[0029] A first threaded rod 5 placed coaxially is provided just above the turntable 4. Both ends of the first threaded rod 5 pass through the support plate 2 and are rotatably connected to the support plate 2. A first slider 6 connected by threaded engagement is provided on the first threaded rod 5. The upper end surface of the first slider 6 fits with the lower end surface of the connecting plate 1. A first telescopic column 7 placed vertically downward is fixed to the lower end surface of the first slider 6. A connecting block is fixed to the lower end of the first telescopic column 7. A spring 8 is fixed between the first slider 6 and the connecting block. The spring 8 is sleeved on the first telescopic column 7. The spring 8 is always in a compressed state. The lower end surface of the first slider 6 is fixed to the first turntable. The motor 9 is driven, and the output end of the first rotating motor 9 is provided with a second threaded rod 10 placed vertically downward. The second threaded rod 10 is provided with a coaxially placed rotating sleeve 11. The rotating sleeve 11 is meshed with the second threaded rod 10. A coaxially placed rotating groove is opened on the side wall of the rotating sleeve 11. A first connecting member 12 for rotational connection is sleeved on the rotating groove. A first telescopic cylinder 13 is fixed to the lower end surface of the first connecting member 12. The first telescopic cylinder 13 is located on the side of the rotating sleeve 11 away from the first telescopic column 7. A groove cutter 14 is fixed to the lower end of the telescopic rod of the first telescopic cylinder 13;

[0030] A plurality of evenly distributed slots 111 are provided on the sidewalls of the rotating sleeve 11. A second telescopic column 15 placed vertically downward is fixed to the first slider 6. The second telescopic column 15 is located between the first rotating motor 9 and the first telescopic column 7. A second connecting member 16 is fixed to the connecting block. The other end of the second connecting member 16 is fixed to the side of the lower end wall of the second telescopic column 15 close to the first telescopic column 7. The second telescopic column 15 passes through any of the slots 111 and is in press contact with the wall of the slot 111. The second telescopic column 15 can slide along the slot 111. When the second telescopic column 15 is just separated from the slot 111, the lower end of the groove cutter 14 is flush with the lower end surface of the connecting block.

[0031] The roller drum on which the rope groove needs to be processed is placed between the two turntables 4 and clamped by the centering clamping assembly. At the same time, the connecting block is squeezed and contacted with the peripheral wall of the upper end of the roller drum. The connecting block drives the spring 8 and the first telescopic column 7 to perform telescopic adjustment, so that the connecting block can be adjusted according to the position of the roller drum with different diameters. The connecting block drives the second connecting piece 16, and the second connecting piece 16 drives the second telescopic column 15 to perform telescopic adjustment. The length of the section of the second telescopic column 15 passing through the slot 111 is adjusted according to the diameter of the roller drum. At the same time, the first rotating motor 9 is turned on, and the output end of the first rotating motor 9 drives the second threaded rod 10, and the second threaded rod 10 drives the rotating sleeve 11. Since the second telescopic column 15 passes through the slot 111 to limit the rotation of the rotating sleeve 11, the rotating sleeve 11 rotates and rotates with the second threaded rod 10 to perform thread engagement transmission. The rotating sleeve 11 moves downward along the second threaded rod 10, and the rotating sleeve 11 drives the first connecting piece 1 2. The first connecting member 12 drives the first telescopic cylinder 13 and the groove cutter 14 in sequence; when the rotating sleeve 11 moves down to the lower end of the second telescopic column 15 and is just separated from the clamping groove 111, the rotating sleeve 11 loses the restriction of the second telescopic column 15 and cannot move further downward, and the first rotating motor 9 is turned off. At this time, the lower end of the groove cutter 14 is flush with the lower end surface of the connecting block, so that the groove cutter 14 is squeezed into contact with the circumferential wall of the upper end surface of the rotating roller; then the first rotating shaft 3 is rotated to drive the turntable 4, the centering clamping assembly, and the rotating roller to rotate in sequence, and at the same time, the first threaded rod 5 is rotated to drive the first slider 6 to perform thread engagement transmission, and at the same time, the first telescopic cylinder 13 is turned on to push the groove cutter 14 downward to cut the threaded rope groove on the circumferential wall of the rotating roller; through the above process, the position of the groove cutter 14 can be automatically adjusted according to the different diameters of the rotating roller, so that rope grooves on the circumferential wall of the rotating roller with different diameters can be processed, thereby improving the degree of automation and work efficiency.

