When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This invention relates to a silicon steel strengthening welding device. For example, the silicon steel strengthening welding device includes a positioning assembly and a welding assembly. The positioning assembly includes a positioning plate and two clamping members. The positioning plate has a weld groove. For example, the two clamping members are respectively disposed on opposite sides of the weld groove to clamp the thin-walled silicon steel pipe and align the weld of the thin-walled silicon steel pipe with the weld groove. For example, the welding assembly is disposed at the bottom of the positioning plate and aligned with the weld groove to weld the thin-walled silicon steel pipe.

[0023] Please see Figure 1 and Figure 2 This invention relates to a silicon steel strengthening welding device 100, comprising a positioning component 10 and a welding component 20. The positioning component includes a positioning plate 11 and two clamping members 12. The positioning plate has a weld groove 115. The two clamping members are respectively disposed on opposite sides of the weld groove to clamp the thin-walled silicon steel pipe and align the weld of the thin-walled silicon steel pipe with the weld groove. The welding component is disposed at the bottom of the positioning plate and aligned with the weld groove to weld the thin-walled silicon steel pipe.

[0024] When the silicon steel strengthening welding equipment welds and forms a thin-walled silicon steel tube, the thin-walled silicon steel tube is placed on the positioning plate and clamped on opposite sides by the two clamping members to position the tube. Then, the weld seam of the thin-walled silicon steel tube is aligned with the weld groove, and the welding assembly is aligned with the weld groove to weld the tube. Because the positioning plate in the silicon steel strengthening welding equipment has two clamping members, the two clamping members can respectively clamp opposite sides of the thin-walled silicon steel tube, thereby stably positioning the tube and preventing bending deformation, improving welding quality and facilitating the forming of the thin-walled silicon steel tube.

[0025] For example, in order to facilitate welding the thin-walled silicon steel pipe, the positioning plate is rectangular plate, the thickness of the positioning plate is 3-5mm. The four corners of the positioning plate are provided with rounded corners. The welding assembly includes a welding drive 21 and a welding piece (not shown), the welding drive is provided on the positioning plate. The welding piece is connected to the welding drive, and the welding piece is aligned with the weld groove. The thin-walled silicon steel pipe is formed with a weld, which extends along the length direction of the thin-walled silicon steel pipe and is aligned with the weld groove to be welded. The weld groove extends along the length direction of the positioning plate, and one end of the weld groove penetrates the end of the positioning plate. The width of the weld groove is greater than the width of the weld, and the length of the weld groove is greater than the length of the weld. The welding assembly further includes two mounting blocks 22, a lead screw 23 and a stepper motor 24, the two mounting blocks are mounted on the positioning plate and are respectively located at opposite ends of the weld groove, the opposite ends of the lead screw are respectively mounted on the two mounting blocks, and the stepper motor is mounted on the end of the lead screw. The welding assembly further includes a sliding frame 25, one end of the sliding frame is screwed on the lead screw, and the welding drive is mounted on the sliding frame. By providing the sliding frame, the lead screw and the stepper motor can be used to drive the sliding frame to move along the positioning plate, and finally drive the welding drive to drive the welding piece to move along the weld groove.

[0026] For example, it is particularly important to facilitate guiding the welding piece, the opposite sides of the weld groove are respectively formed with guiding surfaces, the two guiding surfaces are planes, the top of the sliding frame is provided with a rectangular guide block 255, the rectangular guide block is slidingly arranged in the weld groove, and the opposite side surfaces of the rectangular guide block are respectively slidingly abutted on the two guiding surfaces. Further, for example, the opposite sides of the rectangular guide block are respectively provided with clamping strips (not shown), the two guiding surfaces are respectively provided with guide grooves, the two clamping strips are respectively slidingly clamped in the two guide grooves, and the top surface of the rectangular guide block is lower than the top surface of the positioning plate. By providing the two clamping strips, on the one hand, the sliding frame and the welding drive are supported, and on the other hand, the welding drive is guided to move in alignment with the weld, thereby improving the welding precision.

[0027] For example, in order to facilitate positioning of the thin-walled silicon steel tube, the positioning assembly comprises the two clamping members, two positioning blocks 13 and two elastic pushers 14. Two strip-shaped positioning grooves are further recessed on the positioning plate, and are respectively located on opposite sides of the weld groove. The cross section of the strip-shaped positioning groove is semicircular. The two clamping members are cylindrical clamping members, and are respectively rollingly arranged in the two strip-shaped positioning grooves. For example, the depth of the strip-shaped positioning groove is shallow, and in the case of positioning the cylindrical clamping members, the cylindrical clamping members can roll out of the strip-shaped positioning groove after being slightly stressed. The two positioning blocks are respectively fixed on opposite sides of the positioning plate, and the two elastic pushers are respectively connected to the two positioning blocks. The two elastic pushers are respectively elastically abutted on the two cylindrical clamping members, and the two cylindrical clamping members are used for clamping the thin-walled silicon steel tube. The two elastic pushers are used for pushing the two cylindrical clamping members to move towards each other, so as to clamp the thin-walled silicon steel tube. The surface of the elastic pusher is a concave arc surface, so as to be matched with the surface of the cylindrical clamping member. The elastic pusher is connected to the positioning block through a compression spring.

