Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a welding device with a workpiece locking effect. Background Art

[0002] The workpiece refers to the object to be processed during the machining process. During the machining process, in order to connect two workpieces together, it is usually necessary to use a welding device to process the workpiece. In order to ensure the accuracy, stability and high quality of the welding, the workpiece needs to be fixed during the welding process.

[0003] The Chinese patent "A workpiece welding device with positioning function" authorization announcement number "CN211840516U" can facilitate the positioning and fixing of the workpiece according to the welding requirements during the workpiece welding process by setting a clamp, a fixing spring, a fixing plate, a fixing rod, a non-slip pad and a scale layer, thereby avoiding the problem of misalignment between the workpieces and improving the welding effect of the workpiece.

[0004] In the above scheme, the cylindrical workpiece is fixed by rotating the fixing rod, but when fixing a single cylindrical workpiece, it is necessary to rotate the two fixing rods separately, which is cumbersome to operate. Moreover, when the two fixing rods are rotated separately to drive the corresponding springs and the fixing plates to fix the workpiece, it is impossible to ensure that the workpiece is fixed in the center, which will result in unsatisfactory docking effect between the workpieces, thereby affecting the welding quality.

[0005] Therefore, a welding device with a workpiece locking effect is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a welding device with a workpiece locking effect in order to solve the above-mentioned problem, thereby improving the problem that when fixing a single cylindrical workpiece, two fixing rods need to be rotated separately, the operation is relatively cumbersome, and when the two fixing rods are rotated separately to drive the corresponding springs and fixing plates to fix the workpiece, it is impossible to ensure that the workpiece is fixed in the center, which will lead to an unsatisfactory docking effect between the workpieces, thereby affecting the welding quality.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a welding device with a workpiece locking effect, comprising: a base, a welding gun is arranged on the top of the base; a fixing mechanism, which is used to realize centering fixation of the workpiece during welding, and the fixing mechanism is arranged on the top of the base; wherein the fixing mechanism comprises two mounting plates fixedly connected to the top of the base, the inner wall of the mounting plate is rotatably connected to an air storage ring, the inner wall of the air storage ring is slidably connected to an extrusion plate, one end of the air storage ring is rotatably connected to a threaded sleeve, one end of the threaded sleeve penetrates into the interior of the air storage ring, the inner wall of the threaded sleeve is threadedly connected to a threaded rod, one end of the threaded rod penetrates out of the threaded sleeve and is rotatably connected to one end of the extrusion plate, and a fixing component is arranged on the inner side of the air storage ring.

[0008] Preferably, the fixing assembly includes a fixing ring fixedly connected to the inner wall of the gas storage ring, the surface of the fixing ring is fixedly connected with cylinders distributed in an annular shape, one end of the cylinder passes through the inner side of the fixing ring, a connecting pipe is provided between the cylinder and the gas storage ring, the inner wall of the cylinder is slidably connected with a piston rod, one end of the piston rod passes through the cylinder and is fixedly connected with a fixing plate. Driving the gas in the gas storage ring to enter multiple cylinders at the same time is conducive to enabling multiple piston rods to push the corresponding fixing plates to move toward the center point of the fixing ring at the same time, thereby completing the centering of the workpiece. Therefore, when fixing the workpiece, it is only necessary to rotate the threaded sleeve to center the workpiece, which is simple to operate. At the same time, centering the two workpieces is conducive to ensuring the docking effect of the two workpieces during welding, thereby improving the welding quality of the workpieces.

[0009] Preferably, a contact pad is fixedly connected to the inner wall of the fixing plate, and the contact pad is a rubber component, thereby enhancing the stability of the fixing plate in fixing the workpiece.

[0010] Preferably, the surface of the contact pad is provided with grooves distributed in equal rows, and the grooves are opened longitudinally, which is beneficial to increase the friction between the workpiece and the fixed plate when the gas storage ring drives the workpiece to rotate, and improves the stability of the workpiece during rotation.

[0011] Preferably, a spring is sleeved on the surface of the piston rod, one end of the spring is fixedly connected to the inner wall of the cylinder, and the other end of the spring is fixedly connected to one end of the piston rod. When the workpiece is released, the spring can help to drive the fixing plate to reset, and the gas entering the cylinder can flow back to the gas storage ring, which is conducive to the repeated use of the device.

