Description

Technical Field

[0001] The utility model relates to the technical field of flange positioning, in particular to a positioning mechanism for flange production and processing. Background Technique

[0002] A flange is also called a flange or a collar, which is a part for connecting pipes to each other. It is connected to the pipe end. There are holes on the flange, and bolts are used to tightly connect the two flanges. A gasket is used for sealing between the flanges. A flange is a disc-shaped part and is most common in pipeline engineering. Flanges are always used in pairs. In pipeline engineering, flanges are mainly used for pipeline connection. At the ends of two pipelines that need to be connected, a flange disc is installed on each end. When processing a flange, it is necessary to first fix the flange through a positioning mechanism.

[0003] The published patent No. CN219747719U discloses a positioning tooling for a flange of a vehicle rear axle housing, including a bottom plate, a base plate and a positioning plate. The bottom plate is rotatably installed with a base plate through a rotating shaft, a rotating mechanism is installed between the base plate and the bottom plate, the base plate is fixedly connected with a positioning plate through a support block, adjustment grooves are uniformly opened on the surface of the positioning plate, and a middle groove penetrates through the middle of the lower surface of the inner cavity of the adjustment groove. A positioning mechanism is installed in the middle groove. Although this kind of positioning tooling can drive the positioning plate to rotate through the rotating mechanism via the base plate and the support block, and then drive the flange of the vehicle rear axle housing fixed on the surface of the positioning plate to rotate, thus completing the processing assistance work of the positioning tooling for the flange of the vehicle rear axle housing. However, in the prior art, the centering operation of the flange usually depends on manual adjustment and visual inspection. This not only requires operators to have high operation skills and experience, but also is prone to inaccurate positioning of the flange due to the influence of human factors, resulting in offset errors during the processing. Therefore, improvements are needed. Content of the Utility Model

A sliding plate is slidably connected to the inner wall of the vertical groove. A top block is fixedly installed on the top surface of the sliding plate. An extrusion block is fixedly installed on the side surface of the short block. A slope is provided on the side surface of the extrusion block. Here, it is convenient to take out the flange.

[0011] Preferably, the extrusion block is made of austenitic stainless steel.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. The present utility model drives the short block to slide in the central groove through the bidirectional lead screw, and then drives the fixing rod to move.

At the same time, the fixing rod and the short block not only play a role in centering and clamping, but also can assist in lifting and taking out the flange. This multi-functional design makes the present utility model more compact, reduces additional operation steps and mechanical components, and improves practicability and economy.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a positioning mechanism for flange production and processing, including a processing table 1. The top surface of the processing table 1 is rotatably connected with a driven gear 2. The driven gear 2 is fixed on the processing table 1 through a bearing mounting seat. This connection method can ensure the stability and low friction of the driven gear 2 during rotation, thereby improving the overall transmission efficiency of the equipment. The top end of the driven gear 2 is fixedly installed with a substrate 3. The substrate 3 is connected to the driven gear 2 by a bolt fixing method. The bolt fixing method not only ensures the firm installation of the substrate 3 but also facilitates later disassembly and maintenance. The material of the substrate 3 can be selected from high-strength aluminum alloy or steel to improve its durability and anti-deformation ability. The bottom surface of the processing table 1 is fixedly installed with a motor 4. The motor 4 is connected to the processing table 1 through a flange. The flange connection method can provide high-precision installation and strong mechanical strength, ensuring the stable operation of the motor 4 under high load. The output end of the motor 4 is installed with a driving gear 5. The driving gear 5 is installed on the output shaft of the motor 4 by a key connection method. This connection method can ensure the efficient transmission between the driving gear 5 and the output shaft of the motor 4 and avoid the occurrence of slipping. The driving gear 5 meshes with the driven gear 2, and the meshing accuracy between the two is achieved by adjusting the gear clearance, ensuring the efficient and stable operation of the transmission system. The bottom surface of the processing table 1 is fixedly installed with support legs. The support legs are connected to the bottom surface of the processing table 1 by welding. The welding connection can provide strong support force and stability, ensuring that the processing table 1 does not vibrate and displace during operation.

