Abstract
Description
Technical Field
[0001] This utility model relates to the field of measurement technology, and in particular to a measuring fixture. Background Technology
[0002] Resource boards and aging boards work together to perform aging tests on electronic devices such as chips. Different chips require different resource boards. Therefore, when storing a large number of resource boards, it is necessary to classify them by size in order to make reasonable use of storage space and improve storage efficiency.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0037] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.
[0038] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.
[0039] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values not using relative terms should also be disclosed as specific values with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.
[0040] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.
[0041] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element.

[0042] like Figures 1 to 3 As shown, this embodiment provides a measuring fixture for measuring the length, width, and height dimensions of circuit boards such as resource boards. The measuring fixture includes a base 100, a first measuring element 210, a second measuring element 220, and a height measuring assembly 300. The base 100 supports the workpiece to be measured. The first measuring element 210 is disposed on the base 100 and extends along a first direction, and has a first scale. The second measuring element 220 is disposed on the base 100 and extends along a second direction perpendicular to the first direction, and has a second scale. The height measuring assembly 300 includes a third measuring element 310 and an abutment element 320. The third measuring element 310 extends along a third direction and has a third scale, which is perpendicular to both the first and second directions. The abutment element 320 reciprocates relative to the base 100 along the third direction to abut against the workpiece to be measured located on the base 100.
[0043] The first direction is the length direction, the second direction is the width direction, and the third direction is the height direction.
[0044] With the above setup, when the workpiece to be measured is placed on the base 100, the length and width of the workpiece can be directly measured through the first measuring element 210 and the second measuring element 220. Then, the abutment 320 abuts against the end of the workpiece away from the base 100, and the height of the abutment 320 can be read through the third measuring element 310, thereby obtaining the height of the workpiece. The entire measurement process is simple and quick, which helps to reduce measurement time and improve measurement efficiency. At the same time, since a measuring tape is not used, the risk of scratching the measurer is reduced.
[0045] The first measuring element 210 has a first limiting surface 211, which is perpendicular to the base 100 and is configured to abut against one end of the workpiece in the width direction so that the workpiece will not move along the width direction during measurement, and the abutment against the first limiting surface 211 makes it easier to observe the length dimension of the workpiece.
[0046] The second measuring element 220 has a second limiting surface 221, which is perpendicular to the base 100 and is configured to abut against one end of the workpiece in the length direction so that the workpiece will not move along the length direction during measurement, and the width dimension of the workpiece is more easily observed when it abuts against the second limiting surface 221.
[0047] When the workpiece under test is a resource board, the circuit board has several components of different heights. To accurately determine the true height of the resource board, in some embodiments, the abutment 320 is plate-shaped, parallel to the workpiece under test, and has a contact surface corresponding to at least a portion of the workpiece under test. This facilitates contact with the tallest component on the resource board, thus conforming to the true height of the resource board. Specifically, the contact surface is located in the middle of the workpiece under test and covers at least 1 / 3 of the area of the workpiece when placed horizontally. In some embodiments, the contact surface completely covers the workpiece under test.
[0048] To facilitate reading, in some embodiments, the base 100 has a bearing surface for supporting the workpiece to be measured. The first measuring element 210 has a first measuring surface 212, parallel to the bearing surface, and a first scale is located on the first measuring surface 212. The second measuring element 220 has a second measuring surface 222, parallel to the bearing surface, and a second scale is located on the second measuring surface 222. In use, the operator can directly see the first scale on the first measuring surface 212 and the second scale on the second measuring surface 222 from above the workpiece.
[0049] To facilitate reading the third scale on the third measuring element 310, in some embodiments, the measuring fixture further includes a reading element 390. The reading element 390 is a block structure, fixed to the abutment element 320, and moves synchronously with it. The reading elements 390 are arranged side-by-side on one side of the third measuring element 310. For easier reading, the lower end of the reading element 390 is flush with the bottom surface of the abutment element 320. During reading, the lower end of the reading element 390 serves as a reference surface. Aligning the reference surface with a certain scale line of the third scale allows for reading the value corresponding to that scale line. When the reference surface is between two adjacent scale lines, the value corresponding to the closer scale line is read. The values of the third scale gradually increase from bottom to top.
