High-precision Curvature Regulating Mechanism of Mechanical Track Seat

Abstract

The invention discloses a high-precision curvature regulating method for a mechanical railroad shoe. The method comprises the following steps: a, providing a mechanical railroad shoe by refining; b, installing a regulating mechanism; and c, regulating a curvature of the mechanical railroad shoe. A containing part and a containing groove are opening in the mechanical railroad shoe, and the regulating mechanism is installed inside the containing part and the containing groove, wherein the regulating mechanism comprises a regulating rod, two clamping pieces and two regulating elements. When rotating the regulating elements of the regulating mechanism, the regulating mechanism applies an axial stress onto the mechanical railroad shoe. Due to the fact that the stress is applied onto one side of the mechanical railroad shoe and is not on the central axis of the mechanical railroad shoe, the mechanical railroad shoe is bended to one side under the effect of the moment of force, accordingly the user can operate the regulating elements to regulate the curvature of the mechanical railroad shoe.

Description

technical field [0001] The invention relates to a method for adjusting a mechanical rail seat, in particular to a control method for users to adjust the curvature of the surface of the mechanical rail seat. Background technique [0002] In the process of mechanical processing, especially for milling and planing, in order to carry out the same process for multiple objects to be processed at one time to improve processing efficiency, they generally place multiple objects to be processed on a mechanical track seat. The objects to be processed are continuously fed into the tool machine for processing sequentially, whereby multiple processed products can be obtained in one processing process. [0003] However, it is difficult to keep the surface of the existing mechanical track seat completely straight.

[0003] However, the surface of the existing mechanical track seat is difficult to keep completely straight

For example, in the process of manufacturing and processing, a first surface of the mechanical rail base must be ground into a plane and undergo other surface treatments. During the process of grinding or surface treatment, the first surface will be heated and slightly Expansion, while a second surface opposite to the first surface is not expanded due to unprocessed, resulting in the first surface of the mechanical track seat slightly convex and the second surface concave, at this time, due to the processing During the process of processing, it has been measured that the first surface is convex instead of flat, so the part of the first surface that is convex on the plane is cut off again, but a slight expansion occurs due to the temperature rise during the cutting, Then it is planed off again, and after repeated many times, although the mechanical track seat can still temporarily become the first surface with high straightness in the end, once the surface temperature cools down, it will be like this figure 1 As shown, the first surface 11 of the mechanical track base 10 that originally became a plane with high straightness due to expansion retracts, causing the first surface 11 to be concave and the second surface 12 to be convex, resulting in the straightness of the mechanical track base 10 poor degree

[0004] In addition, because the mechanical track base 10 has a large mass and its height-to-length ratio is small, it is also easy to bend downward in the middle part due to the influence of gravity, resulting in poor straightness during processing.

[0005] Therefore, the straightness of the existing mechanical rail seat 10 is difficult to accurately grasp, and when using the mechanical rail seat 10 with poor straightness to continuously send a plurality of objects to be processed into the machine tool for sequential processing, due to various The objects to be processed are not located on a plane of equal height, so the degree of processing of each object to be processed will be inconsistent, resulting in unstable tolerance values ​​of finished products after processing, and poor yield of finished products
