Abstract
The invention discloses a cotter pin hole drill jig which is characterized in that a base is connected with a support by a bolt; the support is welded with a bearing pedestal; a shaft is inserted into the bearing; one end of the shaft is pressed with a positioning sleeve by a nut; the other end of the shaft is provided with an opening gasket; the middle of the shaft is provided with a plurality of semicircular concave holes; the upper end surface of the bearing pedestal is connected with a bushing plate by the bolt; and one end of the bushing plate is provided with a drill bushing. According to the above arrangement, the cotter pin hole drill jig is cooperated with a bench drilling machine, and the angle size of a workpiece is guaranteed to position by a tool to drill the cotter pin hole. The cotter pin hole drill jig is convenient to clamp and position, the accuracy of machining size is improved, the labor intensity of workers is lowered, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of manufacturing auto parts and components and use frock, is a kind of cotter-pin hold drill jig specifically.
Background technology
My company's processing structure joint adopts manual line operation when boring cotter-pin hold, working (machining) efficiency is low, and Angular Dimension can not accurately hold, when producing in the busy season satisfied not production requirement.
Summary of the invention
The object of the invention is the cotter-pin hold drill jig that provides a kind of simple in structure, easy to use.
To achieve these goals, the present invention is connected with bearing through bolt on base, on bearing, is welded with bearing block; Two ends at bearing block respectively are inlaid with bearing, in bearing, are interspersed with axle, and an end of axle has positioning sleeve through the nut pressing; The other end at axle is provided with open washer; Be provided with a plurality of semicircle shrinkage pools in the middle part of axle, semicircle shrinkage pool is corresponding with steel ball and spring, is provided with through bolt in the upper surface of bearing block and is connected with bushing plate; End at bushing plate is provided with drill bushing, and drill bushing is corresponding with workpiece.
Through above setting, the present invention is cooperated with bench drill, with the location of frock assurance workpiece angle size, bore cotter-pin hold.Make things convenient for the clamping location, improved the accuracy of processing dimension, reduced working strength of workers, improved production efficiency.
Description of drawings
Combine accompanying drawing that the present invention is further specified at present.
Fig. 1 is a structural representation of the present invention.
Among the figure 1, positioning sleeve, 2, drill bushing, 3, bushing plate, 4, axle, 5, open washer, 6, bearing block, 7, bearing, 8, base, 9, bearing, 10, workpiece, 11, drill bit, 12, steel ball, 13, spring.
The specific embodiment
As shown in Figure 1, the present invention is connected with bearing 7 through bolt on base 8, on bearing 7, is welded with bearing block 6; Two ends at bearing block 6 respectively are inlaid with bearing 9, in bearing, are interspersed with axle 4, and an end of axle 4 has positioning sleeve 1 through the nut pressing; The other end at axle 4 is provided with open washer 5; Be provided with a plurality of semicircle shrinkage pools in the middle part of axle 4, semicircle shrinkage pool is corresponding with steel ball 12 and spring 13, is provided with through bolt in the upper surface of bearing block 6 and is connected with bushing plate 3; End at bushing plate 3 is provided with drill bushing 2, and drill bushing 2 is corresponding with workpiece 10.
Through above setting; The present invention is cooperated with bench drill, and turning cylinder 4 makes steel ball 12 corresponding with the semicircle shrinkage pool of the middle part of axle 4; Lock opening packing ring 5; Bore cotter-pin hold with regard to 11 pairs of workpiece 10 of available drill bit, each turning cylinder 4 can accurately and simply guarantee the cotter-pin hold Angular Dimension.
