Detailed Description
For a better understanding of the contents, features and effects of the present invention, the following embodiments will be illustrated in detail with reference to the accompanying drawings. It should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereby.
A milling R groove frock of the special-shaped work piece, the inferior part of the special-shaped work piece 2 is a ladder-shaped base 11, the upper portion of the special-shaped work piece sets up the tubular member 12 vertically, and the middle part of the special-shaped work piece is made and penetrated the tubular member and work piece hole 13 of the ladder-shaped base axially; mill R groove 10 processing on the inclined plane of trapezoidal base both sides, its characterized in that: the R-shaped groove milling tool comprises a clamping seat 1, wherein a channel 7 for clamping and fixing the special-shaped workpiece is formed on the top surface of the clamping seat; the middle part of the channel is upwards protruded and positioned to support the special-shaped workpiece, and the two sides of the channel are downwards sunken and adjusted to be embedded and matched with cushion blocks supported on two opposite side walls of the special-shaped workpiece.
And a checking hole 9 is vertically formed in the middle of the channel, and a checking polished rod axially penetrates through the workpiece hole and is inserted into the checking hole so as to check the coaxiality of the checking hole and the workpiece hole.
Moreover, the cushion blocks comprise a flat cushion block 3, a first trapezoidal cushion block 5 and a second trapezoidal cushion block 6; the flat cushion block is embedded in a groove which is recessed downwards on one side of the channel; the second trapezoidal cushion block is adjusted and embedded in a groove which is recessed downwards on the other side of the channel, and an adjusting bolt 4 vertically penetrates through and is inserted into the second trapezoidal cushion block; the thread section of the adjusting bolt extends downwards and is in threaded connection with the inside of the clamping seat; the first trapezoidal cushion block is arranged between the second trapezoidal cushion block and the special-shaped workpiece.
And a limiting block 8 for limiting the sliding of the special-shaped workpiece along the extending direction of the channel is fixedly arranged on the plane which is convex upwards in the middle of the channel.
Furthermore, clamping planes 14 which are parallel to each other and clamped and fixed by the dividing plate bench clamp are symmetrically formed on the side wall of the clamping seat.
To more clearly illustrate the embodiments of the present invention, an example is provided below:
the utility model discloses a milling R groove frock of special-shaped workpiece, for guaranteeing that the error is controllable, need press from both sides earlier and adorn the location holder on graduated disk bench vice, should guarantee that the clamping face of clamp and the double-layered plane of dress of holder laminate completely, and the table surface of holder bottom surface and clamp laminates completely. Then positioning and clamping the special-shaped workpiece on the clamping seat, placing the flat plate cushion block, the first trapezoidal cushion block and the second trapezoidal cushion block in place in the groove channel before positioning the special-shaped workpiece, loosening the adjusting bolt, enabling the second trapezoidal cushion block to go upwards, and providing abdication for the special-shaped workpiece to enter between the flat plate cushion block and the first trapezoidal cushion block; when the special-shaped workpiece is positioned, the special-shaped workpiece is pushed into the channel in parallel from the opening of the channel above the clamping plane until one end of the special-shaped workpiece props against the limiting block, then the adjusting bolt is screwed to enable the second trapezoidal cushion block to move downwards, then the side wall of the second trapezoidal cushion block extrudes the first trapezoidal cushion block, and finally the special-shaped workpiece is clamped by the side wall of the first trapezoidal cushion block and the side wall of the flat cushion block in a matching manner.
After positioning is finished, the positioning precision needs to be calibrated, a check polished rod is inserted into a workpiece of the special-shaped workpiece in the air, if the polished rod can penetrate through a workpiece hole and is inserted to the bottommost end of the check hole, the check polished rod is ensured to be in place by observing scales on the check polished rod, and therefore the workpiece hole and the check hole are judged to be coaxial; if the inspection polished rod cannot be inserted into the bottommost end of the check hole, the workpiece hole and the check hole are not coaxial when the special-shaped workpiece is horizontally positioned, the clamping and positioning are determined to be inaccurate at the moment, the adjusting bolt needs to be unscrewed, foreign matters on the bottom surface of the special-shaped workpiece and the top surface of the channel are cleaned, and the special-shaped workpiece is clamped and positioned again until the check is passed.
