Abstract

The utility model relates to a combined grinding machine for gems, which belongs to a special apparatus for cutting and grinding small gems. The combined grinding machine for gems is additionally provided with a set of rough grinding mechanism on the basis of a Thailand produced grinding machine; a rough grinding disk is arranged on an operating table which is on the same horizontal level of a polishing disk; the rough grinding disk is supported by a control disk and is fixed on the rotary shaft of a rough grinding device; the rotary shaft is fixed on the supporting frame of the operating table through a bearing; a polishing device is directly driven by a motor; the motor is arranged on a foot frame; power is delivered to the rotating shaft of the rough grinding device by a belt through the polishing device. The utility model has the advantages of high efficiency, stable quality, low raw materials, auxiliary materials, and power consumption, and 40 percent of equipment investment and barrack occupation reduction.

Description

Combined grinding machine for gem

A kind of special equipment of cutting mill facet type jewel.

At present, facet type cutting machine kind is a lot of, as America and Europe, Hong Kong and Taiwan and homemade small-sized jewel cutting machine, its profile is different, but structural principle is roughly the same, promptly by the operating desk of a station with can drive the control panel group of mill rotation, and can clamping sticking bar and can determine that the facet head group of cutting at the jewel corner and the elevation angle constitutes, such cutting machine is furnished with respectively one of roughing mill and polishing disk.The roughing mill of being joined is more satisfactory, it is very fast to cut mill speed, the facet of wearing into is also more smooth smooth, and the polishing disk of being joined is not up to expectations, its polishing disk mostly is soft terne metal or fine copper, and not only polishing velocity is slow, and polishing disk is abrasion deformation very easily, the mill surface needs often finishing, and the polished diamond powder that expends is also more.In addition, also to load onto roughing mill earlier during use, cut grind a collection of jewel after, take off roughing mill again and change polishing disk and descend polishing process one, formality is loaded down with trivial details, the dismounting trouble is time-consuming.A kind of jewel cutting machine that Thailand produces, though have the dual-use function of fine grinding and polishing, this cutting machine also need dispose the blank that the manual pulley grinding machine grinds jewel, and use manual pulley grinding machine, not only the jewel angle is difficult for grasping, and the facet camber face of wearing into, and rough surface.In addition, when entering polishing process after the corase grind, also need to go up drilling rod again, check angle once more, the specification requirement height, operation easier is big, inefficiency.

The purpose of this utility model provides a kind of combined type jewel grinding machine, and it is simple that it cuts grinding process, high efficiency, and production cost is low, and durable in use.

The purpose of this utility model is achieved in that it is to produce on the basis of grinding machine in Thailand, increase by a cover corase grind mechanism, roughing mill is installed on the operating desk with the same horizontal plane of polishing disk, roughing mill is supported by control panel, and be fixed in the corase grind device rotating shaft, this rotating shaft then through bearing fixing on the operating desk support.Directly drive burnishing device polishing disk is rotated at a high speed by being positioned at motor on the foot rest, power passes to the rotating shaft of corase grind device through burnishing device rotating shaft and belt thereof by the belt pulley that is fixed in the rotating shaft of corase grind device more then, makes roughing mill rotary work simultaneously.

Be symmetrically distributed before and after the operating desk, uniform polishing disk in the left and right sides and roughing mill form the operating desk with two stations.

The utlity model has following advantage:

It not only integrates the advantage that Thailand produces grinding machine and homemade grinding machine, and its combined result makes the technical process of cutting the mill jewel simplify greatly, operation easier reduces greatly, corase grind and polishing two procedures can be interted on same operating desk and carry out, behind the sticking bar, after having ground a facet on the roughing mill, move on on the polishing disk on the former stone of facet type jewel this facet polishing, so just can only lastly glue bar, check whole processing that a time angle had both been finished jewel.Reduced formality of sticking bar up and down and the trouble that angle is checked in polishing, it is very convenient to manipulate, and operating efficiency doubles than home-made machine, improves 30～50% than Thailand machine.Reliable product quality, its yields reaches more than 98%.Production cost is low, and the use amount of its polishing powder only is 1/10th of a home-made machine, and the consumption of auxiliary material also significantly reduces, and the raising of yields has also just reduced the raw-material consumption of jewel simultaneously.In addition, operating desk has been arranged two stations, and the both sides, front and back all can be operated, and can go up two operative employees simultaneously and process and be independent of each other, and like this, no matter be equipment investment, or worker-house area occupied and power consumption all can reduce 40%.Secondly the utility model adopts wooden bearing, makes between axle and the bearing to keep no gap to contact, so there is not the mechanical movement noise basically.

Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.

Referring to Fig. 1,2, the utility model comprises operating desk 1, roughing mill 8, polishing disk 3, motor 2 and transmission device thereof, also is furnished with hand-held angle machine (figure slightly) in addition, it is characterized in that: operating desk 1 front and back are symmetrically distributed, left and right sides table top correspondence is provided with polishing disk 3 and roughing mill 8, motor 2 is installed on operating desk 1 foot rest, its driving belt 6 is sleeved on the burnishing device belt pulley 5 through motor pulley, and burnishing device belt pulley 5 and polishing disk 3 are separately fixed in the burnishing device rotating shaft 4, and rotating shaft 4 is fixed on operating desk 1 support by wooden bearing 7.Roughing mill 8 is by control panel 9 supportings, by clamp nut 14 location, and be fixed in the corase grind device rotating shaft 11, wooden bearing 15 of rotating shaft 11 usefulness and sliding bearing 10 be fixed on the corresponding position of burnishing device on, corase grind device driving belt 13 is sleeved in the burnishing device rotating shaft 4 through its belt pulley 12, belt pulley 12 is fixed in the corase grind device rotating shaft 11, and drives rotating shaft 11 rotations, makes roughing mill 8 rotary works.Roughing mill 8 is selected homemade diamond dust mill for use, the fine grinding polishing disk that polishing disk 3 selects for use Thailand to produce adopts the rigidity high-abrasive material to make, and is carved with intensive shallow slot at working surface, compacting fine grinding diamond dust in one section zone of outer circumference, compacting polishing powder in one section zone of inner circumference.During the jewel polishing, from the past interior propelling of the outer rim of mill, polishing velocity is very fast.
