Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to an umbrella-shaped tool changer. Background Technology
[0002] Tool magazines are an indispensable component of CNC machine tools, providing tool storage and changing capabilities during automated machining processes, significantly shortening machining time and reducing production costs. Tool magazines generally come in several forms, including umbrella-type, rotary-type, and chain-type tool magazines.
[0003] For example, the patent document with publication number CN202877991U discloses an improved umbrella-type tool magazine structure for CNC machine tools, including an umbrella-type tool magazine and a servo motor. The outer edge of the tool disc of the umbrella-type tool magazine is provided with tool claws for fixing the tool. The umbrella-type tool magazine is also provided with a fixed base. The tool disc is rotatably mounted on the fixed base through a central rotating shaft and bearings. The output end of the servo motor is connected to the tool disc or the central rotating shaft through a gear transmission mechanism. The servo motor drives the tool disc to rotate, thereby rotating the tool to be changed to the tool changing position, and the tool can be changed through the tool changing device.
[0004] Although umbrella-shaped tool magazines facilitate tool changing through their structure, they are usually fixed and difficult to move. Therefore, when changing tools, the tool holder needs to be moved to the tool magazine position, and then moved back to its original position after the tool change. This process can easily cause the tool holder to shift, which can be inconvenient for machining the workpiece. Utility Model Content

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0036] This utility model embodiment provides an umbrella-shaped tool changer magazine for installing various types of cutting tools 10a, which can be called up at any time during machine tool machining, and the cutting tools 10a can be called up without moving the tool holder, thus solving the technical problem in the prior art that the machine tool tool holder is prone to displacement during tool changing.
[0037] like Figure 1-3 As shown, the umbrella-shaped tool changer of this utility model embodiment includes a fixed base 10, a mounting frame 20, a turntable 30, several tool claws 40, a rotary drive module 50, and a sliding drive module 60. The mounting frame 20 is slidably connected to the fixed base 10; the turntable 30 is rotatably connected to the mounting frame 20; each tool claw 40 is fixed at intervals along the circumferential direction of the turntable 30 and is used to install different tools 10a respectively; the rotary drive module 50 is mounted on the mounting frame 20 and connected to the turntable 30, and is used to drive the turntable 30 to rotate; the sliding drive module 60 is connected to the mounting frame 20, and is used to drive the mounting frame 20 to slide.
[0038] Specifically, the tool changer consists of a fixed base 10, a mounting bracket 20, a turntable 30, several tool claws 40, a rotary drive module 50, and a sliding drive module 60. The tool changer is fixed to the machine tool via the fixed base 10. The mounting bracket 20 is slidably connected to the fixed base 10. The turntable 30 is rotatably connected to the mounting bracket 20. Each tool claw 40 is fixed at intervals along the circumference of the turntable 30. The sliding drive module 60 is connected to the mounting bracket 20 and can drive the mounting bracket 20 to slide along the fixed base 10, thereby moving the tool 10a mounted on the tool claw 40 to the tool post of the machine tool. With the above configuration, when changing the tool 10a, the rotary drive module 50 drives the turntable 30 to rotate, causing the tool post to be changed to rotate to the tool changing position. The sliding drive module 60 drives the mounting bracket 20 to slide, causing the tool 10a to move to the tool post of the machine tool. Then, the tool can be changed through the tool post, eliminating the need to move the tool post during the tool changing process, effectively avoiding tool post offset, and facilitating the machining of the workpiece.
[0039] Understandably, the mounting base 10 can be any mounting structure that can be fixed to the machine tool frame.
[0040] Understandably, the mounting bracket 20 can be slidably connected to the mounting bracket 10 by providing a sliding rod, or by providing a sliding groove, the mounting bracket 20 can be slidably connected to the mounting bracket 10.
[0041] In one embodiment, the fixing base 10 is a plate 22, such as Figure 1-2As shown, to enable the mounting bracket 20 to slide along the fixed base 10, the fixed base 10 is provided with a slide rail 11, and the mounting bracket 20 is provided with a slider 21. The mounting bracket 20 is slidably connected to the slide rail 11 via the slider 21. Specifically, through the cooperation between the slider 21 and the slide rail 11, the mounting bracket 20 can slide stably along the fixed base 10.
[0042] In this embodiment, the slide rail 11 extends in the horizontal direction of the machine tool.
[0043] In one embodiment, such as Figure 1 As shown, the fixed base 10 is provided with a straight groove 12. Specifically, the fixed base 10 can be fixed by spirally threading the straight groove 12 and connecting it to a machine tool, and the straight groove 12 can adjust the installation position.
[0044] Understandably, the mounting frame 20 can be any frame structure that allows the turntable 30 to rotate.
[0045] In one embodiment, such as Figure 1 As shown, the mounting frame 20 includes a plate 22, a mounting base 23, and a rotary feeder 24. The plate 22 is slidably connected to the fixed base 10. The mounting base 23 and the rotary feeder 24 are respectively fixed to the upper and lower ends of the plate 22. The rotary drive module 50 is fixed to the mounting base 23, and the turntable 30 is rotatably connected to the rotary feeder 24. Specifically, the mounting frame 20 achieves a slidable connection with the fixed base 10 through the plate 22. The mounting base 23 and the rotary feeder 24 are respectively used for connecting the rotary drive module 50 and the turntable 30. The mounting base 23 and the rotary feeder 24 are arranged opposite to each other, which facilitates the connection between the rotary drive module 50 and the turntable 30, thereby facilitating the drive of the turntable 30 by the rotary drive module 50.
[0046] In one embodiment, such as Figure 1 and 3 As shown, the rotary drive module 50 includes a motor 51 and a coupling 52. The motor 51 is fixed to the mounting base 23, and the coupling 52 is fixed to the shaft of the motor 51 and connected to the turntable 30. Specifically, the motor 51 is connected to the turntable 30 through the coupling 52, thereby driving the rotation of the turntable 30 and realizing the changing of the tool 10a.
[0047] In one embodiment, such as Figure 1 and 3 As shown, the turntable 30 is equipped with a rotating shaft 31, and the feed seat 24 is equipped with spaced bearings 241. The rotating shaft 31 is fixed to the inner ring of the bearings 241 and is rotatably connected to the feed seat 24 through the bearings 241. Specifically, the rotation drive module 50 achieves connection with the turntable 30 through the rotating shaft 31, and the rotating shaft 31 can achieve rotatable connection with the feed seat 24 through the bearings 241.

Through the spacing of the spacer ring 242, the spaced bearings 241 can be limited and supported, thereby improving the stability of the bearings 241 and ensuring the stable rotation of the rotating shaft 31.
[0049] In one embodiment, such as Figure 1 and 3 As shown, the rotating base 24 is also provided with a pressure cap 243, which is sleeved on the rotating shaft 31 and pressed against the outer ring of the upper bearing 241. Specifically, by pressing the upper bearing 241, the pressure cap 243 further limits the upper bearing 241, thereby improving the stability of the bearing 241 and ensuring the stable rotation of the rotating shaft 31.
