[0002] Tooling, or process equipment, refers to the general term for various tools used in the manufacturing process, including cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, pliers tools and work station equipment.

[0003] Flange is a general term for flange. It usually refers to a disk-like metal body with several fixing holes opened around it for connecting other things. It is widely used in machinery. For some high-precision flanges, it is usually necessary to grind the flanges during production. When grinding the flanges, it is usually necessary to limit the flanges. When grinding the flanges, it is usually necessary to turn the flanges over. Some existing tooling is usually not easy to apply force to the flanges after limiting the flanges, making the turning over process of the flanges more inconvenient. Therefore, a structure is provided to solve the problem that some existing flange tooling is not easy to turn over the flanges during use.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a position limiting tool for grinding a flange.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: the limiting tooling for flange grinding comprises a base, a supporting surface is horizontally provided on the base, a limiting plate which slides vertically is provided on the base, a limiting groove which is vertically penetrated on the limiting plate and is sleeved on the outside of the supporting surface, the top opening of the limiting groove can slide vertically to be lower than the supporting surface, the bottom opening of the limiting groove is lower than the supporting surface, and the top opening of the limiting groove is higher than the supporting surface.

[0007] The utility model is further configured as follows: a force for pushing the limiting plate to slide until the top opening of the limiting groove is higher than the supporting surface is provided between the limiting plate and the base.

[0008] The utility model is further configured as follows: a plurality of elastic members distributed circumferentially and fixedly connected to the base are fixedly connected to the bottom of the limit plate.

[0009] The utility model is further configured as follows: the top surface of the base is fixedly connected with a support platform, the support surface is located on the top surface of the support platform, a clearance cavity for the limit plate to slide is surrounded between the support platform and the base, and the elastic member is fixedly connected to the inner bottom surface of the clearance cavity.

[0010] The utility model is further configured as follows: a plurality of guide rods distributed circumferentially and located on the inner side of the elastic member are fixedly connected to the inner bottom surface of the give way cavity, a limiting block is fixedly connected to the top of the guide rod, and a countersunk hole which is sleeved on the guide rod and for the limiting block to be embedded is provided on the limiting plate.

[0011] The utility model is further configured as follows: the support platform is provided with a plurality of force-applying grooves distributed in the circumferential direction, and the force-applying grooves located at the peripheral wall of the support platform are arranged through.

[0012] The utility model is further configured such that: the inner bottom surface of the force-applying groove is flush with the inner bottom surface of the clearance cavity.

[0013] In summary, the utility model has the following beneficial effects:

[0014] When the top opening of the limit groove moves below the supporting surface, the limit groove loses the freedom of sliding of the flange in the horizontal direction, so that the user can push the flange away from the supporting surface and use the gap between the top surface of the limit plate and the supporting surface to better apply force to the flange, making it more convenient for the user to turn over the flange. The bottom opening of the limit groove is lower than the supporting surface. This setting ensures that the limit groove can be stably mounted on the outside of the supporting surface and slide along the outside of the supporting surface. The top opening of the limit groove is higher than the supporting surface. This setting ensures that the groove wall of the limit groove can be against the side wall of the flange, so that the limit plate and the supporting surface can achieve stable limiting of the flange.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The flange grinding limit fixture, such as Figure 1As shown, it includes a base 1, and the base 1 is used to achieve stable support and limiting effects on various parts. A plurality of circumferentially distributed mounting holes are provided on the base 1. With the help of the mounting holes and bolts, the base 1 can be stably fixed to the workbench to ensure that the state of the entire structure during processing remains stable. A supporting surface 2 is horizontally provided on the base 1, and a limiting plate 3 that slides vertically is provided on the base 1. A limiting groove 4 that is sleeved on the outer side of the supporting surface 2 is vertically penetrated on the limiting plate 3. The top opening of the limiting groove 4 can slide vertically to below the supporting surface 2. When the top opening of the limiting groove 4 moves to below the supporting surface 2, the limiting groove 4 is The freedom of sliding of the flange in the horizontal direction will be lost due to the positioning groove 4, so that the user can push the flange away from the supporting surface 2 and use the gap between the top surface of the limiting plate 3 and the supporting surface 2 to better apply force to the flange, making it more convenient for the user to turn over the flange. The bottom opening of the limiting groove 4 is lower than the supporting surface 2. This setting ensures that the limiting groove 4 can be stably mounted on the outside of the supporting surface 2 and slide along the outside of the supporting surface 2. The top opening of the limiting groove 4 is higher than the supporting surface 2. This setting ensures that the groove wall of the limiting groove 4 can be against the side wall of the flange, so that the limiting plate 3 and the supporting surface 2 can achieve stable limiting of the flange.

