Description

Technical Field

[0001] This utility model belongs to the field of profile inspection technology, and in particular relates to a profile bending inspection device. Background Technology

[0002] Profiles are long strips of material with specific cross-sections that are processed through rolling, extrusion and other processes. They have a wide range of applications. In the fields of construction and machinery manufacturing, they are often used as structural components to bear external forces and weight. In building decoration and furniture manufacturing, they can not only connect and fix but also enhance the aesthetics. In the automotive, shipbuilding and other industries, they can be processed into various parts.

[0003] Before using profiles, their curvature needs to be inspected. If the curvature of the profile does not meet the standard, it will be difficult to achieve precise matching with other components during installation. However, most of the existing profile curvature inspection methods on the market rely on manual operation, using template comparison or ruler measurement. These traditional inspection methods are not only difficult to guarantee accuracy, but also have low work efficiency.

[0004] To address this issue, we provide a profile bending inspection device to solve the problems mentioned above. Utility Model Content

[0009] The present invention is further configured such that the adjustable crossbar includes a slide plate and a sliding plate respectively fixedly connected to the opposite side of the two side frames, and the top of the sliding plate and the slide plate are flush with the bottom of the inner cavity of the fixed frame. A fixing screw is threaded onto one side of the slide plate and the fixing screw abuts against the side of the sliding plate.

[0010] The present invention is further configured such that the mounting rod includes an I-shaped rod and a U-shaped rod respectively fixedly connected to one side of the two fixed frames, and the U-shaped rod is movably inserted into the inside of the I-shaped rod.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1 and Figure 2 This utility model is a profile bending inspection device, including a base frame 100; the base frame 100 includes two side frames 101 and an adjustable crossbeam 102 fixed between the two side frames 101. A rectangular fixing frame 103 is fixed to the top of each of the two side frames 101. A mounting rod 104 is fixed to one side of each fixing frame 103. Mounting brackets 400 are fixed to the other side and top of each fixing frame 103. The two mounting brackets 400 located at the front end of the four mounting brackets 400 are externally fixed with… A laser emitter 500 and two other mounting brackets 400 are externally fixed with laser receivers 600. The interior of each of the two fixed frames 103 is provided with clamping components 300 for clamping the profile. The top of the adjustable crossbar 102 is provided with multiple U-shaped brackets 700. The exterior of the mounting rod 104 is provided with multiple locking devices 200 for fixing the U-shaped brackets 700. The top of the U-shaped brackets 700 and the side away from the mounting rod 104 are provided with detectors 900 for detecting the bending degree of the profile.

[0030] The detector 900 includes a fixed sleeve 901 fixed to the outside of the U-shaped bracket 700 and a movable sleeve 902 movably sleeved inside the fixed sleeve 901. A movable rod 903 is fixed at the center of the movable sleeve 902 and is movably sleeved inside the fixed sleeve 901. A spring 904 is movably sleeved on the outside of the movable rod 903. A light shield 905 is fixed at one end of the movable rod 903 located outside the fixed sleeve 901. A light-transmitting hole 905a is opened at the center of the light shield 905. A locking rod 906 is fixed at the bottom of the movable sleeve 902. The locking rod 906 is pushed by the spring 904 to fit against the surface of the profile. This allows multiple light-transmitting holes 905a to be misaligned when the profile deformation is too large, thus preventing the laser receiver 600 from receiving the light signal. This triggers the circuit to disconnect, preventing the indicator light 1100 from lighting up. This helps the staff quickly determine whether the profile curvature meets the standard and improves the detection efficiency.

[0031] Specifically, one of the side frames 101 has an indicator light 1100 mounted on its exterior.

[0032] The operation process of this embodiment is as follows: When it is necessary to inspect the profile, the profile is first inserted into the two fixed frames 103. At the same time, under the push of the spring 904, the clamp 906 is made to fit against the surface of the profile. Then, the laser emitter 500 is activated to emit a beam of light to the laser receiver 600. When the curvature of the profile exceeds the allowable range, the light-transmitting hole 905a of the light-shielding plate 905 located at the bending part of the profile is misaligned with the other light-transmitting holes 905a, so that the laser receiver 600 cannot receive the light signal, thereby triggering the circuit to disconnect and preventing the indicator light 1100 from lighting up. This helps the staff to quickly determine whether the curvature of the profile meets the standard and improves the inspection efficiency.

A fixing screw 102c is threaded onto one side of the slide plate 102a, and the fixing screw 102c abuts against the side of the sliding plate 102b. By sliding the sliding plate 102b and tightening the fixing screw 102c, it can be adapted to the inspection of profiles of different lengths.

[0035] The clamping assembly 300 includes a first adjusting screw 301 threaded onto the side of the fixed frame 103. One end of the first adjusting screw 301 located inside the fixed frame 103 is rotatably connected to a clamping plate 302, and the clamping plate 302 is slidably connected to the inside of the fixed frame 103. The other end of the first adjusting screw 301 is fixedly connected to a first adjusting knob 304. Two rollers 303 are rotatably connected to the side of the clamping plate 302 away from the first adjusting screw 301. By rotating the first adjusting knob 304, the position of the clamping plate 302 inside the fixed frame 103 can be adjusted, thereby enabling the inspection of profiles of different widths.

[0036] The mounting bracket 400 includes a vertical slot plate 401 fixedly connected to the outside of the fixed frame 103.

A mounting plate 404 is fixedly connected to the outside of the slider 403. The height of the laser emitter 500 and the laser receiver 600 can be adjusted by rotating the second adjustment knob 405 to drive the second screw 402 to rotate.

[0037] Specifically, the mounting rod 104 includes an I-shaped rod 104a and a U-shaped rod 104b that are respectively fixedly connected to one side of the two fixed frames 103, and the U-shaped rod 104b is movably inserted into the inside of the I-shaped rod 104a;
