The welding fixture 10 comprises a carrier 100, a positioning mechanism 300, a rotating mechanism 200 and a first driving assembly 260. The carrier 100 is used to carry a spring disk and an oil storage cylinder 60. The positioning mechanism 300 is connected to the carrier 100, and the positioning mechanism 300 is used to maintain the relative positioning of the spring disk and the oil storage cylinder 60. The rotating mechanism 200 can be pressed against the oil storage cylinder 60, and the rotating mechanism 200 is located on one side of the carrier 100 in the first direction, and the rotating mechanism 200 is used to drive the oil storage cylinder 60 to rotate around the first direction. The first driving assembly 260 is connected to one of the carrier 100 and the rotating mechanism 200, and the first driving assembly 260 is used to drive the carrier 100 and the rotating mechanism 200 to make relative movement in the first direction.

[0045] The first loading device 20 is used to load the spring disk to the carrier 100. The second loading device 30 is used to load the oil storage cylinder 60 to the carrier 100. The welding device 50 is used to weld the spring disk and the oil storage cylinder 60 carried by the carrier 100, and the welding device 50 is corresponding to the rotating mechanism 200. The unloading device 40 is used to unload the welded oil storage cylinder 60. The conveying device 70 is connected to the carrier 100, and the conveying device 70 can drive the carrier 100 to move to correspond to the first loading device 20, the second loading device 30, the welding device 50 and the unloading device 40 in sequence.

[0046] The welding equipment of the embodiment of the present application can load the oil storage cylinder 60 and the spring disk onto the carrier 100, and ensure the relative positioning of the oil storage cylinder 60 and the spring disk during the movement of the carrier 100 through the positioning mechanism 300, and realize the self-rotation of the oil storage cylinder 60 through the rotating mechanism 200, so as to cooperate with the welding device 50 to realize the welding of the oil storage cylinder 60 and the spring disk on the circumferential surface, thereby realizing efficient and high-yield welding of the oil storage cylinder 60 and the spring disk, and avoiding the damage to the body caused by manual welding.

[0047] Specifically, the conveying device 70 can be selected as a conventional belt conveyor or roller conveyor in the art. The first loading device 20, the second loading device 30 and the unloading device 40 can all be selected as conventional feeding manipulators in the art. The first loading device 20, the second loading device 30 and the unloading device 40 can be provided with corresponding conveyor belts for material transportation to facilitate long-distance material transfer. In some embodiments, the first loading device 20 includes a lifting servo, a lateral movement servo and a clamping and positioning cylinder. The first loading device 20 clamps the spring disk provided by the conveyor belt and then rises, and then moves horizontally and descends to be placed on the carrier 100. The second loading device 30 includes a lifting shaft and a translation shaft. The clamping cylinder picks up the oil storage cylinder 60 and then rises and moves to the top of the carrier 100, descends and inserts the oil storage cylinder 60 into the spring disk and positions it to a specified height relative to the spring disk.

[0048] The welding device 50 can be a conventional laser welding device in the art. When the rotating mechanism 200 is rotating, the laser waveform of the welding device 50 and the speed waveform of the rotating mechanism 200 are matched, so that the power and distance of the welding start point and the welding end point can be matched, thereby avoiding the problem that the welding effect at the welding start point and the welding end point is inconsistent with the welding effect of other welding areas due to energy accumulation. During the welding process, the welding device 50 can also cooperate with a visual camera to ensure welding positioning and welding condition monitoring to ensure the welding effect.

[0049] Reference Figure 1 In some embodiments, the conveying device 70 includes a turntable 75, which can rotate around a first direction, and a plurality of carriers 100 are arranged in a circumferential array on the turntable 75. The first loading device 20, the second loading device 30, the welding device 50 and the unloading device 40 are arranged in sequence around the turntable 75. The turntable 75 can drive each carrier 100 to move to correspond to the first loading device 20, the second loading device 30, the welding device 50 and the unloading device 40. By using the turntable 75 and setting the positions of each carrier 100 and the first loading device 20, the second loading device 30, the welding device 50 and the unloading device 40, the loading of the spring disk, the loading of the oil storage cylinder 60, the welding operation and the unloading of the finished product can be carried out simultaneously, so as to speed up the production cycle, improve the production continuity and efficiency, and make the structure of the welding equipment compact and reduce the space occupation.

