Steel plate drilling device with shock-absorbing and returning functions

Abstract

The invention discloses a steel plate drilling device with functions of shock absorption and return, which comprises a second locking bolt, an anti-slip pad, a push rod, a handle, a return spring and a control switch, through which the second locking bolt is connected through the screw thread. The steel plate in the slot is rotated and squeezed in the hole, thereby realizing the fixation of the steel plate. The anti-skid pad is used to increase the friction between the second locking bolt and the steel plate, and the position of the slider on the first slide rail is adjusted. The purpose of drilling different positions of the steel plate is realized, and the practicability of the equipment is improved. After the drilling of the steel plate is completed, the handle is released, and the push rod returns to its position under the action of the return spring, which is convenient for the steel plate to be drilled again. Drilling saves time and labor and improves the drilling efficiency. At the same time, the return spring is used to absorb the vibration generated during the drilling process, so as to avoid the numbness of the operator's hand holding the handle due to excessive vibration, which further improves the user experience. Availability of equipment.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a steel plate drilling device with functions of shock absorption and return. Background technique [0002] The steel plate is a flat steel material that is poured with molten steel and pressed after cooling. Steel plates are flat, rectangular and can be rolled directly or cut from wide strips. Steel plates are classified according to thickness, thin steel plates < 4 mm (thinnest 0.2 mm), thick steel plates 4-60 mm, and extra-thick steel plates 60-115 mm. Steel plates are divided into hot rolling and cold rolling according to rolling. The width of the thin plate is 500~1500 mm; the width of the thick plate is 600~3000 mm. Sheets are classified by steel type, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron sheets, etc.; by professional use, the...

Problems solved by technology

[0003] In the process of steel plate processing, the steel plate drilling device is usually used to drill the steel plate. At the same time, the steel plate needs to be fixed before drilling the steel plate to avoid the movement of the steel plate during the drilling process. The existing steel plate drilling device cannot meet the requirements. For the purpose of fixing steel plates of different sizes, the vibration generated by the device due to drilling will cause numbness in the hand of the operator who has been in contact with the device for a long time. At the same time, the existing drilling device needs to be raised manually after the drilling is completed. Drill to continue drilling, time-consuming and laborious, greatly reducing the efficiency of drilling
