Problems solved by technology
The patent document with the publication number CN102435944A discloses a test system using a rotary servo motor and a ball screw as a loading device, but since the motion drive part uses a ball screw, the rotary motion of the drive motor is converted into a linear motion. Due to the mechanical structure of the ball screw used in this method, there are deficiencies such as large friction, reverse transmission clearance, step-by-step power transmission, and large position inertia, which will seriously reduce the detection accuracy of the test device.

Embodiment Construction
[0020] see figure 1 As shown, according to an embodiment of the present invention, a linear motor performance testing device is provided, including a fluid-driven telescopic component 1 and a tension pressure detection component 2. The fluid-driven telescopic component 1 is connected to the mover 32 of the linear motor to Drive the mover 32 to generate a linear motion relative to the stator 31 of the linear motor, and the pull pressure detection part 2 is used to detect the pull pressure between the fluid-driven telescopic part 1 and the mover 32 during movement The change. In this technical solution, the combined transmission mode of the rotary motor and the ball screw in the prior art is replaced by the fluid-driven telescopic part 1, so that the structure of the test device is particularly simple and reasonable. The movement can be directly transmitted to the mover 32, avoiding the hysteresis of the transmission response caused by the inertia of the ball screw in the prior...

Description
technical field [0001] The invention belongs to the technical field of motor performance testing, and in particular relates to a linear motor performance testing device. Background technique [0002] The linear motor can be used to directly drive the load to achieve linear motion. Compared with the common "rotary motor + ball screw" driving method, this method does not require an intermediate transmission link, so that the servo system formed has fast response speed and high precision. Based on the advantages of high speed, high acceleration, high speed, high rigidity, and low operating noise, linear motors are widely used in high-precision fields such as CNC machine tool machining centers and robots. Compared with foreign countries, my country's linear motor research started late, the level is low, and there is a lack of mature products. In order to improve the level of design and use, it is very necessary to carry out necessary performance testing on the linear motor to e...
