[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a welding fixture for refrigeration equipment, including an assembly table 1, an annular guide groove 101 is provided on the top surface of the assembly table 1, a guide ring assembly 301 is installed inside the guide groove 101, the guide ring assembly 301 is annular, and an annular guide seat mechanism 3 is fixedly connected to the top surface of the guide ring assembly 301.

[0026] A guide tooth assembly 3011 is fixedly connected in a ring array on the outer peripheral surface of the guide seat mechanism 3. A longitudinally arranged guide frame assembly 3012 is fixedly connected on the top surface of the guide seat mechanism 3. A longitudinal groove is opened inside the guide frame assembly 3012. A longitudinally arranged servo push rod 3013 is fixedly connected inside the longitudinal groove. A bracket assembly 3014 is fixedly connected on the top surface of the servo push rod 3013.

[0027] By opening a guide groove 101 on the assembly table 1 and installing a guide ring assembly 301, and connecting the guide seat mechanism 3 to the guide ring assembly 301, a basic rotatable structure is constructed, which provides a basis for subsequent multi-angle adjustment of the refrigeration component 2015 and facilitates adjustment of the welding position.

[0028] See Figures 2-5 The top of the bracket assembly 3014 is provided with an arc-shaped groove for placing water pipe fittings, and a servo motor 1011 is installed on the bottom surface of the assembly table 1.

[0029] The arc-shaped groove at the top of the bracket assembly 3014 facilitates the placement of water pipe fittings, and the servo motor 1011 installed at the bottom of the assembly table 1 provides power for the operation of the tooling, ensuring the stability of the fittings during welding and the operation of the tooling.

[0030] See Figures 1-3 There are four servo motors 1011. The four servo motors 1011 are respectively installed at the four corners of the bottom surface of the assembly table 1. The top output shaft of the four servo motors 1011 is also equipped with drive gears 1012.

[0031] By installing four servo motors 1011 at the four corners of the bottom surface of the assembly table 1, and installing drive gears 1012 on the output shaft, more stable power can be provided to ensure the smooth operation of the tooling and provide power support for the smooth progress of welding work.

[0032] See Figures 5-6 The drive gear 1012 meshes with the guide gear assembly 3011 fixedly connected to the outer peripheral surface of the guide seat mechanism 3, and the support mechanism 2 is fixedly connected to the bottom end surface of the assembly table 1.

[0033] The drive gear 1012 meshes with the guide gear assembly 3011 for transmission, and in conjunction with the bracket mechanism 2, enables the guide seat mechanism 3 to rotate, thereby achieving angle adjustment of the refrigeration component 2015 to meet different welding angle requirements.

[0034] See Figures 1-2 There are two support mechanisms 2, and the two support mechanisms 2 are fixedly connected in a straight line array to the front and rear sides of the bottom surface of the assembly table 1.

[0035] The tooling is fixed in a linear array by two support mechanisms 2 on the front and rear sides of the bottom end of the assembly table 1, which enhances the overall stability of the tooling, ensures that the tooling will not shake during the welding process, and improves the welding accuracy.

[0036] See Figures 3-4 Both support components 201 are fixedly connected to the inner side of the two support mechanisms 2. The main body of the support component 201 is inclined, and the base plate component 2011 is also fixedly connected to the inner side of the support component 201.

[0037] The support assembly 201 and the base plate assembly 2011 on the inner side of the bracket mechanism 2 further stabilize the tooling structure, provide solid support for components such as the lifting push rod 2012, and ensure the reliability of the tooling during operation.

[0038] See Figures 1-2 The top of the base plate assembly 2011 is fixedly connected to a lifting push rod 2012, the top of the lifting push rod 2012 is fixedly connected to a tray assembly 2013, and the inner side of the tray assembly 2013 is fixedly connected to a magnetic ring assembly 2014 for adsorbing the refrigeration accessory 2015.

