WQ-JXTL multiple cam mechanism dynamic test bench bench for a typical cam and groove wheel mechanism design and comprehensive experiment, is one of the important equipment to build the mechanical laboratories. Pilot project: a plate line cam mechanism: ◎ through multimedia software for motion parameters to optimize the design of the cam mechanism. ◎ perform test and simulation eight kinds of disc cam mechanism putter line movement rule. 2 cylindrical cam mechanism:. ◎ be measured and simulation of two cylindrical cam actuator rod movement rule. The main configuration and technical parameters: ◎ plate line cam 4 (8 kinds of sports law); ◎ putter lift h = 15; ◎ grating angular displacement sensor 5V/1000P / turn 2; ◎ linear displacement sensor a range 0 - 16mm Linearity error <0.5%; ◎ cylindrical cam 1 (two kinds of sports law); ◎ speed range: 0 ~ 200r/min; ◎ DC motor with a reducer power 90W; ◎ weight 50kg; ◎ Dimensions 680 × 480 × 720.