[0050] In some embodiments, the height measuring component 300 includes a slide rail 330 and a slider 340. The slide rail 330 is disposed on the base 100 and extends along a third direction. The slider 340 is slidably disposed on the slide rail 330 along the third direction. An abutment 320 is disposed on the slider 340 and moves synchronously with the slider 340 to abut against the workpiece to be measured located on the base 100. In use, the slider 340 or the abutment 320 is pulled upward, and then the workpiece to be measured is placed on the base 100. Finally, the abutment 320 is moved downward until it reaches the top of the workpiece to be measured and stops moving. At this point, a reading can be taken. The above configuration ensures the standardized movement of the abutment 320, improving testing efficiency and accuracy.
[0051] To facilitate the placement and removal of the workpiece to be tested, in some embodiments, the abutment 320 is rotatably connected to the slide rail 330 via a slider 340, allowing the abutment 320 to rotate relative to the base 100 about the axis of the slide rail 330. With this structure, the abutment 320 can still rotate about the slide rail 330 after rising, ensuring the base 100 is not obstructed and facilitating the placement or removal of the workpiece from the base 100. Specifically, the slide rail 330 is a cylindrical rod structure, and the slider 340 has a sliding channel through which the slide rail 330 passes.
[0052] Furthermore, the height measuring component 300 also includes a linear bearing 370, which is disposed between the slide rail 330 and the slider 340 to improve the smoothness of movement and rotation of the slider 340 relative to the slide rail 330, thereby improving the operating feel and user experience.
[0053] To improve ease of operation, the height measuring assembly 300 also includes a handle 360, which is disposed on the slider 340. Specifically, the handle 360 includes a grip rod 361 and a vertical rod 362. One end of the vertical rod 362 is connected to the slider 340, and the grip rod 361 is disposed at the end of the vertical rod 362 away from the slider 340. The grip rod 361 is designed for the operator to hold, facilitating the lifting and lowering of the slider 340. The grip rod 361 is an arc-shaped rod that curves towards the vertical rod 362, improving grip comfort. In this embodiment, the grip rod 361 and the vertical rod 362 are welded together, and the lower end of the vertical rod 362 is screwed into a screw hole in the slider 340.
[0054] Since the slider 340 needs to rotate relative to the slide rail 330, in some embodiments, the handle 360 is connected to the slider 340 and located on the side of the axis of the slide rail 330, so as to apply a lateral force to drive the slider 340 to rotate relative to the slide rail 330, thereby improving the convenience and operability of operation.
[0055] In some embodiments, the height measuring assembly 300 further includes an elastic element 380 disposed between the slider 340 and the base 100. The elastic element 380 applies an elastic force to the slider 340 to move the slider 340 away from the base 100. This arrangement allows for measurement by pressing down the handle 360, compressing the elastic element 380, causing the contact surface of the abutment 320 to contact the workpiece to be measured and read directly. When the handle is released, the abutment 320 automatically rises under the elastic force of the elastic element 380, and then a lateral force is applied to the handle 360, driving the abutment 320 to rotate to the side of the base 100 for easy replacement of the workpiece to be measured. Compared to applying an upward force to pull up the abutment 320, pressing down the handle 360 to move the abutment 320 downward is more in line with operating habits and saves physical strength; in addition, the workpiece to be tested is not subjected to pressure when there is no external force, which improves safety; finally, when there is no external force, the abutment 320 remains in a high position, which makes it easy to pick up and put down the workpiece to be tested with both hands.
[0056] The base 100 has a bearing surface for supporting the workpiece to be measured. The height measuring component 300 includes a connecting rod 350, which is connected to a sliding member 340. An abutment member 320 is connected to the connecting rod 350. Along a third direction, the outline of the projection of the connecting rod 350 lies on the bearing surface, and the outline of the projection of the abutment member 320 lies within the bearing surface. In this embodiment, the abutment member 320 can be a flat plate structure. The connecting rod 350 is screwed to the abutment member 320. The connecting rod 350 is also screwed to the sliding member 340. Connecting the abutment member 320 and the sliding member 340 with the connecting rod 350 improves the convenience of connection, simplifies the structure of the abutment member 320, and reduces production difficulty.
[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
