Description

Technical Field

[0001] This utility model relates to the technical field of tool magazine changing slide saddle assemblies, and in particular to a movable tool magazine changing slide saddle assembly. Background Technology

[0002] As a key functional component for automated machining in CNC machining centers, the tool magazine primarily undertakes the task of spindle tool changing, which is crucial for ensuring process continuity and improving machining efficiency. In traditional structural designs, the tool magazine is usually fixed to one side of the machine tool, and a tool-changing robotic arm reciprocates between the tool magazine and the spindle to complete the tool grabbing, exchanging, and clamping actions. However, this structure has significant drawbacks, such as long motion paths and numerous action steps, leading to increased time consumption for each tool change. Especially in machining scenarios with multiple processes and frequent tool changes, frequent tool changes significantly extend non-cutting time, thereby reducing overall tool changing efficiency, ultimately resulting in longer workpiece machining cycles, affecting equipment utilization and production capacity.

[0003] To address the aforementioned issues, the industry is actively developing new tool magazine systems such as servo direct drive, tool head linkage, and dynamic tool tracking to shorten tool change paths, reduce mechanical movements, and thus improve overall equipment performance. Summary of the Invention

[0004] The technical problem this utility model aims to solve is: In order to address the issue that traditional tool magazines are usually fixedly installed on one side of the machine tool, and the tool changing robot arm reciprocates between the tool magazine and the spindle to complete the tool grabbing, exchanging and clamping actions, in machining scenarios with multiple processes and frequent tool switching, frequent tool changing operations will significantly extend the non-cutting time, thereby reducing the overall tool changing efficiency, and ultimately causing the workpiece machining cycle to be extended, affecting equipment utilization and production capacity. The present invention provides a movable tool magazine tool changing slide saddle assembly.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a movable tool magazine changing saddle assembly, including a saddle and a tool magazine assembly and a tilting head assembly disposed on the saddle. Both the tool magazine assembly and the tilting head assembly are slidably disposed on the saddle along the Z-axis direction. The tool magazine assembly and the tilting head assembly are arranged opposite to each other. A first driving mechanism and a second driving mechanism are disposed on the saddle. The first driving mechanism is used to drive the tool magazine closer to or away from the tilting head assembly, and the second driving mechanism is used to drive the tilting head assembly closer to or away from the tool magazine assembly. Compared with the prior art, this solution, by using the first driving mechanism and the second driving mechanism to drive the tool magazine assembly and the tilting head assembly closer to or away from each other respectively, allows the tool changing point to move with the spindle machining, achieving dynamic tool changing, improving tool changing efficiency, saving tool changing waiting time, and thus reducing machining time.

[0006] To implement the first driving mechanism, in some preferred embodiments, the first driving mechanism includes a spindle box assembly and a spindle box motor. The spindle box assembly is slidably mounted on a slide saddle along the Z-axis direction. A first screw is rotatably mounted on the slide saddle. The spindle box assembly is threadedly connected to the first screw. The oscillating head assembly is mounted on the spindle box assembly. The spindle box motor is fixedly mounted on the slide saddle, and the output end of the spindle box motor is threadedly connected to the first screw. By driving the first screw to rotate through the spindle box motor, the spindle box assembly can be driven to slide along the Z-axis direction on the slide saddle, thereby displacing the oscillating head assembly.

[0007] To enable the spindle box assembly to slide on the slide saddle, in some preferred embodiments, a first linear guide rail is provided on the slide saddle, and a first slider is provided on the spindle box assembly. The first slider is slidably mounted on the first linear guide rail. The sliding of the spindle box assembly on the slide saddle is achieved through the cooperation of the first linear guide rail and the first slider.

[0008] To implement the second drive mechanism, in some preferred embodiments, the second drive mechanism includes a tool magazine motor, a second screw is rotatably mounted on the slide saddle, and the tool magazine assembly is threadedly connected to the second screw.

[0009] In some preferred embodiments, the spindle box motor is mounted on the slide saddle via a motor support.

[0010] In order to enable the tool magazine assembly to slide on the slide saddle, in some preferred embodiments, the slide saddle is provided with a second linear guide rail, the tool magazine assembly is provided with a second slider, and the second slider is slidably disposed on the second linear guide rail.

