Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection tooling technology, specifically a welding product conformal inspection machine. Background Technology
[0002] There are many traditional methods for workpiece inspection, but they all have many drawbacks. For example, contact measurement is either difficult to implement or extremely inefficient for complex curves, curved surfaces, small features (such as small holes and sharp edges), thin-walled parts, or soft material workpieces, and may even damage the workpiece or the measuring tool itself. Measurement accuracy also depends heavily on the operator's skill and experience.
[0003] Template / gauge matching: This method requires the creation of high-precision physical templates or gauges for each specific workpiece shape. This approach is costly, time-consuming, and requires significant storage space. Furthermore, the templates themselves wear out and require periodic calibration and replacement. It cannot provide accurate quantitative data.
[0004] Coordinate measuring machines (CMMs): Although they are highly accurate and powerful, they are usually expensive, complex to operate, relatively slow to measure, have high environmental requirements, and are not efficient enough for large-scale online inspection. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a method that enables efficient, rapid, high-precision, and visual inspection of workpieces, significantly improving inspection efficiency and intuitiveness, and reducing costs and damage risks.
[0006] To achieve the above objectives, the present invention provides a welding product conformal inspection machine, comprising a vibrating plate, a stepped fixture, a conformal block, a first channel, a second channel, a guide groove, and a proximity switch sensor; the vibrating plate is disposed on a horizontal plane; the stepped fixture is disposed on the vibrating plate, and an arc-shaped groove is provided on the side wall of the stepped fixture, the arc-shaped groove being provided with a detection port; the welding product moves along the inner circumference of the stepped fixture, and unqualified welding products fall out along the detection port; the stepped fixture is provided with a straightening plate, the straightening plate being provided with a guide roller, the straightening plate being used to correct the direction of the welding product, causing the bottom plate of the welding product to move downwards; a straightening plate is provided on the side wall of the stepped fixture, the straightening plate being disposed on... Above the arc-shaped groove, the straightening plate is used to correct the orientation of the bottom plate of the welded product, so that the bottom plate of the welded product moves at a right angle to the side wall of the stepped fixture; the contour block is set on the stepped fixture, and the contour block is provided with a contour groove that conforms to the shape of the welded product; the first channel is set at the position corresponding to the detection port; the second channel has the same structure as the first channel; the guide groove is set on the stepped fixture, one end of the guide groove is connected to the contour block, and the other end is connected to the second channel, and qualified welded products fall out along the guide groove; the proximity switch sensor is set on the guide groove for counting qualified welded products.
[0007] Furthermore, the height of the arc-shaped groove is greater than the height of the base plate of the welded product, and the gap in the arc-shaped groove allows the base plate of the welded product to move out.
[0008] Furthermore, the height of the detection port is less than the lower limit height of the standard part of the welded product, and unqualified welded products fall out through the detection port along the first channel.
[0009] Furthermore, the height of the contour groove is less than or equal to the upper limit height of the standard part of the welded product, and the angular tolerance of the contour groove meets the angular tolerance of the standard part of the welded product.
[0010] Furthermore, the guide groove is provided with a straight groove, the height of which is greater than the height of the base plate of the welded product, and the gap in the straight groove allows the base plate of the welded product to move out.
[0011] Furthermore, both the first and second channels have a "Y" shaped structure.
[0012] Furthermore, the opening width of the first channel is greater than the width of the detection port, and the opening width of the first channel is greater than the length of the welded product.
[0013] Furthermore, the opening width of the second channel is greater than the width of the guide groove, and the opening width of the second channel is greater than the length of the welded product.
[0014] Furthermore, it also includes a workbench on which the vibrating plate is placed.
[0015] The beneficial effects of this utility model are as follows: This application eliminates the need for point-by-point measurement, enabling rapid inspection. For first-piece inspection, process inspection, or full inspection of mass-produced welded parts, its efficiency is far superior to coordinate measuring machines (CMMs) or manual tools; operators can directly observe whether the weld contour (such as reinforcement height, width, and weld leg size) is within the tolerance zone, achieving second-level qualification judgment.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0038] like Figure 1-7As shown, an embodiment of this utility model discloses a welding product contour inspection machine, including a vibratory plate 100, a stepped fixture 200, a contour block 300, a first channel 400, a second channel 500, a guide groove 600, and a proximity switch sensor 700; the vibratory plate 100 is disposed on a horizontal surface; the stepped fixture 200 is disposed on the vibratory plate 100, and an arc-shaped groove 210 is provided on the side wall of the stepped fixture 200, the arc-shaped groove 210 is provided with a detection port 220, the welding product moves along the inner circumferential surface of the stepped fixture 200, and the unqualified welding product 900 falls out along the detection port 220; the contour block 300 is disposed on the vibratory plate 100, the stepped fixture 200 is disposed on the second channel 500, the guide groove 600, and the proximity switch sensor 700. On the stepped jig 200, the contour block 300 is provided with a contour groove 310, which conforms to the shape of the welded product; the first channel 400 is set at the position corresponding to the detection port 220; the second channel 500 has the same structure as the first channel 400; the guide groove 600 is set on the stepped jig 200, one end of the guide groove 600 is connected to the contour block 300, and the other end is connected to the second channel 500. The qualified welded product 900 falls out along the guide groove 600 through the contour groove 310; the proximity switch sensor 700 is set on the guide groove 600 for counting the qualified welded products.
