DETAILED DESCRIPTION
[0027] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0028] like Figure 1-16As shown, the present invention provides a CNC machine tool capable of bidirectional synchronous processing and unidirectional switching, comprising a base 1, a support plate 32 is provided at the upper end of the base 1, a slide box 24 is provided at the front end of the support plate 32, a sleeve seat 4 is provided at the front end of the slide box 24, a plurality of clamping plates 18 are provided in the sleeve seat 4, a rotatable active spur gear 3 is also provided on the sleeve seat 4, and a structure in which the plurality of clamping plates 18 move synchronously inward when the active spur gear 3 rotates; a rotatable first threaded rod 27 is provided at the lower end of the slide box 24, and a structure in which the sleeve seat 4 flips and moves upward when the first threaded rod 27 rotates, a rotatable small pulley 35 is provided at the lower end of the support plate 32, and a first clamping component matched with the sleeve seat 4 is also provided at the upper end of the base 1, and a structure in which the sleeve seat 4 moves back and forth reciprocatingly and the first clamping component moves upward intermittently and progressively when the small pulley 35 rotates.
[0029] like Figure 1-2 As shown in , 8, 10, and 13, the base 1 supports and fixes the device; second clamping components are provided at both ends of the sleeve 4, and the first clamping component and the second clamping component are used to clamp the tool, and their structural principles are the same; by placing the part to be processed in the sleeve 4, when the active spur gear 3 rotates, the multiple clamping plates 18 can clamp and fix the outer surface of the part, and when the spur gear continues to rotate, it will drive the part to rotate, and then the cutter of the second clamping component moves, so that the outer surface of the part is processed and cut synchronously at both ends, realizing two-way processing. When it is necessary to switch the direction to cut the end face of the part, that is, to make a slotted hole on the end face of the shaft, by rotating the first threaded rod 27, the sleeve 4 will flip and move upward. The sleeve 4 flips, that is, flips 90 degrees, so that the end face of the part to be processed faces downward, and moves to the upper end of the first clamping component. Moving upward for a distance can prevent the part from colliding with the first clamping component; when the small pulley 35 rotates, the sleeve 4 can move back and forth and the first clamping component can move upward intermittently and progressively, thereby cutting the end face of the part.
[0030] A first motor 2 is fixedly connected to one side of the sleeve 4, a driving spur gear 3 is fixedly connected to the first motor 2, a driven spur gear 5 is meshed with the front end of the driving spur gear 3, a first chuck 6 is rotatably connected to the right inner wall of the sleeve 4, the driven spur gear 5 is fixedly connected to one side of the first chuck 6, a vortex rack 7 is fixedly connected to the other side of the first chuck 6, a second chuck 8 is rotatably connected to the middle part of the sleeve 4, four evenly distributed long sliders 10 are slidably connected to the inner wall of the second chuck 8, the right end surfaces of the long sliders 10 are respectively fixedly connected to first sliding pins 11 meshing with the vortex rack 7, a fixed plate 9 is fixedly connected to the inner wall of the left end of the sleeve 4, a second sliding pin 14 is respectively provided on the inner wall of the left end of the long slider 10, and four sections of evenly distributed key-shaped sliding grooves meshing with the corresponding second sliding pins 14 are opened on the inner wall of the fixed plate 9; the clamping plates 18 are respectively installed on the inner ends of the corresponding long sliders 10.
[0031] like Figure 3-7As shown, the function of the first motor 2 is to provide a rotational force for the active spur gear 3, and the long slider 10 can slide inward or outward on the inner wall of the second chuck 8, as shown in FIG. Figure 6 As shown, the first sliding pin 11 is engaged in the spiral rack 7 as shown in FIG. Figure 5 As shown, through holes are respectively provided in the middle of the sleeve 4, the fixed plate 9, the first chuck 6 and the second chuck 8, so that parts can be inserted into the through holes. When the parts need to be fixed, the parts are inserted into the through holes and the first motor 2 is started, which will cause the active spur gear 3 to rotate. The active spur gear 3 rotates through the engagement with the driven spur gear 5, which will drive the driven spur gear 5, the first chuck 6 and the spiral rack 7 to rotate synchronously. Since the second sliding pin 14 is engaged with the key-shaped slide groove, the second sliding pin 14 will limit the corresponding long slider 10 to move synchronously inward or outward when it is engaged with the key-shaped slide groove. When the spiral rack 7 rotates, the first sliding pin 11, the long slider 10, the second sliding pin 14 and the clamping plate 18 will move synchronously inward or outward through the engagement with the first sliding pin 11. When the clamping plate 18 moves inward, the parts will be clamped and fixed.
