Description

Technical Field

[0001] The utility model relates to an aluminum alloy extrusion workpiece detection tool, in particular to a U-shaped groove height rapid detection tool. Background Art

[0002] In the field of aluminum alloy extrusion technology, with the widespread popularization and application of aluminum alloy products in automobiles, the size requirements for aluminum alloy products are getting higher and higher, and the proportion of U-shaped opening profiles is gradually increasing. Figure 1 As shown, for this kind of product with a U-shaped groove structure, detecting the depth of the U-shaped groove requires special tooling instead of a depth gauge to speed up the detection. Summary of the invention

[0003] In view of the shortcomings of the prior art, the utility model provides a U-shaped groove height rapid detection tool, which can quickly detect the depth of the U-shaped groove, improve the detection efficiency, and replace different sliders according to the height size of the U-shaped groove to be detected. It does not need to be fixed with screws, which is convenient for quick disassembly and assembly. The technical solution adopted by the utility model is:

[0004] A U-shaped groove height rapid detection tool, comprising a base and a slider, wherein a dovetail groove is arranged on the top of the base, the dovetail groove is arranged in the front-to-back direction, and one end thereof extends to the front side surface of the base, and a dovetail block is arranged on the bottom of the slider, and the dovetail block is slidably connected to the dovetail groove;

[0005] The top of the slider is configured as a reference surface, on which a first arc-shaped convex strip and a second arc-shaped convex strip having the same diameter are sequentially arranged, and the first arc-shaped convex strip and the second arc-shaped convex strip extend in the front-back direction respectively;

[0006] The width of the first arc-shaped convex strip is equal to the width of the second arc-shaped convex strip, and the height of the first arc-shaped convex strip is less than the height of the second arc-shaped convex strip, so that a detection step is formed between the first arc-shaped convex strip and the second arc-shaped convex strip.

[0007] Furthermore, slider steps are sunken on the left and right sides of the reference surface.

[0008] Furthermore, the distance between the rear end of the dovetail groove and the rear side surface of the base is not less than 10 mm.

[0009] Advantages of the utility model:

[0010] The bottom of the U-shaped groove is placed on the reference surface, and the U-shaped groove is pushed from the first arc-shaped convex strip to the second arc-shaped convex strip. The slide step is used to detect the depth of the U-shaped groove to improve the detection efficiency;

[0011] The dovetail block and dovetail groove form a mortise and tenon structure between the slider and the base, which enables quick replacement of the slider. The corresponding slider can be quickly replaced according to different U-groove heights without replacing the base.

[0012] When the U-shaped groove depth is detected, the pushing direction of the U-shaped groove is consistent with the direction in which the dovetail block of the slider slides into the dovetail groove, so that the slider does not need to be fixed with screws, which is convenient for quick disassembly and assembly.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Please see attached Figure 1-4 The utility model provides a U-shaped groove height rapid detection tool, including a base 100 and a slider 200, wherein a dovetail groove 110 is arranged on the top of the base 100, and the dovetail groove 110 is arranged along the front-to-back direction, and one end of the dovetail groove 110 extends to the front side of the base 100, and a dovetail block 240 is arranged at the bottom of the slider 200, and the dovetail block 240 is slidably connected to the dovetail groove 110; the top of the slider 200 is configured as a reference surface 210, and a first arc-shaped convex strip 220 and a second arc-shaped convex strip 230 of the same diameter are sequentially arranged on the reference surface 210, and the first arc-shaped convex strip 220 and the second arc-shaped convex strip 230 extend in the front-to-back direction respectively; wherein the width of the first arc-shaped convex strip 220 is equal to the width of the second arc-shaped convex strip 230, and the height of the first arc-shaped convex strip 220 is less than the height of the second arc-shaped convex strip 230, so that a detection step is formed between the first arc-shaped convex strip 220 and the second arc-shaped convex strip 230.

[0020] In a specific embodiment, the base 100 and the slider 200 are integrally formed structures, respectively made of H13 steel, quenched and heat treated after rough machining, and have good rigidity and corrosion resistance. When used, the corresponding slider 200 is selected according to the depth of the U-shaped groove, and the dovetail block 240 on the slider 200 is pushed into the dovetail groove 110 from front to back;

[0021] During testing, the U-shaped groove is placed upside down on the reference surface 210, so that the first arc-shaped protrusion 220 enters the groove of the U-shaped groove, and the U-shaped groove is pushed from front to back. If the U-shaped groove passes through the first arc-shaped protrusion 220 smoothly and rests against the slider step 250, it means that the depth of the U-shaped groove is within the tolerance range, indicating that the depth of the U-shaped groove is qualified.

[0022] If the following two situations occur, it means that the depth of the U-shaped groove is unqualified. In the first case, when the U-shaped groove is placed upside down on the reference surface 210, the bottom surface of the U-shaped groove does not fit the reference surface, indicating that the depth of the U-shaped groove is less than the height of the first arc-shaped convex strip, indicating that the depth of the U-shaped groove is insufficient; in the second case, when the U-shaped groove smoothly passes through the first arc-shaped convex strip 220 and abuts against the slider step 250, and slides to the second arc-shaped convex strip 230, it indicates that the depth of the U-shaped groove is too large; both of the above situations are that the depth of the U-shaped groove is unqualified and needs to be further processed or scrapped.

[0023] In one embodiment, in order to protect the left and right sides of the slider 200 and increase the stability of the base 100, the left and right sides of the base 100 extend upward to form a blocking bar 120, and the slider 200 is located between the two blocking bars 120. This embodiment does not limit the width of the blocking bar 120, but tries to make the height of the blocking bar 120 lower than the height of the reference surface 210 so as not to block the line of sight during the U-shaped groove detection.

[0024] In one embodiment, in order to further reduce the weight of the slider 200 without affecting the detection, slider steps 250 are provided on the slider 200 at the left and right sides of the reference surface 210 .

[0025] In one embodiment, in order to reserve a certain stop distance for the slider 200 while ensuring the connection strength between the slider 200 and the base 100, the distance between the rear end of the dovetail groove 110 and the rear side of the base 110 is not less than 10 mm.

[0026] In summary, the present application realizes rapid detection of the groove depth of the U-shaped groove, the tooling structure is stable and convenient for disassembly and assembly, and is suitable for detection of various groove depth sizes.

[0027] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
