Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0050] figure 1 It is a front sectional view of the tool holder in the printed circuit board processing machine related to the present invention, and it is related to Figure 4 The same parts or parts with the same function are marked with the same symbols, and repeated explanations are omitted.

[0051] The tool holder 50 according to the present invention is composed of a sleeve 51 , a seat body 60 , a collar 61 , a first spring 53 and a second spring 62 .

[0052] The sleeve 51 is erected and fixed to the table 1 by a mechanism not shown in the figure.

[0053] Inside the sleeve 51 are formed a small-diameter portion 51a opened toward the upper end side in the axial direction, a middle-diameter portion 51b coaxially connected to the end of the small-diameter portion 51a and having a diameter larger than the small-diameter portion, and the same diameter as the midd...

Abstract

The invention provides a tool rest for a printed circuit board processing machine, which can make the axis of a tool coaxial with the axis of a spring collet and includes a sleeve (51), a seat body (60) which forms a slit (60t) on the upper end to maintain the tool and is freely movable inside the sleeve (51), a socket ring (61) equipped inside the sleeve (51), a first spring (53) and a second spring (62) whose elastic coefficient is less than that of a first spring (53), wherein the second spring (62) is equipped between the seat body (60) and the socket ring (61); the first spring (53) is equipped on the lower side of the socket ring (61); when the tool (31) is loaded on the seat body (60) and moves within a distance (m), the seat body (60) applies a force to the spring collet by means of an action force of the second spring (62); and when the tool moves beyond the distance (m) the slit (60t) is widened by the action force of the first spring (53).

Description

technical field [0001] The present invention relates to a tool holder of a printed circuit board processing machine for temporarily holding a tool to be used in processing such as drilling or a tool used in processing in the printed circuit board processing machine. Background technique [0002] figure 2 It is a perspective view of a conventional printed circuit board processing machine, image 3 yes figure 2 The main part of the main view, Figure 4 is the front sectional view of the tool holder. [0003] exist figure 2 Among them, on the workbench 1 of the printed circuit board processing machine 100, a printed circuit board 2, a tool box 4 holding a plurality of tools (here, drills) 3 such as drills, two tool holders 5, and a tool head end detection device are placed. 6. The table 1 is supported by a pair of guide devices 8 placed on the bed 7 . Such as image 3 As shown, the nut 9 fixed on the table 1 below is screwed with the feed screw 10 . The feed screw 10 i...
