Utility Model Content

[0003] In view of this, in order to solve the problems of the prior art, the utility model provides a structurally improved inspection fixture for automobile engine oil pipes, which can perform position inspection on oil pipes with relatively complex structures according to their structures.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A detection jig for an automobile engine oil pipe comprises a base plate, a first pressure head assembly fixedly arranged on the base plate, a second pressure head assembly, a first detection assembly and a second detection assembly, wherein the first pressure head assembly is used to fix the oil pipe, the second pressure head assembly is used to detect the position of the top end of the oil pipe, the bottom of the oil pipe is connected to the first detection assembly, the first detection assembly is used to detect the bottom size of the oil pipe, and the second detection assembly is used to detect the position of the first position of the oil pipe.

[0006] The detection fixture of the utility model is a special inspection device specially used to detect the mouth size and position quality of the tested product (oil pipe). The method used to detect the mouth size is based on the go / no-go gauge detection method. The position detection method is to first calculate the actual maximum contour of the product according to the position requirement and the dimensional tolerance, and then process parts with the same size contour in the first detection component and the second detection component according to the contour, and then determine whether there is interference between the deformed product and the contours of the parts processed in the first detection component and the second detection component, so as to realize the detection of the product position.

[0007] According to some preferred implementation aspects of the utility model, the first detection assembly includes a first fixed block and a second fixed block fixedly connected to one end of the first fixed block, and the bottom surfaces of the first fixed block and the second fixed block are both fixedly connected to the bottom plate.

[0008] According to some preferred implementation aspects of the present invention, the first fixing block is perpendicular to the second fixing block, and the top surface of the second fixing block is located above the top surface of the first fixing block.

[0009] According to some preferred implementation aspects of the utility model, a through hole is provided on the first fixing block that runs through the thickness direction thereof, and the through hole is used for inserting the bottom of the oil pipe; a receiving groove is provided downwardly on the top of the second fixing block, and the receiving groove passes through a side edge of the top surface of the second fixing block close to the oil pipe, and the receiving groove is used to accommodate the mounting portion of the oil pipe. In some embodiments of the utility model, during testing, the bottom end (mouth) of the oil pipe is first inserted into the through hole on the first fixing block, and the size of the mouth of the oil pipe is first tested.

[0027] Furthermore, if Figure 2 As shown, the first pressing head assembly 2 includes a support platform 21, a clamping member 22, and a first pressing head 23 fixedly connected to the clamping member 22. The support platform 21 is fixedly connected to the bottom plate 1, and the clamping member 22 is installed on the support platform 21. The clamping member 22 is used to clamp the first pressing head 23. The first pressing head 23 is used to press the mounting portion 61 of the oil pipe 6 into the receiving groove 421 to keep the oil pipe 6 fixed. In this embodiment, the clamping member 22 is preferably a vertical clamp to facilitate clamping the first pressing head 23.

If there is no problem with the installation, it means that there is no problem with the position of the first position of the oil pipe 6. Finally, press the second pressure head 33. If the detection hole 331 on the second pressure head 33 can face the protrusion 62 at the top of the oil pipe 6, it means that there is no problem with the position of the top of the oil pipe 6. Finally, it is concluded that there is no problem with the size and position of the mouth of the oil pipe 6.
