Abstract

The utility model discloses a quartzy fixture device who grinds machinery, it contains the anchor clamps body that comprises well core bar and both sides ptergoid bone, through tightening band wheel on the main shaft of well core bar, also tightening band wheel on the main shaft of a servo motor or corner cylinder, the mode of two belt pulleys is connected to the belt, realize that servo motor or corner cylinder drive the anchor clamps body and make a round trip to overturn, just so the be convenient for face that trades of quartzy pearl, realize automatic processing's effect, through fixed cylinder outside well core bar, and the push rod through being connected with the cylinder, the messenger fixes the removal of moving the both sides ptergoid bone at the sold inside the country subband of well core bar, the freedom adjustment of through -hole size is held in the realization, messenger fixture device is suitable for the quartzy pearl with all kinds of specifications, through sleeve spring on the pin, make the both sides ptergoid bone return the convenience that contracts, adopt the fixture device of above -mentioned structure, the automatic upset of anchor clamps has not only been realized, the problem of the inconvenient technique of current quartzy pearl turn -over is solved, and the freedom adjustment who holds the through -hole has been realized, make fixture device practicality more.

Description

The grip device of crystal grinder tool

Technical field

The utility model relates to a kind of fixture, specifically a kind of grip device of crystal grinder tool.

Background technology

Traditional crystal pearl grinding machinery, comprise frame, mill, push pin, pearl is arranged, fixture, busbar, when grinding crystal pearl, first crystal can be put into fixture, then pearl is made to arrange, fixture, busbar is corresponding, start busbar the crystal in fixture to be pushed in the chuck of pearl row, then pearl row is moved to mill place to grind, when having ground one side and having needed face of changing to grind: a kind of way starts pushing pin of pearl row top, crystal on pearl row folding head is pushed fixture, then crystal is taken out from fixture, change a face to put back again in fixture, start busbar the crystal in fixture to be pushed again in the chuck of pearl row, and then pearl row is moved to mill grinding, the visible process needing experience to place crystal for twice in this process in fixture, this process is loaded down with trivial details, and traditional fixture can not open, turn increase the difficulty of operation, and another kind of way is when grinding crystal pearl second, when crystal pearl is got back in fixture again, we have torn fixture open and have turned face and install back, so not only the labour intensity of inefficiency but also workman is also high.

Utility model content

In view of the familiar lacunas existing for existing grip device, technical problem to be solved in the utility model is, provide a kind of can the crystal grinder tool grip device of automatic turnover, and such grip device applicable processing with the crystal pearl of all size simultaneously.

For realizing above-mentioned technique effect, the grip device of crystal grinder tool described in the utility model, it comprises chuck body, described chuck body is made up of polylith clamp body, and having multiple receiving opening in the junction of two clamp bodies, described chuck body realizes upset by servomotor or swing clamp cylinder.

For realizing another technique effect of the utility model, described clamp body is three pieces, the concrete top of therebetween has a holding tank, the holding tank left and right sides connects the clamp body in outside by pin, the external side of intermediate holder is also provided with cylinder, drives push rod to promote two pins outer clamp body is moved to both sides by cylinder.

But said structure cannot realize the clamp body automatic retracted effect outside two, will inevitably affect working (machining) efficiency like this, therefore pin needs cover have elastic force apparatus.

As a kind of preferred version that servomotor or swing clamp cylinder drive chuck body to rotate, on described servomotor or its main shaft of swing clamp cylinder, cover has belt pulley, on the main shaft of chuck body, also cover has belt pulley, connects two belt pulleys realize chuck body upset by belt.

Due to the utilization of technique scheme, the utility model compared with prior art has the following advantages: the automatic turning 1, achieving fixture, and such design not only reduces labour intensity, and improves production efficiency; 2, achieve the adjustable effect of fixture, make it be suitable for the clamping with the crystal pearl of all size size.

Accompanying drawing explanation

Fig. 1 is the structural representation of the grip device of crystal grinder tool described in the utility model.

Fig. 2 is the structural representation that therebetween is concrete.

Fig. 3 is the another kind of structural representation that therebetween is concrete.

As described in Fig. 1 to Fig. 3,1, chuck body; 2, center bone; 3, flank bone; 4, receiving opening; 5, servomotor; 6, holding tank; 7, pin; 8, cylinder; 9, push rod; 10, spring; 11, belt pulley; 12, belt.

Detailed description of the invention

Below by specific embodiment, the utility model is further illustrated.

As depicted in figs. 1 and 2, the grip device of crystal grinder tool described in the utility model, it comprises chuck body 1, above-mentioned body is flexibly connected by three pieces of clamp bodies and forms, can be formed by guide shaft serial connection specifically, described three pieces of clamp bodies are respectively middle center bone 2 and the flank bone 3 of both sides, and have at the phase connection place that it connects between two a row with place the receiving opening 4 of crystal pearl, center bone 2 is connected with main shaft, and on main shaft, be connected with belt pulley 11, the upset of chuck body 1 is realized by connecting another belt pulley 11 and the belt 12 being connected two belt pulleys on the main shaft of a servomotor 5 or swing clamp cylinder, like this when in the receiving opening 4 getting back to clamp body after crystal ball one side has been ground, clamp body can automatic turning,

Further illustrate, center bone 2 upper surface has a holding tank 6, holding tank 6 left and right sides is connected with the flank bone 3 of both sides by a pin 7, drive push rod 9 to promote two pins 7 by the cylinder 8 outside center bone 2 and realize both sides ptergoid bone 3 outwards movement, so just achieve the adjustment of receiving opening 4 size, of course and preferably in center bone 2 both sides, pin 7 and cylinder 8 are all installed, for the ease of both sides ptergoid bone 3 automatic retracted, two pins 7 also need cover to have spring 10;

In said structure, center bone 2 and cylinder 8 are the level of state, with servomotor 5 in vertical state;

But above-mentioned center bone 2, cylinder 8 and servomotor 5 can also be another kind of stateful connection, as shown in Figure 3, center bone 2 is angularly constant with servomotor 5 institute, cylinder 8 is fixed on center bone 2 top, and the cylinder 8 of such fixed top also can promote pin 7 by two respectively, of courses such structure servomotor 5 and also can directly be connected with center bone 2 main shaft;

Above-mentioned grip device also needs to mix busbar in use and pearl is clapped, and not in the scope of the utility model protection, briefly explains at this due to both prior aries.

The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable modifications and changes to above-mentioned embodiment.Therefore; the utility model is not limited to detailed description of the invention disclosed and described above; also should fall in the protection domain of the utility model claim modifications and changes more of the present utility model; in addition; although employ some particular term or title in description; but these particular term or title are just for convenience of description, do not form any restriction to the utility model.
