The movable sleeve 101 is cylindrical in shape, and the movable sleeve 101 is sleeved on the inner jacket 1013, and can move and / or rotate along the axial direction of the inner jacket 1013.

[0043] A plurality of positioning protrusions 1020 or positioning grooves are arranged on the front end surface of the movable sleeve, and the positioning protrusions 1020 or positioning grooves are arranged at equal intervals along the circumference of the movable sleeve.

[0044] The outer cylinder body 103, the inner cylinder body 104, the inner jacket 1013 or the outer jacket 102 are fixedly connected to the adjustable top plate 203 via a connecting piece.

[0045] An operating handle is provided on the side wall of the movable sleeve 101. A plurality of operating holes 1014 are provided on the side wall of the movable sleeve 101.

[0046] The existing roller is an assembly. When replacing the roller, it is often necessary to remove the entire roller from the rolling mill, or to remove the roller ring on the roller. When removing the roller ring, the roller pull rod 1019 in the roller must be pulled out so that the entire roller can be disassembled and the roller ring can be removed from the roller.

[0047] like Figure 7 and 8 As shown, Figure 7 and 8 The roller shaft structure is to be disassembled, and the left end of the roller shaft is provided with a left clamping flange 1016 and a right clamping flange 1017 for clamping the roller ring (not shown in the figure), the left end of the roller shaft is provided with a left clamping nut 1015, and the right end is provided with a right clamping nut 1018, the left clamping nut 1015 and the right clamping nut 1018 are connected by a roller shaft tie rod 1019, nuts are provided at the left and right ends of the roller shaft tie rod 1019, and a hexagon socket is provided at the right end of the roller shaft tie rod 1019.

[0048] like Figure 8 The roller shaft is provided with a spline 1021 and a movable sleeve positioning groove or a movable sleeve positioning protrusion 1022.

[0049] During operation, the right end of the roller is placed outside the rolling mill. Therefore, when the roller is disassembled as a whole, the outer jacket 102 and the inner jacket 1013 are sleeved around the contour of the right end of the roller. The outer jacket 102 has a larger diameter at the roller where it is sleeved, and the front end surface of the outer jacket is used to support the body of the rolling mill or the components on the roller, so as to limit the movement of the body and the components on the roller to the right. The inner jacket 1013 is sleeved on the spline 1021 of the roller shaft, and the positioning key in the inner jacket 1013 is embedded in the keyway of the spline 1021, and is used to limit the rotation of the roller shaft when the roller shaft is unloaded; when the inner jacket 1013 clamps the roller shaft, the movable sleeve 101 slides to the front end of the inner jacket 1013, and then the movable sleeve is rotated to make the positioning protrusion 1020 or the positioning groove at the front end of the movable sleeve embedded in the movable sleeve positioning groove or movable sleeve positioning protrusion 1022 on the roller shaft, and then the rotation of the movable sleeve is limited, and then the movable sleeve is fixedly connected to the roller shaft through bolts and other connecting parts, and then the roller can be unloaded;

[0050] When unloading the roller, the inner cylinder 104 moves backward, and the whole roller shaft can be pulled out of the rolling mill. Simultaneously, the moving mechanism 3 moves backward, and can play the effect of carrying the roller shaft, and can also assist in unloading the roller.

[0051] When the roller tie rod 1019 is pulled out, the outer hexagon of the front end of the tie rod 109 is inserted into the inner hexagon of the end of the roller tie rod 1019, driving the roller tie rod 1019 to rotate, so that the roller tie rod 1019 is disconnected from the left clamping nut 1015 and the right clamping nut 1018, and the right end of the roller tie rod 1019 is threadedly connected to the front end of the tie rod sleeve 107. After the connection is completed, the piston 1011 moves backward and presses against the tie rod sleeve stopper 108, so that the tie rod sleeve 107 moves backward. At the same time, the tie rod sleeve 107 presses against the tie rod 109 limit block, so that the tie rod 109 moves backward, and finally the entire roller tie rod 1019 is pulled out. Without the restriction of the left clamping nut 1015, the left clamping flange 1016 can be removed, and then the roller ring can be removed.

[0052] In the above structure, the left and right sides of the outer jacket 102 are cut off, so that the movable sleeve 101 can be adjusted to facilitate turning the handle. The movable sleeve 101 is provided with an operation hole 1014. When the roller needs to be pressurized to separate the components on the roller, air can be injected into the air holes on the roller through the operation hole 1014, or a nut or other connector can be inserted into the operation hole 1014 to connect the movable sleeve 101 to the roller, which can also facilitate the removal of the roller.