[0011] To better control the proximity or distance between the tool magazine assembly and the tilting head assembly, in some preferred embodiments, the first linear guide rail and the second linear guide rail are arranged parallel to each other. Arranging the first and second linear guide rails parallel to each other prevents interference between the tool magazine assembly and the tilting head assembly, thus avoiding unnecessary problems.

[0012] The beneficial effects of this utility model are as follows: When in use, the movable tool magazine and tool changer saddle assembly of this utility model are driven to move closer or further apart by the first drive mechanism and the second drive mechanism, respectively, so that the tool change point can move with the spindle machining to achieve dynamic tool change, improve tool change efficiency, save tool change waiting time, and thus reduce machining time. This avoids the problem that traditional tool magazines are usually fixed on one side of the machine tool, and the tool changer arm moves back and forth between the tool magazine and the spindle to complete the tool grabbing, exchanging and clamping actions. In machining scenarios with multiple processes and frequent tool switching, frequent tool change operations will significantly prolong non-cutting time, thereby reducing the overall tool change efficiency, and ultimately causing the workpiece machining cycle to be extended, affecting equipment utilization and production capacity.

[0016] like Figure 1-7 As shown, a movable tool magazine changing saddle assembly 4 includes a saddle 4, a tool magazine assembly 1, and a tilting head assembly 2. Both the tool magazine assembly 1 and the tilting head assembly 2 are slidably mounted on the saddle 4 along the Z-axis direction. The tool magazine assembly 1 and the tilting head assembly 2 are arranged opposite to each other. The saddle 4 is provided with a first driving mechanism and a second driving mechanism. The first driving mechanism is used to drive the tool magazine to move closer to or away from the tilting head assembly 2, and the second driving mechanism is used to drive the tilting head assembly 2 to move closer to or away from the tool magazine assembly 1. In this embodiment, the Z-axis direction is the vertical direction.

[0017] The first drive mechanism includes a spindle box assembly 3 and a spindle box motor 11. The spindle box assembly 3 is slidably mounted on a slide saddle 4 along the Z-axis. A first screw 9 is rotatably mounted on the slide saddle 4. The spindle box assembly 3 is threadedly connected to the first screw 9. The oscillating head assembly 2 is mounted on the spindle box assembly 3. The spindle box motor 11 is fixedly mounted on the slide saddle 4. The output end of the spindle box motor 11 is threadedly connected to the first screw 9. A first linear guide rail 8 is provided on the slide saddle 4. A first slider is provided on the spindle box assembly 3. The first slider is slidably mounted on the first linear guide rail 8.

[0018] The second drive mechanism includes a tool magazine motor 10, a second screw 7 rotatably mounted on a slide saddle 4, a tool magazine assembly 1 threadedly connected to the second screw 7, a spindle box motor 11 mounted on the slide saddle 4 via a motor support 5, a second linear guide rail 6 provided on the slide saddle 4, a second slider provided on the tool magazine assembly 1, the second slider being slidably mounted on the second linear guide rail 6, and a first linear guide rail 8 and a second linear guide rail 6 being arranged parallel to each other.

[0019] Its working principle is as follows: Tool magazine assembly 1 drives tool magazine transmission assembly through tool magazine motor 10, and causes second screw 7 to rotate, which in turn causes second slider to move linearly on second linear guide rail 6. It can move downward along the Z-axis relative to swivel head assembly 2. When it reaches the tool change point, tool change can be performed. Swivel head assembly 2 and spindle box assembly 3 are driven by spindle box motor 11, and first screw 9 rotates, which causes first slider to move linearly on first linear guide rail 8. It can move upward along the Z-axis relative to tool magazine assembly 1. When it reaches the tool change point, tool change can be performed. After tool change, tool magazine assembly 1 drives tool magazine transmission assembly through tool magazine motor 10 to move linearly along tool magazine linear guide assembly. It can move upward along the axis relative to swivel head assembly 2, avoiding normal machining of swivel head assembly 2. Based on the traditional gantry, not only can spindle box assembly 3 drive swivel head assembly 2 to move, but the addition of slide saddle 4 assembly allows tool magazine assembly 1 to move with spindle box assembly 3, so that tool change point can move with spindle machining to achieve dynamic tool change, improve tool change efficiency, save tool change waiting time, and thus reduce machining time.

[0020] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
