Description

Technical Field

[0001] This utility model relates to the field of narrow lap welding machine maintenance technology, and in particular to an auxiliary tooling for the maintenance of the electrode head of the welding wheel of a narrow lap welding machine. Background Technology

[0002] Currently, in narrow lap weld processes, rolling electrodes are used instead of traditional spot-welding cylindrical electrodes. During welding, a pair of rotating welding wheel electrodes press the workpiece against it, causing the workpiece to move continuously between the welding wheels, thus forming an lap weld nugget and ultimately creating a sealed weld joint. However, existing fixed fixtures have significant efficiency issues in the electrode head maintenance process. The traditional solution is to directly connect the electrode head to the maintenance platform using bolts. This method requires a considerable amount of time to tighten the bolts during maintenance and installation; similarly, the disassembly process after maintenance is also very inefficient. This situation directly reduces the turnover efficiency of the electrode head between maintenance and production use, thus affecting the overall utilization rate of the equipment. Therefore, there is an urgent need for a new type of auxiliary fixture that can solve the problem of low electrode head maintenance efficiency in existing technologies. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides an auxiliary tooling for maintaining the electrode head of a narrow lap welding machine welding wheel, such as... Figures 1-4As shown, the assembly includes: a first mounting plate 1, a height adjustment mechanism, a second mounting plate 7, a main support plate 5, a clamping mechanism, and a lifting drive mechanism. The first mounting plate 1 is mounted on the welding workbench; the height adjustment mechanism is mounted on the first mounting plate 1; the second mounting plate 7 is mounted on the lifting end of the height adjustment mechanism to rise or fall under the drive of the height adjustment mechanism and maintain the position after lifting or falling; the main support plate 5 is mounted above the second mounting plate 7 to place the electrode head body 4; the clamping mechanism includes a first clamping plate 30 and a second clamping plate, both of which are slidably connected to the main support plate 5; the lifting drive mechanism is mounted on the second mounting plate 7, and the lifting drive end of the lifting drive mechanism is connected to the first clamping plate 30 and the second clamping plate through a transmission assembly to drive the first clamping plate 30 and the second clamping plate to move closer or further apart and maintain the position after movement. The entire fixture can be stably placed on the welding worktable, providing a solid foundation for the operation of subsequent components and ensuring that the fixture does not shift or shake in the actual working environment of the welding machine, which helps to accurately maintain the electrode head. The height adjustment mechanism can flexibly adjust the height of the main support plate 5 according to different welding machine models, electrode head installation positions, and actual maintenance operation requirements. This not only adapts to diverse working scenarios and improves the versatility of the fixture, but also ensures that operators can perform electrode head maintenance at the optimal height, which is beneficial to improving the convenience and accuracy of operation. The main support plate 5 provides a stable and reliable support platform for the electrode head body 4, ensuring that the electrode head maintains a stable position during maintenance. This is beneficial for various delicate maintenance operations, such as checking the wear of the electrode head and grinding and repairing the electrode head surface, and also provides the necessary conditions for the clamping mechanism to accurately clamp the electrode head. The first clamping plate 30 and the second clamping plate are slidably connected to the main support plate 5, allowing them to move flexibly relative to each other, achieving tight clamping of electrode heads of different sizes and shapes. This sliding connection structure is simple and stable, ensuring smooth and stable movement of the clamping plates during clamping, thus improving the stability and positioning accuracy of the electrode head during maintenance operations. The lifting drive mechanism precisely controls the relative movement of the first and second clamping plates via a transmission assembly, achieving reliable electrode head clamping and releasing operations. It can precisely adjust the clamping force according to actual operational needs, effectively ensuring the accuracy and stability of operations under different clamping requirements, and can maintain the moved position without continuous manual operation, improving the convenience and efficiency of the operation.

