Description

Technical Field

[0001] This utility model belongs to the field of spherical tank production technology, and specifically relates to an auxiliary tooling for inspecting weld seams of spherical tanks. Background Technology

[0002] "Spherical tank" usually refers to a spherical storage tank, which is a pressure vessel widely used in the industrial field. The auxiliary tooling for spherical tank weld inspection is a special equipment used to efficiently, accurately and safely complete the non-destructive testing of welds in spherical storage tanks. It mainly solves the problems caused by the curved surface structure of spherical tanks, such as difficulty in detection positioning, high risk of high-altitude operation and poor data consistency.

[0003] Existing auxiliary tooling for inspecting weld seams of spherical tanks involves placing the tank to be inspected on an inspection table, then driving the grippers to approach and fix the tank, followed by inspection of the weld seam by an external inspection agency. However, in actual use, the clamping and fixing direction of the tank is relatively unidirectional, and the rounded shape of the tank can cause it to slip to some extent during inspection, which affects the weld seam inspection to a certain extent. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an auxiliary tooling for inspecting the weld seams of spherical tanks. By bringing the lower and upper jaws close to the spherical tank to be inspected from multiple directions, the spherical tank is clamped and fixed from multiple directions, both from the lower and upper sides, in order to facilitate the inspection of the weld seams of the spherical tank.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an auxiliary tooling for inspecting weld seams of spherical tanks, including an inspection table, the inspection table including a turntable rotatably mounted on the inspection table, a plurality of evenly distributed sliding grooves opened on the upper surface of the turntable, a sliding seat slidably mounted inside each sliding groove, a lower chuck provided on the side of each sliding seat near the vertical center of the inspection table, a sliding rail provided on the upper surface of each sliding seat, a lifting seat slidably mounted inside each sliding rail, an upper chuck provided on the side of each lifting seat near the vertical center of the inspection table; an adjusting screw is rotatably mounted inside each sliding rail, the adjusting screw is threadedly connected to the adjacent lifting seat, a servo motor is mounted on the upper surface of each sliding rail, and the output shaft of the servo motor is fixed to the adjusting screw by a coupling.

[0006] As a further improvement of this utility model, each slide groove is rotatably equipped with an adjusting screw two, which is threadedly connected to the adjacent sliding seat. Each slide groove is rotatably equipped with a rotating shaft, which is fixed to the adjacent adjusting screw two via a coupling. The outer arc surface of each rotating shaft is fixedly fitted with a bevel gear one. The center of the turntable is rotatably equipped with a bevel gear two via a rotating shaft, and the bevel gear one is threadedly connected to the bevel gear two. A drive box is provided in the center of the lower surface of the turntable. A worm gear is fixedly fitted on the lower side of the outer arc surface of the rotating shaft. A worm is rotatably equipped inside the drive box, and the worm is meshed with the worm gear. A servo motor two is provided on the outside of the drive box, and the output shaft of the servo motor two is fixed to the worm via a coupling.

[0007] As a further improvement of this utility model, a bevel gear ring is fixedly sleeved on the outer arc surface of the turntable, and a support plate is provided at the top of the inner part of the testing table. A bevel gear three is rotatably provided on the support plate through a support shaft, and the bevel gear three is meshed with the bevel gear ring. A servo motor three is provided between the support plate and the testing table, and the output shaft of the servo motor three is fixed to the support shaft through a coupling.

[0008] As a further improvement of this utility model, the front side of the testing platform is provided with symmetrically distributed door panels, and the lower surface of the testing platform is provided with multiple support legs.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the second servo motor is controlled to operate. By adjusting the thread relationship between the second lead screw and the sliding seat, the sliding seat drives the lower jaw to move towards the vertical center of the testing platform, so that the lower jaw synchronously approaches the spherical tank and clamps and fixes the lower side of the spherical tank.

[0011] Secondly, the servo motor is controlled to run, and then the thread relationship between the lead screw and the lifting seat is adjusted to drive the lifting seat to move downward, thereby causing the lifting seat to drive the upper jaw to move downward synchronously to clamp and fix the upper side of the spherical tank.

[0012] Thirdly, through the cooperation between servo motor one and servo motor two, the spherical tank can be clamped and fixed from multiple directions, both below and above, to facilitate the inspection of the weld seams of the spherical tank.

