Then the servo motor is started, so that the servo motor drives the forward and reverse ball screws to rotate, thereby driving the two movable seats to move toward each other until the outer side walls of the movable rods on both sides abut against the opposite side walls of the building materials, thereby limiting the initial position of the building materials.

[0018] 2. In the utility model, the second electric push rod is started to move upward, thereby driving the storage box and the suction cup to move upward. During this process, the user needs to press the building material until the top of the storage box is against the bottom of the building material. At this time, the suction cup will fit tightly with the building material under the action of the connecting spring.

[0030] The second positioning member has the same structure as the first positioning member, and the two are symmetrically arranged with respect to the mid-vertical plane of the forward and reverse ball screw 403;

[0031] The positioning mechanism also includes a rectangular hole opened on the outer wall of the positioning box 401, wherein the forward and reverse ball screw 403 is located inside the positioning box 401, and one end of the limit block 405 connected to the limit frame 406 extends to the outer surface of the positioning box 401 through the rectangular hole, and the longitudinal section of the rectangular hole matches the longitudinal section of the limit block 405. Through the cooperation between the limit block 405 and the rectangular hole, the movable seat 404 moves more smoothly.

[0032] By placing the building materials on the top of the workbench 1 and making the side walls of the building materials fit with the outer walls of the positioning box 401, and then starting the servo motor 402, the servo motor 402 drives the forward and reverse ball screw 403 to rotate, thereby driving the two movable seats 404 to move towards each other until the outer walls of the movable rods 407 on both sides abut against the opposite side walls of the building materials, thereby limiting the initial position of the building materials.

[0033] Embodiment 2: Figure 1-5 As shown, a sample preparation device for building material testing includes a workbench 1, a support frame 2 fixedly connected to the top of the workbench 1, and a cutting mechanism fixedly connected to the outer side wall of the workbench 1, and also includes a positioning mechanism fixedly connected to the top of the workbench 1, and a transmission mechanism arranged on the top of the workbench 1;

[0034] The positioning mechanism includes a positioning box 401 fixedly connected to the top of the workbench 1, a servo motor 402 fixedly connected to the outer wall of the positioning box 401, and a forward and reverse ball screw 403 fixedly connected to the output end of the servo motor 402 for driving the first positioning member and the second positioning member;

[0035] The transmission mechanism includes an electric lifter 501 fixedly connected to the bottom of the support frame 2, and a fixing plate 502 fixedly connected to the output end of the electric lifter 501 for fixing the building materials.

The cutting blade 304 is driven by the horizontal push rod 301 to move along the width direction of the workbench 1, and is driven by the driving motor 303 to rotate, thereby cutting the building materials.

[0040] When the building materials are positioned, the second electric push rod 505 is started to move upward, thereby driving the storage box 506 and the suction cup 509 to move upward. During this process, the user needs to press the building materials until the top of the storage box 506 is against the bottom of the building materials. At this time, the suction cup 509 will fit tightly with the building materials under the action of the connecting spring 507. Then, the air pump 5010 is started to extract the gas inside the suction cup 509, so that the inside of the suction cup 509 presents a negative pressure, thereby fixing the building materials and the suction cup 509. Then, the building materials are released, and the suction cup 509 and the building materials are driven to move by the first electric push rod 503, so that the distance that the building materials protrude from the workbench 1 can be controlled.

[0041] When the position of the building material is adjusted, the electric lift 501 is driven to drive the fixing plate 502 downward until the fixing plate 502 abuts against the building material, thereby fixing the building material. Then, the cutting blade 304 is driven to rotate by the driving motor 303, and the horizontal push rod 301 drives the mounting frame 302 to move, thereby realizing the cutting and sampling of the building material.
