Description
Technical Field
[0001] This utility model relates to the field of flange fixing platform technology, and in particular to a flange grinding fixing platform. Background Technology
[0002] A flange is typically a disc-shaped metal body with several holes around its perimeter for fixing and connecting to other things. Its production process mainly consists of steps such as blank forming, drilling and milling, and grinding. In the grinding step, the flange needs to be fixed on a rotating part to complete the grinding work.
[0003] Existing flange grinding and fixing tables typically involve mounting the base on a control lathe, placing the flange on the base so that it is positioned between three clamping blocks, and then rotating a rotating column on one side of the base using a specific tool. This rotating column causes the geared disc inside the base to rotate, which in turn causes the three clamping blocks to move in opposite directions, clamping the flange surface and thus fixing the flange in place.
[0004] However, since the size of the clamping block is fixed, the effective fixing range of the clamping block may be limited, which may result in the clamping block being unable to effectively fix flanges with larger outer diameters, affecting the clamping efficiency and clamping flexibility of the flanges. Utility Model Content
[0005] The technical problem this invention aims to solve is that the fixed size of the clamping block may result in a limited effective fixing range, making it impossible to effectively fix flanges with larger outer diameters, thus affecting the clamping efficiency and flexibility of the flanges.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a flange grinding fixing table, including a base, a rotating column is provided inside the base, three clamping blocks are provided on one side of the base, an extension device is provided on one side of each of the three clamping blocks, and an auxiliary device is provided on one side of each of the three clamping blocks. The extension device includes a sliding groove opened on one side of the clamping block, a first threaded hole is opened on one side of the clamping block, the inner wall of the first threaded hole is connected to the inner wall of the sliding groove, a sliding rod is slidably connected to the inner wall of the sliding groove, a plurality of circular holes are opened on one side of the sliding rod, a bolt is provided inside any of the circular holes, the surface of the bolt is threadedly connected to the inner wall of the first threaded hole, and a pressure plate is fixedly connected to one side of the sliding rod, the surface of the pressure plate is L-shaped.
[0007] The effect achieved by the above components is as follows: By setting up an extension device, when it is necessary to fix a flange with a large outer diameter, the pressure plate can be manually moved, causing the pressure plate to drive the slide rod to move left and right along the inside of the slide groove, so that the pressure plate moves away from the base. When the pressure plate moves to the appropriate position, the inner wall of the first threaded hole coincides with the inner wall of any circular hole. At this time, the bolt is turned into the first threaded hole and the circular hole to fix the position of the slide rod, thereby adjusting and fixing the pressure plate. The effective clamping range of the clamping blocks is increased by adjusting the position of the pressure plate. The flange is then placed on the three clamping blocks, so that the flange is located between multiple pressure plates. At this time, the rotating column is rotated by a specific tool, causing the rotating column to drive the gear plate inside the base to rotate. The gear plate inside the base drives the three clamping blocks to move closer to each other, and the three clamping blocks drive the three pressure plates to move closer to each other and clamp the surface of the flange, thereby fixing the large outer diameter flange. This reduces the situation where the effective fixing range of the clamping blocks is limited due to the fixed size of the clamping blocks, which makes it impossible for the clamping blocks to effectively fix flanges with large outer diameters, thus affecting the clamping efficiency of the flange. This improves the flexibility of fixing flanges of various sizes.
[0008] Preferably, a plurality of rubber strips are fixedly connected to one side of the pressure plate, and the plurality of rubber strips are arranged at equal intervals.
[0009] The effect achieved by the above components is that by setting the rubber strip, the rubber strip can increase the fit between the pressure plate and the flange surface, increase the friction between the pressure plate and the flange surface, and at the same time reduce the large wear caused to the flange surface when the pressure plate squeezes the flange surface.
[0010] Preferably, a reinforcing block is fixedly connected to the inner side of the pressure plate, and the surface of the reinforcing block is trapezoidal.
[0011] The effect achieved by the above components is that by setting up reinforcing blocks, the reinforcing blocks can provide auxiliary support to the inner side of the pressure plate, reducing the tilting of the pressure plate when it is pressed against the flange surface.
[0012] Preferably, a limiting block is fixedly connected to one side of the slide rod, a limiting groove is formed on the inner wall of the slide groove, and the surface of the limiting block is slidably connected to the inner wall of the limiting groove.
[0013] The effect achieved by the above components is that by setting the limiting groove and the limiting block, the limiting block can be located inside the limiting groove to assist in limiting the sliding rod, thereby reducing the wobbling of the sliding rod during use.
[0014] Preferably, the clamping block has a storage groove on the side near the first threaded hole, and the inner wall of the storage groove is larger than the nut position of the bolt.
[0015] The effect achieved by the above-mentioned components is as follows: by setting up a receiving groove, after the bolt is fully turned into the first threaded hole, the bolt nut can be fully stored in the receiving groove, which reduces the situation where the bolt nut is higher than the surface of the clamping block, affecting the normal operation of the clamping block or hindering the normal placement of the flange.
