Description of the drawings：
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the front view of the overall structure diagram of the utility model.
Fig. 2 is the internal structure schematic diagram of the utility model.
The left view of the utility model during Fig. 3.
Specific embodiment：
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments：
The door lock door knife assembly durability tester of a kind of elevator door-motor as shown in Figure 1 to Figure 3, including rack 1, driving machine
Structure 2, door knife fixed frame 3, door lock fixed frame 4, load counterweight 5, synchronous belt 6, the first slide 7, the second slide 8, the first loading plate 9
With the second loading plate 10,9 level of the first loading plate is fixed in rack 1, and second loading plate 10 is fixed vertically
It is arranged in rack 1, the driving mechanism 2 is fixedly mounted on the second loading plate 10, and first slide 7 is horizontal to be fixedly mounted
In in rack 1,8 level of the second slide is fixedly mounted on the first loading plate 9, and the synchronous belt 6 is connected by drive pulley
Driving mechanism 2 is connected to, 3 lower part of door knife fixed frame is slidably mounted on by sliding block on the first slide 7, the door knife fixed frame
3 tops are fixedly mounted on synchronous belt 6, and load 5 lower part of counterweight is slidably mounted on by sliding block on the second slide 8, described
Door lock fixed frame 4 is fixedly mounted on load counterweight 5 top by waist-shaped hole, with realize lock on the door position that fixed frame 4 installs into
Row fine tuning, tested door knife 13 and tested door lock 14 are respectively and fixedly installed to a knife fixed frame 3, on door lock fixed frame 4, driving mechanism
2 driving synchronous belts 6 drive door knife 13 to realize left and right reciprocating motion, are realized while door knife 13 moves back and forth and door lock 14 is carried out
Simulation opening and closing test.
The driving mechanism 2 includes driving motor and transformer, and the Transformer Selection rotation in the driving mechanism 2
Transformer, the operation principle and common transformer of rotary transformer are substantially similar, primary side, secondary difference lies in common transformer
Winding is relatively-stationary, so output voltage and input voltage ratio are constants, and the primary side of rotary transformer, vice-side winding
The change of relative position then occurs with the angular displacement of rotor, thus the size of its output voltage becomes with rotor angular displacement
Change, export the voltage magnitude of winding and angle of rotor into sinusoidal, cosine function relationship or keep a certain proportionate relationship or one
It is interior linear with corner to determine angle range, since the test process for knife assembly of locking a door on the door is constantly reciprocal analog survey
Examination mode, therefore longer service life is respectively provided with firstly the need of all parts for ensureing test machine, and rotary transformer is then full
The requirement of service life length when foot is back and forth tested, therefore can ensure the accuracy of test result and improve the whole of test machine
Body service life.
In actual use, due to the heavier mass of load counterweight 5, in order to avoid load counterweight 5 is because of its inertia mistake
Greatly rack 1 is caused to hit, two limiting buffer blocks 12 are further fixedly arranged in the rack 1, two limiting buffer blocks 12 are right
Claim to be arranged on the arranged on left and right sides of the second slide 8, so, rack 1 can be avoided to damage when being hit, Jin Erti
The high service life of test machine rack 1.
In addition, in order to which test area and non-test region is completely isolated, so as to fulfill certain security, the rack
Protective door is additionally provided with outside 1, meanwhile, 1 horizontal level of rack is finely adjusted to adapt to different working environments in order to realize,
1 bottom of rack is provided with height regulation pin 11.
It is emphasized that：The above is only the preferred embodiment of the present utility model, and not the utility model is appointed
What formal limitation, every any simple modification made according to the technical essence of the utility model to above example, etc.
With variation and modification, in the range of still falling within technical solutions of the utility model.
