Description

Technical Field

[0001] This utility model belongs to the field of bucket tooth strength testing technology, and in particular relates to a bucket tooth strength impact testing device. Background Technology

[0002] Impact strength testing machines mainly come in two forms: drop hammer and pendulum hammer, depending on the appearance of the main unit and the object being tested.

[0003] Utility model patent CN212059739U discloses a bucket tooth impact strength testing machine, including a fixed layer, a box, a gravity block, a top layer, and a stabilizing layer. Stabilizing layers are installed on both sides of the bottom of the box, and a fixed layer is installed on the top of the box. Support rods are installed on both sides of the bottom of the top layer and on one side between the stabilizing rods. Lifting blocks are installed on the outer sides of the support rods, and a counterweight box is installed at the bottom of the lifting blocks. Second springs are evenly installed at both ends inside the counterweight box, and a clamping block is installed at the top between the second springs. Rotating rods are installed on both sides of the counterweight box, and a pressing block is installed inside the counterweight box on one side of the rotating rod. A gravity block is installed at the bottom of the counterweight box. This device requires rotating a handle to fix the bucket teeth, and after impact testing, no impact force data is obtained, making it difficult to determine the impact resistance of the bucket teeth. Therefore, a bucket tooth strength testing device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the strength of bucket teeth in an impact test, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1 to 4 The impact testing device for bucket teeth strength shown in this utility model includes an operating table 1, a controller 2 mounted on the operating table 1, a display screen on the controller 2, an impact placement block 3 fixedly connected to the operating table 1, the impact placement block 3 having a groove, a pressure sensor 4 installed in the groove of the impact placement block 3, the pressure sensor 4 being used to detect the value of the impact force on the bucket teeth, two reinforcing frames 5 fixedly connected to the operating table 1, an electric push rod 6 fixedly mounted on the reinforcing frame 5, two fixing rings 7 fixedly connected to the operating table 1, and the electric push rod 6 being a telescopic rod. A connecting rod 8 is connected to the upper part of the bucket, and the connecting rod 8 is slidably connected to the fixing ring 7. A clamping block 9 is fixedly connected to the connecting rod 8, and the clamping block 9 is used to clamp the bucket teeth. A distance sensor 10 is installed on the clamping block 9. Two impact sliding frames 11 are fixedly connected to the operating platform 1. Two hydraulic cylinders 12 are fixedly installed on the operating platform 1. A connecting rod 13 is connected to the telescopic rod of the hydraulic cylinder 12. A sliding plate 14 is slidably connected between the two impact sliding frames 11. The sliding plate 14 is connected to the connecting rod 13. An impact hammer 15 is installed on the sliding plate 14. The impact hammer 15 is used to perform impact tests on the bucket teeth.

[0017] A start button is provided on controller 2.

[0018] Anti-slip pads are attached to clamp 9.

[0019] The working principle of this utility model is as follows: the distance sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0020] After placing the bucket teeth on the impact placement block, press the start button to control the electric push rod. The electric push rod drives the connecting rod, clamping block, and distance sensor to move inward. After the clamping block moves inward to contact the bucket teeth, it clamps and fixes the bucket teeth to prevent them from slipping off the operating table. When the distance between the distance sensor and the fixing ring reaches the first threshold preset by the distance sensor, the electric push rod is controlled to stop working.

[0021] The hydraulic cylinder is controlled to operate, causing the connecting rod, sliding plate, and impact hammer to descend. This allows the impact hammer to impact the bucket teeth. Pressure sensors detect the pressure on the bucket teeth, and the detected data is simultaneously transmitted to the controller display screen and saved for easy review. After the bucket teeth complete the impact test, the hydraulic cylinder is controlled to raise the connecting rod, sliding plate, and impact hammer back to their reset position.

[0022] Press the start button again to control the electric push rod to work in reverse. The electric push rod drives the connecting rod, clamping block and distance sensor to move outward, causing the clamping block to move outward and disengage from the bucket teeth, thereby releasing the fixed state of the bucket teeth. When the distance between the distance sensor and the fixed ring reaches the second threshold preset by the distance sensor, the electric push rod is controlled to stop working.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
