Technical Field
[0001] The utility model relates to the technical field of milling and drilling machines, in particular to a milling and drilling machine with stable clamping. Background Technique
[0002] The milling and drilling machine is one of the main equipment for machining. The method of using a milling cutter to process a workpiece on the milling and drilling machine is called milling. It can be used to process planes, steps, inclined planes, grooves, formed surfaces, gears, and cutting.
[0003] Most of the existing fixtures of milling and drilling machines are driven by two cylinders. However, there will be a time difference when the two cylinders start, resulting in asynchronous start of the two cylinders, thus leading to unstable clamping. At the same time, debris will be generated when cutting the workpiece, and the debris cannot be collected, resulting in it remaining above the workbench. Summary of the Utility Model

A fixing plate is fixedly installed on the top of the box body. A moving module is fixedly assembled on the top of the fixing plate. A fixing column is fixedly installed on the top of the fixing plate. A cutting module is fixedly installed on the outer wall of the top of the fixing column. A cutter head is fixedly assembled at the bottom of the cutting module. A collection drawer is slidably connected to the inner wall of the box body. One end of a vacuum pump and a dust collection pipe are respectively fixedly installed on the outer wall of the box body. The other end of the dust collection pipe is provided with a dust collection head assembly. A fixing block is fixedly installed on the top of the moving module. A cylinder is fixedly installed on the outer wall of the fixing block. A pushing block is fixedly installed at the telescopic end of the cylinder. A rack is fixedly installed on the outer wall of the pushing block. A gear is rotatably connected to the bottom of the inner wall of the fixing block. A clamping block is fixedly installed on the top of the pushing block.
[0006] As a preferred technical solution of the utility model, the dust collection head assembly includes a connecting handle. A fixing head is fixedly installed on the top of the connecting handle. A servo motor is fixedly installed on the outer wall of the fixing head. A belt is fixedly installed on the power output shaft of the servo motor.

[0007] As a preferred technical solution of the utility model, the number of the cleaning blocks is several, and several cleaning blocks are circumferentially arranged on the outer wall of the rotating shaft.
[0008] As a preferred technical solution of the utility model, a protruding column is arranged at one end of the rotating shaft close to the belt, and the protruding column is fixedly sleeved with the belt.
[0009] As a preferred technical solution of the present utility model, the rack and the gear are on the same horizontal line and the rack meshes with the gear.
[0010] As a preferred technical solution of the present utility model, the number of the air cylinders, the pushing blocks, the racks and the clamping blocks is two, and the two air cylinders, the pushing blocks, the racks and the clamping blocks are diagonally distributed on the inner wall of the fixed block.
[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] 1. For the milling and drilling machine with stable clamping, by starting the air cylinder, the air cylinder drives the pushing block to move. When the pushing block drives the rack to move, the rack drives the gear to rotate. The gear drives another rack to move, and the other rack drives another pushing block to move, so that the two clamping blocks move towards the middle of the fixed block at the same time, eliminating the starting time difference of the two air cylinders, thus making the clamping more stable.
[0013] 2. For the milling and drilling machine with stable clamping, by starting the vacuum pump, the vacuum pump evacuates the inside of the box body, making the inside of the box body form a negative pressure with the outside world, so that the dust collecting pipe generates suction, and then the connecting handle generates suction. While the connecting handle generates suction, the fixed head generates suction. By starting the servo motor, the servo motor drives the rotating shaft to rotate through the belt, so that several cleaning blocks rotate. Place the fixed head above the fixed block, and the cleaning blocks sweep up the debris. Through the suction generated by the connecting handle, the debris is absorbed into the inside of the box body. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating shaft 1004 is rotatably connected to the inner wall of the fixed head 1002. A cleaning block 1006 is fixedly installed on the outer wall of the rotating shaft 1004. In the above structure, by starting the servo motor 1003, the servo motor 1003 drives the belt 1005 to rotate, the belt 1005 drives the rotating shaft 1004 to rotate, the rotating shaft 1004 drives the cleaning block 1006 to rotate, and the dust located at the bottom of the cleaning block 1006 is swept up by the rotation of the cleaning block 1006, and the dust is absorbed by the suction force generated by the connecting handle 1001.
[0024] In a preferred embodiment, the number of cleaning blocks 1006 is several, and several cleaning blocks 1006 are circumferentially arrayed on the outer wall of the rotating shaft 1004.

[0028] Working principle: Place the raw material above the fixed block 15, start the two cylinders 11, so that the cylinders 11 drive the pushing blocks 12 to move. The pushing blocks 12 drive the racks 13 to move. When the racks 13 move, they drive the gears 14 to rotate. The gears 14 drive the other racks 13 to move.

At this time, start the moving module 3 and the cutting module 5 to cut the raw material. When the raw material cutting is completed, remove the raw material. At this time, the staff holds the connecting handle 1001 and starts the vacuum pump 7 and the servo motor 1003 at the same time. The vacuum pump 7 extracts air from the inside of the box body 1, so that a vacuum is formed inside the box body 1 and a negative pressure is formed with the outside world, causing the dust collecting pipe 9 to generate suction, so that the connecting handle 1001 generates suction.
