Description

Technical Field

[0001] This application relates to the field of welding, and more specifically, to a multi-station automatic welding device. Background Technology

[0002] Welding is the process of joining metal parts using various fusible alloys (solder). Solder has a lower melting point than the materials being welded, allowing the parts to bond through intermolecular connections on their surfaces without melting. During welding, molten solder flows between the two metal parts, and under favorable conditions, a strong, tight, corrosion-resistant, and electrically and thermally conductive connection is formed between the solder and the metal.

[0003] To improve welding quality and shorten welding time, more and more companies are using welding machines and increasing the number of welding stations to improve welding efficiency. However, with the increase in welding stations, each welding operation requires manual placement of the workpiece on the work platform and manual positioning. This simultaneous placement and positioning increases the number of steps for workers. Since positioning affects welding accuracy, careless operation by workers can lead to reduced welding precision. Therefore, it is necessary to design a multi-station automatic welding equipment with automatic positioning capabilities. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a multi-station automatic welding equipment with a frame.

[0006] The welding machine body is located on the side of the frame;

[0007] Several welding tables are evenly distributed on the frame along the length of the frame, and the welding tables form the first station and the second station on both sides along the width of the frame.

[0008] The welded component consists of a rectangular base plate and steel strips set on both sides of the length of the base plate surface;

[0010] Both sets of positioning components are set on the welding table and distributed in the first and second workstations;

[0011] Among them, a positioning line is formed on the surface of the welding table along the length of the welding table and at a position that bisects both sides of the length of the welding table.

[0012] The positioning assembly consists of two clamping blocks that abut against the side wall of the base plate and a limiting block that abuts against the side wall of the steel strip; the two clamping blocks move synchronously relative to each other along the length of the welding table frame and simultaneously abut against the base plate so that the center line of the base plate along the length direction coincides with the first positioning line; the limiting block moves along the length direction of the base plate on the upper end surface of the clamping block so that the surface of the limiting block that abuts against the steel strip forms a reference surface for positioning the steel strip;

[0013] Furthermore, the surface of the welding station is recessed to form a moving groove for the two clamping blocks to move;

[0014] The movable groove extends a portion along the length of the frame; and a limiting groove is formed on the inner wall along the length of the movable groove, the limiting groove being consistent with the extension direction of the movable groove.

[0015] Two clamping blocks are inserted into the two ends of the moving groove, and the sidewalls of the clamping blocks protrude and insert into the limiting groove, so that the clamping blocks...

[0016] The block is limited in the height direction of the frame, so the clamping block can only slide along the extension direction of the moving groove;

[0017] The movable slot is equipped with a mechanism for driving the two clamping blocks to move relative to each other.

[0018] Furthermore, a drive rod is rotatably mounted at the inner end of the movable groove, and two threaded grooves are formed on the surface of the drive rod;

[0019] The two threaded grooves are located at both ends of the drive rod and extend the same distance toward the center of the drive rod in the axial direction; the two threaded grooves have opposite helical directions;

[0020] The drive rod is fitted with a nut seat that is threaded to two threaded grooves;

[0021] The clamping block is mounted on the nut seat and can move up and down.

[0022] Furthermore, the upper end face of the nut seat is recessed to form a guide hole; a guide rod for insertion into the guide hole is formed at the bottom of the clamping block;

[0023] A threaded groove is formed on the upper end face of the nut seat; the clamping block is rotatably equipped with a rotating rod, and the bottom of the rotating rod is provided with a threaded block that is threadedly connected to the threaded groove;

[0024] The rotating rod has a fixed plate that abuts against the bottom of the clamping block;

[0025] The bottom of the threaded block is connected to the bottom of the threaded groove by a spring.

[0026] Furthermore, the upper end face of the clamping block is movable along the length of the base plate; the end of the movable rod near the base plate is fixedly connected to the limiting block.

[0027] The surface portion of the clamping block is recessed to form a positioning groove, and the moving rod portion protrudes in the direction of the positioning groove to form a protrusion, which is inserted into the positioning groove portion;

[0028] The positioning groove is equipped with a positioning element to limit the position of the protrusion within the positioning groove.

[0029] Furthermore, the positioning components consist of several elements along the positioning plate;

[0030] The positioning plates are evenly arranged along the length of the positioning groove; wherein, the positioning plates move along the depth of the positioning groove.

