Description

Workpiece pressing mechanism of cutting equipment

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of automatic cutout machine, especially, relate to a cutting equipment's work piece hold-down mechanism.

[ background of the invention ]

At present, after metal cutting equipment of most production enterprises cuts metal workpieces, scratches are left on the cut surfaces of the cut workpieces, so that the attractiveness is affected; in addition, the automatic cutting equipment in the prior art cannot position and feed the tailing part, so that the tailing is left for a long time and is very wasted; in the prior art, patent No. 201820540756.9 discloses a metal workpiece cutting device, which can only ensure the verticality of the cutting surface, but cannot ensure the accuracy of the cutting track under the overlooking angle, and is prone to the phenomenon of cutting track deflection, so that the cutting precision is rejected due to unsatisfactory cutting precision, although the end parts of two sides of the workpiece cutting position are compressed.

Therefore, there is a need to provide a new workpiece pressing mechanism of a cutting apparatus to solve the above problems.

[ Utility model ] content

The utility model discloses a main aim at provides a cutting equipment's work piece hold-down mechanism, has improved the position precision of cutting work piece greatly, has ensured the precision of cutting.

The utility model discloses a following technical scheme realizes above-mentioned purpose: a workpiece hold-down mechanism of a cutting device comprises a fixed hold-down mechanism and a movable hold-down mechanism which hold down the end parts of two sides of the cutting part of a workpiece to be cut, the movable pressing mechanism bears a cut workpiece and can move along the feeding direction, the fixed pressing mechanism comprises a first bottom plate for supporting one end of the cutting position of the workpiece, a first pressing plate positioned above the first bottom plate, a first air cylinder for driving the first pressing plate to move up and down, and a lateral positioning mechanism positioned at the upstream of the first pressing plate and matched with the first pressing plate to fix the end part of one side of the cutting position of the workpiece, the third positioning lateral mechanism comprises a second air cylinder, a connecting plate driven by the second air cylinder to move up and down, a third air cylinder fixed on the connecting plate in an adjustable position, and a lateral push plate driven by the third air cylinder to laterally compress a workpiece.

Furthermore, the movable pressing mechanism comprises a second bottom plate for supporting the part of the workpiece to be cut off, a second pressing plate positioned above one end, close to the cutting position, of the second bottom plate, and a fourth cylinder for driving the second pressing plate to move up and down.

Further, a cutting gap is formed between the second bottom plate and the first bottom plate.

Compared with the prior art, the utility model relates to a cutting equipment's work piece hold-down mechanism's beneficial effect lies in: the position precision of the cutting workpiece is greatly improved, and the cutting precision is guaranteed.

[ description of the drawings ]

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

the figures in the drawings represent:

100 workpiece pressing mechanism of cutting equipment;

1, a fixed pressing mechanism, 11 a first bottom plate, 12 a first pressing plate, 13 a first air cylinder, 14 a lateral positioning mechanism, 141 a second air cylinder, 142 a connecting plate, 143 a third air cylinder and 144 a lateral pushing plate;

2, a movable pressing mechanism, 21 a second bottom plate, 22 a second pressing plate and 23 a fourth cylinder;

and 3, cutting a gap.

[ detailed description ] embodiments

Example (b):

referring to fig. 1, the workpiece pressing mechanism 100 of the cutting apparatus in this embodiment includes a fixed pressing mechanism 1 and a movable pressing mechanism 2 for pressing two side ends of a cutting portion of a workpiece to be cut, the movable pressing mechanism 2 carries the cut workpiece and can move along a feeding direction, the fixed pressing mechanism 1 includes a first bottom plate 11 for supporting one end of a cutting position of the workpiece, a first pressing plate 12 located above the first bottom plate 11, a first cylinder 13 for driving the first pressing plate 12 to move up and down, a lateral positioning mechanism 14 located upstream of the first pressing plate 12 and cooperating with the first pressing plate 12 to fix one side end of the cutting position of the workpiece, the third positioning lateral mechanism 14 includes a second cylinder 141, a connecting plate 142 driven by the second cylinder 141 to move up and down, and a third cylinder 143 fixed on the connecting plate 142 with an adjustable position, And a lateral push plate 144 which is driven by the third cylinder 143 to laterally press the workpiece.

The movable pressing mechanism 2 comprises a second bottom plate 21 for supporting the part of the workpiece to be cut off, a second pressing plate 22 positioned above one end of the second bottom plate 21 close to the cutting position, and a fourth air cylinder 23 for driving the second pressing plate 22 to move up and down.

A cutting slit 3 is formed between the second base plate 21 and the first base plate 11.
