Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically to a flange processing positioning structure. Background Technology

[0002] When machining a flange, multiple bolt holes and positioning holes need to be drilled evenly along its axial direction. Existing machining methods typically use bench drills or vertical radial drilling machines to machine the bolt holes. Therefore, when the cutting tool contacts the flange, the rotational force of the tool causes the flange to shift position, resulting in inaccurate positioning and perpendicularity of the bolt holes. To address these shortcomings, the existing technology CN 222660815U specification, paragraph 0030, states: "The flange to be machined is placed at the center of the upper wall of the workbench. Then, by rotating the bidirectional screw, symmetrically arranged sliding screw seats move towards each other. The sliding screw seats cause symmetrically arranged clamping blocks to move closer together to clamp and fix the flange. In the initial state, the side of the eccentric wheel shaft furthest from the rotating shaft is housed in the locking groove near the arc-shaped inner wall, while the side of the eccentric wheel shaft closest to the rotating shaft is located on the straight inner wall of the locking groove. When the clamping blocks are in contact with the flange sidewall and clamp the flange, the flange pushes the eccentric wheel shaft to engage with the limiting protrusion, which limits the side of the eccentric wheel shaft furthest from the rotating shaft."

[0003] The aforementioned technical solution uses two clamping blocks that fit together to passively contact the flange within the clamping blocks with the eccentric wheel, thereby locking the flange using the eccentric wheel and the limiting protrusion. While this does prevent flange misalignment after locking, the specification sheet of the aforementioned prior art... Figure 1 As shown, a fixing plate is installed below the clamping block. The fixing plate is an immutable structure, which means that the flange diameter must be greater than the distance between the fixing plate and the eccentric wheel inside the clamping block. Otherwise, when the two clamping blocks are closed, the flange will be too small to hold the flange. Similarly, if the flange diameter is too large, exceeding the inner diameter of the clamping block, the eccentric wheel will not be able to hold the flange at all during actual clamping. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a flange processing positioning structure that has advantages such as the ability to clamp flanges of different sizes, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a flange processing positioning structure, including a processing table in which a flange is placed at the center of the top surface, slide rails installed at both ends of the front and rear sides of the processing table, the slide rails being two sets of four in total, the four slide rails converging in an "X" shape toward the center area of ​​the top surface of the processing table, and a slider slidingly connected to the inner side of the slide rails, a positioning pad being installed on the front wall of the slider near the center of the top surface of the processing table;

[0008] The top surface of the slider is also connected to a connecting rod, and the side wall of the connecting rod is slidably connected to a horizontal rail. There are two horizontal rails, which are arranged horizontally above the front and rear ends of the processing table. The inner end of each horizontal rail is slidably connected to the side wall of a connecting rod. Each of the two horizontal rails is connected to a linkage plate. The two linkage plates are connected by a double-ended screw. The two ends of the double-ended screw pass through the linkage plate and are threaded to it. The tail end of the screw is connected to the drive structure.

[0009] As a preferred embodiment of this utility model, there are two double-ended screws, which are symmetrically arranged at both ends of the linkage plate. The double-ended portions of the double-ended screws penetrate the linkage plate and form a threaded connection with it. The drive structure includes worm gears located at the rear end of the processing table and fixedly connected to the tail end of the double-ended screws. The bottoms of the two worm gears mesh with a worm. The front and rear threads of the worm are opposite. The tail end of the worm is fixedly connected to a reduction motor through a coupling to form a drive.

[0010] As a preferred embodiment of this utility model, the connecting rod is relatively perpendicular to the top surface of the processing table, and the bottom of the connecting rod is fixedly connected to the top surface of the slider by welding or bolts.

[0011] As a preferred embodiment of this utility model, the positioning pad is a block made of rubber, and the rear wall of the positioning pad is fixedly connected to the front wall of the slider by an interlocking method.

[0012] As a preferred technical solution of this utility model, the positioning pad is a rectangular body made of hard plastic, and the front wall of the positioning pad is also provided with a notch, and a rubber column is fixedly installed inside the notch.

