Description

Technical Field

[0001] This utility model belongs to the field of burner manufacturing technology, specifically relating to a device for testing the pressing of welding rings and the assembly of turbulence rings during the burner assembly process. Background Technology

[0002] In the burner manufacturing and assembly process, the turbulence ring and the weld ring are two key components. Multiple turbulence rings are typically stacked within the burner housing at specific locations, and their main function is to optimize the mixing of fuel gas and air, ensuring combustion stability. The weld ring, on the other hand, is press-fitted onto the turbulence ring assembly and ultimately secured through a welding process.

[0003] Currently, the mainstream production process for this step is typically a multi-step operation: first, operators manually place a specified number of turbulence rings into the housing; then, the welding rings are pressed and welded. However, this manual placement method presents significant quality risks: operators may overlook placing a turbulence ring due to negligence, resulting in an insufficient number of turbulence rings after assembly. This directly leads to deterioration of burner performance and may subsequently cause safety hazards. On the other hand, if manual inspection is used separately, it is not only inefficient but also prone to omissions and false positives, increasing product quality risks.

[0004] Therefore, there is an urgent need for an integrated device that can simultaneously achieve weld ring clamping and turbulent ring detection to solve the problems of low assembly efficiency and insufficient detection reliability in existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a welding ring pressing device with a turbulence ring missing detection function. It can determine whether the turbulence ring has been correctly placed while pressing the welding ring, resulting in high product yield and high detection reliability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a welding ring pressing device with turbulence ring leakage detection function, comprising:

[0007] The fixture body has a pressing surface on its lower surface for pressing the welding ring, and a through hole is provided on the fixture body for inserting the burner's string tube, and the diameter of the through hole is smaller than the inner diameter of the welding ring.

[0008] The guide tube is fixed inside the through hole;

[0009] A conductor is slidably mounted inside the guide tube along the axial direction of the guide tube, with the bottom of the conductor extending through the guide tube and the upper end of the conductor having a protrusion for limiting its own fall.

[0010] An insulating sleeve is wrapped around the bottom of the conductor, and the outer diameter of the insulating sleeve is adapted to the inner diameter of the conduit.

[0011] A conductive sheet is electrically connected to the bottom of the conductor and is driven to rise and fall by the conductor. The conductive sheet is in close contact with the insulating sleeve, and the diameter of the conductive sheet is smaller than the diameter of the insulating sleeve.

[0012] The detection lamp has one end electrically connected to the conductor and the other end electrically connected to the workbench surface;

[0013] When the conductive burner is placed on the workbench, the fixture body is pressed down so that the pressing surface fits and presses the welding ring, and then the conductor is pressed down to drive the conductive sheet to descend synchronously.

[0014] If the conductive sheet contacts the turbulence coil inside the burner tube, a closed loop is formed by the detection lamp, conductor, conductive sheet, turbulence coil, burner, and conductive work surface, and the detection lamp lights up; if the turbulence coil is missing, the conductive sheet cannot contact the turbulence coil, the loop is broken, and the detection lamp does not light up.

[0015] Furthermore, the upper surface of the fixture body is provided with a handle.

[0016] Furthermore, the fixture body includes a first conductive plate, an insulator, and a second conductive plate arranged vertically.

[0017] Furthermore, the conductive sheet is pressed onto the insulating sleeve by a conductive connector, and the conductive sheet is electrically connected to the conductor by the conductive connector.

[0018] Furthermore, the conductive connector is a metal nut.

[0019] Furthermore, the conductor is made of copper.

[0020] Furthermore, the number of through holes is multiple, and they are symmetrically distributed.

[0021] Furthermore, a reset spring is sleeved on the conductor, with the lower end of the reset spring supported on the guide tube and the upper end abutting against the boss.

[0022] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0023] This utility model relates to a welding ring pressing device with a turbulence ring missing detection function, which integrates welding ring pressing and turbulence ring detection functions into one. The operator can complete the pressing of the welding ring and the detection of missing turbulence rings in one pressing of the fixture, which greatly shortens the assembly time, improves production efficiency, reduces the dependence on the operator's experience, and improves the product yield and assembly efficiency.

[0024] Secondly, through a closed-loop detection mechanism consisting of a detection lamp, conductor, conductive sheet, turbulence coil, burner, and workbench, the circuit is connected when the conductive sheet contacts the turbulence coil, and the detection lamp lights up; otherwise, the detection lamp does not light up. This allows for a direct and reliable determination of whether the turbulence coil is missing or misaligned, effectively avoiding the problems of missed or false detections in manual inspection, ensuring the consistency of burner assembly quality, convenient operation, and high practical value.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] This invention provides a welding ring pressing device with a turbulence ring missing installation detection function to solve the problem in the prior art that it is impossible to quickly and effectively check whether the turbulence ring is installed in place after the welding ring is pressed, which affects product quality and assembly efficiency.

[0038] See Figure 1 The purpose of this utility model is to use a fixture to press the welding ring 20 sleeved on the outside of the serial tube 9, and to detect whether the turbulence ring 21 located inside the serial tube 9 is properly assembled or missing.

[0039] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 2 to 5 An embodiment of this application provides a welding ring pressing device with turbulence ring leakage detection function, comprising a fixture body 1, a guide tube 2, a conductor 3, an insulating sleeve 4, a conductive sheet 5, and a detection lamp 6.

