Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding equipment, and in particular to a high-precision automatic welding machine based on shaft head anti-offset. Background Technology
[0002] Medium and large steel rollers are commonly used in various mechanical equipment. Due to their high strength, wear resistance and customizability, they are widely used in various industries.
[0003] In the steel roller processing, welding is an unavoidable production process, that is, assembly shafts are welded to both ends of the steel roller (workpiece).
[0004] Because steel rollers are heavy, they are usually fixed on a workbench, and the shaft ends are welded and assembled at both ends of the steel roller by driving a welding torch to move around the circumference of the steel roller.
[0005] However, during the process of moving the welding torch, welding offset or deviation can easily occur, which will reduce the welding accuracy of the workpiece. Utility Model Content
[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a high-precision automatic welding machine based on shaft head anti-deviation, which enables the steel roller to rotate while the welding torch remains stationary during the welding process, simultaneously positioning the assembled shaft head to prevent wobbling and deviation during rotation, thereby improving the welding accuracy of the workpiece.
[0007] A high-precision automatic welding machine based on shaft head anti-offset according to an embodiment of the present utility model includes:
[0008] Workbench;
[0009] A drive unit, mounted on the worktable, is used to support and drive the roller-shaped workpiece to rotate;
[0010] A positioning device is used to abut against the free end of an assembly shaft head pre-installed at the end of a roller-shaped workpiece to position the assembly shaft head.
[0011] A welding device, located on one side of the roller-shaped workpiece, is used to weld the connection between the roller-shaped workpiece and the assembly shaft head.
[0012] A high-precision automatic welding machine based on shaft head anti-offset according to an embodiment of the present invention has at least the following beneficial effects:
[0013] 1. This utility model uses a driving device to drive the roller workpiece to rotate, and in conjunction with a welding device in a fixed position, eliminates welding deviations caused by the movement of the welding device during the welding process, thus significantly improving welding accuracy.
[0014] 2. This utility model uses a positioning device to position the assembly shaft head by abutting against the free end of the assembly shaft head pre-installed at the end of the roller-shaped workpiece. It can be understood that when the roller-shaped workpiece rotates, it drives the assembly shaft head to rotate. The positioning device abuts against the free end of the assembly shaft head. On the one hand, the positioning device can axially limit the assembly shaft head to prevent axial displacement when the assembly shaft head rotates. On the other hand, when the assembly shaft head rotates, the contact between the positioning device and the free end of the assembly shaft head can generate frictional resistance. This frictional resistance of the positioning device against the assembly shaft head can prevent radial wobbling of the assembly shaft head when it rotates, thereby improving the welding accuracy of the workpiece.
[0015] According to some embodiments of the present invention, the driving device includes a support component and a power component. The support component includes two rollers arranged side by side, which cooperate to support the roller-shaped workpiece. The power component is used to drive one of the two rollers to rotate so that the roller drives the roller-shaped workpiece to rotate.
[0016] The advantages are: by using two rollers to support the roller-shaped workpiece, the double roller support structure forms a V-shaped stable support surface. Compared with single roller support, it can effectively reduce the radial runout of the roller-shaped workpiece during rotation, which is conducive to improving welding accuracy. In addition, the power component drives one of the two rollers to rotate, forming a drive configuration of active roller and driven roller, which ensures transmission efficiency and reduces energy consumption.
[0017] According to some embodiments of the present invention, the support assembly further includes a first mounting bracket, two rollers are rotatably mounted on the first mounting bracket, the worktable includes a table body and an adjusting guide rail mounted on the table body, the length direction of the adjusting guide rail is parallel to the length direction of the roller workpiece, the first mounting bracket is mounted on the adjusting guide rail, and the first mounting bracket can be adjusted and fixed on the adjusting guide rail.
[0018] The advantage of this invention is that by utilizing the position adjustment cooperation of the first mounting bracket and the adjusting guide rail, the position of the support component can be adjusted. Thus, the support position of the support component on the roller workpiece can be adjusted according to the length of the roller workpiece, thereby adapting to the welding processing of roller workpieces of different sizes.
[0019] According to some embodiments of the present invention, the positioning device includes a positioning sensor, which is used to abut against the free end of the assembly shaft head at one end of the positioning roller workpiece. The positioning sensor can detect whether the assembly shaft head is in position with the positioning sensor and energize the assembly shaft head.
