[0002] With the development of intelligent manufacturing, the butt assembly of cylinders in developed countries has entered a new stage of pursuing high automation and high production efficiency, while the butt assembly of cylinders in China is still mainly manual. There are many problems with the existing horizontal assembly equipment for cylinders. For example, during the assembly process, the center of mass of the cylinder is offset, and the friction between the supporting mechanism and the cylinder causes the cylinder to roll. The cylinder is large in size and weight, and the roll generated is large, so it is impossible to limit the roll of the cylinder by pushing the device. At present, the assembly of cylinders relies on the process personnel and operators to explore the experience of cylinder rolling. Before assembly, the cylinder is adjusted to the corresponding angle horizontally. During the assembly process, the cylinder rolls freely. After the assembly is in place, the cylinder rolls to the horizontal. This method has poor reliability and leads to repeated assembly and exit operations, which seriously endangers the life safety of the operator. Summary of the invention

[0003] In response to the above problems, the present invention proposes an automatically retractable roll limit device for cylindrical assembly, which can limit the rolling of the cylinder during assembly; a pressure sensor is installed in the roll limit mechanism to detect the size of the rolling force during the cylindrical assembly process in real time; the roll limit mechanism is automatically retracted after the stop block is in place during the assembly process, thereby reducing the labor intensity of employees and improving work efficiency.

[0004] The present invention discloses an automatically retractable rolling limit device used in the assembly process of a cylinder, wherein the limit device comprises a rolling limit mechanism and a limit plate, wherein: The rolling limit mechanism is installed on the square steel guide rail of the assembly equipment. The rolling limit device is distributed on both sides of the cylinder. The rolling limit mechanism contacts the cylinder stop block to limit the rolling of the cylinder during assembly. The limit plate is installed on the rack of the assembly equipment and is used to control the automatic retraction of the rolling limit mechanism before the cylindrical stop block enters the cylinder; The upper plane of the square steel guide rail has a slope angle at a set distance in front of the limit plate to ensure that the roll limit mechanism descends here and prevent the cylindrical stop block from pressing on the roll limit mechanism, resulting in the limit plate being unable to automatically retract after contacting the roll limit mechanism.

[0005] Further, the rolling limit mechanism includes a slider seat, a limit block, a pressure sensor, a clamping seat, a limit shaft, a bearing seat, a first sliding bearing, a first spring, a second sliding bearing, a hand wheel, a roller bearing seat, a roller bearing, a second spring, a snap ring, a snap ring seat, and a third spring, wherein: The slider seat is installed across the square steel guide rail of the assembly equipment and the equipment rack, and the roller bearing is fixed on the slider seat through the roller bearing seat; the rolling limit mechanism is clamped on the rack of the assembly equipment and the square steel guide rail through the roller bearing and the slider seat, which is used to provide guidance for the linear motion of the rolling limit mechanism during the assembly process and prevent the rolling limit mechanism from tipping over due to the pressure of the cylindrical stop block; The limit block is placed on the slider seat, and the two sides of the limit block clamp the slider seat and move linearly along the slider seat; The pressure sensor is installed on the limit block, and the upper surface of the pressure sensor contacts the cylindrical stop block, which is used to limit the rolling of the cylinder during assembly and detect the rolling force of the cylinder in real time during assembly; The limiting shaft is installed in the first sliding bearing and the second sliding bearing, and is in contact with the limiting block through the clamping seat. The limiting shaft drives the limiting block to move linearly along the first sliding bearing and the second sliding bearing.

[0006] Furthermore, the limit device is also provided with a button mechanism, which includes a button shaft, a second spring, and a button cap. A shoulder is provided at one end of the button shaft, and the other end passes through the slider seat. The second spring is fixed on the button shaft, and the button cap is connected to the button shaft by a screw. During the assembly process, the second spring is in an extended state. The snap ring seat is fixed on the slider seat, the third spring and the snap ring base are fixed on the shaft of the snap ring seat, the front end face of the snap ring contacts the end face of the button shaft, the middle opening of the snap ring is used for the limiting shaft to pass through, and the third spring is in an extended state during assembly.

[0007] Furthermore, polytetrafluoroethylene is pasted on the surface of the slider seat to reduce the friction during the linear motion of the rolling limit mechanism.

[0008] Furthermore, after the cylindrical stop block is in place, the button cap contacts the limit plate and compresses the second spring, and the button shaft drives the retaining ring to move linearly, so that the retaining ring is separated from the limit shaft groove. Under the action of the first spring, the limit shaft drives the limit block to move linearly along the first sliding bearing and the second sliding bearing, and the rolling limit mechanism is separated from the cylindrical stop block.

