Embodiment approach
[0052] (1) Support arm 100: The material of the support arm 100 that needs to be fixed by bolts in this embodiment is QT450. One end of the support arm 100 is connected to the suspension body 101 by a round hole, and the other end is connected to the engine by three round holes.
[0053] (2) Product bolt 102: bolt material is 40Cr, bolt treated with Dacromet;
[0054] (3) Suspension body 101: The suspension body 101 is used to connect and fix the upper and lower brackets together by riveting.
[0055] (4) Fixture body 1: choose P20 for the plate, and use 40Cr for the rest; the material of fixture body 1 here can also be made of other materials;
[0056] (5) Position-adjustable support arm positioning pin 2-4: the positioning pin uses 40Cr; the positioning pin is embedded on the slider;
[0057] (6) Positioning bolts 2-7: 40Cr inner hexagonal bolts are used as the bolt material, and other materials can also be used instead.

The invention relates to an adjustable suspension bracket fixing bolt tightening clamp which comprises a clamp body, wherein an adjustable positioning mechanism is arranged on the clamp body, the adjustable positioning mechanism comprises a base, a first sliding part and a second sliding part, the first sliding part is arranged at the top of the base and is in sliding connection with the base, thesecond sliding part is arranged at the top of the first sliding part and is in sliding connection with the first sliding part, and the first sliding part and the base are connected through fasteners;the top surface of the second sliding piece is provided with a plurality of position-adjustable bracket positioning pins; and according to the invention, the adjustable bracket positioning pin capable of moving in a plane through the sliding part is arranged to position the bracket, and assembled products can reach the qualified standard through multiple times of debugging, so that the influenceof clamp machining errors and design gaps on product assembly precision is avoided.
Description
technical field [0001] The invention belongs to the technical field of bracket arm assembly of an automobile engine suspension assembly, and in particular relates to an adjustable bracket arm fixing bolt tightening fixture which requires a high degree of position of the bracket arm after the bolt is tightened. Background technique [0002] At present, in the engine mount products, more and more fixing methods are used to connect the support arm and the mount main spring through bolts. Since one end of the engine mount is connected to the body and the other end is connected to the engine, the assembly tolerance requirements are relatively strict. In order to ensure that the position of the suspension support arm meets the design requirements after its fixing bolts are tightened, it is necessary to design a professional assembly fixture to fix the suspension assembly body and support arm, and then tighten the bolts to the design torque. When designing the jig for tightening t...
