Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric testing equipment, and in particular to a grinding table cover for a flat grinder. Background Technology
[0002] It is used to determine the pilling degree of various fabrics under slight pressure and the abrasion resistance of thin cotton, linen and silk woven fabrics.
[0003] During testing, the felt is first fixed on the grinding table of the surface grinder, and then the fabric sample is fixed on the upper grinding disc of the surface grinder. Pressure is applied to the sample to create pressure between the sample and the felt. The upper template moves the sample relative to the felt, causing friction between the two. The surface grinder measures the abrasion resistance of the fabric. Usually, the pressure cap and the grinding table are connected by threads. When fixing the felt, the felt is first placed on the grinding table, and then the pressure cap is put on the grinding table, pressing the felt down. Tightening the pressure cap will press the felt tightly onto the grinding table. To increase the accuracy of the test results, multiple samples are taken for testing. Therefore, when fixing each sample on the grinding table of the surface grinder, it is necessary to tighten the pressure cap of the grinding table. This is cumbersome when there are many samples. Utility Model Content
[0004] The purpose of this utility model is to provide a grinding table cover for a surface grinder, which has the advantage of being easy to install or remove from the grinding table.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A grinding table cover for a surface grinder is provided, wherein the surface grinder includes a grinding table, characterized in that the cover includes an end cap, the end cap is placed on the grinding table, an outer edge is fixedly connected to the outer walls of the upper and lower openings of the end cap, a sleeve is provided at the lower opening of the end cap, a sleeve is fitted over the end cap, the sleeve is slidably connected to the end cap, the sleeve is located inside the sleeve, and a hinge is hinged between the end face of the sleeve and the end cap, the hinge is composed of two connecting rods with hinged ends, and the two ends of the hinge are respectively hinged to the outer edge of the sleeve and the end cap.
[0006] Using the above technical solution, the felt is placed on the end face of the grinding table, and the pressure cap is placed over the grinding table. The grinding table passes through the end cap of the pressure cap and the inside of the clamp. The upper end face of the end cap presses against the felt, and the inner wall of the clamp contacts the outer wall of the grinding table. Then, the sleeve is moved downwards. The lower opening edge of the sleeve exerts a force on the outer wall of the clamp, causing the clamp to deform and contract to clamp the grinding table. At the same time, the moving sleeve causes the hinge to extend, so that the two connecting rods of the hinge are on the same straight line, thus creating a dead point. The hinge abuts against the sleeve, preventing the force between the clamp and the sleeve from causing the sleeve to move back, thereby fixing the pressure cap. On the grinding table, the pressure cap presses the felt firmly against the table to prevent the felt from loosening due to friction between the sample and the felt during testing, which would affect the test. When removing the sample from the grinding table, the connecting rod hinged to the end cap on the hinge is rotated. The rotating rod drives the sleeve to rise through another connecting rod hinged to it. The inner wall of the sleeve separates from the jacket, and the jacket expands outward, separating its inner wall from the outer wall of the grinding table. This allows the jacket to be removed from the grinding table, and then the sample can be removed. Simply moving the sleeve downwards can fix the pressure cap to the grinding table, making disassembly and assembly convenient and increasing work efficiency.
[0007] Preferably, the inner wall of the sleeve is provided with a wedge-shaped surface, and the wedge-shaped surface of the inner wall of the sleeve contacts the outer wall of the jacket.
[0008] By adopting the above technical solution, the contact area between the sleeve and the jacket is increased, thereby making the inner wall of the sleeve press the jacket more stably.
[0009] Preferably, a guide post is fixedly connected between the outer edges of the upper and lower ends of the end cap, the guide post passes through the end face of the sleeve, and the guide post and the sleeve are slidably connected.
[0010] Using the above technical solution, the guide post is used to guide and restrict the movement of the sleeve, thereby increasing the stability of the guide post's movement.
[0011] Preferably, a rubber pad is attached to the inner wall of the jacket.
[0012] By adopting the above technical solution, the friction between the jacket and the grinding table is increased, making the connection between the gland and the grinding table tighter.
[0013] Preferably, the outer wall of the sleeve is provided with friction texture.
[0014] By adopting the above technical solution, the friction between the sleeve and the hand is increased, resulting in better sleeve movement. Attached Figure Description

[0017] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
[0018] See Figures 1 to 5 A grinding table cover for a surface grinder is provided. The surface grinder includes a grinding table 1, and the cover includes an end cap 2, which is placed on the grinding table 1. An outer edge 3 is fixedly connected to the outer walls of the upper and lower openings of the end cap 2. A sleeve 4 is provided at the lower opening of the end cap 2, and a rubber pad is adhered to the inner wall of the sleeve 4 to increase friction between the sleeve 4 and the grinding table 1. A sleeve 5 is fitted over the end cap 2, and friction texture is provided on the outer wall of the sleeve 5 to increase friction between the sleeve 5 and the hand, facilitating better movement of the sleeve 5. The sleeve 5 is slidably connected to the end cap 2, and a wedge-shaped surface 7 is provided on the inner wall of the sleeve 5. The sleeve 4 is located inside the sleeve 5, and the wedge-shaped surface 7 of the inner wall of the sleeve 5 contacts the outer wall of the sleeve 4. A hinge 6 is hinged between the end face of the sleeve 5 and the end cap 2. The hinge 6 consists of two connecting rods hinged at their ends, with both ends of the hinge 6 hinged to the sleeve 5 and the outer edge 3 of the end cap 2, respectively. A guide post 8 is fixedly connected between the outer edges 3 of the upper and lower ends of the end cap 2. The guide post 8 passes through the end face of the sleeve 5 and is slidably connected to the sleeve 5. The guide post 8 is used to guide and restrict the movement of the sleeve 5 and increase the stability of the movement of the guide post 8.
[0019] Working principle: The felt is placed on the end face of the grinding table 1, and the pressure cap is placed over the grinding table 1. The grinding table 1 is inserted into the end cap 2 and the clamp 4 of the pressure cap. The upper end face of the end cap 2 presses down on the felt, and the inner wall of the clamp 4 contacts the outer wall of the grinding table 1. Then, the sleeve 5 is moved downward. The lower opening edge of the sleeve 5 exerts a force on the outer wall of the clamp 4, causing the clamp 4 to deform and contract to clamp the grinding table 1. At the same time, the moving sleeve 5 drives the hinge 6 to extend, so that the two connecting rods of the hinge 6 are on the same straight line, thus creating a dead point. The hinge 6 abuts against the sleeve 5, preventing the force between the clamp 4 and the sleeve 5 from causing the sleeve 5 to move back, thereby fixing the pressure cap on the grinding table 1. The pressure cap presses the felt tightly onto the grinding table 1, preventing the friction between the sample and the felt from loosening during sample testing, which would affect the test. When removing the sample from the grinding table 1, rotate the connecting rod that is hinged to the end cap 2 on the hinge 6. The rotating rod drives the sleeve 5 to rise through another connecting rod that is hinged to it. The inner wall of the sleeve 5 separates from the jacket 4, and the jacket 4 expands outward, separating its inner wall from the outer wall of the grinding table 1. Thus, the jacket 4 can be removed from the grinding table 1, and then the sample can be removed. Simply move the sleeve 5 downward to fix the cap to the grinding table 1. This makes disassembly and assembly convenient and increases work efficiency.