[0050] Reference Figures 2 to 5In some embodiments, the carrier 100 is provided with a bearing surface 111 on one side in the first direction, the bearing surface 111 is used to bear the spring disk, the carrier 100 is provided with a through hole 120, the through hole 120 extends to the bearing surface 111 along the first direction, and the through hole 120 is used to penetrate the oil storage cylinder 60. The positioning mechanism 300 includes a second driving component 310 and a clamping component 340, and the second driving component 310 is connected to the clamping component 340. After the spring disk is placed on the bearing surface 111 of the carrier 100, the oil storage cylinder 60 is inserted from the through hole 120 of the carrier 100 and positioned relative to the spring disk, the second driving component 310 drives the clamping component 340 to clamp the oil storage cylinder 60, so that the relative positioning of the oil storage cylinder 60 and the spring disk can be maintained.

[0051] The rotating mechanism 200 is located on the opposite side of the bearing surface 111 relative to the carrier 100. The rotating mechanism 200 includes a third driving assembly 210 and a resisting assembly 220. The resisting assembly 220 can be pressed against the oil storage cylinder 60. The third driving assembly 210 is connected to the resisting assembly 220. The third driving assembly 210 is used to drive the resisting assembly 220 to rotate around the first direction. After the carrier 100 moves to the position of the rotating mechanism 200, the first driving assembly 260 drives the carrier 100 and the resisting assembly 220 to approach each other in the first direction to achieve the positioning of the resisting assembly 220 and the oil storage cylinder 60. After the resisting assembly 220 is pressed against the oil storage cylinder 60, the clamping assembly 340 releases the clamping of the oil storage cylinder 60, and the third driving assembly 210 drives the resisting assembly 220 to rotate, thereby driving the oil storage cylinder 60 to rotate, so as to facilitate the welding device 50 to achieve the welding of the circumferential surface.

[0052] Specifically, the movement of the carrier 100 relative to the rotating mechanism 200 in a direction perpendicular to the first direction can be achieved by a conveying device 70 such as a transport trolley, a conveyor belt, or a conveyor turntable.

[0053] In the positioning mechanism 300, the clamping assembly 340 includes a first clamping member 350 and a second clamping member 360 that are arranged opposite to each other, and the relative direction of the first clamping member 350 and the second clamping member 360 is perpendicular to the first direction. The first clamping member 350 and the second clamping member 360 are respectively connected to the carrier 100 in a sliding manner, and the first clamping member 350 and the second clamping member 360 can move closer to or farther from each other. Among them, the second driving assembly 310 can be selected as a driving element having two output ends, and the two output ends can move relative to each other in the first direction, such as a finger cylinder, a pneumatic clamp, so as to achieve the simultaneous approach and distance of the first clamping member 350 and the second clamping member 360 through a single driving element. The second driving assembly 310 can also include a plurality of driving elements that drive linear motion, and the first clamping member 350 and the second clamping member 360 are respectively connected to driving elements to achieve the separate driving of the first clamping member 350 and the second clamping member 360.

[0054] Or, refer to Figure 1 and Figure 3 In other embodiments, the second driving assembly 310 includes a driving module 320 and a plurality of second elastic members 330. The driving module 320 is connected to one side of the first clamping member 350 and the second clamping member 360 in a second direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the relative direction of the first clamping member 350 and the second clamping member 360. The driving module 320 can drive the first clamping member 350 and the second clamping member 360 away from each other. At least one second elastic member 330 is connected to the two sides of the first clamping member 350 and the second clamping member 360 that are away from each other, respectively, and the second elastic member 330 is used to drive the first clamping member 350 and the second clamping member 360 to approach each other. The first clamping member 350 and the second clamping member 360 are brought close to each other by the elastic abutment of the second elastic member 330, which can reduce the requirements on the driving module 320 on the basis of providing the clamping force on the oil storage cylinder 60, so that the driving module 320 only needs to separate the first clamping member 350 and the second clamping member 360 to release the oil storage cylinder 60. Compared with only using the driving module 320 to achieve the clamping and separation actions of the first clamping member 350 and the second clamping member 360, the requirements on the driving module 320 can be effectively reduced, and the driving force that the driving module 320 can output can be reduced. Moreover, since only the separation action needs to be achieved, the driving module 320 can be connected to one side of the first clamping member 350 and the second clamping member 360, and it is not necessary to connect the driving module 320 to both sides of the first clamping member 350 and the second clamping member 360 to ensure stable clamping. For example, the driving module 320 can be configured to include a push rod 321 and two connecting rods 322, wherein the push rod 321 can move in the second direction, the first clamp 350 and the second clamp 360 are respectively rotatably connected with the connecting rod 322, and the two connecting rods 322 are respectively rotatably connected to the pushing rod 321, and the two opposite rotating connection ends of the connecting rod 322 are arranged in sequence in the direction opposite to the first clamp 350 and the second clamp 360, and the push rod is located in the middle of the first clamp 350 and the second clamp 360, and through the movement of the pushing rod 321 in the second direction, the first clamp 350 and the second clamp 360 can be spread apart by the two connecting rods 322, so that the first clamp 350 and the second clamp 360 are moved away from each other. Among them, the pushing rod 321 can be a driving element that can realize the pushing action by itself, such as a telescopic rod, or a sliding rod that is pushed by an external driving element.

