The utility model content
In view of this, the purpose of this utility model is to provide a kind of parallel string hole processing tool, and it can guarantee the positioning accuracy of workpiece, clamping workpiece is placed steadily, clamping is easy, can improve the parallel string of workpiece hole machining accuracy and guarantee the crudy uniformity, can solve the shortcoming that existing angle bar frock exists.
The parallel string of the utility model hole processing tool, comprise pedestal, be provided with the knife bar supporting arrangement on described pedestal, described knife bar supporting arrangement comprises two supporting bases that are separately positioned on the pedestal two ends, is provided with the bearing hole of coaxial and axis horizontal mutually on described two supporting bases.
Further, be provided with the knife bar cover in the bearing hole of described two supporting bases;
Further, also comprise knife bar, the two ends of described knife bar are arranged at respectively in knife bar cover on two supporting bases;
Further, also be provided with the vertical knife bar via hole of axis on described pedestal between two supporting bases, in described knife bar via hole, the knife bar stop collar be set;
Further, described supporting base is connected with pedestal by screw;
Further, also be provided with Working piece positioning device and workpiece pressuring clamping device on described pedestal, described Working piece positioning device comprise the location key seat that is fixed by screws on pedestal and with the alignment pin of location key seat threaded engagement; Described workpiece pressuring clamping device comprises the screw rod that coordinates with base thread, be coated at screw rod and the pressing plate that can slide up and down along screw rod, be coated at screw rod and upper end withstands on the spring on the pressing plate bottom surface and coordinates with base thread and withstand on push rod on the pressing back-end bottom surface.
The beneficial effects of the utility model: the parallel string of the utility model hole processing tool, workpiece lies against on pedestal, and workpiece is placed steadily, convenient mounting and clamping is reliable, workpiece can not move under Action of Gravity Field, the clamping high conformity, thus can guarantee the uniformity of the parallel string of workpiece hole crudy; Boring bar is placed on the supporting base of this frock in process simultaneously, can strengthen the rigidity of boring bar, and the boring cutter amplitude of fluctuation is little, can improve machining accuracy.
Description of drawings
Fig. 1 is the front view of this parallel string hole processing tool;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the parallel string of the present embodiment hole processing tool comprises pedestal 1, is provided with the knife bar supporting arrangement on described pedestal 1, described knife bar supporting arrangement comprises two supporting bases 2 that are separately positioned on pedestal 1 two ends, is provided with the bearing hole of coaxial and axis horizontal mutually on described two supporting bases 2.
The parallel string of the present embodiment hole processing tool, workpiece lies against on pedestal 1, and workpiece is placed steadily, and convenient mounting and clamping is reliable, and workpiece can not move under Action of Gravity Field, the clamping high conformity, thus can guarantee the uniformity of workpiece crudy; Simultaneously boring bar is placed in the bearing hole of supporting base 2 of this frock in process, can strengthen the rigidity of boring bar, and the boring cutter amplitude of fluctuation is little, can improve the parallel string of workpiece hole machining accuracy.
As the improvement to the present embodiment, be provided with knife bar cover 3 in the bearing hole of described two supporting bases 2, in concrete enforcement, knife bar cover 3 is replaceable, and knife bar cover 3 diameter of bores can have different specifications, are convenient to coordinate with the knife bar of different-diameter, and versatility is good.
As the improvement to the present embodiment, originally parallel string hole processing tool also comprises knife bar 4, and the knife bar that the two ends of described knife bar 4 are arranged at respectively on two supporting bases 2 overlaps in 3; In concrete enforcement, exist boring machine self knife bar can not satisfy the situation of processing request, the knife bar 4 that arranges in this frock, it can directly be connected with boring spindle, can realize that to the different workpieces bore hole, versatility is good.
As the improvement to the present embodiment, also be provided with the vertical knife bar via hole 5 of axis on described pedestal 1 between two supporting bases 2, in described knife bar via hole 5, knife bar stop collar 6 is set, knife bar via hole 5 structures make this frock can be used on vertical boring mill, the processing of realization to vertical hole, knife bar stop collar 6 can limit the amplitude of fluctuation of knife bar, can improve the bore hole precision.
As the improvement to the present embodiment, described supporting base 2 is connected connection with pedestal by screw, can realize can satisfying the bore hole requirement of different workpieces on the diverse location of supporting base 2 is fixing and pedestal 1 many group screw holes can be set on pedestal 1.
As the improvement to the present embodiment, also be provided with Working piece positioning device and workpiece pressuring clamping device on described pedestal 1, described Working piece positioning device comprise the location key seat 7 that is fixed by screws on pedestal 1 and with the alignment pin 8 of location key seat 7 threaded engagement; Described workpiece pressuring clamping device comprises with the screw rod 9 of pedestal 1 threaded engagement, be coated at screw rod 9 and the pressing plate 10 that can slide up and down along screw rod 9, be coated at screw rod 9 and upper end withstand on pressing plate 10 bottom surfaces spring 11 and with pedestal 1 threaded engagement and withstand on push rod 12 on pressing plate 10 bottom surfaces, rear end; This structure Working piece positioning device and workpiece pressuring clamping device are applicable to most box parts, highly versatile, and certainly in different embodiments, Working piece positioning device and workpiece pressuring clamping device also can adopt other structures.