[0032] The inner walls of the long sliders 10 are slidably connected with wedge blocks 12, and the second sliding pins 14 are slidably connected to the corresponding inner walls of the long sliders 10. The inner walls of the left ends of the long sliders 10 are respectively provided with first springs 15 that match the corresponding second sliding pins 14, and the right ends of the second sliding pins 14 are respectively fixedly connected with third sliding pins 13. The wedge blocks 12 are respectively provided with V-shaped grooves that match the corresponding third sliding pins 13. The inner ends of the wedge blocks 12 are respectively fixedly connected with inner sliding rods 17, and the inner ends of the inner sliding rods 17 respectively penetrate the corresponding inner end faces of the long sliders 10 and are slidably connected to the inner walls of the long sliders 10. The outer surfaces of the inner sliding rods 17 are respectively covered with tension springs 16 that match the wedge blocks 12. The clamps 18 are respectively fixedly connected to the corresponding inner end faces of the inner sliders. The outer end faces of the wedge blocks 12 are respectively fixedly connected with reset rods 19, and the outer end faces of the reset rods 19 are respectively fixedly connected with reset pads 20.
[0033] like Figure 6-7 As shown, the left end of the long slider 10 extends backward and is provided with an extension slot. The long slider 10, the second slide pin 14, the third slide pin 13, and the wedge block 12 are installed and shaped as shown in FIG. Figure 7 As shown, the outer surface of the second sliding pin 14 is fixed with a circular pad, which is slidably connected to the inner wall of the extension groove, limiting the second sliding pin 14 to slide left and right, and the first spring 15 has a leftward thrust on the circular gasket, so that the second sliding pin 14 has a leftward driving force, so that the second sliding pin 14 is engaged with the key-shaped sliding groove; the wedge block 12 can slide inward or outward on the inner wall of the corresponding long slider 10; the inner slide rod 17, the clamping plate 18, the tension spring 16, the reset rod 19, and the reset pad 20 are installed and shaped as shown in FIG. Figure 7As shown, the inner slide bar 17, the reset rod 19, and the clamping plate 18 can slide synchronously inward or outward respectively; one end of the tension spring 16 is fixedly connected to the inner end face of the long slider 10, and the other end of the tension spring 16 is fixedly connected to the corresponding wedge block 12, and the tension spring 16 acts on the wedge block 12 to have an inward driving force; when the volute rack 7 rotates, it will drive the corresponding clamping plate 18, the first sliding pin 11, the second sliding pin 14, the wedge block 12, the third sliding pin 13, etc. to move synchronously inward. When the clamping plate 18 contacts the outer surface of the part, it will no longer move inward. At this time, the volute rack 7 continues to rotate, which will cause the first sliding pin 11, the long slider 10, the second sliding pin 14, the third The sliding pin 13 and the first spring 15 continue to move inward synchronously. Since the clamping plate 18 moves inwardly to contact the outer surface of the part and cannot continue to move inwardly, the corresponding inner sliding rod 17, wedge block 12, reset rod 19, reset pad 20, etc. no longer move inwardly. At this time, when the long slider 10, etc. continue to move inwardly, the tension spring 16 will be pulled inwardly to extend, and the corresponding clamping plate 18 will have an inward extrusion force under the tension of the tension spring 16, so that the part is fixed in the sleeve 4. When the spiral rack 7 continues to rotate, the corresponding long slider 10, the first sliding pin 11, the second sliding pin 14, the third sliding pin 13, etc. will move inward synchronously. When the third sliding pin 13 moves to the right, the third sliding pin 13 will move to the right under the meshing of the third sliding pin 13 and the V-shaped groove. The third sliding pin 13 moving to the right will drive the corresponding second sliding pin 14 and the annular pad to move to the right. When the annular pad moves to the right, it will compress the first