Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of eccentric sleeve processing, and in particular relates to a grinding processing tool for a semi-connected eccentric sleeve. Background Art
[0002] like Figure 1 The semi-connected eccentric sleeve shown has a structure including two eccentric sleeves arranged at both ends and a connecting part arranged in the middle for connecting the two eccentric sleeves. When the inner eccentric hole of the eccentric sleeve is polished and finished, due to the large overall length of the structure, the eccentric sleeves at both ends are subjected to different forces during the processing. In conventional processing, the errors generated during the grinding production process cannot be avoided. At the same time, the higher the production accuracy of the eccentric sleeve and the eccentric shaft, the better the fit. A few millimeters of production error will seriously affect the quality of the finished product. Therefore, in order to improve the processing accuracy of the eccentric sleeve and ensure product quality, it is necessary to design a processing tooling to ensure the processing effect of the eccentric sleeve.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Reference Figure 1-3 A grinding tool for a semi-connected eccentric sleeve comprises a bottom fixing portion 3 and a lateral balancing portion 2, wherein the bottom fixing portion 3 comprises a base plate 31, a high-precision linear module 32 is mounted on the base plate 31, an assembly table composed of a bottom plate 33 and a panel 34 is mounted on the high-precision linear module 32, a clamping sleeve 36 is fixedly connected to the assembly table, and the clamping sleeve 36 is fixedly connected to the bottom of the semi-connected eccentric sleeve 1;
[0019] The lateral balancing part 2 is arranged on the side of the semi-connected eccentric sleeve 1 and is arranged opposite to the middle connecting part of the semi-connected eccentric sleeve 1. The lateral balancing part 2 includes two upper and lower connecting end plates 21 and a roller body 22. The roller body 22 is fixedly arranged between the two sets of connecting end plates 21.
[0020] In view of the problem that the existing semi-connected eccentric sleeve 1 is difficult to process and inconvenient to control the processing accuracy of the eccentric sleeve, this scheme proposes a grinding processing tool for the semi-connected eccentric sleeve, so as to assist the processing of the semi-connected eccentric sleeve 1 and ensure the processing accuracy of the semi-connected processing sleeve. Specifically, the processing tool includes a bottom fixing part 3 and a lateral balancing part 2. The bottom fixing part 3 is directly fixedly connected to the bottom of the semi-connected eccentric sleeve 1, so that the semi-connected eccentric sleeve 1 is horizontally assembled. The lateral balancing part 2 is used to balance the semi-connected eccentric sleeve 1 so that the left and right ends of the semi-connected eccentric sleeve 1 remain balanced. During the processing, the force on the semi-connected eccentric sleeve 1 can be kept uniform and stable, thereby avoiding the instability caused by vibration of the semi-connected eccentric sleeve 1 during the processing. During the grinding process, the processing of the upper and lower parts of the semi-connected eccentric sleeve 1 is kept consistent, which greatly reduces the deviation between the upper and lower parts of the semi-connected eccentric sleeve 1 during the processing, thereby greatly improving the processing accuracy of the semi-connected eccentric sleeve 1 and ensuring the processing quality of the product.
[0021] Furthermore, a plurality of roller bodies 22 are provided, and the plurality of roller bodies 22 are symmetrically arranged along the center line of the lateral balancing portion 2 .
[0022] In the structure of the semi-connected eccentric sleeve 1, the upper and lower ends are two coaxial eccentric sleeves, and the two eccentric sleeves are fixedly connected by an intermediate connecting part, and the intermediate connecting part is placed on one side of the eccentric sleeves at both ends; the roller body 22 of the lateral balancing part 2 is arranged opposite to the intermediate connecting part (the lateral balancing part 2 and the intermediate connecting part are arranged nearly symmetrically), so as to keep the two ends of the eccentric sleeve balanced; the center line of the lateral balancing part 2 refers to the bisector of the connecting end plate 21, and multiple groups of roller bodies 22 are symmetrically arranged along the center line of the lateral balancing part 2, which can effectively ensure that the connection of the lateral balancing part 2 is stable, which is beneficial to maintain the stability of the semi-connected processing sleeve during the processing.
[0023] Furthermore, the height of the lateral balancing portion 2 is consistent with the height of the middle connecting portion of the semi-connected eccentric sleeve 1 , and the weight of the lateral balancing portion 2 is consistent with the weight of the semi-connected eccentric sleeve 1 .
[0024] Through this technical solution, the weight of the lateral balancing part 2 is kept equal to the height and weight of the semi-integrated eccentric sleeve 1, and the overall structural center of gravity of the semi-integrated eccentric sleeve 1 and the lateral balancing part 2 can be kept in the middle as much as possible, which improves the stability during the grinding process.
[0025] Furthermore, a plurality of pads 35 are arranged on the top of the panel 34, and the pads 35 are made of ductile iron.
[0026] The surface of the pad 35 is manually polished after mechanical fine processing to maintain the flatness of the surface of the pad 35, thereby ensuring the horizontality of the semi-connected eccentric sleeve 1 and higher processing accuracy; the pad 35 is made of ductile iron as a whole, which has good wear resistance and stability and is not easy to deform, thereby ensuring the processing stability of the tooling.
[0027] Furthermore, the motor of the linear module is a servo motor.
[0028] The linear module is used to drive the eccentric sleeve to move and cooperate with the grinder for processing; the servo motor can accurately drive and accurately control the stroke, thereby ensuring the processing accuracy.
[0029] Furthermore, the panel 34 and the bottom plate 33 are fixedly connected by bolts, and a directional bolt 37 is also provided on one side of the panel 34 .
[0030] Since the eccentric sleeve is processed eccentrically, there is a direction in the processing process, and the directional bolt 37 can effectively indicate the direction to prevent the semi-connected eccentric sleeve 1 from being installed upside down.
[0031] Working principle: The semi-connected eccentric sleeve 1 is processed with the assistance of a grinding tool. The grinding tool includes a bottom fixing part 3 and a lateral balancing part 2. The bottom fixing part 3 is directly fixedly connected to the bottom of the semi-connected eccentric sleeve 1, so that the semi-connected eccentric sleeve 1 is assembled horizontally. The lateral balancing part 2 is used to balance the semi-connected eccentric sleeve 1, so that the left and right ends of the semi-connected eccentric sleeve 1 remain balanced. During the processing, the force on the semi-connected eccentric sleeve 1 can be kept uniform and stable, thereby avoiding the semi-connected eccentric sleeve 1 from vibrating and remaining unstable during the processing. During the grinding process, the processing of the upper and lower parts of the semi-connected eccentric sleeve 1 is kept consistent, which greatly reduces the deviation of the upper and lower parts of the semi-connected eccentric sleeve 1 during the processing, thereby greatly improving the processing accuracy of the semi-connected eccentric sleeve 1 and ensuring the processing quality of the product.
