Abstract
Description
Technical Field
[0001] This application relates to the technical field of machining centers, and in particular to a tool changing and positioning device for machining centers. Background Technology
[0002] CNC milling machines are automated machining equipment developed from general milling machines. The machining processes are basically the same, and their structures are somewhat similar. CNC milling machines are divided into two main categories: those without a tool magazine and those with a tool magazine. CNC milling machines with a tool magazine are also known as machining centers. Regarding the related technologies mentioned above, the inventors believe that the tool magazine has a limited number of tools, requiring head changes, which is relatively cumbersome. Utility Model Content
[0003] To facilitate tool changing, this application provides a tool changing positioning device for machining centers.
[0004] The tool changing and positioning device for a machining center provided in this application adopts the following technical solution:
[0005] A tool changing and positioning device for a machining center includes a worktable, a first linear slide, a tool mounting bracket, a second linear slide, a spindle, and a third linear slide. Two sets of the first linear slides are provided, extending along the length of the worktable. The tool mounting bracket is positioned between the two sets of the first linear slides. Mounting plates are provided on both sides of the worktable in the width direction. The second linear slide is positioned between two mounting plates. The third linear slide is positioned on the second linear slide, and the spindle is positioned on the third linear slide.
[0006] With the above technical solution, when a tool change is required, the first linear slide is activated and moves to the underside of the spindle. The second linear slide is then activated, moving the spindle to the tool mounting bracket. Subsequently, the third linear slide is activated, moving the spindle downwards. The spindle then releases the tool and places it on the tool holder. The third linear slide is then activated again, moving the spindle upwards. The second linear slide is then activated, sliding to the designated tool position. Finally, the third linear slide is activated, moving the spindle downwards, and the spindle clamps the tool, facilitating tool change.
[0007] Optionally, the tool mounting bracket includes a mounting plate and multiple mounting blocks, the multiple mounting blocks being evenly spaced along the length of the mounting plate, and each mounting block having a fixing hole for inserting a tool.
[0008] The above technical solution allows for the placement of multiple different types of cutting tools within the mounting block, facilitating tool replacement.
[0009] The beneficial effects of this utility model are as follows: When a tool change is required, the first linear slide is activated and moves to the lower side of the spindle. The second linear slide is activated and moves the spindle to the tool mounting bracket. Then, the third linear slide is activated and moves the spindle downward. The spindle then releases the tool and places it on the tool mounting bracket. The third linear slide is then activated and moves the spindle upward. The second linear slide is then activated and slides to the designated tool position. The third linear slide is then activated and moves the spindle downward. The spindle clamps the tool, which facilitates tool change. Attached Figure Description

[0012] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.
[0013] This application discloses a tool changing and positioning device for a machining center.
[0014] Reference Figure 1 The machining center tool changing and positioning device includes a worktable 1, a first linear slide 2, a tool mounting bracket 3, a second linear slide 4, a spindle 5, and a third linear slide 6. The first linear slide 2 is provided in two sets, which extend along the length of the worktable 1. The tool mounting bracket 3 is located between the two sets of first linear slides 2. Mounting plates 31 are provided on both sides of the worktable 1 in the width direction. The second linear slide 4 is located between the two mounting plates 31. The third linear slide 6 is located on the second linear slide 4, and the spindle 5 is located on the third linear slide 6.
[0015] When a tool change is needed, the first linear slide 2 is activated, moving it to the underside of the spindle 5. The second linear slide 4 is then activated, moving the spindle 5 onto the tool holder 3. Subsequently, the third linear slide 6 is activated, moving the spindle 5 downwards. The spindle 5 then releases the tool, placing it on the tool holder. The third linear slide 6 is then activated again, moving the spindle 5 upwards. The second linear slide 4 is then activated, sliding to the designated tool position. The third linear slide 6 is then activated, moving the spindle 5 downwards. The spindle 5 then grips the tool, facilitating tool change.
[0016] The tool mounting bracket 3 includes a mounting plate 31 and multiple mounting blocks 32. The multiple mounting blocks 32 are evenly spaced along the length of the mounting plate 31, and the mounting blocks 32 are provided with fixing holes 321 for inserting tools.
[0017] Multiple different types of cutting tools can be placed inside the mounting block 32 for easy tool replacement.
[0018] The implementation principle of the tool changing and positioning device for a machining center according to an embodiment of this application is as follows: When a tool change is required, the first linear slide 2 is activated and moves to the lower side of the spindle 5. The second linear slide 4 is activated, driving the spindle 5 to the tool mounting bracket 3. Then, the third linear slide 6 is activated, driving the spindle 5 to move downward. The spindle 5 then releases the tool and places it on the tool mounting bracket. The third linear slide 6 is then activated again, driving the spindle 5 to rise. The second linear slide 4 is then activated and slides to the designated tool position. The third linear slide 6 is then activated, driving the spindle 5 to descend. The spindle 5 clamps the tool, facilitating tool changing.
[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
