[0030] The technical solutions provided by the embodiments of the present utility model will be described in detail below with reference to the drawings.

[0031] As Figures 1 to 4 shown, the quick solenoid valve pulling force detection tooling of this embodiment includes a tensile testing machine upper platform 1, a connecting sleeve 2, a preloading connecting piece 3, a spring plunger 4, a solenoid valve 5, a positioning block 6, and a base 7. The bottom of the tensile testing machine upper platform 1 is fixedly connected with the connecting sleeve 2, and the bottom of the connecting sleeve 2 is connected with the preloading connecting piece 3. As Figures 5 to 7 shown, the preloading connecting piece 3 includes a connecting body 31, an upper connecting end 32, and a lower extending end 33. The upper part of the connecting body 31 is fixedly connected with the upper connecting end 32, and the lower part is symmetrically fixedly connected with the lower extending ends 33. A mating groove is formed in the middle of the bottom end of the connecting body 31. The upper connecting end 32 is fixedly connected with the connecting sleeve 2. A through accommodating cavity 34 is formed inside the preloading connecting piece 3, and a spring plunger 4 is installed in the accommodating cavity 34. As Figure 8 、 Figure 9 shown, preferably, the spring plunger 4 is an internal hexagonal threaded spring plunger 4. The ball head 41 of the spring plunger 4 extends out of the connecting body 31 and is located in the mating groove. A T-shaped through groove is formed between the mating groove and the two symmetrically arranged lower extending ends 33. A positioning block 6 is arranged on the upper part of the solenoid valve 5, and the lower part is fixed on the base 7. As Figure 10 、 Figure 11 shown, the positioning block 6 is a hollow boss structure and has an upper cavity 61 and a lower cavity 62 that communicate with each other inside. The upper part of the solenoid valve 5 is accommodated in the lower cavity 62, and the moving spool 51 of the solenoid valve 5 and the lower extending ends 33 are both located in the upper cavity 61. The upper part of the moving spool 51 is located in the through groove and the top end abuts against the ball head 41.

[0032] Among them, as Figures 1 to 4 shown, the connecting sleeve 2 adopts a tooling chuck structure. The tooling chuck structure includes a fixed end and chucks 22 symmetrically arranged on both sides of the fixed end. The fixed end is fixedly connected to the upper platform 1 of the tensile testing machine. A locking screw 21 is connected between the two chucks 22, and the two chucks 22 clamp and fix the upper connecting end 32 through the locking screw 21.

[0033] In order to better achieve the fixed connection between the connecting sleeve 2 and the preloading connector 3 and improve the stability of their connection, as Figure 4 shown, arc grooves 23 adapted to the outer side wall of the upper connecting end 32 are respectively formed on the opposite sides of the two chucks 22.

[0034] Specifically, fixing blocks 71 are symmetrically and fixedly connected to the base 7. Limiting grooves are respectively formed on the opposite sides of the two fixing blocks 71. The fixing boss 52 in the middle of the solenoid valve 5 is located in the limiting groove. A fixing screw 8 is threadedly connected to each fixing block 71, and the head of the fixing screw 8 abuts against the upper surface of the fixing boss 52. Moreover, the fixing blocks 71 are fixed to the base 7 by symmetrically arranged socket head screws.

[0035] In addition, the base 7 is fixedly connected to the lower platform of the tensile testing machine by symmetrically arranged connecting screws 9.

[0036] When the quick solenoid valve pulling force detection tooling of this embodiment is in use, first, the connecting sleeve 2 is fixedly connected to the upper platform 1 of the tensile testing machine by screws. The upper connecting end 32 of the preloading connector 3 is extended between the two chucks 22, and the upper connecting end 32 is clamped and fixed through the locking screw 21 to realize the connection between the preloading connector 3 and the connecting sleeve 2. Then, the height of the upper platform 1 of the tensile testing machine is adjusted until the upper part of the moving spool 51 of the solenoid valve 5 to be tested is flush with the upper part of the through groove horizontally. At this time, the solenoid valve 5 to be tested is translated so that the solenoid valve 5 to be tested moves between the two fixing blocks 71, and the fixing boss 52 in the middle of the solenoid valve 5 is located in the limiting groove. By tightening the fixing screw 8, the head of the fixing screw 8 abuts against the upper surface of the fixing boss 52 to realize the fixation of the position of the solenoid valve 5 to be tested. Moreover, after translating the solenoid valve 5 to be tested, the upper part of the moving spool 51 can be located in the through groove. Then, the positioning block 6 is placed on the solenoid valve 5 to be tested. At this time, the moving spool 51 is located in the upper cavity 61 of the positioning block 6, and the upper part of the moving spool 51 extends out of the upper cavity 61. By adjusting the lowering of the upper platform 1 of the tensile testing machine, the lower extending end 33 of the preloading connector 3 is driven to extend into the upper cavity 61, and the ball head 41 can abut against the moving spool 51 and move downward together until the moving spool 51 is slightly stressed. Among them, when positioning the height of the moving spool 51, the function of the spring plunger 4 is to stably connect the moving spool 51. At this time, the solenoid valve 5 to be tested is powered on, and the detection reading of the tensile testing machine is read. At this time, the reading is the electromagnetic force of the moving iron core of the solenoid valve 5 to be tested at a specific height. After the power-on is completed, the solenoid valve 5 to be tested is removed, and the test is over.

[0037] When using the quick solenoid valve drawing force detection tooling of this embodiment to conduct electromagnetic force detection, the detection data is more stable and accurate, the detection is convenient, and the positioning accuracy is high.

[0038] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
