DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-10 , the present invention provides a technical solution: Embodiment 1

[0022] The welding fixture for electric new energy automobile parts of the present invention comprises an adjustable support frame 1. The support frame is made of high-strength material, ensuring that it can still maintain sufficient stability and durability when bearing heavy loads.

[0023] The design of the support frame fully considers the diversity of new energy vehicle accessories, especially the differences in size and shape. Its unique structural design allows operators to flexibly adjust the position and length of the support frame according to the actual size of the accessories to be welded through simple operations, thereby achieving accurate adaptation to different accessories.

[0024] Two symmetrical clamping modules 2 are provided on the support frame. These two clamping modules 2 are key components for the clamping operation and are responsible for fixing the accessories to be welded. Each clamping module 2 is equipped with a strong clamping force and a stable structure to ensure that the accessories will not loosen or move during the welding process.

[0025] The hydraulic drive device 6 is the power source of the clamp, and is used to provide power to control the opening and closing of the clamping module 2. The device drives the clamping and releasing of the clamping module 2 through the extension and contraction of the hydraulic cylinder. The hydraulic drive device 6 has the advantages of fast response speed, large driving force, good stability, etc., and can quickly and stably complete the clamping action, thereby improving the welding efficiency.

[0026] The electronic control system 7 is the intelligent core of the clamp, which includes two main parts: the sensor 8 and the controller 9. The sensor 8 is used to monitor the status of the clamp and accessories in real time, such as position, angle, pressure and other parameters. The controller 9 accurately controls the action of the clamp according to the feedback signal of the sensor 8 to ensure coordinated work with the welding equipment.

[0027] The electronic control system 7 also has fault diagnosis and alarm functions. Once a fault is found in the fixture or welding equipment, the system will immediately send out an alarm signal to remind the operator to deal with it in time. In addition, the system also supports remote monitoring and operation, which is convenient for operators to remotely control and manage the fixture.

[0028] The adjustment support frame mainly consists of a first sleeve 10 and a second sleeve 11, which are made of high-strength materials to ensure sufficient stability and durability when bearing heavy loads. The first sleeve 10 is sleeved in the second sleeve 11, and the two achieve axial movement through precise sliding fit.

[0029] In order to achieve precise adjustment of the length of the support frame, a length adjustment hydraulic cylinder 12 is provided between the first sleeve 10 and the second sleeve 11. The hydraulic cylinder pushes the first sleeve 10 to move axially relative to the second sleeve 11 through telescopic action, thereby achieving stepless adjustment of the length of the support frame. This design allows the operator to easily adjust the length of the support frame according to actual needs to adapt to accessories of different sizes.

[0030] By extending and retracting the length adjustment hydraulic cylinder 12, the support frame can be infinitely adjusted in the axial direction to adapt to accessories of different sizes, thereby improving the adaptability and stability during welding. The operator can adjust the length of the support frame through simple operations without the need for complex tools or equipment, thus reducing the difficulty of operation and labor intensity. Embodiment 2

[0031] Based on the first embodiment, this embodiment describes the clamping module 2 of the first embodiment and proposes a more efficient and accurate clamping solution. Through the clamping module 2 of this embodiment, the operator can achieve fast and stable clamping of automobile parts of different shapes and sizes, thereby improving the efficiency and quality of welding operations.

[0032] The clamping module 2 mainly includes a fixed frame 13 and a plurality of clamping rods 14. The fixed frame 13 serves as the basic frame of the clamping module 2, and a plurality of clamping rods 14 are arranged inside the fixed frame 13. The clamping rod 14 consists of a fixed rod 1401 and a sliding rod 1402. One end of the fixed rod 1401 is fixed to the bottom wall of the fixed frame 13, and the other end is provided with a limit plate 1403 to prevent the sliding rod 1402 from sliding out. A plurality of sliding rods 1402 are arranged on the fixed rod 1401 along its axial sliding direction, and a limit sleeve 1404 is fixedly arranged at one end of the sliding rod 1402 to ensure the stability of the sliding rod 1402 during the sliding process. At the same time, a spring 1405 is sleeved on the outer side of the fixed rod 1401 to provide a reset force during the clamping process.