[0013] As a preferred embodiment of this utility model, the rubber columns are installed at intervals inside the recess, and there are gaps between the multiple rubber columns.

[0014] Compared with the prior art, this utility model provides a flange processing positioning structure, which has the following beneficial effects:

[0015] 1. This utility model uses sliders that converge relative to each other within four "X"-shaped slide rails. Therefore, while the connecting rod moves longitudinally, it also moves laterally closer to each other inside the horizontal rail. Finally, as the linkage plates move closer to each other, the four sliders converge along the trajectory of converging at the four corners of the top surface of the processing table to form a four-corner positioning clamp for the flange placed at the center of the top surface of the processing table. This not only enables centering but also four-point positioning, ensuring the stability of the clamping. At the same time, the sliders converge and clamp from four angles respectively, so that the flange can be clamped regardless of its diameter, whether it is large or small. This achieves the beneficial effect of improving the positioning structure so that it can clamp flanges of different sizes. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-5 A flange processing positioning structure includes a processing table 1 on which a flange is placed at the center of the top surface. The processing table 1 is equipped with slide rails 2 at both ends of the front and rear sides. There are two sets of four slide rails 2. The four slide rails 2 converge toward the center area of ​​the top surface of the processing table 1 in an "X" shape. A slider 201 is slidably connected to the inner side of the slide rail 2. A positioning pad 202 is installed on the front wall of the slider 201 near the center of the top surface of the processing table 1.

[0026] The top surface of the slider 201 is also connected to the connecting rod 3. The side wall of the connecting rod 3 is slidably connected to the horizontal rail 4. There are two horizontal rails 4, which are arranged horizontally above the front and rear ends of the processing table 1. The inner end of each horizontal rail 4 is slidably connected to the side wall of the connecting rod 3. The two horizontal rails 4 are each connected to the linkage plate 5. The two linkage plates 5 are connected by a double-ended screw 6. The two ends of the double-ended screw 6 pass through the linkage plate 5 and are threaded to it. The tail end of the screw 6 is connected to the drive structure.

[0027] Place the flange to be processed at the center of the top surface of processing table 1, as per the instruction manual. Figure 1 As shown, a circular mark is set at the center of the top surface of the processing table 1. Precise alignment is not required to activate the drive mechanism. As the drive mechanism drives the double-headed screw 6 to rotate, as shown in the instruction manual. Figure 1 As shown, two double-ended screws 6 are threadedly connected to both sides of the two linkage plates 5 respectively. The threads at both ends of the double-ended screws 6 are opposite. Therefore, when the double-ended screws 6 begin to rotate in the forward direction, the threads at both ends move relative to the threaded holes at the through-holes of the linkage plates 5. At this time, as shown in the attached instruction manual... Figure 1-3As shown, the inner side of the horizontal rail 4, which is fixedly installed on the rear wall of the linkage plate 5, is slidably connected to the side wall of the connecting rod 3. The bottom of the connecting rod 3 is fixedly connected to the slider 201. Furthermore, the bottom of the slider 201 is slidably connected to the inner side of the slide rail 2. Thus, the above structure forms a linkage. By utilizing the sliding connection between the slider 201 and the slide rail 2, the linkage plate 5 can only convert the circular motion of the double-headed screw 6 into linear motion. At this time, the two linkage plates 5 begin to move closer to each other. As the two linkage plates 5 move closer to each other, the connecting rod 3 on the rear wall of the linkage plate 5 is also driven to move longitudinally on the top surface of the processing table 1. However, because the bottom slider 201 of the connecting rod 3 is in an "X" shape... The four slide rails 2 are relatively convergent within each other. Therefore, while the connecting rod 3 is moving longitudinally, it is also moving laterally closer to each other inside the transverse rail 4. Finally, as the linkage plate 5 moves closer to each other, the four sliders 201 begin to converge along the trajectory of the four corners of the top surface of the machining table 1 to form a four-corner positioning clamp for the flange placed at the center of the top surface of the machining table 1. This not only enables centering but also four-point positioning, ensuring the stability of the clamping. At the same time, the sliders 201 converge and clamp from four angles respectively. Regardless of whether the flange diameter is large or small, it can be clamped. Therefore, the rotational force of the tool alone cannot cause the flange to shift position.

