Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a device and method for welding crusher teeth for cement pavement. Background Technology

[0002] Cement pavement crushers are core equipment for old road renovation and municipal maintenance, specifically designed for crushing rigid pavements such as concrete and cement-stabilized layers. Powered by a diesel engine or electric motor, the machine body is equipped with multiple rows of wear-resistant alloy crushing teeth arranged in a spiral pattern. Through high-speed rotation or impact, it breaks down entire cement pavements into uniform fragments. The crushing process does not damage the roadbed structure, and the fragments can be directly recycled as aggregate, combining environmental protection and economic efficiency.

[0003] Referring to the patent application with publication number CN117506278A, a crusher tooth disc repair and welding device is disclosed. The crusher tooth disc repair and welding device includes: a rotating component, including a housing, a rotating assembly disposed on one side of the housing, a driving assembly disposed on the rotating assembly, a limiting assembly disposed on one side of the housing, and a fixing assembly disposed on the limiting assembly.

[0004] Existing crusher teeth are mostly arranged in a spiral pattern. Traditional clamps can only position and weld single teeth. Changing the tooth position requires repeated adjustment of the clamp position, which not only prolongs the welding time of a single crusher tooth, but also easily leads to large deviations in the inter-tooth spacing during clamp position adjustment, affecting assembly accuracy. At the same time, the adaptability of welding equipment clamps is poor, and they cannot be compatible with different specifications of wide teeth. Changing the tooth shape requires custom-made clamps. For example, the existing technology mentioned above only fixes the tooth disk to be repaired in the clamping component, and rotates the limiting component to drive the relevant components to rotate the tooth disk to the appropriate angle and fix it, which is convenient for operators to weld various bucket teeth. However, since the crusher teeth are spirally distributed on the tooth disk body, the position of the clamping component needs to be readjusted after welding a single tooth. The repeated adjustment of the clamping component position not only increases the probability of positioning errors of the crusher teeth, but also requires repeated adjustment of the clamping component position when welding multiple crusher teeth at the same time, which significantly increases the welding time and makes it unsuitable for welding batches of crusher teeth.

[0005] Therefore, the present invention proposes a device and method for welding crusher teeth for cement pavement to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a welding device and method for crusher teeth used in cement pavement. It solves the problems of existing crusher teeth being mostly spirally arranged, traditional clamps only allowing for single-tooth positioning and welding, and the need to repeatedly adjust the clamp position when switching tooth positions. This not only prolongs the welding time for a single crusher tooth, making it unsuitable for welding batches of crusher teeth, but also easily leads to large deviations in tooth spacing during clamp position adjustments, affecting assembly accuracy. Furthermore, the welding equipment clamps have poor adaptability, cannot accommodate different specifications of wide teeth, and require custom-made clamps to be used when changing tooth shapes.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a welding device for crusher teeth in cement pavement, comprising a welding table and a rotary drive motor fixedly disposed therein, the output shaft of the rotary drive motor rotating through the welding table and a turntable fixedly disposed therein, and further comprising: The welding position control component is set on the top of the turntable and rotates synchronously. It is used to support the crusher teeth to be welded and to simultaneously adjust the position of the crusher teeth from the center of the welding position control component in multiple directions. Multiple positioning mechanisms are evenly arranged around the welding position control component to clamp the crusher teeth to be welded. Before welding, the spiral distribution trajectory of multiple crusher teeth is simulated in advance, and the position of the crusher teeth is further fine-tuned in the horizontal and vertical directions to accurately position the crusher teeth before welding. An angle adjustment mechanism is set at the top center of the welding position control component. The top of the mechanism is used to place the crushing roller assembly to be welded. The angle adjustment mechanism can drive the crushing roller assembly to rotate axially, so as to facilitate the rapid calibration and positioning of the welding points on the surface of the crushing roller assembly and the crusher teeth to be welded. The welding mechanism includes a linear module fixedly mounted on one side of the welding table, and an arc welding robot is mounted on the top of the linear module. The arc welding robot can move left and right under the drive of the linear module. The controller is fixedly installed on one side of the top of the welding table and is used to control the operation of all electrical equipment.

