[0032] Embodiment:

[0033] As Figures 1-3As shown in the figure, a scratch tester for furniture boards of the present application includes a support column 100, a cross beam 200, a weight 300, a scratch assembly 400, a clamping disc 500, and a power source 600. The cross beam 200 is rotatably installed on the support column 100. The weight 300 is slidably installed on the cross beam 200. A scale 201 is provided on the cross beam 200 near the upper edge of the cross beam 200. The scratch assembly 400 is provided on the lower surface of the cross beam 200. The clamping disc 500 is provided below the scratch assembly 400. The clamping disc 500 is driven by the power source 600. The power source 600 is a motor, and the motor drives a turntable. The clamping disc 500 is installed on the turntable. Through the above structural design, the cross beam 200 is rotatably installed on the support column 100. The weight 300, the scale 201, and the scratch assembly 400 are provided on the cross beam 200. The clamping disc 500 driven by the power source 600 is provided below the scratch assembly 201. During the test, by moving the weight 300 to the correct position on the scale 201, the cross beam 200 obtains the correct load, and the upper end surface of the cross beam 200 is in a horizontal plane, so that the scratch assembly 400 can be in the correct working position, that is, only by moving the weight 300 to the correct position on the scale 201, which is not only convenient, but also greatly improves the precision and accuracy, and also ensures the observation result.

[0034] As a preferred mode of this embodiment, the support column 100 is fixed on a fixed platform 700, and a support leg 701 is fixedly provided at each of the four corners of the lower surface of the fixed platform 700.

[0035] Specifically, a counterweight portion 202 extends from the left end of the cross beam 200 toward the support column 100. The counterweight portion 202 is rotatably installed on the support column 100 through a spherical bearing 203. Since the counterweight portion 202 is rotatably installed on the support column 100 through the spherical bearing 203, when the weight 300 is moved to the corresponding position at the right end of the cross beam 200, the cross beam 200 is balanced under the action of the weight 300 at this time, that is, the upper end surface of the cross beam 200 is in a horizontal plane.

[0036] As a preferred mode of this embodiment, an embedding groove is provided at the upper part of the end of the cross beam 200 away from the counterweight portion 202, that is, at the upper part of the right end of the cross beam 200. A spirit level 204 is embedded in the embedding groove. The spirit level 204 is a bubble spirit level with a sensitivity of 0.01 mm / m, and is used to observe whether the cross beam 200 is in a horizontal state.

[0037] Specifically, the scratch component 400 includes a scratch member 401 and a handle portion 402. One end of the handle portion 402 is provided with a chuck 4021 for clamping the scratch member 401, and the other end of the handle portion 402 is provided with a connection head 4022. The connection head 4022 is provided with an external thread, and the connection head 4022 is threadedly connected to the cross beam 200. In this embodiment, the scratch member 401 is a diamond tool. The free end of the scratch member 401 is in a conical shape, with a cone angle of 90 degrees, and a rounded corner structure is adopted at the apex of the cone tip.

[0038] As a preferred embodiment of this embodiment, the scratch component 400 further includes a fastening sleeve 4023 sleeved on the outer periphery of the chuck 4021. One end of the fastening sleeve 4023 is bent inward into a closed shape. The inner side shape of the fastening sleeve 4023 is adapted to the outer side shape of the chuck 4021. Through the above structural design, the fastening sleeve 4023 enables the chuck 4021 to clamp the scratch member 401.

[0039] As a preferred embodiment of this embodiment, a through hole 4024 penetrates through the handle portion 402. The aperture of the through hole 4024 is small at the end close to the chuck 4021 and large at the end close to the connection head 4022. The scratch member 401 is placed in the through hole 4024, which further improves the clamping force of the chuck 4021 on the scratch member 401, making the chuck 4021 clamp more tightly.

[0040] As a preferred embodiment of this embodiment, the power source 600 is installed on a slider 601. The slider 601 is driven by a cylinder 602 to perform a linear reciprocating motion along a guide rail 603. The guide rail 603 is installed on a fixed platform 700, and the cylinder 602 is installed on a cylinder seat, and the cylinder seat is installed on the fixed platform 700. Before the test, the cylinder 602 is not working, and the slider 601 is located at a position close to the cylinder 602. First, the test piece is installed on the clamping disc 500, and then the cylinder 602 works, driving the slider 602 to move towards the support column 100, moving the clamping disc 500 below the scratch component 400, facilitating the scratch component 400 to perform a scratch test on the test piece.

[0041] In summary, through the above structural design, the present utility model solves the deficiencies existing in the prior art and has the characteristics of reasonable structure, high accuracy, good observation effect, etc.
