Technical Field

[0001] The utility model relates to the technical field of impact testing machines, in particular to an impact testing machine capable of avoiding wire deviation. Background Art

[0002] The drop weight impact tester is a device used to evaluate the performance and durability of materials and structures under impact loads. It releases a heavy hammer to simulate the impact force that a material or structure may suffer in a real working environment to evaluate its impact resistance and reliability. By measuring the impact load and observing the response of the specimen, the drop weight impact tester provides key data for the development of new materials, the evaluation of product safety and reliability, and the verification of compliance with design and manufacturing standards.

[0003] However, in actual use, the above-mentioned drop hammer impact tester usually connects the impact hammer and the control box through a wire to transmit relevant values ​​obtained by the sensor added to the impact hammer. Since the impact hammer is movable, the wire is not fixed. During the impact test, accidental pulling, tripping or entanglement may occur, thereby interfering with the test process and even causing damage to the equipment. In view of this, we propose an impact tester that can avoid wire deviation. Utility Model Content

[0010] Preferably, the impact hammer is movably connected to the guide rail, so that the impact hammer can move along a predetermined route, thereby improving the accuracy of the impact test.

[0011] Preferably, a control box is fixedly connected to the top end surface of the base, and the control box is fixedly connected to an end of the wire away from the impact hammer.

[0014] Compared with the prior art, the utility model provides an impact testing machine that can avoid wire deviation, and has the following beneficial effects:

[0015] 1. The impact tester capable of avoiding wire deviation is provided with a winding roller, a winding spring, a limit block and a movable block. The winding roller winds up the wire, and when the impact tester is not used, the entanglement of the wire or accidental external pulling is avoided.

The wire is always matched with the length required by the impact tester, and accidental pulling in the impact test is avoided, and interference with the test process is avoided. At the same time, the wire is pulled downward by the movable block without using an impact hammer to pull the wire, thereby reducing the influence of pulling the wire on the test data and improving the accuracy of the test data.

[0016] 2. The impact testing machine can avoid the deviation of the wire. Through the bidirectional screw and belt, when the wire is wound, the bidirectional screw rotates to drive the limit block to make lateral reciprocating motion, so as to achieve uniform arrangement of the wire on the surface of the winding roller, improve the effect of wire winding, and maintain the uniformity of wire tension.

[0023] In one embodiment of the utility model, a winding roller 9 is rotatably connected to the side wall of the mounting plate 8, a wire 7 is wound around the side wall of the winding roller 9, the wire 7 is fixedly connected to the impact hammer 5, a control box 6 is fixedly connected to the top end face of the base 1, the control box 6 is fixedly connected to one end of the wire 7 away from the impact hammer 5, an opening 10 is provided on the side of the winding roller 9 away from the mounting plate 8, a coil spring 11 is fixedly connected to the side wall of the winding roller 9, one end of the coil spring 11 away from the winding roller 9 is fixedly connected to the mounting plate 8, a mounting rod 12 is fixedly connected to the side wall of the mounting plate 8, a limit block 13 is sleeved on the side wall of the mounting rod 12, and a through hole 13 is provided on the top of the limit block 13 The wire 7 passes through the through hole, the limit block 13 guides the wire 7 to avoid the deviation of the wire 7, the side wall of the wire 7 is fixedly connected with a mounting sleeve 14, the side wall of the mounting sleeve 14 is fixedly connected with a connecting rope 15, the end of the connecting rope 15 away from the mounting sleeve 14 is fixedly connected with a movable block 16, the movable block 16 is sleeved with the guide rail 2, the side wall of the mounting plate 8 is rotatably connected with a bidirectional screw rod 17, the bidirectional screw rod 17 is threadedly connected with the limit block 13, the side wall of the limit block 13 is transmission-connected with a belt 18, the belt 18 is transmission-connected with the winding roller 9, and the rotation of the winding roller 9 drives the bidirectional screw rod 17 to rotate through the transmission action of the belt 18.

[0024] The impact hammer 5 hits downward, and the impact hammer 5 releases the limit of the movable block 16. The movable block 16 moves downward, and the wire 7 is pulled downward through the connecting rope 15 and the mounting sleeve 14. The movement of the wire 7 causes the winding roller 9 to rotate, and the rotation of the winding roller 9 causes the coil spring 11 to elastically deform. When the main machine 3 reels the wire rope 4, it drives the impact hammer 5 to rise upward, and the impact hammer 5 drives the movable block 16 to move upward. Since there is no downward pulling force of the movable block 16, the coil spring 11 can drive the winding roller 9 to rotate through elasticity, thereby causing the winding roller 9 to reel in the wire 7. By reeling in the wire 7 When the impact tester is not used, the wire 7 is prevented from being entangled or accidentally pulled by the outside. When the impact tester is used, the wire 7 is limited by the limit block 13 and the movable block 16, so that the wire 7 moves along the guide rail 2. The wire 7 is always adapted to the length required by the impact tester, avoiding accidental pulling during the impact test and interference with the test process. At the same time, the movable block 16 drives the wire 7 to be pulled downward without the impact hammer 5 pulling the wire 7, thereby reducing the influence of pulling the wire 7 on the test data and improving the accuracy of the test data.

[0025] In addition, the side wall of the mounting plate 8 is rotatably connected with a bidirectional screw rod 17, and the bidirectional screw rod 17 is threadedly connected to the limit block 13. The side wall of the limit block 13 is transmission-connected with a belt 18, and the belt 18 is transmission-connected to the winding roller 9. The rotation of the winding roller 9 drives the bidirectional screw rod 17 to rotate through the transmission action of the belt 18. When the wire 7 is wound up, the rotation of the bidirectional screw rod 17 drives the limit block 13 to make a lateral reciprocating motion, thereby realizing a uniform arrangement of the wire 7 on the surface of the winding roller 9, improving the winding effect of the wire 7, and maintaining the uniformity of the tension of the wire 7.

[0026] In the utility model, when in use, the impact hammer 5 is smashed downward, the impact hammer 5 releases the limit of the movable block 16, the movable block 16 moves downward, and the wire 7 is pulled downward by the connecting rope 15 and the mounting sleeve 14. The movement of the wire 7 causes the winding roller 9 to rotate, and the rotation of the winding roller 9 causes the coil spring 11 to elastically deform. When the main machine 3 reels the wire rope 4, it drives the impact hammer 5 to rise upward, and the impact hammer 5 drives the movable block 16 to move upward. Since there is no downward pulling force of the movable block 16, the coil spring 11 is able to elastically drive the winding roller 9 to rotate, and then the winding roller 9 rewinds the wire 7. Further, the rotation of the winding roller 9 drives the bidirectional screw rod 17 to rotate through the transmission action of the belt 18. When the wire 7 is reeled, the rotation of the bidirectional screw rod 17 drives the limit block 13 to make a lateral reciprocating motion, so as to achieve a uniform arrangement of the wire 7 on the surface of the winding roller 9.
