[0045] The following will be combined with the drawings of the specific embodiments of the utility model to clearly and completely describe the exemplary scheme of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the relevant field.

[0046] like Figure 1 As shown, the simple steel sleeve outer surface grinding machine of this embodiment includes a mounting seat 110, a mounting frame 100, a first clamping mechanism 200, a second clamping mechanism 300 and a grinding mechanism 400. The mounting frame 100 is welded above the mounting seat 110, and a mounting platform 120 is welded on the upper surface of the mounting frame 100. The first clamping mechanism 100 and the second clamping mechanism 300 are relatively mounted on the outer sides of the left and right ends of the steel sleeve 500 to clamp the steel sleeve 500 together. The grinding mechanism 400 is fixedly arranged on the mounting seat 110, and is used to grind the outer surface of the steel sleeve 500.

[0047] like Figure 2 As shown, the grinding mechanism 400 includes a grinding base 440, a longitudinal moving assembly 430, a transverse moving assembly 420 and a grinding machine 420. The longitudinal moving assembly 430, the transverse moving assembly 420 and the grinding machine 410 are sequentially installed on the top of the grinding base 440 from bottom to top. The longitudinal moving assembly 430 is used to drive the grinding machine 410 to move along the axial direction of the steel sleeve 500, so as to ensure that the grinding wheel 4101 can grind the outer surface of the entire steel sleeve 500 along the axial direction; the transverse moving assembly 420 is used to drive the grinding machine 4101 to move along the radial direction of the steel sleeve 500 to adjust the contact degree between the grinding wheel 4101 and the steel sleeve 500, thereby adjusting the grinding degree of the outer surface of the steel sleeve 500.

[0048] like Figure 5 As shown, the longitudinal moving assembly 430 includes a first motor 4308 fixed to the grinding base 440 by bolts, the output shaft of the first motor 4308 is connected to the first screw rod 4304 through a coupling 4307, and the first screw rod 4304 is rotatably mounted on the grinding base 440 through first bearings 4306 at its left and right ends. A first screw nut 4305 is screwed to the first screw rod 4304.

[0049] Furthermore, an internal thread is provided at the center of the first nut seat 4305 , and the internal thread is meshed with the thread of the first screw rod 4304 , so as to ensure that the first nut seat 4305 can move along the first screw rod 4304 when the first screw rod 4204 rotates.

[0050] The first guide rails 4301 welded to the grinding base 440 are arranged in parallel on the front and rear sides of the first screw rod 4304, and the first slider 4302 is slidably sleeved on the top of the first guide rail 4301. The first slider 4302 is connected and fixed to the transverse movement assembly 420 through the first ear plates 4303 on both sides thereof, thereby driving the transverse movement assembly 420 and the grinding wheel machine 410 to move along the first guide rail 4301.

[0051] like Figure 3 and 4As shown, the traverse assembly 420 includes a bottom plate 4201, which is welded to the first screw nut 4305. A second bearing 4204 is fixedly installed on the upper left portion of the bottom plate 4201, a second screw rod 4206 is passed through the middle of the second bearing 4204, and a second slide rail 4202 welded to the bottom plate 4201 is parallelly arranged on the front and rear sides of the second screw rod 4206. A second slider 4203 is slidably sleeved on the top of the second slide rail 4202, and the second slider 4203 is fixedly connected to the grinder 410 through the second ear plates 4214 on both sides thereof. The left end of the first screw rod 4206 is fixedly connected to the hand wheel 4205 through a pin key.

[0052] A second nut seat 4207 is screwed onto the second screw rod 4206 . A baffle plate 4211 which is sleeved on the second screw rod 4206 is arranged on the right side of the second nut seat 4207 . The top surfaces of the second nut seat 4207 and the baffle plate 4211 are both welded to the grinder 410 .

[0053] Furthermore, an internal thread is provided at the center of the second nut seat 4207 , which meshes with the thread of the second screw rod 4206 , ensuring that when the second screw rod 4206 rotates, the second nut seat 4207 moves along the second screw rod 4206 , thereby driving the grinder 410 to move along the second slide rail 4202 .

[0054] A vertical plate 4210 is welded to the upper right part of the bottom plate 4201, and an externally threaded rod 4212 coaxial with the second screw rod 4206 is fixed to the left side of the vertical plate 4210. Further, a pressure plate 4213 is arranged on the right side of the vertical plate 4210, and screw holes are provided in the centers of the vertical plate 4210 and the pressure plate 4213, and an internally threaded groove is provided in the center of the right end of the externally threaded rod 4212, and bolts are sequentially passed through the pressure plate 4213, the vertical plate 4210 and the externally threaded rod 4212 to fix the externally threaded rod 4212.

