The crankshaft connecting rod positioning and pressing structure comprises a crankshaft connecting rod positioning and pressing mechanism, the crankshaft connecting rod positioning and pressing mechanism comprises a crankshaft connecting rod positioning and pressing air cylinder, an air cylinder seat, a guide rail, a sliding seat, an adjusting seat, a positioning seat, a pressing head, a fixed block, a V-shaped block and a connecting rod, the crankshaft connecting rod positioning and pressing air cylinder is fixed to the air cylinder seat, an extension rod of the crankshaft connecting rod positioning and pressing air cylinder is connected with the pressing head, the fixed block is connected with the sliding seat, the sliding seat is slidably connected with the guide rail, the adjusting seat is fixedto the sliding seat, the positioning seat is installed on the adjusting seat, the V-shaped block is connected with the air cylinder seat, one end of the connecting rod is connected with the pressinghead through a pin, and the other end of the connecting rod is connected with the V-shaped block. According to the crankshaft connecting rod positioning and pressing structure, the design is simple and reasonable, safety and reliability are achieved, assembly is convenient, the positioning and pressing effect is good, and using requirements are met.

Description

technical field [0001] The invention relates to a pressing structure, in particular to a positioning and pressing structure of a crankshaft connecting rod in an electric actuator pull rod adjustment structure, which belongs to the field of electric actuators. Background technique [0002] The existing structure has the following defects: the cylinder is pressed directly with the product through the extending rod, resulting in loose pressing, easy loosening, vertical pressing, small space range, difficult installation, and assembly errors. [0003] The publication date is March 27, 2013, and the Chinese patent publication number 102990568A discloses an invention patent named "a connecting rod pressing device". The patent includes a fixture body, jaws, connecting rods, end plates and an adjusting rod as a force application device. The jaws are hinged on the fixture body, and the driven end of the jaws presses the workpiece. The connecting rod is slidably connected to the fixtu...

Problems solved by technology

[0002] The existing structure has the following defects: the cylinder is directly pressed with the product through the extension rod, resulting in loose pressing, easy loosening, vertical pressing, small space range, difficult installation, resulting in assembly errors

Although this patent can fine-tune the jaws by rotating the thread, the pressing is not tight, it is not easy to install, and the assembly error is large, so it still has the above defects