[0020] The advantages are as follows: This utility model utilizes a positioning sensor to position the free end of the assembly shaft head at one end of the roller-shaped workpiece. This allows the positioning sensor to detect whether the assembly shaft head is in place with the positioning sensor and to energize the assembly shaft head while positioning it. On the one hand, the automatic detection of the positioning sensor replaces manual visual inspection, which helps to improve positioning efficiency and accuracy, and reduces the welding defect rate caused by abnormal positioning of the assembly shaft head by the positioning device. On the other hand, the positioning sensor also has the function of current transmission. After the controller of the automatic welding machine is turned on, the current is transmitted to the workpiece through the positioning sensor. After the welding torch senses that the workpiece is energized, the welding torch automatically ignites and welds, thereby achieving the effect of automatic welding.
[0021] According to some embodiments of the present invention, the positioning device further includes a first positioning member, which is movable along the axial direction of the roller-shaped workpiece. The first positioning member is used to abut against the end of the roller-shaped workpiece away from the positioning sensor, or to abut against the free end of the assembly shaft head pre-installed on the roller-shaped workpiece away from the positioning sensor.
[0022] The advantages are: by using the first positioning member to abut against the end of the positioning roller workpiece away from the positioning sensor, or by using the first positioning member to abut against the free end of the assembly shaft head pre-installed on the roller workpiece away from the positioning sensor, the first positioning member and the positioning sensor cooperate to form a bidirectional positioning structure, which helps to improve the positioning stability of the positioning device. In addition, the first positioning member can move along the axial direction of the roller workpiece, so that the first positioning member can press against or release the workpiece by moving, thereby facilitating the loading and unloading of the workpiece between the first positioning member and the positioning sensor.
[0023] According to some embodiments of the present invention, the positioning device further includes:
[0024] Two first adjustment mechanisms are disposed on the worktable, and the two first adjustment mechanisms are respectively used to adjust the height of the positioning sensor and the first positioning component;
[0025] The first adjustment mechanism includes a second mounting bracket, a first lifting seat that slides up and down on the second mounting bracket, and a first screw that drives the first lifting seat to rise and fall. The positioning sensor or the first positioning component is disposed on the first lifting seat.
[0026] The advantages are: by using two first adjustment mechanisms to adjust the height of the positioning sensor and the first positioning component respectively, the positioning device can adapt to the welding processing requirements of roller workpieces with different diameters. In addition, the first adjustment mechanism uses the first screw to drive the first lifting seat to rise and fall, so that the adjustment process of the first adjustment mechanism is smooth and vibration-free. At the same time, the threaded engagement between the first screw and the first lifting seat or between the first screw and the second mounting bracket can achieve self-locking, which makes it easy to lock the height of the first lifting seat.
[0027] According to some embodiments of the present invention, the welding device includes a second adjustment mechanism, a third adjustment mechanism, and a welding assembly. The third adjustment mechanism is disposed on the second adjustment mechanism, and the welding assembly is disposed on the third adjustment mechanism. One of the second adjustment mechanism and the third adjustment mechanism is used to adjust the height of the welding assembly, and the other of the second adjustment mechanism and the third adjustment mechanism is used to adjust the horizontal position of the welding assembly.
[0028] The advantages are: by using the second and third adjustment mechanisms to adjust the height and horizontal position of the welding components, the present invention can achieve precise adjustment of the welding position of the welding components to adapt to the welding requirements of roller workpieces of different sizes and assembly shaft heads, ensure the consistency of workpiece processing, and realize 360° automatic and precise welding processing of workpieces.
[0029] According to some embodiments of the present invention, the welding assembly includes a welding torch and a first cylinder, the first cylinder being disposed on the third adjustment mechanism, and the first cylinder being used to drive the welding torch closer to and away from the connection between the roller-shaped workpiece and the assembly shaft head.
[0030] The advantages of this invention are: by using a first cylinder to drive the welding torch to approach and move away from the connection between the roller-shaped workpiece and the assembly shaft, the welding torch can quickly approach and move away from the welding position, ensuring that when welding is required, the welding torch can quickly and smoothly contact the welding point for welding, and then quickly move away from the welding position after welding, avoiding the welding torch from obstructing the loading and unloading of the workpiece.
