Description

Technical Field

[0001] This utility model relates to the field of spring testing technology, and more specifically, to a spring force testing device. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under external force and return to their original shape after the force is removed. After spring production, a batch of springs needs to be sampled for elasticity testing. This testing requires elasticity testing equipment. For example, patent CN212482844U discloses a device for easily testing spring elasticity. The spring to be tested is vertically placed inside a positioning cylinder. Then, a controller starts a motor, which rotates a rotating rod. This rotates two sets of threaded rods that mesh with the rotating rod via bevel gears, causing the pressure plate to move downwards until the extrusion plate touches the top of the spring. The motor continues to press the extrusion plate down, compressing the spring. At this point, a pressure sensor detects the change in spring elasticity.

[0003] The above-mentioned device is simple in structure and easy to operate. It can quickly test the spring force, thereby improving the working efficiency of the device. The correction rod and positioning cylinder can provide safety protection during the spring force test. However, it is inconvenient to test springs of different specifications. At the same time, if the spring is not placed correctly when the extrusion plate presses down on the spring, it is easy to cause the spring to bend during the press, which will affect the stability of the spring pressing.

[0013] In a preferred embodiment, the annular pressure detector is a commercially available annular washer-type pressure sensor NF115, and the number of rotating connectors is multiple, arranged in an array on both sides of the transverse central axis in the main viewing direction of the door.

[0014] In a preferred embodiment, the vertical slide bar extends through the end face of the support ear plate, and there are two of each vertical slide bar and support ear plate, which are mirror images of each other on both sides of the vertical central axis in the main viewing direction of the detection box.

At the same time, the limit rod will be inserted into the interior of the limit adapter block, and when the spring is pressed and breaks, it will prevent the broken spring from flying outwards, reducing the safety hazards to the staff.

Detailed Implementation

[0026] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0027] This utility model provides a spring force detection device, such as... Figure 1 , 2 As shown in Figure 3, the test box 1 is provided with a hydraulic telescopic rod 3 at its upper end. The lower side of the inner end face of the test box 1 is provided with a test support plate 10. The upper end of the test support plate 10 is provided with a circular adapter hole 9.

[0028] The circular adapter hole 9 has a support block 11 inside, and a support plate 12 is provided on the outer side of the upper end of the support block 11. The support block 11 can be easily disassembled and separated from the circular adapter hole 9. During installation, the support block 11 is aligned and inserted into the interior of the circular adapter hole 9. Therefore, the installation and replacement of the support block 11 are relatively convenient. This allows the spring of the corresponding specification to be locked on the upper end of the limiting adapter block 22. The outer end face of the limiting adapter block 22 will fit against the inner end face of the spring. Since there is no gap between the outer end face of the limiting adapter block 22 and the inner end face of the spring... The spring has no space to wobble on the outer end face of the limiting adapter block 22, thus effectively increasing the stability during spring testing. The telescopic shaft of the hydraulic telescopic rod 3 is provided with a limiting mounting plate 13 inside the testing box 1. A door 2 is provided on one side of the outer end face of the testing box 1. A rotating connector 4 is provided at the joint between the testing box 1 and the door 2. When testing the spring, the door 2 protects the spring, allowing the spring to be tested in a sealed space, thereby preventing the spring from flying outwards and affecting the safety of the staff when it breaks during testing.

[0029] A rotating handle 5 is provided on one side of the outer end face of the box door 2, which can be used to lock and open the box door 2. The lower end of the detection box 1 is provided with a support foot 6. A vertical slide bar 8 is provided on one side of the upper end of the detection support plate 10. A scale guard plate 7 is provided on one side of the vertical slide bar 8 on the upper end of the detection support plate 10. According to the specifications of the spring, the operator installs the support blocks 11 of different specifications on the upper end of the circular adapter hole 9. Then the spring can be installed on the upper end of the limiting adapter block 22. Then the operator drives the hydraulic telescopic rod 3 through the external control device, which will drive the limiting mounting plate 13 to descend through the telescopic shaft, so that the detection pressing plate 17 presses on the top of the spring.

[0030] The telescopic shaft of the hydraulic telescopic rod 3 passes through the end face of the detection box 1 and extends into its interior. The outer side of the limiting mounting plate 13 is provided with a support ear plate 14. The hydraulic telescopic rod 3 is electrically connected to the external control equipment. The inner end face of the circular adapter hole 9 in the top view direction is adapted to the outer end face of the support block 11 in the top view direction.

[0031] The number of the rotating connectors 4 is multiple, and they are arranged in an array on both sides of the horizontal central axis in the main view direction of the door 2. The vertical slide rods 8 are arranged through the end face of the support ear plate 14. There are two of each of the vertical slide rods 8 and the support ear plate 14, and they are arranged in a mirror image on both sides of the vertical central axis in the main view direction of the detection box 1.

[0032] The scale guard plate 7 is L-shaped in the main viewing direction. There are two scale guard plates 7, and they are mirror images of each other on both sides of the vertical central axis in the main viewing direction of the detection box 1, which makes it easy to observe the position of the spring compression according to the scale on one side of the scale guard plate 7.

[0033] like Figure 4 and 5 As shown, a limiting adapter block 22 is provided in the middle of the upper end of the support plate 12, a threaded limiting sleeve 15 is provided in the middle of the lower end of the limiting mounting plate 13, and an annular pressure detector 16 is provided on the outside of the threaded limiting sleeve 15 at the lower end of the limiting mounting plate 13.

[0034] The limiting adapter block 22 and the support block 11 have a limiting slot 21 in the middle. The threaded limiting sleeve 15 has a connecting rod 19 inside. The lower end of the connecting rod 19 has a limiting insert 20. The outer end face of the connecting rod 19 has a detection pressing plate 17. When the limiting mounting plate 13 drives the annular pressure detector 16 and the detection pressing plate 17 to move downward, the pressing block 18 will press against the annular pressure detector 16 to detect the spring force. Then the limiting insert 20 is inserted into the limiting slot 21 to prevent the spring from splashing outward when it breaks under pressure, thereby reducing the safety of the spring force detection.

[0035] The upper end of the detection pressing plate 17 is provided with a pressing block 18, the inner end face of the threaded limiting sleeve 15 is connected to the upper side of the outer end face of the connecting rod 19 by a thread, and the annular pressure detector 16 is a commercially available annular washer type pressure sensor NF115.
