Description

Technical Field

[0001] The invention relates to the technical field of stud welding equipment, and in particular to an improved welding equipment. Background Art

[0002] Stud welding is a special welding process that welds studs or columnar metals with a diameter of 2mm to 25mm on the metal surface in an efficient, low-cost, and full-section fusion manner. In the prior art, manipulator welding equipment is often used to perform short-cycle arc stud welding on workpieces that require stud welding. Specifically, first, place the welding stud (or columnar metal) on the welding parent material; then, clamp the welding stud through the welding gun and raise the height of the welding stud, and at the same time conduct the current to stimulate the arc between the welding stud and the welding parent material. The arc melts the end of the welding stud and the surface of the welding parent material and forms a welding pool; next, the welding stud and the welding parent material move relative to each other under the drive of the welding gun, and the molten end of the welding stud is inserted into the welding pool; finally, the welding gun stops running, the welding current is terminated, the arc is extinguished, and the welding pool solidifies at the same time, completing the full-section fusion weld between the welding stud and the welding parent material.

[0003] A slag ring will be formed at the welding point of the welding stud and the molten part of the welding base material. During the use of the product, the electric welding slag is easily detached and falls on the site or equipment near the weldment as the ambient temperature changes or vibrates, causing equipment failure. Therefore, after the electric welding of the welding stud is completed, the welding slag at the inner end of the welding stud needs to be removed.

[0025] The following are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.

[0026] An improved welding device, such as Figures 1 to 7As shown, the welding equipment includes a manipulator device 1 and a welding gun fixture device installed on the manipulator device 1, the welding gun fixture device is provided with a fixture disk 2, one side of the fixture disk 2 is equipped with a welding gun device 3, and the other side is equipped with a slag removal device 4, the slag removal device 4 includes a scraper drive device 41 and a slag removal tool 43, the scraper drive device 41 is installed on the fixture disk 2, the slag removal tool 43 is installed on the scraper drive device 41, and the scraper drive device 41 is connected to the slag removal tool 43 in a transmission manner; the slag removal tool 43 is provided with an inner chamber 433, the inner chamber 433 is provided with at least one stud socket positioning assembly, and the stud socket positioning assembly is provided with an inner positioning hole 440 for inserting the corresponding stud; a plug hole 430 is provided in the middle of the bottom surface of the slag removal tool 43, and the plug hole 430 is vertically connected to the inner positioning hole 440; the bottom surface of the slag removal tool 43 is provided with a cutting portion 431 or a cutter is fixed, and the cutting portion 431 or the blade of the cutter is adjacent to the plug hole 430. During slag removal, the stud to be deslaged passes through the insertion hole 430 and is inserted into the inner positioning hole 440, and the cutting part 431 of the deslag tool 43 is pressed against the welding part of the stud to realize the rotational removal of the welding slag. This welding equipment integrates welding and deslag functions, eliminating the need for manual deslag removal after the workpiece completes the stud welding process, and realizes the continuous welding process and deslag process, further shortening the product processing cycle. Among them, the important core technology is that the cylindrical deslag tool 43 can be inserted into the welding stud to rotate and remove the welding slag. During slag removal, the welding stud is inserted into the inner positioning hole 440 to avoid collision with the deslag tool 43, ensuring the coaxiality between the deslag tool 43 and the welding stud, and avoiding damage to the thread; the welding slag ring is subjected to uniform cutting force, the welding slag removal quality is good, and the welding layer structure and the external thread of the welding stud are not damaged. The problem of deslag removal of the welding stud located in the groove or hole of the workpiece is solved, and the deslag tool 43 can penetrate into the groove or hole of the workpiece to perform rotational cutting and deslag removal.

[0027] For stud welding in the slot or hole of the workpiece, the processing efficiency is significantly improved after using this improved welding equipment to replace manual welding. The specific evaluation data are shown in the following table:

[0028] Output per hour Required Personnel Defective rate Repeatability Improved welding process 30 1 0.5％ 0.02mm Manual welding 15 3 10％ 0.2mm

[0029] It can be seen from the above table that the use of this improved welding equipment to perform stud welding processing in the groove or hole of the workpiece has greatly improved the output quantity per hour, the number of operators, the defective rate and the repetition accuracy. Therefore, this welding equipment can bring obvious benefits to the enterprise and improve the enterprise's production efficiency and processing quality.

