Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a fault-proof detection welding fixture. Background Technology

[0002] In the process of producing workpieces, it is sometimes necessary to weld two ring-shaped workpieces together. Currently, a fixture is often used to limit and fix the two ring-shaped workpieces before welding. After welding, the weld needs to be inspected, which requires the use of a fault-proof inspection welding fixture.

[0003] A fault-proof welding fixture with publication number CN211277200U includes a fixed plate, a first mounting plate on the top of the fixed plate, a drive motor fixedly connected to the left side of the top of the first mounting plate, a first fixing sleeve fixedly connected to the output end of the drive motor, and a second electric telescopic rod fixedly connected to the left side of the top of the fixed plate. The output end of the second electric telescopic rod is fixedly connected to the connection point of the first mounting plate. This utility model comprises a fixed plate, a drive motor, a fixing ring, a first fixing sleeve, a second fixing sleeve, a first electric telescopic rod, a second electric telescopic rod, a fixed arc claw, a screw block, a rotating handle, and a screw rod.

[0004] The above-mentioned device can limit the ring-shaped workpiece and facilitate welding. However, when the above scheme limits the ring-shaped workpiece, it cannot position the center of the ring-shaped workpiece at the center of the fixed sleeve, resulting in rotational eccentricity. This causes the outer surface of the ring-shaped workpiece to not always be in contact with the welding gun when the fixed sleeve rotates, which greatly affects the welding efficiency. Furthermore, it is impossible to perform error prevention detection on the welding effect after welding is completed, and additional detection is required, making the entire welding and detection process more time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where the outer surface of the ring-shaped workpiece does not always contact the welding gun, which greatly affects the welding efficiency and makes it impossible to perform error prevention detection on the welding effect after welding. This requires additional detection, making the entire welding and detection process more time-consuming and labor-intensive. Therefore, this invention proposes an error prevention detection welding fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fault-proof welding fixture includes a worktable. A drive mechanism and two limiting mechanisms are disposed above the worktable. Each limiting mechanism includes a limiting ring, and two electric push rods are fixedly connected to the inner wall of the limiting ring. The output ends of both electric push rods are fixedly connected to limiting clamps. The drive mechanism includes a drive motor, and a connecting frame plate is fixedly connected to the output end of the drive motor. The right side of the connecting frame plate is fixedly connected to one of the limiting rings. An internal groove is formed inside the worktable, and a transverse transport block is slidably connected to the inner wall of the internal groove. A protective shell is disposed above the transverse transport block, and a flipping mechanism is disposed inside the protective shell. The flipping mechanism includes a bearing rotating block, the outer surface of which is rotatably connected to the protective shell. A weld detector is installed inside the bearing rotating block.

[0008] Preferably, the outer surface of the limiting ring is rotatably connected to a limiting frame, and the bottom surface of the limiting frame is fixedly connected to the upper surface of the worktable.

[0009] Preferably, a threaded rod is rotatably connected to the right side of the transverse transport block, the outer surface of the threaded rod is threaded to the worktable, and a turntable is fixedly connected to the right end of the threaded rod.

[0010] Preferably, an electric push rod 2 is installed inside the transverse moving block, and the output end of the electric push rod 2 is fixedly connected to the bottom surface of the protective shell.

[0011] Preferably, the inner top wall of the protective shell has a through hole.

[0012] Preferably, a connecting shaft is fixedly connected to the front of the bearing rotating block, the outer surface of the connecting shaft is rotatably connected to the protective shell, a flipping block is fixedly connected to the outer surface of the connecting shaft, and an opening is provided inside the flipping block.

[0013] Preferably, two magnet blocks are mounted on the front of the protective shell, and the outer surface of the flipping block is in contact with one of the magnet blocks.

[0014] Preferably, a connecting platform is fixedly connected to the outer surface of the drive motor, and the bottom surface of the connecting platform is fixedly connected to the upper surface of the workbench.

[0015] Compared with the prior art, this utility model provides a fault-proof detection welding fixture, which has the following beneficial effects:

[0016] 1. By using the cooperation between the limiting mechanism and the driving mechanism, this utility model can ensure that the center of the annular workpiece corresponds to the center of the limiting ring after the annular workpiece is limited. This prevents eccentricity when the drive motor drives the connecting frame plate to rotate, causing the limiting ring and the annular workpiece to rotate. The welding torch can maintain continuous contact with the annular workpiece, improving welding efficiency. By using the set weld seam detector, the welding status of the annular workpiece can be judged in time, so that the welding errors of the annular workpiece can be re-welded in time, improving welding efficiency.

