Description

Technical Field

[0001] The utility model belongs to the technical field of handicraft processing devices, and in particular relates to a handicraft welding processing gun. Background Art

[0002] The welding torch for gold processing, also known as a gold melting torch or high-temperature spray gun, is a tool that uses a high-temperature flame to melt, weld, or heat-anneal metal materials such as gold and silver. It is widely used in the fields of gold and silver jewelry making, watch and eyewear repair, and musical instrument repair. When operating the welding torch, it is necessary to aim the torch's flame at the metal material to be processed, maintain a safe distance, and perform operations such as melting or welding the metal material.

[0003] When operating a welding torch, the operator needs to hold the torch and aim it at the metal material. If the metal material is simply melted, the operator only needs to hold the torch and heat the metal material continuously. However, if the metal material needs to be softened by high-temperature heating of the torch and then welded or twisted, the operator needs to use both hands to operate the metal material. The torch needs to be placed aside and can be used to heat the metal material at any time. However, since the operator's hands are processing the metal material, the torch cannot be held fixedly.

DETAILED DESCRIPTION

[0046] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Example 1

[0048] A craft welding torch, comprising: a welding torch 1, a clamping sleeve 3, a support and adjustment component, and a fixed base clamp 4;

[0049] The welding torch 1 in this embodiment is an existing product, and this embodiment does not improve the structure of the welding torch 1 itself; therefore, the structure and working principle of the welding torch 1 itself will not be described in detail in this embodiment.

[0050] like Figure 1 As shown, the head end of the welding gun 1, which is equivalent to the right end in the figure, is the flame nozzle of the welding gun 1; the tail end of the welding gun 1, which is equivalent to the left end in the figure, is the fuel inlet end 101 of the welding gun 1; and the hand grip of the welding gun 1 is close to the fuel inlet end 101. When operating the welding gun 1, the operator holds the hand grip to maintain a certain distance between the welding gun 1 and the metal material to be processed, so as to keep the welding gun 1 stable and heat the metal material.

[0051] If only metal materials such as gold and silver need to be melted, then only the welding torch 1 needs to be held; however, if gold and silver crafts need to be welded or they need to be twisted and deformed after being heated to achieve the desired modeling effect, the operator needs to use both hands to operate. During the operation, the welding torch 1 needs to be used to heat the metal material to soften the metal material for easy operation. However, since both hands are operating at this time, the welding torch 1 cannot be held and fixed.

[0052] like Figure 1 As shown, a detachable clamping sleeve 3 is provided at the hand grip of the welding torch 1; the function of the clamping sleeve 3 is to clamp and fix the welding torch 1; Figure 3 As shown, the clamping sleeve 3 is a cylindrical structure, the interior of the clamping sleeve 3 is hollow, and both ends are open structures; the upper part of the clamping sleeve 3 is set as an open structure, and vertical attachment plates 301 are integrally formed on both sides of the opening structure. Screw holes are provided on the two attachment plates 301, and the screw holes on the two attachment plates 301 are symmetrical; a locking screw 302 is detachably inserted into the screw hole, and locking screw sleeves 303 are provided at both ends of the locking screw 302; from the tail end near the welding torch 1, that is, the fuel inlet end 101, 301 , and then the clamping sleeve 303 is tightened to the upper end of the clamping sleeve 3. When the clamping sleeve 303 is tightened, the welding torch 1 is tightened.

[0053] like Figure 1 As shown, the first end of the support adjustment assembly is arranged below the clamping sleeve 3, and the second end of the support adjustment assembly is arranged on the fixed base clamp 4; the support adjustment assembly can adjust the height of the fusion welding torch 1 in the vertical direction, which is equivalent to adjusting the distance between the flame nozzle of the fusion welding torch 1 and the metal material; in addition, the support adjustment assembly can also adjust the inclination angle of the fusion welding torch 1, that is, it can change the flame ejection direction of the flame nozzle of the fusion welding torch 1.

[0054] like Figure 2 As shown, the above-mentioned support adjustment assembly includes: a hinge seat 5, a hinge plate 6 and a telescopic rod 7;

[0055] The hinge seat 5 is an "n"-shaped structure, with its opening facing downward and centrally located below the clamping sleeve 3. The first end of the hinge plate 6 is disposed within the hinge seat 5, and a hinge screw passes through the hinge seat 5 and the hinge plate 6. Nuts are disposed at both ends of the hinge screw. In this way, the welding torch 1 fixed within the clamping sleeve 3 can be rotated to adjust its tilt angle with the cooperation of the hinge seat 5 and the hinge plate 6. Adjusting the tilt angle of the welding torch 1 can change the direction of the flame ejection from its nozzle.

[0056] The second end of the hinged plate 6 is mounted on the first end of the telescopic rod 7; the second end of the telescopic rod 7 is mounted on the clamping plate above the fixed base clamp 4. The telescopic rod 7 comprises a base section and a telescopic section. The lower end of the telescopic section is movably mounted within the base section. A locking knob is provided near the upper end of the base section and on the side wall of the base section. Turning the locking knob presses against the telescopic section, preventing it from being raised or lowered. Turning the locking knob releases the locking knob, allowing it to be raised or lowered relative to the base section. The upper end of the telescopic section constitutes the first end of the telescopic rod 7, and the lower end of the base section constitutes the second end of the telescopic rod 7. By adjusting the height of the upper welding torch 1 via the telescopic rod 7, the distance between the burner nozzle and the metal material to be melted can be adjusted.