[0026] Please refer to Figures 1-5The top surface of the substrate 3 is provided with a top groove 6, and the inner wall of the top groove 6 is slidably connected to the slider 8 through a precision guide rail. The use of the guide rail can provide a smooth sliding path for the slider 8, avoid the occurrence of jamming, and ensure that the slider 8 can be accurately positioned during the positioning process. The inside of the slider 8 is provided with a thread, and the thread is meshed with the threaded rod 7. The threaded connection method ensures that the slider 8 can accurately move forward and backward under the drive of the threaded rod 7. A clamping block 9 is fixedly installed on the top surface of the slider 8, and the clamping block 9 can be connected to the slider 8 by bolts, which is convenient for later disassembly and replacement. The clamping block 9 is used to clamp the flange to ensure that the flange does not move during the processing process. The top surface of the substrate 3 is provided with a center groove 10, and the inner wall of the center groove 10 is slidably connected to the short block 12 through a ball guide rail. The use of the ball guide rail can provide a low-friction and high-precision sliding path, ensuring that the short block 12 can be accurately centered in the center groove 10. A fixing rod 13 is fixedly installed on the top of the short block 12, and the fixing rod 13 is connected to the short block 12 by a threaded connection. Such a connection method can not only ensure the stability of the fixing rod 13, but also facilitate the adjustment of the length of the fixing rod 13 to adapt to flanges of different specifications. A left-handed thread is provided on one side of the surface of the bidirectional screw rod 11, and a right-handed thread is provided on the other side. The bidirectional screw rod 11 is connected to the inner wall of the center groove 10 by a threaded connection. Such a design can ensure that the bidirectional screw rod 11 can drive the two groups of short blocks 12 to move away from or towards each other when rotating, and then drive the fixing rod 13 to tighten or loosen the flange in the inner hole of the flange, so as to realize the centering and release of the flange.

[0027] Embodiment 2

[0028] See also Figures 4-5 The top surface of the base plate 3 is provided with a lifting mechanism, which includes a vertical groove 14. The inner wall of the vertical groove 14 is slidably connected to the slide plate 15 through a slide rail. The use of the slide rail ensures the stability and accuracy of the slide plate 15 when it moves up and down. A top block 16 is fixedly installed on the top surface of the slide plate 15. The top block 16 is used to lift the flange to facilitate the removal of the workpiece. An extrusion block 17 is fixedly installed on the side of the short block 12. The extrusion block 17 is fixed to the side of the short block 12 with bolts to ensure the stability and durability of the extrusion block 17 when it is subjected to force. A slope 18 is provided on the side of the extrusion block 17. The slope 18 is designed as an inclined surface, which can lift the top block 16 during the extrusion process to achieve the lifting function of the flange.

[0029] Working principle: When it is necessary to position the flange, just place the flange on the base plate 3, and then turn the threaded rod 7 to make the clamping block 9 clamp the flange. At this time, the flange can be positioned. At the same time, for centering, the staff can first turn the bidirectional lead screw 11. Since the thread directions at both ends of the bidirectional lead screw 11 are opposite, the bidirectional lead screw 11 can drive the two groups of short blocks 12 to move away from each other at this time. The short blocks 12 slide in the central groove 10 at this time, and then the short blocks 12 can drive the fixed rod 13 to move. During the movement of the fixed rod 13 at this time, the inner hole of the flange can be tensioned. During the tensioning process of the fixed rod 13, the flange can be centered naturally. After centering like this, it is clamped by the clamping block 9. The utility model drives the short block 12 to slide in the central groove 10 through the bidirectional lead screw 11, and then drives the fixed rod 13 to move. During the tensioning process of the fixed rod 13 in the inner hole of the flange, the flange can be centered naturally, ensuring that the flange always remains in the central position during positioning, avoiding the processing error caused by deviation. At the same time, the centering operation steps are simplified, the human error during centering is reduced, and the work efficiency is improved. After clamping the flange, the motor 4 can be used to drive the driving gear 5 to rotate. The driving gear 5 can then drive the driven gear 2 engaged with it to rotate. The driven gear 2 can then drive the base plate 3 to rotate. At this time, the flange can be rotated, so as to process the flange. At the same time, after the flange processing is completed, the staff can turn the bidirectional lead screw 11 in the reverse direction to make the short blocks 12 move towards each other, so that the fixed rod 13 no longer presses the inner hole of the flange. At the same time, if the short blocks 12 continue to move towards each other, the short blocks 12 can drive the extrusion block 17 to extrude the top block 16. The side of the extrusion block 17 is a slope 18 structure. During the extrusion process of the slope 18, the top block 16 can be made to move upward. When the top block 16 moves upward, it can lift the flange. Specifically, the fixed rod 13 and the short block 12 can not only center the flange, but also lift the flange, so as to facilitate taking out the flange. After the processing of the utility model is completed, operating the bidirectional lead screw 11 in the reverse direction can not only relieve the extrusion of the fixed rod 13 on the inner hole of the flange, but also use the slope 18 structure of the short block 12 and the extrusion block 17 to lift the flange, simplifying the operation steps of taking out the flange, avoiding scratches or damage that may be caused when taking out the flange manually, and improving the convenience and safety of the operation. At the same time, the fixed rod 13 and the short block 12 not only play a role in centering and clamping, but also can assist in lifting and taking out the flange. This multi-functional design makes the utility model more compact, reduces additional operation steps and mechanical components, and improves the practicability and economy.
