Embodiment

[0012] Example: Such as image 3 As shown, the operation and use steps of the present invention are as follows, clamp the nut 2 with the block 3, rotate the locking screw 6 on the support body 5, and push the locking block 4 forward, the body 1 is a casting, and the bolt is not necessarily at the center position. The side clearance between the sides of the two locking blocks 4 and the body 1 is different, and the side clearance adjustment can be completed through the support screw 7 on the support body 5, so that the body 1 and the locking device have no side clearance, reaching the lock nut 2 the goal of. The bolt can be easily removed by turning the bolt. After the assembly and disassembly is completed, the locking screw 6 on the support body 5 is reversely rotated to separate the clamping block 3 from the locking block 4, and the locking device withdraws.

Abstract

The invention provides a bolt dismounting and mounting blocking device. Locking blocks and supporting tightened screws are correspondingly installed on the two sides of a supporting body, each supporting tightened screw abuts against one end of the corresponding locking block, the two sides of a clamping block are provided with wedge-shaped grooves, the middle of the clamping block is provided with an opening, and the two sides of the clamping block are in wedged connection with the locking blocks. The middle of the supporting body is provided with a locking screw rod which is in threaded connection with the clamping block. The clamping block and the locking blocks are self-locked in a wedged mode, the locking effect is good, the purposes of fast locking, dismounting and mounting bolts can be achieved, the operation is convenient, the structure is compact, the dismounting and mounting period of a main bearing bolt can be effectively shortened, dismounting and mounting efficiency is improved, the scrap and losses of the main bearing bolt are reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a bolt disassembly and assembly device, in particular to a bolt disassembly and assembly locking device used in a narrow space. Background technique [0002] At present, for the disassembly and assembly of bolts in some narrow spaces, such as the nuts of the known 240 diesel engine main bearing bolts in a narrow space of the diesel engine, it cannot be fixed with a wrench, and the wedge-shaped iron block can only be used to knock the fixed nut with a hammer head. If the wedge-shaped iron block is struck too lightly, or the nut has rounded corners, the nut will slip easily when dismounting the bolt and is not easy to disassemble; It is also not easy to withdraw due to deformation. Often because it cannot be disassembled, it can only be cut off with gas cutting, causing the bolt to be scrapped and cannot be used again. Contents of the invention [0003] In order to overcome the problem that it is difficult to fix bolts in a na...