[0021] like Figure 2 and Figure 3 As shown, a force is provided between the limit plate 3 and the base 1 for pushing the limit plate 3 to slide until the top opening of the limit groove 4 is higher than the support surface 2. The bottom of the limit plate 3 is fixedly connected with a plurality of elastic members 5 distributed circumferentially and fixedly connected to the base 1. The elastic members 5 are arranged as springs. With the help of the good elastic deformation performance of the springs, it is ensured that the elastic members 5 can stably push the limit plate 3 to slide upward and perform stably reset, so that the opening at the top of the limit groove 4 remains higher than the support surface 2 when not subjected to external force, thereby ensuring that the groove wall of the limit groove 4 can be against the side wall of the flange placed on the support surface 2, thereby achieving stable limiting of the flange, and ensuring that the limiting function that the limit plate 3 can achieve is more stable.

[0022] like Figure 2 and Figure 3The support plate 6 is provided with a plurality of support members 4, each of which is provided with a plurality of support members 4, and the plurality of support members 4 are provided with plurality of support members 4.

[0023] like Figure 2 and Figure 3 As shown, a plurality of guide rods 8 which are circumferentially distributed and located on the inner side of the elastic member 5 are fixedly connected to the inner bottom surface of the yield cavity 7 by welding, and a limiting block 9 is fixedly connected to the top of the guide rod 8 by welding. A countersunk hole 10 which is sleeved on the guide rod 8 and for the limiting block 9 to be embedded is provided on the limiting plate 3. The limiting block 9 is used to achieve stable restriction of the upward sliding path of the limiting plate 3 to prevent the limiting plate 3 from slipping off the guide rod 8. At the same time, with the help of the joint action of the guide rod 8 and the countersunk hole 10, it is ensured that the guide rod 8 can achieve stable guiding and limiting effect on the sliding process of the limiting plate 3, ensuring that the path of the limiting sliding and the sliding process are smoother, making the use of the overall structure more stable.

[0024] like Figure 2 and Figure 3 As shown, a plurality of force-applying grooves 11 distributed circumferentially are provided on the support platform 6, and the top openings of the force-applying grooves 11 are flush with the top surface of the support platform 6, and the force-applying grooves 11 located at the peripheral walls of the support platform 6 are arranged through, and the inner bottom surface of the force-applying grooves 11 is flush with the inner bottom surface of the yield cavity 7. With the help of the arranged force-applying grooves 11, when the user pushes the limit plate 3 to slide downward, the openings of the force-applying grooves 11 located at the peripheral walls of the support platform 6 will be exposed, so that the user can use the force-applying grooves 11 to apply force to the bottom surface of the flange, and thus the flange can be better taken out of the limit groove 4 and turned over or replaced. The force-applying grooves 11 are arranged to have an inner bottom surface flush with the inner bottom surface of the yield cavity 7, and this arrangement ensures that the opening of the force-applying grooves 11 is more fully opened, so that the user can better apply force to the flange with the help of the force-applying grooves 11.

[0025] When the flange is polished, the bottom surface of the flange 4 abuts against the support surface 2 of the support platform 6, and the side wall of the flange abuts against the groove wall of the limiting groove 4. After the end face of one side of the flange is polished, a downward force is applied to the limiting plate 3. During the process, the limiting plate 3 slides downward and the elastic member 5 is squeezed and deformed. During the process, the top opening of the limiting groove 4 gradually slides to below the support surface 2. At this time, the force groove 11 is gradually exposed. After the user contacts the force groove 11 to apply force to the flange, the force applied to the limiting plate 3 is cancelled. Under the action of the elastic force generated by the elastically deformed elastic member 5, the limiting plate 3 is pushed to gradually slide and reset, so that the limiting function of the limiting groove 4 for the flange is gradually reset, and the flange after turning over can continue to be placed in the limiting groove 4 for subsequent polishing. The above is the working principle of the utility model.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
