[0001] This utility model belongs to the field of mechanical processing technology, and more specifically relates to a grinding groove device with rolling bearing auxiliary support. Background Technology

[0002] Machine tools are the mother of all kinds of high-precision and high-efficiency machinery. With the development of the new energy market, automobile compressors and air conditioning compressors are developing towards high speed, high precision and high reliability. Cylinders are one of the most important components of mechanical equipment.

[0003] Because the cylinder bore is small and the blade grooves need to be ground through, the grinding wheel shank needs to be slender in order to avoid machining interference. This characteristic leads to insufficient rigidity of the shank, which in turn causes deformation due to cutting force. Therefore, there is an urgent need for a spindle structure that can improve the machining stability of the grinding wheel shank. Utility Model Content

[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] See attached document Figure 1 To be continued Figure 4 As shown, a grinding device with rolling bearing auxiliary support includes a spindle 1, a grinding processing component 2 disposed at the output end of the spindle 1, a bearing support device 3, and an external component 5 with oil mist lubrication function, wherein the spindle 1 can be a BT30 electric spindle or a mechanical spindle.

[0031] In one embodiment of this utility model, the grinding groove processing assembly 2 includes a grinding wheel holder 21 connected to the spindle 1, a grinding wheel 22 disposed at the other end of the grinding wheel holder 21, and a fixing nut 23 for mounting the grinding wheel 22 on the grinding wheel holder 21. The grinding wheel holder 21 and the spindle 1 are coaxially arranged. The rotation of the spindle 1 drives the grinding wheel 22 to rotate, so as to perform grinding processing operation on the workpiece valve plate groove.

[0032] In one embodiment of this utility model, a bearing support device 3 is provided on the outer side of the grinding wheel 22. The bearing support device 3 includes a bearing 31 sleeved on one end of the grinding wheel handle 21, a cover plate 32 provided on the side of the bearing 31 away from the grinding wheel 22, a mounting sleeve 34 fixedly connected to the spindle 1, and a mounting plate 35 threadedly connected to the mounting sleeve 34. The bearing 31 is mounted on the front end of the grinding wheel handle 21 by the mounting sleeve 34 and the mounting plate 35.

[0033] In one embodiment of this utility model, the mounting sleeve 34 is semi-cylindrical with a window on one side for easy observation. The pressure plate 33 and the mounting plate 35 are both fan-shaped and are concentrically arranged, which optimizes the structure and avoids vibration during the grinding process.

[0034] In one embodiment of the present invention, the bearing 31 is disposed at the end of the mounting plate 35 away from the mounting sleeve 34, and a spacer 4 is provided between the bearing 31 and the grinding wheel 22 so that the bearing 31 is connected to the grinding wheel handle 21 through the spacer 4.

[0035] By adding a bearing 31 to the front end of the originally slender grooving wheel holder 21, vibration during the grinding process can be effectively reduced, ensuring machining accuracy and quality. Furthermore, the addition of the bearing 31 provides rigidity to the grooving wheel holder 21, preventing deformation caused by cutting forces and improving machining stability. This makes the grooving wheel holder 21 more stable during grinding, which is beneficial for improving the perpendicularity, straightness, and width accuracy of the valve plate groove.

[0036] In one embodiment of this utility model, a pressure plate 33 is provided on the outer side of the cover plate 32, which is in spherical contact with the cover plate 32. Through the spherical contact between the pressure plate 33 and the cover plate 32, the preload applied to the bearing end can be evenly distributed, thereby eliminating gaps, improving structural rigidity, and optimizing operational stability.

[0037] In one embodiment of this utility model, the external component 5 is used to lubricate the bearing 31 with oil mist. The external component 5 includes a first flow channel 331 provided in the pressure plate 33, a second flow channel 321 that can lead gas into the bearing 31, and an air pipe connector 7 provided at one end of the pressure plate 33 away from the cover plate 32. The air pipe connector 7 is connected to the first flow channel 331. The first flow channel 331 is provided along the length direction of the pressure plate 33. The second flow channel 321 is located in the cover plate 32 and is perpendicular to the first flow channel 331. The air pipe connector 7 serves as the air inlet. After passing through the first flow channel 331 and the second flow channel 321, the bearing 31 can be lubricated with oil mist.

[0038] In one embodiment of this utility model, a accommodating cavity 6 is provided at the connection between the first flow channel 331 and the second flow channel 321, which allows gas to accumulate to a certain extent. The inner diameter of the accommodating cavity 6 is larger than the inner diameter of the first flow channel 331, and the inner diameter of the first flow channel 331 is larger than the inner diameter of the second flow channel 321. This not only improves efficiency during ventilation operation but also avoids internal pressure problems caused by the difference in inner diameter between the first flow channel 331 and the second flow channel 321. Furthermore, gas is introduced into the bearing 31 through the air pipe connector 7 to achieve oil mist lubrication, thereby reducing vibration and friction of the bearing 31 and the grinding wheel holder 21, extending service life, and improving processing efficiency.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
