Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the utility model provides a multistation frock for the centre gripping to the hydro-cylinder end cover in the screw hole 12 course of working of hydro-cylinder end cover 1. The center of the oil cylinder end cover 1 is provided with a mounting hole 11.

Multistation frock includes loading board 2 and installs a plurality of anchor clamps on loading board 2, in this embodiment, including first anchor clamps 8 and second anchor clamps 9, the quantity of anchor clamps can change according to actual requirement.

Taking the first clamp 8 as an example, the clamp comprises a mounting base 3, a profiled rod 4, a compression assembly 5 and a nut 6. The mounting seat 3 is fixedly arranged on the bearing plate 2, the mounting seat 3 is an upward protruding convex part, and a square through hole 31 which penetrates through the mounting seat 3 from top to bottom is vertically arranged in the middle of the mounting seat 3. Referring to fig. 1 and 2, the special-shaped rod 4 includes a square column section 41 and a stud section 42, the square column section 41 is disposed in the square through hole 31 and upwardly passes through the mounting hole 11 of the oil cylinder end cover 1, and the stud section 42 downwardly extends out of the bearing plate 2. The pressing assembly 5 is detachably arranged at the top of the square column section 31, extends outwards from the upper part of the mounting hole 11 and presses the oil cylinder end cover 1; the nut 6 is arranged on the stud section 41 on the lower side of the bearing plate 2 and used for adjusting the tightness of the pressing assembly 5. It should be noted that the nut 6 is a butterfly nut, and holding portions 61 are disposed on two sides of the nut.

With reference to fig. 2 and fig. 3, in order to implement the installation of the pressing assembly 5, the pressing assembly 5 includes a first pressing plate 51 and a second pressing plate 52, a first through hole 43 for the first pressing plate 51 to pass through is horizontally disposed on the upper portion of the square column section 41 along a first direction, and a second through hole 44 for the second pressing plate 52 to pass through is horizontally disposed on the upper portion of the square column section 41 along a second direction perpendicular to the first direction; the lower end surfaces of the first pressure plate 51 and the second pressure plate 52 are flush, the height of the first pressure plate 51 is greater than that of the second pressure plate 52, and the middle of the first pressure plate 51 is arranged in a groove 53 for the second pressure plate 52 to pass through. When the device is used specifically, the oil cylinder end cover 1 is placed above the mounting base 3, and then the square column section 4 without the pressing assembly 5 penetrates through the mounting hole 11 from bottom to top until the lower side surfaces of the first through hole 43 and the second through hole 44 are higher than the upper end surface of the oil cylinder end cover 1; and then sequentially passing the first pressing plate 51 and the second pressing plate 52 through the corresponding through holes, and tightening the nut 6 until the pressing assembly 5 is tightly contacted with the oil cylinder end cover 1. It is worth mentioning that the mounting order of the first and second

pressing plates

51 and 52 is irreversible.

In order to facilitate the processing of the threaded hole 12, a plurality of through holes 7 are formed in the position, corresponding to the threaded hole 12, of the periphery of the mounting seat 3 on the bearing plate 2, so that unnecessary damage to a drill bit in the processing process of the threaded hole 12 can be prevented.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
