Description
Technical field
The utility model relates to a kind of anchor clamps of metal working machine tool, especially the clamping device that adopts during two of boring hydraulic gear pump side plate endoporus.
Background technology
Hydraulic gear pump side plate (Fig. 3, shown in Figure 4) is the vitals of hydraulic gear pump; Because these parts cooperate with the rotating shaft of pump gear, thereby to position, the dimension precision requirement strictness of two endoporus (shown in D1, the D2), needs employing boring process.
Conventional boring processing mode is to fix with plain clamp after being installed in gear pump side-plank on the work top, and boring cutter carries out boring to two endoporus of gear pump side-plank respectively then; After the process finishing, manually unclamp anchor clamps, take off gear pump side-plank.This processing mode operating efficiency is not high, and the clamping dynamics of plain clamp is difficult to grasp, and side plate may become flexible adding man-hour, causes the position of two endoporus and dimensional accuracy not to reach requirement.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of gear pump side-plank endoporus boring clamping device is provided, and this boring clamping device should be able to effectively improve the boring precision, and has the high characteristics of working (machining) efficiency.
The technical scheme that the utility model provides is: hydraulic gear pump side plate endoporus boring clamping device comprises a horizontally disposed workbench; This workbench is provided with positioner; It is characterized in that: also be provided with lever lock device on the described workbench, comprise the support of a vertical layout, the top of this support is hinged with a lever; Described lever lock device also comprises a vertically arranged pressing plate, and this pressing plate is connected by connecting plate with an end of described lever, and the two ends, the left and right sides of pressing plate respectively are provided with being used for a guide plate to this pressing plate guiding that is arranged vertically on described support; The other end and the driving mechanism of lever are hinged.
The lower end of described pressing plate is shaped on two arc-shaped concaves that match with excircle of workpiece.
Respectively being provided with one on the described guide plate matches with described pressing plate and to merge slide rail to the pressing plate guiding.
The connected mode of described pressing plate and described connecting plate is hinged.
Described driving mechanism is a cylinder; The piston rod of this cylinder and described lever are hinged, and the other end of cylinder is hinged on the described support.
Described positioner comprises block and the locating piece that is arranged on the workbench.
Operation principle of the present utility model is: workpiece (one or more) is installed in (being positioned on the locating piece of workpiece middle part, the workpiece left end is near block) on the workbench; Open cylinder then, promoting the hinged end of lever and cylinder moves upward, according to lever principle, lever can apply downward pressure to pressing plate by connecting plate, make pressing plate move downward until workpiece pressing (this moment, the arc-shaped concave and the excircle of workpiece face of pressing plate fitted tightly) along the slide rail of guide plate, borer begins workpiece is processed; After the process finishing, the piston rod of cylinder shrinks, and pressure plare rises, and workpiece can be taken off.
The beneficial effects of the utility model are: because the clamping device that the utility model provides is provided with cylinder, add man-hour, can regulate pressing plate to the workpiece applied pressure, the automaticity height by the telescopic level of regulating cylinder piston rod; And the pressure plare lower end is shaped on two spill cambered surfaces that match with excircle of workpiece, makes when clamping workpiece stressed evenly and stable, and workpiece can not become flexible during boring, can effectively improve the machining accuracy of endoporus, has significantly improved product quality; In addition, this clamps device can clamp the polylith side plate simultaneously, and boring cutter is processed it simultaneously, has improved production efficiency greatly.

The specific embodiment
As shown in Figure 1 and Figure 2, hydraulic gear pump side plate endoporus boring clamping device comprises a horizontally disposed workbench 9; Described workbench is provided with lever lock device, the support 1 that comprises a vertical layout, the top of this support are hinged with a lever 2, and an end of lever is hinged with driving mechanism, the other end is hinged with a plate 4, and the lower end of this connecting plate and a vertically arranged pressing plate 3 are hinged; The two ends, the left and right sides of described pressing plate respectively are provided with a guide plate 5 that is arranged vertically on described support 1, guide plate be provided with described pressing plate match merge to the pressing plate guiding slide rail.
The lower end of described pressing plate 3 is shaped on two spill cambered surfaces that match with excircle of workpiece, can fit tightly with excircle of workpiece when compressing; Described driving mechanism is a cylinder 10; The piston rod 10-1 and the described lever 2 of this cylinder are hinged, and the other end of cylinder is hinged on the described support 1.
Also be provided with positioner on the described workbench, comprise a block 6 (clean and tidy for making picture, block 6 omits and do not draw among Fig. 2) and locating piece 7; Described block is arranged on the left end (also can be arranged on right-hand member, determine according to actual conditions) of workpiece 8; The upper surface of described locating piece is made the arc-shaped protrusions (radian of locating piece and height can be determined according to actual conditions) that matches with described workpiece middle part, can position workpiece with baffle plate; Described borer 11 is installed on the frame.
The power of the thickness of pressing plate, support height, lever length and driving cylinder can be determined according to actual conditions.The also available employing hydraulic jack of described drive unit; Described cylinder, the equal buyable of hydraulic jack obtain.