[0008] Furthermore, the welding position control component includes a tray fixedly mounted on the top of the turntable, and a protective cover is also fixedly mounted on the top of the tray. The top of the protective cover has a plurality of clearance slots evenly distributed, and a first servo motor is fixedly mounted at the center of the top of the protective cover. The output shaft of the first servo motor rotates through the protective cover and is fixedly mounted on a drive disk. The top of the drive disk has arc-shaped drive slots that correspond one-to-one with the positions of the plurality of clearance slots.

[0009] Furthermore, the positioning mechanism includes a sliding sleeve fixedly mounted on the top of the tray and a sliding block slidably mounted inside the sliding sleeve. A slider is fixedly mounted on one side of the top of the sliding block, and a vertical rod is also fixedly mounted on the top of the sliding block. An upper clamping arm assembly and a lower clamping arm assembly for clamping crusher teeth are symmetrically arranged on the upper and lower sides of the outer wall of the vertical rod. The outer wall of the vertical rod is also provided with scale grooves for marking the positions of the upper clamping arm assembly and the lower clamping arm assembly. Furthermore, the upper clamping arm assembly includes a lifting sleeve slidably sleeved on the outer wall of the vertical rod. The lifting sleeve is locked in position by a first locking bolt and the vertical rod. A side plate is also fixedly installed on the outer wall of the lifting sleeve. Sliding grooves are opened on both sides of the side wall of the side plate. Adjusting slides are slidably installed in both sliding grooves. The two adjusting slides are locked in position by positioning bolts and the side plate. A laser rangefinder is fixedly installed in the middle of the side wall of the side plate. A first clamping arm unit and a second clamping arm unit are provided on the adjusting slide.

[0010] Furthermore, the first clamping arm unit includes a telescopic arm sleeve fixedly mounted on an adjusting slide block. An extension arm is slidably mounted inside the telescopic arm sleeve. Marking grooves for marking the extension length of the extension arm are evenly provided on the outer wall of the telescopic arm sleeve. A rotating seat is rotatably mounted at the end of the extension arm. The rotating seat and the extension arm are locked in position by a positioning bolt. A rotating block is rotatably connected inside the rotating seat. A clamping sleeve is fixedly mounted on the rotating block. A V-shaped clamping seat is provided inside the clamping sleeve. A second fastening bolt for locking the crusher teeth in conjunction with the V-shaped clamping seat is threaded onto the outer wall of the clamping sleeve.

[0011] Furthermore, the angle adjustment mechanism includes a support seat fixedly installed at the center of the top of the protective cover. A crosshair is provided at the center of the support seat to facilitate the placement of the crushing roller assembly. The support seat has a hollow structure inside and a circular through groove at its bottom. An annular groove is provided on the inner wall of the support seat. A toothed ring is rotatably connected to the annular groove. A support plate is fixedly installed on the top of the toothed ring and inside the circular through groove. A second servo motor is fixedly installed on one side inside the support seat. A gear is fixedly installed on the output shaft of the second servo motor. The gear meshes with the toothed ring for transmission.

[0012] Furthermore, the structure of the lower clamping arm assembly is exactly the same as that of the upper clamping arm assembly, and the upper clamping arm assembly and the lower clamping arm assembly are symmetrically distributed along the axis of the vertical rod.

[0013] Furthermore, the laser rangefinder is directed towards the crusher tooth body to detect the distance between the crusher tooth body and the welding position in real time and feed it back to the controller.

[0014] Furthermore, the crushing roller assembly includes a carrying roller and a first spiral crusher tooth group and a second spiral crusher tooth group symmetrically arranged on both sides of the outer wall of the carrying roller. The first spiral crusher tooth group and the second spiral crusher tooth group have the same structure. The first spiral crusher tooth group includes a tooth seat welded to the outer wall of the carrying roller, on which the crusher tooth body is fixedly disposed.

