Description

Technical Field

[0001] The utility model relates to the technical field of spring checking tools, in particular to a spring checking tool. Background Art

[0002] Spring gauges are instruments used to test springs. After the springs are produced, they must pass rigorous testing before they can be put into use.

[0003] At present, the tension, pressure, displacement, stiffness, etc. of the spring are tested and analyzed by a spring testing machine. The spring is placed on a placement seat of the spring testing machine, the spring is compressed by a pressure block, and the data is recorded and analyzed by the spring testing machine.

[0004] However, currently the spring is only placed on the placement seat manually, which cannot ensure that the spring is placed in the center position, and the position of the spring cannot be made consistent during repeated inspections. As a result, when pressed down, the force and deformation of the spring during the compression process may be inconsistent, affecting the accuracy of the inspection. At the same time, there is a risk of the spring flying out when compressed, so a spring inspection fixture is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model embodiment discloses a spring checking tool.

[0023] according to Figure 1-Figure 4 As shown, it includes a spring detector 1, a placement seat 4 is fixedly connected to the top of the spring detector 1, a pressure head 302 is arranged on the spring detector 1, the pressure head 302 is located above the placement seat 4, and the driving structure on the spring detector 1 can drive the pressure head 302 to move up and down. The spring detector 1, the placement seat 4 and the pressure head 302 are all existing known technologies and are not described in detail here;

[0024] Two fixed seats 6 are fixedly arranged on the top of the spring tester 1, and the two fixed seats 6 are respectively arranged on both sides of the placement seat 4, and the two fixed seats 6 are symmetrically arranged. A sliding seat 503 is slidably arranged on the fixed seat 6, and a connecting seat 502 is fixedly arranged on the upper end of the sliding seat 503. A pushing seat 5 is fixedly arranged on the side of the connecting seat 502 away from the sliding seat 503, and the pushing seat 5 is arranged in an arc shape. The two pushing seats 5 are symmetrically arranged, and a contact seat 501 is fixedly arranged on the top of the pushing seat 5. The two contact seats 501 are symmetrically arranged, and an inclined surface 504 is arranged on the side where the two contact seats 501 are close to each other, and a limiting spring 602 is fixedly connected to the side of the sliding seat 503 away from the placement seat 4. The two pushing seats 5 are used to center and limit the spring to be tested. When in use, first pull the two pushing seats 5 and separate them, and compress the limiting spring 602 at the same time. Then, after the spring to be tested is placed on the placing seat 4, release the pushing seat 5. Under the action of the limiting spring 602, the two pushing seats 5 are brought close to each other, and the spring to be tested is squeezed between the two pushing seats 5. The spring to be tested can be squeezed at the center position on the placing seat 4, so that the spring can be placed at the same position on the placing seat 4 during repeated testing, so as to avoid the stress condition and the like of the spring during the compression process when the spring is placed at different positions. The deformation conditions may be inconsistent and affect the detection accuracy. During the detection, the pressure head 302 on the spring tester 1 moves downward, and the pressure head 302 will first contact the inclined surfaces 504 of the two contact seats 501. When the pressure head 302 squeezes the two contact seats 501, it can drive the two push seats 5 to move away from each other, so that the push seats 5 are moved away from under the pressure head 302, making it easier for the pressure head 302 to move downward to contact and squeeze the spring to be tested. When the pressure head 302 squeezes the spring to be tested, the two push seats 5 are still located on both sides of the spring to be tested, which can prevent the spring to be tested from flying out after being squeezed and deformed, and has higher safety.

[0025] A fixed rod 601 is fixedly connected inside the fixed seat 6, the sliding seat 503 is slidably connected to the adjacent fixed rod 601, and an adjusting seat 603 is also slidably connected to the fixed rod 601. A limit spring 602 is sleeved on the outside of the fixed rod 601, and both ends of the limit spring 602 are fixedly connected to the sliding seat 503 and the adjusting seat 603 respectively.

[0026] The adjusting seat 603 extends upward to the top of the fixed seat 6, and a plug-in seat 604 is plugged into the top of the adjusting seat 603. The plug-in seat 604 can move up and down relative to the adjusting seat 603. A plurality of slots 605 are provided on the upper end surface of the fixed seat 6. The plug-in seat 604 is plugged into and matched with the slots 605. By plugging the plug-in seat 604 into the adjusting seat 603 and the slots 605 at the same time, the position of the adjusting seat 603 can be fixed, and the plug-in seat 604 can be pulled upward to make the plug-in seat 604 and the slots 605 move in a straight line. Separate, then move the position of the adjustment seat 603 so that the plug-in seat 604 is aligned with another slot 605, and then move the plug-in seat 604 downward to make it plugged into the slot 605, the position of the adjustment seat 603 can be adjusted. After the position of the adjustment seat 603 is changed, the compression degree of the limit spring 602 will also change, thereby changing the thrust of the limit spring 602 on the sliding seat 503, the connecting seat 502 and the pushing seat 5, so as to facilitate the adjustment of the clamping force of the pushing seat 5 on the spring to be tested.

[0027] Working principle: When it is necessary to test the spring to be tested, first pull apart the two push seats 5 and compress the limit spring 602, then place the spring to be tested on the placement seat 4, release the push seat 5, and under the action of the limit spring 602, the two push seats 5 are brought closer to each other, and the spring to be tested is squeezed between the two push seats 5. The spring to be tested can be squeezed at the center position on the placement seat 4, so that when repeated testing is performed, the spring to be tested can be placed at the same position on the placement seat 4 to avoid the possibility that the force and deformation of the spring during the compression process may be different when the spring is placed at different positions. In order to solve the problem of inconsistency affecting the detection accuracy, the pressure head 302 on the spring tester 1 is moved downward. The pressure head 302 will first contact the inclined surfaces 504 of the two contact seats 501. When the pressure head 302 squeezes the two contact seats 501, it can drive the two push seats 5 to move away from each other, so that the push seats 5 move away from under the pressure head 302. The pressure head 302 continues to move downward to squeeze the spring to be tested. The spring tester 1 records and analyzes the data. During the detection process, the two push seats 5 are still located on both sides of the spring to be tested, which can prevent the spring to be tested from flying out after being squeezed and deformed, and has higher safety.
