Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art that design, the technical scheme of the present invention are had more complete, accurate and deep reason
Solve, and contribute to its enforcement.
As shown in Figure 1 to Figure 3, the invention provides a kind of split plain bearing seat bolt hole processing clamping device, bag
Include base plate 1 and be arranged on base plate 1 and for the workpiece locating mechanism that bearing block is positioned, for the compression of compression axis bearing
Mechanism and for drill bit location boring detent mechanism.
Specifically, as shown in Figure 1 to Figure 3, base plate 1 is the rectangular flat of horizontal positioned, and the end face of base plate 1 is level
Face.Workpiece locating mechanism includes the location-plate 8 being fixedly installed on the end face of base plate 1 and is vertically arranged at determining on location-plate 8
Position pin, the end face of location-plate 8 is the locating surface for contacting with bearing block, and this locating surface is the top face being positioned at base plate 1
And the horizontal plane paralleled with the end face of base plate 1.When bearing block is carried out Drilling operation, bearing block is positioned over location-plate 8
End face on, make the bottom surface of bearing block contact with the end face of location-plate 8, now the end face of bearing block is parallel with bottom surface flat
Face and for spell mutually with bearing cap and faying face, adding man-hour, processed on the end face of bearing block by drill bit and meet the requirements
Bolt hole.
As shown in Figure 1 to Figure 3, alignment pin is vertically arranged two on location-plate 8, the axis of two alignment pins and location-plate
The end face of 8 is perpendicular and extending above towards location-plate 8.In two alignment pins, one of them is circular alignment pin 10, another
Individual for diamond positioning pin 11, circular alignment pin 10 and diamond positioning pin 11 are to be staggeredly arranged and both are in and the length of base plate 1
Have between direction less than on the same straight line of 90 degree of angles, the bottom surface of bearing block is selected to have respectively and fits mutually with two alignment pins
The hole, location joined, arranges alignment pin more accurately reliable to ensure that bearing block adds location in man-hour.
The hold-down mechanism of this clamping device matches to compress bearing cap with workpiece locating mechanism, as shown in Figure 1 to Figure 3,
Hold-down mechanism includes the bearing 13 being vertically arranged on base plate 1, for bearing block being applied thrust and being positioned at above location-plate 8
Compressor arm 3 and be connected with bearing 13 and for compressor arm 3 being applied the pressing plate 7 of thrust.Compressor arm 3 is positioned at pressing plate 7
Lower section, compressor arm 3 is the most horizontal above location-plate 8, and compressor arm 3 is to embed bearing block when bearing block is applied thrust
In axis hole, pressing plate 7 length direction along compressor arm 3 arrange multiple, and compressor arm 3 is applied by multiple pressing plates 7 in various location
Thrust, improves the reliability compressed.
As shown in Figure 1 to Figure 3, as preferably, compressor arm 3 is round bar, and the diameter of compressor arm 3 is slightly less than bearing block end face
The diameter of center axis hole, compressor arm 3 embeds in the axis hole of bearing block, and bearing block is applied thrust.The length of compressor arm 3 is big
In the width of bearing block, and slightly larger than the width of base plate 1.When impaction state, the axis of compressor arm 3 and the width side of base plate 1
Paralleling to parallel and with axis hole axis, compressor arm 3 centre position in the longitudinal direction contacts with bearing block, compressor arm
The periphery of 3 keeps contacting with the inner headed face at bearing block axis hole, and in the center of bearing block, bearing block is applied thrust,
Make bearing block uniform force, and on bearing block, need the position of boring to be in the both sides of axis hole, circular alignment pin 10 and rhombus location
Pin 11 also lays respectively at the side of compressor arm 3.Further, since compressor arm 3 is by the inner circle at periphery and bearing block axis hole
Face contacts, and forms the linear contact lay of constant length, and contact surface is less, reduces compressor arm 3 and the abrasion of bearing block, and compression can
Lean on.