[0055] A spring pressure ring 4209 is screwed onto the external threaded rod 4212, and a spring 4208 which is sleeved on the second screw rod 4206 is fixedly connected to the inner side of the spring pressure ring 4209, and the end of the spring 4208 is against the baffle 4211. Furthermore, an internal thread is provided at the center of the spring pressure ring 4209, and the internal thread is meshed with the thread of the external threaded rod 4212, which not only ensures that the spring pressure ring 4209 can be stably installed on the external threaded rod 4212, but also can rotate the spring pressure ring 4209 to drive the spring 4208 to move along the second screw rod 4206 to adjust the contraction degree of the spring 4208 (determined by the vibration generated by the grinding wheel machine). The elastic force generated by the contraction of the spring 4208 will push the baffle 4211, thereby slowing down the vibration generated when the grinding wheel 4101 rotates, thereby improving the stability of the grinding wheel 4101 when it rotates.

[0056] like Figure 6As shown, the first clamping mechanism 200 and the second clamping mechanism 300 both include a clamping drive portion 290 and a clamping frame 220 , and the clamping drive portion 290 is fixed to the mounting seat 110 by bolts.

[0057] The clamping drive unit 290 includes a second motor 230, the output shaft of which is connected to a third screw rod 250 via a second coupling 240, and the third screw rod 250 is fixed to the mounting seat 110 via a third bearing 260. A third nut seat 280 is screwed onto the third screw rod 250, and the clamping frame 220 is welded and fixed to the top of the third nut seat 280. A third motor 270 is mounted on the clamping frame 220, and a cone head 210 is fixedly connected to the output end of the third motor 270. When the second motor 230 is started, the third screw rod 250 is driven to rotate, thereby driving the cone head 210 on the upper part of the clamping frame 220 to move axially along the steel sleeve 500.

[0058] Furthermore, an internal thread is provided at the center of the third nut seat 280, which meshes with the thread of the third screw rod 250, ensuring that when the third screw rod 250 rotates, the third nut seat 280 will move along the third screw rod 250, thereby driving the clamping frame 220 and the cone head 210 to move axially along the steel sleeve 500.

[0059] Preferably, the cone head 210 is trapezoidal in shape, so as to facilitate clamping of steel sleeves 500 of different diameters.

[0060] Furthermore, the third motor 270 drives the steel sleeve 500 to rotate through the cone head 210 , and the rotation direction is opposite to the rotation direction of the grinding wheel 4101 .

[0061] How this application works is:

[0062] First, the steel sleeve 500 is placed between the two cone heads 210. The second motor 230 is started to make the two clamping frames 220 move relative to each other, and at the same time drive the two cone heads 210 to move relative to each other until the two cone heads 210 can stably clamp the steel sleeve 500.

[0063] Secondly, the hand wheel 4205 is turned to rotate the second screw rod 4206, and the grinding machine 410 is driven to approach the steel sleeve 500 through the second screw nut 4207 until the grinding wheel 4101 is in contact with the outer surface of the steel sleeve 500. Then, according to the vibration magnitude previously measured by the grinding machine 410, the spring pressure ring 4209 is turned to adjust the elastic force of the spring 4208, thereby reducing the vibration generated when the grinding wheel 4101 rotates, and improving the stability of the grinding wheel 4101 when rotating.

[0064] Next, the third motor 270 is started to drive the steel sleeve 500 to rotate through the cone head 210; the grinding wheel motor 4102 is started to drive the grinding wheel 4101 and the cone head 210 to rotate in the opposite direction, and the outer surface of the steel sleeve 500 is started to be ground.

[0065] Finally, the first motor 4308 is started to rotate the first screw rod 4304. At the same time, the first screw nut 4305 drives the traverse assembly 420 and the grinder 410 to move axially along the steel sleeve 500, thereby achieving the overall grinding of the outer surface of the steel sleeve 500 by the grinding wheel 4101.

[0066] After the outer surface of the steel sleeve 500 is ground, the first motor 4307, the second motor 230 and the grinding wheel motor 4102 are turned off in sequence, and the hand wheel 4205 is turned to separate the grinding wheel 4101 from the outer surface of the steel sleeve 500, thereby disassembling the ground steel sleeve 500.
