[0015] Compared with the prior art, the beneficial effects of this utility model are: the novel cap breakpoint value testing device not only facilitates the lifting and lowering of the buffer plate and protects the cap, but also limits the rack.
[0016] (1) By setting up a rack, gear, servo motor, fixed plate and rotating shaft, the cap is placed on the placement slot. After it is placed, the servo motor is started. The servo motor drives the gear to rotate through the rotating shaft. Since the gear and rack cooperate with each other, the rotation of the gear can drive the rack to lower the fixed plate and buffer plate, so that the buffer plate can be lowered to the top of the cap to limit and fix the cap, preventing the cap from moving accidentally and affecting the accuracy of the test.

[0024] 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.
[0025] Please see Figure 1-4 The present invention provides an embodiment of a novel cap breakpoint value testing device, comprising a base 1, a nitrogen tank 17 disposed on the right side of the top of the base 1, a support block 2 fixedly connected to the left side of the top of the base 1, a support seat 3 disposed at the middle position of the top of the support block 2, a placement groove 14 disposed at the top of the support seat 3, an installation plate 7 fixedly connected to the left side of the rear end of the top of the base 1, a protective shell 6 installed at the front end of the installation plate 7, and a lifting structure disposed inside the protective shell 6.
[0026] The lifting structure includes a rack 9 and a gear 10. A rotating shaft 18 is movably connected to the right side inside the protective shell 6. A servo motor 11 is installed at the front end of the protective shell 6. A gear 10 is fixedly connected to the outside of the rotating shaft 18. A rack 9 is provided on the left side inside the protective shell 6. A fixing plate 12 is fixedly connected to the bottom end of the rack 9.
[0027] The rack 9 is located on the left side of the gear 10. The rack 9 and the gear 10 are meshed. The output end of the servo motor 11 is fixedly connected to the front end of the rotating shaft 18 through a coupling. The left and right sides of the support base 3 are fixedly connected to the connecting pipe 4 and the pipe 15. The top of the connecting pipe 4 is equipped with a pressure gauge 5. The top of the right side of the pipe 15 is equipped with a solenoid valve 16. The right side of the pipe 15 is connected to the nitrogen tank 17.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, place the cap on the placement slot 14. After placement, start the servo motor 11. The servo motor 11 drives the gear 10 to rotate through the rotating shaft 18. Since the gear 10 and the rack 9 cooperate with each other, the rotation of the gear 10 can cause the rack 9 to drive the fixing plate 12 and the buffer plate 20 to descend. This allows the buffer plate 20 to descend to the top of the cap and limit and fix the cap, preventing the cap from moving accidentally and affecting the accuracy of the test.
[0029] A buffer plate 20 is provided at the bottom of the fixed plate 12. Buffer springs 13 are fixedly connected to the left and right sides between the fixed plate 12 and the buffer plate 20. A damper 19 is provided inside the buffer spring 13. The damper 19 is installed between the fixed plate 12 and the buffer plate 20. The buffer plate 20 is located at the top of the placement groove 14. A buffer pad 21 is fixedly connected to the bottom of the buffer plate 20. The buffer springs 13 are symmetrically distributed about the vertical center line of the buffer plate 20.
[0030] Specifically, such as Figure 1 and Figure 3 As shown, when the fixed plate 12 and the buffer plate 20 descend, the buffer spring 13 can automatically cushion the cap with its elasticity to prevent damage to the cap when it is fixed in place. The damper 19 inside the buffer spring 13 can limit the buffer spring 13 to prevent the buffer spring 13 from causing the support block 2 to sway left and right. The buffer pad 21 at the bottom of the buffer plate 20 can further protect the cap under test.
[0031] A connecting block 22 is fixedly connected to the left side of the rack 9. A limiting slider 23 is fixedly connected to the left side of the connecting block 22. Ball bearings 24 are provided at the upper and lower ends inside the limiting slider 23. A limiting groove 8 is fixedly connected to the left side inside the protective shell 6. The limiting slider 23 is located inside the limiting groove 8. The limiting slider 23 slides up and down inside the limiting groove 8, and the ball bearings 24 roll inside the limiting slider 23.
[0032] Specifically, such as Figure 1 and Figure 4 As shown, when the rack 9 is raised and lowered, the connecting block 22 on the left side of the rack 9 will slide up and down inside the limiting slider 23 in the limiting groove 8, thereby limiting the rack 9, improving the stability of the rack 9's raising and lowering, and preventing the tooth block on one side of the rack 9 from being misaligned with the tooth block outside the gear 10. The ball 24 inside the limiting slider 23 can reduce the friction between the limiting groove 8 and the limiting slider 23.
[0033] Working Principle: In use, the cap is placed on the placement slot 14. After placement, the servo motor 11 is started. The servo motor 11 drives the gear 10 to rotate via the shaft 18. Since the gear 10 and rack 9 cooperate, the rotation of the gear 10 causes the rack 9 to lower the fixing plate 12 and buffer plate 20. This allows the buffer plate 20 to descend to the top of the cap, limiting and fixing it to prevent accidental movement and ensuring test accuracy. When the fixing plate 12 and buffer plate 20 descend, the buffer spring 13 automatically cushions the cap with its elasticity, preventing damage during the cap's limiting and fixing process. The damper 19 inside the spring 13 can limit the buffer spring 13 to prevent the buffer spring 13 from causing the support block 2 to sway left and right. The buffer pad 21 at the bottom of the buffer plate 20 can further protect the test cap. When the rack 9 is raised and lowered, the connecting block 22 on the left side of the rack 9 will slide up and down inside the limiting slider 23 in the limiting groove 8, thereby limiting the rack 9, improving the stability of the rack 9's raising and lowering, and preventing the tooth block on one side of the rack 9 from being misaligned with the tooth block outside the gear 10. After the limit is set, the solenoid valve 16 is opened to allow the gas to impact the CID of the cap, and then the pressure gauge 5 is used to determine whether the weld point of the cap is broken.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
