[0033] In order to solve the problem that the uneven port of the tubular metal member affects the welding quality when the tubular metal member of the ship body is welded by using the clamping plate type positioning device, please refer to Figures 1-7 , the following preferred technical solutions are provided:

[0034] A tooth groove 21 is processed on the outer wall of the fixed end of the positioning calibration cylinder 2, a driving gear 15 engaged with the tooth groove 21 is movably arranged on the side wall of the mounting plate 14 below the positioning calibration cylinder 2, a stepping motor is fixedly connected to the outer wall of the side of the mounting plate 14 away from the driving gear 15, the transmission shaft of the stepping motor is connected with the driving gear 15 to drive the positioning calibration cylinder 2 to rotate, the stepping motor is a forward and reverse motor, and the maximum stroke rotates one circle, and a centering assembly 22 is fixedly connected to the inner wall of the positioning calibration cylinder 2 in uniform intervals.

[0035] The centering assembly 22 comprises a U-shaped seat 221 fixedly connected to the inner wall of the positioning calibration cylinder 2 in uniform intervals, a deflection rod 222 movably connected between the inner walls of the side of the U-shaped seat 221 away from the port of the positioning calibration cylinder 2, a T-shaped rod 223 movably arranged between the inner walls of the other end of the U-shaped seat 221, guide grooves 2211 respectively formed in the two end side walls of the U-shaped seat 221 on the outer side of the deflection rod 222, the top rod of the T-shaped rod 223 movably clamped in the guide grooves 2211, a U-shaped groove formed in the bottom of the deflection rod 222, the overlapping part of the U-shaped groove and the lower end of the T-shaped rod 223 movably provided with a pin shaft, the pin shaft movably provided with a U-shaped plate 224 at the end, the U-shaped plate 224 movably provided with a clamping rod 225 at the bottom, the clamping rod 225 movably provided with a reset spring 226 at the two sides of the outer wall, the clamping rod 225 movably provided with an extrusion wheel 227 at the bottom, the top rod of the T-shaped rod 223 movably provided with a pull strip 228 at the two ends on the outer side of the guide grooves 2211, the pull strip 228 movably provided with a cross-shaped rod 229 between the end side walls, and the cross-shaped rod 229 movably connected to the inner wall of the positioning calibration cylinder 2 at the top end.

[0036] The deflection rod 222, the T-shaped rod 223 and the clamping rod 225 are arranged in Y shape, when the reset spring 226 is in normal relaxation state, the top rod of the T-shaped rod 223 is located at the end of the guide groove 2211 away from the deflection rod 222; the cross-shaped rod 229 is arranged in an inclined manner, and the inclined lower end of the vertical rod of the cross-shaped rod 229 faces the port of the positioning calibration cylinder 2, at this time, the vertical rods of all the cross-shaped rods 229 in the positioning calibration cylinder 2 form a conical cylinder structure.

[0037] Specifically, the ship body tubular metal member to be welded is placed on the top of the auxiliary supporting plate 5, and the two ends thereof are sleeved on the top of the positioning and aligning cylinder 2 suspended on the two sides of the auxiliary supporting plate 5. The vertical rods of all the cross-shaped rods 229 in the positioning and aligning cylinder 2 form a conical cylindrical structure and are inserted into the ports of the ship body tubular metal member. The vertical rods of all the cross-shaped rods 229 are simultaneously inclined and attached to the port edges of the ship body tubular metal member. The control rotating motor drives the bidirectional screw rod 12 to drive the moving block 13 to slide in the limiting groove 11, so as to control the mounting plate 14 to drive the positioning and aligning cylinder 2 to move towards the ship body tubular metal member. The mounting plates 14 at the two ends of the ship body tubular metal member press the same towards the middle. The ship body tubular metal member reversely drives the cross-shaped rods 229 to deflect. When the cross-shaped rods 229 deflect, the T-shaped rod 223 top rod is pulled to slide in the guide groove 2211 by the stay 228 to approach the deflection rod 222, so as to control the deflection rod 222 and the T-shaped rod 223 to move to approach the ship body tubular metal member, so that the end of the clamping rod 225 pressing wheel 227 is attached to the ship body tubular metal member to clamp and fix the same. At this time, the inclination of all the cross-shaped rods 229 in the positioning and aligning cylinder 2 is increased. The vertical rods of the cross-shaped rods 229 form a conical cylindrical structure and are still attached to the port edges of the ship body tubular metal member to clamp and fix the same under the pressing of the mounting plate 14, so as to realize the automatic centering and clamping of the ship body tubular metal member and ensure the clamping stability of the ship body tubular metal member in the welding process.