[0027] In a preferred embodiment, two support plates 6 are further included, respectively disposed at both ends of the main support plate 5. The bottom end of the support plate 6 is vertically fixedly connected to the second mounting plate 7, and the top end of the support plate 6 is vertically fixedly connected to one end of the main support plate 5. The two support plates 6 enhance the structural stability and connection strength between the main support plate 5 and the second mounting plate 7. This vertical fixed connection method can effectively distribute the load borne by the main support plate 5, ensuring that the main support plate 5 is stable and reliable during various operations on the electrode head, reducing the possibility of shaking and deformation, thereby improving the overall stability and reliability of the tooling.

[0028] In a preferred embodiment, the lifting drive mechanism includes a first lead screw 8, a first threaded sleeve 16, a lifting plate 15, two limiting rods 11, two limiting plates 10, and a first self-locking drive component. The top end of the first lead screw 8 is rotatably connected to the main bearing plate 5, and the bottom end is rotatably connected to the first mounting plate 1. The two limiting rods 11 are disposed on both sides of the first lead screw 8 and are parallel to the first lead screw 8. The first threaded sleeve 16 is sleeved on the outside of the first lead screw 8 and threadedly connected to the first lead screw 8. The lifting plate 15 is fixedly connected to the first threaded sleeve 16. One end of the limiting plate 10 is provided with a sliding hole, which is sleeved on the outside of the limiting rod 11 for sliding connection with the limiting rod 11. The other end is fixedly connected to the lifting plate 15. The first self-locking drive is installed on the second mounting plate 7, and the output end of the first self-locking drive is connected to the first lead screw 8 to drive the first lead screw 8 to rotate. The lifting plate 15 is connected to the first clamping plate 30 and the second clamping plate through a transmission assembly, so that the first clamping plate 30 and the second clamping plate move closer or further apart during the lifting or lowering of the lifting plate 15. This lifting drive mechanism based on the lead screw and nut transmission with a limiting structure and a self-locking drive can precisely control the lifting movement of the lifting plate 15, thereby achieving precise position adjustment and reliable clamping control of the first clamping plate 30 and the second clamping plate. The setting of the limiting rod 11 and the limiting plate 10 further ensures the straightness and stability of the movement of the lifting plate 15 and prevents it from deviating during the movement; the self-locking drive maintains the adjusted position without the need for continuous external force, avoiding changes in clamping force due to vibration and other factors, and ensuring that the electrode head is stably clamped throughout the maintenance process.

[0029] In a preferred embodiment, the first self-locking drive component includes a worm gear 9 and a worm 3. The worm gear 9 is sleeved and fixed to the bottom of the first lead screw 8, and the worm 3 is meshed with the worm gear 9. Both ends of the worm 3 are rotatably connected to a support plate 6. The self-locking drive component composed of the worm gear 9 and the worm 3 has good self-locking performance, which can prevent the lead screw from reversing due to the reaction force such as the pressure on the electrode head surface after the drive stops. This ensures that the position of the lifting plate 15 is reliably locked, thereby maintaining the stable clamping force of the first clamping plate 30 and the second clamping plate on the electrode head. Moreover, the transmission of the worm gear 9 and the worm 3 is smooth, which can effectively reduce noise and vibration during the transmission process and improve the operational stability of the entire tooling.

[0030] In a preferred embodiment, the first self-locking drive component further includes a first handwheel 2, which is fixedly connected to one end of the worm gear 3 extending out of the support plate 6. The first handwheel 2 provides the operator with a component that is easy to operate manually. By rotating the handwheel, the worm gear 3 and worm wheel 9 can be easily driven, thereby driving the first lead screw 8 to rotate and realizing the control of the clamping plate. This improves the convenience and intuitiveness of tooling operation, allowing the operator to quickly adjust the clamping state of the electrode head according to actual needs. Moreover, the manual operation method is more flexible in some situations, allowing for fine-tuning based on feel and experience.

