Description

Technical Field

[0001] This utility model belongs to the field of cylinder liner testing technology, specifically, it relates to a device for detecting deep grooves on the end face of large-diameter cylinder liners. Background Technology

[0002] Large-bore cylinder liners are mainly used in ship, generator set, and locomotive engines. These devices typically need to withstand high pressures and temperatures, thus placing strict requirements on the material and manufacturing process of the cylinder liners. Figure 1 The large-diameter cylinder liner shown has a circular cylindrical deep groove on its top surface. The width and depth of the cylindrical deep groove are marked, and these two process dimensions need to be inspected and controlled during production.

[0003] However, existing inspection methods typically require the use of tools such as calipers, which is relatively cumbersome and inefficient for batch inspections. Therefore, there is an urgent need to develop a deep groove inspection device for the end face of large-diameter cylinder liners to improve the efficiency of batch inspections. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting deep grooves on the end face of large-diameter cylinder liners, so as to improve the efficiency of batch detection of deep grooves on the end face of corresponding large-diameter cylinder liners.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for detecting deep grooves on the end face of a large-diameter cylinder liner includes a rectangular center block. A connecting rod is centrally located at the top of the rectangular center block, and a handle is connected to the top of the connecting rod. Probe 1 and Probe 2 are centrally located on the left and right sides of the rectangular center block, respectively, and Probe 3 is centrally located at the bottom. Probe 1, Probe 2, Probe 3, and the connecting rod are arranged in a cross shape on the rectangular center block. The diameter of Probe 1 is the lower limit of the width of the deep groove on the end face, and the length of Probe 1 is the lower limit of the depth of the deep groove on the end face. The diameter of Probe 2 is the lower limit of the width of the deep groove on the end face, and the length of Probe 2 is the upper limit of the depth of the deep groove on the end face. The diameter of Probe 3 is the upper limit of the width of the deep groove on the end face.

[0007] Preferably, the handle is a cross handle.

[0008] More preferably, the cross handle is covered with a wear-resistant and non-slip sleeve.

[0009] Preferably, the rectangular center block has a cube structure.

[0010] The working principle of this invention is as follows: During testing, the handle is held with one hand. If the third probe cannot be inserted into the deep groove on the end face of the large-diameter cylinder liner, it indicates that the width of the groove is less than the upper limit of the process requirement. If the first probe can be fully inserted into the deep groove, and slight shaking of the testing device reveals no gap between the probe and the contact surface of the rectangular center block, it indicates that both the width and depth of the deep groove are greater than the lower limit of the process requirement. If the second probe can be fully inserted into the deep groove, and slight shaking of the testing device reveals a certain gap between the probe and the contact surface of the rectangular testing platform, it indicates that the width of the deep groove is greater than the lower limit of the process requirement, while the depth is less than the upper limit of the process requirement.

[0011] If the above inspection process is met, the width and depth dimensions of the end face deep groove are both between the lower and upper limits of the process, and the processed end face deep groove is qualified; otherwise, if the above inspection process is not met, the processed end face deep groove is unqualified.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The structural design is simple and reasonable, and the operation is very convenient;

[0014] 2. The detection is accurate and efficient, and can meet the detection needs of mass production. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0021] Example

[0022] like Figures 1-3 As shown, this utility model provides a device for detecting deep grooves on the end face of a large-diameter cylinder liner, including a rectangular center block 1. A connecting rod 2 is centrally located at the top of the rectangular center block, and a cross handle 3 is connected to the top of the connecting rod. A probe 1 4 and a probe 2 5 are centrally located on the left and right sides of the rectangular center block, respectively, and a probe 3 6 is centrally located at the bottom. The probe 1, probe 2, probe 3, and the connecting rod are arranged in a cross shape on the rectangular center block. The diameter of probe 1 is the lower limit of the width of the deep groove on the end face, and the length of probe 1 is the lower limit of the depth of the deep groove on the end face. The diameter of probe 2 is the lower limit of the width of the deep groove on the end face, and the length of probe 2 is the upper limit of the depth of the deep groove on the end face. The diameter of probe 3 is the upper limit of the width of the deep groove on the end face.

[0023] In this embodiment, the cross handle is covered with a wear-resistant and non-slip sleeve (not shown in the figure), and the rectangular center block is a cube structure.

[0024] The working principle of this invention is as follows: During testing, the handle is held with one hand. If the third probe cannot be inserted into the deep groove on the end face of the large-diameter cylinder liner, it indicates that the width of the groove is less than the upper limit of the process requirement. If the first probe can be fully inserted into the deep groove, and slight shaking of the testing device reveals no gap between the probe and the contact surface of the rectangular center block, it indicates that both the width and depth of the deep groove are greater than the lower limit of the process requirement. If the second probe can be fully inserted into the deep groove, and slight shaking of the testing device reveals a certain gap between the probe and the contact surface of the rectangular testing platform, it indicates that the width of the deep groove is greater than the lower limit of the process requirement, while the depth is less than the upper limit of the process requirement.

[0025] If the above inspection process is met, the width and depth dimensions of the end face deep groove are both between the lower and upper limits of the process, and the processed end face deep groove is qualified; otherwise, if the above inspection process is not met, the processed end face deep groove is unqualified.

[0026] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
