DETAILED DESCRIPTION
[0046] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0047] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0048] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.
[0049] Embodiment 1:
[0050] like Figure 1 , Figure 2 As shown, an embodiment of the present application provides a brake pump assembly, including a workbench 1, a main pump body 2, an oil inlet pipe 3, an oil inlet port 4, a piston, a push rod and a return spring, and also includes: a buffer unit 5, which is installed in the oil inlet pipe 3; wherein the lower end of the buffer unit 5 is in contact with the oil inlet port 4.
[0051] Furthermore, the buffer unit 5 includes a buffer frame 6 fixedly installed in the oil inlet pipe 3; a buffer plate 7 fixedly installed in the buffer frame 6; and an oil inlet hole 8 arranged at the lower end of the buffer frame 6 and corresponding to the oil inlet port 4.
[0052] Furthermore, it also includes a plurality of oil inlet holes 9 which are evenly distributed on the buffer plate 7 .
[0053] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when adding oil inside the main body, the oil tank is first connected to the oil inlet pipe 3, and the oil outlet end of the oil tank is installed to the upper port of the buffer frame 6. The oil flows into the cavity of the buffer frame 6 and slowly falls to the lower end of the buffer plate 7 through the oil inlet holes 9 evenly distributed on the buffer plate 7. The setting of the oil inlet holes 9 disperses the impact force of the oil entering, and the oil enters the main pump body 2 along the oil inlet port from the oil inlet hole 8, making the oil flow more smooth.
[0054] Embodiment 2:
[0055] like Figure 3 , Figure 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a mounting base 10, which is fixedly mounted on the workbench 1; a guide rod 11, one end of which is fixedly connected to the mounting base 10; and a pair of clamping assemblies 12, which are movably mounted on the guide rod 11 respectively.
[0056] Furthermore, the clamping assembly 12 includes a slider 13, which is slidably mounted on the guide rod 11; a double-headed screw 14, which is rotatably mounted on the slider 13 and is electrically driven; and a pair of clamping blocks 15, which are respectively mounted on both ends of the double-headed screw 14 through threads.
[0057] Furthermore, it also includes a first fastening screw 16 which is installed on one side of the sliding block 13 and whose inner end abuts against the guide rod 11 ; and an anti-sliding block 17 which is fixedly connected to the inner side of the clamping block 15 .
[0058] In this embodiment of the present application, due to the adoption of the above-mentioned structure, in order to ensure the stability of the installation of the main pump body 2, the main pump body 2 is installed on the clamping block 15, and the spacing of the clamping assembly 12 can be adjusted according to the size of different pump bodies. The driving motor drives the double-headed screw 14 to rotate, and a pair of clamping blocks 15 simultaneously move toward the inside of the double-headed screw 14 and clamp the two sides of the main pump body 2. An anti-sliding block 17 is provided on the fitting surface of the clamping block 15 and the main pump body 2, which effectively avoids the main pump body 2 sliding in the clamping block 15 during use. The spacing of a pair of clamping blocks 15 can be adjusted simultaneously according to the rotation of the double-headed screw 14, so that the clamping block 15 can clamp the main pump bodies 2 of different diameters.
[0059] Furthermore, the lengths of the main pump body 2 are also different. The positions of the clamping assemblies 12 at both ends of the guide rod 11 can be adjusted according to the length of the main pump body 2. When the position needs to be adjusted, the first fastening screw 16 of the locking slider 13 is first loosened to make the first fastening screw 16 away from the outer wall of the guide rod 11, and the slider 13 is moved on the guide rod 11 according to the required size. When it moves to a position that can support the main pump body 2, the first fastening screw 16 is tightened again, and the inner end thereof needs to rest against the outer wall of the guide rod 11 to effectively limit the position of the slider 13. The above arrangement can not only ensure the installation stability of the main pump body 2, but also can install main pump bodies 2 of different specifications, further improving the use range of the clamping assembly 12.
[0060] Embodiment 3:
[0061] like Figure 3 , Figure 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a slide 18, which is arranged on the workbench 1; a moving block 19, which is slidably installed on the slide 18; a second fastening screw 20, which is installed on the moving block 19, and the inner end is against the bottom surface of the workbench 1; a tightening component 21, which is fixedly installed on the moving block 19.
[0062] Furthermore, the tightening assembly 21 includes a fixed seat 22, which is fixedly connected to the upper end of the moving block 19; a push rod 23, which is movably inserted into the fixed seat 22; an adjusting block 24, one end of which is rotatably connected to the fixed seat 22; and a connecting block 25, both ends of which are rotatably connected between the push rod 23 and the adjusting block 24.
[0063] In this embodiment of the present application, due to the adoption of the above-mentioned structure, after the main pump body 2 is installed on the workbench 1, it is necessary to tighten one end of the main pump body 2 to further ensure the stability of the main pump body 2, and the adjustment block 24 installed inside the fixing seat 22 is rotated inward by 90°, so that the connecting end of the adjustment block 24 pushes the rear end of the connecting block 25 to rotate. While the connecting block 25 rotates, the front end of the connecting block 25 moves the push rod 23 along the front side of the fixing seat 22, and the push rod 23 presses one end surface of the main pump body 2. 2 have different lengths. When it is necessary to tighten the main pump bodies 2 of different lengths, loosen the second fastening screw 20 that locks the moving block 19, and the inner end of the second fastening screw 20 is separated from the bottom surface of the workbench 1. The moving block 19 loses its locking force, and the moving block 19 is pushed to move left and right along the slideway 18. After the push rod 23 is tightened against one end surface of the main pump body 2, the second fastening screw 20 is tightened and abutted against the bottom surface of the workbench 1, which is convenient for manually moving the position of the tightening component 21 and adapting to main pump bodies 2 of various specifications.
