Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements related to the present invention are shown in the drawings.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the operation technology, in order to prevent the pallet from generating deformation exceeding the operation technology, thereby ensuring the completion of the operation technology and simultaneously prolonging the service life of the pallet, as shown in fig. 1-3, the utility model provides a pallet. This pallet that accompanies includes: the device comprises a supporting plate 1, a positioning pin 2 and a bearing pin 3; the supporting plate 1 is used for supporting a workpiece 4; the positioning pin 2 is vertically and fixedly arranged on the supporting plate 1, and the positioning pin 2 is matched with the supporting plate 1 to position the workpiece 4; the bearing pins 3 are vertically and fixedly arranged on the supporting plate 1, one end of each bearing pin 3 extends out relative to the lower end face of the supporting plate 1, and a plurality of bearing pins 3 are arranged on the supporting plate 1; the carrier pin 3 is configured to: when the supporting plate 1 conveys the workpiece 4, the upper end surface of a bearing plate of a mechanism for conveying the workpiece 4 is abutted with one end of the bearing pin 3, which extends out relative to the lower end surface of the supporting plate 1.
The positioning pin 2 is arranged on the supporting plate 1 to position and support a workpiece 4, the supporting plate 1 is provided with a plurality of bearing pins 3, one ends of the bearing pins 3 extend out relative to the lower end face of the supporting plate 1, when the supporting plate 1 conveys the workpiece 4, the upper end face of a bearing plate of a mechanism for conveying the workpiece 4 is abutted against one ends of the bearing pins 3 extending out relative to the lower end face of the supporting plate 1, so that the supporting plate 1 is supported by bearing the bearing pins 3, the pallet in the operation process is not directly subjected to the force applied by process equipment, and the force separation between the positioning transmission of the workpiece 4 and the operation of the process equipment is realized; the precision of the pallet can be maintained for a long time, so that the service life of the pallet can be prolonged.