[0015] This invention also discloses a method for welding crusher teeth for cement pavement, employing a crusher tooth welding device for cement pavement, and the method includes the following steps: Step 1: First, control multiple positioning mechanisms to move synchronously away from the center position of the angle adjustment mechanism through the controller, and then place the crushing roller assembly to be welded at the center position of the top of the angle adjustment mechanism; Step 2: Next, clamp the crusher teeth to be welded onto the positioning mechanism, and then control the angle adjustment mechanism to rotate through the controller to fine-tune the position of the crushing roller assembly. Then, further adjust the up-down and left-right positions of the crusher teeth to be welded on the positioning mechanism to ensure that the welding points on the crushing roller assembly and the positions of the crusher teeth on the positioning mechanism are relative. Step 3: Based on the outer diameter of the crushing roller assembly to be welded and the distance between the center positions of the positioning mechanism and the angle adjustment mechanism, the welding position adjustment component is adjusted again by the controller so that multiple positioning mechanisms move closer to each other synchronously, so as to ensure that the multiple crusher teeth to be welded are exactly opposite to the welding points on the outer wall of the crushing roller assembly. Step 4: Using an arc welding robot, the crusher teeth are welded to the corresponding welding points on the outer wall of the crushing roller assembly using arc welding.

[0016] This invention provides a device and method for welding crusher teeth for cement pavement. Compared with the prior art, it has the following advantages: 1. A device and method for welding crusher teeth for cement pavement, which uses multiple positioning mechanisms evenly arranged around a welding position control component to simultaneously clamp multiple crusher teeth to be welded, eliminating the need for "welding one, disassembling one, and then installing the next" as in traditional equipment, directly reducing the number of repetitive feeding and positioning operations per tooth; secondly, the cooperation between the welding position control component and the positioning mechanisms allows for the pre-simulation of the spiral arrangement trajectory of multiple crusher teeth before welding, eliminating the need for repeated tooth position corrections during welding, further compressing the work cycle. Compared to traditional single-tooth welding methods, this device significantly improves the welding efficiency per batch, making it particularly suitable for mass production scenarios; in addition, a rotary drive motor drives a turntable to rotate synchronously, which, in conjunction with a linear module driving an arc welding robot to move left and right, forms a continuous operation mode of "rotary feeding plus translational welding," that is, when the previous crusher tooth is welded, the next precisely positioned tooth is simultaneously delivered to the welding position without stopping the machine for adjustment, greatly improving welding efficiency and welding accuracy.

[0017] 2. A crusher tooth welding device and method for cement pavement, which has a triple fine-tuning capability for the crusher teeth in terms of "up and down, left and right, and axial angle" through a positioning mechanism. That is, the lifting sleeve slides along the vertical rod to achieve up and down adjustment, the adjusting slide slides along the slide groove to achieve left and right adjustment, and the rotating block rotates along the rotating seat to achieve angle fine-tuning, ensuring that the welding surface of each tooth is completely in contact with the tooth seat; secondly, a laser rangefinder detects the distance between the welding end of the crusher tooth and the outer wall of the bearing roller in real time and feeds the data back to the controller, avoiding errors caused by manual visual inspection. At the same time, it helps to judge whether the spacing between the spirally arranged teeth is uniform, changing from "passive adjustment" to "active calibration", which greatly improves the positioning accuracy of the crusher teeth.

[0018] 3. A welding device and method for crusher teeth in cement pavement, wherein the clamping width can be adjusted according to the cross-sectional dimensions of the crusher teeth by cooperating with the V-shaped clamping seat and the second fastening bolt in the positioning mechanism. The V-shaped structure is suitable for teeth with different cross-sections such as round, square, and trapezoidal, avoiding the limitation that a single clamp can only clamp one type of tooth. Secondly, the extension length of the clamping end can be adjusted by the relative sliding of the telescopic arm sleeve and the extension arm to adapt to crusher teeth with different tooth lengths. Combined with the height adjustment of the lifting sleeve, it can adapt to the welding requirements of different tooth heights without the need to replace the clamping components.

