Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

In describing the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation , are constructed and operated in a specific orientation and therefore cannot be construed as limiting the invention.

Example:

Referring to Fig. 1-Fig. 4, a special tooling for steam turbine valve body processing, including a workbench 1 for placing valve body installation parts, a semi-circular protective cover 8 is installed on the plane of the workbench 1, and The material of the protective cover 8 is acrylic plate or aluminum alloy, which can effectively intercept waste chips on the workbench 1 and prevent the waste chips from spreading around the air. Two sets of guide columns 2 are welded and installed on the workbench 1. 2 is equipped with a movable rod 6 that can be lifted, and a limit disk 601 is also arranged in the guide column 2. The limit disk 601 is installed on the bottom of the movable rod 6 to prevent the lifting from being too high and cause the movable rod 6 to derail. The sidewall of 2 is also equipped with the fixing bolt 7 that can fix the movable rod 6, when the height of the movable rod 6 needs to be adjusted, the fixing bolt 7 is unscrewed earlier, and then when the height of the movable rod 6 is manually adjusted, directly Tightening the fixing bolt 7 can adapt to the operating heights of different workers and improve the convenience of subsequent processing.

In addition, a rotating rod 5 that can slide or rotate is installed on the guide post 2, a four-corner twisting rod is installed at one end of the rotating rod 5, and a support rod 4 is welded and installed at the other end of the rotating rod 5, and the four corners are screwed by a manual knob. Rotate the support rod 4 or push and pull it in translation. After moving or rotating to a suitable position, use the first locking bolt 501 installed on the top of the movable rod 6 to lock, and turn the first locking bolt 501 to the bottom to make the Its contact end is offset against the rotating rod 5, thereby ensuring the stability of the rotating rod 5 and improving the precision and practicability of the device.

What needs to be explained is that the clamp 3 with a "U"-shaped structure welded on the support rod 4 has a relatively stable structure and is suitable for clamping different levers so that it can be fixed smoothly. The "U" of the clamp 3 The shaped ends are equipped with an upper block 301 and a lower block 302 respectively, and the contact ends of the upper block 301 and the lower block 302 are anti-slip mats made of circular anti-slip rubber or silica gel pads, which have strong adsorption capacity. It can play an anti-slip effect, because the lever surface can be closely attached to the anti-slip mat while the surface of the lever is in contact. The circular anti-slip mat can automatically fit and adjust according to the different degrees of unevenness of the lever surface, and then rotate the torsion bar 304 to drive the second The locking bolt 303 tightens the lower block 302. At the same time, a side block 305 is also installed on the side wall of the fixture 3. When the lower block 302 is against the bottom of the lever, the second block can be driven by rotating the torsion bar 304. The locking bolt 303 tightens the side block 305, so that the contact surface of the side block 305 can be against the side end of the lever, and the force direction of the side block 305 and the lower block 302 are vertically corresponding, on the one hand, the lever can be stabilized. Both ends make it stable during the grinding process and improve the accuracy of grinding. On the other hand, it can also rotate the lever during the process of turning the lever to ensure that the two sets of fixtures 3 can rotate stably on the same level to improve the grinding efficiency. To reduce the labor intensity of workers, when it is necessary to turn over, manually tighten the two sets of first locking bolts 501, and then turn the four-corner screw rod to drive the rotating rod 5 to rotate. During the rotation process, 360° rotation without dead angle can be realized , to ensure better cleaning efficiency during the grinding process, and finally tighten the two sets of first locking bolts 501, so as to achieve the effect of turning over cleaning and grinding, and improve the practical convenience of the device.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
