Fig. 3 is the schematic diagram that the present invention is used to make the device of ball fixed block.
The specific embodiment
Describe the present invention with reference to the accompanying drawings.As depicted in figs. 1 and 2, ball fixed block provided by the invention comprises the fixed block 1 that is formed by plastic material and is embedded in spheroid 2 in this fixed block 1 securely.Spheroid 2 generally be diameter less relatively can be by the metal ball body of magnetic attraction, for example steel ball or nickel ball.For the ease of fixing and location, described fixed block is preferably square.
The process principle of ball fixed block is the material by heat fused fixed block 1 normally, makes the fixed block material of fusing coat spheroid 2 then, stops heating then and makes the fixed block cooling forming and spheroid 2 is firmly fixed at wherein.Therefore, the material of fixed block 1 is generally heating and can melts and cool off the plastic material that can be shaped.Preferably, to select fusing point for use be 100-200 degree centigrade plastic material to described plastic material.Simultaneously, the fixed block 1 that is embedded with spheroid 2 in inside in order to guarantee the machining accuracy of spheroid 2, requires fixed block 1 to have certain intensity and less degree of deformation after being fixed on the processing equipment.Therefore, described plastic material is preferably selected urea-formaldehyde moulding powder (being commonly called as urea-formaldehyde moulding powder) or novolac resin for use.Urea-formaldehyde moulding powder, with the Lauxite is the moudling powder of base stock, mainly flood filler (paper pulp) by the resin liquid of low polycondensation, drying, pulverizing back add colorant and the mixing of other auxiliary material and get, plastic products after being characterized in being shaped have bigger intensity, and translucent picture jade, so popular name urea-formaldehyde moulding powder.In the present invention, the spheroid that uses be preferably diameter less relatively can be by the metal ball body of magnetic attraction, because the less metal ball body of diameter utilizes the existing mechanical anchor clamps to be difficult to fixing and accurate location usually, is particularly advantageous so utilize ball fixed block of the present invention.Metal ball body can be in order to utilize manufacturing installation of the present invention to make easily by magnetic attraction, and this manufacturing installation will be described below.
Be embedded into spheroid 2 in the described fixed block 1 and can comprise a plurality ofly, these spheroids preferably have identical size, more preferably equally spaced be embedded in the fixed block 1 each other, and these spheroids 1 are preferably placed in the identical horizontal plane.As depicted in figs. 1 and 2, under fixed block 1 is square situation, the excircle point of described a plurality of spheroid 2 is positioned at a plane of square fixed block, perhaps also can be positioned at a parallel plane plane with square fixed block, the excircle point of promptly all spheroids can protrude in square fixed block a little and be positioned at same horizontal plane.In this case, can carry out for example grinding of machined to a plurality of spheroids 1 simultaneously, thereby improve working (machining) efficiency greatly.
In addition, a plurality of spheroids 2 equally spaced are embedded in the fixed block 1 each other, can easily the position of these spheroids be calculated and locate, thereby when a plurality of spheroids being carried out machined as perforation, can realize automation completely and precision machining, the efficient height.
Ball fixed block is being carried out in the machining process, can process together spheroid and fixed block, treat that spheroid machines after, can the mode by mechanical mode or heating be removed by the fixed block material around the spheroid.For the fixed block of thermoplastic, preferably remove spheroid fixed block material on every side by the mode of heating, can recycle the thermoplastic that melts by heating thus.
Below with reference to Fig. 3 the device that is used to make above-mentioned ball fixed block of the present invention is described in detail.
