Vertical CNC machining center and horizontal machining center are common machining center classification. Under the condition of the same processing stroke, the vertical machining center is superior to the horizontal machining center in terms of price preference or extensive use. And horizontal machining is a kind of can realize multi-axis linkage of high-end CNC machine tool, widely used in automotive, aerospace, military industry in the field of mechanical processing of all kinds of complex components, falling for machine tool thermal deformation, improve the machining accuracy of machine tool manufacturers has been committed to lowering the temperature rise of the machine tool parts and the temperature difference, chip as an important heat source in machining process, to achieve its rapid rule out of machine tool is the key to solve the above problems, through the different base structure, realize the chip out of machine tool is an important method. Chenghai xiaobian summary of the existing horizontal machining center base, there are two structures:
Base structure: (1) the base of the Z axis drive (4), open two throughout the entire base square cavity (2) (3), the spiral chip removal device (5) (6) put in the cavity, the structure, exfoliation and chip space is little, the cutting heat within the narrow narrow clearance channels, conduction through the metal piece toward the base, and not conducive to large flow cooling cutting fluid backflow.
Base structure: in the processing side of the rear of the base (1), a large half-cut cavity (2) is set, and the broadened chain-plate chip eliminator (5) is placed in the cavity (2). On in front of the base (1) the processing side, the two spiral chip removal device (3) (4), will not scattered scraps import chain plate processing side splash of chip removal device (5), the structure, compared with the former structure, improve the machine tool chip removal ability, realize the processing side chip and the base of the cutting fluid quickly ruled out, however, more than the combination of chip removal device and the base (1) before and after the internal staircase design, increased the complexity of the structure and the difficulty of the machine tool protection design, manufacture and maintenance, the processing side, flying chip will still cutting heat conduction through the chip removal device and other metal parts toward the base.
Horizontal through the central drive machine bed structure
Including: X axis base, Z axis base, Z axis guide rail left support body, Z axis guide rail right support body, bridge type cross support, processing side chip channel, non-processing side chip channel, all through the base cavity, Z axis drive, Z axis drive installation body and chain-plate chip eliminator. Horizontal through the central drive machine bed structure, through the innovation of the structure to block the cutting heat to the base of the conduction and large flow of cutting fluid backflow, reduce the temperature of the base in the process of machine tool and other parts of the temperature difference, reduce the thermal deformation of the base, ensure the machine tool processing accuracy.
Designed to
This technology is to provide: a horizontal structure full throughout the central drive of machine tool base, realize pneumatic tool carrier locking and loosening, by servo motor and synchronous belt wheel head accurate tool change, has reliable performance, accurate positioning, compact structure and high transfer speed, low noise, the price is low wait for an advantage, at the same time on the application and popularization of small CNC machine bed has a broad market prospect.
To solve the above technical problems, the following technical solutions are adopted:
It includes: X axis base, Z axis base, Z axis guide rail left support body, Z axis guide rail right support body, bridge type cross support, processing side chip channel, non-processing side chip channel, all through the base cavity, Z axis drive, Z axis drive installation body and chain-plate chip eliminator.
Described above mentioned in the second cross to the X axis base areas for processing side area, between the above mentioned in the second cross to the area between the Z axis at the bottom of the base for the processing of the lateral area, referred to cross with the above mentioned in X axis between the base and cross arm and described in the second set above processing side exfoliation somewhat between cross channel, described the third cross between mentioned at the bottom of the Z axis base set above the exfoliation processing side channel.
Described the Z axis driver installation body the upper part of the setup described in the second cross arm and described the third on mentioned in the bottom of the Z axis driver installation body is set on the bottom of the Z axis base, described in the above mentioned in the Z axis driver Settings in the Z axis driver installed on the body, as described in chip removal device at one end of the chain plate described throughout the whole through the base described within the cavity and extends to the outside of the Z axis base.