[0055] Reference Figure 1 , Figure 4 and Figure 5In some embodiments, the abutting assembly 220 includes a rotating seat 230 and a plurality of abutting members 240. The rotating seat 230 is connected to the third driving assembly 210. The abutting members 240 are slidably connected to the rotating seat 230. At least two abutting members 240 are arranged opposite to each other in a direction perpendicular to the first direction. The relative abutting members 240 can approach or move away from each other. The rotating seat 230 provides a connection basis for the abutting members 240 on the basis of realizing the self-rotation action. Through the relative movement of the relative abutting members 240, the oil storage cylinder 60 can be tightened and loosened, so as to drive the oil storage cylinder 60 to rotate or loosen the oil storage cylinder 60.

[0056] There can be multiple groups of opposing abutting members 240, for example, two groups of opposing abutting members 240 are shown in the figure, so as to realize multi-point abutment on the oil storage cylinder 60 and improve the abutment stability. Each abutting member 240 can be arranged in a circular array with the rotation center as the center, so as to provide a uniform abutment force. The relative movement of the opposing abutting members 240 can be achieved by a driving element that can drive the abutting members 240 to move in a straight line, such as a driving element such as a finger cylinder, a pneumatic clamp or a one-way driving rod. Alternatively, in other embodiments, referring to Figure 1 , Figure 5 and Figure 6 The supporting assembly 220 also includes a first elastic member 250, which extends in a direction perpendicular to the first direction. One end of the first elastic member 250 is connected to the rotating seat 230, and the other end of the first elastic member 250 is connected to the supporting member 240. The first elastic member 250 is used to drive the relative supporting members 240 to move closer to or away from each other, so that the relative supporting members 240 can be pressed against the outer side of the oil storage cylinder 60 or spread on the inner side of the oil storage cylinder 60, so that the oil storage cylinder 60 can rotate together with the rotating seat 230.

[0057] The abutting assembly 220 is provided with an avoidance structure to solve the interference between the abutting member 240 and the oil storage cylinder 60. For example, when the abutting member 240 is able to move along the first direction to the outside of the oil storage cylinder 60, the oil storage cylinder 60 is clamped by the elastic force of the first elastic member 250. Alternatively, when the abutting member 240 is able to move along the first direction to the inside of the oil storage cylinder 60, the oil storage cylinder 60 is supported by the elastic force of the first elastic member 250. The avoidance structure can be selected as a driving element that can drive the abutting member 240 to move in a straight line, such as a driving element such as a one-way driving rod. Alternatively, refer to Figure 1 and Figure 5 In some embodiments, the abutting member 240 is provided with a guide surface 241, which is inclined to the first direction. The guide surface 241 abuts against the oil storage cylinder 60 through the seat avoidance structure, so that the abutting member 240 can move toward the direction close to the first elastic member 250. Figure 1 , Figure 5 and Figure 6 For example, the first elastic member 250 is disposed between the opposite abutting members 240, and applies elastic forces in directions away from each other to the opposite abutting members 240. When the abutting assembly 220 and the oil storage barrel 60 are relatively close to each other in the first direction, since the abutting surface is inclined in the direction facing the opposite abutting members 240, the abutting surface can abut against the inner surface of the oil storage barrel 60, and the abutting member 240 overcomes the elastic force of the first elastic member 250 under the guidance of the abutting surface until it has a sufficient abutting area with the inner surface of the oil storage barrel 60. At this time, the abutting member 240 is pressed against the oil storage barrel 60 under the elastic force of the first elastic member 250, and multiple oil storage barrels 60 are pressed against the inner surface of the oil storage barrel 60 in a stretched form, so that the oil storage barrel 60 can rotate with the rotating seat 230.

