Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a blade drilling device. Background Technology

[0002] In the machining industry, cutting inserts are key components of cutting tools, and their machining accuracy directly affects the workpiece's machining quality and the tool's lifespan. Traditional drilling equipment typically suffers from the following technical problems when drilling with cutting inserts.

[0003] Existing cutting tool drilling devices often use simple bolt clamping or manual clamping methods for their clamping components. During the drilling process, problems such as cutting tool loosening can easily lead to drilling position deviation and large hole diameter errors. During the cutting tool drilling process, a large amount of cutting heat and metal chips are generated. The cooling systems of existing devices are mostly simple spray cooling, which cannot accurately cover the drilling area with coolant, resulting in poor cooling effect. At the same time, the accumulation of chips can easily clog the drill hole, affecting the machining accuracy. Furthermore, there is a lack of effective coolant recovery and filtration devices, resulting in resource waste and environmental pollution.

[0004] To address this issue, we provide a blade drilling device that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a blade drilling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a blade drilling device, comprising a base, wherein a hole-opening mechanism is provided at the top of the base and a support leg is provided at the bottom of the base;

[0007] The hole-opening mechanism includes a clamping assembly disposed at the top of the base, a drilling assembly disposed directly above the clamping assembly, and a cleaning and cooling assembly disposed at the top of the drilling assembly.

[0008] Preferably, the clamping assembly includes a slide groove formed at the top of the base, a slider slidably connected to the inner side of the slide groove via a slot, a clamping block provided on the inner side of the slider, a first threaded rod longitudinally passing through both ends of the inner side of the slider and the clamping block, a clamping valve being clamped at the top end of the first threaded rod, a second threaded rod passing through both ends of the slider, a servo motor being connected to one end of the second threaded rod with a flat key, and a fixing block being connected to the other end of the second threaded rod.

[0009] Preferably, the drilling assembly includes a gantry frame fixedly installed on the outside of the base, a hydraulic rod fixedly installed on the bottom inner side of the gantry frame, and a drill bit fixedly installed on the bottom end of the hydraulic rod.

[0010] Preferably, the cleaning and cooling assembly includes a water tank fixedly installed at the top of the gantry frame, a water guide pipe provided on the outside of the water tank, a nozzle fixedly installed at the other end of the water guide pipe, a strainer plate provided directly below the gantry frame, a conduit plate provided at the bottom end of the strainer plate, a collection box connected to the other end of the conduit plate, a filter screen provided on the inside of the collection box, a water pump provided on the outside of the collection box, and a return pipe provided on one side of the water pump.

[0011] Preferably, the clamping components are arranged symmetrically.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the design of the clamping assembly and the sliding connection structure of the slide groove and slider, combined with the second threaded rod, can clamp the blade according to its shape, avoiding blade loosening due to insufficient clamping force, while also preventing blade deformation due to excessive tightness. The clamping valve, in conjunction with the first threaded rod, drives the clamping block 213 to clamp the blade thickness, further improving the clamping tightness. Drilling is performed using a gantry frame and hydraulic rod, allowing precise adjustment of the drill bit's feed speed and downward pressure via the hydraulic system. This avoids the low drilling efficiency problem caused by the unadjustable parameters of traditional fixed-speed motors. The clean cooling system allows for precise spraying of coolant into the drilling area, significantly improving cooling efficiency compared to traditional spray cooling. This rapidly reduces drilling temperature, protects the cutting edge performance of the cutting tool, reduces drill wear caused by high temperatures, and extends tool life. The inclusion of a strainer, guide tube, and collection box ensures timely collection of metal debris generated during drilling, preventing debris buildup and blockage. The circulation system within the collection box, consisting of a filter, water pump, and return pipe, filters, recycles, and reuses the coolant, reducing waste and environmental pollution, aligning with green manufacturing principles.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 As shown, the blade drilling device of this embodiment includes a base 1, an opening mechanism 2 is provided at the top of the base 1, a support leg 3 is provided at the bottom of the base 1, the opening mechanism 2 includes a clamping component 21 provided at the top of the base 1, a drilling component 22 is provided directly above the clamping component 21, and a cleaning and cooling component 23 is provided at the top of the drilling component 22.

