Description

Technical Field

[0001] This utility model relates to the field of casting hole positioning technology, and in particular to a metal casting hole positioning device. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by grinding and other subsequent means to obtain an object with a certain shape, size and performance. Casting opening refers to the process of making holes in the casting during or after casting. There are many types of openings, including bolt holes, weight reduction holes, observation holes, oil holes, air passages and process holes.

[0003] An existing metal casting hole-opening positioning device (publication number: CN221871117U) uses two sets of positioning clamps to elastically clamp the metal casting. However, when dealing with large-volume metal castings, it can only position the two sides of the metal casting and cannot effectively clamp other parts of the metal casting. This will affect the stability of the metal casting hole-opening process, and will also generate debris and waste during the hole-opening process, which is not convenient for workers to clean and collect. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal casting hole positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal casting hole-opening positioning device includes a base with a placement groove. A scrap box is disposed inside the placement groove and embedded in the inner wall of the placement groove. A support plate is installed at the upper end of the scrap box. A strong magnetic rod is installed inside the scrap box by fasteners. A cylinder is fixedly installed at the upper end of one side of the base. A connecting plate is fixedly disposed on the output shaft of the cylinder. A hydraulic rod is fixedly disposed at one end of the connecting plate. An extension plate is fixedly disposed on the output shaft of the hydraulic rod. A side block is movably disposed inside the extension plate.

[0007] As a further embodiment of this utility model, the side wall of the support plate is fixedly provided with a buckle, the upper end of the waste box is provided with a slot, and the support plate is provided with a through groove.

[0008] As a further embodiment of this utility model, the buckle is fitted into the slot, and a positioning pressure plate is fixedly provided on the side of the connecting plate away from the cylinder.

[0009] As a further embodiment of this utility model, a spring is provided on the inner wall of the extension plate, and a rubber pad is fixedly provided on the positioning pressure plate.

[0010] As a further embodiment of this utility model, the positioning pressure plates are symmetrically distributed on the base, and the two ends of the spring are respectively fixedly connected to the side block and the inner wall of the extension plate.

[0011] As a further embodiment of this utility model, the strong magnetic rods are distributed at equal intervals in the waste box, and the extension plates are symmetrically distributed on the connecting plate.

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

[0013] When a metal casting needs to be drilled, the operator first places the casting on top of the support plate. Then, two sets of cylinders are activated simultaneously, pushing two sets of positioning plates closer to the casting. The two positioning plates clamp the casting's two sides, while four springs position the other two sides. As needed, a hydraulic rod can be activated to move an extension plate, adjusting the side blocks to ensure precise positioning. During the drilling process, multiple strong magnetic rods attract and collect debris from the casting, preventing it from scattering and facilitating subsequent processing. After removing the drilled casting, the operator simply pulls the clips upwards to separate the support plate from the waste box, allowing for the disposal of collected debris and improving processing convenience.

The two sets of positioning plates 101 first position the two sides of the metal casting, and at the same time, with the cooperation of the four sets of springs 203, the four sets of side blocks 301 position and clamp the other two sides of the metal casting. As needed, the hydraulic rod 105 can be started to push the extension plate 1. 06 is moved so that the extension plate 106 drives the side block 301 to adjust its position, so that the side block 301 can accurately position the metal casting. During the opening process of the metal casting, multiple sets of strong magnetic rods 202 are used to attract the debris generated by the metal casting and collect the debris inside the waste box 201 to prevent the debris from flying around. The worker only needs to pull the buckle 303 upward to separate the support plate 3 from the waste box 201, so as to process the debris and waste material collected in the waste box 201.

[0024] In this embodiment, a buckle 303 is fixedly provided on the side wall of the support plate 3, a slot 302 is provided at the upper end of the waste box 201, and a through slot 4 is provided on the support plate 3.

[0025] When in use, when the positioning plate 101 is close to the metal casting, it simultaneously drives the two sets of side blocks 301 to be close to other parts of the metal casting, thereby clamping and positioning multiple surfaces of the metal casting.

[0026] In this embodiment, the buckle 303 is fitted into the connecting groove 302, and a positioning pressure plate 101 is fixedly provided on the side of the connecting plate 102 away from the cylinder 103.

[0027] In use, the support plate 3 is placed on the waste box 201 by pushing the buckle 303 to engage with the slot 302, so as to facilitate disassembly and assembly. The through slots 4 are evenly distributed on the support plate 3, and the waste box 201 at the bottom can collect debris through the through slots 4.

[0028] In this embodiment, a spring 203 is provided on the inner wall of the extension plate 106, and a rubber pad 104 is fixedly provided on the positioning pressure plate 101.

[0029] In use, two sets of positioning pressure plates 101 are provided on the base 1, and rubber pads 104 are provided on both sets of positioning pressure plates 101.

[0033] In use, multiple sets of strong magnetic rods 202 are provided in the waste box 201. When metal castings generate metal shavings during the drilling process, multiple sets of strong magnetic rods 202 are used to adsorb the iron filings and waste, thereby ensuring the cleanliness and safety of the work surface and providing convenience for the staff.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When a metal casting needs to be drilled, the operator can first place the metal casting on the upper end of the support plate 3, and then simultaneously start two sets of cylinders 103, so that the two sets of cylinders 103 push the two sets of positioning plates 101 close to the metal casting. First, the two sets of positioning plates 101 position and clamp the two sides of the metal casting. At the same time, with the cooperation of four sets of springs 203, the two sets of side blocks 301 position the other two sides of the metal casting. As needed, the hydraulic rod 105 can be started to push the extension plate 10. 6. Move the extension plate 106 to adjust the position of the side block 301, so that the side block 301 can accurately position the metal casting. During the drilling process of the metal casting, multiple sets of strong magnetic rods 202 are used to attract the debris generated by the metal casting, so that the debris is collected in the inside of the waste box 201, preventing the debris from flying around, so that the staff can handle it uniformly. After the metal casting with the hole is removed, the staff only needs to pull the buckle 303 upward to separate the support plate 3 from the waste box 201, so as to process the debris and waste material collected in the waste box 201, thereby improving the convenience of processing and use.
