Problems solved by technology

However, if the supporting member is replaced frequently, the drilling must be interrupted every time the replacement is performed, thereby reducing the manufacturing efficiency.
Therefore, in the conventional drilling device, there is a problem in preventing the generation of burrs while suppressing the decrease in manufacturing efficiency.

Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0032] figure 1 It is a perspective view of the hole drilling apparatus of this embodiment. In addition, the drilling apparatus is used in a state of being placed on a horizontal installation surface. In addition, in the figure, the direction in which the arrow UP points corresponds to the vertical upper direction.

[0033] like figure 1 As shown in the figure, the drilling device 1 is equipped with a drill D (refer to figure 2 ) of the main shaft portion 12 (corresponding to the "drill holding portion" in the claims) moves along the axial direction (up-down direction) of the drill D to make holes in the workpiece W such as a printed circuit board. The hole drilling device 1 has a case 2 and a cover 3 covering the upper surface of the case 2 .

[0034] The casing 2 is formed in a rectangular parallelepiped shape. On the upper surface of the casing 2 are disposed the follo...

Abstract

The present invention provides a hole-drilling device that is excellent in manufacturing efficiency and capable of suppressing generation of burrs. The drilling device (1) has: a drill bit (D), which drills a hole on a workpiece (W); a main shaft part (12), which holds the drill bit (D) in a rotatable manner; a drill sleeve (40), which is connected to the main shaft part (12) Arranged oppositely, and press the workpiece (W) toward the main shaft part (12) side when the workpiece (W) is drilled; and a strip-shaped sheet (S), which is pressed when the workpiece (W) is drilled Clamped between the bushing (40) and the workpiece (W).

Description

technical field [0001] The present invention relates to a hole opening device. Background technique [0002] There is known a drilling apparatus for drilling a workpiece such as a printed circuit board with a drill. For example, Patent Document 1 discloses a hole punching device including a table, a main shaft that can be rotated up and down to hold a tool for processing a printed circuit board placed on the table, and a pressing device that When processing the printed circuit board, the printed circuit board is pressed against the table. [0003] Generally, a hole drilling apparatus performs hole drilling processing on a workpiece in a state where the workpiece is pressed toward the drill side by a support member from the side opposite to the drill. The support member is provided to be replaceable. When using the support member for the first time after replacing the support member, drill the support member together with the workpiece with a drill. Every time the hole dr...