[0031] The positioning plate abuts against the protrusion;

[0032] The movable pole is driven by an electric telescopic pole.

[0033] Furthermore, the welding table is also equipped with a fixing component that abuts against the upper end face of the steel bar;

[0034] The fixed components include:

[0035] The lifting platform is positioned above the steel bars;

[0036] Telescopic rods are movably installed at both ends of the lifting platform along the length of the base plate;

[0037] The contacting parts are located at both ends of the telescopic rod and abut against the surface of the steel strip;

[0038] There are two lifting platforms, both located on the first and second workstations.

[0039] Furthermore, the contact element consists of a contact plate and a rotating rod;

[0040] The contact plate is rotatably mounted at the end of the lifting plate;

[0041] In its initial position, the contact plate is inclined relative to the height extension direction of the steel strip;

[0042] The rotating rod forms a notch that abuts against the side of the steel bar; the notch forms two contact surfaces that are perpendicular to each other.

[0043] Furthermore, the surface of the contact plate is connected to the surface of the telescopic rod by a spring;

[0044] The contact plate is equipped with a sensor switch, which is electrically connected to the electric telescopic rod;

[0045] When the inductive switch senses the surface of the limit block, the electric telescopic rod is activated to move the limit block away from the steel bar.

[0046] A practical method for a multi-station automatic welding device includes the following steps:

[0047] Before use, determine the position of the steel bar base plate according to the process requirements; specifically, determine the distance between the side of the steel bar and the side of the base plate. Then, move the corresponding positioning parts so that after the limit block moves, the side wall of the limit block can coincide with the reference surface. Determine the thickness of the base plate. Twist the rotating rod to move the drive clamping block up or down so that the upper end surface of the clamping block is aligned with the base plate.

[0048] The top surface is flush with the surface.

[0049] First, place the steel bars on both sides of the base plate surface; then place the base plate on the welding table; multiple base plates can be placed at the first and second workstations at the same time; drive the rotating rod to rotate by the motor, thereby driving the two clamping blocks to move; when moving, the movement of the two clamping blocks will push the base plate to move, causing the center line of the base plate to coincide with the positioning line;

[0050] In addition, the limiting block will push the steel bar to move, so that the side of the steel bar coincides with the base surface;

[0051] The drive lifting plate moves down, aligning the notch with the side of the steel bar. As the drive plate moves down, the contact plate flips, bringing the surface of the steel bar into contact with it. At this time, the induction switch senses the surface of the limit block, causing the drive electric telescopic rod to move the limit block away from the surface of the steel bar.

[0052] Start the welding machine and begin the welding process.

[0053] The beneficial effect of this application is that it provides a multi-station automatic welding equipment with automatic positioning function. Attached Figure Description

[0079] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0080] Example 1

[0081] A multi-station automatic welding device includes: a frame 1, a welding machine body 2, and a welding table 3;

[0082] The frame 1 is formed by welding several rectangular steel pipes, and the frame 1 has a frame-like appearance. The welding machine body 2 is set on the side of the frame 1. The welding machine body 2 is an automatic welding machine that is readily available on the market. It is a limited-position technology, and the structure is not described in detail in this application. The welding machine body 2 is only used for welding flux parts. Multiple welding tables 3 are set on the frame 1 along the length direction. The welding tables 3 form a first work station a30 and a second work station a31 on both sides of the width direction of the frame 1. Therefore, one welding table 3 can weld two welding parts 100. More specifically, the welding part 100 is composed of a rectangular base plate 101 and steel bars 102 set on both sides of the length of the surface of the base plate 101. The two steel bars 102 need to be symmetrically fixed in the length direction of the base plate 101. The two sides formed by the contact between the steel bars 102 and the surface of the base plate 101 are the welding lines.

[0083] The multi-station automatic welding equipment also includes positioning components 4 located at the first station a30 and the second station a31 respectively; the positioning components 4 include two clamping blocks 40 that abut against the side wall of the base plate 101 and a limiting block 41 that abuts against the side wall of the steel bar 102; more specifically, a positioning line a40 is formed on the surface of the welding table 3 along the length of the welding table 3 and at a position that bisects both sides of the length of the welding table 3; the two clamping blocks 40 move synchronously relative to each other on the surface of the welding table 3 along the length of the frame 1 and simultaneously abut against the base plate 101 so that the center line a101 of the base plate 101 along the length of the base plate coincides with the positioning line a40; in this way, the base plate 101 can be clamped and automatically positioned at the same time by setting the two clamping blocks 40.

