[0024] See also Figure 1-Figure 4 The utility model provides a cold-drawn shaft grinding device, comprising a base 1, a fixed mounting seat 11 is fixed on one side above the base 1, and a movable mounting seat 12 is provided on the other side through a driving mechanism 4, the driving mechanism 4 is used to drive the movable mounting seat 12 to translate left and right, a limiting roller 3 is installed on a first U-shaped frame 13 fixed on the top of the fixed mounting seat 11, and a grinding roller 2 is installed on a second U-shaped frame 14 fixed on the top of the movable mounting seat 12, a second driving device 6 for driving the limiting roller 3 to rotate is provided on the side of the first U-shaped frame 13, and a first driving device 5 for driving the grinding roller 2 to rotate is provided on the side of the second U-shaped frame 14, the length of the grinding roller 2 and the limiting roller 3 is greater than the length of the cold-drawn shaft, ensuring that the grinding area length of the grinding roller 2 is sufficient to cover the cold-drawn shaft, V-shaped support members 7 are symmetrically provided on both sides between the grinding roller 2 and the limiting roller 3, and the two ends of the cold-drawn shaft are placed in the V-shaped support members 7 on both sides to support the cold-drawn shaft.

[0025] When using the present grinding device to grind the cold-drawn shaft, firstly, the two ends of the cold-drawn shaft are respectively placed on the V-shaped support member 7, and it is ensured that the outer wall of one side of the cold-drawn shaft is in contact with the grinding roller 2 to support the cold-drawn shaft. Subsequently, the driving mechanism 4 is used to push the grinding roller 2 toward the side of the limiting roller 3 until the cold-drawn shaft is clamped. Subsequently, the first driving device 5 and the second driving device 6 are used to drive the grinding roller 2 and the limiting roller 3 to rotate respectively. Under the action of friction, the shaft body is driven to rotate, and the rotating grinding roller 2 can grind the outer wall of the shaft body. Since the length of the grinding roller 2 is sufficient to cover the cold-drawn shaft, the outer periphery of the cold-drawn shaft is ground. After grinding, the two ends of the shaft body are cut off to obtain the ground cold-drawn shaft parts.

[0026] Specifically, the driving mechanism 4 includes a threaded rod 41, a first driving motor 42 and a nut seat 43. A guide groove 401 is provided on the upper surface of the base 1. The threaded rod 41 is rotatably installed in the guide groove 401. The first driving motor 42 is fixed to the side of the base 1, and the output shaft is fixedly connected to one end of the threaded rod 41. The nut seat 43 is limitedly slidably installed in the guide groove 401 and is threadedly mounted on the threaded rod 41. The dynamic mounting seat 12 is fixed to the top of the nut seat 43. The threaded rod 41 is driven to rotate by the operation of the first driving motor 42. The rotating threaded rod 41 drives the nut seat 43 to slide within the guide groove 401, thereby driving the dynamic mounting seat 12, the second U-shaped frame 14 and the grinding roller 2 to achieve left and right translation as a whole.

[0027] Specifically, brackets 121 are fixed on both sides of the guide groove 401 on the base 1, guide rods 122 are fixed on the sides of the brackets 121, and sliding blocks 123 are slidably mounted on the two guide rods 122. The lower surface of the dynamic mounting seat 12 is fixedly connected to the tops of the two sliding blocks 123. During the translation adjustment of the dynamic mounting seat 12, the sliding blocks 123 can be driven to slide synchronously along the guide rods 122. The sliding cooperation between the sliding blocks 123 and the guide rods 122 provides a guiding and limiting effect for the translation of the dynamic mounting seat 12, thereby ensuring that the translation of the dynamic mounting seat 12 is smooth and stable enough.

[0028] Specifically, the first driving device 5 includes a first fixed seat 51, a second driving motor 52 and a first mounting shaft 53. The second driving motor 52 is fixed to the side of the second U-shaped frame 14 through the first fixed seat 51; the first mounting shaft 53 is rotatably mounted on the second U-shaped frame 14, and the grinding roller 2 is fixedly sleeved on the first mounting shaft 53. The output shaft of the second driving motor 52 is fixedly connected to one end of the first mounting shaft 53. When the second driving motor 52 works, its output shaft can drive the first mounting shaft 53 and the grinding roller 2 to rotate, that is, provide drive for the rotation of the grinding roller 2.

[0029] Specifically, the second driving device 6 includes a second fixed seat 61, a third driving motor 62 and a second mounting shaft 63. The third driving motor 62 is fixed to the side of the first U-shaped frame 13 through the second fixed seat 61. The second mounting shaft 63 is rotatably mounted on the first U-shaped frame 13. The limiting roller 3 is fixedly sleeved on the second mounting shaft 63. The output shaft of the third driving motor 62 is fixedly connected to one end of the second mounting shaft 63. When the third driving motor 62 works, its output shaft can drive the second mounting shaft 63 and the limiting roller 3 to rotate, thereby providing stable drive for the rotation of the limiting roller 3.

[0030] Specifically, a first side frame 8 and a second side frame 83 are fixed on both sides of the fixed mounting seat 11, a first adjusting screw 82 is matched and installed in the first screw hole 81 provided on the first side frame 8, and a guide rod 85 is slidably installed in the sliding hole 84 provided on the second side frame 83, the first adjusting screw 82 is rotatably connected to the guide rod 85, and the cross-sections of the guide rod 85 and the sliding hole 84 are respectively rectangular shapes that match each other. A vertically extending column 9 is arranged on the two guide rods 85, a top seat 91 is fixed on the top of the column 9, and a mounting arm 92 is fixed on the side of the top seat 91, and the V-shaped support member 7 is fixed on the end of the mounting arm 92. By screwing the first adjusting screw 82, the guide rod 85 can be driven to slide and adjust, and then the V-shaped support member 7 can be driven to adjust left and right. In addition, the cross-sections of the sliding hole 84 and the guide rod 85 are rectangular, which plays a limiting role to prevent the guide rod 85 from rotating and affecting the supporting effect of the V-shaped support member 7 on the cold-drawn shaft.

[0031] Specifically, the guide rod 85 is provided with a second screw hole 93 and a guide hole 95 that pass through the upper and lower parts. A second adjusting screw 94 is threadedly installed in the second screw hole 93. The top end of the second adjusting screw 94 is rotatably connected to the bottom of the column 9. A sliding rod 96 is slidably installed in the guide hole 95. The top end of the sliding rod 96 is fixedly connected to the lower surface of the top seat 91. By screwing and adjusting the second adjusting screw 94 and under the guiding and limiting action of the sliding rod 96 and the guide hole 95, the column 9 and the top seat 91 can be driven to be raised and lowered.

[0032] By adjusting the V-shaped support member 7 to the left and right or to the up and down position, the position of the V-shaped support member 7 can be fine-tuned to meet the grinding needs of cold-drawn shafts of different diameters. At the same time, the V-shaped support member 7 is arranged in a V shape and can also support cold-drawn shafts of different diameters, with high versatility.

[0033] Specifically, a rubber sleeve (not shown in the figure) is fixedly mounted on the outer surface of the limiting roller 3. By arranging the rubber sleeve outside the limiting roller 3, it has the effect of deformation buffer protection when the cold-drawn shaft is excessively squeezed, thereby avoiding defects caused by excessive pressure on the outer surface of the cold-drawn shaft.