[0058] It can be understood that the first elastic member 250 can be arranged in a variety of forms, such as by connecting a single first elastic member 250 to the opposite side of two opposite supporting members 240 to provide elastic force, for example, by connecting multiple first elastic members 250 to the opposite side of two opposite supporting members 240 to provide elastic force, for example, by connecting multiple first elastic members 250 to the opposite side of two opposite supporting members 240 to provide elastic force. The first elastic member 250 can provide both pulling force and pushing force.

[0059] In some embodiments, the abutting assembly 220 further includes a telescopic portion 225, which is slidably connected to the rotating seat 230, and can move relative to the rotating seat 230 in a first direction, and the telescopic portion 225 can abut against the oil storage cylinder 60, one end of the first elastic member 250 is connected to the telescopic portion 225, and the other end of the first elastic member 250 is connected to the abutting member 240. The telescopic portion 225 can provide a connection basis for the first elastic member 250, and after welding is completed, the telescopic portion 225 can move in the first direction to lift the oil storage cylinder 60 to facilitate subsequent unloading.

[0060] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the rotating seat 230 is provided with a limiting groove 231, and the abutting member 240 is accommodated in the limiting groove 231. The limiting groove 231 provides a limit for the abutting member 240, which can facilitate the installation of the abutting member 240 and improve the structural stability.

[0065] The conveying device 70 drives the carrier 100 to move to the spring disk loading position 71, and the first loading device 20 loads the spring disk into the accommodating groove 110. Subsequently, the conveying device 70 drives the carrier 100 to move to the oil storage cylinder loading position 72, and the second loading device 30 inserts the oil storage cylinder 60 into the penetration hole 120. After the oil storage cylinder 60 and the spring disk are relatively positioned, the second driving component 310 drives the clamping component 340 to clamp the oil storage cylinder 60 to maintain the positioning of the oil storage cylinder 60 and the spring disk. Subsequently, the conveying device 70 drives the carrier 100 to move to the welding position 73, and the welding device 50 spot welds the oil storage cylinder 60 and the spring disk so that the spring disk can move with the oil storage cylinder 60. Subsequently, the first driving component 260 drives the abutting component 220 to approach the oil storage cylinder 60 along the first direction, so that the abutting member 240 abuts against the oil storage cylinder 60. Subsequently, the clamping assembly 340 is released, the third driving assembly 210 drives the rotating seat 230 to rotate, and the welding device 50 simultaneously welds the circumferential surface of the spring disk and the oil storage cylinder 60. After welding is completed, the clamping assembly 340 re-clamps the oil storage cylinder 60, the abutting assembly 220 is reset, and the welding device 50 is reset. Subsequently, the conveying device 70 drives the carrier 100 to move to the unloading position 74, and the unloading device 40 unloads the welded finished product.

[0066] Reference Figures 1 to 5 According to the welding method of the embodiment of the present invention, based on the welding equipment of any of the above embodiments, the welding method comprises the following steps:

[0067] The carrier 100 sequentially receives the spring disk and the oil reservoir 60 and positions them relative to each other;

[0068] The positioning mechanism 300 locks the oil storage cylinder 60 on the carrier 100;

[0069] When the carrier 100 moves to a state corresponding to the rotating mechanism 200, the welding device 50 spot welds the spring disk and the oil storage cylinder 60;

[0070] The rotating mechanism 200 is pressed against the oil storage cylinder 60;

[0071] The positioning mechanism 300 releases the oil storage cylinder 60;

[0072] The rotating mechanism 200 drives the oil storage cylinder 60 to rotate, and the welding device 50 welds the spring disk and the oil storage cylinder 60 synchronously.

[0073] The welding method of the present application can realize the loading, positioning and welding of the spring disk and the oil storage cylinder 60, and by spot welding before the positioning mechanism 300 releases the oil storage cylinder 60, it can ensure the relative positioning of the oil storage cylinder 60 and the spring disk, and when the oil storage cylinder 60 starts to rotate, the spring disk rotates with the oil storage cylinder 60, thereby reducing the welding difficulty of the welding device 50 and ensuring the welding yield.
