Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding torch for an automated welding machine and an automated welding machine. Background Technology

[0002] Automatic welding equipment is a specialized device that automates welding operations through mechanical structures and electrical control systems. It is widely used in industries such as construction machinery, automotive parts, and steel structure processing. Automatic welding equipment mainly consists of a frame, transmission mechanism, welding torch assembly, control system, and welding power supply. However, currently, during operation, automatic welding equipment experiences several issues. These include workpiece dimensional deviations, inadequate clamping and positioning, and deformation or displacement due to welding heat. These issues can cause interference with the welding torch's path, leading to torch collisions. Once a collision occurs, it can damage the welding torch nozzle and the workpiece. Furthermore, some automatic welding equipment may fail to accurately detect collisions, resulting in sudden stops even when the collision is not obvious, thus impacting work efficiency. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, the present invention provides a welding torch for an automated welding machine and an automated welding machine. The welding torch, through the setting of a protector, receives an electrical signal when the torch head collides with the workpiece and transmits it to the controller. The controller then controls the automated welding machine to stop working, preventing the torch head from continuing to contact the workpiece, thus avoiding damage to both the torch head and the workpiece and improving their service life. A first locking position and a second locking position are formed by a positioning plate. When encountering external force, the torch head slides from the first locking position into the second locking position and contacts the contact part on the positioning plate to generate an electrical signal. This process requires overcoming the resistance at the connection between the first and second locking positions, improving the accuracy of signal acquisition when the torch head and workpiece come into contact, increasing work efficiency, and simplifying the structure.

[0005] Specifically, the following technical solutions are included:

[0006] According to a first aspect of this utility model, a welding torch for an automated welding machine is provided. The automated welding machine includes a controller, and the welding torch is electrically connected to the controller. The welding torch includes:

[0013] When the welding torch is working normally, the torch head is engaged with the first locking position; when the welding torch encounters an obstacle, the torch head is engaged with the second locking position.

[0014] The positioning piece includes:

[0017] The contact portion is configured at one end of the pair of second C-shaped snap-fit ​​portions that is away from the pair of first C-shaped snap-fit ​​portions.

[0018] Optionally, the protector includes a first latching position and a second latching position. When the gun head latches with the second latching position, the gun head and the protector generate an electrical signal. The electrical signal is transmitted to the controller through the protector, and the controller controls the automated welding machine to stop working.

[0019] Optionally, the protector further includes:

[0020] Abutting blocks, a plurality of abutting blocks are evenly arranged on the side of the mounting ring facing the welding gun body, and a positioning piece is provided between two adjacent abutting blocks.

[0022] Optionally, the positioning piece further includes:

[0023] A connecting portion is disposed at the end of the first C-shaped latching portion away from the second C-shaped latching portion, and the connecting portion is used to connect the first C-shaped latching portion and the abutting block.

[0024] Optionally, the mounting ring has a wiring terminal on the side opposite to the welding torch body, one end of the wiring terminal is electrically connected to the contact part, and the other end of the wiring terminal is electrically connected to the controller.

[0025] Optionally, the gun head includes:

[0026] The spearhead itself;

[0027] An insert plate is disposed on the side of the torch head body facing the welding torch body;

[0028] A plug rod is located at the end of the plug plate away from the gun head body;

[0029] A snap-fit ​​connector is disposed on the side of the insertion rod away from the insertion plate, and the snap-fit ​​connector matches the first snap-fit ​​position or the snap-fit ​​connector matches the second snap-fit ​​position;

[0030] The gun head is located on the side of the mounting ring facing the welding gun body, and the gun head is fitted onto the welding gun body.

[0031] Optionally, the gun head includes a plurality of the insert plates, with two adjacent insert plates forming a positioning groove.

[0032] A second aspect of this utility model provides an automated welding machine, the automated welding machine comprising:

[0033] The welding torch described above includes a welding torch body and a protective device;

Part of the torch head is snapped into connection with the protector, and the protector is also electrically connected to the controller. When the welding torch is working normally, the protector does not generate an electrical signal. When the welding torch interferes with the workpiece, the torch head is pressed against the workpiece, creating pressure. This pressure pushes the torch head to move within the torch body and the protector until the position where the torch head moves triggers the protector, generating an electrical signal. This signal is then transmitted to the controller. Upon receiving the signal, the controller stops the automated welding machine to prevent the torch head from continuing to press against the workpiece and causing damage, thus extending the service life of the welding torch and the workpiece and effectively preventing further damage caused by collisions. The positioning plate forms a first locking position and a second locking position. When encountering external force, the torch head slides from the first locking position into the second locking position and contacts the contact part on the positioning plate to generate an electrical signal. This process requires overcoming the resistance at the connection between the first and second locking positions, improving the accuracy of signal acquisition when the torch head and workpiece come into contact, increasing work efficiency, and simplifying the structure.