[0084] Specifically, the limiting block 41 moves along the length of the base plate 101 on the upper end face of the clamping block 40. This positioning block can abut against the surface of the steel strip 102 and move on the surface of the base plate 101, so that the surface of the limiting block 41 that abuts against the steel strip 102 forms a reference surface a41 for positioning the steel strip 102.

[0085] The surface of the welding station 3 is recessed to form a moving groove a32 for the two clamping blocks 40 to move; the moving groove a32 extends a portion along the length direction of the frame 1; and a limiting groove a321 is formed on the inner wall along the length direction of the moving groove a32, the limiting groove a321 being consistent with the extension direction of the moving groove a32; the two clamping blocks 40 are inserted into the two ends of the moving groove a32, and the side wall portion of the clamping block 40 protrudes and inserts into the limiting groove a321, so that the clamping block 40 is limited in the height direction of the frame 1, so that the clamping block 40 can only slide along the extension direction of the moving groove a32; wherein, the moving groove a32 is provided with a mechanism for driving the two clamping blocks 40 to move relative to each other.

[0086] More specifically, a drive rod 5 is rotatably mounted inside the moving groove a32, and two threaded grooves a51 are formed on the surface of the drive rod 5. The two threaded grooves a51 extend the same distance from both ends of the drive rod 5 towards the center position in the axial direction of the drive rod 5. The spiral directions of the two threaded grooves a51 are opposite. A nut seat 52 is fitted on the drive rod 5 and threadedly connected to the two threaded grooves a51. The clamping block 40 is movably mounted on the nut seat 52. Thus, by rotating the drive rod 5, the two clamping blocks 40 can be moved relative to each other, thereby ensuring that the centerline of the base plate 101 in the length direction coincides with the positioning line a40, and realizing the automatic positioning of the base plate 101.

[0087] More specifically, the upper end face of the nut seat 52 is recessed to form a guide hole a52; the bottom of the clamping block 40 forms a guide rod 401 for inserting into the guide hole a52; a threaded groove a51 is formed on the upper end face of the nut seat 52; the clamping block 40 is rotatably equipped with a rotating rod 402, the bottom of which is provided with a threaded block 403 threadedly connected to the threaded groove a51; the rotating rod 402 forms a fixing plate a402 that abuts against the bottom of the clamping block 40; wherein, the bottom of the threaded block 403 is connected to the bottom of the threaded groove a51 by a spring; by turning the rotating rod 402, the screw rod drives the clamping block 40 to move along the axial direction of the guide hole a52, so that the upper surface of the clamping block 40 is flush with the upper surface of the base plate 101; thus, the bottom surface of the limiting block 41 is higher than the upper end face of the base plate 101; since the clamping block 40 can move up and down, it can adapt to base plates 101 of different thicknesses, thus improving adaptability.

[0088] A movable rod 404 is movable along the length of the base plate 101 on the upper surface of the clamping block 40; the end of the movable rod 404 near the base plate 101 is fixedly connected to the limiting block 41, and the movable rod 404 is driven to move by an electronic telescopic rod; a positioning groove a404 is formed by the indentation of a portion of the surface of the clamping block 40, and a protrusion 4041 is formed by the portion of the movable rod 404 protruding in the direction of the positioning groove a404, and the protrusion 4041 is inserted into the portion of the positioning groove a404; wherein, a positioning member 42 is provided in the positioning groove a404 to limit the position of the protrusion 4041 in the positioning groove a404;

[0089] More specifically, the positioning element 42 consists of several positioning plates; the positioning groove a404 begins with a sliding groove a42 for the positioning plates to move along the depth direction of the positioning groove a404, and the side wall of the positioning plate is inserted into the sliding groove a42; the sliding groove a42 contacts the positioning plate so that the positioning plate can be limited within the sliding groove a42 by friction; furthermore, several positioning plates are evenly distributed along the direction of the sliding groove a42; moving the positioning plates at different positions causes the limiting block 41 to stop at different positions, thereby changing the position of the reference surface a41 on the base plate 101; this configuration allows the position of the steel strip 102 on the base plate 101 to be set according to different process requirements, improving adaptability;

[0090] The welding table 3 is also equipped with a fixing component 6 that abuts against the upper end face of the steel bar 102. The fixing component 6 includes: a lifting plate 61, a telescopic rod, and abutting parts.