spring 15. When the second sliding pin 14 moves to the right, it will slowly enter the long slider 10. When the second sliding pin 14 completely enters the long slider 10, it will disengage from the corresponding key-shaped slot. After the second sliding pin 14 disengages from the key-shaped slot, the fixed disk 9 no longer limits the corresponding second sliding pin 14, the long slider 10, etc., and at this time, the clamping plate 18 is in a state of being pressed inward. State, clamping the outer surface of the part, at this time, the second sliding pin 14, the long slider 10, and the clamping plate 18 will drive the corresponding long slider 10, the first sliding pin 11, the second sliding pin 14, the clamping plate 18, etc. to rotate synchronously in a circular manner under the meshing of the first sliding pin 11 and the spiral rack 7. When the clamping plate 18 rotates in a circular manner, it will drive the part to rotate, so that the part follows the active spur gear 3 to rotate, and the two ends of the outer surface of the part are cut. Therefore, by starting the first motor 2, the clamping plate 18 will first clamp and fix the part, and after clamping and fixing, the clamping plate 18 drives the part to rotate in a circular manner, so that the part rotates and cuts chips, thereby improving the clamping and fixing efficiency, and can perform synchronous chip cutting in both directions;When the processing is completed and the parts need to be disassembled, the first motor 2 can be started to reverse. When the first motor 2 reverses, the active spur gear 3, the vortex rack 7, etc. will be driven to reverse synchronously. The reversal of the vortex rack 7 will drive the first sliding pin 11, the long slider 10, the clamping plate 18, the second sliding pin 14, the third sliding pin 13, the wedge block 12, etc. to reverse synchronously in a circular manner. When the second sliding pin 14 reverses in a circular manner to meet the key-shaped slide groove at the upper end of the corresponding fixed disk 9, the second sliding pin 14 will enter the inner wall of the key-shaped slide groove again under the self-spring of the first spring 15 and the tension spring 16. When the second sliding pin 14 enters the key-shaped slide groove When the inner wall is reached, the corresponding long slider 10, first sliding pin 11, wedge block 12, clamping plate 18, etc. will be limited again, and they will no longer rotate synchronously with the spiral rack 7, but can only move synchronously inward or outward. When the spiral rack 7 continues to rotate, it will engage the first sliding pin 11, long slider 10, second sliding pin 14, clamping plate 18 and move synchronously outward. When the chuck moves outward, it will break away from the contact with the outer surface of the part, that is, it will no longer clamp the outer surface of the part. When the long slider 10, etc. moves outward to make the reset pad 20 contact with the inner wall of the second chuck 8, the device is reset. Its working principle is the same and will not be repeated. ;
[0034] The inner wall of the slide box 24 is slidably connected with a connecting column 21, and the sleeve 4 is fixedly connected to the front end surface of the connecting column 21. The front end surface of the slide box 24 is slidably connected with a first slide plate 25, and the upper end of the first slide plate 25 is fixedly connected to a second motor 26. The first threaded rod 27 is fixedly connected to the second motor 26. The outer surface of the first threaded rod 27 is threadedly connected with a threaded slider 28 slidably connected to the first slide plate 25, and a long sliding pin 29 is fixedly connected to the threaded slider 28. A swing arm 30 is provided at the front end of the outer surface of the connecting column 21, and a key-shaped sliding groove matching the long sliding pin 29 is provided on the inner wall of the swing arm 30; the rear end of the outer surface of the connecting column 21 is fixedly connected to the first spur gear 22, and the inner wall of the slide box 24 is fixedly connected to a spur rack 23 meshing with the first spur gear 22. The rear end of the slide box 24 is rotatably connected with a third threaded rod 73, and the third threaded rod 73 is threadedly connected to the inner wall of the support plate 32.
