Description

Technical Field

[0001] This utility model belongs to the field of positioning and clamping, and specifically relates to a positioning and clamping device for a gantry milling machine. Background Technology

[0002] Casting is suitable for producing workpieces with complex shapes and high requirements for surface and dimensional accuracy. The process is complex and has many uncontrollable factors. Precision casting has a wide range of applications in industries such as aviation, aerospace, weaponry, electronics, and shipbuilding. With the continuous development of casting technology, the technical requirements for cast workpieces are also becoming increasingly higher. The casting process is divided into multiple stages, including melting, shell and core processing, molding and casting, post-processing, and outsourced processing. As one of the main equipment for processing large castings, the gantry milling machine hoists the castings onto the gantry milling machine's worktable via an overhead crane. The castings are then manually straightened, using forklifts to push or personnel to strike them with copper rods, resulting in very low straightening efficiency and difficulty in controlling the deviation of the straightening reference, leading to a very long straightening time. Although the castings can be pre-positioned and straightened using a tripod, the castings are prone to impact damage to the tripod during hoisting, and the loss of accuracy after the tripod impact is very common, making it difficult to guarantee the effectiveness of the tripod as a reference for positioning.

It has a simple structure and is convenient and practical. The square telescopic column is driven by a power motor to extend and retract, so that the pad plate presses against the casting to level the casting and achieve the effect of rapid leveling of the casting.

Detailed Implementation

[0017] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figures 1 to 2As shown; a positioning and clamping device for a gantry milling machine includes an angle control seat 1 and a positioning and clamping device 2, the positioning and clamping device 2 being connected to the angle control seat 1; the positioning and clamping device 2 includes a power motor 21, a machine housing 22, a positioning clamp 26, and a power gear 27, the machine housing 22 having a machine chamber 23 and an adjustment chamber 24, the power motor 21 being mounted on the angle control seat 1 with its power rod passing through the side wall of the machine housing 22 and connected to the power gear 27, the power gear 27 being disposed within the machine chamber 23 and connected to the positioning clamp 26. 6. Transmission connection: Several positioning clamps 26 extend from one end through the machine housing 22 and the adjustment chamber 24 into the machine chamber 23. Each positioning clamp 26 includes a driven gear 28, a lead screw 29, a square telescopic column 210, a screw 211, a hanging ring 212, a nut 213, and a C-shaped hanging plate. One end of the square telescopic column 210 is connected to the screw 211, and the other end extends through the side wall of the machine housing 22 into the adjustment chamber 24. One end of the square telescopic column 210 is provided with a lead screw hole that cooperates with the lead screw 29 for transmission. One end of the lead screw 29 is provided with a lead screw hole. The screw 211 has a hole and extends through the adjustment chamber 24 to the mechanical chamber 23, where it connects to the driven gear 28. The driven gear 28 meshes with the power gear 27. The hanging ring 212 is fitted onto the screw 211, and the nut 213 is connected to the screw 211. The hanging ring 212 has several hook holes 214 on its side. One end of the C-shaped hanging plate is connected to a connecting post that inserts into the hook holes 214. An optical scale 25 is installed inside the adjustment chamber 24, and the measuring end of the optical scale 25 is connected to a square telescopic post 210. One end of the screw 211 is connected to a pad. Plate 215; the hanging ring 212 is square; the angle control seat 1 includes a side support plate 11, a bottom 13, a rotating shaft 14, a rotating plate 15, and a rotating frame 16. The two side support plates 11 are connected to the bottom 13, the rotating plate 15 is connected to the rotating frame 16, and the two sides of the rotating frame 16 are respectively connected to the corresponding side support plates 11 through the rotating shaft 14. The rotating plate 15 is connected with bolts. The top and side of the side support plate 11 are provided with fixing screw holes 17, and the bottom 13 is provided with several fixing holes. The bottom of the bottom 13 is provided with a limit plate 12.

[0020] When locating a parallel reference for a casting, it is generally done after the casting is hoisted onto the worktable of a gantry milling machine. However, castings that are generally wider at the top and narrower at the bottom are difficult to place stably and require support. By rotating the positioning and clamping device 2, the rotating frame 16 rotates around the axis 14, so that the rotating plate 15 makes stable contact with the top or side of the side support plate 11, making the rotating plate 15 vertical or horizontal. Then, the rotating plate 15 is fixed to the top or side of the side support plate 11 with screws. The fixing screw hole 17 is used to connect the bolts for fixing the rotating plate 15. When the positioning and clamping device 2 is working, the power motor 21 drives the power gear 27 to rotate, which in turn drives the driven gear 28 to rotate. The driven gear 28 drives the lead screw 29 to rotate, and the rotation of the lead screw 29 causes the square telescopic column 210 to extend and retract. The lead screw 29 and the lead screw hole cooperate to complete the extension and retraction of the square telescopic column 210. The action involves the square telescopic column 210 driving the screw 211 and the pad 215 to move, causing the pad 215 to push the casting placed on the gantry milling machine table. At least two positioning clamping devices 2 cooperate to push both ends of the casting, achieving the purpose of quickly leveling and supporting the casting. Then, one end of the C-shaped hanging plate hooks the casting, and the other end is inserted into the hook hole 214 through the connecting column. By rotating the nut 213, the nut 213 pushes the hanging ring 212 to move, and the hanging ring 212 drives the C-shaped hanging plate. The other end of the C-shaped hanging plate hooks the casting tightly onto the pad 215, achieving the purpose of fixing the casting and preventing the casting from shifting due to vibration during cutting. The limiting clamping table 12 is used to clamp in the T-slot of the gantry milling machine table to avoid the phenomenon that the bolts are difficult to fix the angle control seat 1 when the positioning clamping device 2 pushes the casting, which would cause the angle control seat 1 to shift.