[0033] In order to achieve adaptive clamping of automobile parts of different shapes, the clamping module 2 is provided with a square groove 15 on the side wall of the fixed frame 13. A pressing plate 16 is movably arranged in the square groove 15, and hydraulic oil is injected into the square groove 15 by the hydraulic drive device 6 to drive the movement of the pressing plate 16. When the pressing plate 16 is squeezed by the hydraulic oil, it will be arranged along the axial direction of the vertical clamping rod 14 and squeeze the sliding rod 1402, thereby limiting the sliding of the sliding rod 1402 on the fixed rod 1401. In this way, the clamping module 2 can be adaptively adjusted according to the shape of the automobile parts to form a fixture shape that matches the contour of the parts.

[0034] In actual use, the operator first activates the length adjustment hydraulic cylinder 12 according to the size of the automobile part to be welded, and adjusts the size of the adjustable support frame 1 to adapt to the size of the part. Then, the support rod 20 at the bottom of the clamping module 2 is rotated so that the support rod 20 can stably support the automobile part to be welded. According to the size of the part, the operator can pull the second telescopic rod 2002 out of the first telescopic rod 2001 to optimize the support effect.

[0035] After completing the support adjustment, the operator places the automobile part to be welded on the support rod 20. Then, the clamping adjustment hydraulic cylinder 19 is started. Driven by the hydraulic cylinder, the clamping module 2 gradually approaches the automobile part and clamps it. During the clamping process, part of the clamping rod 14 in the clamping module 2 is squeezed, and the sliding rod 1402 slides on the fixed rod 1401 and squeezes the spring 1405; while the clamping rod 14 that is not squeezed remains unchanged. In this way, the clamping module 2 can be adaptively adjusted according to the shape of the automobile part to form a fixture shape that matches the contour of the part.

[0036] When the clamping module 2 completely matches the outer shape of the automobile part, the operator starts the hydraulic drive device 6 and injects hydraulic oil into the square groove 15. The hydraulic oil squeezes the pressing plate 16, which is arranged along the axial direction of the vertical clamping rod 14 and squeezes the sliding rod 1402, so that the sliding rod 1402 can no longer slide. At this time, the shape of the clamp is fixed, and the clamping module 2 can stably clamp the automobile part, providing strong support for subsequent welding operations.

[0037] When it is necessary to replace auto parts, the operator only needs to start the hydraulic drive device 6 to unload the hydraulic oil. As the hydraulic oil decreases, the squeezing force of the pressure plate 16 on the clamping rod 14 gradually disappears, and the sliding rod 1402 is reset to the original state under the squeezing of the spring 1405. At this time, the clamping module 2 can easily release the auto parts, making it convenient for the operator to replace or adjust.

[0038] Embodiment three: In the welding process of electric new energy vehicle accessories, complex-shaped auto parts often need to be welded at multiple angles. In order to meet this demand, the embodiment of this patent describes the angle adjustment mechanism 3 on the original basis. Through the angle adjustment mechanism 3 of this embodiment, the operator can achieve fast and accurate angle adjustment of auto parts, thereby greatly improving the flexibility and efficiency of welding operations.

[0039] The angle adjustment mechanism 3 of this embodiment mainly includes a reducer 4 fixedly arranged on the adjustable support frame 1. As the core component of angle adjustment, the reducer 4 has the characteristics of high precision, high torque, low speed, etc. A drive motor 5 is fixedly arranged on the reducer 4 to provide power for the reducer 4. The drive motor 5 controls the rotation of the reducer 4 to realize the rotation of the clamping module 2, thereby driving the automobile parts to adjust at multiple angles.

[0040] In order to realize the program linkage between the welding robot and the angle adjustment mechanism 3, a corresponding control program is set in the system. After the automobile parts are stably clamped by the clamping module 2, the welding robot and the angle adjustment mechanism 3 communicate and cooperate through the program. According to the welding requirements, the welding robot can send instructions to the angle adjustment mechanism 3 in real time to control it to make precise angle adjustments. At the same time, the angle adjustment mechanism 3 will also feed back the current rotation angle to the welding robot in real time to ensure the accuracy and stability of the welding operation.

[0041] In this embodiment, the clamping module 2 is rotatably arranged on the adjustable bracket via the shaft seat 17. The shaft seat 17 serves as the rotation support point of the clamping module 2, and its structure is firm and the rotation is flexible. In order to ensure the stability and smoothness of the clamping module 2 during the rotation process, a bearing 18 is arranged between the shaft seat 17 and the adjustable bracket. The bearing 18 can effectively reduce the rotation friction, reduce the energy loss, and improve the rotation accuracy and life.

