Abstract

The utility model provides a machinery cutter head with blind rivet floats, including base member and a plurality of blind rivets of setting on its surface, the blind rivet place set up in in the blind rivet mounting hole of matrix surface blind rivet mounting hole median septum, with set up the dish spring in its bottom the blind rivet sets up the baffle upside the outside cover of blind rivet is equipped with apron and lock nut. The utility model discloses a thereby the setting has certain fault -tolerant space at the baffle of blind rivet bottom with the reservation of dish spring, can improve the adaptability of product, and increase of service life reduces the maintenance maintenance cost.

Description

With the mechanical milling head of floating blind rivet

Technical field

The utility model relates to a kind of mechanical milling head, especially a kind of mechanical milling head with floating blind rivet.

Background technology

At present, the mechanical milling head of domestic machine industry application, the overwhelming majority adopts the mode of blind rivet+oil cylinder. and be generally that 4 oil cylinders are built in ram four angles place, on milling head, correspondence position installs 4 blind rivets.During work, after 4 blind rivets aim at 4 corresponding oil cylinder positions, blind rivet is strained by the disc spring force provided by oil cylinder.The operation principle of oil cylinder blind rivet is not the content that the present invention discusses, therefore is not repeated herein.

But due to the error of processing and manufacturing, the position of 4 corresponding 4 oil cylinders of blind rivet can not error be zero, sometimes even larger, there will be the phenomenon breaking blind rivet.Or although blind rivet strained by oil cylinder, because position misaligns, the radial load causing wherein one to two blind rivets not should bear, not only affects installation and debugging precision, after milling head uses a period of time, also may occur that destruction oil cylinder causes the situation of leakage of oil etc.

Summary of the invention

For the weak point existed in the problems referred to above, the utility model provides a kind of and is reserved with certain fault tolerant workspace, can improve the adaptability of product, increase the service life, and reduces the mechanical milling head with floating blind rivet of maintenance maintenance cost.

For achieving the above object, the utility model provides a kind of mechanical milling head with floating blind rivet, comprise matrix (1) and be arranged on multiple blind rivets (2) on its surface, described blind rivet (2) is placed in the blind rivet installing hole being opened in described matrix (1) surface, described blind rivet installing hole median septum (6), be arranged on disc spring (5) bottom it, be arranged on described dividing plate (6) upside at described blind rivet (2), be arranged with cover plate (3) and locking nut (4) in the outside of described blind rivet (2).

The above-mentioned mechanical milling head with floating blind rivet, wherein, the diameter being opened in the interstitial hole on described cover plate (3) is greater than the diameter of described blind rivet (2).

The above-mentioned mechanical milling head with floating blind rivet, wherein, described disc spring is not when stressing, and the position of described cover plate (3) should higher than the upper surface of described matrix (1).

The above-mentioned mechanical milling head with floating blind rivet, wherein, described locking nut (4) is set in the bottom of described blind rivet (2).

Compared with prior art, the utility model has the following advantages:

The utility model, by being arranged on dividing plate bottom blind rivet and disc spring thus being reserved with certain fault tolerant workspace, can improve the adaptability of product, increase the service life, reduce maintenance maintenance cost.

Fig. 1 is structure chart of the present utility model.

Main Reference Numerals is described as follows:

1-matrix; 2-blind rivet; 3-cover plate; 4-locking nut; 5-disc spring; 6-dividing plate

Detailed description of the invention

As shown in Figure 1, the utility model provides a kind of mechanical milling head with floating blind rivet, comprise matrix 1 and be arranged on multiple blind rivets 2 on its surface, blind rivet 2 is placed in the blind rivet installing hole being opened in matrix 1 surface, blind rivet installing hole median septum 6, be arranged on disc spring 5 bottom it, be arranged on the upside of dividing plate 6 at blind rivet 2, be arranged with cover plate 3 and locking nut 4 in the outside of blind rivet 2.Locking nut 4 is set in the bottom of blind rivet 2.

The diameter being opened in the interstitial hole on cover plate 3 is greater than the diameter of blind rivet 2.Wherein, the diameter of the interstitial hole of cover plate 3 2mm larger than blind rivet journal diameter portion.

Disc spring is not when stressing, and the position of cover plate 3 should higher than the upper surface of matrix 1, and wherein, the position of cover plate 3 is higher than the upper surface 1mm of matrix 1.

Assemble flow of the present utility model is as follows:

Disc spring is put into the blind rivet installing hole that matrix surface is offered, put into dividing plate at the top surface of disc spring; Cover plate and locking nut are set in after on blind rivet, blind rivet are placed in blind rivet installing hole, and be placed on above dividing plate; Screw is adopted to be fixed on matrix by cover plate, by disc spring being compressed with the pulling force of screw, to produce lasting elastic force.

Disc spring is arranged on the below of blind rivet, makes blind rivet have elasticity, its franchise is ± 1mm, and allows angle to have certain deviation, and finally all because float reason, blind rivet self will find most suitable position to be fixed.

The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