[0021] Furthermore, the clamping assembly 21 includes a slide groove 211 formed at the top of the base 1. A slider 212 is slidably connected to the inner side of the slide groove 211 via a slot. A clamping block 213 is provided on the inner side of the slider 212. A first threaded rod 214 is longitudinally inserted through both ends of the inner sides of the slider 212 and the clamping block 213. A clamping valve 215 is engaged at the top end of the first threaded rod 214. A second threaded rod 216 is inserted through both ends of the slider 212. A servo motor 217 is connected to one end of the second threaded rod 216 with a flat key. A fixing block 218 is connected to the other end of the second threaded rod 216. By sliding the slider 212 in the slide groove 211 and cooperating with the servo motor 217 to drive the second threaded rod 216 to move and clamp, the clamping position can be flexibly adjusted according to the blade size, solving the problem of poor adaptability of traditional fixed clamping structures to blades of different specifications. The clamping valve 215, in conjunction with the first threaded rod 214, adjusts the clamping of the clamping block 213 on the blade thickness, avoiding drilling deviation due to insufficient clamping force.

[0022] Furthermore, the drilling assembly 22 includes a gantry 221 fixedly installed on the outside of the base 1. A hydraulic rod 222 is fixedly installed on the bottom inner side of the gantry 221, and a drill bit 223 is fixedly installed on the bottom end of the hydraulic rod 222. The gantry 221 provides a stable support structure for the hydraulic rod 222 and the drill bit 223. The drill bit 223 is driven by the hydraulic rod 222 to drill the cutting tool. The feed speed and downward pressure of the drill bit 223 can be adjusted in real time, avoiding excessive wear of the drill bit 223 caused by the constant speed drive of the traditional motor, thereby extending the service life of the drill bit 223.

[0023] Furthermore, the cleaning and cooling assembly 23 includes a water tank 231 fixedly installed at the top of the gantry 221. A water guide pipe 232 is provided on the outside of the water tank 231, and a nozzle 233 is fixedly installed at the other end of the water guide pipe 232. A strainer 234 is provided directly below the gantry 221, and a conduit 235 is provided at the bottom end of the strainer 234. The other end of the conduit 235 is connected to a collection box 236. A filter screen 237 is provided on the inside of the collection box 236, and a water pump 238 is provided on the outside of the collection box 236. A return pipe 239 is provided on one side of the water pump 238. Through the arrangement of the water tank 231, the following can be achieved: The coolant is precisely guided into the nozzle 233 through the water guide pipe 232. At the same time, the coolant can be precisely sprayed into the drilling area through the nozzle 233. The filter plate 234 allows debris and coolant to pass through and enter the collection tank 236 after passing through the guide pipe 235. After the metal debris is filtered by the filter screen 237, the coolant enters the collection tank 236 at the bottom. Then, the water pump 238 guides the coolant into the water tank 231 through the return pipe 239, completing the circulation of coolant. Compared with the traditional one-time cooling method, the coolant consumption is reduced.

[0024] Furthermore, the clamping components 21 are symmetrically arranged, which can improve the clamping effect of the clamping components 21.

[0025] Working Principle: During equipment operation, the cutting tool to be drilled is first placed on the top of the perforation plate 234. The servo motor 217 is started, driving the second threaded rod 216 to rotate via a key, causing the slider 212 to slide along the groove 211, initially positioning and clamping the cutting tool. Subsequently, the rotating clamping valve 215 drives the first threaded rod 214 to move axially, causing the clamping block 213 to adaptively adjust the clamping force, achieving precise clamping in the thickness direction of the cutting tool. After clamping, the hydraulic rod 222 drives the drill bit 223 to feed vertically downwards, performing drilling operations on the cutting tool. Simultaneously, the coolant in the water tank 231 is transported to the nozzle 233 via the water pipe 232, spraying it onto the contact area between the drill bit 223 and the cutting tool, achieving real-time cooling and lubrication. The coolant carrying iron filings passes through the sieve holes of the perforation plate 234, flows along the guide tube 235 into the collection tank 236, is filtered by the filter screen 237, and stored in the tank. Water pump 238 starts synchronously, pumping the filtered coolant to water tank 231 through return pipe 239, forming a closed-loop cooling system. This completes the use of a blade drilling device.
