Description

Technical Field

[0001] This utility model relates to the field of spiral component processing equipment, specifically a precision machining equipment for the guide surface of a spiral guide component. Background Technology

[0002] Spiral guide vanes are a common type of flow guiding component in burner equipment. They are installed at the end of the burner. When natural gas or other fuels pass through the spiral guide vane, the flow channels within the vane cause the fuel to diffuse at the burner port and come into full contact with oxygen, thus achieving better combustion. (See attached diagram in the instruction manual.) Figure 6 The diagram shows the structure of the spiral guide component. Because multiple spiral guide grooves are evenly spaced on its side, the inner end face of each groove is the guide surface. During the machining process, it is crucial to ensure the smooth and gentle end face of the spiral guide grooves to effectively guide the fuel rotation. If the interior is uneven or has burrs, it will affect the guide effect, thus impacting the burner's combustion efficiency. However, this guide surface is an arc structure with a spiral opening, making it difficult to perform precise machining on its inner end face using traditional methods. Furthermore, during the spiral flow of natural gas, backfire occurs during the initial burner ignition due to intense contact between oxygen and natural gas. This causes the high-temperature flame to directly impact the end face of the spiral guide groove. If burrs are present inside the groove at this time, they will melt under high temperature, damaging the end face of the spiral guide groove and hindering the burner's long-term operation.

[0003] To address the aforementioned issues, a precision machining device for the guide surface of a spiral guide component is proposed. This device facilitates the machining of the guide groove of the spiral guide component, ensuring that the inner end face of the guide groove is smooth and complete, without any burrs, thus guaranteeing the normal and continuous combustion of the subsequent burner. Utility Model Content

[0004] The purpose of this utility model is to provide a device for precision machining of the guide surface of a spiral guide component, which can perform arc surface machining on the guide groove of the spiral guide component, so that the guide groove can guide and transport fuel more smoothly and will not affect the normal combustion of fuel due to burrs or unevenness inside, thereby ensuring the long-term use of the burner.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A precision machining device for the flow guide surface of a spiral guide includes a vertical positioning component and a horizontal grinding component. The vertical positioning component is located on both sides of the spiral guide, and the horizontal grinding component is located on the outer side of the spiral guide. A relative rotation mechanism is provided between the vertical positioning component and the horizontal grinding component to allow the vertical positioning component and the horizontal grinding component to rotate relative to each other.

[0007] Vertical positioning component: includes a top cap fixing part and a bottom surface fixing part, wherein the top cap fixing part and the bottom surface fixing part respectively abut against the top cap and bottom surface of the spiral guide component; and a hydraulic telescopic mechanism is provided at the position of the top cap fixing part or the bottom surface fixing part, wherein the spiral guide component is limited and positioned between the top cap fixing part and the bottom surface fixing part by the hydraulic telescopic mechanism;

[0008] Horizontal grinding component: includes a grinding base and a grinding end. A synchronous telescopic shaft is provided on the grinding base, and the telescopic end of each synchronous telescopic shaft is set towards the center of the grinding base. The grinding end is set at the end of each synchronous telescopic shaft. The grinding end comes into contact with the guide groove through the extension and retraction of multiple synchronous telescopic shafts.

[0009] The top cap fixing part includes a fixed top cap, and an arc-shaped protrusion is provided inside the fixed top cap. The adjacent arc-shaped protrusions are arranged opposite each other, and multiple sets of the arc-shaped protrusions arranged opposite each other are arranged in a circumferential array inside the fixed top cap.

[0010] The bottom fixing part is a frosted support platform, and the diameter of the frosted support platform is smaller than the bottom diameter of the spiral guide.

[0011] The synchronous telescopic shaft includes a screw and a sliding base. The sliding base is slidably positioned above the screw and is threadedly engaged with the screw. When the screw rotates, it drives the sliding base to slide back and forth along the screw's direction. Each screw of the multiple synchronous telescopic shafts is individually connected to a drive motor, and all the drive motors are connected to the same control system.

