Specific implementation

[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Please refer to Figures 1-4 , the utility model provides an embodiment: a chain production is with trepanning device, including collecting bin 1, chain limiting plate 6 and mounting plate 7, and the top of both ends of collecting bin 1 is installed with fixed plate 4, and the top of fixed plate 4 is installed with mounting plate 7, and the middle position of the top of mounting plate 7 is installed with electric cylinder 8, and the model of electric cylinder 8 can be J64RT2UNIVER, and the output end of electric cylinder 8 passes through mounting plate 7, and the output end of electric cylinder 8 is installed with punch head 9, and the both ends of the top of collecting bin 1 are provided with sliding groove 17, and the inside of sliding groove 17 is slidably installed with sliding block 18, and the top of sliding block 18 is installed with chain limiting plate 6, and the bottom of one end of collecting bin 1 is installed with air suction pump 12, and the model of air suction pump 12 can be VCH1028, and the bottom of one end of collecting bin 1 away from air suction pump 12 is installed with control panel 2, and the output end of control panel 2 is electrically connected with the input end of electric cylinder 8 and air suction pump 12 through wire respectively, and one side of collecting bin 1 is installed with bin door 14, and the outside of bin door 14 is installed with handle, after use, opening bin door 14, the dust and chippings collected in the inside of collecting bin 1 can be handled.

[0024] As Figures 1-2As shown, a through hole 20 is provided at the middle position of the top of the collection chamber 1, and a screen 3 is installed inside the collection chamber 1. An air extraction pipe 13 extending into the collection chamber 1 is installed at the input end of the air pump 12. During the opening process, the air pump 12 extracts the gas inside the collection chamber 1 through the air extraction pipe 13, so that the debris and dust falling from the chain enter the collection chamber 1 through the through hole 20. The debris and dust in the gas can be filtered by the screen 3, so that the debris and dust can be collected inside the collection chamber 1 for unified treatment of the debris and dust.

[0025] like Figures 1-4 As shown, bearings 16 are evenly installed on the top of the chain limiting plate 6 near the electric cylinder 8, and rotating rods 19 are installed inside the bearings 16. Limiting rollers 15 are installed on the outer side of the rotating rods 19. Telescopic springs 11 are installed on the bottom of the chain limiting plate 6 away from the electric cylinder 8, and the ends of the telescopic springs 11 away from the chain limiting plate 6 are connected to the fixing plate 4. Adjusting screw holes 10 are provided inside the fixing plate 4, and adjusting screws 5 are threaded into the adjusting screw holes 10. The elasticity of the telescopic spring 11 pulls the chain limiting plate 6, allowing the chain limiting plate 6 to fit tightly against the adjusting screw 5. The operator can rotate the adjusting screw 5, causing it to move through the adjusting screw hole 10 via the thread. The adjusting screw 5 pushes the chain limiting plate 6 to slide, thus adjusting the position of the chain limiting plate 6. By adjusting the positions of the two sets of chain limiting plates 6, the limiting roller 15 can fit against chains of different widths, making the device suitable for chains of different widths.

[0026] Working principle:

[0027] When in use, the device is connected to the power supply, and the operator can pass the chain between the two sets of chain limit plates 6 and pass the chain under the punch head 9;

[0028] At this time, the elastic action of the telescopic spring 11 pulls the chain limiting plate 6, which makes the chain limiting plate 6 fit tightly with the adjusting screw 5. The operator can rotate the adjusting screw 5 clockwise, so that the adjusting screw 5 moves inside the adjusting screw hole 10 through the thread. The adjusting screw 5 pushes the chain limiting plate 6 to slide, and the position of the chain limiting plate 6 can be adjusted. By adjusting the position of the two sets of chain limiting plates 6, the limiting roller 15 can fit with chains of different widths.

[0029] The chain is limited by the limiting roller 15 to prevent the chain from moving laterally during the hole-making process, ensuring that the punch head 9 can accurately punch onto the chain. When the chain is pulled by external traction equipment, the limiting roller 15 can rotate under force, so that the limiting roller 15 will not affect the movement of the chain.

[0030] When the hole is opened, the chain can be moved by external traction equipment, and the staff can start the electric cylinder 8 through the control panel 2, so that the electric cylinder 8 pushes the stamping head 9 to move downward, that is, the chain can be opened through the stamping head 9;

[0031] During the hole opening process, the staff can start the air suction pump 12 through the control panel 2, the air suction pump 12 sucks out the gas in the collecting bin 1 through the air suction pipe 13, so that the debris and dust falling on the chain enter the inside of the collecting bin 1 through the through hole 20, and the debris and dust in the gas can be filtered through the screen 3, so that the debris and dust can be collected in the collecting bin 1, and the debris and dust can be conveniently uniformly treated.

[0032] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