[0032] In order to facilitate the automatic control of the rotation of the first rotating shaft 3 and the first threaded rod 5, and to keep the two in a certain motion relationship to process the threaded rope groove on the peripheral wall of the rotating roller, the first rotating shaft 3 away from the turntable 4 is fixedly sleeved with a first gear 17 placed coaxially, and both ends of the first threaded rod 5 are fixedly sleeved with a second gear 18 placed coaxially, the diameter of the first gear 17 is larger than the diameter of the second gear 18, and an annular synchronous toothed belt 19 is sleeved between the first gear 17 and the second gear 18. A mounting seat is fixed on any support plate 2, and a second rotating motor 20 is fixed on the mounting seat. The output end of the second rotating motor 20 is fixed to one end of the first rotating shaft 3 close to the mounting seat.

[0033] Turn on the second rotating motor 20, and the output end of the second rotating motor 20 drives the first rotating shaft 3, the turntable 4, the centering clamping assembly, and the rotating roller to rotate in sequence. At the same time, the first rotating shaft 3 drives the first gear 17, and in turn drives the annular synchronous toothed belt 19, the second gear 18, the first threaded rod 5, the first slider 6, the second rotating motor 20, the second threaded rod 10, the rotating sleeve 11, the first connecting piece 12, the first telescopic cylinder 13, and the groove cutter 14 to move, and cooperate with the rotation of the rotating roller to process the thread rope groove.

[0034] The second telescopic column 15 is just separated from the card slot 111. When the first rotating motor 9 is turned off, the second threaded rod 10 cannot stop rotating immediately due to inertia. At this time, the rotating sleeve 11 rotates around the central axis of the second threaded rod 10.

[0035] In order to avoid the rotational offset of the first connecting member 12 and the change of the position of the groove cutter 14, a third telescopic column 21 is fixed to the lower end surface of the first slider 6. The third telescopic column 21 is placed coaxially with the first telescopic cylinder 13, and the lower end of the third telescopic column 21 is fixed to the upper end surface of the first connecting member 12; this can prevent the rotation of the first connecting member 12 from causing the position of the groove cutter 14 to shift.

[0036] In order to facilitate the clamping and fixing of the rotating roller to be processed, and to ensure that the central axis of the rotating roller is located directly below the groove cutter 14 when processing rotating rollers of different diameters, the turntable 4 is set to a hollow shell shape, and the centering clamping assembly includes a third gear 22, and there are two third gears 22 and they correspond one to one with the turntable 4. The third gears 22 are coaxially placed with the turntable 4 and are located inside the turntable 4. The third gears 22 are rotatably connected with the turntable 4, and the third gears 22 are meshed with a pair of straight racks 23 that are centrally symmetrically placed about the central axis of the turntable 4. A pair of parallel first slide grooves 41 are provided on the shell wall of the turntable 4 on one side. The first slide grooves 41 are coaxially placed with the straight racks 23 and correspond one to one with the straight racks 23. A second slider 24 is provided for sliding engagement, the second slider 24 corresponds one-to-one with the straight rack 23, and the second sliders 24 are fixedly connected to the corresponding straight rack 23. A pair of symmetrically placed triangular groove plates 25 are provided on one side of the turntable 4 close to each other, the triangular groove plates 25 correspond one-to-one with the second sliders 24, and the triangular groove plates 25 are fixed to the corresponding second sliders 24. The triangular groove plates 25 can move along the axial direction of the first slide groove 41. A second telescopic cylinder 26 is fixedly installed in the turntable 4. The second telescopic cylinder 26 is coaxially placed with the first slide groove 41. The bottom of the second telescopic cylinder 26 is fixed to the inner peripheral wall of the turntable 4. The telescopic rod of the second telescopic cylinder 26 is fixedly connected to a fixed block 27, and the fixed block 27 is fixedly connected to any straight rack 23.