[0028] For example, in order to change the distance between the two cylinder holders and to hold the thin-walled silicon steel tube more tightly on the positioning plate, the silicon steel reinforcing welding device further comprises a holding assembly 40, which comprises a mounting frame 41, a holding cylinder 42, a connecting rod 43, a connecting rod 44 and a holding cylinder 45. The mounting frame comprises a horizontal plate 411 and a vertical plate 415. One end of the horizontal plate is connected to the end of the positioning plate, and the vertical plate is vertically arranged at the end of the horizontal plate and spaced from the positioning plate. Two extension rods 418 are protruded on the vertical plate, and a guide groove 4158 is recessed on the vertical plate. The guide groove extends in the vertical direction and is located between the two extension rods. The bottom end of the guide groove extends to the horizontal plate. The holding cylinder is mounted on the two extension rods. The connecting rod is slidingly arranged in the guide groove. The upper end of the connecting rod is connected to the output shaft of the holding cylinder. One end of the connecting rod is vertically connected to the lower end of the connecting rod, and the other end is rotatably connected to the end of the holding cylinder. The holding cylinder is held between the two cylinder holders. The opposite sides of the bottom of the holding cylinder are held on the two cylinder holders, and the center of the bottom of the holding cylinder is pressed on the thin-walled silicon steel tube to position the thin-walled silicon steel tube on the weld groove. The length of the holding cylinder is less than the length of the cylinder holder, so that a guide notch 458 is formed at one end of the holding cylinder to facilitate the thin-walled silicon steel tube to enter between the two cylinder holders. The outer diameter of the holding cylinder is smaller than the outer diameter of the cylinder holder. Therefore, it is convenient for the holding cylinder to enter between the two cylinder holders or even the lower part of the two cylinder holders to position the thin-walled silicon steel tube and improve the positioning accuracy. For example, the connecting rod and the holding cylinder are coaxially arranged. Through the rotation of the connecting rod and the holding cylinder, it is convenient for the holding cylinder to rotate along its central axis, and the adaptability of the holding cylinder is improved. For example, the holding cylinder is used to drive the holding cylinder up and down through the connecting rod, thereby adjusting the distance between the two cylinder holders, adjusting the clamping and positioning force of the two cylinder holders on the thin-walled silicon steel tube, and improving the positioning stability. For example, in order to facilitate the increase of the clamping force of the two cylinder holders, one end of each cylinder holder is coaxially provided with a pivot 128. The end of the pivot is rotatably sleeved with a bearing, and the two bearings are arranged adjacent to the mounting frame. A ring-shaped tension belt 125 is sleeved on the two bearings. The one end of the two cylinder holders can be tightened by the ring-shaped tension belt. The elastic push pieces are arranged adjacent to the opposite ends of the cylinder holder, respectively. The opposite ends of the cylinder holder can be tightened by the ring-shaped tension belt and the elastic push piece, respectively. For example, the ring-shaped tension belt is located below the connecting rod and is also used to limit the downward position of the connecting rod. When the connecting rod moves downward to the ring-shaped tension belt, the continuous downward movement of the holding cylinder is limited to avoid crushing the thin-walled silicon steel tube.

[0029] Through the arrangement of the positioning assembly, the thin-wall silicon steel pipe can be positioned left and right conveniently, and through the arrangement of the abutting assembly, the thin-wall silicon steel pipe can be conveniently abutted on the positioning plate, and the left and right clamping force of the two cylindrical clamping pieces on the thin-wall silicon steel pipe can be adjusted. The tensioning force of the two elastic push-holding pieces and the loop-shaped tensioning belt can be adjusted and set in advance to stably position the silicon steel thin-wall welded pipe, the strip-shaped positioning groove can preliminarily position the cylindrical clamping piece, and the elastic push-holding piece can easily push the cylindrical clamping piece out of the strip-shaped positioning groove to adjust the abutting force, improve the positioning effect, and prevent the thin-wall silicon steel pipe from being bent.

[0030] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application.

[0031] The above-described embodiments only express several embodiments of the present application, the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