[0035] like Figure 8-10 As shown, an anti-drop pad is fixedly connected to the middle of the outer surface of the connecting column 21, and the sliding box 24, the connecting column 21, the first straight gear 22, and the straight rack 23 are installed and shaped as shown in FIG. Fig. 9 As shown, the anti-drop pad can limit the connection column 21 to move up and down on the inner wall of the slide box 24 without affecting the rotation of the connection column 21; the connection column 21, the swing arm 30, the long sliding pin 29, the threaded slider 28, the first slide plate 25, and the first threaded rod 27 are installed and shaped as shown in FIG. Figure 7As shown, the first slide plate 25 is connected to the front end surface of the slide box 24 by sliding up and down, and the left and right ends of the outer surface of the first threaded rod 27 are respectively fixed with bearing seats, and the bottom ends of the bearing seats are respectively fixed to the upper end surface of the first slide plate 25, so that the first threaded rod 27 can only rotate, and the threaded slider 28 is connected to the upper end of the first slide plate 25 by sliding left and right; when the second motor 26 is started, the corresponding first threaded rod 27 will rotate, and the rotation of the first threaded rod 27 will cause the threaded slider 28 to move left or right through the threaded connection. When the long sliding pin 29 moves to the right, it will drive the corresponding long sliding pin 29 to move to the right. When the long sliding pin 29 moves to the right, it will drive the swing arm 30 to swing to the left through the meshing with the key-shaped slide groove. When the swing arm 30 swings to the left, it will drive the connecting column 21 to rotate. When the connecting column 21 rotates, it will drive the corresponding first spur gear 22 to rotate. When the first spur gear 22 rotates, it will mesh with the spur rack 23, which will make the connecting column 21 and the sleeve 4 move upward and rotate synchronously, so that the sleeve 4 will turn over and rotate, preventing the parts in the sleeve 4 from colliding with the tool. When the connecting column 21 moves upward, it will drive the corresponding swing arm 30, the first threaded rod 27, the first slide plate 25, etc. to move upward synchronously, so that the device can maintain normal operation. When the threaded slider 28 moves to the right, the connecting column 21 will move downward while flipping and resetting. The principle is the same and will not be repeated here. The sliding box 24 is connected to the front end surface of the support plate 32. The upper and lower ends of the outer surface of the third threaded rod 73 are respectively fixed with bearing seats. The bearing seats are fixedly connected to the lower end surface of the slide box 24. The third threaded rod 73 can only rotate. The upper end of the outer surface of the third threaded rod 73 is fixed with a first crank 74. The function of the first crank 74 is to facilitate the rotation of the third threaded rod 73. The rotation function of the third threaded rod 73 is to facilitate the adjustment of the upper and lower positions of the slide box 24, and then adjust the height position of the part to be processed after flipping, so that the end face of the part to be processed corresponds to the tool. By rotating the third threaded rod 73, the third threaded rod 73, the slide box 24, and the part to be processed can be moved up or down under the threaded connection between the third threaded rod 73 and the support plate 32.
[0036] The left and right ends of the rear side of the upper end surface of the base 1 are respectively fixed with side plates 31, and a support plate 32 is slidably connected to the upper end surfaces of the two side plates 31. A third motor 34 is also fixedly connected to the middle part of the upper end surface of the base 1, and a small pulley 35 is fixedly connected to the third motor 34. A large pulley 36 is connected to the rear side of the upper end of the small pulley 35, and an I-shaped slide plate 37 is hinged at the non-center part of the front end surface of the large pulley 36. A swing rod 33 is hinged at the lower end of the inner end surface of the two side plates 31, and a rectangular slide groove matching the I-shaped slide plate 37 is opened in the middle of the swing rod 33. A first live pin 38 is provided at the lower end of the support plate 32, and a fork groove matching the first live pin 38 is provided at the upper end of the swing rod 33.
