Description

Rounding fixture and rounding device

The invention relates to a rounding jig and a rounding device, in particular to a rounding jig and a rounding device which can simultaneously round both sides of a workpiece.

In the field of optics, it is usually necessary to make optical elements such as lenses, filters, and the like of a camera into a circular shape. However, the workpieces that are initially cut during industrial processing are generally square, so the square workpiece needs to be rounded to have rounded edges to meet the needs of optical applications.

Cylindrical grinding machines are widely used to grind workpieces of various shapes into a circular shape (see High Efficiency Deep Grinding of a Low Alloy Steel with Plated CBN Wheels), CIRP Annals-Manufacturing Technology, pp. 241-244, Volume 51, Issue 1,2002). The cylindrical grinding machine grinds the workpiece fixed by the fixing device with a high-speed rotating grinding wheel to complete the rounding treatment of the workpiece.

As shown in FIG. 1 , the fixing device 200 has a receiving groove 12 . The accommodating groove 12 has a V-shaped cross section for accommodating the prismatic workpiece 14 to be rounded. The prismatic workpiece 14 can be formed by bonding a plurality of square sheet workpieces 16 via a glue such as ultraviolet glue. In operation, the prismatic workpiece 14 is usually fixed in the accommodating groove 12, and the prismatic workpiece 14 is ground by a grinding wheel. Since the circumferential surface of the grinding wheel is usually provided with a grinding groove, the grinding groove has a section The shape is semi-circular, and the size of the semicircle is ultimately required The semicircular shape of the circular product also coincides with each other. Therefore, the portion of the prismatic workpiece 14 exposed to the receiving groove 12 can be ground into a half cylinder, that is, one side of the prismatic workpiece 14 is rounded; A spheroidal prism workpiece 14 is taken out from the accommodating groove 12, and its semi-cylindrical portion is fixed in another device (not shown), and the other surface is ground by a grinding wheel to grind the prism workpiece 14 into a complete one. The cylinder, and finally the removed cylindrical body is removed and disassembled to obtain a number of desired round products.

However, this method can only roll a single side into a half circle at a time. After finishing one side rounding, the workpiece needs to be turned over, and the other side is polished by a grinding wheel, which is tedious and time consuming.

In view of this, it is necessary to provide a rounding jig and a spheronizing device which are simple in structure and high in efficiency.

A rounding fixture for fixing a workpiece to be rolled, comprising: a support frame, the support frame comprising a bottom plate, a first side plate and a second side plate respectively extending from opposite ends of the bottom plate, and respectively The first side plate and the second side plate extend from the two cover plates opposite to the bottom plate, the two cover plates are respectively provided with at least one second threaded hole; a first clamping member, the first end portion of which is connected to the second a side plate, the second end is a free end; a second clamping member, the first end portion of which is connected to the first side plate, the second end portion is disposed opposite to the free end of the first clamping member, and cooperates with each other to clamp Holding the workpiece; a loading platform for carrying the workpiece, the loading platform is movable in a direction of approaching or moving away from the workpiece; at least one elastic member is disposed between the bottom plate and the loading platform for supporting the loading platform; And at least two adjusting members are respectively disposed on the second threaded holes of the two cover plates and abut against the loading platform.

A spheronization device comprising two grinding wheels with semi-circular grooves and a rounding jig according to the above, the two grinding wheels are respectively disposed on two sides of the workpiece for the same workpiece Grinding is carried out.

Compared with the prior art, the rounding device clamps and fixes the workpiece by the first clamping member and the second clamping member, and then simultaneously rounds both sides of the workpiece by using two grinding wheels to obtain a finished product, which is simple in structure and efficient. high.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 2 to FIG. 4, an embodiment of the present invention provides a spheronization apparatus 100 for simultaneously performing rounding processing on a plurality of workpieces 30 to be rolled. In this embodiment, the workpiece 30 to be circulated is square. The spheronization device 100 includes a support frame 10, a first clamping member 20, a second clamping member 40, a loading platform 50, four elastic members 60, two adjusting members 70, and two grinding wheels 80.

The support frame 10 includes a bottom plate 102, a first side plate 104 and a second side plate 106 extending from opposite ends of the bottom plate 102, and a bottom plate 102 extending from the first side plate 104 and the second side plate 106. Opposite the two cover plates 105. The bottom plate 102 has four holes 1022. The first side plate 104 is provided with a first threaded hole 1042, and each of the cover plates 105 is respectively provided with two second threaded holes 1052.
