Problems solved by technology

Since the core block and the inner cavity of the waveguide cannot generate extrusion force, it needs to be pulled about 10 times repeatedly to remove the burrs in the inner cavity. At the same time, the sandpaper wrapped is easy to shift and damage, and the service life is short
In short, the production efficiency is low, the burrs are not completely removed, and the quality is difficult to guarantee

Embodiment 1

[0042] Such as Figure 1-4 As shown, a device for removing burrs in the cavity of a cracked waveguide includes a base 1, a deburring device 4 and an adjustment device, and the deburring device 4 is installed on the base 1 in a liftable manner through the adjustment device; the The deburring device 4 is provided with several burr collection grooves 41; wherein, the burr collection groove 41 is moved so that the burr 82 in the inner cavity of the crack waveguide 8 is cut and removed by the edge of the open end, and collected in the In the burr collection tank 41. Preferably, the base 1 is made of bakelite sticks, which can protect the inner wall of the inner cavity and avoid scratches.

[0043] The beneficial effect of this embodiment is: adjust the height of the thorn removing device 4 relative to the base 1 through the adjusting device, and the thorn removing device 4 descends relative to the base 1, reducing the height of the present invention, which can facilitate the present...

Embodiment 2

[0045] Such as Figure 1-4 As shown, a device for removing burrs in the cavity of a cracked waveguide includes a base 1, a deburring device 4 and an adjustment device, and the deburring device 4 is installed on the base 1 in a liftable manner through the adjustment device; the The deburring device 4 is provided with several burr collection grooves 41; wherein, the burr collection groove 41 is moved so that the burr 82 in the inner cavity of the crack waveguide 8 is cut and removed by the edge of the open end, and collected in the In the burr collection tank 41.

[0046] Preferably, the material of the base 1 is a Bakelite stick, which is an epoxy phenolic laminated glass cloth stick (3722-3725, 3841) in this embodiment, which can protect the inner wall of the inner cavity and avoid scratches; the material of the destab device 4 is Tool steel (45# steel, alloy steel, etc.) ensures the sharpness of the knife edge and improves the efficiency of scraping and removing burrs 82; th...

Embodiment 3

[0079] A method for removing burrs in a cracked waveguide cavity, using the above-mentioned device for removing burrs in a cracked waveguide cavity, characterized in that it includes the steps of:

[0080] S1: Squeeze the burr 82 in the crack 81 of the cracked waveguide 8 into the inner cavity;

[0081]S2: After the deburring device 4 is lowered relative to the base 1 by the adjusting device, the device for removing burrs in the cavity of the cracked waveguide enters the cracked waveguide 8 from the waveguide opening of the cracked waveguide 8 Under the action of the adjustment device, the side of the puncture removal device 4 away from the base 1 and the side of the base 1 away from the puncture removal device 4 are respectively tightly abutted against the crack waveguide 8 on the inner wall of the cavity;

[0082] The device for removing burrs in the inner cavity of the cracked waveguide moves back and forth in the inner cavity of the cracked waveguide 8; during the movemen...

Abstract

The invention relates to a device and a method for removing burrs in an inner cavity of a slit waveguide. The device comprise a base, a deburring device and an adjusting device, wherein the deburringdevice is arranged on the base in a lifting mode through the adjusting device; the deburring device is provided with a plurality of burr collecting grooves; the burr collecting groovesare moved to enable each groove edge at the opening end of each burr collecting groove to cut and remove burrs in the inner cavity of the slit waveguide; burrs are collected in the burr collecting grooves; the heightof the deburring device relative to the base is adjusted through the adjusting device, so that the burr collecting groove can conveniently enter the inner cavity of the slit waveguide; after enteringthe inner cavity, the adjusting device lifts the deburring device; the outer side of the deburring device and the outer side of the base are tightly abutted against the inner wall of the inner cavity; the deburring device moves in the inner cavity, the edge of each groove at the opening end of each burr collecting groove squeezes and cuts burrs on the same side of a crack in the moving directiontowards the inner cavity into the burr collecting grooves like a knife; and then the deburring device is reversely moved to remove burrs on the other side towards the inner cavity. According to the device and the method for removing burrs in the inner cavity of the slit waveguide, the function of removing and collecting all burrs is achieved.

Description

technical field [0001] The invention relates to the field of deburring devices, in particular to a device and method for removing burrs in the cavity of a cracked waveguide. Background technique [0002] As an important part of the radar antenna system, the crack processing of the cracked waveguide is processed by numerical control on the machining center, which realizes mechanization and automation. However, in terms of removing the burr remaining in the inner cavity after processing, it is still stuck in the core block wrapped with sandpaper and stuffed into the waveguide cavity, and the core block is twitched to perform piston movement to remove the burr in the waveguide cavity. Since the core block and the inner cavity of the waveguide cannot generate extrusion force, it needs to be pulled about 10 times repeatedly to remove the burrs in the inner cavity. At the same time, the sandpaper wrapped is easy to shift and damage, and the service life is short. In short, the pr...
