DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 A welding positioning auxiliary device for a pressure control tank includes a bracket 1; a regulating support device 2 for carrying the pressure control tank; and a driving device 4 for driving a positioning device 3 and a regulating support device 2 to adjust the position.

[0030] In this embodiment, the regulating support device 2 includes a supporting component, an arc device and a concentric self-adjusting component;

[0031] See also Figure 4 The support component includes a V bracket 201, on which a plurality of balls 202 and a rotating column 203 are arranged. The balls 202 are arranged to facilitate the rotation of the pressure control tank in the later stage. Otherwise, the excessive gravity will lead to increased friction, and the rotation of the pressure control tank in the later stage will be more laborious. The V bracket 201 is threadedly connected with a threaded rod 211. Two support components are arranged, and a connecting sleeve 209 is connected between the two support components. The connecting sleeve 209 is connected with a sliding sleeve 5, and the V bracket 201 slides on the sliding sleeve 5. The V bracket 201 can carry the cylindrical pressure control tank for the later clamping and positioning welding.

[0032] For further information, see Figure 4The concentric self-adjusting component includes two push rods 204, which are slidably connected to the V bracket 201. The bottom of the push rod 204 is abutted against a bottom plate 205, and the bottom plate 205 is connected to a pillar 206. The pillar 206 is slidably connected to the bracket 1, and a compression spring 207 is sleeved on the pillar 206. The bottom plate 205 is connected to the arc device. When the pressure control tank is loaded and clamped, the surface will form a pressing contact with multiple push rods 204, and finally the bottom plate 205 will be pressed downward by gravity. The bottom plate 205 will slide down on the bracket 1 through the pillar 206, and then drive the compression spring 207 to achieve compression, and the bottom plate 205 will drive the arc sleeve 208 to move downward, and then use the arc sleeve 208 to drive the arc rod 210 to move downward as a whole, and finally achieve the concentricity of the arc sleeve 208 and the pressure control tank, which is convenient for the later angle adjustment.

[0033] For further information, see Figure 4-Figure 6 The arc device includes an arc sleeve 208, which is slidably connected to the connecting sleeve 209 through a keyway, and the arc sleeve 208 is connected to the bottom plate 205. The arc sleeve 208 is internally slidably connected to an arc rod 210, and the arc rod 210 is connected to the positioning device 3. The arc sleeve 208 is threadedly connected with a locking screw 310 for fixing the position of the arc rod 210. When it is necessary to position some plates, the operator needs to drive the positioning sleeve 301 and the arc rod 210 to slide in a circle through the pull rod 309, so that the positioning device 3 rotates to the top of the pressure control tank, and then rotates the locking screw 310 to squeeze and position the arc rod 210. There are angle scales on both sides of the arc rod 210, and the operator can accurately know the rotation angle of the positioning device 3 according to the scales.

[0034] In addition, a positioning device 3 is used to position the welding fittings of the pressure control tank;

[0035] See also Figure 6The positioning device 3 includes a positioning sleeve 301, which is mounted on the arc rod 210. A slide plate 304 is slidably connected in the positioning sleeve 301, and a top sleeve 305 is rotatably connected to the slide plate 304. A sliding rod 306 is slidably connected in the top sleeve 305. An extrusion spring 307 is sleeved on the sliding rod 306. One end of the extrusion spring 307 is connected to the top sleeve 305, and the other end of the extrusion spring 307 is connected to the sliding rod 306. The other end of the sliding rod 306 is connected to a top sheet 308, and the top sheet 308 is slidably connected to the inside of the top sleeve 305. The operator places the accessories to be welded inside the top sleeve 305. If it is a pipe head, it is directly placed inside the cylindrical surface of the top sleeve 305. Then, as the elastic contraction of the extrusion spring 307, the sliding rod 306 will be driven to slide inside the top sleeve 305, and then the top sheet 308 is indirectly used to push the welding accessories against the surface of the pressure control tank, so as to achieve positioning without the assistance of multiple people, which can improve the overall welding efficiency of accessories.

[0036] In addition, see Figure 6 The positioning sleeve 301 is provided with scale lines, and the scale lines can provide the operator with parameters for regulation. The positioning sleeve 301 is connected with a pull rod 309, and the pull rod 309 is convenient for the operator to control the overall rotation angle. The slide plate 304 is threadedly connected with an adjusting screw 302, and the adjusting screw 302 is rotatably connected to the positioning sleeve 301. One end of the adjusting screw 302 is connected with a pinion 303. This scheme uses the rotation of the adjusting screw 302 to control the precise lateral movement of the slide plate 304, so the operator can achieve lateral displacement of the positioning device 3 according to the adjusting screw 302.

[0037] It is worth noting that see Figure 5-Figure 7 The driving device 4 includes a dial wheel 401, the bottom of which is connected to the transmission gear 212, which is connected to the threaded rod 211, and one side of the dial wheel 401 is rotatably connected to a connecting frame 403 through a support rod 402, which is fixed to the bracket 1, and a pressure rod 404 is fixedly connected to the bracket 1, and the support rod 402 is in pressure contact with the pressure rod 404. The pressure rod 404 is provided to limit the position of the dial wheel 401. When the operator turns the dial wheel 401 to rotate, according to different required conditions, when the threaded rod 211 is rotated, the operator needs to push the dial wheel 401 to rotate and apply force backward, so the support rod 402 will press and contact the position of the pressure rod 404, so the relative position of the dial wheel 401 will remain unchanged.

