Technical Field

[0001] The present application relates to the technical field of cylindrical grinders, and in particular to a floating oil seal cylindrical grinder. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as high-power grinding.

[0023] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0024] The present application embodiment discloses a floating oil seal cylindrical grinding machine. Figure 1-Figure 3 A floating oil seal external cylindrical grinder comprises an external cylindrical grinder body 1, the external cylindrical grinder body 1 is slidably connected to a tailstock 2 and a headstock 3 through guide rails, the front side of the external cylindrical grinder body 1 is located above a control box and is connected to a first protective plate 4 through a hinge, and the top surface of the first protective plate 4 is connected to a second protective plate 5 through a rotating shaft;

[0025] It also includes a fixing assembly that can be pulled and turned over, the fixing assembly is used to fix the use position of the second protection plate 5, and the fixing assembly is connected to the first protection plate 4; when in use, firstly, the workpiece to be processed is placed between the tailstock 2 and the headstock 3, and the workpiece is fixed by adjusting the positions of the tailstock 2 and the headstock 3, and then, the cylindrical grinder body 1 is started to make the grinding tool grind the workpiece;

[0026] During the processing, in order to protect the safety of the operator and prevent the dust and debris generated by grinding from splashing, the first guard plate 4 and the second guard plate 5 need to be flipped to a suitable position. At this time, the second guard plate 5 is located above the first guard plate 4 by using the rotating shaft, and then fixed above the first guard plate 4 by using the fixing component, so that it is located at the front side of the cylindrical grinder body 1 and fits tightly. The design of the fixing component enables it to conveniently fix the use position of the second guard plate 5 while ensuring its stable connection with the first guard plate 4.

[0027] After the processing is completed, the second protective plate 5 can be flipped back to its original position by releasing the fixing component, which is not only convenient for the next processing operation, but also when installing or removing the workpiece, the second protective plate 5 can be flipped back to its original position by releasing the fixing component, so as to facilitate the operator to install or remove the disc workpiece, and avoid the height of the second protective plate 5 limiting the operator's operating space when installing or removing the disc workpiece, and avoid the disc workpiece When installing the disc workpiece, due to the limited operating space of the operator, the clamping process of the disc workpiece may be unstable, thereby avoiding affecting the grinding quality. In short, the design of this floating oil seal cylindrical grinder takes into account the safety and processing efficiency of the operator, and provides a safer and more convenient working environment for the operator through the use of fixing components and protective plates.

[0028] Reference Figure 1 , Figure 2 and Figure 3The fixing assembly also includes two fixing plates 7 that are symmetrically distributed and fixed on the first protective plate 4. A connecting rod 8 is passed through the two fixing plates 7. A connecting piece 9 is fixed at one end of the connecting rod 8, and a nut 10 is installed at the other end through a thread. The outer walls of the two connecting rods 8 are sleeved with a reset spring 11, and the reset spring 11 is located between the fixing plate 7 and the nut 10. A pull rod 12 is connected to the two connecting plates 9 through a rotating shaft. Two symmetrically distributed arc rods 13 are fixed to the pull rod 12. The outer wall of the second protective plate 5 is located above the pull rod 12 and two symmetrically distributed fixing rods 14 are fixed. , the front ends of the two fixing rods 14 are fixed with limiting plates 15; when in use, first, when the position of the second protective plate 5 needs to be fixed, the pull rod 12 can be pulled upwards, and at the same time, the nut 10 will squeeze the reset spring 11 to shrink it. At this time, the pull rod 12 is flipped over again so that the arc rod 13 can pass through the limiting plate 15 and be located above the fixing rod 14. Then, when the pull rod 12 is released, the reset spring 11 will be reset so that the arc rod 13 is hung on the fixing rod 14. At the same time, the limiting plate 15 will limit the movement of the arc rod 13, thereby preventing the pull rod 12 from flipping over again, so that the second protective plate 5 can be fixed.

[0029] Reference Figure 1 A perspective window 6 is provided on one side of the second protective plate 5, and an anti-fog film is provided on the surface of the perspective window 6; it can effectively prevent the perspective window 6 from fogging during operation, ensuring that the operator can clearly observe the grinding degree of the disc workpiece.

[0030] Reference Figure 3 The nut 10 is provided with anti-slip grooves to increase the manual friction force, making it easier for the operator to adjust the nut 10.

[0031] Reference Figure 3 The fixing rod 14 and the limiting plate 15 are both made of wear-resistant materials to increase their service life.

[0032] Reference Figure 1 A shock-absorbing pad is arranged at the bottom of the cylindrical grinder body 1 to provide the necessary shock-absorbing effect.

[0033] The implementation principle of a floating oil seal cylindrical grinder in the embodiment of the present application is as follows: when in use, first, place the workpiece to be processed between the tailstock 2 and the headstock 3, and fix the workpiece by adjusting the positions of the tailstock 2 and the headstock 3, then start the cylindrical grinder body 1 to enable the grinding tool to grind the workpiece;

[0034] When the position of the second protective plate 5 needs to be fixed, the pull rod 12 can be pulled upwards, and at the same time, the nut 10 will squeeze the reset spring 11 to shrink it. At this time, the pull rod 12 is flipped again, so that the arc rod 13 can pass through the limit plate 15 and be located above the fixing rod 14. Then, when the pull rod 12 is released, the reset spring 11 will be reset, so that the arc rod 13 is hung on the fixing rod 14. At the same time, the limit plate 15 will limit the movement of the arc rod 13, thereby preventing the pull rod 12 from flipping again, so that the second protective plate 5 can be fixed;

[0035] After the processing is completed, the second protective plate 5 can be flipped back to its original position by releasing the fixing component, which is not only convenient for the next processing operation, but also when installing or removing the workpiece, the second protective plate 5 can be flipped back to its original position by releasing the fixing component, so as to facilitate the operator to install or remove the disc workpiece, and avoid the height of the second protective plate 5 limiting the operator's operating space when installing or removing the disc workpiece, and avoid the disc workpiece When installing the disc workpiece, due to the limited operating space of the operator, the clamping process of the disc workpiece may be unstable, thereby avoiding affecting the grinding quality. In short, the design of this floating oil seal cylindrical grinder takes into account the safety and processing efficiency of the operator, and provides a safer and more convenient working environment for the operator through the use of fixing components and protective plates.