The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0022] 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.

[0023] This invention provides three technical solutions: a crusher tooth welding device for cement pavement, specifically including the following embodiments: like Figures 1-8The first embodiment is shown: a welding device for crusher teeth of cement pavement, including a welding table 1 and a rotary drive motor fixedly installed therein, the output shaft of the rotary drive motor rotating through the welding table 1 and a turntable 2 fixedly installed thereon, and further including: The welding position control component is set on the top of the turntable 2 and rotates synchronously. It is used to support the crusher teeth to be welded and to synchronously adjust the position of the crusher teeth from the center of the welding position control component in multiple directions. Multiple positioning mechanisms 9 are evenly arranged around the welding position adjustment component to clamp the crusher teeth to be welded. Before welding, the spiral distribution trajectory of multiple crusher teeth is simulated in advance, and the position of the crusher teeth is further fine-tuned in the horizontal and vertical directions to accurately position the crusher teeth before welding. When the multiple positioning mechanisms 9 are in the initial position, the distance between each clamping sleeve 9575 and the center position of the angle adjustment mechanism 10 is the same and is a known value.

[0024] An angle adjustment mechanism 10 is set at the top center of the welding position control component. Its top is used to place the crushing roller assembly 14 to be welded. The angle adjustment mechanism 10 can drive the crushing roller assembly 14 to rotate axially, so as to facilitate the rapid calibration and positioning of the welding points on the surface of the crushing roller assembly 14 and the crusher teeth to be welded. The welding mechanism includes a linear module 11 fixedly mounted on one side of the welding table 1, and an arc welding robot 12 mounted on the top of the linear module 11. The arc welding robot 12 can move left and right under the drive of the linear module 11. The controller 13 is fixedly installed on one side of the top of the welding table 1 and is used to control the operation of all electrical equipment.

[0025] In this embodiment, the welding position control component includes a tray 3 fixedly mounted on the top of the turntable 2. A protective cover 4 is also fixedly mounted on the top of the tray 3. A plurality of clearance slots 5 are evenly provided on the top of the protective cover 4. A first servo motor 6 is fixedly mounted at the center of the top of the protective cover 4. The output shaft of the first servo motor 6 rotates through the protective cover 4 and is fixedly mounted on a drive disk 7. The top of the drive disk 7 is evenly provided with arc-shaped drive slots 8 that correspond one-to-one with the positions of the plurality of clearance slots 5.

[0026] like Figures 9-11The second embodiment is shown, which differs from the first embodiment in that: the positioning mechanism 9 includes a sliding sleeve 91 fixedly disposed on the top of the tray 3 and a sliding base 92 slidably disposed inside the sliding sleeve 91. A slider 93 is fixedly disposed on one side of the top of the sliding base 92, and a vertical rod 94 is also fixedly disposed on the top of the sliding base 92. The upper and lower sides of the outer wall of the vertical rod 94 are symmetrically provided with an upper clamping arm assembly 95 and a lower clamping arm assembly 96 for clamping the crusher teeth. The outer wall of the vertical rod 94 is also provided with a scale groove 97 for marking the positions of the upper clamping arm assembly 95 and the lower clamping arm assembly 96. The slider 93 is simultaneously slidably disposed in the arc-shaped drive groove 8 and the clearance groove 5 at opposite positions, so that the slider 93 slides along the clearance groove 5 at the corresponding position under the drive of the arc-shaped drive groove 8.

