Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for bridge housing processing, and in particular to a floating fixture for boring bridge housings. Background Technology

[0002] Automotive axle housings are typically machined into castings first, followed by a series of machining processes, such as boring. During machining, fixtures are often used to clamp the axle housing. Axle housings are usually large in size and weight, so the fixtures used are correspondingly large. These fixtures typically include a base, on which are often mounted brackets to support the rear and front of the axle housing. Pressure plates, which cooperate with the front and rear brackets, then lock the front and rear sections together. In actual clamping, the pressure plates and brackets are usually locked together with screws. Installation and disassembly are complex, increasing overall machining time and reducing efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a floating clamp for boring bridge housings, which solves the problem of low overall efficiency caused by the long disassembly and installation time required when clamping bridge housings in existing technologies.

[0004] According to an embodiment of this utility model, a bridge housing boring floating fixture includes a fixedly mounted base and a floating head located above the base. A sliding cylinder and a guide rod are vertically fixedly connected to the base. A telescopic rod that slides relative to the sliding cylinder is vertically fixedly connected to the floating head. The guide rod is also slidably mounted relative to the floating head, and a buffer spring located between the floating head and the base is also arranged around the guide rod. A pair of first telescopic push rods are installed on the floating head, and a second telescopic push rod is installed on the base. The second telescopic push rod and the two first telescopic push rods are arranged in an inverted isosceles triangle located between the sliding cylinder and the guide rod. Similar to existing technologies, the bridge housing is placed on a base. The difference lies in that this solution uses two first telescopic push rods on the floating head and a second push rod on the base to clamp the head of the bridge housing. During installation, simply place the bridge housing so that the head is between the floating head and the base, and the first and second telescopic push rods work together to clamp it. During disassembly, the first and second telescopic push rods simply return to their initial positions. The operation steps are simple and can shorten the operation time. Therefore, it solves the problem of low overall efficiency caused by the long disassembly and installation time required for clamping the bridge housing in existing technologies.

[0005] Furthermore, a third telescopic boom is installed on the floating head, located directly above the second telescopic boom, and the third telescopic boom is positioned higher than the two second telescopic booms.

[0006] Furthermore, the first telescopic rod, the second telescopic rod, and the third telescopic rod are all connected to hydraulic cylinders that drive their extension and retraction, and the hydraulic cylinders are fixed on the floating head or the base.

[0007] Furthermore, a recessed portion is provided on the base, and the hydraulic cylinder connected to the second telescopic top rod is installed in the recessed portion, with inclined support plates fixedly connected to both sides of the recessed portion.

[0008] Furthermore, the recessed part has symmetrical mounting slopes located on both sides of the second telescopic top rod, and the lower end of the mounting slope extends toward the bottom of the recessed part. The two inclined plates are respectively fixed to the two mounting slopes by screws.

[0009] Furthermore, a first mounting part and a second mounting part are respectively protruding and fixed on both sides of the base. The sliding cylinder is fixed on the first mounting part by a first screw, and the guide rod is fixed on the second mounting part by a second screw.

[0010] Furthermore, the telescopic rod is fixed to the float by a third screw, and the lower end of the telescopic rod slides against the inner wall of the sliding cylinder.