[0028] Furthermore, there are two double-ended screws 6, which are symmetrically arranged at both ends of the linkage plate 5. The double-ended portions of the double-ended screws 6 penetrate the linkage plate 5 and form a threaded connection with it. The drive structure includes worm gears 7 located at the rear end of the processing table 1 and fixedly connected to the tail end of the double-ended screws 6. The bottoms of the two worm gears 7 mesh with a worm 8. The front and rear threads of the worm 8 are opposite. The tail end of the worm 8 is fixedly connected to a reduction motor through a coupling to form a drive.

[0029] The geared motor in this application is model 4RK25GN-CT-4GN6K; voltage 220V; frequency 50Hz / 60Hz, which is an existing device that can be directly purchased on the market. Therefore, the installation and operation of the geared motor will not be described in detail in this application. Furthermore, the geared motor in this application is manually operated to start and stop, without relying on the microcontroller to set parameters. Furthermore, the geared motor in this application is also equipped with a dust cover. Since flange milling will produce debris, in order to avoid the debris damaging the geared motor, the dust cover is a commercially available accessory product, which is only used for dust prevention. This application is also an improvement on it, so it will not be described in detail.

[0030] Furthermore, the connecting rod 3 is relatively perpendicular to the top surface of the processing table 1, and the bottom of the connecting rod 3 is fixedly connected to the top surface of the slider 201 by welding or bolts.

[0031] By fixing the connecting rod 3 and the slider 201 together, when the linkage plate 5 drives the connecting rod 3, the slider 201 at its bottom can be driven together. Then, the slider 201 slides in the slide rail 2 and affects the connecting rod 3 in the opposite direction, causing it to move laterally.

[0032] Example 1

[0033] Furthermore, the positioning pad 202 is a block made of rubber, and the rear wall of the positioning pad 202 is fixedly connected to the front wall of the slider 201 by an interlocking method.

[0034] Place the flange to be processed at the center of the top surface of processing table 1, as per the instruction manual. Figure 1 As shown, a circular mark is set at the center of the top surface of the machining table 1. Precise alignment is not required to start the drive structure. This application requires a matching milling cutter for milling and drilling. Since the milling and drilling equipment package has not been improved, existing drilling equipment can be used. At the same time, the drilling equipment occupies a small size. The two linkage plates 5 are close to each other and will not affect the drilling. In this embodiment, the drive structure is started by a reduction motor, which directly drives the worm gear 8 to rotate, as shown in the attached manual. Figure 2 As shown, the worm 8 is also double-ended, so the two worm wheels 7 at the beginning and end of the worm 8 are driven to rotate together. At this time, as the worm wheels 7 rotate, they drive the double-ended screw 6 to start rotating, as shown in the instruction manual. Figure 1 As shown, two double-ended screws 6 are threadedly connected to both sides of the two linkage plates 5 respectively. The threads at both ends of the double-ended screws 6 are opposite. Therefore, when the double-ended screws 6 begin to rotate in the forward direction, the threads at both ends move relative to the threaded holes at the through-holes of the linkage plates 5. At this time, as shown in the attached instruction manual... Figure 1-3 As shown, the inner side of the horizontal rail 4 fixedly installed on the rear wall of the linkage plate 5 is slidably connected to the side wall of the connecting rod 3, and the bottom of the connecting rod 3 is fixedly connected to the slider 201. Furthermore, the bottom of the slider 201 is slidably connected to the inner side of the slide rail 2. Thus, the above structure forms a linkage. By utilizing the sliding connection between the slider 201 and the slide rail 2, the linkage plate 5 can only convert the circular motion of the double-headed screw 6 into linear motion. At this time, the two linkage plates 5 begin to move closer to each other. As the two linkage plates 5 move closer to each other, the connecting rod 3 on the rear wall of the linkage plate 5 is also driven to move longitudinally on the top surface of the processing table 1. However, since the bottom slider 201 of the connecting rod 3 is relatively converged within the four slide rails 2 in an "X" shape, the connecting rod 3 actually moves longitudinally while simultaneously... The slides move laterally closer to each other inside the horizontal rail 4. Finally, as the linkage plate 5 moves closer to each other, the four sliders 201 begin to converge along the trajectory of the four corners of the top surface of the machining table 1 to form a four-corner positioning clamp for the flange placed at the center of the top surface of the machining table 1. This not only centers the flange but also provides four-point positioning, ensuring the stability of the clamping. At the same time, the sliders 201 converge and clamp from four angles, so the rotational force of the tool alone cannot cause the flange to shift position. Furthermore, the positioning pad 202, made of a single piece of rubber on the front wall of the slider 201, flexibly contacts the side wall of the flange to be processed, not only fixing it but also using the elasticity of the rubber to absorb the vibration during the milling process and prevent it from shifting position.

