Description

Technical Field

[0001] The utility model relates to the technical field of bearing grinding, in particular to a grinding wheel dresser for grinding the groove of the inner ring of a bearing. Background Art

[0002] It is well known that the grinding of the inner ring raceway of the bearing requires grinding wheel grinding, but the arc of the outer diameter contour of the grinding wheel and the side of the grinding wheel need to be trimmed first. The grinding wheel with arc trimming is used to grind the bearing groove, and the grinding wheel side can be used to trim the machine tool pole after linear trimming. The prior art usually adopts a set of independent arc dressers and a set of independent linear dressers. When in use, the linear dresser needs to be used first, and then the linear dresser is removed from the grinding machine and replaced with the arc dresser. Since the two dressers are heavy, the disassembly and installation require the assistance of a crane, and each installation and disassembly requires re-alignment, which is time-consuming and labor-intensive. Therefore, it has become a basic demand of technical personnel in this field to propose a grinding wheel dresser for grinding the inner ring groove of the bearing, which is simple and convenient to operate and saves physical labor. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology, the utility model discloses a grinding wheel dresser for grinding a groove of an inner ring of a bearing.

A base is fixed on the left side of the circular arc dresser. The linear dresser comprises a connecting seat, a diamond pen seat, a diamond pen and a linear guide. The linear guide is fixed on the left side of the base. The connecting seat is fixed on a slider on the linear guide. The diamond pen is fixed to the inner side surface of the front end of the connecting seat through the diamond pen seat. A fixing plate is installed on the rear end surface of the circular arc dresser. The cylinder is installed on the fixing plate through the cylinder seat. The lifting end is fixedly connected to the rear end surface of the connecting seat.

[0006] The grinding wheel dresser for grinding the inner ring groove of the bearing has limit pins protruding from the outer side of the linear guide fixed at the front and rear of the linear guide, and the slider is slidably arranged on the linear guide between the two limit pins.

[0007] The grinding wheel dresser for grinding the groove of the inner ring of the bearing has a linear guide rail fixed on a base on the side of the arc-shaped dresser by bolts.

[0008] In the grinding wheel dresser for grinding the groove of the inner ring of the bearing, the diamond pen is arranged toward the arc opening of the arc-shaped dresser.

[0009] In the grinding wheel dresser for grinding the inner raceway of the bearing, the moving stroke of the diamond pen is the dressing stroke, and the dressing stroke is greater than the dressing width of the grinding wheel.

[0010] The grinding wheel dresser for grinding the inner ring groove of the bearing has a fixing plate fixed on the rear end face of the arc-shaped dresser by bolts, and the cylinder is located on the left side of the front end face of the fixing plate.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0012] The grinding wheel dresser for grinding the inner ring groove of a bearing described in the utility model fixes a linear dresser on a traditional circular arc dresser, and a cylinder drives the linear dresser to move on the circular arc dresser, thereby realizing the circular arc dressing of the outer diameter contour of the grinding wheel and the linear dressing of the side of the grinding wheel on a set of mechanisms, avoiding repeated disassembly of the dresser during use; the utility model is easy to use and simple to operate, and effectively improves work efficiency while saving physical labor.

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with Figure 1-2The grinding wheel dresser for grinding the inner ring groove of the bearing comprises a circular arc dresser 1, a linear dresser and a cylinder 9. A base 8 is fixed on the left side of the circular arc dresser 1. The linear dresser comprises a connecting seat 6, a diamond pen seat 5, a diamond pen 4 and a linear guide 2. The linear guide 2 is fixed on the left side of the base 8 by bolts. The connecting seat 6 is fixed on the slider 3 on the linear guide 2. The diamond pen 4 is fixed on the inner side of the front end of the connecting seat 6 by the diamond pen seat 5, and the diamond pen 4 faces the circular arc dresser 1. The arc mouth direction is set; a fixing plate 10 is installed on the rear end face of the arc bow dresser 1 by bolts, the cylinder 9 is installed on the fixing plate 10 through the cylinder seat, and the lifting end is fixedly connected to the rear end face of the connecting seat 6; limit pins 7 protruding from the outer side of the linear guide rail 2 are fixed at the front and rear of the linear guide rail 2, and the slider 3 is slidably set on the linear guide rail 2 between the two limit pins 7. The two positioning pins 7 are used to limit the front and rear strokes of the slider 3 to control the entire dressing stroke and prevent the slider 3 from slipping out of the outside of the linear guide rail 2.

[0018] Furthermore, the moving stroke of the diamond pen 4 is the dressing stroke, and the dressing stroke is greater than the dressing width of the grinding wheel, and the dressing width is determined by the width of the magnetic pole of the machine tool to be dressed.

[0019] The grinding wheel dresser for grinding the inner ring groove of the bearing described in the utility model is implemented. When in use, the grinding wheel 11 is installed and fixed on the grinding wheel shaft of the machine tool. The arc-shaped dresser 1 is a prior art. The grinding wheel 11 is arc-shaped by the arc-shaped dresser 1. A base 8 is fixed on the side of the arc-shaped dresser 1 by bolts. The rear part of the linear guide 2 is fixed on the base 8. Two limit pins 7 fixed on the linear guide 2 limit the slider 3. The lifting end of the cylinder 9 is fixedly connected to the connecting seat 6 on the slider 3 of the linear guide 2. The diamond pen 4 on the inner surface of the front part of the connecting seat 6 can straighten the side of the grinding wheel 11. Line dressing; the steps of straight line dressing are as follows: first, there is an angle of 20-40° between the grinding wheel 11 and the moving direction of the linear dresser, which is actually determined by the angle of the bearing to be ground. The machine tool grinding wheel axis approaches the diamond pen 4 along the normal direction of the moving direction of the linear dresser to perform tool setting; then, the machine tool grinding wheel axis drives the grinding wheel 11 to rotate at a low speed, and the cylinder 9 drives the connecting seat 6 to make reciprocating linear motion on the linear guide 2 through the slider 3 until the tip of the diamond pen 4 contacts the side of the grinding wheel 11. Finally, dressing is started according to the grinding wheel speed required for normal dressing and the reciprocating frequency of the dresser required until the dressing is completed. Figure 2 The distance a shown in the figure is the trimmed width, and the trimmed width is determined by the pole width of the machine tool to be trimmed. The trimming stroke can be greater than the trimmed width; wherein, the cylinder 9 uses a regulating valve to control its low-speed movement and its trimming speed. The cylinder 9 and the regulating valve are both controlled to start and stop by an external PLC controller. The working principle of the control start and stop is the existing technology, so it will not be described in detail.

[0020] The parts not described in detail in this utility model are prior art.

[0021] The embodiments selected in this article for the purpose of disclosing the invention of the utility model are currently considered to be suitable, but it should be understood that the utility model is intended to include all changes and improvements of the embodiments that belong to the scope of the present concept and utility model.