[0038] In order to further promote the clamping stability of the ship body tubular metal member, as shown in the embodiment, the following technical solutions are provided. Figures 5-7

[0039] The pressing wheel 227 comprises an intermediate column 2271 movably connected to the bottom of the clamping rod 225 and a flexible shell 2272 coaxially and fixedly connected to the outer wall of the intermediate column 2271. The inner wall of the flexible shell 2272 is uniformly and spacedly fixedly connected with elastic air bags 2273. The outer wall of the flexible shell 2272 is uniformly provided with air inlet holes 2274 in communication with the elastic air bags 2273. The outer walls on the two sides of the elastic air bags 2273 are respectively fixedly connected with air outlet valve nozzles 2275. The end of the elastic air bag 2273 is fixedly connected with a fixed plate 2276. The outer wall of the intermediate column 2271 is respectively provided with mounting grooves 2277 corresponding to the fixed plate 2276. The inner wall of the mounting groove 2277 and the outer wall of the fixed plate 2276 are fixedly connected with spring rods 2278. The spring rods 2278 are made of a material with high strength and are not easily deformed.

[0040] The outer wall of the flexible shell 2272 on the outer side of the elastic air bag 2273 is uniformly and spacedly provided with air outlet holes. When the flexible shell 2272 is not deformed by pressing, the elastic air bag 2273 and the spring rod 2278 are both in normal relaxation state.

[0041] ​Specifically, when the extrusion wheel 227 is clamped to the hull tubular metal member, the flexible shell 2272 is elastically extruded and deformed as it rolls, and the flexible shell 2272 is in flat contact with the outer wall of the hull tubular metal member at the contact end. At this time, the air inlet hole 2274 of the flat part of the flexible shell 2272 is sealed to the hull tubular metal member, and the deformed part of the flexible shell 2272 pushes the spring rod 2278 to compress the elastic air bag 2273 therebetween. After the elastic air bag 2273 is compressed, the internal gas is discharged through the air outlet valve 2275 to form a negative pressure, and the elastic air bag 2273 absorbs the hull tubular metal member through the air inlet hole 2274 under the action of the negative pressure to increase the clamping stability. When the hull tubular metal member is pulled out of the positioning calibration cylinder 2, the extrusion wheel 227 rolls along the outer wall of the hull tubular metal member. After the air inlet hole 2274 is separated from the outer wall of the hull tubular metal member, the elastic air bag 2273 can be restored by filling air through the air inlet hole 2274 for subsequent use, which is convenient to use.

The electric push rod 24 is movably connected to the outer walls of the two ends of the positioning calibration cylinder 2, and the outer wall of the flip cover 23 is uniformly and spacedly fixedly connected to the first clamping part 25. The electric push rod 24 controls the opening and closing of the flip cover 23 to switch the different clamping and positioning use states of the positioning calibration cylinder 2 to the hull tubular metal member or the irregular metal part.

