Embodiment Construction
[0009] like figure 1 , 3 As shown: 1 is the tool magazine of the machining center, and the tool magazine 1 is fixedly connected to the tool magazine support 2 . 10 is two parallel side supports that are fixedly connected with the bed body, and is slidably connected with a tool change protection door 9 with the side support 10 bottom. The both sides of tool changing protective door 9 are fixed with guide rail 11, and the slide block 12 that matches with guide rail 11 is fixed on side support 10 bottoms, guarantees that good sliding is arranged between tool changing protective door 9 and side support 10.
[0010] The connecting rod bracket 4 is fixedly connected with the bed body; the tool magazine bracket 2 is rotationally connected with one end of the first connecting rod 3 through the first pin shaft 13, and the other end of the first connecting rod 3 is connected with the second connecting rod through the third pin shaft 14. Rod 6 is rotatably connected, one end of second ...

The invention provides a planar linking mechanism of a tool-changing protection door. The planar linking mechanism of the tool-changing protection door comprises tool changer supports fixedly connected with a tool changer, two parallel side supports fixedly connected with a lathe bed, and the tool-changing protection door slidably connected with the lower edges of the side supports. Connecting-rod supports are fixedly connected with the lathe bed. Each tool changer support is rotatably connected with one end of a first connecting rod through a first hinge pin, and the other end of each first connecting rod is rotatably connected with a second connecting rod through a third hinge pin. One end of each second connecting rod is rotatably connected with the corresponding connecting-rod support through a second hinge pin, and the other end of each second connecting rod is rotatably connected with one end of a third connecting rod through a fourth hinge pin. The other end of each third connecting rod is rotatably connected with a tool-changing protection door support through a fifth hinge pin. Each tool-changing protection door support is fixedly connected with the tool-changing protection door. The two sets of tool changer supports, first connecting rods, second connecting rods, third connecting rods, connecting-rod supports and tool-changing protection door supports are arranged in parallel. By adoption of the planar linking mechanism of the tool-changing protection door, the tool changing time is shortened, meanwhile, the number of hydraulic or pneumatic links in the prior art is reduced, and the reliability is improved.
Description
technical field [0001] The invention relates to a plane linkage mechanism, in particular to a plane linkage mechanism of a tool change protection door. Background technique [0002] The high-speed performance of machine tools is an important indicator to improve market competitiveness. At present, when the machine tool of the machining center is performing the tool change action, the tool magazine connected to the tool magazine bracket will move down under the drive of the driving parts, and at the same time, the tool change protection door will move horizontally and open, and the tool change will be performed in the tool change area. , and return to their respective positions after tool change. The protective door is opened horizontally, the tool magazine moves down, and the return position after the tool change is completed is driven by two drive components respectively. In this process, it is not only necessary to control the time sequence of the tool magazine moving do...