[0039] It should be noted that the standard part dimensions of the welded product 900 in this application are the upper limit (19.3+0.3=19.6mm) and the lower limit (19.3-0.3=19.0mm), and the product angle is (90°±2°); the step surface of the stepped jig 200 near the arc groove 210 is inclined inward, so that the base plate 910 of the welded product can be smoothly inserted into the arc groove 210.
[0040] In one embodiment, the height of the arc groove 210 is greater than the height of the base plate 910 of the welded product, and the gap in the arc groove 210 allows the base plate 910 of the welded product to move out.
[0041] In one embodiment, the height of the detection port 220 is less than the lower limit height of the standard part of the welded product, and the unqualified welded product 900 falls out through the detection port 220 along the first channel 400.
[0042] In one embodiment, the height of the contour groove 310 is less than or equal to the upper limit height of the standard part of the welded product, and the angular tolerance of the contour groove 310 meets the angular tolerance of the standard part of the welded product.
[0043] It should be noted that the testing method is as follows: the welded product is placed into the profiling block 300 for testing; the judgment rule is: if the welded product passes through the profiling block 300 smoothly, it is judged as a good product; if the welded product cannot pass through the profiling block 300, it is judged as a defective product.
[0044] In one embodiment, the guide groove 600 is provided with a straight groove 610, the height of which is greater than the height of the base plate 910 of the welded product, and the gap in the straight groove 610 allows the base plate 910 of the welded product to move out.
[0045] In one embodiment, both the first channel 400 and the second channel 500 are “Y” shaped structures.
[0046] In one embodiment, the opening width of the first channel 400 is greater than the width of the detection port 220, and the opening width of the first channel 400 is greater than the length of the welded product 900.
[0047] It should be noted that the inspection standard for inspection port 220 (lower limit size inspection) is: the lower limit of the total length of the product (19.3-0.3=19.0mm).
[0048] Detection method: through a 18.999mm limiting channel;
[0049] Judgment rule: If the welded product 900 falls from the first channel 400, it is judged as having a size lower than the tolerance limit (<19.0mm).
[0050] In one embodiment, the opening width of the second channel 500 is greater than the width of the guide groove 600, and the opening width of the second channel 500 is greater than the length of the welded product 900.
[0051] It should be noted that the testing standard for the 300mm contour block (maximum angle and total length) is as follows:
[0052] Testing items:
[0053] a) Angular tolerance (90°±2°);
[0054] b) Maximum size (19.3 + 0.3 = 19.6 mm);
[0055] C) Over-assembly;
[0056] Detection method: Using a contour guide device (contour block 300);
[0057] Judgment rule: Normal pass: Simultaneously meets the angle tolerance of 90°±2° and the size ≤19.6mm;
[0058] Jamming failure: Angle deviation <90° or >90° exceeding the standard, or size >19.6mm, or over-assembly.
[0059] In one embodiment, a worktable 800 is also included, on which the vibrating plate 100 is placed.
[0060] like Figure 10-12As shown, preferably, based on the above-mentioned welding product conformal inspection machine, the stepped fixture is provided with a correcting plate 230, and the correcting plate 230 is provided with a guide roller 231. The guide roller 231 is inclined towards the side wall of the stepped fixture. The correcting plate 230 is used to correct the direction of the welding product, so that the bottom plate 910 of the welding product moves downward. A correcting plate 240 is provided on the side wall of the stepped fixture. The correcting plate 240 is located above the arc groove. The correcting plate 240 is used to correct the direction of the bottom plate 910 of the welding product, so that the bottom plate 910 of the welding product moves at a right angle with the side wall of the stepped fixture.
[0061] Further, the above-mentioned inspection method of a welding product conformal inspection machine is as follows: the welding product moves forward automatically via the vibrating plate 100, the welding product's bottom plate 910 is oriented downwards via the straightening plate 230, and the welding product's head 920 is oriented upwards via the guide roller 231. The vibration of the vibrating plate 100 causes the bottom plate 910 of the welding product to be inserted into the arc-shaped groove. When the welding product moves to the straightening plate 240, the straightening plate 240 corrects the angle between the bottom plate 910 of the welding product and the side wall of the stepped fixture, so that it moves forward at a right angle. The height of the welding product slides and is detected against the stepped fixture 200 (upper and lower limits). Judgment rule: if the welding product successfully passes through the guide groove 600 (upper limit) and stops at the inspection port 220 (lower limit), it is judged as a good product. If the welding product cannot pass through the guide groove 600 (upper limit) or enter the inspection port 220 (lower limit), it is judged as a defective product.
