Gearbox gear shift mechanism force measuring device

Abstract

A gearbox gear shift mechanism force measuring device comprises a fixed base frame and a moving base frame which are arranged on a table board. A lower bracket is arranged on the outer side of the fixed base frame. A horizontal transverse shift mechanism is arranged on the lower bracket. The horizontal transverse shift mechanism comprises a left-right transverse shift screw rod supported by the lower bracket and a transverse shift slider connected in a threaded manner to the transverse shift screw rod. A vertical frame is arranged on the transverse shift slider. A vertical lifting mechanism isarranged on the vertical frame. The vertical lifting mechanism comprises a lifting screw rod supported by the vertical frame and a lifting slider connected in a threaded manner to the lifting screw rod. A support seat is arranged on the lifting slider. A horizontal longitudinal shift mechanism is arranged on the support seat. The horizontal longitudinal shift mechanism comprises a front-back longitudinal shift screw rod supported by the support seat and a longitudinal shift slider connected in a threaded manner to the longitudinal shift screw rod. A digital display tension meter is fixed on the longitudinal shift slider. The test rod of the digital display tension meter is connected with a force measuring connector. The gearbox gear shift mechanism force measuring device can adapt to theforce measurement of gearbox gear shift mechanisms with different specifications. The force measuring process is stable. The measured data is accurate. The device is convenient and labor-saving.

Description

technical field [0001] The invention relates to a force measuring device for a gear box shifting mechanism. Background technique [0002] As a device for transmitting power, the gearbox needs to transmit different speed ratios, so the gearbox shifting mechanism emerges as the times require. In the gearbox cylinder shifting mechanism, the air source is used as the power source, and the cylinder is used as the actuator to push the shifting mechanism to achieve shifting. When the gearbox is assembled, the shifting mechanism is adjusted according to the conditions so that the shifting force meets the design requirements. Therefore, after the gearbox is assembled, the shifting force of the gearbox needs to be checked statically. At present, the force measurement method of gear box shifting mechanism is to pull the piston rod of the cylinder by manually operating the spring tension gauge, and read the measured value from the tension gauge. This method of operation has the follow...

Problems solved by technology

This method of operation has the following disadvantages: when pulling the force, the pulling angle will be different depending on the person, which directly affects the accuracy of the measurement results; when the pulling force is different from person to person, the pulling speed is different, making the measurement results fluctuate greatly
