Description

Technical Field

[0001] The utility model relates to the technical field of hardware corner rounding machines, in particular to a corner rounding machine for hardware processing. Background Art

[0002] In mechanical processing technology, the working principle of the corner grinder is similar to that of existing machine tools. The hardware is fixed in the clamping jaws, and a corner grinding tool is provided on one side of the clamping jaws. The linear drive device can perform a lateral feeding operation on the tool connecting frame and the corner grinding tool. At the same time, the rotating shaft on the high torque motor drives the clamping jaws and the hardware to rotate, so that the corner grinding tool can perform a rotational corner grinding operation on the hardware.

[0003] Among them, the existing angle grinding tools are generally fixed on the linear drive device by connecting parts such as bolts and nuts. The user can replace the angle grinding tool through auxiliary parts such as tools. However, this method makes the replacement of the angle grinding tool more complicated. The corresponding tools must be possessed for disassembly, and the disassembly speed is slow, which is not conducive to rapid replacement, thereby reducing the working efficiency of the overall angle grinding tool. Therefore, in order to solve the above problems, we propose a corner rounding machine for hardware processing. Utility Model Content

[0014] 2. The utility model presses the two connecting clamps so that the connecting clamps squeeze the stretching elastic force of the two extension springs. This operation makes the lower end of the connecting clamp move horizontally, thereby making the connecting clamp disengage from the clamping groove at the bottom end of the fixing groove. At this time, the two connecting clamps can be detached from the through hole and the fixing groove. Finally, the two connecting clamps no longer clamp and fix the clamping frame and the tool connecting frame. The tool connecting frame and the clamping frame are disassembled. Since the tool connecting frame and the angle grinding tool are an integral whole, the disassembly of the tool connecting frame will cause the angle grinding tool to be disassembled and replaced. This arrangement makes the overall angle grinding tool replaceable with fillets of different types and specifications. The arrangement of the connecting clamp and the extension spring replaces the existing bolt and nut connecting parts. In the absence of tools, the user only needs to press the connecting clamp to realize the rapid disassembly of the tool connecting frame and the angle grinding tool, making the replacement of the angle grinding tool convenient and quick.

[0023] The user presses the two connecting card plates 13, which makes the two connecting card plates 13 squeeze the stretching elasticity of the two stretching springs 15, so that the two connecting card plates 13 are inserted into the through hole 12 and the inside of the fixing groove 14, and the lower end of the connecting card plate 13 is connected to the lower end of the fixing groove 14, wherein both sides of the bottom end of the fixing groove 14 are provided with a clamping groove, and the transverse section of the bottom end of the connecting card plate 13 is inserted into the clamping groove inside the fixing groove 14.
