Description

Technical Field

[0001] The present application relates to the technical field of automobile parts testing equipment, and in particular to a testing device. Background Art

[0002] Due to the complex manufacturing process and structure of door frames, there is an overlap gap between the door frame upper trim and the window frame. The size of this gap affects the door frame's appearance. Therefore, the upper trim must be punched at the overlap location to facilitate assembly. This gap has corresponding tolerance limits. A gap that is too large will result in poor appearance; a gap that is too small will interfere with the window frame, causing the trim to lift and subsequently cause leakage in the door frame. Therefore, dimensional inspection of this punched location is extremely important. Previous inspection methods were not simple, required too many measurement steps, and were inefficient.

[0025] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0026] Reference Figures 1 to 3The embodiment of the present application provides a detection device that can quickly measure the punching notch of a punched product, wherein the punching notch mentioned in the embodiment of the present application is a door frame trim 400, and a metal reinforcement core is generally provided in the door frame trim 400 to improve the structural strength.

[0027] Specifically, the detection device includes a first fixture 100, which includes a first detection part and a second detection part. The first detection part is used to locate the two sides and bottom surface of the punched product. If the punched product undergoes significant deformation after punching, the two sides and bottom surface of the punched product cannot fit the first detection part, and the end of the punched product cannot be positioned in the first detection part, which facilitates rapid detection of whether the punched part of the punched product is deformed.

[0028] The second detection portion includes a first reference surface 120 , and the first reference surface 120 is used to detect the size of the punching notch of the punched product.

[0029] Specifically, during testing, the portion of the punched product with the notch is positioned on the first testing section. The user manually slides along the first reference surface 120 to the top of the first testing section. If the wide side of the notch (the dimension of the side perpendicular to the punched product) is lower than the first reference surface 120, or if a protrusion is felt from the first reference surface 120, the wide side of the notch is unqualified. If the long side of the notch (the dimension along the direction in which the punched product extends) is smaller than the long side of the first reference surface 120 along the direction in which the punched product extends, the long side of the notch is unqualified. The second testing section allows for a more intuitive detection of whether the length and wide side of the notch meet the standards. The entire testing device has a simple structure, allows for convenient and rapid testing, and effectively improves testing efficiency.

[0030] The detection device also includes a second fixture 200, which is arranged on the first fixture 100. The second fixture 200 is used to position the end of the punched product so that the part of the punched product with the punching notch is positioned in the first detection part. The second fixture 200 and the first detection part work together to position the punched product of the product.

[0031] The inspection device also includes a measuring assembly 300, which is located in the second inspection section and is used to detect the protrusion of the punching notch of the punched product beyond the second inspection section. The measuring assembly 300 can intuitively measure the protrusion of the punching notch from the second inspection section, allowing adjustments to the punching equipment based on the collected dimensional data to improve the yield of subsequent punched products.

[0032] The above-mentioned detection device has a simple structure and is convenient for detection. The first detection part and the second detection part serve as the detection reference. The punched product positioned on the first detection part can be visually observed through the first detection part and the second detection part to see whether it meets the standards. Subsequently, if the size of the punched notch is too small so that the punched notch is higher than the second detection part, the measuring component 300 can also quickly collect the excess size data. A more intuitive detection can be performed without more complicated operations, effectively improving the detection efficiency.

[0033] In some embodiments, the first detection portion is a groove structure 110. A groove is formed on the first jig member 100 to match the shape of the punched product. The groove allows for quick positioning of the bottom and side surfaces of the punched product and also allows for quick detection of deformation at the punching location. In other embodiments, the groove can be formed by fixing other components to the surface of the first jig member.

[0034] In this embodiment, a second jig member 200 is positioned at the end of the groove. The end face of the second jig member 200 is shaped to match the end face of the punched product. The second jig member 200 is bolted to the first jig member 100 and seals the end of the groove. In actual production, to accommodate the different end face shapes of punched products, the second jig member 200 is configured accordingly, facilitating quick switching based on demand.

[0035] In some embodiments, the first reference surface 120 is adjacent to a groove wall of the groove, and a detection groove 130 is provided on a side of the first reference surface 120 away from the second fixture component 200 .

[0036] The top surface of one side of the groove of the first fixture 100 is milled flat to form a first reference surface 120. The distance between the first reference surface 120 and the bottom surface of the groove is determined according to the wide side dimension of the punching notch of a qualified punched product (the dimension of the side along the direction perpendicular to the punched product). When the qualified punched product is positioned in the groove, the punching notch of the qualified punched product is flush with the first reference surface 120. During inspection, you can slide your hand along the first reference surface 120 toward the groove. If you feel a bulge, it means that the punching notch of the punched product protrudes from the first reference surface 120.