[0038] It is worth mentioning that please refer to Figure 7The bracket 1 is connected with a telescopic rod 407 through a connecting piece, one end of the telescopic rod 407 is connected with a sleeve rod 409, a sliding sleeve 410 is sleeved on the sleeve rod 409, one side of the sliding sleeve 410 is connected with a matching gear 408, the matching gear 408 is connected with a key shaft 411, and the key shaft 411 is slidably connected with the rotating column 203 through a key slot. When the pressure control tank needs to be angle controlled, the operator needs to toggle the swing rod 406 to drive the sleeve rod 409 on the telescopic rod 407 to move horizontally. When the telescopic rod 407 slides horizontally on the bracket 1 through the slide slot, it will drive the sliding sleeve 410 and the matching gear 408 to move horizontally. The telescopic rod 407 is connected with a swing rod 406, and one side of the thumbwheel 401 is connected with an inner gear sleeve 405. The thumbwheel 401 rotates at the connection between the support rod 402 and the connecting frame 403 to drive the inner gear sleeve 405 to synchronously mesh with the pinion 303 or the matching gear 408. In the initial stage, the mating gear 408 is not on the motion trajectory of the dial wheel 401, so the forward movement of the dial wheel 401 will form a motion meshing with the pinion 303. When the mating gear 408 is moved horizontally, the trajectory of the mating gear 408 is in front of the pinion 303, so the dial wheel 401 will mesh with the inner gear sleeve 405 on the mating gear 408 first. Therefore, the rotation at this time will drive the rotation of the key shaft 411 through the meshing of the gears, and finally drive the rotation of the pressure control tank on the rotating column 203, thereby finally realizing the change of the angle.

[0039] Working principle: first, the operator needs to place the pressure control tank on two V brackets 201 to form a V-shaped support, and the V bracket 201 slides on the sliding sleeve 5 through the keyway, and the sliding sleeve 5 is used to limit the rotation of the V bracket 201. After that, the surface of the pressure control tank will form a pressing contact with multiple push rods 204, and finally the bottom plate 205 will be pressed downward by gravity. The bottom plate 205 will slide down on the bracket 1 through the support 206, thereby driving the compression spring 207 to be compressed, and the bottom plate 205 will drive the arc sleeve 208 to move downward, and then use the arc sleeve 208 drives the arc rod 210 to move downward as a whole, and finally realizes the concentricity of the arc sleeve 208 and the pressure control tank. Then, according to the measurement reference, the dial wheel 401 can be turned to drive the rotation of the transmission gear 212, and the transmission gear 212 will drive the rotation of the threaded rod 211, and then use the threaded connection relationship to drive the lateral movement of the V bracket 201. At this time, the pressure control tank located on the V bracket 201 will move with the movement of the V bracket 201 until it moves to the calibration position, so the operator can turn the left or right dial wheel 401 according to the actual calibration point. Then the operator places the accessories to be welded inside the top sleeve 305. If it is a pipe head, it is directly set inside the cylindrical surface of the top sleeve 305. Then, with the elastic contraction of the extrusion spring 307, it will drive the sliding rod 306 to slide inside the top sleeve 305, and then indirectly use the top sheet 308 to push the welding accessories against the surface of the pressure control tank to achieve positioning. The operator can then weld according to the positioned position, and the entire process can be operated by one person without the assistance of multiple people. If the lateral position of the pipe head needs to be adjusted, the operator needs to turn the dial 401 to rotate the connection position of the support rod 402 and the connecting frame 403. In fact, the dial 401 is pulled forward, and then the internal gear sleeve 405 on the dial 401 is controlled to mesh with the pinion 303. Then, the dial 401 will be out of the meshing state of the transmission gear 212, and the pinion 303 will be driven alone to achieve meshing rotation, and then the adjusting screw 302 will be driven to rotate. The slide plate 304 is connected by threads, so at this time, the slide plate 304 will move laterally on its surface as the adjusting screw 302 rotates, and finally the lateral position of the welding accessory is accurately adjusted. Therefore, no matter where the welding accessory is in the pressure control tank, accurate positioning can be achieved. When the lateral distance adjustment is completed, if some plates need to be positioned, the operator needs to drive the positioning sleeve 301 and the arc rod 210 to slide in a circle through the pull rod 309, so that the positioning device 3 rotates to the top of the pressure control tank, and then rotates the locking screw 310 to squeeze and position the arc rod 210. There are angle scales on both sides of the arc rod 210, and the operator can accurately know the rotation angle of the positioning device 3 according to the scales. Afterwards, the same principle is used to use the elastic force of the top sheet 308 to shrink and squeeze the plate accessories to achieve extrusion fixation, which is convenient for subsequent operators to spot weld or weld.Because it is necessary to rotate the pressure control tank during the actual welding process, but it is inconvenient to control it manually because of its heavy weight, a matching gear 408 is provided. When the pressure control tank needs to be angle controlled, the operator needs to toggle the rocker 406 to drive the sleeve rod 409 on the telescopic rod 407 to move horizontally. When the telescopic rod 407 slides horizontally on the bracket 1 through the slide groove, it will drive the sliding sleeve 410 and the matching gear 408 to move horizontally so that they are located below the inner gear sleeve 405. At this time, the control dial 401 moves forward a certain distance and will mesh with the matching gear 408. Then, rotating the dial 401 will drive the matching gear 408 to rotate, and then use the keyway connection to drive the key shaft 411 to rotate. The key shaft 411 will drive the rotation of the rotating column 203. At this time, the surface of the pressure control tank will be in contact with the rotating column 203, so as the rotating column 203 rotates, it will drive the rotation of the pressure control tank, and finally realize the change of the angle. Therefore, in actual working conditions, the position of the positioning device 3 is first adjusted laterally, and then the rotation position of the pressure control tank is adjusted, and finally the angular position of the positioning device 3 is adjusted. The operator can flexibly adjust according to the actual welding conditions, and finally realize the auxiliary welding positioning of the accessories of the pressure control tank.
