Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic welding, and particularly relates to a welding wire feeding device for constantan wire and nichrome wire. Background Art
[0002] Gas equipment generally uses a thermocouple as a flameout protection device, and the thermocouple is generally constantan wire and nichrome wire.
[0003] Constantan wire is a resistance alloy mainly composed of copper and nickel, with a low resistance temperature coefficient and good workability. In gas equipment, constantan wire is used as a resistance element to regulate and control gas flow and the negative electrode of the thermocouple. Due to its stable resistance value and good welding performance, constantan wire cooperates with the positive electrode of the thermocouple to generate electromotive force, drive the solenoid valve, and ensure the normal operation and safe use of gas equipment.
[0004] Nichrome wire is an alloy mainly composed of nickel and chromium, which is widely used in gas equipment and can be used as an ignition needle, the positive electrode of the thermocouple, etc.
[0005] In the production process of gas equipment, the raw materials of constantan wire and nichrome wire are both coils, and a wire feeding device is required to feed them into the subsequent processing equipment. The main body of the existing wire feeding device is two tangent rollers, and the constantan wire and nichrome wire are clamped between the two rollers and fed as the rollers rotate. However, after long-term use of this wire feeding device, it is found that it has two serious defects:
[0006] 1. It is difficult to adjust the pre-tightening force of the two tangent rollers; when the rollers are loose, the constantan wire and nichrome wire will slip on the rollers, affecting the wire feeding accuracy and causing insufficient subsequent welding length; when the rollers are tight, it is easy to cause deformation and indentation of the constantan wire and nichrome wire;
[0007] 2. After long-term use, the surfaces of the rollers are worn, which is likely to cause scratches on the surfaces of the constantan wire and nichrome wire. Summary of the Utility Model
[0008] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a welding wire feeding device for constantan wire and nichrome wire, which is used to solve the technical problem that the existing wire feeding device has various defects and affects the product quality.
[0009] The technical solution for the utility model to solve the above technical problems is as follows: A welding wire feeding device for constantan wire and nichrome wire, comprising:
[0010] A frame;
[0011] A moving platform, which is arranged on the frame, and the moving platform is connected to the frame through a slide rail and is driven by a linear motion mechanism;
[0012] The jaw cylinder is provided on the moving platform. A clamp is further provided on the jaw of the jaw cylinder. A limiting hole is opened on the clamp, and the limiting hole is adapted to the constantan wire and the nichrome wire.
[0013] The biggest difference between the present utility model and the prior art lies in the difference in the contact length between the wire feeding device and the constantan wire and the nichrome wire. In the prior art, the rollers of the wire feeding device always maintain a tangent state with the constantan wire and the nichrome wire, while in this application, the clamp of the jaw cylinder clamps one place of the constantan wire and the nichrome wire, and then the moving platform makes a linear motion to drag the constantan wire and the nichrome wire to move. Then the clamp is loosened, and after resetting, it repeats clamping and wire feeding. The contact surface between the clamp and the constantan wire and the nichrome wire is intermittent; therefore, this application can greatly reduce the influence of the wire feeding device on the constantan wire and the nichrome wire; in addition, due to the clamping effect of the clamp and the reciprocating linear motion of the moving platform, the wire feeding length can be ensured to be stable and the welding effect will not be affected.
[0014] Furthermore: An installation seat is further provided on the jaw cylinder. A wire protection tube is inserted into the installation seat, and the wire protection tube is perpendicular to the clamp.
[0015] Beneficial effects of this step: The wire protection tube can not only guide the constantan wire and the nichrome wire to be perpendicular to the clamp, making it more convenient for the clamp to clamp the constantan wire and the nichrome wire, but also protect the appearance of the constantan wire and the nichrome wire, avoiding friction with parts such as the jaw cylinder during the movement process.
[0016] Furthermore: A wire fastening bolt is provided on the side of the jaw of the jaw cylinder.
[0017] Beneficial effects of this step: The wire fastening bolt plays a role in fixing the welding machine wire, enabling the clamp, the constantan wire, the nichrome wire, etc. to form an electric current loop for convenient welding.
[0018] Furthermore: The clamp includes a left clamp and a right clamp. A plurality of fins are oppositely provided on both the left clamp and the right clamp, and the fins are arranged in a staggered manner.
[0019] Beneficial effects of this step: The plurality of fins can effectively play a role in clamping and fixing.
[0020] Furthermore: Limit blocks are provided at both ends of the slide rail.
[0021] Beneficial effects of this step: The limit blocks play a role in restricting the movement stroke of the moving platform.