DETAILED DESCRIPTION

[0013] The rolling limit mechanism 1 is installed on the square steel guide rail 6 of the assembly equipment to limit the rolling of the cylinder during assembly; The limit plate 2 is installed on the rack 5 of the assembly equipment, and is used to control the automatic retraction of the rolling limit mechanism 1 before the cylindrical stop block 4 enters the cylinder 3, without manual intervention; The upper plane of the square steel guide rail 6 has a slope angle of 2° at 200 mm in front of the limit plate 2, so as to ensure that the rolling limit mechanism 1 descends at this point, and to prevent the cylindrical stop block 4 from pressing on the rolling limit mechanism 1, so that the limit plate 2 cannot be automatically retracted after contacting the rolling limit mechanism 1; The rolling limit devices are distributed on both sides of the cylinder, and the rolling of the cylinder during assembly is limited by the contact between the rolling limit mechanism 1 and the cylinder stop block 4; The rolling limit mechanism 1 includes a slider seat 101, a limit block 102, a pressure sensor 103, a clamping seat 104, a limit shaft 105, a bearing seat 106, a first sliding bearing 107, a first spring 108, a second sliding bearing 109, a hand wheel 111, a roller bearing seat 112, a roller bearing 113, polytetrafluoroethylene 114, a button cap 115, a button shaft 116, a second spring 117, a snap ring 118, a snap ring seat 119, and a third spring 121, wherein: The slider seat 101 is installed on the square steel guide rail 6 of the assembly equipment, and the roller bearing 113 is fixed on the slider seat 101 through the roller bearing seat 112. The rolling limit mechanism 1 is clamped on the rack 5 of the assembly equipment and the square steel guide rail 6 through the roller bearing 113 and the slider seat 101, which is used to provide guidance for the linear motion of the rolling limit mechanism 1 during the assembly process and prevent the limit mechanism 1 from tipping over due to the pressure of the cylindrical stop block 4; The limit block 102 is placed on the slider seat 101 , and the two sides of the limit block 102 clamp the slider seat 101 , and can move linearly along the slider seat 101 .

[0014] The pressure sensor 103 is mounted on the limit block 102, and the upper surface of the pressure sensor 103 is in contact with the cylinder stop block 4, which is used to limit the rolling of the cylinder during assembly and detect the rolling force during the assembly of the cylinder in real time; The limiting shaft 105 is installed in the first sliding bearing 107 and the second sliding bearing 109, and is connected to the limiting block 102 through the clamping seat 104. The limiting shaft 105 can drive the limiting block 102 to move linearly along the first sliding bearing 107 and the second sliding bearing 109; The button shaft 116 has a shoulder at one end and the other end passes through the slider seat 101. The second spring 117 is fixed on the button shaft 116. The button cap 115 is connected to the button shaft 116 by screws. The second spring 117 is in an extended state during the assembly process. The snap ring seat 119 is fixed on the slider seat 101, the third spring 121 and the base of the snap ring 118 are fixed on the four shafts of the snap ring seat 119, the front end face of the snap ring 118 contacts the end face of the button shaft 116, the middle opening of the snap ring 118 is used for the limit shaft 105 to pass through, and the third spring 121 is in an extended state during the assembly process; The surface of the slider seat 101 is pasted with polytetrafluoroethylene 114 to reduce the friction during the linear motion of the rolling limit mechanism; The protruding ends on both sides of the limit block 102 are used to block the cylindrical stop block 4. When assembling, the cylindrical stop block 4 contacts the front end surface of the limit block 102, driving the rolling limit mechanism 1 to move forward together; when exiting, the cylindrical stop block 4 contacts the rear end surface of the limit block 102, driving the rolling limit mechanism 1 to move backward together; The hoisting deviation of the cylindrical stop block 4 is ≤±2mm, and the pressure sensor 103 is 3mm lower than the theoretical horizontal height of the lower end surface of the cylindrical stop block 4, ensuring that after the cylinder is hoisted in place, there is no interference between the rolling limit mechanism 1 and the cylindrical stop block 4. During the assembly process, the cylinder itself will roll. When it rolls to the cylindrical stop block 4 and contacts the pressure sensor 103 on one side, the rolling limit mechanism 1 can limit the cylinder from continuing to roll and monitor the rolling force; The limit shaft 105 is notched, and the cylinders at the two ends of the notch have a taper angle of 1°. When the operator presses the hand wheel 111 to make the limit shaft 105 drive the limit block 102 to move linearly along the first sliding bearing 107 and the second sliding bearing 109, the middle opening of the snap ring 118 encounters the notch of the limit shaft 105, and the snap ring 118 moves along the four axes of the snap ring seat 119 under the action of the third spring 121, so that the snap ring 118 clamps the main limit shaft 105, ensuring that the limit shaft 105 moves to the specified state and is locked; After the cylindrical stop block 4 is in place, the button cap 115 contacts the limit plate 2 and compresses the second spring 117. The button shaft 116 drives the retaining ring 118 to move linearly, so that the retaining ring 118 is separated from the notch of the limit shaft 105. Under the action of the first spring 108, the limit shaft drives the limit block 102 to move linearly along the first sliding bearing 107 and the second sliding bearing 109, and the rolling limit mechanism 1 is separated from the cylindrical stop block 4.
