Handheld memory type hoe sinking device

Abstract

The invention relates to the technical field of structural design of air purification equipment, in particular to a handheld memory type hole sinking device. The handheld memory type hole sinking device comprises a shell. A hole sinking drill bit is arranged at the front end of the shell, a motor is arranged in the shell, the hole sinking drill bit is connected with the motor through a connectingrod, a speed reducing mechanism is arranged at the joint of the motor and the hole sinking drill bit, an MCU module, a power module and a relay are further arranged in the shell, the relay is connected with the MCU module, and the power module is connected with the MCU module and the relay. A handle is arranged on the lower portion of the middle of the shell, a trigger switch is arranged at the front end of the handle and connected with the MCU module, a timing button and a counting button are further arranged on the side portion of the shell and connected with the MCU module, the motor is connected with the relay, and an indicating LED lamp is further arranged outside the shell and connected with the MCU module. Compared with the prior art, the handheld memory type hole sinking device hashole depth and hole number memory functions, and is convenient to use, and machining is standard.

Description

【Technical Field】 [0001] The invention relates to the technical field of air purification equipment structure design, in particular to a hand-held memory type counterbore device. 【Background technique】 [0002] In the case of small batches of sheet metal processing, or when the processing space for parts is limited, manual handheld equipment processing is required. Pure manual operation will cause the processed apertures to vary in size and affect the product beauty. The traditional technical solution is to customize various Limit countersinking drill bits, or limit devices, these methods have great disadvantages: 1. The thickness of the sheet metal is small, and the special thickness control of the customized hole drilling bit with boss limit is complicated to achieve and the customization cycle is long. The cost is high, the versatility is poor, and the drill bit needs to be replaced frequently to realize the operation of the entire process; 2. The limit device is used to contr...

[0002] In the case of small-batch sheet metal processing, or when the processing space of parts is limited, manual hand-held equipment is required for processing. Pure manual operation will result in different sizes of processed holes and affect the aesthetics of the product. The traditional solution is to customize various Limit counterbore drills, or limit devices, these methods have great disadvantages: 1. The thickness of the sheet metal is small, and custom-made special thickness control hole-forming drills with boss limit are complicated to realize and the customization period is long. The cost is high, the versatility is poor, and the drill bit needs to be replaced frequently to realize the operation of the whole process; 2. The limit device is used to control the thickness, and the precision control of the limit device is high, and the limit height needs to be adjusted frequently to adapt to different The thickness of the counterbore requires good versatility, but it is affected by the positioning surface when used, and the scope of use is limited. The attached limit mechanism is usually complex in structure, large in size, and inconvenient to carry, which increases the burden on construction personnel during operation.
