Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a rotary workpiece welding auxiliary tooling. Background Technique

[0002] As an important metal connection means, welding technology occupies a crucial position in the manufacturing industry. Whether it is aerospace, automotive manufacturing or building steel structures, welding is an indispensable key process. With the continuous improvement of industrial automation level, welding technology is also constantly innovating and developing to meet the production requirements of higher precision and higher efficiency.

[0003] In modern welding workshops, special welding toolings are usually equipped. The function of these toolings is to conveniently adjust the position of workpieces to meet different welding requirements, and turntable-type toolings are particularly common. For example, a welding tooling turntable (publication number: CN211361183U) disclosed in the prior art enables the welding table to have an automatic rotation function by using a driving motor and a transmission component, which is beneficial to the continuity and accuracy of welding operations. Such toolings can adjust the position of workpieces automatically or manually, making the weld seam easier to approach the welding tool, thereby improving the welding quality and efficiency. In this way, operators can focus more on the welding itself without worrying about the adjustment of the workpiece position.

[0004] However, the problem existing in the prior art is that the rotation speed and tilt angle of the welding table are also key factors affecting the welding quality. When welding some workpieces with complex structures, operators need to adjust the rotation speed and tilt angle of the welding table according to different welding parts. However, the existing welding tables often require operators to put down the welding torch and mask in their hands and then adjust them, which results in the inability to guarantee the continuity of the welding process. Frequent pauses not only reduce work efficiency but also may affect the welding quality. Especially in the case of multi-angle and multi-position welding, this way of frequently adjusting the workpiece position is particularly inconvenient, increasing the complexity and time cost of operation and having an adverse impact on work efficiency. Content of the Utility Model

[0005] The utility model provides a rotary workpiece welding auxiliary tooling, which can solve the technical problem that the existing welding tooling cannot guarantee the continuity of the welding process during use.

[0006] The present application provides the following technical solutions:

[0007] A rotary workpiece welding auxiliary tooling comprises a base, a swivel assembly rotatably connected to the base, a welding table detachably fixedly connected to the swivel assembly, and a deflection motor fixedly mounted on the base for driving the swivel assembly to rotate, wherein the swivel assembly comprises a swivel motor for driving the welding table to rotate; and further comprises a first foot switch electrically connected to the swivel motor and a second foot switch electrically connected to the deflection motor, wherein the first foot switch comprises a base, a pedal rotatably connected to the base, a pressure sensor and a controller fixedly mounted in the base, a pressure block for touching the sensing end of the pressure sensor is fixedly arranged at the bottom of the pedal, and the second foot switch has the same structure as the first foot switch.

[0008] Beneficial effects:

[0009] 1. Improve welding quality: The rotation speed and tilt angle of the welding table are adjustable. This design is conducive to meeting the various situations where multi-angle and multi-position welding is required when welding complex workpieces. Through the independent control of the rotary motor and the deflection motor, the operator can flexibly adjust the position and speed of the welding table according to the actual welding needs, and cooperate with the operator's hand welding movements to ensure that each welding part can be optimally processed, thereby improving welding quality and efficiency.

[0010] 2. Ensure the continuity of the welding process: The setting of the foot switch allows the operator to control the rotation and tilt of the welding table by stepping on it without putting down the welding gun and mask. This design is conducive to ensuring the continuity of the welding process, reducing the interruption of welding due to frequent adjustment of the rotation speed and tilt angle of the welding table, and improving work efficiency. At the same time, the use of the foot switch also makes the operation more convenient, reduces the burden of hand operation, and improves the operating experience.

[0011] 3. The adjustment process is more accurate: The pressure sensor is used as the sensing element, making the adjustment process linear and more accurate. Thanks to the pressure sensor's ability to sensitively detect the pressure changes applied by the operator and convert these changes into motor control signals through the controller, the speed and tilt angle of the welding table can be accurately controlled. This linear control method not only improves the accuracy of the operation, but also makes the entire welding process more stable and reliable, further improving the welding quality.

[0012] Furthermore, as an improvement, a stopper is fixedly arranged on the base, and a seesaw is rotatably arranged on the pedal, and the seesaw contacts the stopper when no external force is applied.

[0013] Beneficial effects: By setting up the combination of the stop block and the seesaw, an insurance mechanism is provided for the use of the pedal. Specifically, if an operator wants to step on the pedal, they must first step on the seesaw to make it rotate and get out of the restriction of the stop block. This design ensures that the pedal will not be accidentally triggered, thus avoiding potential safety hazards caused by misoperation. It not only improves the safety of operation but also makes the control of the entire system more reliable and precise.

[0014] Further, as an improvement, a protective cover covering the pedal is fixedly arranged on the base.

[0015] Beneficial effects: By fixedly arranging a protective cover on the base to cover the pedal, it can be ensured that the pedal will not be accidentally stepped on in the non-operating state, thus avoiding equipment mis-start or misoperation caused by accidental touch. This design not only improves the safety of operation but also reduces the potential risks caused by accidental touch, making the equipment more reliable and stable during use.

[0016] Further, as an improvement, the welding table is selected as a four-jaw centering chuck.

