Description

Technical Field

[0001] The utility model relates to a spring detection device, in particular to a spring processing detection device applied to the field of spring production. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. The elasticity of springs needs to be tested during the production process.

[0003] When testing the elasticity of a spring, most existing testing devices for springs fix the bottom of the spring and then apply pressure on the top of the spring to cause the spring to deform in the vertical direction, thereby testing the elasticity of the spring. However, during the testing process, the spring is prone to horizontal deformation, which not only leads to inaccurate test results, but also easily damages the spring, making it inconvenient for staff to use. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that when performing elasticity testing on a spring, the spring is prone to produce horizontal deformation after being subjected to pressure, thereby causing inaccurate spring elasticity testing results.

The end of the adjusting handle away from the shaft is rotatably connected to the fixed rod, and the end of the crank away from the shaft is rotatably connected to the front end of the circular plate. The front end of the mounting strip located above is fixedly connected to a lifting plate, and the bottom of the lifting plate is fixedly connected to a pressure plate through the mounting rod. The front end of the mounting strip located below is fixedly connected to a fixing plate, and the upper end of the fixing plate is fixedly connected to a pressure platform, and the upper end of the fixing plate is rotatably connected to a double-headed screw, and the top of the double-headed screw is fixedly passed through the pressure platform, and the upper and lower ends of the outer ring of the double-headed screw are threadedly sleeved with mounting blocks, and the outer ring of the mounting block is rotatably connected to multiple rotating rods, and the corresponding ends of the rotating rods at the upper and lower ends are rotatably connected to an arc plate.

[0006] In the above-mentioned detection device for spring processing, springs of different sizes can be limited in the horizontal direction, which effectively avoids the spring from being deformed in the horizontal direction during detection, thereby improving the accuracy of the detection result.

[0007] As a further improvement of the present application, a display screen is fixedly mounted on the front end of the pressure platform, and the display screen is electrically connected to the pressure platform.

[0008] As a further improvement of the present application, the threads at the upper and lower ends of the outer ring of the double-headed screw have opposite rotation directions, and the lower end of the double-headed screw passes through the fixed plate and is fixedly connected to the turntable.

[0012] To sum up, in actual application, the spring to be tested is sleeved on the outer surface of the arc plate, and the turntable is rotated to rotate the double-headed screw, so that the two mounting blocks move toward the center of the double-headed screw at the same time, driving the arc plate to move outward until it contacts the inner side of the spring, and then starting the motor to drive the circular plate to rotate an appropriate angle, so that the crank moves inward, thereby driving the shaft rod to rotate, and the adjusting handle rotates with the shaft rod as the center of the circle, driving the fixed rod to move outward, thereby moving the mounting bar inward, causing the fixed plate and the pressure plate to move toward the center of the operating table at the same time, and the pressure plate contacts the spring, thereby causing the spring to deform in the vertical direction. The pressure platform can detect the pressure generated by the spring deformation and transmit it to the display screen for display, which can effectively avoid the spring from deforming in the horizontal direction, improve the accuracy of detection, and facilitate use by staff.
