Embodiment 1

[0046] combine Figure 1-8As shown, the signal converter test tool provided by the present invention includes a loading module 100, a measuring module 200 and a dematerializing module 300. The loading module 100 includes a workbench 110, a first fixed connection to the workbench 110. The electric push rod 120, the first electric push rod 120 provides power for the feeding and testing of the signal converter, and the transverse plate 130 fixedly connected with the first electric push rod 120, the transverse plate 130 drives the insertion rod 260 to move downward, During the process of inserting the rod 260 into the slot 250, the rectangular block 240 on which the power connector 270 is installed is urged to connect with the signal converter, so as to complete the measurement operation, be fixed to the side of the horizontal plate 130 and be perpendicular to the horizontal plate 130 The L-shaped rod 140 is symmetrical in the center plane. The L-shaped rod 140 exerts a downward f...

Embodiment 2

[0057] combine Figure 1-5 and Figure 8 As shown, on the basis of the first embodiment, the signal converter test tool also includes six guide posts, and the six guide posts are fixedly mounted inside the two openings in groups of three, and the frame body 310 is movably sleeved. Connected to the outside of the plurality of guide posts, the guide posts are used to limit the position of the frame body 310 to prevent the frame body 310 from moving freely in the measurement cavity, so that the material removal operation can be carried out more smoothly.

Embodiment 3

[0059] combine Figure 1-6 As shown, in the above-mentioned embodiment, two guide plates 400 are fixedly connected to the top of the worktable 110, the guide plates 400 are respectively located outside the two feeding frames 150, and the guide plates 400 are arranged in a trapezoid shape. The measuring cavity is located between the chute and the accommodating cavity, and the guide plate 400 is used to limit the signal converter sliding down on the worktable 110 to prevent the signal converter from sliding to other positions on the worktable 110, so that the signal converter can It slides into the measuring chamber by itself.

[0060] The working principle and use process of the present invention: in the initial state, the signal converter is filled in the barrel 160, and then the front side of the feeding frame 150 connected to the barrel 160 is lifted upwards. When the utility model is put into practical use, the first An electric push rod 120 drives the horizontal plate 130...

Abstract

The invention discloses a signal converter test tool, which includes a loading module, a measuring module and a stripping module. The loading module includes a worktable, a first electric push rod fixedly connected to the workbench, and the first The horizontal plate fixed to the electric push rod, the L-shaped rod fixed to the side of the horizontal plate and symmetrical with respect to the vertical center plane of the horizontal plate, and the material delivery frame installed between the two L-shaped rods. In the present invention, the first electric push rod drives the horizontal plate connected with the L-shaped rod to descend, and the L-shaped rod prompts the front side of the material delivery frame to tilt down, and the material cylinder connected with the material transmission frame moves accordingly, and the signal in the material cylinder is converted The device slides along the feeding frame into the measuring cavity. In addition, the horizontal plate pushes the insertion rod to coincide with the slot, and the rectangular block moves to the rightmost side of the chute. The power connector connected with the rectangular block passes through the circular through hole and the signal conversion Connected with the device, the measurement operation is completed, and the loading operation is automatically completed under the mechanical transmission. The high degree of automation makes the measurement effect high and the measurement cost low.

Description

technical field [0001] The invention relates to the technical field of signal converter testing, in particular to a signal converter testing tool. Background technique [0002] A signal converter is a device that converts electrical signals into digital signals through the principle of digital electricity, which requires professional chip processing. The IK standard signal converter is used in conjunction with various instruments in the industrial automation control system to realize the conversion of standard signals into switch values ​​and replace the output of PLC under certain conditions. [0003] The measurement tooling used for the signal converter needs manual intervention to complete the loading, positioning, measurement and unloading operations of the converter during the measurement operation. With manual intervention, the test efficiency is low, the measurement cost is high, and the labor of other personnel Great strength. SUMMARY OF THE INVENTION [0004] Th...