[0091] A fixed frame 31 is formed on the surface of the welding table 3, dividing the welding table 3 into a first work station a30 and a second work station a31 along the width direction of the frame 1; two lifting plates 61 are movably set on the inner wall of the fixed frame 31, both located in the area of ​​the first work station a30 and the second work station a31; the fixed frame 31 is provided with a hydraulic cylinder for driving the lifting plates 61; telescopic rods are provided at both ends of the bottom plate 101 of the lifting plate 61 along the length direction, and the ends of the telescopic rods are provided with abutting members that abut against the upper end of the steel bar 102; the telescopic rods move according to the moving distance of the limiting block 41 so that the abutting members can always abut against the steel bar 102;

[0092] More specifically, the abutting component consists of an abutting plate 63 and a rotating shaft 62. The abutting plate 63 is rotatably mounted at the end of the lifting plate 61. In its initial position, the abutting plate 63 is inclined to the height extension direction of the steel bar 102. The rotating shaft 62 forms a notch a62 that abuts against the side of the steel bar 102. The notch a62 forms two abutting surfaces a621, which are perpendicular to each other. When the lifting plate 61 is driven to move downward, the notch a62 abuts against the side of the steel bar 102 away from the limiting block 41, and then continues to move downward, so that the surface of the abutting plate 63 abuts against the surface of the steel bar 102. Because of the notch a62, the pressing plate can continue to limit the movement when pressing against the steel bar 102, preventing the steel bar 102 from being misaligned and improving the positioning accuracy.

[0093] More specifically, the surface of the contact plate 63 is connected to the surface of the telescopic rod by a spring 631; the contact plate 63 is provided with a sensor switch 64, which is electrically connected to the electric telescopic rod 44; when the sensor switch 64 senses the surface of the limit block 41, the electric telescopic rod 44 is activated to make the limit block 41 move away from the steel bar 102; thus, the welding line is fully exposed and welding can be performed.

[0094] Example 2

[0095] Before use, the position of the steel strip 102 and the base plate 101 is determined according to the process requirements. Specifically, the distance between the side of the steel strip 102 and the side of the base plate 101 is determined. Then, the corresponding positioning component 42 is moved so that after the limiting block 41 is moved, the side wall of the limiting block 41 can coincide with the reference surface a41. The thickness of the base plate 101 is determined. The rotating rod 402 is turned to make the driving clamping block 40 move up or down so that the upper end surface of the clamping block 40 is flush with the upper end surface of the base plate 101.

[0096] First, place the steel bars 102 on both sides of the surface of the base plate 101; then place the base plate 101 on the welding table 3; multiple base plates 101 can be placed at the first station a30 and the second station a31 at one time; drive the rotating rod 402 to rotate by the motor, thereby driving the two clamping blocks 40 to move; when moving, the two clamping blocks 40 move, which will push the base plate 101 to move, so that the center line a101 of the base plate 101 coincides with the positioning line a40;

[0097] In addition, the limiting block 41 will push the steel bar 102 to move, so that the side of the steel bar 102 coincides with the base surface; drive the lifting plate 61 to move down, aligning the notch a62 with the side of the steel bar 102. When the driving plate moves down, the contact plate 63 flips and contacts the surface of the steel bar 102; at this time, the induction switch 64 senses the surface of the limiting block 41, so that the driving electric telescopic rod 44 moves the limiting block 41 away from the surface of the steel bar 102; start the welding machine body 2 to perform welding processing.

First, place the steel strip on both sides of the base plate surface. Then, place the base plate on the welding table. Multiple base plates can be placed at the first and second workstations at the same time. The rotation is driven by a motor. The rotating rod rotates, thereby driving the two clamping blocks to move. During this movement, the two clamping blocks move, pushing the base plate to move so that the center line of the base plate coincides with the positioning line. In addition, the limiting block pushes the steel bar to move, so that the side of the steel bar coincides with the base surface. The driving lifting plate moves down, aligning the notch with the side of the steel bar. When the driving plate moves down, the abutment plate flips, bringing the surface of the steel bar into contact. At this time, the inductive switch senses the surface of the limiting block, causing the driving electric telescopic rod to move the limiting block away from the surface of the steel bar. The welding machine body is then started to perform the welding process.
