Description

Technical Field

[0001] This invention relates to the field of frame stranding machine processing technology, and specifically to a welding and positioning process for frame stranding machines. Background Technology

[0002] A frame stranding machine is a device used for stranding long, large-section aluminum / aluminum alloy wires, bare copper wires, steel-cored aluminum stranded wires, sector conductors, and cross-linked compacted cable cores. The frame of the frame stranding machine is the main body of the machine and is used for stranding cables.

[0003] During the production process of the frame stranding machine, many parts are fixedly connected by welding. Among them, the Y-shaped parts welded to the frame body are an important part of the main body. The existing Y-shaped parts are welded and positioned manually by workers, which leads to welding errors in the Y-shaped parts themselves and positional deviations when welding the Y-shaped parts to the frame body. Once a deviation occurs, it is often necessary to cut and re-weld the welded parts, which seriously affects the processing efficiency of the frame. Summary of the Invention

[0004] The purpose of this invention is to provide a welding positioning process for frame stranding machines, which solves the technical problem of deviations in the welding of existing frames.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0007] Step 1: Position the Y-shaped part using the Y-shaped part positioning welding component, and fix the straight plate and the bent part by spot welding to obtain the semi-finished Y-shaped part;

[0008] Step 2: The straight plate and the bent part, which have been spot-welded together, are fully welded and fixed by a welding robot to obtain the finished Y-shaped part;

[0009] Step 3: Position the finished Y-shaped part from Step 2 to the semi-finished frame by positioning the welding components in the frame, and then fix the finished Y-shaped part to the semi-finished frame by spot welding.

[0010] Step 4: The Y-shaped component from Step 3 is fully welded to the semi-finished frame using a welding robot to obtain the finished frame.

[0011] As a further aspect of the present invention: the Y-shaped part positioning and welding component includes a first base, on which two sets of positioning templates are fixedly arranged side by side. The positioning templates are provided with bending part grooves that cooperate with the bending part, and the bottom of the bending part grooves is provided with straight plate grooves that cooperate with the straight plate.

[0012] As a further aspect of the present invention: a flipping frame is rotatably connected to the positioning template, and a pressure plate cylinder for pressing the bent part is installed at the lower end of the flipping frame.

[0013] As a further aspect of the present invention: a plurality of lifting cylinders are installed on the upper end of the first base, and the output end of the lifting cylinders is fixedly connected to a lifting plate for lifting the straight plate.

[0014] As a further embodiment of the present invention: the frame positioning and welding component includes a second base, on which a feeding guide rail and a transverse guide rail are fixedly mounted; a positioning and welding mechanism is slidably mounted on the feeding guide rail; and a frame support mechanism is slidably mounted on the transverse guide rail.

[0015] The frame support mechanism is used to provide rotational support for the semi-finished frame, and the positioning and welding mechanism is used to weld and position the Y-shaped part to the semi-finished frame.

A lower support plate is fixedly disposed on the lower support seat, and a vertically downward clamping cylinder is fixedly installed on the clamping support.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 and Figure 3 As shown, the present invention is a welding positioning process for a frame stranding machine, comprising the following steps:

[0032] Step 1: Position the Y-shaped part 20 using the Y-shaped part positioning welding component, and fix the straight plate 21 and the bent part 22 by spot welding to obtain the semi-finished Y-shaped part 20;

[0033] Step 2: The straight plate 21 and the bent part 22, which are connected by spot welding, are fully welded and fixed by a welding robot to obtain the finished Y-shaped part 20;

[0034] Step 3: Position the finished Y-shaped part 20 from Step 2 to the semi-finished frame by positioning the welding components in the frame, and then fix the finished Y-shaped part 20 to the semi-finished frame by spot welding.

[0035] Step 4: The Y-shaped part 20 from Step 3 is fully welded to the semi-finished frame using a welding robot to obtain the finished frame.

[0036] Please see Figure 1 and Figure 2 As shown, the Y-shaped part positioning and welding component includes a first base 11, on which two sets of positioning templates 12 are fixedly arranged side by side. The positioning templates 12 are provided with bending part grooves 14 that cooperate with the bending part 22, and the bottom of the bending part grooves 14 is provided with straight plate grooves 13 that cooperate with the straight plate 21.

[0037] A flipping frame 15 is rotatably connected to the positioning template 12. A pressure plate cylinder 17 for pressing the bending part 22 is installed at the lower end of the flipping frame 15. A flipping cylinder 16 is rotatably arranged on the first base 11. The output end of the flipping cylinder 16 is rotatably connected to the flipping frame 15.

[0038] Multiple lifting cylinders 18 are installed on the upper end of the first base 11, and the output end of the lifting cylinder 18 is fixedly connected to a lifting plate 19 for lifting the straight plate 21.

[0039] When the Y-shaped part 20 needs to be welded and positioned, the straight plate 21 is placed in the straight plate groove 13, and then the bent part 22 is placed in the bent part groove 14. The flipping cylinder 16 drives the flipping frame 15 to rotate, so that the flipping frame 15 presses against the upper end of the positioning template 12. Then, the pressure plate cylinder 17 presses the bent part 22 into the bent part groove 14, so that the bent part 22 and the groove wall of the bent part groove 14 are tightly fitted, effectively preventing the bent part 22 from deforming during the welding process and affecting the finished structure of the Y-shaped part 20. The lifting cylinder 18 drives the lifting plate 19 and the straight plate 21 to move upward, so that the upper end of the straight plate 21 presses against the bottom of the bent part 22. Then, the bent part 22 and the straight plate 21 are fixedly welded by the electric welding machine, realizing the welding positioning of the bent part 22 and the straight plate 21, ensuring that there will be no displacement during the subsequent full welding process.

