Description

Technical Field

[0001] This utility model relates to the field of CNC cutting tool technology, specifically a cutting tool with a cooling function. Background Technology

[0002] CNC cutting tools are tools used for cutting processes in mechanical manufacturing, also known as cutting tools. In a broad sense, cutting tools include both cutting tools and grinding wheels; furthermore, "CNC cutting tools" include not only cutting inserts but also accessory tools such as tool holders and tool shanks. Cutting tools can be classified into five categories based on the form of the workpiece's machined surface: Tools for machining various external surfaces, including turning tools, planing tools, milling cutters, external surface broaches, and files; hole machining tools, including drills, reamers, boring tools, and internal surface broaches; thread machining tools, including taps, dies, automatic thread cutters, thread turning tools, and thread milling cutters; gear machining tools, including hobs, gear shapers, gear shaving cutters, and bevel gear machining tools; and parting tools, including toothed circular saw blades, band saws, hacksaws, parting turning tools, and saw blade milling cutters. In addition, there are combination tools. Based on the cutting motion and corresponding cutting edge shape, cutting tools can also be divided into three categories. General-purpose cutting tools include turning tools, planing tools, milling cutters (excluding form turning tools, form planing tools, and form milling cutters), boring tools, drills, reamers, and saws; form tools, whose cutting edges have the same or nearly the same shape as the cross-section of the workpiece being machined, such as form turning tools, form planing tools, form milling cutters, broaches, conical reamers, and various threading tools; generating tools are used to machine the tooth surfaces of gears or similar workpieces using the generating method, such as hobs, gear shapers, gear shaving cutters, bevel gear planers, and bevel gear milling cutter discs. All cutting tools consist of a clamping part and a working part. For integral structure cutting tools, both the clamping part and the working part are made on the tool body; for insert-type cutting tools, the working part (tooth or insert) is inlaid on the tool body. The clamping part of a cutting tool can be either with a hole or with a shank. Cutting tools with a hole rely on the inner hole to be fitted onto the spindle or mandrel of the machine tool, and torsional torque is transmitted by an axial key or end face key, such as cylindrical milling cutters and sleeve face milling cutters.

[0003] Taking an internally cooled cutting tool with high-efficiency cooling function (CN209867392U) as an example, this utility model provides an internally cooled cutting tool with high-efficiency cooling function, including a tool holder, a tool head, an insert, a tool pad, and a pressure plate mechanism. The tool head is installed at the front end of the tool holder, and heat dissipation columns are evenly distributed in the liquid storage tank located at the bottom of the insert. This utility model diverts the coolant entering the liquid storage tank through the liquid storage tank with heat dissipation columns, changing the flow state of the coolant in the liquid storage chamber, greatly increasing the effective contact area between the coolant and the internal area of ​​the insert, enhancing heat exchange, thereby improving the overall heat exchange efficiency of the insert and reducing the cutting temperature of the insert. At the same time, the coolant in the liquid storage tank can be atomized and sprayed out through the outlet hole, which greatly promotes the evaporation of the coolant, further removing a large amount of cutting heat, helping to reduce tool wear and extend tool life.

[0004] but:

[0005] It dissipates heat solely through water cooling and cannot quickly switch between tools as needed. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a cutting tool with a cooling function.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a cutting tool with a cooling function, including a handle, and a cutting tool mechanism is provided above the handle; the cutting tool mechanism includes: a rotating tool holder, the rotating tool holder being rotatably connected to the handle via a rotating shaft, a water inlet groove being provided above the rotating tool holder, a pipe interface being provided above the water inlet groove, the pipe interface being fixedly connected to the top of the rotating tool holder, a tool pad and a cutting head being fixedly installed on the left and right sides of the rotating tool holder via fixing pins, a water baffle being fixedly connected below the cutting head, and a fixing seat being fixedly connected to the front and back of the rotating tool holder.

[0010] Preferably, the front of the tool holder is provided with a fixing mechanism; the fixing mechanism includes: a sleeve, which is fixedly connected to the front of the tool holder; a fixing strip is elastically connected to the inner surface of the sleeve by a spring; a through hole is opened in the middle of the fixing strip; the fixing strip is inserted into a fixing seat through an insertion hole; an opening is opened on the right side of the sleeve; an insertion strip is provided on the right side of the opening; a fixing sleeve is movably fitted on the outer surface of the insertion strip; the fixing sleeve is fixedly connected to the front of the tool holder; and a limit block is fixedly connected to the right side of the insertion strip. The rotating tool holder is fixed by the insertion of the fixing strip into the fixing seat. In use, the spring inside the sleeve will push the fixing strip upward to achieve the function of inserting the fixing strip. By inserting the insertion strip through the opening into the through hole on the fixing strip and pulling the fixing strip downward, the fixing of the rotating tool holder is released. The limit block on the right side of the insertion strip can limit the insertion strip to prevent the limit block from slipping off the inner surface of the fixing sleeve.

[0011] Preferably, the number of the water inlet tank, pipe interface, fixing pin, cutter pad, cutter head, water baffle, and fixing seat is two. Water is introduced into the water inlet tank through the two pipe interfaces, and the water flows out from the gap between the cutter head and the cutter pad through the outlet of the water inlet tank, thereby cooling the cutter head. The water baffle below the cutter head directs the cooling water downwards, thereby preventing the flowing water from interfering with the processing of the cutter head.

