The electric push rod is placed on the test tooling, and then the electric push rod is used to push a heavy object to test the magnitude of the thrust of the electric push rod. However, it is found in the actual test process that since the weight of the heavy object cannot be adjusted, the electric push rod cannot push heavy objects of different weights, resulting in low test accuracy of the electric push rod. For this reason, a test tooling for an electric push rod is proposed. Content of the Utility Model

Both sides inside the fixed frame are fixedly provided with sliding rods. A test push plate is slidably arranged between the two sliding rods. A plurality of evenly distributed additional weight plates are stacked on the upper surface of the test push plate. A hoist is fixedly arranged on the top of the fixed frame. Two pulling ropes are wound around the rotating shaft of the hoist. The ends of the two pulling ropes both extend into the fixed frame and are fixedly provided with hanging pins. Pin slots matched with the hanging pins are opened on both sides of the plurality of additional weight plates.
[0007] Preferably, limiting support rings are fixedly arranged on the rod walls of the two sliding rods, and the test push plate is placed on the tops of the two limiting support rings.

[0013] 1. For this electric push rod test tooling, through the provided weight plates, winch, pulling ropes and hanging pins, when it is necessary to select the number of weight plates to be used, the tester inserts the hanging pins on both sides into the pin slots on both sides of the corresponding number of weight plates respectively, and then by turning on the winch to work, the winch can wind the pulling ropes on both sides and pull the hanging pins upward, so that the excess number of weight plates can be lifted upward, and the weight plates to be used are placed on the upper surface of the test push plate, and thus the thrust of the electric push rod can be adjusted to adjust the test.
[0014] 2.

These are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0022] Refer to Figure 1 and 3 , an electric push rod test tooling, including a fixed frame 1. The bottom of the fixed frame 1 is inserted and placed with an electric push rod 2 to be tested. A positioning cylinder 10 is fixedly provided at the bottom of the fixed frame 1. The bottom of the electric push rod 2 to be tested is placed inside the positioning cylinder 10. A notch is provided on the side wall of the positioning cylinder 10, so that the electric push rod 2 to be tested can be placed stably and vertically. The notch allows the pipeline to pass through; both sides inside the fixed frame 1 are fixedly provided with sliding rods 3. A test push plate 4 is slidably arranged between the two sliding rods 3. Limit support rings 11 are fixedly provided on the rod walls of the two sliding rods 3. The test push plate 4 is placed on the tops of the two limit support rings 11. When the test push plate 4 moves on the sliding rods 3, the downward movement position of the test push plate 4 can be restricted by the limit support rings 11, which can provide a placement space for the electric push rod 2 to be tested; a plurality of evenly distributed weight plates 5 are stacked on the upper surface of the test push plate 4. A winch 6 is fixedly provided at the top of the fixed frame 1. Two pull ropes 7 are wound around the rotating shaft of the winch 6. The ends of the two pull ropes 7 both extend inside the fixed frame 1 and are fixedly provided with hanging pins 8. Pin slots 9 matching with the hanging pins 8 are opened on both sides of the plurality of weight plates 5. When it is necessary to select the number of weight plates 5 to be used, the tester inserts the hanging pins 8 on both sides into the pin slots 9 on both sides of the corresponding number of weight plates 5 respectively, and then by turning on the winch 6 to work, the winch 6 can wind the two pull ropes 7 and pull the hanging pins 8 upward, so that the redundant number of weight plates 5 can be lifted upward, and the weight plates 5 to be used are placed on the upper surface of the test push plate 4. Furthermore, the thrust of the electric push rod can be adjusted to adjust the test. Finally, by controlling the electric push rod 2 to be tested to extend, the electric push rod 2 to be tested can push the test push plate 4 and the weight plates 5 upward and perform the thrust size test.
[0023] Refer to Figure 1-2, on the upper surfaces of multiple additional weight plates 5, two positioning columns 12 are symmetrically fixed. Positioning grooves 13 that cooperate with the positioning columns 12 are formed on the lower surfaces of the multiple additional weight plates 5. Since the multiple additional weight plates 5 are stacked, during the stacking process, the positioning columns 12 are inserted into the interiors of the positioning grooves 13, which can increase the stability of the stacked additional weight plates 5 and avoid the phenomenon of collapse.
[0024] Refer to Figure 1 , on both sides of the top of the fixing frame 1, two positioning tubes 14 are fixedly provided. Two pull ropes 7 respectively pass through the interiors of the two positioning tubes 14; two guide wheels 15 are symmetrically and fixedly provided on the top of the fixing frame 1. The two pull ropes 7 respectively pass through the two guide wheels 15. The positioning tubes 14 and the guide wheels 15 can play a guiding role for the pull ropes 7.
