Description

Technical Field

[0001] The utility model relates to the technical field of oil nozzles, in particular to an oil nozzle detection tool. Background Art

[0002] The nozzle inspection tooling includes a base, a nozzle and a pressure head. The nozzle mouth passes through the base, and the connection part of the nozzle is exposed at the top of the base. The pressure head is placed at the top of the base, and a through hole is opened in the middle of the pressure head. The concentricity between the nozzle and the base is judged by whether the connection part can pass through the through hole. When placing the pressure head, it is easy for the pressure head to collide with the nozzle and the base. To prevent serious collision, the pressure head is usually not quenched, resulting in severe wear of the pressure head after a period of use and a short service life. At the same time, some iron filings dropped by the pressure head will be pressed into the base, affecting the balance of the nozzle during positioning, reducing the detection accuracy.

[0023] First embodiment:

[0024] This embodiment discloses a nozzle inspection tool.

[0025] Figure 1 It is a structural schematic diagram of the oil nozzle detection tooling of the utility model. Figure 2 This is a schematic diagram of the structure of the oil nozzle detection tooling of the utility model after the oil nozzle is installed. Figure 1 and Figure 2 As shown, the oil nozzle inspection tool is used for the oil nozzle 4 , and the oil nozzle 4 includes a first connecting portion 41 and a mouth portion 42 . The outer diameter of the first connecting portion 41 is greater than the outer diameter of the mouth portion 42 .

[0026] The oil nozzle detection tooling comprises a base 1 , a limit sleeve 3 and a pressure head 5 .

[0027] The base 1 includes a first hole 11 and a second hole 12. The first hole 11 is opened at the upper end of the base 1, and the second hole 12 is opened at the lower end of the base 1 and communicates with the first hole 11. Exemplarily, the first hole 11 and the second hole 12 are opened in the middle of the base 1. The mouth 42 of the oil nozzle 4 passes through the second hole 12, and the first connecting part 41 of the oil nozzle 4 passes through the limiting sleeve 3 and abuts against the bottom of the first hole 11. The upper end of the first connecting part 41 is higher than the base 1.

[0028] The limiting sleeve 3 is slidably disposed in the first hole 11, and the lower end is elastically connected to the bottom of the first hole 11. Exemplarily, a fourth hole 31 is provided in the middle of the limiting sleeve 3, and the first connecting portion 41 passes through the fourth hole 31 and does not protrude from the upper end of the fourth hole 31, so as to prevent the pressing head 5 from directly colliding with the base 1 and the first connecting portion 41.

[0029] The pressure head 5 is arranged at the upper end of the limiting sleeve 3, and the lower end is provided with a fifth hole 51. Exemplarily, the fifth hole 51 is provided in the middle of the pressure head 5, and the oil nozzle 4, the base 1, the limiting sleeve 3 and the pressure head 5 are coaxially arranged. The pressure head 5 is made of quenched material to improve the service life of the pressure head 5. Preferably, the pressure head 5 includes a sixth hole 52, and the sixth hole 52 is provided at the lower end of the fifth hole 51, and the inner diameter is larger than the inner diameter of the fifth hole 51. Among them, the upper end of the limiting sleeve 3 is inserted into the sixth hole 52, so that the limiting sleeve 3 and the pressure head 5 are positioned first to reduce collision.

[0030] Further, the base 1 includes a cushion block 2, and the cushion block 2 is arranged at the bottom of the first hole 11. The mouth 42 passes through the cushion block 2, the lower end of the first connecting portion 41 abuts against the cushion block 2, and the lower end of the limiting sleeve 3 is elastically connected to the cushion block 2. Exemplarily, a seventh hole 22 is opened in the middle of the cushion block 2, and the mouth 42 passes through the seventh hole 22. A sealing surface is formed between the cushion block 2 and the bottom of the first hole 11, reducing the risk of impurities such as iron filings falling into the bottom of the first hole 11 and ensuring the accuracy of detection.

[0031] Further, the nozzle inspection tooling includes an elastic member 6, the upper end of the elastic member 6 is connected to the limit sleeve 3, and the lower end is connected to the cushion block 2. Exemplarily, the cushion block 2 includes an extension portion 21, and the extension portion 21 is arranged at the upper end of the cushion block 2. Among them, the elastic member 6 is sleeved on the outside of the extension portion 21, and the lower end of the first connecting portion 41 abuts against the extension portion 21. The extension portion 21 limits the elastic member 6 to ensure that the pressure head 5 and the limit sleeve 3 can be stably pressed down and reset.

[0032] In this embodiment, the pressure head 5 is placed on the limit sleeve 3, the oil nozzle 4 is placed in the base 1, the upper end of the first connecting part 41 is higher than the base 1 and lower than the limit sleeve 3, the pressure head 5 presses down the limit sleeve 3, and the concentricity is judged by whether the upper end of the first connecting part 41 is exposed from the limit sleeve 3 and passes through the fifth hole 51, thereby avoiding the possibility of the pressure head 5 colliding with the base 1 and the oil nozzle 4 when placed, and improving the service life of the oil nozzle detection tooling.

[0033] Second embodiment:

[0034] Based on the first embodiment, the second embodiment further optimizes and refines the limiting sleeve 3 and the base 1 .

[0035] The limiting sleeve 3 includes a groove 32, which is opened on the side of the limiting sleeve 3. The base 1 includes a positioning screw 7, which includes a second connecting portion 71 and a protrusion 72. The second connecting portion 71 is fixed to the side of the base 1, and the protrusion 72 is arranged on the inner side of the second connecting portion 71 and extends into the groove 32. Exemplarily, the base 1 includes a third hole 13, which is opened on the side of the base 1. The second connecting portion 71 is threadedly connected to the third hole 13.

[0036] In this embodiment, the positioning screw 7 on the side of the base 1 is inserted into the groove 32 on the side of the limit sleeve 3 to limit the upward and downward sliding stroke of the limit sleeve 3, thereby reducing the possibility of the pressure head 5 being pressed down too much and colliding with the oil nozzle 4, and the possibility of the limit sleeve 3 being reset too quickly and flying out, thereby improving the reliability of the oil nozzle detection tooling.