[0037] like Figure 10-11As shown, the support plate 32 is connected to the two side plates 31 in a sliding manner; the third motor 34 provides a rotational force for the small pulley 35, and the swing rod 33, the large pulley 36, the I-shaped slide plate 37, and the first movable pin 38 are installed and shaped as shown in FIG. Fig.11 As shown, the left and right ends of the outer surface of the first movable pin 38 are respectively fixed with fixed seats 44, and the fixed seats 44 are fixed to the lower end surface of the support plate 32, and the limited first movable pin 38 moves synchronously with the support plate 32; the large pulley 36 is rotatably connected to the corresponding inner wall of the side plate 31; when the second motor 26 is started, the corresponding small pulley 35 will be rotated, and the rotation of the small pulley 35 will drive the large pulley 36 to rotate, and when the large pulley 36 rotates, it will drive the I-shaped slide plate 37 to swing in a circle, and when the I-shaped slide plate 37 swings in a circle, it will drive the corresponding swing rod 33 to swing through the engagement with the rectangular slide groove, and the swing rod 33 has a quick return characteristic when swinging. When the swing rod 33 swings forward, the engagement of the I-shaped slide plate 37 with the rectangular slide groove will make the swing rod 33 swing slowly forward, and when the swing rod 33 swings backward, it will swing in the I-shaped slide plate 37. When the slide plate 37 is engaged with the rectangular slide groove, the swing rod 33 will swing backward quickly, so that the swing rod 33 has a quick return characteristic. When the swing rod 33 swings forward, the engagement of the fork groove and the first live pin 38 will make the first live pin 38 move forward. The forward movement of the first live pin 38 will drive the corresponding support plate 32, the sleeve 4, etc. to move forward synchronously. When the sleeve 4 moves forward, it will drive the parts forward. When the parts move forward, they come into contact with the tool, thereby cutting the end faces of the parts; when the swing rod 33 swings backward, it will drive the corresponding support plates 32, parts, etc. to swing backward. Since the swing rod 33 swings backward quickly, the corresponding support plates 32 and parts also move backward quickly.

[0039] like Figure 10-14 As shown, the first disc 39 and the inner wall of the large pulley 36 are fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the side plate 31; Fig.12 As shown, one end face of the small threaded rod 41 is fixedly connected to a first handle 40, and the function of the first handle 40 is to facilitate the rotation of the small threaded rod 41, and the small threaded rod 41 can be slidably connected to the inner wall of the first disc 39 up and down; the long connecting rod 43 is installed and shaped as Fig.10 As shown, the rocker 48, the ratchet 52, and the ratchet teeth 49 are installed and shaped as shown in FIG. Fig.13 As shown, the outer surface of the connecting shaft 76 is rotatably connected with a bearing seat, and the bottom end of the bearing seat is fixedly connected to the upper end surface of the fixing seat 44. The corresponding rocker 48 is sleeved on the connecting shaft 76 and rotatably connected to the bearing seat, so that the rocker 48 can swing back and forth on the outer surface of the connecting shaft 76; through the limit of the guide rod 46, the first clamping part can only move up and down, and the lead screw 56 can only move up and down with the first clamping part; Fig.10A second crank handle 75 is fixedly connected to one end surface of the connecting shaft 76 shown in the figure, and the function of the second crank handle 75 is to facilitate the driving of the connecting shaft 76 to rotate; a reset handle 50 is fixedly connected to one end surface of the ratchet 49, and the function of the reset handle 50 is to facilitate the driving of the ratchet 49 to move upward and disengage from the ratchet wheel 52; a stopper is fixedly connected to the left end surface of the rocker 48, and the other end of the third spring 51 is fixedly connected to the stopper, and the ratchet 49 is meshed with the ratchet wheel 52 through the elastic force of the third spring 51; when the large pulley 36 rotates, it will drive the first disk 39 to rotate, and the rotation of the first disk 39 will drive one end of the long connecting rod 43 to rotate in a circle, and the other end of the long connecting rod 43 will pull the rocker 48 to swing back and forth, and when the rocker 48 swings forward, When the rocker 48 swings backward, it drives the ratchet 49 