[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a rapid testing device for steering gear strength, including: a base plate 1, with main slide grooves 7 symmetrically opened on the upper surface of the base plate 1, an electromagnet 3 fixedly connected to the bottom of the inner cavity of the main slide groove 7 through a groove, and a main slider 2 slidably connected in the main slide groove 7, and a secondary slide groove 14 opened on the side of the base plate 1, with a secondary slider 13 slidably connected in the secondary slide groove 14, and the lower end of the mounting plate 10 fixedly connected to the surface of the secondary slider 13, a hydraulic cylinder 11 fixedly connected to the upper end of the mounting plate 10, and a test pressure head 9 fixedly connected to the telescopic rod of the hydraulic cylinder 11, while a clamping block 5 is fixedly connected to the upper surface of the main slider 2 by mounting bolts 4, and a steering gear body 6 is movably connected in the placement groove opened on the upper surface of the clamping block 5.

[0019] In this embodiment, the steering gear body 6 is placed in the placement groove on the upper surface of the clamping block 5, so that the steering gear body 6 can be stably placed on the base plate 1. When the hydraulic cylinder 11 is activated, the extension rod of the hydraulic cylinder 11 pushes the test pressure plate downward, and then the test pressure plate can exert corresponding pressure on the steering gear body 6, thereby quickly detecting the strength of the steering gear body 6. When the size and structure of the steering gear body 6 change, the electromagnet 3 is turned off, the fixed connection between the base and the main slider 2 is released, the main slider 2 is taken out and re-embedded into the corresponding main slide groove 7, and the position of the main slider 2 is adjusted. When the electromagnet 3 is turned on, the position of the clamping block 5 is adjusted. Then, the mounting bolt 4 is removed, the old clamping block 5 is removed, and the corresponding new clamping block 5 is fixedly connected to the upper surface of the main slider 2 by the mounting bolt 4. Therefore, the new steering gear body 6 with changes in size and structure can still be placed stably on the base plate 1. Thus, the device can also perform rapid strength testing on it. Furthermore, the mounting plate 10 is pushed to move along the length of the base plate 1 by the auxiliary slider 13, so that the test pressure plate can press different positions on the surface of the steering gear body 6, thereby improving the comprehensiveness of the device for the strength test of the steering gear body 6.

[0020] In a preferred embodiment, the base plate 1 has a rectangular structure, and multiple sets of main sliding grooves 7 are opened parallel and equally spaced along the length direction on the upper surface of the base plate 1. The multiple sets of main sliding grooves 7 are all long strip structures, and the end face of the main sliding groove 7 is a convex structure. At the same time, the length of the main sliding groove 7 is less than the width of the base plate 1.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The opening of multiple main slide grooves 7 allows the main slide block 2 and its corresponding clamping block 5 to be set at different positions on the surface of the base plate 1, thereby facilitating the stable placement of steering gear bodies 6 of different sizes and structures. At the same time, the main slide groove 7 only connects to one side of the surface of the base plate 1, which facilitates the loading and unloading of the main slide block 2.

[0022] In a preferred embodiment, the electromagnet 3 fixedly connected to the bottom of the inner cavity of the main slide groove 7 has a long strip structure, and the length of the electromagnet 3 is equal to the length of the main slide groove 7. The inner cavity size of the main slide groove 7 is adapted to the size of the main slider 2, and the end face of the main slider 2 has a convex structure.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The main slider 2 can be made of ferrous metal. After the electromagnet 3 is energized, it can attract and fix the main slider 2, thereby enhancing the stability of the fixed connection between the main slider 2 and the base plate 1. This facilitates the adjustment of the position of the clamping block 5 and avoids the problem of positional deviation of the steering body 6 during the test. At the same time, the dimensions of the main slider 2 and the main slide 7 are compatible, which can help enhance the stability of the main slider 2 and the clamping block 5 when they move.

[0024] As a preferred embodiment, two sets of positioning grooves are symmetrically opened at both ends of the upper surface of the main slider 2. Both sets of positioning grooves are rectangular in structure. A weight reduction groove is opened in the middle of the lower surface of the main slider 2, and the weight reduction groove is square in structure. At the same time, a screw hole is opened in the middle of the upper surface of the main slider 2.

[0025] In this embodiment, as Figure 1 and Figure 3 The weight reduction groove can effectively reduce the overall weight of the main slider 2, reduce the difficulty of workers moving it, and also help reduce the amount of material used, thus saving production costs.

[0026] In a preferred embodiment, the clamping block 5 has a concave structure, the placement groove on the upper surface of the clamping block 5 has an isosceles triangular structure, and the lower surface of the clamping block 5 is connected to the positioning block 12 relative to the positioning groove. Both sets of positioning blocks 12 have a rectangular structure. At the same time, a through groove is opened at the bottom of the placement groove, and the mounting bolt 4 passes through the through groove and is screwed into the screw hole opened in the main slider 2.

[0027] In this embodiment, as Figure 2 and Figure 3The positioning block 12 and the positioning groove are matched in size, which can help enhance the stability of the fixed connection between the clamping block 5 and the main slider 2 of different sizes and structures. The opening of the through groove allows the mounting bolt 4 to help the clamping block 5 to be fixedly connected to the upper surface of the main slider 2, and also avoids the mounting bolt 4 from interfering with the stable placement of the steering gear body 6.

[0028] In a preferred embodiment, the secondary slide 14 has an elongated structure, the length of the secondary slide 14 is equal to the length of the base plate 1, the end face of the secondary slide 14 has an isosceles trapezoidal structure, and the edges of the secondary slide 14 have an arc-shaped structure. The inner cavity size of the secondary slide 14 is adapted to the size of the secondary slider 13, and a friction layer 15 is fixedly connected to the outer side of the secondary slider 13.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The friction layer 15 can be made of rubber, which can help enhance the frictional resistance between the secondary slide groove 14 and the secondary slider 13. Moreover, the size of the secondary slide groove 14 and the secondary slider 13 are compatible, which can also help enhance the stability of the secondary slider 13 and the mounting plate 10 when they move.

[0030] In a preferred embodiment, the mounting plate 10 has an L-shaped structure. The upper bent portion of the mounting plate 10 is fixedly connected to the hydraulic cylinder 11, and the inner side of the upper bent portion of the mounting plate 10 is fixedly connected to the reinforcing block 8. The reinforcing block 8 has a right-angled triangular structure, and a hollow groove is opened in the middle of the reinforcing block 8. At the same time, the thickness of the mounting plate 10 is less than the length of the auxiliary slider 13.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 A pressure sensor assembly is fixedly connected to the surface of the hydraulic cylinder 11. The pressure sensor is electrically connected to an external PLC assembly, which can detect the pressure applied by the test plate to the steering gear body 6 in real time, thereby improving the accuracy of the strength test of the steering gear body 6. At the same time, the setting of the reinforcing block 8 can help enhance the overall structural strength of the mounting plate 10 and reduce the probability of bending deformation of the mounting plate 10 during use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
