Description

Technical Field

[0001] The utility model relates to the technical field of iron chip cutting, in particular to an iron chip cutting device for machine tool processing. Background Art

[0002] When the machining center processes the workpiece, the tool will generate a large amount of iron chips when cutting the workpiece. Generally, some of the iron chips will be broken off, but most of the iron chips will continue to form iron chip wires. These iron chip wires will swing with the rotation of the workpiece or the tool. Under the action of centrifugal force, the far end of the iron chip wire will be swung around the circumference of the processing position, especially in the case of long cutting path and deep drilling depth. The length of the iron chip wire will be significantly longer, and as the iron chip wire continues to grow longer, its swinging range will also increase. Since the iron chip wire generated by processing is relatively sharp, it is easy to scratch the surface of the workpiece when it is swung, and it may even scratch the equipment inside the machining center. There are also certain safety hazards. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model proposes a machine tool processing iron chip cutting device to solve the above problems.

[0006] A base, which is mounted on the workbench of the machine tool;

[0007] The adjustment mechanism comprises a vertical cylinder, an insertion column and a connecting column, wherein the bottom end of the vertical cylinder is mounted on the top of the base and the top end thereof faces upward, the insertion column is slidably inserted in the top end of the vertical cylinder, a first stud capable of abutting against the insertion column is threadedly screwed on the vertical cylinder, a sliding sleeve is transversely arranged on the top end of the insertion column, the connecting column is slidably inserted in the sliding sleeve, and a second stud capable of abutting against the connecting column is threadedly screwed on the sliding sleeve;

[0008] The cutting mechanism comprises a fixed bar and a movable bar, wherein the fixed bar is mounted on one end of the connecting column, the movable bar is parallel to the fixed bar and is slidably connected to one side of the fixed bar along its length direction, and the edges of the same side of the fixed bar and the movable bar are respectively linearly and evenly distributed with a plurality of cutting teeth, and the two rows of cutting teeth are closely attached to each other;

[0009] The driving mechanism is used to drive the movable bar to slide back and forth so that the two rows of cutting teeth are interlaced with each other.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] like Figure 1-2 As shown, the machine tool iron chip cutting device provided in this embodiment includes a base 1, an adjustment mechanism 2, a cutting mechanism 3 and a driving mechanism 4.

[0028] The base 1 is installed on the workbench of the machine tool. Specifically, the base 1 is located on both sides of the vertical cylinder 21 and is screwed with third studs 12. The bottom end of the third stud 12 is provided with an abutment plate 121. By rotating the third stud 12 upward, the abutment plate 121 can be pressed upward against the top wall of the slot of the workbench to fix the base 1.

[0029] The adjustment mechanism 2 includes a vertical cylinder 21, a plug column 22 and a connecting column 23. The bottom end of the vertical cylinder 21 is mounted on the top of the base 1 and its top end faces upward. The plug column 22 is slidably inserted at the top end of the vertical cylinder 21. A first stud 211 capable of abutting against the plug column 22 is threadedly screwed on the vertical cylinder 21. A sliding sleeve 221 is transversely arranged on the top end of the plug column 22. The connecting column 23 is slidably inserted in the sliding sleeve 221. A second stud 222 capable of abutting against the connecting column 23 is threadedly screwed on the sliding sleeve 221. In specific use, the height can be adjusted by sliding the plug column 22 up and down, the position of the plug column 22 can be fixed by tightening the first stud 211, the position of the end of the connecting column 23 can be changed by sliding the connecting column 23 transversely, and the position of the connecting column 23 can be fixed by tightening the second stud 222.

[0030] The cutting mechanism 3 includes a fixed bar 31 and a movable bar 32. The fixed bar 31 is installed at one end of the connecting column 23. The movable bar 32 is parallel to the fixed bar 31 and is slidably connected to one side of the fixed bar 31 along its length direction. The same side edges of the fixed bar 31 and the movable bar 32 are respectively linearly and evenly distributed with a plurality of cutting teeth 33. The two rows of cutting teeth 33 are tightly attached to each other. When the movable bar 32 slides, the cutting teeth 33 on the movable bar 32 will abut and interlace with the cutting teeth 33 on the fixed bar 31 to form a shear force.

[0031] The driving mechanism 4 is used to drive the movable bar 32 to slide back and forth so that the two rows of cutting teeth 33 are interlaced with each other.

[0032] Specifically, the driving mechanism 4 includes a mounting plate 41, a motor 42, a first rocker arm 43 and a second rocker arm 44. The mounting plate 41 is mounted on one end of the fixed bar 31, the first rocker arm 43 is rotatably connected to one end of the movable bar 32 close to the mounting plate 41, the motor 42 is mounted on the mounting plate 41, the second rocker arm 44 is mounted on one side of the output shaft of the motor 42 and is rotatably connected to the far end of the first rocker arm 43. When the output shaft of the motor 42 rotates, the second rocker arm 44 will be driven to rotate, and then the movable bar 32 will be repeatedly pushed and pulled by the first rocker arm 43, so as to realize the back and forth sliding of the movable bar 32.

[0033] Before processing the workpiece, the base 1 is first installed at the corresponding position of the workbench, and the position of the cutting mechanism 3 is adjusted by sliding the plug column 22 and the connecting column 23 so that the two rows of cutting teeth 33 can be directly opposite to the swinging path of the iron filings during processing, and then the driving mechanism 4 is started to drive the movable bar 32 to slide back and forth continuously, so that the two rows of cutting teeth 33 are staggered back and forth. When processing the workpiece, when there is an excessively long iron filing through the cutting mechanism 3, since the iron filings generated during processing are usually spirally curled, the iron filings will be stuck between adjacent cutting teeth 33. The movable bar 32 slides back and forth to cause the two rows of cutting teeth 33 to be staggered and sheared, and then the iron filings stuck on the cutting teeth 33 are cut off. Every time the iron filings rotate one circle, they can be stuck and cut by the cutting teeth 33, which is beneficial to prevent the iron filings from being too long and improves the safety of the processing operation.

[0034] Preferably, a plurality of fixed surfaces are evenly distributed on the outer circumference of the connecting column 23, and the inner surface of the sleeve 221 is adapted to each fixed surface. The connecting column 23 can be pulled out from the sleeve 221 and the direction of the connecting column 23 can be rotated, and then the rotated connecting column 23 can be reinserted into the sleeve 221, thereby changing the orientation of the cutting teeth 33, which is beneficial for adjusting the orientation of the cutting teeth 33 according to different workpiece processing methods.

[0035] Furthermore, a plurality of sockets 11 are evenly distributed around the vertical cylinder 21 on the base 1. The bottom end of the vertical cylinder 21 is rotatably connected to the top of the base 1 and a plug sleeve 212 is provided on one side of its bottom. A pin 213 is slidably inserted on the plug sleeve 212. The pin 213 can be movably inserted into any socket 11 to change the orientation of the cutting mechanism 3, thereby further improving the freedom of position adjustment of the cutting mechanism 3.
