Description

Technical Field

[0001] The utility model relates to the technical field of testing tools, in particular to a tool for size detection. Background Art

[0002] Sheet metal processing involves a comprehensive cold working process on thin metal sheets, including shearing, punching / cutting / combining, folding, riveting, splicing, and forming. It is widely used in industries such as aerospace, automotive, home appliances, and construction. Ensuring the dimensional accuracy of sheet metal stamping parts is crucial, as it directly impacts product assembly accuracy, functional performance, and the aesthetics of the finished product. Dimensional deviations can lead to problems such as improper mating between components, seal failure, and decreased mechanical properties, compromising product safety and customer satisfaction.

[0003] Therefore, rigorous dimensional testing of sheet metal stampings is an essential part of the production process. Currently, dimensional inspection of sheet metal stampings is often performed using a vernier caliper. However, a vernier caliper can only inspect the dimensions of one location at a time. When sheet metal stampings have unusual shapes, multiple measurements are required. Furthermore, the caliper's operation is complex, hindering inspection efficiency. Summary of the Invention

[0004] The purpose of the utility model is to overcome the problems in the prior art that sheet metal stamping parts are mostly inspected for size using vernier calipers, the process of inspecting special-shaped sheet metal stamping parts is lengthy, and the operation of the vernier caliper is complicated, which affects the inspection efficiency, and to provide a tool for size inspection.

[0005] The utility model provides a tool for size detection, comprising:

[0006] At least two slide rails, the slide rails are rotatably connected to each other, at least two of the slide rails rotate in the same plane, and the slide rails are provided with scales along their lengths;

[0007] a slider, the slider being slidably disposed on the slide rail and being movable along the length direction of the slide rail;

[0008] An angle gauge is connected to one of the slide rails. Rotating the slide rail can drive the angle gauge to rotate, and the angle gauge is used to measure the angle between any two of the slide rails.

[0009] The plurality of slide rails may be rotatably connected, and the ends of the slide rails may be connected to each other; the non-ends of the slide rails may be connected to each other; or the end and non-end regions of two adjacent slide rails may be connected.

[0010] The slide rails are rotatably connected, so the angle between any two slide rails can be changed. The slide rails provided with at least two rotatably connected slide rails can be adapted to special-shaped test pieces whose positioning points are not on a straight line, and the corresponding angle can be measured by an angle gauge. The slider is used to connect the positioning points of the test points, and the position of the slider is adapted to the position of the positioning points of the test piece. The slide rails are provided with scales along their length, so the scale corresponding to the positioning point can be judged by the position of the slider. The size of the test piece is determined according to the positioning point scales of different test pieces. The angle gauge can be driven to rotate by the rotation of the corresponding slide rail, which can reduce the time for adjusting the angle gauge and help improve measurement efficiency. Compared with the prior art, vernier calipers are often used to test test pieces. If a special-shaped test piece is encountered, multiple measurements are required. Not only is the detection efficiency low, but the required size may not be fully measured. The present device can be adapted to special-shaped test pieces and can obtain the corresponding size data at one time, which helps improve detection efficiency.

[0011] Preferably, the slider is detachably connected to the slide rail.

[0012] The slider is detachably connected to the slide rail so that the angle between two adjacent slide rails can be 0, thereby avoiding the situation where the two adjacent slide rails cannot overlap and affect the measurement.

[0013] Preferably, the slider is provided with a fixing hole, and the locking rod passes through the fixing hole to fix the slider, the fixing hole is provided with an internal thread, and the locking rod is provided with a corresponding external thread.

[0014] The locking rod is connected to the positioning point and passes through the fixing hole to fix the position of the slider on the slide rail, preventing the slide rail from moving during the test and affecting the test accuracy. The locking rod and the fixing hole are respectively provided with corresponding external and internal threads to facilitate the fixing of the slider.

[0015] Preferably, a boss is provided at the end of the locking rod.

[0016] Preferably, the locking rod is provided with a scale.

[0017] The locking rod is provided with a scale, and the corresponding height difference of the non-planar test piece can be calculated through the scale of the locking rod, thereby judging whether the height difference of the non-planar test piece is within a specified range.

[0018] Preferably, it comprises a first slide rail and a second slide rail, the first slide rail is provided with a gap along its length direction, and the second slide rail extends into the gap of the first slide rail.

