Usually, a manual welding method is used to weld a full circle. This method has extremely high requirements for the welding skills of operators, and unstable positioning of the material tank and the cover plate will lead to insufficient weld strength, leakage problems, resulting in a decrease in cooling effect or liquid overflow, affecting the normal operation of the ice cream machine; in addition, the welding positioning dimensions of the material tank and the cover plate are fixed and cannot adapt to different sizes of material tanks and cover plates, which has certain limitations. Summary of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of the limitations of the existing material tank welding system of ice cream machines, the purpose of the utility model is to provide a laser welding positioning system for the material tank of an ice cream machine, which solves the problem that the positioning dimensions in the welding process of the material tank and the cover plate of the existing ice cream machine are fixed and cannot adapt to different sizes of material tanks and cover plates, and has certain limitations. At the same time, it solves the problem that the unstable positioning of the material tank and the cover plate leads to insufficient weld strength, temperature deformation, and leakage risk.

[0005] (2) Technical Solutions

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a laser welding system for the material tank of an ice cream machine, including a welding frame, a welding die covered on the top of the welding frame, pressing plates symmetrically arranged at the left and right ends of the top of the welding die, and an automatic laser welding gun movably arranged on the top of the welding die. The welding frame is a frame structure, including four columns arranged at four corner points, and four cross beams sequentially connecting the four columns. The cross beams are telescopic rods, and a number of positioning holes are arranged on both the upper surface and the lower surface. The positions of the number of positioning holes on the upper surface correspond to those on the lower surface one by one. In this system, through the mutual cooperation and coordination among the telescopic cross beams of the welding frame, the welding die, and the automatic laser welding gun, it can adapt to different sizes of material tanks and cover plates, accurately position them, and ensure the stability between the material tank and the cover plate, thereby avoiding problems such as insufficient weld strength, temperature deformation, and leakage risk caused by unstable positioning.

[0007] Specifically, the welding frame with a frame structure can provide stable support. The connection between the vertical columns and the crossbeam provides higher strength and stability for the welding frame, ensuring that the structure is not easily deformed or damaged during the welding process, which is conducive to maintaining the accuracy and consistency of welding.

[0008] Specifically, the design of the telescopic rod enables the crossbeam to be telescoped as needed to adapt to ice cream machine troughs and covers of different sizes, allowing for the processing of products of different specifications, making the system more adaptable to different welding requirements, with a certain degree of flexibility and adjustability, and improving the adaptability of the system.

[0009] Specifically, multiple positioning holes are provided on the crossbeam for connecting the welding mold to the welding frame, thereby positioning the trough and the cover, providing precise positioning for the trough and the cover, enabling the welding frame to adapt to different welding sizes while ensuring the precise positioning of welding, improving the accuracy and stability of welding positioning, and enhancing the precision and consistency of welding.

[0010] Specifically, the automatic laser welding gun can perform welding according to the programmed route, reducing the intervention of manual operation and increasing the automation level of the system. Preferably, the welding mold is a rectangular steel plate adapted to the size of the top of the welding frame, with a trough relief hole in the middle. Integrating the welding mold with the welding frame ensures the matching between the welding mold and the welding frame, effectively improving the stability and precision of welding.

[0011] Furthermore, the trough relief hole in the welding mold is used to accommodate the position of the trough and ensure the accurate positioning of the trough and the welding mold, capable of maintaining the precise positioning of the trough during the welding process, improving the precision and accuracy of welding.

[0012] Preferably, heating strips are fixed along the circumference of the trough relief hole at the bottom of the welding mold. Setting the heating strips can increase the temperature at the bottom of the welding mold, better control the welding temperature. At the same time, the heating strips can provide additional heat to accelerate the welding process and improve production efficiency.

[0013] Furthermore, controlling the temperature at the bottom of the welding mold can reduce the temperature difference generated during the welding process, thereby reducing the possibility of temperature deformation during welding, and can better manage the heat input during the welding process, ensuring the uniformity and tightness of the weld seam, avoiding problems such as gaps and leaks, and improving the precision and efficiency of welding.

[0014] Preferably, four pressure plate mounting holes are respectively provided at the four corner points of the welding mold, which can accurately install the pressure plates to ensure the fixed connection between the welding mold and the cover. The pressure plate mounting holes are respectively arranged at the four corner points to achieve uniform and stable fixation of the cover, preventing displacement or shaking during the welding process, and improving the stability and accuracy of welding.

[0015] Preferably, two positioning screws are symmetrically arranged on the left and right sides of the welding die respectively. The positioning screws are arranged inside the pressing plate mounting holes. After passing through the positioning holes at the corresponding positions on the welding frame, the positioning screws are fixedly connected to the welding frame. The positioning screws cooperate with the telescopic cross bar to achieve precise positioning of the welding die, so as to achieve precise positioning of the material trough and the upper cover. At the same time, after the positioning screws pass through the positioning holes, the welding die is precisely fixed to the welding frame, maintaining a firm connection between the welding die and the welding frame, preventing displacement and shaking during the welding process, providing stable support while achieving precise positioning, and improving the welding accuracy and consistency.

[0016] Preferably, the pressing plate is a long strip-shaped pressing plate, and both ends are bent downward and fixed in the pressing plate mounting holes. The pressing plate is symmetrically arranged left and right along the center of the welding die. The long strip-shaped pressing plate applies pressure evenly along the entire length of the die, providing more uniform and stable support, while providing stable positioning, preventing deviation, and improving the welding accuracy and consistency.

[0017] In addition, the pressing plates symmetrically arranged at the left and right ends of the welding die can help maintain the balance during the welding process. This can reduce the deformation during the welding process and ensure the welding quality.