[0030] Specifically, the inner positioning hole 440 is smaller than the insertion hole 430, and the inner positioning hole 440 is in clearance with the stud; a plurality of cutting parts 431 or cutters are arranged at intervals on the outer edge of the insertion hole 430 along the circumferential direction, and the blade of the cutting part 431 or the cutter extends along the radial direction of the insertion hole 430, and the inner end of the blade does not exceed the inner wall of the insertion hole 430, and different slag removal tools 43 have inner positioning holes 440 and insertion holes 430 of different sizes. The function of the inner positioning hole 440 is to ensure the coaxiality between the slag removal tool 43 and the welding stud, so as to ensure that the welding slag ring at the root of the welding stud can be evenly removed, and the root of the stud after slag removal has a uniform cut mark, and the slag removal quality is good.

[0031] Specifically, the matching clearance between the inner positioning hole 440 and the stud is 0-0.5 mm, and the height of the cutting portion 431 or the cutting blade protruding from the bottom surface of the slag removal tool 43 is 0-5 mm.

[0032] Specifically, the bottom surface of the slag removal tool 43 is provided with a plurality of chip guide grooves 432 spaced apart in the circumferential direction, each chip guide groove 432 extends radially along the slag removal tool 43, the inner end of the chip guide groove 432 is connected to the insertion hole 430, and the outer end passes through the outer wall of the slag removal tool 43; the cross-sectional shape of the chip guide groove 432 is teardrop-shaped, and the notch of the chip guide groove 432 gradually narrows from bottom to top, and the inner side walls of the same side of each chip guide groove 432 intersect with the bottom surface of the slag removal tool 43 to form a cutting portion 431 of the same specification, and the blade angle of the cutting portion 431 is 60°-80°, and the groove edges on both sides of the same chip guide groove 432 have a height difference and form a cutting depth, and the groove edge on one side of the cutting portion 431 formed in the same chip guide groove 432 is higher than the groove edge on the other side, and the cutting depth is 0.1-0.5mm. Since the hardness of the welding slag is relatively high, the blade angle of the cutting portion 431 is set to 60° to 80° to be suitable for welding removal processing. In addition, the evenly distributed cutting portion 431 can evenly share the cutting reaction force, and the polarization of the driving axis is small, which further improves the stability of the rotary cutting slag removal and avoids accidental collision between the slag removal tool 43 and the welding stud. After the welding slag is removed, it can be guided and discharged to the outside of the slag removal tool 43 along the chip guide groove 432 to avoid gathering on the cutting surface of the slag removal tool 43 and affecting the cutting effect.

[0033] Specifically, the cutting portion 431 includes an outer blade 4312 and an inner blade 4311, the inner end of the outer blade 4312 is connected to the outer end of the inner blade 4311, and a blade angle α is formed between the outer blade 4312 and the inner blade 4311, and the blade angle α is 25° to 45°. This slag removal blade 431 with a bending angle can form a chamfer at the root of the screw after the welding part is rotated and cut to remove slag, and the edge of the welding layer will not be exposed, which is equivalent to forming a protective ring structure at the edge position between the stud and the welding base material, further improving the stability of the welding layer and improving the welding quality.

[0034] Specifically, the stud sleeve positioning assembly includes an outer fixed ring and an inner rotating ring, the outer fixed ring is fastened to the inner chamber 433, the outer fixed ring is provided with an inner mounting chamber, the inner rotating ring is rotatably mounted in the inner mounting chamber of the outer fixed ring, and an inner positioning hole 440 is provided in the middle of the inner rotating ring, and the inner positioning hole 440 vertically penetrates the inner rotating ring. The outer fixed ring and the inner rotating ring are relatively rotated to ensure that the inner positioning hole 440 has a coaxial positioning effect on the slag removal tool 43, while avoiding relative friction between the inner positioning hole 440 and the welding stud during slag removal, which causes wear on the external thread of the welding stud.

[0035] Specifically, the stud sleeve positioning assembly includes a bearing 44, which is provided with an inner bearing ring and an outer shaft seat, the outer shaft seat is fastened to the inner chamber 433, the inner bearing ring is rotatably connected to the outer shaft seat, and the inner bearing ring and the outer shaft seat are coaxially rotatably matched; the inner bearing ring has an inner shaft hole that passes through the inner bearing ring up and down to form an inner positioning hole 440, and the slag removal tool 43 is inserted into the stud through the plug hole before the rotary cutting slag removal, and the inner bearing ring of the bearing 44 is sleeved on the stud, and the inner shaft hole and the stud have a clearance fit. The centripetal bearing 44 is used as the above-mentioned stud sleeve positioning assembly, which is low in cost and easy to select and match. Its low eccentricity can ensure the coaxiality between the slag removal tool 43 and the welding stud, and smoothly complete the rotary cutting slag removal of the welding stud.