[0017] 2. This utility model can rotate the connecting shaft and the bearing rotating block by rotating the flipping block, which in turn can make the bearing rotating block rotate the weld detector, thus flipping the weld detector and preventing the weld detector from being damaged by flying sparks during welding, thus protecting the weld detector.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 A fault-proof welding fixture includes a workbench 1. A drive mechanism 3 and two limiting mechanisms 2 are arranged above the workbench 1. The limiting mechanism 2 includes a limiting ring 202. Two electric push rods 203 are fixedly connected to the inner wall of the limiting ring 202. The output ends of the two electric push rods 203 are fixedly connected to the limiting clamping plates 204. The electric push rods 203 inside each limiting ring 202 should be controlled by the same controller. When limiting the ring workpiece, it can ensure that the ring workpiece is in its exact center.

[0027] The outer surface of the limiting ring 202 is rotatably connected to the limiting frame 201. The bottom surface of the limiting frame 201 is fixedly connected to the upper surface of the worktable 1. By using the limiting frame 201, the limiting ring 202 can be supported, so that the rotation of the limiting ring 202 can be limited.

[0028] The drive mechanism 3 includes a drive motor 301. The output end of the drive motor 301 is fixedly connected to a connecting frame plate 302. The right side of the connecting frame plate 302 is fixedly connected to one of the limiting rings 202. The outer surface of the drive motor 301 is fixedly connected to a connecting platform 303. The bottom surface of the connecting platform 303 is fixedly connected to the upper surface of the worktable 1. The connecting frame plate 302 is used to connect the limiting ring 202 and the output end of the drive motor 301. The connecting frame plate 302 is an arched part, which can reserve some space for the ring part.

[0029] The workbench 1 has an internal groove 4. A transverse carrier block 7 is slidably connected to the inner wall of the internal groove 4. A protective shell 9 is provided above the transverse carrier block 7. A flipping mechanism 12 is provided inside the protective shell 9. The flipping mechanism 12 includes a carrier rotating block 1204. The groove inside the protective shell 9 is adapted to the outer surface of the carrier rotating block 1204. The outer surface of the carrier rotating block 1204 is rotatably connected to the protective shell 9, so that the carrier rotating block 1204 can rotate inside the protective shell 9.

[0030] The weld detector 11 is installed inside the bearing rotating block 1204. A connecting shaft 1203 is fixedly connected to the front of the bearing rotating block 1204. The outer surface of the connecting shaft 1203 is rotatably connected to the protective shell 9. A flipping block 1201 is fixedly connected to the outer surface of the connecting shaft 1203. An opening 1202 is provided inside the flipping block 1201. By using the opening 1202, the flipping block 1201 can be rotated easily. The rotation of the flipping block 1201 can drive the connecting shaft 1203 and the bearing rotating block 1204 to rotate, thereby realizing the flipping protection of the weld detector 11.

[0031] Two magnet blocks 13 are installed on the front of the protective shell 9. The outer surface of the flip block 1201 is in contact with one of the magnet blocks 13. The magnet block 13 attracts the flip block 1201, which can limit the position of the opening 1202 and prevent the load-bearing flip block 1204 from rotating.

[0032] A threaded rod 5 is rotatably connected to the right side of the transverse transport block 7. The outer surface of the threaded rod 5 is threaded to the worktable 1. A turntable 6 is fixedly connected to the right end of the threaded rod 5. By using the cooperation between the threaded rod 5 and the turntable 6, the transverse position of the transverse transport block 7 can be adjusted, thereby adjusting the position of the weld detector 11.

[0033] An electric push rod 8 is installed inside the transverse moving block 7. The output end of the electric push rod 8 is fixedly connected to the bottom surface of the protective shell 9. By using the protective shell 9, the height of the protective shell 9 and the weld detector 11 can be adjusted, thereby facilitating the adjustment of the height and lateral position of the weld detector 11, making it easier to detect welds and prevent welding errors.

[0034] The inner top wall of the protective shell 9 has a through hole 10, which facilitates the weld inspection detector 11 to inspect the weld.

[0035] Working principle: When welding a ring-shaped workpiece, the workpiece is placed between two limiting clamps 204. Activating two electric push rods 203 moves the limiting clamps 204, thus positioning the workpiece so that its center aligns with the center of the limiting ring 202. After alignment, the drive motor 301 rotates the connecting frame plate 302 and one of the limiting rings 202. Welding is then performed using an external welding torch, allowing for convenient and quick uniform welding of the outer surface of the ring-shaped workpiece. Activating the second electric push rod 8 activates the protective shell 9 and through hole 10 to perform error detection on the weld seam of the outer surface of the ring-shaped workpiece, enabling reprocessing of any defective welds. By rotating the flipping block 1201, the connecting shaft 1203 and the bearing rotating block 1204 can be driven to rotate, which in turn causes the bearing rotating block 1204 to rotate the weld detector 11, thus flipping the weld detector 11 and preventing the weld detector 11 from being damaged by sparks during welding, thus protecting the weld detector 11.