[0035] Example 2

[0036] Furthermore, the positioning pad 202 is a rectangular body made of hard plastic, and the front wall of the positioning pad 202 is also provided with a notch 203, and a rubber post 204 is fixedly installed inside the notch 203.

[0037] Furthermore, the rubber pillars 204 are spaced apart inside the recess 203, and there are gaps between the multiple rubber pillars 204.

[0038] Place the flange to be processed at the center of the top surface of processing table 1, as per the instruction manual. Figure 1 As shown, a circular mark is set at the center of the top surface of the processing table 1. Precise alignment is not required to start the drive structure. In this embodiment, the drive structure is started by a reduction motor that directly drives the worm gear 8 to rotate, as shown in the attached instruction manual. Figure 2 As shown, the worm 8 is also double-ended, so the two worm wheels 7 at the beginning and end of the worm 8 are driven to rotate together. At this time, as the worm wheels 7 rotate, they drive the double-ended screw 6 to start rotating, as shown in the instruction manual. Figure 1 As shown, two double-ended screws 6 are threadedly connected to both sides of the two linkage plates 5 respectively. The threads at both ends of the double-ended screws 6 are opposite. Therefore, when the double-ended screws 6 begin to rotate in the forward direction, the threads at both ends move relative to the threaded holes at the through-holes of the linkage plates 5. At this time, as shown in the attached instruction manual... Figure 1-3As shown, the inner side of the horizontal rail 4, which is fixedly installed on the rear wall of the linkage plate 5, is slidably connected to the side wall of the connecting rod 3. The bottom of the connecting rod 3 is fixedly connected to the slider 201. Furthermore, the bottom of the slider 201 is slidably connected to the inner side of the slide rail 2. Thus, the above structure forms a linkage. By utilizing the sliding connection between the slider 201 and the slide rail 2, the linkage plate 5 can only convert the circular motion of the double-headed screw 6 into linear motion. At this time, the two linkage plates 5 begin to move closer to each other. As the two linkage plates 5 move closer to each other, the connecting rod 3 on the rear wall of the linkage plate 5 is also driven to move longitudinally on the top surface of the processing table 1. However, since the bottom slider 201 of the connecting rod 3 is relatively converged within the four slide rails 2 in an "X" shape, the connecting rod 3 actually moves laterally closer to each other while moving longitudinally. Finally, as the linkage plates 5 move closer to each other, the connecting rod 3 moves laterally within the horizontal rail 4. As the four sliders 201 converge along a trajectory centered at the four corners of the top surface of the machining table 1, they form a four-corner positioning clamp for the flange placed at the center of the top surface of the machining table 1. This not only ensures centering but also provides four-point positioning, guaranteeing clamping stability. Furthermore, since the sliders 201 converge and clamp from four angles, the rotational force of the cutting tool alone cannot cause the flange to shift position. Additionally, multiple individual rubber pillars 204 on the front wall of the sliders 201 flexibly contact the side wall of the flange to be processed, not only fixing it in place but also absorbing vibrations during milling using the elasticity of the rubber, preventing positional shifts. The multiple individual rubber pillars 204 are installed at intervals inside the recess 203, creating a staggered, uneven surface that increases the contact area when clamping the flange.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