[0036] Specifically, the slag removal device 4 is also provided with a tool handle 42, one side of the tool handle 42 is provided with a connecting shaft 421, and the other side is provided with a tool assembly part, the scraper drive device 41 has an output shaft, and the connecting shaft 421 is connected to the output shaft of the scraper drive device 41; the slag removal tool 43 is installed on the tool assembly part of the tool handle 42. The slag removal tool 43 is a replaceable component, and the slag removal tool 43 adapted to different length specifications, diameter and width specifications and workpiece opening sizes can be replaced.

[0037] Two or more bearings 44 are fixed in the inner chamber 433. The bearings 44 are coaxially matched with each other. The matching clearance between the inner shaft hole of each bearing 44 and the stud is less than 0.1mm. When rotating and cutting to remove slag, the bottom surface of the slag removal tool 43 is pressed against the root of the stud. The inner shaft hole of each bearing 44 is respectively sleeved on the stud. The inner bearing ring and the outer shaft seat are relatively rotated and matched. The inner bearing ring and the stud are relatively static in the rotation direction and relatively displaced in the vertical direction to avoid damage to the stud and ensure the coaxiality between the slag removal tool 43 and the stud. The stud insertion and positioning assembly composed of multiple overlapping bearings 44 can ensure that the slag removal tool 43 maintains a relatively high coaxiality with the stud when it is inserted into the stud, so that the cutting part can be evenly pressed against the welding slag ring in the circumferential direction. In addition, the radial load on the bolt is reduced to avoid damage to the thread.

[0038] Specifically, a cylindrical boss 422 is provided in the middle of the tool assembly part. During assembly, the boss 422 is movably inserted into the inner chamber 433 and the table surface of the boss 422 abuts against a radial bearing 44 close thereto. The stud sleeve positioning assembly is a sleeve positioning functional part. The assembly coaxiality between the stud sleeve positioning assembly and the slag removal tool 43 is one of the keys to whether the rotary cutting slag removal is smooth or not. This tool assembly part can ensure that the slag removal tool 43 is highly coaxial with the output shaft of the scraper drive device 41 during assembly, so that the slag removal tool 43 maintains a relatively high coaxiality with the stud when it is inserted into the stud, and the cutting part can be evenly pressed against the welding slag ring in the circumferential direction. In addition, the radial load on the bolt is reduced to avoid damage to the thread.

[0039] Specifically, the boss surface of the boss 422 is provided with a gasket 423 for resisting the outer ring of the radial bearing 44. The gasket 423 is made of soft rubber material to prevent the inner ring of the radial bearing 44 from pressing against the boss surface of the boss 422 to generate friction resistance, resulting in relative friction between the inner ring and the surface of the stud and damaging the thread.

[0040] Specifically, the tool handle 42 is provided with at least two fastening connection holes 420 spaced apart in the circumferential direction, each fastening connection hole 420 is inserted with a fastening bolt 424, and the assembly surface of the slag removal tool 43 is provided with threaded holes 434 having the same number as the fastening bolts 424. During assembly, the assembly surface of the slag removal tool 43 is tightly fitted with the outer side surface of the tool handle 42, and each fastening bolt 424 is threadedly connected to the corresponding threaded hole 434.

[0042] Specifically, the articulated manipulator includes a manipulator base 11, a mechanical arm 12 rotatably mounted on the manipulator base 11, a mechanical elbow 13 rotatably connected to the mechanical arm 12, and a mechanical elbow wrist 14 rotatably connected to the mechanical elbow 13, and a rotary shaft joint 15 mounted on the mechanical elbow wrist 14, which together form a six-axis manipulator to cooperate with and drive the welding gun device 3 and the slag removal device 4 to move to the target processing position respectively, and have the characteristics of high transmission efficiency, fast torsion speed, and precise positioning. In addition, the articulated manipulator can be freely programmed, and the control system program of the articulated manipulator has the functions of editing, modifying and memorizing. Through the set program, the fully automated work can be completed, completely replacing manual work, improving production efficiency, and strictly controlling the qualified rate.