[0016] Preferably, the auxiliary device includes a T-shaped groove formed on one side of the clamping block, a T-shaped block slidably connected to the inner wall of the T-shaped groove, and a rubber pad fixedly connected to the side of the T-shaped block away from the clamping block.
[0017] The effect achieved by the above components is as follows: by setting the auxiliary device, the rubber pad is first moved manually, so that the rubber pad drives the T-block to move. When the T-block moves to the position where it is fully inserted into the T-slot, the rubber pad is fixed on one side of the clamping block, so that the rubber pad is located at the contact position between the clamping block and the flange and separates the two, thereby protecting the flange surface, reducing the wear on the flange surface when the clamping block clamps and fixes the flange surface, and improving the clamping efficiency and safety of the clamping block on the flange.
[0018] Preferably, the surface of the rubber pad has multiple grooves, which are arranged at equal intervals.
[0019] The effect achieved by the above components is that by setting grooves, the contact points between the rubber gasket and the flange surface can be increased, the friction between the rubber gasket surface and the flange surface can be increased, and the slippage of the flange can be reduced.
[0020] Preferably, the inner wall of the T-shaped block is provided with a second threaded hole, and a screw is threadedly connected to the inner wall of the second threaded hole. The inner wall of the T-shaped groove is provided with a circular groove, and the surface size and shape of the screw are adapted to the size and shape of the inner wall of the circular groove.
[0021] The effect achieved by the above components is that by setting the second threaded hole and screw, personnel can use tools to turn the screw into the position of the second threaded hole and the circular groove to fix the T-block inserted into the T-slot, reducing the possibility of the T-block sliding up and down during use.
[0022] The beneficial effects of this utility model are:
[0023] By setting an extension device, the effective clamping range of the clamping block can be increased, reducing the situation where the effective fixing range of the clamping block is limited due to the fixed size of the clamping block, which makes it impossible to effectively fix flanges with larger outer diameters and affects the clamping efficiency of the flanges. This improves the flexibility of fixing flanges of various sizes. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. 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.
[0033] Example 1, Figure 1-5 The flange grinding and fixing table shown includes a base 1, a rotating column 2 is provided inside the base 1, three clamping blocks 3 are provided on one side of the base 1, an extension device 4 is provided on one side of each of the three clamping blocks 3, and an auxiliary device 5 is provided on one side of each of the three clamping blocks 3.
[0034] Figure 2 and Figure 3The extension device 4 shown includes a groove 41 formed on one side of the clamping block 3. A first threaded hole 42 is formed on one side of the clamping block 3. The inner wall of the first threaded hole 42 is connected to the inner wall of the groove 41. A slide rod 45 is slidably connected to the inner wall of the groove 41. A plurality of circular holes 46 are formed on one side of the slide rod 45. A bolt 47 is installed inside any circular hole 46. The surface of the bolt 47 is threaded to the inner wall of the first threaded hole 42. A pressure plate 48 is fixedly connected to one side of the slide rod 45. The surface of the pressure plate 48 is L-shaped. By setting the extension device 4, when it is necessary to fix a flange with a large outer diameter, the pressure plate 48 is manually moved, so that the pressure plate 48 drives the slide rod 45 to move left and right along the inside of the groove 41, so that the pressure plate 48 moves away from the base 1. When the pressure plate 48 moves to the appropriate position, the inner wall of the first threaded hole 42 coincides with the inner wall of any circular hole 46. At this time, a tool is used to... Bolt 47 is screwed into the first threaded hole 42 and the circular hole 46 to fix the position of the slide rod 45, thereby adjusting and fixing the pressure plate 48. This allows the effective clamping range of the clamping block 3 to be increased by adjusting the position of the pressure plate 48. At this time, the flange is placed on the three clamping blocks 3, so that the flange is located between the multiple pressure plates 48. Then, the rotating column 2 is rotated by a specific tool, which causes the rotating column 2 to drive the gear plate inside the base 1 to rotate. This causes the gear plate inside the base 1 to drive the three clamping blocks 3 to move closer to each other, and the three clamping blocks 3 drive the three pressure plates 48 to move closer to each other and clamp the surface of the flange. This achieves the fixation of large outer diameter flanges, reducing the situation where the effective fixing range of the clamping block 3 is limited due to the fixed size of the clamping block 3, which makes it impossible for the clamping block 3 to effectively fix flanges with large outer diameters, thus affecting the clamping efficiency of the flange. This improves the flexibility of fixing flanges of various sizes.
