Description

Cushion block for machining Technical Field The utility model relates to the technical field of machining, in particular to a cushion block for machining. Background In the field of machining, the cushion block is used as an indispensable auxiliary tool and is widely applied to a plurality of operation links such as machine tool machining, die assembly, mechanical part assembly and the like. In the process of assembling the automobile die, when all parts of the large-scale die are spliced, the cushion blocks are used for supporting and adjusting the relative positions among the parts, the die clamping precision of the die is ensured, and the quality problems of flash, inconsistent size and the like of injection products caused by position deviation are avoided. However, conventional machining blocks have exposed a number of drawbacks in practical applications. Firstly, the structural form is single and fixed, and most of the structural forms are standard parts in block or plate shape, and the height and the supporting point position cannot be flexibly adjusted according to the special shape and the size requirements of the workpiece. When processing special-shaped workpieces, the standard cushion block is difficult to fit with the outline of the workpiece, and often needs to be manually added for overlaying or cutting transformation of the cushion block, so that the operation is complex and the precision is difficult to guarantee. Secondly, the positioning mode is simple and crude, most cushion blocks are fixed by only depending on the friction force between the cushion blocks and a working table surface or simple bolts, and displacement or looseness is very easy to occur under the action of vibration generated by high-speed operation of a machine tool or larger external force applied in the assembly process of a die, so that the processing position of a workpiece is offset, the processing yield is reduced, and equipment faults such as cutter damage, die collision and the like can be possibly caused. In addition, when the existing cushion block faces the multi-point support requirement under the complex working condition, an effective adjusting mechanism is lacked, uniform stress support on a workpiece is difficult to realize, and the application of the cushion block in the field of high-end precision machining is further limited. Therefore, aiming at the urgent demands on the flexibility, stability and adaptability of the cushion block in the current machining, the development of a novel cushion block for machining, which can flexibly adjust the height and the supporting position, is stable and reliable in positioning and suitable for complex working conditions, has become a key point for improving the machining efficiency and the product quality.
