Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding equipment with a protection function. Background Technique

[0002] Welding equipment is a tool or machine used for welding operations. It consists of a welding power source, a welding gun or a welding head, etc. Common welding equipment includes arc welding machines, gas shielded welding machines, laser welding machines, plasma welding machines, etc. These equipment can be selected according to welding requirements, such as welding materials, welding positions, welding strength requirements, etc. The main function of welding equipment is to provide electrical energy, heat energy or laser energy to heat and melt the welded parts and filler materials to achieve a welded connection. Different welding equipment uses different energy sources and welding methods, and is suitable for different welding materials and welding requirements.

[0003] When butt-welding existing columnar or tubular mechanical fittings, most welding equipment fixes two groups of fittings separately, but fixing them separately easily leads to axis deviation, which in turn causes the welding points to deviate or the thickness to vary, thus posing a safety hazard during use. Moreover, there is no protection for the staff during welding, and the splashing welding slag can still harm the staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding equipment with a protection function to solve the problems raised in the above background technique.

[0006] A sliding plate, the sliding plate penetrates the machine body and is slidably connected to the machine body. The side of the sliding plate close to the cylinder is fixedly connected to the output shaft of the cylinder. When the cylinder is started, the cylinder will drive the fixed ring to move towards the direction close to the resisting ring through the sliding plate and the machine case. At the same time, the fixed ring will drive the positioning box to move together. A machine case is fixedly connected to the surface of the sliding plate, a fixed ring is fixedly connected to the side of the machine case away from the sliding plate, through holes are formed in the surface of the fixed ring, a motor is fixedly connected to the inner wall of the machine case, and the output shaft of the motor penetrates and is fixedly connected to a small gear. When the motor is started, the transmission gear will drive the entire positioning box to rotate;

[0007] Positioning box, the positioning box penetrates through the fixing ring and is rotationally connected. An annular groove is formed on the surface of the positioning box, and a transmission gear is fixedly connected to the inner side of the annular groove. The transmission gear meshes with a small gear. A square groove is formed on the surface of the positioning box, and an inclined block is slidably connected to the inner side of the square groove. A positioning block is fixedly connected to the left side of the inclined block.

[0008] Preferably, the number of the positioning blocks is three groups, and the three groups of positioning blocks are respectively arranged in a circumferential array with the center line of the positioning box as the axis. An arc-shaped rod penetrates through every two groups of positioning blocks, and an arc-shaped spring is fixedly connected between every two groups of positioning blocks. The three groups of positioning blocks are contracted towards the middle through the arc-shaped rod, so as to position the mechanical fittings to be butt-welded.

[0009] Preferably, a push rod penetrates through the surface of the positioning block. The push rod penetrates through the positioning box and is slidably connected. A circular ring is fixedly connected to the end of the push rod away from the positioning block. A short spring is fixedly connected between the circular ring and the surface of the positioning box. After welding is completed, the air cylinder is started again, so that the circular ring abuts against the surface of the abutting plate, so that the hinged plate is no longer clamped with the card slot.

[0010] Preferably, a cavity is formed inside the positioning block, and a chute, a card slot and a limiting slot are formed inside the cavity. When the positioning block contracts towards the middle, since the push rod penetrates through the positioning box, the push rod slides relatively along the chute during the contraction process of the positioning block.

[0011] Preferably, a slider is slidably connected to the inner side of the limiting slot. A support rod is fixedly connected to the surface of the slider. The support rod penetrates through and is rotationally connected with a rocker. The left side of the rocker is fixedly connected to the right side of the push rod.

A torsion spring is fixedly connected between the hinged plate and the rocker.

[0012] Preferably, the number of the positioning parts is two groups, and the two groups of positioning parts are symmetrically arranged with the center line of the machine body as the axis of symmetry. Through the positioning block and the arc-shaped rod, it can be ensured that during the butt-welding process of two groups of columnar or tubular mechanical fittings, they can be positioned while keeping the axes aligned, preventing welding deviation from causing potential safety hazards during use.

After positioning, the cylinder is started again to drive the two sets of mechanical accessories in the positioning boxes to fit in the middle position inside the body, and then welding is performed through the welding gun. Through the positioning block and the arc rod, the two sets of columnar or tubular mechanical accessories can be positioned while keeping the axis aligned during the welding process, preventing welding deviation from causing safety hazards during use.