[0012] Preferably, the two fixing seats are adapted to the fixing strip. The two fixing seats allow the two cutter heads to switch freely and be fixed under the action of the rotating shaft, achieving a rapid switching function.

[0013] Preferably, the outer surface of the fixing strip is in movable contact with the inner surface of the sleeve. The fixing strip is extended and retracted on the inner surface of the sleeve to fix the fixing seat, thereby achieving the purpose of fixing the rotating tool holder.

[0014] Preferably, the insert is adapted to the opening and the through hole. By inserting the insert through the opening into the through hole on the fixing strip and pulling the fixing strip downward, the fixing of the rotating tool holder is released.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a cutting tool with a cooling function, which has the following beneficial effects:

[0017] 1. This cutting tool with a cooling function allows two cutting heads to be freely switched and fixed by a rotating shaft via two fixed seats, achieving rapid switching. Water is introduced into a water inlet tank through two pipe interfaces, and the water flows out from the gap between the cutting head and the cutting pad through the outlet of the water inlet tank, thus cooling the cutting head. A water baffle under the cutting head directs the cooling water downwards, preventing flowing water from interfering with the machining process. This device can cool the cutting tool by introducing cooling water, and can quickly switch to another cutting tool to ensure continuous machining. The temperature of the switched-off cutting tool gradually decreases, facilitating continuous machining and effectively solving the problem of overheating.

[0018] 2. This type of tool with a cooling function uses a fixing strip to secure the rotating tool holder through an insertion connection between the fixing strip and the fixing base. During use, a spring inside the sleeve pushes the fixing strip upwards, thus securing it. By inserting the insert strip through the opening into the through hole on the fixing strip and pulling it downwards, the tool holder is released from its fixation. A limiting block on the right side of the insert strip prevents it from slipping off the inner surface of the fixing sleeve. This device effectively secures the rotating tool holder, facilitating rapid switching between the two tools on the rotating tool holder to ensure continuous machining and is easy to use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] like Figure 1-3 As shown, this utility model provides a cutting tool with a cooling function, including a tool holder 1, and a cutting tool mechanism 2 is provided above the tool holder 1;

[0027] The cutting tool mechanism 2 includes: a rotating tool holder 201, which is rotatably connected to the tool holder 1 via a rotating shaft 202. A water inlet groove 203 is provided above the rotating tool holder 201, and a pipe interface 204 is provided above the water inlet groove 203. The pipe interface 204 is fixedly connected to the top of the rotating tool holder 201. Tool pads 206 and tool heads 207 are fixedly installed on the left and right sides of the rotating tool holder 201 via fixing pins 205. A water baffle 208 is fixedly connected below the tool head 207. Fixing seats 209 are fixedly connected to the front and back of the rotating tool holder 201. There are two water inlet grooves 203, pipe interfaces 204, fixing pins 205, tool pads 206, tool heads 207, water baffles 208, and fixing seats 209.

[0028] In this embodiment, two fixed seats 209 allow the two cutting heads 207 to be freely switched and fixed under the action of the rotating shaft 202, achieving rapid switching. Water is introduced into the water inlet tank 203 through two pipe interfaces 204. The water flows out from the gap between the cutting head 207 and the cutting pad 206 through the outlet of the water inlet tank 203, achieving the purpose of cooling the cutting head 207. The water baffle 208 below the cutting head 207 directs the cooling water downwards, preventing the flowing water from interfering with the processing of the cutting head 207. This device can cool the cutting tool by introducing cooling water, and can quickly switch to another cutting tool to ensure processing continuity. The temperature of the switched-off cutting tool will gradually decrease, facilitating continuous processing and effectively solving the problem of overheating.

[0029] Example 2

[0030] like Figure 1-3 As shown, based on Embodiment 1, this utility model provides a technical solution: a fixing mechanism 3 is provided on the front of the knife handle 1;

[0031] The fixing mechanism 3 includes: a sleeve 301, which is fixedly connected to the front of the tool holder 1. A fixing strip 303 is elastically connected to the inner surface of the sleeve 301 via a spring 302. A through hole 304 is provided in the middle of the fixing strip 303. The fixing strip 303 is inserted into the fixing seat 209 through an insertion hole. An opening 305 is provided on the right side of the sleeve 301. An insert strip 306 is provided on the right side of the opening 305. A fixing sleeve 307 is movably fitted on the outer surface of the insert strip 306. The fixing sleeve 307 is fixedly connected to the front of the tool holder 1. A limit block 308 is fixedly connected to the right side of the insert strip 306. Two fixing seats 209 are adapted to the fixing strip 303. The outer surface of the fixing strip 303 is movably fitted to the inner surface of the sleeve 301. The insert strip 306 is adapted to the opening 305 and the through hole 304.

[0032] In this embodiment, the rotating tool holder 201 is fixed by inserting the fixing strip 303 into the fixing base 209. During use, the spring 302 inside the sleeve 301 pushes the fixing strip 303 upwards, thus achieving the function of inserting the fixing strip 303. By inserting the insert 306 through the opening 305 into the through hole 304 on the fixing strip 303, the fixing strip 303 is pulled downwards, thereby releasing the fixing of the rotating tool holder 201. The limiting block 308 on the right side of the insert 306 can limit the insertion 306, preventing it from slipping off the inner surface of the fixing sleeve 307. This device effectively fixes the rotating tool holder 201, facilitating rapid switching between the two tools on the rotating tool holder 201 to ensure continuous processing and is easy to use.
