Description

Technical Field

[0001] The utility model relates to the technical field of plate limiting, in particular to a plate limiting mechanism. Background Art

[0002] Sheet metal is a flat rectangular building material sheet made into standard sizes and used in the construction industry to make wall, ceiling or floor components. It also refers to metal sheets that are forged, rolled or cast.

[0003] However, in the prior art, when existing operators use handheld cutting machines to cut plates, they often only use their arms to press and fix the plates. This fixing method is not stable and cannot properly limit the position of the plates, causing the plates to move during cutting, resulting in cutting deviation of the plates. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art: when the operator uses a handheld cutting machine to cut the plate, he often only presses and fixes the plate with his arms. This fixing method is not stable and cannot well limit the plate, which may cause the plate to move during cutting, causing the cutting of the plate to be offset.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a plate limiting mechanism, including a fixed pad, horizontal plates are provided at both ends of the upper surface of the fixed pad, and an air pump is fixed to one end of the horizontal plate, and a main air pipe is fixedly installed on one end of the air pump, a branch pipe is fixed through one side of the main air pipe, and a suction cup is fixed to one end of the branch pipe, and a solenoid valve is fixedly installed on one side of the branch pipe, the main air pipe, branch pipe and solenoid valve are embedded and connected in the horizontal plate, a pressure sensor is fixed on the surface of the horizontal plate on one side of the suction cup, and a control box is fixed to one side of the fixed pad.

[0006] As a preferred embodiment, a slide groove is provided on the upper surface of the fixed pad, and an electric telescopic rod is fixedly installed in the slide groove. One of the horizontal plates is fixedly connected to the fixed pad, and a slider is fixed to the other bottom end. The slider is slidably connected to the fixed pad, and the telescopic end of the electric telescopic rod is fixed to the slider.

[0007] As a preferred embodiment, support legs are fixedly mounted on the lower surfaces of the two horizontal plates.

[0008] As a preferred embodiment, a pulley is rotatably mounted on one end of the support leg.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] The utility model places the plate flat on two horizontal plates and covers the suction cup, then opens the solenoid valve and starts the air pump, causing the air pump to suck air into the main air pipe and the branch pipe, so that the plate is firmly adsorbed on the suction cup due to the negative air pressure and is fixed and limited, thereby ensuring its placement stability when it is subsequently cut.

[0011] When the plate does not cover all the suction cups on the horizontal plate, the pressure sensors in the plate-covered area are pressurized and transmit the pressure information to the control box. Each pressure sensor corresponds to the solenoid valve on its side. After receiving the pressure information from the pressure sensor and analyzing it, the control box will open the corresponding solenoid valve to ensure that only the branch pipes in the plate-covered area are unobstructed, effectively avoiding air leakage during the suction process of the main air pipe and branch pipes.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a plate limiting mechanism, including a fixed pad 1, the fixed pad 1 is fixed on the ground, and the two horizontal plates 2 are raised at the same time, so that the plates placed on the horizontal plate 2 will not be too close to the ground, effectively preventing the cutting wheel from easily touching the ground and causing damage to itself when the operator cuts the plate with a hand-held cutting machine. Horizontal plates 2 are provided at both ends of the upper surface of the fixed pad 1, and an air pump 5 is fixed to one end of the horizontal plate 2, and a main air pipe 6 is fixedly installed at one end of the air pump 5. A branch pipe 7 is fixed through one side of the main air pipe 6, and a suction cup 8 is fixed at one end of the branch pipe 7. A solenoid valve 9 is fixedly installed on one side of the branch pipe 7. The main air pipe 6, the branch pipe 7 and the solenoid valve 9 are embedded in the horizontal plate 2 and connected. The plate is placed flat on the two horizontal plates 2 and covered with the suction cup 8, and then the solenoid valve 9 is opened and the air is The pump 5 is started, and the air pump 5 sucks air into the main air pipe 6 and the branch pipe 7, so that the plate is firmly adsorbed on the suction cup 8 due to the negative air pressure, and is fixed and limited to ensure its stability when it is cut later. A pressure sensor 10 is fixed on the surface of the horizontal plate 2 on one side of the suction cup 8, and a control box 13 is fixed on one side of the fixed pad 1. When the plate does not completely cover the suction cup 8 on the horizontal plate 2, the pressure sensor 10 in the plate covering area is pressurized and transmits the pressure information to the control box 13, and each pressure sensor 10 corresponds to the solenoid valve 9 on its side. After receiving the pressure information of the pressure sensor 10 and analyzing it, the control box 13 will open the corresponding solenoid valve 9 to ensure that only the branch pipe 7 in the plate covering area is unobstructed, effectively avoiding air leakage during the suction of the main air pipe 6 and the branch pipe 7.

[0020] Example 2

[0021] like Figure 1-3 As shown, a slide groove 11 is provided on the upper surface of the fixed pad 1, and an electric telescopic rod 12 is fixedly installed in the slide groove 11. One of the horizontal plates 2 is fixedly connected to the fixed pad 1 and a slider is fixed to the other bottom end. The slider is slidably connected to the fixed pad 1, and the telescopic end of the electric telescopic rod 12 is fixed to the slider. When the plate cannot be placed on the two horizontal plates 2 at the same time to cover the suction cup 8 due to its own length and width, the movable horizontal plate 2 is controlled to move stably along the slide groove 11 with the help of the electric telescopic rod 12 to adjust the distance between the two horizontal plates 2. The width makes it adaptable to the plate, thereby solving the problem that the plate cannot be placed on two horizontal plates 2 at the same time to cover the suction cup 8 due to its own reasons. The lower surfaces of the two horizontal plates 2 are fixedly installed with support legs 3, and the support legs 3 play a supporting role for the middle suspended part of the horizontal plate 2. A pulley 4 is rotatably installed on one end of the support leg 3. When the movable horizontal plate 2 drives the support leg 3 to move together, with the help of the pulley 4, the support leg 3 can move more smoothly on the ground and reduce the noise generated by the friction between the support leg 3 and the ground.

[0022] Working principle:

[0023] like Figure 1-3 As shown, when the present invention is in use, the user first places the plate flat on the two horizontal plates 2. At this time, the plate will cover the suction cup 8 below it. At the same time, the pressure sensor 10 located on one side of the suction cup 8 will be compressed by the plate. The pressure sensor 10 will transmit the pressure information generated by the pressure to the control box 13. Since each pressure sensor 10 corresponds to the solenoid valve 9 on one side of it, the control box 13 will open the corresponding solenoid valve 9 after receiving the pressure information of the pressure sensor 10 and analyzing it. Then the user starts the air pump 5 to make the air pump 5 suck air into the main air pipe 6 and the branch pipe 7, so that the plate is firmly adsorbed on the suction cup 8 due to the negative air pressure to fix it in place.
