Technical Field
[0001] This utility model relates to the field of abrasive wheel technology, specifically an abrasive wheel that facilitates the replacement of abrasive pads. Background Technology
[0002] Abrasive wheels play an important role in industrial production, mainly used for grinding and polishing workpieces. Currently, the hub and abrasive cloth of existing abrasive wheels are fixedly connected, forming a single unit. This means that existing abrasive wheels must be replaced as a whole when the abrasive cloth wears down to a certain extent. This method is costly, and the undamaged hub is also discarded, resulting in resource waste. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an abrasive wheel that facilitates the replacement of abrasive pads. This solves the problem mentioned in the background art, where the abrasive pads are replaced as a whole when they wear down to a certain extent. This method is costly and wastes resources because the undamaged wheel hub is also discarded.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an abrasive wheel that facilitates the replacement of abrasive pads, comprising a clamping structure, wherein clamping and limiting structures are installed on both sides of the clamping structure;
[0005] The clamping structure includes a hub body with a through hole, and an elastic recess is fixedly installed on the surface of the hub body, while a clamping rubber block is fixedly installed inside the elastic recess.
[0006] A piece of abrasive cloth is placed inside the elastic concave block and the clamping rubber block for clamping and limiting.
[0007] The clamping and limiting structure includes a pressure plate with a connection port and a connection hole through its surface.
[0008] By adopting the above technical solution, the connection port can be opened to achieve through installation.
[0009] Preferably, a locking recess is fixedly installed on the inner side of the pressure plate, and a bolt rod is fixedly installed on the lower inner side of another pressure plate. At the same time, the other pressure plate is fixedly installed by a nut through the bolt rod extending through the through hole and the connecting hole.
[0010] By adopting the above technical solution, the nut is used to adjust and lock the device.
[0011] Preferably, the elastic recesses are arranged in a ring array, and the elastic recesses are made of an elastic metal material.
[0012] By adopting the above technical solution, the elastic concave block can achieve both inner fixation and outer force wrapping and compression.
[0013] Preferably, the clamping rubber blocks are symmetrically arranged, and the clamping rubber blocks are arranged in a single set symmetrically inside a single elastic concave block.
[0014] By adopting the above technical solution, the clamping rubber block is used to achieve compression locking and limiting.
[0015] Preferably, the pressure plate is provided in one set, and the locking recesses provided on the inner side of the pressure plate are provided in the same number.
[0016] By adopting the above technical solution, the pressure plate is set to achieve both opening and inner fixation.
[0017] Preferably, there are 6 bolt rods, and the bolt rods are arranged symmetrically along the axis.
[0018] By adopting the above technical solution, the bolt rods are used to achieve through-installation connection.
[0019] Compared with the prior art, the beneficial effects of this utility model are: the abrasive wheel with easy replacement of abrasive pads,
[0020] (1) This case solves the problem of replacing abrasive cloths as a whole after they are worn to a certain extent by setting up a clamping structure. This is costly and wastes resources because undamaged wheel hubs are also discarded. When the abrasive cloth is unusable, the nut is loosened to loosen the clamping rubber block and the sides of the abrasive cloth, making it easy to quickly replace the abrasive cloth. When a single abrasive cloth breaks and affects its use, the broken abrasive cloth can also be quickly replaced.
[0021] (2) By setting the clamping limit structure, the problem of the sandpaper sheet being easily subjected to centrifugal force and flying off is solved. After the sandpaper sheet is initially clamped, the bolt rod extends through the through hole and the unloading hole to install and connect with the nut. When the nut is adjusted, the locking concave block wraps and squeezes the locking concave block and the clamping rubber block to limit the clamped sandpaper sheet. At the same time, by adjusting the tightness of the nut, sandpaper sheets of different thicknesses can be replaced for installation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 This utility model provides a technical solution: an abrasive wheel that facilitates the replacement of abrasive pads, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a clamping structure 1, which includes a hub body 101 with a through hole 105. Elastic recesses 102 are fixedly mounted on the surface of the hub body 101. The elastic recesses 102 are arranged in a circular array and are made of elastic metal. This circular array arrangement not only ensures the equidistant installation of the components but also enhances their aesthetic appeal. Furthermore, the use of elastic metal allows for the effective distribution of sandpaper sheets 104 of varying thicknesses between the elastic recesses 102 for initial clamping and positioning. Simultaneously, the elastic recesses 102... 02 An internally fixed clamping rubber block 103 is installed. The clamping rubber block 103 is symmetrically arranged, and a single set of clamping rubber blocks 103 is symmetrically arranged inside a single elastic recess 102. When the above-mentioned components are arranged in a symmetrical manner, the sandpaper sheet 104 placed inside the elastic recess 102 is effectively clamped and fixed on both sides. When the clamping rubber block 103 is symmetrically arranged in a single set inside a single elastic recess 102, it not only avoids the inserted sandpaper sheet 104 from easily becoming loose, but also facilitates the subsequent wrapping and clamping and fixing of the sandpaper sheet 104. The elastic recess 102 and the clamping rubber block 103 are filled with clamping and limiting sandpaper sheet 104.
[0030] like Figure 4 and Figure 5 As shown, clamping structure 1 is equipped with clamping and limiting structures 2 on both sides. The clamping and limiting structures 2 include a pressure plate 206 with a connecting port 201 and a connecting hole 202 through its surface. One set of pressure plate 206 is provided, and the same number of locking recesses 203 are provided on the inner side of the pressure plate 206. When the above components are provided in a set of two blocks, it not only reflects the inner fixed installation of the above components, but also reflects the wrapping of the above components on both sides of the wheel hub body 101. When the above components are provided in a set of two blocks, it also effectively reflects the practicality of the installation of the above components. Furthermore, when the same number of locking recesses 203 are provided on the inner side of the pressure plate 206, the locking recesses 203 are effectively used to wrap and adjust the locking and limiting of both ends of the elastic recess 102.
[0031] Furthermore, in the above scheme, a locking recess 203 is fixedly installed on the inner side of the pressure plate 206, and a bolt rod 204 is fixedly installed on the lower inner side of another pressure plate 206. There are 6 bolt rods 204, and the bolt rods 204 are arranged symmetrically along the axis. When there are 6 bolt rods, it not only reflects the synchronous force-bearing and through-connection of the components, but also reflects the through-thread locking adjustment and limiting of the components. When there are only 6 bolt rods, it reflects the axial and longitudinal axis symmetry of the components. At the same time, the other pressure plate 206 is fixedly installed by a nut 205 through the bolt rods 204 extending through the through hole 105 and the connecting hole 202.
[0032] In the above scheme, when the abrasive sheet 104 needs to be replaced, the operator can loosen the nut 205 and pull the pressure plate 206 to separate the locking block 203 from the elastic block 102, thereby quickly replacing a single broken or all of the abrasive sheet 104.
