2- step surface, 3- mounting surface, the front and back 4- positioning card, 5- dowel hole, 6- installation
Hole, 7- positioning surface one, 8- guide surface one, 9- pusher dog slot, 10- positioning surface two, 11- guide surface two, the angle 12-C one, the angle 13-C two.
Specific embodiment
The utility model is further detailed with reference to the accompanying drawings of the specification:
Embodiment 1
A kind of positioning pusher dog for screen door in rail transit process units, including pusher dog ontology 1, the pusher dog ontology 1
On offer step surface 2 and mounting surface 3, the mounting surface 3 is equipped with front and back positioning card 4, offers peace on the pusher dog ontology 1
Hole 6 and two dowel holes 5 are filled, mounting hole 6 is located between two dowel holes 5, offers pusher dog slot on the pusher dog ontology 1
9, the two sides of the pusher dog slot 9 offer positioning surface 1 and positioning surface 2 10 respectively, offer guiding on the positioning surface 1
Face 1 offers guide surface 2 11 on positioning surface 2 10, described to offer the angle C one on the pusher dog ontology 1 of positioning surface 1
12, the angle C 2 13 is offered on the pusher dog ontology 1 of positioning surface 2 10.
When the present embodiment is in use, the surface smoothness of the pusher dog slot 9, positioning surface 1 and positioning surface 2 10 is
Ra0.8.The pusher dog ontology 1 is using SKD11, and HRC56 material is made.
The utility model is not limited to the above embodiments, within the spirit and principle of the utility model, made any
Modification, equivalent replacement, improvement etc., should be included within the scope of protection of this utility model.