[0040] See Figure 3 and Figure 6 The fixture body 1 shown has six through holes 11, arranged in two rows of three. These through holes 11 are for inserting the tubing 9, so the diameter of the through holes 11 is smaller than the inner diameter of the welding ring 20. The number of through holes 11 is also adapted to the number of tubing 9. The lower surface of the fixture body 1 has a clamping surface 10 for clamping the welding ring 20. The clamping surface 10 is horizontal, which allows for effective clamping of the welding ring located on the burner.

[0041] In addition, a U-shaped handle 7 is provided on the fixture body 1 to facilitate applying force to the fixture body 1 and make actual operation easier.

[0042] See Figure 4 5 and 9, the guide tube 2 is vertically fixed inside the through hole 11; the conductor 3 is slidably engaged inside the guide tube 2 along the axial direction of the guide tube 2, and the bottom of the conductor 3 extends through the guide tube 2; and a boss 30 is provided at the upper end of the conductor 3 to prevent the conductor 3 from falling directly downwards. The conductor 3 is made of a conductive material, which is copper in this embodiment. Copper has excellent conductivity, ensuring the sensitivity of the circuit continuity detection and avoiding false judgments that the lamp will not light up due to excessive resistance.

[0043] The insulating sleeve 4 wraps around the bottom of the conductor 3, and the outer diameter of the insulating sleeve 4 matches the inner diameter of the serial tube 9. The lower end of the conductor 3 passes through the conductive sheet 5, and then the conductive sheet 5 is locked to the end of the conductor 3 by the conductive connector 31. At the same time, as the conductive connector 31 is tightened, the conductive sheet 5 is reliably pressed and fixed on the insulating sleeve 4, and the conductive sheet 5 is driven by the conductor 3 to rise and fall synchronously. During operation, after the turbulence coil 21 comes into contact with the conductive sheet 5, the conductive sheet 5 can conduct electricity with the conductor 3. In addition, the diameter of the conductive sheet 5 is smaller than the diameter of the insulating sleeve 4 to avoid the conductive sheet 5 directly contacting the serial tube 9 for conduction, or the conductor 3 directly contacting the serial tube 9 for conduction.

[0044] One end of the detection lamp 6 is electrically connected to the conductor 3, and the other end is electrically connected to the workbench surface. When the conductive sheet 5 comes into contact with the turbulence coil 21 in the burner 8, the detection lamp 6, conductor 3, conductive connector 31, conductive sheet 5, turbulence coil 21, burner 8 and conductive workbench surface form a closed circuit, and the detection lamp 6 will light up. This indicates that the turbulence coil 21 is not missing. If it does not light up, it indicates that the turbulence coil 21 is missing.

[0045] Furthermore, the fixture body 1 includes, from top to bottom, a first conductive plate 12, an insulator 13, and a second conductive plate 14. Since the burner 8 is also conductive, the use of the insulator 13 in the middle can prevent the non-detection circuit from conducting electricity and causing the detection lamp 6 to light up.

[0046] Furthermore, the conductive connector 31 is a metal nut, which connects to the bottom of the conductor 3 while pressing the conductive sheet 5 onto the insulating sleeve 4.

[0047] Furthermore, a return spring 32 is also fitted onto the conductor 3. The return spring 32 is housed inside the guide tube 2, with its lower end supported at the bottom of the guide tube 2 and its upper end abutting against the lower surface of the boss 30. When the conductor 3 is manually pressed down and released, the conductor 3 and the conductive sheet 5 can automatically return to their initial height under the action of the return spring 32.

[0048] The use of this device, combined with the burner assembly process, involves the following specific steps:

[0049] S1: Place the burner with the turbulence coil already placed on it smoothly on the conductive workbench, ensuring that the burner shell is in close contact with the workbench surface.

[0050] S2: The operator holds the handles 7 of the fixture body 1 with both hands, aligns the through hole 11 of the fixture body 1 with the serial tube 9 of the burner 8, and slowly lowers the fixture body 1 to ensure that the serial tube 9 is smoothly inserted into the through hole 11.

[0051] S3: Continue to press down the handle 7 until the pressing surface 10 on the lower surface of the fixture body 1 is completely in contact with the upper surface of the welding ring 20. Apply a little more pressure and hold for a period of time to ensure that the welding ring 20 is pressed into the designated assembly position of the burner without any offset or tilting, thus completing the welding ring pressing process.

[0052] S4: Then, the upper end of the conductor 3 is pressed down vertically by the operator, causing the conductor 3 to slide down along the guide tube 2. At the same time, the conductive sheet 5 descends synchronously with the conductor 3 until the conductive sheet 5 contacts the turbulence coil 21 in the serial tube 9, and the turbulence coil detection process is performed.

[0053] S5: If the test light 6 is lit, it means that a closed loop is formed from the test light 6, conductor 3, conductive connector 31, conductive sheet 5, turbulence coil 21, burner 8, workbench surface and back to the test light 6. The turbulence coil 21 has been installed correctly and can proceed to the next process.

[0054] If indicator light 6 does not light up, it indicates that the circuit is broken, or that turbulence coil 21 is missing or misaligned. Operation must be stopped immediately, and the coil must be reinstalled or adjusted before retesting.

[0055] In summary, the pressing device of this utility model can simultaneously realize the pressing of welding rings and the detection of turbulent rings through a single fixture. It is convenient and labor-saving to operate, saves process switching time, significantly improves assembly efficiency, and ensures product quality.

[0056] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
