Description

Technical Field

[0001] This utility model relates to the field of bridge housing production technology, and in particular to a bridge housing triangular plate grinding device. Background Technology

[0002] Automotive axle housings can be classified into three types according to their manufacturing processes: integral cast axle housings, steel plate stamping and welding axle housings, and expanded steel plate axle housings. Among these, steel plate stamping and welding axle housings are the most widely used. A steel plate stamping and welding axle housing consists of an upper axle plate, a lower axle plate, a leaf spring seat, a half-shaft sleeve, a rear cover, and a main reducer housing. The upper axle plate, lower axle plate, triangular plate, leaf spring seat, and half-shaft sleeve are welded together to form a welded drive axle housing. It has advantages such as light weight, good impact resistance, and low cost.

[0003] Before welding, the two arc-shaped connecting surfaces of the triangular plate need to be ground. The current grinding method is: the worker holds the triangular plate with pliers in one hand and grinds it with a hand-held grinder in the other hand. During the grinding process, grinding debris will be scattered everywhere, affecting the workshop environment. In addition, the safety of hand-held grinding cannot be guaranteed, and there are potential production hazards. Summary of the Invention

Slot. Detailed Implementation

[0013] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0014] like Figure 1-5As shown, this utility model includes a fixed base 6, on which a motor is fixedly mounted. The back plate of the cylindrical protective cover 3 is fixed to the housing of the motor. The conveying shaft 16 of the motor passes through the back plate, and a grinding brush 15 is mounted on the conveying shaft 16. The grinding brush 15 is located inside the cylindrical protective cover 3. A chip discharge port 4 is provided at the bottom of the cylindrical protective cover 3, and a dust removal hood 1 is installed at the port of the cylindrical protective cover 3. The dust removal hood 1 is connected to an industrial vacuum cleaner. A feeding port 17 is provided on the side wall of the cylindrical protective cover 3, and a feeding mechanism is provided on one side of the cylindrical protective cover 3. The feeding mechanism carries a triangular plate 13 in and out of the feeding port 17 and uses the grinding brush 15 for grinding.

[0015] In this embodiment, the feeding mechanism includes a support plate 7 vertically fixed to the fixed base 6, two support rods 8 vertically fixed to the support plate 7, a base 9 of the linear slide rail fixed to the upper ends of the two support rods 8, a sleeve 18 fixed to the slider 10 of the linear slide rail, a connecting rod 11 passing through the sleeve 18, and a mounting block 12 fixed to one end of the connecting rod 11 near the cylindrical protective cover 3. A slot 21 for partially embedding a triangular plate 13 is provided inside the mounting block 12. The triangular plate 13 is inserted into the slot 21, with the arc-shaped connecting surface 20 of the triangular plate 13 exposed outside the slot 21.

[0016] Furthermore, a fixing bolt 19 for tightening the connecting rod 11 is threaded onto the sleeve 18. The position of the connecting rod 11 can be adjusted by adjusting the tightness of the fixing bolt 19.

[0017] In this embodiment, an exhaust port 14 is provided on the dust cover 1, and the exhaust port 14 is connected to the air inlet of the industrial vacuum cleaner through a corrugated pipe 2. The industrial vacuum cleaner adopts an existing structure.

[0018] In this embodiment, a chip removal pipe is installed at the chip removal port 4, and a collection box 5 is placed below the chip removal pipe.

[0019] In this embodiment, a plurality of connecting screws are provided on the connecting end face of the cylindrical protective cover 3, and mounting holes corresponding to each connecting screw are provided on the dust cover 1. The connecting screws pass through the mounting holes and are fixed by nuts.

[0020] In practical use, the triangular plate 13 to be ground is inserted into the mounting block 12, with the arc-shaped connecting surface 20 on one side of the triangular plate 13 exposed outside the slot 21. The connecting rod 11 is pushed, and the triangular plate 13 enters the cylindrical protective cover 3 through the feed port 17. Grinding begins when the arc-shaped connecting surface 20 contacts the grinding brush 15. Light dust generated during grinding is sucked into an industrial vacuum cleaner, while heavier grinding debris is collected in the collection box 5 through the chip discharge port 4. After grinding, the triangular plate 13 is pulled out of the cylindrical protective cover 3 and removed from the mounting block 12. It is then flipped over and reinserted into the mounting block 12, at which point the arc-shaped connecting surface 20 on the other side of the triangular plate 13 is exposed outside the slot 21. The above operation is repeated for further grinding.

[0021] This invention uses a feeding mechanism to feed materials, allowing operators to stay away from the brushes and improving operational safety. Furthermore, the combination of the cylindrical protective cover 3 and the dust collection cover 1 reduces the scattering of grinding shavings during the grinding process. The dust generated during grinding can be handled by an industrial vacuum cleaner, and the metal grinding shavings are collected in the collection box 5 for recycling.
