DETAILED DESCRIPTION

[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] Embodiment 1: This embodiment is intended to promote the solution of the problem that in the prior art, when most test devices test the oil rail, they mostly use manual fixing to clamp it, and then test it. In this case, manual operation may not only lead to insufficient clamping, but also waste time. Please refer to Figure 1-Figure 6 A leakage test and clamping device for the left and right parts of an oil rail comprises a fixing plate 110 and an oil rail 190. A placement plate 200 is fixedly connected in the middle of the fixing plate 110. The oil rail 190 is placed in the middle of the placement plate 200. A fixing plate 210 is snap-connected to one end of the oil rail 190. A snap-connecting groove 430 is opened in the middle of the fixing plate 210. A snap-connecting groove 240 is connected to the side of the snap-connecting groove 430. A snap-connecting assembly 250 is snap-connected in the middle of the snap-connecting groove 430. A fixing assembly 440 is installed in the middle of the snap-connecting groove 430.

[0025] The other end of the oil rail 190 is in contact with a push plate 180, and the push plate 180 is fixedly installed with a mounting frame 160 by a fixing bolt 170. The side of the mounting frame 160 is fixedly connected with a connecting block 150, and the side of the connecting block 150 is fixedly connected with a mounting plate 130. The bottom of the mounting plate 130 is fixedly installed with a fixing plate 110 by a mounting bolt 140, and the side of the mounting plate 130 is fixedly installed with a cylinder 120. The side of the fixing plate 210 is fixedly installed with a supporting frame 220 by a fixing bolt 230, and the supporting frame 220 is fixedly connected with the fixing plate 110. The fixing assembly 440 includes a telescopic ring 300 installed in the middle of the engaging groove 430, and the telescopic ring 300 is installed in the middle of the mounting ring 290.

[0026] When the device is in use, the staff can directly engage the oil rail 190 with the placement plate, and then push the push plate 180 through the cylinder 120 to engage the oil rail 190 with the placement plate more firmly. When the push plate 180 is pushed, the connecting plate will be engaged with the slot 240 due to the squeezing of the telescopic ring 300. During the engagement process, the slider 410 will squeeze the telescopic spring 400, and then the slider 410 can be engaged with the slot 240.

[0027] When encountering oil rails 190 of different specifications, the oil rails 190 of different specifications can be clamped and fixed by setting the telescopic ring 300. During the clamping process, since the diameter is greater than the diameter of the clamping ring 310, when the oil rail 190 and the clamping ring 310 are clamped, the telescopic ring 300 will be squeezed, and then through the squeezing of the oil rail 190, the arc column 320 will be expanded and contracted in the limit groove 330, and the oil rail 190 will be clamped after the expansion and contraction is completed.

[0028] In this embodiment: when the oil rail 190 needs to be tested, the worker first engages the oil rail 190 with the placement plate, and then pushes the cylinder 120 to make the oil rail 190 and the placement plate more firmly engaged. After the cylinder 120 finishes pushing, the oil rail 190 can be tested for leakage through other devices. The engaging assembly 250 is mostly arranged, and when the oil rail 190 is engaged, the oil rail 190 and the placement plate are engaged and connected as much as possible, so as to avoid the problem of inaccurate results in subsequent tests. In this equipment, the staff only needs to place the oil rail 190 on the placement plate, and the staff does not need to manually fix it, thereby reflecting the convenience of the device when operating.

[0029] Embodiment 2: This embodiment is intended to facilitate solving the problem of automatically performing clamping tests on oil rails of different specifications. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 6 The telescopic ring 300 includes a limiting groove 330 opened in the middle of the mounting ring 290, a limiting spring 340 is installed in the middle of the limiting groove 330, one end of the limiting spring 340 is fixedly connected to the end of the limiting groove 330, and the other end of the limiting spring 340 is fixedly connected to the arc column 320.

[0030] The arc column 320 is inserted in the middle of the limiting groove 330, and the side of the limiting groove 330 is fixedly connected with the arc plate 370. The side of the limiting groove 330 is provided with a connecting groove 350, and the bottom of the connecting groove 350 is fixedly connected to the end of the arc column 320. A snap ring 310 is provided on the side of the mounting ring 290, and the side of the snap ring 310 is fixedly connected with the telescopic rod 280, and the telescopic rod 280 is inserted in the middle of the mounting ring 290.

[0031] The end of the telescopic rod 280 is fixedly connected to the connecting tube 270, the end of the connecting tube 270 is fixedly installed with the connecting rod 260, the end of the connecting rod 260 is installed with a clamping assembly 250, the clamping assembly 250 includes a telescopic groove 380 opened in the middle of the connecting rod 260, the middle of the telescopic groove 380 is fixedly installed with a back plate 390, the middle of the telescopic groove 380 is installed with a telescopic spring 400, one end of the telescopic spring 400 is fixedly connected to the back plate 390, and the other end of the telescopic spring 400 is fixedly connected to a slider 410.

[0032] In this embodiment: when the oil rail 190 is engaged and fixed with the placement plate, the telescopic ring 300 is provided so that when encountering oil rails 190 of different specifications, they can be clamped. During the clamping process, since the diameter of the telescopic ring 300 is smaller than the diameter of the oil rail 190, when engaging, the oil rail 190 has a larger diameter, which will push the arc column 320 to expand and contract in the limit groove 330. When the arc column 320 expands and contracts, the arc column 320 will pull the limit spring 340. Then, after the test of the oil rail 190 is completed, the arc column 320 will be reset due to the elastic force of the spring, so that the specifications of the equipment during testing are as comprehensive as possible.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
