Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and more specifically, to a quick spring length measuring tool. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under external force and returns to its original shape after the force is removed. Springs come in a wide variety of types; based on shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] A search revealed a Chinese patent with patent number CN204902719U: a spring length measuring device, comprising a base, a baffle, a slide rail, a seat, a clamp, a scale, and a support. The base has the baffle, slide rail, and support arranged sequentially from front to back. A support rod is mounted on the support and baffle, and a scale is mounted on the support rod. The seat is mounted on the slide rail, and a clamp is located at the front end of the seat. During operation, the clamp is manually moved until the rear end of the spring is in close contact with the clamp to measure the spring length. However, when moving the clamp to the rear end of the spring, the spring easily deforms and pops upwards due to its elasticity, leading to inaccurate measurements. Therefore, an improved, faster spring length measuring tool is needed. Utility Model Content

Detailed Implementation

[0037] 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.

[0038] like Figure 1-4 As shown, this utility model proposes an embodiment of a quick spring length measuring tool, including: a measuring base 1, a guide rod frame 2 fixedly connected to the top of the measuring base 1, and a movable groove 6 opened on the top of the measuring base 1.

[0039] Adjust the threaded rod 7, which can rotate inside the movable groove 6.

[0040] The adjusting motor 8 is fixedly connected to the measuring base 1, and its output shaft is fixedly connected to the adjusting threaded rod 7. A measuring ruler 21 is fixedly connected to the top of the measuring base 1, which makes it easy for the user to observe the length of the spring. The spring is only in the gap between the clamping frame 3 and the guide rod frame 1. The adjusting motor 8 drives the adjusting threaded rod 7 to rotate, thereby driving the clamping frame 3 to move, which can complete the maximum compression of the spring.

[0041] In this embodiment, it also includes a clamping frame 3, which is sleeved on the surface of the guide rod frame 2 and can move on the top of the measuring seat 1.

[0042] Adjustable clamping plate 4 can be raised and lowered inside clamping frame 3. Clamping frame 3 has a lifting groove 9 inside, and adjustable clamping plate 4 can move inside the lifting groove 9. When the lower pressure plate 5 presses springs of different specifications, the adjustable clamping plate 4 can be pressed into the lifting groove 9 appropriately according to the spring specifications so as to adapt to the usage requirements.

[0043] The reset spring 10 connects the clamping frame 3 to the adjusting clamping plate 4. When the adjusting clamping plate 4 is not squeezed, it can be pulled to automatically reset, ensuring the clamping effect on the spring and preventing the spring from flying off due to squeezing.

[0044] Adjusting threaded block 11 is fixedly connected to the bottom of clamping frame 3 and threadedly connected to adjusting threaded rod 7. It can drive clamping frame 3 to move as adjusting threaded rod 7 rotates.

[0045] In this embodiment, an adjustment groove 12 is provided on the left side of the clamping frame 3.

[0046] The bidirectional threaded rod 13 rotates inside the adjusting groove 12.

[0047] Adjusting plate 14 is threadedly connected to bidirectional threaded rod 13, so that the two adjusting plates 14 can move synchronously to complete the operation of moving closer to each other and moving further away from each other.

[0048] The conversion motor 15 has its output shaft fixedly connected to the bidirectional threaded rod 13. When the conversion motor 15 rotates, the two adjusting plates 14 move closer to each other under the drive of the bidirectional threaded rod 13, clamping the spring to prevent it from deforming and popping out to both sides due to compression.

[0049] A guide groove 16 is provided on the left side of the clamping frame 3 and above the adjustment groove 12.

[0050] The guide block 17 is located inside the guide groove 16. It guides the movement direction of the adjusting plate 14 and supports the adjusting plate 14, ensuring the stability of the movement of the adjusting plate 14 and preventing the adjusting plate 14 from rotating with the rotation of the bidirectional threaded rod 13.

[0051] In this embodiment, it also includes a lower pressure plate 5, which can be raised and lowered above the measuring seat 1. A support frame 18 is fixedly connected to the top of the measuring seat 1.

[0052] The guide rod 19 is fixedly connected to the top of the lower pressure plate 5 and can move inside the support frame 18. While guiding the movement direction of the lower pressure plate 5, it also ensures the stability of the lower pressure plate 5 as it descends.

[0053] The lifting push rod 20 connects the support frame 18 to the lower pressure plate 5. The lifting push rod 20 pushes the lower pressure plate 5 down, which can flatten the spring and prevent it from deforming and popping upward due to compression. Through the combination of the above implementation methods, the accuracy of measurement is greatly improved.

[0054] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0055] This utility model provides a quick spring length measuring tool. In use, the spring is placed in the gap between the clamping frame 3 and the guide rod frame 2. The adjusting motor 8 rotates, and under the drive of the adjusting threaded rod 7, the clamping frame 3 compresses the spring to the maximum degree. The switching motor 15 rotates, causing the adjusting plates 14 to move closer to each other, clamping the spring and preventing it from deforming and popping out to both sides due to compression. The lifting push rod 20 pushes the lower pressure plate 5 down, pressing the top of the spring to prevent it from deforming and popping out upwards due to compression.

[0056] In summary, this quick spring length measuring tool, through the cooperation of the measuring base 1, guide rod frame 2, clamping frame 3, adjusting clamping plate 4, and lower pressure plate 5, solves the problems mentioned in the background art.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
