Description

Technical Field

[0001] This utility model belongs to the field of transformer riser support frame welding technology, specifically a transformer riser support frame welding workstation. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers are fundamental equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, and urban communities.

[0003] The transformer riser is a crucial component of a transformer, responsible for supporting the transformer and enhancing the insulation strength of the transformer windings. It also contributes to the overall stability of the transformer, ensuring its normal operation. A transformer riser typically consists of two parts: a support frame and insulating supports. The support frame, the main body of the riser, is generally made of metal and supports the entire transformer.

[0004] The transformer riser support frame includes a cylindrical support frame body and support frame flanges welded to both ends of the support frame body. During the welding and manufacturing of the transformer riser support frame, welding is required on both the inner and outer sides of both ends of the support frame body (where it fits against the support frame flanges). For smaller transformer riser support frames, traditional manual welding requires workers to reach into the workpiece (transformer riser support frame) to perform welding operations. The working space is small, the field of vision is not wide, which easily leads to poor welding quality. In addition, the work intensity is high, the work efficiency is low, and it is easy to cause injury to the operators, which is very dangerous. Utility Model Content

[0005] To address the problems of traditional manual welding of transformer riser support frames, which requires workers to reach inside the workpiece for welding, resulting in limited working space, poor visibility, low welding quality, high work intensity, low efficiency, and potential injury to operators, this utility model provides a transformer riser support frame welding workstation.

[0006] This utility model is achieved through the following technical solution:

[0007] A welding workstation for a transformer riser support frame includes a clamping mechanism and a welding robot mounted on one side of the clamping mechanism. The clamping mechanism includes a second base, on which a tilting drive device is mounted. The tilting end of the tilting drive device is connected to a rotary drive device via a mounting plate. The rotary drive device has a chuck mounted on its rotary end. The chuck has at least three claws arranged in a circular array to clamp the inner side of the support frame flange at one end of the transformer riser support frame. Each claw has a clamping block, and the outer clamping surface of the clamping block forms an acute angle with the claw. The rotary drive device's rotation axis is aligned with the transformer riser support frame's axis, and the tilting drive device's tilting axis is perpendicular to the transformer riser support frame's axis.

[0008] A further improvement of this utility model is that the angle between the outer clamping surface of the card block and the card claw is 75 degrees.

[0009] A further improvement of this utility model is that the outer clamping surface of the card block is covered with a rubber protective layer.

[0010] A further improvement of this utility model is that the side of the claw near the transformer riser support frame is smoothed.

[0011] A further improvement of this utility model is that the mounting plate has a rectangular plate structure, with its middle part connected and installed to the flipping end of the flipping drive device; the side of the mounting plate away from the flipping drive device has a number of mounting holes spaced apart along its length direction, which can be connected and installed to the rotary drive device.

[0012] A further improvement of this utility model is that the mounting plate has a rectangular plate structure, with its middle part connected to the flipping end of the flipping drive device; a slide rail and a rack are mounted on the mounting plate along its length direction; a slider and a drive motor that slide in cooperation with the slide rail are mounted on the side of the rotary drive device near the mounting plate; and a gear that meshes with the rack is mounted on the output end of the drive motor.

[0013] A further improvement of this utility model is that limit blocks capable of limiting the rotation drive device are installed at both ends of the mounting plate.

[0014] A further improvement of this utility model is that both the flipping drive device and the slewing drive device are rotary worktables.

[0015] A further improvement of this utility model is that there are two clamping mechanisms, and the welding robot is positioned between the two clamping mechanisms.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] Initially, the chuck is horizontal and upward-facing. The transformer riser support frame, which is being hoisted and spot-welded, is placed vertically on the chuck. The support frame's flange is secured by locking blocks on the jaws, and the inclined surfaces on the outer sides of the locking blocks ensure reliable clamping of the support frame, guaranteeing a secure clamping. A rotary drive mechanism rotates the transformer riser support frame along its axis, and a welding robot performs welding on the four inner and outer circumferential seams. A tilting drive mechanism allows for the rotation and adjustment of the rotary drive mechanism (transformer riser support frame), enabling flexible welding operations and improved adaptability for the welding robot. The overall structure is simple, easy to operate, highly efficient in welding, produces high-quality welds, and ensures good safety. Attached Figure Description

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figure 1-4 As shown, an optional embodiment of this utility model discloses a welding workstation for a transformer riser support frame, including a clamping mechanism and a welding robot 3 installed on one side of the clamping mechanism; the clamping mechanism includes a second base 4, on which a flipping drive device 41 is installed, and a rotary drive device 43 is connected to the flipping end of the flipping drive device 41 via a mounting plate 42; a chuck 5 is installed on the rotary end of the rotary drive device 43, and at least three claws 51 are arranged in a circular array on the chuck 5, which can clamp the inner side of the support frame flange 11 at one end of the transformer riser support frame; a clamping block 52 is provided on the claw 51, and the outer clamping surface of the clamping block 52 forms an acute angle with the claw 51; the rotation axis of the rotary drive device 43 is consistent with the axis of the transformer riser support frame, and the flipping axis of the flipping drive device 41 is perpendicular to the axis of the transformer riser support frame.

