Abstract

A counter-pull type working platen device for a milling machine comprises four uprights (1), a counter-pull type baseplate (5) and screws A. The uprights (1) are fixedly arranged at four corners of the counter-pull type baseplate (5) through screws B (7). A counter-pull type table face (3) is fixedly arranged at the tops of the uprights. A workpiece (2) is arranged on the counter-pull type table face (3). Threaded blind holes for processing are formed in the back of the workpiece (2). The counter-pull type working platen device is simple in structure and convenient to operate, conventional fixing modes are simplified, an area for cutting of a cutter is enabled to be clean and free of redundant barriers, a path for cutting of the cutter is optimized, and technological processes and step numbers can be reduced to some extent; cutter collision caused by interference of the cutter, a compress plate, a fixing screw, a fixing nut and the like is avoided, and processing quality and working efficiency are improved.

Description

technical field

[0001] The invention relates to the field of mechanical processing, in particular to a reverse pull-type worktable device for a milling machine. Background technique

[0002] During the machining process, especially in the milling process of the three-axis, four-axis machining center or ordinary milling machine tool, the fixing and positioning of the workpiece are carried out on the worktable. The commonly used workbench style is a flat steel plate or aluminum plate, and T-shaped slots, equidistant threaded holes and appropriate pin holes are processed on the steel plate or aluminum plate to facilitate the fixing and positioning of the work. When the tabletop working in this way fixes the workpiece, the bottom surface of the workpiece is in contact with the worktable, and is fixed by top pressure or side pressure. Because this kind of fixing method needs to increase pressing plate, bolt etc. on the top surface of work or around. The cutting path of the tool...

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] Referring to the accompanying drawings, a reverse pull-type workbench device for a milling machine includes a column 1, a reverse pull-type bottom plate 5, and a screw A, and is characterized in that: the four corners of the reverse pull-type bottom plate 5 are provided with screws B7 Four columns 1 are fixedly arranged, and the top of the column 1 is fixedly provided with a pull-back table top 3 , a workpiece 2 is arranged on the pull-back table top 3 , and a threaded blind hole for process is arranged on the reverse side of the workpiece 2 . The anti-pull bottom plate 5 is provided with a counterbore 6 matching the workbench of the milling machine. During specific implementation, the height of the column 1 will ensure that there is enough space to operate the fastening wrench below the reverse-pull table top 3, and the reverse-pull table 3 has a certain thickness, ...
