Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a smoking nozzle of a smoking welding gun. Background Art

[0002] The function of the smoke nozzle is to clean the welding smoke from the source before it floats and spreads. Existing smoke nozzles usually use two methods: end face smoking and circumferential smoking. The smoking range is not concentrated and the dust removal rate is low. At the same time, the smoke nozzle is installed at the nozzle of the welding gun, which affects the observation of the weld during welding. Summary of the invention

[0003] In view of the above shortcomings, the present invention discloses a smoking nozzle, which comprises a connecting part, a smoking nozzle body, a smoking nozzle slope, and a high temperature resistant transparent glass cover in sequence. It is installed at the front end of the gun barrel, and the new smoking nozzle body and the high temperature resistant transparent glass cover are installed above the smoking hole and connected into one body using high temperature resistant glue to form a smoking port with a focused smoking area. The transparent glass cover extends the eaves to block the air other than the smoke from entering the smoking nozzle, thereby enhancing the suction effect on the smoke. The variable cross-section channel further increases the smoking effect.

[0004] The technical solution of the present invention is: a smoking mouthpiece, comprising a smoking mouthpiece body in a tubular structure;

[0005] The tail end of the smoking nozzle body is provided with a connecting portion which can be detachably fixedly connected to the curved pipe;

[0006] A smoking hole is provided on the circumferential surface of the smoking nozzle body, and a high temperature resistant transparent glass cover is provided above the smoking hole;

[0007] The heat-resistant transparent glass cover includes a glass inclined plate on the top and glass side panels on the left and right sides. The bottom end surface of the heat-resistant transparent glass cover composed of the glass inclined plate and the glass side panels on the left and right sides is fixedly connected to the smoking nozzle body around the smoking hole by high-temperature resistant glue, and the opening of the heat-resistant transparent glass cover faces the head end of the smoking nozzle body. The heat-resistant transparent glass cover and the smoking hole form a smoking port with a focused smoking area. The new smoking nozzle body and the heat-resistant transparent glass cover form a smoking channel with a variable cross-section, with the largest opening at the front end and a smaller cross-section in the middle channel. The large opening at the front end is conducive to the suction of the smoke dust range, and the smaller cross-section in the middle channel can increase the negative pressure of the channel and improve the smoking effect.

[0008] Furthermore, a transparent glass cover eave protrudes from the front end of the glass inclined plate, and the transparent glass cover eave blocks air other than smoke from entering the smoking nozzle, further enhancing the suction effect on smoke.

[0009] Furthermore, the connecting part includes an elastic clamp and an elastic claw connected to the tail end of the elastic clamp. The connecting part is elastically connected and installed on the curved pipe through the joint action of the clamp and the elastic clamp, which helps to quickly install and remove the smoking mouthpiece. The elastic connection can adjust the smoking port in the axial and circumferential directions according to different usage scenarios to the position where smoke is generated, thereby improving the smoking effect.

[0010] Furthermore, the head end of the mouthpiece body is provided with a mouthpiece slope that contracts radially. The mouthpiece slope is a large inclined surface, which ensures that the path for smoke to be sucked into the mouthpiece is unobstructed and reduces the dispersion of smoke.

[0011] Furthermore, the inclination angle of the glass inclined plate is 5°~60°.

[0012] Furthermore, the outer diameter of the mouthpiece body ranges from 20 to 50 mm.

[0013] Furthermore, the material of the mouthpiece body is preferably aluminum, and other materials include but are not limited to copper, steel, ceramic, glass, etc.

[0014] Furthermore, the width of the high temperature resistant transparent glass cover ranges from 10 to 50 mm.

[0015] Furthermore, the material of the high temperature resistant transparent glass cover is preferably glass, and other materials include but are not limited to copper, steel, ceramic, aluminum, etc.

[0016] The beneficial effects of the present invention are as follows: the new smoking mouthpiece body and the high temperature resistant transparent glass cover are installed above the smoking hole and connected into one piece by using high temperature resistant glue. The high temperature resistant transparent glass cover and the smoking hole form a smoking port with a focused smoking area, and the eaves of the transparent glass cover are extended to block air other than smoke from entering the smoking mouthpiece, further enhancing the suction effect on smoke.

[0017] The new smoking nozzle body and the high temperature resistant transparent glass cover form a variable cross-section smoking channel, with the largest opening at the front end and a smaller cross-section in the middle. The large opening at the front end is conducive to the suction of smoke and dust coverage, and the smaller cross-section in the middle channel can increase the negative pressure of the channel and improve the smoking effect.

[0018] The high temperature resistant transparent glass cover is made of transparent and high temperature resistant material to reduce obstruction and facilitate operation and observation of the welding process.

[0019] The slope of the smoking mouthpiece is a large inclined surface, which reduces the obstruction of the smoking port, increases the smoothness of the path for smoke to be sucked into the smoking port, and improves the smoking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figures 1 to 7 A smoking nozzle is shown, which is installed at the end of a gun barrel. The smoking nozzle comprises a connecting portion 1, a smoking nozzle body 2, a smoking nozzle slope 3, and a high temperature resistant transparent glass cover 4 in sequence. The connecting portion 1 is installed on the curved pipe 6 through an elastic connection. The circumference of the smoking nozzle body 2 includes a smoking hole 12, and the high temperature resistant transparent glass cover 4 is installed above the smoking hole 12 and connected to the smoking nozzle body by a high temperature resistant glue 5. Specifically, the high temperature resistant transparent glass cover 4 includes a glass inclined plate at the top and glass side plates on the left and right sides. The bottom end surface of the high temperature resistant transparent glass cover 4 composed of the glass inclined plate and the glass side plates on the left and right sides is fixedly connected to the smoking nozzle body 2 around the smoking hole 21 through a high temperature resistant glue 5, and the opening of the high temperature resistant transparent glass cover 4 faces the head end of the smoking nozzle body 2. The high temperature resistant transparent glass cover 4 and the smoking hole 12 form a smoking port with a focused smoking area to improve the smoking effect. The high temperature resistant transparent glass cover 4 is made of transparent and high temperature resistant material to reduce obstruction and facilitate operation and observation of the welding process.

[0035] In the embodiment, the connecting portion 1 of the novel smoking nozzle is installed on the curved pipe 6 by means of an elastic connection formed by the claws 12 and the elastic clamping ring 11. The elastic connection helps to quickly install and remove the smoking nozzle.

[0036] Preferably, the elastic connection can adjust the smoking port in the axial and circumferential directions to the position where smoke is generated according to different usage scenarios, thereby improving the smoking effect.

[0038] Furthermore, the new smoking nozzle body 2 and the high temperature resistant transparent glass cover 4 form a smoking passage with a variable cross section, with the largest opening at the front end and a smaller cross section in the middle passage. The large opening at the front end is conducive to the suction of the smoke dust range, and the smaller cross section in the middle passage can increase the negative pressure of the passage and improve the smoking effect.

[0039] Preferably, the high temperature resistant transparent glass cover 4 is made of a transparent high temperature resistant material to reduce obstruction and facilitate observation of the welding process.

[0040] In the embodiment, the mouthpiece slope 3 is a large slope, which reduces the obstruction of the mouthpiece, increases the smoothness of the path for smoke to be sucked into the mouthpiece, and improves the smoking effect.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
