Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile axles, in particular to a quickly detachable axle housing protective device for protecting the axle housing inner cavity and surface for installation, thereby preventing the surface and inner cavity from being damaged during shot blasting. Background Art
[0002] As axle products have increasingly higher requirements for the cleanliness of the inner cavity of the bridge housing and the appearance quality of the surface, protection is required to ensure that the inner cavity and surface of the bridge housing are not damaged or contaminated during actual production. The conventional protection method is to make simple steel plates and bolts, etc., which has poor protection effect and requires the installation of a large number of bolts during protection, which makes disassembly and installation more troublesome. In addition, there are many product models and structures. The simple protection method requires the production of many types of protective gear, which cannot be universal and has a high protection cost. Summary of the Invention
[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing technologies and provide a quickly detachable bridge housing protection device, which mainly solves the problems of insufficient protection of the existing bridge housing installation cavity and surface, the inability to quickly disassemble the protection means and the high cost.
[0004] The technical solution provided by the present invention is: a quickly detachable bridge housing protection device, including a pressure plate, the special feature of which is that a handle is fixed on the pressure plate; two sheaths are symmetrically fixed on the pressure plate; a rubber pad and an inner pressure plate are provided under the pressure plate, and the three are fixedly connected; a spring pressure plate is provided under the inner pressure plate, and the spring pressure plate is connected to the pressure plate through a tightening bolt and a nut; the tightening bolt passes through the sheath and is connected to the nut, and the nut is located above the sheath.
[0005] Furthermore, a plurality of reinforcing ribs are evenly fixed on the pressing plate.
[0006] Furthermore, the inner pressure plate and the rubber pad are fixedly connected to the pressure plate through nuts, bolts, and spring washers.
[0007] The beneficial effects of the present invention are: 1. It is fixed with bolts and can be quickly disassembled, reducing the labor intensity and production time of operators; 2. It can be universal, saving protection costs; 3. It makes the protection of the inner cavity and surface of the bridge housing simpler, saving disassembly time and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the present invention; Figure 2 yes Figure 1 Attached view.
[0009] Among them, 1 pressure plate, 2 inner pressure plate, 3 spring pressure plate, 4 nut, 5 bolt, 6 spring washer, 7 rubber pad, 8 tightening bolt, 9 nut, 10 handle, 11 reinforcement rib, 12 sheath. DETAILED DESCRIPTION
[0010] For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings; the embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.
[0011] like Figure 1 、 2 As shown, a quickly detachable bridge housing protective device includes a pressure plate 1, an inner pressure plate 2, a spring pressure plate 3, a nut 4, a bolt 5, a spring washer 6, a rubber pad 7, a tightening bolt 8, a nut 9, a handle 10, a reinforcing rib 11, and a sheath 12; a handle 10, two sheaths 12, and a reinforcing rib 11 are welded on the pressure plate 1, two handles 10 are symmetrically welded on the pressure plate 1, and the two handles 10 are located on the outside of the pressure plate 1. There can also be multiple handles 10; multiple reinforcing ribs 11 are evenly welded on the pressure plate 1 to increase its rigidity; two sheaths 12 are welded to the reinforcing rib 11 to form a reinforcing rib Internally, a hole for installing the sleeve 12 is pre-processed on the pressure plate 1; a rubber pad 7 and an inner pressure plate 2 are installed under the pressure plate 1, and the inner pressure plate 2 and the rubber pad 7 are fixedly connected to the pressure plate 1 through nuts 4, bolts 5, and spring washers 6, and the rubber pad 7 is located between the pressure plate 1 and the inner pressure plate 2; a spring pressure plate 3 is installed under the inner pressure plate 2, and the spring pressure plate 3 is connected to the pressure plate 1 through clamping bolts 8 and nuts 9, and the clamping bolts 8 pass through the sleeve 12 and are connected to the nuts 9, and the nuts 9 are located above the sleeve 12. The main function of the sleeve 12 is to protect the connection rigidity of the clamping bolts 8 and nuts 9 to the pressure plate 1.
[0012] The present invention provides a quickly detachable bridge housing protection device. When in use, the spring pressure plate 3 is placed in the inner cavity of the workpiece, the nut 9 is tightened, and the spring pressure plate 3 is pulled up to contact the edge of the inner cavity. After the clamping force is increased, the inner pressure plate 2 and the rubber pad 7 are in complete contact with the surface of the workpiece. In this way, the inner cavity and surface of the workpiece are completely protected to form a closed space; during shot blasting, the shot blasting sand can only hit the surface of the pressure plate 1, thereby protecting the surface and inner cavity of the workpiece.
[0013] It should be understood that any technical features not elaborated in detail in this specification belong to the prior art. Although the embodiments of the present invention are described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments, which are merely illustrative and not restrictive.