to swing backward in a circle. Since the ratchet 49 and the ratchet 52 are in one-way meshing, the ratchet 52 can rotate. The rotation of the ratchet 52 can drive the connecting shaft 76 to rotate. The rotation of the connecting shaft 76 can drive the first bevel gear 53, the second bevel gear 54 and the nut 55 to rotate synchronously. When the nut 55 rotates, it can drive the lead screw 56 and the first clamping component to move upward synchronously through the threaded connection with the lead screw 56. When the first clamping component moves upward, it can drive the corresponding tool to move upward, so that the tool can move upward aggressively to cut the end face of the part. When the rocker 48 swings backward, it can drive the ratchet 49 to swing backward in a circle. Since the ratchet 49 and the ratchet 52 are in one-way meshing, The ratchet 49 will compress the third spring 51 when the ratchet wheel 52 is engaged, and the ratchet wheel 52 will be reciprocated up and down, that is, it will no longer drive the ratchet wheel 52 to rotate. Therefore, the first clamping component and the tool will intermittently and slowly move upward through the engagement of the ratchet 49 and the ratchet wheel 52. Under the cooperation of the first disc 39 and the large pulley 36, the corresponding part will move slowly forward and meet the tool for cutting, that is, the corresponding tool will slowly move upward. When the part moves back quickly, the tool is in an intermittent stop state, which can not only improve the cutting efficiency, but also prevent the tool from excessive wear and reducing its service life. Due to the different materials of the parts to be processed, such as different carbon contents of alloys, the hardness will also be different during cutting. Therefore, by rotating the first handle 40, the adjustable The size of the displacement of the intermittent upward attack of the tool is adjusted, so as to adjust the thickness of the chips cut by the tool each time according to the material of the part. The small threaded rod 41 is rotated by rotating the first handle 40. The rotation of the small threaded rod 41 through the threaded connection with the small slider 42 will cause the small slider 42 to move inward or outward. When the small slider 42 moves inward, it will drive the rear end of the corresponding long connecting rod 43 to move inward. At this time, when the first disc 39 rotates, it will drive the small slider 42 to make a small radius circumferential rotation. At this time, one end of the corresponding long connecting rod 43 follows the small slider 42 to make a small radius circumferential rotation, and the other end of the long connecting rod 43 drives the corresponding rocker 48 to swing back and forth slightly, so that the lead screw 56 will rotate intermittently by a small amplitude each time;Thus, the impact displacement of the tool becomes smaller and the cutting amount is reduced. When the hardness of the part to be processed is small, the impact displacement of the tool can be increased by reversing the first handle 40, thereby accelerating the cutting rate. The principle is the same and will not be repeated. When it is necessary to reset the lead screw 56, the first clamping member, and the tool, the reset handle 50 is pulled upward to disengage the ratchet 49 from the ratchet wheel 52, and then the reset can be achieved by rotating the second crank handle 75. No further description will be given. ;

When the second movable pins 62 move synchronously inward, they will drive the corresponding square slider 61 and clamp block 63 to move synchronously inward, so that the clamp block 63 clamps the tool and fixes it, and the worm wheel 59 and worm 58 have a self-locking function; when the second movable pin 62 moves outward, the clamp block 63 will spread outward, loosening the tool and no longer clamping it, making it convenient to replace a new tool.

The second clamping component has the same structure and working principle as the first clamping component, and will not be repeated here. When the front and rear coordinate positions of the second clamping component need to be adjusted, the second threaded rod 66 will be rotated by starting the fourth motor 65. The rotation of the second threaded rod 66 will cause the support cross frame 64 to move inward or outward synchronously through the threaded connection with the connecting plate 67. When the left and right coordinate positions of the second clamping component need to be adjusted, the first steering bevel gear 69, the second steering bevel gear 70, and the two-way threaded rod 71 will be rotated synchronously by starting the fifth motor 68.
