Abstract
The utility model belongs to the technical field of process machining, and relates to an outer diameter and end face grinding device of an eccentric sleeve; the utility model discloses a grinding device is a finish machining eccentric shaft. During assembly, the high point of the wall thickness of the eccentric sleeve is coincided with the short radius of the eccentric shaft, and the error of the coincidence of the eccentric sleeve and the axis of the eccentric shaft is controlled by observing the circumferential runout of a part on a support table on a machine tool. The device can be used for positioning, clamping and grinding parts with qualified sizes of eccentric sleeve parts with different eccentric amounts, and can also realize the processing advantages of simple and easy operation, time and labor saving, great work efficiency and improved processing precision by utilizing the processing advantages of the diameter of the grinding wheel of the cylindrical grinding machine to be larger than that of the grinding wheel of the internal grinding machine, high grinding finish degree, small vibration of the shaft neck of the grinding wheel and the like.
Description
Technical Field
The utility model belongs to the technical field of the technology processing, concretely relates to external diameter and end face grinding device of eccentric bushing.
Background
The eccentric sleeve is a common part, and the inner diameter, the outer diameter and the end face of the part are ground by using an internal grinder through a four-jaw chuck or by adopting a method of aligning the eccentricity by a magnetic chuck when the part is ground. However, these two methods have many disadvantages: 1. the four-jaw chuck is adopted for alignment, and the alignment time is generally more than 20 minutes; 2. the magnetic chuck is easy to generate grinding play when the machining allowance of the part is large; 3. when the length of the outer diameter of a part is slightly long, the cutter bar of the internal grinding machine generates grinding vibration, so that the grinding straightness is poor, and the processing precision is influenced; 4. when the internal grinding machine grinds the outer diameter and the end face, the grinding finish is lower than that of an inner hole, and the grinding finish cannot be compared with that of the external grinding machine; 5. the cylindrical grinder has higher grinding efficiency and better stability than the internal grinder. In a word, the clamping is time-consuming and labor-consuming, the machining precision is low, and the machining efficiency is low.
Disclosure of Invention
The utility model aims at: the outer diameter and end face grinding device of the eccentric sleeve is provided to solve the technical problems of low machining efficiency, insufficient machining precision and poor quality existing in the existing machining method.
In order to solve the technical problem, the technical scheme of the utility model is that:
the grinding device for the outer diameter and the end face of the eccentric sleeve comprises an eccentric shaft 1 body, wherein the eccentric shaft 1 body is cylindrical;
when the eccentric sleeve is assembled, the high point of the wall thickness of the eccentric sleeve is overlapped with the short radius of the eccentric shaft, and the error of the overlapping of the eccentric sleeve and the axis of the eccentric shaft is controlled by observing the circumferential runout of a part on a support table on a machine tool.
The eccentric amount of the central hole axis on the cylindrical eccentric shaft is consistent with that of the eccentric sleeve.
The cylindrical shape of the eccentric shaft 1 is a solid structure.
The utility model has the advantages that: adopt the utility model discloses an external diameter and end face grinding device of eccentric bushing not only can be used to the part of the qualified size of location, clamp and grinding of the eccentric bushing class part of different eccentric capacities, but also can realize utilizing the big linear velocity of cylindrical grinder emery wheel diameter ratio internal grinding machine emery wheel diameter height, and grinding finish is high, and the grinding wheel axle journal shakes processing advantages such as little, reaches simple accurate, labour saving and time saving, makes great effort doubly and improves the purpose of machining precision.
Drawings
FIG. 1 is a schematic structural view of an eccentric bushing outer diameter and end face grinding device according to the present invention;
fig. 2 is a view taken along direction a of fig. 1.
Detailed Description
The outer diameter and end face grinding device of the eccentric sleeve of the present invention will be described with reference to the specific embodiment, as shown in fig. 1, the outer diameter and end face grinding device of the eccentric sleeve includes an eccentric shaft 1 body; the eccentric shaft 1 is in a solid cylinder shape, and when the eccentric shaft is assembled, the wall thickness high point of the eccentric sleeve is overlapped with the short radius of the eccentric shaft. The error of the coincidence of the axis of the eccentric sleeve and the axis of the eccentric shaft is controlled by observing the circumferential runout of the part by supporting a watch on the machine tool.
The utility model discloses a device is when using, at first marks out the eccentric high point of eccentric cover, then marks out the minor axis of eccentric shaft, slowly packs into the eccentric shaft with eccentric cover in to make two mark point coincidence. The device with the eccentric sleeve is arranged on a grinding machine, and the center holes of the two ends of the machine tool are propped by the centers of the two ends of the machine tool. The grinding of the outer diameter and end face can be started by aligning the observed part circular run-out to within 1/2 of the grinding allowance before the grinding is started.
By adopting the structure, the eccentric sleeve is conveniently positioned, clamped and ground, the original time for clamping and aligning the parts is saved, and the machining efficiency is greatly improved to 100 percent of the original time; the problem of low processing precision is solved; compared with the original clamping mode, the grinding stability is greatly improved, time and cost resources are saved, and the qualified rate of processed parts is higher. The device can also be suitable for grinding the outer diameter and the end face of other eccentric parts.