[0031] According to some embodiments of the present invention, the welding device further includes a turntable, the second adjustment mechanism is disposed on the turntable, the turntable is used to adjust the welding angle direction of the welding assembly, the turntable is provided with an arc-shaped groove that runs vertically through the turntable, the worktable is provided with a fixing bolt, the fixing bolt passes through the arc-shaped groove, and the fixing bolt is used to fix the turntable.

[0046] The following description, in conjunction with the accompanying drawings, describes a high-precision automatic welding machine based on shaft head anti-offset according to an embodiment of the present invention.
[0047] The present invention aims to provide an embodiment of a high-precision automatic welding machine based on shaft head anti-misalignment.
[0048] Reference Figure 1 In this embodiment, a high-precision automatic welding machine based on shaft head anti-offset mainly includes a worktable 100, a drive device, a positioning device, a welding device, and a controller.
[0049] This embodiment uses a controller to regulate the drive device, positioning device, and welding device to achieve the automatic welding function of the automatic welding machine.
[0050] The drive device is mounted on the worktable 100 and is used to support and drive the roller workpiece 110 to rotate.
[0051] In this embodiment, the roller workpiece 110 is driven to rotate by a driving device, which, together with the welding device in a fixed position, eliminates welding deviations caused by the movement of the welding device during the welding process, thus significantly improving welding accuracy.
[0052] Specifically, the driving device includes a support assembly 130 and a power assembly. The support assembly 130 includes two rollers 140 arranged side by side, which cooperate to support the roller-shaped workpiece 110. The power assembly is used to drive one of the two rollers 140 to rotate so that the roller 140 drives the roller-shaped workpiece 110 to rotate.
[0053] It is understood that in this embodiment, by using two rollers 140 to support the roller-shaped workpiece 110, the double roller 140 support structure forms a V-shaped stable support surface. Compared with single roller 140 support, it can effectively reduce the radial runout of the roller-shaped workpiece 110 during rotation, which is beneficial to improving welding accuracy. In addition, the power component drives one of the two rollers 140 to rotate, forming a drive configuration of active roller 140 and driven roller 140, which ensures transmission efficiency and reduces energy consumption.
[0054] Furthermore, the support assembly 130 also includes a first mounting bracket 150, with two rollers 140 rotatably mounted on the first mounting bracket 150. The worktable 100 includes a table body 160 and an adjusting guide rail 170 mounted on the table body 160. The length direction of the adjusting guide rail 170 is parallel to the length direction of the roller-shaped workpiece 110. The first mounting bracket 150 is mounted on the adjusting guide rail 170 and can be adjusted and fixed in position on the adjusting guide rail 170.
[0055] In this embodiment, by utilizing the position adjustment cooperation of the first mounting bracket 150 and the adjusting guide rail 170, the position of the support component 130 can be adjusted. Thus, the support position of the support component 130 on the roller workpiece 110 can be adjusted according to the length of the roller workpiece 110, thereby adapting to the welding processing of roller workpieces 110 of different sizes.
[0056] Specifically, the adjusting guide rail 170 is provided with a plurality of first mounting holes arranged along the length direction of the adjusting guide rail 170, and the first mounting bracket 150 is fixed at different positions of the adjusting guide rail 170 by bolts connecting different first mounting holes.
[0057] In some specific embodiments, in order to ensure the stability of the rotation speed of the roller 140 and the stability of the welding, the power component can be set as a motor.
[0058] In some specific embodiments, in order to make the support of the roller workpiece 110 by the drive device more stable, at least two support components 130 can be provided, so that the drive device can provide at least two support positions distributed along the axial direction of the roller workpiece 110.
[0059] Furthermore, the power assembly can drive one of the rollers 140 of one of the support components 130 to rotate, thereby reducing the number of power assemblies and helping to reduce the structural complexity of the welding equipment.
[0060] Reference Figure 2 and Figure 3 The positioning device is set on the worktable 100 and is used to abut against the free end of the assembly shaft head 120 pre-installed at the end of the roller workpiece 110 to position the assembly shaft head 120.
[0061] It is understandable that when the roller workpiece 110 rotates, it drives the assembly shaft head 120 to rotate. The positioning device abuts against the free end of the assembly shaft head 120. On the one hand, the positioning device can axially limit the assembly shaft head 120 to prevent the assembly shaft head 120 from axially shifting during rotation. On the other hand, when the assembly shaft head 120 rotates, the contact between the positioning device and the free end of the assembly shaft head 120 can generate frictional resistance. This frictional resistance of the positioning device against the assembly shaft head 120 can prevent the assembly shaft head 120 from radially wobbling during rotation, thereby improving the welding accuracy of the workpiece.
