Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: a fixing device for machine tool processing, including a platform 1, a fixed table 2 is arranged on the upper surface of the platform 1, a rotating component 3 is arranged inside the platform 1, and a moving component 4 is arranged inside the platform 1;

[0030] The rotating assembly 3 includes a driving rod 32 and a partition 35. The outer wall of the driving rod 32 is rotatably connected to the inner wall of the housing cavity of the platform 1. The side wall of the partition 35 is fixedly connected to the inner side wall of the platform 1. One end of the driving rod 32 is fixedly installed with a turning handle 31. The other end of the driving rod 32 extends into the interior of the platform 1. A rotating rod 34 is rotatably installed on the inner side wall of the platform 1. A worm is provided on the outer wall of the rotating rod 34. One end of the rotating rod 34 is provided with a groove, and a first ratchet gear 310 is fixedly installed on the inner wall of the groove. A first bevel gear 33 is fixedly installed on the outer wall of the driving rod 32. The other end of the driving rod 32 is rotatably connected to the inner wall of the groove of the rotating rod 34. A first locking tooth 311 is rotatably installed at the other end of the driving rod 32 through a short shaft. A first support frame 313 is fixedly installed at the other end of the driving rod 32. A first fixing frame 312 is fixedly installed on the lower surface of the first locking tooth 311. A first connecting spring 314 is provided on the outer surface of the first fixing frame 312. One end of the first connecting spring 314 is fixedly connected to the outer surface of the first support frame 313. The first locking tooth 311 is adapted to the first ratchet gear 310. A cross rod 37 is rotatably installed on the inner bottom wall of the platform 1. A worm gear 36 is fixedly installed on the outer wall of the cross rod 37. The worm gear 36 is meshed with the worm on the rotating rod 34. One end of the cross rod 37 extends outside the upper surface of the partition 35. A rotating sleeve 38 is slidably installed on the outer wall of the cross rod 37. A fixing ring 39 is fixedly installed on the outer wall of the rotating sleeve 38. One end of the rotating sleeve 38 extends outside the upper surface of the platform 1 and is fixedly connected to the lower surface of the fixing table 2.

[0031] The specific implementation method is as follows: When a part is fixed on the fixing table 2 and the angle of the part needs to be adjusted, turn the turning handle 31 clockwise. The turning handle 31 drives the driving rod 32 to rotate. The driving rod 32 drives the first bevel gear 33 to rotate. The first bevel gear 33 drives the second bevel gear 41 to rotate. The second bevel gear 41 drives the driving column 43 on the fixing plate 42 to rotate. Since the tooth direction of the second locking tooth 48 installed on the driving column 43 is opposite to that of the teeth on the second ratchet gear 47 of the reciprocating lead screw 45 at this time, the driving column 43 will not drive the reciprocating lead screw 45 to rotate while rotating. At the same time, the first locking tooth 311 installed on the driving rod 32 is pressed against the teeth of the first ratchet gear 310 under the action of the first connecting spring 314 on the first support frame 313 and the first fixing frame 312. Therefore, it will drive the first ratchet gear 310 to rotate. The first ratchet gear 310 drives the rotating rod 34 to rotate. The rotating rod 34 drives the worm gear 36 to rotate through the worm. The worm gear 36 drives the cross rod 37 to rotate. The cross rod 37 drives the rotating sleeve 38 to rotate. The rotating sleeve 38 drives the fixing ring 39 to rotate on the connecting rod 46. The rotating sleeve 38 drives the fixing table 2 to rotate, so as to adjust the angle of the part on the fixing table 2 for processing.

[0032] The moving component 4 includes a fixing plate 42 and a reciprocating lead screw 45. One end of the fixing plate 42 is fixedly connected to the inner side wall of the platform 1. One end of the reciprocating lead screw 45 is rotatably connected to the inner wall of the top surface of the platform 1. A driving column 43 is rotatably installed on the inner wall of the fixing plate 42. One end of the driving column 43 is fixedly installed with a second bevel gear 41. The first bevel gear 33 is meshed with the second bevel gear 41. The other end of the driving column 43 extends outside the upper surface of the partition plate 35. The other end of the reciprocating lead screw 45 is provided with a groove. A second ratchet gear 47 is fixedly installed on the inner wall of the groove. The other end of the driving column 43 is rotatably connected to the inner wall of the groove of the reciprocating lead screw 45. A second pawl 48 is rotatably installed at the other end of the driving column 43 through a short shaft. A second fixing frame 49 is fixedly installed on the side wall of the second pawl 48. A second support frame 410 is fixedly installed at the other end of the driving column 43. A second connecting spring 411 is arranged on the outer surface of the second fixing frame 49. One end of the second connecting spring 411 is fixedly connected to the outer surface of the second support frame 410. The second pawl 48 is adapted to the second ratchet gear 47. A threaded sleeve 44 is threadedly installed on the outer surface of the reciprocating lead screw 45. A connecting rod 46 is fixedly installed on the side wall of the threaded sleeve 44. One end of the connecting rod 46 is slidably connected to the inner side wall of the fixing ring 39.

