Embodiment approach 1

[0032] Such as figure 1 , figure 2 As shown, the machine tool includes a base 1 , an XY-axis moving device 2 , a workbench 3 , a Z-axis moving device 4 , a tool magazine 5 and a control device 6 . The XY axis moving device 2 is disposed on the upper surface of the base 1 . The workbench 3 is assembled on the XY axis moving device 2 . The table 3 moves left and right (X axis direction) and front and rear (Y axis direction) under the drive of the XY axis moving device 2 . The base 1 has uprights 7 . The column 7 extends upward behind the XY axis moving device 2 . The column 7 has a frame 8 at the top. The frame 8 extends forward on the left and right sides of the column 7 . The frame 8 supports the tool magazine 5 at the front end. The control device 6 is mounted on the rear of the column 7 . The Z-axis moving device 4 is arranged on the front part of the column 7 . Such as image 3 As shown, the Z-axis displacement device 4 is provided with a spindle head 10 at the f...

Embodiment approach 2

[0048] Such as Figure 8 As shown, the machine tool according to Embodiment 2 has a restricting device 90 . The restricting device 90 has a rotation gear 91 (engagement gear), a shaft 92 and a support body 95 . The shaft 92 has a coaxial large-diameter portion 92a. The diameter of the large-diameter portion 92 a is larger than the diameter of other portions of the shaft 92 . The large-diameter portion 92 a is accommodated in an accommodation chamber 95 a provided in the support body 95 . The accommodation chamber 95a has bearings 94 on the upper and lower sides of the large-diameter portion 92a, respectively. Each bearing 94 supports the shaft 92 . The shaft 92 is rotatable about an axis in the vertical direction. The lower end portion of the shaft 92 protrudes below the support body 95 . The rotary gear 91 is fitted to the lower end of the shaft 92 . The rotary gear 91 rotates together with the shaft 92 . The large-diameter portion 92a has a plurality of concave porti...

Embodiment approach 3

[0054] Such as Figure 11 As shown, the machine tool according to Embodiment 3 has a restricting device 90A. The restricting device 90A includes a rotation gear 91A (engagement gear), a shaft 92A, and a support body 95A. The shaft 92A has a coaxial large-diameter portion 92Aa and a middle-diameter portion 92Ac. The diameter of the large-diameter portion 92Aa is larger than the diameter of the middle-diameter portion 92Ac. The diameter of the middle diameter portion 92Ac is larger than the diameter of the portion of the shaft 92A other than the large diameter portion 92Aa and the middle diameter portion 92Ac. The large-diameter part 92Aa and the middle-diameter part 92Ac are housed in a storage chamber 95Aa provided in the support body 95A. The accommodation chamber 95Aa has bearings 94 above the large-diameter portion 92Aa and below the middle-diameter portion 92Ac. Two bearings 94 support the shaft 92A. The shaft 92A is rotatable about an axis in the vertical direction. ...

Abstract

The invention relates to a machine tool capable of using turning cutter by maintaining universality of a cutter handle. The machine tool comprises a main spindle nose used for maintaining a main spindle, a driving source used to drive the main spindle to rotate around the axis, a cutter warehouse used for accommodating the cutter, a main spindle gear disposed on the main spindle, and a transmission gear disposed on the cutter warehouse. The transmission gear is used to transmit the rotation of the main spindle to the cutter warehouse by being engaged with the main spindle gear. The main spindle nose is provided with a limiting part, which is used to limit the rotation of the main spindle by being clamped with the main spindle gear, and the limiting part is provided with a clamping gear clamped with the main spindle gear and a limiting mechanism used to limit the rotation of the clamping gear. The limiting mechanism is used to limit the rotation of the clamping gear, and then the main spindle cannot rotate, and therefore the machine tool can use the turning cutter by using the common cutter handle for the processing.

Description

technical field [0001] The invention relates to a machine tool with a tool magazine. Background technique [0002] The machine tool processes a workpiece fixed on a table with a tool mounted on a spindle. The tool is stored in the tool magazine via the tool holder. The spindle exchanges tools between itself and the tool magazine by ascending and descending. The tool is moved to the exchange position by the rotation of the magazine. [0003] The machine tool described in Japanese Laid-Open Patent Publication No. 2012 061526 has a tool magazine that rotates under the drive of the main shaft. The tool magazine has a tool magazine gear provided on the rotary shaft. The main shaft has a main shaft gear at the lower end. The main shaft gear meshes with the magazine gear when the main shaft is raised. The rotation of the main shaft is transmitted to the tool magazine by means of the main shaft gear and the tool magazine gear. [0004] Knives include rotary tools and turning ...