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] Example 1: Please refer to Figures 1 to 5 The first specific embodiment of the utility model provides a trough laser welding positioning system for an ice cream machine, comprising a welding frame 1, a welding mold 2 covered on the top of the welding frame 1, a pressing plate 3 symmetrically arranged at the left and right ends of the top of the welding mold 2, and an automatic laser welding gun 4 movably arranged on the top of the welding mold 2. The welding frame 1 is a frame structure, comprising four columns 11 arranged at four corner points, and four cross beams 12 sequentially connected to the four columns 11. The cross beam 12 is a telescopic rod, and a plurality of positioning holes 123 are arranged on the upper surface and the lower surface thereof. The positions of the plurality of positioning holes 123 on the upper surface correspond to the positions on the lower surface one by one, so that the welding The mold 2 is fixed on the top of the welding frame, and the retractable beam 12 can adapt to the sizes of different welding molds 2, that is, it can adapt to the sizes of different material troughs and cover plates. Specifically, when the size of the welding mold 2 is slightly larger, the beam 12 can be lengthened to expand the size of the welding frame 1. Each beam 12 can be retracted, that is, the welding frame 1 can be retracted and extended simultaneously in the horizontal and vertical directions. When fixedly connected with the welding mold 2 through the positioning holes, the welding mold 2 can be accurately positioned and fixed, thereby realizing accurate positioning of the material trough and the cover plate, thereby avoiding the situation where unstable positioning leads to insufficient weld strength, temperature deformation and leakage.

[0030] The welding die 2 is a rectangular steel plate that adapts to the size of the top of the welding frame 1. A material groove relief hole 21 is provided in the middle. The material groove relief hole 21 is used to place the material groove, that is, it can accurately position the material groove. The cover plate is placed on the upper surface of the material groove. The size of the material groove relief hole 21 fits the size of the material groove. That is to say, the inner diameter of the material groove relief hole 21 is equal to the outer diameter of the bottom of the material groove. This can make the material groove fit tightly with the material groove relief hole 21, ensuring the stable and accurate positioning of the material groove and the welding die 2, and avoiding displacement or shaking during the welding process, which affects the welding effect. At the bottom of the welding die 2, a heating strip 22 is fixed along the circumference of the material groove relief hole 21. During the welding process, the heating strip will be heated to heat the bottom of the welding die 2. The continuous heating of the heating strip can provide a certain temperature, thereby reducing the temperature difference and deformation generated during the welding process, reducing the risk of welding deformation. Heating can also effectively control the welding temperature, ensure the uniformity and tightness of the weld seam, avoid the generation of gaps and leakage problems, improve the welding accuracy and efficiency, and at the same time help the material groove and the cover plate reach the welding temperature faster, shorten the entire welding cycle, and improve production efficiency.

[0031] Four pressing plate mounting holes 23 are respectively provided at the four corner points of the welding die 2 for installing pressing plates to effectively fix the cover plate, avoid displacement and shaking, and can help the cover plate and the material groove to be accurately positioned.

[0032] Two positioning screws 24 are symmetrically arranged on the left and right sides of the welding die 2 respectively. The positioning screws 24 are arranged inside the pressing plate mounting holes 23. The positioning screws 24 pass through the positioning holes 123 at the corresponding positions on the welding frame 1 and are fixedly connected to the welding frame 1. After adjusting the size of the welding frame 1, the welding die 2 is placed on the top of the welding frame 1. At this time, the positioning screws 24 on the welding die 2 look for the positioning holes 123 at the corresponding positions on the cross beam 12. After the positioning screws 24 pass through the positioning holes 123, they are fixed by nuts, and the welding die 2 is fixed on the welding frame 1. This can achieve the accurate fixation of the welding die 2 on the welding frame 1, thereby realizing the accurate positioning of the material groove and the cover plate. Subsequently, the four sides where the material groove contacts the upper cover plate are welded by the automatic laser welding gun 4 according to the route set by the program. Accurate positioning and stable fixation can ensure the accurate progress of welding, guarantee the strength of the weld seam, reduce the risk of leakage, and improve the welding accuracy and accuracy.

[0033] The pressing plate 3 is a long strip-shaped pressing plate. The two ends are bent downward and fixed in the pressing plate mounting holes 23 respectively. The pressing plate 3 is symmetrically arranged left and right along the center of the welding die 2. The pressing plates respectively fix the left and right sides of the cover plate, and at the same time longitudinally fix the cover plate through the downward-bent two ends to prevent it from shifting or shaking, improve the accuracy and stability of the positioning of the material groove and the cover plate, and improve the accuracy and consistency of welding.

[0034] Working principle: When in use, first extend or shorten the crossbeam 12 in the horizontal and vertical directions simultaneously according to the size of the welding mold 2, adjust the size of the welding frame 1 to adapt to the size of the welding mold 2, and then install the side of the welding mold 2 fixedly mounted with the positioning screw 24 downwardly on the top of the welding frame 1, and at the same time, the positioning screw 24 corresponds to the positioning hole 123 at the corresponding position on the crossbeam 12, and is fixed by a nut after passing through the positioning hole 123, and then the material trough of the ice cream machine is placed in the material trough clearance hole 21 on the welding mold 2, and the material trough is fixed in the material trough clearance hole 21, and then the cover plate is passed from left to right through the pressure plates 3 on the left and right sides of the welding mold 2 and covered on the material trough, and the pressure plates 3 on both sides will fix the cover plate, and then use the automatic laser welding gun 4 to weld the four sides of the material trough in contact with the upper cover plate according to the route set by the program.
