Description

Technical Field

[0001] The utility model relates to the technical field of impact testing machines, in particular to an impact testing machine. Background Technique

[0002] An impact testing machine refers to a material testing machine that applies an impact test force to a specimen to conduct an impact test. Impact testing machines are divided into manual pendulum impact testing machines, semi-automatic impact testing machines, digital display impact testing machines, microcomputer-controlled impact testing machines, drop hammer impact testing machines, and non-metal impact testing machines, etc. By replacing the pendulum and the specimen base, tests in two forms of simply supported beam and cantilever beam can be realized.

[0003] When producing plastics, a cantilever beam impact testing machine is often used to test the impact resistance of plastics. When using a cantilever beam impact testing machine, it is necessary to first use a fixture to clamp the material, and then use a pendulum to impact the material. The existing impact testing machines do not have the function of self-cleaning. Since some materials cannot withstand the impact during testing and will be crushed, the debris will fall into the fixture and need to be cleaned manually, which is rather troublesome. Therefore, in view of the above situation, there is an urgent need to develop an impact testing machine that is convenient for cleaning and collecting the debris generated during impact testing and saves manpower, so as to overcome the deficiencies in current practical applications and meet the current needs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an impact testing machine to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An impact testing machine includes a chassis, a protective door, an electromagnet, a transfer board, a pendulum, a support box, a clamping block, a flipping mechanism, a vibration chip removal mechanism, and a garbage box.

Two protective doors 2 are installed on the front side of the chassis 1. The protective door 2 is rotatably connected to the chassis 1 through a hinge. The protective door 2 is made of a transparent material. A transfer board 5 is fixed on the top of the chassis 1. An electromagnet 4 is fixed on the transfer board 5. The electromagnet 4 forms a 60° angle with the horizontal plane. A pendulum 6 is rotatably connected inside the chassis 1. A support box 7 is arranged inside the chassis 1 below the pendulum 6. A clamping block 8 is fixed inside the support box 7. A clamping groove 801 is arranged on the clamping block 8. A clamping bolt 802 screwed into the clamping groove 801 is installed on the clamping block 8. A flipping mechanism 9 for driving the support box 7 and the clamping block 8 to flip up and down is installed inside the chassis 1. A vibration chip removal mechanism 10 is installed at the bottom of the support box 7. A trash box 11 is placed inside the chassis 1 below the support box 7. During use, first raise the pendulum 6 so that the electromagnet 4 attracts the pendulum 6. Then, place the plastic to be tested into the clamping groove 801 (the top of the plastic extends outside the clamping groove 801), and then tighten the clamping bolt 802 to clamp the plastic. Then, close the two protective doors 2, and then turn off the electromagnet 4. The pendulum 6 impacts the plastic fixed on the clamping block 8 under the action of gravity. During cleaning, raise the pendulum 6 to the position of the electromagnet 4 and attract it. Then, drive the support box 7 and the clamping block 8 to flip up and down through the flipping mechanism 9 so that the clamping block 8 faces the trash box 11. Finally, vibrate the support box 7 and the clamping block 8 through the vibration chip removal mechanism 10. Under the action of vibration, the residual debris in the clamping block 8 falls into the trash box 11 and is collected.

[0024] The flipping mechanism 9 includes: a first motor 901, a first gear 902, a second gear 903 and a transmission shaft 904. The first motor 901 is fixed inside the chassis 1. A first gear 902 is installed on the output shaft of the first motor 901. A second gear 903 meshing with the first gear 902 is installed on one side of the first gear 902. The second gear 903 is installed on the transmission shaft 904. The transmission shaft 904 is fixed to the bottom of the support box 7. The transmission shaft 904 is rotatably connected inside the chassis 1. During use, drive the first gear 902, the second gear 903 and the transmission shaft 904 to rotate through the first motor 901, and drive the support box 7 to rotate through the rotation of the transmission shaft 904.

[0025] The vibration chip removal mechanism 10 includes: a rotating shaft 1001, a synchronous pulley 1002, a synchronous belt 1003, a cam 1004, and a second motor 1005. Two rotating shafts 1001 are rotatably connected to the bottom of the support box 7. A synchronous pulley 1002 is installed on each rotating shaft 1001. The two synchronous pulleys 1002 are drivingly connected by a synchronous belt 1003. A cam 1004 is installed on each rotating shaft 1001. The second motor 1005 is fixed to the bottom of the support box 7. The output shaft of the second motor 1005 is connected to one of the rotating shafts 1001. During use, the second motor 1005 drives the rotating shaft 1001 to rotate. The rotation of the rotating shaft 1001 drives the cam 1004 to rotate. The rotation of the cam 1004 vibrates the support box 7.

[0026] A control panel 3 is installed on the side of the chassis 1. The electromagnet 4, the first motor 901, and the second motor 1005 are all electrically connected to the control panel 3 for convenient control.

[0027] Working principle: When this impact testing machine is in use, first raise the pendulum 6 so that the electromagnet 4 attracts the pendulum 6. Then, place the plastic to be tested into the card slot 801 (the top of the plastic extends outside the card slot 801), and then tighten the clamping bolt 802 to clamp the plastic. Then, close the two protective doors 2, and then turn off the electromagnet 4. The pendulum 6 impacts the plastic fixed on the clamping block 8 under the action of gravity. During cleaning, raise the pendulum 6 to the electromagnet 4 again to be attracted. Then, the first motor 901 drives the first gear 902, the second gear 903, and the transmission shaft 904 to rotate. The rotation of the transmission shaft 904 drives the support box 7 and the clamping block 8 to turn up and down, so that the clamping block 8 faces the trash box 11. Finally, the second motor 1005 drives the rotating shaft 1001 to rotate. The rotation of the rotating shaft 1001 drives the cam 1004 to rotate. The rotation of the cam 1004 vibrates the support box 7 and the clamping block 8. Under the action of vibration, the residual debris in the clamping block 8 falls into the trash box 11 and is collected.