[0025] As Figures 1-8 As shown in the figure, the present utility model provides a technical solution: a welding device with a protection function, including a machine body 1, a fixed block 3 is fixedly connected to the surface of the machine body 1, a cylinder 4 is fixedly connected to the surface of the fixed block 3, a welding gun 5, a contact plate 6 and a contact ring 7 are fixedly connected to the inner wall of the machine body 1, and a positioning part 2 is arranged inside the machine body 1. The positioning part 2 includes: a slide plate 21, a chassis 22, a fixed ring 23, a through hole 24, a motor 25, a small gear 26, a positioning box 27, an annular groove 28, a transmission tooth 29, a square groove 210, a positioning block 211, an inclined plane block 212, an arc-shaped rod 213, an arc-shaped spring 214, a push rod 215, a ring 216, a short spring 217, a card slot 218, a limit slot 219, a slide block 220, a support rod 221, a lever 222, a hinge plate 223, a limit block 224, a torsion spring 225, a cavity 226, and a slide groove 227.

[0026] The sliding plate 21 penetrates through the body 1, and the sliding plate 21 is slidably connected to the body 1. One side of the sliding plate 21 close to the air cylinder 4 is fixedly connected to the output shaft of the air cylinder 4. The columnar or tubular mechanical fittings to be butt-welded are passed through the abutting ring 7 and the abutting plate 6 and inserted into the body 1. The air cylinder 4 is started, and the air cylinder 4 will drive the fixing ring 23 to move towards the direction close to the abutting ring 7 through the sliding plate 21 and the chassis 22. At the same time, the fixing ring 23 will drive the positioning box 27 to move together. The surface of the sliding plate 21 is fixedly connected with the chassis 22. One side of the chassis 22 away from the sliding plate 21 is fixedly connected with the fixing ring 23. Through holes 24 are formed on the surface of the fixing ring 23. The inner wall of the chassis 22 is fixedly connected with a motor 25. The output shaft of the motor 25 penetrates through and is fixedly connected with a small gear 26. During the welding process, the motor 25 can be started. The output shaft of the motor 25 will drive the transmission gear 29 to rotate through the small gear 26, and the transmission gear 29 will drive the entire positioning box 27 to rotate, so that the tubular fittings to be positioned can be subjected to circular butt-welding stably and uniformly, making the welding effect more stable. The positioning box 27 penetrates through the fixing ring 23 and is rotatably connected. An annular groove 28 is formed on the surface of the positioning box 27. A transmission gear 29 is fixedly connected to the inner side of the annular groove 28. The transmission gear 29 meshes with the small gear 26. A square groove 210 is formed on the surface of the positioning box 27. An inclined block 212 is slidably connected to the inner side of the square groove 210. A positioning block 211 is fixedly connected to the left side of the inclined block 212. After the columnar or tubular mechanical fittings pass through the positioning box 27, as the inclined surface of the inclined block 212 gradually abuts against the inclined surface inside the abutting ring 7, the inclined block 212 will gradually slide along the square groove 210, and further the inclined block 212 will drive the positioning block 211 to move together. The number of the positioning blocks 211 is three groups, and the three groups of positioning blocks 211 are respectively arranged in a circumferential array with the center line of the positioning box 27 as the axis, and each two groups of positioning blocks 211 are penetrated by an arc-shaped rod 213. An arc-shaped spring 214 is fixedly connected between each two groups of positioning blocks 211. The three groups of positioning blocks 211 are contracted towards the middle through the arc-shaped rod 213, and at the same time the arc-shaped spring 214 is compressed, so as to position the mechanical fittings to be butt-welded. A push rod 215 penetrates through the surface of the positioning block 211. The push rod 215 penetrates through the positioning box 27 and is slidably connected. One end of the push rod 215 away from the positioning block 211 is fixedly connected with a circular ring 216. A short spring 217 is fixedly connected between the circular ring 216 and the surface of the positioning box 27. After the welding is completed, the air cylinder 4 is started again, so that the circular ring 216 abuts against the surface of the abutting plate 6, further the push rod 215 pushes the rocker 222, and the rocker 222 rotates around the support rod 221, so that the hinge plate 223 is no longer clamped with the card slot 218, and the compressed arc-shaped spring 214 will push the positioning block 211 to reset, and the butt-welded mechanical fittings can be taken out.A cavity 226 is formed inside the positioning block 211. A chute 227, a clamping groove 218, and a limiting groove 219 are formed on the inner side of the cavity 226. When the positioning block 211 contracts towards the middle, since the push rod 215 penetrates through the positioning box 27, the push rod 215 slides relatively along the chute 227 during the contraction of the positioning block 211. At the same time, the slider 220 moves relatively upward along the limiting groove 219, further causing the clamping groove 218 to abut against the hinge plate 223, causing the hinge plate 223 to rotate downward and also compressing the torsion spring 225. When the relative position of the hinge plate 223 moves to the upper clamping groove 218, the compressed torsion spring 225 will spring up the hinge plate 223 and embed it into the clamping groove 218, preventing the positioning block 211 from being pushed back by the compressed arc spring 214. A slider 220 is slidably connected to the inner side of the limiting groove 219. A support rod 221 is fixedly connected to the surface of the slider 220. The support rod 221 penetrates through and is rotatably connected to a rocker 222. The left side of the rocker 222 is fixedly connected to the right side of the push rod 215. A hinge plate 223 is hinged to the surface of the rocker 222. A limiting block 224 is fixedly connected to the surface of the rocker 222. A torsion spring 225 is fixedly connected between the hinge plate 223 and the rocker 222. The number of the positioning parts 2 is two groups, and the two groups of positioning parts 2 are symmetrically arranged with the center line of the machine body 1 as the axis of symmetry. Through the positioning block 211 and the arc rod 213, during the butt welding process of two columnar or tubular mechanical fittings, they can be positioned while keeping the axes aligned, preventing welding deviation from causing potential safety hazards during use.