[0012] Preferably, the surfaces of the two gas storage rings are fixedly connected with gear rings, the surfaces of the gear rings are meshedly connected with gears, one end of one of the gears is fixedly connected with a round rod, the other end of the round rod passes through two mounting plates in sequence and is fixedly connected with one end of another gear. Under the action of the two gears and the two gear rings, it is conducive to driving the two workpieces to rotate synchronously during the welding process, reducing the difficulty of operation during welding and increasing the practicality of the device.

[0013] Preferably, one end of the extrusion plate is fixedly connected to a limiting rod, and the other end of the limiting rod passes through the gas storage ring. When the threaded rod pushes the extrusion plate, the limiting rod helps to ensure the stability of the movement of the extrusion plate.

[0014] Preferably, the middle portion of the fixing plate is curved in an arc shape, which is conducive to better fitting with the surface of the cylindrical workpiece.

[0015] The beneficial effects of the utility model are:

[0016] 1. When fixing the workpiece, the interaction between the threaded sleeve and the threaded rod drives the gas in the gas storage ring to enter multiple cylinders at the same time, which is conducive to enabling multiple piston rods to push the corresponding fixing plates to move toward the center point of the fixing ring at the same time, thereby completing the centering of the workpiece. Therefore, when fixing the workpiece, only the threaded sleeve needs to be rotated to center the workpiece, which is simple to operate. At the same time, centering the two workpieces is conducive to ensuring the docking effect of the two workpieces during welding, thereby improving the welding quality of the workpieces;

[0017] 2. Under the action of two gears and two gear rings, it is helpful to drive the two workpieces to rotate synchronously during the welding process, which reduces the difficulty of operation during welding and increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4 As shown, a welding device with a workpiece locking effect comprises: a base 1, a welding gun 2 is arranged at the top of the base 1; a fixing mechanism 3, which is arranged at the top of the base 1 for realizing centering fixation of the workpiece during welding; wherein the fixing mechanism 3 comprises two mounting plates 301 fixedly connected to the top of the base 1, an air storage ring 302 is rotatably connected to the inner wall of the mounting plate 301, an extrusion plate 303 is slidably connected to the inner wall of the air storage ring 302, a threaded sleeve 304 is rotatably connected to one end of the air storage ring 302, one end of the threaded sleeve 304 penetrates into the interior of the air storage ring 302, a threaded rod 305 is threadedly connected to the inner wall of the threaded sleeve 304, one end of the threaded rod 305 penetrates out of the threaded sleeve 304 and is rotatably connected to one end of the extrusion plate 303, and a fixing component 306 is arranged on the inner side of the air storage ring 302.

[0025] A slide groove is provided at the top of the base 1, and a bolt is rotatably connected to the inner wall of the slide groove. A slider is threadedly connected to the surface of the bolt, and a support rod is fixedly connected to the top of the slider. The welding gun 2 is fixed to the top of the support rod. The distance between the welding gun 2 and the workpiece can be adjusted by rotating the bolt. The welding gun 2 is set between the two mounting plates 301.

[0026] It should be noted that the welding gun 2 in the above description is a device with relatively mature application in the prior art, which refers to the part that performs the welding operation during the welding process and is a tool used for gas welding.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the fixing assembly 306 includes a fixing ring 3061 fixedly connected to the inner wall of the gas storage ring 302, a cylinder 3062 distributed in an annular shape is fixedly connected to the surface of the fixing ring 3061, one end of the cylinder 3062 penetrates to the inner side of the fixing ring 3061, a connecting pipe 3063 is arranged between the cylinder 3062 and the gas storage ring 302, a piston rod 3064 is slidably connected to the inner wall of the cylinder 3062, one end of the piston rod 3064 penetrates out of the cylinder 3062 and is fixedly connected to a fixing plate 3065. The middle part of the fixing plate 3065 is bent in an arc shape.

[0028] When welding the workpieces, one end of the two workpieces is inserted from the ends of the two gas storage rings 302 that are away from each other. At this time, the workpieces are placed between multiple fixed plates 3065, and the workpieces are moved horizontally so that one end of the two workpieces are in contact, and the contact position of the two workpieces is in the same vertical plane with the nozzle of the welding gun 2.