[0027] In this embodiment, the upper clamping arm assembly 95 includes a lifting sleeve 951 slidably sleeved on the outer wall of the vertical rod 94. The lifting sleeve 951 is locked in position by the vertical rod 94 through a first locking bolt 952. A side plate 953 is also fixedly provided on the outer wall of the lifting sleeve 951. Slide grooves 954 are provided on both sides of the side wall of the side plate 953. Adjusting slide blocks 956 are slidably provided in both slide grooves 954. The two adjusting slide blocks 956 are locked in position by positioning bolts and the side plate 953. A laser rangefinder 955 is fixedly provided in the middle of the side wall of the side plate 953. A first clamping arm unit 957 and a second clamping arm unit 958 are provided on the adjusting slide block 956. The first clamping arm unit 957 includes a telescopic arm sleeve 9571 fixedly mounted on an adjusting slide block 956. An extension arm 9572 is slidably mounted inside the telescopic arm sleeve 9571. Marking grooves for marking the extension length of the extension arm 9572 are evenly distributed on the outer wall of the telescopic arm sleeve 9571. A rotating seat 9573 is rotatably mounted at the end of the extension arm 9572. The rotating seat 9573 and the extension arm 9572 are locked in position by a positioning bolt. A rotating block 9574 is rotatably connected inside the rotating seat 9573. A clamping sleeve 9575 is fixedly mounted on the rotating block 9574. A V-shaped clamping seat 9576 is provided inside the clamping sleeve 9575. A second fastening bolt 9577 is threadedly connected to the outer wall of the clamping sleeve 9575 for locking the crusher teeth in conjunction with the V-shaped clamping seat 9576. The second clamping arm unit 958 has the same structure as the first clamping arm unit 957.

[0028] like Figure 12-14A third embodiment is shown, differing from the second embodiment in that: the angle adjustment mechanism 10 includes a support base 101 fixedly disposed at the top center of the protective cover 4. A crosshair is provided at the center of the support base 101 for facilitating the placement of the crushing roller assembly 14. The support base 101 has a hollow interior and a circular through-groove at its bottom. An annular groove is formed on the inner wall of the support base 101, and a gear ring 102 is rotatably connected to the annular groove. A support plate 103 is fixedly disposed on the top of the gear ring 102, located inside the circular through-groove. A second servo motor 104 is fixedly disposed on one side of the interior of the support base 101. A gear 105 is fixedly disposed on the output shaft of the second servo motor 104, and the gear 105 meshes with the gear ring 102 for transmission. The support plate 103 is used to place the bearing roller 141. The structure of the lower clamping arm assembly 96 is identical to that of the upper clamping arm assembly 95, and the upper clamping arm assembly 95 and the lower clamping arm assembly 96 are symmetrically distributed along the axis of the vertical rod 94. The laser rangefinder 955 is directed toward the crusher tooth body 143 and is used to detect the distance between the crusher tooth body 143 and the welding position in real time and feed it back to the controller 13.

[0029] In this embodiment, the crushing roller assembly 14 includes a support roller 141 and a first spiral crusher tooth group and a second spiral crusher tooth group symmetrically arranged on both sides of the outer wall of the support roller 141. A toothed ring for connecting with the transmission structure of the cement pavement crushing equipment is fixedly arranged between the first spiral crusher tooth group and the second spiral crusher tooth group. The first spiral crusher tooth group and the second spiral crusher tooth group have the same structure. The first spiral crusher tooth group includes a tooth seat 142 welded to the outer wall of the support roller 141, and a crusher tooth body 143 is fixedly arranged on the tooth seat 142. The multiple tooth seats 142 are spirally distributed, and the spacing between two adjacent crusher tooth bodies 143 is the same.

