Description

Technical Field

[0001] The present application relates to the technical field of drilling equipment, and in particular to a hole-making device for stainless steel metal castings. Background Art

[0002] In the field of industrial manufacturing, metal casting processing is a crucial process link. With the continuous development of the manufacturing industry, the requirements for the processing accuracy and efficiency of metal castings are becoming higher and higher. Especially in the production process of stainless steel metal castings, the hole opening operation is one of the common and critical processes. Its quality directly affects the subsequent performance of the casting and the overall quality of the product.

[0003] For the drilling operation of stainless steel metal castings, the common practice is to manually use handheld drilling tools. Workers need to rely on experience to control the position and depth of the drilling, and manually apply pressure to push the drill bit forward. In addition, a simple fixing fixture is used to fix the casting on the workbench, and then an ordinary bench drill is used to drill the hole. Another way is to use semi-automatic drilling equipment. These devices usually have certain positioning functions, but still require more manual intervention to adjust the drilling parameters.

[0004] Regarding the above-mentioned related technologies, these existing hole-opening methods have obvious defects. The accuracy of the manual handheld drilling tool method depends entirely on the worker's experience and skill level. It is difficult to ensure consistent hole-opening accuracy for each casting. Moreover, long-term operation can easily cause worker fatigue, further affecting the processing quality. Although simple fixing fixtures and ordinary bench drills can achieve a certain degree of fixation, the casting is prone to shaking during the drilling process, resulting in deviation of the drilling position. Summary of the Invention

[0007] By adopting the above technical solution, when it is necessary to drill a hole in a metal casting, first, the metal casting is fixed by the clamping part, then the telescopic connecting part is started to connect the adjusting part with the lifting plate, then the lifting cylinder and the rotating motor are started, and the drill bit can drill a hole in the metal casting. During the drilling process, the telescopic connecting part is shortened, and the lifting plate and the clamping plate are connected by the telescopic connecting part and the two adjusting parts, so that the drill bit can drill the hole stably; the support plate of the support assembly provides an installation base for other components; the clamping part of the clamping assembly can firmly clamp the metal casting to ensure the stability of the casting during processing; the drilling frame, lifting cylinder, lifting plate, rotating motor and drill bit of the drilling assembly work together to accurately drill a hole in the metal casting; the adjusting part and the telescopic connecting part of the positioning assembly cooperate, and the elastic area composed of the arc plate and the adjusting spring of the adjusting part can change with the movement of the clamping part. The telescopic connecting part can push the upper adjusting part to connect or separate with the lifting plate, ensuring the accurate installation and positioning of the workpiece, which is beneficial to the problem of drilling position offset and improving the drilling accuracy.

[0008] In a specific possible implementation scheme, the positioning assembly also includes a measuring part, which includes a scale rod and a metering rod.

According to the depth of the hole to be drilled, the operator observes the abutment between the end of the metering rod away from the arc plate and the scale rod, which facilitates a clear understanding of the depth of the hole and can provide real-time feedback on the drilling depth information, thereby facilitating the operator to accurately understand the drilling depth according to the scale, thereby stopping the drilling operation in time and improving the drilling accuracy.

[0012] In a specific embodiment, a feed opening is provided on the top of the support plate, and the feed opening penetrates the support plate along the thickness direction of the support plate; The cam is connected to the support plate, and the driving mechanism is connected with the.

[0013] By adopting the above technical solution, the support plate is provided with a discharge port to allow waste to fall; the driving frame of the driving part can place the metal casting, and the driving motor drives the screw to rotate through the coupling. Since the two adjacent bevel gears are engaged with each other, multiple screws can rotate synchronously, and then the clamping part threadedly connected to the screw can slide along the length direction of the screw, realizing automatic, synchronous and stable clamping of the metal casting, ensuring the stability of the metal casting during the processing, and avoiding the deviation of the drilling position due to shaking.

[0016] In a specific embodiment, the two flip plates are each connected to an anti-slip pad on one side close to each other.

[0017] By adopting the above technical solution, when the two flip plates clamp the metal casting, the anti-slip pad contacts the metal casting, which can enhance the stability of the flip plates clamping the metal casting.

The elastic area composed of the arc plate of the adjusting part and the adjusting spring can change with the movement of the clamping part. The telescopic connecting part can push the upper adjusting part to connect or separate with the lifting plate, ensuring the accurate installation and positioning of the workpiece, which is beneficial to solving the problem of drilling position offset and improving the hole-opening accuracy.

[0027] The designed hole-opening device for stainless steel metal castings, the scale rod and the metering rod in the metering part cooperate to provide real-time feedback of drilling depth information, making it convenient for the operator to accurately understand the drilling depth according to the scale, thereby stopping the drilling operation in time and improving the hole-opening accuracy.

[0028] The specially designed hole-drilling device for stainless steel metal castings enables a water pump to pump coolant from the cooling box to the nozzle through the cooling pipe. When the drill is drilling a hole, the nozzle sprays water onto the contact point between the drill bit and the metal casting, effectively reducing the drill bit temperature and preventing workpiece deformation. It can also flush and remove metal waste, avoid blockage, and keep the processing area clean. BRIEF DESCRIPTION OF THE DRAWINGS
