[0029] The surface of detection cabinet body 1 is embedded with control panel 4

[0030] The upper surface of storage cabinet 2 is installed with steel beam 9, and the upper surface of steel beam 9 is installed with gap measuring mechanism 5 at one end, gap measuring mechanism 5 is installed with tension and compression force sensor buffer mechanism 6 at one side, and tension and compression force sensor buffer mechanism 6 is connected with assembly clamping mechanism 8 through force link 7 at one end;

[0031] The weight mechanism 3 is composed of main weight combination 301, main weight pull rod 302, main weight stand 303, auxiliary weight combination 304, auxiliary weight pull rod 305 and auxiliary weight stand 306, the main weight combination 301 and auxiliary weight combination 304 are symmetrically arranged, the main weight pull rod 302 is movably inserted into the main weight stand 303, the main weight pull rod 302 is connected to the main weight pull rod 302 at the top, the auxiliary weight combination 304 is movably inserted into the auxiliary weight stand 306, and the auxiliary weight combination 304 is connected to the auxiliary weight pull rod 305 at the top.

[0032] In the embodiment, as Figure 1 shown, the control panel 4 is provided with ammeter, voltmeter, tension and compression force meter, stroke speed meter, detection cable connection socket, each control switch, indicator light, output jack and safety tube.

[0033] It should be noted that the control panel 4 is mainly used for loading of test bench power supply, monitoring of each data, electrical connection of each type of electric mechanism, action control and state display of electric mechanism.

[0034] In the embodiment, as Figure 3As shown, the gap measuring mechanism 5 is composed of a gap measuring front sleeve 501, a gap measuring rear sleeve 502, a gap measuring sliding sleeve 503 and a gap measuring hand wheel 504. The gap measuring front sleeve 501 and the gap measuring rear sleeve 502 are respectively located at both ends of the gap measuring mechanism 5. The gap measuring sliding sleeve 503 is located in the inner cavity of the gap measuring mechanism 5. The gap measuring hand wheel 504 is rotatably arranged on the surface of the gap measuring mechanism 5.

[0035] It should be noted that when measuring the gap, first tighten the positive and negative threaded locking rod, lock the female to tightly hold the transmission rod 7. When rotating the gap measuring hand wheel 504 clockwise, the transmission rod 7 moves to the left. When rotating the gap measuring hand wheel 504 counterclockwise, the transmission rod 7 moves to the right. This mechanism is used when measuring the gap of the electric mechanism.

[0036] In this embodiment, as shown in the figure, Figure 4 The tension and pressure sensor buffer mechanism 6 is composed of a tension and pressure sensor pull rod 601, a tension and pressure sensor 602, a tension and pressure sensor connecting plate 603 and a limiting plug 604.

When the tension exceeds 1431N, the limiting column jumps out of the T-shaped groove upward to overcome the spring pressure, and the tension and pressure sensor pull rod 601 moves to the left. With the increase of tension, the limiting column continuously rises under the action of the inclined surface of the T-shaped groove, and the tension and pressure sensor pull rod 601 continuously moves to the left.

The connecting lug 803 and the assembly plate positioning hole 802 are movably inserted with the assembly plate positioning pin.

[0039] It should be noted that the assembly clamping mechanism 8 is installed on the steel beam 9 at the left end of the detection cabinet body 1, and the assembly clamping mechanism can clamp 8 kinds of connecting lugs 803 according to the current design of the electric mechanism product, and each lug corresponds to a product. The assembly clamping turntable 801 can rotate, and the lug position is fixed by the positioning pin. High precision is required during processing to ensure dimensional accuracy and geometric tolerance, and to prevent displacement of the electric mechanism during detection.

[0040] The working principle and use process of the utility model are as follows: the steel beam 9 is installed on the table top of the detection cabinet body 1, the steel beam 9 has the assembly clamping mechanism 8 at the left end, the gap measuring mechanism 5 at the middle part, the tension and compression force sensor buffer mechanism 6, the transmission rod 7 penetrates through the gap measuring mechanism 5 and is connected with the tension pulley through the steel cable joint, the loading force amplification pulley B transmits the load to the tension pulley through the tension shaft, the weight force is loaded on the electric mechanism through the transmission rod connecting lug. The counter force is assembled at the right end of the transmission rod 7, and the counter force fixes the transmission rod and the transmission rod 7 together. The steel cable joint at the left end of the transmission rod is connected with the tension pulley, the loading force amplification pulley A transmits the load to the tension pulley through the tension shaft, and the electric mechanism receives the load of the main weight combination 301 at the left end of the cabinet during the tension test. The electric mechanism receives the load of the auxiliary weight combination 304 at the right end of the cabinet during the tension test. Due to the design of the combined weight and the cabinet type loading test mode, the path of the load transmission mode is increased, which brings complex friction. In order to accurately load the force, the counterweight and the auxiliary weight combination 304 are increased, which are installed at the other end of the loading force amplification pulley and form a lever principle with the main weight combination 301. The mass of the auxiliary weight combination 304 is the sum of all friction forces.