[0042] In actual use, the operator first places the automobile part to be welded on the adjustable support frame 1 and starts the clamping module 2 for clamping. After the clamping is completed, the operator can start the drive motor 5 through the control program to drive the reducer 4 to drive the clamping module 2 to rotate. According to the welding requirements, the operator can adjust the rotation angle of the clamping module 2 in real time to ensure that the automobile part is in the best welding position.

[0043] When the automobile parts are in a suitable welding position, the operator can start the welding robot to perform welding operations. During the welding process, the welding robot and the angle adjustment mechanism 3 are linked by a program to adjust the welding angle and position in real time to ensure welding quality and efficiency.

[0044] Embodiment 4: In the welding process of electric new energy vehicle accessories, the stability and adjustability of the clamping module 2 are crucial to the welding quality and efficiency. In order to meet this demand, the embodiment of the present patent further optimizes and improves the clamping module 2 and its adjustment mechanism on the original basis. By introducing the clamping adjustment hydraulic cylinder 19, the support rod 20 and the guide mechanism, the clamp of this embodiment can achieve more stable clamping and more flexible adjustment of automobile parts, thereby further improving the accuracy and efficiency of the welding operation.

[0045] In this embodiment, a clamping adjustment hydraulic cylinder 19 is provided on another clamping module 2. The clamping adjustment hydraulic cylinder 19 is rotatably provided on an adjustable bracket, and the clamping module 2 is provided at the movable end of the clamping adjustment hydraulic cylinder 19. By controlling the extension and retraction of the clamping adjustment hydraulic cylinder 19, the operator can achieve precise adjustment of the clamping module 2, thereby ensuring that the automobile part is stably and accurately clamped in the fixture.

[0046] In order to support the automobile parts before the clamping module 2 works, the present embodiment rotatably sets a support rod 20 at the bottom of the clamping module 2. The support rod 20 is composed of a first telescopic rod 2001 and a second telescopic rod 2002, and the second telescopic rod 2002 is slidably set in the first telescopic rod 2001. This design allows the length of the support rod 20 to be adjusted as needed to adapt to automobile parts of different sizes and shapes. Before the clamping module 2 clamps the automobile parts, the support rod 20 can provide a supporting force to ensure the stability of the clamping.

[0047] In order to ensure the stability and accuracy of the clamping and adjusting hydraulic cylinder 19 during the extension and retraction process, the present embodiment has a guide plate 21 fixedly arranged on the fixed end of the clamping and adjusting hydraulic cylinder 19. On the guide plate 21, we have fixedly arranged a guide sleeve 22. The guide sleeve 22 is made of wear-resistant, high-strength material and has good guiding performance.

[0048] Matching the guide sleeve 22 is a guide post 23 fixedly arranged on the fixed frame 13. The guide post 23 is inserted into the guide sleeve 22 to form a sliding fit. When the clamping and adjusting hydraulic cylinder 19 is extended and retracted, the guide post 23 slides in the guide sleeve 22, thereby ensuring that the movement trajectory of the clamping and adjusting hydraulic cylinder 19 is accurate and stable. The design of this guide mechanism not only improves the overall stability of the clamp, but also helps to extend the service life of the clamping and adjusting hydraulic cylinder 19.

[0049] The embodiment of the present invention improves the clamping module 2 and its adjustment mechanism by introducing optimization measures such as the clamping adjustment hydraulic cylinder 19, the support rod 20 and the guide mechanism. These optimization measures enable the clamp to achieve more stable clamping and more flexible adjustment of automotive parts, thereby improving the accuracy and efficiency of welding operations. In addition, the design of the guide mechanism also helps to improve the overall stability of the clamp and extend its service life.

[0050] In the welding process of electric new energy vehicle accessories, the mobility and stability of the clamp are of great significance to improving welding efficiency and reducing operation difficulty. In order to meet this demand, the embodiment of this patent enhances the mobility and stability of the adjustable bracket on the original basis. By introducing designs such as universal wheels 24, height-adjustable foot pads 25, and reinforced ribs 26, the clamp of this embodiment can achieve convenient movement and adjustment while ensuring stability, thereby further improving the flexibility and efficiency of welding operations.

