Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Fig. 1 to Fig. 7 show schematically show the grinding-polishing mill according to an embodiment of the present utility model.

In conjunction with shown in Fig. 1 to Fig. 3, grinding-polishing mill, grinding disc substrate 1 including ring-type, extension at grinding disc substrate 1 offers the fixing groove 21 of roll flute equably along the circumferencial direction of grinding disc substrate 1, the roll flute fixed area 2 of these roll flutes fixing groove 21 overall composition ring-type, the fixing groove 21 of roll flute is provided with roll flute 22, it is possible to adopt the mode of bonding to be bonded in by roll flute 22 on the outside inwall of the fixing groove 21 of roll flute.The internal ring wall of grinding disc substrate 1 is evenly equipped with installation locating slot 7, grinding disc substrate 1 can be positioned to the rotary output axis of grinding machine by installing locating slot 7, and threadably grinding disc substrate 1 is fastened on the rotary output axis of grinding machine by the connecting hole 8 being located at bottom grinding disc substrate 1.

As shown in Figure 1, one eccentric throw S of axis of rotation of the axis of rotation deviation grinding disc substrate 1 of roll flute 22, grinding disc substrate 1 does gyration by the drive of the rotary output axis of grinding machine, roll flute 22 in roll flute fixed area 2 is synchronized with the movement under the drive of grinding disc substrate 1, owing to the axis of rotation of roll flute 22 deviates the axis of rotation of grinding disc substrate 1, therefore roll flute 22 will do Uncertain Eccentricity motion, namely certain the certain movement locus on roll flute 22 is as shown in Figure 5, such movement locus of roll flute 22 will make the grinding of workpiece remove more uniform, improve grinding accuracy and the grinding efficiency of mill.In the present embodiment, eccentric throw S is 2.2mm-2.8mm, such eccentric distance, it is possible to reach preferably grinding, polishing effect.The eccentric throw S that varies in size according to grinding disc substrate can be 2.2mm, 2.5mm or 2.8mm.

Shown in Fig. 1, Fig. 5 and Fig. 6, the top of grinding disc substrate 1 forms the reservoir 3 of ring-type, the bottom of reservoir 3 annularly forms fistulae 4, the common cross section of reservoir 3 and fistulae 4 is funnel-form, and the coolant at grinding disc substrate 1 top can be led in the choked flow groove 5 of the ring-type of the bottom of grinding disc substrate 1 by reservoir 3 by fistulae 4.Coolant in reservoir 3 is by under the effect of the centrifugal force of grinding disc substrate 1 gyration, it will be guided in choked flow groove 5 along fistulae 4 so that grinding disc substrate 1 can uniformly cool down.

In the present embodiment, the cross section of choked flow groove 5 is inverted v-shaped, under the influence of centrifugal force, coolant in choked flow groove 5 can be uniformly dispersed on the mill roll flute grinding area with absorption surface along the inclined-plane of V-shaped, can effectively stoping coolant liquid to become under plume along the inwall of grinding disc substrate 1, further raising coolant is scattered uniformity in grinding area.Such that it is able to prevent coolant to be subject to the impact of eccentric motion, cause coolant skewness on grinding disc substrate 1, cause the burning of grinding disc substrate 1 local heating.

In conjunction with Fig. 1, shown in Fig. 3 and Fig. 4, the following current transition part 6 formed by an inclined-plane is also formed between choked flow groove 5 and reservoir 3, following current transition part 6 is between fistulae 4 and choked flow groove 5, one wall of the inclined-plane of following current transition part 6 and V-type choked flow groove 5 is crossed to form the tip 60 of a ring-type, the outlet at bottom of fistulae 4 leads to the upper edge of following current transition part 6, the coolant derived from fistulae 4 is by the effect of centrifugal force, first flow through following current transition part 6, coolant is evenly distributed on the inclined-plane of following current transition part 6, then it is thrown on the roll flute grinding area with absorption surface through the ring-type tip 60 on the lower edge of following current transition part 6.

Adopt the combination of choked flow groove 5 and following current transition part 6, such structure, the coolant distribution in grinding area can be effectively improved, it is suitable for grinding disc substrate 1 in high speed rotating grinding works, and coolant liquid is played homodisperse effect by ring-type tip 60, can ensure that coolant is annularly uniformly spilt on the grinding area of roll flute and absorption surface, further avoid coolant and become to cause under plume coolant dispersion on the roll flute roll flute grinding area with absorption surface uneven along the inwall of grinding disc substrate 1.

As depicted in figs. 3 and 5, in the present embodiment, on choked flow groove 5, following current transition part 6 and fistulae, the cross section of transverse plane 9 distribution is stepped, while ensureing mill structure function, effectively reduces the weight of mill itself.

Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the premise creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into protection domain of the present utility model.
