Description

Technical Field

[0001] The utility model relates to the technical field of gauges, in particular to a high-precision profile welding gauge. Background Art

[0002] With the development of welding technology, welding equipment is also constantly undergoing technological innovation and upgrading. At present, profile weldments need to be inspected by welding inspection tools after welding. Since two profiles are welded at an angle, if there is a large deviation in the angle of the profile after welding and the accuracy is not high, the welded profile will be unusable.

[0003] After welding, the existing profiles are generally inspected manually by taking a protractor. However, the degree needs to be read every time during the manual measurement, which leads to low inspection efficiency. Moreover, if a reading error occurs during the measurement, the subsequent use quality of the profile will be affected. Therefore, a high-precision profile welding inspection fixture is proposed. Utility Model Content

[0004] The utility model aims to solve the problem of low efficiency of profile inspection after welding in the prior art, and proposes a high-precision profile welding inspection tool.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-precision profile welding gauge comprises a support plate, a horizontal measuring rod is fixedly provided on the surface of the support plate, a U-shaped seat is fixedly provided at one end of the horizontal measuring rod, and an inclination measuring rod is provided inside the U-shaped seat, one end of the inclination measuring rod is rotatably connected to the U-shaped seat via a rotating shaft, a driving mechanism connected to the rotating shaft is provided on one side of the surface of the support plate, and angle measuring scale lines are provided on the surface of the support plate.

[0007] Preferably, the driving mechanism includes a screw, a screw seat, a rack and a gear, two fixed plates are symmetrically fixed on the surface of the support plate, the screw is arranged between the two fixed plates in a transversely rotatable manner, and a rotating handle is fixedly provided at one end of the screw, the side wall of the screw seat is threadedly connected to the rod wall of the screw through a threaded hole, one side of the screw seat is fixedly connected to the rack, the gear is fixedly arranged on one end of the rotating shaft, and the gear is meshed with the rack.

[0008] Preferably, a sliding rod is fixedly provided between the two fixing plates, and the side wall of the screw seat is slidably connected to the rod wall of the sliding rod through a sliding hole.

[0009] Preferably, the angle measuring scale line is an arc-shaped structure, and the center point of the angle measuring scale line coincides with the connection point between the horizontal measuring rod and the tilt measuring rod.

[0010] Preferably, two wall-hanging holes are symmetrically provided on one side of the surface of the support plate.

[0011] Preferably, the horizontal measuring rod and the tilt measuring rod are aligned with both side edges of the welded profile.

[0012] Compared with the prior art, the utility model provides a high-precision profile welding gauge, which has the following beneficial effects:

[0013] 1. The high-precision profile welding gauge has a support plate, a horizontal measuring rod, an inclination measuring rod and an angle measuring scale. The horizontal measuring rod and the inclination measuring rod form an angle, and the two rods can be rotated by a rotating shaft, so that the angle between the horizontal measuring rod and the inclination measuring rod can be adjusted. Then, the two welded profiles are directly placed close to the horizontal measuring rod and the inclination measuring rod. If the angles of the two welded profiles meet the standards, there will be no gap between the two profiles and the horizontal measuring rod and the inclination measuring rod. If there is a gap or the profiles cannot be placed between the horizontal measuring rod and the inclination measuring rod, it means that there is a large error between the two welded profiles and they do not meet the use standards.

[0014] 2. This high-precision profile welding inspection fixture is equipped with a screw, screw seat, rack, gear and handle. When it is necessary to adjust the angle of the horizontal measuring rod and the tilt measuring rod, the hand rotates the handle to rotate the screw. During the rotation of the screw, the screw seat is driven to move, so that the rack also moves. When the rack moves, it drives the gear to rotate, so that the angle of the tilt measuring rod on the shaft rotates. At this time, the angle is adjusted, which can be applied to welding inspection of profiles with different angles.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model is convenient for directly measuring the angle of the profile after welding, and can directly compare the angle of the profile without manual repeated measurement and reading, thereby improving the inspection efficiency of the profile.