[0012] The grinding end includes an end base and a spherical grinding head, the spherical grinding head being rotatably limited within the end base; an elastic buffer is provided within the end base, and the spherical grinding head contacts the elastic buffer.

[0013] A return channel is provided inside the end base. The return channel is connected to the rear space of the spherical grinding head. The return channel is connected to a lubricating fluid circulation system, which delivers lubricating fluid towards the spherical grinding head position on the end base.

[0014] The spherical grinding head has a smooth spherical end.

[0015] The relative rotation mechanism includes a telescopic rotary motor, which is connected to the lower end of the bottom fixing part of the vertical positioning member; and a servo cylinder is connected to the upper end of the top cap fixing part, the rear end of the servo cylinder is rotatably fixed, and the telescopic end is connected to the top cap fixing part.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This device is designed with vertical positioning components and horizontal grinding components to enable the processing of the spiral guide component.

[0018] 1. Because the flow guide groove of the spiral guide needs to be machined to ensure its position is limited. To facilitate centering the spiral guide within the burner during installation, its upper end has an arc-shaped structure. Therefore, for this device, to ensure stability during the machining of the spiral guide, a vertical positioning component is incorporated. This vertical positioning component works in conjunction with both ends of the spiral guide, effectively limiting their positions and ensuring stable subsequent machining operations.

[0019] 2. The guide groove of the spiral guide component has an arc-shaped structure, and the guide groove is spirally arranged on the spiral guide component. Therefore, it is necessary to ensure the effectiveness and stability of the processing of the guide groove. The grinding base and grinding end are controlled by a synchronous telescopic shaft to maintain contact between the grinding end and the guide groove. During use, the synchronous telescopic shaft drives multiple grinding ends to contact each guide groove, thereby limiting the lateral position of the spiral guide component. Furthermore, under the control of the relative rotation mechanism, when the vertical positioning component and the lateral grinding component rotate relative to each other, the grinding end moves up and down while in contact with the guide groove, thereby pressing and flattening the inner end face of the guide groove under the abutment force, thus achieving the processing operation of the inner wall of the guide groove.

Detailed Implementation

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0029] As shown in the attached diagram of the instruction manual. Figure 6 The diagram shows the structure of the spiral guide 1. The spiral guide 1 serves as a flow-diverting element at the end of the burner, spirally diverting the natural gas or other fuel delivered to its end. This slows down the high-velocity fuel and diffuses it at the end, allowing the fuel to come into contact with more oxygen and achieve more complete combustion, thus effectively utilizing the fuel. This requires the guide groove of the spiral guide 1 to be smooth and even, free from burrs or unevenness, which would affect the normal flow of natural gas or other fuel. Furthermore, if burrs or other defects are present inside the guide groove, they will directly burn the uneven areas during ignition and backflow, causing combustion damage and hindering the long-term use of the burner.

[0030] Therefore, based on the background technology and the aforementioned technical problems, a precision machining equipment for the guide surface of a spiral guide component is provided to perform machining operations on the inside of the guide groove of the spiral guide component 1.

[0031] The device includes vertical positioning components and horizontal grinding components. The vertical positioning components are positioned on both sides of the spiral guide component 1, and the horizontal grinding components are positioned on the outer side of the spiral guide component 1. A relative rotation mechanism is provided between the vertical positioning components and the horizontal grinding components to allow them to rotate relative to each other. When the device is set up, the vertical positioning components are positioned on both sides of the spiral guide component 1 to position it. The horizontal grinding components are positioned on the outer side of the spiral guide component 1 and, through the synchronous telescopic shaft 6, drive the grinding end 5 to act on the guide groove of the spiral guide component 1, thereby creating an interaction between the grinding end 5 and the guide groove of the spiral guide component 1. When grinding is required on the guide groove of the spiral guide component 1, the upper and lower ends of the spiral guide component 1 are first positioned with the vertical positioning components to fix its position. Secondly, the transverse grinding component is positioned on the outer side of the spiral guide component 1, allowing the grinding end 5 of the transverse grinding component to interact with the guide groove. Then, a relative rotation mechanism causes the vertical positioning component and the transverse grinding component to rotate relative to each other. This allows the grinding end 5 of the transverse grinding component to move along the guide groove while being in contact with it, thus achieving the purpose of processing the guide groove. Because the dimensions of the grinding end 5 are closely matched to the inside of the guide groove, when burrs or unevenness appear inside the guide groove, the grinding end 5 continuously moves along the guide groove, achieving the purpose of grinding the uneven areas inside the guide groove.

