Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plate processing, more specifically, it relates to a plate drilling device. BACKGROUND

[0002] In the prior art, the plate drilling device as an important processing equipment is widely used in the production and manufacturing process of various plates, however, in the actual use process, the existing plate drilling device has many technical problems to be solved, which seriously affects the processing quality and production efficiency.

[0003] Firstly, the conventional plate drilling device generally adopts a single drill bit design, which has obvious deficiencies when multiple drilling of a single plate is required. The operator needs to frequently adjust the plate position or reposition the drill bit. This repetitive adjustment not only consumes a lot of time, but more importantly, this single drill bit structure cannot perform multi-point drilling simultaneously during batch production, which seriously restricts production efficiency and increases production cycle and labor cost.

[0004] Secondly, to solve the above problems, improved devices with multiple drill bit structures have appeared in the market. Although this design improves the processing efficiency to some extent, it still has significant defects in actual application, especially during the installation and disassembly of the drilling assembly. The operator often needs to use multiple professional tools and follow complex step sequences. This tedious adjustment process not only reduces work efficiency but also increases the labor intensity of the operator. More seriously, this design cannot flexibly adjust the spacing and number of drilling assemblies according to different product requirements, greatly limiting the applicability and practicality of the equipment and failing to meet the requirements of flexibility and efficiency in modern production.

[0005] In addition, to solve the problem of difficult adjustment of the drilling assembly, some manufacturers have adopted some quick disassembly structures in their equipment. However, these structures often pursue simplicity excessively, resulting in imperfect overall mechanism design and serious safety hazards. During continuous operation of the equipment, especially during high-speed operation or long-term use, the simplified mounting structure is prone to looseness, affecting drilling precision and quality. More seriously, the imperfect fixing mechanism may cause accidental shedding of the drilling assembly during operation, which not only causes equipment damage but also may endanger the personal safety of the operator. This structural stability problem seriously restricts the actual application effect of the equipment, making users need to frequently check and adjust during use, increasing maintenance burden and use cost.