[0050] 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, 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.

[0051] Before providing a further detailed description of the embodiments of this utility model, the directional terms used in the embodiments of this utility model, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the scope of protection of this utility model.

[0052] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0053] like Figures 1 to 4 As shown, one embodiment of this utility model provides a welding torch for an automated welding machine. The automated welding machine 200 includes a controller 260, and the welding torch 100 is electrically connected to the controller 260. The welding torch 100 includes:

[0054] Welding torch body 110;

[0055] The protector 120 is sleeved on the welding torch body 110 and is fixedly connected to the welding torch body 110. The protector 120 is also electrically connected to the controller 260.

[0056] The gun head 130 is located below the welding gun body 110, and the gun head 130 is engaged with the protector 120.

[0057] Among them, such as Figure 1 As shown, the automated welding machine 200 includes a controller 260, a welding torch 100 electrically connected to the controller 260, the welding torch 100 includes a welding torch body 110, a torch head 130 sleeved on the welding torch body 110, the welding torch 100 also includes a protector 120 sleeved on the welding torch body 110, and part of the torch head 130 is snapped into connection with the protector 120, the protector 120 is also electrically connected to the controller 260. When the welding torch 100 is working normally, the protector 120 does not generate an electrical signal. When the welding torch 100 interferes with the workpiece, the torch head 130 is pressed against the workpiece, creating pressure. This pressure pushes the torch head 130 to move within the welding torch body 110 and the protector 120 until the position where the torch head 130 moves triggers the protector 120, generating an electrical signal. This electrical signal is then transmitted to the controller 260. Upon receiving the electrical signal, the controller 260 controls the automated welding machine 200 to stop working, preventing the torch head 130 from continuing to press against the workpiece and causing damage. This improves the service life of the welding torch 100 and the workpiece, and effectively avoids various further damages caused by collisions.

[0058] Specifically, the protector 120 includes a first latching position 123 and a second latching position 124. When the gun head 130 latches with the second latching position 124, the gun head 130 and the protector 120 form an electrical signal. The electrical signal is transmitted to the controller 260 through the protector 120, and the controller 260 controls the automated welding machine 200 to stop working.

[0059] It should be noted that when the welding torch 100 is working normally and does not collide with the workpiece, the torch head 130 does not move and remains within the first locking position 123. When the torch head 130 of the welding torch 100 collides with the workpiece, the contact force gradually increases during the fixed position of the workpiece and the movement of the welding torch 100. This causes the workpiece to push the torch head 130 to move on the welding torch body 110, and then from the first locking position 123 of the protector 120 into the second locking position 124. After part of the torch head 130 enters the second locking position 124, the torch head 130 and the protector 120 form an electrical signal, which is transmitted to the controller 260 through the wire. When the controller 260 receives this signal, it knows that the welding torch 100 has collided with the workpiece. The controller 260 can promptly control the automated welding machine 200 to stop working, and the welding torch 100 will no longer move continuously, avoiding continuous contact between the torch head 130 and the workpiece, thereby avoiding damage to the torch head 130 and the workpiece.

[0060] In one feasible implementation, such as Figure 2 and Figure 3 As shown, the protector 120 includes:

[0061] The mounting ring 121 is fitted onto the welding torch body 110, and the mounting ring 121 is fixedly connected to the welding torch body 110.

[0062] The positioning piece 122 is disposed on the side of the mounting ring 121 facing the welding gun body 110. The positioning piece 122 includes a first locking position 123 and a second locking position 124.

[0063] When the welding torch 100 is working normally, the torch head 130 is engaged with the first locking position 123. When the welding torch 100 encounters an obstacle, the torch head 130 is engaged with the second locking position 124.

[0064] The mounting ring 121 enables simultaneous connection of the welding torch body 110 and the torch head 130. Since the mounting ring 121 is fitted over both the welding torch body 110 and the torch head 130, the torch head 130 can move within the mounting ring 121 as it moves on the welding torch body 110. A positioning piece 122 is provided on the side of the mounting ring 121 facing the welding torch body 110, forming a first locking position 123 and a second locking position 124. When the torch head 130 encounters external force, it can slide from the first locking position 123 into the second locking position 124. The second locking position 124 of the positioning piece 122 is connected to the controller 260 via a wire, transmitting the electrical signal acquired by the positioning piece 122 to the controller 260. The controller 260 receives the electrical signal, i.e., the torch head 130 collision signal, and controls the automated welding machine 200 to stop working, preventing further external force from being applied to the torch head 130 and the workpiece.

