[0002] When making shear specimens, the overlapping sections of various samples, such as aluminum sheets, stainless steel, CFRP, PC, ABS, or nylon, must be bonded together using adhesive. The bond width must be neither too wide nor too narrow, as this can affect the accuracy of the experimental data. Therefore, before bonding, each sample must be marked with auxiliary lines on both sides using a sharp object to calibrate the bonding position.

[0006] In the device for scribing auxiliary lines for bonding sheared samples of the present invention, the first scribing member is a quadrangular pyramid-shaped scribing member, and the second scribing member is a quadrangular pyramid-shaped scribing member.

[0007] In the device for scribing auxiliary lines for bonding sheared samples of the present invention, a sliding groove for the sheared sample to be inserted and slid is provided on the inner wall surface of the connecting portion, and the sliding groove is opposite to the gap.

[0008] In the device for scribing auxiliary lines for bonding sheared samples of the present invention, the width of the slide groove is greater than or equal to the thickness of the sheared sample.

[0009] In the device for scribing auxiliary lines for bonding sheared samples of the present invention, the top plate and the bottom plate are arranged parallel to each other.

[0010] The present invention provides a device for marking auxiliary lines for bonding sheared pieces, providing the following beneficial effects: When using the device, the end of the sheared piece is inserted into the gap until the end of the sheared piece contacts the inner wall of the connecting portion. The sheared piece is then translated until the first and second tips mark the required auxiliary lines on the top and bottom surfaces of the sheared piece, facilitating subsequent bonding of the sheared piece. The auxiliary lines marked by the marking device provide a uniform width across the bonding area, resulting in greater accuracy, improved marking efficiency, and improved ease of operation.

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 、 2 As shown, in the first embodiment of the shear sample bonding auxiliary line scoring device of the present invention, the scoring device 10 includes a handle 11, a connecting portion 12 fixed to the end of the handle 11, a top plate 13 fixed to the top of the connecting portion 12, a bottom plate 14 fixed to the bottom of the connecting portion 12, a first scoring member 15 fixed to the bottom surface of the top plate 13 pointing to the direction of the bottom plate 14, and a second scoring member 16 fixed to the top surface of the bottom plate 14 pointing to the direction of the top plate 13. The top end of the first scoring member 15 is provided with a first tip 17, and the bottom end of the second scoring member 16 is provided with a second tip 18. The first tip 17 and the second tip 18 are arranged opposite to each other, and a gap 19 is provided between the first tip 17 and the second tip 18 for the shear sample to pass through, and the spacing of the gap 19 is less than the thickness of the shear sample.

[0016] It can be understood that the distance between the first tip 17 and the second tip 18 and the inner wall surface of the connecting portion 12 is equal to the width of the bonding area of ​​the shear sample.

[0017] When using the device for marking auxiliary lines for bonding a sheared sample of the present invention, the end of the sheared sample is inserted into the gap 19 until the end face of the sheared sample abuts the inner wall of the connecting portion 12. The sheared sample is then translated until the first and second tips 17 and 18 mark the required auxiliary lines on the top and bottom surfaces of the sheared sample, facilitating subsequent bonding of the sheared sample. The auxiliary lines marked by the marking device 10 correspond to a uniform width of the bonding area, resulting in higher accuracy, higher marking efficiency, and greater ease of operation.

[0018] Specifically, the first scribing member 15 is a quadrangular pyramid scribing member, and the second scribing member 16 is a quadrangular pyramid scribing member.

[0019] In order to facilitate the guidance of the shearing sample when it moves, a sliding groove 20 for the shearing sample to slide into is provided on the inner wall surface of the connecting portion 12 , and the sliding groove 20 is opposite to the gap 19 .

[0020] Preferably, the width of the chute 20 is greater than or equal to the thickness of the shear sample.

[0021] When the shearing sample is aligned with the gap 19 and is ready to be inserted, the end of the shearing sample can be inserted into the slide groove 20 and the shearing sample can be slid along the slide groove 20 to achieve linear movement of the shearing sample between the first tip 17 and the second tip 18.

[0022] Preferably, the top plate 13 and the bottom plate 14 are arranged parallel to each other.

[0023] Furthermore, in this utility model, unless otherwise expressly specified or limited, terms such as "connected," "connected," and "stacked" should be interpreted broadly. For example, they may refer to fixed connections, detachable connections, or integration; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
