Detailed Description

As shown in figure 1, the device consists of a support 1, an open thread cutting sleeve 2, a hand wheel sleeve 3 and a positioning pin 4.

The support 1 consists of a bottom plate and a vertical plate, and a through hole is arranged above the vertical plate.

The hand wheel sleeve 3 is matched with the open thread cutting sleeve 2 in a threaded connection mode.

The support 1 is responsible for the supporting action of the whole device.

The open thread cutting ferrule 2 is installed in the through hole above the support 1, and the open end of the open thread cutting ferrule 2 is inclined outwards by 3 degrees.

The positioning pin 4 is used for positioning the workpiece.

As shown in fig. 1, the main body is a support 1, and is formed by welding a bottom plate and a vertical plate. It can be fixed on a workbench of a workshop. The vertical plate of the support 1 is provided with a through hole, and an open thread cutting sleeve 2 matched with the vertical plate is arranged in the through hole.

One end of the open thread cutting sleeve 2 is inclined outwards in a 3-degree direction, and the other end is provided with threads.

The outer surface of the hand wheel sleeve is provided with 8 handles which are uniformly distributed and welded on the thread sleeve. The threads of the threaded sleeve are matched with the open threaded cutting sleeve 2. When the rotary body is rotated anticlockwise to the end face of the support, under the action of the reaction force, the open thread cutting sleeve 2 is driven to move towards the hand wheel sleeve, the open end of the open thread cutting sleeve is contracted, and then the rotary body workpiece can be fixed. The locating pin 4 is matched with a workpiece locating groove and is used for locating the workpiece in the open thread cutting sleeve 2 before the workpiece is assembled. After positioning, the hand wheel sleeve 3 can be rotated to position the workpiece.

Fig. 4 and 5 show the support of fig. 1, a three-quarter round steel block, and a round hole with one end round and the other end V-shaped is formed in the middle.

Figures 6 and 7 show an open thread cutting ferrule 2, one end of which is provided with a small groove and the other end of which is externally provided with threads. When the open thread cutting sleeve is in tandem movement, the open end is tightened, so that the workpiece is clamped.

Fig. 8 and 9 show the hand wheel sleeve 3 which is connected with the open thread cutting sleeve 2 through threads. By means of the support, the hand wheel sleeve 3 is rotated, and the open thread cutting sleeve 2 is pulled to move, so that the workpiece is clamped.

After the workpiece stretches into the device from the inner hole of the open thread cutting sleeve 2, a strip hole at the tail end of the workpiece is inserted into the positioning pin 4, so that the workpiece is accurately positioned. When the hand wheel 3 rotates rightwards, the open thread cutting sleeve 2 starts to move leftwards under the blocking of the support 1, the open end of the open thread cutting sleeve 2 is driven to move leftwards, the diameter of the open end is reduced, and the workpiece in the open thread cutting sleeve 2 is clamped, so that the workpiece is fixed, and the positioning and fixing of the fixture to the workpiece are realized. After the workpiece is machined, the hand wheel is reversely rotated again, and the open thread cutting sleeve 2 moves rightwards under the action of the tension of the open end, so that the original state is restored. The workpiece is released and can be removed. Thereby completing the whole processing process of the workpiece.
