[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: a novel nut welding equipment, comprising: a machine base 1; a welding fixture 2 and a resistance welding machine 3 are respectively provided on the top of the machine base 1, and an air extraction mechanism is provided on the top of the machine base 1 near the welding fixture 2;
[0025] The air extraction mechanism includes a connecting seat 4 fixedly connected to the top of the machine base 1, a connector 5 detachably connected to the top of the connecting seat 4, and a bamboo joint universal tube 10 fixedly connected to one end of the connector 5. The connecting seat 4 has a cavity inside, and the end of the connector 5 away from the bamboo joint universal tube 10 is inserted into the cavity and is detachably connected to an air filter tube 6.
[0026] During resistance welding, the high temperature causes coatings, oil, and metal to evaporate, producing fumes and harmful gases. The extraction mechanism creates a local negative pressure near the welding point through the bamboo-joint universal tube 10, which accurately sucks away the fumes. After the filter tube filters impurities, the fumes are discharged through the connecting seat 4, realizing localized fixed-point extraction in the welding area, effectively removing welding fumes. The extraction system has a modular structure and is easy to disassemble and maintain.
[0027] More preferably, the top of the connector 4 is provided with an insertion hole 7 that communicates with its cavity, and the connector 5 and the connector 4 are provided with multiple matching threaded holes, and fastening bolts 8 are threaded through to achieve locking.
[0028] After the connector 5 is inserted into the connector 4, it is locked with bolts to prevent loosening during use. It is easy to disassemble and assemble, and easy to replace the connector 5 or clean the pipeline. The socket 7 provides a channel for the connector 5 to be inserted, ensuring gas flow between the connector 5 and the connector 4.
[0029] More preferably, the connecting ends of the connector 5 and the air filter tube 6 are respectively provided with matching threads, and the air filter tube 6 is connected to the connector 5 through the threads and inserted into the cavity of the connecting seat 4;
[0030] The air filter tube 6 and the connector 5 are securely connected by a threaded connection. The air filter tube 6 is inserted into the connector 4 to form a complete air extraction path. The air filter tube 6 has activated carbon inside, which can initially filter out particulate matter and odors in the smoke.
[0031] More preferably, one end of the connecting seat 4 is fixedly connected to an external pipe 9 that communicates with its cavity. The external pipe 9 is used to connect to the external exhaust pump body to realize the exhaust function.
[0032] The external pipe 9 serves as an exhaust port, connecting to an air pump to establish a negative pressure channel. The air pump drives the airflow, allowing the gas in the welding area to flow in and be discharged to subsequent processing equipment.
[0033] In a further preferred embodiment, the end of the bamboo joint universal tube 10 away from the connector 5 is fixedly connected to a horn tube head 12, which is used to increase the air intake range and improve the air extraction efficiency.
[0034] The horn-shaped design of the horn head 12 increases the inlet area and improves the air extraction coverage area. Combined with the bamboo joint universal tube 10, the angle can be adjusted so that the horn mouth is aligned with the pollution source. It can be flexibly positioned for different work positions, improving adaptability.
[0035] In a further preferred embodiment, the air passages of the connector 5, the bamboo joint universal tube 10, and the air filter tube 6 are connected to form a continuous air extraction channel;
[0036] Connector 5, bamboo joint universal tube 10 and air filter tube 6 are connected to form an air extraction channel. The three form a continuous pipeline with a single air extraction channel inside.
[0037] More preferably, a rubber ring 11 is fitted on the end of the connector 5 facing the connecting seat 4, and the connector 5 is installed on the connecting seat 4 to improve the sealing performance;
[0038] The rubber ring 11 forms a flexible seal between the contact surfaces of the joint 5 and the connecting seat 4, preventing air leakage due to tiny gaps at the interface.
[0039] A specific application of this embodiment is as follows: Based on the actual working position of the welding fixture 2 and the resistance welding machine 3, one end of the horn tube head 12 of the bamboo joint universal tube 10 of the air extraction mechanism can be adjusted to be closest to the welding point without affecting the processing. Then, the operator can fix the workpiece to be welded on the welding fixture 2, start the resistance welding machine 3 to weld the nut, and at the same time start the external air extraction pump for exhaust. The recently generated smoke and dust is sucked in by the horn tube head 12 and guided through the bamboo joint universal tube 10 and the connector 5. The bamboo joint universal tube 10 can flexibly adjust the air extraction direction according to different welding points. After the air is pre-filtered by the air filter tube 6, and finally discharged through the connecting seat 4 and the external pipe 9, it is discharged to the subsequent processing equipment to achieve effective exhaust. During maintenance, the air extraction mechanism connector 5 is a detachable structure, and the air filter tube 6 can be disassembled and replaced without affecting the machine 1.