[0051] In this embodiment, a universal wheel 24 is fixedly provided at the bottom of the adjustable bracket. The design of the universal wheel 24 allows the clamp to slide easily on the ground, making it easy for the operator to move the clamp to the vicinity of the automobile parts to be welded. At the same time, the universal wheel 24 also has good steering performance, so that the clamp can flexibly adjust its direction during movement to adapt to different working environments. At the same time, during the extension and retraction of the adjustable bracket, the universal wheel 24 can also reduce the friction between the bracket and the ground; In this embodiment, a height-adjustable foot pad 25 is fixedly arranged at the bottom of the adjustable bracket. The foot pad 25 is made of high-strength material and has good load-bearing capacity and stability. By adjusting the height of the foot pad 25, the operator can conveniently adjust the overall height of the clamp to keep a proper distance from the automobile parts, which is convenient for welding operations.

[0052] In order to further enhance the strength and stability of the adjustable bracket, in this embodiment, a reinforcing rib 26 is fixedly provided on both the first sleeve 10 and the second sleeve 11. The reinforcing rib 26 is made of the same or similar material as the sleeve and is fixed to the sleeve by welding or bolting. The design of the reinforcing rib 26 can effectively increase the bending and torsion resistance of the sleeve, and improve the load-bearing capacity and stability of the entire clamp.

[0053] The embodiment of the present invention enhances the mobility and stability of the adjustable bracket by introducing universal wheels 24, height-adjustable foot pads 25, and reinforcing ribs 26. These optimization measures enable the fixture to be easily moved and adjusted while ensuring stability, thereby further improving the flexibility and efficiency of welding operations. In addition, the design of the reinforcing ribs 26 also helps to improve the overall strength and load-bearing capacity of the fixture, enabling it to adapt to more complex and harsh working environments; The fixing rod is installed on the fixing frame in a way that is easy to disassemble. Specifically, a threaded hole is opened at one end of the fixing rod. At the same time, a number of stepped holes are evenly distributed on the fixing frame. During installation, the end of the fixing rod with the threaded hole is inserted into the stepped hole on the fixing frame. The design of the stepped hole can provide stable support and positioning for the fixing rod, ensuring that the fixing rod will not shake or shift during use.

[0054] The other end of the fixing rod is fixed by bolts. The bolts pass through the pre-set holes on the fixing frame and match the threaded holes on the other end of the fixing rod to firmly fix the fixing rod on the fixing frame. This connection method is simple and reliable, and is easy to disassemble and repair when necessary.

[0055] When the combination of the fixing rod and the fixing frame is needed, the fixing rod is inserted into the step hole of the fixing frame, and then the bolt is screwed into the threaded hole of the fixing rod from the other side of the fixing frame, and the fixing rod is firmly fixed to the fixing frame by the tightening force of the bolt. In this way, the fixing rod can play its supporting, fixing or other special role on the fixing frame.

[0056] When disassembly is required, the fixing rod can be removed from the fixing frame by simply loosening the bolts, which is convenient and quick.

[0057] Working principle: When the clamping modules 2 are driven by the clamping adjustment hydraulic cylinder 19 to approach each other during use, part of the clamping rod 14 in the clamping module 2 will be squeezed by the automobile parts. The sliding rod 1402 of this part of the clamping rod 14 will slide on the fixed rod 1401 and compress the spring 1405. The clamping rod 14 that is not squeezed remains stationary. In this way, the clamping module 2 can adaptively adjust the position of the clamping rod 14 according to the contour shape of the automobile parts to form a clamp shape that matches the outer shape of the parts.

[0058] In order to fix the formed fixture shape, the hydraulic drive device 6 injects hydraulic oil into the square groove 15 on the side wall of the fixing frame 13. The pressure of the hydraulic oil pushes the pressing plate 16 in the square groove 15, and the pressing plate 16 presses the sliding rod 1402 in a direction perpendicular to the axial direction of the clamping rod 14, preventing the sliding rod 1402 from sliding further on the fixing rod 1401. In this way, the clamping module 2 can maintain the fixture shape formed by it, ensuring that the automobile parts are stably clamped during the welding process.

[0059] When the auto part needs to be replaced, the hydraulic drive device 6 will unload the hydraulic oil, and the pressure plate 16 will lose the hydraulic oil and no longer press the sliding rod 1402. At this time, the previously compressed spring 1405 will release its stored potential energy and push the sliding rod 1402 to return to the initial position. The clamping module 2 is thus restored to its original state, ready to clamp the next auto part.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