[0032] The above structure is designed and further optimized as follows:

[0033] Vertical positioning components:

[0034] Because the spiral guide 1 is designed for easy positioning and installation within the burner, most spiral guide 1 have an arc-shaped end at the inner end to ensure proper positioning. However, during the grinding and machining of the spiral guide 1, especially the processing of the guide groove, it is necessary to ensure that the spiral guide 1 is effectively fixed without damaging the arc-shaped end, so as not to affect the effective installation of the spiral guide 1 in the burner.

[0035] The device includes a top cap fixing part 2 and a bottom surface fixing part 3, which respectively abut against the top cap and bottom surface of the spiral guide component 1. A hydraulic telescopic mechanism is provided at either the top cap fixing part 2 or the bottom surface fixing part 3 to limit the spiral guide component 1 to a position between the top cap fixing part 2 and the bottom surface fixing part 3. When fixing the position of the spiral guide component 1, in addition to effectively fixing the top cap end of the spiral guide component 1, it is also necessary to ensure that the outer surface of the spiral guide component 1 is not squeezed or occupied in the fixed state, so as to ensure that the processing of the guide groove has suitable processing space. Therefore, the top cap fixing part 2 and the bottom surface fixing part 3 are respectively provided to specifically limit and fix the upper and lower ends of the spiral guide component 1 to meet the fixed installation requirements of the spiral guide component.

[0036] The top cap fixing part 2 is configured as follows: the top cap fixing part 2 includes a fixed top cap 7, and an arc-shaped protrusion 8 is provided inside the fixed top cap 7. The adjacent arc-shaped protrusions 8 are arranged opposite each other, and multiple sets of the opposite arc-shaped protrusions 8 are arranged in a circumferential array inside the fixed top cap 7. When the arc-shaped end of the spiral guide 1 is engaged with the fixed top cap 7, the arc-shaped protrusion 8 is in contact with the arc-shaped end of the spiral guide 1. Here, when the arc-shaped protrusions 8 are set, two arc-shaped protrusions 8 are arranged opposite each other, so that when the arc-shaped end is in contact with the adjacent arc-shaped protrusion 8, the arc-shaped end that is abutting against the arc-shaped protrusion 8 has arc-shaped protrusions 8 on both the left and right sides, so that the fixed top cap 7 can effectively restrict the upper position of the spiral guide 1. Meanwhile, because the raised end face of the arc protrusion 8 is arc-shaped, the contact area of ​​the arc protrusion 8 when it comes into contact with the arc end is smaller. This ensures that the upper position of the spiral guide 1 is fixed while the arc end has a smaller contact area, so as to avoid greater wear caused by more arc end and more area coming into contact with the fixed equipment.

[0037] The bottom fixing part 3 is configured as follows: the bottom fixing part 3 is a frosted support platform 9, and the diameter of the frosted support platform 9 is smaller than the bottom diameter of the spiral guide 1; that is, it is ensured that after the frosted support platform 9 comes into contact with the bottom of the spiral guide 1, the position of the frosted support platform 9 will not exceed the bottom range of the spiral guide 1, and the normal processing of the guide groove of the spiral guide 1 will not be affected by the setting of the frosted support platform 9.

