Description

Technical Field

[0001] This invention relates to the technical field of casting processing, specifically to a drilling device for casting processing. Background Technology

[0002] Castings are widely used in machinery, automotive, and aerospace industries, such as engine blocks, pump bodies, and valve bodies. These components typically require the machining of multiple holes of different sizes to achieve functions such as assembly, oil passages, and air passages. Unlike regular workpieces such as sheet metal and profiles, the machining process for castings has significant unique characteristics, necessitating specialized drilling equipment. Castings are formed by casting in molds, and the surface of the blank may contain flash, gating remnants, and significant dimensional deviations, making it impossible to directly adapt to the standardized positioning of general-purpose drilling equipment. Most castings are made of cast iron or cast steel, with hardness reaching HB180-300, and some high-strength castings even higher. At the same time, internal defects such as sand holes, slag inclusions, and shrinkage cavities may exist, which can easily lead to tool wear or breakage during machining. For some critical holes, the equipment needs to be compatible with switching between different precision requirements. Therefore, we need drilling equipment for casting machining.

[0003] The current drilling equipment for casting processing has several limitations. It cannot clamp and fix castings of different sizes and shapes during operation, cannot provide precise guidance for drilling positions, cannot change or adjust the drilling tools, cannot adjust the drilling diameter for different sizes and progresses, cannot collect and uniformly process the debris generated during drilling, and cannot quickly and efficiently remove the castings after drilling. Summary of the Invention

[0004] The purpose of this invention is to provide a drilling apparatus for machining castings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A drilling device for machining castings includes a worktable with slide rails at both ends. A first hydraulic cylinder is mounted at one end of the worktable, and a movable stage is mounted at one end of each slide rail. A buckle is mounted at one end of the movable stage, and a support platform is mounted on the upper part of the movable stage. A sliding groove is formed in the middle of the support platform, and a second hydraulic cylinder is mounted at one end of the support platform. A fixing ring is mounted at one end of the second hydraulic cylinder, and a drive motor is installed inside the fixing ring. A connector is mounted at one end of the drive motor, and a drill bit is mounted at one end of the connector. A laser is mounted on the front end of the movable stage, which is mounted on the upper part of the support platform. The aiming device has a placement slot at the upper end of the worktable, inside which a third hydraulic cylinder is installed. A lifting plate is installed on the upper end of the third hydraulic cylinder. An operating table is installed at the upper end of the worktable, with clamping plates installed at both the front and rear ends of the operating table. Screws are installed at both ends of the clamping plates. A push rod is installed at one end of the operating table, with a scraper installed at one end of the push rod. A limit groove is opened at the front end of the worktable, with a storage box installed at the upper end of the limit groove. An air pump is installed at one end of the storage box, and a connecting pipe is installed at the upper end of the storage box. An air inlet frame is installed at one end of the connecting pipe, and a filter screen is installed at the front end of the air inlet frame.

[0006] Preferably, the movable table forms a sliding structure with the worktable via a slide rail, and the movable table is engaged with the first hydraulic cylinder via a snap-fit.

[0007] Preferably, the drill bit is threadedly connected to the connector, and the drill bit forms a rotating structure with the support platform via a drive motor.

[0008] Preferably, the drive motor forms a sliding structure with the support platform through a slide groove, and the drive motor is movably connected to the support platform through a second hydraulic cylinder.

[0009] Preferably, the lifting plate forms a lifting structure with the worktable via a third hydraulic cylinder, and the lifting plate is in close contact with the worktable.

[0010] Preferably, the clamping plate is movably connected to the operating table via a screw, and the scraper forms a telescopic structure with the operating table via a push rod.

[0011] Preferably, the air intake frame is threadedly connected to the connecting pipe, and the air intake frame is snapped into place with the filter screen.

[0012] The method for using a drilling device for machining castings includes the following steps: S1. Turn on the power to the device, place the casting to be drilled on the top of the operating table, and fix the clamping plate by tightening the screws at both ends to secure the casting. S2. The laser aiming device on the upper part of the support platform in the device points out the position for drilling holes in the casting. The first hydraulic cylinder moves the sliding rails at both ends of the movable table back and forth. The drilling operation of the casting is carried out when the table is moved to the appropriate position. S3. The drill bit used for drilling the casting can be adjusted left and right by the second hydraulic cylinder, and the support table can be adjusted in height on the movable table, so as to drill holes in different positions of the casting. S4. Next, open and operate the air intake frame connected to the air pump. The operation of the air pump can absorb the debris generated by drilling and suck the debris into the storage box through the connecting pipe for collection. S5. Finally, remove the casting after drilling, loosen the clamping plate, and then lift the connected lifting plate upward by operating the third hydraulic cylinder. After lifting, quickly remove the casting after drilling.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The movable platform is moved by the first hydraulic cylinder to move the upper support platform. At the same time, the second hydraulic cylinder can adjust the height and lateral position of the drilling hole on the support platform through the slide groove. The drilling operation is performed on the casting by the drive motor. Different sizes of drill bits can be changed according to the required drilling diameter. The storage box in the device can collect the debris generated by drilling through the operation of the air pump, keeping the drilling environment clean.

[0014] 2. The third hydraulic cylinder installed below the lifting plate moves upwards, which can quickly lift and remove the casting after drilling. The device can fix castings of different sizes and dimensions through the flexible movement of the clamping plate, maintaining stability during drilling. The installed laser aiming device can accurately guide the drilling position of the casting, maintaining the accuracy of the drilling position. Attached Figure Description