[0053] The front end of the tie rod 109 is matched with a hexagon socket nut 1012, which is threadedly connected to the inner wall of the tie rod sleeve 107; the hexagon socket nut 1012 is used to support the tie rod 109 and plays a guiding and positioning role. The inner cylinder body 104 is provided with a tie rod sleeve support block 105, and the tie rod sleeve stopper 108 is movably arranged in the tie rod sleeve support block 105, and the support block plays a guiding and positioning role for the tie rod sleeve 107.

[0054] A displacement sensor 1010 is provided between the piston 1011 and the rod sleeve support block 105. Due to the presence of the sensor, the pull-out length of the rod 109 can be better measured.

[0055] The displacement sensor 1010 includes a sensor head and a sensor body. The sensor head is inserted into the sensor body and can be extended and retracted in the sensor body. The sensor head is embedded in the piston 1011 , and the sensor body is embedded in the tie rod sleeve support block 105 .

[0056] The adjustment mechanism is located at the edge area of ​​the adjustment top plate 203 and the adjustment bottom plate 201 .

[0057] When the adjustment mechanism is an automatic adjustment structure such as a cylinder, the adjustment mechanism can be set in the middle of the adjustment top plate 203 and the adjustment bottom plate 201. However, when the adjustment mechanism is a manual adjustment mechanism, it is more convenient to operate if the adjustment mechanism is set at the edge, while it will affect the operation if it is set in the middle.

[0058] The adjusting top plate 203 and the adjusting bottom plate 201 are circular, and the adjusting mechanisms are evenly distributed at the edge areas of the adjusting top plate 203 and the adjusting bottom plate 201 .

[0059] Alternatively, the adjustment top plate 203 and the adjustment bottom plate 201 have the same shape, and both the adjustment top plate 203 and the adjustment bottom plate 201 are polygonal, and the adjustment mechanism is located at the top corners of the adjustment top plate 203 and the adjustment bottom plate 201 and / or at the center of each side of the adjustment top plate 203 and the adjustment bottom plate 201. Figure 2 As shown, the adjustment top plate 203 and the adjustment bottom plate 201 are quadrilaterals, and the adjustment mechanism is located at the top corners of the quadrilateral.

[0060] In this embodiment, the adjustment mechanism is a bolt assembly, which includes an adjustment bolt 202, an upper adjustment nut 204 and a lower adjustment nut 205; the adjustment bolt 202 passes through the adjustment top plate 203 and the adjustment bottom plate 201 from bottom to top, and is threadedly connected with the adjustment top plate 203 and the adjustment bottom plate 201, the upper adjustment nut 204 and the lower adjustment nut 205 are sleeved on the adjustment bolt 202, the lower adjustment nut 205 is located above the adjustment bottom plate 201, and the upper adjustment nut 204 is located below the adjustment top plate 203.

[0061] When the adjustment seat 2 is in use, the distance between the adjustment top plate 203 and the adjustment bottom plate 201 can be adjusted by adjusting the distance between the upper adjustment nut 204 and the lower adjustment nut 205, so as to achieve height adjustment and angle adjustment of the manipulator 1. When the distance between the upper adjustment nut 204 and the lower adjustment nut 205 on each adjustment bolt 202 is consistent, the adjustment top plate 203 and the adjustment bottom plate 201 are parallel to each other; when the distance between the upper adjustment nut 204 and the lower adjustment nut 205 on one or more adjustment bolts 202 is inconsistent, the adjustment top plate 203 deflects relative to the adjustment bottom plate 201.

[0062] Furthermore, the rear end of the screw rod 305 is connected to the screw rod driving device through a safety coupling 307 .

[0063] Due to the above structure, the screw rod 305 is connected to the screw drive device through the safety coupling 307. When the load on the sliding seat 304 is too large and the screw drive device cannot drive the sliding seat 304 to move, the safety coupling 307 will automatically disconnect the power transmission between the screw rod 305 and the screw drive device to ensure the safety of the screw drive device. When the load on the sliding seat 304 decreases, the safety coupling 307 automatically connects the screw rod 305 and the screw drive device to ensure power transmission, so that the screw drive device can drive the sliding seat 304 to move along the screw rod 305 on the main frame. Therefore, during use, when the roller shaft is stuck, the safety of the screw drive device can be guaranteed.

