Description
Technical Field
The utility model belongs to the technical field of agricultural machine, a test bench of harvester gearbox, concretely relates to test piece hold-down mechanism of harvester gearbox multifunctional test platform is related to.
Background
The gearbox test bench is the platform that detects gearbox performance, and current harvester front axle assembly gearbox test bench has following several not enough in the aspect:
1. the device is mostly simple idle running, single in function and fixed in rotating speed, and various performances of the gearbox are difficult to detect.
2. The loading test cannot be carried out, and whether the assembly meets the requirements or not cannot be judged for the meshing transmission kinematic pair.
3. And the data storage function is not available, so that the data analysis and the problem tracing are inconvenient.
Aiming at the defects of the existing gearbox test bed, a test platform capable of realizing multifunctional detection is designed in advance, and multiple test functions such as gear shifting test, loading running-in, differential test, anti-dragging test, stepless torque increasing test, clutch function test, starting torque detection and the like can be realized. Aiming at the predesigned test bed, a supporting mechanism of a test piece, a pressing mechanism of the test piece, a power input mechanism, a loading mechanism and the like need to be protected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the weak point of prior art, provide a simple structure, easy operation convenience's harvester gearbox multifunctional test platform's testpieces hold-down mechanism.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a test piece hold-down mechanism of harvester gearbox multifunctional test platform which characterized in that: comprises a vertical column; a pressing arm support is fixed at the upper end of the upright column, a rotating support shaft penetrates through the upper end of the pressing arm support, a pressing arm capable of rotating around the rotating support shaft is mounted on the rotating support shaft, the rotating support shaft is taken as a decomposition point, the pressing arm is divided into a force application section and an action section, the included angle between the force application section and the action section is A, and A is larger than 90 degrees and smaller than 180 degrees; the end part of the force application section is connected with the cylinder rod end of the pressing cylinder, and the cylinder barrel end of the pressing cylinder is hinged with the upper end part of the upright post; and a pressing action block which is in pressing contact with the test piece is fixed at the lower end part of the action section.
Further: an extension arm is fixed at the upper end of the pressing arm action section, the setting direction of the extension arm is consistent with the setting direction of the pressing arm action section, a pressing rod is vertically installed at the outer end part of the pressing arm, and a pressing head in contact with a test piece is installed at the lower end of the pressing rod.
The utility model has the advantages and positive effect:
1. the pressing mechanism has few components and simple integral structure.
2. This hold-down mechanism stretches out drive pressing arm through the jar pole of cylinder and revolutes and move back shaft clockwise rotation, makes the effect section that compresses tightly the arm rotate to the horizontal position, realizes compressing tightly the testpieces, withdraws drive pressing arm through the jar pole and revolutes and move back shaft counter-clockwise turning, makes the effect section that compresses tightly the arm rotate to the position that inclines upward, relieves the compressing tightly to the testpieces, has convenient operation simple advantage.
