Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-4, the present embodiment provides a leveling mechanism, which includes a base 1 and a sliding member 2. The base 1 comprises a bottom plate 11 and a connecting piece 12, and the connecting piece 12 is detachably connected with the bottom plate 11. In a specific embodiment, the connecting member 12 includes two side plates 121, and the two side plates 121 are respectively disposed on two opposite side walls of the bottom plate 11. Two opposite side walls of the two side plates 121 and the bottom plate 11 are connected by screws. A nut 122 is arranged between the two side plates 121, and the bolt is in threaded connection with a threaded hole in the nut 122. Meanwhile, the head end of the bottom plate 11 is provided with a connecting part used for being connected with a reference piece, and the head end of the sliding piece 2 is provided with a fitting part fitted with a piece to be leveled. The connecting piece 12 is provided with a threaded hole, and the threaded hole is in threaded connection with a bolt for pushing the sliding piece 2 to drive the piece to be leveled to align with the reference piece. The tail end of the sliding piece 2 is connected with the thread head of the bolt, and the feeding direction of the bolt is the same as the length direction of the base 1.

In the existing leveling device, a to-be-leveled piece is directly pressed by a bolt, and the bolt is continuously attached to and rotates on the outer wall of the to-be-leveled piece in the leveling process, so that the outer wall of the to-be-leveled piece can be damaged. And the area of the thread head of the bolt is too small, the stress area is small, the stress on the outer wall of the part to be leveled is unbalanced, and the conditions of local rising or rising of one side and descending of the other side under stress are easy to occur. In the scheme, the bolt pushes the sliding part 2 to drive the part to be leveled to align with the reference part. The bolt drives the part to be leveled to align with the reference part through the sliding part 2, and does not directly apply force to the outer wall of the part to be leveled, so that the outer wall of the part to be leveled cannot be damaged. And the stress area is increased through the sliding part 2, so that the stress of the outer wall of the part to be leveled is balanced, and the conditions of local rising or rising of one side and falling of the other side under stress can not occur. Meanwhile, the connecting piece 12 is detachably connected with the bottom plate 11, so that the connecting piece 12 can be disassembled and recycled by rotating the screw after the leveling operation or under the condition that the base 1 is damaged, the connecting piece 12 can be continuously used when the leveling operation is performed next time, the utilization rate of objects is improved, and consumables are saved.

In a further aspect, both side plates 121 include a slide plate 1211 and a fixing plate 1212. The inner surface of the sliding plate 1211 is attached to the outer surface of the fixing plate 1212, the outer surface of the fixing plate 1212 is provided with a sliding groove 1213, and the sliding block is slidably arranged in the sliding groove 1213. And the slide block is provided with a threaded hole, the slide plate 1211 is provided with a limiting hole, and a screw rod capable of being inserted into the threaded hole is inserted into the limiting hole. The head end of the sliding plate 1211 is connected to the nut 122, and the fixing plate 1212 is screwed to the base plate 11. Different plate members have different thicknesses of connecting angles or supporting members, and when the thicknesses of the connecting angles or the supporting members are different, the spacing distance between the bolt and the bottom plate 11 is different. If the spacing distance between the bolt and the bottom plate 11 is consistent all the time, when a plate with too thick connecting angle steel or a supporting piece is encountered, the situation that the bottom plate 11 and the bolt are both located on the same plate can occur. The distance between the bolt and the bottom plate 11 is adjusted by sliding the sliding plate 1211 and the fixing plate 1212, so that the adjusting mechanism is suitable for various types of plate members.

Meanwhile, in order to prevent the slider 2 from shifting left and right in the sliding process, the outer walls of the two side plates 121 are provided with limit plates 123, the inner side walls of the limit plates 123 are provided with feed grooves 124, the two opposite side walls of the slider 2 are provided with feed blocks, and the feed blocks are slidably arranged in the feed grooves 124. The limiting plate 123 limits the left and right directions of the slider 2, and prevents the slider 2 from shifting left and right during sliding.

Specifically, in the present embodiment, the sliding member 2 includes a pushing block 21 and a sliding block 22. The opposite two side walls of the sliding block 22 are provided with the feeding blocks, and the head end surface of the sliding block 22 is provided with the fitting part. The tail end face of the sliding block 22 is connected with the head end face of the pushing block 21, and the tail end face of the pushing block 21 is abutted to the thread head of the bolt. The thickness of the pushing block 21 is larger than the diameter of the bolt, and the thickness of the sliding block 22 is smaller than that of the pushing block. The thickness of the pushing block 21 is larger than the diameter of the bolt, so that the pushing block 21 can receive the knob force of the bolt 3, and the thickness of the sliding block 22 is smaller than that of the pushing block, so that the whole volume of the sliding piece is reduced, and the use of materials is saved.

As a preferred embodiment, the connection mode of the connection portion in this embodiment is spot welding. The connection mode of the connecting part is spot welding, so that the bottom plate 11 is tightly connected with the reference piece, and if the bottom plate 11 and the reference piece are only in common attachment, the tight connection between the bottom plate 11 and the reference piece is difficult to ensure without a gap, and certain influence is caused on the leveling precision. And the connection mode through connecting portion is spot welding for after leveling, can directly break off bottom plate 11 and reference piece, be convenient for separate. Of course, other connection methods known in the art can be used while ensuring that the base plate 11 and the reference member are connected stably and easily.

In addition, still include the plum blossom handle in this scheme, the head of tying of bolt is fixed to be set up in the bottom face of plum blossom handle. Through setting up the plum blossom handle, the knob of the bolt of being convenient for has improved work efficiency.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
