Problems solved by technology

[0002] Drilling is a commonly used technical means in mechanical processing. When drilling a workpiece, the workpiece needs to be clamped and fixed first. Since the position of the clamping device is fixed, if the workpiece is flawed and the clamping device fixes the workpiece, the workpiece needs to be fixed. The location of the drill hole does not correspond to the drill bit, which will increase the machining error of the workpiece, resulting in unqualified products and unnecessary waste

Embodiment Construction

[0018] Further detailed explanation through specific implementation mode below:

[0019] The reference signs in the drawings of the description include: bracket 1, drilling motor 2, sun gear 3, planetary gear 4, ring gear 5, drill rod 6, output shaft 7, smooth part 8, blade 9, planet carrier 10, L Type rod 11, outer tube 12, slide rail 13, positioning frame 14, cylinder 15, hose 16, chip discharge hole 17, jaw 18.

[0020] Such as Figure 1 to Figure 5 As shown, a finely adjustable drilling device includes a bracket 1, a drilling mechanism and a clamping mechanism. The drilling mechanism comprises the drilling motor 2 at the right end of the mounting bracket 1, and the output shaft 7 of the drilling motor 2 is equipped with 4 series of planetary gears. The planetary gear 4 series includes a sun gear 3 coaxially installed on the free end of the output shaft 7. The sun gear 3 is meshed with three planetary gears 4 evenly distributed in the circumferential direction. The left e...

Abstract

The invention discloses a fine-tuning drilling device, and relates to the field of machine tool drilling. The fine-tuning drilling device comprises a support, a drilling mechanism and a clamping mechanism; the drilling mechanism comprises a planetary gear train, a drilling motor for driving the planetary gear train to rotate and fan blades, wherein the drilling motor is fixed on the support, and an output shaft of the drilling motor is coaxially fixed to a sun gear; drill rods and drill bits which are used for drilling are installed on planetary gears; a gear ring is divided into an engaging part and a smooth part, wherein the end part of the smooth part is closed, and the fan blades are installed on the inner side of the smooth part; a planet carrier wraps teeth of the sun gear and the planetary gears, and ventilation holes are formed in the planet carrier; an outer cylinder is connected to the outer side of the gear ring in a sliding mode, air inlet holes are formed in the outer cylinder, and the outer cylinder is in sliding connection with the planet carrier; a fastener for limiting rotation of the outer cylinder is installed on the support; the clamping mechanism comprises sliding rails, a positioning frame and an air cylinder, wherein a clamping part for clamping a workpiece is installed on the positioning frame, and the clamping part comprises a clamping jaw and an air bag for pushing the clamping jaw to slide; and the air bag communicates with the inside of the gear ring through a pipeline. According to the scheme, the drill bits can be finely tuned before drilling.

Description

technical field [0001] The invention relates to the field of machine tool drilling, in particular to a finely adjustable drilling device. Background technique [0002] Drilling is a commonly used technical means in mechanical processing. When drilling a workpiece, the workpiece needs to be clamped and fixed first. Since the position of the clamping device is fixed, if the workpiece is flawed and the clamping device fixes the workpiece, the workpiece needs to be fixed. The location of the drill hole does not correspond to the drill bit, which will increase the machining error of the workpiece, resulting in substandard products and unnecessary waste. In addition, when the workpiece is processed, it is necessary to collect chips to prevent the debris from splashing and affecting the surrounding working environment. Contents of the invention [0003] The invention intends to provide a finely adjustable drilling device to improve machining accuracy during drilling. [0004] I...