[0017] Beneficial effects: The four-jaw centering chuck can provide accurate and firm clamping force, ensuring that the workpiece remains stable and immobile during the welding process, thus significantly improving the welding quality and precision. Through the coordinated action of the four jaws, the chuck can adapt to workpieces of different shapes and sizes, ensuring that each contact point can be evenly stressed and avoiding problems such as workpiece deformation or displacement caused by improper clamping. This reliable fixing method not only improves the welding efficiency but also reduces welding defects caused by workpiece movement, making the entire welding process smoother and more efficient.

[0018] Further, as an improvement, the first foot switch and the rotary motor, as well as the second foot switch and the deflection motor, are electrically connected through wires.

[0019] Beneficial effects: By realizing electrical connection through wires, this design not only ensures the stability and reliability of signal transmission but also gives the operator greater flexibility. By dragging the wires to adjust the placement position of the foot switch, it can meet the habitual requirements of different operators, enabling each user to find the most suitable way of operation for themselves. This flexible layout not only improves the convenience and comfort of operation but also reduces the inconvenience caused by fixed positions, thus improving the overall work efficiency and operation experience.

[0025] The following is a further detailed description through specific embodiments:

[0026] The markings in the attached drawings of the specification include: base 1, rotary assembly 2, housing 21, four-jaw centering chuck 3, deflection motor 4, first foot switch 5, base 51, protective cover 52, pedal 53, pressure sensor 54, pressing block 55, stop block 56, seesaw 57, second foot switch 6, and electric wire 7.

[0027] Embodiment 1

[0028] As Figures 1 - 5 shown, the rotary workpiece welding auxiliary tooling includes a base 1, a rotary assembly 2 rotatably connected to the side plates on both sides of the base 1, a four-jaw centering chuck 3 detachably and fixedly connected to the rotary assembly 2, and a deflection motor 4 fixedly installed on the side of the base 1 for driving the rotary assembly 2 to rotate. The deflection motor 4 is a reduction motor. The rotary assembly 2 includes a housing 21 rotatably connected to the base 1, a rotary motor and a reducer fixedly installed in the housing 21 for driving the four-jaw centering chuck 3 to rotate.

[0029] In this embodiment, the rotary workpiece welding auxiliary tooling further includes a first foot switch 5 electrically connected to the rotary motor and a second foot switch 6 electrically connected to the deflection motor 4. In this embodiment, all electrical connections are realized by connecting electric wires 7. The electric wires 7 have a surplus to facilitate the user to move the position according to needs. As Figure 3 、 Figure 4As shown in the figure, the first foot switch 5 includes a base 51, a protective cover 52 fixedly arranged on the base 51 and completely covering the pedal 53, a pedal 53 rotatably connected to the base 51, a pressure sensor 54 fixedly installed in the base 51, and a controller. The pressure sensor, the controller, and the rotary motor are electrically connected in sequence. A pressing block 55 for pressing the sensing end of the pressure sensor 54 is fixedly arranged at the bottom of the pedal 53. When the operator steps on the foot pedal with the foot, the foot pedal starts to rotate until the pressing block 55 touches the sensing end of the pressure sensor 54. On this basis, the operator continues to exert force so that the sensing end of the pressure sensor 54 bears a greater pressure, and transmits the sensed pressure data to the controller. The controller controls the rotary motor to drive the four-jaw centering chuck to rotate, and the rotation speed of the four-jaw centering chuck gradually increases as the pressure data increases. The second foot switch 6 has the same structure as the first foot switch 5. When the operator steps on the second foot switch 6, the inclination angle of the whole rotary assembly 2 changes.

[0030] It is worth mentioning that, as shown in combination with Figure 4 and Figure 5 a stop block 56 is welded and fixed on the base 51, a rocker 57 is rotatably arranged on the pedal 53. Both ends of the rocker 57 extend out of the top and bottom of the pedal 53. A torsion spring is installed at the rotational connection between the rocker 57 and the pedal 53. When there is no external force, the end of the rocker 57 extending out of the bottom of the pedal 53 abuts against the stop block 56. If the operator wants to step on the pedal 53, they need to step on the rocker 57 first to make the rocker 57 rotate clockwise as Figure 4 shown to leave the stop block 56.

[0031] The specific application process is as follows:

[0032] I. Preparation process: First, power on the rotary motor, the deflection motor 4, the first foot switch 5, and the second foot switch 6. At this time, both the rotary motor and the deflection motor 4 are in a stationary state. Then, use the four-jaw centering chuck 3 to clamp and fix the workpiece to be welded at the central position of the four-jaw centering chuck 3. Then, drag the first foot switch 5 and the second foot switch 6 to the positions where the operator is used to stepping on with the foot. The operator then picks up the welding tools (welding torch and mask) and prepares for the welding operation.

[0033] II. Welding process: During the process of the operator using the welding tools to weld the workpiece, they can step on the first foot switch 5 and the second foot switch 6 at any time to adjust the rotation speed and inclination angle of the workpiece, so as to meet the continuously changing position requirements when welding workpieces with complex structures, without having to frequently pause the welding action in hand, which is beneficial to ensuring the continuity of the welding process and improving the working efficiency and quality of the welded workpiece.