[0035] Figure 2 and Figure 3 Multiple rubber strips 49 are fixedly connected to one side of the pressure plate 48 shown. The multiple rubber strips 49 are arranged at equal intervals. By setting the rubber strips 49, the rubber strips 49 can increase the fit between the pressure plate 48 and the flange surface, increase the friction between the pressure plate 48 and the flange surface, and at the same time reduce the large wear caused to the flange surface when the pressure plate 48 is pressed. A reinforcing block 410 is fixedly connected to the inner side of the pressure plate 48. The surface of the reinforcing block 410 is trapezoidal. By setting the reinforcing block 410, the reinforcing block 410 can provide auxiliary support to the inner side of the pressure plate 48 and reduce the tilting of the pressure plate 48 when it is pressed against the flange surface.
[0036] Figure 2 and Figure 3A limiting block 411 is fixedly connected to one side of the slide rod 45. A limiting groove 44 is opened on the inner wall of the slide groove 41. The surface of the limiting block 411 is slidably connected to the inner wall of the limiting groove 44. By setting the limiting groove 44 and the limiting block 411, the limiting block 411 can be located inside the limiting groove 44 to assist in limiting the slide rod 45, reducing the wobbling of the slide rod 45 during use. A receiving groove 43 is opened on the side of the clamping block 3 near the first threaded hole 42. The inner wall of the receiving groove 43 is larger than the nut position of the bolt 47. By setting the receiving groove 43, after the bolt 47 is completely turned into the first threaded hole 42, the nut position of the bolt 47 can be completely stored inside the receiving groove 43, reducing the situation where the nut position of the bolt 47 is higher than the surface of the clamping block 3, affecting the normal operation of the clamping block 3 or hindering the normal placement of the flange.
[0037] Figure 4 and Figure 5 The auxiliary device 5 shown includes a T-slot 51 formed on one side of the clamping block 3. A T-block 53 is slidably connected to the inner wall of the T-slot 51. A rubber pad 54 is fixedly connected to the side of the T-block 53 away from the clamping block 3. By setting the auxiliary device 5, the rubber pad 54 is first manually moved, causing the rubber pad 54 to drive the T-block 53 to move. When the T-block 53 moves to the position where it is fully inserted into the T-slot 51, the rubber pad 54 is fixed on one side of the clamping block 3. This positions the rubber pad 54 at the contact position between the clamping block 3 and the flange, separating the two and protecting the flange surface. This reduces the wear on the flange surface when the clamping block 3 clamps and fixes it, and improves the clamping efficiency and safety of the clamping block 3 on the flange.
[0038] Figure 4 and Figure 5 The rubber pad 54 shown has multiple grooves 55 on its surface, which are arranged at equal intervals. By setting the grooves 55, the contact points between the rubber pad 54 and the flange surface are increased, thereby increasing the friction between the rubber pad 54 and the flange surface and reducing the possibility of the flange sliding. The inner wall of the T-block 53 has a second threaded hole 56, and a screw 57 is threaded into the inner wall of the second threaded hole 56. The inner wall of the T-slot 51 has a circular groove 52. The size and shape of the screw 57 are adapted to the size and shape of the inner wall of the circular groove 52. By setting the second threaded hole 56 and the screw 57, personnel can use tools to turn the screw 57 into the position of the second threaded hole 56 and the circular groove 52 to fix the T-block 53 inserted into the T-slot 51, thereby reducing the possibility of the T-block 53 sliding up and down during use.
[0039] Working principle: When it is necessary to fix a flange with a large outer diameter, manually move the pressure plate 48, so that the pressure plate 48 drives the slide rod 45 to move left and right along the inside of the slide groove 41, so that the pressure plate 48 moves away from the base 1. When the pressure plate 48 moves to the appropriate position, the inner wall of the first threaded hole 42 coincides with the inner wall of any circular hole 46. At this time, the bolt 47 is turned into the first threaded hole 42 and the circular hole 46 to fix the position of the slide rod 45, thereby adjusting and fixing the pressure plate 48. The effective clamping range of the clamping block 3 is increased by adjusting the position of the pressure plate 48. Then, the flange is placed on the three clamping blocks 3, so that the flange is located between multiple pressure plates 48. At this time, the rotating column 2 is rotated by a specific tool, so that the rotating column 2 drives the gear plate inside the base 1 to rotate, so that the gear plate inside the base 1 drives the three clamping blocks 3 to move closer to each other, so that the three clamping blocks 3 drive the three pressure plates 48 to move closer to each other and clamp the surface of the flange, thereby fixing the large outer diameter flange.
[0040] First, manually move the rubber pad 54 so that it moves the T-block 53. When the T-block 53 moves to the position where it is fully inserted into the T-slot 51, the inner wall of the second threaded hole 56 coincides with the inner wall of the circular groove 52. At this time, use a tool to turn the screw 57 into the position of the second threaded hole 56 and the circular groove 52 to fix the T-block 53 in place, so that the rubber pad 54 is fixed on one side of the clamping block 3. This makes the rubber pad 54 located at the contact position between the clamping block 3 and the flange and separate the two, thereby protecting the flange surface.
[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
