The rolling curtain protection assembly 7 is arranged between the processing mechanism 3 and the bridge plate 21 and is mainly used for separating the processing mechanism 3 from the bridge plate 21 so as to prevent scraps, cutting fluid and the like generated in the processing process from splashing to one side of the processing mechanism 3 when the main shaft 31 is used for processing a workpiece, and further influence some components and parts, an electric control device and the like of the processing mechanism 3. The roller shutter protection assembly 7 separates the processing mechanism 3 from the bridge plate 21, but a main shaft 31 of the processing mechanism 3 needs to process a workpiece, so that the roller shutter protection assembly 7 is provided with a position for the main shaft 31 to pass through, and the main shaft 31 can pass through the roller shutter protection assembly 7 to extend into one side of the bridge plate 21 in a processing state. When the main shaft 31 does not process the workpiece, the main shaft 31 can be completely retracted to the side where the processing mechanism 3 is located, so that the main shaft 31 does not penetrate through the roller shutter protection assembly 7, the main shaft 31 can be better protected, and the damage to the main shaft 31 during workpiece loading and unloading is avoided; of course, the main shaft 31 may be maintained in a state of passing through the shutter guard assembly 7 when the main shaft 31 does not machine the workpiece. Being provided with roll up curtain protection component 7 can significantly reduce in the course of working and produce sweeps and cutting fluid etc. and splash to the processing agency 3 to avoid influencing the normal operating (like removing, control etc.) of processing agency 3.
Further, the rolling shutter protection assembly 7 comprises an X-axis protection framework 71, a Y-axis protection framework 72 and a Z-axis protection framework 73; the X-axis protective framework 71 is installed on the lathe bed 1, the Y-axis protective framework 72 is slidably installed on the X-axis protective framework 71, the Z-axis protective framework 73 is slidably installed on the Y-axis protective framework 72, and the spindle box 34 penetrates through the Z-axis protective framework 73 to enable the spindle 31 to be located on one side where the multi-station fixture mechanism is located; the X-axis protective framework 71, the Y-axis protective framework 72 and the Z-axis protective framework 73 are all provided with flexible roller shutters 74.
Since the main shaft 31 is required to move in the XYZ-axis direction during the processing of the workpiece, the rolling shutter protection assembly 7 is mainly used to space the processing mechanism 3 from the bridge plate 21; therefore, in order to ensure that the rolling shutter protection assembly 7 can always protect the processing mechanism 3 during the movement of the main shaft 31, the rolling shutter protection assembly 7 needs to be configured to adapt to the movement of the main shaft 31 in the XYZ axes. The rolling shutter protection component 7 comprises an X-axis protection framework 71, a Y-axis protection framework 72 and a Z-axis protection framework 73; the X-axis protective framework 71 is arranged on the bed body 1 and can define the moving direction of the saddle 32 as the X-axis direction; the Y-axis protective framework 72 is slidably arranged on the X-axis protective framework 71, and flexible roller shutters 74 are arranged on two sides of the X-axis protective framework 71 on the Y-axis protective framework 72; the Z-axis protective framework 73 is slidably arranged on the Y-axis protective framework 72, and the Y-axis protective framework 72 is arranged on the flexible roller shutters 74 at the upper side and the lower side of the Z-axis protective framework 73; the main spindle box 34 penetrates through a Z-axis protective framework 73 to enable the main spindle 31 to be located on one side of the bridge plate 21, and a flexible roller shutter 74 is installed on the Z-axis protective framework 73. When the spindle 31 moves in the X-axis direction, that is, the saddle 32 approaches or leaves the bridge plate 21, the spindle box 34 performs a plugging operation with respect to the Z-axis protective framework 73; when the main shaft 31 moves in the Y-axis direction, that is, the Y-axis protective framework 72 moves relative to the X-axis protective framework 71, one side of the flexible roller shutters 74 on both sides of the Y-axis protective framework 72 is compressed, and the other side is stretched; when the main shaft 31 moves in the Z-axis direction, that is, the Z-axis protective frame 73 moves up and down relative to the Y-axis protective frame 72, one side of the flexible roller blinds 74 on the upper and lower sides of the Z-axis protective frame 73 is compressed, and the other side is stretched. Therefore, scraps, cutting fluid and the like generated in the workpiece machining process can be blocked by the flexible roller shutter 74 in the splashing process, and cannot splash to one side of the machining mechanism 3, so that the protection of the flexible roller shutter 74 to the machining mechanism 3 is ensured, and the influence of the scraps and the like on the normal operation of the machining mechanism 3 is avoided.
