Description

Technical Field

[0001] The utility model relates to the technical field of electrode cap grinding, in particular to a chip collecting device for a grinding machine. Background Art

[0002] In the field of automobile body-in-white welding, electrodes are used for body-in-white welding. During long-term welding, the end surface of the electrode will produce a high-hardness oxide layer. If it is not ground, it will have a great impact on the welding quality of the body-in-white, which may cause false welding. Insufficient welding strength seriously affects the strength of the entire vehicle, so it needs to be ground. At present, in fully automatic welding factories, robots control electrodes to insert into the tool nest of the grinding machine for grinding; during the grinding process, copper chips will be cut off from the electrode, and these copper chips will fall and pollute the working environment.

The electrode grinding waste chip collection device is installed on the electrode grinding device (grinding machine) when in use, and it uses the air blowing device to assist in collecting copper chips and send the copper chips into the chip discharge port, through the chip guide pipe, and flows to the copper chip storage, which can avoid copper chips splashing when the electrode cap is ground, and can collect and store the copper chips generated during grinding.

[0004] However, since the electrode grinding waste chip collection device is in an open state, during use, since no blocking structure is provided, the collection rate of copper chips is relatively low, resulting in a large amount of copper chips spilling on the ground and a poor chip collection effect.

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] See also Figures 1 to 4As shown, the technical solution discloses a chip collecting device for a grinding machine, including a dust collecting shell 100, wherein the interior of the dust collecting shell 100 has a cavity, and the cavity provides a space for the grinding machine to grind the electrode. The dust collecting shell 100 is mainly used to limit copper chips; one of the side walls of the dust collecting shell 100 has an opening 101 for the grinding machine to extend into, and the patent document "202221026112.0" discloses an electrode cap grinding and shaping machine, wherein the opening 101 is used for the grinding mechanism of the grinding and shaping machine to extend into the cavity; refer to the patent document "202221026112.0" for details. Figure 1 As shown, the upper and lower surfaces of the dust collecting shell 100 are fixed with a barrier 200 for preventing copper chips from flying out. The central part of the barrier 200 has a through hole 201 for inserting the electrode to be ground. The through hole 201 on the barrier 200 allows the electrode to be ground to smoothly enter the dust collecting shell 100 for grinding. At the same time, the barrier 200 can also prevent the copper chips generated by grinding from flying out of the dust collecting shell. In addition, after the grinding process is completed, due to the existence of the barrier 200, the copper chips on the electrode can be brushed off, which greatly improves the chip collection efficiency and prevents the copper chips from flying out. The dust collecting shell 100 is connected to the blowing device, and the dust collecting shell 100 also has a chip discharge port, which is connected to the chip collecting barrel 400 through the pipe 300.

During the grinding process, the blowing device works to blow air into the dust collecting shell 100, and the copper chips ground off enter the pipe 300 through the chip discharge port through the blowing device until the copper chips enter the chip collecting barrel 400. During this working process, due to the presence of the barrier 200, the copper chips can be prevented from flying out to a large extent. When the electrode is ground, the electrode is separated from the barrier 200, and the waste chips stuck on the electrode can be brushed off by relying on the barrier 200.
