Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel technology, and in particular to a marine grinding wheel with self-lubricating cooling holes. Background Technology
[0002] A grinding wheel is a circular tool used for grinding, cutting, polishing, and other processes. It typically consists of abrasive grains, a binder, and a fiber backing plate. It removes excess material from the surface of a material through high-speed rotation to achieve the desired dimensions and surface finish. Grinding wheels are widely used in metal processing, stone cutting, and other fields. In shipbuilding, marine grinding wheels are used to clean welds, weld joints, burrs, rough edges, and repair surface defects in metals.
[0003] When traditional marine grinding wheels are used to cut and process parts manufactured for ships, the cutting surface temperature of the continuous operation marine grinding wheels can reach over 300°C. Due to their poor heat dissipation, marine grinding wheels are prone to damage due to high temperatures, thus reducing their service life.
[0004] Therefore, it is necessary to propose a marine grinding wheel with self-lubricating cooling holes to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a marine grinding wheel with self-lubricating cooling holes, in order to solve the problem mentioned in the background art that the marine grinding wheel is easily damaged due to high temperature due to poor heat dissipation, thereby reducing the service life of the marine grinding wheel.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine grinding wheel with self-lubricating cooling holes, comprising a grinding wheel body, wherein the grinding wheel body comprises a first grinding wheel clasp and a second grinding wheel clasp;
[0007] Cooling holes are provided inside both the first and second grinding wheel pieces, and guide grooves are provided inside the contact surfaces of both the first and second grinding wheel pieces.
[0008] Preferably, the cooling holes are provided in multiple ways, and the multiple cooling holes are arranged in a spiral through-hole structure.
[0009] Preferably, one end of the guide groove penetrates the outside of the grinding wheel body, and the other end of the guide groove penetrates the inner wall of the cooling hole, and the guide groove is V-shaped.
[0010] Preferably, both the first and second grinding wheel pieces have mounting holes inside, and both the surfaces of the first and second grinding wheel pieces that are far apart from each other have mounting grooves inside.
[0011] Preferably, a mounting plate is snapped into the inside of the mounting slot, a mounting bolt is inserted into the inside of the mounting plate, and a mounting nut is connected to the external thread of the mounting bolt;
[0012] The mounting bolt penetrates the interior of the mounting hole.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] By combining cooling holes and guide grooves, the centrifugal force generated by the rotation of the grinding wheel body creates a vortex airflow within the cooling holes, accelerating heat dissipation from the grinding wheel body. Furthermore, a semi-solid lubricant can be added to the guide grooves. As the grinding wheel body rotates, the semi-solid lubricant slowly seeps out along the guide grooves, forming a lubricating and cooling film on the outside of the grinding wheel body. This improves cutting performance and protects the grinding wheel body. Simultaneously, the guide grooves and cooling holes form a three-dimensional heat dissipation network, which, together with the lubricating film, reduces the temperature of the cutting interface, bringing convenience to the use of the grinding wheel body.

[0021] 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.
[0022] This utility model provides, for example Figures 1-5 The marine grinding wheel with self-lubricating cooling holes shown includes a grinding wheel body 1. The grinding wheel body 1 includes a first grinding wheel slab 101 and a second grinding wheel slab 102. Cooling holes 1011 are provided inside the first grinding wheel slab 101 and the second grinding wheel slab 102. Guide grooves 1012 are provided inside the contact surfaces of the first grinding wheel slab 101 and the second grinding wheel slab 102.
[0023] The cooling holes 1011 are provided in multiple ways, and the multiple cooling holes 1011 are arranged in a spiral through-hole structure. The centrifugal force generated by the rotation of the grinding wheel body 1 can be used to form a vortex airflow within the cooling holes 1011, which accelerates the heat dissipation of the grinding wheel body 1 and improves the heat dissipation effect of the grinding wheel body 1.
[0024] In addition, one end of the guide groove 1012 penetrates the outside of the grinding wheel body 1, and the other end of the guide groove 1012 penetrates the inner wall of the cooling hole 1011. The guide groove 1012 is V-shaped. Semi-solid lubricating coolant can be added to the inside of the guide groove 1012. As the grinding wheel body 1 rotates, it slowly seeps out along the guide groove 1012 and forms a lubricating cooling film on the outside of the grinding wheel body 1 to improve the cutting effect and protect the grinding wheel body 1. At the same time, the guide groove 1012 and the cooling hole 1011 form a three-dimensional heat dissipation network, which, together with the lubricating film, reduces the temperature of the cutting interface, bringing convenience to the use of the grinding wheel body 1.
[0025] Finally, both the first grinding wheel assembly 101 and the second grinding wheel assembly 102 have mounting holes 1013 inside, and both have mounting grooves 1014 inside their surfaces that are far apart. A mounting disc 2 is engaged inside the mounting groove 1014, and a mounting bolt 3 is inserted inside the mounting disc 2. A mounting nut 4 is threaded onto the outside of the mounting bolt 3, which passes through the mounting hole 1013. The two mounting discs 2 can be respectively engaged in the mounting grooves 1014 of the first grinding wheel assembly 101 and the second grinding wheel assembly 102. Adhesive is then applied to the two contact surfaces, and the mounting bolts 3 and the mounting nuts 4 are used to fix the first grinding wheel assembly 101 and the second grinding wheel assembly 102. The mounting bolts 3 are inserted into the mounting holes 1013 of the first grinding wheel assembly 101 and the second grinding wheel assembly 102, and the mounting nuts 4 are used to lock them in place, thus facilitating the fixing of the grinding wheel body 1.
[0026] Working principle: First, the grinding wheel body 1 is fixedly installed on the cutting machine. The centrifugal force generated by the rotation of the grinding wheel body 1 driven by the cutting machine forms a vortex airflow in the cooling hole 1011, which accelerates the heat dissipation of the grinding wheel body 1 and improves the heat dissipation effect. Semi-solid lubricating coolant can be added to the inside of the guide groove 1012. As the grinding wheel body 1 rotates, it slowly seeps out along the guide groove 1012 and forms a lubricating cooling film on the outside of the grinding wheel body 1 to improve the cutting effect and protect the grinding wheel body 1. At the same time, the guide groove 1012 and the cooling hole 1011 form a three-dimensional heat dissipation network, which, together with the lubricating film, reduces the temperature of the cutting interface and brings convenience to the use of the grinding wheel body 1.
