Description

Technical Field

[0001] This utility model relates to the field of CNC vertical grinding machines, and in particular to a circular arc dressing structure used on a CNC vertical grinding machine. Background Technology

[0002] With the widespread application of CNC vertical grinding machines (hereinafter referred to as vertical grinders), their grinding wheel dressing technology is also facing new challenges. Vertical grinders are mainly used to process medium and large workpieces, so the grinding wheels used are relatively large. Traditional grinding wheel dressing uses diamond dressing tools, but this method has obvious limitations: long dressing time, low efficiency, and the continuous stress on the equipment during the dressing process accelerates wear and aging. In addition, for cylindrical parts with curved inner cavities or outer walls, traditional diamond dressing tools cannot dress curved grinding wheels, making it difficult to meet the required machining accuracy for such workpieces. Therefore, there is an urgent need for a technical solution that can efficiently and accurately dress curved grinding wheels to solve the problems of low efficiency, insufficient accuracy, and severe equipment wear associated with traditional dressing methods. Utility Model Content

[0003] This application provides a circular arc dresser structure for use on a CNC vertical grinding machine, which solves the technical problem that in the prior art, grinding wheel dressing is mostly done with diamond pens, but diamond pens cannot dress circular arc grinding wheels, resulting in the machining accuracy of such workpieces being difficult to meet the requirements.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A circular arc dressing structure for use on a CNC vertical grinding machine includes a base, a cradle rotating arm, a diamond roller, a slider, a diamond roller electric spindle, a housing, linear guides, a cylinder, a cylinder connecting plate, a motor shaft, a shaft core, and a planetary reducer. The base has a double-ear plate side-hinged structure. The motor shaft and the shaft core are respectively connected to both ends of the base via bearings. The two ends of the cradle rotating arm are respectively connected to the motor shaft and the shaft core. One end of the motor shaft is connected to the planetary reducer. A sliding opening is provided in the middle of the cradle rotating arm. Linear guides are provided at both ends of the top of the cradle rotating arm. The slider is slidably connected to the two sets of linear guides. The housing is mounted on the slider. The diamond roller electric spindle is mounted in the housing and is drivenly connected to the diamond roller. The cylinder is mounted at the bottom of the cradle rotating arm. The cylinder piston rod is connected to the cylinder connecting plate, and the cylinder connecting plate is connected to the housing.

[0006] A further technical solution is to provide limiting seats at both ends of the linear guide rail.

[0007] A further technical solution is as follows: a front cover and a rear cover are installed at the connection between the shaft and the cradle rotating arm; a waterproof ring is provided between the front cover and the shaft.

[0008] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0009] 1. This arc dressing device, by incorporating a base, cradle rotating arm, diamond roller, slider, diamond roller electric spindle, housing, linear guide rail, cylinder, cylinder connecting plate, motor shaft, shaft core, and planetary reducer, replaces the traditional diamond pen with a bowl-shaped diamond roller, upgrading point contact dressing to line contact, significantly improving dressing efficiency. The diamond roller, driven by the electric spindle, achieves high-speed rotation, ensuring higher surface finish and precision on the dressed grinding wheel. The cradle rotating arm, connected to the rotating spindle via a planetary reducer, allows for large-angle rotation, meeting the shaping and dressing needs of grinding wheels of different thicknesses and enriching process diversity. The coordinated design of the linear guide rail and cylinder allows the diamond roller to move left and right, adapting to dressing requirements of different arc diameters. The base adopts a double-ear plate side-hinged structure, effectively avoiding interference with the internal grinding head. Furthermore, the limit seat ensures the accuracy and safety of the diamond roller's movement, while the front cover and waterproof ring design improve the device's durability and stability. With its reasonable overall structural design and simple operation, it not only greatly improves the efficiency and accuracy of grinding wheel dressing, but also reduces equipment wear and extends the service life of the equipment.

[0023] Start the electric spindle 5 of the diamond roller, which drives the diamond roller 3 to rotate at high speed.