[0033] The specific implementation method is as follows: At the same time, when it is necessary to adjust the height of the part, rotate the handle 31 counterclockwise. The handle 31 drives the driving rod 32 to rotate. Since the tooth direction of the first pawl 311 installed on the driving rod 32 is opposite to that of the teeth on the first ratchet gear 310 at this time, the driving rod 32 will not drive the rotating rod 34 to rotate while rotating. At the same time, the driving rod 32 drives the second bevel gear 41 to rotate through the first bevel gear 33. Similarly, the second bevel gear 41 drives the driving column 43 on the fixing plate 42 to rotate. At this time, the second pawl 48 installed on the driving column 43 abuts against the teeth of the second ratchet gear 47 under the action of the second support frame 410 and the second connecting spring 411 on the second fixing frame 49. Therefore, the second pawl 48 will drive the second ratchet gear 47 to rotate, and then the reciprocating lead screw 45 rotates. The reciprocating lead screw 45 drives the threaded sleeve 44 to move through the thread. The threaded sleeve 44 drives the rotating sleeve 38 to move through the connecting rod 46. The rotating sleeve 38 drives the fixed table 2 to move, so as to adjust the height of the part on the fixed table 2.

[0034] Working principle: After fixing the part on the fixed table 2 and when the angle of the part needs to be adjusted, turn the handle 31 clockwise. The handle 31 drives the driving rod 32 to rotate. The driving rod 32 drives the first bevel gear 33 to rotate. The first bevel gear 33 drives the second bevel gear 41 to rotate. The second bevel gear 41 drives the driving column 43 on the fixing plate 42 to rotate. Since the tooth direction of the second engaging tooth 48 installed on the driving column 43 is opposite to that of the tooth of the second ratchet gear 47 on the reciprocating lead screw 45 at this time, the driving column 43 will not drive the reciprocating lead screw 45 to rotate while rotating. At the same time, the first engaging tooth 311 installed on the driving rod 32 abuts against the tooth of the first ratchet gear 310 under the action of the first connecting spring 314 on the first support frame 313 and the first fixing frame 312. Therefore, it will drive the first ratchet gear 310 to rotate. The first ratchet gear 310 drives the rotating rod 34 to rotate. The rotating rod 34 drives the worm gear 36 to rotate through the worm. The worm gear 36 drives the cross rod 37 to rotate. The cross rod 37 drives the rotating sleeve 38 to rotate. The rotating sleeve 38 drives the fixing ring 39 to rotate on the connecting rod 46. The rotating sleeve 38 drives the fixed table 2 to rotate, so as to adjust the angle of the part on the fixed table 2 for processing. At the same time, when the height of the part needs to be adjusted, turn the handle 31 counterclockwise. The handle 31 drives the driving rod 32 to rotate. Since the tooth direction of the first engaging tooth 311 installed on the driving rod 32 is opposite to that of the tooth of the first ratchet gear 310 at this time, the driving rod 32 will not drive the rotating rod 34 to rotate while rotating. At the same time, the driving rod 32 drives the second bevel gear 41 to rotate through the first bevel gear 33. Similarly, the second bevel gear 41 drives the driving column 43 on the fixing plate 42 to rotate. At this time, the second engaging tooth 48 installed on the driving column 43 abuts against the tooth of the second ratchet gear 47 under the action of the second connecting spring 411 on the second support frame 410 and the second fixing frame 49. Therefore, the second engaging tooth 48 will drive the second ratchet gear 47 to rotate, and then the reciprocating lead screw 45 rotates. The reciprocating lead screw 45 drives the threaded sleeve 44 to move through the thread. The threaded sleeve 44 drives the rotating sleeve 38 to move through the connecting rod 46. The rotating sleeve 38 drives the fixed table 2 to move, so as to adjust the height of the part on the fixed table 2.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
