Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a wear-resistant rocker arm. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. By operating a CNC machine tool, complex and precise parts processing problems can be well solved. When using a CNC machine tool, the rocker arm needs to be well controlled. The rocker arm is a mechanical component, generally composed of an arm and a rotating shaft. The main function of the rocker arm is to transmit power or control the direction of movement.

[0003] Some existing rocker arm mechanisms have relatively poor wear resistance, and are prone to wear after long-term use, which reduces the performance of the rocker arm mechanism and reduces the service life of the rocker arm mechanism. Therefore, technical personnel in this field provide a wear-resistant rocker arm to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a wear-resistant rocker arm, which can improve the overall surface strength of the rocker arm mechanism under the action of the surface reinforcement layer of the rocker arm mechanism. At the same time, the overall wear resistance of the rocker arm mechanism can be improved under the action of the wear-resistant layer, thereby avoiding wear of the rocker arm mechanism after long-term use, thereby extending the service life of the rocker arm mechanism to a certain extent.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant rocker arm, comprising a rocker arm mechanism, wherein a plurality of fixing mechanisms are clamped and arranged on the front surface of the rocker arm mechanism;

[0006] The rocker arm mechanism includes two semicircular hollow columns and a base layer, the upper end surface of the base layer is fixedly connected to a reinforcement layer, the upper end surface of the reinforcement layer is fixedly connected to a wear-resistant layer, and multiple fixed mechanisms include circular columns and rotating blocks, multiple upper end surfaces of the rotating blocks are fixedly connected to connecting rods, and multiple upper end surfaces of the connecting rods on one side away from the center are fixedly connected to magnetic blocks.

[0007] Through the above technical scheme, the hardness of the entire rocker mechanism can be improved under the action of the reinforcing layer of the rocker mechanism, so as to avoid the rocker mechanism from bending during operation, which makes the entire rocker mechanism unable to work normally. At the same time, the wear-resistant layer can improve the overall wear resistance of the rocker mechanism, and extend the service life of the rocker mechanism to a certain extent. Under the action of the rotating block of the fixing mechanism, the connecting rod can be unfolded by rotating the rotating block, so that the magnetic block on one side of the connecting rod can magnetically attract the connecting plate, and the two semicircular hollow columns are fixed together in this way.

[0008] Furthermore, one side surface of the two semicircular hollow columns is fixedly connected with a connecting shaft, and the other side surface of the two semicircular hollow columns is fixedly connected with a connecting plate;

[0009] Through the above technical solution, the grinding mechanism of the CNC machine tool can be displaced at the front end of the connecting shaft under the action of the connecting shaft, and the main function of the connecting plate is to fix the two semicircular hollow columns together.

[0010] Furthermore, a fixed rod is fixedly connected to a surface of one side of the upper end of one of the two connecting shafts, and a long sliding groove rod is fixedly connected to a front surface of the other connecting shaft of the two connecting shafts;

[0011] Through the above technical solution, the entire rocker arm mechanism can be fixed on the CNC machine tool under the action of the fixing rod, and the main function of the long slide rod is to allow the grinding mechanism of the CNC machine tool to be unique on its surface.

[0012] Furthermore, the reinforcement layer includes a metal layer, and a polyurethane resin layer is fixedly connected to the upper surface of the metal layer;

[0013] Through the above technical solution, the strength of the entire rocker mechanism can be provided under the action of the metal layer, and at the same time, the action of the polyurethane resin layer can not only improve the strength of the rocker mechanism surface, but also enhance the wear resistance of its surface.

[0014] Furthermore, the wear-resistant layer includes a wear-resistant polymer layer, and the upper end surface of the wear-resistant polymer layer is fixedly connected with a wear-resistant coating;

[0015] Through the above technical solution, the combined use of the wear-resistant polymer layer and the wear-resistant coating of the wear-resistant layer can improve the overall wear resistance of the rocker arm mechanism.

[0016] Further, the upper end surface of the circular column is fixedly connected to an electric telescopic rod, and the upper end surface of the electric telescopic rod is fixedly connected to a circular block;

[0017] Through the above technical solution, the unfolded connecting rod can be shortened under the action of the electric telescopic rod, so that the semicircular hollow column and the connecting shaft are more closely connected. The main function of the circular block is to provide a rotating space medium for the rotating block.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model proposes a wear-resistant rocker arm, which can not only improve the overall strength of the rocker arm mechanism, but also enhance the wear resistance of its surface through the mutual cooperation of the metal layer and the polyurethane resin layer inside the reinforcement layer of the rocker arm mechanism. At the same time, the wear resistance of the rocker arm mechanism as a whole can be improved under the action of the wear-resistant layer of the rocker arm mechanism, thereby avoiding the relatively poor wear resistance of the existing rocker arm mechanism, which makes the rocker arm mechanism prone to wear after long-term use, reduces the performance of the rocker arm mechanism to a certain extent, and reduces the service life of the rocker arm mechanism.

[0020] 2. The utility model proposes a wear-resistant rocker arm, which is inserted into the connection between the two semicircular hollow columns and the connecting shaft through a fixing mechanism, and then the two connecting rods are unfolded under the action of a rotating block, and then the electric telescopic rod is shortened. In this way, the two semicircular hollow columns and the connecting shaft are fixed together, and this method is convenient for disassembly and installation of the two, avoiding the inconvenience of installation and disassembly of the two in the existing method of threaded connection using bolts.

[0032] The overall strength of the surface of the rocker mechanism 1 can be improved by the metal layer 10601 and the polyurethane resin layer 10602 of the reinforcing layer 106. At the same time, the wear-resistant polymer layer 10701 and the wear-resistant coating 10702 of the wear-resistant layer 107 can improve the overall wear resistance of the rocker mechanism 1.
