Specific embodiment
The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.
As shown in Figures 1 to 4, a kind of hollow grinding head described in the utility model, including grinding head main body 30 and cladding
Outer grinding layer 3 in 30 outer surface of grinding head main body.Traditional grinding head overall structure is divided into grinding head master by the utility model
Body 30 and outer grinding layer 3, are effectively transformed convenient for the structure to grinding head main body 30, realize that the utility model mitigates grinding head
Overall weight saves the technical purpose of materials'use.
The grinding head main body 30 includes the cooperate upper inner core 1 and lower inner core 2 of connection, the upper inner core 1 and lower interior
It is hollow that sealing is formed between core 2.Specifically, the grinding head main body 30 includes upper inner core 1 and lower inner core 2, the upper inner core 1
The cavity 13 of lower ending opening is inside formed, the lower interference fit of inner core 2 is arranged in the lower ending opening of cavity 13, described lower interior
2 upper end of core and formation sealing within 13 inner wall of cavity are hollow.The hollow size of the sealing can be according to upper inner core 1 and lower inner core
Material selected by 2, the factors such as intensity size specifically adjust, and under the premise of intensity is enough, it is hollow can to increase sealing as far as possible
Volume, with it is maximum can with mitigation grinding head weight, materials'use is saved, to finally realize the mesh for reducing production cost
's.
3 outer surface of outer grinding layer forms several shape of threads convex ribs 31, the upper inner core 1 or 3 top of outer grinding layer
Equipped with upper positioning region 11 (can be locating shaft or location hole, referring to fig. 2 and Fig. 5), the lower inner core 2 or 3 lower end of outer grinding layer
Equipped with lower positioning region 23 (can be locating shaft or location hole, referring to fig. 2 and Fig. 5).That is, when outer grinding layer 3 is uncoated
When upper 1 top of inner core, upper positioning region 11 is set to the Xiang Duan of upper inner core 1, and when outer grinding layer 3 is coated on 1 top of inner core, on
Positioning region 11 can be then directly arranged on outer grinding layer 3.Similarly, lower fixed when outer grinding layer 3 is uncoated when lower 2 lower end of inner core
Position portion 23 is set to the lower end of lower inner core 2, and when outer grinding layer 3 is coated on lower 2 lower end of inner core, lower positioning region 23 then can directly be set
In on outer grinding layer 3.
In addition, the inner wall of the lower positioning region 23 is equipped with non-metallic wear resistant layer 24.Because lower positioning region 23 directly with driving
The main shaft of motor connects, so the setting of non-metallic wear resistant layer 24, can raising wearability greatly, extend product uses the longevity
Life.
The lower inner core 2 includes clamping portion 21 and the stage portion 22 set on 21 bottom end of clamping portion；The clamping portion 21 is protruded into
In the lower ending opening of cavity 13, the lower end edge 12 of the upper inner core 1, which is supported, to be set in stage portion 22.In this way, the upper inner core 1
It is formed with lower inner core 2 good fit, lower inner core 2 is avoided excessively to protrude into cavity 13 under the effect of the pressure, influence to grind greatest service
The realization of energy.
The upper positioning region 11, lower positioning region 23 are on the center line of cavity 13.In this way, it is possible to prevente effectively from
Hollow grinding head described in the utility model swings when rotated.
The cap-like structure that the clamping portion 21 of the lower inner core 2 and stage portion 22 are integrally formed, the lower positioning region 23 at
Type is on cap-like structure inner roof wall.In this way, can further mitigate the weight of the utility model, material is saved, cost is reduced.
More specifically, the production method of a kind of hollow grinding head described in the utility model, includes the following steps:
1) POM, nylon or metal are selected, inner core 1 and lower inner core 2 are molded；Certainly, on the utility model
Core 1 and lower inner core 2 are not limited to above-mentioned making material, and other intensity are high, are conducive to molding plastic material or alloy material is equal
It can.
2) upper end of the lower ending opening inner wall of the cavity 13 of upper inner core 1 and lower inner core 2 is subjected to polishing grinding processing；
Be conducive to form good interference fit between the upper end of lower inner core 2 and the lower ending opening of cavity 13, to avoid subsequent secondary
In injection moulding process, plastic cement enters inside cavity 13 through gap between the two.
3) upper end of lower inner core 2 interference fit is arranged in the lower ending opening of cavity 13, lower inner core 2 top with
It is hollow that sealing is formed between the inner wall of cavity 13, obtains grinding head main body 30；
4) grinding head main body 30 is put into mold and carries out quadric injection mould, form outer grinding in the outer surface of bistrique main body 30
Layer 3.
It should be noted that the outer grinding layer 3 is using Tritan TX2001, PMMA or PA production.Certainly, this is practical
Novel outer grinding layer 3 is not limited to above-mentioned making material, the free of contamination plastic material of other food-grades or alloy material.