[0057] like Figure 2 As shown, the fixed base clamp 4 includes two parallel clamping plates, each of which has an integrally formed connecting pressing portion; the intersection of the two clamping plates is hinged by a rotating shaft; a spring coil is provided between the two clamping plates, so that the entire fixed base clamp 4 has a clamping force. When force is applied to the pressing portion, the two clamping plates open and are placed on the side edge of the operating table. The two clamping plates are then clamped and fixed to the side edge of the operating table. In this way, the fixed base clamp 4 fixes the entire support adjustment assembly, the hinge seat 5, the hinge plate 6, and the welding gun 1 on the operating table, so that the welding gun 1 is placed stably. The operator does not need to hold the welding gun 1 by hand to fix it. In this way, the operator can process gold and silver crafts with both hands without affecting the use of the welding gun 1.

[0058] As a preferred embodiment, in order to ensure sufficient friction between the fixed base clamp 4 and the operating table to prevent the fixed base clamp 4 from sliding easily relative to the operating table, anti-slip pads 401 are provided on the opposite surfaces of the two clamping plates of the fixed base clamp 4; the anti-slip pads 401 are made of rubber material, and protective lines or raised point structures can be provided on the contact surface with the operating table to enhance friction.

[0059] Example 2

[0060] Based on Example 1, in Example 1, a clamping sleeve 3 is provided, and a support adjustment component and a fixed base clamp 4 are used to clamp and fix the welding torch 1 together, and the distance between the burner nozzle and the metal material can be adjusted, as well as the direction of the flame ejection at the burner nozzle; thus, the handheld welding torch 1 can be completely replaced for operation.

[0061] However, in addition to using the structure provided in the above embodiment 1 to support, fix and adjust the welding torch 1, you can also directly hold the hand grip to fix the welding torch 1 yourself for operation; however, during operation, the flame temperature at the nozzle of the welding torch 1 is relatively high, which may cause a high temperature burning sensation to the hands.

[0062] like Figure 4 As shown, in this embodiment, a heat-insulating sleeve 8 is detachably provided at the hand grip of the welding torch 1. When holding the welding torch 1, the heat-insulating sleeve 8 can isolate the hand and prevent the hand from being subjected to the heat radiation of the torch; Figure 5 As shown, the heat-insulating sleeve 8 is configured as a cylindrical structure with a hollow interior and an opening on the left side; a notch is configured below the cylindrical structure to facilitate placement of the hand inside the heat-insulating sleeve 8;

[0063] A circular through hole 801 is provided at the center of the right side of the thermal insulation sleeve 8. The diameter of the circular through hole 801 is larger than the diameter of the hand holding portion of the welding torch 1. The welding torch 1 is passed through the through hole 801 to pass through the thermal insulation sleeve 8, thereby placing the thermal insulation sleeve 8 on the welding torch 1. When the thermal insulation sleeve 8 is placed on the welding torch 1, the diameter of the through hole 801 is preferably set so that the inner edge of the through hole 801 contacts the outer wall of the welding torch 1, and the gap between the two is as small as possible. The thermal insulation sleeve 8 is made of a high-temperature resistant material.

[0064] An insulation layer 802 is provided on the inner wall of the insulation sleeve 8 , and the insulation layer 802 is made of a heat-insulating material; the insulation layer 802 further enhances the effect of the insulation sleeve 8 in blocking heat radiation.

[0065] Example 3

[0066] Based on Example 1, in Example 1, the fuel inlet end 101 of the welding torch 1 is connected to the fuel connecting pipe 2, and the volatile fuel enters the welding torch 1 from the fuel inlet end 101 through the fuel connecting pipe 2 to provide ignition fuel;

[0067] In order to ensure the tightness of the connection between the fuel inlet end 101 and the fuel connecting pipe 2, to prevent the fuel connecting pipe 2 from coming out of the fuel inlet end 101, or to prevent fuel leakage at the connection between the two; Figure 6 As shown, after the fuel connecting pipe 2 is docked with the fuel inlet end 101, the two are fastened together using a tightening ring band 9;

[0068] like Figure 7 As shown, the tightening band 9 has an open top; screw holes are provided on the tightening band 9 near both sides of the openings; locking screws 302 are removably inserted through the screw holes; and locking screw sleeves 303 are provided at both ends of the locking screws 302. The portion of the tightening band 9 that fits over the fuel connecting pipe 2 is made of a resilient synthetic metal material; the portion where the locking screws 302 are located is made of a hard metal material. By tightening the locking screw sleeves 303, the tightening band 9 securely binds the fuel connecting pipe 2 to the fuel inlet port 101.

[0069] As a preferred embodiment, Figure 6 As shown, a plurality of concave annular grooves 1011 are provided at equal intervals on the outer side wall of the fuel inlet end 101; the width of the concave annular grooves 1011 is greater than the width of the tightening ring band 9;

[0070] After the tightening band 9 is fastened to the fuel connecting pipe 2 and the fuel inlet end 101, the tightening band 9 is located in the concave annular groove 1011. The concave annular groove 1011 can prevent the tightening band 9 from sliding and shifting, ensuring that the tightening is tight, preventing the fuel connecting pipe 2 from loosening or leakage at the joint between the fuel connecting pipe 2 and the fuel inlet end 101.