[0019] The gap is along the length direction of the first slide rail, so the first slide rail can move along the length direction of the second slide rail, and the second slide rail can also move along the length direction of the first slide rail, which is suitable for more special-shaped test pieces.

[0020] Preferably, a positioning block is provided at the end of at least one of the slide rails.

[0021] The end of the slide rail is provided with a positioning hole to facilitate fixing the position of the test piece and improve the detection efficiency.

[0022] Preferably, the first slide rail and the second slide rail are connected by a screw.

[0023] The first slide rail and the second slide rail are connected by a screw rod, so the distance between the top surfaces of the first slide rail and the second slide rail can be adjusted, so as to be suitable for more special-shaped test pieces.

[0024] Preferably, the angle gauge is provided with:

[0025] A semicircular arc hole, with scales provided along the length direction of the semicircular arc hole;

[0026] a first connecting portion, the first connecting portion being slidably connected to one of the slide rails, and the position of the first connecting portion corresponding to the slide rail being adjustable;

[0027] A second connecting portion is slidably connected to the semicircular arc hole, and the second connecting portion is fixed to the other slide rail.

[0028] The first connecting portion is connected to either the first or second rail. When the first and second rails undergo non-rotational relative displacement, the first connecting portion can move along the corresponding rail to adjust the position of the angle gauge. The second connecting portion can move along the semicircular hole and is fixed to the other rail. When the angle between the two rails changes, the second connecting portion's position on the semicircular hole can be adjusted to measure the angle between the two rails. This arrangement facilitates quick reading of the corresponding angle value, improving measurement efficiency.

[0029] Preferably, the scale provided on the slide rail is replaced by a photoelectric sensor.

[0030] The photoelectric sensor can obtain the position of the slider on the slide rail, thereby obtaining the size of the workpiece to be measured.

[0031] Compared with the existing technology, the beneficial effects of the present invention are:

[0038] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, this should not be understood as limiting the scope of the present invention to the following embodiments, and all technologies implemented based on the present invention fall within the scope of the present invention.

[0039] Unless otherwise specified, in the description of the specific embodiments of the present invention, the terms indicating orientation or positional relationships such as "upper," "lower," "left," "right," "center," "inside," and "outside" are based on the orientation or positional relationships shown in the accompanying drawings, or are the orientation or positional relationships in which the inventive product / device / apparatus is typically placed when in use. These terms indicating orientation or positional relationships are merely for the purpose of facilitating the description of the present invention or simplifying the description of the specific embodiments to facilitate a quick understanding of the solutions by technicians. They do not indicate or imply that a particular device / component / element must have a specific orientation or be constructed and operated in a specific positional relationship, and therefore should not be construed as limiting the present invention.

[0040] In addition, if the terms "horizontal", "vertical", "overhanging", "parallel" and the like appear, it does not mean that the corresponding devices / components / elements are required to be absolutely horizontal or vertical or overhanging or parallel, but may be slightly tilted or have deviations. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly tilted. Alternatively, it can be simply understood that the corresponding devices / components / elements are set in directions such as "horizontal", "vertical", "overhanging", and "parallel", and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably an error / deviation within ±8%, more preferably an error / deviation within ±6%, more preferably an error / deviation within ±5%, and more preferably an error / deviation within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the present invention.

[0041] In addition, the expressions "first", "second", "third", etc. that appear in the terms are merely descriptions used to distinguish the same or similar components and should not be understood as emphasizing or implying the relative importance of specific components.

[0042] In addition, in the description of the embodiments of the present invention, "several," "plurality," and "a number" represent at least 2. It can also be 2, 3, 4, 5, 6, 7, 8, 9, or any other number, and can even be more than 9.

[0043] Furthermore, in the description of the technical solution of the present invention, unless otherwise expressly specified, defined, or limited, the terms "disposed," "installed," "connected," "connected," "provided with," "laid," and "arranged" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welded, riveted, bolted, threaded, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communicative; they may be direct, indirect via an intermediate medium, or internally connected between two components.

[0044] like Figures 1 to 4 As shown, a tool for size detection includes:

[0045] At least two slide rails, the slide rails are rotatably connected to each other, at least two of the slide rails rotate in the same plane, and the slide rails are provided with scales along their lengths;

[0046] a slider 4, the slider 4 being slidably disposed on the slide rail and being movable along the length direction of the slide rail;

[0047] An angle gauge 3 is connected to one of the slide rails. Rotating the slide rail can drive the angle gauge 3 to rotate, and the angle gauge 3 is used to measure the angle between any two of the slide rails.