[0062] Specifically, the positioning device includes a positioning sensor 180, which is used to abut against the free end of the assembly shaft head 120 at one end of the positioning roller workpiece 110. The positioning sensor 180 can detect whether the assembly shaft head 120 is in place with the positioning sensor 180 and energize the assembly shaft head.
[0063] It is understood that in this embodiment, the positioning sensor 180 is used to position the free end of the assembly shaft head 120 at one end of the roller workpiece 110. This allows the positioning sensor 180 to detect whether the assembly shaft head 120 is in place with the positioning sensor 180 and to energize the assembly shaft head while positioning it. On the one hand, the automatic detection of the positioning sensor 180 replaces manual visual inspection, which helps to improve positioning efficiency and accuracy and reduce the welding defect rate caused by abnormal positioning of the assembly shaft head 120 by the positioning device. On the other hand, the positioning sensor 180 also has the function of current transmission. After the controller of the automatic welding machine is turned on, the current is transmitted to the workpiece through the positioning sensor 180. After the welding torch 270 senses that the workpiece is energized, the welding torch 270 automatically ignites and welds, thereby achieving the effect of automatic welding.
[0064] Furthermore, the positioning device also includes a first positioning member 190, which is movable along the axial direction of the roller workpiece 110. The first positioning member 190 is used to abut against the end of the positioning roller workpiece 110 away from the positioning sensor 180, or to abut against the free end of the assembly shaft head 120 pre-installed on the end of the roller workpiece 110 away from the positioning sensor 180, so that the first positioning member 190 and the positioning sensor 180 cooperate to form a bidirectional positioning structure, which is beneficial to improving the positioning stability of the positioning device. In addition, the first positioning member 190 is movable along the axial direction of the roller workpiece 110, so that the first positioning member 190 can press against or release the workpiece by moving, thereby facilitating the loading and unloading of the workpiece between the first positioning member 190 and the positioning sensor 180.
[0065] Furthermore, the positioning device also includes two first adjustment mechanisms 200, which are mounted on the worktable 100. The two first adjustment mechanisms 200 are used to adjust the height of the positioning sensor 180 and the first positioning element 190, respectively. The first adjustment mechanism 200 includes a second mounting bracket 210, a first lifting seat 220 that slides up and down on the second mounting bracket 210, and a first screw 230 that drives the first lifting seat 220 to rise and fall. The positioning sensor 180 or the first positioning element 190 is mounted on the first lifting seat 220.
[0066] It is understood that in this embodiment, by using two first adjustment mechanisms 200 to adjust the height of the positioning sensor 180 and the first positioning component 190 respectively, the positioning device can adapt to the welding processing requirements of roller workpieces 110 with different diameters. In addition, the first adjustment mechanism 200 uses the first screw 230 to drive the first lifting seat 220 to rise and fall, so that the adjustment process of the first adjustment mechanism 200 is smooth and without shaking. At the same time, the threaded engagement between the first screw 230 and the first lifting seat 220 or between the first screw 230 and the second mounting bracket 210 can achieve self-locking, which makes it easy to lock the height of the first lifting seat 220.
[0067] In some specific embodiments, the first positioning member 190 can be slidably connected to the first lifting seat 220. The first positioning member 190 moves along the axial direction of the roller workpiece 110 by sliding on the first lifting seat 220. The first lifting seat 220 is fixed to the side of the first positioning member 190 by bolts.
[0068] In other embodiments, the first positioning member 190 may be threadedly connected to the first lifting seat 220, and the first positioning member 190 may be rotated to move along the axial direction of the roller workpiece 110 through thread engagement with the first lifting seat 220.
[0069] In some specific embodiments, in order to enable the first positioning element 190 and the positioning sensor 180 to adapt to the welding requirements of roller workpieces 110 and assembly shaft heads 120 of different lengths, the second mounting bracket 210 can be set on the adjusting guide rail 170, thereby achieving the position adjustment effect of the second mounting bracket 210.
