Description

Technical Field

[0001] This utility model relates to the field of flange clamping technology, and in particular to a clamping fixture for polishing flange forgings. Background Technology

[0002] Because flange forgings operate in diverse and often harsh environments, their surface quality is crucial. On the one hand, good surface quality helps ensure sealing performance. If the surface is rough, has pits or protrusions, it can easily lead to poor sealing after the gasket is installed, causing media leakage. This is an extremely serious safety hazard in industries such as petrochemicals where leakage is unacceptable. On the other hand, an aesthetically pleasing surface is also important for applications with appearance requirements (such as exposed pipe connection flanges in high-end buildings). Moreover, a smooth surface can reduce the adhesion of impurities during use, which is beneficial for later maintenance. Polishing is a key step in improving the surface quality of flange forgings. Polishing can effectively remove forging marks, oxide scale, burrs, etc., to achieve the required roughness and gloss standards.

[0003] Some clamping fixtures have a narrow adjustable clamping force range. When dealing with flanges with large thickness differences, they cannot provide a suitable clamping force. For example, if the clamping force is too large for a thinner flange, it is easy to deform the flange, affecting its dimensional accuracy and subsequent performance. If the clamping force is insufficient for a thicker flange, it cannot be firmly clamped, and the flange is prone to shaking and displacement during the polishing process, resulting in uneven polishing and reduced polishing quality.

[0004] Therefore, we provide a clamping fixture for polishing flange forgings to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping fixture for polishing flange forgings, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flange forging polishing and clamping fixture, comprising a supporting and fixed base and an adjustable rotating clamping mechanism, wherein the adjustable rotating clamping mechanism is provided on the upper side of the supporting and fixed base;

[0007] The adjustable rotating clamping mechanism includes a clamping limiting component, a movable support component, a fitting rotating component, and an adjusting fixing component. The clamping limiting component is fixedly connected to the upper side of the supporting fixing base. The movable support component is fixedly connected to the inner wall of the clamping limiting component. The fitting rotating component is fixedly connected to one side of the clamping limiting component, and the adjusting fixing component is fixedly connected to the other side of the clamping limiting component.

[0008] Preferably, the clamping and limiting assembly includes a limiting base and a ventilation slot, the upper side of the supporting and fixing base is fixedly connected to the limiting base, and the bottom of the limiting base is provided with a ventilation slot.

[0009] Preferably, the movable support assembly includes a fixed support plate, a collar, and a lubricating ball. The fixed support plate is fixedly connected to the inner wall of the limiting base, the collar is fixedly connected to the inner side of the fixed support plate, and the lubricating ball is rotatably connected to the inner side of the collar.

[0010] Preferably, the fitting rotation assembly includes a fixed bracket, a drive motor, a rotating shaft, and an anti-slip sleeve. The fixed bracket is fixedly connected to one side of the limiting base, and the drive motor is fixedly connected to one side of the fixed bracket. The drive motor passes through the fixed bracket and is fixedly connected to the rotating shaft on the inner side. The surface of the rotating shaft is fitted with an anti-slip sleeve.

[0011] Preferably, the adjusting and fixing assembly includes a fixed support, a telescopic slider, and a rubber rotating wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With the adjustable rotary clamping mechanism, during use, the adjusting and fixing component fixed to one side of the limiting base can adjust the height of the telescopic slider to control the clamping and holding of flanges of different thicknesses. The fitting and rotating component on the other side adjusts the height of the upper sleeve in the same way, so that the anti-slip leather on the surface of the rotating shaft fits into the polished surface of the flange. The rotating shaft is driven by the drive motor to rotate, thereby performing a rotary polishing operation on the flange clamped on the inner side. By setting the adjusting and fixing component and the fitting and rotating component on both sides of the limiting base, the flange can be clamped and fixed twice during use, preventing the flange from shifting during rotary polishing.

During the flange clamping and polishing process, the ventilation slot 212 at the bottom of the limiting base 211 will allow cold air to flow through the holes on the flange surface to the flange surface, thereby cleaning the debris generated during the polishing process and preventing the debris from adhering to the flange surface and affecting the polishing effect.

[0022] Furthermore, the movable support assembly 22 includes a fixed support plate 221, a collar 222, and a lubricating ball 223.