[0065] It should be noted that the positioning piece 122 forms a first locking position 123 and a second locking position 124. When an external force is encountered, the gun head 130 slides from the first locking position 123 into the second locking position 124 and makes contact with the contact part 1223 on the positioning piece 122 to form an electrical signal. This process requires overcoming the resistance at the connection between the first locking position 123 and the second locking position 124 to improve the accuracy of signal acquisition when the gun head 130 and the workpiece come into contact, thereby improving work efficiency and making the structure simpler.

[0066] In one possible implementation, the protector 120 further includes:

[0067] Abutting blocks 125 are evenly arranged on the side of the mounting ring 121 facing the welding gun body 110, and a positioning piece 122 is provided between two adjacent abutting blocks 125.

[0068] Typically, the torch tip 130 is fitted onto the torch body 110. The mounting ring 121 needs to be connected to both the torch body 110 and the torch tip 130. Therefore, an abutment block 125 is provided at the step formed by the torch tip 130 and the torch body 110. This allows the mounting ring 121 to abut against the torch body 110 when it is engaged with the torch tip 130, thus improving the feasibility of connecting the mounting ring 121 to both the torch tip 130 and the torch body 110 simultaneously.

[0069] Specifically, the mounting ring 121 and the abutment block 125 are provided with countersunk holes 126, and bolts are threaded into the countersunk holes 126. The mounting ring 121 and the welding torch body 110 are connected by bolts.

[0070] Specifically, a countersunk hole 126 is provided at the corresponding position of the abutment block 125 and the mounting ring 121. An internal thread is provided within the countersunk hole 126. Simultaneously, a threaded blind hole is provided on the outer wall of the welding torch body 110, aligned with the countersunk hole 126. A bolt is used to pass through the countersunk hole 126 and the threaded blind hole, thus achieving a fixed connection between the protector 120 and the welding torch body 110. The multiple abutment blocks 125 increase the contact area between the mounting ring 121 and the welding torch body 110, improving the reliability of the fixed connection.

[0071] In one feasible implementation, the positioning piece 122 includes:

[0072] A pair of first C-shaped snap-fit ​​portions 1221 are made of insulating material, forming a first snap-fit ​​position 123;

[0073] A pair of second C-shaped snap-fit ​​portions 1222 are made of insulating material and are located at one end of a pair of first C-shaped snap-fit ​​portions 1221. The pair of second C-shaped snap-fit ​​portions 1222 form a second snap-fit ​​position 124.

[0074] Contact portion 1223 is configured at one end of a pair of second C-shaped latching portions 1222 that is away from a pair of first C-shaped latching portions 1221;

[0075] The connecting part 1224 is disposed at the end of the first C-shaped snap-fit ​​part 1221 away from the second C-shaped snap-fit ​​part 1222. The connecting part 1224 is used to connect the first C-shaped snap-fit ​​part 1221 and the abutment block 125.

[0076] Among them, such as Figure 3 and Figure 4As shown, the slots of a pair of first C-shaped latching portions 1221 are arranged opposite each other, thus forming a first latching position 123. Similarly, the slots of a pair of second C-shaped latching portions 1222 are arranged opposite each other, forming a second latching position 124. Due to the C-shape, the dimensions of the first latching position 123 and the second latching position 124 are larger than the connection points of the pair of first C-shaped latching portions 1221 and the pair of second C-shaped latching portions 1222. This arrangement ensures that when the welding torch 100 is working normally, the torch head 130 will always be located within the first latching position 123. Only under the action of external force, after overcoming the resistance at the connection points of the pair of first C-shaped latching portions 1221 and the pair of second C-shaped latching portions 1222, can it enter the second latching position 124 to generate an electrical signal.

[0077] It should be noted that the ends of the pair of second C-shaped latches 1222 that are away from the pair of first C-shaped latches 1221 are connected by contact portions 1223. This has a certain limiting effect on the movement position of the gun head 130. That is to say, under the action of external force, the final position of the gun head 130 is to abut against the contact portion 1223. Therefore, by electrically connecting the contact portion 1223 to the terminal 127, the electrical signal can be transmitted.

