detailed description

The invention will be described in further detail below in conjunction with the accompanying drawings. The invention is a disc-type tool magazine for a horizontal machining center, which has a tool magazine body, a tool conveying mechanism matched with the tool magazine body, and a tool changing mechanism.

As shown in Figure 1 and Figure 3, the specific structure of the tool magazine body created by the present invention is: a disk 1 is installed on the fixed bracket I5, the disk 1 can rotate around its own center through the rotating shaft, and several Each tool holder 2 is parallel to the axis of the disc 1 and evenly distributed along the edge of the disc 1 . The axis of the tool holding part of the tool holder 2 is parallel to the disc surface of the disc 1, so that after the tool 3 is installed on the tool holder 2, the axis of the tool 3 is parallel to the disc surface of the disc 1, and the tool 3 passes through the tool holding part on the tool holder 2 Installed on the disk 1, and the tip of the cutter 3 points to the center of the disk 1, since the axis of the cutter 3 is parallel to the disk surface of the disk, the width of the tool magazine body is not limited by the length of the cutter 3, and can be further compressed; The disk 1 is driven to rotate by the servo motor I4, and the rotation angle of the disk 1 is controlled to make the designated tool 3 rotate to the designated position. The tool magazine body is connected to the side of the bed of the horizontal machining center by screws through the fixed bracket I5, and the axis of the disc 1 is parallel to the X axis of the horizontal machining center.

As shown in Figure 2 and Figure 4, there is also a tool delivery mechanism installed on the fixed bracket II18, with a servo motor II6, the servo motor II6 is fixed on the fixed bracket II18 above the support frame I15 by screws, and a linear guide rail I16 is installed below the support frame I15 , the slide plate 17 is installed on the slider I of the linear guide rail I16, the ball screw 10 is installed on the slide plate 17, and one end of the ball screw 10 is equipped with a synchronous belt pulley II9, which passes through the synchronous pulley I7 installed on the shaft end of the servo motor II6 The synchronous belt 8 transmits torque, and the servo motor II6 rotates the ball screw 10 through the synchronous belt 8, thereby driving the slide plate 17 to move along the axis direction of the disc 1 (that is, the X-axis direction of the machining center), ensuring that the tool 3 is transported to the tool change point; The lower end surface of the slide plate 17 is equipped with a linear guide rail II11, and the tool holder seat 12 is installed on the slide block II of the linear guide rail II11, and an air cylinder 19 is installed below the slide plate 17, which is used to drive the tool holder seat 12 to extend parallel to the surface of the disc 1. Pointing to the direction of the center of the disc 1 (that is, the direction of the Z axis of the machining center) to realize the action of the tool holder moving forward to grab the knife; the tool holder seat 12 is also equipped with a rotary cylinder 13, and the tool holder 14 is installed on the rotary cylinder 13 to realize the movement of the tool holder 90 degrees of rotation of 14, the tool holder 14 is rotated by the Z-axis direction of the machining center and the Y-axis direction of the machining center, and when the tool holder 14 is downward in the Y-axis direction, it waits for the manual upper knife. This tool conveying mechanism can realize the independent drive of three directions: one, be parallel with disc 1 and point to disc 1 circle center direction (being the Z-axis direction of machining center) driven by cylinder 19; Two, the axis direction of disc 1 ( That is, the X-axis direction of the machining center) is driven by the servo motor II6; 3.