[0030] The present invention also provides a method for welding crusher teeth for cement pavement, employing a crusher tooth welding device for cement pavement, the method comprising the following steps: Step 1: First, control multiple positioning mechanisms 9 to move away from the center position of the angle adjustment mechanism 10 synchronously through the controller 13, and then place the crushing roller assembly 14 to be welded at the center position of the top of the angle adjustment mechanism 10. The initial clearance adjustment controller 13 of the positioning mechanism 9 first sends a command to the welding position control component: start the first servo motor 6 fixed at the top center of the protective cover 4, whose output shaft drives the drive disk 7 through the protective cover 4 to rotate by a preset angle. Since the arc-shaped drive groove 8 at the top of the drive disk 7 slides and engages with the slider 93 of the positioning mechanism 9, and the slider 93 is simultaneously fitted into the clearance groove 5 of the protective cover 4, the rotation of the drive disk 7 will push the slider 93 to slide outward along the clearance groove 5 through the arc-shaped drive groove 8. The slider 93 is fixedly connected to the slide seat 92 of the positioning mechanism 9, and the slide seat 92 is slidably fitted into the slide sleeve 91 at the top of the tray 3. Therefore, the outward sliding of the slider 93 will drive the slide seat 92 to move outward synchronously along the slide sleeve 91, so that the vertical rod 94 at the top of the slide seat 92 and the upper clamping arm assembly 95 and lower clamping arm assembly 96 on the vertical rod 94 are moved away from the center of the angle adjustment mechanism 10, leaving enough space for the subsequent placement of the crushing roller assembly 14 to be welded.

[0031] The precise placement of the crushing roller assembly 14 involves smoothly placing the crushing roller assembly 14 to be welded onto the support plate 103 of the angle adjustment mechanism 10. The support plate 103 is fixed to the top of the toothed ring 102, which is rotatably connected to the support seat 101, ensuring that the bearing roller 141 can rotate synchronously with the support plate 103 after placement, and that its center coincides with the center of the angle adjustment mechanism 10.

[0032] Step 2: Next, clamp the crusher teeth to be welded onto the positioning mechanism 9, and then control the angle adjustment mechanism 10 to rotate through the controller 13 to fine-tune the position of the crushing roller assembly 14. Then, further adjust the up-down and left-right positions of the crusher teeth to be welded on the positioning mechanism 9 to ensure that the welding points on the crushing roller assembly 14 and the positions of the crusher teeth on the positioning mechanism 9 are relative. The stable clamping of the crusher tooth body 143 involves placing the crusher tooth body 143 to be welded into the clamping structure of the positioning mechanism 9: opening the V-shaped clamping seat 9576 of the upper clamping arm assembly 95 and the lower clamping arm assembly 96, placing the non-welded end of the crusher tooth body 143 into the V-groove, and pushing the V-shaped clamping seat 9576 to tighten in the clamping sleeve 9575 by tightening the second fastening bolt 9577, thus achieving the initial fixation of the crusher tooth body 143; the clamping sleeve 9575 is rotatably connected to the rotating seat 9573 through the rotating block 9574, and the rotating seat 9573 rotates at the end of the extension arm 9572, reserving freedom for subsequent angle fine adjustment.

[0033] The angle fine-tuning controller 13 of the bearing roller 141 starts the second servo motor 104 of the angle adjustment mechanism 10, and its output shaft drives the gear 105 to rotate. Since the gear 105 meshes with the gear ring 102, the gear ring 102 will drive the bearing plate 103 and the top bearing roller 141 to rotate slowly axially until the welding point on the outer wall of the bearing roller 141 faces the positioning mechanism 9, thus completing the position calibration of the bearing roller end.

[0034] Then, loosen the first locking bolts 952 of the upper clamping arm assembly 95 and the lower clamping arm assembly 96, and determine the lifting distance of the sliding lifting sleeve 951 on the vertical rod 94 by referring to the scale groove 97 on the outer wall of the vertical rod 94. After the welded end of the crusher tooth body 143 is aligned with the height of the tooth seat 142, tighten the first locking bolts 952 to lock the lifting sleeve 951.