[0031] In a preferred embodiment, the transmission assembly includes two first connecting rods 14, two second connecting rods, a first slider 28, a second slider, a first connecting plate 27, two second connecting plates 13, a third connecting plate, and two fourth connecting plates. The bottom of the main bearing plate 5 is provided with a first slide rail 32 and a second slide rail. The first slider 28 is slidably fitted into the first slide rail 32, and the second slider is slidably fitted into the second slide rail. The top surface of the first connecting plate 27 is fixedly connected to the bottom surface of the first slide rail 32. The two second connecting plates 13 are respectively fixedly connected to both sides of the first connecting plate 27, and the top surface of the second connecting plate 13 is fixedly connected to the first clamping plate 30. The top surface of the third connecting plate is fixedly connected to the bottom surface of the second slide rail. The system is connected by two fourth connecting plates, each fixedly connected to both sides of the third connecting plate, with the top of each fourth connecting plate fixedly connected to the second clamping plate. One end of each of the two first connecting rods 14 is hinged to both sides of one end of the lifting plate 15, and the other end of each first connecting rod 14 is hinged to a second connecting plate 13. One end of each of the two second connecting rods is hinged to both sides of the other end of the lifting plate 15, and the other end of each second connecting rod is hinged to a fourth connecting plate. This transmission assembly, composed of multiple connecting rods and sliders, efficiently and accurately converts the vertical movement of the lifting plate 15 into the horizontal relative movement of the first clamping plate 30 and the second clamping plate, achieving a stable and reliable clamping function. The hinged and sliding connections between the components ensure smooth motion transmission and can, to a certain extent, adapt to minor deformations or positional changes that may occur in the tooling under different working conditions, guaranteeing the stability and reliability of the entire clamping system and ensuring uniform and stable clamping of the electrode head.

[0032] In a preferred embodiment, the system further includes a first anti-slip pad 31 and a second anti-slip pad. The first anti-slip pad 31 is fixedly connected to the side of the first clamping plate 30 near the second clamping plate, and the second anti-slip pad is fixedly connected to the side of the second clamping plate facing the first clamping plate 30. The first and second anti-slip pads increase the friction between the clamping plate and the electrode head surface, preventing the electrode head from sliding or displacing during clamping, thereby effectively improving the stability of the electrode head during maintenance operations. Especially when rotating or grinding the electrode head, it can better maintain the position of the electrode head, ensuring precise execution of various operations and improving the accuracy and quality of maintenance work.

[0033] In a preferred embodiment, the height adjustment mechanism includes a second self-locking drive and an X-shaped linkage assembly. The upper and lower ends of the first side of the X-shaped linkage assembly are hinged to the first mounting plate 1 and the second mounting plate 7, respectively, and the upper and lower ends of the second side are slidably connected to the first mounting plate 1 and the second mounting plate 7, respectively. The second self-locking drive is mounted on the first mounting plate 1, and the drive end of the second self-locking drive is connected to the X-shaped linkage assembly to drive the second side of the X-shaped linkage assembly to slide and maintain the slid position. This height adjustment mechanism based on the X-shaped linkage assembly and the self-locking drive can achieve smooth and continuous adjustment of the height of the second mounting plate 7. The structure of the X-shaped linkage assembly allows the second mounting plate 7 to rise or fall uniformly during height adjustment, avoiding tilting or jamming. The self-locking drive can lock the adjusted height position, preventing height changes due to external vibrations, changes in the force on the tooling itself, etc., ensuring the stability of the height of the main bearing plate 5 and meeting the precise height requirements of the main bearing plate 5 in different maintenance scenarios.

