Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic top view of the structure of FIG. 1;
in the figure, a clamping disc 1, a vertical positioning plate 2, an oval positioning hole 21, a mounting hole 22, a transverse positioning plate 3, a placing hole 30, a limiting bolt 4, a pressing assembly 5, a positioning rod 51, a locking screw 52, a locking nut 53, a pressing block 54, a triangular rib plate 6, a connecting block 7 and a limiting block 8.
Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1-2, the utility model provides an irregular part clamping tool, including a clamping disc 1, a clamping seat is detachably installed on the clamping disc 1, the clamping seat includes a vertical positioning plate 2 installed on the clamping disc 1 and a transverse positioning plate 3 vertically fixedly connected with the vertical positioning plate 2, an elliptical positioning hole 21 is opened on the vertical positioning plate 2, and a limit bolt 4 positioned at two sides of the elliptical positioning hole 21 is connected with the vertical positioning plate 2 by screw thread; a placing hole 30 for positioning is formed in the transverse positioning plate 3, in order to match with a step shaft structure on a sliding component, the placing hole 30 comprises three-stage step holes with diameters decreasing from top to bottom, and a pressing assembly 5 for matching and pressing the placing hole 30 is further arranged on the transverse positioning plate 3; after the sliding part is limited through the oval positioning hole 21 and the placing hole 30, the sliding part is locked by locking the two limiting bolts 4, and then the whole sliding part is pressed tightly through the pressing component 5, so that the sliding part is prevented from moving in the machining process. The chuck disk 1 is mounted on a three-jaw chuck and then positioned on a lathe, so that irregular parts can be machined on the lathe.
The pressing assembly 5 comprises two positioning rods 51 which are vertically and fixedly connected to the transverse positioning plate 3 and are symmetrical relative to the placing hole 30, and locking screw rods 52 which extend upwards are fixedly connected to the two positioning rods 51, and pressing blocks 54 are sleeved on the two locking screw rods 52 and locked through locking nuts 53; the position of the pressing block 54 is defined by rotating the lock nut 53 after pressing the parts by sliding the pressing block 54 downward on the two lock screws 52 so that the positions of the parts do not move.
Meanwhile, in order to increase the connection stability between the vertical positioning plate 2 and the transverse positioning plate 3, two triangular rib plates 6 located at the edge positions of the transverse positioning plate 3 are fixedly connected between the vertical positioning plate 2 and the transverse positioning plate 3, so that the stability of the whole structure is improved.
The connecting block 7 is fixedly connected between the adjacent triangular rib plates 6 and the positioning rod 51, so that the installation state of the positioning rod 51 is further limited, and the structural stability of the positioning rod 51 after pressure bearing is ensured.
In order to limit the longitudinal movement of the vertical positioning plate 2 and ensure that the axis after the clamping of the parts is aligned with the axis of the lathe, two limiting blocks 8 used for limiting the upward movement of the vertical positioning plate 2 are installed on the clamping disc 1, and the two limiting blocks 8 are installed through bolts, so that the vertical positioning plate 2 is conveniently limited and locked after the installation position is determined.
Meanwhile, the vertical positioning plate 2 is provided with strip-shaped mounting holes 22 which are positioned around the oval positioning holes 21, so that fine adjustment of the position of the vertical positioning plate 2 when the vertical positioning plate is mounted on the clamping disc 1 is facilitated.
