Description

Technical Field

[0001] The utility model relates to the technical field of flaw detectors, in particular to a flaw detector for automobile parts. Background Technique

[0002] Flaw detectors are generally non-destructive. They are specially used in industrial departments such as shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation, and construction to inspect the quality of materials and parts processing and welding of hulls, pipelines, high-pressure vessels, boilers, airplanes, vehicles, and bridges, as well as the quality of various light metals, rubbers, ceramics, etc. The flaw detector can display the surface and internal defects of the parts and welds processed from the materials to evaluate the quality of the products, and show the position, shape, and size of the discontinuities. It can also detect extremely fine cracks, hair cracks, white spots, folds, inclusions, etc. on the surface of the materials, with high detection sensitivity, and can intuitively display the position, shape, and size of the defects.

[0003] When performing surface flaw detection on tubular objects, since there are many specifications of tubular parts, the flaw detector needs to fix the product before flaw detection. If not fixed, the flaw detector is prone to slipping and unstable fixation during the flaw detection of the product. Different specifications of products also require different fixing devices for fixation during flaw detection. Replacing the fixing device is both time-consuming and laborious, affecting the flaw detection efficiency of the product. In view of this, a flaw detector for automobile parts is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer toFigures 1-3 , a flaw detector for automotive parts in this embodiment includes a bottom plate 1. On one side of the upper end of the bottom plate 1, a side plate 2 is fixed. A linear module 7 is fixed on the side plate 2. The linear module is provided with an electric push rod 5 that can move left and right. The output end of the electric push rod 5 is fixed with a detection probe 6 for detecting parts. A limiting mechanism 3 is arranged on the bottom plate 1, and an adjusting mechanism 4 is arranged on the bottom plate 1.

[0021] The limiting mechanism 3 includes a fixing plate 301 and a first motor 303. Two fixing plates 301 that can move relatively or away from each other are arranged on the bottom plate 1. On one side of the fixing plate 301, two limiting blocks 302 are arranged. Inside the fixing plate 301, a rotatable gear 309 is vertically arranged. A first motor 303 for driving the gear 309 to rotate is fixed on the fixing plate 301, which is convenient for driving the gear 309 to rotate.

[0022] Two sliding rods 307 are fixed inside the fixing plate 301. A sliding sleeve 306 that can slide up and down is sleeved on the sliding rod 307. On one side of the sliding sleeve 306, a rack 308 that meshes with the gear 309 is fixed. On the side of the two sliding sleeves 306 away from each other, a support rod 305 is fixed. One end of the support rod 305 is fixed to one side of the limiting block 302.

[0023] In this device, by sleeving the tubular part on the two limiting blocks 302 and starting the first motor 303, the first motor 303 drives the gear 309 to rotate. The two sides of the gear 309 mesh with the rack 308. The rack 308 drives the sliding sleeve 306 to move. Then, through the two sliding sleeves 306 driving the movement away from each other, the limiting blocks 302 on the support rods 305 are driven to abut against the inner side of the tubular part, thereby performing limiting and fixing on it.

[0024] At the same time, a sliding groove 304 that is slidably matched with the support rod 305 is opened on one side of the fixing plate 301, which increases the stability of the up and down sliding of the support rod 305.

[0025] In addition, slopes are opened at both ends of the two limiting blocks 302 away from each other, so that the tubular part can be more easily sleeved on the limiting blocks 302. Anti-slip pads are fixed on the outer sides of the limiting blocks 302, which increases the friction between the limiting blocks 302 and the inner wall of the tubular part.

[0026] Please refer to Figure 2 , the limiting mechanism 3 in this embodiment includes a threaded rod 402 and a second motor 401. A rotatable threaded rod 402 is horizontally arranged inside the bottom plate 1. The second motor 401 is fixedly installed on the bottom plate 1. The output end of the second motor 401 is fixed with the threaded rod 402. Two sliders that can move relatively or away from each other are threadedly connected to the threaded rod 402. The upper ends of the sliders are fixed to the fixing plate 301.

[0027] The device adjusts the distance between the two fixing plates 301 by starting the second motor 401. The second motor 401 drives the threaded rod 402 to rotate, and the threaded rod 402 drives the fixing plates 301 on the two sliders to move relatively or away from each other, so as to limit and fix tubular parts of different lengths.

[0028] Wherein, the threads at both ends of the threaded rod 402 are opposite, so that the two sliders can move relatively or away from each other.

[0029] The working principle of the above embodiment is as follows:

[0030] When it is necessary to detect a tubular part, one end of the tubular part to be detected is placed on the fixing plate 301, so that the two limit blocks 302 on the tubular part are located inside the tubular part. Then, by starting the second motor 401 to drive the threaded rod 402 to rotate, the threaded rod 402 drives the fixing plates 301 on the two sliders to move relatively, so that the tubular part contacts the other fixing plate 301, and the slider on its upper part is also located inside the tubular part, thereby fixing both ends of the tubular part.

[0031] Then, by starting the first motor 303 to drive the gear 309 to rotate, the two sides of the gear 309 are engaged with the racks 308. The racks 308 drive the sliding sleeves 306 to move, and then drive the two sliding sleeves 306 to move away from each other, so as to drive the limit blocks 302 on the support rods 305 to abut against the inner side of the tubular part, thereby limiting and fixing it.

[0032] Subsequently, the linear module 7 drives the electric push rod 5 and the detection probe 6 to move back and forth to detect the tubular part.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
