Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a sand cutting and engraving device for an engine cylinder cover. Background Art

[0002] At present, automobile engine manufacturers need to remove excess sand molds and engrave QR codes on cylinder head workpieces during the subsequent processing of cylinder head casting. In the current production process, after the robot takes the part from the casting machine, it clamps the cylinder head and moves to the fixed sand cutter. Through multiple movements and changes of postures, the sand molds around the cylinder head are removed, and then it moves to the laser engraving machine and places the workpiece on the engraving table. After the cylinder head workpiece is engraved, the robot grabs the workpiece and moves it to the subsequent process.

[0003] At present, this process has the following problems: the robot grabs the cylinder head to cut out the sand mold, and the sand molds of various parts of the cylinder head need to be removed separately, which requires more actions and takes up more beats; secondly, in the process of removing the sand mold, because the sand mold is removed by scratching, the cylinder head and the gripper will be displaced in this process, resulting in changes in the state of the cylinder head and causing inaccurate subsequent positioning.

[0004] At the same time, due to the rise of the concept of Industry 4.0, the requirements for automation of production lines in the automotive industry are getting higher and higher. It is necessary to develop a system to optimize and improve the above process flow and improve production efficiency and automation level. Summary of the invention

[0010] Furthermore, the sand cutting tool is installed on the sand cutting tool plate through a connecting rod.

[0011] Furthermore, in order to be able to perform sand cutting and sand removal in an all-round manner, the sand cutting knife has various specifications.

[0012] Furthermore, in order to ensure that the sand cutting mechanism does not deviate during operation, a positioning plate is provided on the upper part of the main frame; the first cylinder connecting seat, the second cylinder connecting seat, the third cylinder connecting seat, the first guide rod connecting seat, and the second guide rod connecting seat are fixed on the positioning plate, and the positioning plate is provided with a guide rod seat sleeve corresponding to the guide rod and the guide rod of the workpiece pressure rod mechanism.

[0013] Furthermore, a slide is provided on the main frame, and a workpiece positioning mechanism is provided on the slide.

[0014] The beneficial effect of the utility model is that an engine cylinder head sand cutting and engraving device is mainly composed of a main frame, a slide, a sand cutting mechanism, a laser engraving machine and other components. First, the cast cylinder head blank is placed on the slide (pick-up and placement station) by a robot, and then the slide moves to the sand cutting and engraving station. Next, the laser engraving machine engraves a QR code on the cylinder head. After the engraving is completed, the sand cutting mechanism works to cut sand on the cylinder head blank, and the cylinder head sand cutting and QR code engraving stations are gathered in one place, which reduces the handling action of the robot and reduces the damage to the cylinder head; a special sand cutting knife is used to remove the sand mold of the cylinder head blank, and only one action is needed to complete the removal of all the sand blanks, which is very efficient; the sand cutting station is changed to be carried out at a fixed position, which avoids the displacement of the cylinder head and the robot during the sand cutting process, thereby causing subsequent positioning problems.
