Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Example 1:

As shown in Figure 1-3, a kind of machine tool provided by the utility model includes a base 1, a workbench 2, a feed mechanism and a tool magazine, the workbench 2 is located in the middle of the upper surface of the base 1, and the workbench 2 can be fixed The workpiece 3 can also drive the workpiece to rotate. The feed mechanism can move back and forth relative to the base 1. The feed mechanism includes a main shaft 4 and a telescopic manipulator 5. A tool 6 can be installed on the main shaft 4 and can move relative to the base 1. Move to the workbench 2 and use the tool 6 to process the workpiece 3 fixed on the workbench 2. The manipulator 5 is connected to a cylinder 7. The manipulator 5 can rotate and move up and down driven by the cylinder 7. The cylinder 7 moves with the main shaft 4 relative to the base 1.

In this embodiment, the base 1 is provided with a base 8 perpendicular to it, and the base 8 is provided with a plurality of slide rails 9, and the feed mechanism can slide along the slide rails 9, in order to prevent The feeding mechanism slides out of the base 8 . In this embodiment, the two ends of the base 8 along the direction of the slide rail 9 are respectively provided with limiting blocks 10 .

The knife magazine is installed on one side of the base 1, and one end of the base 8 is located above the knife magazine, that is, one end of the base 8 above the knife magazine is located outside the base 1. In this embodiment, the knife The library is located on the right side of the base 1, and one end of the right side of the base 8 is located outside the base 1. The tool library includes several tool holders 11, and the tool holders 11 are fixed on the first conveyor belt 12. Storehouse also comprises some workpiece fixtures 13, and described workpiece fixtures 13 are fixed on the second transmission belt 14, and tool fixture 11 and workpiece fixture 13 are arranged in the tool storehouse, can store cutting tool 6 and workpiece 3, in the present embodiment, the first transmission The belt 12 and the second conveyor belt 14 are both endless conveyor belts. Adopting the endless conveyor belt can not only increase the storage capacity of the cutting tool and the workpiece in the tool magazine, but also not increase the volume of the tool magazine excessively. When it is necessary to replace the tool or Workpieces, the first conveyor belt 12 or the second conveyor belt 14 rotates under the action of its driving device respectively, and stops when turning to the required tool 6 or workpiece 3 .

The first conveyor belt 12 is positioned above the second conveyor belt 14, the first conveyor belt 12 can be positioned right above the second conveyor belt 14, or can be arranged in a staggered manner, but when the staggered arrangement, the second conveyor belt The deviation distance between 14 and the first conveyor belt 12 in the horizontal direction should not be too large. If the distance is too large, the overall volume of the tool magazine will be too large, and the telescopic length of the manipulator 5 will be too long, which will cause the operation of the entire machine tool to be difficult. Efficiency is low, at the same time to ensure that the first transmission belt 12 is positioned at the top of the second transmission belt 14, in the present embodiment, it is directly above, so set up, it is beneficial for the main shaft 4 to replace the tool and the manipulator 5 when changing the workpiece, without any interference.

When the manipulator 5 moved up to the top under the drive of the cylinder 7, it ensured that the manipulator was above the entire tool magazine, and when it moved to the bottom, the manipulator 5 elongated and could grip the workpiece 3 located in the workpiece holder 13. The retractable manipulator 5 belongs to the prior art, and will not be repeated here.

During use, the manipulator 5 moves to the top under the drive of the cylinder 7, and the entire feed mechanism moves to the right end of the base 8, that is, above the entire tool magazine. At this time, the main shaft 4 is located above the first conveyor belt 12 , the first conveyor belt 12 rotates under the drive of its driving device until the tool 6 in the tool holder 11 below the main shaft 4 stops when it is the required tool 6, and the main shaft 4 grabs the tool 6. Since the manipulator 5 is positioned at the tool Above the library, it will not interfere with the grasping of the tool 6 by the spindle 4, and then the entire feed mechanism moves to the left and stops above the workbench 2. The manipulator 5 moves to the bottom under the drive of the cylinder 7. At this time, the manipulator 5 On the same plane as the workpiece 3 placed in the workpiece holder 13, the second conveyor belt 14 rotates under the drive of its driving device until the workpiece corresponding to the manipulator 5 stops when it needs to be processed, and the manipulator 5 stretches and grabs it. Take the workpiece, the manipulator 5 shrinks, then rotates the manipulator and fixes the workpiece on the workbench 2, the spindle 4 drives the tool to process the workpiece, the processing of the workpiece by the spindle belongs to the prior art, and will not be described in detail. After the processing is completed, it can be taken The manipulator of the lower workpiece can replace the workpiece for processing, or the spindle can change the tool for the next step of processing the workpiece, or even the spindle can change the tool and the manipulator can change the workpiece for other processing. This cycle improves the work efficiency, and the same type of workpiece is processed. Among them, the fixing effect of fixing the workpiece by grabbing the workpiece with the manipulator is the same, so that the deviation between the processed workpieces is smaller.

Example 2:

As shown in Figures 4 and 5, the difference between the machine tool provided by the present invention and Embodiment 1 is that the manipulator 5 is a non-retractable manipulator. Move a certain distance to the left and replace the workpiece when it is not above the worktable 2, that is, when the spindle 4 and the cylinder 7 move a certain distance to the left, the manipulator 5 moves down to the bottom under the drive of the cylinder 7, and the manipulator 5 Grab the workpiece, and then continue to move to the left to the top of the workbench 2. At this time, the manipulator 5 rotates and fixes the workpiece on the workbench 2, and then uses the tool to process the workpiece. In this setting, it is necessary to set the entire feeding mechanism in advance. The distance moved to the left, the length of the manipulator and the distance between the manipulator and the main shaft do not need to adopt a retractable manipulator, which reduces the cost and achieves the same technical effect. Of course, after the entire feeding mechanism moves to the left for a certain distance, the telescopic manipulator can be used to grab the workpiece, and then move to the top of the workbench to fix the workpiece for processing.