[0037] Open the second telescopic cylinder 26 telescopic rod to extend and retract, the second telescopic cylinder 26 telescopic rod drives the fixed block 27, the fixed block 27 drives the straight rack 23 to which it is fixed, the straight rack 23 moves to drive the third gear 22, the third gear 22 drives another straight rack 23, the two straight racks 23 move to drive the second slider 24, the second slider 24 drives the two triangular slot plates 25, and by controlling the extension and retraction of the telescopic rod of the second telescopic cylinder 26, the two triangular slot plates 25 are controlled to move closer or farther away from each other. When the two triangular slot plates 25 are close to each other to squeeze the roller, the roller to be processed is easily clamped and fixed. At the same time, due to the action of the triangular slot plates 25, and when processing rollers of different diameters, the center axis of the roller is located directly below the slot cutter 14.

[0038] In order to facilitate the conveying of the rotating roller during the processing, a conveying mechanism is provided, which includes a bottom plate 28, on which a pair of first fixed plates 29 placed vertically upward are provided. The first fixed plates 29 are placed parallel to the support plate 2, and the first fixed plates 29 correspond to the support plates 2 one by one. The first fixed plates 29 are fixed to the lower ends of the corresponding support plates 2, and the first fixed plates 29 are provided with a coaxially placed first conveying tooth plate 30 on one side close to each other. The upper end of the first conveying tooth plate 30 is in the shape of a plurality of evenly distributed right-angled teeth, and the inclination of the right-angled teeth The surface direction is from the end away from the support plate 2 to the end close to the support plate 2, obliquely downward, the first conveying tooth plates 30 are fixedly connected to the first fixed plate 29 on the corresponding side through the second fixed plate 31, and a pair of symmetrically placed second conveying tooth plates 32 are provided between the two first conveying tooth plates 30. The second conveying tooth plates 32 are placed parallel to the first conveying tooth plates 30, and the evenly distributed right-angled teeth on the upper ends of the second conveying tooth plates 32 are equal in size and correspond one to one with those on the first conveying tooth plates 30. A third fixed plate 33 is fixed between the second conveying tooth plates 32;

[0039] The rotating roller to be processed is placed in from the end away from the support plate 2. This process can be carried out in conjunction with the conveyor belt mechanism in the prior art. The rotating roller falls into the two adjacent right-angled tooth gaps of the conveying mechanism farthest from the support plate 2, and then the third fixed plate 33 is lifted upward. The third fixed plate 33 drives the second conveying tooth plate 32 to move upward, and the second conveying tooth plate 32 moves upward to drive the rotating roller to move upward. When the right-angled tooth inclined surface in the second conveying tooth plate 32 rises to be flush with the other right-angled tooth inclined surface of the first conveying tooth plate 30, the rotating roller slides along the inclined surface into the right-angled tooth of the first conveying tooth plate 30 away from the second outer side of the support plate 2 end, and at the same time, the second conveying tooth plate 32 is moved down for reset; the above process is repeated continuously, so that the rotating roller passes through the adjacent right-angled teeth in turn and continuously approaches the support plate 2, so as to facilitate the conveying of the rotating roller during the processing.

[0040] In order to facilitate the control of the lifting and lowering of the third fixed plate 33, a coaxially arranged second slide groove 331 is opened on the third fixed plate 33. A pair of symmetrically placed roller rods 34 are fixed to the bottom of the third fixed plate 33. Wedge blocks 35 are provided on the roller rods 34. The inclination direction of the inclined surface of the wedge blocks 35 is the same as the inclination direction of the inclined surface of the right-angled teeth. The inclined surfaces of the wedge blocks 35 can be squeezed and contacted with the peripheral wall of the roller rod 34. The wedge blocks 35 pass through the second slide groove 331 and can slide along the second slide groove 331. A third connecting member 36 is fixed between the two wedge blocks 35. A mounting block is fixed on the bottom plate 28. A third telescopic cylinder 37 is fixed on the mounting block. The third telescopic cylinder 37 is coaxially placed with the second slide groove 331. The telescopic rod of the third telescopic cylinder 37 is fixed to the third connecting member 36.

