Detailed Description
For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.
Example 1
As shown in fig. 2, the present invention is a schematic view of the whole structure of the clamping device for machining the semicircular workpiece of the lathe. This clamping device includes:
the chuck 30 is provided with four clamping seats 20 which are uniformly distributed on a circumference at equal circumferential angles on the chuck 30.
A semicircular auxiliary clamping plate 40 (shown in combination with fig. 3) includes a first side wall 41 and a second side wall 42, the first side wall 41 is a diameter side corresponding to the semicircular auxiliary clamping plate, and the second side wall 42 is a semicircular arc side corresponding to the semicircular auxiliary clamping plate.
A semicircular material to be machined 50 abuts with its diameter side against the first side wall 41 of the semicircular auxiliary clamping plate 40, and the four clamping seats 20 surround and abut against the second side wall 42 of the semicircular auxiliary clamping plate 40 and the semicircular arc side of the semicircular material to be machined 50, thereby fixing the semicircular material to be machined 50 on the chuck 30 so that a lathe milling cutter performs a cutting process on the middle of the semicircular material to be machined 50. As shown in fig. 2, the present embodiment requires machining to obtain a semi-circular workpiece.
Referring to fig. 3, a schematic view of the semicircular auxiliary clamping plate 40 of embodiment 1 is shown. The first side wall 41 of the semicircular auxiliary clamping plate 40 forms an extension wall A along the thickness direction thereof, so that the semicircular auxiliary clamping plate 40 has an L-shaped cross section. Therefore, the contact area of the first side wall 41 of the semicircular auxiliary clamping plate 40 and the semicircular material to be processed 50 which are actually abutted to each other is increased, and the semicircular material to be processed is prevented from being laterally turned and shifted due to extrusion and losing the clamping and positioning effects.
Preferably, the semicircular auxiliary clamping plate 40 is designed such that its diameter is equivalent to the diameter of the semicircular material to be processed 50 by not more than ± 4%.
Further, the number of the cartridges 20 is 4, 6 or 8, and is equally distributed circumferentially on one circumference, and so on.
Further, the cartridge 20 can be moved in a radial direction of the chuck, finely adjusted in position, and positioned. Therefore, the processing method can meet the processing requirements of semicircular workpieces with different diameters.
Further, as shown in fig. 4, a structural schematic diagram of the card socket of embodiment 1 is shown. Each clamping seat 20 comprises a clamping surface 22, and the clamping surface 22 is used for abutting against the second side wall 42 of the semicircular auxiliary clamping plate 40 and the semicircular arc side of the semicircular material to be processed 50 so as to clamp the semicircular auxiliary clamping plate 40 and the semicircular material to be processed 50 towards the middle. Preferably, the clamping surface 22 is provided with an adjustable clamping bolt 23, and one end of the clamping bolt 23 abuts on the semicircular auxiliary clamping plate 40 and the semicircular material to be processed 50.
As shown in fig. 5, the process of using the clamping device to fix the semicircular workpiece to be processed 50 and process the semicircular workpiece is as follows:
(1) the semicircular material to be processed 50 is fixed by the clamping device, and the clamping bolt 23 is adjusted to enable the inner end of the clamping bolt to abut against the peripheral wall surfaces of the semicircular material to be processed 50 and the semicircular auxiliary clamping plate 40.
(2) The lower cutting amount of the milling cutter is adjusted, so that the height H1 of the semicircular auxiliary clamping plate 40 is less than the height H3 of the semicircular material to be processed 50, namely the height H2 of the processing surface, and the height H1 of the semicircular auxiliary clamping plate 40 is less than the height H2 of the processing surface. And starting the lathe to enable the milling cutter to make a round cutting movement.
(3) After finishing, turning over the semicircular material to be processed 50, fixing the semicircular material to be processed according to the mode in the step (1), and starting the lathe to enable the milling cutter to perform circle cutting and rounding movement again.
Because H1 < H2, the milling cutter can not cut the semicircular auxiliary clamping plate 40 when cutting and rounding for the first time; and because H1 < H3-H2, the milling cutter can not cut the semicircular auxiliary clamping plate 40 when cutting and rounding for the second time. After the round is cut twice, the semicircular material to be processed 50 is processed into a semicircular workpiece.
It should be noted that, the clamping device of the present invention is not limited to the processing of the semicircular workpiece, and can also be used for processing other semicircular workpieces, such as the processing of cutting and rounding the semicircular workpiece to be processed.