[0037] Among them, the length of the first reference surface 120 along the extension direction of the groove is the same as the long side dimension of the punching notch of a qualified punched product, so that the long side dimension of the punching notch of the punched product (the dimension along the extension direction of the punched product) can be quickly and intuitively observed through the first reference surface 120 whether it meets the standard.

[0038] An inspection groove 130 is provided on a side of the first reference surface 120 away from the second fixture 200. Even if the wide side dimension (the dimension of the side perpendicular to the direction of the punched product) of the punched notch of the punched product does not meet the standard, the inspection groove 130 can still detect the long side dimension of the punched notch of the punched product. The width of the inspection groove 130 is also the allowable tolerance range of the long side dimension. If the wide side of the punched notch cannot be observed through the inspection groove 130, it means that the long side dimension of the punched notch of the punched product is unqualified.

[0039] In some embodiments, as Figure 2 As shown, the measuring component 300 includes a first detecting member 310, which can be moved above the first detecting portion. The end of the first detecting member 310 that can be moved above the first detecting portion has a measuring surface, which is inclined toward the first detecting portion. The side of the first detecting member 310 adjacent to the measuring surface is provided with a scale line.

[0040] The measuring surface is tilted toward the groove to avoid irregularities on the side of the punched product, making the measurement more accurate. By providing scale lines on the side of the first detection member 310 adjacent to the measuring surface, the size of the punched product's notch protruding from the second detection portion (i.e., the first reference surface 120) can be quickly read.

[0041] During measurement, the first detection member 310 is pushed toward the groove direction, and the measuring surface is brought into contact with the punched product. According to the contact position between the long side of the punched notch and the measuring surface, the scale line corresponding to the contact position is found, and the size of the punched notch of the punched product protruding from the second detection part (that is, the first reference surface 120) can be quickly and intuitively read.

[0042] In some embodiments, an extension direction of the scale line is perpendicular to an extension direction of the first detection portion, and a minimum scale unit of the scale line is millimeter.

[0043] In some embodiments, as Figure 2 and Figure 4 As shown, the measuring surface has multiple measuring steps 312 arranged in a stepwise manner. The width of each measuring step 312 corresponds to the minimum scale unit of a scale line. Each measuring step 312 corresponds to a minimum scale unit, making it easier to find the scale line corresponding to the measuring step 312 during measurement. The arrangement of measuring steps 312 makes observation more intuitive and reduces the risk of visual deviation affecting measurement results.

[0044] In some embodiments, the first fixture 100 has a limiting groove 121 for limiting the movement direction of the first detection member 310. The first detection member 310 is slidably disposed in the limiting groove 121, and the limiting groove 121 limits the sliding direction of the first detection member 310 to ensure that the measurement position of each punched product is the same.

[0045] The bottom surface of the limiting groove 121 is lower than the first reference surface 120, that is, when the first detection member 310 can move freely to the top of the groove and does not abut against the punched product, it means that the wide side size of the punching notch of the punched product does not meet the standard and the wide side size of the punching notch is lower than the standard value.

[0046] Alternatively, when the portion of the measuring surface lower than the first reference surface 120 abuts against the punched product, it also indicates that the wide side dimension of the punching notch of the punched product does not meet the standard, and the wide side dimension of the punching notch is lower than the standard value.

[0047] In some other embodiments, the measuring assembly 300 further includes a stopper 320 for preventing the first detecting member 310 from being separated from the stopper slot 121. This prevents the first detecting member 310 from being separated from the stopper slot 121 when the detecting device is not in use or when being transported.

[0048] Specifically, the limiting member 320 may be a stopper extending above the limiting groove 121 .

[0049] In some other embodiments, the limiting member 320 may also be a limiting column, which includes a pressing portion and a stud portion. The first detection member 310 has a waisted groove 311 for the stud portion to move, and the waisted groove 311 extends along the setting direction of the limiting groove 121. After the stud portion passes through the waisted groove 311, it is threadedly connected to the bottom of the limiting groove 121 to make the pressing portion close to the first detection member 310. The cross-sectional area of the pressing portion is greater than the width of the waisted groove 311, thereby limiting the first detection member 310 from being separated from the limiting groove 121. The length of the waisted groove 311 is the range of movement of the first detection member 310. When not performing detection, the first detection member 310 can move to a position above the groove away from the groove to avoid affecting the positioning of the punched product.

[0050] The limiting groove 121 is provided with a screw hole 122 adapted to the stud portion.

[0051] In some other embodiments, the detection device further includes a pre-tightening member, which is used to force the punched product into contact with the first detection portion. Specifically, the pre-tightening member is a magnet 140. In this embodiment, at least one magnet 140 is disposed on the bottom or side of the groove. This magnet 140 attracts the punched product into the groove, eliminating the need to manually support the end of the punched product that is not being tested during testing, freeing the inspector's hands.

[0052] Of course, in some other embodiments, the pre-tightening member may also be a pressing plate that can be flipped over the groove to press against the punched product.

[0053] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
