Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, and more particularly to an automatic drilling machine for riveting a refrigerated truck chassis. Background Art

[0002] The refrigerated truck chassis is a key component of refrigerated trucks and riveted refrigerated container products. The chassis is divided into the top and bottom surfaces of the floor. In order to ensure that the subfloor, PE, etc. are securely fixed to the supporting beams in contact with the floor bottom surface, it is necessary to drill holes and then connect and fasten the wooden floor, subfloor, PE, etc. to the supporting beams with fastening screws.

[0003] Based on the above, the inventors found that most traditional drilling machines used for drilling holes in the chassis of refrigerated trucks and containers cannot automatically position and drill holes in the chassis wooden floor, sub-floor, PE, etc. and the supporting beams. Manual positioning and marking are required, and then a handheld drilling machine is used to perform the drilling operation. This not only requires an increase in the number of workers and increases costs, but is also relatively inconvenient to operate, reducing production efficiency. Therefore, in view of this, research and improvement are conducted on the existing structure to provide an automatic drilling machine for riveted refrigerated truck chassis, in order to achieve a more practical purpose.