[0011] Furthermore, the floating head is also equipped with guide holes through which the guide rod slides.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The bridge housing is quickly clamped by the cooperation of two first telescopic push rods set on the floating head and a second telescopic push rod on the base. When disassembling, the first and second telescopic push rods can be returned to their initial positions. The operation steps are simple and can shorten the operation time. Therefore, it solves the problem that the existing technology requires a long time to disassemble and install when clamping the bridge housing, resulting in low overall efficiency.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] In an exemplary implementation, such as Figure 1 , 2As shown, this embodiment provides a floating fixture for boring axle housings, which includes a fixedly mounted base 1 and a floating head 2 located above the base 1. Similar to the prior art, a bracket 3 for supporting the tail of the axle housing 7 is provided on the base 1. The difference is that a recessed part 4 is provided on the base 1 below the floating head 2. The recessed part 4 has mounting ramps on both sides, with the lower end of the mounting ramps extending towards the bottom of the recessed part 4. An inclined support plate 6 is fixed to the mounting ramps by screws 5, which is used to support the head of the axle housing 7 on both sides below the ramps. The base 1 is vertically fixed with sliding cylinders 8 and guide rods 9 located on both sides of the sinking part 4. The floating head 2 is vertically fixed with a telescopic rod 10 that slides relative to the sliding cylinders 8. The floating head 2 is also provided with guide holes for the guide rod 9 to slide through. A buffer spring 11 is also arranged around the guide rod 9 between the floating head 2 and the base 1. The buffer spring 11 provides elastic support so that the floating head 2 can float up and down relative to the base 1 with the assistance of the guide rod 9, sliding cylinders 8 and telescopic rod 10. The floating head 2 is equipped with A pair of first telescopic push rods 12 and a second telescopic push rod 13 are installed on the base 1. The second telescopic push rod 13 and the two first telescopic push rods 12 are arranged in an inverted isosceles triangle between the sliding cylinder 8 and the guide rod 9. During installation, the bridge housing 7 is placed on the base 1 with its head directly below the floating head 2. Two inclined support plates 6 provide support to the head of the bridge housing 7 on both sides at the lower angle. The second telescopic push rod 13 pushes upward and the two first telescopic push rods 12 push downward, ultimately achieving a tight clamping of the head of the bridge housing 7. During disassembly, the first telescopic push rod 12 and the second telescopic push rod 13 return to their initial positions, making it easy to remove the bridge housing 7. The operation steps are simple and can shorten the operation time. Therefore, it solves the problem of low overall efficiency caused by the long disassembly and installation time required when clamping the bridge housing 7 in the prior art. During boring, the main machining surface is located on the end face of the head of the bridge housing 7. Therefore, in this solution, only the tail of the bridge housing 7 is lifted. By clamping the head of the bridge housing 7, boring can be performed.

[0021] like Figure 1As shown, in a more specific embodiment, a third telescopic rod 14 is also installed on the float 2, located between the two first telescopic rods 12 and directly above the second telescopic rods 13. The third telescopic rod 14 is positioned higher than the two second telescopic rods 13. The third telescopic rod 14 extends downwards, while the two first telescopic rods 12 extend towards the center of the bridge housing 7 head. Initially, due to the support provided by the buffer spring 11, there is a large height gap between the float 2 and the base 1 to accommodate the bridge housing 7 head (at the same time, there is also sufficient fixed width between the sliding cylinder 8 and the guide rod 9). After the bridge housing 7 head is in place, the first telescopic rods 12 and the second telescopic rods 13 are activated. The first telescopic rod 13 and the third telescopic rod 14 can contact the side of the head of the axle housing 7. Specifically, when the third telescopic rod 14 pushes down, it first contacts the top surface of the head of the axle housing 7 (the third telescopic rod 14 is located directly above the head of the axle housing 7), and then continues to push down, so that the entire floating head 2 can move upward relative to the base 1. This allows the entire floating head 2 to indirectly apply downward pressure to the head of the axle housing 7 through the third telescopic rod 14, thereby further making the clamping more stable. More specifically, the first telescopic rod 12, the second telescopic rod 13 and the third telescopic rod 14 are all connected to hydraulic cylinders 15 that drive their extension and retraction. The hydraulic cylinders 15 are fixed on the floating head 2 or the base 1.

[0022] In further proposals, such as Figure 1 As shown, the base 1 has a first mounting part 16 and a second mounting part 17 protruding and fixed on both sides respectively. The sliding cylinder 8 is fixed on the first mounting part 16 by the first screw 18, the guide rod 9 is fixed on the second mounting part 17 by the second screw 19, and the telescopic rod 10 is fixed on the floating head 2 by the third screw 20, with the lower end of the telescopic rod 10 slidingly engaging with the inner wall of the sliding cylinder 8. This not only realizes the installation of the sliding cylinder 8, the guide rod 9, and the telescopic rod 10, but also facilitates disassembly and subsequent maintenance.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