[0029] After placement is completed, rotating the threaded sleeve 304 drives the threaded rod 305 to rotate, thereby pushing the extrusion plate 303 to move. Gas is stored in the gas storage ring 302. When the extrusion plate 303 moves, it will squeeze the gas in the gas storage ring 302, and the squeezed gas will enter multiple connecting tubes 3063 at the same time, and enter the corresponding cylinders 3062 through multiple connecting tubes 3063 at the same time. When the gas enters the cylinder 3062, it will push the piston rod 3064 to move and push the fixed plate 3065 to move. There are four fixed plates 3065, and the fixed plates 3065 are distributed in a circular shape. When the gas enters four cylinders 3062 at the same time, it will drive the four fixed plates 3065 to move at the same time to fix the cylindrical workpiece. Since the moving directions of the four fixed plates 3065 are all toward the center of the fixed ring 3061, the four fixed plates 3065 move at the same time to achieve center fixation of the cylindrical workpiece.

[0030] like Figure 4 As shown, the inner wall of the fixing plate 3065 is fixedly connected with a contact pad 3067, which is a rubber component. The surface of the contact pad 3067 is provided with grooves 3068 distributed in equal rows, and the grooves 3068 are opened in the longitudinal direction. When the fixing plate 3065 fixes the workpiece, the surface of the contact pad 3067 contacts the surface of the workpiece.

[0031] like Figure 4 As shown, a spring 3066 is sleeved on the surface of the piston rod 3064 , one end of the spring 3066 is fixedly connected to the inner wall of the cylinder 3062 , and the other end of the spring 3066 is fixedly connected to one end of the piston rod 3064 .

[0032] When the gas enters the cylinder 3062 and pushes the piston rod 3064, the spring 3066 will be squeezed. When the workpiece is welded and released, the threaded sleeve 304 is rotated in the reverse direction, and the threaded rod 305 drives the extrusion plate 303 to move in the reverse direction. At this time, the gas in the gas storage ring 302 loses its squeezing, and under the action of the spring 3066, the gas in the cylinder 3062 will flow back into the gas storage ring 302. At this time, the fixing plate 3065 moves in the reverse direction to release the fixation of the workpiece.

[0033] like Figure 2 As shown, the surfaces of the two air storage rings 302 are fixedly connected with gear rings 307, and the surfaces of the gear rings 307 are meshingly connected with gears 3071, one end of one of the gears 3071 is fixedly connected with a round rod 3072, and the other end of the round rod 3072 passes through the two mounting plates 301 in sequence and is fixedly connected to one end of the other gear 3071.

[0034] The other end of one of the gears 3071 is fixedly connected with a torque. When the workpiece needs to be welded after being fixed, one of the gears 3071 is rotated, and the other gear 3071 is driven to rotate under the action of the round rod 3072. At this time, the two gears 3071 rotate at the same time and drive the corresponding gear rings 307 to rotate at the same time, so that the two air storage rings 302 drive the two workpieces to rotate at the same time. At this time, the staff can start the welding gun 2 to weld the workpiece.

[0035] like Figure 3 As shown, one end of the extrusion plate 303 is fixedly connected to a limit rod 308, and the other end of the limit rod 308 passes through the gas storage ring 302. The surface of the limit rod 308 is slidably connected to the inner wall of the gas storage ring 302, and when the extrusion plate 303 moves, the limit rod 308 is driven to move synchronously.

[0036] When the utility model is in use, when welding workpieces, two workpieces are respectively inserted into the two gas storage rings 302, and the workpieces are moved horizontally so that one end of the two workpieces are in contact, and the contact position of the two workpieces is in the same vertical plane with the nozzle of the welding gun 2. After placement, the threaded sleeve 304 is rotated to drive the threaded rod 305 to rotate, thereby pushing the extrusion plate 303 to move and squeeze the gas in the gas storage ring 302. The squeezed gas will enter the multiple connecting pipes 3063 at the same time, and enter the corresponding cylinder 3062 through the multiple connecting pipes 3063 at the same time. When the gas enters the cylinder 3062, it will push the piston rod 3064 to move and push the fixing plate 3065 to move. At this time, the four fixing plates 3065 move at the same time to fix the cylindrical workpiece in the center. After the fixing is completed, the distance between the welding gun 2 and the workpiece is adjusted, and one of the gears 3071 is rotated to drive the other gear 3071 to rotate. At this time, under the action of the fixing mechanism 3, the two gear rings 307 will drive the two workpieces to rotate at the same time. At this time, the staff starts the welding gun 2 to weld the workpieces.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
