Abstract
An improved combined type diamond grinding disk comprises a grinding disk body, a plurality of grinding heads distributed on the front surface of the grinding disk body, and sunk screws. Threaded holes matched with the sunk screws are formed in the back surfaces of the grinding heads. The grinding disk body is provided with stepped holes used for assembly of the sunk screws, and the sunk screws penetrate through the stepped holes and are combined in the threaded holes in a screwing mode. The improved combined type diamond grinding disk is simple in structure and convenient to process. The threaded holes are formed in the back surfaces of the grinding heads and combined with the sunk screws in the screwing mode, and therefore the grinding heads can be connected to the grinding disk body firmly. In addition, the screw heads of the sunk screws are sunk into the stepped holes, and therefore the back surface of the grinding disk body can keep smooth, and the grinding disk body does not block tools on a machine table when being installed on the machine table.
Description
Technical field

For the ease of production in batch, at present more is first mill body and bistrique to be separated, and processes respectively, then assembles and make combined polishing disc.The assembling mode of existing combined polishing disc is that the back side by bistrique is fixedly connected with upper screw rod, and mill body is provided with the pilot hole suitable with this screw rod, bistrique by the screw rod on it through this pilot hole and screw with a nut at the back side of mill body.Although the dismounting of the assembling mode of combinations thereof formula mill is simple, easy operating, but the back side nut of being located at mill body protrudes the frock that can keep off board, thereby make troubles to the installation of mill, and the technique of standing screw comparatively bothers, in sintering, bistrique easily comes off on bistrique, nut protrude to be arranged also can mill moulded attractive in appearance in addition.
Utility model content
The utility model provides a kind of improved combined type diamond disk, its main purpose is to overcome installation inconvenience that existing combined polishing disc assembling mode exists, on bistrique the technique of standing screw comparatively bother and in sintering bistrique hold caducous defect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of improved combined type diamond disk, comprise mill body, a plurality of bistrique and sunk screw that is laid in this mill body front, the back side of described bistrique offers and the suitable screwed hole of this sunk screw, on described mill body, offer the shoulder hole for described sunk screw assembling, described sunk screw is through this shoulder hole and be combined on described screwed hole.
Further, described shoulder hole comprises the counter sink portion at the described mill body back side and the pilot hole portion that bore is less than this counter sink portion of being opened in, and the joint of described counter sink portion and pilot hole portion is an annular table inconsistent with the head of screw of described sunk screw.
Further, each bistrique all offers two screwed holes, and described shoulder hole and this screwed hole align and be located on described mill body.
Further, described bistrique comprises diamond grinding layer and the auxiliary layer being fastenedly connected with this diamond grinding layer, and described screwed hole is opened in this auxiliary layer.
Further, be laid with and be spacedly distributed at four bistriques of inner ring and be spacedly distributed at eight bistriques of outer ring on described mill body, wherein the bistrique on different circles is staggeredly arranged.
Further, the thickness of described diamond grinding layer is 9.5～10.5 mm, and the thickness of described auxiliary layer is 8.5～9.5mm.
Further, described auxiliary layer is provided with for loading the circular groove of sintered material powder at the middle part with diamond grinding layer joint face.
Compared to the prior art, the beneficial effect that the utility model produces is:
1, the utility model is simple in structure, easy to process, by the back side at described bistrique, offer screwed hole, again by screwing with a sunk screw, not only make bistrique connect on mill body more firm, and the head of screw of described sunk screw sinks in described shoulder hole, can, so that the mill body back side keeps smooth, while loading onto board, can not keep off the frock on board.
2, in the utility model, on described mill body, at inner ring, lay four bistriques and in outer ring, lay eight bistriques respectively, bistrique on Internal and external cycle is staggeredly arranged, bistrique is distributed comparatively even, can significantly promote the smoothness of mill cutting, grinding is even and satisfactory for result, can reduce the noise producing in grinding process.
Accompanying drawing explanation
Fig. 1 is used novel structural representation for this.
Fig. 2 is that Fig. 1 is along the cutaway view on A-A direction indication.
Fig. 3 is the enlarged diagram at B place in Fig. 2.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
With reference to Fig. 1.A kind of improved combined type diamond disk, comprise mill body 1, be laid in the bistrique 2 in this mill body 1 front, on described mill body 1, be laid with and be spacedly distributed at four bistriques 2 of inner ring and be spacedly distributed at eight bistriques 2 of outer ring, wherein the bistrique 2 on different circles is staggeredly arranged, like this can be so that bistrique 2 distributes comparatively even, the smoothness that can significantly promote mill cutting, makes grinding even and satisfactory for result, can reduce the noise producing in grinding process.
With reference to Fig. 1, Fig. 2 and Fig. 3.Each bistrique 2 is all fixed on mill body 1 by a sunk screw 3, the back side of each bistrique 2 is all offered two and is upper and lower spaced apart screwed hole 20, this screwed hole 20 arranges with described sunk screw 3 suitablely, on described mill body 1, offer the shoulder hole 10 for described sunk screw 3 assemblings, this shoulder hole 10 aligns and is located on described mill body 1 with this screwed hole 20.Described shoulder hole 10 comprises the counter sink portion 11 at described mill body 1 back side and the pilot hole portion 12 that bore is less than this counter sink portion 11 of being opened in, and the joint of described counter sink portion 11 and pilot hole portion 12 is an annular table 13 inconsistent with the head of screw 30 of described sunk screw 3.Described sunk screw 3 is through this shoulder hole 10 and be combined on described screwed hole 20.By offering screwed hole 20 at the back side of described bistrique 2, again by screwing with a sunk screw 3, not only make bistrique 2 connect on mill body 1 more firm, and the head of screw 30 of described sunk screw 3 sinks in described shoulder hole 10, can, so that mill body 1 back side keeps smooth, while loading onto board, can not keep off the frock on board.