[0013] Fourth, the meshing relationship between the bevel gear three and the bevel ring drives the turntable where the bevel ring is located to rotate, which in turn causes the spherical tank being clamped to rotate, thereby causing the spherical tank to rotate and allowing for the inspection of the weld seam of the spherical tank.

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, the system includes a testing table 101, which includes a turntable 201 rotatably mounted on the testing table 101. The upper surface of the turntable 201 has multiple evenly distributed sliding grooves 202. Sliding seats 203 are slidably mounted inside each sliding groove 202. Each sliding seat 203 has a lower chuck 204 on its side near the vertical center of the testing table 101. A sliding rail 205 is mounted on the upper surface of each sliding seat 203. A lifting seat 206 is slidably mounted inside each sliding rail 205. An upper chuck 207 is mounted on the side of each lifting seat 206 near the vertical center of the testing table 101. An adjusting screw 208 is rotatably mounted inside each sliding rail 205. The adjusting screw 208 is threadedly connected to an adjacent lifting seat 206. A servo motor 209 is mounted on the upper surface of each sliding rail 205. The output shaft of the servo motor 209 is fixed to the adjusting screw 208 via a coupling.

[0022] like Figure 3 , 4As shown, each slide groove 202 has a second adjusting screw 301 rotatably mounted inside, and the second adjusting screw 301 is threadedly connected to the adjacent sliding seat 203. Each slide groove 202 has a rotating shaft 302 rotatably mounted inside, and the rotating shaft 302 is fixed to the adjacent second adjusting screw 301 by a coupling. The outer arc surface of each rotating shaft 302 is fixedly fitted with a first bevel gear 303. The inner center of the turntable 201 has a second bevel gear 304 rotatably mounted through a rotating shaft, and the first bevel gear 303 is threadedly connected to the second bevel gear 304. The lower surface of the turntable 201 has a drive box 305 in the middle, and the lower side of the outer arc surface of the rotating shaft is fixedly fitted with a worm gear 306. The drive box 305 has a worm 307 rotatably mounted inside, and the worm 307 meshes with the worm gear 306. The outer side of the drive box 305 has a second servo motor 308, and the output shaft of the second servo motor 308 is fixed to the worm 307 by a coupling.

[0023] like Figure 2 , 4 As shown, a bevel gear ring 401 is fixedly sleeved on the outer arc surface of the turntable 201, and a support plate 402 is provided at the top of the inner part of the detection table 101. A bevel gear 403 is rotatably mounted on the support plate 402 via a support shaft. The bevel gear 403 meshes with the bevel gear ring 401. A servo motor 404 is provided between the support plate 402 and the detection table 101. The output shaft of the servo motor 404 is fixed to the support shaft via a coupling.

[0024] like Figure 1 , 2 As shown, the front side of the testing platform 101 is provided with symmetrically distributed door panels 103, and the lower surface of the testing platform 101 is provided with multiple support legs 102.

[0025] In use, the spherical can to be tested is placed on the upper surface of the turntable 201. Then, the servo motor 2 308 is controlled to run, so that the output shaft of the servo motor 2 308 drives the worm gear 307 connected to it to rotate. Then, through the meshing relationship between the worm gear 307 and the worm wheel 306, the rotating shaft is driven to rotate. Then, the rotating shaft drives the bevel gear 2 304 to rotate. Through the meshing relationship between the bevel gear 2 304 and the bevel gear 1 303, the bevel gear 1 303 is driven to rotate. Then, the bevel gear 1 303 drives the adjusting screw 2 301 to rotate.

[0026] The servo motor 209 is controlled to run, so that the output shaft of the servo motor 209 drives the adjusting screw 208 connected to it to rotate. Then, by adjusting the thread relationship between the adjusting screw 208 and the lifting seat 206, the lifting seat 206 is driven to move downward, which in turn causes the lifting seat 206 to drive the upper jaw 207 to move downward synchronously to clamp and fix the upper side of the spherical tank.

[0027] By cooperating with servo motor 209 and servo motor 308, the spherical tank can be clamped and fixed from multiple directions, both below and above, to facilitate the inspection of the weld seams of the spherical tank.

[0028] Then, the servo motor 3 404 drives the bevel gear 3 403 connected to it to rotate. Through the meshing relationship between the bevel gear 3 403 and the bevel gear ring 401, the turntable 201 where the bevel gear ring 401 is located is driven to rotate, so that the turntable 201 drives the clamped spherical tank to rotate, thereby causing the spherical tank to rotate and inspect the weld of the spherical tank.