[0070] Reference Figure 4 The welding device is set on the worktable 100 and located on one side of the roller workpiece 110. The welding device is used to weld the connection between the roller workpiece 110 and the assembly shaft head 120.
[0071] Specifically, the welding apparatus includes a second adjusting mechanism 240, a third adjusting mechanism 250, and a welding assembly 260. The third adjusting mechanism 250 is disposed on the second adjusting mechanism 240, and the welding assembly 260 is disposed on the third adjusting mechanism 250. One of the second adjusting mechanism 240 and the third adjusting mechanism 250 is used to adjust the height of the welding assembly 260, and the other of the second adjusting mechanism 240 and the third adjusting mechanism 250 is used to adjust the horizontal position of the welding assembly 260.
[0072] It is understood that this embodiment uses the second adjustment mechanism 240 and the third adjustment mechanism 250 to adjust the height and horizontal position of the welding assembly 260, thereby achieving precise adjustment of the welding position of the welding assembly 260 to adapt to the welding requirements of roller workpieces 110 and assembly shaft heads 120 of different sizes, ensuring the consistency of workpiece processing, and realizing 360° automatic and precise welding processing of workpieces.
[0073] Specifically, one of the second adjustment mechanism 240 and the third adjustment mechanism 250 may include a third mounting frame, a second lifting seat that is slidably mounted on the third mounting frame, and a second screw that drives the second lifting seat to rise and fall; the other of the second adjustment mechanism 240 and the third adjustment mechanism 250 may include a fourth mounting frame, a first translation seat that is slidably mounted on the fourth mounting frame, and a third screw that drives the first translation seat to translate.
[0074] In some specific embodiments, the welding assembly 260 includes a welding torch 270 and a first cylinder 280. The first cylinder 280 is disposed on the third adjustment mechanism 250. The first cylinder 280 is used to drive the welding torch 270 to approach and move away from the connection between the roller workpiece 110 and the assembly shaft head 120, thereby enabling the welding torch 270 to quickly approach and move away from the welding position, ensuring that when welding is required, the welding torch 270 can quickly and smoothly contact the weld point for welding, and then quickly move away from the welding position after welding, so as to avoid the welding torch 270 obstructing the loading and unloading of the workpiece.
[0075] Furthermore, a sliding member can be slidably provided on the third adjustment mechanism 250, and the welding torch 270 can be mounted on the sliding member, thereby making the movement of the welding torch 270 driven by the first cylinder 280 more stable.
[0076] In some specific embodiments, the welding device further includes a turntable 290, a second adjustment mechanism 240 is disposed on the turntable 290, the turntable 290 is used to adjust the welding angle direction of the welding assembly 260, the turntable 290 is provided with an arc-shaped groove 300 that runs vertically through the turntable, the worktable 100 is provided with a fixing bolt, the fixing bolt passes through the arc-shaped groove 300, and the fixing bolt is used to fix the turntable 290.
[0077] It is understood that this embodiment uses the rotation of the turntable 290 to adjust the welding angle of the welding assembly 260, adapting to the welding requirements of welds in different directions, improving the flexibility of the welding angle of the welding assembly 260, and facilitating the achievement of the best welding effect through a suitable welding angle. In addition, the use of fixing bolts and arc groove 300 for limiting facilitates precise fixing of the angle position of the turntable 290.
[0078] In some specific embodiments, in order to achieve simultaneous and precise welding of both ends of the roller workpiece 110 and improve welding efficiency, two welding devices can be provided, and the two welding devices can weld both ends of the roller workpiece 110 simultaneously to achieve dual-station welding.
[0079] In some specific embodiments, the automatic welding machine also includes a waste solder collection component 310, which is disposed on the worktable 100 and located below the connection between the roller workpiece 110 and the assembly shaft head 120. The waste solder collection component 310 is used to collect waste generated during the welding process, thereby realizing the automatic guidance and discharge of waste, reducing the frequency of manual cleaning, and reducing the equipment cleaning and maintenance time.
[0080] Specifically, the welding process of a high-precision automatic welding machine based on shaft head anti-offset in this embodiment is as follows: the roller workpiece 110 with the pre-installed assembled shaft head 120 is placed on the two rollers 140 of the support assembly 130, and the controller is started to control the welding guns 270 of the welding devices at both ends to perform welding synchronously, so as to complete the welding processing of both ends of the roller workpiece 110 in one go.
