[0002] Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. They are used in the tuning circuit of transistor radios, the coupling circuit and bypass circuit of color TVs, etc. The capacitors are generally equipped with a shell on the outside. There are many types of shells, and plastic shells are one of them. In the production process of plastic shells, they need to be tested in many ways, including high temperature resistance and pressure resistance, which requires the use of detection devices.
[0003] In order to ensure the stability of the plastic shell during the detection process, the existing detection device needs to limit it first, and the plastic shell is limited directly by two top blocks. Since the plastic shell is a special-shaped structure, the limiting mechanism of the existing technology can only clamp the plastic shell at a single point, and its stability is poor. During the detection process, the plastic shell is easy to move, resulting in errors in the detection. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0024] Example 1
[0025] like Figure 1 As shown;
[0026] A rapid detection device for a vehicle-standard capacitor plastic shell comprises a support 1.
[0027] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the currently existing detection device, in order to ensure the stability of the plastic shell during the detection process, it is necessary to limit it first, and the plastic shell is limited directly by two top blocks. Since the plastic shell is a special-shaped structure, the limiting mechanism of the prior art can only clamp the plastic shell at a single point, and its stability is poor. During the detection process, the plastic shell is easy to move, resulting in errors in the detection." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a limiting component 3 is added on this basis.
[0028] like Figure 1-5 As shown in the figure;
[0029] In combination with the above content, in order to improve the stability of the plastic shell limit, it also includes a downward pressure detection component 2 arranged on the top of the support 1, and a limit component 3 fixed on the downward pressure detection component 2;
[0030] The limit assembly 3 includes a lower pressure plate 31 fixed on the lower pressure detection assembly 2, and sliding rods 32 that slide up and down are arranged at both ends of the lower pressure plate 31 through sliding holes. A limiting mechanism 33 is fixed at the bottom end of the sliding rod 32, and a spring 34 is sleeved between the sliding rods 32 at the top of the limiting mechanism 33. A pressure head 35 is fixed at the bottom of the lower pressure plate 31.
[0031] In an optional embodiment, the two limiting mechanisms 33 have the same size and structure and are symmetrically arranged on the left and right sides. The limiting mechanism 33 includes a fixed block 331, and a U-shaped limiting sliding cavity 332 is opened inside the fixed block 331. The two ends of the U-shaped limiting sliding cavity 332 are respectively provided with a left top rod 333 and a right top rod 334 that slide back and forth. The interior of the U-shaped limiting sliding cavity 332 between the left top rod 333 and the right top rod 334 is filled with a ball 335.
[0032] In this embodiment: the left push rod 333 slides inward inside the U-shaped limiting sliding cavity 332, and the movement of the ball 335 inside the U-shaped limiting sliding cavity 332 pushes the right push rod 334 at the other end of the U-shaped limiting sliding cavity 332 to move outward. Conversely, the right push rod 334 moves inward while the left push rod 333 moves outward.
[0033] In an optional embodiment, the downward pressure detection component 2 includes a pair of support rods 21 and a cylinder 22 fixed on the support 1, and a fixed plate 23 is fixed on the top of the two support rods 21. The two ends of the fixed plate 23 are provided with sliding columns 24 that slide up and down through sliding tubes. The top of the two sliding columns 24 is fixed with a top plate 25. The bottom center of the top plate 25 is connected to the piston rod of the cylinder 22, and the bottom ends of the two sliding columns 24 are respectively fixed at the two ends of the top of the lower pressure plate 31.
[0034] In this embodiment, the cylinder 22 drives the top plate 25 to move downward, and then pushes the upper limit assembly 3 to move downward through the slide column 24.
[0035] Working principle of this utility model:
[0036] The plastic shell is placed on the support 1, and the cylinder 22 drives the top plate 25 to move downward, and then pushes the upper limit assembly 3 to move downward through the sliding column 24. At this time, the plastic shell is limited by the limiting mechanism 33. When any one of the left top rod 333 or the right top rod 334 of the limiting mechanism 33 fits with the outermost point of the plastic shell, it slides inward inside the U-shaped limiting sliding cavity 332, and at the same time pushes the ball 335 to roll inside the U-shaped limiting sliding cavity 332, and pushes the right top rod 334 inside the other end of the U-shaped limiting sliding cavity 332 to slide outward through the ball 335 until it fits with another point of the plastic shell, finally completing the limitation of the plastic shell, and the cylinder 22 continues to move to drive the pressure head 35 to perform a pressure test on the fixed plastic shell.
[0037] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