[0078] In order to prevent the gun head 130 from moving under the action of external force and causing deformation of the first locking position 123 and the second locking position 124, a pair of first C-shaped locking parts 1221, a pair of second C-shaped locking parts 1222 and contact parts 1223 are fixedly connected to the mounting ring 121, and are also connected to the abutment block 125 through the connecting part 1224, so as to further improve the stability of the positioning piece 122.

[0079] It is understandable that since both the first C-shaped latching parts 1221 and the second C-shaped latching parts 1222 are made of insulating material, the contact part 1223 is made of metal, and similarly, the latching connector 134 is made of metal. Thus, the circuit will not be conductive when the latching connector 134 is in the first latching position 123, and similarly, the circuit will not be conductive when the latching connector 134 first enters the second latching position 124, until the latching connector 134 contacts the contact part 1223, at which point the circuit is conductive and an electrical signal is generated. Furthermore, to prevent the mounting ring 121, positioning piece 122, and wiring terminal 127 from being too close to the heating end of the nozzle 130, which could affect the normal operation of the protector 120, the length of the nozzle 130 can be increased, ensuring that the distance between the protector 120 and the heating section of the nozzle 130 is within a safe range.

[0080] Furthermore, a terminal block 127 is provided on the side of the mounting ring 121 opposite to the welding torch body 110. One end of the terminal block 127 is electrically connected to the contact part 1223, and the other end of the terminal block 127 is electrically connected to the controller 260. By setting the terminal block 127 so that one end of the terminal block 127 is electrically connected to the contact part 1223 and the other end is electrically connected to the controller 260, when part of the torch tip 130 touches the contact part 1223, an electrical signal is generated and transmitted sequentially to the terminal block 127 and the controller 260 through wires. After receiving the electrical signal, the controller 260 controls the automated welding machine 200 to stop working, ensuring the safety and service life of the welding torch 100.

[0081] In one feasible implementation, the gun head 130 includes:

[0082] Gun head body 131;

[0083] Insert plate 132 is disposed on the side of the gun head body 131 facing the welding gun body 110;

[0084] The insertion rod 133 is located at the end of the insertion plate 132 away from the gun head body 131;

[0085] The snap connector 134 is located on the side of the insert rod 133 away from the insert plate 132. The snap connector 134 is matched with the first snap position 123, or the snap connector 134 is matched with the second snap position 124.

[0086] The gun head 130 is located on the side of the mounting ring 121 facing the welding gun body 110, and the gun head 130 is sleeved on the welding gun body 110.

[0087] It should be noted that by sequentially arranging the insert plate 132, insert rod 133, and snap-fit ​​connector 134 on the gun head body 131, when the snap-fit ​​connector 134 is engaged in the first snap-fit ​​position 123, part of the insert rod 133 is still outside the positioning piece 122. When the snap-fit ​​connector 134 enters the second snap-fit ​​position 124 and abuts against the contact part 1223, the insert rod 133 is completely engaged in the positioning piece 122. In this way, by simultaneously arranging the insert plate 132 and the contact part 1223, the snap-fit ​​connector 134 can be limited.

[0088] Furthermore, the gun head 130 includes multiple insert plates 132, with adjacent insert plates 132 forming positioning grooves 135. Since multiple abutment blocks 125 are provided within the mounting ring 121, the positioning grooves 135 formed by adjacent insert plates 132 must match the abutment blocks 125, thus limiting the circumferential movement of the gun head 130 and improving the reliability and stability of the connection between the protector 120 and the welding torch body 110 and the gun head 130. It should be noted that this embodiment provides four abutment blocks 125 and four positioning plates 122; correspondingly, the gun head 130 is provided with four insert plates 132, four insert rods 133, and four locking connectors 134.

