Abstract
The utility model discloses a kind of electronic dobby machine pulling hook connecting structure, belong to dobbies auxiliary equipment field.Serious wear, the defect of short life that existing Multi arm machine pulling hook connecting structure is present.The utility model includes connecting plate and the drag hook being connected in by mandrel on connecting plate, plasticity bushing is cased with mandrel, the axis hole being coupled with mandrel is opened up on drag hook, mandrel is fixed on connecting plate, plasticity bushing is fastened in axis hole, described shaft hole inner wall is provided with translot, the side wall insertion of translot and axis hole.The utility model, so as to operationally by the deformation of plasticity bushing, increase contact surface, reduces the load in unit area by being arranged plasticity bushing on the rotation section of mandrel, reduces abrasion, extends the life-span；Simple structure, it is easy to implement.
Description
Technical field
The utility model belongs to dobbies auxiliary equipment field, especially has with a kind of electronic dobby machine pulling hook connecting structure
Close.
Background technology
On dobbies, drag hook is coupled with connecting plate using mandrel, and ream machining goes out and matches somebody with somebody with shaft core gap on drag hook
The axis hole of conjunction, produces alternating pressure load between axis hole and shaft core during work.Drag hook working pulling force is about 1000N, mandrel and drawing
The contact surface of hook axis hole is distributed only in the range of about the 1/100 of whole endoporus circumference, drag hook axis hole and shaft core surface contact load
200Mpa is reached, causes local by tension and compression during work, abrasion is quite serious, is in ellipticity, working life after the work of drag hook axis hole
Greatly reduce.
Utility model content
The purpose of this utility model seeks to solve serious wear, longevity that existing electronic dobby machine pulling hook connecting structure is present
The short defect of life, there is provided a kind of long service life, anti abrasive electronic dobby machine pulling hook connecting structure.
Therefore, the utility model takes following technical proposals：A kind of electronic dobby machine pulling hook connecting structure, including connecting plate
With the drag hook being connected in by mandrel on connecting plate, it is characterized in that, plasticity bushing is cased with described mandrel, opened on described drag hook
If the axis hole being coupled with mandrel, described mandrel is fixed on connecting plate, described plasticity bushing is fastened in axis hole, described
Shaft hole inner wall be provided with translot, the side wall insertion of translot and axis hole.
During utility model works, mandrel is fixed on connecting plate and is rotated relative to drag hook, and plasticity bushing is to be set in mandrel
The rotation section；When being squeezed, plasticity bushing is deformed, and increases contact surface, reduces the load in unit area, reduces mill
Damage, extend the life-span.
Following beneficial effect can be reached using the utility model：The utility model is arranged by the rotation section of mandrel
Plasticity bushing, so as to operationally by the deformation of plasticity bushing, increase contact surface, reduces the load in unit area, reduces
Abrasion, extends the life-span；Simple structure, it is easy to implement.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes connecting plate 3 and the drag hook 1 being connected in by mandrel 5 on connecting plate 3, on mandrel
Plasticity bushing 2 is cased with, the axis hole being coupled with mandrel 5 is opened up on drag hook 1, mandrel 5 is fixed on connecting plate 3, and plasticity bushing 2 is tight
Gu in axis hole, shaft hole inner wall is provided with translot 4, the side wall insertion of translot 4 and axis hole, between nylon plasticity bushing 2 and mandrel 5
Certain gap is kept, is easy to mandrel 5 to be rotated in nylon bush 2.During utility model works, plasticity bushing 2 is squeezed product
Change shape, increases the contact area between mandrel 5 and plasticity bushing 2, contact load is reduced to 12Mpa, while increased
Wear resistence, operating lifetime was reached as high as 25000 hours by more than 10000 hours.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