[0026] Initially, chuck 5 is horizontal and upward, with the transformer riser support frame, which is being hoisted and spot-welded, placed vertically on chuck 5. The support frame flange 11 is secured to the inside by the locking blocks 52 on the jaws 51, and the inclined surface on the outer side of the locking blocks 52 ensures reliable clamping of the transformer riser support frame, guaranteeing a secure clamping. The transformer riser support frame rotates along its axis via a rotary drive device 43, and the welding robot 3 welds the four inner and outer circumferential seams of the support frame. Furthermore, the rotary drive device 43 (transformer riser support frame) is rotated and adjusted via a tilting drive device 41, enabling the welding robot 3 to perform flexible welding operations with better adaptability. The overall structure is simple, easy to operate, highly efficient in welding, produces high-quality welds, and is safe.

[0027] This welding workstation is suitable for welding operations on transformer riser support frames of smaller dimensions.

[0028] The angle between the outer clamping surface of the clamping block 52 and the clamping claw 51 is 75 degrees. This ensures reliable clamping of the inner side of the support flange 11 of the transformer riser support frame.

[0029] The outer clamping surface of the clamping block 52 is covered with a rubber protective layer. This increases the clamping friction between the clamping block 52 and the inner side of the support frame flange 11, thus ensuring reliable clamping.

[0030] The side of the claw 51 closest to the transformer riser support frame is smoothed. After the support frame flange 11 of the transformer riser support frame is placed on the claw 51, the smooth surface of the claw 51 (reducing relative static friction) can effectively enable the convenient movement and clamping of the clamping block 52 on the support frame flange 11.

[0031] Among them, the flipping drive device 41 and the rotary drive device 43 are both rotary worktables, which are provided with rotational power by servo motors to achieve precise adjustment of the rotation angle and ensure the reliability of welding operations.

[0032] In one embodiment, such as Figure 2-3 As shown, the mounting plate 42 has a rectangular plate structure, with its middle section connected to the flipping end of the flipping drive device 41. Along its length, the side of the mounting plate 42 away from the flipping drive device 41 has several mounting holes that can be connected to the rotary drive device 43. This ensures reliable installation of the rotary drive device 43 and the mounting plate 42. Furthermore, when welding different transformer riser support frames, bolts can be selectively passed through the mounting holes at different positions, achieving operational flexibility.

[0033] In another embodiment, the mounting plate 42 has a rectangular plate structure, with its middle part connected to the flipping end of the flipping drive device 41. A slide rail and a rack are mounted on the mounting plate 42 along its length. A slider that slides along the slide rail and a drive motor are mounted on the side of the rotary drive device 43 near the mounting plate 42. A gear that meshes with the rack is mounted on the output end of the drive motor. By driving the gear to rotate through the drive motor, the rotary drive device 43 (transformer riser support frame) can be flexibly and conveniently adjusted on the mounting plate 42, exhibiting strong adaptability.

[0034] Furthermore, limit blocks are installed at both ends of the mounting plate 42 to limit the rotation drive device 43. This enables hard limiting of the rotation drive device 43 and prevents derailment.

[0035] like Figure 1 As shown, there are two clamping mechanisms, and the welding robot 3 is positioned between the two clamping mechanisms. Each welding robot 3 is equipped with two clamping mechanisms; one clamping mechanism performs the welding operation, while the other clamping mechanism handles loading and unloading, achieving high-efficiency welding operations.

[0036] In the initial state, the chuck 5 of this transformer riser support frame welding workstation is horizontal and upward. The transformer riser support frame to be hoisted and spot-welded is placed vertically on the chuck 5, and is clamped to the inner side of the support frame flange 11 by the clamping blocks 52 on the jaws 51. The inclined surface on the outer side of the clamping blocks 52 ensures reliable clamping of the transformer riser support frame, guaranteeing the secure clamping of the transformer riser support frame. The transformer riser support frame is rotated along its axis by the rotary drive device 43, and the welding robot 3 performs welding on the four inner and outer circumferential seams of the transformer riser support frame. The rotary drive device 43 (transformer riser support frame) is rotated and adjusted by the flip drive device 41, thereby enabling the welding robot 3 to perform flexible welding operations and improve adaptability. The overall structure is simple, easy to operate, efficient in welding, produces good welding quality, and is safe.