[0064] Further, the safety coupling 307 includes a screw connection part and a screw drive device connection part; the screw connection part includes a screw connection sleeve 3071, the front end of the screw connection sleeve 3071 is connected to the rear end of the screw 305, and the screw connection sleeve 3071 is fixedly sleeved with an elastic mechanism limit plate 3072 and a transmission plate 1 3075; the elastic mechanism limit plate 3072 and the transmission plate 1 3075 are arranged at intervals, and the transmission plate 1 3075 is located at the rear end of the screw connection sleeve 3071;

[0065] The screw drive device connection part includes a screw drive device connection sleeve 3074, the front end of the screw drive device connection sleeve 3074 is rotatably sleeved on the outside of the transmission disc 1 3075, and the rear end is connected to the screw 305 transmission device; the front end of the screw drive device connection sleeve 3074 is fixedly provided with a transmission disc 2 3076, and the transmission disc 2 3076 is rotatably sleeved on the screw connection sleeve 3071 and is located in front of the transmission disc 1 3075;

[0066] The screw connecting sleeve 3071 is sleeved with an elastic mechanism 3073, the front end of the elastic mechanism 3073 contacts the elastic mechanism limit plate 3072, and the rear end contacts the front end surface of the second transmission plate 3076. The elastic mechanism 3073 pushes the screw connecting sleeve 3071 and the screw driving device connecting sleeve 3074 away from each other, so that the rear end surface of the second transmission plate 3076 contacts the front end surface of the first transmission plate 3075. The elastic mechanism 3073 is a spring; in actual manufacturing, the screw connecting sleeve 3071, the elastic mechanism limit plate 3072, and the first transmission plate 3075 can be integrally formed; the screw driving device connecting sleeve 3074 and the screw driving device connecting sleeve 3074 can be integrally formed.

[0067] Due to the above structure, when the screw rod 305 and the screw rod driving device are connected, the rear end face of the transmission disk 2 3076 and the front end face of the transmission disk 1 3075 contact each other under the action of the elastic mechanism 3073. At this time, the power of the screw rod driving device can be transmitted to the screw rod 305 through the action of the friction force; when the load on the sliding seat 304 is too large, the maximum power output by the screw rod driving device is greater than the friction between the transmission disk 1 3075 and the transmission disk 2 3076, but is still insufficient to drive the sliding seat 304 to move, the transmission disk 1 3075 and the transmission disk 2 3076 will rotate relative to each other, disconnecting the power transmission between the screw rod 305 and the screw rod driving device, thereby ensuring the safety of the screw rod driving device.

[0068] Furthermore, the screw rod 305 passes through the sliding seat 304 , and a screw rod slider 3011 is matched and sleeved on the screw rod 305 , and the screw rod slider 3011 is fixedly connected to the sliding seat 304 .

[0069] Due to the above structure, the sliding seat 304 is connected to the screw rod 305 through the screw slider 3011, which is convenient for production and processing. The ready-made screw rod 305 nut mechanism can be directly purchased to avoid opening threads on the sliding seat 304, thereby reducing the processing difficulty.

[0070] Further, the main frame includes a base 301, a screw mounting seat 1 302, a screw mounting seat 2 306 and a screw drive device mounting seat 308; the screw mounting seat 1 302 is arranged at the front end of the base 301, the screw mounting seat 2 306 is arranged at the rear end of the base 301, and the screw 305 is rotatably arranged on the screw mounting seat 1 302 and the screw mounting seat 2 306; the screw drive device mounting seat 308 is fixedly arranged on the screw mounting seat 2 306 or the base 301, and the screw drive device is fixedly arranged on the screw drive device mounting seat 308. In order to ensure the smooth rotation of the screw 305, the screw 305 can be arranged on the screw mounting seat 1 302 and the screw mounting seat 2 306 through a bearing. In order to ensure the smooth rotation of the screw 305, the screw 305 can be arranged on the screw mounting seat 1 302 and the screw mounting seat 2 306 through a bearing.

[0071] The base 301 is provided with a guide rail 303, and the bottom of the sliding seat 304 is provided with a guide rail slider 3010, and the guide rail slider 3010 is slidably arranged on the guide rail 303. The number of the guide rail slider 3010 can be set to multiple. In this embodiment, as shown in FIG. Figure 2 As shown, two guide rail sliders 3010 are respectively arranged on the left and right sides of the base 301 .

[0072] The guide rail 303 has slots extending along the length direction thereof on both sides, and the guide rail slider 3010 has claws at the bottom; when the guide rail slider 3010 is matched and arranged on the guide rail 303, the claws are embedded in the slots and can slide along the slots.

[0073] Due to the above structure, the guide rail slider 3010 can be prevented from being separated from the guide rail 303, thereby ensuring the stable operation of the entire equipment.

[0074] The screw drive device includes a screw drive motor 3012 and a reducer 309 , and the screw drive motor 3012 is connected to the safety coupling 307 via the reducer 309 .
