Description

Technical Field

[0001] The invention relates to the field of prefabricated component design, and more particularly to a prefabricated component design test bench and a use method thereof. Background Art

[0002] With the development of prefabricated buildings, the standardized production process of prefabricated components requires the inspection of the finished product size and specifications of prefabricated components. Conventional manual measurement has a large workload, high labor costs, low efficiency, and cannot effectively realize automated production. At the same time, manual measurement also has human errors and mistakes, so it cannot meet the current standardized production requirements.

[0003] The existing precast concrete components have the disadvantage of being inconvenient to cut during the design experiment process. Since the precast concrete components are composed of concrete, a large amount of dust will be generated during the cutting process. When this dust permeates inside the workers' workshop, it will affect the workers' respiratory health. In addition, since the precast concrete components are large, the position of the precast concrete components often needs to be adjusted during the cutting process, so manual adjustment is required, which not only consumes a lot of workers' physical strength, but also poses certain safety hazards. For this reason, we propose a precast component design test bench and its use method. Summary of the invention

[0018] S4, starting the dual-axis motor to drive the cutting blade to cut the preform, and at the same time, the cam drives the piston plate in the air pressure box to move up and down, so that air is sucked through the one-way air inlet valve and discharged through the one-way air outlet valve, so that air is sucked through the connecting pipe and the dust suction groove to absorb dust and debris during grinding, and the absorbed debris is discharged through the one-way air outlet valve and can be collected by the external box body;

At this time, the vent hole 2 48 cannot release air, so that the piston block 46 cannot move along the inside of the cavity 2 56, and then the shaft rod 28 fixed to the cam 3 45 cannot rotate, thereby ensuring that the roller 29 cannot rotate, making it difficult for the moving block 26 to slide along the moving groove 18, thereby ensuring the stability of the upper clamping plate 25 and the lower clamping plate 23; S2. Holding the carrying handle 53, pull the upper clamping plate 25 upwards, and then place the prefabricated part designed on the workbench 1 between the upper clamping plate 25 and the lower clamping plate 23.

[0046] S4, start the dual-axis motor 4, thereby driving the cutting blade 5 to cut the preform, and at the same time the cam 6 will drive the piston plate 10 in the air pressure box 8 to move up and down, so that air is sucked through the one-way air inlet valve 13 and discharged through the one-way air outlet valve 14, so that air is sucked through the connecting pipe 16 and the dust suction groove 15 to absorb dust and debris during grinding, and the absorbed debris will be discharged through the one-way air outlet valve 14 and can be collected by the external box body;

[0047] S5, start the second air pump 3303 to absorb the internal air pressure of the third cavity 50, so that the corresponding wedge-shaped tooth blocks 3306 shrink into the corresponding cavity 3 50, and control the number of the wedge-shaped tooth blocks 3306;

[0048] S6. Start the drive motor 32, and drive the gear 33 to rotate forward or reverse by controlling the drive motor 32 to rotate forward or reverse, thereby driving the rack 31 to move back and forth, thereby driving the preform between the upper clamping plate 25 and the lower clamping plate 23 to move back and forth, so that when cutting, there is no need to manually drag the preform to move, which is convenient for automatic cutting, and by adjusting the number of wedge-shaped tooth blocks 3306 on the outside of the gear 33, the meshing of the rack 31 and the gear 33 can be controlled, so that the forward and backward movement range of the preform can be controlled, which is convenient for adjusting the cutting according to needs and is more convenient to use.

[0049] The working principle of the device is as follows: holding the handle 54, driving the corresponding vertical rod 24 to rotate, so that the cam 2 37 rotates, thereby pushing the shielding strip 39 to move through the cam 2 37, so that the vent hole 1 43 moves into the movable groove 42, thereby ensuring that the movable groove 42 is sealed, and at this time, the vent hole 2 48 cannot release air, so that the piston block 46 cannot move along the inside of the cavity 2 56, and then the shaft rod 28 fixed to the cam 3 45 cannot rotate, thereby ensuring that the roller 29 cannot rotate, making it difficult for the moving block 26 to slide along the moving groove 18, ensuring the stability of the upper clamping plate 25 and the lower clamping plate 23, holding the carrying handle 53, pulling the upper clamping plate 25 upwards, and then placing the workbench 1 on the workbench 1 The designed prefabricated part is placed between the upper clamping plate 25 and the lower clamping plate 23. Under the action of the spring 35, the upper clamping plate 25 and the lower clamping plate 23 can stably clamp the prefabricated part. The air pump 17 is started to evacuate or inflate the air pressure telescopic tube 7, thereby driving the air pressure telescopic tube 7 to lengthen or contract, thereby pushing the U-shaped mounting frame 3 to rise or fall, driving the cutting blade 5 to adjust the position with the prefabricated part, and facilitating the cutting of prefabricated parts with different thicknesses. The air pump 17 evacuates or inflate the air pressure telescopic tube 7, and inflate or inflate the air pressure telescopic tube 2 12, thereby adjusting the extension or contraction of the air pressure telescopic tube 2 12, ensuring that the cam 6 and the air pressure telescopic tube 12 are aligned. The shrink tube 12 is in contact with each other, and the rotation of the cam 6 is ensured to drive the piston plate 10 to keep its range of motion unchanged, so as to ensure that when the cam 6 pushes the piston plate 10 to move, the air pressure box 8 can be normally ventilated, and the debris during cutting can be absorbed and discharged. The dual-axis motor 4 is started, thereby driving the cutting blade 5 to cut the preform. At the same time, the cam 6 will drive the piston plate 10 in the air pressure box 8 to move up and down, so as to inhale air through the one-way air inlet valve 13 and discharge air through the one-way air outlet valve 14, so that air is inhaled through the connecting pipe 16 and the dust suction groove 15 to absorb dust and debris during grinding. The absorbed debris will be discharged through the one-way air outlet valve 14 and can be collected by the external box body. The air pump 2 3303 is started to absorb air. The air pressure inside cavity three 50 causes the corresponding wedge-shaped tooth blocks 3306 to shrink into the corresponding cavity three 50, and the number of wedge-shaped tooth blocks 3306 is controlled, and the drive motor 32 is started. By controlling the drive motor 32 to rotate forward or reverse, the gear 33 is driven to rotate forward or reverse, thereby driving the rack 31 to move back and forth, thereby driving the preform between the upper clamping plate 25 and the lower clamping plate 23 to move back and forth, so that when cutting, there is no need to manually drag the preform to move, which is convenient for automatic cutting, and by adjusting the number of wedge-shaped tooth blocks 3306 on the outside of the gear 33, the meshing of the rack 31 and the gear 33 is controlled, so that the forward and backward movement amplitude of the preform can be controlled, which is convenient for adjusting the cutting according to needs and is more convenient to use.
