Abstract
In order to solve the problems that an existing vertical type needle-shaped impact grinding fixing pin structure is short in service life, needs to be replaced frequently, and is high in cost in the prior art, the utility model provides a vertical type needle-shaped impact grinding fixing pin structure. The vertical type needle-shaped impact grinding fixing pin structure is cylindrical, a screw hole is formed in the axial center, the upper end of a fixing pin, the lower end of the fixing pin and the screw hole are provided with counter bores in the same axis, and the fixing pin is fixed on a fixing disk through a countersunk screw. The vertical type needle-shaped impact grinding fixing pin structure has the advantages that installation is easy and convenient, the service life of the fixing pin is greatly prolonged, and usage cost of a user is reduced due to the fact that the fixing pin can be reversed and installed to be used when one end of the fixing pin is abraded to certain extent.
Description
Technical field
The utility model relates to a kind of vertical aciculiform impact grinding and decides needle construction.
Background technology
Vertical aciculiform impact grinding is a kind of aciculiform impact grinding that utilizes centrifugal force, it distributes raw material by the Moving plate of rotation, the material branch left and right sides enters the Moving plate center of rotation at a high speed, under powerful effect of centrifugal force fast to around distribute, and in working chamber, be subjected to the moving pin of rotation at a high speed and fixedly decide pin bump and fragmentation strongly repeatedly.It is cylindrical that needle construction is decided in vertical aciculiform impact grinding of the prior art and axial centre is provided with screw, decides the same axial line of pin lower end and screw and is provided with counterbore, will decide pin by sunk screw and be fixed on the price fixing.But because that the gravity of material and Moving plate face cone degree to the effect of material, cause deciding the counterbore end wearing and tearing of pin lower end is comparatively serious, have to often change decide pin, make user's cost increase.In a word, vertical aciculiform impact grinding of the prior art is decided needle construction and is existed service life shorter, needs often to change the cost problem of higher.
The utility model content
Decide needle construction and exist service life shorter for solving vertical aciculiform impact grinding of the prior art, need often to change the cost problem of higher.The utility model proposes a kind of vertical aciculiform impact grinding and decide needle construction.
It is cylindrical that needle construction is decided in the vertical aciculiform impact grinding of the utility model and axial centre is provided with screw, decides pin and up and down is equipped with counterbore on two ends and the same axial line of screw, decides pin and is fixed on the price fixing by sunk screw.
The beneficial effect that needle construction is decided in the vertical aciculiform impact grinding of the utility model is when deciding pin one end and may wear to a certain degree, can turn around to install and use with deciding pin, installation is simple like this, has prolonged the service life of deciding pin greatly, makes user's use cost be minimized.
Description of drawings
Fig. 1 is that the needle construction schematic diagram is decided in vertical aciculiform impact grinding in the prior art;
Fig. 2 is an A portion enlarged diagram among Fig. 1;
Fig. 3 is that the needle construction schematic diagram is decided in the vertical aciculiform impact grinding of the utility model;
Fig. 4 is a B portion enlarged diagram among Fig. 3.
Below in conjunction with drawings and the specific embodiments to the utility model vertical aciculiform impact grinding decide needle construction and be described further.
The specific embodiment
Fig. 1 is that the needle construction schematic diagram is decided in vertical aciculiform impact grinding in the prior art; Fig. 2 is an A portion enlarged diagram among Fig. 1.1 is screw, 2 for deciding pin, 3 is counterbore, 4 is sunk screw, 5 is price fixing, 6 be Moving plate as seen from the figure, it is cylindrical that needle construction is decided in vertical aciculiform impact grinding of the prior art and axial centre is provided with screw 1, decide pin 2 lower ends and screw 1 same axial line is provided with counterbore 3, will decide pin 2 by sunk screw 4 and be fixed on the price fixing 5.But because that the gravity of material and Moving plate 6 face cone degree to the effect of material, cause deciding the wearing and tearing of pin 2 lower end counterbores 3 ends is comparatively serious, have to often change decide pin 2, make user's cost increase.In a word, vertical aciculiform impact grinding of the prior art is decided needle construction and is existed service life shorter, needs often to change the cost problem of higher.
Fig. 2 is that the needle construction schematic diagram is decided in the vertical aciculiform impact grinding of the utility model; Fig. 4 is a B portion enlarged diagram among Fig. 3.7 is screw, and 8 for to decide pin, and 9 is counterbore, and 10 is sunk screw, and 11 is price fixing.As seen from the figure, it is cylindrical that needle construction is decided in the vertical aciculiform impact grinding of the utility model and axial centre is provided with screw 7, decides pin and is equipped with counterbore 9 on two ends and the screw 7 same axial lines about in the of 8, decides pin 8 and is fixed on the price fixing 11 by sunk screw 10.The vertical aciculiform impact grinding of the utility model is decided needle construction when deciding pin 8 one ends and may wear to a certain degree, can turn around to install and use with deciding pin 8, installs simplely like this, has prolonged the service life of deciding pin 8 greatly, makes user's use cost be minimized.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (1)
1. to decide needle construction be cylindrical and axial centre is provided with screw for a vertical aciculiform impact grinding, it is characterized in that: decide pin and be equipped with counterbore on two ends and the same axial line of screw up and down, decide pin and be fixed on the price fixing by sunk screw.
