Description

Technical Field

[0001] The utility model relates to the field of spring testing, in particular to an automatic spring testing machine. Background Art

[0002] Springs are a type of elastic element widely used in the mechanical and electronic industries. When loaded, springs can produce large elastic deformations, converting mechanical work or kinetic energy into deformation energy. After unloading, the springs’ deformation disappears and returns to their original shape, converting deformation energy into mechanical work or kinetic energy. Since springs are in a working environment where the load is constantly changing for a long time, manufacturers need to conduct strict factory tests on springs.

[0003] At present, spring testing is done manually by loading and unloading materials, and the test is completed by an automatic force measuring mechanism. The qualified and unqualified results are displayed on a display screen or lighted, and then manually sorted. The labor intensity of the workers is high, and material mixing may occur due to human errors. At the same time, the qualified springs need to be manually transported to the labeling equipment for the labeling process, which not only has low work efficiency, but also requires a large amount of manual operation.

[0004] For example, the automatic spring force testing and sorting machine disclosed in prior art 201820998355.8 can automatically sort the springs according to the system judgment results, but it still requires manual loading one by one, which has low work efficiency, high labor intensity, and does not have an automatic labeling function.

[0035] The loading tray 2 is used to regularly place a number of springs 15 to be tested;

[0036] The dynamometer 3 shown is used to test whether the elastic force of the spring 15 meets the requirements;

[0037] The manipulator 4 is used to grab the springs 15 to be tested one by one from the loading tray 2 and place them on the dynamometer 3 for testing, and to send the tested good springs 15 from the dynamometer 3 to the labeling mechanism 6 for labeling;

[0038] The printer 5 is used to print labels;

[0039] The labeling mechanism 6 is used to grab a label from the printer 5, attach it to the good product spring 15, and place it in the good product material box 7;

[0040] The defective product removing mechanism 8 is used to place defective products from the dynamometer 3 into the defective product material box 9 .

[0041] During operation: manually place the springs 15 to be tested on the loading tray 2 in an orderly manner, and then start the equipment. The robot 4 grabs the springs 15 to be tested from the loading tray 2 one by one and places them on the dynamometer 3 for testing. If it is a good spring 15, the robot 4 sends the tested good spring 15 from the dynamometer 3 to the labeling mechanism 6, and the labeling mechanism 6 grabs the label from the printer 5 and sticks it on the good spring 15, and places it in the good material box 7. If it is a defective spring 15, the defective product is directly placed in the defective material box 9 from the dynamometer 3 through the defective product material selection mechanism 8.

[0042] Further, if Figure 2 The robot 4 includes a robot arm 41 arranged on the machine platform 1, and a double-headed gripper assembly arranged at the driving end of the robot arm 41; the double-headed gripper assembly includes a mounting plate 42, and two first gripper cylinders 43 respectively arranged on the mounting plate 42 and placed in parallel.

[0043] The manipulator 4 of the utility model adopts a double-headed clamping claw assembly structure, after one of the first clamping claw cylinders 43 grabs a good spring 15, the other first clamping claw cylinder 43 can be immediately replaced with a spring to be tested 15, which greatly improves work efficiency.

[0045] When the dynamometer 3 detects that the spring 15 is a defective product, the defective product is placed in the defective product box 9 from the dynamometer 3 by driving the rod 83 through the defective product removing cylinder 82, wherein the guide groove 84 plays a guiding role to ensure that the defective spring 15 can accurately fall into the defective product box 9; in the utility model, the height of the defective product removing cylinder 82 on the defective product removing platform 81 is adjustable, which can reduce the processing accuracy and facilitate assembly and debugging.

[0046] Further, if Figure 4 The outlet of the printer 5 is provided with a label receiving mechanism 10; the label receiving mechanism 10 includes a receiving table 101 arranged on the machine table 1, a receiving cylinder 102 horizontally arranged on the receiving table 101 and with the driving end pointing to the outlet of the printer 5, and a receiving plate 103 horizontally arranged at the driving end of the receiving cylinder 102 and slightly lower than the outlet of the printer 5; a vacuum suction hole 104 is arranged on the receiving plate 103.

[0049] During operation: first, the linear module 62 drives the movable seat 63 to drive the first lifting cylinder 64 to be located directly above the label receiving mechanism 10, and then the first lifting cylinder 64 drives the vacuum suction head 65 to suck the label from the receiving plate 103, and finally the label is attached to the good spring 15.

The manipulator 4 does not need to wait during labeling, which greatly improves the work efficiency; then the vacuum suction head 65, driven by the linear module 62 and the first lifting cylinder 64, sticks the label on the good spring 15; finally, driven by the linear module 62 and the second lifting cylinder 66, the good spring 15 with a label is placed in the good material box 7 through the third clamping claw cylinder 67; when the third clamping claw cylinder 67 clamps the good spring 15, it will clamp the fitting position of the label and the good spring 15, so that the label is firmly attached to the surface of the good spring 15, thereby improving the fitting effect.

[0054] When loading, the springs 15 to be tested are manually placed one by one in the discharge hole 21, and then the loading tray 2 is placed on the machine table 1, and the universal positioning hole 22 and the positioning pin are used to achieve positioning; when testing springs 15 of different models, only different loading trays 2 need to be replaced.

[0055] Further, if Figure 6 The machine 1 is provided with a protective box 12; the front of the protective box 12 is provided with an opening, and the other sides are provided with openable protective windows 13 made of transparent material, which are not only convenient for observing the internal working conditions, but also convenient for maintenance; a group of safety gratings 14 are provided on both sides of the opening to play a safety protection role when loading and unloading.