[0039] The lifting push rod 2012, tray assembly 2013, and magnetic ring assembly 2014 at the top of the base plate assembly 2011 can adjust the height of the refrigeration component 2015 and attract and fix the component, which facilitates welding operations and improves welding efficiency and quality.

[0040] When using this welding fixture to weld refrigeration equipment components, the operator first connects the fixture to the power supply and starts the servo motors 1011 installed at the four corners of the bottom end face of the assembly table 1. After the servo motors 1011 start running, their top output shaft synchronously drives the drive gears 1012 installed on them to rotate.

[0041] The drive gear 1012 meshes tightly with the guide gear assembly 3011 arranged in a ring array on the outer circumference of the guide mechanism 3. This meshing relationship allows the guide mechanism 3 to rotate smoothly around its own central axis under the driving force of the drive gear 1012. Since the guide mechanism 3 is fixedly connected to the guide ring assembly 301, and the guide ring assembly 301 is installed inside the annular guide groove 101 pre-cut on the top surface of the assembly table 1, the guide groove 101 plays a precise limiting and guiding role for the guide ring assembly 301. This ensures that the guide mechanism 3 rotates smoothly along a specific trajectory during rotation without deviation or shaking. This enables precise horizontal angle adjustment of the refrigeration accessory 2015 installed on the guide mechanism 3 to meet the diverse requirements of different welding processes for welding angle.

[0042] When it is necessary to adjust the vertical position of the refrigeration component 2015, the operator activates the servo push rod 3013 inside the guide assembly 3012. The servo push rod 3013 is longitudinally fixed in the longitudinal groove of the guide assembly 3012, and its top end is firmly connected to the bracket assembly 3014. When the servo push rod 3013 is working, it converts electrical energy into linear mechanical energy through its internal mechanical structure, pushing the bracket assembly 3014 to move up and down along the longitudinal groove of the guide assembly 3012. Since the water pipe fittings or other related refrigeration components 2015 of the refrigeration equipment are placed in the specially designed arc groove at the top of the bracket assembly 3014, the up and down movement of the bracket assembly 3014 drives the refrigeration component 2015 to rise and fall in the vertical direction, thereby achieving the purpose of adjusting the welding height, ensuring that the welding operation can be carried out at the appropriate height, and improving the accuracy and quality of the welding.

[0043] When placing the refrigeration component 2015, the operator first places it on the tray assembly 2013. The tray assembly 2013 is connected to the base plate assembly 2011 via the lifting push rod 2012. The base plate assembly 2011 is fixedly installed on the inclined support assembly 201, which is located inside the bracket mechanism 2. If the height of the refrigeration component 2015 needs to be adjusted before welding, the operator can activate the lifting push rod 2012. When the lifting push rod 2012 is working, it also uses its internal mechanical structure to transfer electricity... It can be converted into linear driving force to push the tray assembly 2013 up or down, thereby changing the height of the refrigeration component 2015. At the same time, the magnetic ring assembly 2014 installed inside the tray assembly 2013 will play a role. It can use its own magnetism to tightly attract the refrigeration component 2015, generating sufficient attraction force to prevent the refrigeration component 2015 from being displaced during the welding process due to the vibration of the tooling or other external forces. This ensures the stability of the position of the refrigeration component 2015 during the welding process and provides a strong guarantee for high-quality welding operations.

[0044] The stability of the entire tooling is ensured by two support mechanisms 2, which are fixedly connected in a linear array to the front and rear sides of the bottom surface of the assembly table 1. They provide basic support for the entire tooling. The support component 201 and the base plate component 2011 inside the support mechanism 2 further enhance the stability of the tooling. The inclined setting of the support component 201 increases the support area and stability of the tooling, while the base plate component 2011 provides a stable installation foundation for components such as the lifting push rod 2012. This ensures that the entire tooling will not shake due to equipment vibration, component movement, or other factors during the welding process, providing a reliable and stable working platform for welding work and helping to improve welding accuracy and quality.

[0045] In summary, the device, by providing the support component 201, can achieve stable reinforcement of the support mechanism 2.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
