Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rail processing, in particular to a precision ceramic grinding wheel for processing linear guide rails. Background Art

[0002] Grinding wheel is a bonded abrasive tool which is made of ordinary abrasives bonded by a binder into a certain shape, mostly circular, with a through hole in the center and a certain strength. It is generally composed of abrasives, binders and pores. Grinding wheel is the most widely used and most widely used abrasive tool. It rotates at high speed when used and can perform rough grinding, semi-finishing grinding and fine grinding on the outer circle, inner circle, plane and various surfaces of metal or non-metal workpieces, as well as grooving and cutting.

[0003] Ceramic grinding wheels are often used in the precision grinding production of linear guides. In the process of grinding the upper surface of the linear guide with the ceramic grinding wheel, since the width of the grinding wheel is larger than the width of the linear guide, after a period of grinding, the grooves of the grinding wheel will be concave in the middle and protruding on both sides. When the grinding wheel has deeper grooves, it will affect the sides of the linear guide, resulting in uncontrollable grinding effect and affecting the grinding accuracy. If a new grinding wheel is directly replaced, it will increase the cost and waste the grinding wheel material. Therefore, this technical solution is proposed for improvement. Utility Model Content

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3As shown: A precision ceramic grinding wheel for processing linear guide rails includes a raw material disc 1. The raw material disc 1 can be made of metal, resin, plastic, etc. The raw material disc 1 ensures good structural strength and can ensure the stability and durability of the grinding wheel. The raw material disc 1 is processed to ensure that the surface is flat and smooth without obvious defects and burrs. A mounting hole is set in the middle position of the raw material disc 1. The raw material disc 1 is fixed on the processing equipment through the mounting hole, which is convenient for fixing the grinding wheel and determining the installation position, and is easy to use.

[0020] An annular first grinding surface 101 is provided on the outer edge of the raw material disk 1, and an annular second grinding surface 102 is provided on the outer side of the first grinding surface 101 through a connecting device. The connecting device is a fixed disk 2 arranged on the outer sides of the first grinding surface 101 and the second grinding surface 102. A first connecting hole 201 connected to the raw material disk 1 is provided in the middle position of the fixed disk 2. The diameter of the fixed disk 2 is larger than the diameter of the first grinding surface 101 and smaller than the diameter of the second grinding surface 102. The fixed disk 2 is glued to the side of the second grinding surface 102 to ensure that the fixed disk 2 can stably support the second grinding surface 102. The fixed disk 2 is connected to the side of the second grinding surface 102 by gluing to ensure the firmness and stability of the connection.

[0021] The fixed plate 2 can also be connected to the side of the second grinding surface 102 through a fixing bolt. When grinding multiple linear guide rails or grinding a linear guide rail with a wider width, a wider and heavier grinding wheel will be used. Multiple fixing bolts are used on the heavier grinding wheel to connect to the second grinding surface 102 to ensure the stability of the connection and enhance controllability.

[0022] The first grinding surface 101 and the second grinding surface 102 contain diamond grinding wheels with ceramic binders. The ceramic binders have excellent high temperature resistance and chemical stability, which can ensure the stability and service life of the diamond grinding wheels. The high hardness and wear resistance of the diamond grinding wheel enable the grinding wheel to efficiently and accurately grind the linear guide rails under high-speed rotation. Grinding with a ceramic grinding wheel can ensure structural strength and use effect. A colored adhesive is provided between the first grinding surface 101 and the second grinding surface 102. A colored adhesive is provided between the first grinding surface 101 and the second grinding surface 102. This adhesive can not only enhance the connection strength between the grinding surfaces, but also distinguish different grinding surfaces by color identification, which is convenient for users to identify and select when using. The width of the first grinding surface 101 is less than or equal to the width of the second grinding surface 102. When in use, the second grinding surface 102 will be used first. The middle position of the second grinding surface 102 will gradually sink downward during grinding. When the junction of the first grinding surface 101 and the second grinding surface 102 is used, the fixed plates 2 on both sides are removed, and the adhesive is cleaned from the gaps at the connections on both sides with a cleaning agent to separate the first grinding surface 101 and the second grinding surface 102. The exposed first grinding surface 101 can be used to re-grind the linear guide rail, or to grind the narrower linear guide rail. The re-exposed first grinding surface 101 greatly improves the utilization rate of the grinding wheel, reduces material waste, and improves production results.