[0027] Based on the above embodiment, the cylindrical or tubular mechanical accessories that need to be butt-welded are passed through the interference ring 7 and the interference plate 6 and inserted into the machine body 1, and the cylinder 4 is started. The cylinder 4 will drive the fixing ring 23 to move in the direction close to the interference ring 7 through the slide plate 21 and the chassis 22. At the same time, the fixing ring 23 will drive the positioning box 27 to move together. When the cylindrical or tubular mechanical accessories pass through the positioning box 27, as the inclined surface of the inclined surface block 212 gradually contacts the inclined surface inside the ring 7, the inclined surface block 212 will gradually slide along the square groove 210, thereby causing the inclined surface block 212 to drive the positioning block 211 to move together, and the three groups of positioning blocks 211 are retracted toward the middle through the arc rod 213. At the same time, the arc spring 214 is compressed, thereby positioning the mechanical accessories that need to be butt-welded. When the positioning block 211 retracts toward the middle, the push rod 215 penetrates the positioning box 27, thereby causing the push rod 215 to move relative to the positioning block 211 during the contraction process. When the hinge plate 223 moves to the upper slot 218, the compressed torsion spring 225 will bounce the hinge plate 223 and insert it into the slot 218, so that the positioning block 211 will not be pushed back by the compressed arc spring 214. After the positioning is completed, the cylinder 4 is started again, so that the cylinder 4 drives the mechanical parts of the two groups of positioning boxes 27 to fit in the middle position inside the machine body 1, and then the welding gun 5 is used to weld. Through the positioning block 211 and the arc rod 213, the two groups of columnar or tubular mechanical parts can be kept aligned and positioned during the welding process, thereby preventing the welding deviation from causing a safety hazard during use.

[0028] During the welding process, the motor 25 can be started, and the output shaft of the motor 25 will drive the transmission gear 29 to rotate through the pinion 26, and the transmission gear 29 will drive the entire positioning box 27 to rotate, so that the positioned tubular accessories can be annularly butt-welded stably and uniformly, making the welding effect more stable. After welding is completed, the cylinder 4 is started again to make the ring 216 contact the surface of the contact plate 6, further making the push rod 215 push the tilting rod 222, and making the tilting rod 222 rotate with the support rod 221, so that the hinge plate 223 is no longer clamped with the slot 218, and the compressed arc spring 214 will push the positioning block 211 to reset, and the mechanical accessories that have been butt-welded can be taken out.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
