Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of line board cutting processing, and particularly relates to a line board cutting processing equipment without pin positioning. BACKGROUND

[0002] Line board manufacturers process the shape of finished products and semi-finished products according to process requirements or customer requirements. Traditional forming methods include machine cutting, plate cutting, hand cutting, and the like. Numerical control cutting machines are widely used in the process of producing line boards due to their safety, high efficiency, and high forming precision. In the production process, in order to improve efficiency and save costs, each small-area line board is manufactured on a large-area plate, and then the small-area line boards are cut from the plate by a numerical control cutting machine. In the traditional numerical control cutting machine, multiple positioning pins are arranged on the workbench to avoid affecting the precision of line board cutting during the cutting process due to displacement of the line board. Corresponding pin holes are arranged on each line board for the positioning pins to insert into. The line board is fixed on the workbench through the cooperation of the pin holes on the line board and the positioning pins on the workbench, so as to facilitate the cutting work of the line board.

[0003] However, when different models of line boards need to be cut, the multiple positioning pins on the workbench for the previous model of line board need to be removed, and then the positioning pins matched with the pin holes on the line board to be cut are reinstalled on the workbench. The operation is relatively cumbersome and inconvenient. In addition, since the sizes of different models of line boards are different, the sizes of the pin holes are also different, which leads to the need to install different models of positioning pins.

[0004] Therefore, it is necessary to design a processing device without the need to install positioning pins. UTILITY MODEL CONTENTS
