Abstract
The invention discloses a drilling fixture, and relates to the field of mechanical machining, in particular to the drilling fixture. The drilling fixture comprises a base arranged on a workbench, the base is a column with a boss, the center of the base is provided with a stepped through hole, and a bearing is arranged at a stepped position of the stepped through hole; a pedestal is connected to the upper end of the base and provided with a cylindrical protrusion, and the protrusion is matched with the bearing in the stepped through hole in the base; a three-jaw chuck is connected to the pedestal, the outer side of the three-jaw chuck is further provided with a base plate, the height of the base plate is adjustable, and the upper end of the three-jaw chuck is further provided with a grooving pressing plate part. According to the drilling fixture, the structure is simple, the machining efficiency can be improved, the machining precision is ensured, and the corresponding base plate can be replaced according to reference diameters and clamping heights of different workpieces; when different types of workpieces are replaced, only the initial workpiece needs to be subjected to tool setting, then, a drill press spindle and the fixture are fixed, and tool setting does not need to be conducted on all the workpieces; the labor intensity of workers is relieved, and the application range is wide.
Description
Technical field
The present invention relates to field of machining, be specifically related to boring grab.
Background technology
The plate-like class part such as flange, end cap is common part in machining industry, and flange, end cover part shape and specification are varied, and material mostly is steel part or foundry goods class. This type of part mostly is and exposes part, it is desirable to good looking appearance, requires have interchangeability when using simultaneously, namely requires that the bolt hole position of each part is wanted accurately. This some holes need to be processed with common vertical type rocker arm drilling machine, and due to each part shape different sizes, and batch is little, so can be competent at the location of major part part, clamping work without unified boring grab.
Traditional hole forming method is: turning blank molding one platform centering one is rule dotting punch one drilling machine clamping a pair cutter one boring, and this method is suitable for single hole processing, and production efficiency is low, and has to pass through crossed process before boring. Owing to plate-like class part all has centre bore, bad alignment point, therefore line work is considerably complicated, if number of parts is few and needs renewal part, then needs frequent line, changes fixture etc., greatly reduce production efficiency. In the course of processing in hole, depending operator's eyesight alone to cutter, error is bigger, it is easy to cause calibration inaccuracy, it is impossible to exchange.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of mechanism simple, can improve working (machining) efficiency, it is ensured that machining accuracy, boring grab applied widely.
Boring grab of the present invention, including the base arranged on the table, described base is the cylinder with boss, base center has a ladder hole, the ladder place of described ladder hole is provided with a bearing, base upper end is connected to a pedestal, described pedestal is provided with a cylindrical bump, this projection matches with the ladder hole middle (center) bearing on base, described pedestal is connected to scroll chuck, the outside of described scroll chuck is additionally provided with a backing plate, backing plate height adjustable, and the upper end of scroll chuck is additionally provided with slotted pressure plate parts.
Preferably, workbench being additionally provided with some clamping devices, described clamping device is handle type self clamping device.
Preferably, workbench being provided with three clamping devices, described clamping device is positioned on same circumference, and the center of circle of this circle overlaps with the center of circle, face, base top.
Preferably, base top excircle face nailing has a small dial, and is furnished with pointer, for indicating the circumference number of degrees on pedestal, and 20 evenly divided lines uniform on graduated disc.
Preferably, scroll chuck and pedestal adopt seam location and tolerance H7/g6.
Present configuration is simple, can improve working (machining) efficiency, it is ensured that machining accuracy, according to the circle-dividing diameter of different workpieces and clamping height, can change corresponding backing plate; When changing dissimilar workpiece, only initial workpiece workpiece need to be carried out cutter, and drill press spindle and fixture are fixed, it is not necessary to all workpiece be carried out to cutter, reduce labor strength, applied widely.

Fig. 1 is boring grab structural representation.
Accompanying drawing labelling: 1-base, 2-bearing, 3-pedestal, 4-scroll chuck, 5-slotted pressure plate parts, 6-workpiece, 7-backing plate, 8-clamping device, 9-workbench.
Detailed description of the invention
Boring grab of the present invention, including the base being arranged on workbench 9, described base 1 is the cylinder with boss, base 1 center has a ladder hole, the ladder place of described ladder hole is provided with a bearing 2, base 1 upper end is connected to a pedestal 3, described pedestal 3 is provided with a cylindrical bump, this projection matches with the bearing 2 in the ladder hole on base 1, described pedestal 3 is connected to scroll chuck 4, the outside of described scroll chuck 4 is additionally provided with a backing plate 7, backing plate 7 height adjustable, and the upper end of scroll chuck 4 is additionally provided with slotted pressure plate parts 5. Being additionally provided with some clamping devices 8 on workbench 9, described clamping device 8 is handle type self clamping device. Being provided with three clamping devices 8 on workbench 9, described clamping device 8 is positioned on same circumference, and the center of circle of this circle overlaps with the center of circle, face, base 1 top. Base 1 top excircle face nailing has a small dial, and is furnished with pointer, for indicating the circumference number of degrees on pedestal 3,20 evenly divided lines uniform on graduated disc. Scroll chuck 4 and pedestal 3 adopt seam to position, and tolerance H7/g6.
During use, first by drawing, the position line in standardized hole, operator is fixed by bolts to clamp base 1 on Drilling machines bench workpiece 6, then pulls handle, utilizes clamping device 8 pedestal 3 and base 1 to be tightly fastened. Then with centre bore or seam, workpiece 6 is positioned mode scroll chuck 1 to clamp, select suitable backing plate 4, and backing plate 4 holding screw is reliably connected on pedestal 3, slotted pressure plate parts 5 are installed, tighten panel nut, workpiece 6 locating clip tight knot bundle. The record pedestal 3 circumference number of degrees indicated by base 1 pointer. Then the position according to first hole, suitably regulates the relative position of drill press spindle and fixture, makes drill bit be directed at the first Ge Kongwei center, and lock drill press spindle and fixture, finally starts drilling machine and starts boring. After processing a hole, release handle turning of work piece is to proper angle, then pulls handle locking pedestal 3, smoothly completes the processing in other hole.