[0089] Overall, such as Figures 1 to 4 As shown, the positioning piece 122 includes a first C-shaped snap-fit ​​portion 1221 and a second C-shaped snap-fit ​​portion 1222. The first C-shaped snap-fit ​​portion 1221 and the second C-shaped snap-fit ​​portion 1222 are fixedly connected to each other and are used to position and snap-fit ​​the snap-fit ​​connector 134. Both sides of the pair of first C-shaped snap-fit ​​portions 1221 are fixedly connected to connecting portions 1224, and the end of the connecting portion 1224 away from the first C-shaped snap-fit ​​portion 1221 is fixedly connected to one side of the abutment block 125. The upper part of the pair of second C-shaped snap-fit ​​portions 1222 is closed by the contact portion 1223. The contact part 1223 is electrically connected to one end of the terminal 127 via a wire. This allows the snap-fit ​​connector 134 to snap into the second snap-fit ​​position 124 formed by the second C-shaped snap-fit ​​part 1222 after it has snapped into the first snap-fit ​​position 123 formed by the first C-shaped snap-fit ​​part 1221. After the snap-fit ​​connector 134 comes into contact with the contact part 1223, it generates an electrical signal, which is then transmitted to the terminal 127 via the wire and sent to the controller 260. This facilitates the emergency stop of the entire automated welding machine 200. Multiple insert plates 132 are fixedly connected to the upper end of the gun head body 131. Insert rods 133 are fixedly connected to the insert plates 132. Clamping heads 134 are fixedly connected to the insert rods 133. The insert plates 132 are located between two adjacent abutment blocks 125 and below the positioning piece 122. The clamping heads 134 are clamped in a pair of first C-shaped clamping parts 1221. When the pressure between the gun head 130 and the workpiece increases, the gun head 130 moves under the force, driving the insert plates 132 and insert rods 133 to move synchronously, so that the clamping heads 134 are clamped from a pair of first C-shaped clamping parts 1221 into a pair of second C-shaped clamping parts 1222 and abut against the contact part 1223, thereby realizing the conduction of the electrical signal circuit, so that the controller 260 determines that the gun head 130 hits the workpiece and controls the automated welding machine 200 to stop working.

[0090] like Figure 5 As shown, another embodiment of this utility model provides an automated welding machine, the automated welding machine 200 comprising:

[0091] As mentioned above, the welding torch 100 includes a welding torch body 110 and a protector 120.

[0092] Column 210;

[0093] Z-axis electric lift 220 is mounted on column 210;

[0094] The Y-axis electric traverse device 230 is mounted on the Z-axis electric lift device 220;

[0095] The gun holder 240 is located at one end of the Y-axis electric transverse mover 230, and the welding gun body 110 is fixedly connected to the gun holder 240.

[0096] The main unit 250 is electrically connected to the Z-axis electric lift 220 and the Y-axis electric transverse mover 230 respectively;

[0097] The controller 260 is electrically connected to the host 250 and the protector 120 respectively.

[0098] The automated welding machine 200 includes a column 210, a controller 260, and a main unit 250. The main unit 250 is electrically connected to the controller 260 via wires. A Z-axis electric lifter 220 is fixedly connected to one side of the column 210. A Y-axis electric transverse traverse 230 is slidably connected to one side of the Z-axis electric lifter 220. A gun holder 240 is fixedly connected to one end of the Y-axis electric transverse traverse 230. A welding gun 100 is fixedly connected to the gun holder 240. The welding gun 100 includes a welding gun body 110 and a gun head 130, as well as a protector 120 that is sleeved on the outside of the welding gun body 110 and the gun head 130. The protector 120 includes a mounting ring 121. Multiple abutment blocks 125 are axially fixedly connected to the inner side of the mounting ring 121. A positioning piece 122 is fixedly connected between two adjacent abutment blocks 125. The lower end of the mounting ring 121 is inserted and connected to the gun head 130, and the gun head 130 is also sleeved on the outside of the welding gun body 110.

[0099] When the automated welding machine 200 moves the welding torch 100, the torch head 130 is initially in the working position, that is, in the first locking position 123 formed by the positioning piece 122. When the torch head 130 collides with the workpiece, under the action of external force, in conjunction with the shape of the positioning piece 122, the torch head 130 moves towards the welding torch body 110, and then moves from the first locking position 123 on the positioning piece 122 to the second locking position 124, and abuts against the contact part 1223, forming an electrical signal. The contact part 1223 is electrically connected to the wiring terminal 127 outside the mounting ring 121 through a wire. At the same time, the output end of the wiring terminal 127 is also electrically connected to the controller 260. In this way, the electrical signal is transmitted to the controller 260 through the wiring terminal 127. After receiving the electrical signal, the controller 260 knows that the torch head 130 is interfering with the workpiece, and then controls the automated welding machine 200 to stop working to avoid further damage to the workpiece and the torch head 130 caused by the gradual increase of the contact force.

[0100] It is understood that since the automated welding machine 200 of this application includes the welding torch 100 described above, it possesses all the advantages of the welding torch 100, and will not be elaborated further. Simultaneously, an X-axis electric transverse actuator can be installed on the automated welding machine 200 to expand the movement range of the welding torch 100, which is a conventional method in the art and will not be elaborated further.