[0034] In a preferred embodiment, the X-type linkage assembly includes multiple third links 25, multiple fourth links 24, a third slider 22, a fifth connecting plate 21, a fourth slider, and a sixth connecting plate. The middle portions of the third links 25 and the fourth links 24 are rotatably connected by a pivot. A first fixing plate is provided at one end of the bottom surface of the second mounting plate 7, and a third slide rail 23 is provided at the other end. A second fixing plate 26 is provided at one end of the top surface of the first mounting plate 1, and a fourth slide rail is provided at the other end. The top end of the third link 25 is hinged to the first fixing plate, and the bottom end of the fourth link 24 is hinged to the second fixing plate 26. The third slider 22 is slidably fitted into the third slide rail 23. The third link 25 is fixedly connected to the third slider 22. The top end of the fourth link 24 is hinged to the third link 25, and the fourth slider is slidably fitted into the fourth slide rail. The sixth connecting plate is fixedly connected to the fourth slider, and the bottom end of the third link 25 is hinged to the sixth connecting plate. The output end of the second self-locking drive is connected to the fourth slider to drive the fourth slider to slide. (Detailed X-type linkage assembly follows.) The linkage assembly structure design achieves both flexibility and stability in height adjustment. The coordinated operation of multiple linkages and sliders smoothly converts the driving power of the second self-locking drive component into the vertical movement of the second mounting plate 7. Furthermore, the cooperation between the slide rail and slider, and the hinges between the linkages, effectively disperses the stress generated during height adjustment, improving the structure's service life. Simultaneously, this structure allows for precise control of the lifting distance, meeting the height adjustment accuracy requirements for maintaining different welding machine electrode heads.

[0035] In a preferred embodiment, the second self-locking drive component includes a second lead screw 18, a second handwheel 20, a second threaded sleeve 19, a third fixing plate, and a fourth fixing plate 17.

The two ends of the second lead screw 18 are rotatably connected to the third fixing plate and the fourth fixing plate 17, respectively. The second threaded sleeve 19 is sleeved on the outside of the second lead screw 18 and threadedly connected to it. The second threaded sleeve 19 is fixedly connected to the sixth connecting plate. The second handwheel 20 is fixedly connected to one end of the second lead screw 18 extending out of the third fixing plate. This self-locking drive component, consisting of the second lead screw 18, provides a precise and easy-to-operate method for height adjustment. Rotating the second handwheel 20, through the threaded transmission between the second lead screw 18 and the second threaded sleeve 19, precisely controls the movement of the sixth connecting plate, thereby adjusting the height of the second mounting plate 7. The third fixing plate and the fourth fixing plate 17 ensure the stability of the lead screw installation. This structure allows the operator to accurately adjust the height according to actual needs, enhancing the controllability and flexibility of the tooling height adjustment.

[0036] In a preferred embodiment, the system further includes multiple auxiliary support plates 12, each disposed on both sides of the main support plate 5. The two ends of each auxiliary support plate 12 are fixedly connected to the top ends of two support plates 6. The top surface of the auxiliary support plates 12 is used to place the electrode head body 4. The multiple auxiliary support plates 12 increase the load-bearing and support area of ​​the tooling for the electrode head, providing better adaptability for larger or irregularly shaped electrode heads requiring multi-point support. The connection method between the auxiliary support plates 12 and the support plates 6 ensures good stability, can share some of the load on the main support plate 5, improves the overall load-bearing capacity and support stability of the tooling for different types of electrode heads, and provides a more reliable platform for electrode head maintenance.

[0037] In a preferred embodiment, a seventh connecting plate 29 and an eighth connecting plate are also included. The second connecting plate 13 is fixedly connected to the first clamping plate 30 via the seventh connecting plate 29, and the fourth connecting plate is fixedly connected to the second clamping plate via the eighth connecting plate. The seventh connecting plate 29 and the eighth connecting plate enhance the strength and stability of the connection between the clamping plate and the transmission component connecting plate. This allows for better transmission of clamping force, preventing the clamping effect from being affected by loose connections during clamping, and ensuring the reliability of the entire clamping system. Its reasonable structure can improve the stress state of the connection parts to a certain extent, extend the service life of related components, and help ensure that the tooling can achieve precise clamping operation of the electrode head in a long-term and stable manner.
