[0002] A roll grinding machine is a metal cutting machine tool consisting of a bed, headstock, tailstock, carriage, longitudinal and transverse slides, grinding head, measuring frame, and electrical numerical control system. It is divided into five subsystems: a load-bearing system, a drive system, a grinding system, a measuring system, and a control system. The workpiece is supported by the headstock, tailstock, and carriage, and is driven to rotate by the headstock. Based on a mathematical model of the generatrix of the roll surface, the numerical control system controls the machine tool to perform multi-axis composite motion, achieving grinding of the roll surface metal by the grinding wheel during the motion. The online measuring system feeds back the measurement data to the grinding machine control system in real time, and the control system then performs closed-loop control of the machine tool to complete the precision machining of the workpiece.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-4 The roll grinding machine tilting and supporting mechanism shown includes a machining bed 1. The machining bed 1 has a movable tailstock tilting device 3 and a headstock tilting device 8 at both ends. The tailstock tilting device 3 and the headstock tilting device 8 are fixed at both ends of the roll diameter of the roll 5. A grinding machine 4 for grinding the roll 5 and a CNC center 7 fixed at one end of the machining bed 1 are provided on one side of the machining bed 1. A lifting device 6 for supporting the roll 5 is fixedly connected inside the machining bed 1. The lifting device 6 includes a base plate 61 fixed to the inner wall of the machining bed 1. A connecting device is provided on the top surface of the base plate 61. A damping device is provided between the base plate 61 and the connecting device. Two adjustable support devices for lifting the roll 5 are provided on the top surface of the connecting device. A locking device for the lifting device 6 is provided on one side of the support device.

[0020] To address the problem that existing roll 5 support brackets require frequent replacements based on the diameter of the roll 5, resulting in cumbersome roll 5 processing procedures, this utility model proposes a roll grinding machine tilting and supporting mechanism. This mechanism includes a lifting device 6 fixedly connected inside the processing bed 1 to support the roll 5. The top of the lifting device 6 has a connecting device, and the top of the connecting device has two adjustable support devices that can support the roll 5 for different diameters. This eliminates the need for frequent replacements of the lifting device 6 to support the roll 5, reducing the number of processing steps required for the roll 5.

[0021] like Figure 4 As shown, the shock absorption device includes a spring 63 fixedly connected to the top surface of the base plate 61, a guide rod 64 fixed to the top surface of the base plate 61 at the top of the spring 63, and a limiting circular plate 641 at the top of the guide rod 64.

[0022] The damping device can prevent the lifting device 6 from rigidly connecting the roll 5, and prevent the roll 5 from being irregularly round, which would cause noise when the roll 5 rotates, thus generating noise during the processing.

[0023] like Figure 4 As shown, the connecting device includes a connecting plate 62 that is slidably connected to two guide rods 64 respectively, a support column 621 that is fixedly connected to the top surface of the connecting plate 62, and a top plate 65 that is fixedly connected to the top end of the support column 621.

[0024] like Figure 4 As shown, a guide groove is provided on the top surface of the top plate 65, and a bidirectional lead screw 66 is rotatably connected in the guide groove. Two sliders 672 are threadedly connected to the outer periphery of the bidirectional lead screw 66. The support device includes a mountain-shaped support frame 67 fixedly connected to the top surface of the two sliders 672. Two rollers 671 are rotatably connected inside the mountain-shaped support frame 67.

[0025] The rotation of the bidirectional lead screw 66 drives the slider 672 to move towards or away from each other, which can fit the outer wall of the roll 5 to facilitate the rotation of the roll 5.

[0026] like Figure 4 As shown, the locking device includes a worm gear 661 fixedly connected to a two-way lead screw 66 on one side of the top plate 65, a worm 68 rotatably connected to the worm gear 661 at one end of the top plate 65, and a turntable 681 at one end of the worm 68.

[0027] The turntable 681 can drive the worm 68 to rotate, the rotation of the worm 68 can drive the worm wheel 661 to rotate, and the rotation of the worm wheel 661 can drive the bidirectional lead screw 66 to rotate, thereby realizing the adjustment of the lifting device 6.

[0028] like Figure 2As shown, the headstock tilting device 8 includes a support platform 2 81 fixed to the inner wall of the machining bed 1. A transmission box 84 is fixedly connected to the top surface of the support platform 2 81. A pneumatic gripper 2 85 is rotatably connected to one side of the transmission box 84. A transmission rod is fixedly connected to one side of the pneumatic gripper 2 85. A pulley 83 passing through the transmission box 84 is fixedly connected to one end of the transmission rod. A drive motor 82 is fixedly connected to the bottom of the support platform 2 81. A belt 86 is rotatably connected between the output end of the drive motor 82 and the pulley 83.

[0029] When the roll 5 is rotating, the drive motor 82 is started first. The drive motor 82 drives the pulley 83 to rotate through the belt 86. The rotation of the pulley 83 drives the pneumatic gripper 85 at one end of the transmission rod to rotate, thereby realizing the rotation of the roll 5.

[0030] like Figure 3 As shown, the tailstock tilting device 3 includes a support platform 31 set inside the machining bed 1. The bottom of the support platform 31 is provided with a guide wheel 36 adapted to the guide rail 2. A servo motor 34 is fixedly connected to the bottom of the support platform 31. A drive gear 341 is fixedly connected to the output end of the servo motor 34. A toothed plate 21 adapted to the drive gear 341 is fixedly connected inside the machining bed 1. A support box 32 is fixedly connected to the top surface of the support platform 31. A pneumatic gripper 33 for fixing the diameter of the roll 5 is rotatably connected to one side of the support box 32. A fixing pin 35 is threadedly connected to the protruding plate on one side of the support platform 31. The bottom end of the fixing pin 35 abuts against the top surface of the toothed plate 21.

[0031] When fixing the roll 5, the roll 5 is first lowered to the top of the lifting device 6 by hoisting. At this time, the roll diameter at one end of the roll 5 is fixed to the tailstock flipping device 3 by the pneumatic gripper 33. Then, the servo motor 34 is started to drive the drive gear 341 to move along the tooth plate 21 until the roll diameter at the other end of the roll 5 is inserted into the inner wall of the pneumatic gripper 85 for fixing. At this time, the support platform 31 is positioned by rotating the fixing pin 35 to prevent the support platform 31 from moving when the roll 5 is rotating.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