[0043] Of course, the manipulator device 1 can also be set as a rectangular coordinate manipulator, which is provided with at least two linear servo modules vertically arranged to each other, and the linear servo module is provided with a linear drive seat. The tooling disk 2 is installed on the linear drive seat of any one of the linear servo modules, and the welding gun device 3 and the slag removal device 4 are transposed in the linear direction.

When the welding equipment is in the welding mode, the tooling disk 2 drives the welding gun device 3 to move along the linear direction to the set target processing position to complete the stud welding; when the welding equipment is in the slag removal mode, the tooling disk 2 drives the slag removal device 4 to move along the linear direction to the same target processing position to complete the welding slag removal.

[0044] like Figure 8 As shown, specifically, the rotary shaft joint 15 is provided with a quick-change tooling disk structure, including a plug-in port 150 opened at the outer end of the rotary shaft joint 15 and oil pressure pins evenly distributed in the opposite direction of the circumference, the oil pressure pins are radially arranged, and the oil pressure pins are connected to a hydraulic drive device; a connecting column 21 is provided at the bottom of the tooling disk 2, and a plurality of pin holes are opened on the circumferential surface of the connecting column 21. During assembly, the connecting column 21 is inserted into the plug-in port 150, and the hydraulic drive device drives the oil pressure pins to be inserted inward into the corresponding pin holes to lock the tooling disk 2.

[0045] Specifically, the outer wall of the rotating shaft joint 15 is provided with a hydraulic transmission structure, which includes a hydraulic cylinder 153 provided on the circumference of the rotating shaft joint 15 and a slider 154 slidably provided in the hydraulic cylinder 153. The hydraulic latch is fixedly connected to the inner side of the slider 154. The outer side surface of the slider 154 and the inner cavity of the hydraulic cylinder 153 surround to form a first hydraulic chamber. The inner side surface of the slider 154 and the inner cavity of the hydraulic cylinder 153 surround to form a second hydraulic chamber. The first hydraulic chamber is provided with a first interface 151, and the second hydraulic chamber is provided with a second interface 152. Port 152, the hydraulic drive device is respectively connected to the first port 151 and the second port 152.

[0046] This tooling tray structure enables rapid replacement of the tooling tray 2, shortens the replacement cycle, eliminates tooling correction, improves production efficiency, and accurately positions to ensure processing accuracy.

[0047] The present invention also provides a stud welding processing method, comprising the following steps:

[0048] 1) Place the welding stud at the target processing position of the welding base material (the target processing position is a slot or hole).

[0049] 2) The welding gun device 3 is driven to move to the target processing position by the manipulator device 1 of the welding equipment, and arc welding is performed on the welding stud.

[0050] 3) After arc welding is completed, the manipulator device 1 drives the tooling disc 2 to rotate or move linearly, so that the slag removal device 4 and the welding gun device 3 assembled on the same tooling disc 2 are exchanged, and the switching time is controlled to be 1 second to 5 seconds.

[0051] 4) The robot device 1 drives the slag removal tool 43 of the slag removal device 4 to be inserted into the welding stud and inserted into the groove or hole of the target processing position. The welding stud passes through the insertion hole 430 of the slag removal tool 43 and is movably inserted into the inner positioning hole 440 of the stud sleeve positioning assembly of the slag removal tool 43.

[0052] 5) Start the scraper driving device 41 of the slag removal device 4 to perform rotational cutting and slag removal on the welding part of the welding stud, and keep the slag removal tool 43 always having a movement trend towards the root of the welding stud. The inner positioning hole 440 of the stud sleeve positioning assembly in the slag removal tool 43 and the welding stud are relatively stationary in the rotation direction to complete the stud welding process.

[0053] The technical points of this stud welding processing method are: 1.

After the arc welding is completed, the welding slag still has residual heat, low hardness, soft texture, easy to remove, less reaction force on the slag removal knife, long service life of the slag removal knife, and good slag removal effect, not easy to damage the welding layer structure; 2) The welding part of the welding stud is rotated and cut to remove slag by a cylindrical cutting tool, which solves the problem of cleaning the welding slag of the stud in the hole or groove. The welding slag removal quality is good, does not damage the welding layer structure, has a low scrap rate, and improves the enterprise efficiency; 3) The inner positioning hole 440 of the stud sleeve positioning assembly is used to ensure the coaxiality between the slag removal tool 43 and the welding stud during the rotation cutting process, reduce rotational polarization, and improve the slag removal quality.
