Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

As shown in fig. 1 to 5, a valve body fixing device of convertible position appearance, includes workstation 1, it has rotor plate 2 to articulate on the workstation 1, rotor plate 2 is fitted with a contraceptive ring and is equipped with four clamping jaws 3, clamping jaw 3 encloses into annular radial and rotor plate 2 along self and slides continuously, the terminal surface of keeping away from clamping jaw 3 on the rotor plate 2 is equipped with drive disc 4, be equipped with on the drive disc 4 with clamping jaw 3 sliding fit and promote the spout 4a that clamping jaw 3 removed, drive disc 4 is connected with driving motor 5.

The improved rotary table is characterized in that a reserved square hole 1a is formed in the working table 1 to ensure that the rotary plate 2 is smooth in the overturning process and avoid movement interference, a positioning block 6 which is supported on the working table 1 after the rotary plate 2 rotates anticlockwise by 90 degrees is arranged at the top of the rotary plate 2, a positioning long plate 7 which is horizontally supported on the working table 1 is connected to the bottom of the rotary plate, a groove 7a is formed in the right end face of the positioning long plate 7, and the groove 7a is matched with a fixing block 8 and the fixing block 8 is connected with a pushing cylinder 9.

The clamping jaws 3 are matched with slideways 2a arranged on the rotating plate 2.

The clamping jaw 3 comprises a clamping hook 31, an upright post 32 connected to the clamping hook 31 and matched with the slide way 2a, and a cylinder 33 connected to the upright post 32 and matched with the slide groove 4 a. In this way, the middle part of the clamping jaw 3 cooperates with the rotating plate 2 through the upright 32, avoiding the rotation of the clamping jaw 3 and guaranteeing the clamping of the valve body 11.

The four sliding grooves 4a are formed in the driving disc 4, and the four sliding grooves 4a are respectively in one-to-one correspondence with the four clamping jaws 3.

The sliding groove 4a is arc-shaped and gradually reduces the curvature radius close to the center of the driving disk 4. In this way, in the process of driving the disc 4 to rotate, the sliding grooves 4a directly push the clamping jaws 3 to move close to each other, so that the valve body 11 is clamped quickly.

A rotating motor 10 is connected to the rotating shaft of the rotating plate 2.

When the rotary table is used, the end face of the valve body 11 is placed between the clamping jaws 3, the driving motor 5 drives the driving disc 4 to rotate, the sliding groove 4a pushes the clamping jaws 3 to slide along the sliding ways 2a due to the fact that the curvature radius of the sliding groove 4a is gradually reduced, the valve body 11 is clamped and fixed, the rotary plate 2 is supported on the working table 1 through the long positioning plate 7, stability is kept, the air cylinder 9 is pushed to push the fixing block 8 to be clamped with the groove 7a, the rotary plate 2 is further completely fixed on the working table 1, and the valve body 11 is machined through external polishing equipment or a horizontal milling machine.

When the valve body 11 needs to be changed in machining position, the rotating motor 10 drives the rotating plate 2 to turn 90 degrees anticlockwise, so that the rotating plate is supported on the workbench 1 through the positioning block 6, and the machining and manufacturing of the upper end face of the valve body 11 can be facilitated when equipment such as an external drilling machine is used for the purpose.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
