Abstract

The invention discloses a displacement device of a processing machine tool and a processing machine tool with the displacement device. The disclosed displacement device includes a displacement frame body, a driving mechanism and a plurality of roller shafts, the lower end of the displacement frame body is fixed to the workbench of the processing machine tool; the roller shafts are rotatably installed on the upper part of the displacement frame body to form a working plane area ; The roller shafts are driven by the driving mechanism to rotate around their centerlines, and the centerlines of the plurality of roller shafts are all parallel to the spindle axis of the processing machine tool. When using the displacement device provided by the present invention, the workbench can be moved an appropriate distance relative to the bed frame body, and then the roller shaft is driven to rotate through the driving mechanism, so that the parts can move an appropriate distance relative to the displacement device, and the parts The distance moved relative to the main shaft of the processing machine tool is the sum of the two distances; therefore, the displacement device provided by the present invention and the processing machine tool with the displacement device can make the parts move a greater distance relative to the axis of the main shaft, satisfying The need to process large-distance structural parts.

Description

technical field [0001] The invention relates to a machining technology, in particular to a displacement device and a processing machine tool with the displacement device. Background technique [0002] At present, machine tool equipment is widely used in product processing. As the structure of the parts itself becomes more and more complex, the size requirements between the multiple structures of the parts themselves are getting higher and higher, and the machining technology is also constantly improving and developing. In order to control the dimensional tolerance between the two structures of a component, the processing technology adopted is generally to process the first structure on the bad body of the component, and then process the second structure based on the first structure. To shorten the dimensional chain and reduce the dimensional error between structures. The specific content of this processing technology is illustrated below with a specific example. [0003] ...

Problems solved by technology

[0006]Although the above-mentioned processing technology can improve the machining accuracy of parts and machining efficiency, in some cases, it is still difficult to give full play to the performance of the machine tool for some small machine tools Processing function

Please refer to figure 2 , the maximum moving distance of the table 300 relative to the spindle 500 in the X direction is L0, when the distance L between the hole 100 and the hole 200 of the component is less than L0, the boring machine can meet the needs of machining; however, in the component When the distance L between the hole 100 and the hole 200 is greater than L0, that is, when machining large-distance structural parts, when boring the hole 200, the center line of the hole 100 cannot be used as the processing reference, so the parts need to be Move an appropriate distance relative to the worktable 300, so that it is necessary to determine other machining references to bore the hole 200, and control the dimensional tolerance between the hole 100 and the hole 200 through the dimensional chain formed by multiple dimensional rings; in order to meet the processing needs, It is necessary to increase the process flow and increase the control of the error of each dimension ring, which will lead to an increase in the processing cost of the parts and a decrease in the processing efficiency of the parts

In addition, in the field of mechanical manufacturing and processing, it is very common to obtain parts blanks by flame cutting; for parts blanks formed from thick plates, it is necessary to reserve appropriate machining allowances to ensure the final size of parts; in this In this case, the machining datum cannot be determined on the outline of the component, even if the machining datum is barely determined, it is difficult to meet the machining size requirements between the hole 100 and the hole 200

[0007]The above problems not only exist in the case of ensuring the machining dimensional accuracy between holes, but also in the processing of other large-distance structural parts; for example, in When ensuring the dimensional tolerance between holes and grooves, grooves and grooves, there are also the same problems; similarly, the above technical problems not only exist in the boring machine process, but also in the drilling machine or other processing equipment.
