Description

Technical Field

[0001] This application relates to the technical field of gear part surface treatment equipment, and in particular to a double-barrel gear grinding device and its grinding method. Background Art

[0002] Common gear part surface treatment methods mainly include manual grinding, chemical corrosion, electrolytic polishing, and barrel finishing, etc. Among them, manual grinding is simple to operate but has low efficiency and is prone to human error; while the chemical corrosion method can quickly remove the surface oxide layer, but the surface roughness after treatment is difficult to control, and the waste liquid generated pollutes the environment; the electrolytic polishing method can achieve a high surface finish, but the equipment is complex and the cost is high, which is not suitable for large-scale production; and barrel finishing, as a relatively advanced surface treatment technology, through the mutual friction between the grinding medium in the barrel and the workpiece, achieves the purpose of improving the surface quality and morphology, and has the advantages of high efficiency and low cost.

[0003] After retrieval, the existing patent (Publication No.: CN111702631B) discloses a barrel-type grinding device for workpiece polishing, including two brackets and a hydraulic cylinder. The left end of the hydraulic cylinder is fixedly connected to the bracket on the left side. There are two grinding barrels between the two brackets. A retaining plate A is fixedly installed on the inner bottom wall of the grinding barrel on the right side. The right side surface of the grinding barrel on the right side is fixedly connected to the bracket on the right side. The output end of the hydraulic cylinder is fixedly installed with a retaining plate B. A motor A is fixedly installed below the hydraulic cylinder. By setting the grinding barrel, motor A, motor B, rotating shaft, grinding disc, and track, when the grinding barrel moves in the opposite direction to the advancing direction of the roller, a multi-directional grinding effect on the workpiece can be achieved. The inventor found the following problems in the process of realizing this application: The existing grinding and polishing equipment for grinding workpieces cannot detect the temperature and pressure during the grinding and polishing process, and cannot accurately control the working environment of gear grinding and polishing. Moreover, after the existing grinding and polishing equipment for grinding workpieces finishes grinding, it is necessary to pick out the ground parts from the grinding medium, which is rather inconvenient; Therefore, in view of the above-related technical problems, a double-barrel gear grinding device and its grinding method are proposed.

A circulating cooling device 5 is arranged between the two groups of fixed support plates 17; the grinding device main body base 1 is the connection support base of the entire grinding device, and through the sliding connection plate 12, the power connection plate 11, and the fixed support plates 17, the support structure of the device is formed. The roller motor 2 drives the driving rotating cylinder 6 and the grinding cylinder assembly 7 to perform grinding and polishing work. The heat generated by the driving rotating cylinder 6 and the grinding cylinder assembly 7 during the grinding and polishing process is absorbed by the cooling cylinder 4, and the temperature in the cooling cylinder 4 is controlled by the circulating cooling device 5 to ensure the best processing temperature. The circulating cooling device 5 is a common water-cooled circulating device, which takes away the heat in the cooling cylinder 4 during grinding production through the coolant. After the grinding work is completed, the push rod motor 13 drives the grinding cylinder assembly 7 to move to the blanking place.