[0044] The first clamping part 25 includes a fixed seat 251 uniformly and spacedly fixedly connected to the outer wall of the flip cover 23, and an elastic cloth pocket 252 fixedly connected to the outer wall of the fixed seat 251. The inside of the elastic cloth pocket 252 is filled with fine sand, and the filling amount of the fine sand is two-thirds of the elastic cloth pocket 252. The inner cavity of the elastic cloth pocket 252 is uniformly and spacedly provided with a gourd mouth 253. The fixed seat 251 is fixedly connected to a restraining rope 254 on one end of the side wall. The other end of the restraining rope 254 is spirally movably penetrated through the fixed seat 251 and fixedly connected to the other end of the side wall of the fixed seat 251. The restraining rope 254 is wrapped around the outside of the elastic cloth pocket 252.

[0045] Specifically, when the auxiliary positioning and clamping of the irregular metal part is needed, the electric push rod 24 pulls the flip cover 23 to close the port of the positioning calibration cylinder 2, at this time the irregular metal part is placed on the top of the auxiliary supporting plate 5, when the positioning calibration cylinder 2 moves close to the irregular metal part, the positioning calibration cylinder 2 pushes the elastic cloth bag 252 filled with fine sand to clamp and contact the outer wall of the irregular metal part on both sides through the cooperation of the flip cover 23, after preliminary clamping, the irregular metal part is rotated one circle to invert the elastic cloth bag 252, so that the fine sand in the elastic cloth bag 252 uniformly leaks under the action of the gourd mouth 253, the fine sand at the upper part of the elastic cloth bag 252 is refilled to the lower part, and each section of the elastic cloth bag 252 is adaptively accumulated and expanded according to the contact with the gap of the outer wall of the irregular metal part, so that each section of the elastic cloth bag 252 is expanded to better fit the outer wall of the irregular metal part, thereby ensuring the stable clamping and positioning of the irregular metal part.

[0048] The second clamping part 3 comprises a fixed disc 31 fixedly connected to the top of the mounting plate 14 on both sides of the corner, a U-shaped frame 32 fixedly connected to the middle part of the outer wall of the side away from the positioning calibration cylinder 2, a drive motor 33 fixedly connected to the side wall of the U-shaped frame 32, a driving gear 34 movably arranged on the outer wall of the middle part of the fixed disc 31 and fixedly connected to the output end of the drive motor 33, four groups of same positioning shafts 35 movably arranged on the outer wall of the fixed disc 31 on the outside of the driving gear 34 at uniform intervals, a driven gear 36 fixedly connected to the outer wall of the positioning shaft 35 and engaged with the driving gear 34, the driven gear 36 is in a square shape, and an L-shaped rod 37 fixedly connected to the other side of the fixed disc 31 after the positioning shaft 35 extends through the other side, and a roller 38 movably sleeved on the outer wall of the L-shaped rod 37.

[0049] Specifically, when the ship plate metal member needs to be positioned and clamped for welding, the ship plate metal member to be welded is placed on the top of the auxiliary supporting plate 5, the height of the auxiliary supporting plate 5 is controlled by the hydraulic lifting seat 4, so that the ship plate metal member is located between the gaps of the upper and lower two rows of L-shaped rods 37 on the side wall of the fixed disc 31, at this time, the two-way screw rod 12 is controlled to drive the moving block 13 to cooperate with the mounting plate 14 to push the L-shaped rod 37 to move to the ship plate metal member, so that the upper and lower two rows of L-shaped rods 37 on the side wall of the fixed disc 31 are respectively suspended on the upper and lower sides of the ship plate metal member, and the ship plate metal member is driven to be along the side wall of the fixed disc 31, then the driving motor 33 is started to drive the driving gear 34 to rotate, the driving gear 34 meshes with the driven gear 36 to cooperate with the positioning shaft 35 to synchronously drive the four groups of L-shaped rods 37 to rotate, and the spacing of the end rollers 38 is adjusted when the L-shaped rods 37 rotate, so as to clamp the ship plate metal member, and the ship plate metal member is placed on the outer wall of the rollers 38 of the plurality of L-shaped rods 37 at the same height, which fully guarantees the clamping stability of the ship plate metal member, and can be suitable for welding and clamping positioning of ship plate metal members of different thicknesses, and is convenient to use.
