Description

Technical Field

[0001] The utility model belongs to the technical field of sawing devices, in particular to a sawing device for processing terminal machine parts. Background Art

[0002] Terminal machine refers to a machine used for wire processing. During the processing operation, its parts need to be cut by a channel sawing device.

[0003] The sawing device generally consists of an output motor and a sawing blade connected to the output end of the output motor. In order to prevent the saw blade from heating up, becoming blunt, and generating smoke and dust, a medium needs to be sprayed on the saw blade during the sawing process. However, the existing spraying method is manual spraying, which poses a safety hazard. Utility Model Content

[0004] The utility model aims at solving the problems existing in the prior art and proposes the following technical solutions:

[0005] A sawing device for processing terminal machine parts, comprising a driving motor, an output shaft installed at the output end of the driving motor, and a serrated knife connected to the other end of the output shaft, a sleeve is arranged between the driving motor and the serrated knife, and the sleeve is coaxially arranged outside the output shaft and connected to the driving motor, an auger blade connected to the outside of the output shaft is arranged in the sleeve, and a first spraying port is opened on one end of the sleeve facing the serrated knife;

[0006] The auger blade is driven by the output shaft to rotate and force the medium to be sprayed toward the surface of the serrated blade through the first spraying port.

[0007] A spraying structure is arranged on one side of the serrated knife, which can automatically spray the medium to the serrated knife as the serrated knife rotates, replacing the traditional manual spraying method and reducing safety hazards.

[0008] As a preferred embodiment of the above technical solution, a plurality of groups of the first spraying ports are provided and are evenly distributed around the output shaft.

[0009] Since the plurality of groups of first spraying ports are evenly arranged around the output shaft, the medium can be sprayed circumferentially on the surface of the serrated blade.

[0010] As a preferred embodiment of the above technical solution, the output direction of the first spray port is toward the blade of the serrated knife.

[0011] Since the first spraying port is directed toward the blade of the serrated knife, the cutting point between the serrated knife and the terminal machine component can be directly cooled.

[0012] As a preferred embodiment of the above technical solution, a connecting plate is rotatably connected to the end surface of the sleeve on which the first spray outlet is provided, a second spray outlet corresponding to the first spray outlet is provided on the connecting plate, the second spray outlet and the first spray outlet form a spray channel, and the connecting plate can be driven by an external force to rotate relative to the sleeve to adjust the intercepting area of ​​the spray channel.

[0013] Since the first spray port and the second spray port overlap on the side projection surface, when the second spray port rotates, the overlapping area of ​​the first spray port and the second spray port changes, that is, the intercepting area of ​​the spray channel changes, so that the user can adjust it according to needs.

[0014] As a preferred embodiment of the above technical solution, one side of the driving motor is directly and / or indirectly connected to a medium storage box, and the medium storage box is connected to the inside of the sleeve through a connecting pipe.

[0015] Specifically, an input port connected to the connecting pipe is opened on one side of the sleeve. Since the medium storage box is connected to the sleeve, the medium storage box can be used as the medium source of the sleeve to ensure that the sleeve is continuously filled with medium, that is, the water pressure in the sleeve is not affected.

[0016] The beneficial effects of the utility model are:

[0017] In the present application, a spraying structure is provided on one side of the serrated knife, which can automatically spray the medium onto the serrated knife as the serrated knife rotates, replacing the traditional manual spraying method and reducing safety hazards.

In some other embodiments, a driving structure can be set on one side of the driving motor 1 to drive the driving motor 1 to translate or swing, so as to realize the movement of the serrated knife 11. This is well known to those skilled in the art and will not be elaborated in this application.

[0025] like Figure 2 As shown, a sleeve 2 is arranged between the driving motor 1 and the serrated knife 11, and the sleeve 2 is coaxially arranged outside the output shaft 6 and connected to the driving motor 1, and an auger blade 7 connected to the outside of the output shaft 6 is provided in the sleeve 2, and a first spray port 8 is provided on the end of the sleeve 2 facing the serrated knife 11; since the output shaft 6 is connected to the auger blade 7, the auger blade 7 can rotate with the output shaft 6 to form a material feed, and a medium is injected into the sleeve 2, and the medium is pushed by the rotation of the auger blade 7 and sprayed from the first spray port 8 toward the serrated knife 11, so that the medium can be sprayed onto the surface of the serrated knife 11 to achieve cooling; the first spray port 8 is provided with a plurality of groups, which are evenly arranged around the output shaft 6; since the plurality of groups of first spray ports 8 are evenly arranged around the output shaft 6, the medium can be sprayed circumferentially on the surface of the serrated knife 11; the output direction of the first spray port 8 is toward the blade of the serrated knife 11; since the first spray port 8 is directed toward the blade of the serrated knife 11, so the cutting point between the serrated knife 11 and the terminal machine component can be directly cooled, which can be achieved by changing the angle of the first spray port 8, or by some other means, and the present application does not make specific restrictions; the end face of the sleeve 2 on which the first spray port 8 is provided is rotatably connected with a connecting plate 9, and a second spray port 10 corresponding to the first spray port 8 is provided on the connecting plate 9, and the second spray port 10 and the first spray port 8 form a spray channel, and the connecting plate 9 is driven by an external force to rotate relative to the sleeve 2 to adjust the intercepting area of ​​the spray channel; since the first spray port 8 and the second spray port 10 overlap on the side projection surface, when the second spray port 10 rotates, the overlapping area of ​​the first spray port 8 and the second spray port 10 changes, that is, the intercepting area of ​​the spray channel changes, so that the user can adjust it independently according to needs.

[0026] like Figure 1 and Figure 2 As shown, one side of the drive motor 1 is directly and / or indirectly connected to a medium storage box 5, and the medium storage box 5 is connected to the sleeve 2 through a connecting pipe 4; specifically, an input port 3 connected to the connecting pipe 4 is opened on one side of the sleeve 2. Since the medium storage box 5 is connected to the sleeve 2, the medium storage box 5 can be used as a medium source for the sleeve 2 to ensure that the sleeve 2 is continuously filled with medium, that is, the water pressure in the sleeve 2 is not affected; in some embodiments, the medium storage box 5 can be directly installed on the drive motor 1, or it can be indirectly installed on one side of the drive motor 1 through supporting components such as brackets, and the present application does not make specific restrictions; in some embodiments, the medium storage box 5 can be arranged above the sleeve 2, and the liquid can continuously fill the sleeve 2 due to the influence of gravity, or a boosting component such as a water pump can be installed on the connecting pipe 4 to meet the water pressure requirement in the sleeve 2.