[0041] When the third telescopic cylinder 37 is turned on, the telescopic rod of the third telescopic cylinder 37 extends and pushes the third connecting member 36. The third connecting member 36 drives the wedge block 35. The wedge block 35 is squeezed and contacted with the side wall of the roller rod 34, so that the roller rod 34 continuously rises along the inclined surface of the wedge block 35, and the roller rod 34 drives the third fixed plate 33 to move upward; when the third fixed plate 33 needs to be reset, the telescopic rod of the third telescopic cylinder 37 is retracted to reset, which can drive the wedge block 35, the roller rod 34, and the third fixed plate 33 to reset, thereby facilitating the control of the lifting and lowering of the third fixed plate 33.

[0042] During the relative sliding process between the roller rod 34 and the wedge block 35 due to the inclined surface extrusion, in order to prevent the roller rod 34 from moving in the horizontal direction, a pair of vertically placed limit rods 38 are fixed on the bottom plate 28, and the limit rods 38 pass through the third fixed plate 33 and are slidably connected to the third fixed plate 33; the limit rods 38 are used to improve the guidance of the movement of the third fixed plate 33, thereby preventing the roller rod 34 from moving in the horizontal direction.

[0043] In order to facilitate the loading and unloading of the centering clamping assembly, the ends of the first conveying tooth plate 30 and the second conveying tooth plate 32 close to the end of the support plate 2 are both located directly below the centering clamping assembly, and directly below the centering clamping assembly are the end right-angled teeth of the first conveying tooth plate 30 and the second conveying tooth plate 32 close to the end of the support plate 2. A pair of fourth telescopic cylinders 39 placed vertically upward are fixed on the bottom plate 28, and the two fourth telescopic cylinders 39 are both located between the two second conveying tooth plates 32. A pallet 40 is fixedly connected to the telescopic rod of the fourth telescopic cylinder 39. The length of the pallet 40 is less than the distance between the two second conveying tooth plates 32. An isosceles trapezoidal groove with a larger upper end and a smaller lower end is provided on the upper end surface of the pallet 40. The inclined surface inside the groove is parallel to the inclined surface of the right-angled teeth, and when the telescopic rod of the fourth telescopic cylinder 39 is fully retracted, the pallet 40 is completely below the inclined surface of the right-angled teeth directly below the centering clamping assembly;

[0044] Preferably, the fourth telescopic cylinder 39 can be a multi-stage telescopic cylinder; before loading, the fourth telescopic cylinder 39 is first turned on, and the telescopic rod of the fourth telescopic cylinder 39 is partially extended to make the inner inclined surface of the groove flush with the inclined surface of the right-angled teeth. When the conveying mechanism conveys the rotating roller to the bottom of the centering clamping assembly, the rotating roller rolls down into the groove through the right-angled tooth inclined surface, and then the telescopic rod of the fourth telescopic cylinder 39 continues to move upward to make it enter the clamping range of the centering clamping assembly for clamping; when it is necessary to unload the rotating roller that has been processed in the centering clamping assembly, the tray 40 is first raised to the bottom of the processed rotating roller, and the centering clamping assembly releases the clamping of the rotating roller. The pallet 40 is held so that it falls on the pallet 40, and then the telescopic rod of the fourth telescopic cylinder 39 drives the pallet 40 and the rotating roller to move downward. During the downward movement, since the length of the pallet 40 is less than the distance between the two second conveying tooth plates 32, and when the telescopic rod of the fourth telescopic cylinder 39 is fully retracted, the pallet 40 is completely below the right-angled tooth bevel directly below the centering clamping assembly. Before the fourth telescopic cylinder 39 is fully retracted, the two ends of the rotating roller will first be squeezed and contacted with the right-angled tooth bevel during the downward movement, and the rotating roller will continuously move out of the groove. After the pallet 40 is completely below the angle tooth bevel, the rotating roller slides and is discharged along the right-angled tooth bevel directly below the centering clamping assembly, completing the unloading work.