[0048] In an optional embodiment, a first slide rail 1 and a second slide rail 2 are included. However, in actual use, the number of slide rails is determined according to actual conditions. The test piece 6 is a non-planar sheet metal stamping with a bend, and the positioning points are in the form of positioning holes. The selection of positioning holes is determined by the overall shape and size of the test piece 6 and is not described in detail in this embodiment. In this embodiment, the angle gauge 3 is disposed below the first slide rail 1 and the second slide rail 2.

[0049] In an optional embodiment, the slider 4 is detachably connected to the slide rail. If the slider 4 is detachably connected to the slide rail, when the height difference between two adjacent slide rails is less than the height of the slider 4 itself, the slider 4 can be removed, reducing the angle between the two adjacent slide rails to zero, thereby avoiding the situation where the two adjacent slide rails cannot overlap and affect the measurement. The slider 4 is provided with a fixing hole 401, through which the locking rod 5 passes and is connected to the positioning point.

[0050] In an optional embodiment, the locking rods 5 are provided with scales, and the corresponding height difference of the non-planar test piece 6 can be calculated through the scales of the locking rods 5, thereby determining whether the height difference of the non-planar test piece 6 is within a specified range.

[0051] In an optional embodiment, if Figure 1 As shown, the first rail 1 has a gap, into which the second rail 2 extends. This allows the top surface of the first rail 1 to be higher than that of the second rail 2, accommodating various non-planar DUTs. The gap between the first rail 1 and the second rail 2 is greater than the height of the second rail 2. The first rail 1 can move along the length of the second rail 2, and the second rail 2 can also move along the length of the first rail 1, allowing the position of the rotating shaft to be changed, accommodating a wider range of irregularly shaped DUTs.

[0052] The end of the first slide rail 1 is provided with a raised positioning block 101, such as Figure 4 When measuring the test piece 6, as shown in Figure 1As shown, one of the positioning holes of the test piece 6 is fixed to the positioning block 101, and the other two positioning holes, one is used to connect the first slide rail 1 and the second slide rail 2 at the same time, and the other is used to connect only the second slide rail 2. In the actual connection, the locking rod 5 passes through the positioning hole and the fixing hole 401 of the slider of the corresponding slide rail to complete the fixation of the slider. The fixing hole 401 is provided with an internal thread, and the locking rod 5 is provided with a corresponding external thread. Therefore, the distance between the first slide rail 1 and the second slide rail 2 can be adjusted, so that the distance between the top surfaces of the first slide rail 1 and the second slide rail 2 can be adjusted. In this embodiment, the rotating shaft of the first slide rail 1 and the second slide rail 2 is a locking rod 5 with an external thread.

[0053] The angle gauge 3 is provided with: a semicircular arc hole, with a scale provided along the length direction of the semicircular arc hole; a first connecting part, which is slidably connected to the second slide rail 2, and the position of the first connecting part on the second slide rail 2 can be adjusted; a second connecting part, which is slidably connected to the semicircular arc hole, and the second connecting part is fixed to the first slide rail 1. When the first slide rail 1 and the second slide rail 2 undergo non-rotational relative displacement (that is, the first slide rail 1 moves along the length direction of the second slide rail 2 or the second slide rail 2 moves along the length direction of the first slide rail 1), the first connecting part can move along the second slide rail 2 to adjust the position of the angle gauge 3. The second connecting part can move along the semicircular arc hole and is fixed to the other slide rail. When the angle between the two slide rails changes, the position of the second connecting part on the semicircular arc hole can be adjusted to measure the angle between the two slide rails. Such a configuration facilitates the rapid reading of the corresponding angle value, which helps to improve measurement efficiency.

[0054] In one or more embodiments, the scale provided on the slide rail can also be replaced by a photoelectric sensor.

[0055] In one or more embodiments, when the number of slide rails is greater than two, the multiple slide rails rotate in a single plane. The system comprises at least two rotating shafts. Both rotating shafts are capable of moving along the length direction of one of the slide rails to accommodate more irregular structures. The rotating shaft is a threaded locking rod 5, which can adjust the number of slide rails located on the same rotating shaft. The number of angle gauges is adapted to the number of rotating shafts. The angle gauge can be connected to the locking rod 5 using the center of the circle, or it can be connected in the same manner as the above-mentioned angle gauge.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