[0038] Horizontal grinding parts:

[0039] The system includes a grinding base 4 and a grinding end 5. A synchronous telescopic shaft 6 is mounted on the grinding base 4, with the telescopic end of each synchronous telescopic shaft 6 facing the center of the grinding base 4. The grinding end 5 is located at the end of each synchronous telescopic shaft 6. The grinding end 5 contacts the guide groove through the extension and retraction of the multiple synchronous telescopic shafts 6. Each synchronous telescopic shaft 6 includes a screw 10 and a sliding base 11. The sliding base 11 is slidably positioned above the screw 10 and threadedly engaged with it. When the screw 10 rotates, it drives the sliding base 11 to slide back and forth along the direction of the screw 10. Each screw 10 of the multiple synchronous telescopic shafts is individually connected to a drive motor 12, and all drive motors 12 are connected to the same control system. During the processing of the guide groove, the spiral guide 1 is fixed at the center of the grinding base 4. Then, the control system controls multiple drive motors 12 to rotate synchronously, causing the screw 10 to rotate and drive the sliding base 11 to move. In this state, the grinding end 5 at the end of the sliding base 11 gradually approaches the spiral guide 1 and is guided into the guide groove of the spiral guide 1, so as to achieve the cooperation between the grinding end 5 and the guide groove. It should be noted here that, in order to ensure that the force on the guide groove of the spiral guide 1 is consistent in all directions, so as to ensure that each guide groove of the spiral guide 1 can be effectively ground, a synchronous telescopic shaft 6 must be set here. This ensures that after each grinding end 5 acts on the guide groove, the force on the guide groove is consistent, and the problem of one guide groove having a weak grinding force while another guide groove has a strong grinding force is not present.

[0040] The grinding head 5 includes an end base 13 and a spherical grinding head 14, which is rotatably and limitedly disposed within the end base 13. An elastic buffer 15 is disposed within the end base 13, and the spherical grinding head 14 contacts the elastic buffer 15. A return channel 16 is disposed inside the end base 13, which communicates with the rear end space of the spherical grinding head 14. The return channel 16 is connected to a lubricating fluid circulation system, through which lubricating fluid is delivered towards the spherical grinding head 14 on the end base 13. The spherical grinding head 14 has a smooth spherical end. Because the wear resistance of the spherical grinding head 14 and its ability to be used for a long time need to be ensured when grinding the guide channel, it is necessary to avoid the wear problem of the spherical grinding head 14 during use. Therefore, an elastic buffer 15 is set in the end base 13 so that the rear end of the spherical grinding head 14 can have a certain elastic buffer and maintain the specified force applied to the guide channel, so as to ensure that the spherical grinding head 14 maintains the specified force while ensuring that the inner end face of the spherical grinding head 14 is not subjected to large wear.

[0041] Relative rotation mechanism:

[0042] The relative rotation mechanism includes a telescopic rotary motor, which is connected to the lower end of the bottom fixing part 3 of the vertical positioning member; and a servo cylinder 17 is connected to the upper end of the top cap fixing part 2, with its rear end fixed and its telescopic end connected to the top cap fixing part 2. The telescopic rotary motor internally comprises a lead screw drive mechanism and a rotary motor. The rotary motor drives the lead screw drive mechanism to rotate, causing the lead screw drive mechanism to move along the spiral slide rail provided on the inner wall of the outer casing, thereby realizing the forward and backward telescopic rotation of the lead screw. This telescopic rotary motor is quite common and is a widely used motor drive device. While moving the spiral guide 1 up and down, it is also necessary to ensure that the position of the spiral guide 1 is fixed. Therefore, a servo cylinder 17 is set at the upper end of the top cap fixing part 2. The servo cylinder 17 can directly apply pressure to the top cap fixing part 2. When the telescopic rotary motor moves the spiral guide 1 up and down, the control system inside the servo cylinder can sense the internal pressure, so that the force exerted by the telescopic end of the servo cylinder on the top cap fixing part 2 remains constant, thereby achieving the purpose of stably fixing the spiral guide 1. If the servo cylinder 17 is set to other ordinary cylinders, it is necessary to connect a control system and connect it to the telescopic rotary motor. Through the code programming inside the control system, the telescopic rotary motor and the cylinder can move synchronously in telescopic position, thereby achieving the purpose of stably fixing the spiral guide 1.

[0043] Therefore, the installation of a precision machining equipment for the guide surface of a spiral guide can facilitate the machining of the guide groove of the spiral guide 1, making the end face inside the guide groove smooth and complete, without burrs, to ensure the normal and continuous combustion of the subsequent burner.
