Abstract

(57) [Summary] [Purpose] To provide a broaching machine that occupies a small area and is short. [Structure] Head 1 for guiding broach 22 in the longitudinal direction
A frame 4 on which a broach guide mechanism including a guide bar 6, a ball screw 8, and a feed motor 10 for driving the guide mechanism is installed is attached to the frame 2 at an angle of about 45 degrees. There is.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a broaching machine.

[0002]

[Prior art]

 A horizontal broaching machine in which the frame of the broaching machine is arranged laterally with respect to the floor surface is disclosed in Japanese Utility Model Publication No. 55-75412. A vertical broaching machine in which the frame of the broaching machine is arranged in the vertical direction with respect to the floor is disclosed in Japanese Utility Model Laid-Open No. 154015/1983.

[0003]

[Problems to be solved by the device]

 This type of broaching machine is generally large and slender and has a total length of 6 meters. With the advent of the ball screw type, the overall length has become somewhat shorter, but it is still quite large. As a result, the horizontal broaching machine occupies a large area, and there is a defect that imposes great restrictions on the layout within the factory. In addition, the vertical broaching machine has a defect that the height of the broaching machine becomes large and the broaching hits the ceiling or is difficult to handle in operation. The present invention aims to eliminate the above defects.

[0004]

[Means for solving problems]

 In order to achieve the above object, the present invention provides a broaching machine including a frame having a guide mechanism for guiding the broach in its longitudinal direction and a drive mechanism for driving the guide mechanism, and a pedestal mounted on the floor. In the above, the frame is supported on the gantry with an inclination angle of about 45 degrees.

[0005]

[Action]

 Since the entire broaching machine is inclined at 45 degrees, the height of the entire broaching machine can be reduced, the operation is facilitated, and the occupied area can be reduced.

[0006]

【Example】

 Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. Reference numeral 2 is a gantry, which is placed on the floor via casters (not shown) or the like. The lower end of the frame 4 is fixed to one side of the gantry 2 with an inclination angle of 45 degrees.

At both ends of the frame 4, guide bars 6 are installed between side walls 4 a and 4 b fixed vertically to the frame 4. Further, a ball screw 8 is rotatably supported between the side walls 4a and 4b. A feed motor 10 is fixed to the frame 4 via a bracket, and its output shaft is linked to the ball screw 8 via gears 12, 14 and 16.

Reference numeral 18 is a head provided with a ball nut 20, which is slidably fitted in the guide bar 6 and a broach 22 is connected thereto. The ball nut 20 of the head 18 is screwed onto the ball screw 8. Reference numeral 24 is a work holder, and 26 is a work.

The head 18, the guide bar 6 and the ball screw 8 constitute a guide mechanism for guiding the broach 22 in its longitudinal direction, and the feed motor 10 and the gears 12, 14, 16 drive the guide mechanism. It constitutes the mechanism.

In the above structure, the head 18 moves along the guide bar 6 by driving the feed motor 10, and the broach 22 moves in conjunction with the movement of the head 18 to cut the work 26.

[0011]

【effect】

 According to the present invention, as described above, the frame of the broaching machine is tilted at 45 degrees with respect to the frame, and the broach supported by the frame is reciprocally moved in the longitudinal direction while being tilted at 45 degrees with respect to the floor surface. Therefore, compared to a horizontal broaching machine, the occupying area of the gantry can be made smaller, and the height of the broach can be made lower than that of a vertical broaching machine, which makes it easier to handle. Exist.
