Description

Technical Field

[0001] The invention belongs to the technical field of piston detection, and in particular relates to a precision piston detection device and a detection method. Background Art

[0002] The piston is a reciprocating part in the cylinder block of a car engine. The basic structure of the piston can be divided into the top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the type of combustion chamber selected.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0052] Embodiment 1:

[0053] This embodiment provides a precision piston detection device, including:

[0054] Base 1;

[0055] A driving device, the driving device comprises a slide rail 21, a first slide 22 and a second slide 23, and a fixing frame 3 is disposed on the first slide 22 and the second slide 23;

[0132] Embodiment 9:

[0133] This embodiment provides a precision piston detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0134] The protective sleeve 9 is arranged in the sliding cavity 53211 and cooperates with the movable sliding sleeve 5322 .

[0135] It can be seen from this embodiment that by providing a protective sleeve 9 in the sliding cavity 53211 to protect the fixed sliding sleeve 5321 , it is helpful to extend the service life of the fixed sliding sleeve 5321 and the movable sliding sleeve 5322 .

[0136] Embodiment 10:

[0137] This embodiment provides a detection method for precision piston detection equipment, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0138] S1, the igniter 7 continues to burn after the piston is assembled on the steel sleeve 8, and the burning time is set to 10 seconds;

[0139] S2. During explosion, the gas provides thrust to the clamped piston, and the phase clamping assembly 532 absorbs the force on the piston.

[0140] It can be seen from the present embodiment that when preparing to carry out piston inspection, the piston is first connected to the steel sleeves 8 at both ends of the generating chamber 4111, and then the igniter 7 is started. After the generating chamber 4111 burns, two situations occur. In the first situation, a seal is formed between the piston and the steel sleeve 8, and the igniter 7 cannot be ignited normally. In the second situation, the piston fails to form a seal with the steel sleeve 8, and air continues to enter the generating chamber 4111, and the igniter 7 works normally. If the second situation occurs during use, it means that the piston size is unqualified or the surface of the steel sleeve 8 is worn and needs to be replaced, which helps to improve the inspection effect and facilitates inspection and maintenance.

[0141] After confirming the seal between the piston and the steel sleeve 8, the piston is inspected. The piston is displaced toward the two ends of the generating chamber 4111 due to the combustion and explosion in the generating chamber 4111. During the displacement, the phase clamping assembly 532 will resist the force on the piston rod, thereby absorbing and buffering the impact force to achieve a protective effect.

[0142] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
