Description

Technical Field

[0001] This utility model relates to the field of spring tension measurement technology, specifically a precision spring measuring device. Background Technology

[0002] A spring is a mechanical component that can undergo elastic deformation under the action of external force and return to its original shape after the external force is removed. It is usually made of elastic materials (such as steel, copper alloys, rubber, etc.) and has functions such as storing energy, buffering vibration, and controlling motion. Spring tension measurement is an experimental method used to measure the performance of a spring under force, mainly used to evaluate key parameters such as spring tension, stiffness, elastic limit, and fatigue life.

[0003] Existing spring tension measuring devices have certain shortcomings in practical use: the travel of the slide rail in existing tension measuring devices is fixed, which makes it impossible to accurately measure the maximum tension that springs with tension greater than the travel of the slide rail, thus affecting the final measurement results. Based on the shortcomings of existing technology, this utility model designs a precision spring measuring device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a precision spring measuring device with the advantage of adjustable measuring device stroke.

[0005] This utility model provides the following technical solution: a precision spring measuring device, comprising a base, with support seats fixedly installed on both sides of the top of the base, a slide rail structure fixedly installed inside the two support seats, a driving structure fixedly installed on the top of the base, and a fixing plate fixedly installed inside the two support seats; the slide rail structure includes a movable slide rail, which is slidably connected to the support seats, and a sliding plate is slidably installed inside the movable slide rail; a tension measuring instrument is fixedly installed on the top of the movable slide rail, and a pulling component is provided at the bottom of the tension measuring instrument, with one end of the bottom of the pulling component being fixedly connected to the sliding plate; the driving structure includes a threaded rod, which is rotatably connected to the base, and a handle is fixedly installed on the top of the threaded rod; a movable plate is threadedly installed on the outer surface of the threaded rod, and the movable plate is fixedly connected to the movable slide rail.

[0006] As a preferred embodiment of this utility model, a fixing seat is fixedly installed on one side of the outer surface of the fixing plate and the sliding plate, and a pin is installed inside the two fixing seats by internal threads.

[0007] As a preferred embodiment of this utility model, a protective structure is fixedly installed on one side of the outer surface of the two support seats. The protective structure includes two hinged seats and two rotating rods.

[0008] As a preferred embodiment of this utility model, the two hinged seats are internally hinged with folding plates.

[0009] As a preferred embodiment of this utility model, a pull-out plate is slidably installed inside the folding plate.

[0010] As a preferred embodiment of this utility model, the pull-out plate has a groove inside.

[0011] As a preferred embodiment of this utility model, the two rotating rods are rotatably connected to the support base.

[0012] As a preferred embodiment of this utility model, stop bars are fixedly installed at the ends of the two rotating rods.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This precision spring measuring device, through a slide rail structure and a drive structure, addresses different springs. When the original travel of the sliding plate within the movable slide rail is less than the maximum travel of the spring under tension, rotating the handle causes the threaded rod to rotate, causing the movable plate to drive the movable slide rail upward within the support base. At this time, the travel between the movable slide rail and the fixed plate increases. Since the sliding plate and the movable slide rail are slidably connected, the distance between the sliding plate and the fixed plate remains unchanged. After connecting the pulling component to the sliding plate, the spring can be fixed between the fixed plate and the sliding plate for tension measurement. This achieves the purpose of adjustable travel of the measuring device and improves the accuracy of measurement.

[0015] 2. This precision spring measuring device, through a protective structure, allows for the folding of a folding plate during tension measurement, ensuring it fits against the surface of the support base. After the pull-out plate is fully pulled out from inside the folding plate, the folding plate and the pull-out plate can completely shield the slide rail structure. At this time, folding the side stops to fit against the folding plate prevents the spring from resetting and falling during the measurement process, thus preventing the spring from accidentally popping out during spring tension measurement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A precision spring measuring device includes a base 1, with support seats 2 fixedly installed on both sides of the top of the base 1. A slide rail structure 3 is fixedly installed inside the two support seats 2. A drive structure 4 is fixedly installed on the top of the base 1. A fixing plate 21 is fixedly installed inside the two support seats 2. The slide rail structure 3 includes a movable slide rail 31, which is slidably connected to the support seats 2. A sliding plate 32 is slidably installed inside the movable slide rail 31. A tension measuring instrument 33 is fixedly installed on the top of the movable slide rail 31. A pulling component 34 is provided at the bottom of the tension measuring instrument 33. One end of the bottom of the pulling component 34 can be fixedly connected to the sliding plate 32. The drive structure 4 includes a threaded rod 41, which is rotatably connected to the base 1. A throttle 42 is fixedly installed on the top of the threaded rod 41. A movable plate 43 is threadedly installed on the outer surface of the threaded rod 41. The movable plate 43 is fixedly connected to the movable slide rail 31.

[0024] Please see Figure 2-4 A fixing seat 35 is fixedly installed on one side of the outer surface of the fixing plate 21 and the sliding plate 32, and a pin 36 is installed inside the two fixing seats 35 by internal threads.

[0025] When installing the spring, the two pins 36 are pulled out from inside the fixing seat 35, and the two ends of the spring are inserted into the fixing seat 35 and fixed again by the pins 36.

[0026] Please see Figure 1 and Figure 5A protective structure 5 is fixedly installed on one side of the outer surface of each of the two support bases 2. The protective structure 5 includes two hinged seats 51 and two rotating rods 55. A folding plate 52 is hingedly installed inside each of the two hinged seats 51. A pull-out plate 53 is slidably installed inside the folding plate 52. A pull groove 54 is formed inside the pull-out plate 53. The two rotating rods 55 are rotatably connected to the support bases 2. A stop bar 56 is fixedly installed at the end of each of the two rotating rods 55.

[0027] By folding the folding plate 52 to make it fit against the surface of the support base 2, and then fully pulling the pull plate 53 out from inside the folding plate 52, the slide rail structure 3 can be completely covered by the folding plate 52 and the pull plate 53. At this time, by folding the two side stops 56 to make them fit against the folding plate 52, it can be prevented from resetting and falling down during the measurement process.

[0028] Working principle: When using a precision spring measuring device, firstly, the two pins 36 are pulled out from inside the fixed base 35. Then, the two ends of the spring are inserted into the fixed base 35 and secured again by the pins 36. Next, the pulling assembly 34 is connected to the sliding plate 32, and the tension measuring instrument 33 is activated to measure the tension. During the tension measurement process, the folding plate 52 is folded to fit against the surface of the support base 2. After the pull plate 53 is fully pulled out from inside the folding plate 52, the folding plate 52 and the pull plate 53 can completely shield the slide rail structure 3. At this time, folding the two side stops 56 to fit against the folding plate 52 prevents it from resetting and falling during the measurement process. This avoids the spring from accidentally popping out during spring tension measurement. When dealing with different springs, if the original travel of the sliding plate 32 within the movable slide rail 31 is less than the maximum travel of the spring, by turning the handle 42, the threaded rod 41 rotates and causes the movable plate 43 to drive the movable slide rail 31 to move upward inside the support base 2. At this time, the travel between the movable slide rail 31 and the fixed plate 21 increases. Since the sliding plate 32 is slidably connected to the movable slide rail 31, the distance between the sliding plate 32 and the fixed plate 21 remains unchanged. After connecting the pulling component 34 to the sliding plate 32, the spring can be fixed between the fixed plate 21 and the sliding plate 32 for tension measurement.