[0035] Next, the sliding adjustment slide 956 is positioned within the groove 954 of the side plate 953, and the laser rangefinder 955 on the side plate 953 is activated to detect the distance between the welded end of the crusher tooth body 143 and the outer wall of the bearing roller 141 in real time. At the same time, the distance is referenced to the marked groove on the outer wall of the telescopic arm sleeve 9571, and the data is fed back to the controller 13. The controller 13 guides the adjustment of the sliding direction of the slide 956 according to the feedback value until the crusher tooth body 143 and the tooth seat 142 are initially aligned in the horizontal direction.

[0036] If there is an angular deviation, the angle of the rotating block 9574 within the rotating seat 9573 can be rotated to drive the crusher tooth body 143 within the clamping sleeve 9575 and the V-shaped clamping seat 9576 to rotate, ensuring that its welding surface is completely in contact with the tooth seat 142.

[0037] Step 3: Based on the outer diameter of the crushing roller assembly 14 to be welded and the distance between the center positions of the positioning mechanism 9 and the angle adjustment mechanism 10, the welding position adjustment component is adjusted again by the controller 13 so that multiple positioning mechanisms 9 move closer to each other synchronously, so as to ensure that multiple crusher teeth to be welded are exactly opposite to the welding points on the outer wall of the crushing roller assembly 14. The positioning mechanism 9 moves closer to the adjustment controller 13. Based on the outer diameter of the bearing roller 141 and the center distance between the positioning mechanism 9 and the angle adjustment mechanism 10, the controller sends a reverse rotation command to the first servo motor 6: the drive disk 7 rotates in the reverse direction, the arc-shaped drive groove 8 drives the slider 93 to slide inward along the avoidance groove 5, and the slide block 92 moves inward synchronously along the slide sleeve 91, so that the vertical rod 94 and the positioning mechanism 9 move closer to the center of the angle adjustment mechanism 10, thereby reducing the distance between the crusher tooth body 143 and the bearing roller 141.

[0038] For a single positioning mechanism 9, the local telescopic fine-tuning is achieved by adjusting the relative sliding of the telescopic arm sleeve 9571 and the extension arm 9572 of the first clamping arm unit 957 to fine-tune the extension length of the extension arm 9572. At the same time, combined with the real-time detection data of the laser rangefinder 955, it is ensured that the crusher tooth body 143 on multiple positioning mechanisms 9 is arranged according to the preset spiral distribution trajectory, and the welded end of each crusher tooth body 143 is precisely aligned with the tooth seat 142 corresponding to the outer wall of the bearing roller 141 to avoid deviation in the tooth spacing.

[0039] Step 4: The crusher teeth are welded to the corresponding welding points on the outer wall of the crushing roller assembly 14 by the arc welding robot 12 using the arc welding method.

[0040] The rotary drive motor inside the welding table 1 is started, and its output shaft drives the turntable 2 that runs through the welding table 1 to rotate at a constant speed. The tray 3 fixed on the top of the turntable 2 rotates synchronously with the turntable 2, thereby driving the protective cover 4, the positioning mechanism 9 and the crusher tooth body 143 to rotate as a whole, so that each crusher tooth body 143 aligned with the tooth seat 142 enters the welding range of the arc welding robot 12 in sequence.

[0041] Start the linear module 11, which drives the top arc welding robot 12 to move left and right in the horizontal direction. In conjunction with the rotation of the turntable 2, it achieves welding coverage of the crusher teeth at different spiral positions.

[0042] The arc welding robot 12 performs arc welding on the crusher tooth body 143 and tooth holder 142, which are rotated into the welding range, according to the welding parameters of current, voltage and welding speed preset by the controller 13. The high temperature generated by the arc melts and fuses the welding ends of the two to form a strong welded joint. After one crusher tooth is welded, the turntable 2 continues to rotate and sends the next crusher tooth body 143 aligned with the tooth holder 142 to the welding position until all crusher teeth are welded on the tooth holder 142 of the bearing roller 141, thus completing the entire welding operation.
