Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, the three-dimensional adjustment coupling includes connecting bodies at both ends and left and right nut pull rods, and the connecting bodies at both ends are fixedly connected to the cylinder piston rod 4 and the force sensor 2 through threads respectively. Connecting rods 8 and ball joints 9 are respectively arranged in the connecting bodies at both ends to form ball joint rod end joint bearings. The connection of the screw rod 10 on the cylindrical end of the ball joint rod end and the inner thread of the left and right nut pull rods 11 match to form an adjustable connection.

[0014] One end of the ball joint rod end joint bearing, the connecting internal thread matches the external thread of the cylinder piston rod 4, and is directly installed on the cylinder piston rod 4 end; the other end also uses a ball joint ...

Abstract

This invention discloses a three-dimension adjusting coupler whose both ends connector are connected fixedly to thrust transducer through thread and cylinder rod separately, wherein, said connector sets bulb joint inside forming bulb rod end knuckle bearing connected fixedly with each other through left nut pull-rod and right one. The invention can offset deviation in horizontal and vertical direction between both connected centers, and also offset axial clearance simultaneously. It is suitable for longitudinal adjustment test of automobile front seat in various types and specifications.

Description

technical field [0001] The invention relates to a mechanical coupler, in particular to a coupler used in a longitudinal adjustment performance test bench of an automobile front seat. Background technique [0002] The longitudinal adjustment performance test bench of the front seat of the car is composed of cylinder 5, force sensor 2, seat 1 and other components (such as figure 1 shown). [0003] The current method is to fix the force sensor 2 on the seat 1, and then use the connecting rod 3 to connect the cylinder piston rod 4 and the force sensor 2 to transmit pulling force and thrust. Connecting rod 3 two ends are connected with flange. Due to the various types and specifications of the front seat of the car, the center of the force point 7 of the cylinder 5 and the center of the force point 6 of the seat joint are in the horizontal x direction ( image 3 ), the vertical y direction ( figure 2 ), there is a gap in the longitudinal Z direction, which makes the connecti...
