Description

A kind of flinger

Technical field

The utility model relates to a kind of flinger of shot-blasting machine.

Background technology

Flinger (ramming head) ramming head is the host part of shot-blasting machine, its effect is to parts to be processed with the shot high-speed projectile, make parts surface produce required matsurface or special performance, reach the surface-treated effect, also comprise eliminate rust, cleaning, light decorations, reinforcement and surface stress processing etc.And be used for the processing of various components of machine.The structure more complicated of existing shot-blasting machine flinger ramming head, especially the distance of the transmission between motor and the flinger is big, ball blast transport also more complicated of channels designs, therefore, the requirement power of electric motor is big, indexs such as mean time between failures are affected, and this just needs the flinger of widely applicable shot-blasting machine.

The utility model content

The utility model purpose will overcome above-mentioned shortcoming exactly, and a kind of flinger of shot-blasting machine of new construction is provided; The purpose of this utility model is achieved in that the flinger of shot-blasting machine of the present utility model, by motor 1, motor flange 20, import tube 3, ramming head lid 10, distributor 14, impeller 29, blade 32, casing liner 33, blade groove 34, orienting cover 35 constitutes, be provided with motor flange 20 and fix 1 with motor shaft, fixedly connected ball blast distributor 14 on the motor flange 20, the orienting cover 35 of the central tubular that is provided with is contained in the position that the flange axis prolongs, impeller 29 is made of two plate-like disks, the axle that is provided with between two plate-like disks with the orienting cover 35 of central tubular is the blade 32 of the center of circle in radius distribution, the centre of blade 32 has blade groove 34, be provided with between two plate-like disks at equally distributed connecting rod 31 of disk week, be provided with ball blast and import the orienting cover 35 that tube 3 is connected to the central tubular in flange axle center, import tube and connect orienting cover 35 at the central part of impeller 29, install on the equally distributed gap of circumference on the orienting cover 35 and be provided with orifice plate shape distributor 14, the plate hole of distributor 14 is communicated to blade groove 34.

Referring to Fig. 1 side cutaway view: shot enters ramming head by the arrow A place, impeller 34 rotations via driven by motor, ball blast (shot) is by in the orienting cover 35 that imports the tube 3 inputs central tubular identical with the flange axis, shot is provided with orifice plate shape distributor 14 by installing on the equally distributed gap of circumference on the orienting cover 35, and the plate hole of distributor 14 is communicated to blade groove 34 and shot is carried so far.Like this, blade groove goes out the shot high velocity jet.It is fan-shaped that spray angle becomes.

The utility model has the advantages that: the utility model is a kind of flinger (ramming head) structure of shot-blasting machine of compact conformation, motor and flinger organically combine, and functional reliability is good, and on average even time between failures is long, and maintenance and replacing wearing terrain are convenient and swift.