[0040] The Y-shaped part positioning welding component can effectively correct the deformation of the bent part 22 and the straight plate 21, thereby making the template of the Y-shaped part 20 uniform, making the dimensions of the riveted Y-shaped part 20 stable and reliable, and reducing the workload of manual workpiece correction.

[0041] Please see Figures 3-5 As shown, the frame positioning and welding component includes a second base 30, on which a feeding guide rail 31 and a transverse guide rail 32 are fixedly mounted. A positioning and welding mechanism 39 is slidably mounted on the feeding guide rail 31, and a frame support mechanism is slidably mounted on the transverse guide rail 32. The frame support mechanism is used to provide rotational support for the semi-finished frame, and the positioning and welding mechanism 39 is used to weld and position the Y-shaped part 20 to the semi-finished frame.

[0042] After the Y-shaped part 20 is welded, it needs to be welded to the semi-finished frame. At this time, it is necessary to ensure that the Y-shaped part 20 is accurately positioned on the semi-finished frame. The Y-shaped part 20 and the semi-finished frame are welded and positioned by setting frame positioning welding components, thereby ensuring the overall welding quality of the finished frame.

[0043] The frame support mechanism includes a support base 33 slidably disposed on a transverse guide rail 32, a rotary drive 36 for driving the semi-finished frame to rotate on the support base 33, and a conveying drive component 34 for driving the support base 33 to move fixedly installed on the support base 33.

[0044] The conveying drive component 34 adopts a gear and rack drive mechanism, a belt drive mechanism, a pulley drive mechanism, or other linear drive mechanisms. These drive mechanisms are conventional linear drive mechanisms and are all existing and well-known drive mechanisms. The selection is based on the actual production situation and will not be elaborated on here.

[0045] The semi-finished frame includes a frame spindle 35, which is mounted on a rotary drive 36. Two sets of winches 37 are fixedly installed on the frame spindle 35, and a winch frame 38 is fixedly installed between the two sets of winches 37. Multiple positioning holes 381 are provided on the winch frame 38 to position the Y-shaped component 20 during installation, ensuring the stability of the Y-shaped component 20 during installation.

[0046] The positioning and welding mechanism 39 includes a main frame 391 that is slidably mounted on the feeding guide rail 31. A frame drive component 392 is fixedly mounted on the main frame 391 for driving it to slide along the feeding guide rail 31. The structure of the frame drive component 392 is the same as that of the conveying drive component 34, and it is mainly used to drive the main frame 391 to move.

[0047] A support guide rail 394 is fixedly installed on the main frame 391, and a feeding bracket 395 is slidably installed on the support guide rail 394. A feeding cylinder 393 is also installed on the main frame 391. The feeding cylinder 393 is used to drive the main frame 391 to slide along the support guide rail 394, thereby sending the Y-shaped part 20 into the winch frame 38 for welding and positioning.

[0048] A lifting guide rail 396 is fixedly installed on the feeding bracket 395, and a clamping frame 397 is slidably installed on the lifting guide rail 396. The clamping frame 397 is provided with a clamping mechanism for clamping the Y-shaped part 20.

[0049] The clamping mechanism includes a lower support 398 fixedly disposed at the lower part of the clamping frame 397 and a clamping support 399 fixedly disposed at the upper part of the clamping frame 397. A lower support plate 3981 is fixedly disposed on the lower support 398, and a vertically downward clamping cylinder 3991 is fixedly installed on the clamping support 399. An upper clamping plate 3993 is fixedly connected to the output end of the clamping cylinder 3991.

[0050] A positioning pin 3992 is fixedly installed on the clamping cylinder 3991, and a positioning hole 381 that cooperates with the positioning pin 3992 is provided on the semi-finished product frame.

[0051] The specific working method of the frame positioning welding component is as follows: The semi-finished frame is installed on the frame support mechanism, and the welded Y-shaped part 20 is hoisted onto the lower support plate 3981. The clamping cylinder 3991 drives the upper clamping plate 3993 to fix the Y-shaped part 20 onto the lower support plate 3981. Then, the frame drive component 392 drives the main frame 391 to move towards the semi-finished frame, and the rotary drive 36 drives the semi-finished frame to rotate, so that the installation position is close to the Y-shaped part 20. The Y-shaped part 20 is positioned by the cooperation of the positioning pin 3992 and the positioning hole 381. Then, the Y-shaped part 20 is welded and fixed to the semi-finished frame to achieve the welding positioning of the Y-shaped part 20. After the welding is completed, the upper clamping plate 3993 releases the clamp on the Y-shaped part 20, and the main frame 391 retracts and resets, waiting for the subsequent positioning and installation of the Y-shaped part 20.

[0052] The support base 33 and winch frame 38 of the frame positioning welding component can be moved and adjusted according to the Y-shaped parts 20 of different lengths, which facilitates the installation of Y-shaped parts 20 at different positions on the winch frame 38. The rotation of the frame main shaft 35 and the movement of each conveyor frame are electrically controlled, making operation easy. The welding positioning of Y-shaped parts 20 and semi-finished frame is mechanically positioned by positioning holes 381 and positioning pins 3992, and the welding positioning dimensions of Y-shaped parts 20 are accurate and reliable.

[0053] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
