Description

Technical Field

[0001] This utility model relates to the field of universal coupling processing, and in particular to a heat dissipation mechanism for drilling holes in universal coupling processing. Background Technology

[0002] Universal couplings, as components in mechanical transmission systems that enable variable-angle power transmission, typically include key parts such as shaft heads, cross shafts, and flanges. These parts require precise drilling for assembly and positioning. During drilling, the drill bit generates high-speed cutting friction with the workpiece metal, instantly producing a large amount of cutting heat. If this heat cannot be dissipated in time, it will severely affect processing quality and production efficiency.

[0003] A search of Chinese patents revealed publication number CN218504015U, entitled "Cooling Structure for Drilling Machines," belonging to the field of drilling machine cooling technology. This cooling structure includes a drilling machine body and a cooling assembly. In the above implementation, under the continuous action of a water pump, coolant inside the heat pipe enters the outlet pipe through a telescopic hose, causing the coolant to be sprayed from the nozzle. The sprayed coolant falls onto the drill bit, cooling it. The coolant on the drill bit eventually falls back into the water tank, where a filter filters it. The coolant that falls into the water tank is then drawn back into the heat pipe by the water pump and re-cooled. This allows for direct filtration, cooling, and recycling of used coolant, saving a significant amount of coolant during the use of the drilling machine body and reducing unnecessary waste.

[0004] Existing heat dissipation mechanisms lack splash protection. Generally, when cooling the drill bit, the heat dissipation mechanism uses a nozzle to spray water. The sprayed cooling water impacts the drill bit, causing splashing. This splashing carries debris with it, which not only contaminates the machine tool workbench and the ground but may also scald operators, posing a safety hazard. At the same time, the splashed waste liquid adheres to the equipment surface, accelerating corrosion. To solve the above problems, we propose a heat dissipation mechanism for drilling using universal couplings. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation mechanism for drilling holes in universal couplings, which has the advantage of preventing splashing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat dissipation mechanism for drilling in universal coupling processing, comprising a drilling machine lifting plate, two fixing plates bolted to the surface of the drilling machine lifting plate, a guide rod slidably sleeved on the inner wall of the fixing plate, a splash guard bolted to the bottom of the guide rod, a first spring provided between the fixing plate and the splash guard, and the first spring sleeved on the surface of the guide rod, a water baffle frame provided at the bottom of the splash guard, a sliding groove provided on the inner wall of the splash guard, a baffle slidably connected between the inner walls of the sliding groove, a snap-fit ​​rod slidably sleeved on the inner wall of the baffle, a second spring provided at one end of the snap-fit ​​rod, a toggle block bolted to the surface of the snap-fit ​​rod, a snap-fit ​​hole provided on the inner wall of the sliding groove, and one end of the snap-fit ​​rod snapping into the snap-fit ​​hole, a water supply mechanism provided at the bottom of the splash guard, and a filter mechanism provided inside the water supply mechanism.

[0007] By adopting the above technical solution, during drilling, the drilling machine's lifting plate lowers the drill bit and the fixed plate. When the fixed plate descends, the splash guard also descends. Before drilling, the splash guard presses against the top of the water-blocking frame, covering the drill bit. This achieves the purpose of preventing splashing, ensuring a clean working environment, preventing debris from injuring people, and improving safety. By moving the toggle block, the movement of the toggle block moves the locking rod, causing the locking rod to disengage from the locking hole. The baffle can then be removed, facilitating the replacement of the drill bit and the adjustment of the nozzle, thus improving practicality and ease of use.

[0008] The present invention is further configured such that: the water supply mechanism includes a water tank, the water tank is bolted to the bottom of the water baffle, a water pump is bolted to the inner wall of the water tank, the output end of the water pump is connected to a telescopic pipe, the other end of the telescopic pipe is connected to a universal nozzle, and the universal nozzle is fixedly sleeved to the inner wall of the splash guard.

[0009] By adopting the above technical solution and setting up a water supply mechanism, cooling can be facilitated.

[0010] The present invention is further configured such that: the filtration mechanism includes a partition plate, the partition plate is bolted to the inner wall of the water tank, a filter screen is slidably connected between the inner walls of the water tank, a cover plate is provided on the surface of the water tank, the cover plate is threadedly connected to the inner wall of the water tank with fixing bolts, and a water inlet hole is provided on the top of the water tank.

[0011] By adopting the above technical solution, cooling water enters the water tank through the inlet hole by setting up a filtration mechanism. The baffle in the water tank prevents water from settling. After settling, the cooling water flows out from the top of the baffle, is filtered by the filter screen, and is reused, thus enabling water recycling and reducing costs.

[0012] The present invention is further provided with a glass observation window on the top of the splash shield.

[0013] By adopting the above technical solution and setting a glass observation window, it is convenient to observe the drilling process.

[0014] The present invention is further configured such that the surface of the actuating block is provided with anti-slip texture.

[0015] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0016] The present invention is further configured such that: the bottom of the drilling machine lifting plate is bolted to a support plate, and the support plate is fixedly sleeved with the surface of the telescopic tube.

[0017] By adopting the above technical solution, the telescopic pipe is fixed by setting a support plate to ensure stability.

[0018] The present invention is further provided with a sealing gasket between the cover plate and the inner wall of the water tank.

[0019] By adopting the above technical solution, water leakage is prevented by setting a sealing gasket.

[0020] The present invention is further configured such that a valve is connected to the surface of the water tank.

[0021] By adopting the above technical solution and installing valves, drainage can be facilitated.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model achieves the purpose of preventing splashing by having the drilling machine's lifting plate lower the drill bit and fixing plate during drilling, and the splash guard lowers when the fixing plate lowers. Before drilling, the splash guard presses against the top of the water-blocking frame to cover the drill bit, thus ensuring a clean working environment, preventing debris from injuring people, and improving safety. 2. This utility model uses a movable toggle block, which moves the locking rod to disengage it from the locking hole, allowing the baffle to be removed. This facilitates drill bit replacement and nozzle adjustment, improving practicality and ease of use. Attached Figure Description