[0022] Furthermore: The position of the limit block is adjustable.
[0023] Beneficial effects of this step: The position of the limit block is adjustable, which means the stroke of the moving platform is adjustable, that is, the single-wire feeding length can be adjusted according to the single-use length of the constantan wire and the nichrome wire.
[0024] The beneficial effects of the present utility model are:
[0025] 1. The feeding action of the constantan wire and the nichrome wire is realized by using the moving platform and the jaw cylinder. The jaw cylinder can ensure the fastening degree of clamping the constantan wire and the nichrome wire, and can stably feed a fixed length without affecting the welding effect;
[0026] 2. Compared with the roller of the prior art, the clamp has a smaller contact length with the constantan wire and the nichrome wire during the wire feeding process, and can greatly reduce the influence on the surface of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment
[0040] As Figure 1 and Figure 2 shown, a kind of constantan wire and nichrome wire welding wire feeding device provided by the present utility model includes:
[0041] A frame 1, which is composed of two oppositely arranged vertical plates;
[0042] The mobile platform 2 is provided on the frame 1, and the mobile platform 2 is connected to the frame 1 through a slide rail 21. The mobile platform 2 is driven by a linear motion mechanism 11. In this embodiment, steps are provided on the vertical plate of the frame 1, and the slide rail 21 is laid on the steps for connecting to the bottom surface of the mobile platform 2. The linear motion mechanism 11 selects an ordinary air cylinder, and the output shaft of the air cylinder is fixedly connected to the bottom surface of the mobile platform 2. The air cylinder drives the mobile platform 2 to achieve reciprocating motion.
[0043] The jaw cylinder 3 is provided on the mobile platform 2. The jaws of the jaw cylinder 3 can achieve opening and closing movements. A clamp 4 is further provided on the jaws of the jaw cylinder 3. A limiting hole is opened on the clamp 4, and the limiting hole is adapted to the constantan wire and the nichrome wire, and the constantan wire and the nichrome wire are the wire material 7.
[0044] The biggest difference between the present utility model and the prior art lies in the difference in the contact length between the wire feeding device and the constantan wire and the nichrome wire. In the prior art, the roller of the wire feeding device always maintains a tangential state with the constantan wire and the nichrome wire, while in this application, the clamp 4 of the jaw cylinder 3 clamps a part of the constantan wire and the nichrome wire, and then the mobile platform 2 performs a linear motion to drag the constantan wire and the nichrome wire to move. Then the clamp 4 is loosened, and after resetting, it repeats clamping and wire feeding. The contact surface between the clamp 4 and the constantan wire and the nichrome wire is intermittent. Therefore, this application can greatly reduce the influence of the wire feeding device on the constantan wire and the nichrome wire. In addition, due to the clamping effect of the clamp 4 and the reciprocating linear motion of the mobile platform 2, the wire feeding length can be ensured to be stable and the welding effect will not be affected.
[0045] On the basis of the above technical solution, an installation seat 5 is further provided on the jaw cylinder 3. A wire protection tube 6 is inserted into the installation seat 5. The wire protection tube 6 is perpendicular to the clamp 4, and the wire material 7 passes through the wire protection tube 6.
[0046] The wire protection tube 7 can not only guide the constantan wire and the nichrome wire to be perpendicular to the clamp 4, making it more convenient for the clamp 4 to clamp the constantan wire and the nichrome wire, but also play a role in protecting the appearance of the constantan wire and the nichrome wire, preventing them from rubbing against parts such as the jaw cylinder 3 during the movement process.
[0047] On the basis of the above technical solution, a wire fastening bolt 42 is provided on the side of the jaws of the jaw cylinder 3.
[0048] The wire fastening bolt 42 plays a role in fixing the welding machine wire, enabling the clamp 4, the constantan wire, the nichrome wire, etc. to form an electric current loop for convenient welding.
[0049] On the basis of the above technical solution, the clamp 4 includes a left clamp and a right clamp. A plurality of fins 41 are oppositely provided on both the left clamp and the right clamp, and the fins 41 are arranged in a staggered manner.
[0050] A number of fins 41 can effectively play a role in clamping and fixing.
[0051] On the basis of the above technical solution, limit blocks are provided at both ends of the slide rail 21.
[0052] The limit blocks play a role in restricting the moving stroke of the moving platform 2.
[0053] On the basis of the above technical solution, the positions of the limit blocks are adjustable.
[0054] The adjustable positions of the limit blocks mean that the stroke of the moving platform 2 is adjustable, that is, the single wire feeding length can be adjusted according to the single use length of the constantan wire and the nichrome wire.
[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
