Abstract
The utility model provides a metal bonded diamond dual-head sharpener, which comprises a flat-shaped base (1); three mounting holes (3) are formed on the base (1); and two diamond abrasion blocks are fixedly connected on the front side of the base (1). By adopting the reasonable dual-head structure, the dual-head sharpener enlarges the drainage space of abrasive dust, improves the dust drainage performance and heat radiation performance of an abrasive tip, improves the polishing efficiency, and also can effectively prevent the sharpener from departing from the abrasive tip during polishing.
Description
(1), technical field
The utility model relates to a kind of diamond abrasive tool, specifically a kind of metal-bonded diamond double end grinding tool.Be mainly used in for the stone material grinding apparatus supporting.
(2), background technology
Cement, concrete or stone floor generally adopt diamond disk to polish by the mode of " dry grinding " or " water mill " as the grinding apparatus of bistrique or renovate.Traditional grinding apparatus, grinding tool is connected with the equipment bistrique by nylon buckles, and this connected mode is easy to cause the disengaging of grinding tool and bistrique in the process of polishing fast.
In addition, the patent No. is that 200420098749.6 Chinese patent discloses " including the grinding tool by the synthetic ultra-fine granularity diamond segment of metallic bond ", and its primary structure feature is as follows: be provided with in the grinding part by the synthetic ultra-fine granularity diamond segment of metallic bond.The grinding part is uniformly distributed along the circumference on the matrix end face, and the diamond segment of two grinding parts is radially staggered.Because diamond segment is arranged in the grinding part, and is less with stone surface or contact area of ground, the polishing weak effect, grinding efficiency is low; And the form that adopts a plurality of grinding parts on the matrix end face, to be uniformly distributed along the circumference, this structure can cause the bistrique dust discharge poor, and heat transfer property is bad, and then causes grinding efficiency low.
(3), utility model content
The utility model purpose is, a kind of metal-bonded diamond double end grinding tool is provided, and first technical problem to be solved is: by rational bipitch structure, increase the drainage space of abrasive dust, improve the dust discharge performance and the thermal diffusivity of bistrique, and improve grinding efficiency.Another technical problem to be solved is: by grinding tool is fixedlyed connected with the bistrique locating hole of grinding apparatus, avoid grinding tool in when polishing and bistrique disengaging, influence operate as normal.To overcome the defective of existing grinding tool.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of metal-bonded diamond double end grinding tool comprises flat base, it is characterized in that: offer three installing holes on the base; Base front surface is fixedly connected with two diamond grinding blocks.
A kind of structure of diamond grinding block is: diamond grinding block is cylindric.
The axis of one of them cylindric diamond grinding block is positioned at the triangle scope that three installing hole central points surround; The axis of another cylindric diamond grinding block is positioned at outside the triangle scope that three installing hole central points surround.
The another kind of structure of diamond grinding block is: diamond grinding block is rectangular-shaped.
Wherein the first cuboid diamond grinding block is vertical on one side arbitrarily with the triangle that the formed rectangular long limit of the contact-making surface between the base and three installing hole central points surround, and this cuboid diamond grinding block one end is positioned within the triangle scope that three mounting center points surround, and the other end is positioned at outside the triangle scope; The second cuboid diamond grinding block is positioned at outside the triangle scope that three installing hole central points surround, and the side of formed rectangular long limit of the contact-making surface between the second cuboid diamond grinding block and the base and base is 70 °～110 ° angles.
Preferred version is: the side of formed rectangular long limit of the contact-making surface between the second cuboid diamond grinding block and the base and base is 85 °～95 ° angles.
Good effect of the present utility model is:
(1), grinding tool adopts bipitch structure, not only increase grinding tool and stone surface or contact area of ground, and the gap between abrading block is bigger, helps dispelling the heat and the discharge of grinding scrap the raising grinding efficiency.
(2), three installing holes cooperate with locating hole on the bistrique, grinding tool more stably can be fixed on the grinding machine, have avoided grinding tool in the grinding process to break away from the problem of grinding machine bistrique.
(3), when adopting the form of cylindric abrading block, abrading block contact with the stone surface camber line, the dark cut of difficult formation is applicable to the fine grinding of stone material.
(4), when adopting the form of cuboid diamond grinding block, two cuboid diamond grinding blocks are used, at first the small end face of the second cuboid diamond grinding block contacts polishing with stone surface or ground, owing to contact-making surface is little, so sharper; The large end face of the first cuboid diamond grinding block contacts polishing with stone surface or ground subsequently, because the contact face width, so the polishing wide ranges.Under the cooperation polishing of two cuboid diamond grinding blocks, can improve grinding efficiency effectively like this.
(4), description of drawings
Fig. 1 is the structural representation of embodiment one.
Fig. 2 is the structural representation of embodiment two.
(5), the specific embodiment
Below in conjunction with accompanying drawing and embodiment is provided, the utility model is further described.
Embodiment one
As shown in Figure 1, offer three threaded installing holes 3 on the tabular base 1, be used for fixedlying connected with the grinding machine bistrique by screw.Base front surface is fixedly connected with two cylindric diamond grinding blocks 2.The axis of one of them cylindric diamond grinding block 2 is positioned at three the triangle scope that 3 central point of hole surround is installed.The axis of another cylindric diamond grinding block 2 is positioned at outside the triangle scope that three installing hole 3 central points surround.
Embodiment two
As shown in Figure 2, offer three threaded installing holes 3 on the tabular base 1, be used for fixedlying connected with the grinding machine bistrique by screw.Base 1 front is fixedly connected with two cuboid diamond grinding blocks.Wherein the first cuboid diamond grinding block 4 is vertical with leg-of-mutton one side that three installing hole 3 central points surround with the formed rectangular long limit of base 1 contact-making surface, and these first cuboid diamond grinding block, 4 one ends are positioned within the triangle scope that three installing hole 3 central points surround, and the other end is positioned at outside the triangle scope.The second cuboid diamond grinding block 5 is positioned at outside the triangle scope that three installing hole 3 central points surround, and the second cuboid diamond grinding block is vertical substantially with the side of base with the formed rectangular long limit of the contact-making surface between the base.
