Abstract
The utility model discloses a fixed structure of electromechanical column round pin and rubber circle is attacked to brill, include motor output shaft and I axle, through last coupling band, pin and second line of a couplet shaft liner connection between motor output shaft and the I axle, the lower pinhole of coupling band up end is connected under going up the coupling band and reaching through the last pinhole on the last coupling band bottom face, pin between the coupling band down to the pin part outer lane that is located the pinhole is equipped with the rubber circle, being equipped with protruding ring on the rubber circle inner wall, being equipped with the recess with the corresponding pin of this protruding ring on the rubber circle inner wall, the protruding ring gomphosis on the rubber circle inner wall is in the pin recess. The utility model discloses enclose inner wall part design with rubber and be protruding ring, correspondingly with it design into the recess with the pin part, the gomphosis that rubber circle and recess can be tightly when installing so together, the rubber circle can not drop easily, when the pin carry -over moment, torque transmission's stability also can be guaranteed to this kind of structure simultaneously, and then increases to bore and attack quick -witted driven reliability.
Description
Technical field
The utility model relates to the fixed structure that a kind of brill attacks dynamo-electric column pin and rubber ring, belongs to drilling machine technical field.
Background technique
Vertical drilling machine, as the one of drilling machine, is also more common metal-cutting machine tool, is widely used, and the feature that precision is high is suitable for batch process, is usually used in the hole of machine-building and the medium and small workpiece of repair factory process.Be rigidly connected owing to adopting between the motor output shaft of existing vertical drilling machine and I axle, when the frequent clockwise and anticlockwise of motor, often can cause the fracture of I axle.For this kind of situation; claimant devises a kind of linkage structure adopting coupling band, pin, rubber ring and lower coupling band to be used as between motor output shaft and I axle; this kind of structure can be good at the breakage problem solving aforementioned I axle; but due to the outer surface being enclosed within pin that rubber ring is only level and smooth; often can cause coming off of rubber ring when mounted, and also certain influence is had to the stability of carry-over moment.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of brill to attack the fixed structure of dynamo-electric column pin and rubber ring, and when can solve installation, rubber ring easily comes off, and the defect that carry-over moment is stable, has structure simple, the advantage of successful.
The technical solution of the utility model: the fixed structure of dynamo-electric column pin and rubber ring attacked by a kind of brill, comprise motor output shaft and I axle, by upper coupling band between motor output shaft and I axle, pin is connected with lower coupling band, by the upper pin-and-hole on upper coupling band bottom end between upper coupling band and lower coupling band, the lower pin-and-hole of pin and lower coupling band upper-end surface connects, and the pin part outer ring being positioned at pin-and-hole is provided with rubber ring, described rubber ring inwall is provided with protruding ring, the pin corresponding with this protruding ring on rubber ring inwall is provided with groove, protruding ring on rubber ring inwall is entrenched in pin groove.
As preferably, the protruding ring on described rubber ring inwall has 2.
As preferably, the groove on described pin has 2.
As preferably, the upper pin-and-hole of described upper coupling band bottom end is 6, is evenly arranged in the bottom of coupling band.
As preferably, the lower pin-and-hole of described lower coupling band upper-end surface is 6, is evenly arranged in the upper-end surface of lower coupling band.
The beneficial effects of the utility model:
The design of rubber ring inner wall section is protruding ring by the utility model, what correspond becomes groove by pin partial design, protruding ring can be chimeric with groove, during such installation, rubber ring and groove can tightly be entrenched togather, rubber ring can not come off easily, simultaneously when pin carry-over moment, this kind of structure also can ensure the stability that moment is transmitted, and then increases the reliability of boring and attacking machine transmission.

Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
Composition graphs 1 to Fig. 7, the present embodiment bores the fixed structure of attacking dynamo-electric column pin and rubber ring, comprise motor output shaft 1, I axle 2, upper coupling band 3, pin 5 and lower coupling band 6, pin-and-hole 31 on 6 is offered at upper coupling band 3 bottom end, it is evenly arranged in the bottom of coupling band 3, offer 6 the lower pin-and-holes 61 corresponding with upper coupling band 3 in lower coupling band 6 upper-end surface, be also evenly arranged in the upper-end surface of lower coupling band 6.Above during installation to be connected by the lower pin-and-hole 61 of the upper pin-and-hole 31 on upper coupling band 3 bottom end, pin 5 and lower coupling band 6 upper-end surface between coupling band 3 with lower coupling band 6, and the pin 5 part outer ring sleeve being positioned at pin-and-hole 31 has rubber ring 4.
On rubber ring 4 inwall, offer 2 protruding rings 41 during manufacture, the pin 5 corresponding with this protruding ring 41 on rubber ring 4 inwall offers 2 grooves 51 in correspondent section, and aforementioned protruding ring 41 can be entrenched in groove 51.In order to easily manufactured, also on pin 5, this kind of structure can be obtained by curing rubber.
Adopt key to be connected between motor output shaft 1 with upper coupling band 3 in the utility model, lower coupling band 6 is connected with also adopting key between I axle 2.
