Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plate processing, and particularly relates to a workpiece automatic centering and positioning platform of a cold press. BACKGROUND

[0002] The cold press is an important mechanical equipment in the plate processing industry and is mainly used for extruding multiple layers of plates to make the plates tightly combined so as to meet the requirements of plate performance in different use scenarios.

[0003] During the working of the cold press, pressure is generated by means of a hydraulic system or a mechanical transmission device, multiple layers of plates are placed between upper and lower pressing plates of the cold press, and under the action of the pressure, adhesives and bonding materials between the plates are fully contacted and solidified, so that the connection and forming of the plates are realized.

[0004] During the production and processing, multiple groups of plates can be simultaneously pressed in the stroke range of the pressing plates of the cold press, and with the popularization of automation, multiple groups of plates can be sequentially conveyed to the cold press by means of a self-feeding feeding mechanism, so as to reduce the labor input and improve the production efficiency.

[0005] However, there is a prominent problem in the current automatic feeding process. After the plates are automatically fed, the plates cannot be automatically aligned. Due to various factors such as uneven friction of the conveying belt, weight difference of the plates and slight vibration of the feeding device, the plates are often in a staggered state when they reach the position of the pressing plates of the cold press. If manual arrangement is not performed, the plates that are not aligned will be unevenly stressed when the cold press exerts pressure, which not only affects the full and uniform contact of the adhesives and bonding materials between the plates, thereby affecting the solidification effect, but also can cause quality problems such as inconsistent thickness and uneven edges of the plates after forming. These quality defects will reduce the overall performance of the plates, so that the plates cannot meet the market demand for high-quality plates, and in severe cases, the products will be scrapped. Therefore, the above problems need to be solved. SUMMARY

[0006] In view of the above defects or deficiencies in the prior art, it is expected to provide a workpiece automatic centering and positioning platform of a cold press.

The base 320 is provided with a telescopic support plate 330 on the side close to the plate, for abutting and positioning the plate along the first direction.

[0052] In this embodiment, the base 100 is made of high-strength steel and extends along the first direction. Its length is determined according to the maximum length of the plate to be processed in actual production. A support platform is provided in the middle of the base 100.

The area of ​​the pressure plate 210 is adapted to the support platform and can completely cover the plate placed on the support platform.

[0054] In this embodiment, the slides 300 are respectively installed at both ends of the base 100 along the first direction. By synchronously driving the two slides 300 to move closer to each other, the support plate 330 can be used to abut against the plate to achieve centering and positioning of the plate along the first direction. Then, by driving the clamping arm 310 along the second direction, the plate can be effectively centered and positioned along the second direction.

[0055] In a preferred embodiment, the base 100 is provided with a corresponding linear bearing and a drive cylinder corresponding to the slide table 300; the slide table 300 is located between the two support columns 110 arranged along the second direction and is connected to the linear bearing through a first slide rail; the drive cylinder is located on the side of the slide table 300 away from the plate, the cylinder body is mounted on the base 100 and is connected to the slide table 300 through a piston rod.

[0056] In this embodiment, by installing the slide table 300 between the two support columns 110 and cooperating with the installation structure in which the slide table 300 is connected to the linear bearing via the first slide rail, the slide table 300 can slide to the side of the support column 110 close to the plate to position the plate, and can also be hidden to the side of the support column 110 away from the plate, thereby avoiding affecting the feeding.

[0059] In a preferred embodiment, the clamping arm 310 is connected to the base 320 via a second slide rail; the second slide rail is fixedly mounted on the clamping arm 310 and extends in a direction parallel to the extension direction of the clamping arm 310; a matching slider is provided on the base 320 corresponding to the second slide rail; the slider is fixedly mounted on the base 320 and is used to limit the sliding direction of the clamping arm 310.

[0060] In this embodiment, the clamping arm 310 is connected to the base 320 by a matching slider and a second slide rail. The second slide rail is fixedly installed on the clamping arm 310, while the slider is fixedly installed on the base 320. This allows one end of the clamping arm 310 to extend to the outside of the base 320 without the slider disengaging from the second slide rail.

[0061] In a preferred embodiment, a flap 350 is hinged to one end of the clamping arm 310 away from the drive gear 340; the flap 350 is connected to the clamping arm 310 via a tilting cylinder 351, which drives the flap 350 to rotate relative to the clamping arm 310.

[0062] In this embodiment, there are two flaps 350, which are respectively hinged and installed at the ends of the two clamping arms 310 in the same group that are far apart from each other. So that by flipping the flaps 350, the extension and retraction of the clamping arms 310 will not be affected, and the flaps can abut against the ends of the plate after flipping.

One end of the threaded sleeve 332 is fixedly connected to the support plate 330 by welding, and the other end is threadedly connected to the lead screw 331. When it is necessary to position the plate in the first direction, the lead screw 331 is driven to rotate by a motor. The rotation of the lead screw 331 causes the threaded sleeve 332 to move along the axial direction of the lead screw 331, thereby realizing the extension and retraction of the support plate 330. During the driving process of the lead screw 331, the rotation angle of the lead screw 331 is accurately measured by an encoder, thereby realizing precise control of the extension or retraction length of the support plate 330.
