Abstract
The utility model discloses a drop -down formula clamping device for machining center relates to the machine -building field, relates to a clamping device who has processed the screwed work piece. A drop -down formula clamping device for machining center, is including being fixed with the base of locating support seat, the locating support seat on seted up the locating hole, still include the screw, cross cab apron, locating pin and clamp plate, the screw with wait to process the screw -thread fit of work piece, cross on the cab apron counter bore that processing has the via hole through the locating pin and is used for the screw, the cab apron of crossing compress tightly through the clamp plate and fix the seat at locating support. The utility model discloses simple structure, convenient operation not only can shorten cutter length, has improved cutting precision and machining efficiency moreover.
Description
Technical field
This utility model relates to mechanical manufacturing field, relates to a kind of clamping device having processed threaded workpiece, is specifically related to a kind of pull-down clamping device for machining center.
Background technology
Grip device is to be used for fixing processing object in machine-building process, so as to occupy correct position, to accept construction or the device of detection.On lathe during processing work, drawing specifies in order to make the surface of workpiece to reach dimensions, geometry and with the technology requirements such as the relative-position error on other surfaces, workpiece must be positioned before processing, clip.
In the course of processing, owing to Workpiece structure limits, especially larger-size workpiece is adding man-hour, in order to be fixedly positioning by workpiece, be usually the surrounding at workpiece and sets up column, then pass through pressing plate and fasten, and then uses Tool in Milling processing.But, owing to being provided with the column for compressing at machined surface, this will increase the length of process tool to a certain extent, thus adding the cost of charp tool, and due to the growth of tool length, cutting parameter can be made to reduce, thus it is low to reduce working (machining) efficiency, the loss percentage of cutter also can increase, and also affects machining accuracy simultaneously.
In order to solve the drawbacks described above that existing machine tool clamping device exists, this utility model have developed one and is particularly suited for large volume, and bottom has processed the Workpiece clamping device of screwed hole.
Summary of the invention
The purpose of this utility model is to provide a kind of pull-down clamping device for machining center.
This utility model is achieved through the following technical solutions:
A kind of pull-down clamping device for machining center, including the base being fixed with positioning support bearing, described positioning support bearing offers hole, location；Also include screw, rebound, alignment pin and pressing plate, described screw and the threaded engagement of workpiece to be processed, described rebound is processed the via having by alignment pin and the counterbore for screw；Described rebound is pressed abd fixed on positioning support bearing by pressing plate.
Further, described base being symmetrically arranged with two positioning support bearings, two rebounds are fixed in positioning support bearing respectively through two pressing plates.
Being also equipped with rest pad on described base, rest pad is arranged on base, and workpiece is played a supportive role.
During work, first with screw, the workpiece processing screwed hole is combined with rebound, then place it in positioning support bearing, finally by pressing plate, rebound is fastened in positioning support bearing, thus being fixed on base by Work-sheet pressing, cutter is then used to carry out machining.Comparing existing lathe, this utility model can omit four big columns, thus shortening the length of cutter, being possible not only to reduce the loss percentage of cutter, and can improve cutting parameter and working (machining) efficiency, improve machining accuracy, save the clamping time in line simultaneously.
In sum, this utility model simple in construction, easy to operate, it is possible not only to shorten tool length, and improves cutting precision and working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use schematic diagram of the present utility model；
In figure: 1-base, 2-positioning support bearing, 3-position hole, 4-alignment pin, 5-rebound, 6-pressing plate, 7-screw, 8-workpiece, 9-rest pad.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
A kind of pull-down clamping device for machining center as shown in Figure 1, including the base 1 being fixed with positioning support bearing 2, described positioning support bearing 2 offers hole 3, location；Also including screw 7, rebound 5, alignment pin 4 and pressing plate 6, described screw 7 coordinates with workpiece screwed hole, and on described rebound 5, processing has the via by alignment pin 4, with the counterbore for screw 7；Described rebound 5 is fixed in positioning support bearing 2 by pressing plate 6.
During use, as shown in Figure 2, workpiece 8 is combined by bolt 7 and rebound 5, then positioning support bearing 2 is placed it in, finally by pressing plate 6, rebound 5 is fastened in positioning support bearing 2, thus being pressed abd fixed on base 1 by workpiece 8, workpiece is played a supportive role by the rest pad 9 being arranged on base 1 centre position.
